Technical Field
[0001] This utility model relates to the field of electromechanical protection devices, specifically a mining electromechanical protection device. Background Technology
[0002] Ore mining requires the deployment of various electromechanical equipment on-site, such as generator sets and water pumps. To prevent equipment damage caused by falling rocks, a set of protective devices is usually installed on the outside of the electromechanical equipment to improve its safety.
[0003] Most of the electromechanical protection devices in current ore mining areas are similar in overall structure, with a steel arched frame as the main body and an outer sheet metal covering. In actual use, they have some functional deficiencies and room for improvement. For example, when encountering a large rock impact, the frame deforms and presses down, which will directly compress the electromechanical equipment below, causing the equipment surface to be dented or the pipeline to be damaged. They do not have the function of flexible padding for buffering.
[0004] Now, a new type of electromechanical protection device for mining operations is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a mining electromechanical protection device to solve the problem mentioned in the background art of not having the function of flexible pad buffer.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mining electromechanical protection device, comprising an arched inner steel frame, with bottom support frames fixedly connected to both sides of the bottom of the arched inner steel frame, multiple sets of outer guard bars provided on the outside of the arched inner steel frame, multiple inner support ribs fixedly connected inside the outer guard bars, two sets of aluminum alloy collapse boxes fixedly connected between the arched inner steel frame and the outer guard bars, two sets of guiding grooves provided at the front and rear ends of the aluminum alloy collapse boxes, the outer guard bars covered with wire mesh, steel counterweights tied to both sides of the bottom of the wire mesh, and an inflatable component provided at the top of the bottom support frame to protect the equipment from crush damage.
[0007] The inflatable assembly includes an outer protective frame, which is fixedly connected to the top of the bottom support frame. An air bag is fixedly connected inside the outer protective frame, and a solenoid valve is installed at the front end of the air bag. An air bladder is installed at the top of the inner arched steel frame. An air tube is movably connected between the solenoid valve and the air bladder. A PLC controller is installed at the top of the outer protective frame, and a vibration sensor is fixedly connected at the middle position of the top of the outer protective frame.
[0008] As a further technical solution of this utility model, the front and rear ends of the outer protective frame and the air bag are flush, and the outer protective frame is symmetrically distributed about the vertical center line of the arched inner steel frame.
[0009] As a further technical solution of this utility model, the air bag, air tube and air bladder are internally connected, and the front and rear ends of the arched inner steel frame and air bladder are flush.
[0010] As a further technical solution of this utility model, the airbag is elastic, and the solenoid valve, vibration sensor, and PLC controller are electrically connected.
[0011] As a further technical solution of this utility model, the outer guard bars are arranged at equal intervals, and the end faces of the outer guard bars and the inner support ridges are flush.
[0012] As a further technical solution of this utility model, the front and rear ends of the arched inner steel frame and the wire mesh are flush, and the bottom ends of the bottom support frame and the steel counterweight are flush.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the electromechanical protection device for mining not only realizes the function of flexible pad buffer, but also realizes the function of collapse energy absorption and impact reduction, and also realizes the function of flexible protection to mitigate puncture.
[0014] (1) By setting up an outer protective frame, air bag, solenoid valve, air pipe, air bag, vibration sensor and PLC controller, when in use, the arched inner steel frame serves as an internal support frame, which, together with the outer guard bar, can withstand the impact of falling rocks. When there is an impact from falling rocks, the impact of the outer protective frame is detected by the vibration sensor. The PLC controller opens the solenoid valve according to the vibration signal transmitted by the vibration sensor. The compressed air in the air bag is quickly blown into the air bag along the air pipe. The air bag inflates quickly. Even if the arched inner steel frame collapses and deforms, the air bag acts as a diaphragm, which can prevent the equipment below from being damaged, thus realizing the function of flexible diaphragm buffer.
[0015] (2) By setting up an outer guard bar, an inner support rib, an aluminum alloy crumple box and an induction groove, when the falling rock impacts the protective device, multiple sets of outer guard bars can directly resist the impact of the falling rock. The aluminum alloy crumple box will quickly crumple and deform under impact to reduce the impact. The induction groove can guide the aluminum alloy crumple box to crumple and deform. The inner support rib can increase the structural strength of the outer guard bar while ensuring its lightweight nature, thus realizing the function of crumple energy absorption and impact reduction.
[0016] (3) By setting up wire mesh and steel counterweight, when in use, the outer guard bar serves as a support, and together with the external wire mesh, it forms a flexible protection. The fine wire mesh can block the puncture of small stones, and the steel counterweight can fix the position of the wire mesh, thus realizing the function of flexible protection to alleviate puncture.

[0023] 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.
[0024] Example: Please refer to Figure 1-4 A mining electromechanical protection device includes an arched inner steel frame 1, with a bottom support frame 2 fixedly connected to both sides of the bottom of the arched inner steel frame 1, and an inflation component that can protect the equipment from crush damage at the top of the bottom support frame 2.
