Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a hoisting device for a clay sand mold tray. Background Art

[0002] A clay sand mold tray is a mold support device used in casting production. Its main function is to provide a stable support foundation during the casting process, enabling the casting sand mold to remain stable during the pouring and cooling processes of the casting liquid. This type of tray is usually made of clay sand and other materials, and has excellent high-temperature resistance and wear resistance, capable of withstanding the high temperature and mechanical stress during the casting process. The clay sand mold tray is often large in size and heavy in weight during casting production, making manual handling difficult and prone to damage. A hoisting device can efficiently and safely carry out the handling and positioning of the tray, thus ensuring the smooth progress of the casting process. The hoisting device can improve production efficiency. Through the hoisting equipment, rapid tray transfer and replacement can be achieved, reducing the time required for manual handling, shortening the casting cycle, and improving the overall operation efficiency of the production line. This is particularly important for large-scale and batch production. Therefore, the hoisting device plays an indispensable role in the use of clay sand mold trays, not only improving work efficiency but also ensuring the safety and stability of the production process.

[0003] However, the existing technology usually adopts manual handling, which is inefficient, and the fixture during hoisting usually requires additional tools for locking, which is rather troublesome. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a hoisting device for a clay sand mold tray, which has the characteristic of locking by using gravity and can effectively improve the handling efficiency.

[0005] The purpose of the utility model is to provide a hoisting device for a clay sand mold tray, including a support frame. Support legs integrally formed with the support frame are provided at the four corners of the support frame. A cross bar integrally formed with the support frame is fixedly installed in the middle of the support frame. Grooves are provided on both sides of the cross bar. A moving device is arranged in the grooves. A first motor is fixedly installed at the bottom of the moving device. A traction rope is wound around the surface of the output end of the first motor. A connecting block is fixedly connected to the bottom of the traction rope. A clamping device fixed by using gravity is fixedly installed at the bottom of the connecting block. A tray body is placed below the clamping device.

[0006] Preferably, the mobile device includes a driven wheel rotatably installed in the groove. There is a driving wheel on one side of the driven wheel. Both ends of the driven wheel and the driving wheel away from the groove are rotatably installed with mobile frames. A second motor is fixedly installed on one side of the mobile frame. The bottom of the second motor is fixedly connected with a support platform. One end of the support platform is fixedly connected with the mobile frame. The output end of the second motor is fixedly connected with the driving wheel. The bottom of the mobile frame is fixedly connected with a first motor.

[0007] Preferably, the clamping device includes a fixed column. A sliding sleeve is sleeved on the surface of the fixed column. The bottom of the sliding sleeve is rotatably connected with a clamping block through a hinge. A baffle is fixedly installed at the bottom of the fixed column. A slider is fixedly installed at the top of the baffle. The slider is in contact with the clamping block.

[0008] Preferably, rounded corners are provided at the sharp corners of the support frame.

[0009] Preferably, mounting blocks are fixedly installed at the bottoms of the support legs. A plurality of mounting holes are provided in the middle of the mounting blocks.

[0010] Preferably, a limiting disc is fixedly installed at the output end of the first motor.

[0011] Preferably, a hook is fixedly installed at the bottom end of the towing rope. A ring is fixedly installed at the top of the connecting block. The towing rope is movably connected with the connecting block through the cooperation of the hook and the ring.

[0012] The working principle and usage principle of the present utility model are as follows: Just lift the sliding sleeve upward and insert the clamping block into the gap inside the tray body. At this time, the first motor can be started to rotate. The rotation of the first motor will drive the towing rope to contract. The contraction of the towing rope will drive the fixed column to move upward. The upward movement of the fixed column will drive the sliding sleeve to move upward. The upward movement of the sliding sleeve will drive the clamping block to move upward. Thus, the clamping block contacts the tray body. The gravity of the tray body will pull the clamping block downward. Thus, the clamping block drives the sliding sleeve to move downward. The downward movement of the clamping block will slide on the surface of the slider. Thus, the slider is pushed to make the clamping block open outward. Thus, the clamping block is clamped into the gap of the tray body. Thus, the tray body is lifted. At this time, the tray body can be transported by the mobile device.

[0013] Compared with the prior art, the beneficial effects of the present utility model are: Fixing by using the self-weight of the tray can effectively improve the clamping stability and also effectively improve the handling efficiency.

