Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting device technology, and in particular to a hoisting device for building, warehousing and logistics. Background Technology
[0002] A cantilever crane (or jib crane) is a small lifting device used for loading, unloading, and handling building materials and stored goods in construction and warehousing logistics. It can be defined as a lifting device with a cantilever structure supported by a column and capable of rotating around that column, which is electrically or manually driven to lift and move goods horizontally. Specifically, this device typically consists of a column, cantilever boom, rotating mechanism, hoist, control system, and rails. Its core function is to utilize the rotation of the cantilever and the lifting of the hoist to transfer goods short distances within a defined area (such as a warehouse, workshop, or construction site). Its applications are of significant value in the construction, warehousing, and logistics sectors.
[0003] Current cantilever cranes used in construction, warehousing, and logistics suffer from significant deficiencies in conductor arrangement and protection, easily leading to conductor damage and affecting equipment operation. Existing cantilever cranes typically employ multiple conductors (including power and control lines) arranged at the bottom of the boom via lifting rings to control the hoist's lifting and power transmission. These conductors stretch and contract with the hoist's movement and swing with the boom's rotation. However, during frequent stretching and swinging, the outer insulation layer of the conductors is prone to friction with the lifting rings and boom edges. Especially at the lifting ring connections, where the bending angle is large, long-term stress can easily lead to insulation cracking and exposed internal conductors. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to provide a hoisting device for building warehousing and logistics, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of this utility model provides a hoisting device for building warehousing and logistics, including a support column. Two corresponding upper and lower support plates are fixedly connected to the outer surface of the support column. A rotating rod is rotatably connected between the two support plates via a bearing. An electric guide rail is fixedly connected to the outer surface of the rotating rod. A movable frame is slidably connected inside the electric guide rail. An electric hoist is fixedly connected to the bottom of the movable frame. A first steel plate and a second steel plate are fixedly connected to the top surface of the electric guide rail. A crossbar is fixedly connected between the first steel plate and the second steel plate. One side of the movable frame is fixed... A limiting plate is connected to a crossbar. A first wire is fixedly connected to one side of the limiting plate. The first wire is fixedly connected to the control unit of the electric hoist. An L-shaped bracket is fixedly connected to the top surface of the first steel plate. A threaded post is threadedly connected to the top of the L-shaped bracket. A first clamping sleeve is rotatably connected to the bottom end of the threaded post through a bearing. A second clamping sleeve corresponding to the first clamping sleeve is fixedly connected to the inner wall of the L-shaped bracket. A second wire is clamped between the first clamping sleeve and the second clamping sleeve. A spiral wire is fixedly connected between the second wire and the first wire. The crossbar is located inside the spiral wire.
[0007] Preferably, in any of the above embodiments, a bracket is fixedly connected to the top of the supporting column, a motor is fixedly connected to the top of the bracket, and gears are fixedly connected to the output end of the motor and the top of the rotating rod, with the two gears meshing with each other.
[0008] Preferably, one side of the limiting plate has a limiting hole, and the limiting plate is slidably connected to the crossbar through the limiting hole.
[0009] Preferably, one side of the support column has a threaded hole, the end of the second conductor away from the helical conductor passes through the threaded hole and is located inside the support column, and the end of the second conductor away from the helical conductor is fixedly connected to an external threaded disc, which is threadedly connected to the support column through the threaded hole.
[0010] Preferably, in any of the above solutions, the top of the first clamping sleeve is fixedly connected to two symmetrically arranged guide rods, and both guide rods are slidably connected to the L-shaped bracket.
[0011] Preferably, in any of the above embodiments, the inner wall of the bracket has two symmetrically arranged reinforcing ribs fixedly connected, and the bottom ends of the two reinforcing ribs are fixedly connected to the supporting column.
[0012] Preferably, in any of the above solutions, the inner walls of both the first clamping sleeve and the second clamping sleeve are fixedly connected with a plurality of linearly arrayed arc-shaped rubber pads.
[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0014] 1. The combined design of the spiral guide wire and clamping sleeve effectively solves the problem of wire breakage caused by stretching and swaying. The spiral guide wire, shaped like a spring, is sleeved on the outside of the crossbar. When the moving frame slides along the electric guide rail, the spiral guide wire can extend and retract with the movement of the limiting plate, avoiding direct pulling force on the first and second guide wires. The threaded column on the L-shaped bracket drives the first and second clamping sleeves to cooperate, firmly clamping the second guide wire. The arc-shaped rubber pad can buffer the vibration of the guide wire and reduce friction and wear. At the same time, the crossbar provides internal support for the spiral guide wire, preventing it from excessive bending or tangling, ensuring that the wire insulation layer is not scratched by the edge of the boom or other components, extending the service life of the guide wire, and ensuring stable transmission of power and control signals of the electric hoist.
