Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for building construction, and in particular to a precast component hoisting and positioning buckle structure. Background Technology

[0002] With the rapid development of prefabricated building technology, precast components have been widely used in modern construction projects due to their advantages such as high construction efficiency and controllable quality. During the transportation and installation of precast components, hoisting operations are a crucial step. To ensure the safety and efficiency of the operation, specialized hoisting clamps or jigs are usually used to connect the precast components to the hoisting equipment, enabling the components to be transferred and positioned in the air.

[0003] However, existing precast component hoisting clamps still have certain structural defects in practical use. Currently, most common hoisting clamps on the market rely on manual adjustment of screws or locking mechanisms for fixation. Before lifting, operators need to spend a significant amount of time manually tightening the clamps to ensure a tight fit with the component. This method is not only labor-intensive and time-consuming, but also severely impacts construction efficiency.

[0004] Therefore, this utility model proposes a prefabricated component hoisting and positioning buckle structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In the existing technology, precast component hoisting equipment usually relies on manual tightening and fixing, which leads to cumbersome and time-consuming operation, low construction efficiency, and lack of a self-locking mechanism linked with the hoisting action. It is easy for the components to loosen in the air due to vibration or load changes, posing a significant safety hazard. This utility model aims to provide a precast component hoisting positioning buckle structure with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a precast component hoisting and positioning buckle structure, including: a base plate, a reciprocating swing mechanism and a hoisting and positioning buckle disposed on the upper part of the base plate, and a positioning mechanism disposed on the lower part of the base plate; the hoisting and positioning buckle includes a support column and a U-shaped ring connected to the top of the support column, and the bottom end of the support column extends through the base plate into the reciprocating swing mechanism.

[0007] The reciprocating swing mechanism includes a support rod, a movable plate, and a fixed rod. The support rod is fixedly installed on the upper surface of the base plate, the movable plate is rotatably installed on the support rod, and the fixed rod is fixedly connected to the movable plate and rotates synchronously with it. A hoisting positioning position is fixedly provided on the support column, and the hoisting positioning position is in a transmission cooperation with the movable plate. The positioning mechanism includes a clamping plate, and the fixed rod passes through the base plate and is in a transmission connection with the clamping plate.

[0008] Furthermore, the support column, the reciprocating swing mechanism, and the positioning mechanism are combined through mechanical linkage. Specifically, when the U-shaped ring is pulled up and drives the support column to rise, the hoisting positioning drive drives the moving plate to swing. The swing of the moving plate drives the fixed rod to rotate, thereby driving the clamping plate to move inward to clamp the prefabricated component.

[0009] Furthermore, the core technical solution directly converts the vertical lifting force into the horizontal mechanical clamping force, achieving a gravity self-locking function. That is, the greater the lifting load, the greater the clamping force transmitted to the clamping plate through the reciprocating swing mechanism, thereby effectively avoiding the risk of components slipping in the air, and eliminating the need for manual pre-tightening, significantly improving the efficiency of lifting operations.

[0010] Preferably, the hoisting positioning buckle further includes a hollow tube, acupressure posts, and a disassembly assembly; the hollow tube is inserted into the connection between the U-shaped ring and the support post to fix the support post, and the U-shaped ring has movable posts on both sides, with the acupressure posts slidably inserted into the movable posts; the disassembly assembly is located inside the hollow tube and includes a positioning plate, a positioning pin, a positioning block, a spring, and a push rod; the positioning block is located inside the hollow tube and is linked to the acupressure posts, and the positioning pin is fixed to the inner wall of the hollow tube.

[0011] Furthermore, the preferred solution triggers the displacement of internal components by pressing down on the finger pressure column, allowing the positioning block and positioning pin to quickly lock or separate under the action of spring one. This eliminates the need for additional tools to quickly install and remove the hoisting handle, greatly facilitating equipment maintenance and relocation.

