Description

Technical Field

[0001] This utility model belongs to the field of building installation technology, and specifically relates to a building material lifting device for building installation. Background Technology

[0002] Construction and installation refers to the general term for construction, repair, installation, and other engineering operations. Among these, building material lifting devices are indispensable equipment on construction sites. They are mainly used to lift and transport building materials to improve construction efficiency and reduce the labor intensity of workers. When selecting and using these devices, it is necessary to fully consider factors such as construction needs, equipment quality, and safe operating procedures to ensure the smooth progress of construction and the safety of personnel and equipment.

[0003] Announcement No. "CN221093611U" discloses a building material lifting device for construction installation, comprising a base, pulleys fixedly installed at the four corners of the bottom end of the base, a hydraulic cylinder and a support plate installed at the top end of the base, support rods fixedly installed at the four corners of the top end of the base, a placement plate installed at the top end of the hydraulic cylinder, springs fixedly installed at the four corners of the bottom end of the placement plate, a moving groove formed on the inner surface of the placement plate, a pressure plate slidably connected to the inner side of the moving groove, a washer fixedly installed at the bottom end of the pressure plate, and a threaded rod rotatably connected to the top end of the pressure plate. In this utility model, by setting a pressure plate on the lifting device, convenient positioning of building materials is provided, preventing damage or even falling of the edges and corners of the building materials, improving the safety of the lifting device, and allowing the lifting device to hold building materials of different thicknesses, thus increasing the application range of the lifting device.

[0004] Although the aforementioned utility model provides convenient positioning of building materials by setting a pressure plate on the lifting device, preventing damage to the edges or corners of the building materials or even falling off, and improving the safety of the lifting device, it also allows the lifting device to place building materials of different thicknesses, increasing the scope of application of the lifting device. However, during the descent of the placement plate, it can cause the placement plate and the building materials it supports to shake or vibrate violently. This shaking or vibration not only affects the stability of the lifting device, but also has an adverse impact on the surrounding environment and building structure. Moreover, the placement plate may generate a large impact force when descending, which can damage the structure of the lifting device, or even lead to malfunction or accident of the lifting device. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a building material lifting device for building installation, so as to solve the problem that during the descent of the placement plate, the placement plate and the building materials it supports will cause violent shaking or vibration. This shaking or vibration will not only affect the stability of the lifting device, but also have an adverse effect on the surrounding environment and building structure. Moreover, the placement plate may generate a large impact force when it descends. This impact force will damage the structure of the lifting device, and may even lead to the failure or accident of the lifting device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A building material lifting device for construction installation includes a base, a cylinder installed on the upper end of the base, a lifting plate fixedly connected to the telescopic end of the cylinder, positioning columns symmetrically fixedly connected to the upper end of the base near the chamfer, the lifting plate and the positioning columns being slidably connected, limit plates symmetrically fixedly connected to the upper end of the base, buffer plates symmetrically provided on the upper end of the base, buffer components symmetrically installed between the buffer plates and the base, a placement box slidably connected to the upper end of the lifting plate, connecting blocks symmetrically fixedly connected to both ends of the placement box, installation components installed inside the connecting blocks, and fixing blocks symmetrically fixedly connected to the upper end of the lifting plate.

[0008] The buffer assembly includes a buffer seat, a first limiting post, an internal hole, a first buffer spring, and a second limiting post. Buffer seats are symmetrically fixedly connected to the bottom end of the buffer plate and the top end of the base. A first limiting post is fixedly connected to the upper end of the buffer seat on the upper end of the base. An internal hole is formed at the upper end of the first limiting post, and a first buffer spring is fixedly connected to the bottom end of the internal hole. A second limiting post is fixedly connected to the other end of the first buffer spring. The second limiting post is slidably connected to the internal hole. The end of the second limiting post away from the first buffer spring is fixedly connected to one end of the buffer seat at the bottom end of the buffer plate. A second buffer spring is sleeved on the outer side of the first and second limiting posts. The two ends of the second buffer spring are fixedly connected to the opposite ends of the buffer seat. This effectively reduces the impact force generated when the lifting plate descends, making the lifting process smoother. It helps reduce safety hazards caused by vibration and shaking, improves the overall stability of the device, and reduces wear and tear on the lifting device during frequent use, thereby reducing maintenance costs and replacement frequency, and extending the service life of the entire lifting device.

[0009] As a preferred technical solution, positioning blocks are symmetrically fixedly connected to the opposite ends of the limiting plate, and positioning grooves are symmetrically opened at both ends of the lifting plate. The positioning blocks and positioning grooves are slidably connected. The design of the positioning blocks and positioning grooves can ensure that the lifting plate maintains a stable posture during the lifting process and prevent the lifting plate from shaking or tilting.

[0010] As a preferred technical solution, guide wheels are symmetrically rotated at both ends of the lifting plate, and guide grooves are opened at the opposite ends of the limiting plate. The guide wheels and guide grooves are slidably connected. The cooperation between the guide wheels and guide grooves can ensure that the lifting plate moves along a predetermined trajectory during the lifting process, thereby improving the lifting accuracy.

