Description

Technical Field

[0001] The utility model belongs to the technical field of mine emergency stop switches, and particularly relates to a mine emergency stop switch. Background Technique

[0002] The mine emergency stop switch is a safety device mainly used to quickly stop the operation of equipment in case of emergency to ensure the safety of personnel. The working principle of the mine emergency stop switch is to achieve the emergency stop of the equipment through the action of the emergency stop pull ring or the travel switch. For example, when a certain force is applied to the emergency stop pull ring on either side of the emergency stop switch and displacement occurs, the travel switch inside the emergency stop switch acts, the contact state flips and self-locks, thereby achieving the emergency stop of the equipment.

[0003] There are various types of mine emergency stop switches, including explosion-proof emergency stop switches and intrinsically safe emergency stop switches, etc. Among them, the intrinsically safe emergency stop switch has the advantages of small size, light weight and convenient installation, and is widely used in parts such as belt conveyors that require emergency stop. However, the existing mine intrinsically safe emergency stop switch lacks an anti-vibration installation mechanism, resulting in being easily affected by external vibration during use, and thus easily increasing the probability of malfunction or damage of the mine intrinsically safe emergency stop switch, there are certain potential safety hazards.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a mine emergency stop switch.

[0005] The information disclosed in this background technical part is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a mine emergency stop switch, which can solve the problem that the mine intrinsically safe emergency stop switch is easily affected by vibration.

[0007] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0008] A mine emergency stop switch includes: an emergency stop switch main body and an anti-vibration installation mechanism;

[0009] The anti-vibration installation mechanism is connected to the emergency stop switch main body. The anti-vibration installation mechanism includes a connecting plate, the connecting plate is connected to the emergency stop switch main body through a pair of bolts, one side of the connecting plate is provided with a mounting plate, at least a pair of mounting holes are provided on the mounting plate, a first fixing rod and a second fixing rod are connected to the mounting plate, one ends of the first fixing rod and the second fixing rod both pass through the connecting plate, and elastic sleeves are arranged on the outer sides of the first fixing rod and the second fixing rod, and the elastic sleeves are arranged between the connecting plate and the mounting plate.

[0010] In one or more embodiments of the present utility model, the vertical cross-sectional area of the mounting plate is larger than that of the connecting plate, which facilitates the installation of the first fixing rod and the second fixing rod.

[0011] In one or more embodiments of the present utility model, the number of the mounting holes is two, and the two mounting holes are symmetrical with respect to the elastic sleeve, which facilitates the overall installation of the emergency stop switch body and the anti-vibration mounting mechanism so that the emergency stop switch body can be used.

[0012] In one or more embodiments of the present utility model, a buffer tube is fixedly connected to the connecting plate, a compression cavity is provided in the buffer tube, and one end of the first fixing rod is arranged in the compression cavity.

[0013] In one or more embodiments of the present utility model, a piston is connected to one end of the first fixing rod located in the compression cavity. The piston is made of rubber material. When the connecting plate slides relative to the mounting plate, the piston can move in the compression cavity. When the connecting plate approaches the mounting plate, the piston will compress the gas in the compression cavity. The compressed gas in the compression cavity can play a buffering role, so that the connecting plate is not easy to contact the mounting plate, and is used to reduce the influence of external vibration on the emergency stop switch body.

[0014] In one or more embodiments of the present utility model, an airbag is embedded on the side of the buffer tube away from the first fixing rod. A connecting hole is provided in the buffer tube, and the compression cavity is communicated with the inside of the airbag through the connecting hole. When the gas in the compression cavity is compressed, the gas in the compression cavity will enter the airbag through the connecting hole, causing the airbag to expand. The expanded airbag can also play a buffering role, and is used to reduce the influence of external vibration on the emergency stop switch body.

[0015] In one or more embodiments of the present utility model, the expansion distance of the airbag is greater than the distance between the buffer tube and the emergency stop switch body. If the airbag continues to expand, the expanded airbag will contact the emergency stop switch body, and the emergency stop switch body can generate a reaction force on the airbag to play a further buffering role.

[0016] In one or more embodiments of the present utility model, a groove is formed in the second fixing rod.

[0017] In one or more embodiments of the present utility model, a buffer belt is connected to the connecting plate. The buffer belt is connected to the connecting plate by screws. The buffer belt corresponds to the groove. The buffer belt is used to increase the resistance of the relative sliding between the connecting plate and the mounting plate, so that the connecting plate is not easy to contact the mounting plate.

[0018] In one or more embodiments of the present utility model, the buffer belt is made of an elastic material, and the maximum moving distance of the connecting plate is less than the distance between the buffer belt and the emergency stop switch body, so that the second fixing rod is not easily in contact with the emergency stop switch body, thereby ensuring the safety of use of the emergency stop switch body.

