Abstract

An oil-pressure top pipe synchronous rod adopts the structure that an oil-pressure top pipe comprises a mud press-in pipe at the upper part, a mud discharge pipe at the lower part, and support rods at the periphery; partition plates are arranged up and down symmetrically and hinged to the middles of a shank A and a shank B; a blade A and a blade B are fixed at the left ends of the shanks (A and B) respectively; a plurality of T knives are arranged on each blade; the right end of the shank A and that of the shank B are hinged with each other through an oil-pressure driver. The oil-pressure top pipe synchronous rod is characterized in that a left end pin A of the shank A is hinged with the upper end of the synchronous rod; a right end pin D of the shank B is hinged with the lower end of the synchronous rod; the pin A is arranged between a pin B and the shank A; the pin D is arranged between a pin C and a lower telescopic shaft; the distance between the pin A and the pin B equals to that between the pin C and the pin D.

Description

Oil pressure push pipe synchronizing bar

Technical field

The present invention 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, can not carry out during work real synchronously, if a cutter hub runs into very big resistance, this cutter hub will be slack, has only another cutter hub motion, so causes asynchronous, also bring very big reactive torque to push pipe, cause the push pipe displacement.

Summary of the invention

The present invention has remedied the shortcoming of above oil pressure push pipe, and a kind of oil pressure push pipe synchronizing bar is provided.

The present invention is achieved through the following technical solutions:

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 supporter all around, the hinged handle of a knife A of demarcation strip upper-lower position symmetry, 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, be equipped with many T cutter on two cutter hubs, 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: the hinged handle of a knife A left end pin A in synchronizing bar upper end, and lower end hinged handle of a knife B right-hand member pin D, pin A is located between pin B and the cutter hub A, pin D is located between pin C and the following telescopic shaft, and the distance of pin A and pin B equals the distance of pin C and pin D.

The present invention has following characteristics:

Synchronizing bar of the present invention limit two cutter hubs always locking phase to moving up and down.

Description of drawings

The present invention is further illustrated below in conjunction with accompanying drawing:

Fig. 1 is structural representation of the present invention;

Among the 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, go up telescopic shaft, 14, telescopic shaft down, 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 invention, this embodiment comprises that the mud on top is pressed into pipe 16, the mud discharge piping 15 of bottom and supporter all around 4, the hinged handle of a knife A6 of demarcation strip 5 upper-lower positions symmetry, 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, be equipped with many T cutter 1 on two cutter hubs, 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 ends 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 the cutter hub A, pin D is located between pin C11 and the following telescopic shaft 14, wherein, the distance of pin A and pin B equals the distance of pin C and pin D.

When the present invention worked, the oil pressure actuated device was regular flexible, drove the regular relative motion up and down of two cutter hubs thus, synchronizing bar limit two cutter hubs always locking phase to moving up and down.
