Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation equipment technology, and in particular to an adjustable mine tear protector. Background Technology

[0002] As a key continuous transportation equipment in underground coal mine operations, the safe and stable operation of belt conveyors is directly related to production efficiency and economic benefits. Belt tearing is one of the most serious failures in the operation of conveyors. It not only causes damage to the belt itself, resulting in huge direct economic losses, but also causes material leakage, equipment shutdown, and even safety accidents. To prevent such risks, belt tear protectors are widely used along the conveyor system to monitor the belt status in real time and promptly alarm and shut down the machine in the early stage of tearing to prevent the accident from escalating.

[0003] Currently, belt tear protectors used on-site are generally suspended and installed using steel wire ropes. The length of the steel wire ropes is fixed, and the height cannot be quickly and accurately adjusted according to the on-site working conditions, resulting in poor detection sensitivity and easy false alarms or missed alarms. In addition, the connection points between the steel wire rope and the protector and the frame are usually simple rope clips or hooks. In the working environment of continuous vibration of the belt conveyor, the connection is very easy to loosen, causing the device to fall off or shift, resulting in a high frequency of damage.

[0004] Therefore, to address the aforementioned issues, an adjustable mine tear protector device can be designed. This device utilizes a steel structure welded into a rectangular groove to house the tear protector, ensuring stable installation. Bolts and nuts are used to adjust the height of the rectangular groove and rigidly fix it in place. This improves the accuracy of detection sensitivity adjustment, effectively reduces the probability of false alarms and missed alarms, decreases equipment failure rates, significantly increases work efficiency, and saves labor costs, providing reliable technical support for the safety management of transportation systems. Utility Model Content

[0005] To overcome the problems of traditional belt tear protectors being generally suspended by steel wire ropes, which makes it inconvenient to adjust the height of the protector body and the connection between the steel wire rope and the protector body is not secure, resulting in the protector frequently falling off and being damaged frequently.

[0006] The technical solution of this utility model is as follows: an adjustable mine tear protector, including a fixed frame, a placement frame set above the fixed frame, and four sets of mounting bolts. The four sets of mounting bolts all pass through the fixed frame. Each set of mounting bolts is threaded with two sets of fixing nuts on its periphery. The two sets of fixing nuts are located on the upper and lower sides of the fixed frame, respectively. Each set of mounting bolts is threaded with an adjusting nut on its periphery. The adjusting nut is located below the fixing nut.

[0007] Preferably, the mounting bolts and adjusting nuts can be used to fix the mounting frame in a suitable position on the conveyor frame. The installation height of the mounting frame can be adjusted by rotating the adjusting nuts, thereby adapting to the installation height requirements of different working conditions on site, thus providing greater flexibility. Two sets of fixing nuts can be used to securely connect the mounting bolts and the mounting frame. The protective device can be installed and placed using a placement frame. The placement frame, which is made of steel structure, can effectively ensure the stability of the protective device body during installation.

[0008] Preferably, the placement frame is fixedly installed on the upper end of the fixing frame by welding.

[0009] Preferably, the inner wall of the frame is provided with a rubber pad layer.

[0010] Preferably, a connecting block is fixedly installed at the lower end of the frame, a hinge shaft is fixedly installed inside the connecting block, and two sets of fixing plates are fixedly installed inside the fixing frame. The hinge shaft passes through the two sets of fixing plates and is rotatably connected to them.

[0011] Preferably, one end of the hinge shaft has a through insertion hole, and the surface of the fixing plate on the corresponding side has multiple sets of reserved holes evenly arranged around the axis of the hinge shaft.

[0012] Preferably, the socket is provided with a pin inside, with one end of the pin located inside one of the pre-drilled holes.

[0013] Preferably, a magnetic ring is fixedly installed around the pin, and the magnetic ring is magnetically connected to the fixing plate.

[0014] The beneficial effects of this utility model are: The placement frame, welded from steel, allows for stable placement of the protector body. Installed on top of the fixed frame, the frame, through the coordinated action of mounting bolts and adjusting nuts, ensures precise positioning and secure installation of the fixed frame on the conveyor frame. The installation height of the fixed frame can be continuously adjusted by rotating the adjusting nuts, adapting to different on-site conditions and significantly improving installation flexibility. Two sets of fixing nuts form a bidirectional locking structure, effectively preventing loosening between the mounting bolts and the fixed frame, further ensuring the stability of the protector body installation.