[0019] Compared with the prior art, a mine emergency stop switch of the present utility model can increase the anti-vibration ability of the intrinsically safe mine emergency stop switch, making the intrinsically safe mine emergency stop switch not easily affected by external vibrations, thereby reducing the probability of the intrinsically safe mine emergency stop switch malfunctioning or being damaged due to vibrations and ensuring the safe operation of the intrinsically safe mine emergency stop switch.

Detailed implementation manners

[0030] In order to enable those skilled in the art to better understand the technical solutions in this utility model, the following will clearly and completely describe the technical solutions in the embodiments of this utility model with reference to the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this utility model.

[0031] As Figures 1 to 7 shown, a mine emergency stop switch in an embodiment of this utility model includes an emergency stop switch body 1 and an anti-vibration mounting mechanism 2.

[0032] Among them, the emergency stop switch body 1 is a commercially available product and can be directly purchased and used.

[0033] As Figures 1 to 7 shown, the anti-vibration mounting mechanism 2 is connected to the emergency stop switch body 1. Through the anti-vibration mounting mechanism 2, the installation of the emergency stop switch body 1 can be realized so that the emergency stop switch body 1 can be used. At the same time, the anti-vibration mounting mechanism 2 can also buffer and protect the emergency stop switch body 1, so that when the emergency stop switch body 1 is in use, it is not easily affected by external vibrations, and thus the probability of the emergency stop switch body 1 malfunctioning or being damaged due to vibrations can be reduced, ensuring the safe operation of the emergency stop switch body 1.

[0034] Among them, the anti-vibration mounting mechanism 2 includes a connecting plate 201. The connecting plate 201 is connected to the emergency stop switch body 1 by a pair of bolts. One side of the connecting plate 201 is provided with a mounting plate 202, and the mounting plate 202 is used to fix the emergency stop switch body 1 so that the emergency stop switch body 1 can be used.

[0035] Preferably, the vertical cross-sectional area of the mounting plate 202 is larger than the vertical cross-sectional area of the connecting plate 201, which is convenient for installing the first fixing rod 204 and the second fixing rod 205.

[0036] In addition, at least a pair of mounting holes 203 are provided on the mounting plate 202. Pass the bolts through the mounting holes 203 and then connect the bolts to the wall surface or other equipment to fix the emergency stop switch body 1.

[0037] Preferably, the number of the mounting holes 203 is two, and the two mounting holes 203 are symmetrical with respect to the elastic sleeve 206, which facilitates the overall installation of the emergency stop switch body 1 and the anti-vibration mounting mechanism 2 so that the emergency stop switch body 1 can be used.

[0038] Specifically, a first fixing rod 204 and a second fixing rod 205 are connected to the mounting plate 202. One ends of the first fixing rod 204 and the second fixing rod 205 both pass through the connecting plate 201. The first fixing rod 204 and the second fixing rod 205 are used to enhance the connection effect between the connecting plate 201 and the mounting plate 202, so that the emergency stop switch body 1 can be firmly held during installation and use.

[0039] Preferably, the length of the first fixing rod 204 is greater than that of the second fixing rod 205. The first fixing rod 204 is used to connect the piston 209, and the piston 209 is used to limit the moving distance of the first fixing rod 204 and the second fixing rod 205, so that the first fixing rod 204 and the second fixing rod 205 are not likely to completely slide out of the connecting plate 201.

[0040] In addition, elastic sleeves 206 are provided on the outer sides of the first fixing rod 204 and the second fixing rod 205, and the elastic sleeves 206 are arranged between the connecting plate 201 and the mounting plate 202. When the mounting plate 202 vibrates, the first fixing rod 204 and the second fixing rod 205 connected to the mounting plate 202 will slide relative to the connecting plate 201. The elastic sleeves 206 can increase the resistance of the relative sliding between the connecting plate 201 and the mounting plate 202, making it difficult for the connecting plate 201 to contact the mounting plate 202, and thus reducing the influence of vibration on the emergency stop switch body 1.

[0041] As Figures 1 to 7 shown, a buffer tube 207 is fixedly connected to the connecting plate 201. A compression chamber 208 is provided in the buffer tube 207, and one end of the first fixing rod 204 is arranged in the compression chamber 208. A piston 209 is connected to the end of the first fixing rod 204 located in the compression chamber 208, and the piston 209 is made of rubber. When the connecting plate 201 slides relative to the mounting plate 202, the piston 209 can move in the compression chamber 208. When the connecting plate 201 approaches the mounting plate 202, the piston 209 will compress the gas in the compression chamber 208, and the compressed gas in the compression chamber 208 is used to increase the moving resistance of the connecting plate 201, making it difficult for the connecting plate 201 to contact the mounting plate 202, that is, the emergency stop switch body 1 connected to the connecting plate 201 will not be affected by vibration.

