Description
Technical Field
[0001] The utility model belongs to the technical field of auxiliary equipment for underground inclined tunnels, and in particular relates to a car blocking device for a car-running-away prevention system. Background Art
[0002] Coal mine underground transportation is an important part of coal production, among which inclined tunnel transportation is a common mode of transportation. During the inclined tunnel transportation process, the mine car may run away due to rope breaking, unhooking, etc., which will not only damage the equipment, but also endanger the lives of underground workers. Therefore, the anti-runaway device plays a vital role in the underground transportation system of coal mines.
[0003] In the prior art, the anti-runaway device mainly includes two types: car blocking doors and car blockers. The car blocking door mainly relies on mechanical structure to form a barrier at the exit of the inclined lane to prevent the running car from entering the main lane; the car blocker is set in the inclined lane to prevent the running car from sliding down by friction or other means. However, there are some problems with the traditional car blocking door in practical application: for example, the opening and closing of the traditional car blocking door usually requires manual operation, the starting response speed is slow, and the vehicle cannot be quickly blocked when it loses control, resulting in poor anti-runaway effect; when the traditional car blocking door is in use, a rigid car blocking door is mostly used to block and brake the mine car. However, when the mine car is running at high speed, if the car blocking door is impacted by the mine car during the blocking process, not only the mine car will be damaged, but also the mine car will be easily derailed, thereby affecting the use and transportation efficiency of the mine car.
[0004] Based on this, the utility model proposes a car blocking device for an anti-runaway system with fast response speed and good deceleration and braking effects, so as to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0043] Please refer to the attached Figure 1 To Attachment Figure 7 , the utility model provides a technical solution:
[0044] A vehicle blocking device of an anti-runaway system is arranged in a mine car lane and used in conjunction with a mine car 1 to decelerate and stop the mine car 1, comprising a baffle 3, a guide rod 4, a buffer 5 and a buffer support plate 6; wherein:
[0045] The baffle plate 3 is arranged on a side close to the mine car 1, and a buffer pad 2 is arranged on the outer side of the baffle plate 3 for use with the mine car 1. The buffer pad 2 is arranged on a side close to the mine car 1 with a plurality of buffer protrusions, and the buffer pad 2 plays a role of buffering and decelerating the mine car 1, and the buffer pad 2 is made of rubber material.
[0046] It should be noted that the cushion pad 2 is made of nano energy absorbing material. The cushion pad 2 serves as the first level of cushioning layer. The nano energy absorbing material remains soft when not subjected to force, but becomes hard when subjected to high-speed impact, thereby effectively absorbing external force, showing the characteristics of efficient protection, lightness and comfort.
[0047] The guide rods 4 and the buffers 5 are detachably mounted on the inner side of the baffle 3 in a matrix, and are used in conjunction with the buffer support plate 6 to play a buffering role;
[0048] The buffer support plate 6 is fixedly installed at the tunnel exit through a mounting seat 7;
[0049] In this embodiment, the buffer pad 2 is provided to buffer and decelerate the mine car 1 and protect the baffle 3, so as to avoid the mine car 1 directly acting on the baffle 3 and causing rigid damage to the baffle 3; the buffer 5 is provided to decelerate and stop the mine car 1 when the mine car 1 moves in the tunnel; the guide rod 4 is provided to play a guiding role, so that several buffers 5 can be evenly stressed when subjected to the impact force of the mine car 1, avoiding eccentric stress that affects the structural safety; the mounting seat 7 is provided to form a buffer and speed bump at the tunnel exit to decelerate and stop the mine car 1.
[0050] As a preferred embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 One end of the guide rod 4 is detachably mounted on the baffle plate 3, and the other end passes through a through hole provided on the buffer support plate 6 and moves along the through hole.
[0051] In this embodiment, the movement of the baffle 3 is guided by the arrangement of multiple guide rods 4, so that the baffle 3 can move as a whole toward the direction close to the buffer support plate 6 when subjected to external pressure, thereby ensuring uniform force on multiple buffers 5, avoiding the deceleration effect of the device on the deceleration and braking of the mine car 1 due to uneven force, and at the same time avoiding eccentric damage to the device when the force is uneven.
[0052] As a preferred embodiment, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 , the buffer 5 comprises a piston rod 51, a cylinder 52 and a first spring 53; wherein:
[0053] One end of the piston rod 51 is connected to the baffle 3 via a connecting plate 58, and the other end is provided with a piston 55, which is movably disposed in the cylinder body 52 and in close contact with the inner wall of the cylinder body 52;
[0054] The cylinder body 52 is a sealed cylinder, and a cylinder body end plate 59 is provided at the front end opening of the cylinder body 52. The cylinder body end plate 59 is used in conjunction with the piston rod 51. When in use, the piston rod 51 passes through the central circular hole of the cylinder body end plate 59 and moves along the circular hole. A second spring 57 is also provided in the cylinder body 52. The second spring 57 is provided at the bottom of the cylinder body 52 and is used in conjunction with the piston 55.
[0055] The first spring 53 is movably sleeved on the outside of the cylinder body 52, and the first spring 53 is used in conjunction with a threaded connector 56 threadedly connected to the outside of the cylinder body 52, and the other end is connected to a bottom plate 54 embedded in the buffer support plate 6. When in use, the first spring 53 plays a buffering role.
