Detailed Description
As shown in fig. 1, 2 and 3, the utility model comprises a rectangular top plate 1 horizontally arranged, a lifting rope connecting hole 2 is respectively arranged on the top plate corresponding to 4 corners, and a vertical rod 3 vertical to the top plate is respectively welded on the bottom surface of the top plate at the position of 4 corners of the top plate; two clamping rods 4 are respectively arranged between every two vertical rods 3 on two opposite sides of the top plate, an upper shaft barrel 5 is welded between the upper ends of the two clamping rods, a lower shaft barrel 6 is welded between the middle parts of the two clamping rods, the upper half part of each clamping rod 4 is of a straight structure, and the lower half part of each clamping rod 4 is of an arc structure bent towards the opposite side of the top plate; a rotating shaft 7 penetrating through the clamping rod 4 and the lower shaft barrel 6 is inserted between the lower ends of the two vertical rods 3 on each side of the top plate, the two ends of the rotating shaft 7 respectively protrude out of the two vertical rods and are in threaded connection with a limit nut 8, and a bolt 9 penetrating through the clamping rod 4 and inserted into the upper shaft barrel 5 is movably inserted close to the upper ends of the two vertical rods 3 respectively.
With the above structure, when the latch 9 is removed, the clamping rod 4 can rotate around the rotating shaft 7, and the rotating state is shown in fig. 4.
The purpose of the clamping rod rotating structure is to enable the clamping rods 4 on the two sides of the lifting appliance to be capable of opening for a certain angle to form a pincer-shaped structure, so that the concrete pipe can be conveniently embraced or clamped. In order to limit the rotation angle of the clamping rod 4 to be too large, a limiting rod 10 can be welded between the outer sides of the two vertical rods on each side of the top plate, and the limiting rod 10 is parallel to the rotating shaft 7 and is positioned above the vertical rods where the rotating shaft is arranged.
The utility model discloses during the concrete implementation, the roof adopts the steel sheet of certain thickness. In order to reduce the weight of the top plate, two or more lightening holes 11 can be formed in the top plate 1, and the two or more lightening holes 11 are symmetrically arranged on two sides of the transverse or longitudinal center line of the top plate 1.
In order to strengthen the whole structure of the lifting appliance, a triangular reinforcing plate 12 can be welded between one side of each vertical rod provided with a bolt and the top plate. When the reinforcing plate covers the position of the pin shaft arranged on the vertical rod, a pin hole can be formed in the corresponding position of the reinforcing plate, so that the bolt 9 can be conveniently installed.
The utility model discloses during the preparation, the diameter setting of the concrete pipe of the size as required hoist and mount of hoist, the interval of roof both sides montant should equal or slightly be greater than the diameter of concrete pipe.
As shown in fig. 5 and 6, the utility model discloses during the use, be connected 4 lifting rope connecting holes on lifting rope and the roof, insert the bolt in the axle sleeve on taking off the montant, hang the hoist with the loop wheel machine to concrete pipe 13 top, the clamping bar 4 of hoist both sides opens certain angle to both sides, detain the both sides at concrete pipe 13 respectively, then the manual work rotates clamping bar 4, it is parallel with the montant to make the clamping bar rotate first, and insert bolt 9 and fix clamping bar 4, the arc part of hoist both sides clamping bar 4 is relative this moment, embrace concrete pipe 13. And hoisting by using a crane, hoisting the concrete pipe to a position to be installed by using the hoisting tool, then taking down the bolt again to open the clamping rods at the two sides, hoisting the hoisting tool away by using the crane, and returning to hoist the next section of concrete pipe.
