[0017] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is now further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the relevant components of the utility model.

[0018] According to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

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

[0020] Embodiment 1, as Figure 1 and Figure 2 As shown, a multi-joint hanger for prefabricated cable trenches includes a hanger beam 1, a rope plate 2, a hook 3 and a steel wire rope 4, wherein the hanger beam 1 is assembled by welding, and the hook 3 is a self-locking hook during implementation, which has the function of preventing the hanging parts from falling off, and is particularly suitable for suspending small cable trench prefabricated parts. The hanger beam 1 is set as a truss structure, which has a simple structure, low cost and safety.

[0021] The top of the hanging beam 1 is connected to the steel wire 4, and the steel wire 4 is pulled and lifted by a crane or a crane. The bottom two sides of the hanging beam 1 are fixedly connected to the rope plate 2 respectively. The rope plate 2 is evenly provided with a plurality of rope holes 21 along the extension direction of the hanging beam 1. The rope plate 2 is connected to the hook 3 through the rope holes 21 and the hanging rope 31. Through the rope holes 21 on the rope plate 2, multiple prefabricated cable trench components can be lifted at one time, which can improve the lifting efficiency of the prefabricated cable trench, reduce labor costs and improve lifting safety.

[0022] Because rope plates 2 are arranged on both sides of the bottom of the lifting beam 1, when lifting the prefabricated cable trench components, each concrete prefabricated component uses two hooks, which can improve the lateral stability of the component during the lifting process. After the lifting, the prefabricated cable trench components have been arranged in a certain order, which also saves the time of rearrangement.

[0023] During implementation, specifically, the suspension beam 1 includes a top connection part 11, a tie rod 12, a bottom connection part 13, and a side rod 14. Both sides of the top connection part 11 are welded together with the bottom connection part 13 through the tie rod 12, and both ends of the top connection part 11 are welded together with the bottom connection part 13 through the side rod 14.

[0024] In addition, for example, to facilitate lifting with the steel wire rope 4, a lifting lug 41 is provided at the top of the top connection part 11, and the top connection part 11 is connected to the steel wire rope 4 through the lifting lug 41 to form a stable pulling. For example, to facilitate pulling, at least two lifting lugs 41 can be provided, and the multi-link hoist is lifted by passing one or more steel wire ropes 4 through the lifting lugs 41.

[0025] Embodiment 2, on the basis of embodiment 1, a reinforcing rib 16 is further connected between the top connecting portion 11 and the bottom connecting portion 13, the reinforcing rib 16 is arranged obliquely, and the reinforcing rib 16 and the pull rod 12 form a triangular fixing structure. After the reinforcing rib 16 is installed, the overall stability of the suspension beam 1 can be improved, and higher load performance can be provided.

[0026] As a preferred solution, a strip-shaped hole-adjusting plate 15 is fixed to the top of the top connection part 11, and mounting holes are evenly opened on the hole-adjusting plate 15. The hole-adjusting plate 15 is connected to the lifting lug 41 through the mounting holes and screws. By setting the hole-adjusting plate 15, the position of the upper hanging point can be adjusted, which is suitable for the state of eccentric loading, and the best position can be determined after trial hanging.

[0027] When implementing, see Figure 4 Two lifting ears 41 are symmetrically arranged at the same position on the top of the top connection part 11, and the middle part is connected by a pin 42, and the wire rope 4 is wound around the pin 42. That is to say, two lifting ears 41 form a group and are installed on the top connection part 11, and at least two groups are arranged on the top connection part 11. The wire rope 4 is wound around the pin 42 to automatically adjust the pulling force point, thereby lifting the multi-link hoist.

[0028] Example 3, based on Example 1 or 2, please refer to Figure 4 The interior of the suspension beam 1 is also provided with a support rod 17, which is vertically arranged, and at least one support rod 17 is provided to stably support the interior of the suspension beam 1. The top of the support rod 17 is fixedly connected to the top connection part 11, and the bottom of the support rod 17 is fixedly connected to the bottom connection part 13. In this embodiment, the top connection part 11 is a truss welded by angle steel, and the bottom connection part 13 can also be a truss structure welded by angle steel.

[0029] As a preferred solution, the bottom two sides of the bottom connecting part 13 are fixedly connected to the rope plate 2, and a fastener 22 is provided on the outer side of each rope hole 21 on the bottom connecting part 13. The fastener 22 is a U-shaped structure with mounting holes on both sides, and is used to be nested on the outer side of the rope hole 21 when in use, so as to improve the fastening of the hanging rope 31 and prevent the small contact area from being easily worn.

[0030] The multi-joint lifting device described in the above three embodiments is used to lift the multi-joint lifting device to a designated position above the precast concrete component of the cable trench to be lifted by a crane. After it is lowered to a certain height, the worker connects the hook 3 on the lifting device to the lifting ring on the component. Each cable trench component is connected with two hooks 3, which can improve the stability of the component during lifting. After connecting multiple cable trench components, the on-site workers will pre-lift them and confirm that there is no unhooking before carrying out the formal lifting work. After the operation reaches the designated location, it will be slowly lowered. After the cable trench concrete component is stably lowered, the hook 3 and the lifting ring are removed. At this time, the lifting operation of the precast concrete component of the cable trench is completed.

[0031] It is worth noting that during the production process, two lifting points are embedded in the prefabricated concrete components of the cable trench, and they are arranged in order after production is completed. After the prefabricated cable trench components are hoisted, they have been arranged in a certain order, which also saves the time of rearrangement. Each cable trench component is connected with two hooks, which can control the displacement of one degree of freedom of the cable trench component during the lifting process and ensure the stability during the lifting process. After the workers connect multiple cable trench components, they pre-lift the multi-link hoist and confirm that there is no unhooking before carrying out the formal lifting work. During the lifting process, it is necessary to always observe whether the posture of the hoisting device has undergone significant deformation or overturning. After the lifting operation reaches the designated location, it is slowly lowered. After the concrete components are stably lifted, the hooks and rings are removed. The lifting operation of the prefabricated concrete components is completed, and the components are also placed in an orderly manner.

[0032] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
