Description

Technical Field

[0001] The utility model relates to the field of car arresters, and more specifically, to a car arrester with electric driving assistance. Background Art

[0002] The car blocker, also known as the parking device, is one of the important facilities in the coal mine transportation system. It is a device to prevent runaway cars and is generally installed at the top of the slope to avoid accidents.

[0003] After searching, the existing patent (publication number: CN213109341 U) discloses a track car blocker, including a rotating shaft arranged under the track, a car blocker arranged on the rotating shaft, two sliding holes are provided on the car blocker, and slide bars are slidably arranged in the two sliding holes, and the ends of the two slide bars facing the mine car are rotatably provided with a rotating frame, and springs are sleeved on the two slide bars; a rotating roller is arranged between the branches of the two rotating frames; an iron block that can be attracted by an electromagnet is slidably arranged on the bracket, a traction line is arranged under the iron block, and a rocker arm is connected to the lower end of the traction line, and the rocker arm is arranged on the rotating shaft. Under the normal state of the utility model, due to the gravity of the rocker arm, the car blocker is vertical, and the lower end of the mine car is blocked by the car blocker and cannot reach the mine exit; only when the cage reaches the mine exit, the induction sensor senses that the electromagnet is energized, and the rocker arm is driven to rotate upward through the iron block and the traction line, so that the car blocker is flipped to a height where the mine car can pass; avoiding the occurrence of danger. The inventor discovered the following problems in the prior art during the implementation of the utility model:

[0004] Most of the existing car blockers are used on the slopes of the mining area to prevent accidents caused by the loss of control of the mining car. Most of the existing car blockers have a buffering function. During the buffering process, the blocking block will be displaced. During the displacement process, the blocking block is prone to fall off. Therefore, a blocking mechanism is required to facilitate stable blocking. At the same time, the above-cited patent documents do not propose relevant solutions to solve the problem of stable blocking of the car blocker.

[0005] Therefore, in order to solve the above problems, a vehicle arrester with electric assistance is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a vehicle arrester with electric drive assistance to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vehicle blocker driven by electric assistance, comprising a fixing frame, the upper end of which is fixedly connected to a blocking mechanism, the blocking mechanism comprising a fixing block, one end of which is fixedly connected to a first fixing rod, the outer wall of which is wound with a spring, and the outer wall of which is sleeved with a flip block;

[0008] The upper end of the flip block is fixedly connected with a blocking block, the outer wall of the blocking block is connected with an electric push rod via a rotating shaft, one end of the electric push rod is connected with a clamping block via a rotating shaft, and the fixed block is fixedly installed on the fixing frame.

[0009] Preferably, the upper end of the fixing frame is fixedly connected with a track, the outer wall of the fixing frame is fixedly connected with a linkage mechanism, and the outer wall of the fixing frame is fixedly connected with a protective mechanism.

[0010] Preferably, the upper end of the clamping block is connected to the outer wall of the blocking block via a rotating shaft, and the clamping block is in an L-shape.

[0011] Preferably, the protection mechanism includes a second fixing rod, and the outer wall of the second fixing rod is connected to a support column via a bearing.

[0016] Technical effects and advantages of the utility model:

[0017] 1. Compared with the prior art, this electric-assisted car blocker facilitates stable blocking through the blocking mechanism. When in use, the blocking block can block the roller of the mine car, and the spring can be used for buffering during connection to avoid direct collision and cause excessive damage to the mine car. When the blocking block is blocking, the card block will limit and fix the blocking block at the bottom to avoid the detachment of the blocking block. It is safer to use and can stably intercept.

[0018] 2. Compared with the prior art, this type of electric-assisted car arrester can be protected by a protective mechanism. When the mine car is intercepted at a higher speed, it is prone to rollover. The protective frame protects the mine car on both sides to avoid accidents caused by rollover. At the same time, the protective net can prevent large-scale dumping of goods on the mine car, reducing the scope of damage caused by rollover. BRIEF DESCRIPTION OF THE DRAWINGS
