Problems solved by technology
[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.

Embodiment Construction
[0006] Such as Figure 4 As shown, will figure 2 The moment arm combination shown is placed by the circular axis 8 figure 1 In the "U" shaped notch 4 provided on the shown base frame, one end of the cable 10 is bolted on the bolt cable buckle 9, and the remaining cables are first wound around the horizontal bar body shape closest to the bolt cable buckle in the form of a spring. On the first rotating shaft in the ladder format rotating shaft, then wind through each subsequent rotating shaft one by one, and finally the end of the cable is tied on the winch circumference 6. During application, push the slope surface 7 of the moment arm of the present invention from the lateral side of the cement prefabricated pipe to be sent to the lowest position on the lower side of the pipe body, shake the handle on the winch after clamping, and wind the cable Pull on the capstan and make the slope surface 7 of the arm of force lift against the relevant cement prefabricated pipe.

The invention relates to a novel translation ladder box type rotating shaft combined jack capable of bearing loads. The jack is formed by a bed frame combination and a force arm accompanied by mooringropes; universal wheels, ball type idler wheels, a ladder box type rotating shaft array and a winch, and U-shaped vertical notches are formed in the bed frame combination; the force arm is a tip-tilted obtuse-angle member, round shafts are arranged at the two sides of the bevel, and a mooring rope buckle is arranged at the head end; the force arm combination is combined to the U-shaped vertical notch of the bed frame combination through the round shafts, one end of the mooring rope is fixed to one mooring rope buckle at the head end of the force arm, then the mooring ropes are wound by the ladder box type array rotating shaft one by one and finally guided to the winch, the winch is shaken to pull the mooring rope to the winch so that the tail end of the force arm can be upwarped to jack athick and heavy cement pre-fabricated pipe up and jack the cement pre-fabricated pipe to move horizontally, and the cement pre-fabricated pipe orifice butt joint engineering can be completed accurately and easily by two operators, while 6-7 strong technicians are needed to complete the cement pre-fabricated pipe orifice butt joint engineering laboriously originally with much time consumed.
Description
Technical field: [0001] The invention relates to a jack, in particular to a novel load-bearing translational ladder shaft combination jack. 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 novel load-bearing translational ladder shaft combination jack, which is characterized in that the jack is composed of a set of base frame combination and a set of force arm combinati...
