Description

TECHNICAL FIELD

[0001] The utility model relates to coal mine underground equipment protection technical field, specifically to a coal mine underground equipment and its anti -collision protection device. BACKGROUND

[0002] In the coal mine environment, because the space is relatively narrow, the operation equipment is numerous and runs frequently, the risk of collision between the equipment is higher. Especially the distribution box, control box and other electrical equipment in the mine, on the one hand, the equipment is usually composed of relatively fragile shell and internal precise electrical elements, the shell may be deformed and broken in the collision, thereby losing the protection effect on the internal elements; on the other hand, the internal electrical elements such as circuit board, contactor, relay are sensitive to collision, and the collision may cause the elements to loosen, fall off, break, and even damage some precise electronic elements, thereby affecting the normal function of the equipment.

[0003] In the prior art, the patent file with publication number CN214899653U and publication name "anti-collision type distribution box" discloses a distribution box body, the distribution box body is provided with protective components on both sides, the distribution box body is provided with auxiliary protective components on the top, the protective components include anti-collision arc plate, anti-collision outer plate, anti-collision inner plate, elastic filler layer and buffer spring, the buffer spring is fixedly connected to one side of the outer wall of the distribution box body, and the anti-collision inner plate is fixedly connected to one end of the two groups of buffer springs.

[0004] However, for the prior art, on the one hand, when protecting the box type electrical equipment from collision, the existing anti-collision structure takes the box body itself as the supporting frame, which may cause the impact force to be buffered to a certain extent, but still transmitted to the box body, causing vibration of the box body and its internal components. Moreover, in the actual production process, in order to facilitate the handling and installation of the distribution box, control box and other box type electrical equipment, light quality and small thickness metal parts are used for processing and manufacturing, so the overall strength of the box type electrical equipment is low, and the anti-collision structure relying on the box body has weak stability and protection ability.

[0005] On the other hand, when protecting the box type electrical equipment in the coal mine, because the space in the coal mine is relatively narrow, the box type electrical equipment is generally installed close to the wall during installation, and the front of the box type electrical equipment faces outward, so that the front of the equipment is more likely to be collided during use. The existing anti-collision structure cannot effectively protect the front of the box type electrical equipment, so that the equipment is easily damaged during use. UTILITY MODEL CONTENTS

[0072] The specific embodiments of the utility model embodiments will be described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model embodiments, and are not used to limit the utility model embodiments.

[0073] Figure 1 is the structure diagram of the anti-collision protection device of the coal mine underground equipment according to an embodiment of the utility model. In Figure 1 , the anti-collision protection device can include a support base 1, a top protection mechanism 3, a side protection mechanism 4 and a front protection mechanism 5.

[0074] The equipment body 2 is arranged on the top of the support base 1, the top protection mechanism 3 is arranged above the equipment body 2 and is connected with the top of the support base 1, for protecting the top of the equipment body 2. The side protection mechanism 4 is arranged on the side of the equipment body 2 and is connected with the top protection mechanism 3, for protecting the side of the equipment body 2. The front protection mechanism 5 is arranged on the top of the support base 1 and is located in front of the equipment body 2, for protecting the front of the equipment body 2.

[0075] After the equipment body 2 is installed inside the anti-collision protection device, the back of the anti-collision protection device can be installed with the well wall, and then the anti-collision protection device can be subjected to the top, side and front collision forces. When subjected to the top collision force, the top protection mechanism 3 can shield and protect it, and the collision force is transmitted to the support base 1 through the connection mode with the support base 1; the collision force does not act on the equipment body 2, thereby achieving the purpose of protecting the equipment body 2. When subjected to the side collision force, the side protection mechanism 4 can shield and protect it, and the collision force is transmitted through the top protection mechanism 3 and the support base 1; the collision force does not act on the equipment body 2, thereby achieving the purpose of protecting the equipment body 2. When subjected to the front collision force, the front protection mechanism 5 can shield and protect it, and the collision force is transmitted to the support base 1 through the connection mode with the support base 1; the collision force does not act on the equipment body 2, thereby achieving the purpose of protecting the equipment body 2.

[0076] The traditional anti-collision structure mainly takes the box body as a support frame, and when subjected to a collision, the acting force of the anti-collision structure directly acts on the box body, thereby causing damage to the box body. Meanwhile, for the anti-collision structure installed against the well wall, the probability of being subjected to a front collision is greater, thereby causing a high risk of damage to the box body. In the embodiment of the utility model, the top protection mechanism 3 is connected with the support base 1, the side protection mechanism 4 is connected with the top protection mechanism 3, and the front protection mechanism 5 is connected with the support base 1, which can realize non-contact protection of the equipment body 2, that is, when the top protection mechanism 3, the side protection mechanism 4 or the front protection mechanism 5 is protected, the collision force can be prevented from acting on the equipment body 2, thereby effectively improving the protection effect of the equipment body 2 and ensuring the reliability and stability of the operation of the equipment body 2.

