Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, and in particular to a slag leakage prevention device for a large-angle corrugated sidewall belt conveyor. Background Art

[0002] The corrugated sidewall belt conveyor uses a conveyor belt with corrugated sidewalls and transverse partitions, which is particularly suitable for continuous conveying of bulk materials at large angles. Its main feature is that it can convey at large angles, which greatly saves the equipment footprint and achieves a conveying angle that ordinary and patterned belt conveyors cannot achieve (arbitrary arrangement within the range of 0° to 90°). It can be widely used in coal, chemical, electric power, building materials, metallurgy, grain, ports, ships and other industries. In recent years, with the increase in tunnel excavation construction projects such as urban subways and urban pipeline corridors, high-angle corrugated sidewall belt conveyors have been widely used in such projects. Since such projects are often located in the central blocks of the city and the construction site space is very limited, under such working conditions, the high-angle corrugated sidewall belt conveyor gives full play to its advantages, realizing the continuous transportation of TBM / shield excavation slag from a depth of tens of meters below the surface to the ground slag pool, thereby improving the excavation construction efficiency. The schematic diagram of the high-angle corrugated sidewall belt conveyor is shown in the figure below. Figure 1 shown.

[0003] However, since the slag transported in this type of construction is often very sticky, the ground unloading section cannot completely unload the slag, and a small amount of slag will adhere to the base belt and partitions. As the corrugated sidewall conveyor belt runs, the remaining slag will be brought back to the lower horizontal section, causing a large amount of slag to accumulate under the frame of the lower horizontal section, affecting the construction site environment. In severe cases, it will damage the conveyor and pose a safety hazard.

[0004] Due to the unique structural form of the corrugated sidewall conveyor belt, the unloading point cannot completely clean the slag attached to the conveyor belt. A certain amount of slag will be brought back to the lower horizontal section. When it accumulates to a certain level, it will affect the construction environment and equipment operation.

[0005] In order to solve the above technical problems, the prior art sets a slag collection device under the lower horizontal section, and then manually transports the slag to the loading point of the conveyor, and then uses the normal operation of the conveyor to transport the slag to the ground. Although this method is simple, it increases the labor intensity of personnel, and in order to ensure the safety of personnel, the slag removal process requires shutdown operation, which will have a certain impact on the construction progress.

[0006] Therefore, the existing method for processing slag in corrugated sidewall conveyor belts has a technical problem of low reliability. It can be seen that how to improve the reliability of the method for processing slag in corrugated sidewall conveyor belts is a problem that needs to be solved in the field. Summary of the invention

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific diagrams.

[0031] Embodiment 1:

[0032] The existing method for handling slag in corrugated sidewall conveyor belts has a technical problem of low reliability. In view of this technical problem, the present invention provides a slag leakage prevention device for a large-angle corrugated sidewall belt conveyor. The device realizes self-cleaning of slag in combination with the operation of the corrugated sidewall belt conveyor. Slag collecting troughs are arranged in the horizontal and turning sections and at the tail roller. The trough body formed by them is closely matched with the corrugated sidewall conveyor belt. The slag accumulated in the trough body can be scraped again to the load-bearing section and then transported to the ground through the slag collecting device and the operation of the corrugated sidewall conveyor itself. Such reciprocating operation can effectively solve the problem of slag leakage in the lower horizontal section of the large-angle corrugated sidewall belt conveyor.

[0033] The invention provides a slag leakage prevention device for a large-angle corrugated sidewall belt conveyor, see Figure 2-Figure 3 It includes a first slag collecting device 100 and a second slag collecting device 200. The trough body formed by the first slag collecting device 100 and the second slag collecting device 200 cooperates closely with the corrugated sidewall conveyor belt.

[0034] The first slag device 100 is arranged at the horizontal and turning sections of the conveyor, and its structure is adapted to the horizontal and turning sections of the conveyor, so that it can be closely attached to the bottom of the horizontal and turning sections of the conveyor. Figure 4 The first slag material device 100 includes a first slag receiving trough body 110 , a connecting rod assembly 120 and an adjustable leg assembly 130 .