[0012] Preferably, the reciprocating swing mechanism further includes a moving bar, and the moving plate has a slot, in which the moving bar is slidably disposed; the cooperation relationship between the moving bar and the moving plate is as follows: when the hoisting positioning and lifting mechanism drives the moving plate to swing, the moving bar slides in the slot; when the moving bar moves to the top of the slot, the moving plate stops swinging, and the support rod provides limiting support for the moving plate.

[0013] Furthermore, by setting the sliding engagement between the moving bar and the slot, the swing angle range of the moving plate is precisely limited, preventing the mechanical structure from jamming or failing due to excessive swing amplitude. At the same time, it provides a clear stop point for the support rod, enhancing the stability of the structure.

[0014] Preferably, the reciprocating rocking mechanism further includes a fixing bar, which is fixedly installed on the base plate; a sliding groove is provided in the fixing bar, and a sliding block is provided in the sliding groove, which is connected to the clamping plate; the sliding block is configured to move along the sliding groove when the fixing rod rotates and drives the clamping plate to move; when the sliding block moves to the top of the sliding groove, the clamping distance of the clamping plate reaches the minimum value.

[0015] Furthermore, by utilizing the grooves and sliding blocks within the fixing strip, the movement trajectory of the clamping plate is strictly regulated, ensuring that the clamping plate always moves along the preset route for opening and closing. At the same time, the minimum clamping distance is limited to prevent excessive compression of components with smaller dimensions.

[0016] Preferably, the clamping plate includes an outer shell and a connecting ring, a second spring, and a second push rod disposed inside the outer shell; the connecting ring is sleeved on the second push rod, the second push rod is driven by the movement of the clamping plate, and the second spring abuts against the connecting ring and the inner wall of the clamping plate.

[0017] Furthermore, a flexible buffer mechanism is introduced at the end of the rigid mechanical transmission. During the clamping process, the second spring is compressed first, thereby converting the rigid impact force into an elastic clamping force, which effectively prevents scratches or chipping on the surface of the precast component caused by hard contact.

[0018] Preferably, the positioning mechanism further includes a pressure column and a spring three; the pressure column is slidably disposed under the bottom plate, and the spring three is disposed between the pressure column and the bottom plate; the pressure column is configured to bear pressure and move upward to compress the spring three when the device presses down to contact the precast component.

[0019] Furthermore, the pressure column and spring form a vertical shock absorption device, which can absorb and release impact energy the moment the lifting device contacts the top surface of the component, thus protecting the bottom plate of the lifting device and preventing damage to the surface of the component.

[0020] Preferably, the positioning mechanism further includes a tapered guide post, which is fixedly disposed on the lower surface of the base plate and located inside the clamping plate.

[0021] Furthermore, by utilizing the conical guide column's conical guiding effect, the lifting device can be quickly inserted into the reserved hole of the precast component, achieving automatic correction and positioning, and reducing the requirements for crane operation accuracy.

[0022] Preferably, the reciprocating rocking mechanism further includes a support plate, which is fixedly connected to the edge of the base plate and configured to provide structural support to the base plate when the clamping plate is driven by the fixed rod.

[0023] Furthermore, the support plate significantly enhances the structural rigidity of the base plate edge, preventing warping and deformation of the base plate under high-load clamping conditions, thus ensuring the durability and reliability of the overall mechanism.

[0024] This utility model has the following beneficial effects: 1. This utility model, by setting up a reciprocating swing mechanism and a hoisting positioning buckle to form a linkage, uses the vertical tension generated during hoisting to drive the swing mechanism to deflect, which is then converted into the rotational torque of the fixed rod to drive the clamping plate to close. This solves the problem that existing precast component hoisting equipment usually relies on manual locking, resulting in low efficiency and safety hazards due to the difficulty in adjusting the clamping force according to the load. It achieves the effect of "locking upon hoisting", and the clamping force is greater the heavier the load, which significantly improves the safety and automation of hoisting operations.

