Description

Technical Field

[0001] This application relates to the field of material hoisting technology, specifically to a material hoisting device. Background Technology

[0002] A material lifting device is a fixed mechanical conveying equipment, mainly suitable for the vertical lifting of materials, facilitating the upward lifting of materials in construction projects.

[0003] An existing patent (publication number: CN210176365U) discloses a material lifting device, relating to the field of construction equipment technology. The material lifting device includes guide columns, a cage, and a traction steel rope. The guide columns are placed vertically to the ground, with a connecting rod vertically and fixedly connected to the top of each guide column. The cage is positioned among several guide columns and is slidably connected to them. A pulley is fixedly installed on the side of the connecting rod closest to the cage. One end of the traction steel rope passes over the pulley and is fixedly connected to the top of the cage. The cage moves vertically by the traction of the steel rope. Fixing components are fixedly connected to the guide columns on the side furthest from the cage, and the lifting device is secured by these fixing components. This technical solution allows the guide columns to be stably connected to the wall, thereby fixing the entire lifting device to the wall. This prevents the lifting device from tilting or falling due to the increased center of gravity during material lifting, enhancing the device's stability.

[0004] The above solution cannot support the cage when it is stopped at a high position to retrieve materials, and only relies on the lifting rope to pull and fix the cage, which affects the stability and safety of the cage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a material lifting device that can support the bottom of the cage when the cage stops at a high position to retrieve materials, thereby preventing the cage from falling due to rope breakage and improving the stability and safety of the cage. This solves the problem that when the cage stops at a high position to retrieve materials, it is impossible to support the cage, and the cage is only pulled and fixed by the rope, which affects the stability and safety of the cage.

[0006] To achieve the aforementioned goal of supporting the bottom of the hoist cage when it stops at a high position to retrieve materials, preventing the cage from falling due to rope breakage, and improving the stability and safety of the hoist cage, this application provides the following technical solution: A material lifting device, comprising two support columns, with a support crossbar at the top of each support column, and a winding roller rotatably mounted at the bottom of each support crossbar via a connecting frame. One end of the winding roller is connected to the output end of a motor, and the top of the motor is fixed to the bottom of the support crossbar via a fixing block. A suspension rope is provided on the outer surface of the middle part of the roller. One end of the suspension rope is set at the top of the cage. A slider is provided on one side of the cage through a fixing block. The outer surface of the middle part of the slider is slidably set in the inner wall of the middle part of the support column. Multiple limiting plates are arranged in an array on one side of the inner wall of the support column. A limiting groove is formed between two adjacent limiting plates. A limiting block is inserted into the limiting groove. A push rod is provided at one end of the limiting block. The push rod is slidably set in the inner wall of the limiting frame. The top of the limiting frame is set at the bottom of the cage through a fixing block.

[0007] The above solution uses a push rod to push the limiting block into the limiting groove between two adjacent limiting plates, so that the limiting block and the limiting groove fix the position of the cage. This achieves the effect of supporting the bottom of the cage when the cage stops at a high place to retrieve materials, preventing the cage from falling due to rope breakage, and improving the stability and safety of the cage.

[0008] Furthermore, the top cross-section of the slider is T-shaped, and the shape of the outer surface of the middle part of the slider is adapted to the shape of the inner wall of the middle part of the support rod.

[0009] The above solution, by using a T-shaped slider in conjunction with the support poles, can improve the stability of the cage when it moves between the two support poles.

[0010] Furthermore, there are two push rods, one end of each push rod is provided with two limiting blocks, and the other end of each push rod is hinged to two swing rods by two hinge frames. One end of each swing rod is hinged to both ends of one side of the connecting plate by two hinge frames.

[0011] With the above scheme, the movement of the connecting plate causes the two swing rods to move the two push rods, which in turn cause the two push rods to drive the two limit blocks to insert into the limit grooves inside the two support uprights.

[0012] Furthermore, the cage is equipped with four support feet at the four corners of its bottom.

[0013] The above solution provides support for the hoisting cage and increases its height above the ground, preventing damage to the bottom components when the cage is on the ground.

[0014] Furthermore, the inner wall of the middle part of the connecting plate is slidably disposed on the outer surface of the middle part of the limiting rod, and the two ends of the limiting rod are disposed at the bottom of the cage through fixing plates, and one end of the limiting rod has a quadrilateral cross section.

[0015] By using the above method, the angle of movement of the connecting plate can be fixed by sliding the inner wall of the middle part of the connecting plate on the outer surface of the middle part of the limiting rod, thereby improving the stability of the connecting plate when it moves.

