Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of conveying equipment, and particularly relates to a flat-section pull-out type buffer bed connected by a pin shaft. BACKGROUND

[0002] The buffer bed is a substitute tool for the buffer roller, which can absorb impact, prevent belt tearing, reduce the impact and damage of materials to the belt, avoid the tearing and scratching of the belt by sharp objects, prevent material overflow and spilling, etc. The use of the buffer bed ensures the contact between the surfaces of the conveying belt, the uniform stress, effectively prevents the longitudinal tearing of the belt caused by the breakage and falling of the roller, and greatly reduces the probability of longitudinal tearing of the belt caused by the piercing of the belt by sharp objects or sharp materials. It plays an important protective role in the conveying belt system, can absorb and disperse the impact force caused by the impact of materials, thereby reducing the vibration and shearing of the belt and prolonging the service life of the belt.

[0003] The existing material receiving buffer bed (for example, application No. 201420003245.5, etc.) has the following problems in use:

[0004] 1. Welding or bolt fixation: welding is a permanent fixation method, which can provide very strong fixation force and ensure that the buffer bed will not move or fall off during use. However, welding also has its disadvantages. First, welding requires professional welding equipment and technology, which is complex to operate and has high cost. Second, the welded buffer bed is difficult to disassemble and replace. If the buffer bed is damaged or needs to be replaced, it may need to be re-welded, which is time-consuming and costly. In addition, welding may affect the performance of the material, such as causing thermal stress and deformation of the material. Bolt fixation is a detachable fixation method, which is simple to operate and has low cost. The bolt-fixed buffer bed can be easily disassembled and replaced, and has low maintenance and maintenance cost. However, due to the falling of the belt, the buffer bed is in a harsh vibration environment for a long time, and the bolt is prone to looseness and falling. In summary, the existing fixation methods have different disadvantages, so there is an urgent need for a buffer bed with a new fixation method.

[0005] 2. Beam is easily deformed: The buffer bed plays a role in absorbing and dispersing the impact force of the material in the conveying belt system. However, in traditional conveying belt systems, straight beam designs are mostly used. The linear or flat beam structure has limited dispersion capacity when subjected to impact. When the weight of the material is too large or the impact force is too strong, it may exceed the carrying capacity of the buffer bed, causing the beam to deform. Especially under long-term or high-frequency use, its impact resistance and stability are insufficient. This limitation makes the conveying belt system need frequent maintenance and replacement, increasing operating costs. Deformation of the beam affects the working effect and service life of the buffer bed, making the working surface of the buffer bed uneven, which affects the conveying effect and efficiency of the material. In severe cases, it may even cause the buffer bed to malfunction, further causing damage to the buffer bed.

[0006] 3. Buffer strip replacement is inconvenient: The buffer strip is easily worn out due to friction with the conveying belt and the impact of the falling material, resulting in a decrease in the buffering effect, so the buffer strip needs to be replaced in a timely manner. The existing buffer bed needs to lift or jack up the conveying belt before loosening the buffer strip bolts, then drill into the gap between the conveying belt and the buffer bed to lift the buffer strip and take it out. The operation is complex, the downtime is long, and it causes great loss to the user, so there is an urgent need for a new type of buffer bed that can easily replace the buffer strip.

[0007] 4. No buffering along the conveying belt movement direction: When the material moves on the conveying belt, it may cause unstable movement of the material, such as jumping and sliding, due to impact force or sudden changes in movement speed. Without buffering along the movement direction, it may cause the material to collide and rub against the conveying belt, resulting in damage such as tearing and wear.

[0008] 5. No buffer mechanism for side plates: The falling material does not always fall on the center of the buffer bed, but many times it falls on the side plates of the buffer bed. The existing buffer bed does not have a corresponding design for this situation. When larger materials fall on the side plates, without the corresponding lateral buffering mechanism, the material unloading force is not complete, increasing the risk of damage to the conveying belt.

[0009] 6. Defects in side plate height and angle adjustment mechanism: The existing buffer bed side plate angle adjustment device cannot achieve arbitrary angle adjustment, or the support structure is weak and easily deformed. However, different sizes and types of materials and different working conditions of the belt machine require different widths and forms of the conveying belt, which makes the buffer bed not always well adapted to each type of conveying belt, leading to increased wear and tear of the conveying belt and buffer bed, and a series of consequences such as decreased buffering and belt protection effect. SUMMARY

[0010] A flat section pull-out type buffer bed connected by pin shafts, comprising a cross beam, a middle plate, side plates, a transverse buffer mechanism, side supports, buffer strips, pin shafts, and pins;

[0011] The cross beam is designed in an arch shape and has several insertion holes;

[0012] The middle plate is slightly wider than the cross beam and has several insertion holes on both sides of the corresponding positions of the cross beam, and the upper surface of the middle plate is provided with several buffer strip support frames;

[0013] The lower end of the side plate has several insertion holes, and the upper surface of the side plate is provided with several buffer strip support frames;

[0014] The transverse buffer mechanism comprises a limiter, a guide rail, a sliding block, and a polyurethane buffer block, the lower part of the limiter has several insertion holes in the corresponding positions of the cross beam, the top of the limiter is provided with several guide rails, the middle section of the guide rail is slidingly installed with the sliding block, the both ends of the guide rail are slidingly installed with the polyurethane buffer block, and the upper surface of the sliding block has several protruding pins;

[0015] The side support comprises a jack and a polyurethane buffer pad, the upper end and the lower end of the jack are designed with insertion holes, and the polyurethane buffer pad is installed at the lower end of the jack through the pin shaft;

[0016] The buffer strip comprises a sliding rail fixing seat, a buffer layer, and a wear-resistant layer, the upper part of the buffer strip support frame is provided with the sliding rail fixing seat, the upper part of the sliding rail fixing seat is provided with the buffer layer, and the upper surface of the buffer layer is provided with the wear-resistant layer;

[0017] One end of the pin shaft has a small hole and is fixed with the pin;

[0018] The middle plate is connected to the cross beam through the pin shaft, the bottom of the side plate is inserted on the protruding pins of the sliding block and fixed with the pin, the transverse buffer mechanism is connected to the cross beam through the pin shaft, the upper end of the side support is connected to the upper end of the side plate through the pin shaft, and the lower end of the side support is connected to the cross beam through the pin shaft.