[0025] 2. This utility model solves the problem that traditional rigid lifting devices are prone to causing bumps, scratches or chipping on the surface of precast components during the moment of contact and strong clamping by integrating a horizontal buffer assembly consisting of a connecting ring and a spring inside the clamping plate, and setting a vertical buffer assembly consisting of a pressure column and a spring in the positioning mechanism. It achieves the technical effect of flexible clamping and soft landing, effectively protecting the integrity of the precast components, absorbing impact energy, and extending the service life of the equipment.

[0026] 3. This utility model, by designing a quick-disassembly component including a positioning plate, positioning pin, and finger pressure column inside the hoisting positioning buckle, utilizes the pressing action to trigger the internal spring to rebound and engage or disengage with the positioning pin. This solves the problems of traditional hoisting handles, which are mostly fixed by welding or bolts, resulting in cumbersome assembly and disassembly, large space occupation during transportation and storage, and difficult maintenance. It achieves the technical effect of quick installation and disassembly of the handle without the need for additional tools, greatly facilitating the daily maintenance and relocation of equipment.

[0027] 4. This utility model solves the problems of difficulty in aligning the lifting tools and the reserved holes of the components during hoisting, and the mechanical transmission structure is prone to jamming and failure due to excessive stroke, by setting a conical guide column under the base plate and setting a guide groove and a limiting moving strip in the reciprocating swing mechanism. It achieves the technical effects of assisting automatic correction, fast and accurate positioning, and strictly limiting the mechanical movement trajectory to ensure the stable operation of the structure.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Example: Reference Figures 1 to 4 This utility model provides a precast component hoisting and positioning buckle structure, which aims to solve the technical problems of existing precast component hoisting equipment relying on manual locking, resulting in low efficiency and lack of buffering mechanism, which easily leads to damage to the surface of the component.

[0032] A precast component hoisting and positioning buckle structure includes a base plate 1, a reciprocating swing mechanism 2 and a hoisting positioning buckle 3 disposed on the upper surface of the base plate 1, and a positioning mechanism 4 disposed on the lower surface of the base plate 1. The base plate 1 serves as the basic bearing platform of the overall device, used to install and support various functional components, and to withstand the vertical tension and horizontal clamping reaction force during the hoisting process. The reciprocating swing mechanism 2 is located above the base plate 1, and its function is to convert the vertical hoisting tension into the horizontal mechanical driving force. The hoisting positioning buckle 3 serves as the connecting end of the external crane hook, and its lower part penetrates through the base plate 1 and forms a linkage with the reciprocating swing mechanism 2. The positioning mechanism 4 serves as the execution end that directly contacts the precast component, and is used to achieve clamping, fixing and buffering protection of the component.

[0033] The hoisting positioning buckle 3 includes a vertically arranged support column 32 and a U-shaped ring 31 fixedly connected to the top of the support column 32. The U-shaped ring 31 is used for the crane hook to pass through. The bottom end of the support column 32 moves through the through hole reserved in the base plate 1 and extends into the internal area of ​​the reciprocating swing mechanism 2. A hoisting positioning position 23 is fixedly installed on the outer wall of the support column 32. The hoisting positioning position 23 is a key node for power transmission and is used to output displacement driving force when the support column 32 is lifted under force. The reciprocating swing mechanism 2 includes a support rod 24 fixedly installed on the upper surface of the base plate 1 and a moving plate 26 rotatably connected to the top of the support rod 24. The support rod 24 plays a fixed-point support role, so that the moving plate 26 can reciprocate around the axis of the support rod 24. One side of the moving plate 26 is in contact with or connected to the hoisting positioning position 23. When the hoisting positioning position 23 rises with the support column 32, it directly pushes the moving plate 26 to deflect at an angle.