[0035] The first slag receiving trough 110 is formed by bending a horizontal trough, wherein the bending section is matched with the turning section of the conveyor, and the horizontal section is matched with the horizontal section of the conveyor. The end face formed in the middle is tightly matched with the bottom belt of the corrugated sidewall conveyor, so that the slag falls into the bottom of the first slag receiving trough 110, and the operation of the corrugated sidewall conveyor itself can be used to scrape the slag accumulated in the trough again to the bearing section, and then transport it to the ground.

[0036] A reinforcing beam 111 is preferably welded below the horizontal section of the first slag receiving trough 110. Since the horizontal section is too long, the welding of the reinforcing beam 111 can form a supporting force for the horizontal section to prevent deformation.

[0037] The first slag receiving trough 110 is symmetrically provided with adjustable leg assemblies 130, which are connected to the first slag receiving trough 110 via the connecting rod assembly 120. The height of the first slag receiving trough 110 can be adjusted by the adjustable leg assemblies 130 so that it can be closely matched with the corrugated sidewall conveyor belt. Figure 5 The adjustable leg assembly 130 includes a channel steel 131, a steel plate 132, a support plate 133, a connecting bottom plate 134 and an adjustment assembly.

[0038] The connecting bottom plate 134 is provided with a connecting hole, through which the connecting hole cooperates with the connecting piece to connect the adjustable leg assembly 130 to the lower horizontal section frame of the vertical belt conveyor. A channel steel 131 is provided on the connecting bottom plate 134, and a steel plate 132 and a mounting space of a support plate 133 are formed in the middle.

[0039] The support plate 133 is arranged in the installation space formed by the channel steel 131 , and its two ends are fixedly connected to the two ends of the channel steel 131 , respectively. The steel plate 132 is arranged on the support plate 133 , and a hole is opened in the middle thereof for connecting the connecting rod assembly 120 .

[0040] A mounting hole is provided on the support plate 133, which is used to set an adjustment component.

[0041] In some embodiments, the adjustment component may include a nut 136 and an adjustment bolt 135. The small head end of the adjustment bolt 135 passes through the bottom of the bottom. By rotating the adjustment bolt 135, the adjustment bolt 135 can be driven to rise and fall in the area formed by the steel plate 132 and the channel steel 131, and fixed with the nut 136.

[0042] The adjustable leg assembly 130 formed by the above scheme is arranged on both sides of the first slag receiving trough 110 through the connecting rod assembly 120. By adjusting the adjustable leg assembly 130, the connecting rod assembly 120 and the first slag receiving trough 110 connected to the other end of the connecting rod assembly 120 can be driven to rise and fall synchronously.

[0043] See also Figure 6 The connecting rod assembly 120 is welded by an angle steel 121 and a rectangular steel pipe 122. The angle steel 121 is arranged at the second end of the rectangular steel pipe 122. The first end of the rectangular steel pipe 122 is connected to the first slag receiving trough 110. After the second end passes through the opening of the steel plate 132, the angle steel 121 on the second end is fitted with the back of the steel trough 131. The connecting rod assembly 120 is limited by the angle steel 121 to prevent excessive lateral movement, thereby preventing the connecting rod assembly 120 from being separated from the adjustable leg assembly 130.

[0044] The second slag device 200 is arranged at the tail roller and overlaps with the end of the first slag device 100 to form a common trough. The structure of the second slag device 200 is adapted to the structure of the tail roller of the conveyor, so that it can be closely attached to the bottom of the tail roller of the conveyor. Figure 7 The second slag material device 200 includes a second slag receiving trough body 210 and a connecting bracket assembly 220 .

[0045] The second slag receiving trough 210 is configured as an arc structure according to the structure of the tail drum, and can be closely wrapped around the tail drum, so that the slag in the second slag receiving trough 210 can be scraped to the bearing section through the tail drum and then transported to the ground.

[0046] An angle steel 211 is preferably provided on the arc-shaped end surface of the second slag receiving trough 210. The angle steel 211 is provided on the arc-shaped end surface of the second slag receiving trough 210 to increase the strength of the second slag receiving trough 210 and prevent it from bending.

[0047] A connecting bracket assembly 220 is provided on both sides of the first end and the second end of the second slag receiving trough 210, and the second slag receiving trough 210 is connected to the tail roller support of the conveyor by the connecting bracket assembly 220. Figure 8 The connecting bracket assembly 220 includes a plurality of steel pipes and angle steels 224 .