[0025] Please see Figure 1-4 A mining electromechanical protection device also includes an inflation component, which includes an outer protective frame 3, which is fixedly connected to the top of the bottom support frame 2. An air bag 4 is fixedly connected inside the outer protective frame 3. A solenoid valve 5 is installed at the front end of the air bag 4. An air bladder 7 is installed at the top of the inside of the arched inner steel frame 1. An air pipe 6 is movably connected between the solenoid valve 5 and the air bladder 7. A PLC controller 9 is installed at the top of the outer protective frame 3. A vibration sensor 8 is fixedly connected at the middle position of the top of the outer protective frame 3.
[0026] The front and rear ends of the outer protective frame 3 and the air bag 4 are flush. The outer protective frame 3 is symmetrically distributed about the vertical center line of the arched inner steel frame 1. The air bag 4, the air pipe 6, and the air bladder 7 are internally connected. The front and rear ends of the arched inner steel frame 1 and the air bladder 7 are flush. The air bladder 7 is elastic. The solenoid valve 5, the vibration sensor 8, and the PLC controller 9 are electrically connected. The flexible septum forms a support, while protecting the electromechanical equipment below.
[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the impact of the outer protective frame 3 is detected by the vibration sensor 8. The PLC controller 9 opens the solenoid valve 5 based on the vibration signal transmitted by the vibration sensor 8. Compressed air in the air bag 4 is quickly blown into the air bladder 7 along the air pipe 6. The air bladder 7 inflates rapidly. Even if the arched inner steel frame 1 collapses and deforms, the air bladder 7 acts as a cushion to prevent damage to the equipment below. The specific model of the PLC controller 9 is S7-200, the specific model of the vibration sensor 8 is ZHLV-8, and the specific model of the solenoid valve is 2v025-08. The solenoid valve 5, the vibration sensor 8, and the PLC controller 9 are electrically connected. This technology is existing technology and will not be described in detail.
[0028] The arched inner steel frame 1 is provided with multiple sets of outer guard bars 10. Multiple inner support ribs 11 are fixedly connected inside the outer guard bars 10. Two sets of aluminum alloy crumple boxes 12 are fixedly connected between the arched inner steel frame 1 and the outer guard bars 10. Two sets of guide grooves 13 are provided at the front and rear ends of the aluminum alloy crumple boxes 12 respectively. The outer guard bars 10 are arranged at equal intervals. The end faces of the outer guard bars 10 and the inner support ribs 11 are flush. The impact is reduced by crumple energy absorption.
[0029] Specifically, such as Figure 1 and Figure 4 As shown, multiple sets of outer guard bars 10 can directly withstand the impact of falling rocks. The aluminum alloy crumple box 12 collapses and deforms rapidly upon impact, reducing the impact. The induction groove 13 can guide the aluminum alloy crumple box 12 to collapse and deform. The inner support rib 11 can increase the structural strength of the outer guard bar 10 while ensuring its lightweight nature.
[0030] The outer guard bar 10 is covered with a wire mesh 14. Steel counterweights 15 are tied to both sides of the bottom of the wire mesh 14. The front and rear ends of the arched inner steel frame 1 and the wire mesh 14 are flush. The bottom support frame 2 and the bottom end of the steel counterweights 15 are flush. The flexible protection resists the penetration of stones.
[0031] Specifically, such as Figure 1 and Figure 5 As shown, the outer guard bar 10 serves as a support, and together with the external wire mesh 14, they form a flexible protection. The fine wire mesh 14 can block the penetration of small stones, and the steel counterweight 15 can fix the position of the wire mesh 14.
[0032] The computer software involved in the PLC controller and other hardware carriers in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.
[0033] Therefore, the "PLC controller", "solenoid valve", "vibration sensor" and other components involved in this application are all physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the electromechanical protection device of this application, in order to solve the corresponding technical problems to be solved by this application.
[0034] Working Principle: In use, the arched inner steel frame 1 serves as an internal support frame, working in conjunction with the outer guardrail 10 to withstand the impact of falling rocks. When a rock falls, the impact of the outer guardrail 3 is detected by the vibration sensor 8. The PLC controller 9 activates the solenoid valve 5 based on the vibration signal transmitted by the vibration sensor 8. Compressed air in the air tank 4 is rapidly inflated into the airbag 7 along the air pipe 6. The airbag 7 inflates rapidly, and even if the arched inner steel frame 1 collapses and deforms, the airbag 7 acts as a buffer, preventing damage to the equipment below. When a rock falls and impacts the protective device, multiple sets of outer guardrails 10 can directly withstand the impact. The aluminum alloy collapse box 12 quickly collapses and deforms upon impact, reducing the impact. The induction groove 13 guides the aluminum alloy collapse box 12 to collapse and deform. The inner support rib 11 increases the structural strength of the outer guardrail 10 while ensuring its lightweight nature. The outer guard bar 10 serves as a support, and together with the external wire mesh 14, it forms a flexible protection. The fine wire mesh 14 can block the penetration of small stones, and the steel counterweight 15 can fix the position of the wire mesh 14.
[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