[0056] In this embodiment, the buffer 5 is installed between the baffle 3 and the buffer support plate 6 by setting the connecting plate 58 and the first spring 53; at the same time, the first spring 53 is used to resist deformation and buffer the external pressure to attenuate the external force, thereby preventing the bottom of the cylinder body 52 from directly hitting the buffer support plate 6 under the action of the external force, thereby playing a buffering and protective role; through the setting of the second spring 57, on the basis of playing the role of resetting the piston 55, it also has a buffering effect to attenuate the force transmitted from the piston rod 51.
[0057] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 A threaded section is also provided on the outer side of the cylinder body 52 , and the threaded section is threadedly connected to the screw connection 56 ; when in use, the screw connection 56 is rotated to adjust its position on the outer side of the cylinder body 52 to apply prestress to the first spring 53 .
[0058] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 In order to play a buffering and damping role, the internal sealed cavity of the cylinder body 52 is also filled with high-pressure hydraulic oil. At the same time, a number of oil holes 521 are evenly opened on the inner wall of the cylinder body 52. The oil holes 521 are connected to the hydraulic oil channels 522 arranged on the side walls of the cylinder body 52.
[0059] In this embodiment, by setting the oil hole 521 and the hydraulic oil channel 522, the high-pressure hydraulic oil in the cylinder body 52 can flow on both sides of the piston 55 to play a buffering and damping role. Under normal conditions, the second spring 57 is extended, and the number of oil holes 521 on the side of the piston 55 close to the cylinder end plate 59 is less than the number of oil holes 521 on the side close to the bottom of the cylinder body 52. Therefore, when the piston rod 51 is subjected to an external force and pushes the piston 55 to move in the cylinder body 52, the hydraulic oil in the rear end chamber of the piston 55 enters the hydraulic oil channel 522 through the rear end oil hole 521, and finally enters the front end chamber of the piston 55 through the oil hole 52 in the front end chamber of the piston 55. The damping effect of the piston 55 when moving in the cylinder body 52 is achieved by the difference in the number of oil holes 521 in the front and rear chambers, so as to play a buffering role and protect the mine car 1.
[0060] At the same time, the elastic force of the first spring 53 is greater than the elastic force of the second spring 57 , so when in use, when the second spring 57 is deformed to the maximum displacement under pressure, the first spring 53 is deformed.
[0061] As a preferred embodiment, please refer to Figure 1 , Figure 2 and Figure 5 The mounting seat 7 is a steel plate structure, and a connecting steel plate 71 is integrally formed at the lower end of the mounting seat 7. The connecting steel plate 71 and the lower end of the mounting seat 7 are connected to the buffer support plate 6 through connecting bolts 61 to form an integral structure; at the same time, the mounting seat 7 is also connected to the side wall at the tunnel exit through a positioning anchor rod 8.
[0062] In this embodiment, by setting a connecting steel plate 71 perpendicular to the steel plate of the mounting seat 7, the detachable connection between the mounting seat 7 and the buffer support plate 6 can be effectively achieved, and the connection effect can be guaranteed, which is convenient for maintenance and replacement; multiple car blocking devices are installed at the tunnel exit by positioning the anchor rod 8, forming a buffer and speed reduction belt at the tunnel exit to slow down and stop the mine car 1.
[0063] The vehicle blocking device of the anti-runaway system of the utility model is suitable for fixed box-type mining vehicles.
[0064] The use process and principle of the anti-runaway system of the utility model include:
[0065] The car blocking device of the anti-runaway system is installed at the turning of the mine car lane. The weight of coal or gangue carried by the mine car 1 is different each time, and the transportation speed of the mine car 1 is different each time. Therefore, the impact force of the mine car 1 passing through the turning of the mine car lane is different.
[0066] In a possible embodiment, the dimensions of the mining vehicle 1 are: 2020 mm in length, 880 mm in width, and 1150 mm in height, and its loading weight is 0.9 T:
[0067] When the mine car 1 slides downward with a relatively low impact force, as shown in Case 1 in Table 1, the impact force acts on the buffer pad 2, and the buffer pad 2 works to buffer and decelerate the mine car 1 and protect the baffle 3 to avoid the mine car 1 directly acting on the baffle 3 and causing rigid damage to the baffle 3.
[0068] When the mine car 1 slides downward with a moderate impact force, as shown in Case 2 in Table 1, the buffer pad 2 and the baffle 3 transmit the external impact force to the buffer 5, driving the piston 55 to move in the cylinder 52, the second spring 57 is compressed, and the hydraulic oil in the cylinder 52 flows, thereby braking the mine car 1.
[0069] When the mine car 1 slides downward from a slightly higher impact force, as shown in Case 3 in Table 1, the impact force acts on the buffer pad 2, and the buffer pad 2 and the baffle 3 transmit the external impact force to the buffer 5, driving the piston 55 to move in the cylinder 52, and the second spring 57 is compressed, and the hydraulic oil in the cylinder 52 flows. At this time, when the compression amount of the second spring 57 is not enough to brake the mine car 1, the first spring 53 is deformed, and the mine car 1 is braked before reaching the maximum displacement of the first spring 53.