[0034] In the power transmission link, a fixed rod 25 is fixedly connected to the movable plate 26. The fixed rod 25 rotates synchronously with the movable plate 26, and the bottom end of the fixed rod 25 passes through the base plate 1 and extends to the bottom of the base plate 1 to establish a transmission connection with the clamping plate 41 in the positioning mechanism 4. The rotational torque of the fixed rod 25 directly drives the clamping plate 41 to perform opening and closing actions, thereby converting the swinging motion of the movable plate 26 into the clamping action of the clamping plate 41 on the prefabricated component. In addition, a support plate 21 is fixedly connected to the edge of the base plate 1. The support plate 21 is located on the side of the reciprocating swing mechanism 2 to enhance the overall structural rigidity of the base plate 1, prevent the base plate 1 from deforming during heavy-load hoisting, and provide lateral auxiliary protection for the reciprocating swing mechanism 2 to ensure the stability of the overall structure under stress. The top of the support column 32 is provided with an adapter mounting groove, and the hollow tube 33 is inserted into the mounting groove. The groove is used to connect the U-shaped ring 31 and the support column 32. Movable columns 35 are respectively provided on both sides of the U-shaped ring 31. The acupressure column 34 slides through the movable column 35 and extends downward to the inner cavity of the hollow tube 33. The disassembly assembly 36 is set in the inner space of the hollow tube 33. The disassembly assembly 36 includes a positioning plate 361, a positioning pin 362, a positioning block 37, a spring 38, and a push rod 39. The positioning pin 362 is fixedly set on the inner wall of the hollow tube 33 as a locking base point. The positioning block 37 is fixedly connected to the bottom end of the acupressure column 34 and rises and falls synchronously with the acupressure column 34. The push rod 39 is elastically connected to the positioning plate 361 through the spring 38. The spring 38 is sleeved on the push rod 39 to provide a reset force. The positioning plate 361 is configured to be able to displace and avoid vertical pressure and rebound using the spring force.

[0035] In the assembled or locked state, the operator presses down on the acupressure post 34. The acupressure post 34 moves the positioning block 37 at the bottom downwards. The positioning block 37 contacts and presses against the positioning disc 361. The spring 38 is compressed and drives the push rod 39 to move backward, forcing the positioning disc 361 to move downwards until it touches the positioning pin 362. The positioning disc 361 quickly returns to its original position under the rebound of the spring 38, driving the push rod 39 to push forward, so that the positioning block 37 and the positioning pin 362 form a locking fixation, thereby realizing the self-locking connection of the hoisting handle. In a preferred embodiment, the reciprocating swing mechanism 2 further includes a movable bar 22. A guide groove is formed on the surface of the movable plate 26. The movable bar 22 is slidably installed inside the guide groove, forming a sliding fit between the movable bar 22 and the guide groove. When the hoisting positioning 23 drives the movable plate 26 to swing and deflect, the movable bar 22 undergoes relative displacement along the length direction of the guide groove. When the movable bar 22 slides to the top position of the guide groove, the support rod 24 comes into contact with the movable plate 26, thereby limiting further swinging of the movable plate 26. To ensure the stability of the mechanical transmission, the reciprocating swing mechanism 2 also includes a fixing bar 27. The fixing bar 27 is fixedly installed on the upper surface of the base plate 1 by bolts or welding. The fixing bar 27 has a sliding groove inside, and a sliding block is set in the sliding groove. The sliding block is fixedly connected or linked to the clamping plate 41. When the fixing rod 25 rotates and drives the clamping plate 41 to close inward, the sliding block slides synchronously in the sliding groove of the fixing bar 27. The displacement of the sliding block is limited by the physical stroke end of the sliding groove, thereby precisely controlling the minimum distance when the clamping plate 41 clamps the item. The clamping plate 41 consists of an outer shell and an internal buffer assembly. The internal buffer assembly includes a connecting ring 42, a second spring 43, and a second push rod 44. The connecting ring 42 is sleeved on the outer periphery of the second push rod 44. One end of the second push rod 44 is connected to the fixed rod 25. The second spring 43 abuts against the inner wall of the outer shell of the clamping plate 41. Under clamping conditions, the fixed rod 25 transmits thrust through the second push rod 44, preferentially compressing the second spring 43. The elastic deformation of the second spring 43 drives the outer shell of the clamping plate 41 to fit against the prefabricated component, achieving flexible contact and adaptive clamping. The positioning mechanism 4 is also equipped with a pressure column 45 and a third spring 46. The pressure column 45 slides through the bottom through hole of the base plate 1, and the third spring 46 is located at the top of the pressure column 45 and the internal space of the base plate 1. When the device is placed on the precast component, the pressure column 45 slides upward under pressure and compresses the spring 46. The spring 46 absorbs and releases the vertical impact energy. The positioning mechanism 4 also includes a tapered guide column 47, which is fixedly connected to the center of the lower surface of the base plate 1 and located between the two clamping plates 41. The tapered guide column 47 is inserted into the reserved hole or positioning point of the precast component during the descent of the device to achieve automatic correction and guidance. The reciprocating swing mechanism 2 is also provided with a support plate 21 on the side. The support plate 21 is fixedly connected to the edge of the base plate 1. The support plate 21 is made of high-strength metal and is used to provide auxiliary support when the clamping plate 41 is clamped and the base plate 1 is subjected to heavy load, so as to prevent the edge of the base plate 1 from warping and deforming.

