Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1-4As shown, this specific embodiment adopts the following technical solution: it includes a mine car body 1; the mine car body 1 is rotatably mounted on a track;

[0027] It also includes:

[0028] Support frame 2, which is fixed on the ground, and electric push rod 3 is fixed on the horizontal bar of support frame 2. The front and rear ends of the movable seat 4 are movably sleeved on the vertical bar of support frame 2. The output end of electric push rod 3 is connected to movable seat 4. Electric push rod 3 is connected to an external power source. Several support frames 2 are set in positions prone to derailment. When abnormal movement of the mine car body 1 is detected, electric push rod 3 is activated.

[0029] The contact frame 5 is installed on the left side of the movable seat 4 using the connecting component 6. The crossbar of the contact frame 5 is in contact with the mine car body 1. The position of the contact frame 5 is controlled by the electric push rod 3 so that the crossbar of the contact frame 5 contacts the mine car body 1. The crossbar of the contact frame 5 is fitted with an anti-collision pad 18, which is in contact with the mine car body 1 to improve the impact resistance of the crossbar of the contact frame 5.

[0030] Two buffer tube frames 7 are symmetrically fixed on the vertical rods of the support frame 2. Two abutment rods 8 are movably inserted into the top of the buffer tube frame 7, and the abutment rods 8 are set to abut against the vertical rods of the abutment frame 5. The air pressure intensity inside the buffer tube frame 7 is changed by the pressure of the abutment frame 5. Support rods 15 are fixed on the bottom ring wall of the two buffer tube frames 7, and the support rods 15 are bolted to the ground to improve the impact resistance of the abutment rods 8 and prevent the buffer tube frame 7 from bending and deforming due to the force of the abutment rods 8. Air pressure detectors 16 are provided on the ring wall of the two buffer tube frames 7, and the sensing end of the air pressure detectors 16 is set inside the buffer tube frame 7 to monitor the air pressure inside the buffer tube frame 7 at all times to prevent air leakage and affect the buffering effect. Protective pads 17 are provided on the abutment rods 8. The protective pads 17 are set to abut against the vertical rods of the abutment frame 5 to a certain extent to protect the abutment plate and the abutment frame 5.

[0031] Limiting rod 9, there are two limiting rods 9, and they are respectively movably inserted into the bottom end of the buffer tube frame 7. The bottom end of the limiting rod 9 is fixed with an anti-derailment plate 10. The air pressure in the buffer tube frame 7 acts on the limiting rod 9, and the rollers in the mine car body 1 are prevented from derailing by using the gas buffering effect.

[0032] Connection component 6 includes:

[0033] The connecting plate 11 has a plug plate 12 fixed on its right side. The plug plate 12 is movably inserted into the groove of the movable seat 4. The abutment frame 5 is screwed onto the left side of the connecting plate 11 by a spring-loaded rotating rod. The plug plate 12 serves as a temporary fixation, making it easy to temporarily install the connecting plate 11 on the movable seat 4 and to easily disassemble and assemble the abutment frame 5.

[0034] A number of fixing screws 13 are provided, and each screw passes through the side wall of the movable seat 4 and is threaded onto the insert plate 12 to fix the insert plate 12 onto the movable seat 4.

[0035] Handles 14, there are two handles 14, and they are symmetrically fixed to the top of the connecting plate 11 to facilitate the transfer of the connecting plate 11 and the insert plate 12.

[0036] When using this utility model, when the sensor detects abnormal movement of the mine car body 1 on the track, the electric push rod 3 is activated. The electric push rod 3 pushes the moving seat 4 down, and the moving frame drives the contact frame 5 down, moving the contact frame 5 to a suitable height. When the right end of the mine car body 1 contacts the anti-collision pad 18, the mine car body 1 drives the contact frame 5 to rotate counterclockwise. The contact frame 5 contacts the contact rod 8, and the contact frame 5 squeezes the contact rod 8. The contact rod 8 retracts into the buffer tube frame 7. The air pressure in the buffer tube frame 7 buffers the impact force on the contact frame 5. At the same time, when the contact rod 8 retracts into the buffer tube frame 7, the air pressure intensity in the buffer tube frame 7 is increased. The increased air pressure intensity is used to provide greater stress to the anti-derailment plate 10 through the limit rod 9. When the roller in the mine car body 1 contacts the anti-derailment plate 10, it is easy to restrict the roller on the track to avoid derailment.

[0037] In addition, operators should periodically unscrew the fixing screw 13, remove the connecting plate 11 and the insert plate 12 through the handle 14, and replace or repair the contact frame 5 to avoid damage to the contact frame 5, which would affect the blocking effect on the mine car body 1.

[0038] Compared with the prior art, the beneficial effects of this utility model are:

[0039] By using the cooperation of the contact frame 5 and the contact rod 8, and through the action of air pressure, the impact force of the mine car body 1 is buffered. Then, by using the cooperation of the limit rod 9 and the anti-detachment plate 10, the rollers of the mine car body 1 are prevented from leaving the track.

[0040] The connecting component 6 is set up, and the connection state between the insert plate 12 and the movable seat 4 is adjusted by the fixing screw 13. Then, the connecting plate 11 is installed on the movable seat 4 by the handle 14, which facilitates the periodic disassembly and assembly of the contact frame 5.

[0041] The support rod 15 is installed to improve the impact resistance of the bottom end of the buffer tube frame 7 and prevent the buffer tube frame 7 from bending and being damaged.

[0042] A pressure detector 16 is installed to monitor the air pressure inside the buffer tube rack 7 and prevent air leakage from occurring in the buffer tube rack 7.

[0043] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
