[0035] During the specific planar excavation operation of the mine, due to the imperfect of the chute system, the shovel-truck and the rail transport electric locomotive jointly carry out the slag planar loading, which becomes the main way of transporting slag. However, due to the complex underground operation environment of the mine, the light is dim, the smoke is diffused, which causes the shovel-truck driver's vision to be greatly limited, and it is difficult to accurately stop the shovel-truck at the best slag unloading position of the electric locomotive car. Once the driver makes a mistake, the shovel-truck is easy to collide with the electric locomotive car.
[0036] The traditional method to solve this problem is to pour concrete car stopping wall. However, after the concrete car stopping wall completes its mission, it needs to be removed by blasting. The removal process not only consumes a lot of time, manpower, and blasting materials such as explosives, but also needs protection during blasting, which significantly increases the construction cost and damages the surrounding rock structure of the roadway, causing safety hazards to subsequent operations. In addition, the concrete car stopping wall is fixed at one place, which permanently blocks the access of the shovel-truck, seriously reducing the flexibility and convenience of the operation
[0037] In view of the above problems, the embodiment of the present application provides an active car stopping device, which can prevent the shovel-truck from colliding with the electric locomotive car when the shovel-truck approaches the electric locomotive car, reduce the risk of equipment damage, protect the safety of the operation personnel, and improve the safety of the mine transportation operation.
[0038] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.
[0039] Fig. 1 is a structural schematic diagram of an active car stopping device in the embodiment of the present application;
[0040] Fig. 2 This is a schematic diagram of a pulley support plate in an embodiment of this application;
[0041] Fig. 3 This is a schematic diagram of the usage structure of the movable vehicle blocking device in the embodiments of this application.
[0042] See Figs. 1-3 A movable vehicle-stopping device includes: a vehicle-stopping structure and a vehicle-stopping fixing device.
[0043] The vehicle-stopping structure includes: a log structure 1 and a pulley support plate 2.
[0044] The log structure 1 consists of three logs tightly bound together by steel ropes.
[0045] In this embodiment, three high-quality round logs with a diameter of 25cm are selected as the log structure 1. The three logs are bound and fixed in layers with steel ropes. The first layer consists of two logs placed horizontally parallel to each other. The second layer consists of one log placed centered directly above the first layer. High-strength steel ropes are then used to bind the logs at both ends and the middle. Each end of the log is bound with three steel ropes spaced 5cm apart, and the middle is bound with two steel ropes spaced 8cm apart, ensuring that the three logs are tightly connected to form a stable and sturdy log structure 1.
[0046] The pulley support plate 2 includes a pulley 201 and a support plate 202. The pulley 201 is installed below the support plate 202, and the round wooden structure 1 is fixedly installed on the support plate 202.
[0047] Specifically: Limiting baffles 203 are provided on both sides of the support plate 202, and fixing holes 2031 are provided on the limiting baffles 203; the round wooden structure 1 is fixedly installed on the support plate 202 by passing a rope through the fixing holes 2031.
[0048] Specifically: the limiting baffle 203 is provided with a limiting threaded hole 2032; a limiting screw 204 is provided in the limiting threaded hole 2032, and a limiting baffle 2041 is provided at the top of the limiting screw 204 to limit the round wood structure 1 in the horizontal direction.
[0049] In this embodiment of the application, by setting the limiting baffle 203, the round timber structure 1 can be limited in the horizontal direction, and by setting the limiting baffle 2041, the round timber structure 1 can be fixed in the horizontal direction, so as to prevent shaking when the pulley support plate 2 moves, ensuring the stable installation of the round timber structure 1 on the support plate 202 and improving construction safety.
[0050] The vehicle-stopping device includes: a bollard 3 and a fixing rope 4.
[0051] The hanging pole 3 is installed on the side of the roadway 5. A hanging ring is provided on the top of the hanging pole 3. One end of the fixing rope 4 is connected to the hanging ring, and the other end of the fixing rope 4 is connected to the round wooden structure 1, so as to fix the vehicle blocking structure in the roadway 5 by the fixing rope 4.
[0052] Specifically: the hanging pole 3 is an inverted wedge type hanging pole 3.
[0053] In this embodiment, a 20mm diameter, 1.8m long inverted wedge-shaped hanging pile is inserted into the borehole, and a special hammering tool is used to hammer the hanging pile so that the inverted wedge structure of the hanging pile is fully opened and tightly embedded into the rock mass of tunnel 5.
[0054] Specifically: the two ends of the fixing rope 4 are equipped with wire rope locking devices so that the position of the vehicle blocking structure can be fixed by adjusting the length of the fixing rope 4.
[0055] In this embodiment, during the connection between the hanging pole 3 and the log structure 1, the length of the steel rope is adjusted by the wire rope locking device so that the vehicle blocking structure just touches the ground and is placed horizontally in the tunnel 5. When the loader 6 needs to unload slag, the vehicle blocking structure can effectively block the loader 6 from continuing to move forward, avoiding collision between the loader 6 and the locomotive bucket. At the same time, when the loader 6 needs to enter or exit the passage, the operator only needs to untie the fixing rope 4 and move the vehicle blocking structure away to keep the passage unobstructed.
[0056] When the tunneling area is completed and the vehicle blocking device needs to be moved to a new work area, except for the hanging pile rod 3 which cannot be removed and recycled, the other components, together with the vehicle blocking structure, are moved to the new work area and reinstalled according to the above installation steps, so that the vehicle blocking device can be reused.
[0057] The technical solution provided in this application may include the following beneficial effects:
[0058] The movable vehicle blocking device of this application can effectively and promptly block the advance of the loader 6 when it approaches the locomotive bucket, avoid collision between the loader 6 and the locomotive bucket, reduce the risk of equipment damage, protect the lives of operators, and significantly improve the safety of mining transportation operations.
[0059] This application presents a movable vehicle-stopping device that eliminates the need for dismantling after each use, saving on the protective and blasting material costs required for demolition. Simultaneously, it avoids damage to the rock structure of roadway 5 caused by dismantling the concrete vehicle-stopping wall, reducing subsequent maintenance costs for roadway 5. Furthermore, the installation and dismantling of this movable vehicle-stopping device only requires connecting and disconnecting steel cables, eliminating the need for complex construction techniques and large machinery, thus improving the flexibility and convenience of mining operations, shortening the construction cycle, and increasing operational efficiency.
