Description

Technical Field

[0001] The utility model relates to the technical field of goods hoists, in particular to a safety protection buffer device for goods hoists. Background Technique

[0002] A goods hoist is a mechanical device capable of vertically transporting goods. A goods hoist generally consists of basic components such as a motor, a reducer, a conveying sprocket, a chain, and a hopper (or a loading platform). Its working principle is that the motor provides power, the reducer converts high-speed rotation into low-speed rotation, and the movement of the conveying sprocket and the chain drives the hopper (or the loading platform) to move vertically or obliquely up and down, thereby realizing the vertical or oblique lifting of goods.

[0003] The loading platform is one of the important components of the goods hoist. When a heavier object is moved to the top of the loading platform, when the heavier object is placed on the stationary loading platform, due to inertia, the object will generate a force in the opposite direction of the movement. When this force is suddenly applied to the hoist, it will form an impact. If the object is placed in the wrong way (such as hitting the cargo hold violently), the generated impact will be greater, and the impact force will damage the loading platform and the hoist. In view of this, we propose a safety protection buffer device for goods hoists. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a safety protection buffer device for goods hoists.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] The safety protection buffer device for goods hoists includes a base. On both sides of the top of the base, two columns are fixed. Between the tops of the two columns, a cross-seat is fixed. A winch is installed on the top of the cross-seat, and a steel wire rope is wound around the drum of the winch.

[0007] Above the base, there is a cargo hold part, which includes a lifting plate. At both ends of the lifting plate, connection blocks are fixed, and the bottom end of the steel wire rope is fixed to the connection block. On the top of the lifting plate, a frame with an open top is fixed. Inside the opening of the frame, a plurality of airbag shock absorbers are installed. On the top of the lifting plate, a plurality of guide rods are also fixed. At the top opening of the frame, a liftable connection seat is slidably installed. A strip-shaped groove is opened at the bottom of the connection seat, and the guide rod passes through the strip-shaped groove and is slidably connected to the strip-shaped groove. On the top of the connection seat, a bearing plate for carrying goods is fixed.

[0008] On the top of the bearing plate, a fence is fixed. The front end face of the fence is open. On both inner walls of the two sides of the fence at the front end, two guide rails are fixed. A fixing hole is opened above the two guide rails. A detachable baffle is installed at the opening of the fence, and both ends of the baffle are slidably installed between the two guide rails.

[0009] Further, sliding cavities are provided at the top ends of both side walls of the baffle plate. Connecting rods are fixed in the sliding cavities. Springs are sleeved on the connecting rods. Sliders are also slidably installed in the sliding cavities. Slide holes for slidably connecting with the connecting rods are provided on the inner walls of the sliders. The ends of the springs abut against the sliders. Fixed heads are fixed on the outer walls of the sliders, and the fixed heads are inserted and matched with the corresponding fixed holes.

[0010] Further, connecting grooves are provided on both sides of the top of the baffle plate. Poking rods are slidably installed at the connecting grooves, and the poking rods are fixedly connected with the sliders.

[0011] Further, the cross-sectional shape of the frame is in a square shape, and the opening size of the frame is adapted to the size of the connecting seat.

[0012] Further, the cross-sectional shape of the enclosure is in a U shape, and the enclosure is fixedly connected with the bearing plate through bolts.

[0013] Further, the plurality of airbag shock absorbers are distributed in a matrix, and the airbag shock absorbers are fixedly connected with the lifting plate and the connecting seat through bolts.

[0014] Further, a plurality of tension plates are installed on the outer wall between the two struts, and the tension plates are fixedly connected with the struts through bolts.

[0015] Further, two vertical rods are fixed between the two struts. The vertical rods pass through the connecting blocks and are slidably connected with the connecting blocks.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. By providing the cargo compartment part: A plurality of airbag shock absorbers are installed between the lifting plate and the bearing plate. When heavy objects are carried to the top of the bearing plate, under the impact of the heavy objects, the bearing plate moves downward and the airbag bodies of the airbag shock absorbers are elastically deformed. During the elastic deformation process of the airbags, the air pressure in the air chambers will change, so as to achieve the functions of buffering and shock absorption through the change of air pressure, and then maintain the stability and safety of the cargo compartment part. This design can protect the bearing plate and the elevator from damage by taking appropriate buffering measures, and improve work efficiency and safety;

[0018] 2. By providing the enclosure and the detachable baffle plate, the goods placed on the bearing plate can be limited, avoiding the situation that the goods slide out of the bearing plate during the lifting process, and ensuring the safety of the lifting operation.

