Problems solved by technology

There are integral type, split type, electric type, manual type, etc. The existing hydraulic pliers do not have a pressure display device, and users often need to apply pressure according to their own experience, which often results in damage to the pliers due to excessive pressure. Or due to insufficient pressure and insufficient pressure, the maintenance work cannot be completed, time-consuming and laborious, the operation process is cumbersome, and the work efficiency is reduced

Embodiment 1

[0019] A hydraulic tong, comprising a main tong 1 and a back tong 2, the main tong 1 is provided with a speed change mechanism 3, the main tong 1 is connected to the back tong 2 through a guide rod 4, and the speed change structure 3 is provided with a hydraulic control module 5, The backup tongs 2 are fixedly connected on the base plate 6, the base plate 6 is provided with a connecting frame 7, and the connecting frame 7 is connected with the maintenance operation fuselage.

Embodiment 2

[0021] Example 2 as figure 1 As shown, it is improved on the basis of Embodiment 1, and its bottom plate 6 and connecting frame 7 are flexibly connected by steel wire ropes. The flexible connection is respectively used to set the bottom plate 6 and the connecting frame 7. The flexible connection mechanism also includes a buffer assembly and an induction module connecting the bottom plate 6 and the connecting frame 7, and the bottom plate 6 is movable relative to the connecting frame 7. , the flexible connection is more flexible and more variable, and the connection distance can be adjusted.

Embodiment 3

[0023] Example 3 as figure 1 As shown, it is improved on the basis of Embodiment 1. Its main tongs 1 are provided with a pressure gauge 8. There are pointers on the pressure gauge 8. The power source is supplied by a control circuit or a dry battery, and the pressure change of the main tongs is always concerned. According to The pressure display operation can effectively protect the hydraulic clamp. The mechanical pressure gauge or electronic hydraulic gauge is used to display the pressure index, which directly and effectively ensures the safe working and use of the hydraulic tongs.

Abstract

The invention discloses a hydraulic clamp which belongs to the technical field of hydraulic equipment and components. The hydraulic clamp comprises a main clamp 1 and a back clamp 2, wherein a speed changing mechanism 3 is disposed on the main clamp 1; the main clamp 1 is connected to the back clamp 2 by guide rods 4; a hydraulic control module 5 is disposed on the speed changing structure 3; the back clamp 2 is firmly connected to a baseplate 6; a connecting frame 7 is disposed on the baseplate 6; the connecting frame 7 is connected to a maintenance operation machine body; and the baseplate (6) and the connecting frame (7) are flexibly connected by a steel wire rope. A pressure gauge 8 is disposed on the main clamp 1; a pressure relief switch 9 is disposed on the hydraulic control module 5; an adjustable limiting block 10 is disposed on the main clamp 1; by the main clamp with the pressure gauge, an operator can observe pressure changes of the main clamp all the time and can carry out operations according to pressure display, so that the hydraulic clamp can be effectively protected; and the pressure relief switch 9 can be used to adjust pressures in the main clamp in time, so that use safety of the main clamp can be ensured, and thus personal safety of the operator can be ensured. The hydraulic clamp has the advantages that the structure is simple; use is convenient, safe and reliable; labor strength can be effectively reduced; consumption of time and efforts can be reduced; working efficiency is increased; maintenance or disassembly is convenient; and the production cost is reduced.

Description

technical field [0001] The invention relates to hydraulic equipment and components, in particular to a safe and convenient hydraulic device with a visual pressure gauge, which can automatically adjust the pressure, in particular a hydraulic clamp. Background technique [0002] In the oil field and other on-site operations, the main work is to disassemble and connect various workpieces. Taking oil field workover work as an example, hydraulic pliers are used to connect or disassemble oil pipes or sucker rods and other workpieces. Hydraulic pliers are applied Pliers hydraulic tools based on Pascal's principle. Crimping and cut-off functions are common. There are integral type, split type, electric type, manual type, etc. The existing hydraulic pliers do not have a pressure display device, and users often need to apply pressure according to their own experience, which often results in damage to the pliers due to excessive pressure. Or because the pressure is not enough, the pr...
