Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coal mine fully mechanized mining equipment, and more specifically, to a hydraulic support orienting device. Background Technology
[0002] Hydraulic supports, as core equipment in fully mechanized coal mining faces, have complex structures and diverse functions, mainly including bases, columns, roof beams, shield beams, pushing devices, and adjustment devices. Among these, the base, as the supporting structure of the hydraulic support, plays a crucial role in transferring roof loads and maintaining support stability. However, in traditional hydraulic support adjustment processes, manual operation or winch traction is typically used. This method is not only cumbersome but also poses significant safety hazards, especially in adjustment operations under complex geological conditions, easily leading to accidents such as support collapse and personnel injuries. Furthermore, traditional adjustment methods are inefficient and cannot meet the requirements of modern coal mines for high-efficiency, low-intensity operations.
[0003] Therefore, it is necessary to improve existing technologies. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example:
[0024] like Figures 1 to 4 As shown, a hydraulic support steering device includes a base 1, a fixed seat 2, a pulling steering beam platform 3, a pulling steering beam 4, and a pulling steering seat 5. The pulling steering beam platform 3 and the fixed seat 2 are both fixedly connected to the base 1. The lower end of the fixed seat 2 is provided with a cavity, and the upper end of the fixed seat 2 is provided with a horizontal sliding hole. A steering pulley II 55 is rotatably provided on the side wall of the fixed seat 2.
[0025] The directional beam 4 is slidably mounted on the directional beam platform 3. A first hydraulic cylinder is installed in the cavity of the fixed base 2 to drive the directional beam 4 to move linearly along the directional beam platform 3. A steering sprocket 6 is rotatably mounted on the directional beam 4. A steering chain 7 is fixedly connected to one side of the fixed base 2. The steering chain 7 cooperates with the steering sprocket 6 and is connected to a hook 8. When the first hydraulic cylinder drives the directional beam 4 to move, the steering chain 7 drives the hook 8 to move.
[0026] The pull-and-shift steering seat 5 includes an outer seat 51 and an inner seat 52 that are slidably connected. The outer seat 51 is slidably engaged with a horizontal sliding hole. A hinge seat 58 is provided at the lower end of the outer seat 51, and a hinge shaft 59 that engages with the hinge seat 58 is provided at the upper end of the pull-and-shift steering beam 4. When the pull-and-shift steering beam 4 moves, the outer seat 51 moves synchronously with the pull-and-shift steering beam 4. A steering pulley I 54 is rotatably mounted on one end of the inner seat 52, and a steering pulley III 56 is rotatably mounted on the base 1. A steel wire rope 57 is fixedly connected to the end of the inner seat 52 near the steering pulley I 54. One end of the steel wire rope 57 is sequentially wound around the steering pulley II 55, the steering pulley I 54, and the steering pulley III 56 and connected to a hook 8. When the pull-and-shift steering beam 4 moves, the displacement ratio of the steel wire rope 57 and the steering chain 7 is different. Therefore, the two hooks 8 can drive the two sides of the hydraulic support to move in a staggered manner, thereby achieving steering.
[0027] A second hydraulic cylinder 53 is provided between the inner seat 52 and the outer seat 51 to drive the inner seat 52 to move linearly along the outer seat 51. The stroke of the wire rope 57 can be controlled independently through the second hydraulic cylinder 53, so as to achieve more precise control of the hydraulic support.
[0028] Preferably, the base 1 includes a steering platform 11, a steering guide platform 12, and a landslide platform 13 connected in sequence. The steering platform 11 and the steering guide platform 12, as well as the steering guide platform 12 and the landslide platform 13, are connected by multiple connecting plates 14 and rollers 15. The two ends of the connecting plates 14 are respectively hinged to the corresponding steering platform 11, steering guide platform 12, or landslide platform 13. Two rollers 15 are provided between adjacent connecting plates 14. The rollers 15 are coaxially arranged with the hinge axis of the connecting plates 14. The resistance when the hydraulic support moves can be reduced by the rollers 15.
[0029] Preferably, the steering guide platform 12 is provided with a number of guide wheels 16 to prevent the hydraulic support from detaching from the base 1 during the movement.
[0030] An auxiliary support connecting plate 17 is fixedly installed on one side of the steering platform 11 and the steering guide platform 12. The auxiliary support connecting plate 17 is used to connect other equipment. Connecting other equipment during operation can prevent the base 1 from moving.
[0031] The upper end of the fixed base 2 is provided with a lifting lug 21 for easy hoisting.
[0032] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
