Due to the characteristics of the transported gangue, such as high hardness and large flow rate, the chute body faces serious wear problems. The existing gangue chutes in practical applications have the following significant defects: High maintenance cost: The original chute needs to be maintained 5-8 times per month, each maintenance takes 4-6 hours, and the labor and material cost for a single maintenance is about 2000 yuan. Outstanding safety risks: The maintenance operation requires high-altitude operation, and there are potential safety hazards such as the fall of operators and mechanical injuries during this process. Moreover, the shutdown for maintenance will affect the continuity of production, thereby reducing the production efficiency.

Detailed Implementation

[0012] See attached document Figures 1 to 3 This utility model provides a modular, weld-free chute wear-resistant liner quick-replacement structure, including a chute 1, a wear-resistant plate 2 detachably connected to the inner side of the chute 1, a hook on the wear-resistant plate 2, and a crossbar 201 for use with the hook inside the chute 1. The hook is U-shaped and includes a first connecting part 202 connected to the wear-resistant plate 2. One end of the first connecting part 202 is connected to the wear-resistant plate 2, and the other end of the first connecting part 202 is provided with a transition connecting plate 203 connected to it. One end of the transition connecting plate 203 is connected to the first connecting plate 202, and the other end of the transition connecting plate 203 is connected to a second connecting plate 204. The first connecting plate 202, the transition connecting plate 203, and the second connecting plate 204 form a one-way open receiving space, and the crossbar 201 is disposed in the receiving space.

[0013] The wear-resistant plate is made of NM400 wear-resistant steel (hardness ≥400HB).

[0014] This invention, through the above structure, ensures that when high-hardness materials impact the inner side of the chute 1, they first contact the wear-resistant plate 2, preventing direct contact between the high-hardness material and the chute 1, thus avoiding excessive wear on the chute 1. Simultaneously, hooks are designed on the wear-resistant plate 2, and a crossbar 201 is installed on the inner side of the chute 1. The wear-resistant plate 2 is connected to the chute 1 by hooking the crossbar 201. This avoids the use of welding for connection, reducing the workload of workers and lowering the risks associated with working at heights.

[0015] This utility model, through the above structure, reduces the transformation cost, with the transformation cost of a single chute being approximately 15,000 yuan, a reduction of more than 80% compared to the traditional overall replacement solution; annual maintenance cost savings: reduced from 48,000 yuan to 8,000 yuan, a saving of 40,000 yuan; increased production efficiency: reduced downtime by 80 hours per year, which, based on an hourly processing capacity of 500 tons of coal and a profit of 50 yuan per ton of coal, translates to an annual increase in benefits of 200,000 yuan; facilitates safety management: reduced the frequency of high-altitude operations by 75%, reducing downtime losses due to safety accidents by approximately 20,000 yuan per year; simple operation, wear-resistant plates can be disassembled and replaced without welding, and a single person can complete the replacement within 10 minutes without the need for professional tools; Preferred, see Figure 4 and Figure 5The chute 1 has multiple limiting holes 205 on its bottom, and the wear-resistant plate 2 has multiple corresponding positioning pins 206. The positioning pins 206 cooperate with the limiting holes 205. Each limiting hole 205 has a misalignment groove 213 on one side, which communicates with the limiting hole 205. The hook includes two interconnected third connecting plates 211 and fourth connecting plates 212. One end of the third connecting plate 211 is connected to the wear-resistant plate 2, and the other end is connected to the fourth connecting plate 212. The crossbar 201 is positioned between the fourth connecting plate 212 and the wear-resistant plate 2. The left and right width of the misalignment groove 213 is not less than the sum of the left and right widths of the third connecting plate 211 and the fourth connecting plate 212.

[0016] With the above structure, in use, the positioning pin 206 is first positioned inside the misalignment groove 213. Since the left and right width of the misalignment groove 213 is not less than the sum of the left and right widths of the third connecting plate 211 and the fourth connecting plate 212, when the positioning pin 206 contacts the bottom of the misalignment groove 213, the crossbar 201 can be positioned between the fourth connecting plate 212 and the wear-resistant plate 2, which facilitates the placement of the crossbar 201 between the fourth connecting plate 212 and the wear-resistant plate 2, thus improving the installation efficiency of the wear-resistant plate 2. The misalignment groove 213 is connected to the limiting hole 205. Therefore, when the positioning pin 206 moves downward, it can move from the inside of the misalignment groove 213 to the inside of the limiting hole 205. At this time, the crossbar 201 moves in the direction closer to the third connecting plate 211, so that the positioning pin 206 is inserted into the inside of the limiting hole 205. The limiting hole 205 can restrict the four degrees of freedom of the positioning pin 206 (up, down, forward, backward). The fourth connecting plate 212 can restrict the wear-resistant plate 2 from moving away from the chute 1, so that the wear-resistant plate 2 can be reliably connected to the wear-resistant plate 2.

[0017] Preferred, see Figure 6 and Figure 7 An elastic component is provided inside the limiting hole 205. The elastic component can apply pre-pressure to the positioning pin 206, so that the crossbar 201 can contact the fourth connecting plate 212. The elastic component includes an elastic sleeve 207. A movable plunger 208 is provided inside the elastic sleeve 207 and slides relative to it. The movable plunger 208 can contact the positioning pin 206. A spring 210 is provided between the movable plunger 208 and the elastic sleeve 207. With the above structure, after the wear-resistant plate 2 is installed, the positioning pin 206 contacts the movable plunger 208 and applies a certain pressure to the movable plunger 208, so that the spring 210 is compressed. The elastic force of the spring 210 keeps the movable plunger 208 and the positioning pin 206 in contact at all times. That is, the wear-resistant plate 2 is subjected to a force away from the chute 1, so that the crossbar 201 is always in contact with the fourth connecting plate 212. To prevent the wear-resistant plate 2 from shaking relative to the fourth connecting plate 212 when the material impacts the wear-resistant plate 2, thereby affecting the reliability of the connection between the fourth connecting plate 212 and the third connecting plate 211.

[0018] This invention, through the above structure, features a wear-resistant plate detachably connected to the inner side of the chute, with hooks on the wear-resistant plate and a crossbar inside the chute that works in conjunction with the hooks. The wear-resistant plate is connected to the chute by hooking the crossbar. This avoids welding, reducing the workload of workers and the risks associated with working at heights. It also reduces maintenance costs, minimizes downtime for maintenance, and improves overall work efficiency.

[0019] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