Specific implementation manner

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] This embodiment provides a technical solution:

[0030] Please refer to Figures 1 - 6As shown in the figure, the safety protection buffer device of the goods hoist includes a base 1. On both sides of the top of the base 1, two columns 10 are fixed. Between the tops of the two columns 10, a cross base 11 is fixed. A winch 13 is installed on the top of the cross base 11, and a steel wire rope is wound around the drum of the winch 13. Above the base 1, there is a cargo compartment part 2. The cargo compartment part 2 includes a lifting plate 20. At both ends of the lifting plate 20, connecting blocks 21 are fixed. The lifting plate 20 and the connecting blocks 21 are of an integrally formed structure, and the bottom end of the steel wire rope is fixed to the connecting block 21. On the top of the lifting plate 20, a frame 22 with an open top is fixed. Inside the opening of the frame 22, a plurality of airbag shock absorbers 23 are installed. On the top of the lifting plate 20, a plurality of guide rods 24 are also fixed. At the top opening of the frame 22, a liftable connecting seat 25 is slidably installed. A strip-shaped groove 250 is opened at the bottom of the connecting seat 25, and the guide rods 24 penetrate into the strip-shaped groove 250 and are slidably connected with the strip-shaped groove 250. On the top of the connecting seat 25, a bearing plate 26 for carrying goods is fixed. The bearing plate 26 and the connecting seat 25 are fixedly connected by bolts. On the top of the bearing plate 26, a fence 27 is fixed. The front end face of the fence 27 is open. On both inner walls of the fence 27 at the front end, two guide rails 271 are fixed. Above the two guide rails 271, a fixing hole 270 is opened. A detachable baffle 28 is installed at the opening of the fence 27, and both ends of the baffle 28 are slidably installed between the two guide rails 271.

[0031] Further, sliding cavities 280 are opened at the top ends of both side walls of the baffle 28. Link rods 282 are fixed in the sliding cavities 280. Spring 283 are sleeved on the link rods 282. In the sliding cavities 280, sliders 284 are also slidably installed. A sliding hole for slidably connecting with the link rod 282 is opened in the inner wall of the slider 284, and the end of the spring 283 abuts against the slider 284. Fixed heads 286 are fixed on the outer walls of the sliders 284, and the fixed heads 286 are inserted and matched with the corresponding fixing holes 270. This design facilitates the quick disassembly and assembly of the baffle 28, thereby meeting the requirements for loading goods.

[0032] In this embodiment, connection grooves 281 are opened at both sides of the top of the baffle 28. Shift rods 285 are slidably installed at the connection grooves 281, and the shift rods 285 are fixedly connected with the sliders 284. By means of the shift rods 285, it is convenient to push the sliders 284 to move, and thus it is convenient to adjust the position of the fixed heads 286.

[0033] In this embodiment, the cross-sectional shape of the frame 22 is in the shape of a rectangle, and the opening size of the frame 22 is adapted to the size of the connecting seat 25. This design is conducive to the lifting of the connecting seat 25 in the opening of the frame 22.

[0034] In this embodiment, the cross-sectional shape of the retaining wall 27 is U-shaped, and the retaining wall 27 is fixedly connected to the bearing plate 26 by bolts. The U-shaped design enables the retaining wall 27 to provide protection at the rear and left and right sides of the top of the bearing plate 26, and the bolt fixing method has the advantage of reliable connection.

[0035] In this embodiment, multiple airbag shock absorbers 23 are distributed in a matrix, and the airbag shock absorbers 23 are fixedly connected to the lifting plate 20 and the connecting seat 25 by bolts. The airbag shock absorbers 23 distributed in a matrix can provide better shock absorption and buffering effects on the bearing plate 26. The bolt fixing method ensures the connection stability between the airbag shock absorbers 23 and the lifting plate 20 and the connecting seat 25.

[0036] In this embodiment, multiple pull plates 12 are installed on the outer wall between the two struts 10, and the pull plates 12 are fixedly connected to the struts 10 by bolts. The arrangement of the pull plates 12 increases the connection stability and reliability between the two struts 10.

[0037] In this embodiment, two vertical rods 14 are fixed between the two struts 10. The vertical rods 14 pass through the connecting block 21 and are slidably connected to the connecting block 21. The arrangement of the vertical rods 14 plays a guiding role in the lifting of the lifting plate 20, ensuring the smoothness and stability of the lifting plate 20.

[0038] It can be understood that a limiting block is coaxially fixed at the top end of the guide rod 24 in this embodiment. The diameter of the limiting block is larger than that of the guide rod 24. This design can prevent the guide rod 24 from disengaging from the strip-shaped groove 250, ensuring the stability of the connecting seat 25.

[0039] It should be added that the slider 284 and the fixed head 286 are integrally formed in this embodiment. This design increases the connection strength between the slider 284 and the fixed head 286, ensures the connection stability between the slider 284 and the fixed head 286, and thus ensures the limiting effect of the fixed head 286 on the baffle 28.

[0040] During specific use, the user first transports the heavy object to the top of the bearing plate 26. When the heavy object touches the top of the bearing plate 26, a downward impact force is applied to the bearing plate 26. Under this impact force, the bearing plate 26 moves downward and drives the connecting seat 25 to move downward. The connecting seat 25 then applies a force to the multiple airbag shock absorbers 23. At this time, the multiple airbag shock absorbers 23 deform. Under the action of the airbag shock absorbers 23, the impact force is weakened. At this time, the impact force transmitted to the lifting plate 20 is weakened, and the impact force received by the entire device is weakened.

[0041] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the descriptions in the specification are only preferred examples of the present utility model, and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
