Problems solved by technology

[0002] In order to ensure the safety of rail transportation in coal mines, a three-stop device on one slope is often used to prevent sports car accidents on mine cars. The three-stop device on one slope includes a car stopper on the platform, a car stopper at a position slightly larger than one body length under the slope change point, and a car stopper at the bottom of the slope. The car barrier, one slope and three gears can only reduce the hazards of the mine car sports car; when the staff mistakenly removes the latch or the latch accidentally disengages during the movement of two adjacent cars, the mine car will still cause a sports car accident and cause a safety hazard

Embodiment 1

[0031] Example 1: Please refer to figure 1 , figure 2 with image 3 , the present embodiment discloses a mine car with safe braking, including a car board 5 and wheels 6, at least one end of the car board 5 in the forward direction is fixed with a connecting seat, and a vertical perforation is provided on the connecting seat, the car board 5 The bottom of the car is provided with a moving bar 3, and one end of the moving bar 3 is equipped with a rectangular frame 4, and the rectangular frame 4 is enclosed within the connecting seat of the car plate 5.

[0032] One end of the moving rod 3 far away from the rectangular frame 4 is horizontally connected to the adjacent ends of the two connecting rods 1 respectively. The middle parts of the two moving rods 3 are connected by the first elastic member 2 , and the ends of the two connecting rods 1 away from each other are horizontally rotatably connected with a sliding rod 7 .

[0033] The positions corresponding to the two slidi...

Embodiment 2

[0043] Embodiment two: if Figure 4 , Figure 5 with Image 6 As shown, this embodiment discloses a mine car with safety braking, its structure is roughly the same as that of Embodiment 1, the difference is that this embodiment also includes a brake 9, and the brake 9 includes a seal at one end Sleeve 93, one end of sliding rod 7 stretches in the sleeve 93, is provided with second elastic member 94 in the sleeve 93, and the outer side of sleeve 93 is provided with long groove along its length direction, and slide rod 7 corresponds long groove The position of the fixed limit block 91, the sleeve pipe 93 can move along the length direction of the slide bar 7, the limit block 91 limits the range that the sleeve tube 93 moves along the slide bar 7, and the inner wall of the limit groove 8 is arc-shaped.

[0044] In this embodiment, the second elastic member 94 is a spring or a rubber elastic block.

[0045] Preferably, the number of limiting groove 8 is one.

[0046] Preferabl...

Embodiment 3

[0055] Embodiment three: as Figure 4 with Figure 5 As shown, this embodiment discloses a mine car with safety braking, its structure is roughly the same as that of Embodiment 2, the difference is that the casing 93 of this embodiment is made of metal; the casing 93 of metal is resistant to Good abrasiveness, increase the service life of the casing 93.

Abstract

The invention discloses a mine car with safe braking, comprising a car plate and wheels, a connecting seat is fixed at the end of the car plate in the forward direction, a moving rod is arranged under the car plate, and a rectangular frame is installed at one end of the moving rod. The frame is sleeved on the connecting seat of the car board, and the end of the moving rod away from the rectangular frame is connected horizontally with the end of the two connecting rods, respectively, and the included angle between the moving rod and the connecting rod is an acute angle, and the middle part of the two moving rods passes through. The first elastic piece is connected, the ends of the two connecting rods away from each other are horizontally connected with sliding rods, and the positions of the bottom side of the vehicle board corresponding to the two sliding rods are fixed with fixed blocks. The fixed block is slidably connected, and there are several limit slots on the inner side of the car board that are adapted to the sliding rods; when the staff mistakenly removes and hangs the latch or the latch accidentally disengages during the movement of the adjacent two cars, the wheels are restricted from rotating to avoid sports car accidents. occur, reducing security risks.

Description

technical field [0001] The invention relates to the technical field of mine car protection equipment, in particular to a safety braking mine car. Background technique [0002] In order to ensure the safety of rail transportation in coal mines, a three-stop device on one slope is often used to prevent sports car accidents on mine cars. The three-stop device on one slope includes a car stopper on the platform, a car stopper at a position slightly larger than one body length under the slope change point, and a car stopper at the bottom of the slope. The car barrier, one slope and three gears can only reduce the hazards of the mine car sports car; when the staff mistakenly removes the latch or the latch accidentally disengages during the movement of two adjacent cars, the mine car will still cause a sports car accident and cause a safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects an...
