Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, relates to the field of production equipment, and particularly relates to a device structure for placing the stuck balls of a hoist. Background Technique

[0002] During the production and processing of steel balls, the steel balls will be drained through a ball track and conveyed onto a chain hoist for transferring the steel balls. However, when the chain hoist is running, there is a lot of friction between its chain and the chuck, which causes the chain to swing slightly back and forth, resulting in the hopper being easily stuck with the ball track.

[0003] Due to the position of the ball track, after the hopper is stuck, in the light case, it will cause the motor of the chain hoist to be overloaded, thus triggering the protection mechanism and causing the chain hoist to stop. In the serious case, it will cause the chain to break, resulting in a greater potential safety hazard and the need for maintenance and repair, increasing the use cost. Content of the Utility Model

[0004] In order to solve the technical problems that there are potential safety hazards and the use cost will be increased after the chain hoist is stuck with the ball track, the utility model provides a device structure for preventing the hoist from getting stuck with balls. By erecting an external ball track with a movable bottom plate between the original ball track and the chain hoist, the movable bottom plate can prevent the ball track from getting stuck with the hoist, making the use smoother, ensuring the use safety and reducing the use cost.

[0005] The technical solution adopted by the utility model is: to provide a device structure for preventing the hoist from getting stuck with balls, which includes the original ball track erected by means of a bracket, and also includes a bracket. The bracket is connected to the bracket on the original ball track by means of a telescopic member, and an external ball track is erected on the bracket. The external ball track is connected to the original ball track; the external ball track includes a bottom plate and side plates fixedly installed on both sides thereof. The bottom plate of the external ball track includes a fixed plate arranged at the starting end of the external ball track and a movable plate arranged at the end of the ball track. The fixed plate is fixed on the external ball track. One side of the movable plate close to the fixed plate is rotatably hinged on the external ball track, and a support piece is arranged at the bottom of the free end of the movable plate. Both ends of the support piece are fixedly installed on the side plates, and a buffer pad is sleeved on the support piece, and the buffer pad abuts against the movable plate.

[0006] The bracket mounts the peripheral ball track between the original ball track and the chain elevator. The bracket is connected to the bracket of the original ball track by means of a telescopic member. The telescopic amount of the telescopic member is adjustable to adjust the position of the bracket so as to align and connect the peripheral ball track with the original ball track, so that the steel balls can roll smoothly along the spliced ball track, ensuring the flexibility of use. The bottom of the peripheral ball track is composed of a fixed plate and a movable plate. The movable plate is arranged on one side of the chain elevator. After the steel balls roll onto the movable plate, they roll into the hopper of the chain elevator. The movable plate is rotationally hinged to the peripheral ball track. After the hopper gets stuck with the movable plate, the hopper drives the movable plate to rotate upward. As the movable plate rotates, it gradually disengages from the hopper and falls downward onto the support piece, releasing the jam between the movable plate and the hopper, ensuring the safety of equipment use. When the support piece supports the movable plate, the buffer pad on the support piece absorbs and consumes the impact generated by the falling of the movable plate, reducing the impact damage of the movable plate to the support piece and ensuring the reliability of use.

[0007] To further optimize this technical solution, the bracket includes a support plate arranged at the bottom of the peripheral ball track. The support plate is fixedly assembled with the peripheral ball track, and at least two legs are fixedly arranged along the length direction at the bottom end of the support plate. The legs are connected to the bracket by means of a telescopic member.

[0008] The bracket is supported by the legs for the support plate, and the support plate is fixedly assembled with the peripheral ball track to support the peripheral ball track. And the telescopic member is assembled on the legs and connected to the bracket, which is flexible to use.

[0009] To further optimize this technical solution, the telescopic member includes a threaded sleeve. Threaded rods are threadedly connected to both ends of the threaded sleeve. The threaded rods are respectively assembled with the legs and the bracket by means of fitting parts.