[0016] Furthermore, a fixing ring is provided on the outer surface of one end of the limiting rod, and a spring is provided on one side of the fixing ring, with one end of the spring located on one side of the connecting plate.

[0017] With the above scheme, a thrust can be applied to the connecting plate by setting the spring, which can push the connecting plate to reset, thereby causing the push rod to pull the limit block out of the limit groove, causing the limit block to reset, so that the cage can resume its raising or lowering operation.

[0018] Furthermore, a guardrail is hinged to one side of the cage via a hinge frame, and a protective plate is hinged to the other side of the cage via a hinge frame. Both the guardrail and the protective plate are equipped with positioning locks that are compatible with both sides of the cage.

[0019] With the above solution, opening the protective railing allows for easy loading of goods into the cage, while closing the railing protects the goods inside the cage. The protective plate works in conjunction with the railing to protect the goods inside the cage. When the protective plate is flipped open, it is laid in the gap between the cage and the floor, facilitating the transport of goods from the cage to the designated construction site on the floor, thus improving the safety of goods handling.

[0020] Furthermore, a pusher is provided on one side of the protective plate, one end of which is slidably connected to the outer surface of one side of the pusher plate, and the other side of the pusher plate is provided on one side of the connecting plate by a fixing rod.

[0021] With the above solution, flipping open the protective plate can cause the pusher to swing, allowing one end of the pusher to slide on the outer surface of the pusher plate. This allows the pusher plate to move the connecting plate, and when the protective plate is opened to move the goods in the cage, the limit block can be automatically inserted into the limit groove to fix the position of the cage.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This material lifting device uses a push rod to push a limiting block into a limiting groove between two adjacent limiting plates. The limiting block, in conjunction with the limiting groove, fixes the position of the cage, thus supporting the bottom of the cage when the cage stops at a high position to retrieve materials. This prevents the cage from falling due to rope breakage, thereby improving the stability and safety of the cage. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 3 and Figure 4This embodiment of a material lifting device includes two supporting uprights 1, with supporting crossbars 2 at the top of the two supporting uprights 1. A winding roller 3 is rotatably mounted on the bottom of the supporting crossbars 2 via a connecting frame. One end of the winding roller 3 is connected to the output end of a motor 4 via a rotating shaft. The top of the motor 4 is mounted on the bottom of the supporting crossbar 2 via a fixing block. A lifting rope 5 is mounted on the outer surface of the middle part of the winding roller 3. One end of the lifting rope 5 is mounted on the top of a cage 6. A slider 7 is mounted on one side of the cage 6 via a fixing block. The outer surface of the middle part of the slider 7 is slidably mounted within the inner wall of the middle part of the supporting uprights 1. Multiple limiting plates 8 are arrayed on one side of the inner wall of the supporting uprights 1. A limiting groove 21 is formed between two adjacent limiting plates 8. A limiting block 9 is inserted into the limiting groove 21. A push rod 10 is mounted on one end of the limiting block 9. The push rod 10 is slidably mounted within the inner wall of a limiting frame 14. The top of the limiting frame 14 is mounted on the bottom of the cage 6 via a fixing block.

[0033] Please see Figure 3 , Figure 4 and Figure 5 The top cross-section of the slider 7 is T-shaped, and the shape of the outer surface of the middle part of the slider 7 is adapted to the shape of the inner wall of the middle part of the support column 1. The T-shaped slider 7 can work with the support column 1 to improve the stability of the cage 6 when it moves between the two support columns 1.

[0034] Please see Figure 1 , Figure 2 and Figure 3 There are two push rods 10. Two limit blocks 9 are provided at one end of the two push rods 10. Two swing rods 11 are hinged to one side of the other end of the two push rods 10 through two hinge frames. One end of the two swing rods 11 is hinged to both ends of one side of the connecting plate 12 through two hinge frames. The movement of the connecting plate 12 can drive the two swing rods 11 to move the two push rods 10, so that the two push rods 10 can drive the two limit blocks 9 to be inserted into the limit grooves 21 inside the two support uprights 1.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The bottom of the cage 6 is provided with four support feet 22 at the four corners. The support feet 22 can support the cage 6 and increase the height of the cage 6 when it is parked on the ground, so as to prevent the cage 6 from being crushed by the bottom parts when it is parked on the ground.

[0036] Please see Figure 3 and Figure 5The inner wall of the connecting plate 12 is slidably disposed on the outer surface of the middle part of the limiting rod 15. The two ends of the limiting rod 15 are disposed at the bottom of the cage 6 through fixing plates. One end of the limiting rod 15 has a quadrilateral cross section. By sliding the inner wall of the connecting plate 12 on the outer surface of the middle part of the limiting rod 15, the angle of movement of the connecting plate 12 can be fixed, thereby improving the stability of the connecting plate 12 when it moves.

