Description

Technical Field

[0001] This utility model relates to the field of mine car ground guide technology, specifically a coal mine electromechanical transportation ground guide device. Background Technology

[0002] The transportation tools commonly used in coal mines, such as cranes and mine cars, are addressed in this solution for mine car safety. The applicable working conditions cause them to be in an uphill or downhill working state. When it is necessary to stop them in a reasonable and safe position, ground stops are required to block the movement of the transportation device.

[0003] For example, the "Coal Mine Transportation Ground Stop Device" disclosed in the Chinese patent (patent number: CN211844439U) can solve the problem of vehicles falling into the mine under their own weight by the cooperation of the ground stop plate, the first spring, the second spring and the second rack.

[0004] However, this patent still has some shortcomings. Because the impact force exerted by the mine car on the baffle has many uncontrollable factors, using only springs for buffering can easily cause some problems due to the single elastic coefficient of the spring. When the spring strength is high, the mine car is prone to a relatively strong reaction force when the baffle comes into contact with it. When the spring strength is low, the buffering effect is poor, and the mine car is prone to sideslip when it hits the baffle, which can also cause safety accidents. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a ground stop device for coal mine electromechanical transportation, which solves the problem that relying solely on springs to offset buffering force is ineffective.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coal mine electromechanical transport ground stop device, including a mounting base plate, on which a buffer adjustment component and a pusher component connected to the buffer adjustment component are provided, the buffer adjustment component being composed of a buffer component and a pusher component;

[0007] The buffer is rotatably mounted on the bottom of the pusher;

[0008] The buffer includes a left and right symmetrical base sleeve, a push plate is slidably installed inside each of the two base sleeves, a touch plate is rotatably provided on the two push plates, and an elastic element is installed between the touch plate and the rear push member.

[0009] The pushing member includes a pushing plate that is connected to the contact plate. The pushing plate is rotatably connected to the contact plate. A connecting plate that is connected to the rear pushing plate is provided on the pushing plate. A pushing member is installed between the pushing plate and the positioning plate.

[0010] In one embodiment, the pusher includes a positioning seat disposed on a mounting base, a positioning plate being mounted obliquely on the positioning seat, and an elastic member disposed between the contact plate and the positioning plate and rotating on the positioning plate.

[0011] The touch plate and the positioning plate have the same inclination. The elastic element is symmetrically installed on the touch plate with the setting position of the push plate as a reference. The elastic element is installed at an inclination between the touch plate and the positioning plate.

[0012] In one embodiment, the elastic element includes an end shaft that is rotatably mounted on a positioning plate, an inner shaft that is telescopically provided inside the end shaft, a compression spring with an outer diameter larger than the inner diameter of the end shaft is sleeved on the inner shaft, and the inner shaft is connected to the contact plate.

[0013] The propulsion component has the same structure as the elastic component, and its end shaft and inner shaft are respectively connected to the abutment plate and the positioning plate.

[0014] In one embodiment, the abutment plate and the contact plate are connected by a central shaft. The abutment plate is sleeved on the central shaft by sleeves provided at its left and right ends, while the contact plate is sleeved on the central shaft by a rotating cylinder provided between the two sleeves. Several anti-collision strips are installed on part of the rotating cylinder structure.

[0015] Several anti-collision strips are installed at equal intervals on the touch plate and the push plate.

[0016] In one embodiment, the abutment plate and the connecting plate are rotatably connected by an inner rod. The abutment plate and the connecting plate are respectively sleeved on the inner rod by a sleeve and an outer cylinder. Several anti-collision strips are also installed on the sleeve on the abutment plate.

[0017] In one embodiment, the bottom sleeve is embedded in a mounting base plate, and the mounting base plate has a slot adapted to fit the bottom sleeve.

[0018] Compared with the prior art, this utility model provides a ground stop device for electromechanical transportation in coal mines, which has the following beneficial effects:

[0019] In the technical solution disclosed in this utility model, the buffer component and the pushing component constituting the buffer adjustment assembly generate a dual buffering effect on the mine car. First, while the buffer component generates a buffering effect using the elastic component, it can pull the pushing component to participate in the action on the side wall or top of the mine car. Thus, the pushing force or friction force generated by the pushing component structure on the mine car reduces the buffering effect generated by the compression spring alone, reducing the dependence on the compression spring while increasing the safety of the mine car deceleration under the dual action.

[0020] By utilizing the same structure but different installation methods for the elastic and propulsion components, this utility model generates different forces with different intervention times for the contact plate and the abutment plate, thereby enhancing the effectiveness of the system when the mine car enters the ground barrier's range.

