Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of material conveying equipment, and particularly relates to a flat supporting device capable of detecting belt materials. BACKGROUND

[0002] Belt conveying is a material conveying method widely used in industrial production, which conveys materials from the starting point to the end point through a continuous belt. The belt conveying system mainly consists of a conveying belt, a driving device (such as a motor and a speed reducer), a supporting roller, a tensioning device, a support, and a control system. Its working principle is that the driving device drives the conveying belt to run, the materials are placed on the conveying belt and move with the belt, and finally reach the target position. Belt conveying has the advantages of long conveying distance, large conveying capacity, stable operation, and low energy consumption, and is suitable for horizontal or inclined conveying of various materials such as granular, powdery, and blocky materials. In the mining, metallurgy, chemical industry, power, building materials, and grain industries, belt conveying is widely used for the transportation of materials such as ore, coal, sand, cement, and grain.

[0003] The belt conveying system can also be designed as a fixed or mobile type according to the requirements to meet the conveying requirements of different scenes and significantly improve the production efficiency. However, the belt conveying device in the prior art is difficult to automatically judge the belt empty and heavy load running conditions, and it is difficult to judge whether there are materials on the belt, which causes the related supporting dust removal system and other equipment to continue to operate when the equipment is empty, resulting in energy waste and equipment wear and tear, and increasing the use and maintenance cost.

[0004] Therefore, there is a need for a flat supporting device capable of detecting belt materials to solve the problems raised in the background. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims to provide a flat supporting device capable of detecting belt materials to solve the problems raised in the background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A flat supporting device capable of detecting belt materials, comprising a bottom plate, a first support plate is fixed on the top end side of the bottom plate, the first support plate is provided with two and the two first support plates are symmetrically distributed, a first groove is formed at the top end of the two first support plates, a speed measuring flat supporting roller is arranged between the two first support plates, a front belt is arranged above the speed measuring flat supporting roller and a gap is arranged between the front belt and the speed measuring flat supporting roller, a second end shaft coaxially arranged with the speed measuring flat supporting roller and clamped in the first groove is fixed at both ends of the speed measuring flat supporting roller, a protrusion is fixed on the side surface of the speed measuring flat supporting roller, and a speed limiting stopper for sensing the protrusion is arranged on one side of the speed measuring flat supporting roller.

[0008] It needs to be explained in the scheme that a plurality of second support plates are fixed on the top end side of the bottom plate, two second support plates form a group, two groups of second support plates are provided and symmetrically distributed at both ends of the bottom plate, the top end of the second support plate is provided with a second groove, a supporting roller is arranged between two second support plates in a single group, the two ends of the supporting roller are fixed with first end shafts coaxially arranged with the supporting roller, the first end shafts are clamped in the second grooves, and the front belt is located above the supporting roller and the bottom surface of the front belt is in contact with the side surface of the supporting roller.

[0009] It is further worth mentioning that a gap of 1-2 cm is provided between the speed measuring flat supporting roller and the bottom surface of the front belt, a convex plate is fixed on the side surface of the first support plate, a threaded rod is threadedly connected to the convex plate, and the end of the threaded rod is in contact with the side surface of the second end shaft.

[0010] It needs to be further explained that a third support plate is fixed on the top end side of the bottom plate, and the speed limiting stopper is fixedly installed on the top end of the third support plate.

[0011] As a preferred, one end of the threaded rod away from the second end shaft is fixed with an end plate, and a rubber sleeve is sleeved on the surface of the end plate.

[0012] Compared with the prior art, the flat supporting device for detecting belt materials provided by the utility model has at least the following beneficial effects:

[0013] When the belt is stationary, the lower surface of the front belt and the speed measuring flat supporting roller have a gap, and the speed measuring flat supporting roller remains stationary without being affected by external force. When the belt runs with load, the front belt will be deflected downward due to the weight of the materials, and the side surface of the speed measuring flat supporting roller will be in contact with the front belt, driving the speed measuring flat supporting roller to rotate, and the protrusions are synchronously rotated. At this time, the speed limiting stopper periodically senses the protrusions on the speed measuring flat supporting roller, outputs a high-level electrical signal to the dust removal system, and starts the dust removal system. Due to factors such as production process and temporary failure, when the materials on the front belt are intermittent, the front belt returns to normal during the no-load running period, and is no longer in contact with the speed measuring flat supporting roller. The speed measuring flat supporting roller gradually slows down and stops, and the speed limiting stopper cannot sense the protrusions on the speed measuring flat supporting roller at the set frequency, so a low-level signal is output, and the dust removal system stops immediately. That is, when the speed measuring flat supporting roller is no longer in contact with the front belt, and the speed of the speed measuring flat supporting roller decreases, the switch is in an open state, and a low-level signal is output. In this way, the speed measuring flat supporting roller, the protrusions and the speed limiting stopper cooperate to judge whether there are materials on the belt during different periods of belt no-load and heavy-load running.