[0016] Example 1 The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1 and Figure 2 This utility model provides an embodiment of an adjustable mine tear protector, including a fixed frame 1, a placement frame 3 disposed above the fixed frame 1, and four sets of mounting bolts 2. All four sets of mounting bolts 2 penetrate the fixed frame 1. Each set of mounting bolts 2 has two sets of fixing nuts 202 threadedly connected to its periphery. The two sets of fixing nuts 202 are located on the upper and lower sides of the fixed frame 1, respectively. Each set of mounting bolts 2 also has a set of adjusting nuts 201 threadedly connected to its periphery, located below the fixing nuts 202. By using the mounting bolts 2 and adjusting nuts 201, the fixed frame 1 can be fixedly installed at a suitable position on the conveyor frame. By rotating the adjusting nuts 201, the installation height of the fixed frame 1 can be adjusted to adapt to different on-site working conditions, providing greater flexibility. The two sets of fixing nuts 202 provide a stable connection between the mounting bolts 2 and the fixed frame 1. The placement frame 3 allows for the installation and placement of the protector. The steel structure of the placement frame 3 effectively ensures the stability of the protector's installation.

[0018] Please see Figure 1 In this embodiment, the placement frame 3 is fixedly installed on the upper end of the fixing frame 1 by welding, forming a stable rigid connection structure to ensure the installation reliability of the protector body under complex working conditions; the inner cavity wall of the placement frame 3 is provided with a rubber pad layer 301, which is made of a highly wear-resistant and anti-aging elastic material, which can effectively absorb vibration and shock and protect the tear protector shell from mechanical damage.

[0019] Example 2 Please see Figure 3 , Figure 4 and Figure 5 This utility model provides another embodiment, which differs from embodiment 1 in that, in this embodiment, a connecting block 401 is fixedly installed at the lower end of the placement frame 3, a hinge shaft 403 is fixedly installed inside the connecting block 401, and two sets of fixing plates 402 are fixedly installed inside the fixing frame 1. The hinge shaft 403 passes through the two sets of fixing plates 402 and is rotatably connected to them, forming an adjustable-angle rotating pair structure; one end of the hinge shaft 403 is provided with a through insertion hole 501, and the surface of the fixing plate 402 on the corresponding side is provided with multiple sets of reserved holes 502 evenly arranged around the axis of the hinge shaft 403. A pin 503 is provided inside the insertion hole 501, and one end of the pin 503 is located in one of them. Inside the pre-drilled holes 502, a magnetic ring 504 is fixedly installed around the pin 503. The magnetic ring 504 is magnetically connected to the fixing plate 402. The pin 503 passes through the hinge shaft 403 and can lock the hinge shaft 403 by cooperating with the pre-drilled holes 502. Multiple sets of pre-drilled holes 502 form a multi-level angle positioning structure. When the pin 503 is inserted into the insertion hole 501 and one of the pre-drilled holes 502, the magnetic ring 504 is magnetically connected to the fixing plate 402, which can effectively prevent the pin 503 from accidentally coming out. This allows for stable adjustment of the installation angle of the placement frame 3, further improving the applicability of the protector body and adapting to the monitoring and protection of conveyor belts at different angles.

[0020] Through the above steps, the fixed frame 1 supports and installs the placement frame 3. The placement frame 3, which is welded from steel structure, can stably install the protector. The coordinated cooperation of the mounting bolts 2 and the adjusting nut 201 can achieve precise positioning and stable installation of the fixed frame 1 on the conveyor frame. By rotating the adjusting nut 201, the installation height of the fixed frame 1 can be continuously adjusted, thereby adapting to the installation height requirements of different working conditions on site and significantly improving installation flexibility. This solves the problem that traditional belt tear protectors are generally installed by hanging with steel wire ropes, which makes it inconvenient to adjust the height of the protector body, and the connection between the steel wire rope and the protector body is not firm, often resulting in the protector falling off and high damage frequency.

[0021] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