[0027] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Figures 1-4This is one embodiment of the present invention, and the specific problem addressed by this embodiment is: mine car safety. The applicable working conditions often require the mine car to operate on uphill or downhill slopes. When it is necessary to stop the mine car in a safe and reasonable position, a ground stop is needed to impede the movement of the transport device. This is similar to the solution described in the Chinese patent "A Ground Stop Device for Coal Mine Transport." However, this solution still has some shortcomings. Because the impact force exerted by the mine car on the ground stop has many uncontrollable factors, using only a spring for buffering can easily lead to problems due to the single spring coefficient. When the spring strength is high, the ground stop can easily cause the mine car to experience a relatively strong reaction force at the moment of contact with the mine car. When the spring strength is low, the buffering effect is poor, and the mine car is prone to sideslip when it collides with the ground stop, which can also cause safety accidents.

[0030] Based on the above, this solution proposes a ground stop device for coal mine electromechanical transportation. It utilizes the buffer component 21 and the pushing component 22 constituting the buffer adjustment component 2 to generate a dual buffering effect on the mine car. First, while the buffer component 21 generates a buffering effect using the elastic component 214, it can also pull the pushing component 22 to participate in the action on the side wall or top of the mine car. Thus, the pushing force or friction force generated by the structure of the pushing component 22 on the mine car reduces the buffering effect generated by the compression spring alone, reducing the dependence on the compression spring while increasing the safety of the mine car deceleration under the dual action.

[0031] A specific type of coal mine electromechanical transport ground stop device includes a mounting base plate 1, on which a buffer adjustment component 2 and a pusher component 3 connected to the buffer adjustment component are provided. The buffer adjustment component 2 consists of a buffer component 21 and a pusher component 22. The buffer component 21 is rotatably mounted on the bottom of the pusher component 22. That is, firstly, the buffer component 21 contacts the mine car and generates compression, using the force to reduce the impact force of the mine car. Then, during the gradual buffering process, the buffer component 21 pulls on the pusher component 22, causing it to abut against the top surface of the mine car body. Thus, the friction force generated by the pusher component 22 on the mine car body reduces the speed of the mine car. The pusher component 3 includes a positioning seat 31 disposed on the mounting base plate 1. A positioning plate 32 is obliquely mounted on the positioning seat 31. An elastic member 214 is disposed between the contact plate 213 and the positioning plate 32 and rotates on the positioning plate 32.

[0032] The buffer component 21 includes two symmetrically arranged base sleeves 211, which are embedded in the mounting base plate 1. The mounting base plate 1 has slots adapted to fit the base sleeves 211. Push plates 212 are slidably mounted inside both base sleeves 211. Contact plates 213 are rotatably mounted on the two push plates 212. An elastic element 214 is installed between the contact plate 213 and the rear push component 3. The contact plate 213 has the same inclination as the positioning plate 32. The elastic element 214 is symmetrically mounted on the contact plate 213 with the position of the push plate 212 as a reference. The elastic element 214 is installed at an inclination between the contact plate 213 and the positioning plate 32. The elastic element 214 includes an end shaft that is rotatably mounted on the positioning plate 32. An inner shaft is telescopically mounted inside the end shaft. A compression spring with an outer diameter larger than the inner diameter of the end shaft is sleeved on the inner shaft. The inner shaft is connected to the contact plate 213.

[0033] The pusher 22 includes a push plate 221 that is connected to the contact plate 213. The push plate 221 is rotatably connected to the contact plate 213. A connecting plate 222 that is connected to the push plate 212 is provided on the push plate 221. The push plate 221 and the connecting plate 222 are rotatably connected by an inner rod 5. The push plate 221 and the connecting plate 222 are respectively sleeved on the inner rod 5 by a sleeve 224 and an outer cylinder 225. Several anti-collision strips are also installed on the sleeve 224 provided on the push plate 221. A pusher 223 and an elastic element 214 are installed between the abutment plate 221 and the positioning plate 32. The pusher 223 is configured with the same structure but different installation methods. This allows for the adaptation of different forces when the contact plate 213 and the abutment plate 221 intervene at different times, thereby enhancing the effectiveness of the pusher 223 in entering the ground stop range. The pusher 223 and the elastic element 214 have the same structure. Their end shaft and inner shaft are respectively connected to the abutment plate 221 and the positioning plate 32. The abutment plate 221 and the contact plate 213 are connected by a central shaft 4. The abutment plate 221 is sleeved on the central shaft 4 by sleeves 224 set at its left and right ends. In this design, the diameter of the sleeve 224 is larger than that of the central shaft 4. That is, when the drive motor is coaxially installed on the central shaft 4, it can mainly control the rotating drum 215, which is interference-fitted with the central shaft 4, to rotate. The contact plate 213 is sleeved on the central shaft 4 via a rotating cylinder 215 positioned between two sleeves 224. Several anti-collision strips are installed on a portion of the rotating cylinder 215, and these strips are evenly spaced on both the contact plate 213 and the push plate 212. The control method of this invention is automatic control via a controller. The controller's control circuit can be easily programmed by those skilled in the art, and the power supply is common knowledge in the field. Furthermore, since this invention is primarily used to protect mechanical devices, the control method and circuit connections will not be explained in detail here.