[0077] In the embodiment of the utility model, as shown in Figure 2 and Figure 4 The top protection mechanism 3 can include a top protection plate 33, a plurality of first connecting outer pipes 31, a plurality of first connecting inner pipes 32 and a plurality of first damping assemblies. Specifically, the first connecting outer pipe 31 can include a first groove.

[0078] The bottom end of the first connecting outer pipe 31 is connected with the top of the support base 1, and the top of the first connecting outer pipe 31 is provided with a first groove. The first connecting inner pipe 32 is arranged inside the corresponding first groove and is in sliding connection with the inner wall of the corresponding first groove, and the top end of the first connecting inner pipe 32 extends out of the corresponding first groove and is connected with the bottom of the top protection plate 33. A plurality of first damping assemblies are arranged inside the corresponding first groove for buffering the sliding of the first connecting inner pipe 32.

[0079] When the device body 2 is subjected to a top collision force, the top protection plate 33 is directly contacted with the collision force and shields the colliding object. The first connecting inner tube 32 slides along the first connecting outer tube 31, and the first damping assembly is compressed and deformed to buffer the first connecting inner tube 32; at the same time, the first connecting outer tube 31 transmits the collision force to the supporting base 1, thereby effectively resisting the top collision force to realize the top protection of the device body 2.

[0080] In the embodiment of the utility model, as shown in Figure 2 and Figure 4 The top protection plate 33 can include a first buffer rubber pad 34. Specifically, the first buffer rubber pad 34 is arranged at the top of the top protection plate 33 and can preliminarily buffer the collision force, further improving the protection effect of the top collision force.

[0081] In the embodiment of the utility model, as shown in Figure 4 The first damping assembly can include a first damping rod 35 and a first spring 36. Specifically, the first damping rod 35 can include a damper.

[0082] One end of the first damping rod 35 is connected to the bottom end of the first connecting inner tube 32, and the other end of the first damping rod 35 is connected to the inner bottom of the first recess. The first spring 36 is sleeved on the outer side of the first damping rod 35, one end of the first spring 36 is connected to the bottom end of the first connecting inner tube 32, and the other end of the first spring 36 is connected to the inner bottom of the first recess.

[0083] When the top protection plate 33 is subjected to a collision force, the first connecting inner tube 32 simultaneously extrudes the first damping rod 35 and the first spring 36 to realize the buffering of the top protection plate 33. The buffering mode of the first damping rod 35 and the first spring 36 can further improve the buffering effect of the top collision force, i.e., further improve the safety and reliability of the device body 2.

[0084] In the embodiment of the utility model, the number of the first connecting outer tube 31, the first connecting inner tube 32 and the first damping assembly can be set according to the shape of the device body 2, with high stability as the principle. Specifically, since the common device body 2 is in the shape of a rectangular parallelepiped, the number of the first connecting outer tube 31, the first connecting inner tube 32 and the first damping assembly can include four groups and be distributed in a square shape, with higher stability.

[0085] In the embodiment of the utility model, as shown in Figure 2 and Figure 4As shown, the side protection mechanism 4 can include a side protection plate 43, a plurality of second connecting outer pipes 41, a plurality of second connecting inner pipes 42, and a plurality of second damping assemblies. Specifically, the second connecting outer pipe 41 can include a second groove.

[0086] One end of the second connecting outer pipe 41 is connected to the side of the first connecting outer pipe 31, and the other end of the second connecting outer pipe 41 is provided with a second groove. The second connecting inner pipe 42 is arranged in the corresponding second groove and is in sliding connection with the inner wall of the corresponding second groove. One end of the second connecting inner pipe 42 extends out of the second groove and is connected to the side protection plate 43. A plurality of second damping assemblies are arranged in the corresponding second groove for buffering the sliding of the second connecting inner pipe 42.

[0087] When the device body 2 is subjected to a side collision force, the side protection plate 43 directly contacts the collision force and blocks the collision object. The second connecting inner pipe 42 slides along the second connecting outer pipe 41, and the second damping assembly is compressed and deformed to buffer the second connecting inner pipe 42; at the same time, the second connecting outer pipe 41 transmits the collision force to the first connecting outer pipe 31, and transmits it to the top protection plate 33 and the support base 1 through the first connecting outer pipe 31, thereby effectively resisting the side collision force to realize the side protection of the device body 2.

[0088] In the embodiment of the utility model, considering that the device body 2 is generally installed on the back and the well wall, the number of the side protection mechanism 4 can include two groups, and is symmetrically arranged on the opposite sides of the device body 2.

[0089] In the embodiment of the utility model, as shown in Figure 2 and Figure 4 As shown, the side protection plate 43 can include a second buffer rubber pad 44. Specifically, the second buffer rubber pad 44 is arranged on the side of the side protection plate 43 away from the second connecting inner pipe 42, which can preliminarily buffer the collision force, further improving the protection effect of the side collision force.

[0090] In the embodiment of the utility model, as shown in Figure 4 As shown, the second damping assembly can include a second damping rod 45 and a second spring 46. Specifically, the second damping rod 45 can include a damper.