[0042] At the same time, the piston 209 can also play a limiting role, making it difficult for the first fixing rod 204 and the second fixing rod 205 to completely disengage from the connecting plate 201, ensuring the integrity of the anti-vibration mounting mechanism 2.

[0043] Among them, an airbag 210 is embedded on a side of the buffer tube 207 away from the first fixing rod 204. A connection hole 211 is provided in the buffer tube 207. The compression chamber 208 is communicated with the inside of the airbag 210 through the connection hole 211. When the gas in the compression chamber 208 is compressed, the gas in the compression chamber 208 will enter the airbag 210 through the connection hole 211, causing the airbag 210 to expand. The expanded airbag 210 can also play a buffering role to reduce the impact of external vibration on the emergency stop switch body 1.

[0044] Preferably, the expansion distance of the airbag 210 is greater than the distance between the buffer tube 207 and the emergency stop switch body 1. If the airbag 210 continues to expand, the expanded airbag 210 will contact the emergency stop switch body 1, and the emergency stop switch body 1 can generate a reaction force on the airbag 210 to play a further buffering role.

[0045] As Figures 1 to 7 shown, a groove 212 is drilled in the second fixing rod 205, and a buffer belt 213 is connected to the connecting plate 201. The buffer belt 213 is connected to the connecting plate 201 by screws, and the buffer belt 213 corresponds to the groove 212. The buffer belt 213 is used to further increase the resistance to the relative sliding of the connecting plate 201 and the mounting plate 202, so that the connecting plate 201 is not easily in contact with the mounting plate 202, thereby reducing the impact of the vibration of the mounting plate 202 on the emergency stop switch body 1.

[0046] Preferably, the buffer belt 213 is made of an elastic material, and the maximum moving distance of the connecting plate 201 is less than the distance between the buffer belt 213 and the emergency stop switch body 1, so that the second fixing rod 205 is not easily in contact with the emergency stop switch body 1, thereby ensuring the use safety of the emergency stop switch body 1.

[0047] During specific use, a pair of bolts are passed through the mounting holes 203, and then the bolts are connected to a wall surface or other equipment to fix the mounting plate 202, the first fixing rod 204 and the second fixing rod 205. The connecting plate 201 is connected to the mounting plate 202 through the first fixing rod 204 and the second fixing rod 205, and the emergency stop switch body 1 is mounted on the connecting plate 201. Therefore, the emergency stop switch body 1 will also be fixed.

[0048] If the mounting plate 202 vibrates, the first fixing rod 204 and the second fixing rod 205 connected to the mounting plate 202 will slide relative to the connecting plate 201. The elastic sleeve 206 provided between the connecting plate 201 and the mounting plate 202 will increase the resistance to the relative sliding of the connecting plate 201 and the mounting plate 202 to reduce the probability of contact between the connecting plate 201 and the mounting plate 202.

[0049] Meanwhile, when the connecting plate 201 slides relative to the mounting plate 202, the piston 209 will compress the gas in the compression chamber 208. The compressed gas in the compression chamber 208 will enter the airbag 210 through the connecting hole 211, causing the airbag 210 to expand. The expanded airbag 210 can also play a buffering role to further reduce the probability of contact between the connecting plate 201 and the mounting plate 202. In addition, when the connecting plate 201 moves closer to the mounting plate 202, the buffer belt 213 elongates and deforms under the action of the second fixing rod 205, and the elastic potential energy of the buffer belt 213 increases. The buffer belt 213 can also buffer the relative sliding of the connecting plate 201 and the mounting plate 202, making it difficult for the connecting plate 201 to contact the mounting plate 202.

[0050] Through the mutual cooperation of the connecting plate 201, the mounting plate 202, the first fixing rod 204 and the second fixing rod 205 in this application, the vibration of the mounting plate 202 can be converted into the relative sliding of the connecting plate 201 and the mounting plate 202. Then, through the mutual cooperation of the elastic sleeve 206, the airbag 210 and the buffer belt 213, the resistance of the relative sliding of the connecting plate 201 and the mounting plate 202 can be increased, making it difficult for the connecting plate 201 to contact the mounting plate 202. Furthermore, the influence of the vibration of the mounting plate 202 on the emergency stop switch main body 1 can be reduced, and the probability of the emergency stop switch main body 1 malfunctioning or being damaged due to vibration can be reduced, so as to ensure the safe operation of the emergency stop switch main body 1.