[0048] In this solution, the plurality of steel pipes include a first steel pipe 221, a second steel pipe 222 and a third steel pipe 223. One end of the first steel pipe 221 is connected to the side wall of the second slag receiving trough 210, and the other end is connected to one end of the second steel pipe 222. The second steel pipe 222 and the first steel pipe 221 are arranged perpendicular to each other. The other end of the second steel pipe 222 is connected to the angle steel 224. During installation, the angle steel 224 is welded to the tail roller support. One end of the third steel pipe 223 is connected to the side wall of the second slag receiving trough 210, and the other end is connected to the second steel pipe 222 to increase the strength of the steel pipe.

[0049] The slag leakage prevention device for the high-angle corrugated sidewall belt conveyor formed by the above-mentioned scheme is equipped with slag collecting troughs at the horizontal and turning sections and the tail roller. The trough body formed by them is closely matched with the corrugated sidewall conveyor belt. The slag accumulated in the trough body is scraped again to the load-bearing section through the slag collecting device and then transported to the ground by the operation of the corrugated sidewall conveyor itself. Such reciprocating operation can effectively solve the problem of slag leakage in the lower horizontal section of the high-angle corrugated sidewall belt conveyor, and can realize self-cleaning of the slag in combination with the operation of the corrugated sidewall belt conveyor.

[0050] Embodiment 2:

[0051] The adjustable leg assembly 130 at the bottom of the first slag receiving trough 110 in Example 1 is fixedly adjusted. Based on Example 1, this embodiment further configures the adjustable leg assembly with a sensor system and a control system, and realizes automatic adjustment of the adjustable leg through the cooperation of the sensor system and the control system.

[0052] Specifically, the adjustable leg assembly is a telescopic rod, which is controlled by a control system. At the same time, the telescopic rod cooperates with the connecting rod assembly, and the telescopic rod can be controlled by the control system to be telescoped up and down.

[0053] Furthermore, the adjustable leg assembly is equipped with a sensor system, which includes a weighing sensor and a distance sensor.

[0054] Among them, corresponding to each adjustable leg assembly, a plurality of weighing sensors are provided at the end of the first socket body 110, and the materials transported on the conveyor belt are weighed in real time through the weighing sensors, and the weighing data are transmitted to the control system.

[0055] At the same time, corresponding to each adjustable leg assembly, a distance measuring sensor is provided at the edge of the end of the first socket body 110, and the distance measuring sensor is used to detect the distance between the conveyor belt and the end of the first socket body 110 in real time, and the measured data is transmitted to the control system.

[0056] The control system analyzes the data from several weighing sensors. If the weight of an object in a certain area is heavier or lighter than the set threshold, the data measured by the distance measuring sensor installed in the area are used to calculate the distance that the adjustable leg assembly needs to be adjusted. The control system then adjusts the adjustable leg assembly in the area upward or downward, thereby adjusting the height of the conveyor belt to prevent excessive scratching of the first bottom socket body 110 due to excessive weight of the material on the conveyor belt, which may cause damage to the conveyor belt or the conveyor belt may fail to fit with the first socket body 110, affecting the scraping of the slag.

[0057] Embodiment 3:

[0058] Based on Example 1, this embodiment sets the middle area of ​​the first socket body 110 as a soft body, and distributes a plurality of telescopic rods on both sides of the bottom of the first socket body 110. The plurality of telescopic rods cooperate with a control system to control the extension and retraction of the plurality of telescopic rods through the control system.

[0059] At the same time, a number of weighing sensors are provided on both sides of the bottom end of the first slag receiving trough body 110, and the weighing sensors are used to weigh the slag on the top of the first slag receiving trough body 110 in the corresponding area, and transmit the measured weight data to the control system, and the control system controls the telescopic rod to extend and retract according to the measured data.

[0060] Specifically, if the weight measured by the weighing sensor in an area is greater than the set threshold, the control system controls the telescopic rods at both ends of the bottom of the area to lift upward, thereby driving the two ends of the first socket body 110 to lift upward, so that the slag distributed on both sides of the first socket body 110 can be concentrated in the middle, avoiding excessive dispersion of the slag and affecting the reliability of slag scraping.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
