Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to an automatic parking device for an electric flat car. Background Art

[0002] In the production process of manufacturing enterprises, material reverse transportation is an indispensable link. Usually, manual following or limit switches are used, which often leads to collisions between two vehicles. The existing device mainly reduces the degree of accidents by the displacement of the anti-collision plate. The existing technology is similar to a new automatic parking device for stainless steel electric flat cars. The structure with the patent authorization announcement number CN212289732U includes a car body, a fixed plate is welded on the right side of the bottom of the car body, a photoelectric sensor is fixedly connected to the right side of the fixed plate, and a light-emitting lamp fixedly connected to the fixed plate is provided below the photoelectric sensor. A guide rod is welded on the bottom of the fixed plate, and a movable plate is provided on the outer movable sleeve of the guide rod. A reflector is bonded to the side of the movable plate close to the fixed plate. The utility model is novel in design and simple in operation. It is not only convenient for warning and reminding staff when a vehicle collides, but also can provide buffering to avoid rigid collisions. However, there are still areas that can be optimized in the device.

[0003] Existing devices mainly use elastic components to buffer collision accidents, making it difficult for some devices to brake after being impacted, causing some devices to move a long distance. At the same time, some devices mainly use brake components of fixed specifications, making it difficult for some devices to adjust the active width of the brake mechanism according to the width of the axle, causing some devices to have difficulty in braking flat cars of various specifications, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above technical problems, the present application proposes an automatic parking device for an electric flat car. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an automatic parking device for an electric flat car.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic parking device for an electric flat car, comprising a frame, a wheel axle is movably connected to the middle of the bottom of the frame, a fixing frame is fixedly connected to the right side of the bottom of the frame, an anti-collision plate is inserted on the right side of the bottom of the fixing frame, an adjustment frame is provided inside the left side of the fixing frame, and an adjustment box is fixedly connected to the left side of the fixing frame;

[0006] A braking mechanism is provided below the fixing frame, and the braking mechanism includes a symmetrical telescopic rod, and the right side of the outer wall of the symmetrical telescopic rod is fixedly connected to the left side of the anti-collision plate. An adjusting mechanism is provided inside the adjusting box, and the adjusting mechanism includes a symmetrical screw, and both ends of the symmetrical screw are movably connected to the inner wall of the adjusting box.

[0007] Preferably, both ends of the left side of the symmetrical telescopic rod are fixedly connected to the limiting telescopic rod, and the left end of the limiting telescopic rod is fixedly connected to the right side of the adjustment frame.

[0008] Preferably, a telescopic frame is inserted into the outer side wall of the adjustment frame, and a brake pad is fixedly connected to the outer side of the telescopic frame.

[0009] Preferably, both ends of the symmetrical telescopic rod are movably connected to a damping telescopic rod, the other end of the damping telescopic rod is movably connected to the inner middle part of the telescopic frame, and the outer wall of the damping telescopic rod is fixedly connected to a spring.

[0010] Preferably, a second bevel gear is fixedly connected to the middle of the outer wall of the symmetrical screw, and adjusting screw sleeves are threadedly connected to both sides of the outer wall of the symmetrical screw. The right side of the outer wall of the adjusting screw sleeve passes through the fixing frame and is fixedly connected to the left side of the adjusting frame.

[0011] Preferably, the second bevel gear is meshingly connected with the first bevel gear below, a transmission shaft is fixedly connected to the middle of the bottom of the first bevel gear, and the bottom end of the transmission shaft passes through the adjustment box and is fixedly connected to a twist cover.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model uses the structures of the symmetrical telescopic rod, the limiting telescopic rod, the telescopic frame, the brake pad, the damping telescopic rod and the spring in the braking mechanism. When the anti-collision plate is hit, the symmetrical telescopic rod drives the right end of the damping telescopic rod to slide synchronously and compress the spring. The left end of the damping telescopic rod drives the telescopic frame and the brake pad to slide symmetrically away, so that the brake pad is forced to fit on the inner wall of the wheel disc of the wheel axle, thereby realizing the braking of the wheel axle, so that part of the device can be braked after being hit, effectively avoiding the displacement of part of the device over a long distance, and improving the stability and practicality of the device.

[0014] 2. The utility model adjusts the spacing between the brake pads through the symmetrical screw, the second bevel gear, the adjusting screw sleeve, the first bevel gear, the transmission shaft and the twist cover and other structures in the adjustment mechanism. By rotating the twist cover, the twist cover drives the transmission shaft and the first bevel gear to rotate within a limited position. The meshing of the first bevel gear drives the second bevel gear and the symmetrical screw to rotate within a limited position. The symmetrical screw drives the adjusting screw sleeve, the adjusting frame, the telescopic frame and the brake pad to slide symmetrically, thereby realizing the adjustment of the spacing between the brake pads. This allows some devices to adjust the active width of the brake mechanism according to the width of the wheel axle, which is convenient for braking flat cars of various specifications and improves the adjustability and practicality of the device.
