Mountain tunnel inclined shaft car deceleration blocking device

Abstract

This utility model relates to the technical field of blocking devices, and proposes a car-stopping device for inclined shafts in mountain tunnels. It includes: a fixed base, a track fixedly installed on top of the fixed base, and a blocking assembly disposed on top of the fixed base. The blocking assembly includes two buffer mechanisms, buffer mechanism one and buffer mechanism two, disposed opposite each other on top of the fixed base. Buffer mechanism two is located between the two buffer mechanisms one. Each of the two buffer mechanisms one has an opening mechanism on its top, and a buffer mechanism three is disposed on the opening mechanism. When a car impacts and contacts the rubber plate, the linkage buffer plate pushes two driven rods to slide together on the brake plate, transmitting the impact force to spring two and damper two. With the cooperation of spring two and damper two, the impact force of the car-stopping device is initially buffered. The remaining force after the initial buffering is completely buffered and offset by the cooperation of spring one and damper one, and spring three and damper three, effectively improving the stability of the car-stopping device in the inclined shaft of the mountain tunnel.

Description

Technical Field

[0001] This utility model relates to the technical field of blocking devices, specifically to a sled car blocking device for inclined shafts in mountain tunnels. Background Technology

[0002] In tunnel design, to ensure the construction period, improve tunnel ventilation, ensure drainage, guarantee power supply for construction, and cope with other geological and natural disasters, inclined shaft construction technology is used to solve the problem of long tunnel construction, turning long tunnel construction into "short-distance" construction. Inclined shafts are often characterized by long tunnel bodies and large longitudinal slopes. While facilitating construction, the safety risks of transportation within the inclined shaft become prominent, especially the risk of vehicle slippage. When wheeled vehicles entering or exiting the inclined shaft lose control and exceed speed limits during normal driving due to mechanical system failure, failure to stop them in time will cause greater safety accidents and property losses.

[0003] For example, CN220690013U discloses a tunnel inclined shaft car-stopping device, which relates to the field of stopping devices. It includes a blocking net installed above the tunnel track, with two buffers installed on the ground on both sides of the track connected to the blocking net by ropes. Two anti-overturning mechanisms are installed on one side of the blocking net, and these two anti-overturning mechanisms are located on both sides of the tunnel track. This invention, by setting up a clamping plate, buffer block, main shaft, semi-circular plate, compression block, connecting rod, and second spring, allows the mine car to move when a runaway accident occurs. The mine car will move the blocking net, which will pull the compression block through steel cables, pushing the semi-circular plate upwards. This will cause the main shaft to rotate, thereby pushing the clamping plate outwards through the connecting rod, causing the buffer block to contact the side of the mine car and clamp it. Simultaneously, the second spring prevents the mine car from sliding down, thus preventing the mine car from tipping over, reducing losses, saving costs, and providing a better interception effect.

[0004] However, in implementing the relevant technology, the above-mentioned tunnel inclined shaft car sliding blocking device has the following problems: it is difficult to buffer and block the impact force of the sliding car in multiple ways, which can easily lead to excessive impact of the sliding car, causing damage to the blocking device. In the long run, it is easy to cause instability of the blocking, thereby reducing the safety of the tunnel inclined shaft car sliding blocking. Therefore, a mountain tunnel inclined shaft car sliding blocking device is proposed. Utility Model Content

[0005] This utility model proposes a car-stopping device for inclined shafts in mountain tunnels, which solves the problem in related technologies that it is difficult to provide multiple buffers to block the impact force of the car-stopping, which can easily lead to excessive impact and damage to the blocking device. In the long run, the blocking is unstable, thus reducing the safety of car-stopping in inclined shafts of tunnels.

[0008] The blocking assembly includes two buffer mechanisms, namely buffer mechanism 1 and buffer mechanism 2, which are disposed opposite to each other on the top of the fixed base. The buffer mechanism 2 is located between the two buffer mechanisms 1. Each of the two buffer mechanisms 1 is provided with an opening mechanism on its top, and a buffer mechanism 3 is provided on the opening mechanism.

[0009] Preferably, the two buffer mechanisms include two fixed blocks that are fixedly installed on the top of the fixed base, two sliding rods are fixedly installed between the two fixed blocks, a slider is slidably connected to both sliding rods, and two springs are provided on the two upper sliding rods.

[0012] A gate is fixedly installed on the front side of the turntable, and a locking block is fixedly installed on the bottom of the gate.

[0013] Preferably, the buffer mechanism three includes two driven rods that move through the gate plate, a buffer plate that is fixedly installed at the front end of the two driven rods, a rubber plate that is fixedly installed on the front side of the buffer plate, a connecting plate that is fixedly installed at the rear end of the two driven rods, and a spring two that is respectively sleeved on the two driven rods. The two ends of the spring two are fixedly connected to the connecting plate and the gate plate.

[0017] The second slider and the second slide rod are movable through each other;

[0018] A slot plate is fixedly installed on the top of the second slider.

[0019] The working principle and beneficial effects of this utility model are as follows:

[0020] When the car rolls off, it impacts the rubber plate, and the linkage buffer plate pushes the two driven rods to slide together on the brake plate, so that the impact force is transmitted to spring two and damper two. With the cooperation of spring two and damper two, the impact force of the rolling car is initially buffered. The remaining force after the initial buffering is completely buffered and offset by the cooperation of spring one and damper one, and spring three and damper three, effectively improving the stability of the rolling car blocking in the inclined shaft of the Ling Tunnel.
