Description

Technical Field

[0001] This utility model belongs to the field of coal mine coal conveying equipment monitoring technology, specifically relating to a longitudinal tear monitoring swing arm for belt conveyors. Background Technology

[0002] In the coal mining industry's production and transportation system, the coal conveyor belt is a core conveying equipment, and its operating status directly determines the efficiency of coal transportation and the continuity of the production process. Due to the harsh working environment in coal mines, the coal conveyor belt is exposed to complex conditions such as dust, moisture, and heavy impact for a long time, which makes the conveyor belt prone to surface defects such as wear, tear, and cracks. If such defects are not detected and dealt with in time, they will not only lead to a decrease in the conveyor belt's conveying capacity, but may also cause sudden failures such as conveyor belt breakage, resulting in equipment downtime for maintenance, increased maintenance costs and downtime, and even threatening the personal safety of on-site workers.

[0003] Therefore, timely and accurate detection of surface defects in coal conveyor belts is crucial. Effective defect detection helps maintenance personnel identify potential equipment problems before malfunctions occur, allowing for preventative and maintenance measures to be taken in advance. This extends equipment lifespan, ensures stable operation, reduces production interruptions, lowers maintenance costs, ensures the continuity and reliability of coal transportation, and further enhances the economic efficiency and safety of the entire coal mine production system. Currently, longitudinal tear detectors are commonly used to detect longitudinal tear defects in coal conveyor belts, with the core component being a longitudinal tear monitoring pendulum. Existing longitudinal tear monitoring pendulums typically consist of a horizontal plate, a vertical plate, an L-shaped frame, fasteners, a concave frame, and the pendulum body. The pendulum body is fixedly mounted on the concave frame, and its installation height is fixed and cannot be adjusted. However, in actual coal mine production scenarios, coal conveyor belts come in various models, and the height of the conveyor belts differs between these models. The existing fixed-height longitudinal tear monitoring pendulums cannot adapt to conveyor belts of different heights, resulting in poor versatility and failing to meet the longitudinal tear detection requirements of coal conveyor belts under different operating conditions. This increases equipment procurement and maintenance costs, limiting its widespread application in the coal mining industry. Utility Model Content

[0014] Example 1 Please see Figures 1-6 This is the first embodiment of the present invention, which provides a longitudinal tear monitoring swing arm for a belt conveyor, including... The two symmetrically arranged L-shaped frames 3 ensure more even force distribution on the entire monitoring swing arm, preventing excessive force on one side from causing component deformation or tilting, thus improving the overall stability of the device during belt conveyor operation. Simultaneously, they provide a symmetrical and stable support foundation for the subsequent installation of components such as the concave frame 7 and the swing arm body 6, ensuring that the swing arm body 6 always maintains a precise alignment with the coal conveyor belt, guaranteeing monitoring accuracy. A fastener 5 is installed on the top of each L-shaped frame 3, providing a reliable mounting surface for the concave frame 7. The concave frame 7, which is rotatably mounted on any of the fasteners 5, has a swing arm body 6 detachably mounted on both concave frames 7, thus enabling the addition of the swing arm body 6 and ensuring the effectiveness of longitudinal tear monitoring. When the swing arm body 6 is worn or damaged and needs to be replaced, it is not necessary to disassemble the entire concave frame 7 or L-shaped frame 3. Only the old swing arm body 6 needs to be removed and the new one installed, which greatly simplifies the maintenance and replacement process, reduces equipment downtime for maintenance, and lowers maintenance costs. The adjusting and stabilizing components include a ferromagnetic metal fastening cylinder 8 installed at the bottom of the concave frame 7. The ferromagnetic metal fastening cylinder 8 provides a stable receiving space for the lower part of the swing arm body 6, providing initial positioning and support. Simultaneously, the ferromagnetic material can cooperate with the subsequent magnet column 93 and magnet cylinder 92 to achieve adsorption and fixation, providing the basic conditions for height adjustment and stable fixation of the swing arm body 6. Furthermore, the ferromagnetic metal material has high strength and good wear resistance, extending the service life of the fastening cylinder. An opening is provided at the top of the concave frame 7 for the swing arm body 6 to pass through. The lower part of the swing arm body 6 can be inserted into the interior of the ferromagnetic metal fastening cylinder 8. Through the cooperation of these two components, the height of the swing arm body 6 can be adjusted according to the input... To meet the varying height requirements of coal conveyor belts, the swing arm body 6 is adjusted to the appropriate position and then fixed, satisfying the adaptation needs of coal conveyor belts of different heights and solving the problem that existing devices can only adapt to coal conveyor belts of a single height. A through hole is made on the side surface of the ferromagnetic metal fastening cylinder 8, and a threaded frame 82 is installed on the side surface of the ferromagnetic metal fastening cylinder 8 and located outside the through hole. A threaded abutment 10 is threadedly connected to the threaded frame 82, and the threaded abutment 10 can abut against the side surface of the swing arm body 6. The threaded frame 82 and the threaded abutment 10 form a threaded engagement. By rotating the threaded abutment 10, it can be moved axially along the threaded frame 82, thereby controlling the clamping force of the threaded abutment 10 on the swing arm body 6. The operation is simple and the fixing effect is reliable. The tightening operation can be completed by rotating the threaded abutment 10, and the adjustment process is convenient and efficient.