[0037] Please see Figure 3 and Figure 5 A fixing ring 16 is provided on the outer surface of one end of the limiting rod 15. A spring 17 is provided on one side of the fixing ring 16. One end of the spring 17 is provided on one side of the connecting plate 12. The spring 17 can apply a pushing force to the connecting plate 12, which can push the connecting plate 12 to reset. This causes the push rod 10 to pull the limiting block 9 out of the limiting groove 21, thereby resetting the limiting block 9 and allowing the cage 6 to resume its raising or lowering operation.

[0038] Please see Figure 1 , Figure 3 and Figure 4 A guardrail 18 is hinged to one side of the hoisting cage 6 via a hinge frame, and a protective plate 19 is hinged to the other side of the hoisting cage 6 via a hinge frame. Both the guardrail 18 and the protective plate 19 are equipped with positioning locks that are compatible with the two sides of the hoisting cage 6. Opening the guardrail 18 allows for easy loading of goods into the hoisting cage 6, while closing the guardrail 18 protects the goods inside the hoisting cage 6. The protective plate 19 works in conjunction with the guardrail 18 to protect the goods inside the hoisting cage 6. When the protective plate 19 is flipped open, it will be laid in the gap between the hoisting cage 6 and the floor, facilitating the transport of goods from the hoisting cage 6 to the construction site on the designated floor, thus improving the safety of goods transport.

[0039] Please see Figure 3 , Figure 4 and Figure 5 A pusher 20 is provided on one side of the protective plate 19. One end of the pusher 20 is slidably connected to the outer surface of the push plate 13. The other side of the push plate 13 is set on one side of the connecting plate 12 by a fixing rod. By flipping open the protective plate 19, the pusher 20 can be driven to swing, so that one end of the pusher 20 slides on the outer surface of the push plate 13. This allows the push plate 13 to drive the connecting plate 12 to move. When the protective plate 19 is opened to move the goods in the cage 6, the limiting block 9 can be automatically inserted into the limiting groove 21 to fix the position of the cage 6.

[0040] In this embodiment, a material lifting device uses a push rod 10 to push a limiting block 9 into a limiting groove 21 between two adjacent limiting plates 8. This allows the limiting block 9 to work with the limiting groove 21 to fix the position of the cage 6. This achieves the effect of supporting the bottom of the cage 6 when the cage 6 stops at a high position to remove materials, preventing the cage 6 from falling due to the breakage of the lifting rope 5, and improving the stability and safety of the cage 6.

[0041] The working principle of the above embodiment is as follows: By releasing the positioning lock between the guardrail 18 and the cage 6, the guardrail 18 is opened, and the goods to be lifted are placed into the cage 6. The guardrail 18 is then closed using the positioning lock. The motor 4 operates, driving the winding roller 3 to rotate. The winding roller 3 winds up the hoisting rope 5, causing the hoisting rope 5 to move the cage 6 upward. At the same time, the slider 7 slides within the support column 1. When the cage 6 slides to the designated floor, the positioning lock between the protective plate 19 and the cage 6 is released, causing the protective plate 19 to swing downward and open, allowing it to be laid in the gap between the cage 6 and the floor. When the protective plate 19 opens, it causes one end of the pusher frame 20 to slide on the outer surface of the pusher plate 13, causing the pusher plate 13 to move the connecting plate 12 gradually toward the fixing ring 16, compressing the spring 17. When the connecting plate 12 moves... The swing arm 11 will swing, and when the swing arm 11 swings, it will drive the push rod 10 to move towards the corresponding support rod 1, so that the push rod 10 drives the limit block 9 to insert into the corresponding limit groove 21, so that the limit block 9 cooperates with the limit groove 21 to support the cage 6, and the goods are taken out from the cage 6 through the opened protective plate 19. After the goods in the cage 6 are taken out, the protective plate 19 is pushed upward to swing back to reset, and the protective plate 19 is relocked to one side of the cage 6 by the positioning lock. When the protective plate 19 swings back to reset, it will drive the push frame 20 to swing back to reset, so that the push frame 20 gradually releases the push on the push plate 13, so that the spring 17 releases the thrust and pushes the connecting plate 12 to gradually reset. When the connecting plate 12 resets, it will pull the limit block 9 out of the limit groove 21, release the restriction on the cage 6, and allow the winding roller 3 to drive the cage 6 to move again.