[0014] Compared with the prior art, the present utility model has the advantage of improving the handling efficiency by fixing with the self-weight of the tray. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0020] In order to make the technical means, creative features, achieved purposes and functions realized by the embodiments of the present application easy to understand, the embodiments of the present application will be further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0021] Figure 1Schematically shows a hoisting device for a clay sand mold tray of the present utility model, including a support frame 1. At the four corners of the support frame 1, there are support legs 12 integrally formed with the support frame 1. In the middle of the support frame 1, a cross bar 13 integrally formed with the support frame 1 is fixedly installed. On both sides of the cross bar 13, grooves 14 are provided. Inside the grooves 14, there is a moving device 2. At the bottom of the moving device 2, a first motor 15 is fixedly installed. On the surface of the output end of the first motor 15, a traction rope 16 is wound. At the bottom of the traction rope 16, a connecting block 17 is fixedly connected. At the bottom of the connecting block 17, a clamping device 3 fixed by gravity is fixedly installed. Below the clamping device 3, a tray body 18 is placed. At the sharp corners of the support frame 1, round corners 4 are provided. The round corners 4 can effectively reduce the damage caused by bumps and can also avoid scratching the user. At the bottom of the support legs 12, mounting blocks 5 are fixedly installed. In the middle of the mounting blocks 5, a plurality of mounting holes 51 are provided. The device can be fixedly installed by setting fixing tools such as bolts in the mounting holes 51. At the output end of the first motor 15, a limit disk 6 is fixedly installed. The limit disk 6 can effectively prevent the traction rope 16 from falling off. At the bottom end of the traction rope 16, a hook 7 is fixedly installed. At the top of the connecting block 17, a ring 71 is fixedly installed. The traction rope 16 is movably connected to the connecting block 17 through the cooperation of the hook 7 and the ring 71, thereby facilitating the classification of the clamping device and facilitating the user to move other items that can be carried by the hook 7 through the hook 7.

[0022] As Figure 2 and Figure 3 shown, the moving device 2 includes a driven wheel 21. The driven wheel 21 is rotatably installed in the groove 14. On one side of the driven wheel 21, there is a driving wheel 22. At the ends of the driven wheel 21 and the driving wheel 22 away from the groove 14, a moving frame 23 is rotatably installed. On one side of the moving frame 23, a second motor 24 is fixedly installed. At the bottom of the second motor 24, a support platform 25 is fixedly connected. One end of the support platform 25 is fixedly connected to the moving frame 23. The output end of the second motor 24 is fixedly connected to the driving wheel 22. At the bottom of the moving frame 23, the first motor 15 is fixedly connected.

[0023] In specific implementation, only need to start the second motor 24 to rotate. The rotation of the second motor 24 will drive the driving wheel 22 to rotate. The rotation of the driving wheel 22 will drive the driven wheel 21 and the moving frame 23 to move, thereby driving the first motor 15 and the traction rope 16 to move, and further driving the clamping device 3 and the tray body 18 to move.

[0024] As Figure 2 and Figure 4 shown, the clamping device 3 includes a fixed column 31. A sliding sleeve 32 is sleeved on the surface of the fixed column 31. At the bottom of the sliding sleeve 32, a clamping block 33 is rotatably connected through a hinge. At the bottom of the fixed column 31, a baffle 34 is fixedly installed. At the top of the baffle 34, a slider 35 is fixedly installed. The slider 35 is in contact with the clamping block 33.

[0025] In a specific implementation, simply insert the clamping block 33 into the gap of the tray body 18, and then start the first motor 15 to contract the towing rope 16 of the first motor 15, thereby lifting the fixed column 31. The upward movement of the fixed column 31 will drive the sliding sleeve 32 to move upward, and the upward movement of the sliding sleeve 32 will drive the clamping block 33 to move downward, so that the clamping block 33 contacts the tray body 18. At this time, the self-weight of the tray body 18 will pull the clamping block 33 downward, so that the clamping block 33 moves downward. The downward movement of the clamping block 33 will contact the slider 35 on the baffle 34, so that the clamping block 33 drives the sliding sleeve 32 to move downward. The downward movement of the clamping block 33 will slide on the surface of the slider 35, and then push the clamping block 33 to open outward through the slider 35, so that the clamping block 33 is clamped into the gap of the tray body 18. At this time, the tray body 18 can be lifted to facilitate the handling of the tray body 18.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
