Description

Technical Field

[0001] This utility model relates to the field of underground engineering structure protection technology, and in particular to a shock-absorbing and vibration-damping wall protection device for well chute walls. Background Technology

[0002] During ore chute loading, the impact and abrasion of the ore flow on the ore pass makes the protection of the pass wall extremely important. Existing protection technologies include metal liners, which are wear-resistant and high-strength, but suffer from high cost and noise; shotcrete on the pass wall is efficient and inexpensive, but not wear-resistant; traditional pass wall protection measures such as buffer platforms and chutes have drawbacks such as large space requirements and low transport efficiency. Complete spherical rock-breaking devices have a small contact area with the pass wall, and the device continuously impacts one or a few points, leading to structural damage over long-term operation. Therefore, it is crucial to provide an easy-to-maintain pass wall anti-impact and vibration-damping protective device that reduces pass wall damage. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-impact and shock-absorbing wall protection device for ore chute, so as to solve the problems existing in the prior art, effectively reduce the impact and wear of ore and rock on the ore chute wall, and facilitate replacement and maintenance.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides an anti-impact and shock-absorbing wall protection device for a ore chute, comprising a contact body and a connecting member; the contact body is used to be disposed on the inner wall of the ore chute opposite to the inclined chute; the contact body includes multiple protrusions; the protruding side of each protrusion is located on the same side and faces the inclined chute; the other side of each protrusion can be in surface contact with the inner wall of the ore chute; the connecting member is used to connect the protrusions, and the connecting member is detachably fixed to the inner wall of the ore chute.

[0005] Preferably, a buffer pad is fixedly provided on the inner wall side of the contact body near the well wall, and the buffer pad is in surface contact with each of the protrusions and the inner wall of the well wall.

[0006] Preferably, the connecting member is internally connected to each of the protrusions, and each pair of adjacent protrusions are in close contact.

[0007] Preferably, the connecting member is a chain or rope.

[0008] Preferably, the convex body is a hemisphere.

[0009] Preferably, the protrusion is made of ferrous material, steel, impact-resistant and wear-resistant alloy, or non-metallic material.

[0010] Preferably, the cushioning layer is made of rubber, ultra-high molecular weight polyethylene, ethylene-vinyl acetate, or a foamed composite material.

[0011] Preferably, the protrusion is provided with a connecting hole for the connecting member to pass through and connect.

[0012] The present invention achieves the following technical advantages over the prior art: The impact-resistant and shock-absorbing wall protection device for ore chutes provided by this utility model uses multiple protrusions of the contact body as components that directly bear the impact of ore and rock. The layout of the protruding sides of the protrusions facing the inclined chute can disperse the impact energy of the ore and rock, reduce impact noise, and eliminate the need for a high-cost metal lining plate, thus reducing costs. The contact body is set on the inner wall of the ore chutes opposite to the inclined chute of the ore chutes. The connecting component fixes the protrusions to the chutes, and the entire device is attached to the chutes, without occupying additional internal space of the ore chutes and without affecting the efficiency of ore transportation. The other side of each protrusion can make surface contact with the inner wall of the ore chutes, which greatly increases the contact area compared to the point contact of spherical devices, thus dispersing the impact stress. In addition, the connecting component connects multiple protrusions to form a continuous protective surface, preventing local impact damage to the ore chutes. At the same time, the connecting component can be detachably fixed to the inner wall of the ore chutes, and worn protrusions can be removed and replaced individually, making maintenance easy. Ultimately, this effectively reduces the impact wear of ore and rock on the ore chutes and extends the service life of the ore chutes. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The purpose of this utility model is to provide an anti-impact and shock-absorbing wall protection device for ore chute walls, so as to solve the problems existing in the prior art, effectively reduce the impact and wear of ore and rock during ore chute venting on the ore chute walls, and facilitate replacement and maintenance.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1 This embodiment provides a shock-absorbing and vibration-damping wall protection device for wellbore, such as... Figure 1 and Figure 2 As shown, it includes a contact body and a connecting member 3; the contact body is used to be installed on the inner wall of the ore pass 4 opposite to the inclined chute 402 of the ore pass 401; the contact body includes multiple protrusions 1; the protruding side of each protrusion 1 is located on the same side and faces the inclined chute 402; the other side of each protrusion 1 can be in surface contact with the inner wall of the ore pass 4 (seamless fit is achieved through the buffer pad 2, that is, the buffer pad 2 is seamlessly fitted with each protrusion 1 and the inner wall of the ore pass 4); the connecting member 3 is used to connect each protrusion 1, and the connecting member 3 can be detachably fixed on the inner wall of the ore pass 4.

