Description

Technical Field

[0001] This utility model relates to the field of protection device technology, and in particular to a slip detection device. Background Technology

[0002] A slip detection detector is used to detect the running speed of the conveyor belt. When the conveyor belt's running speed is slower than the normal speed, it will issue a stop signal. Patent application number 202123071221.2 discloses a slip detection detector, which includes a housing with a connecting flange. A support cylinder is located on one side of the housing, and a main shaft is rotatably connected inside the support cylinder. A roller is located at one end of the main shaft. A reinforcing part is located at the lower part of the support cylinder near the housing end. Rotating shafts are located on both sides of the reinforcing part, and mounting plates are rotatably connected to the rotating shafts. Support plates are located on the mounting plates, and threaded holes are provided on both sides of the support plates. Adjustment devices are threaded into the threaded holes, and a rotating plate is rotatably connected to the top of the adjustment device. Hanging plates are located on both sides of the connecting flange, and a spring connects the hanging plates and the rotating plate, which can adjust the pressure between the roller and the conveyor belt. This application provides a different structure to achieve the function of adjusting the pressure between the roller and the conveyor belt. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a slip detection device in response to the above-mentioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a slip detector, including a housing, a support cylinder provided on one side of the housing, a main shaft rotatably connected inside the support cylinder, a roller provided at one end of the main shaft, and a base. A support plate is provided at the lower part of the housing, the lower end of the support plate is hinged to the base and the axis of the hinge axis is perpendicular to the axis of the main shaft. A push plate is provided on the side of the housing near the roller, and an elongated hole is provided on the push plate. The extension direction of the elongated hole is parallel to the axis of the main shaft. A stud perpendicular to the base is provided on the base. The stud passes through the elongated hole. A bottom nut is provided at the lower part of the stud. A spring is provided between the bottom nut and the push plate. A top nut is provided on the stud on the side of the push plate away from the spring.

[0005] To further optimize this technical solution, a washer is provided between the bottom nut and the spring.

[0006] To further optimize this technical solution, the base is provided with multiple mounting holes.

[0007] Compared with the prior art, the present invention has the following advantages: the support plate at the bottom of the housing is hinged to the base, the stud on the base passes through the elongated hole on the push plate on one side of the housing, the bottom nut is provided at the bottom of the stud, a spring is provided between the bottom nut and the push plate, and a top nut is provided on the stud on the side of the push plate away from the spring. The pressure between the roller and the belt can be adjusted by rotating the bottom nut, which is more convenient. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0012] Detailed implementation method: combined with Figure 1-2 As shown, a slip detection device includes a housing 1, which houses electrical components and circuitry. A support cylinder is located on one side of the housing 1, and a main shaft is rotatably connected within the support cylinder. A roller 11 is located at one end of the main shaft. The device also includes a base 2. A support plate 12 is located at the lower part of the housing 1. The lower end of the support plate 12 is hinged to the base 2, and the axis of the hinge is perpendicular to the axis of the main shaft (preferably, a convex plate is provided on the base 2, and two support plates 12 are located on opposite sides of the convex plate, with the lower ends of the support plates 12 hinged to the convex plate). The housing 1 has a support plate 12 located on the side near the roller 11. A push plate 13 is provided, which is parallel to the axis of the main shaft. The push plate 13 is provided with an elongated hole, the extension direction of which is parallel to the axis of the main shaft, and the elongated hole is symmetrical about the symmetrical plane of the housing 1. A stud 22 perpendicular to the base 2 is provided, which passes through the elongated hole. A bottom nut 25 is provided at the lower part of the stud 22, which is located between the base 2 and the push plate 13. A spring 24 is provided between the bottom nut 25 and the push plate 13. A top nut 23 is provided on the side of the push plate 13 away from the spring 24 on the stud 22, and the spring 24 is in a compressed state.

[0013] Furthermore, a washer is provided between the bottom nut 25 and the spring 24.

[0014] Furthermore, the base 2 is provided with a plurality of mounting holes 21. The base 2 is rectangular, and there are four mounting holes 21 located at the four corners of the base 2.

[0015] During installation, base 2 is parallel to the horizontal plane and can be installed on the crossbeam below the (belt conveyor) belt. After installation, combine... Figure 1 As shown, rotate the top nut 23 to move it upwards until the roller 11 presses against the bottom surface of the conveyor belt. Then, move the top nut 23 upwards a certain distance to ensure that the roller 11 reliably presses against the bottom surface of the conveyor belt. Afterwards, rotate the bottom nut 25 to move it up or down to adjust the pressure between the roller 11 and the conveyor belt. This structure, with only one spring 24, makes pressure adjustment relatively convenient. Furthermore, during installation, because the top nut 23 can be rotated downwards a certain distance, the roller 11 does not contact the conveyor belt during the process of fixing the base 2 to the crossbeam, making installation even easier. After installation, move the top nut 23 upwards again.
