Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, specifically relating to an installation structure for a belt misalignment detection switch. Background Technology

[0002] During the operation of a belt conveyor, the belt is prone to deviation when subjected to external forces. Usually, a set of deviation switches is installed at the head and tail of the belt conveyor to detect the belt running status, and the positions are relatively fixed.

[0003] The existing belt misalignment switches are basically either fixed or have extended contact guide rods. Fixed installation generally adopts a combination structure of a stop roller and a limit switch, including: (1) the stop roller is inside the machine head, and the limit switch is fixed on the outside of the machine housing, requiring a large space between the belt and the housing. (2) both the stop roller and the limit switch are placed inside the equipment. Over time, dust accumulates on the switch housing, and the switch wire also needs to be led out of the housing. The switch must meet the explosion-proof requirements of Zone 20.

[0004] During use, the belt will extend, and the height of the belt relative to the tail pulley will change. The existing fixed installation will cause the belt to run off track after tensioning, and the belt will not be able to contact the belt deviation switch when it runs off track, so it cannot be detected and alarmed, resulting in belt wear on the housing, material spillage, etc.

[0005] After the equipment has been used for a period of time, it needs to be tensioned again. The relative position of the belt and the belt misalignment switch has changed, causing the belt misalignment switch to fail. Utility Model Content

[0006] The purpose of this invention is to provide an installation structure for a belt misalignment detection switch, which solves the technical problem that the relative displacement of the belt and the misalignment switch in existing belt conveyors causes the misalignment switch to fail.

[0007] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a belt misalignment detection switch mounting structure, characterized in that it includes: The mounting plate is equipped with a belt misalignment detection switch. The adjusting plate assembly includes two adjusting plates, each with a connector, and the adjusting plates are positioned on both sides of the belt misalignment detection switch; The belt conveyor housing has a belt misalignment detection switch mounting hole and an adjustment hole on its side plate. The connecting piece passes through the adjustment hole and the mounting plate in sequence and is equipped with a locking piece. Adjust the vertical position of the connector in the adjustment hole, thereby adjusting the height of the belt misalignment detection switch so that the belt misalignment detection switch matches the tensioned belt.

[0008] When the relative position of the belt and the belt misalignment switch changes and the position of the belt misalignment switch needs to be adjusted, the mounting plate can be moved up and down to adjust the height of the belt misalignment detection switch, effectively preventing the belt misalignment switch from failing.

[0009] To solve the technical problem of inconvenient adjustment of the belt misalignment detection switch, this utility model adopts the following technical solution: the top of the mounting plate is provided with a bent part; When it is necessary to adjust the position of the belt misalignment switch, the bend can be used to easily move the sealing plate up and down to adjust the height of the belt misalignment detection switch, making the adjustment convenient.

[0010] To solve the technical problem of how to implement the adjustment hole, the present invention adopts the following technical solution: the adjustment hole is an oblong hole, and the adjustment hole is vertically arranged on the housing of the belt conveyor.

[0011] To address the technical problem of inaccurate adjustment with a single adjustment hole, this invention employs the following technical solution: four adjustment holes are respectively located at the four corners of the belt misalignment detection switch mounting hole. Utilizing four adjustment holes ensures consistent adjustment on both sides, improving accuracy.

[0012] To solve the technical problem of how to implement the adjusting plate, the present invention adopts the following technical solution: the adjusting plate is located inside the side plate of the belt conveyor housing; the adjusting plate and the connecting piece are arranged perpendicularly; the number of connecting pieces on each adjusting plate is 2; the adjusting plate is elongated.

[0013] To address the technical challenge of implementing the connecting component, this invention employs the following solution: the connecting component is a welded stud, and the locking component is a nut. When adjusting the position of the misalignment switch, only a slight loosening of the nut is required; there is no need to remove the welded stud, thus preventing the bolt from falling into the equipment during adjustment.

[0014] To solve the technical problem of the belt misalignment detection switch extending into the belt conveyor housing, the present invention adopts the following technical solution: the mounting plate is provided with a first mounting hole for mounting the belt misalignment detection switch; The first mounting hole is circular. The belt misalignment detection switch passes sequentially through the first mounting hole and the belt misalignment detection switch mounting hole on the side plate of the belt conveyor housing, and approaches the belt inside the belt conveyor.

[0015] To solve the technical problem of how to mount the belt misalignment detection switch on the mounting plate, the present invention adopts the following technical solution: the belt misalignment detection switch is provided with a mounting base; the mounting plate is provided with a second mounting hole for mounting the mounting base on the mounting plate; The second mounting hole is located outside the first mounting hole.