[0020] The multiple protrusions 1 of the contact body serve as components that directly bear the impact of ore and rock. The arrangement of the protruding sides of the protrusions 1 facing the inclined chute 402 can disperse the impact energy of the ore and rock, reduce impact noise, and eliminate the need for a high-cost metal lining plate, thus reducing costs. The contact body is set on the inner wall of the ore pass 4 opposite to the inclined chute 402 of the ore chute 401. The connecting component 3 fixes the protrusions 1 to the ore pass wall. The entire device is attached to the ore pass wall, without occupying additional internal space of the ore pass and without affecting the ore transportation efficiency. The other side of each protrusion 1 can make surface contact with the inner wall of the ore pass 4, which greatly increases the contact area compared to the point contact of the spherical device, thus dispersing the impact stress. In addition, the connecting component 3 connects multiple protrusions 1 to form a continuous protective surface, preventing local impact damage to the ore pass wall. At the same time, the connecting component 3 can be detachably fixed on the inner wall of the ore pass 4, and worn protrusions 1 can be removed and replaced individually, making maintenance easy. Ultimately, this effectively reduces the impact wear of the ore chute 401 on the ore pass wall 4 and extends the service life of the ore pass.

[0021] The following are the relevant settings regarding the contact body and the well wall 4: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, a buffer pad 2 is fixedly installed on the inner wall side of the contact body near the well wall 4. The buffer pad 2 is in surface contact with each protrusion 1 and the inner wall of the well wall 4. Specifically, the installation of the buffer pad 2 further reduces the impact of the discharged ore 401 on the well wall 4, ultimately achieving protection for the well wall 4.

[0022] In the optional embodiments of this example, the preferred choice is that the buffer layer 2 is made of rubber, ultra-high molecular weight polyethylene, ethylene-vinyl acetate, or a foamed composite material, or an anti-impact, anti-wear, or shock-absorbing material.

[0023] Specifically, the thickness of the buffer layer 2 can be adjusted according to the physical properties such as ore flow rate and ore block size, and the buffer layer 2 can be replaced independently.

[0024] The following are the settings instructions for convex body 1: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, the connecting member 3 is internally connected to each protrusion 1, and each pair of adjacent protrusions 1 are in close contact.

[0025] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, convex body 1 is a hemisphere. The shape of the convex side of convex body 1 is not limited to a hemisphere, but can also be other shapes.

[0026] In the optional solutions of this embodiment, it is more preferred that the material of the protrusion 1 is iron, steel, impact-resistant and wear-resistant alloy or non-metallic material.

[0027] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 As shown, the protrusion 1 is provided with a connecting hole 101 for the connecting member 3 to pass through and connect.

[0028] Specifically, the connecting component 3 fixes the hemisphere within the impact range of the ore on the well wall. One side of the hemisphere is completely fitted to the well wall. Multiple hemispheres are internally connected through the connecting component 3. Both the hemisphere and the connecting component 3 can be replaced independently without affecting the structural function.

[0029] The following are the relevant settings for connecting component 3: In the optional embodiments of this example, the connecting member 3 is preferably a chain or rope. It can be replaced by other high-strength chain or rope structures such as steel wire rope.

[0030] Regarding other related settings: Specifically, the connecting component 3, the protrusion 1, and the buffer pad 2 can all be replaced independently without affecting the function of the structure.

[0031] Working Principle: In experimental studies on the impact damage of ore and rock on the shaft wall 4, commonly used protective measures for the shaft wall 4, such as buffer chutes and platforms, reduce the impact force of falling ore to a certain extent, thus reducing the impact damage to the shaft wall. However, these measures also have problems such as large footprint, potentially affecting the layout of underground roadways. The complete spherical rock-breaking device used on-site reduces the direct impact of ore on the shaft wall, but the contact area between the complete spherical rock-breaking device and the shaft wall is small, potentially resulting in multiple single or multiple impacts at the same point, causing damage to the shaft wall 4 over long-term operation. Therefore, a shock-absorbing and vibration-damping wall protection structure (i.e., the structure formed by the protrusion 1 and the buffer pad 2) that can be independently replaced and easily maintained is constructed. The size of the structure can be adjusted according to the shaft conditions, and the increased contact area with the shaft wall, along with the attached buffer pad 2, further reduces the impact on the shaft wall, making it more suitable for protecting the shaft wall 4.

[0032] Considering the impact range of ore and rock on the well wall during the transport of ore and rock in the ore pass, the ore pass anti-impact and shock-absorbing wall protection device of this embodiment is arranged within the impact range to protect the well wall within the impact range.

[0033] After adjusting the structural parameters based on the actual situation and various parameters, the impact position of the ore and rock on the well wall 4 of the ore pass was determined. The device was then installed at the impact position, with the device designed to be at the same height as the impact range of the ore and rock. This ultimately protects the well wall 4 of the ore pass and extends its service life.

[0034] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
