[0002] Currently, hydraulic props for mining are key equipment used in underground mining operations such as coal mines to support the roof and maintain the safety of the working space. During the production process, manual movement and handling are required. However, the existing mobile handling equipment has an overly simple structure, resulting in insufficient stability during handling. If a single hydraulic support tilts or shifts during movement, it is prone to tipping over or slipping, which could cause injury to external objects or workers. Utility Model Content

[0003] The purpose of this utility model is to provide a single hydraulic prop moving device for mining, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a single hydraulic support moving device for mining, comprising a base plate, a fixed plate installed on the top left side of the base plate, a limiting groove formed in the middle of the right side of the fixed plate, a double-ended screw installed inside the limiting groove via a bearing, limiting sliders movably installed at both the front and rear ends of the double-ended screw, a moving plate provided at both the front and rear ends of the right side of the fixed plate, a limiting plate provided at both the top and bottom ends of the right side of the moving plate, a fixed rod installed on the opposite side of the limiting plate at both the front and rear ends, the left end of the fixed rod connected to the moving plate, and the side of the limiting slider away from the limiting groove connected to the left side of the moving plate.

[0005] Preferably, a rotating hole is provided on the rear side of the inner cavity of the limiting slide groove, and a single-phase motor is installed on the rear side of the fixing plate at the position opposite to the rotating hole. The rear end of the double-headed screw passes through the rotating hole and is electrically connected to the single-phase motor. The inner cavity of the base plate has a hollow structure, and a baffle is installed on the rear side of the base plate. A storage battery is installed in the inner cavity of the base plate and is electrically connected to the single-phase motor. The single-phase motor is equipped with a switch.

[0006] Preferably, the limiting plates are V-shaped when viewed from above, and several rubber protrusions are installed on the inner side of the limiting plates. An inclined groove is provided on the right side of the top of the base plate.

[0007] Preferably, an operating lever is installed on the upper left side of the fixing plate, a number of pulleys are equidistantly installed on the bottom of the base plate, and a rubber pad is installed on the top of the base plate.

[0008] Preferably, the top of the fixed plate has a movable slot, and a movable support rod is slidably installed in the inner cavity of the movable slot. A limit baffle is installed on the right side of the top of the movable support rod. The limit baffle has an inverted L-shaped structure. A tension spring in a stretched state is sleeved on the outside of the movable support rod. The bottom end of the tension spring is connected to the bottom end of the movable support rod, and the top end of the tension spring is connected to the top end of the inner cavity of the movable slot.

[0009] Preferably, a limiting opening is provided at the bottom left side of the inner cavity of the movable slot, a limiting spring block is installed at the bottom left side of the movable frame rod, and a notch is provided at the relative position of the limiting spring block.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention, when limiting the movement of a single hydraulic prop, can not only limit and fix single hydraulic props of different sizes, but also improve the stability during the limiting movement process by limiting in different directions, as well as increase the applicability and reduce limitations during the limiting process. It avoids the situation where it is impossible to limit hydraulic props of different sizes during use, resulting in only one size being able to move, which would have obvious limitations during movement and use. In addition, the rubber protrusions used for limiting increase the friction force, which can also prevent excessive force during limiting and squeezing, thus avoiding leaving marks on the outside of the hydraulic prop.

[0014] Please see Figure 1-3 This utility model provides a technical solution: a single hydraulic support moving device for mining, including a base plate 1, a fixed plate 2 installed on the top left of the base plate 1, a limiting groove 10 opened in the middle of the right side of the fixed plate 2, a double-headed screw 11 installed inside the limiting groove 10 through a bearing, a limiting slider 12 movably installed at the front and rear ends of the double-headed screw 11, a moving plate 5 provided at the front and rear ends of the right side of the fixed plate 2, a limiting plate 3 provided at the top and bottom ends of the right side of the moving plate 5, a fixed rod 4 installed on the opposite side of the front and rear limiting plates 3, the left end of the fixed rod 4 connected to the moving plate 5, and the side of the limiting slider 12 away from the limiting groove 10 connected to the left side of the moving plate 5.

[0015] A rotating hole is provided on the rear side of the inner cavity of the limiting slide groove 10. A single-phase motor 13 is installed on the rear side of the fixing plate 2 at the position opposite to the rotating hole. The rear end of the double-headed screw 11 passes through the rotating hole and is electrically connected to the single-phase motor 13. The inner cavity of the base plate 1 is hollow. A baffle is installed on the rear side of the base plate 1. A battery is installed in the inner cavity of the base plate 1 and is electrically connected to the single-phase motor 13. The single-phase motor 13 is equipped with a switch. The limiting plate 3 has a V-shaped structure when viewed from above. Several rubber protrusions are installed on the inner side of the limiting plate 3, and a sloping groove is opened on the right side of the top of the base plate 1. An operating lever is installed on the upper left side of the fixed plate 2, and several pulleys are installed at equal intervals on the bottom of the base plate 1. A rubber pad is installed on the top of the base plate 1. The specific implementation method is as follows: During the movement, the hydraulic single support is moved to the upper end of the bottom plate 1 through the inclined groove. Then, the single-phase motor 13 is started to drive the double-headed screw 11 to rotate inside the limiting slide groove 10. At the same time, the limiting slider 12 is driven to move to the opposite side inside the limiting slide groove 10, which drives the moving plate 5 to move. The moving plate 5 drives the limiting plate 3 to move, so that the limiting plate 3 contacts and squeezes the outside of the single hydraulic support for limiting and fixing.

[0016] The top of the fixed plate 2 has a movable slot 7. A movable support rod 6 is slidably installed in the inner cavity of the movable slot 7.

A notch is provided at the relative position of the limiting spring block 15. The specific implementation method is as follows: Before moving, press the limiting spring block 15 to separate it from the limiting port 14, so that the movable frame rod 6 loses its restraint. The pulling spring 8, which is in a stretched state, drives the movable frame rod 6 to move upward, which in turn drives the limiting baffle 9 to move upward. After the support column moves to the upper end of the bottom plate 1 and is limited, press the movable frame rod 6 to move downward, which drives the limiting baffle 9 to move downward. The bottom right end of the limiting baffle 9 is directly stuck on the upper right end of the support column for further limiting and blocking. After the movable frame rod 6 moves downward, the limiting spring block 15 is connected with the inner cavity of the limiting port 14 for further limiting and fixing.
