Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of stall protection devices, and more specifically, it relates to a stall protection device for trackless rubber-wheeled vehicles. Background Technology
[0002] Trackless rubber-tired vehicles are specialized vehicles used for transporting personnel and materials in underground engineering projects such as mines and tunnels. Because they use rubber tires instead of tracks, they offer greater flexibility and adaptability. However, during tunnel operation, trackless rubber-tired vehicles are prone to loss of control due to factors such as speeding, gear shifting failure, and brake failure, which can lead to serious safety accidents. Therefore, a stall protection device is needed to ensure personal safety during accidents.
[0003] For example, application number 202221918081.X proposes a stall protection device for a trackless rubber-tired vehicle, which includes a ground, a speed measuring mechanism, a first protection mechanism, and a second protection mechanism. The ground is provided with a first through hole and a second through hole. The speed measuring mechanism includes a bracket and several speed measuring cameras. The first protection mechanism includes two first crossbars, two connecting blocks, and a steel wire rope. The second protection mechanism includes a support plate, a U-shaped piece, two second crossbars, two support pieces, and two auxiliary pieces.
[0004] Based on existing technology, most existing stall protection devices directly intercept and protect the vehicle body by means of rigid blocking. However, because the vehicle body has inertia during stalling, the protection device is susceptible to large impact forces while rigidly intercepting the vehicle body, making it easy to be damaged. Utility Model Content
[0005] To address the aforementioned technical problems, this disclosure relates to a stall protection device for trackless rubber-tired vehicles. This addresses the issue that existing stall protection devices typically rely on rigid blocking to directly intercept and protect the vehicle body. However, because the vehicle body retains inertia during stalling, the protection device is susceptible to significant impact forces while rigidly blocking the vehicle, leading to its easy damage.
[0006] The first aspect of this disclosure provides a stall protection device for trackless rubber-tired vehicles, achieved through the following specific technical means:
[0007] A stall protection device for a trackless rubber-tired vehicle includes: a side support frame; an adjusting screw rotatably connected inside the side support frame; a displacement block slidably connected inside the side support frame, and the displacement block is threaded onto the adjusting screw; a blocking side plate slidably connected to the side support frame, and the blocking side plate is fixed to the top of the displacement block by screws; an intermediate support frame fixedly connected to the side support frame; a side retaining block fixedly connected to the displacement block; a rope take-up rod rotatably connected inside the side retaining block; a rope retaining hole provided on the rope take-up rod; and a blocking rope wound around the rope take-up rod, which blocks... The end of the rope is fixed in the rope insertion hole; a top cover plate is inserted into the top of the intermediate fixing frame; the displacement block is a cuboid structure with a threaded through hole in the middle, and there are two sets of displacement blocks; the side fixing block is a cuboid structure with cylindrical grooves evenly spaced inside, and the cylindrical grooves inside the side fixing block are connected by shaft holes, and the cylindrical grooves inside the side fixing block are connected to circular through holes, and there are two sets of side fixing blocks; the blocking rope is a rope structure with a fixing block at the end.
[0008] In at least some embodiments, the side support frame is configured as a cuboid structure with a hollow interior. A rectangular through hole is provided at the edge of the side support frame, and shaft holes are provided on the upper and lower sides of the side support frame. An arc-shaped through hole is provided on the top of the side support frame, and a locking plate is provided on the outer wall of the side support frame. There are two sets of side support frames.
[0009] In at least some embodiments, the adjusting screw is configured as a threaded rod structure with a cylindrical protrusion on it. A torsion motor is connected to the top of the adjusting screw, and the torsion motor is fixed to the side bracket by screws. There are two sets of adjusting screws.
[0010] In at least some embodiments, the shielding side panel is configured as an arc-shaped plate structure with arc-shaped protrusions, and there are two sets of shielding side panels.
[0011] In at least some embodiments, the interlocking frame is configured as a U-shaped frame, and rectangular grooves are equidistantly provided on the top of the outer wall of the interlocking frame.
[0012] In at least some embodiments, the rope-retracting rod is configured as a cylindrical rod structure, with a rotating handle at the top and an annular groove on the outer wall of the rope-retracting rod; there are two sets of rope-retracting rods in total; the rope-fixing insertion hole is configured as a circular through hole.
[0013] In at least some embodiments, the top cover is configured as a U-shaped cover, and rectangular protrusions are equidistantly provided on the inner wall of the top cover.
[0014] The stall protection device for trackless rubber-tired vehicles proposed in this utility model has the following beneficial effects:
[0015] 1. A shielding side plate and a top cover plate are provided. The shielding side plate is fixed to the top of the displacement block with screws, which facilitates the position adjustment under the action of the adjusting screw. At the same time, the side frame can be extended and retracted to facilitate the shielding of the edge opening of the side frame. By inserting the top cover plate into the top of the side frame, it is convenient to work with the side frame to maintain the sealing of the device in the retracted state, so as to prevent gravel from falling into the device when idle.
[0016] 2. A side-fixed catch block and a barrier rope are installed. The side-fixed catch block is fixed to the displacement block to facilitate synchronous movement with the displacement block. The catch rope rod is rotatably connected to the side-fixed catch block, which allows the barrier rope to be tensioned by rotating the catch rope rod. After tensioning, the barrier rope intercepts the vehicle body and extends a certain distance upon contact with the vehicle body. Then, after reaching the rope limit, it is tensioned again and connected to the vehicle body to intercept it. This creates a buffer to reduce the inertia of the vehicle body, thereby preventing the vehicle from stalling while protecting itself. Attached Figure Description
