Description
Technical field
The present invention relates to a kind of hydraulic tongs is and in particular to a kind of portable liquid pressing tongs for bead string rope coupling compression joint.
Background technology
Need for the two ends of bead string rope to be joined together to form closed ring by beading rope socket before rope saw work,
Again bead string rope is installed on rope sheave.Adopting sheet metal joint beading rope socket, due to sheet metal material hardness very more
Height, is not easy to be crimped shaping, even if sheet metal joint is crimped shaping, crimp force also be difficult to control zone of reasonableness
Interior, bead string rope one end can be led to deviate from from beading rope socket if crimp force is too small, crimp force is crossed conference and led to beading rope socket
By pressure break or fine crack occurs, thus have impact on the stability connecting between beading rope socket and bead string rope.At present, a lot
Crimper great majority adopt mechanical type, and thrust is relatively small, can run into much to completing bead string rope coupling compression joint shaping work
Difficulty, even if employing reinforcement mode, crimp force nor setting, is not easy to the operation of bead string rope coupling compression joint.

It is contained on compacting part, two crimping modules are slidably mounted on jaw relatively, and pressure setting part is arranged in the second blind hole,
Oil-feed part is mounted on the pincers pump housing between the first blind hole and the second blind hole, and draining part is near the fixing peace of the first blind hole
It is contained on the side wall of the pincers pump housing, and positioned at being machined with spill port between the draining part on the pincers pump housing and the second blind hole, pressurization moves
Fixed handle and pressure release lever are disposed side by side on the pincers pump housing along pincers pump housing circumferencial direction, and one end of pressure release lever is hinged
It is arranged on the side wall of the pincers pump housing, piezometry valve and elastic load pin are oppositely arranged on the side wall of the pincers pump housing, piezometry
Valve is arranged on the side wall of the pincers pump housing and extend into the second oil circuit in the hole of pressure setting part, and one end of elastic load pin is close
Draining part is fixedly mounted on the side wall of the pincers pump housing, and the other end of elastic load pin withstands on pressure release lever, oil conservator
It is sleeved on successively from inside to outside on the lateral wall of the second blind hole with main handle, one end of pressurization moving handle is hingedly mounted on
On the side wall of the pincers pump housing, the projection on pressurization moving handle withstands on oil-feed part.
The method have the advantages that the portable liquid pressing tongs for bead string rope coupling compression joint of the present invention can be by
Bead string rope steel joint once crimps shaping, and bead string rope two ends are connected reliable, by invention to beading rope socket with steel joint
Crimping is to be crimped according to pre-set crimp force, and crimp force can control in rational scope, is not in
Crimp force too small or excessive and cause bead string rope one end from beading rope socket abjection or beading rope socket by pressure break, beading rope socket
Connect reliable and stable and bead string rope between, occur without fatigue damage.Corresponding pressure welding mold is selected according to bead string rope and joint specification
Block, adjustment pressure setting part is adapted between the bead string rope of different size and joint setting maximum pressure value, hydraulic tongs
Crimping operation it is ensured that crimp quality between bead string rope and joint, hydraulic tongs employs hydraulic coupling mode, and operation saves
Power, the sealing ring using all size is sealed, and sealing effectiveness is good, occurs without oil leakage phenomenon, working site is not produced
Pollution.The hydraulic tongs small volume of the present invention is easy to carry, simple to operate flexible.

Operation principle
Portable liquid pressing tongs is by the use of hydraulic oil as the working media of transmission power, first converts mechanical energy into during work
Hydraulic energy, then hydraulic energy is converted into mechanical energy, promote the crimping module 2 at jaw 1 mobile and compress bead string rope steel joint,
Bead string rope and steel joint are crimped together.During portable liquid pressing tongs operation, the steel wire rope at bead string rope two ends is inserted by operator
Enter bead string rope steel joint in the hole, by aligned in position to be crimped with bead string rope steel joint for the crimping module 2 of hydraulic tongs, one
Hold the main handle 9 of hydraulic tongs, another handss back and forth press pressurization moving handle 10, drive the sucking type in oil-feed part 4
Piston 4-5 moves back and forth, and hydraulic oil is constantly drawn into oil-feed part the first check valve 4-1 and oil-feed part from oil conservator 8
In the cavity in oil circuit hole between two check valve 4-2, hydraulic oil is pressed into compacting part piston 5-3 and the first blind hole 3-1 again
In cavity, compacting part piston 5-3 is promoted to move forward, thus promoting crimping module 2 to move forward and produce certain pressure, will
Bead string rope steel joint crimps into the hexagon shape corresponding with the pressure mouth-shaped of two crimping modules 2.Compression when hydraulic tongs
In cavity between part piston 5-3 and the first blind hole 3-1, the pressure of hydraulic oil exceedes the setup pressure value of pressure setting part 7
When, the pressure in pressure setting part 7 sets valve element 7-4 and can be backed down, and hydraulic oil can flow back in oil conservator 8, at this moment operates
Person can feel to pressurization moving handle 10 operating pressure be obviously reduced, show hydraulic tongs to bead string rope steel joint crimping work
Pressure has reached requirement, and crimping work has completed.Operator presses pressure release lever 12, opens draining part check valve
6-1, under the reset pressure of piston spring 5-5 acts on, compacting part piston 5-3 is moved rearwards by, and hydraulic oil proceeds by draining,
It flow back into oil conservator 8, crimping module 2 is opened, the jaw 1 of hydraulic tongs is opened, take out hydraulic tongs.