[0010] The threaded rods are respectively assembled on the legs and the bracket by means of fitting parts. The threaded rods are both threadedly connected to the threaded sleeve. As the threaded rods are threadedly engaged with the threaded sleeve, its telescopic amount is adjusted, thereby pulling the legs and the bracket closer to each other to dock the peripheral ball track with the original ball track. And the threaded engagement of the threaded rod and the threaded sleeve is simple to operate, and it ensures the firmness of the docking of the peripheral ball track and the original ball track, ensuring the reliability of use.

[0011] To further optimize this technical solution, the fitting part includes a hoop for assembling the bracket and the leg. A universal joint is assembled on the hoop, and the universal joint is rotatably installed with the threaded rod respectively.

[0012] The threaded rods are respectively assembled on the legs and the bracket by means of the hoop, which is simple to operate. And the hoop is assembled with the threaded rod by means of the universal joint to adapt to the assembly positions of the legs and the bracket, ensuring the flexibility of use.

[0013] To further optimize this technical solution, a rotating shaft is arranged on one side of the movable plate close to the fixed plate. Both ends of the rotating shaft protrude from both ends of the movable plate and penetrate through the side plate of the peripheral ball track, and are rotatably installed with the side plate of the peripheral ball track.

[0014] The movable plate is assembled on the peripheral ball track by means of a rotating shaft, with a simple structure, ensuring smooth and labor-saving upward rotation of the movable plate.

[0015] To further optimize this technical solution, elastic retaining rings are arranged at both ends of the rotating shaft. A rubber pad is arranged between the elastic retaining ring and the side plate of the peripheral ball track. The rubber pad is sleeved on the rotating shaft, and the end face of the elastic retaining ring abuts against the rubber pad.

[0016] Elastic retaining rings and rubber pads are sleeved at both ends of the rotating shaft. The elastic retaining rings and rubber pads prevent the rotating shaft from falling off the peripheral ball track, ensuring reliable use. Moreover, the contact between the rubber pad and the peripheral ball track reduces wear and extends the service life.

[0017] To further optimize this technical solution, a through hole is opened at one end of the movable plate close to the fixed plate. The rotating shaft is press-fitted into the through hole, and both ends of the rotating shaft penetrate through the through hole.

[0018] A through hole is opened on the movable plate for assembling the rotating shaft. The press-fitting of the rotating shaft and the through hole ensures that the movable plate and the rotating shaft rotate synchronously along the peripheral ball track, guaranteeing smooth use.

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. The fixed assembly of the support plate and the support legs supports the peripheral ball track, which is erected between the original ball track and the chain hoist. The brackets and supports for erecting the peripheral ball track and the original ball track are connected by means of telescopic members. The connection between the screw rod of the telescopic member and the threaded sleeve facilitates the adjustment of its telescopic amount, thereby pulling the brackets and supports to make the docking of the peripheral ball track and the original ball track firm and reliable, ensuring the smooth rolling of the steel balls, and the operation is simple and the use cost is low;

[0021] 2. The screw rods threadedly connected to both ends of the threaded sleeve are respectively connected to the hoop by means of universal joints. By assembling the hoops to the brackets and supports respectively, the installation is simple and efficient, and the universal joints can adapt to the installation positions of the hoops, ensuring the flexibility of use. When adjusting the position of the screw rod, the screw rod rotates along the universal joint, making the position adjustment of the screw rod convenient, and the assembly structure of the threaded sleeve and the screw rod is simple and the use is stable;

[0022] 3. One side of the bottom plate of the peripheral ball track close to the chain hoist is a movable plate. One end of the movable plate away from the hoist is hinged to the peripheral ball track by means of a rotating shaft. After the hopper of the chain hoist is stuck with the movable plate, the movable plate is lifted upward to avoid damaging the chain hoist. And after the movable plate is disengaged from the hopper, it falls back to the support piece under the action of gravity to support the movable plate for the steel balls to roll. The use is smooth, and the buffer pad on the support piece absorbs and consumes the impact force of the movable plate falling back, ensuring the safety of use. Description of the Drawings