[0015] In this embodiment, preferably, a limiting frame 72 is also installed on the top of the concave frame 7, and the limiting frame 72 is located outside the opening. It can further restrict the lateral movement of the swing arm body 6, prevent the swing arm body 6 from shifting laterally due to the impact of the coal conveyor belt during operation, and ensure that the swing arm body 6 always stays in the correct monitoring position. At the same time, the limiting frame 72 can also play a certain protective role for the swing arm body 6, reducing the interference of external debris on the joint between the swing arm body 6 and the opening.

[0016] In this embodiment, preferably, it also includes symmetrically arranged slots 81 on the ferromagnetic metal fastening cylinder 8. The symmetrically arranged slots 81 provide an installation and movement channel for the support rod 91, so that the support rod 91 can pass through the slot 81 and support the bottom end of the swing rod body 6. The support rod 91 that passes through the slot 81 and supports the bottom end of the swing rod body 6 can provide additional support force for the swing rod body 6, avoid the swing rod body 6 relying solely on the lateral clamping force of the threaded abutment 10 for fixation, and reduce the deformation of the swing rod body 6 caused by long-term stress.

[0017] In this embodiment, preferably, a magnetic post 93 is also provided at one end of the support rod 91, and the magnetic post 93 can be attracted and connected to the ferromagnetic metal fastening cylinder 8, which can fix one end of the support rod 91 to the ferromagnetic metal fastening cylinder 8, ensuring that the support rod 91 supports the swing arm body 6 effectively at all times; at the same time, the magnetic attraction connection method is simple to operate. When it is necessary to adjust the position of the support rod 91, it is only necessary to overcome the attraction force to move the support rod 91 without disassembling other parts.

[0018] In this embodiment, preferably, it also includes a vertical plate 2 installed on the side surface of any one of the L-shaped frames 3, and a horizontal plate 1 installed on the inner side of the two vertical plates 2, to prevent the L-shaped frame 3 from deforming due to long-term bearing of the weight of components such as the concave frame 7 and the swing arm body 6; at the same time, the vertical plate 2 can also provide a flat and stable connection surface for the subsequent installation of the horizontal plate 1, ensuring the connection between the horizontal plate 1 and the two L-shaped frames 3, thereby improving the structural stability of the entire device.

[0019] In this embodiment, preferably, it also includes a U-shaped frame 4 that is detachably connected to the L-shaped frame 3, and the corners of the U-shaped frame 4 are arc-shaped. The U-shaped frame 4 can strengthen the support of the L-shaped frame 3 and improve the deformation resistance of the L-shaped frame 3. At the same time, the arc-shaped corner design can prevent personnel from being scratched or equipment from being bumped due to sharp corners during the installation and use of the U-shaped frame 4, thereby improving the safety of the device. The side surface of the concave frame 7 is provided with an extension shaft 71 to ensure the smooth rotation of the concave frame 7.

[0020] Example 2 Please see Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that: It also includes a magnetic cylinder 92 sleeved on the support rod 91, and the magnetic cylinder 92 can be attracted and connected to the ferromagnetic metal fastening cylinder 8, further improving the stability of the support rod 91 in the slot 81, preventing the support rod 91 from moving along the length direction of the slot 81, and ensuring that the support rod 91 is always in the optimal position of supporting the swing arm body 6.

[0021] The working principle and usage process of this utility model are as follows: Insert the swing arm body 6 into the ferromagnetic metal fastening cylinder 8 through the through-hole, and adjust the insertion depth according to the height of the coal conveyor belt to ensure that the swing arm body 6 is close to the coal conveyor belt. Tighten the threaded abutment 10 to press against the rocker arm body 6 to fix it in place, ensuring that the rocker arm body 6 is vertical and does not tilt. Pass the support rod 91 through the slot 81 to support the bottom of the swing rod body 6, and use the magnet post 93 and the magnet cylinder 92 to attract the ferromagnetic metal fastening cylinder 8 to fix the support rod 91.
