The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a hoist is used in section of jurisdiction hoist and mount which characterized in that: the pipe piece lifting device comprises a screw rod, the screw rod is arranged on the pipe piece in a penetrating mode, one end, located on the inner side of the pipe piece, of the screw rod is provided with a first nut, one end, located on the outer side of the pipe piece, of the screw rod is provided with a second nut, gaskets are arranged between the first nut and the second nut and the pipe piece respectively, one end, located on the outer side of the pipe piece, of the screw rod is provided with a lifting block, and a lifting hole is formed in the lifting block.
Preferably, the washer is connected with a second nut, and the hanging block is connected with the second nut and moves up and down along with the second nut relative to the screw rod. The gasket, the hanging block and the second nut are connected together, so that the lifting appliance is more favorable for assembly and is convenient and fast to use.
In order to facilitate hoisting, preferably, the hoisting block is in an inverted U shape, the hoisting block is fastened on the second nut in a riding mode, the bottom of the hoisting block is connected with the gasket, and the hoisting hole is formed in the top end of the hoisting block. .
Preferably, the width of the U-shaped groove of the hanging block is the same as the outer diameter of the second nut, and the height of the U-shaped groove of the hanging block is 1.5-3 times of the height of the second nut. The width of the U-shaped groove of the hanging block is the same as the outer diameter of the second nut, and the hanging block can be buckled on the second nut and is beneficial to subsequent welding. The height of the U-shaped groove is 1.5-3 times of the height of the second nut, and an up-and-down moving space of the screw rod relative to the second nut is provided.
Preferably, the hanging block is made of steel, the gasket comprises a steel plate, the hanging block is welded to the steel plate, and the inner side wall of the U-shaped groove of the hanging block is fixedly welded to the second nut.
In order to avoid hard contact between the gasket and the segment, the gasket preferably comprises a steel plate and an elastic gasket positioned between the steel plate and the segment.
Compared with the prior art, the utility model has the advantages that: according to the utility model, the duct piece is limited between the two gaskets through the first nut and the second nut on the screw rod, and the duct piece is firmly fixed on the lifting appliance, so that the duct piece is fixed relative to the lifting appliance in the lifting process, the safety in lifting is improved, and meanwhile, the lifting appliance is simple, easy to assemble and strong in practicability.
