Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerated compartments, in particular to a refrigerated compartment hoisting device. Background Art

[0002] During the transportation of refrigerated compartments, a lifting device is required. The hook of an external crane is connected to the hanging ring of the lifting device, so that the lifting device clamps and fixes the refrigerated compartment to achieve lifting and transportation of the refrigerated compartment. The existing lifting device is very prone to unstable clamping during use, causing the refrigerated compartment to fall and be damaged, thereby reducing the lifting and transportation efficiency of the refrigerated compartment by the lifting device.

[0003] After searching, it was found that a solution for a lifting tool for a refrigerated compartment (Announcement No. CN217867692U) includes a main beam, a cross beam, a hanging ear, a sleeve and a limit block. Two cross beams are installed between the two main beams, a load-bearing beam is installed between the two cross beams, a hanging plate is installed on the upper surface of the load-bearing beam, and reinforcement plates are fixedly installed on the outer walls of both sides of the hanging plate. Limit blocks are installed on the outer wall of the bracket, and the outer wall of the limit block is connected with two bolts. Connecting seats are installed at both ends of the main beam, and the outer wall of the connecting seat is evenly provided with two threaded holes. When using the lifting tool for the refrigerated compartment, the compartment can be installed by placing it on the hanging ear, thereby reducing the previous step of repeatedly bundling the compartment with multiple sections of lifting ropes, achieving the goal of quickly lifting the compartment, reducing the labor intensity of employees, and improving production efficiency and safety. However, the clamping direction of the refrigerated compartment of the device is single, the clamping of the refrigerated compartment is unstable, and the refrigerated compartment is very likely to fall, reducing the lifting and transportation efficiency of the lifting device for the refrigerated compartment.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] The refrigerated compartment lifting device uses two pairs of clamping plates to initially clamp and fix the refrigerated compartment to be lifted and transported, and the four supporting plates provide a lifting effect on the refrigerated compartment, so that the moving block moves along the inner cavity of the telescopic outer plate, and the lateral extension length of the telescopic inner plate and the telescopic outer plate is adjusted. The provided pins fix the position of the telescopic inner plate, so that the limit plate moves to the specified position, and further clamps and fixes the refrigerated compartment.

[0025] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0027] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0028] In order to solve the problem that the refrigerated compartment lifting device is very likely to be unstable when it is in use, which reduces the lifting and transportation efficiency of the refrigerated compartment, please refer to Figures 1 to 5 The structure of the device body is as follows:

[0029] Four clamping plates 1 for clamping and fixing the refrigerated compartment enable the two pairs of clamping plates 1 to perform preliminary clamping and fixing of the refrigerated compartment. A support plate 2 for lifting the refrigerated compartment is welded to the side of the clamping plate 1, providing conditions for the hoisting and transportation of the refrigerated compartment and improving the hoisting and transportation stability of the refrigerated compartment by the hoisting device. A hollow telescopic outer plate 3 is welded to the centrifugal side of the two pairs of clamping plates 1, and the two clamping plates 1 welded to the telescopic outer plate 3 move synchronously in the same direction. The inner wall of the telescopic outer plate 3 is slidably connected to two moving blocks 4. The telescopic outer plate 3 is provided to fix the moving path of the two moving blocks 4.

[0030] The side of the moving block 4 is fixedly connected to a telescopic inner plate 5 with a plurality of through grooves on the top. The side of the telescopic inner plate 5 is fixedly connected to a limit plate 6 for clamping and fixing the refrigerated compartment. By adjusting the spacing between the two pairs of limit plates 6, the refrigerated compartment can be further clamped and fixed. At the same time, the clamping direction of the two pairs of clamping plates 1 and the two pairs of limit plates 6 to the refrigerated compartment is transversely perpendicular, thereby improving the clamping and fixing stability of the lifting device on the refrigerated compartment, preventing the refrigerated compartment from falling when the lifting device is lifting and transporting the refrigerated compartment, thereby improving the lifting and transportation efficiency of the refrigerated compartment by the lifting device, and at the same time making it easy to adapt the four limit plates 6 to refrigerated compartments of different sizes for clamping and fixing;

