Problems solved by technology

[0004] When the oil inlet pipe 4 leaks, the seal is not tight, etc., it is necessary to fix the connector 5 and rotate the connector body 1 to completely separate the connector body 1 from the connector 5. Sometimes the connector 5 is not fixed tightly and the connector body 1 is difficult to unscrew. , reduce the replacement efficiency of the oil inlet pipe 4; when selecting the joint body 1, generally use a wrench to lock the joint body 1 and turn it out. Due to the manual disassembly method, the rotation angle of the wrench is limited, and it needs to be adjusted many times. Only when the joint body 1 is locked can the joint body 1 be unscrewed, which will greatly affect the replacement efficiency of the oil inlet pipe

Abstract

The invention relates to the field of maintenance equipment, and in particular, discloses a crane oil inlet pipe replacing device. A power mechanism in the device can drive a first rotating block anda second rotating block in a dismounting mechanism to quickly and horizontally move and rotate, so that a joint can be quickly screwed into a connecting head or screwed out from the connecting head; in the screwing-in and screwing-out process, a spring rod can slide in a first annular groove, a second annular groove, a third annular groove and a fourth annular groove; and distances between a firstrotating block and a second rotating block and between a first fixed block and a second fixed block are stable, so that stable and quick disassembly is realized.

Description

technical field [0001] The invention belongs to the field of maintenance equipment, in particular to a crane oil inlet pipe replacement device. Background technique [0002] The oil inlet pipe is a commonly used oil transportation pipe in the hydraulic system of the crane, but it is also the most prone to leakage in the hydraulic system. The common oil inlet pipe is connected to other pipes in the hydraulic system. Sleeve fittings for connection. [0003] Such as figure 1 As mentioned above, the ferrule-type pipe joint is composed of a joint body 1 with a tapered hole, a ferrule 2 and a compression nut 3. The compression nut 3 is threaded with the left end of the joint body 1 to realize the connection between the oil inlet pipe 4 and the joint body. 1; then the thread on the right end of the joint body 1 is threadedly connected with the connector 5 in the hydraulic system to realize the communication between the oil inlet pipe 4 and the hydraulic system. [0004] When the...
