DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] As attached Figure 1-4 As shown, a lifting auxiliary device comprises a connecting seat 1 and a guide rail 9, wherein a lifting mechanism 2 and at least three pillars 3 are fixedly arranged on the connecting seat 1, wherein the three pillars 3 form a triangular bracket; at least three guide rails 9 are provided, and at least three guide rails 9 are arranged parallel to each other in the horizontal direction; a movable caster 4 is provided at the bottom of the pillar 3, and the movable caster 4 is located in a guide groove 91 of the guide rail 9 and is rollingly connected to the groove wall of the guide groove 91. The number of guide rails 9 is equal to the number of pillars 3.

[0021] The use of the utility model is explained by taking the transportation of water-stop steel plates in the construction of airport cable wells as an example. When in use, at least two guide rails 9 are pre-set on both sides of the cable wellhead 8, and at least one guide rail 9 is located between the two guide rails 9 on both sides of the cable wellhead 8. The length direction of the guide rails 9 is arranged along the horizontal straight transportation path of the water-stop steel plates. When transporting the water-stop steel plates, the triangular bracket is translated along the guide rails 9 to the initial storage position of the water-stop steel plates. At this time, the lifting mechanism 2 is located directly above the water-stop steel plates. After the lifting mechanism 2 lifts and fixes the water-stop steel plates, the operator pushes the triangular bracket so that the lifting mechanism 2 drives the water-stop steel plates to move horizontally to directly above the cable wellhead 8. After the operator operates the lifting mechanism 2 to lower the water-stop steel plates into the cable well and remove the water-stop steel plates, the lifting and transportation of the water-stop steel plates is completed. The utility model replaces manual lifting and transporting of the water-stop steel plate by setting a hoisting mechanism 2, replaces manual horizontal movement of the water-stop steel plate by setting a triangular bracket that reciprocates horizontally along the guide groove 91, and enables the triangular bracket to run smoothly horizontally by setting movable casters 4 on the pillars 3, thus saving manpower and improving operation safety. The utility model can also be used for hoisting and horizontal transport of other goods. The above is only to explain the specific embodiments of the utility model, and is not a limitation on the application scenarios of the utility model.

The connecting seat 1 is generally assembled and welded with steel materials such as steel pipes, steel plates, channel steels or angle steels. The lifting mechanism 2 is used to drive the lifting and reciprocating motion of materials such as water-stop steel plates. The lifting mechanism 2 can be an electric hoist, a hand chain hoist, a motor-driven synchronous belt lifting structure or a chain lifting structure. Preferably, the lifting mechanism 2 is a hand chain hoist, which is a lifting mechanism with a simple structure and easy to carry. There are many optional models, which are convenient for purchase and installation. The chain of the hand chain hoist is generally located at the center of the horizontal plane of the triangular support. Manually pulling the hand chain on the hand chain hoist requires the body to tilt toward the center of the support, which is laborious and poses a safety hazard. As a further preferred embodiment, a manual winch 5 is further included which is mounted on the pillar 3. A pull rope 52 is wound around the manual winch 5. One end of the pull rope 52 is located on the manual winch 5. The extended end of the pull rope 52 is connected to the hand chain of the hand winch. By rotating the manual winch 5 to change the length of the extended end of the pull rope 52, the pull rope 52 pulls the hand chain of the hand winch to make the hook 21 on the hand winch move up and down, thereby controlling the lifting and lowering movement of the water-stop steel plate, which is more convenient and safer than directly pulling the hand chain of the hand winch manually. The manual winch 5 and the pillar 3 can be fixed by welding, or fixed by bolts, pins or other structures. Preferably, a U-shaped mounting plate is provided on the manual winch 5, the pillar 3 is located in a U-shaped groove of the U-shaped mounting plate, a threaded hole is provided on the side wall of the U-shaped groove, a positioning bolt is threadedly installed in the threaded hole, the positioning bolt is pressed against the pillar 3 to position the manual winch 5 on the pillar 3, and the position of the manual winch 5 in the axial direction of the pillar 3 can be adjusted by adjusting the positioning bolt, so that the operator can adjust the height position of the manual winch 5 according to his own height, which is convenient for the operator to operate and reduces labor intensity.

[0023] The pillar 3 is used to support the lifting mechanism 2 so that there is a distance between it and the ground so that heavy objects can be lifted. The pillar 3 can be a solid columnar structure or a hollow tubular structure, and a common round steel pipe or square steel pipe can be used. The pillar 3 can be a single steel pipe or column structure with a fixed length, or a telescopic rod with a locking mechanism and adjustable length.

[0025] The angle between the pillar 3 and the connecting seat 1 can be fixed and non-adjustable. When the wellhead is too wide or the volume of the hoisted object is large, the original device may not meet the lifting requirements, and a lifting auxiliary device of suitable size needs to be remade. In addition, this structure is not conducive to the storage and transportation of the device. Specifically, the pillar 3 and the connecting seat 1 are hinged by a hinge shaft 7, and the hinge shaft 7 is perpendicular to the swing surface of the pillar 3; an adjustment positioning mechanism 6 is provided between the pillar 3 and the connecting seat 1. The pillar 3 is rotated to rotate around the hinge shaft 7 to adjust the angle between the pillar 3 and the connecting seat 1, and then the angle between any two pillars 3 can be flexibly adjusted, and the bottom spacing between any two pillars 3 can be changed. The pillars 3 are fixed in place by adjusting the positioning mechanism 6 to ensure the relative position between the pillars 3 during use. The utility model can be used for lifting and transporting goods of different sizes, and can also be applied to construction sites with different wellhead diameters. After use, the angle between multiple pillars 3 can be adjusted to the minimum to make multiple pillars 3 close together, which is convenient for manual handling and hoisting and saves handling space.

[0026] The adjustment and positioning mechanism 6 has a variety of structural forms, which can be a fastening bolt for fastening the pillar 3 to the connecting seat 1, a top screw structure for abutting the pillar 3, a plurality of positioning pins or limit blocks, etc. Preferably, the adjustment and positioning mechanism 6 includes a first connecting plate 61 arranged on the connecting seat 1, a second connecting plate 62 arranged on the pillar 3, and a fastening bolt 63 and a fastening nut 64 for fastening the first connecting plate 61 and the second connecting plate 62 together; the first connecting plate 61 and the second connecting plate 62 are both provided with arc through holes, the fastening bolt 63 penetrates the arc through holes on the first connecting plate 61 and the second connecting plate 62, and the fastening bolt 63 and the fastening nut 64 cooperate with each other to fasten the first connecting plate 61 and the second connecting plate 62. Loosening the fastening nut 64 can adjust the relative position of the first connecting plate 61 and the second connecting plate 62 so that the angle between the pillars 3 can be adjusted. After the angle adjustment of the pillar 3 is completed, tighten the fastening nut 64 to fasten the first connecting plate 61 and the second connecting plate 62 again. The structure is simple and the angle adjustment is convenient. The first connecting plate 61 and the second connecting plate 62 can be in any shape, such as arc, rectangle, circle or other plate-like structures, and the curvature and radius of the arc-shaped through holes on the two can be the same or different.
