Description

Technical Field

[0001] The present invention relates to a steel plate lifting hanger, and particularly to a steel plate lifting hanger for building construction. Background Art

[0002] During the process of building construction, steel plates are often needed. Before the use of steel plates, they usually need to be transported to the place of use. During transportation, a steel plate lifting hanger is required to lift and transport the steel plates.

[0003] There are several existing ways to lift steel plates:

[0004] One way is to place the steel plate on a plane and then clamp and lift the steel plate by using a clamping method. For example, in the patent with the authorized patent publication number CN109052155B, a steel plate lifting device for building construction disclosed therein. However, when using the above method, the steel plate is clamped by a lifting hook and then lifted. What is achieved is to lift by means of clamping, and it is difficult to support the bottom of the steel plate. The steel plate is easy to fall off from the lifting hook, which has a certain danger.

[0005] Another way is to first place a placing plate on a plane, then place the steel plate on the placing plate, and lift the placing plate to lift the steel plate. For example, in the patent with the authorized patent publication number CN110902567B, a steel plate lifting device with high safety for building construction disclosed therein. When operating the above method, although the bottom of the steel plate can be lifted, it is necessary to manually carry the steel plate onto the placing plate, and the operation process is relatively cumbersome and labor-consuming. Summary of the Invention

[0006] In order to overcome the shortcomings that when lifting by using a clamping method, the steel plate is easy to fall off and has a certain danger, and when lifting by using a placing plate to support the steel plate, manual handling is required during operation, the purpose of the present invention is to provide a steel plate lifting hanger for building construction that can support the bottom of the steel plate during lifting without manual handling.

[0007] The technical implementation solution of the present invention is as follows: A steel plate lifting hanger for building construction includes an installation frame, a winch, a lifting plate, a moving component, a supporting plate, a clamping component, an anti-slip component, and a transmission mechanism. There are two installation frames. A moving component is arranged between the two installation frames. A winch is installed on the moving component. A lifting plate is connected to the steel wire rope of the winch. Starting the winch is used to control the lifting and lowering of the lifting plate. A clamping component for clamping the steel plate is arranged on the lifting plate. An anti-slip component for preventing the steel plate from slipping is arranged on the clamping component. A transmission mechanism is arranged on the anti-slip component. A supporting plate is arranged on the transmission mechanism. The transmission mechanism is used to drive the supporting plate to rotate, and the supporting plate rotates to support the bottom of the steel plate to prevent the steel plate from falling.

[0008] More preferably, the moving component includes an electric slide rail and a sliding seat. An electric slide rail is installed between the upper parts of the two mounting brackets. A sliding seat is arranged on the electric slide rail, and the winch is installed at the bottom of the sliding seat.

[0009] More preferably, the clamping component includes a double-shaft motor, a threaded rod, and clamping plates. At least one double-shaft motor is installed on the top of the lifting plate. Threaded rods are connected to both output shafts of the double-shaft motor. Clamping plates are connected to both threaded rods through threads. The two clamping plates can slide on both sides of the lifting plate respectively. The threaded rods rotate to make the two clamping plates approach each other and clamp the steel plate.

[0010] More preferably, the anti-slip component includes a rubber plate and a first elastic member. Rubber plates are slidably connected to both clamping plates, and a first elastic member is connected between the rubber plate and the clamping plate.

[0011] More preferably, the transmission mechanism includes a rack frame, a plug rod, a second elastic member, and a gear. A rack frame is slidably connected to the clamping plate. The rack frame is connected to the rubber plate. Plug rods are movably connected to both sides of the clamping plate. Gears are slidably connected to the plug rods. The gears are rotatably connected to the clamping plate. When the rack frame moves, it drives the gears to rotate, so as to drive the plug rods to rotate. A support plate is rotatably connected to the bottom of the plug rod, and a second elastic member is connected between the support plate and the plug rod, so that the second elastic member drives the support plate to rotate through elasticity.

[0012] More preferably, one side of the lower part of the clamping plate close to the support plate is provided with an inclined surface, so that the support plate can be guided by the inclined surface of the clamping plate when rotating, to prevent the clamping plate from blocking the rotation of the support plate.

[0013] More preferably, a limiting mechanism is further included. The limiting mechanism includes a guiding frame, a fixed limiting rod, a swinging limiting rod, a third elastic member, and a sliding push plate. Guiding frames are connected to both sides of the sliding seat. Fixed limiting rods for limiting the steel plate are slidably connected to both sides of the guiding frame. A swinging limiting rod is rotatably connected to the fixed limiting rod. The swinging limiting rod swings downward to limit the steel plate. A third elastic member is connected between the swinging limiting rod and the fixed limiting rod to drive the swinging limiting rod to reset through elasticity. Sliding push plates are connected to both sides of the clamping plate, and the sliding push plates can slide on the fixed limiting rod and the swinging limiting rod to squeeze the swinging limiting rod to swing.