[0036] The implementation principle of this application embodiment is as follows: the prefabricated component hoisting positioning buckle 3 structure is composed of a reciprocating swing mechanism 2 and a hoisting positioning buckle 3 on the upper part of the base plate 1, and a positioning mechanism 4 on the lower part. When the hoisting positioning buckle 3 is pulled up, it drives the mechanical part inside the reciprocating swing mechanism 2 to swing. When the mechanical part inside the reciprocating swing mechanism 2 swings, it drives the positioning mechanism 4 to position it. Then the mechanical part inside the positioning mechanism 4 will clamp the positioned item, thereby moving the item.

[0037] When it is necessary to raise the hoisting positioning buckle 3, insert the hollow tube 33 into the U-shaped ring 31 to fix the support column 32. Then insert the acupressure column 34 into the movable columns 35 on both sides and press it down. At this time, the positioning block 37 in the hollow tube 33 will first collide with the positioning plate 361 in the disassembly component 36. The spring 38 drives the push rod to push backward, and then drives the positioning plate 361 to move down and hit the positioning pin 362. At this time, the positioning plate 361 will quickly return, and the spring 38 drives the push rod 39 forward. At the same time, the positioning block 37 will lock with the positioning pin 362 and fix it.

[0038] When the U-shaped ring 31 moves upward, the support column 32 will drive the hoisting positioning 23 to rise and fall. When the hoisting positioning 23 rises and falls, it will drive the moving plate 26 to swing. At the same time, when the moving bar 22 in the slot of the moving plate 26 moves to the top of the slot, the moving plate 26 stops swinging. Meanwhile, the support rod 24 will support the moving plate 26. When the moving plate 26 moves, it will drive the fixed rod 25 to rotate. When the fixed rod 25 rotates, it will drive the clamping plate 41 to clamp the item and fix the moving plate 26. At the same time, when the fixed rod 25 rotates, the sliding block in the fixed bar 27 will follow the slide groove in the fixed bar 27 and move the clamping plate 41. When the sliding block in the fixed bar 27 moves to the top of the slide groove, it is the minimum value of the item clamped by the clamping plate 41.

[0039] When the clamping plate 41 is driven by the fixing rod 25, the support plate 21 will support the base plate 1. At the same time, the clamping plate 41 will move forward, driving the push rod 44 in the connecting ring 42. Under the action of the spring 43, the item will be clamped. At the same time, the conical guide post 47 will position the item. When it is pressed down, the pressure post 45 will bear the pressure from the item. At the same time, the spring 46 will release the pressure on the pressure post 45.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