[0015] 2. The coordinated design of the limiting and fixing structures enhances the overall stability and operational reliability of the device. The limiting plate slides through the limiting hole to the crossbar, restricting the movement trajectory of the moving frame and preventing uneven force on the conductor due to deviation. The threaded hole of the support column mates with the external threaded disc to fix the second conductor inside the support column, preventing the conductor from swaying when the rotating rod rotates. The guide rod ensures the smooth lifting and lowering of the first clamping sleeve, allowing the clamping force to be applied evenly to the second conductor. The reinforcing ribs of the bracket strengthen the connection between the motor and the support column, reducing the impact of vibration during the rotation of the rotating rod on the conductor. The combined effect of these multiple structures ensures the flexible operation of the hoisting device while improving the standardization and safety of the conductor layout, adapting to the complex operating environment of construction, warehousing, and logistics.

Detailed Implementation
[0022] 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 thereto.
[0023] like Figures 1 to 5 As shown, a hoisting device for building warehousing and logistics includes a support column 1. Two corresponding support plates 2 are fixedly connected to the outer surface of the support column 1. A rotating rod 3 is rotatably connected between the two support plates 2 via bearings. An electric guide rail 7 is fixedly connected to the outer surface of the rotating rod 3. A movable frame 8 is slidably connected inside the electric guide rail 7. An electric hoist 9 is fixedly connected to the bottom of the movable frame 8. A first steel plate 10 and a second steel plate 11 are fixedly connected to the top surface of the electric guide rail 7. A crossbar 12 is fixedly connected between the first steel plate 10 and the second steel plate 11. A limiting plate 13, which is slidably connected to the crossbar 12, is fixedly connected to one side of the movable frame 8. A first wire 14 is fixedly connected to one side of the limiting plate 13. The first wire 14 is fixedly connected to the control part of the electric hoist 9. An L-shaped bracket 15 is fixedly connected to the top surface of the first steel plate 10. A threaded post 16 is threadedly connected to the top of the L-shaped bracket 15. A first clamping sleeve 17 is rotatably connected to the bottom end of the threaded post 16 through a bearing. A second clamping sleeve 18 corresponding to the first clamping sleeve 17 is fixedly connected to the inner wall of the L-shaped bracket 15. A second wire 19 is clamped between the first clamping sleeve 17 and the second clamping sleeve 18. A spiral wire 20 is fixedly connected between the second wire 19 and the first wire 14. The crossbar 12 is located inside the spiral wire 20.
[0024] As an optional technical solution of this utility model, a bracket 4 is fixedly connected to the top of the support column 1, and a motor 5 is fixedly connected to the top of the bracket 4. Gears 6 are fixedly connected to the output end of the motor 5 and the top of the rotating rod 3. The two gears 6 are meshed together. The motor 5 drives the rotating rod 3 to rotate through gear transmission, so that the electric guide rail 7 and the moving frame 8 rotate synchronously with the rotating rod 3, realizing flexible adjustment of the hoisting range. The gear meshing transmission has high precision and stable power transmission, avoiding jamming when the rotating rod 3 rotates, and improving the operational flexibility and efficiency of the hoisting device.
[0025] As an optional technical solution of this utility model, a limiting hole 21 is provided through one side of the limiting plate 13. The limiting plate 13 is slidably connected to the crossbar 12 through the limiting hole 21. The limiting hole 21 is sleeved on the outside of the crossbar 12 to limit the lateral displacement of the moving frame 8 in the electric guide rail 7, so as to ensure that the moving frame 8 slides smoothly along the electric guide rail 7, avoid uneven force on the first wire 14 and the spiral wire 20 due to shaking, and ensure the stability of the wire connection.
[0026] As an optional technical solution of this utility model, a threaded hole 22 is provided through one side of the support column 1. The end of the second wire 19 away from the spiral wire 20 passes through the threaded hole 22 and is located inside the support column 1. The end of the second wire 19 away from the spiral wire 20 is fixedly connected to an external threaded disc 23. The external threaded disc 23 is threadedly connected to the support column 1 through the threaded hole 22. This fixing method can prevent the second wire 19 from shaking when the rotating rod 3 rotates or the moving frame 8 slides, avoid the wire from being damaged by friction with other components, and at the same time make the wire arrangement more regular and convenient for later maintenance.