[0016] To solve the technical problem of how the connector passes through the mounting plate, the present invention adopts the following technical solution: a third mounting hole is provided on the mounting plate, the third mounting hole is located outside the corresponding second mounting hole, and the third mounting hole is used to install the connector.

[0017] To solve the technical problem of how to install the mounting base, the present invention adopts the following technical solution: the outer diameter of the mounting base is larger than the outer diameter of the first mounting hole, the mounting base is located outside the mounting sealing plate, and the mounting sealing plate is located outside the side plate of the belt conveyor housing.

Detailed Implementation

[0019] The present invention will be further described below with reference to the figures.

[0020] Example 1 like Figure 1-3 As shown, the belt misalignment detection switch mounting structure 100 includes a mounting cover plate 110 and an adjusting plate assembly 120.

[0021] In one embodiment, such as Figure 5As shown, the mounting plate 110 is provided with a first mounting hole 111 for mounting the belt misalignment detection switch 300.

[0022] The first mounting hole 111 is preferably circular.

[0023] A belt misalignment detection switch 300 is provided on the mounting plate 110. Specifically, a mounting base 310 is provided on the belt misalignment detection switch 300. In one embodiment, the outer diameter of the mounting base 310 is larger than the outer diameter of the first mounting hole 111.

[0024] The mounting plate 110 is provided with a second mounting hole 112, which is located outside the first mounting hole 111. Preferably, there are four second mounting holes 112 arranged in a square pattern. The mounting base 310 is mounted on the mounting plate 110 using bolts and nuts.

[0025] In one embodiment, a third mounting hole 113 is provided on the mounting plate 110, and the third mounting hole 113 is located outside the corresponding second mounting hole 112.

[0026] In one embodiment, a bend 114 is provided at the top of the mounting plate 110. An L-shaped belt misalignment switch mounting plate is used, allowing for easy up-and-down movement of the mounting plate when the position of the belt misalignment switch needs adjustment. When the position of the belt misalignment switch needs adjustment, the bend 114 allows for easy up-and-down movement of the mounting plate to adjust the height of the belt misalignment detection switch.

[0027] like Figure 6 As shown, the adjusting plate assembly 120 includes two adjusting plates 121, with connecting pieces 122 provided on the adjusting plates 121. The adjusting plates 121 are located on both sides of the belt misalignment detection switch 300.

[0028] like Figure 4 As shown, the side plate 210 of the belt conveyor housing 200 is provided with a belt misalignment detection switch mounting hole 211 and an adjustment hole 212. In one embodiment, the adjustment hole 212 is an oblong hole, and the adjustment hole 211 is vertically arranged on the side plate 210 of the belt conveyor housing. The oblong hole on the side plate ensures the effectiveness of the misalignment switch position after the belt is tensioned.

[0029] In one embodiment, there are four adjustment holes 212, which are respectively set at the four corners of the belt misalignment detection switch mounting hole 211.

[0030] In one embodiment, the adjusting plate 121 and the connector 122 are arranged perpendicularly; the number of connectors 122 on each adjusting plate 121 is two. The adjusting plate 121 is preferably elongated.

[0031] In one embodiment, the connector 122 is a welded stud, preferably an M8 welded stud. The locking member 123 is a nut. By using an adjustment plate assembly with two M8 welded studs, when the position of the misalignment switch needs to be adjusted, only the nuts need to be slightly loosened, without removing the welded studs, thus preventing the bolts from falling into the equipment during the adjustment process.

[0032] The installation process of the belt misalignment detection switch mounting structure is as follows: The adjusting plate 121 is located inside the side plate 210 of the belt conveyor housing 200; the mounting base 310 is located outside the side plate 210 of the belt conveyor housing 200. The connecting piece 121 passes through the adjusting hole 212 and the third mounting hole 113 on the mounting plate 100 in sequence, and is fitted with a locking piece 123. The vertical position of the connecting piece 122 in the adjusting hole 212 is adjusted, thereby adjusting the height of the belt misalignment detection switch 300 so that the belt misalignment detection switch matches the tensioned belt.

[0033] This invention effectively solves the problem of belt misalignment when the belt and the misalignment switch shift relative to each other during belt tensioning, by adjusting the position of the misalignment switch vertically. It ensures the switch remains effective regardless of tension displacement. Furthermore, the fixing bolts do not fall into the machine housing when adjusting the misalignment switch.

[0034] This invention can be applied to belt conveyors or air cushion conveyors in the bulk grain conveying industry.

[0035] The above embodiments are only for illustrating the technical features and concept of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made according to the spirit and implementation of this utility model should be covered within the protection scope of this utility model.
