Description

Technical Field

[0001] This utility model relates to the technical field of concrete pipe gallery construction equipment, and more specifically, to a hoisting clamp for concrete pipe gallery components. Background Technology

[0002] With the advancement of urban integrated utility tunnel construction, the hoisting of concrete utility tunnel components has become a key part of construction. In the early days, hoisting relied on traditional methods such as through-hole hoisting and tie-on hoisting, which were prone to damage to components and lacked safety. With the development of prefabricated construction technology, special hoisting clamps have gradually replaced traditional hoisting tools and are evolving towards being adjustable and highly adaptable.

[0003] A search revealed that Chinese Patent Publication No. CN108584691A discloses "a lifting clamp, comprising a first clamping arm with a first clamping plate, a second clamping arm with a second clamping plate, a first roller within the first and second clamping plates, the first roller meshing with a first gear, the first gear coaxially connected to a second gear, the second gear meshing with a third gear, and the third gear meshing with a rack; a first slide rod and a second slide rod within the first and second clamping plates; a toggle rod within the first and second clamping plates; and an alarm device within the first and second clamping plates; as the tubular component moves axially, the first roller drives the first or second slide rod to apply external force to the tubular component, preventing further movement of the tubular component. This invention can clamp and lift tubular components and also has the advantage of timely control of the axial movement of the tubular component." However, it still has the following drawbacks: (1) In actual use, the device has insufficient clamping adaptability and adjustment accuracy, which can easily lead to hoisting risks. It relies on gears, racks and slides to achieve basic clamping, and cannot accurately adjust the clamping position according to the length of the pipe gallery components. The force is easily unbalanced, which makes it difficult to meet the requirements of high-value prefabricated pipe gallery components for clamping accuracy and multi-specification adaptability, thus indirectly reducing hoisting efficiency. (2) In actual use, the protective performance of the device is lacking, which can easily cause damage to the components. The hard contact fixation by the clamping plate can easily lead to cracking of the corners and surface damage of the concrete pipe gallery, which does not meet the requirements of the integrity of the appearance and structural safety of the components during the hoisting process, and will also increase the subsequent repair costs. Therefore, a hoisting clamp for concrete pipe gallery components is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the problems that current hoisting clamps for concrete pipe gallery components lack adaptability and adjustment precision, making it difficult to meet the requirements of pipe gallery components for clamping accuracy and multi-specification compatibility, indirectly reducing hoisting efficiency, failing to meet the requirements of component appearance integrity and structural safety during hoisting, and increasing subsequent repair costs. This utility model provides a hoisting clamp for concrete pipe gallery components to solve the above problems.

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0016] Example: Figure 1-5 As shown, this embodiment proposes a hoisting clamp for concrete pipe gallery components, including a movable frame 1, a clamping component 2 fixedly installed at the bottom of the movable frame 1, and a protective component 3 fixedly installed on one side of the clamping component 2. like Figure 2-5 As shown, the clamping assembly 2 includes a first motor 201 fixedly mounted on one side of the movable frame 1. A threaded post 202 is fixedly mounted on the output end of the first motor 201, penetrating the movable frame 1. A movable block 203 is threadedly mounted on the periphery of the threaded post 202. An adjusting groove 204 is fixedly mounted on the bottom of the movable block 203. A second motor 205 is fixedly mounted on one side of the adjusting groove 204. A bidirectional lead screw 206 is fixedly mounted on the output end of the second motor 205, penetrating the adjusting groove. Two adjusting blocks 207 are threadedly mounted on the periphery of the bidirectional lead screw 206. A limiting groove 208 is fixedly mounted on the bottom of the adjusting block 207. A support shell 209 is fixedly mounted on the bottom of the limiting groove 208. A third motor 210 is fixedly mounted on the top of the support shell 209. A rotating post 211 is fixedly mounted on the output end of the third motor 210. A gear 212 is fixedly mounted on the periphery of the rotating post 211. The limiting groove 208... Two racks 213 are inserted and installed at the bottom of the device. The racks 213 mesh with the gears 212. An L-shaped clamping plate 214 is fixedly installed on one side of the racks 213. In use, the first motor 201 drives the threaded column 202 to rotate, which drives the moving block 203 and the bottom adjustment groove 204 to move back and forth. The clamping position can be adjusted according to the length of the pipe gallery component to ensure balanced force. The second motor 205 drives the bidirectional lead screw 206 to rotate, so that the two adjustment blocks 207 move closer or further away from the lead screw synchronously, which can adapt to the clamping width requirements of pipe galleries with different diameters. The third motor 210 drives the gear 212 to rotate through the rotating column 211, which meshes with the two racks 213 in the limiting groove 208 to drive the L-shaped clamping plate 214 to open and close quickly, so as to achieve stable clamping of the pipe gallery component. Through coordinated control, it can flexibly adapt to concrete pipe gallery components with different cross sections such as straight and curved, and avoid the risk of component tilting and falling off due to clamping offset during hoisting.