[0027] As an optional technical solution of this utility model, the top of the first clamping sleeve 17 is fixedly connected to two symmetrically arranged guide rods 24. Both guide rods 24 are slidably connected to the L-shaped bracket 15. The guide rods 24 restrict the movement direction of the first clamping sleeve 17, so that it can only move in the vertical direction, ensuring that the first clamping sleeve 17 and the second clamping sleeve 18 are accurately aligned and the second wire 19 is evenly clamped, avoiding damage to the wire due to clamping deviation.
[0028] As an optional technical solution of this utility model, the inner wall of the bracket 4 is fixedly connected with two symmetrically arranged reinforcing ribs 25. The bottom ends of both reinforcing ribs 25 are fixedly connected to the support column 1. The fixed connection between the reinforcing ribs 25 on the inner wall of the bracket 4 and the support column 1 can enhance the connection strength between the bracket 4 and the support column 1. The reinforcing ribs 25 disperse the vibration force generated by the motor 5 during operation, prevent the bracket 4 from deforming due to long-term stress, ensure that the gear 6 at the output end of the motor 5 and the gear 6 at the top of the rotating rod 3 always maintain stable meshing, and ensure smooth rotation of the rotating rod 3.
[0029] As an optional technical solution of this utility model, the inner walls of both the first clamping sleeve 17 and the second clamping sleeve 18 are fixedly connected with a plurality of linearly arrayed arc-shaped rubber pads 26. The arc-shaped rubber pads 26 on the inner walls of the first clamping sleeve 17 and the second clamping sleeve 18 can play a buffering and protective role when clamping the second wire 19. The arc-shaped rubber pads 26 are in contact with the surface of the wire, which not only enhances the clamping friction and prevents the wire from slipping, but also avoids the squeezing and wear caused by direct contact between the metal clamping sleeve and the wire, thus protecting the insulation layer of the wire.
[0030] A hoisting device for building warehousing and logistics operates on the following principle:
[0031] 1) The spiral wire 20 is spring-shaped and sleeved on the outside of the crossbar 12. When the moving frame 8 slides along the electric guide rail 7, the spiral wire 20 can extend and retract with the movement of the limiting plate 13, so as to avoid the first wire 14 and the second wire 19 being directly pulled by force.
[0032] 2): The threaded post 16 on the L-shaped bracket 15 drives the first clamping sleeve 17 to cooperate with the second clamping sleeve 18, which firmly clamps the second wire 19. The arc-shaped rubber pad 19 can buffer the vibration of the wire and reduce friction and wear.
[0033] 3): The crossbar 12 provides internal support for the spiral conductor 20, preventing it from bending or tangling excessively, ensuring that the conductor insulation layer is not scratched by the edge of the boom or components, and extending the service life of the conductor.
[0034] In summary, this hoisting device for building storage and logistics effectively solves the problem of wire breakage caused by stretching and swinging through the combination design of spiral guide wire and clamping sleeve. The spiral guide wire 20 is spring-shaped and sleeved on the outside of the crossbar 12. When the moving frame 8 slides along the electric guide rail 7, the spiral guide wire 20 can extend and retract with the movement of the limiting plate 13, avoiding direct force pulling on the first guide wire 14 and the second guide wire 19. The threaded column 16 on the L-shaped bracket 15 drives the first clamping sleeve 17 to cooperate with the second clamping sleeve 18 to firmly clamp the second guide wire 19. The arc-shaped rubber pad 19 can buffer the vibration of the guide wire and reduce friction and wear. At the same time, the crossbar 12 provides internal support for the spiral guide wire 20, preventing it from excessive bending or tangling, ensuring that the wire insulation layer is not scratched by the edge of the boom or components, extending the service life of the guide wire, and ensuring stable transmission of power and control signals of the electric hoist 9. The coordinated design of the limiting and fixing structures improves the overall stability and operational reliability of the device. The limiting plate 13 is slidably connected to the crossbar 12 through the limiting hole 21, restricting the movement trajectory of the moving frame 8 and preventing it from deviating and causing uneven force on the conductor. The threaded hole 22 of the supporting column 1 cooperates with the external threaded disc 23 to fix the second conductor 19 inside the supporting column 1, preventing the conductor from shaking when the rotating rod 3 rotates. The guide rod 24 ensures that the first clamping sleeve 17 rises and falls smoothly, so that the clamping force is evenly applied to the second conductor 19. The reinforcing rib 25 of the bracket 4 enhances the connection strength between the motor 5 and the supporting column 1, reducing the impact of vibration on the conductor when the rotating rod 3 rotates. The combined effect of multiple structures ensures the flexible operation of the hoisting device and improves the standardization and safety of the conductor layout, adapting to the complex operating environment of building warehousing and logistics.