[0091] One end of the second damping rod 45 is connected to the other end of the second connecting inner pipe 42, and the other end of the second damping rod 45 is connected to the inner bottom of the second groove. The second spring 46 is sleeved on the outer side of the second damping rod 45, one end of the second spring 46 is connected to the other end of the second connecting inner pipe 42, and the other end of the second spring 46 is connected to the inner bottom of the second groove.

[0092] When the side protection plate 43 is subjected to the impact force, the second connecting inner tube 42 simultaneously extrudes the second damping rod 45 and the second spring 46, so as to realize the buffering of the side protection plate 43. The buffering mode of the second damping rod 45 and the second spring 46 can further improve the buffering effect of the top impact force, that is, further improve the safety and reliability of the equipment main body 2.

[0093] In the embodiment of the utility model, the number of the second connecting outer tube 41, the second connecting inner tube 42 and the second damping assembly can be set according to the shape of the equipment main body 2, and the stability is high. Specifically, the number of the second connecting outer tube 41, the second connecting inner tube 42 and the second damping assembly on each first connecting outer tube 31 can include two groups, and is distributed in an upper and lower manner.

[0094] In the embodiment of the utility model, as shown in Figure 2 , Figure 3 and Figure 5 , the front protection mechanism 5 can include a sliding rail 51, a plurality of sliding blocks 52, a plurality of supporting frames 53, a plurality of front protection plates 54 and an electric push rod 56. Specifically, the number of the sliding block 52, the supporting frame 53, the front protection plate 54 and the electric push rod 56 can include two groups, and the two groups of electric push rods 56 are symmetrically distributed and connected with the mutually far ends of the two groups of sliding blocks 52.

[0095] The sliding rail 51 is arranged at the top of the supporting base 1, and the plurality of sliding blocks 52 are slidingly arranged in the interior of the sliding rail 51. The plurality of supporting frames 53 are fixedly arranged at the top of the plurality of sliding blocks 52, and the plurality of front protection plates 54 are arranged on the corresponding supporting frames 53. The electric push rod 56 is arranged in the interior of the sliding rail 51, and the output end of the electric push rod 56 is connected with the sliding block 52.

[0096] When the front side / front portion / front surface of the equipment main body 2 needs to be protected, the two groups of electric push rods 56 are started to drive the two groups of sliding blocks 52 to relatively slide along the sliding rail 51 to make the two groups of front protection plates 54 close to each other and be attached, so as to realize the protection and blocking of the front surface of the equipment main body 2. Conversely, when the equipment main body 2 needs to be maintained and debugged, the two groups of electric push rods 56 can be started to drive the two groups of sliding blocks 52 to move away from each other, so that the two groups of front protection plates 54 can be separated.

[0097] In the embodiment of the utility model, as shown in Figure 5 and Figure 6 , the front protection mechanism 5 can further include a first mounting frame 55, two groups of first connecting rods 511, two groups of second connecting rods 512, two groups of second mounting frames 513, two groups of first fixing frames 57, two groups of second fixing frames 510, two groups of third damping rods 58, two groups of third springs 59 and two groups of buffer rubber wheels 514.

[0098] The first mounting frame 55 is arranged on the side of the front protective plate 54 away from the corresponding support frame 53.

Two groups of first fixed frames 57 are symmetrically arranged on the first mounting frame 55, and one end of the first fixed frame 57 is movably connected with the first mounting frame 55. Two groups of second fixed frames 510 are arranged at the other end of the two groups of second connecting rods 512, and one end of the second fixed frame 510 is movably connected with the other end of the second connecting rod 512. One end of the two groups of third damping rods 58 is fixedly connected with the other end of the corresponding second fixed frame 510, and the other end of the two groups of third damping rods 58 is fixedly connected with the corresponding first fixed frame 57.

[0099] When the object colliding with the front of the device body 2 is large, the buffer rubber wheel 514 will contact the object colliding with it, and the buffer rubber wheel 514 will move the second mounting frame 513, and the power will be transmitted along the second connecting rod 512 and the first connecting rod 511, and the third damping rod 58 and the third spring 59 will be deformed to buffer the kinetic energy of the impact, thereby improving the stability of the front protection mechanism 5 when protecting the front of the device body 2. At the same time, the kinetic energy of the impact is finally transmitted to the support base 1 through the front protection mechanism 5, and will not act on the surface of the device body 2, so as to protect the device body 2.

[0100] On the other hand, the utility model also provides a coal mine underground equipment. Specifically, the coal mine underground equipment can include a device body 2 and a collision protection device according to any one of the above, and the device body 2 is arranged in the interior of the collision protection device.

[0102] Further, the object moving over is blocked by the frontal protection plate 54, thereby protecting the device main body 2, if the collided object is large, the buffer rubber wheel 514 will be in contact with the collided object, the impact is buffered by the buffer rubber wheel 514, at the same time, the second mounting frame 513 is moved by the buffer rubber wheel 514, at this time, the power is transmitted along the second connecting rod 512 and the first connecting rod 511, at the same time, the third damping rod 58 and the third spring 59 are deformed to buffer the kinetic energy of the impact, thereby improving the stability of the frontal protection mechanism 5 when protecting the front of the device main body 2.
