Technical Description and Content
1 Device Overview
Equipment Name: 5T Self-Propelled Trackless Manipulator (7 Degrees of
Freedom), Model: DZW-5-7(Z)
1.2：Device Function。This self-propelled
manipulator is wheeled and diesel-powered, capable of moving freely, and
can grip cold/hot billets or forgings within the rated load. It can
perform the following seven actions: wheel forward/backward, wheel
steering, clamp rotation, parallel lifting of the clamp arm, horizontal
cushioning of the clamp arm, tilting of the clamp arm, and
opening/closing of the clamp jaws. The entire machine operates flexibly
and can conveniently work with a hydraulic press to complete the forging
of billets.
1.3：Equipment Requirements
Mobile and flexible: starts quickly, accelerates smoothly, stepless
speed control, brakes quickly and smoothly, and changes direction
without jerking; suitable for working in harsh environments such as
forging and high temperatures, with stable and reliable performance; has
a small turning radius, allowing for easy operation even in relatively
confined spaces.
2 Structural Function Description
2.1 Overall structure
This self-propelled operating machine uses a diesel engine with
hydraulic transmission, rear-wheel drive and steering, and front-wheel
braking. It features a modular design, making replacement and
maintenance quick and convenient. The clamp arm is lifted using a
parallel four-bar linkage, allowing for parallel lifting and tilting.
The clamp arm can tilt to grip workpieces from the ground. The hydraulic
components should be installed as far from heat sources as possible, or
provided with effective protection, to extend their service life.
2.2 Vehicle movement, braking, and steering
The vehicle frame is made of high-quality steel plates welded
together, effectively eliminating welding stress; the frame features
a 'П'-shaped design, allowing the center of the clamp rod to descend
to a very low position. The diesel engine fuel tank and hydraulic oil
tank are both positioned within the vehicle frame, saving space, making
the structure more compact, and enhancing equipment stability.
The travel mechanism consists of four sets of steel rubber wheels,
with one set on the left and right sides at the front of the vehicle
for load-bearing, and two sets in the center at the rear primarily for
controlling the travel direction.
Rear-wheel drive: The rear wheels are directly driven by a low-speed,
high-torque hydraulic motor.
Front-wheel brakes: Standard braking devices are installed on the
two front wheels of the vehicle to enable vehicle travel braking.
Vehicle steering: A slewing bearing is installed on the rear wheel
turning disc, driven by a hydraulic motor rotating a small gear, which
in turn drives the slewing disc and rear wheel steering, allowing the
vehicle to turn while moving.
The wheels all use steel hubs, covered with a thick layer of
wear-resistant rubber, and come with heat-insulating protective
covers.
2.3 Clamping mechanism
The clamping mechanism is divided into two parts: the clamp
head and the clamp body. It has two actions: clamp head clamping and clamp
head rotation, and is the core part of the forging manipulator.
The clmp head consists of a clamp yoke, clamp arm, clamp jaw, pin shaft,
welding.
The hollow shaft is fixed to the clamp frame through the front and rear
bearings (double-row tapered roller bearings and self-aligning roller
bearings). The clamping cylinder is connected to the clamp arm via a
connecting plate and uses an accumulator for pressure maintenance.
The clamp jaw is connected to the clamp arm via a pin shaft. However,
when clamping a workpiece, the pin shaft does not bear the force; the
force-bearing surface is the matching arc between the clamp arm and the
clamp jaw, which provides a large contact area. All pin shafts are
designed with a stepped shaft structure, making them easy to dismantle
and convenient for maintenance.
Clamp clamping
The structure of the clamp section is reasonably designed, sturdy,
and durable, with a high clamping torque.
It uses a specially designed clamping mechanism: driven by a hydraulic
cylinder, pressure maintained by an accumulator, hydraulic oil supplied
through a rotary joint, a force-enhancing mechanism, and cylinder-driven
clamping. The piston rod of the clamping cylinder is fixed, and the clamp
head is operated through the movement of the cylinder body.
The clamping cylinder is equipped with an accumulator to maintain
pressure, and the hydraulic oil required for the clamping cylinder is
supplied through a hydraulic rotary joint. It features high-pressure
clamping, which can be adjusted from the control console
Clamp Rotation
The rotating components of the clamp rotation drive system are firmly
supported and driven by a hydraulic motor, providing significant driving
power. The clamp rotation uses a hydraulic motor with a gearbox + slewing
gear pair for rear drive. The small gear on the output shaft of the gearbox
meshes with the large gear located on the hollow shaft, transmitting the
rotational power to the hollow shaft of the clamp. The hollow shaft is
integrated with the clamp bolt, thereby driving the clamp to rotate.
Controlled by an electro-hydraulic proportional directional valve, it
features a short response time, enhancing the sensitivity of clamp
rotation speed adjustment, allowing the clamp to start and stop smoothly,
with stepless speed adjustment.
2.4 Power, hydraulics, control systems
The power system of this equipment is driven by a diesel engine that
powers a hydraulic pump, with the hydraulic system using a closed-loop
variable piston pump plus a dual gear pump.
The hydraulic system's valve assembly is divided according to function,
facilitating fault detection and maintenance.
The control hydraulic system is supplied by a separate hydraulic pump
set, independent of the working hydraulic oil, ensuring stable and
reliable control oil pressure.
Operating system: Various actions are performed through multi-way
directional valves, pilot-assisted joysticks, hydraulic power steering
(steering wheel), pilot-assisted foot pedals, and fully hydraulic power
brake valves, etc.
The cab is fully enclosed with heat insulation and is equipped with a
dedicated air conditioning system and shock-absorbing seats.
The equipment is equipped with a reverse radar camera system and an
audible-visual driving alarm system.
The driving method of this equipment is similar to that of an excavator,
making operation simple, convenient, safe, and comfortable.
