Description

Technical Field

[0001] This utility model relates to the field of municipal engineering, specifically a lifting tool for pipeline construction in municipal engineering. Background Technology

[0002] Municipal infrastructure projects, or municipal engineering for short, encompass multiple projects, specifically referring to civil engineering, pipeline, and equipment installation works for urban roads, public transportation, water supply, drainage, gas, heating, landscaping, sanitation, sewage treatment, garbage disposal, flood control, underground public facilities, and ancillary facilities. When constructing water supply pipelines, it is necessary to move the pipelines from their storage location to the construction trench. Currently, the common practice is to tie the pipelines with ropes and then use the hooks of lifting equipment to attach the ropes for transfer. While rope tying can effectively lift and move water supply pipelines, this method is not standardized, and the ropes are only tied to the pipeline at one point, resulting in a small contact area and making the pipeline prone to swaying and instability. Furthermore, it provides poor support for the pipeline, and longer pipelines are susceptible to breakage in the middle, posing significant safety hazards.

[0003] Chinese utility model patent application number 202420669816.2 discloses an auxiliary tooling for lifting water conservancy pipelines, including a main lifting sling, a main connecting ring, a main detachable sling, and an adjustable hook assembly; two of each of the main lifting sling, main connecting ring, main detachable sling, and adjustable hook assembly are provided, and the main connecting ring is connected to one end of a corresponding main lifting sling, one end of an adjustable hook assembly, and a main detachable sling.

[0004] The aforementioned auxiliary lifting fixture for water conservancy pipelines uses two slings to secure the pipeline near both ends. This allows the ends of the pipeline to be directly aligned and connected with the ends of the preceding and following pipelines, making pipeline installation faster. Furthermore, an adjustable hook assembly secures the pipeline opening, preventing the slings from slipping inward and improving stability during lifting. However, the small contact area between the ropes and the pipeline still presents problems, resulting in poor support for the pipeline and a higher risk of breakage in the middle for longer pipelines. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a lifting fixture for municipal engineering pipeline construction. This lifting fixture has a splicable structure, and the splicing length can be adjusted according to the pipeline length to increase the contact area with the pipeline, improve stability, and provide support for longer pipelines in the middle position to prevent breakage. It is easy to operate and effectively solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifting fixture for municipal engineering pipeline construction, comprising several splicing units that can be horizontally spliced, each splicing unit comprising an elastic arc-shaped support plate, with horizontal sleeves fixedly provided at the front and rear ends of the arc-shaped support plate, arc-shaped lifting lugs fixedly provided on the upper surface of the sleeves, and connecting rods detachably inserted into the sleeves respectively.

[0007] As a preferred technical solution, the arc-shaped support plate includes an arc-shaped rubber block, in which first and second reinforcing ribs are interlaced and fixed to each other, forming an elastic support frame. The two ends of the support frame extend out of the rubber block and are fixedly connected to the outer bottom surface of the sleeve.

[0008] As a preferred technical solution, a limiting block is provided at the middle position inside the sleeve.

[0009] As a preferred technical solution, the length of the connecting rod is the same as the length of the sleeve.

[0010] As a preferred technical solution, the arc-shaped lifting lug is fixed at the center position of the upper surface of the sleeve.

[0011] As a preferred technical solution, the inner surface of the arc-shaped support plate is provided with a guide to facilitate its lateral pull-out from the bottom of the pipe.

[0012] As a preferred technical solution, the guide includes several fixed pulleys that can roll back and forth. The other side of the fixed pulley relative to the rolling part is fixedly connected to one end of the connecting rib, and the other end of the connecting rib extends into the rubber block and is fixedly connected to the support frame.

[0013] As a preferred technical solution, the fixed pulleys are distributed on the inner surfaces of the front and rear ends and the bottom of the rubber block, with each fixed pulley being distributed laterally at intervals.

[0014] Compared with the prior art, this utility model provides a lifting fixture for pipeline construction in municipal engineering, which has the following beneficial effects:

[0015] 1. This utility model includes a flexible arc-shaped support plate in each splicing unit. Transverse sleeves are fixed at both ends of the arc-shaped support plate, and arc-shaped lifting lugs are fixed on the upper surface of the sleeves. Connecting rods are detachably inserted into the sleeves. In use, the arc-shaped support plate initially has an arc-shaped structure. An appropriate number of arc-shaped support plates can be selected according to the pipe length, and the arc-shaped support plates are spliced ​​together using the connecting rods. Then, the middle position of the pipe is placed on the spliced ​​arc-shaped support plate. The front and rear arc-shaped lifting lugs of the leftmost and rightmost arc-shaped support plates are hooked to rope hooks, and the ropes are then connected to lifting equipment. This provides support and assists in lifting the pipe in the middle position, increasing the contact area, improving stability, and preventing breakage in the middle position. After lifting to the trench and connecting the pipe, the arc-shaped lifting lugs on the front of the left and right ends of the arc-shaped support plates can be hooked to remove the entire arc-shaped support plate, thus improving the standardization of the operation.

