Description

Technical Field

[0001] This utility model relates to the field of protection switch technology, and in particular to a novel slippage detector. Background Technology

[0002] The working principle of a belt conveyor is mainly that the drive roller drives the belt. If the belt slips between the belt and the drive roller, it may lead to a serious accident. Therefore, it is necessary to install a slip detection device on the belt conveyor. Existing slip detection technologies, such as patent application number 202123071221.2 entitled "A Slip Detector" and patent application number 202321738402.2 entitled "A Belt Slip Detection Device", involve placing a spring between the base and the housing to create pressure between the roller and the bottom surface of the belt on the belt conveyor. This allows the roller to rotate around an axis perpendicular to its axis. However, this method results in greater pressure on the side of the roller away from the housing and less pressure on the side closer to the housing. After prolonged use, this leads to uneven wear on the two sides of the roller, resulting in unequal diameters. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a new type of slip detection device to address 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 novel slip detector, comprising a base and a housing, a support cylinder is provided at one end of the housing, a main shaft is rotatably connected inside the support cylinder, a roller is provided on the main shaft, a first ear plate is provided on the lower side of the housing, a first shaft hole is provided on the first ear plate, the axis of the first shaft hole is parallel to the axis of the roller, a second ear plate is provided on the base, a second shaft hole is provided on the second ear plate, a pin passes through both the first shaft hole and the second shaft hole, and one end of an elastic band is fixed to the side of the housing and the other end is fixed to the base.

[0005] To further optimize this technical solution, mounting holes are provided at all four corners of the base.

[0006] To further optimize this technical solution, the number of both the first ear plate and the second ear plate is two.

[0007] Compared with the prior art, the present invention has the following advantages: a first ear plate is provided on the lower side of the shell, and a first shaft hole is provided on the first ear plate with an axis parallel to the axis of the roller. A second ear plate is provided on the base, and a second shaft hole is provided on the second ear plate. The pin passes through both the first shaft hole and the second shaft hole, and the axis of the pin is also parallel to the axis of the roller. Thus, the pressure between the roller and the conveyor belt is the same on both sides of the roller that are close to the base and the side that is far from the base, avoiding the situation where the diameters are not equal due to different wear on both sides of the roller.

[0010] 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.

[0011] Detailed implementation method: combined with Figure 1 As shown, a novel slip detection device includes a base 1 and a housing 3. A support cylinder 4 is provided at one end of the housing 3, and a main shaft is rotatably connected inside the support cylinder 4. Electrical components are provided inside the housing 3 to detect the rotational speed of the main shaft and are connected to an external control box via wires. A roller 5 is provided on the main shaft. A first ear plate is provided on the lower side of the housing 3, and the plane of the first ear plate is perpendicular to the axis of the roller 5. A first shaft hole is provided on the first ear plate, and the axis of the first shaft hole is parallel to the axis of the roller 5. A second ear plate is provided on the base 1, and a second shaft hole is provided on the second ear plate. A pin passes through both the first shaft hole and the second shaft hole, so that the housing 3 is hinged to the base 1. One end of an elastic band 2 is fixed to the side of the housing 3 (rather than both ends) and the other end is fixed to the base 1. Preferably, a certain length of the elastic band 2 is wrapped around the side of the housing 3, so that the elastic band 2 has a large length. The longer the elastic band 2 is, the smaller the change in tension of the elastic band 2 when the housing 3 rotates around the pin.

[0012] Furthermore, mounting holes 11 are provided at all four corners of the base 1 to facilitate the installation of the base 1 on the belt conveyor.

[0013] Furthermore, there are two of each of the first and second ear plates, and the two first ear plates are located near both ends of the housing 3.

[0014] When using, combine Figure 1 As shown, the base 1 is mounted on the belt conveyor, and the axis of the roller 5 is located at... Figure 1On the front side of the central pin shaft axis (the side where the elastic band 2 is fixed on the base 1 is the front side), under the tension of the elastic band 2, the roller 5 contacts the bottom surface of the conveyor belt. The axis of the roller 5 is perpendicular to the running direction of the conveyor belt and parallel to the bottom surface of the conveyor belt. Thus, the pressure between the roller 5 and the conveyor belt is the same on both sides of the roller 5 that are close to the base 1 and the side that is far from the base 1, which avoids the situation where the diameters of the roller 5 are not equal due to the different wear on both sides mentioned above.
