[0018] The following combination Figures 1 to 4 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0019] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please combine Figures 1 to 4 As shown, this utility model provides a mining cable winding rack, which includes a mounting frame and a winding drum 4 rotatably mounted on the mounting frame. Wheel plates 5 are fixedly mounted at both ends of the winding drum 4 along its length. A pair of connecting plates 7 are fixedly mounted on the mounting frame, and a fixing plate 6 is fixedly mounted between the two connecting plates 7. A pull rod 9 is slidably mounted on the fixing plate 6, and a pressure plate 10 is fixedly mounted on one end of the pull rod 9. A first spring 12 is fixedly mounted between the pressure plate 10 and the fixing plate 6. When the cable is wound up, the first spring 12 provides an elastic force to the pressure plate 10, so that the pressure plate 10 presses firmly on the cable to prevent the cable from becoming tangled. The side of the pressure plate 10 facing the winding drum 4 is set to be arc-shaped. When the arc surface of the pressure plate 10 presses firmly on the cable, it can prevent the winding drum 4 from rotating and avoid the cable from becoming tangled due to the rotation of the winding drum 4.

[0022] When winding the cable, if the pressure plate 10 presses against the outer surface of the winding drum 4, it will seriously affect the winding of the cable. To solve this problem, a slot 11 is provided on the fixing plate 6, and a plug rod 15 is slidably arranged in the slot 11. A plug hole 17 adapted to the plug rod 15 is provided on the pull rod 9. A limit ring 16 is fixedly installed on the plug rod 15. A mounting plate 13 is fixedly installed on the fixing plate 6. A second spring 14 is fixedly installed between the limit ring 16 and the mounting plate 13. Before winding the cable, pull one end of the pull rod 9 to move the pull rod 9. When the plug rod 15 coincides with the plug hole 17, under the elastic force of the second spring 14, the bottom end of the plug rod 15 passes through the plug hole 17, restricting the movement of the pull rod 9. At this time, the pressure plate 10 is fixed on the outside of the winding drum 4, so it will not affect the winding of the cable. A handle 8 is fixedly installed on one end of the winding drum 4. Rotating the handle 8 can make the winding drum 4 wind up the cable.

[0023] The mounting frame consists of a base frame 1, a handle 2, and support plates 3. The handle 2 is fixedly mounted on the base frame 1. There is a pair of support plates 3, both of which are fixedly mounted on the base frame 1. The winding drum 4 is rotatably mounted between the two support plates 3. When the winding frame is not winding the cable, it is necessary to use the winding frame. It can position the base frame 1 above the wheel plates 5, which are supported on the ground by a pair of wheel plates 5. Workers can push the handle 2 to make the two wheel plates 5 roll on the ground, which can reduce the difficulty of moving the winding frame.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