[0014] More preferably, a pressing component is further included. The pressing component includes a pressing cylinder and a pressing block. Pressing cylinders are installed at the four corners of the lifting plate. A pressing block is connected to the telescopic rod of the pressing cylinder. The pressing block moves up and down to press the steel plate, and the pressing block is slidably matched with the clamping plate.

[0015] The beneficial effects are as follows: 1. When the clamping plate in the present invention clamps and lifts the steel plate, the supporting plate can swing to support the steel plate to prevent the steel plate from falling off. At the same time, there is no need for manual handling of the steel plate to the top of the supporting plate, which is more convenient in operation and saves manpower consumption.

[0016] 2. When the present invention lifts the steel plate, it can limit the position of the steel plate through the fixed limiting rod and the swinging limiting rod to prevent the steel plate from shifting.

[0017] 3. The present invention can press the steel plate through the pressing block to improve the stability of the steel plate when it is lifted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] A steel plate lifting frame for construction, such as Figures 1-8 As shown, it includes a mounting frame 1, a moving component, a winch 4, a lifting plate 41, a support plate 8, a clamping component 5, an anti-skid component 6 and a transmission mechanism 7. The mounting frame 1 is set up in two, and a moving component is arranged between the two mounting frames 1. The winch 4 is installed on the moving component. The lifting plate 41 is connected to the wire rope of the winch 4. The winch 4 is started to control the lifting and lowering of the lifting plate 41. The lifting plate 41 is provided with a clamping component 5 for clamping the steel plate. The clamping component 5 is provided with an anti-skid component 6 for preventing the steel plate from slipping. The anti-skid component 6 is provided with a transmission mechanism 7. The transmission mechanism 7 is provided with a support plate 8. The transmission mechanism 7 is used to drive the support plate 8 to rotate. The support plate 8 rotates to support the bottom of the steel plate to prevent the steel plate from falling.

[0035] like Figure 1 As shown, the moving assembly includes an electric slide rail 2 and a sliding seat 3. The electric slide rail 2 is installed between the upper parts of the two mounting frames 1. The sliding seat 3 is arranged on the electric slide rail 2. The winch 4 is installed at the bottom of the sliding seat 3.

[0036] like Figure 3As shown, the clamping assembly 5 includes a biaxial motor 51, a threaded rod 52, and a clamping plate 53. The biaxial motors 51 are installed on the front and rear sides of the top of the lifting plate 41. The output shafts on the left and right sides of the biaxial motor 51 are both connected to the threaded rod 52. The two threaded rods 52 on the left and right sides are both threadedly connected to the clamping plate 53. The clamping plates 53 on the left and right sides can slide on the left and right sides of the lifting plate 41 respectively. The threaded rod 52 rotates to make the two clamping plates 53 approach each other and clamp the steel plate.

[0037] As Figures 4-5 shown, the anti-slip assembly 6 includes a rubber plate 61 and a first elastic member 62. The rubber plates 61 are slidably connected to both clamping plates 53. A first elastic member 62 is connected between the rubber plate 61 and the clamping plate 53.

[0038] As Figures 6-8 shown, the transmission mechanism 7 includes a rack frame 71, a plug rod 72, a second elastic member 73, and a gear 74. The rack frames 71 are slidably connected to the mutually remote sides of both clamping plates 53. The rack frame 71 is connected to the rubber plate 61. The plug rods 72 are movably connected to the front and rear sides of the clamping plate 53. The gear 74 is slidably connected to the plug rod 72. The gear 74 is rotatably connected to the clamping plate 53. When the rack frame 71 moves, it drives the gear 74 to rotate, so as to drive the plug rod 72 to rotate. The support plate 8 is rotatably connected to the bottom of the plug rod 72. A second elastic member 73 is connected between the support plate 8 and the plug rod 72, so that the second elastic member 73 drives the support plate 8 to rotate through elasticity. The side of the lower part of the clamping plate 53 close to the support plate 8 is provided with an inclined surface, so that the support plate 8 can be guided by the inclined surface of the clamping plate 53 during rotation to prevent the clamping plate 53 from blocking the rotation of the support plate 8.

