Press-type multi-purpose pulling device

Abstract

The invention discloses a multipurpose treading type pulling and jacking device. The multipurpose treading type pulling and jacking device comprises a jacking and pulling device, a control device, a treading device, a hydraulic rod, a piston, a hydraulic cylinder, a tray, a valve body and a valve. The hydraulic cylinder is screwed on the upper portion of the center line of the tray, the hydraulic rod with the piston is installed in a center barrel of the hydraulic cylinder, and a standby assembly is connected to the upper end of the hydraulic rod. The multipurpose treading type pulling and jacking device has the advantages of being convenient to use, safe, reliable, simple in structure, and wide in application range; the pulling and jacking device can be suitable for different positions and shapes of various force bearing points and is away from a workpiece in the jacking operating process, the pulling and jacking device is safe, reliable, high in working efficiency, simple in structure, low in machining cost, and easy and convenient to operate with less effort, and operation against rules is eliminated.

Problems solved by technology

[0002] At present, in the construction machinery maintenance and installation industry, hydraulic jacks are often used to lift objects. The existing hydraulic jacks have many shortcomings, and there are potential safety hazards. During use, jacking objects often slip, fall, crush and kill people. ACCIDENT

In the automobile maintenance industry, it is often necessary for maintenance personnel to use hydraulic jacks to lift the vehicle body under the vehicle. During the lifting process, the vehicle body will tilt forward or backward, and the tilting force will cause the vehicle body to move and crush the operator.

The equipment maintenance process often requires a variety of safe and reliable jacking force points to lift objects. However, the existing hydraulic jacks at home and abroad have a single purpose, which is not satisfactory and can only lift objects vertically. It cannot be applied horizontally at any angle, nor can it be operated outside the safe distance of the components. There are too few functions, and it is extremely inconvenient to use. It is often necessary to process additional workpieces for lifting and pulling that are in contact with the workpiece, which is a waste of time and labor. low