[0016] 2. This utility model uses an arc-shaped support plate including an arc-shaped rubber block. The rubber block is provided with interlaced first and second reinforcing ribs that are fixed to each other, forming an elastic support frame. The two ends of the support frame extend out of the rubber block and are fixedly connected to the outer bottom surface of the sleeve. In use, the rubber block protects the pipe and prevents slippage. The elastic support frame gives the arc-shaped support plate a certain degree of elasticity, allowing it to deform and making it easy to remove from the bottom of the pipe.

[0017] 3. This utility model has a limiting block in the middle of the sleeve. When the arc-shaped support plate is spliced ​​with the connecting rod, the limiting block can limit the insertion position of the connecting rod, thus improving the convenience of operation.

[0018] 4. The inner surface of the arc-shaped support plate is provided with a guide to facilitate its lateral pull-out from the bottom of the pipe. The guide includes several fixed pulleys that can roll back and forth. The other side of the fixed pulley relative to the rolling part is fixedly connected to one end of the connecting rib. The other end of the connecting rib extends into the rubber block and is fixedly connected to the support frame. In use, the fixed pulleys reduce the friction between the arc-shaped support plate and the pipe in the back and forth direction, making it easy for the arc-shaped support plate to be pulled out from one side after construction.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0030] like Figures 1 to 5 As shown, a lifting fixture for municipal engineering pipeline construction includes several horizontally splicing units. Each splicing unit includes an elastic arc-shaped support plate 1. A transverse sleeve 2 (with an outer diameter smaller than the thickness of the arc-shaped support plate 1 to avoid excessive friction and impact on the outer surface of the pipeline 4) is fixedly mounted on the upper surface of both ends of the arc-shaped support plate 1. An arc-shaped lifting lug 21 is welded and fixed to the upper surface of the sleeve 2, and the arc-shaped lifting lug 21 is fixed at the center of the upper surface of the sleeve 2. Connecting rods 3 (for splicing adjacent arc-shaped support plates 1) are detachably inserted into the sleeve 2. The arc-shaped support plate 1 includes an arc-shaped rubber block 10. The rubber block 10 has interlocking first reinforcing ribs 11 and second reinforcing ribs 12, forming an elastic support frame. Both ends of the support frame extend out of the rubber block 10 and are welded and fixedly connected to the outer bottom surface of the sleeve 2.

[0031] A limiting block 22 is provided in the middle position inside the sleeve 2.

[0032] The length of connecting rod 3 is the same as the length of the sleeve.

[0033] In use, the initial state of the arc-shaped support plate 1 is an arc-shaped structure. An appropriate number of arc-shaped support plates 1 can be selected according to the length of the pipe 4. The arc-shaped support plates 1 are then spliced ​​together using connecting rods 3 (the overall spliced ​​length is half the length of the pipe 4). The middle position of the pipe 4 is then placed on the spliced ​​arc-shaped support plate 1. Finally, the front and rear arc-shaped lifting lugs 21 of the leftmost and rightmost arc-shaped support plates 1 are hooked and connected to the hooks 51 of the rope 5 (see...). Figure 4 The rope 5 is then connected to the lifting equipment, which supports and assists in lifting the pipe 4 in the middle position, increasing the contact area, improving stability, and preventing breakage in the middle. After the pipe 4 is connected at the trench, the arc-shaped lifting lugs 21 on the front side of the arc-shaped support plate 1 at both ends can be hooked to remove the arc-shaped support plate 1 as a whole, improving the standardization of the operation. The rubber block 10 protects and prevents slipping of the pipe 4. The elastic support frame gives the arc-shaped support plate 1 a certain degree of elasticity, allowing it to deform and facilitating removal from the bottom of the pipe 4. When the arc-shaped support plate 1 is spliced ​​by the connecting rod 3, the limiting block 22 can limit the insertion position of the connecting rod 3 (preventing one side from being inserted too deeply and the other side from being inserted too shallowly during splicing), improving the convenience of operation. Example 2

[0034] like Figures 6 to 8 As shown, the inner surface of the arc-shaped support plate 1 is provided with a guide to facilitate its lateral pull-out at the bottom of the pipe 4.

[0035] The guide includes several fixed pulleys 6 (existing technology) that can roll back and forth. The other side of the fixed pulleys 6 relative to the rolling part is fixedly connected to one end of the connecting rib 13, and the other end of the connecting rib 13 extends into the rubber block 10 and is fixedly connected to the support frame.

[0036] Fixed pulleys 6 are distributed on the inner surface of the front and rear ends and bottom of the rubber block 10, with each fixed pulley 6 being distributed laterally at intervals.

[0037] When in use, the fixed pulley 6 reduces the friction between the arc-shaped support plate 1 and the pipe 4 in the front-to-back direction (and has a limiting effect in the left-to-right direction), making it easy for the arc-shaped support plate 1 to be pulled out from one side as a whole after construction.