[0019] Further as Figure 1As shown, it is worth noting that the top end side of the bottom plate 14 is fixed with a plurality of second support plates 9, two second support plates 9 form a group, the second support plates 9 are provided with two groups and the two groups of second support plates 9 are symmetrically distributed at both ends of the bottom plate 14, the top end of the second support plate 9 is provided with a second groove 15, and the two second support plates 9 in a single group are provided with a carrier roller 10, both ends of the carrier roller 10 are fixed with a first end head shaft 12 coaxially arranged with the carrier roller 10, the first end head shaft 12 is clamped inside the second groove 15, and the front belt 1 is located above the carrier roller 10 and the bottom surface of the front belt 1 is in contact with the side surface of the carrier roller 10; In particular, during operation, the bottom of the front belt 1 is supported by the carrier roller 10, so that there is a certain gap between the ground and the speed flat roller 6, and the stability of the front belt 1 when conveying materials is improved.

[0020] Further as Figure 1 As shown, it is worth noting that the top end side of the bottom plate 14 is fixed with a plurality of second support plates 9, two second support plates 9 form a group, the second support plates 9 are provided with two groups and the two groups of second support plates 9 are symmetrically distributed at both ends of the bottom plate 14, the top end of the second support plate 9 is provided with a second groove 15, and the two second support plates 9 in a single group are provided with a carrier roller 10, both ends of the carrier roller 10 are fixed with a first end head shaft 12 coaxially arranged with the carrier roller 10, the first end head shaft 12 is clamped inside the second groove 15, and the front belt 1 is located above the carrier roller 10 and the bottom surface of the front belt 1 is in contact with the side surface of the carrier roller 10; In particular, during operation, the bottom of the front belt 1 is supported by the carrier roller 10, so that there is a certain gap between the ground and the speed flat roller 6, and the stability of the front belt 1 when conveying materials is improved.

[0021] The scheme has the following working process: when the belt is static, the lower surface of the front belt 1 and the speed measuring flat roller 6 have a gap, and the speed measuring flat roller 6 remains static due to the absence of external force. When the belt is running, due to the weight of the material, the front belt 1 will form a downward deflection and contact the speed measuring flat roller 6 on the side, driving the speed measuring flat roller 6 to rotate, and the speed measuring flat roller 6 drives the protrusion 3 to rotate synchronously.

[0024] In summary: when the belt is stationary, the lower surface of the front belt 1 and the speed measuring flat roller 6 have a gap, the speed measuring flat roller 6 remains stationary due to the absence of external force, when the belt is running, due to the weight of the material, the front belt 1 will form a downward deflection and contact the side of the speed measuring flat roller 6, driving the speed measuring flat roller 6 to rotate, the speed measuring flat roller 6 drives the protrusion 3 to rotate synchronously, at this time, the speed measuring limiter 5 periodically senses the protrusion 3 on the speed measuring flat roller 6, outputs a high-level electrical signal to the dust removal system, and starts the dust removal system. Due to factors such as production process, temporary failure, etc., when the material on the front belt 1 is intermittent, in the time period of no-load operation, the front belt 1 returns to normal and no longer contacts the speed measuring flat roller 6, the speed measuring flat roller 6 gradually slows down and stops, the speed measuring limiter 5 cannot sense the protrusion 3 on the speed measuring flat roller 6 according to the set frequency, and outputs a low-level signal, the dust removal system stops immediately. The height position of the speed measuring flat roller 6 can be adjusted by rotating the threaded rod 16 and moving the second end shaft 13, so as to adjust the gap between the speed measuring flat roller 6 and the lower surface of the front belt 1, and to ensure that the speed measuring flat roller 6 and the front belt 1 always have the best distance, thereby improving the overall practicality.
