Abstract

The utility model relates to an oil-pressure jacking pipe synchronizing bar. An oil-pressure jacking pipe comprises a mud pressing-in pipe at the upper part, a mud discharge pipe at the lower part, and surrounding supporting bodies. The upper position and the lower position of a partition plate are symmetrically hinged in the middles of a shank A and a shank B. A cutter body A and a cutter body B are respectively and fixedly arranged at the left ends of the shank A and the shank B. A plurality of T cutters are arranged on the two cutter bodies. The right end of the shank A and the right end of shank B are hinged through an oil pressure driver. The oil-pressure jacking pipe synchronizing bar is characterized in that the upper end of the synchronizing bar is hinged with a pin A at the left end of the shank A, the lower end of the synchronizing bar is hinged with a pin D at the right end of the shank B, the pin A is arranged between the pin B and the cutter body A, the pin D is arranged between a pin C and a lower telescopic shaft, and the distance between the pin A and the pin B is equal to the distance between the pin C and the pin D.

Description

Oil pressure push pipe synchronizing bar

Technical field

The utility model relates to the oil pressure push pipe synchronizing bar of a kind of push pipe synchronizing bar, particularly a kind of jacking construction machinery.

Background technology

The cutter hub of the push pipe of oil pressure actuated, during work, can not carry out real synchronous, if a cutter hub runs into very large resistance, this cutter hub will be slack, only has another cutter hub motion, so causes asynchronous, also to push pipe, bring very large reactive torque, cause the push pipe displacement.

Summary of the invention

The utility model has made up the shortcoming of above oil pressure push pipe, and a kind of oil pressure push pipe synchronizing bar is provided.

The utility model is achieved by the following technical solution:

A kind of oil pressure push pipe synchronizing bar, wherein, the oil pressure push pipe comprises that the mud on top is pressed into pipe, the mud discharge piping of bottom and the supporter of surrounding, the symmetrical hinged handle of a knife A of demarcation strip upper-lower position, the centre of handle of a knife B, handle of a knife A, the left end of handle of a knife B is fixed cutter body A respectively, cutter hub B, on two cutter hubs, be equipped with many T cutter, the right-hand member of the right-hand member of handle of a knife A and handle of a knife B is hinged by the oil pressure actuated device, its special character is: synchronizing bar upper end hinged handle of a knife A left end pin A, lower end hinged handle of a knife B right-hand member pin D, pin A is located between pin B and cutter hub A, pin D is located between pin C and lower telescopic shaft, the distance of pin A and pin B equals the distance of pin C and pin D.

The utlity model has following characteristics:

The utility model synchronizing bar limit two cutter hubs always locking phase to moving up and down.

The accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is structural representation of the present utility model;

In figure: 1, T cutter, 2, cutter hub A, 3, cutter hub B, 4, supporter, 5, demarcation strip, 6, handle of a knife A, 7, handle of a knife B, 8, the oil pressure actuated device, 9, pin A, 10, the pin B, 11, the pin C, 12, the pin D, 13, upper telescopic shaft, 14, lower telescopic shaft, 15, the mud discharge piping, 16, mud is pressed into pipe, and 17, synchronizing bar.

The specific embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model, this embodiment comprises that the mud on top is pressed into pipe 16, the mud discharge piping 15 of bottom and the supporter 4 of surrounding, the symmetrical hinged handle of a knife A6 of demarcation strip 5 upper-lower positions, the centre of handle of a knife B7, handle of a knife A, the left end of handle of a knife B is fixed cutter body A2 respectively, cutter hub B3, on two cutter hubs, be equipped with many T cutter 1, the right-hand member of the right-hand member of handle of a knife A and handle of a knife B is hinged by oil pressure actuated device 8, its special character is: synchronizing bar 17 upper end hinged handle of a knife A left end pin A9, lower end hinged handle of a knife B right-hand member pin D12, pin A is located between pin B10 and cutter hub A, pin D is located between pin C11 and lower telescopic shaft 14, wherein, the distance of pin A and pin B equals the distance of pin C and pin D.

In the utility model when work,, the oil pressure actuated device is regular flexible, drives thus the upper and lower regular relative motion of two cutter hubs, synchronizing bar limit two cutter hubs always locking phase to moving up and down.
