Description

Technical Field

[0001] This utility model relates to the field of protection device technology, and in particular to a mine cage support protection device. Background Technology

[0002] In mine shaft hoisting systems, the cage is the core equipment for the vertical transportation of personnel and materials. Its operational safety is directly related to the life safety of underground workers and production efficiency. Existing cage support devices mostly adopt integrated welded or bolted structures, resulting in large equipment size and excessive weight. In narrow mine tunnels or complex geological conditions, equipment transportation requires specialized lifting equipment, which is inefficient and costly. Especially in emergency repair scenarios, the extended downtime caused by difficult disassembly and assembly may lead to secondary safety hazards and restrict the mine's emergency response capabilities. To ensure structural strength, traditional cage support devices are generally made of solid steel or heavy plates, resulting in excessive equipment weight, increasing the load on the headframe and energy consumption. At the same time, the closed bottom plate design is prone to water and gas accumulation, which accelerates metal corrosion in the humid mine environment and reduces the service life of the equipment. In addition, the lack of ventilation design may cause harmful gases to accumulate under the bottom plate, threatening the health of workers.

[0003] Therefore, in order to address this problem, this utility model provides a protective device for mine cage support. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a mine cage support protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mine cage support protection device, comprising a fixed base, a movable strip slidably connected to the side of the fixed base, a movable base provided on the side of the movable strip, a plurality of fixed railings equidistantly arranged on the top of the fixed base and the movable base, side seats symmetrically arranged on both sides of the fixed railings, an adjusting telescopic rod snapped between two of the side seats, and a first base plate and a second base plate respectively placed on the top of the movable strip and the fixed base.

[0006] Preferably, the adjusting telescopic rod passes through both ends of the side seat and is connected to a limit ring by a thread, the limit ring being used for limiting.

[0007] Preferably, the inner wall of the fixed railing is provided with a groove, which is used to reduce the overall weight.

[0008] Preferably, the surfaces of the first base plate and the second base plate are provided with a plurality of fixing grooves at equal intervals, the fixing grooves being used for ventilation.

[0009] Preferably, the adjusting telescopic rod is located on the side of the first base plate and the second base plate, and the adjusting telescopic rod does not contact the first base plate and the second base plate.

[0010] Preferably, the fixed base has a groove inside that matches the movable strip.

[0011] Compared with the prior art, this utility model provides a mine cage support protection device, which has the following beneficial effects:

[0012] 1. This mine cage support protection device, through its modular design of a fixed base, movable strip, movable base, fixed railing, side seat, and adjustable telescopic rod, enables rapid assembly and disassembly of each component. The sliding connection between the movable strip and the fixed base, the snap-fit ​​structure between the adjustable telescopic rod and the side seat, and the independent placement design of the first and second base plates allow workers to easily disassemble the device during transportation or storage, significantly reducing its size and weight. In the complex working environment of mines, this feature can significantly improve equipment handling efficiency, especially in emergency repairs or space-constrained roadways, facilitating rapid deployment and retrieval, shortening maintenance downtime, and ensuring production continuity.

[0013] 2. This mine cage support protection device achieves lightweight design while ensuring overall structural strength by creating grooves on the inner wall of the fixed railings and fixing grooves on the surfaces of the first and second base plates. The grooves effectively reduce the weight of the fixed railings, reducing the difficulty of installation and handling; the fixing grooves not only further reduce the weight of the base plates, but also prevent water and air accumulation through ventilation, avoiding the formation of a damp environment or accumulation of harmful gases under the base plates, reducing the risk of equipment corrosion, and ensuring the dryness and safety of workers' feet.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Reference Figures 1-3 A protective device for a mine cage includes a fixed base 1. A groove is formed on the side of the fixed base 1, through which a movable bar 2 is slidably connected to the fixed base 1, ensuring that the movable bar 2 can slide stably on the side of the fixed base 1. A movable base 3 is provided on the side of the movable bar 2 by welding or fixing with bolts, so that the movable base 3 can adjust its position as the movable bar 2 moves. On the top of the fixed base 1 and the movable base 3, a number of fixed railings 4 are provided at equal intervals by welding or integral molding, which provide support and protection. The function is to fix side seats 6 symmetrically welded on both sides of the fixed railing 4, and to snap the two ends of the adjusting telescopic rod 7 between the two side seats 6. The first base plate 9 and the second base plate 10 are respectively placed on the top of the movable strip 2 and the fixed base 1. When it is necessary to disassemble or carry, the staff can directly remove the first base plate 9 and the second base plate 10 from the movable strip 2 and the fixed base 1, and at the same time release the snap between the adjusting telescopic rod 7 and the side seats 6, and slide the movable strip 2 out of the slide groove of the fixed base 1, thereby realizing the disassembly of each component and making it convenient to carry.

[0021] The adjusting telescopic rod 7 has external threads at both ends passing through the side seat 6, and the limiting ring 8 has internal threads that match the external threads. By rotating the limiting ring 8, it is threaded to both ends of the adjusting telescopic rod 7, which serves to limit the movement and prevent the adjusting telescopic rod 7 from sliding out of the side seat 6, thus ensuring the stability of the device structure.

[0022] The fixed railing 4 is made by casting or cutting, and a groove 5 is opened on its inner wall. The shape of the groove 5 can be rectangular, trapezoidal or other shapes according to the actual design. By opening the groove 5, the overall weight is effectively reduced while ensuring the structural strength of the fixed railing 4, which facilitates the installation and transportation of the device.

[0023] The first base plate 9 and the second base plate 10 are made of metal sheets, and several fixing grooves 11 are opened at equal intervals on their surfaces by means of stamping or cutting. The shape of the fixing grooves 11 can be circular, square, etc. These fixing grooves 11 play a role in ventilation during the use of the device, which can reduce the weight of the base plate.

[0024] In this design, after the adjusting telescopic rod 7 is installed on the side seat 6 between the fixed railings 4, the adjusting telescopic rod 7 is located on the side of the first base plate 9 and the second base plate 10, and the adjusting telescopic rod 7 maintains a certain distance from the first base plate 9 and the second base plate 10 and does not come into contact. This design can avoid the adjusting telescopic rod 7 from interfering with the first base plate 9 and the second base plate 10 and ensure the normal operation of each component of the device.

[0025] The fixed base 1 has a groove that matches the movable bar 2 through machining. The size and shape of the groove are precisely machined according to the design of the movable bar 2 to ensure that the movable bar 2 can slide smoothly in the groove, while ensuring the stability and accuracy of the sliding, so that the movable base 3 can be adjusted in position according to actual needs.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