[0031] Through grooves are provided at both end surfaces of the telescopic outer panel 3. The inner walls of the through grooves at both end surfaces of the telescopic outer panel 3 are respectively slidably connected with the two telescopic inner panels 5, so that one telescopic outer panel 3 fixes the moving path of the two telescopic inner panels 5. At the same time, a moving block 4 is provided to prevent the telescopic inner panel 5 from separating from the telescopic outer panel 3 during movement, thereby improving the structural stability of the device parts. Through grooves are provided at both ends of the top of the telescopic outer panel 3. A latch 7 is inserted into the inner wall of the through groove of the telescopic outer panel 3. The end surface of the latch 7 passes through the telescopic inner panel 5, so that the latch 7 extends into the through groove of the telescopic outer panel 3 and the through groove of the telescopic inner panel 5 at the same time, thereby fixing the relative position of the telescopic inner panel 5 and the telescopic outer panel 3;

[0032] A hanging ring 8 is welded to the bottom surface of the hanging ring 8 with a cross-shaped fixing plate 9, and the end surface of the fixing plate 9 is welded to the inner wall of the fixing frame 10, so that the hanging ring 8 is hooked with the hook of the external crane, so that the refrigerated compartment clamped and fixed by the lifting device can be lifted and transported;

[0033] The fixing frame 10 is welded with support frames 11 on both sides, and the adjacent sides of the two support frames 11 are welded to the fixing frame 10. The inner side wall of one of the support frames 11 is rotatably connected to a threaded rod 12 with reverse threads, and the threaded rod 12 is threadedly connected to two threaded blocks 13 with reverse threads. When the threaded rod 12 rotates, the two threaded blocks 13 move synchronously in opposite directions along the threaded path of the threaded rod 12. The two side surfaces of the two threaded blocks 13 are slidably connected to the support frame 11 to prevent the threaded blocks 13 from rotating synchronously with the rotation of the threaded rod 12, thereby improving the structural stability of the device parts. A sliding rod 14 is welded to the inner side wall of the other support frame 11. The side surfaces of the sliding rod 14 are slidably connected to two sliders 15. The provided sliding rod 14 provides a fixing effect on the moving path of the two sliders 15, and the two side surfaces of the two sliders 15 are slidably connected to the support frame 11;

[0034] An inverted U-shaped moving plate 16 is welded to the top surface of the threaded block 13 and the slider 15. Under the connection provided by the moving plate 16, the two pairs of clamping plates 1 are synchronously moved in opposite directions during the transmission process, and are adapted to clamp and fix refrigerated compartments of different sizes. At the same time, the clamping part of the refrigerated compartment is in the center position to prevent the refrigerated compartment from tilting during hoisting and transportation, thereby improving the hoisting and transportation stability of the refrigerated compartment by the hoisting device. The end face of the threaded rod 12 is connected to the output shaft of the rotating motor 17 through a coupling, and the fixed end of the rotating motor 17 is detachably connected to the support frame 11 by bolts. The set rotating motor 17 provides power so that the output shaft of the rotating motor 17 drives the threaded rod 12 to rotate during rotation.

[0035] The rotating motor 17 is a prior art, and its working principle, size and model are irrelevant to the function of the present application, so no further description is given. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention no longer explains the control method and circuit connection in detail.

[0036] How it works

[0037] When using the refrigerated compartment lifting device, the user starts the rotating motor 17. During the rotation of the output shaft of the rotating motor 17, the threaded rod 12 is driven to rotate, thereby causing the two threaded blocks 13 to move synchronously in the opposite direction. Under the connection of the moving plate 16, the two sliders 15 are moved in the opposite direction along the path of the slide rod 14, so that the two pairs of clamping plates 1 preliminarily clamp the refrigerated compartment.

[0038] The moving block 4 and the telescopic inner plate 5 move along the inner cavity of the telescopic outer plate 3, and the four limit plates 6 are adjusted to the specified position to further clamp and fix the refrigerated compartment. The pins 7 pass through the telescopic inner plate 5 and the telescopic outer plate 3 respectively to fix the position of the telescopic inner plate 5. At the same time, the four support plates 2 are located at the bottom of the refrigerated compartment for support, so that the hook of the external crane is hung with the hanging ring 8 to lift and transport the refrigerated compartment.
