Description

Technical Field

[0001] This utility model relates to the field of buffer technology for bulk material conveying and transfer points, specifically a composite heavy-duty buffer bed with adjustable groove angle and buffer module. Background Technology

[0002] To reduce damage to the belt, idlers, and other equipment caused by materials at the material transfer points of the belt conveyor, buffer devices such as buffer idlers, buffer beds, and combined buffer beds are usually installed at the material drop points of the belt conveyor.

[0003] However, traditional buffer rollers are prone to severe deformation of the crossbeam due to material impact, the rubber rings of the buffer rollers are prone to falling off and have a short service life, the edges of the rollers are severely worn and easily scratch the conveyor belt, and the conveyor belt is prone to longitudinal tearing at the overlap of two rollers.

[0004] Conventional buffer beds have relatively weak frame strength, the buffer strips are prone to falling off, they cause severe wear on the conveyor belt, and the buffering effect is poor. They are not suitable for conveying materials with large capacity, large size, high belt speed, and large drop. Whether using buffer idlers alone or buffer beds alone, each has its own disadvantages and is not suitable for conveying materials with large capacity, large size, high belt speed, and large drop. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a composite heavy-duty buffer bed with adjustable groove angle and buffer module. In order to ensure the long-term stable operation of high belt speed belt conveyors, a buffer bed is added to one side of the buffer idler to effectively support the lower surface of the belt. The buffering effect is significant and it plays a good protective role for the belt.

[0006] The purpose of this utility model is achieved through the following technical solution: a composite heavy-duty buffer bed with adjustable groove angle and buffer module, including an intermediate frame, a roller base on the intermediate frame, a roller beam on the roller base, screw holes on the upper and lower surfaces of the roller base, which are respectively fixed to the intermediate frame and the roller beam with bolts, a buffer roller on the roller beam, a buffer bed on one side of the buffer roller, and a conveyor belt placed on the buffer roller and the buffer bed. The conveyor belt is a component of the belt conveyor for traction and material carrying.

[0007] The bottom of the buffer bed is provided with a buffer bed crossbeam, which is the load-bearing beam of the entire buffer bed. The bottom of the buffer bed crossbeam is provided with a buffer bed base, and a Rodda vibration damping block is provided between the buffer bed base and the intermediate frame.

[0008] The buffer bed includes inclined supports and several buffer slides. The inclined supports include a first inclined support and a second inclined support. Several slide grooves are provided on the inclined surfaces of the first and second inclined supports. The buffer slides are set in the slide grooves. Several first screw holes at different heights are provided on the first and second inclined supports to facilitate adjustment of the angle between the first and second inclined supports and the buffer bed crossbeam. The support angle of the buffer bed is adjusted by the cooperation of the first and second inclined supports with the first and second pins fixed on the buffer bed crossbeam and the first screw holes at different heights. The upper surface of the buffer roller is slightly higher than the plane of the buffer bed by 10-30mm. This design greatly reduces the sliding friction between the conveyor belt and the buffer slides, thereby reducing the wear of the non-working surface of the conveyor belt. More importantly, it effectively avoids safety accidents such as fires caused by high temperatures generated by continuous friction, and significantly improves the safety and stability of equipment operation.

[0009] The buffer bed base includes a first buffer bed base, a second buffer bed base, a third buffer bed base, and a fourth buffer bed base, which are arranged sequentially at the bottom of the buffer bed. The Rodda vibration damping block includes a first Rodda vibration damping block, a second Rodda vibration damping block, a third Rodda vibration damping block, and a fourth Rodda vibration damping block. A first Rodda vibration damping block is provided between the first buffer bed base and the intermediate frame, a second Rodda vibration damping block is provided between the second buffer bed base and the intermediate frame, a third Rodda vibration damping block is provided between the third buffer bed base and the intermediate frame, and a fourth Rodda vibration damping block is provided between the fourth buffer bed base and the intermediate frame.

