Description

Technical Field

[0001] This utility model relates to the field of sewage treatment pond construction, and in particular to an auxiliary hoisting device. Background Technology

[0002] Wastewater treatment tanks are usually located underground or semi-underground. Their walls, roofs, and pipes are mostly made of heavy concrete or precast steel structures. High hoisting accuracy is required during the hoisting process to avoid collisions or positional shifts. However, the cranes or hoists that can lift the tanks are often a certain distance away from the hoisting point to ensure the support strength around the installation site, making it difficult to observe and achieve high-precision hoisting. Therefore, an auxiliary hoisting device is needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide an auxiliary hoisting device, which has the advantages of assisting hoisting, improving the accuracy of the hoisting landing point and the stability of the hoisting process.

[0004] This utility model provides an auxiliary hoisting device for assisting a crane or gantry crane in lowering prefabricated components of a sewage treatment tank. The device includes a frame and a lowering assembly slidably connected to the frame. The frame is placed on top of the sewage treatment tank construction trough. The lowering assembly includes a slide block, a rope retractor, and a support rod. The frame has sliding grooves on its left and right sides, and the slide block engages with the sliding grooves. The rope retractor is located above the slide block and lowers a pull rope. The pull rope is connected to the support rod through the sliding grooves. When the prefabricated sewage treatment tank component is placed on the support rod, the rope retractor lowers the support rod along with the crane or gantry crane.

[0005] Furthermore, the device also includes transition rollers, a plurality of which are arranged in parallel within the frame member.

[0006] Furthermore, the device also includes a moving component that is connected to and drives the frame member to move.

[0007] Furthermore, the moving assembly has two sets and is symmetrically arranged at both ends of the frame member. The moving assembly includes a rotary motor, a connecting rod, and a base rod. The two rotary motors are symmetrically arranged on both sides of the frame member. One end of each of the two connecting rods is connected to the two rotary motors respectively, and the other end of each connecting rod is rotatably connected to the left and right sides of the base rod respectively.

[0008] Furthermore, the slide block is equipped with an electric roller at the engagement point with the sliding groove, which drives the slide block to slide.

[0009] By adopting the above technical solution, the beneficial effects of this utility model are:

[0010] This invention utilizes a frame structure to support the top of a pre-excavated wastewater treatment tank construction trench, thereby enhancing overall stability. A lowering assembly, in conjunction with a crane or gantry, assists in securing the prefabricated components as they enter the trench, increasing stability and ensuring accurate placement. Transition rollers, positioned on the ground around the trench, provide a transition section for the crane or gantry to adjust the component's position, further improving stability as the prefabricated components enter the lowering assembly. A movable assembly enables equidistant movement of the frame structure, improving consistency and countability of movement and reducing the difficulty of moving the frame.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0030] Reference Figure 1-3 This utility model provides an auxiliary hoisting device for assisting a crane or gantry crane in lowering prefabricated components of a sewage treatment tank.

[0031] The hoisting device includes a frame component 1, a lowering assembly 2, a transition roller 3, and a moving assembly 4.

[0032] Frame component 1 is placed on top of the wastewater treatment tank construction trough. Lowering component 2 is slidably connected to frame component 1. Lowering component 2 includes a slide block 21, a rope retractor 22, and a support rod 23. Sliding grooves 11 are provided on the left and right sides of frame component 1. The slide block 21 engages with the sliding grooves 11. An electric roller 5 is provided at the engagement point of the slide block 21 with the sliding groove 11, driving the slide block 21 to slide along the sliding groove 11. The rope retractor 22 is located above the slide block 21 and lowers a pull rope 24. The rope retractor 22 uses electric rotation control to retract and extend the pull rope 24. The pull rope 24 is connected to the support rod 23 via the sliding groove 11. When the prefabricated wastewater treatment tank component is placed on the support rod 23, the rope retractor 22 lowers the support rod 23 along with the crane or gantry crane, and the lowering speed of the rope retractor 22 is less than the downward speed of the crane or gantry crane. Several transition rollers 3 are arranged parallel to each other within the frame member 1, with some of the transition rollers 3 on the frame located above the ground. A moving assembly 4 is connected to the frame member 1 and drives the frame member 1 to move. To ensure the consistency and countability of the movement, there are two sets of moving assemblies 4 symmetrically arranged at both ends of the frame member 1. The moving assembly 4 includes a rotary motor 41, connecting rods 42, and a base rod 43. The two rotary motors 41 are symmetrically arranged on both sides of the frame member 1, one end of each connecting rod 42 is connected to the two rotary motors 41, and the other end of each connecting rod 42 is rotatably connected to the left and right sides of the base rod 43.

[0033] Working principle: The prefabricated component 1 is erected above the pre-dug sewage treatment tank construction trench using a seasonal frame component 1. A crane or gantry crane is then used to slide the prefabricated component on the transition roller 3 for posture adjustment. The component then reaches the support rod 23, where the position and distance of the two lowering components 2 are adjusted. As the crane or gantry crane lowers the prefabricated component, the rope retractor 22 pulls the rope 24 below, causing the support rod 23 to descend along with the prefabricated component. When position adjustment is needed, the rotary motor 41 is started, driving the connecting rod to rotate. Once the bottom rod 43 contacts the ground, it supports the frame component 1 and allows it to move.

[0034] It should be understood that the embodiments disclosed herein are not limited to the specific processing steps or materials disclosed herein, but should be extended to equivalent substitutions of such features as understood by those skilled in the art. It should also be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.
