Description

Technical Field

[0001] The invention relates to the field of mining belt conveyors, in particular to a mining terrain-adaptive telescopic belt conveyor. Background Art

[0002] Among many transportation equipment, mining belt conveyors stand out for their excellent continuous operation capability and high transportation efficiency, becoming an indispensable key equipment in the mining industry. They can transport huge amounts of ore and bulk materials uninterruptedly and efficiently. At the same time, with their excellent long-distance transportation capabilities, they can easily meet the strict requirements for long-distance material transportation in mining operations.

[0003] However, the huge size and complex structure of mining belt conveyors make them difficult to assemble, increasing the difficulty of deployment and maintenance. Moreover, traditional designs are often unable to flexibly cope with diverse terrain conditions and changing transportation needs, limiting their scope of application and adaptability. In addition, as key components in belt conveyors, the degree of fit between rollers and conveyor belts directly affects the transportation efficiency and stability. Summary of the invention

[0004] In view of the above-mentioned existing problems, the present invention provides a mine-use adaptive terrain retractable belt conveyor and a round-surface roller thereof. The mine-use adaptive terrain retractable belt conveyor can adjust the inclination angle of the conveyor to adapt to the working requirements of different slopes, curvatures and complex terrains; the conveyor also realizes the close integration of the conveyor body and the conveyor belt, and the conveyor body is retractable and movable, and can be transferred and deployed between different working sites; the round-surface rollers also introduced in the present invention have a closer contact between the conveyor belt and the rollers than traditional trough-type rollers, can better support and guide the conveyor belt, reduce the friction between the rollers and the conveyor belt and the resistance during the conveying process, thereby reducing the wear of the conveyor belt and improving work efficiency.

[0005] The technical solution is as follows: a conveyor, including a crawler vehicle assembly, a multi-stage hydraulic leg system, a monitoring device, a telescopic frame system, a main telescopic rod, a telescopic connecting rod, a reel device, a round roller, a lower roller, a roller, and a conveyor belt.

[0006] The crawler vehicle assembly mainly bears the load of the conveyor and drives it to move; the multi-stage hydraulic leg system can support the middle part of the conveyor and drive the two ends of the conveyor to move up and down, thereby adjusting the inclination angle of the conveyor to adapt to different working environments; the monitoring equipment is responsible for monitoring the condition of the conveyor belt and issuing a fault alarm in time.

[0007] The telescopic frame system is composed of a main telescopic frame and telescopic legs; the main telescopic frame is responsible for driving the entire conveyor to extend or retract; the telescopic legs connect the main telescopic frame and the main telescopic rod, both guiding and limiting their range of motion.

[0008] The main telescopic rod not only plays a supporting role, but also drives the entire conveyor to retract through its movement; the telescopic connecting rod is composed of an outer connecting rod, an inner connecting rod and a spring. When the telescopic frame retracts, the telescopic connecting rod will lift the main telescopic frame, extend the telescopic legs, and retract the conveyor as a whole.

[0009] The reel device integrates a transmission shaft, a reel hydraulic telescopic rod and a support rod; the transmission shaft transmits power to drive the reel to rotate; the reel hydraulic telescopic rod pulls the conveyor belt to the support rod to prepare for subsequent belt winding operations; and the support rod provides necessary structural support.

[0010] The round rollers support the conveyor belt to help balance the weight of the materials and ensure a smooth transmission process; the lower rollers provide bottom support for the conveyor belt; the rollers are the main components of the conveyor to transmit power; the conveyor belt is a key component of material transmission and is responsible for transporting materials from one place to another.

[0011] The advantages of the present invention are: 1. A mine-use adaptive terrain retractable belt conveyor can retract the entire conveyor by moving the crawler assembly and auxiliary devices such as the telescopic link to move part of the telescopic frame system up and down, and then drive the entire conveyor to migrate and deploy between various work sites through the crawler assembly, thereby improving work efficiency; 2. A mine-use adaptive terrain retractable belt conveyor can adjust the inclination angle of the conveyor by driving the two ends of the conveyor up and down through the multi-stage hydraulic legs at both ends, and then support the middle part of the conveyor through the multi-stage hydraulic legs in the middle part to match different working terrains; 3. A mine-use adaptive terrain retractable belt conveyor can roll up the conveyor belt tightly through a reel device when it is retracted, realizing the integration of the conveyor body and the conveyor belt, and improving the flexibility and portability of the equipment; 4. The upper roller design of a mine-use adaptive terrain retractable belt conveyor adopts a round surface structure, which makes the roller fit more closely with the belt, better supports and guides the conveyor belt, reduces the friction and resistance between the roller and the conveyor belt, thereby reducing the wear of the conveyor belt and improving work efficiency.

[0028] Reference Figure 5 , Figure 6 , Figure 7 The reel device 5 includes a transmission shaft 51, a reel hydraulic telescopic rod 52, and a support rod 53; Figure 5 It is the position of the reel device 5 when the conveyor is working; the transmission shaft 51 is connected to the motor to drive the reel device 5 to rotate; the reel hydraulic telescopic rod 52 is installed on the support rod 53 to play the role of pulling the conveyor belt; the support rod 53 is installed on the transmission shaft 51 to play a supporting role.

[0029] Reference Figure 8 , Fig. 9 , Fig.10 The telescopic frame system 4 includes a main telescopic frame 41 and telescopic legs 42; the main telescopic frame 41 is connected by a connecting rod in the middle to play a telescopic role; the telescopic legs 42 are assembled on the legs that need to rise when the main telescopic frame 41 contracts, playing a guiding role.

[0030] Reference Fig.11 and Fig.12 The telescopic connecting rod 6 includes an inner connecting rod 61, an outer connecting rod 62, and a spring 63; the inner connecting rod 61 is connected to the outer connecting rod 62 for contraction to ensure that the overall shape change of the conveyor is not affected; the spring 63 is inside the outer connecting rod, and when it contracts, it will generate a force on the inner connecting rod to give a small thrust to the leg that needs to rise in the telescopic frame system 4, thereby assisting it in completing the contraction.

[0033] The multi-stage hydraulic leg system 10 is lowered back to the origin, and the main telescopic rod 7 is contracted by moving the crawler vehicle assembly 1 to drive the telescopic connecting rod 6 to lift part of the structure of the telescopic frame system 4 on the telescopic leg 42.

At the same time, the drum hydraulic telescopic rod 52 in the drum device 5 will lift the conveyor belt to the specified position, and the transmission shaft 51 rotates to drive the conveyor belt to be wrapped around the support rod 53 to complete the contraction of the conveyor.

[0034] According to the length L, height H and center axis of the roller group, three reference points are first established, and then these three reference points are used to define an arc surface. Furthermore, the relative position and structural form between the side rollers and the horizontal rollers are determined in combination with the parameters of angle θ, length L1 and height H1; compared with trough rollers, round rollers fit the conveyor belt more closely, making the material transmission smooth and stable. Anti-deviation rollers are also installed above the side rollers to prevent the conveyor belt from deviating.
