Description

Technical Field

[0001] This utility model relates to the field of sheet metal hoisting technology, and in particular to a sheet metal hoisting device for building construction. Background Technology

[0002] In the construction process of buildings, the hoisting and transportation of building panels is a crucial step that directly affects the construction progress, safety, and quality. With the rapid development of the modern construction industry, the scale of buildings is constantly expanding, and the construction cycle is gradually shortening, which places higher demands on the efficiency, stability, and adaptability of building panel hoisting and transportation.

[0003] Currently, the most common methods for hoisting sheet metal in building construction rely on traditional cranes in conjunction with slings, wire ropes, or simple clamps. However, these traditional methods have the following problems:

[0004] The wire binding method requires personnel to bind and secure the materials each time they are hoisted, and the hoisting ropes need to be untied when unloading. Similarly, the clamp method requires tightening and loosening the clamps to pick up and put down the boards, which is inconvenient and affects the hoisting efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a hoisting device for building construction panels, which effectively solves the deficiencies of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a hoisting device for building construction materials, including a lifting plate. The top surface of the lifting plate has several guide grooves. Guide rods are fixedly connected to the center of the inner walls of each of the guide grooves. Sliding seats are slidably connected to both sides of each guide rod, and the sliding seats are slidably connected to the inner walls of the guide grooves. Clamping columns are fixedly connected to the center of the top surfaces of each of the sliding seats. Pulling cables are fixedly connected to the facing sides of the sliding seats on both sides of the inner walls of the guide grooves. Pulling cables on corresponding sliding seats are staggered. Drive shafts are rotatably connected to both edges of the lifting plate. Several guide pulleys are fixedly connected to the outer walls of both drive shafts. The pulling cables are slidably connected to the guide pulleys. Parallel pull plates are fixedly connected to the ends of the pulling cables on both sides away from the sliding seats. Lifting lugs are fixedly connected to both sides of the top surfaces of the two parallel pull plates. Thrust springs are provided between corresponding sliding seats.

[0007] Preferably, in any of the above embodiments, the thrust spring is sleeved on the outside of the guide bar, the length of the thrust spring after reset is adapted to the length of the guide bar, and the top of the thrust spring is completely inside the guide groove.

[0008] The technical effect achieved by the above solution is that the sliding seats on both sides are pushed apart by the thrust spring, thereby releasing the clamp and loosening the plate. At the same time, the thrust spring is prevented from protruding out of the guide groove, thus preventing the plate from interfering with the thrust spring.

[0009] Preferably, in any of the above embodiments, support plates are fixedly connected to the edges of both sides of the bottom surface of the lifting plate, the bottom of the two support plates is lower than the bottom of the sliding seat, and the length of the two support plates is adapted to the length of the lifting plate.

[0010] The technical effect achieved by adopting the above solution is that the bottom of the sliding seat can be supported by the solution to prevent it from contacting the ground, so as to pull the sliding.

[0011] Preferably, in any of the above schemes, guide posts are fixedly connected to the middle of both sides of the top surface of the two support plates, and the two parallel pull plates are slidably connected to the two guide posts on both sides, and the length of the guide post is greater than the length of the guide groove.

[0012] The technical effect achieved by adopting the above solution is that the parallel pull plate is guided by the guide column, so that it can be pulled vertically up and down, preventing tilting and preventing the problem of unbalanced force and overturning.

[0013] Preferably, in any of the above schemes, the top of each of the two support plates is provided with a plurality of through holes, and the plurality of pulling steel cables respectively pass through the plurality of through holes to exit the support plates.

[0014] The technical effect achieved by adopting the above solution is that it allows the pulling steel cable to be effectively threaded through, reducing friction.

[0015] Preferably, one side of each of the two corresponding bottom surfaces of the sliding seats is provided with a connecting protrusion, the connecting protrusions of the two corresponding bottom surfaces of the sliding seats are staggered, the end of the pulling steel cable is fixedly connected to the connecting protrusion, and the width of the connecting protrusion is half the width of the bottom surface of the sliding seat.

[0016] The technical effect achieved by adopting the above solution is that it can prevent friction between the staggered pulling steel cables and the sliding seat when they slide, thereby improving the service life of the pulling steel cables.

[0017] This utility model has the following advantages:

[0018] 1. This panel hoisting device for building construction places the panel on the top center of the support plate. The crane hook then lifts two parallel pull plates upwards, causing the lateral pull cables to pull relative to each other. This pulls several sliding seats on both sides, allowing them to clamp together. The panel's weight automatically clamps the sides, facilitating panel fixation. After hoisting to the desired position, the support plate is lowered, restoring the support plate to ground support. The pull cables lose tension, and a thrust spring pushes the sliding seats apart, releasing the clamps and allowing for easy loading and unloading of the panel.

