Fig. 1 shows a front view of a pipe expanding prevention device of a pipe belt conveyor according to an embodiment of the present invention in a use state. Fig. 2 is a side view of the pipe expanding prevention device of the pipe belt conveyor according to the embodiment of the present invention. As shown in fig. 1 and fig. 2, the pipe expansion preventing device 100 of the pipe belt conveyor of the present embodiment mainly includes a support 1, a telescoping mechanism 2, and a scraping assembly 3. An avoidance port for allowing the belt 200 of the tube belt conveyor to pass through is formed below the rack 1. The telescopic mechanism 2 is connected with the bracket 1 and is suitable for being telescopic along the vertical direction. The scraping component 3 is connected with the telescopic mechanism 2, and the scraping component 3 is positioned above the conveying belt 200 and is arranged at intervals with the conveying belt 200.

Known by the above technical scheme, the pipe expanding device 100 is used for installing before the afterbody becomes the pipeline section at pipe belt conveyor of this embodiment, in the use, when coal source end feed flow is unstable, when the material height that leads to on the conveyer belt 200 is higher than the bottom surface of scraping material subassembly 3, scrape the material mechanism and can offset with the material on the conveyer belt 200, thereby make the telescopic machanism 2 shrink, scrape the material mechanism simultaneously and can spread the material on the conveyer belt 200 evenly, avoid the filling rate of the interior local position material of pipe belt conveyor's pipe area to exceed standard and lead to taking place the expand tube phenomenon. Therefore, the tube expansion preventing device 100 for the tube belt conveyor of the embodiment can avoid the situation that the filling rate of materials at the local position in the tube belt of the tube belt conveyor exceeds the standard, and can avoid the situation that the carrier roller or the conveyor is overloaded and fails due to unstable feeding of the coal source end of the tube belt conveyor or the tube belt conveyor stops, so that the operation is more stable. In addition, the pipe expanding prevention device 100 of the pipe belt conveyor of the embodiment has a simple structure, is easy to manufacture, and is convenient to implement, popularize and apply.

In practical application practice, normally, the filling rate of the material in the pipe should not be greater than 75%, and the maximum particle diameter should not be greater than 1/3 of the pipe diameter, and when the particle diameter of the material is greater than 2/3 of the pipe diameter, the filling rate of the material must be reduced to 44%. Therefore, the height of the scraper assembly 3 is preferably set such that: when the material just can pass under the scraping assembly 3 and the scraping assembly 3 is not moved upwards, the incoming material filling rate of the material in the pipe-forming section of the pipe belt machine is 50-60%.

The bottom surface of the baffle 31 can push the material when contacting the top surface of the material, thereby making the material distribution more uniform. Preferably, in the present embodiment, the bottom end of the baffle 31 is formed with an upwardly concave curved surface 32. Because the top surface of granular material is the curved surface 32 of epirelief generally in the transportation, consequently when baffle 31 was set to curved surface 32, the atress of baffle 31 is more even, and when the difficult pipe expander that takes place of messenger's pipe belt conveyor of the volume of material, baffle 31 is difficult for taking place the contact with the material, can reduce the resistance that the conveyer transportation received.

In this embodiment, the scraping assembly 3 further includes a material guide cover 33 connected to the baffle 31.

The limit switch 4 can control the stop of the pipe belt conveyor when being touched by the scraping component 3. When the height of the material on the conveyor belt 200 is higher than the bottom surface of the baffle 31, the material guide cover 33 can contact with the top surface of the material first, and the telescopic mechanism 2 is compressed under the pushing of the material, so that the scraping component 3 moves upwards. When the gap of the lower part of the baffle 31 can not be passed through by the massive material or the massive foreign matter, the space section between the baffle 31 and the conveying belt 200 reaches the limit position, the guide cover 33 can move upwards under the extrusion of the material, the limit switch 4 is used for controlling the stop of the pipe belt conveyor, the damage of the rubber belt caused by the fact that the massive material forcibly passes through the baffle plate under the action of the conveying belt 200 and enters the tubular belt is avoided, or the inside of the pipe belt is blocked and is difficult to take out. The height of the baffle 31 at which the cross section of the space between the baffle 31 and the conveyor belt 200 reaches the limit position is preferably set to a height at which the incoming material filling rate of the pipe segment of the pipe belt conveyor reaches 75%.

Preferably, in this embodiment, as shown in fig. 4, a reinforcing rib 35 is further formed between the outer side of the material guide cover 33 and the baffle plate 31, and the reinforcing rib 35 can enhance the connection strength between the material guide cover 33 and the baffle plate 31 and prevent the material guide cover 33 from deforming.

In the present embodiment, as shown in fig. 5 and 6, the tube-expanding preventing device 100 of the tube belt conveyor preferably further includes a guide mechanism 5.

The scraping member 3 is formed with a sliding protrusion 312 which protrudes into the chute 51. The bottom end of the sliding projection 312 is adapted to abut the abutment 52. When the sliding protrusion 312 abuts against the abutting portion 52, the scraping mechanism can be stably suspended above the conveyor belt 200, and the elastic property of the telescopic mechanism 2 is prevented from being affected by the long-term stretching state of the telescopic mechanism 2.

The telescoping mechanism 2 may be selected as a spring connected between the support 1 and the scraping mechanism, and preferably, as shown in fig. 7, in the present embodiment, the telescoping mechanism 2 includes a connecting rod, a first elastic member 22 and a second elastic member 23. Wherein the connecting rod passes through the bracket 1. The upper end of the connecting rod is formed with a first abutting portion 212, and the lower end of the connecting rod is formed with a second abutting portion 213. The first elastic member 22 is supported between the bracket 1 and the first abutting portion 212. The second elastic member 23 is supported between the bracket 1 and the second abutting portion 213.

Threaded rod 211 passes through bracket 1. The first abutting portion 212 is a baffle 31 sleeved on the threaded rod 211. A nut 214 is threadedly coupled to the threaded rod 211 and is located at an end of the barrier 31 remote from the first resilient member 22.

The sleeve and the first abutting portion 212 are integrated and the first abutting portion 212 is provided with a circular hole 11. The diameter of the circular hole 11 is smaller than the inner diameter of the sleeve. The first abutting part 212 can bear the elastic force of the spring without deformation, and has certain thickness and toughness;

specifically, in the present embodiment, a sleeve extending in the height direction may be optionally formed on the cross beam, and the threaded rod 211 passes through the sleeve and is threadedly coupled with the bolt.

In this embodiment, the tube expansion preventing device 100 of the tube belt conveyor further comprises a roller frame 6 connected with the support 1 and located in the avoidance port. The conveyor belt 200 of the tube belt conveyor is arranged on the rollers of the carrier roller frame 6.