[0017] like Figure 5As shown, the protective component 3 includes a protective groove 301 opened on one side of the L-shaped clamping plate 214. Several buffer columns 302 are fixedly installed on one side of the protective groove 301. Buffer springs 303 are fixedly installed on the periphery of the buffer columns 302. A protective pad 304 is fixedly installed on the side of the buffer column 302 away from the protective groove 301. In use, the several buffer columns 302 in the protective groove 301, together with the periphery buffer springs 303, provide flexible buffering when the L-shaped clamping plate 214 clamps the component, avoiding the component's corners from cracking and surface damage caused by rigid clamping. The protective pad 304 (made of high-elasticity rubber) at the end of the buffer column 302 contacts the surface of the pipe gallery, which not only increases the contact area to disperse the clamping force, but also isolates the metal L-shaped clamping plate 214 from hard contact with the concrete, further protecting the integrity of the component's appearance. While ensuring stable clamping, it minimizes the risk of damage during the component's hoisting process, adapting to the hoisting needs of high-value, high-precision prefabricated pipe gallery components.

[0018] like Figure 2 and Figure 4 As shown, pressure sensors 4 are fixedly installed on one side of the two protective pads 304, and controllers 5 are fixedly installed on one side of the two L-shaped clamping plates 214. Controllers 5 are electrically connected to pressure sensors 4. Indicator lights 6 are fixedly installed on one side of controllers 5 and are electrically connected to controllers 5. The pressure sensors 4 are Honeywell FP5000. During use, the pressure sensors 4 on the protective pads 304 monitor the clamping force in real time and transmit the data to controllers 5 on the L-shaped clamping plates 214. When the clamping force is too small, controllers 5 drive indicator lights 6 to flash red and issue a warning, reminding operators to adjust the clamping force to prevent components from slipping during hoisting. When the clamping force is too large, controllers 5 send a signal to the third motor 210 to automatically fine-tune the clamping force to prevent the concrete pipe gallery from cracking due to excessive compression. The brightness of indicator lights 6 can intuitively reflect the clamping status (green light for normal, red light for abnormal), greatly improving the safety of hoisting operations and adapting to high-altitude hoisting scenarios for large pipe gallery components.

[0019] like Figure 3 and Figure 4 As shown, several support columns 7 are fixedly installed on the top of the limiting groove 208, and a rain shield 8 is fixedly installed on the top of the support columns 7. Several water guide grooves 9 are opened on the top of the rain shield 8. In use, the support columns 7 on the top of the limiting groove 208 fix the rain shield 8. It is specially designed for the complex environment of outdoor hoisting in municipal engineering. The several water guide grooves 9 on the top of the rain shield 8 can quickly guide rainwater and prevent rainwater from seeping into the interior of the limiting groove 208, preventing the core components from rusting and corroding. The rain shield 8 can block dust, sand and other impurities from entering the transmission structure, preventing gear 212 from meshing and jamming and affecting clamping accuracy. It provides protection for hoisting operations under different outdoor weather conditions (rainy days, dusty days) and is suitable for the working conditions of pipe gallery construction sites with a lot of dust and easy rain.