[0010] The buffer slide bar is secured in the slide bar groove plate by T-bolts. The slide bar groove plate has a limiting effect on the buffer slide bar and also serves as a load-bearing function.

[0011] The inclined support is provided with a pin hole, a first screw hole and several second screw holes. The inclined support is connected to the buffer bed beam through the pin hole and the support. The inclined support is connected to the support through the first screw hole. The inclined support is connected to the buffer slide through the second screw hole. After inserting the inclined support into the support and adjusting it to the required groove angle, it is fixed with bolts.

[0012] The buffer strip includes a polyethylene plate, rubber, and a skeleton. The rubber is sleeved on the outside of the skeleton to form an elastic rubber layer. The rubber is flame-retardant and antistatic, and is used to absorb the initial impact energy. The polyethylene plate is placed on top of the rubber. The polyethylene plate is an ultra-high molecular weight polyethylene plate, which is designed to reduce the coefficient of friction. The skeleton is an aluminum alloy skeleton. The rubber and the aluminum alloy skeleton are made by vulcanization.

[0013] The buffer roller includes a buffer roller, side supports, and a center support. The buffer roller includes a first buffer roller, a second buffer roller, and a third buffer roller. The side supports include a first side support and a second side support. The center support includes a first center support and a second center support. The first center support has a left-inclined surface, and the second center support has a right-inclined surface. One end of the first side support is connected to the roller crossbeam, and the other end is connected to one end of the first buffer roller. The other end of the first buffer roller is connected to the left-inclined surface of the first center support. The first center support and the second center support are connected by the second buffer roller. The right inclined surface of the support column is connected to one end of the third buffer roller. One end of the second side support column is connected to the idler beam, and the other end is connected to the other end of the third buffer roller. In order to reduce maintenance time and improve the operating efficiency of the belt conveyor, and to quickly replace vulnerable parts such as buffer rollers and buffer strips without disassembling the chute, guide chute and belt above the belt, the side support column, middle support column and idler beam are connected with bolts. Only the bolts need to be removed to move the buffer roller out laterally along the belt conveyor. After replacing the buffer roller, it is pushed back to the installation position and fixed with bolts. The buffer strip can also be quickly replaced in the same way.

[0014] The idler base includes a first base and a second base, the idler beam includes a first crossbeam and a second crossbeam, and the buffer idler includes a first buffer idler and a second buffer idler. The first base and the second base are both located on the top of the intermediate frame. The first crossbeam is located on the top of the first base, the first buffer idler is located on the top of the first crossbeam, the second crossbeam is located on the top of the second base, the second buffer idler is located on the top of the second crossbeam, and the buffer bed is located between the first buffer idler and the second buffer idler.

[0015] The bottom of the intermediate frame is provided with a lower support roller, which is a rotating component that supports the lower conveyor belt.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model aims to solve the problem of severe belt wear and fire risk caused by the impact of large sharp materials (>200mm) and high drop (>5m) on existing belt conveyors under high belt speed (>4m / s) and large conveying capacity (>5000t / h) conditions. It is particularly suitable for harsh industrial scenarios such as mines, ports, and metallurgy, and can significantly improve the wear resistance, safety and operational stability of the conveying system.

[0018] 2. This utility model adopts a secondary buffer design. When the material falls and causes an impact, the rubber of the buffer strip first absorbs part of the energy; then, the Roda damping block further absorbs and dissipates the remaining impact energy, forming an effective secondary buffer. This dual buffer mechanism significantly reduces the direct impact and wear of the material on the upper surface of the conveyor belt, thereby greatly extending the service life of the conveyor belt.

[0019] 3. The first and second inclined supports of this utility model are provided with several first screw holes of different heights, which facilitates the adjustment of the angle between the first and second inclined supports and the buffer bed crossbeam. The support angle of the buffer bed can be adjusted by the cooperation of the first and second inclined supports with the first and second pins fixed on the buffer bed crossbeam and the first screw holes of different heights.