[0019] 2. The hoisting device for building construction panels uses guide columns to guide the parallel pull plates, enabling them to be pulled vertically up and down, preventing tilting and overturning due to unbalanced forces. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0025] like Figures 1 to 3As shown, a hoisting device for building construction materials includes a lifting plate 1. The top surface of the lifting plate 1 has several guide grooves 2. Guide rods 3 are fixedly connected to the center of the inner walls of each guide groove 2. Sliding seats 4 are slidably connected to both sides of each guide rod 3, and the sliding seats 4 are slidably connected to the inner walls of the guide grooves 2. Clamping posts 5 are fixedly connected to the center of the top surface of each sliding seat 4. Pulling steel cables 13 are fixedly connected to the facing sides of the sliding seats 4 on both sides of the inner walls of the guide grooves 2. The pulling steel cables 13 on the two sliding seats 4 are arranged in an interlaced manner. The two sides of the lifting plate 1 are rotatably connected to the drive shaft 11. The outer walls of the two drive shafts 11 are fixedly connected to several guide pulleys 12. The pulling steel cables 13 are slidably connected to the several guide pulleys 12 respectively. The ends of the several pulling steel cables 13 on both sides away from the sliding seats 4 are fixedly connected to the parallel pull plates 9. The top surfaces of the two parallel pull plates 9 are fixedly connected to the lifting lugs 10. The corresponding two sliding seats 4 are provided with thrust springs 6.

[0026] As an optional technical solution of this utility model, the thrust spring 6 is sleeved on the outside of the guide bar 3. The length of the thrust spring 6 after reset is adapted to the length of the guide bar 3. The top of the thrust spring 6 is completely inside the guide groove 2. By pushing the thrust spring 6, the sliding seats 4 on both sides are pushed apart, thereby releasing the clamping and loosening the plate. At the same time, it prevents the thrust spring 6 from protruding out of the guide groove 2 and prevents the plate from interfering with the thrust spring 6.

[0027] As an optional technical solution of this utility model, support plates 7 are fixedly connected to the edges of both sides of the bottom surface of the lifting plate 1. The bottom of the two support plates 7 is lower than the bottom of the sliding seat 4. The length of the two support plates 7 is adapted to the length of the lifting plate 1, so that the bottom of the sliding seat 4 is supported to prevent it from contacting the ground, so as to pull and slide.

[0028] As an optional technical solution of this utility model, guide posts 8 are fixedly connected to the middle of both sides of the top surface of the two support plates 7. The two parallel pull plates 9 are slidably connected to the two guide posts 8 on both sides. The length of the guide post 8 is greater than the length of the guide groove 2. The guide post 8 guides the parallel pull plates 9 so that they can be pulled vertically up and down to prevent tilting and prevent the problem of unbalanced force and overturning.

[0029] As an optional technical solution of this utility model, several through holes 14 are provided on the top of the surfaces of the two support plates 7, and several pulling steel cables 13 pass through the support plates 7 through the several through holes 14, so that the pulling steel cables 13 can pass through effectively and reduce friction.

[0030] As an optional technical solution of this utility model, a connecting protrusion is provided on one side of the bottom surface of each of the two corresponding sliding seats 4. The connecting protrusions on the bottom surfaces of the two corresponding sliding seats 4 are staggered. The end of the pulling steel cable 13 is fixedly connected to the connecting protrusion. The width of the connecting protrusion is half the width of the bottom surface of the sliding seat 4, thereby preventing friction between the staggered pulling steel cable 13 and the sliding seat 4 when it is pulled and slid, and improving the service life of the pulling steel cable 13.

[0031] The following steps are required when using this hoisting device for transporting building construction materials:

[0032] 1) Place the board in the center of the top surface of the support board 1;

[0033] 2) The two parallel pull plates 9 are lifted by the crane hook and pulled upward, so that the left and right pull steel cables 13 are pulled relative to each other, and then the several sliding seats 4 on both sides are pulled to the left and right, so that the several sliding seats 4 on both sides can come closer to each other and clamp together, so that the sides of the inserted plate are clamped.

[0034] 3) After hoisting to the position, lower the lifting plate 1 so that the support plate 7 supports the ground. Then, pull the steel cable 13 to lose tension. Through the push spring 6, push the sliding seats 4 on both sides apart, thereby releasing the clamp and loosening the plate, which facilitates the loading and unloading of the plate.

[0035] In summary, after the sheet material is placed on the top center of the lifting plate 1, the two parallel pull plates 9 are lifted upwards by the crane hook, causing the left and right pulling steel cables 13 to pull relative to each other, thereby pulling several sliding seats 4 on both sides. This allows the sliding seats 4 on both sides to come closer together and clamp, ensuring that the sides of the placed sheet material are clamped. Due to the weight of the sheet material itself, the clamping columns 5 on both sides automatically clamp left and right, facilitating the fixation of the sheet material. After being hoisted to the position, the lifting plate 1 is lowered, and after the support plate 7 is supported by the ground, the pulling steel cables 13 lose tension. Through the push spring 6, the sliding seats 4 on both sides are pushed apart, thereby releasing the clamp and facilitating the loading and unloading of the sheet material. The guide column 8 guides the parallel pull plates 9, enabling them to move vertically up and down, preventing tilting and the problem of unbalanced force causing overturning.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