[0039] When the lifting frame is needed to lift the steel plate, the lifting frame can be transported to the place where the lifting is required, and the steel plate is placed on the placement plane, and the clamping plate 53 is located above the front and rear sides of the steel plate. Then, the winch 4 is started to loosen the rope to move the lifting plate 41 downward, and the lifting plate 41 moves downward to drive the clamping plate 53 to move downward. When the clamping plate 53 moves downward, it will drive the insertion rod 72 and the supporting plate 8 to move downward together. When the clamping plate 53 moves to the front and rear sides of the steel plate to be clamped, the supporting plate 8 also moves downward to contact with the placement plane. At this time, the clamping plate 53 continues to move upward. The lower movable support plate 8 does not move, so that the insertion rod 72 extends out of the clamping plate 53, and then the dual-axis motor 51 is started to drive the threaded rod 52 to drive the clamping plates 53 on both sides to approach each other. When the clamping plates 53 on both sides approach each other, they will drive the rubber plates 61 on both sides to approach each other, so that the rubber plates 61 are in contact with the steel plate, and then the clamping plates 53 on both sides continue to approach each other. At this time, the rubber plates 61 do not move, and the clamping plates 53 continue to be in a moving state, so that the first elastic member 62 is stretched to apply pressure to the rubber plates 61, and at the same time, the clamping plates 53 also exert pressure on the rubber plates 61. The rubber plate 61 clamps the steel plate to prevent it from slipping. When the clamping plate 53 moves, it also drives the plug rod 72, the gear 74, the second elastic member 73 and the support plate 8 to move together. When the gear 74 moves, it drives the plug rod 72 to rotate through the rack frame 71. At this time, since the support plate 8 is against the placement plane, the support plate 8 will not rotate. The second elastic member 73 is compressed. After the rubber plate 61 clamps the steel plate, the winch 4 can be started to reel in the lifting plate 41, thereby lifting the steel plate through the clamping plate 53. , the pallet 8 is no longer supported by the placement plane, and under the action of gravity, the pallet 8 and the insertion rod 72 move downward until the insertion rod 72 moves to be supported by the clamping plate 53, and at the same time, under the action of the second elastic member 73, the pallet 8 can be rotated to the bottom of the steel plate, so that the pallet 8 supports the bottom of the steel plate to prevent the steel plate from falling off. In this way, the device can be used to lift the steel plate, and when lifting, the pallet 8 can automatically support the steel plate to prevent the steel plate from falling off. When transportation is needed, the electric slide rail 2 can be used to drive the sliding seat 3 to move back and forth for transportation.

[0040] Example 2

[0041] On the basis of Example 1, Figure 1 , Figure 9 , Figure 10 and Figure 11As shown, it further includes a limiting mechanism 9. The limiting mechanism 9 includes a guiding frame 91, a fixed limiting rod 92, a swinging limiting rod 93, a third elastic member 94, and a sliding push plate 95. Guiding frames 91 are connected to both the front and rear sides of the sliding seat 3. Fixed limiting rods 92 for limiting the steel plate are slidably connected to both the left and right sides of the guiding frame 91. A swinging limiting rod 93 is rotatably connected to the lower part of the fixed limiting rod 92. The swinging limiting rod 93 swings downward to limit the steel plate. A third elastic member 94 is connected between the swinging limiting rod 93 and the fixed limiting rod 92 to drive the swinging limiting rod 93 to reset elastically. Sliding push plates 95 are connected to both sides of the clamping plate 53. The sliding push plates 95 can slide on the fixed limiting rod 92 and the swinging limiting rod 93 to squeeze the swinging limiting rod 93 to swing.

[0042] When the clamping plate 53 moves downward, it will drive the sliding push plate 95 to move downward. When the sliding push plate 95 moves downward, it will squeeze the swinging limiting rod 93 to swing by 90 degrees, and the third elastic member 94 is compressed. When the steel plate is lifted, the fixed limiting rod 92 and the swinging limiting rod 93 can limit the steel plate to prevent the steel plate from displacing. During the clamping process, the movement of the clamping plate 53 will drive the swinging limiting rod 93 and the fixed limiting rod 92 to move together through the sliding push plate 95, so that the swinging limiting rod 93 and the fixed limiting rod 92 approach the steel plate. In this way, the steel plate can be limited when it is lifted.

[0043] As Figure 2 、 Figure 12 and Figure 13 shown, it further includes a pressing assembly 10. The pressing assembly 10 includes a pressing cylinder 101 and a pressing block 102. Pressing cylinders 101 are installed at the four corners of the lifting plate 41. A pressing block 102 is connected to the telescopic rod of the pressing cylinder 101. The pressing block 102 moves up and down to press the steel plate, and the pressing block 102 is slidably matched with the clamping plate 53.

[0044] When the supporting plate 8 supports the steel plate, the pressing cylinder 101 can be started to drive the pressing block 102 to move downward to press the steel plate, so as to achieve the effect of pressing the steel plate, thereby improving the stability when the steel plate is lifted.

[0045] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, and the scope of protection is defined by the content of the claims.
