Technical Field
[0001] This application relates to the technical field of mine transportation equipment, and particularly relates to a collision-type automatic hook-on and unhook device. Background Art
[0002] With the rapid development of China's economy, the demand for various resources has been increasing year by year, especially for various mineral resources. As mining enterprises continuously improve production efficiency, the popularization of automation is urgent. At present, in the production process of mining enterprises, the connection and disconnection operations between locomotives and mine cars are mostly carried out manually, which is time-consuming and laborious, and affects production efficiency and the development of automated transportation work.
[0003] In the prior art, automatic hook-on and unhook devices usually require a complex automated drive structure to complete the operations of automatic unhooking and automatic hook-on. However, due to problems such as complex structure, high preparation cost, and inconvenient control, such automatic hook-on and unhook devices have not been widely used. In addition, after the hook-on operation is completed by the existing automatic hook-on and unhook devices, the formed hook cannot swing flexibly, making the device unable to adapt to turning, further restricting the application of the existing automatic hook-on and unhook devices. During the connection process between the locomotive and the mine car, collisions are likely to occur when the locomotive approaches the mine car. If automatic hook-on can be directly achieved through collision, it will be beneficial to simplify the structure and control method of the automatic hook-on and unhook device to meet the actual application requirements.
[0004] In view of this, it is necessary to provide an improved collision-type automatic hook-on and unhook device to solve the above problems. Summary of the Invention

[0032] The automatic connection of mining transportation equipment has always been a matter of concern in the mining field. Currently, the hook-unhooking operations of the connection devices of the mine car 4 and the electric locomotive 3 generally need to be completed manually.
[0033] In order to solve the technical problem that it is difficult to achieve stable and accurate automatic connection of mining transportation equipment, the present application provides a collision-type automatic hook-unhooking device. Among them, by colliding the grab hook 15 with the connection channel steel 2 of the mine car, and using the raising and falling of the grab hook 15, the hooking operation is completed, and the electric push rod 11 drives the grab hook 15 to rise to complete the unhooking operation, so as to realize the automatic connection and separation of the electric locomotive 3 and the mine car 4.
[0034] The following further elaborates on the present application in combination with specific embodiments.
[0035] Please refer to Figure 1 and Figure 3 The present application provides a collision-type automatic hook-unhooking device, including: a hook-unhooking mechanism 1 arranged at the rear end of the electric locomotive 3 and a connection channel steel 2 of the mine car arranged at the front end of the mine car 4. The hook-unhooking mechanism 1 includes an electric push rod 11, a lifting plate 12, a first rotating assembly, a second rotating assembly, and a grab hook 15; one end of the lifting plate 12 far from the connection channel steel 2 of the mine car is connected to the electric push rod 11, and one end of the lifting plate 12 close to the connection channel steel 2 of the mine car is connected to the grab hook 15 through the second rotating assembly; the first rotating assembly includes a first rotating shaft 131 rotatably connected to the lifting plate 12, and the axial direction of the first rotating shaft 131 is parallel to the horizontal plane.
[0036] In the above manner, the lifting plate 12 can rotate around the first rotating shaft 131. When the grab hook 15 collides with the connection channel steel 2 of the mine car, the grab hook 15 can rotate upward around the first rotating shaft 131 to form a raised state, and then fall downward around the first rotating shaft 131 under the action of gravity. By using the raising and falling of the grab hook 15, the hooking operation can be completed. When the unhooking operation needs to be performed, by contracting the electric push rod 11, one end of the lifting plate 12 is pulled downward, so that the lifting plate 12 drives the grab hook 15 to rise when rotating around the first rotating shaft 131, and the unhooking operation is completed, thereby realizing the automatic hook-unhooking of the electric locomotive 3 and the mine car 4.
[0037] Further, in the embodiment of the present application, as Figure 3 and Figure 5As shown, the first rotating assembly further includes a first fixing plate 133 for fixing the first rotating shaft 131, and a first shaft sleeve 132 sleeved outside the first rotating shaft 131 and rotatably connected to the first rotating shaft 131; the first fixing plate 133 is arranged outside the battery locomotive 3, and the lifting plate 12 is rotatably connected to the first rotating shaft 131 through the first shaft sleeve 132. Through the rotational movement between the first shaft sleeve 132 and the first rotating shaft 131, the grab hook 15 can freely tilt up and fall back when colliding with the connecting channel steel 2 of the mine car. To ensure that the grab hook 15 can freely tilt up and fall back, the first shaft sleeve 132 needs to have sufficient self-lubricity or be regularly lubricated. In addition, each mine can choose whether to install a spring on the first fixing plate 133 according to different working conditions, so that the hook unhooking mechanism 1 can quickly return to the correct position after turning.
[0038] Further, in the embodiment of the present application, as Figure 3 and Figure 5 shown, the second rotating assembly includes a second rotating shaft 141, a second fixing plate 143 for fixing the second rotating shaft 141, and a second shaft sleeve 142 sleeved outside the second rotating shaft 141 and rotatably connected to the second rotating shaft 141; the second fixing plate 143 is connected to the lifting plate 12, and the axial direction of the second rotating shaft 141 is perpendicular to the horizontal plane. The grab hook 15 is connected to the second shaft sleeve 142 through a grab hook adjusting plate 16. The rotational movement between the second shaft sleeve 142 and the second rotating shaft 141 can drive the grab hook adjusting plate 16 and the grab hook 15 to rotate left and right around the second rotating shaft 141, so that the grab hook 15 can swing left and right along with the turning of the battery locomotive 3 to adapt to the turn.
[0039] Further, in the embodiment of the present application, as Figure 3 shown, the grab hook adjusting plate 16 is arranged on both sides of the grab hook 15, and the grab hook 15 is connected to the grab hook adjusting plate 16 through a bolt 161. A slot 162 for the movement of the bolt 161 is horizontally opened on the grab hook adjusting plate 16. By adjusting the fastening position of the bolt 161 in the slot 162, the extending distance of the grab hook 15 can be adjusted.
[0040] Further, in the embodiment of the present application, as Figure 3 shown, a notch 121 is provided on the lifting plate 12, the electric push rod 11 is connected to the lifting plate 12 through an electric push rod connecting shaft 111, the electric push rod connecting shaft 111 is placed in the notch 121, the notch 121 is arc-shaped, and the center of the circle corresponding to the notch 121 is the center of the cross-section of the first rotating shaft 131. Through the up and down linear movement of the electric push rod 11, the lifting plate 12 can be driven to rotate around the first rotating shaft 131 along the direction of the notch 121. At the same time, the size of the notch 121 of the lifting plate 12 can control the rotation angle of the lifting plate 12, so as to control the tilting angle and distance of the grab hook 15.
[0041] Further, in the embodiment of the present application, as Figure 1As shown, the electric push rod 11 is fixed inside the battery locomotive 3 through the electric push rod fixing device 112, and an opening for the lifting plate 12 to pass through is provided at the rear end of the battery locomotive 3. The first fixing plate 133 is connected to the battery locomotive fixing plate 17, and the first rotating assembly is fixed outside the battery locomotive 3 through the battery locomotive fixing plate 17.
[0042] Further, in the embodiment of the present application, as Figure 2 shown, an inclined surface with a sufficient inclination angle is provided at the lower part of the end of the grab hook 15 close to the mine car connecting channel steel 2, and the inclined surface of the grab hook 15 can ensure that the grab hook 15 can be normally lifted when being impacted.
[0043] The working process of the collision type automatic hook-on and hook-off device provided by the present application is roughly as follows:
[0044] 1. Hook-on process
[0045] When hooking on, the mine car 4 moves forward along the track 5. After meeting the battery locomotive 3, the grab hook 15 impacts the mine car connecting channel steel 2 and tilts upward. As Figure 2 shown, after tilting upward, due to the action of gravity, the grab hook 15 falls downward and slews the mine car connecting channel steel 2 to complete the hook-on operation.
[0046] 2. Hook-off process
[0047] The telescopic end of the electric push rod 11 contracts inward, so that the electric push rod connecting shaft 111 connected to the electric push rod 11 drives the lifting plate 12 to move downward along the notch 121, and the grab hook 15 tilts upward and returns to the Figure 2 state. At this time, the battery locomotive 3 drives away from the connection position, the mine car connecting channel steel 2 is disengaged from the grab hook 15, the telescopic end of the electric push rod 11 extends outward and returns to the original position, and the grab hook 15 follows and returns to the initial position to complete the hook-off operation.
[0048] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and the embodiments with the same structure and the same function and effect as the technical idea within the technical solution scope of the present application are all included in the technical scope of the present application. In addition, within the scope not departing from the gist of the present application, various deformations that can be thought of by those skilled in the art are applied to the embodiments, and other ways constructed by combining some constituent elements in the embodiments are also included in the scope of the present application.