[0011] As a preferred technical solution, the mounting assembly includes a cavity, a return spring, a movable plate, and a locking block. The connecting block has a cavity inside, with a return spring fixedly connected to the bottom of the cavity. A movable plate is fixedly connected to the other end of the return spring, and the movable plate is slidably connected to the cavity. A locking block is fixedly connected to the end of the movable plate away from the return spring. The end of the locking block away from the movable plate extends beyond the upper end of the connecting block, and the end of the locking block near the fixed block is beveled. A connecting groove is formed at one end of the fixed block, and the connecting groove is inserted into the connecting block. A locking groove is formed at the upper end of the connecting groove, and the locking groove is connected to the locking block. The locking block is a snap-fit ​​mechanism, and an unlocking block is slidably connected inside the locking groove. The end of the unlocking block away from the locking block extends out of the upper end of the fixing block. Limiting blocks are symmetrically fixedly connected at both ends of the unlocking block. Limiting grooves are symmetrically opened inside the locking groove. The limiting blocks and limiting grooves are slidably connected, which allows construction personnel to quickly fix the placement box on the lifting plate or remove it from the lifting plate, thereby saving a lot of time and labor costs. Moreover, it allows construction personnel to easily inspect and maintain the placement box, ensuring that the placement box and its connecting parts are in good condition and improving the safety of the overall device.

[0012] As a preferred technical solution, the upper end of the placement box is threaded with an adjusting screw. The bottom end of the adjusting screw extends into the interior of the placement box and is rotatably connected to a pressure plate. The bottom end of the pressure plate is fixedly connected to an anti-slip pad, and the upper end of the adjusting screw is fixedly connected to a torsion block. This can greatly reduce the risk of building materials slipping during lifting and transportation, not only protecting the building materials themselves from damage, but also ensuring the safety of construction personnel and the surrounding environment.

[0013] In summary, the present invention has the following main advantages:

[0014] First, in this utility model, the cylinder is activated to control the lifting plate to descend. When the lifting plate descends, it drives the positioning groove to slide outside the positioning block. At the same time, the lifting plate slides outside the positioning column. The lifting plate descends and presses against the buffer plate. The buffer plate drives the second limiting column to slide inside the built-in hole. At the same time, the second limiting column presses against the first buffer spring, and the first buffer spring is compressed. The buffer seat at the bottom of the buffer plate presses against the buffer seat at the top of the base, and the second buffer spring is compressed. This can effectively reduce the impact force generated by the lifting plate when it descends, making the lifting process more stable. It helps to reduce safety hazards caused by vibration and shaking, improves the stability of the overall device, and reduces the wear of the lifting device in frequent use, thereby reducing maintenance costs and replacement frequency, and extending the service life of the entire lifting device.

[0015] Secondly, in this utility model, the placement box and the lifting plate are combined, allowing the placement box to slide with the lifting plate. The placement box drives the connecting blocks on both sides to insert into the connecting groove at one end of the fixing block. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block, causing the locking block to drive the moving plate to compress the return spring. The locking block retracts into the cavity. Then, when the locking block moves to the locking groove, the return spring resets, the moving plate rebounds, and the locking block pops out. The locking block and the locking groove are locked together. This allows construction personnel to quickly fix the placement box on the lifting plate or remove it from the lifting plate, thus saving a lot of time and labor costs. Moreover, it allows construction personnel to easily inspect and maintain the placement box, ensuring that the placement box and its connecting parts are in good condition and improving the safety of the overall device.

The first limiting post 202 is fixedly connected to the upper end of the buffer seat 201 on the upper end of the base 1. An internal hole 203 is formed at the upper end of the first limiting post 202. The bottom end of the internal hole 203 is fixedly connected to the first buffer spring 204. The other end of the first buffer spring 204 is fixedly connected to the second limiting post 205. The second limiting post 205 is slidably connected to the internal hole 203. The end of the second limiting post 205 away from the first buffer spring 204 is fixedly connected to one end of the buffer seat 201 at the bottom end of the buffer plate 19. Next, a second buffer spring 21 is sleeved on the outer side of the first limiting post 202 and the second limiting post 205. The two ends of the second buffer spring 21 are fixedly connected to the opposite ends of the buffer seat 201. The cylinder 2 is activated to control the lifting plate 3 to descend. When the lifting plate 3 descends, it slides on the outside of the positioning post 4. The lifting plate 3 descends and presses against the buffer plate 19. The buffer plate 19 drives the second limiting post 205 to slide inside the built-in hole 203. At the same time, the second limiting post 205 presses against the first buffer spring 204, and the first buffer spring 204 is compressed. The buffer seat 201 at the bottom of the buffer plate 19 presses against the buffer seat 201 at the top of the base 1, and the second buffer spring 21 is compressed, absorbing and dispersing the impact force generated during descent.

[0024] refer to Figure 2 The limiting plate 5 is symmetrically fixedly connected with positioning blocks 6 at opposite ends. The lifting plate 3 is symmetrically provided with positioning grooves 7 at both ends. The positioning blocks 6 and the positioning grooves 7 are slidably connected. When the lifting plate 3 is raised or lowered, the lifting plate 3 drives the positioning grooves 7 to slide on the outside of the positioning blocks 6.

[0025] refer to Figure 2 The lifting plate 3 is symmetrically connected to guide wheels 8 at both ends, and the limiting plate 5 is provided with guide grooves 9 at opposite ends. The guide wheels 8 and the guide grooves 9 are slidably connected. When the lifting plate 3 is raised or lowered, the lifting plate 3 drives the guide wheels 8 to slide inside the guide grooves 9.

[0026] refer to Figure 4 The mounting assembly 14 includes a cavity 141, a return spring 142, a movable plate 143, and a locking block 144. The connecting block 11 has a cavity 141 inside. A return spring 142 is fixedly connected to the bottom end of the cavity 141. A movable plate 143 is fixedly connected to the other end of the return spring 142. The movable plate 143 is slidably connected to the cavity 141. A locking block 144 is fixedly connected to the end of the movable plate 143 away from the return spring 142. The end of the locking block 144 away from the movable plate 143 extends beyond the upper end of the connecting block 11. The end of the locking block 144 near the fixed block 12 is sloped. A connecting groove 13 is formed at one end of the fixed block 12. The connecting groove 13 is inserted into the connecting block 11. An opening is formed at the upper end of the connecting groove 13. There is a locking groove 15, which is engaged with the locking block 144. The placement box 10 and the lifting plate 3 are combined, and the placement box 10 and the lifting plate 3 slide. The placement box 10 drives the connecting blocks 11 on both sides to be inserted into the connecting groove 13 at one end of the fixing block 12. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 144, so that the locking block 144 drives the moving plate 143 to compress the return spring 142. The locking block 144 retracts into the cavity 141. Then, when the locking block 144 moves to the locking groove 15, the return spring 142 returns to its original position, and the moving plate 143 rebounds, causing the locking block 144 to pop out. The locking block 144 is engaged and fixed with the locking groove 15, completing the installation of the placement box 10.

[0027] refer to Figure 4 An unlocking block 16 is slidably connected inside the locking groove 15. The end of the unlocking block 16 away from the locking block 144 extends out of the upper end of the fixing block 12. Limiting blocks 17 are symmetrically fixedly connected at both ends of the unlocking block 16. Limiting grooves 18 are symmetrically opened inside the locking groove 15. The limiting blocks 17 and the limiting grooves 18 are slidably connected. Pushing the unlocking block 16 causes it to slide inside the locking groove 15. At the same time, the limiting blocks 17 slide inside the limiting grooves 18. The unlocking block 16 pushes the locking block 144, causing the locking block 144 to drive the moving plate 143 to compress the reset spring 142. The locking block 144 retracts into the cavity 141. The locking block 144 and the locking groove 15 are no longer engaged. Then, the placement box 10 is pulled outward. The connecting block 11 and the connecting groove 13 are no longer engaged, completing the disassembly of the placement box 10.

[0028] refer to Figure 1The upper end of the placement box 10 is threaded with an adjusting screw 22. The bottom end of the adjusting screw 22 extends into the placement box 10 and is rotatably connected to a pressure plate 24. The bottom end of the pressure plate 24 is fixedly connected to an anti-slip pad 25. The upper end of the adjusting screw 22 is fixedly connected to a torsion block 23. The building materials are placed inside the placement box 10, and then the torsion block 23 is rotated. The torsion block 23 drives the adjusting screw 22 to rotate, and the adjusting screw 22 drives the pressure plate 24 to descend. The pressure plate 24 clamps and fixes the building materials.

[0029] Operating principle and advantages: First, the placement box 10 and the lifting plate 3 are combined, allowing the placement box 10 and the lifting plate 3 to slide. The placement box 10 drives the connecting blocks 11 on both sides to insert into the connecting groove 13 at one end of the fixed block 12. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 144, causing the locking block 144 to drive the moving plate 143 to compress the return spring 142. The locking block 144 retracts into the cavity 141. Then, when the locking block 144 moves to the locking groove 15, the return spring 142 resets, and the moving plate 143 rebounds, causing the locking block 144 to spring back. The locking block 144 is engaged with the locking groove 15 to complete the installation of the placement box 10. Then, the building materials are placed inside the placement box 10. Then, the torsion block 23 is rotated, which drives the adjusting screw 22 to rotate. The adjusting screw 22 drives the pressure plate 24 to descend, and the pressure plate 24 clamps and fixes the building materials. Finally, the cylinder 2 is started to control the cylinder 2 to push the lifting plate 3 and the placement box 10 above to rise. When the lifting plate 3 rises and falls, the lifting plate 3 drives the positioning groove 7 to slide outside the positioning block 6, and the lifting plate 3 drives the guide wheel 8 to slide inside the guide groove 9.

[0030] This invention can effectively reduce the impact force generated when the lifting plate 3 descends, making the lifting process more stable. It helps to reduce safety hazards caused by vibration and shaking, improves the stability of the overall device, and reduces the wear and tear of the lifting device during frequent use, thereby reducing maintenance costs and replacement frequency, and extending the service life of the entire lifting device.
