Gapless hydraulic driving following support system

Abstract

The invention relates to a gapless hydraulic driving following support system, which comprises an upper cover, a jacket, an inner following sleeve, a hydraulic motor, a rotating plate, a following head and a following seat, wherein the inner following sleeve is connected with the jacket in a threaded manner and can move vertically along the jacket, and the hydraulic motor is arranged in the middle of the inner following sleeve and connected to the lower side of the upper cover by a support; the rotating plate is connected onto a rotary shaft of the hydraulic motor and is in transmission connection with the inner following sleeve in a threaded manner, and the following head is disposed on the lower side of the rotating plate and fixedly connected with the inner following sleeve; and the following seat is arranged on the lower side of the following head and movably connected with the following head. The gapless hydraulic driving following support system protects continuous gapless following of a protecting support device and a lifted heavy object in a protective supporting manner by the aid of spiral lifting, avoids impact of a supporting protection system on the lifted heavy object when a lifting system loses efficacy, and accordingly prevents damage to the lifted heavy object.

Description

technical field [0001] The invention relates to a construction equipment, in particular to a gapless hydraulic drive follow support system. Background technique [0002] The necessity to follow the support mainly comes from two aspects: [0003] ① There may be oil leakage in the hydraulic jacking system; the rupture of the oil pipe causes the failure of the support system during jacking. [0004] ②Due to the failure of the lifting and heightening oil roof and the pad structure below it, follow the support as a safety backup support. [0005] At present, there are mainly two ways of follow-up support in our country [0006] 1) Manual pad support: [0007] A copy pad is used to protect the support point next to each vertex, so as to achieve one copy at the top and copy at the other side; copy at the top and at the same time. The copying personnel do not prepare copying boards of various specifications at each copying point. Every time a certain height is reached, the Pu b...

Problems solved by technology

[0003] ① There may be oil leakage in the hydraulic jacking system; the rupture of the oil pipe causes the failure of the support system during jacking

The problem of manual copying pad support is: in the lifting of the same heavy object, the protectiveness of the pad copying personnel at each point often appears that the height of the protective pad copying at each point is different in a certain period of time, and it cannot be followed in time question

Disadvantages of displacement following support are: (1) Due to the uneven contact surface, the automatic following measurement and control error is large; at the same time, because there is no pre-pressure, the gap of its temporary structure will further affect the effective accuracy of the support; (2) Another set of 220V power supply is required. control system, which is used on temporary steel structures, and has extremely high requirements for leakage protection of temporary structures; (3) Since the drive motor device following the support system is installed externally, it is easy to be damaged during operation and handling, and it takes up a large space for jacking. Exposed, can not be used all day
