Bed-railing rotating shaft combination jack capable of realizing loaded translation

Abstract

A bed-railing rotating shaft combination jack capable of realizing loaded translation is composed of a base frame combination, a force arm combination and a cable. Universal wheels, a bed-railing rotating shaft set, a winch and U-shaped vertical notches are arranged on the base frame combination, the force arm combination is a tip-tilted obtuse structure, round shafts are arranged on two sides ofa folded corner, and a cable fastening buckle is arranged at the head end of the force arm combination; the force arm combination is combined at the U-shaped vertical notches through the round shafts,one end of the cable is fastened on the cable fastening buckle at the head end of a force arm, wound on rotating shafts of the bed-railing set one by one and finally guided onto the winch, and by shaking the winch to pull the cable onto the winch, the tail end of the force arm can upwarp to jack up a thick and heavy cement prefabricated pipe and to support the cement prefabricated pipe for horizontal movement according to requirements on horizontal positioning of the cement prefabricated pipe. By the jack, only two operators are needed to accurately and easily complete docking of cement prefabricated pipe orifices which needs six or seven skilled and strong technicians to complete in a time-consuming and labor-consuming manner.

Description

Technical field: [0001] The invention relates to a jack, in particular to a bed-grid type rotating shaft combination jack capable of load-bearing translation. Background technique: [0002] At present, there is no jack capable of load-bearing translation. Therefore, when laying cement prefabricated pipes of certain specifications for underground drainage pipes, six or seven strong technicians are required to rely on pulley blocks and crowbars to operate. If it deviates, it is necessary to re-pry the horizontal position of the pipe and try to connect again. Often a group connection needs to be repeated many times before it can be successful, which is very time-consuming and laborious. Invention content: [0003] In order to improve the construction efficiency of related projects, the present invention provides a load-bearing translational bed-grid type rotating shaft combination jack, which is characterized in that the jack is composed of a set of base frame combination and...