[0020] like Figure 5 As shown, several warning light covers 10 are fixedly installed on one side of the two L-shaped clamping plates 214. Light tubes 11 are fixedly installed inside the warning light covers 10. When in use, the several warning light covers 10 on one side of the L-shaped clamping plates 214 cover the internal light tubes 11. When hoisting in low visibility environments such as at night, on cloudy days, or in tunnels, the light tubes 11 emit conspicuous warning light (red light or yellow light can be selected) to remind the surrounding construction personnel to avoid collisions between components and personnel or equipment during hoisting. The warning light covers 10 have anti-drop and waterproof characteristics, adapt to the bumps and rain erosion of outdoor construction, improve the safety of operation, and meet the needs of continuous construction of pipe gallery projects.

[0021] like Figure 5 As shown, several anti-slip patterns 12 are fixedly installed on one side of the L-shaped clamping plate 214. When in use, the anti-slip patterns 12 on one side of the L-shaped clamping plate 214 are specially designed for the rough characteristics of the concrete surface, which greatly increases the contact friction between the clamping plate and the pipe rack components. During the high-altitude hoisting process, the components are subject to slight shaking or wind, and the anti-slip patterns 12 can also effectively prevent the components from sliding relative to each other. The anti-slip patterns 12 adopt wear-resistant metal processing technology, and are not easily worn when clamping concrete components for a long time, ensuring the stability of friction during multiple batches of hoisting, and adapting to the hoisting needs of rough surfaces and heavy weight of pipe rack components.

[0022] like Figure 2 As shown, a lifting ring 13 is fixedly installed on the top of the mobile frame 1. The lifting ring 13 is used for hoisting. During use, the lifting ring 13 on the top of the mobile frame 1 serves as the core connection between the clamp and the hoisting equipment. It is forged from high-strength alloy material and is adapted to the hoisting weight requirements of large concrete pipe gallery components. The installation position of the lifting ring 13 is precisely aligned with the center of gravity of the clamp to ensure that the overall force is balanced during hoisting and to avoid the pipe gallery components becoming unbalanced due to the clamp tilting. The ring structure design of the lifting ring 13 is compatible with hoisting ropes and hooks of different specifications. It is easy to install and disassemble without special tools and can be quickly connected to various hoisting equipment, providing a stable foundation for the hoisting operation of the entire clamp.

[0023] Working Principle: This utility model provides a hoisting clamp for concrete pipe gallery components. The specific usage steps are as follows: First motor 201 drives the threaded column 202 to rotate, causing the moving block 203 and bottom adjusting groove 204 to move back and forth. The clamping position can be adjusted according to the length of the pipe gallery component to ensure balanced force. Second motor 205 drives the bidirectional lead screw 206 to rotate, causing the two adjusting blocks 207 to move synchronously closer or further away along the lead screw, adapting to the clamping width requirements of pipe galleries with different diameters. Third motor 210 drives the gear 212 to rotate through the rotating column 211, meshing with the two racks 213 in the limiting groove 208, driving the L-shaped clamping plate 214 to open and close quickly, achieving stable clamping of the pipe gallery component. Through coordinated control, it can flexibly adapt to concrete pipe gallery components with different cross-sections such as straight and curved shapes, avoiding the risk of component tilting or falling off due to clamping offset during hoisting (e.g., ...). Figure 2-5 As shown), several buffer columns 302 within the protective groove 301, in conjunction with peripheral buffer springs 303, provide flexible buffering when the L-shaped clamping plate 214 clamps the component, preventing edge chipping and surface damage caused by rigid clamping. The protective pads 304 (made of highly elastic rubber) at the ends of the buffer columns 302 contact the surface of the pipe gallery, increasing the contact area to disperse the clamping force and isolating the metal L-shaped clamping plate 214 from hard contact with the concrete, further protecting the integrity of the component's appearance. While ensuring stable clamping, this minimizes the risk of damage during component hoisting, adapting to the hoisting needs of high-value, high-precision precast pipe gallery components (such as...). Figure 5 (As shown).

[0024] All technical features in this embodiment can be freely combined according to actual needs.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
