Description

Technical Field

[0001] The utility model belongs to the field of belt transportation, in particular to a belt deviation sensor mounting bracket. Background Art

[0002] Belt conveyors are widely used to transport goods underground in coal mines. Belt deviation is the most common fault during operation. If a belt conveyor deviates during production and transportation, it will increase resistance to the belt's operation, leading to accidents such as belt winding, belt pulling, belt breakage, and motor burnout. In serious cases, it may even cause a fire. It can also cause coal to spill along the conveyor belt, impacting the environment and increasing the workload for employees. Article 374, Paragraph 2 of the "Coal Mine Safety Regulations" (2022) stipulates that roller-driven belt conveyors must be equipped with protective devices to prevent slipping, deviation, coal accumulation, and tearing. Temperature and smoke monitoring devices and automatic sprinklers must also be installed. The Ministry of Emergency Management also stipulates that "the failure of conveyor belt anti-slip, deviation, coal accumulation protection devices, or temperature and smoke monitoring devices, constitutes a major accident hazard in coal mines." The function of the anti-deviation protection device is to delay and automatically shut down the conveyor belt if the conveyor belt deviates. Currently, deviation sensors are commonly used to detect conveyor belt deviation. The installation requirements for conveyor belt deviation protection are as follows: Belt conveyor deviation sensors should be used in pairs and installed 10-15 meters from the conveyor's drive roller and the tail coal drop point. The deviation sensors should be fixed to the conveyor frame or longitudinal beam, with the sensor's axial centerline perpendicular to the belt edge. When the belt deviates, the sensor should contact the appropriate position of the deviation switch, with a deviation margin of less than 20mm. The deviation sensors lack a fixed mounting bracket, and various installation methods are used. Some locations even use wire ties at varying heights, making them difficult to adjust to the conveyor's actual conditions. This results in poor adjustment and fails to meet regulatory requirements. This ineffectiveness in preventing deviation poses a safety hazard. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] The words "vertical", "horizontal", "longitudinal", "up", "down", "left", "right" and so on used in this utility model to indicate directions are based on the attached Figure 7 The orientation or positional relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0021] Conveyor belt deviation sensor mounting bracket, such as Figure 1 As shown, the yaw sensor 1 includes a plate-type mounting base 11 at the bottom and a sensing portion 12 on the plate-type mounting base 11. Three circular mounting holes 13 are respectively formed on the outer periphery of the plate-type mounting base 11. The three circular mounting holes 13 are distributed in an equilateral triangle. The yaw sensor 1 includes a forward frame body A and a reverse frame body B.

[0022] like Figure 2 、 3 , 4 and 5, the forward frame body A and the reverse frame body B each include a mounting plate 2 and a fixed plate 3; three strip mounting holes 21 are provided on the mounting plate 2, the strip mounting holes 21 correspond to the circular mounting holes 13 one by one, and the three strip mounting holes 21 form an equilateral triangle along the center line of the length direction, that is, the angle between the two strip mounting holes 21 is 60°; the fixed plate 3 is perpendicular to the mounting plate 2, and one end thereof is fixedly connected to the edge of the mounting plate 2; a circular through hole 31 is respectively provided at both ends of the fixed plate 3, and the spacing between the circular through holes 31 at both ends of the fixed plate 3 is equal to the spacing between the two adjacent connecting holes 51 on the conveyor belt bracket 5; the forward frame body A and the reverse frame body B are mirror images.

[0023] The present utility model discloses a mounting plate 2 for a conveyor belt deviation sensor, which supports the weight of the deviation sensor 1. The mounting plate 2 does not need to be too thick, as it is prone to deformation if too thin. The mounting plate 2 is typically 3-5 mm thick and is typically made of 4 mm thick iron plate. To correspond to the three circular mounting holes 13 on the deviation sensor 1, the mounting plate 2 is provided with three strip-shaped mounting holes 2. The arrangement of these elongated strip-shaped mounting holes 2 facilitates the insertion of bolts through the strip-shaped mounting holes 2 and the corresponding circular mounting holes 13 to secure the deviation sensor 1 to the mounting plate 2. Furthermore, it creates space for the deviation sensor 1 to be rotated and adjusted on the mounting plate 2, thereby improving the installation accuracy of the deviation sensor 1.

[0024] The mounting plate 2 may be square, etc. In order to minimize the size of the mounting plate 2 and reduce its weight, preferably, the mounting plate 2 is triangular.

[0025] The fixing plate 3 mainly plays a fixing role and often needs to be adjusted, so it is easy to deform if it is too thin. The best thickness is 4-5mm, and it is usually made of 5mm thick iron plate.

[0026] The forward frame body A and the reverse frame body B form a pair. Each set of conveyor belt deviation sensor mounting brackets contains one forward frame body A and one reverse frame body B. The forward frame body A and reverse frame body B are mirror images, meaning that when the forward frame body A and reverse frame body B are installed on the left and right sides of the same conveyor belt cross-section, they are directly opposite each other. This arrangement ensures that the belt conveyor deviation sensors 1 should be used in pairs.

[0027] In order to facilitate fixing the fixing plate 3 to the conveyor belt bracket 5 on both sides of the conveyor belt, preferably, as shown in FIG. Figure 6 As shown, a fixed plate 3 is equipped with a U-shaped clip 4. The U-shaped clip 4 includes side bars 41 on both sides and a connecting bar 42 in the middle. The spacing between the side bars 41 matches the spacing between the two connecting holes 51 on the fixed plate 3. The ends of the side bars 41 away from the connecting bar 42 are provided with external threads, which are equipped with flat washers, spring washers, and nuts. The U-shaped clip 4 is made of round steel.

[0028] The specific steps for installing the conveyor belt deviation sensor 1 using the conveyor belt deviation sensor mounting bracket disclosed in the present utility model are as follows:

[0029] The first step, such as Figure 7 and Figure 8As shown, the fixing plate 3 of the forward frame body A is attached to the inner side of the conveyor belt bracket 5 on one side of the conveyor belt, and the U-shaped clip 4 is passed through the connecting hole 51 on the fixing plate 3 and the connecting hole 51 on the conveyor belt bracket 5 at the same time, and then a flat washer and a spring washer are installed, and the nut is tightened to achieve the installation of the forward frame body A to the conveyor belt bracket 5 on one side of the conveyor belt; similarly, the reverse frame body B is installed to the conveyor belt bracket 5 on the other side of the conveyor belt;

[0030] The second step is to place the running deviation sensor 1 on the mounting plate. First, insert the bolts into the strip mounting hole 21 near the side of the fixed plate 3, and then insert the bolts into the other two strip mounting holes 21 to facilitate adjusting the angle of the running deviation sensor 1 to meet the installation requirements. That is, the axial center line of the running deviation sensor 1 is perpendicular to the edge of the tape, and the running deviation margin is less than 20 mm. Finally, tighten the bolts.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
