Description

Technical Field

[0001] This utility model relates to the technical field of truss construction, and in particular to a truss hoisting and clamping device. Background Technology

[0002] A truss is a skeleton-type load-bearing structure formed by hinged or rigid connections of members. During construction, steel wire ropes are generally tied to the truss, and then the truss is lifted by hooking the hooks onto the steel wire ropes using a crane and anti-collision device for the crane disclosed in utility model patent CN214299017U, or a wheeled crane and connected vehicle disclosed in invention patent CN1259096B.

[0003] However, during construction, it was found that using a crane to lift the truss alone was inconvenient for fine-tuning the truss's position in narrow spaces or with large spans. Furthermore, each time steel wire ropes had to be tied, which was time-consuming, labor-intensive, and dangerous, resulting in poor practicality. Therefore, there is an urgent need for a truss lifting and clamping device to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a truss hoisting and clamping device that hangs a support mechanism on a crane hook and connects a clamping mechanism to a hydraulic device or the hydraulic system of the crane. The clamping mechanism clamps the truss in a suspension and external support manner, and then the crane lifts it up. After that, the level of the support mechanism is adjusted by an adjustment mechanism to maintain the stability of the truss. After moving to the designated position, the position of the truss is finely adjusted by the clamping mechanism to put the truss into place, thereby improving the practicality of the equipment.

[0005] This utility model discloses a truss hoisting and clamping device, which includes a support mechanism, an adjustment mechanism and a clamping mechanism, both of which are mounted on the support mechanism.

[0006] The supporting mechanism, in conjunction with the clamping mechanism, fixes the truss, while the adjusting mechanism adjusts the stability of the truss.

[0007] The support mechanism is hung on the crane hook, and the clamping mechanism is connected to the hydraulic equipment or the crane's hydraulic system. The truss is clamped by the clamping mechanism in a suspension and external support manner, and then lifted by the crane. The level of the support mechanism is then adjusted by the adjustment mechanism to maintain the stability of the truss. After moving to the designated position, the position of the truss is finely adjusted by the clamping mechanism to make the truss fit in place, thereby improving the practicality of the equipment.

[0008] Preferably, the support mechanism includes a frame, multiple sets of wire ropes, and lifting rings. The lifting rings are installed on the top of the frame via the multiple sets of wire ropes. The lifting rings are hung on hooks, and the frame supports the adjustment mechanism and clamping mechanism, thereby improving the practicality of the equipment.

[0009] Preferably, the adjustment mechanism includes a first water tank, a second water tank, and two sets of water pumps. The first water tank, the second water tank, and the two sets of water pumps are all installed on the top of the frame. The suction port of one set of water pumps is connected to the interior of the first water tank, the discharge port of one set of water pumps is connected to the interior of the second water tank, the suction port of the other set of water pumps is connected to the interior of the second water tank, and the discharge port of the other set of water pumps is connected to the interior of the first water tank. Water is poured into the first and second water tanks. After the crane lifts the truss, the water in the first water tank is drained into the second water tank by one set of water pumps, or the water in the second water tank is drained into the first water tank by the other set of water pumps, thereby adjusting the levelness of the truss and maintaining its stability.

[0010] Preferably, the clamping mechanism includes multiple sets of lifting trolleys, multiple sets of sliders, multiple sets of hydraulic cylinders, and multiple sets of hooks. The multiple sets of lifting trolleys are slidably mounted on the bottom of the frame. The multiple sets of sliders are slidably mounted on the bottom of the multiple sets of lifting trolleys. The multiple sets of hydraulic cylinders are fixedly mounted on the bottom of the multiple sets of lifting trolleys, with one end of each set of hydraulic cylinders connected to one set of sliders. The multiple sets of hooks are mounted on the bottom of each set of sliders. By retracting the multiple sets of hydraulic cylinders, the position of the multiple sets of sliders is adjusted. Then, the multiple sets of hooks hook the truss. Further extension of the multiple sets of hydraulic cylinders causes the hooks to press the truss outwards, clamping the truss using an external support clamping method. When the truss is lowered, the multiple sets of lifting trolleys slide on the frame. Then, by extending the front multiple sets of hydraulic cylinders and retracting the rear multiple sets of hydraulic cylinders, or by retracting the front multiple sets of hydraulic cylinders and extending the rear multiple sets of hydraulic cylinders, the position of the truss is finely adjusted to ensure precise positioning, thereby improving the practicality of the equipment.

[0011] Preferably, a leveling instrument is provided at the top center of the frame; the leveling instrument is used to detect the levelness of the frame, thereby obtaining the levelness of the truss and improving the practicality of the equipment.

[0012] Preferably, both water tank one and water tank two are equipped with electrically controlled valves at their bottoms; the water in water tank one and water tank two can be quickly discharged through the electrically controlled valves at their bottoms, which facilitates a rapid reduction in the weight of the equipment and thus improves the practicality of the equipment.

[0013] Preferably, both water tank one and water tank two are equipped with multiple sets of anti-wave nets inside; the multiple sets of anti-wave nets block the swaying water in water tank one and water tank two respectively, thereby ensuring the stability of the equipment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the support mechanism is hung on the hook of the crane, and the clamping mechanism is connected to the hydraulic equipment or the hydraulic system of the crane. The truss is clamped by the clamping mechanism in a suspension and external support manner, and then lifted by the crane. After that, the level of the support mechanism is adjusted by the adjustment mechanism to maintain the stability of the truss. After it is moved to the designated position, the position of the truss is finely adjusted by the clamping mechanism to make the truss fit into place, thereby improving the practicality of the equipment.