[0019] Further, the guide rail and the sliding block of the transverse buffer mechanism are in a sliding fit relationship, when impacted by materials, the sliding block can slide on the guide rail and cause the polyurethane buffer block to be extruded and deformed, thereby absorbing and dispersing the impact force.

[0020] Further, the guide rail and the sliding block of the transverse buffer mechanism are in a sliding fit relationship, when impacted by materials, the sliding block can slide on the guide rail and cause the polyurethane buffer block to be extruded and deformed, thereby causing the side plate to produce transverse displacement to absorb and disperse the impact force.

[0021] Further, a plurality of the buffer strips are installed on the buffer strip support frame.

[0022] Further, the middle plate can slide on the cross beam when the middle plate is not connected with the cross beam through the pin shaft.

[0023] Further, the height of the jack can be adjusted to achieve different inclination angles of the side plates.

[0024] Further, the polyurethane cushion can be deformed by the jack to buffer the impact force in the direction of the belt movement.

[0025] The present application has the following advantages:

[0026] 1. The pin shaft is used to connect all components: first, the design of pin shaft connection makes the installation and disassembly of the buffer bed simple, without the need for professional welding equipment and technology, and avoids the problems of thread damage or bolt loosening that may occur during bolt connection. This means that when the buffer bed needs to be replaced or repaired, the pin shaft can be easily removed, greatly reducing the workload and cost. Second, the pin shaft can provide strong fixing force to ensure that the buffer bed does not loosen or disintegrate as a whole or in part in a severe vibration environment, which is in sharp contrast to the possibility of bolt loosening. In addition, compared with welding and bolt connection, pin shaft connection does not generate thermal stress, does not cause material deformation, and does not affect the performance of the material, which ensures the performance and service life of the equipment. Finally, the pin shaft connection of the buffer bed only needs to replace the pin shaft when it needs to be repaired or replaced, without the need for re-welding like welding or checking and replacing multiple bolts like bolt connection, greatly reducing the cost of maintenance and replacement.

[0027] 2. The use of an arched cross beam: the design of the arched cross beam makes the buffer bed better withstand and disperse the impact force of the material, thereby avoiding the deformation of the cross beam. This not only improves the working effect and service life of the buffer bed, but also avoids the problem of uneven working surface caused by cross beam deformation, thereby affecting the material conveying effect and efficiency. In addition, the design of the arched cross beam can also prevent the buffer bed from not working normally or even being damaged due to excessive deformation of the cross beam. Therefore, the flat section pull-out type buffer bed with an arched cross beam has significant advantages over the prior art in terms of working effect, service life, and material conveying effect and efficiency.

[0028] 3. Side pull-out type buffer strip replacement method: The flat section pull-out type buffer bed designed in the present application uses pin shaft connection, and the buffer strips are installed on the middle plate and the side plate. When the buffer strips on the middle plate need to be replaced due to severe wear, the pin shaft at the connection between the lower part of the side support and the cross beam is pulled out first, and then the pin shaft at the connection between the transverse buffer mechanism and the cross beam is pulled out. In this way, the side plate, the side support and the transverse buffer mechanism can be taken down together, and then the pin shaft at the connection between the middle plate and the cross beam is pulled out. Thus, the part that needs to be replaced can be pulled out along the cross beam in the transverse direction without removing the belt, greatly simplifying the operation process, shortening the downtime and reducing the loss of the user. This design not only improves the convenience of buffer strip replacement, but also improves the working efficiency and service life of the buffer bed.

[0029] 4. Adding polyurethane buffer pads to buffer the impact in the direction of movement of the conveyor belt: The buffer pads can absorb and disperse the impact force generated during the movement of the material, reducing the collision and friction between the material and the conveyor belt, thereby protecting the conveyor belt and prolonging its service life. At the same time, the buffer pads can also make the movement of the material more stable, reducing phenomena such as jumping and sliding, and improving the conveying efficiency. Therefore, adding buffer pads in the direction of movement of the conveyor belt can effectively improve the performance of the buffer bed, protect the conveyor belt and improve the conveying efficiency.

[0030] 5. Adding a transverse buffer mechanism for the side plate: This design can make the side plate have a corresponding buffer mechanism to absorb and disperse the impact force when it receives the impact of the material, thereby better protecting the conveyor belt and the side plate and prolonging their service life. At the same time, this design can also make the material land more stably, reducing phenomena such as jumping and sliding of the material, and improving the conveying efficiency.

[0031] 6. Using a jack to adjust the inclination of the side edge: In the present application, the height and inclination of the side plate are adjusted by a jack, so that the side plate can adapt to different sizes and types of materials and the angle of the conveyor belt. This can better adapt to different conveyor belt forms, reduce the probability of material damaging the conveyor belt, and improve the service life of the belt conveyor. In addition, adjusting the height and inclination of the side plate by a jack is simple and convenient, and does not require complex tools and equipment, greatly reducing the operation difficulty and cost. If the side plate has a flatness problem, we can repair it by adjusting the jack without replacing the entire side plate, which greatly reduces the maintenance cost and time.
