DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-4 The utility model provides a technical solution: a fixed base of a rake mine winch, including a main body 1, and a plurality of pressure plates 2 are symmetrically hinged on both sides of the upper surface of the main body 1. Fixing holes 4 that match the mounting holes on the base of the rake mine winch are opened on the pressure plate 2 and the main body 1. After the rake mine winch is placed on the main body 1 of the base, the pressure plate 2 is folded toward the base of the rake mine winch. When the lower surface of the pressure plate 2 contacts the base of the rake mine winch, the pressure plate 2 is parallel to the upper surface of the main body 1 as a whole. At this time, the mounting holes on the base of the rake mine winch completely coincide with the fixing holes 4 on the main body 1 and the pressure plate 2. After that, the rake mine winch can be fixed by passing fixing bolts or embedded bolts through the fixing holes 4 and the mounting holes. The operation is simple and the fixation is convenient. When the base body 1 is heavier as a whole or a counterweight is used and the stability is higher, the main body 1 and the scraper winch can be fixed only by fixing bolts. When the base body 1 is lighter as a whole, the stability is lower or the scraper winch requires higher stability, it is necessary to set pre-buried anchor bolts at the fixed position of the scraper winch in advance, and then first pass the anchor bolts through the fixing holes 4 of the main body 1, and then place the scraper winch on the main body 1 and pass the anchor bolts through the mounting holes of its base, and then rotate the pressure plate 2 so that the anchor screw passes through the fixing holes 4 on the pressure plate 2, and finally screw on the nuts to fix it.

[0018] A number of shock-absorbing springs 6 are evenly arranged on the lower surface of the main body 1. The bottom ends of the shock-absorbing springs 6 are fixedly connected to a supporting base plate 5. The supporting base plate 5 is used to support the main body 1 and the rake winch. The shock-absorbing springs 6 can greatly improve the shock-absorbing performance of the rake winch during operation, thereby protecting the rake winch and the base body 1, and reducing working noise, which is beneficial to the health of the staff.

[0019] The four corners of the main body 1 are provided with wheel frame grooves 8, and a wheel frame 9 is rotatably arranged in the wheel frame groove 8, and a roller 10 is rotatably arranged on the wheel frame 9. The side surface of the main body 1 and the side surface of the wheel frame 9 are provided with positioning holes 11, wherein the positioning hole 11 on the wheel frame 9 is provided with one, and the positioning holes 11 on the main body 1 are provided with at least two and at least two positioning holes 11 are distributed in a circular array with the rotation center of the wheel frame 9 as the center. The main body 1 and the rake mine winch can be easily moved by the roller 10, which is convenient for the transportation of the rake mine winch in the tunnel before and after use, thereby improving the flexibility of the rake mine winch. When the rake mine winch is working, the positioning pins in the positioning holes 11 can be taken out and the wheel frame 9 and the roller 10 can be flipped outward or upward, so that the roller 10 does not contact the ground, and the supporting bottom plate 5 is in contact with the ground, thereby improving the stability of the rake mine winch and ensuring the normal operation of the rake mine winch.

[0020] The main body 1 can have two or three positioning holes 11. If two holes are provided, they can be symmetrically arranged above and below the rotation center of the wheel frame 9, or arranged concentrically around the rotation center of the wheel frame 9 at 90° intervals. Locating pins are inserted into the positioning holes 11 to secure the wheel frame 9. If three holes are provided, they can be located above and below the rotation center of the wheel frame 9 and at 90° to the sides. The wheel frame 9 and roller 10 can be rotated to the side or top of the main body 1 according to the specific conditions such as the depth of the roadway floor. The locating pins are made of a high-strength alloy with a diameter slightly smaller than that of the positioning holes 11 to ensure stability when the main body 1 drives the scraper winch.

[0021] According to the preferred technical solution, two slide grooves 12 are symmetrically provided on both sides of the upper surface of the main body 1, and fixed plates 13 for fixing the two ends of the scraper winch are slidingly arranged in the slide grooves 12. The fixed plates 13 can slide back and forth to be suitable for scraper winches of different specifications, thereby improving the universality of the base, and after the scraper winch is placed, the fixed plates 13 can be moved and squeezed to make the scraper winch more firmly fixed.

[0022] Further preferably, a screw 15 is rotatably provided in the chute 12, and a screw hole matching the screw 15 is opened on part of the side surface of the fixed plate 13 in the chute 12. The end of the screw 15 passes through the outer surface of the main body 1 and is fixedly connected to the rotating handle 16. By rotating the handle 16 to drive the screw 15 to rotate, the fixed plate 13 can be driven to move, thereby clamping and fixing the two ends of the rake winch or loosening the rake winch, etc., which is simple to operate, easy to use, and improves work efficiency.

[0023] Optionally, the inner surface of the pressure plate 2 is provided with a pressure plate anti-slip pad 3, and the side surface of the fixed plate 13 is provided with a fixed plate anti-slip pad 14. The pressure plate anti-slip pad 3 and the fixed plate anti-slip pad 14 can improve the fixation firmness of the scraper winch and play a certain buffering and shock-absorbing role; the lower surface of the supporting base plate 5 is provided with a base plate anti-slip pad 7, which is used to improve the overall stability of the scraper winch and the base, and can also further improve the shock-absorbing performance of the base and reduce working noise.
