Description

Technical Field

[0001] The utility model belongs to the field of coal mine fully mechanized mining equipment, in particular to a walking trolley of a self-moving machine tail system for thin coal seams. Background Art

[0002] With the development of mechanization of coal mining, many medium-thick and thick coal seams suitable for mine mining are gradually decreasing, while my country's medium-thin coal seams are widely distributed. In order to ensure the sustainable use of resources, the mining of thin coal seams has become a hot topic of concern for coal enterprises. The self-moving tail is an important part of the chute transportation equipment of the working face. It is used to connect the bridge transfer machine and the conveyor, and is the guarantee of high production and efficiency of the working face. The thin coal seam self-moving tail is a miniaturized self-moving tail that meets the use requirements of thin coal seam mining. At the same time, it gradually realizes the automation of various functions of the self-moving tail, including automatic adjustment of belt deviation, automatic forward movement of the tail chassis after a cycle of the transfer machine is completed, and automatic straightening of the tail forward direction. The realization of these functions will change the working mode of the self-moving tail, which must be operated by someone, and is one of the important technologies for unmanned working face coal mining.

[0003] During the operation of the traditional self-moving tail, the transfer machine is connected to the walking trolley of the self-moving tail. After the transfer machine completes a stroke cycle, the self-moving tail needs to be moved forward. During the forward movement of the frame, the weight of the transfer machine and the walking trolley are all pressed on the self-moving tail frame, increasing the friction between the self-moving tail frame and the ground, resulting in large resistance to the forward movement of the self-moving tail and difficulty in moving. In addition, during the forward movement of the self-moving tail frame, the traditional self-moving tail is supported by several cylinders on both sides, and the entire self-moving tail is pulled forward by two push cylinders. Many factors such as the large number of cylinders, high difficulty in operation, and heavy structural parts have led to excessively high costs caused by the redundant structural design of the self-moving tail, which is not conducive to the long-term development of enterprises to reduce costs and increase efficiency.

[0004] In the design process of the self-moving tail of the thin coal seam, the machine body is long and the transfer machine is heavy, and the following problems may exist:

[0005] 1. The weight of the self-moving tail machine is 17 tons, and the weight of the transfer machine is 10 tons. The weight of the transfer machine is pressed on the self-moving tail machine. When it is pulled forward directly, the friction resistance is large, which will cause wear and tear on the self-moving tail machine and affect the life of the self-moving tail machine.

[0006] 2. When the body of the self-moving tail machine is lifted, the weight of the transfer machine is pressed on the self-moving tail machine, and the cylinder needs to lift the weight of the transfer machine and the self-moving tail machine. Therefore, a large number of lifting cylinders are designed, resulting in a high manufacturing cost of the self-moving tail machine.

[0007] 3. During the operation of the self-moving tail, there is a motor and reducer on one side of the transfer machine, which often causes the transfer machine to tilt to one side. Utility Model Content

[0008] The utility model aims to provide a walking trolley for a self-moving tail system of a thin coal seam, so as to solve the problems of a heavy frame of the self-moving tail, large moving resistance, difficult tail movement and dumping of the transfer machine.

[0009] The utility model adopts the following technical scheme: a walking trolley for a self-moving tail system of a thin coal seam, the left and right sides of the walking trolley are placed on the upper side of the frame of the self-moving tail system, the upper side of the walking trolley carries a transfer machine, the transfer machine is used to transfer the coal on the working face to the belt of the frame and then transport it to the front end; the walking trolley can move forward along the frame and is used to drive the transfer machine to move forward to complete the mining of the thin coal seam;

[0010] The traveling trolley includes:

[0011] The load-bearing plate is horizontally arranged and located on the upper side of the frame, and is used to fix the transfer machine thereon;

[0012] Two sliding plates, the upper sides of which are respectively fixedly connected to the left and right sides of the bearing plate, and the lower sides of which extend downward and extend into the area between the frame and the guide rails fixed to the frame;

[0013] The two front wheels are respectively fixed on the outer sides of the sliding plate, and the lower sides of the two front wheels are placed on the guide rails, so that the traveling trolley moves on the guide rails.

[0014] Furthermore, it also includes:

[0015] The two rear wheels are respectively fixed on the outer sides of the sliding plate and are at a predetermined distance from the front wheels. The lower sides of the rear wheels are placed on the guide rails, and then cooperate with the front wheels to enable the traveling trolley to move on the guide rails.

[0016] Furthermore, a heightening plate is fixedly connected to the middle of the supporting plate, and the lower side of the heightening plate is fixedly connected to the supporting plate. The heightening plate is used to raise the fixed height of the transfer machine, thereby avoiding interference with the movement of the transfer machine on the left and right sides of the frame after the transfer machine is installed.

[0017] The beneficial effects of the utility model are:

[0018] The utility model relates the walking trolley to the frame and the guide rails. When the self-propelled machine tail moves, the traveling board originally located on the roadway ground can be pulled up, thereby avoiding the friction between the traveling board and the ground, and facilitating the traveling board to move forward easily. Moreover, the walking trolley can move forward on the frame through the front wheels and the rear wheels. Since the transfer machine is pressed on the frame, it cannot be guaranteed that the tail can move forward easily. At this time, the utility model is propped up to make it separate from the frame guide rails. In this way, the weight of the transfer machine head is completely transferred to the traveling board. At this time, when the mobile tail is moved, it can be easily moved forward.

[0019] The utility model can make the overall structure of the self-moving tail simple and reduce the number of oil cylinders, which can effectively reduce the production cost of the self-moving tail and improve the economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS
