Description

Technical Field

[0001] The utility model relates to the technical field of mine supports, in particular to a foldable hydraulic support for mines. Background Art

[0002] Mining hydraulic supports are devices used to support the inner wall of a mine to reduce the risk of mine collapse. There are many different types of mining hydraulic supports, which need to be selected based on the actual conditions of the mine.

[0003] However, mining hydraulic supports are mainly designed to support the top of the mine to prevent the roof from collapsing, ensuring the safety of miners and the stability of the mine. However, the use of supports cannot guarantee that the mine will not collapse. Traditional hydraulic supports can only support the mine. If the mine still collapses, the supports will lose their function and will not provide protection for the workers under the mine. Therefore, a new type of mining hydraulic support is needed to solve this problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a foldable hydraulic support for mining, which can provide support for the side of the mine on the basis of providing support for the top of the mine. Once the mine collapses, the hydraulic support can form a passage for people to take shelter, increasing the chance of survival of people underground in the event of a mine disaster.

[0005] The technical solution to achieve the purpose of the utility model is: a foldable mining hydraulic support, including a support plate and a lifting assembly, the support plate is internally slidably connected to two slides, the lifting assembly includes a base, the base is fixedly connected to a support rod, the support rod is fixedly connected to an oil cylinder, the oil cylinder is internally slidably connected to a lifting column and a push plate, the lifting column is fixedly connected to the support plate, the base is fixedly connected to a hydraulic press, the output shaft of the hydraulic press is fixedly connected to the push plate, hydraulic oil is arranged between the push plate and the lifting column, an auxiliary assembly is arranged on the slide, the auxiliary assembly includes a bracket two, four of the bracket twos are respectively fixedly connected to the two slides, and the four bracket twos are rotatably connected to a baffle.

[0006] Preferably, the auxiliary component further includes an oil pipe and a telescopic rod, the two oil pipes are fixedly connected to the oil cylinder, and the two telescopic rods are slidably connected to the inside of the two oil pipes respectively.

[0007] Preferably, the interiors of the two oil pipes are connected to the interior of the oil cylinder, and the two oil pipes and the oil cylinder are perpendicular to each other.

[0008] Preferably, the auxiliary component includes a bracket one, two brackets one are fixedly connected to the two slides respectively, and the ends of the two telescopic rods are rotatably connected to the two brackets one respectively.

[0009] Preferably, the auxiliary component further includes a support plate, two of the support plates are fixedly connected to the inside of the support plate, both support plates are provided with air hole 1, and two air holes 2 are provided at the bottom of the support plate.

[0010] Preferably, the auxiliary component further comprises a magnetic block, four of the magnetic blocks are fixedly connected to the bottom of the support plate, and the four magnetic blocks are connected to the ends of the four baffles.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First: In the present invention, when installing the hydraulic support, the base can be fixed on the ground in the mine, and then the hydraulic press is started. The output shaft of the hydraulic press moves upward, pushing the push plate and squeezing the hydraulic oil. The hydraulic oil is squeezed to cause the lifting column to rise, thereby pushing the support plate upward, so that the support plate is against the top wall of the mine, thereby supporting the top wall of the mine, and while the hydraulic oil is squeezed, the two telescopic rods will also move outward, thereby pushing the two supports to both sides, so that the two slides are pulled out from the inside of the support plate. Since the hydraulic oil in the oil cylinder and the oil pipe is integrated, the moving distance of the telescopic rod and the moving distance of the lifting column will be automatically adjusted, so that the movement of the slide and the support plate can be coordinated.

[0013] Second: In the present invention, when the support plate is against the top wall of the mine, the four baffles can be unfolded. When the slide plate slides out of the support plate and the baffle plate is unfolded, the support plate, the slide plate and the baffle plate can form an arched door. During the unfolding of the baffle plate, a certain space needs to be excavated on the ground of the mine so that the bottom end of the baffle plate can be against the ground of the mine. At this time, the hydraulic support is installed. By installing several hydraulic supports together in sequence and close to each other, a channel composed of hydraulic supports can be formed in the mine. Once the mine collapses, the channel formed by the hydraulic supports can block falling rocks. The falling rocks will block both ends of the hydraulic supports, but the falling rocks will not completely block the channel. Sufficient space will be left in the channel for mine workers to take shelter. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.

[0021] The utility model provides a foldable mining hydraulic support through improvement. The technical solution of the utility model is:

[0022] like Figure 1-Figure 3 As shown, a foldable mining hydraulic support includes a support plate 1 and a lifting assembly 3. The support plate 1 is internally slidably connected to two slide plates 2. The lifting assembly 3 includes a base 31. The base 31 is fixedly connected to a support rod 32. The support rod 32 is fixedly connected to an oil cylinder 33. The oil cylinder 33 is internally slidably connected to a lifting column 34 and a push plate 36. The lifting column 34 is fixedly connected to the support plate 1. A hydraulic press 35 is fixedly connected to the base 31. The output shaft of the hydraulic press 35 is fixedly connected to the push plate 36. Hydraulic oil 37 is provided between the push plate 36 and the lifting column 34. An auxiliary component 4 is provided, which includes a bracket 2 47. Four brackets 2 47 are respectively fixedly connected to two slides 2. The four brackets 2 47 are rotatably connected to baffles 48. The support plate 1 supports the top wall of the mine. The two slides 2 can slide out from the support plate 1. With the unfolded baffle 48, the entire hydraulic support will form an arched channel. By connecting several hydraulic supports together, a sufficiently long channel can be formed. Once the mine collapses, the channel will not be completely blocked by falling rocks, leaving enough space for underground workers to take shelter.

[0023] Furthermore, the auxiliary component 4 also includes an oil pipe 41 and a telescopic rod 42. The two oil pipes 41 are fixedly connected to the oil cylinder 33, and the two telescopic rods 42 are respectively slidably connected to the inside of the two oil pipes 41. When the hydraulic oil 37 is squeezed, it will push the telescopic rod 42 and the lifting column 34, thereby moving the support plate 1 upward, and at the same time the two slides 2 are pulled out from both sides of the support plate 1.

[0024] Furthermore, the interiors of the two oil pipes 41 are connected to the interior of the oil cylinder 33, and the two oil pipes 41 and the oil cylinder 33 are perpendicular to each other. Since the hydraulic oil 37 in the oil cylinder 33 and the oil pipes 41 are integrated, the moving distance of the telescopic rod 42 and the moving distance of the lifting column 34 are automatically adjusted, so that the movement of the skateboard 2 and the support plate 1 can be coordinated.

[0025] Furthermore, the auxiliary component 4 includes a bracket 43, and the two brackets 43 are respectively fixedly connected to the two skateboards 2. The ends of the two telescopic rods 42 are respectively rotatably connected to the two brackets 43. When the telescopic rod 42 and the skateboard 2 move at the same time, the ends of the bracket 43 and the telescopic rod 42 will rotate relative to each other, so a rotational connection is required.

[0026] Furthermore, the auxiliary component 4 also includes a support plate 44, and the two support plates 44 are fixedly connected to the inside of the support plate 1. The two support plates 44 are each provided with an air hole 1 45, and the bottom of the support plate 1 is provided with two air holes 2 46. The main function of the support plate 44 is to improve the stability of the support plate 1 itself. When the skateboard 2 moves in the support plate 1, the air hole 1 45 and the air hole 2 46 are required to circulate air to stabilize the air pressure inside the support plate 1.

[0027] Furthermore, the auxiliary component 4 also includes a magnetic block 49, four magnetic blocks 49 are fixedly connected to the bottom of the support plate 1, and the four magnetic blocks 49 are connected to the ends of the four baffles 48. The magnetic block 49 can absorb the baffle 48. Its main function is to fix the baffle 48 during the installation of the hydraulic support to prevent it from shaking.

[0028] The specific working method is: when installing the hydraulic support, the base 31 can be fixed on the ground in the mine, and then the hydraulic press 35 is started. The output shaft of the hydraulic press 35 moves upward, pushing the push plate 36 and squeezing the hydraulic oil 37. The hydraulic oil 37 is squeezed to make the lifting column 34 rise, thereby pushing the support plate 1 upward, so that the support plate 1 is against the top wall of the mine, thereby supporting the top wall of the mine, and the hydraulic oil 37 is squeezed. At the same time, the two telescopic rods 42 are moved outward, thereby pushing the two brackets 43 to both sides, so that the two slides 2 are pulled out from the inside of the support plate 1. Since the hydraulic oil 37 in the oil cylinder 33 and the oil pipe 41 are integrated, the moving distance of the telescopic rod 42 and the moving distance of the lifting column 34 are automatically adjusted, so that the slide 2 and the support plate The movement of 1 can be coordinated. When the support plate 1 is against the top wall of the mine, the four baffles 48 can be unfolded. When the slide plate 2 slides out of the support plate 1 and the baffles 48 are unfolded, the support plate 1, the slide plate 2 and the baffles 48 can form an arched door. During the unfolding of the baffles 48, a certain space needs to be excavated on the ground of the mine so that the bottom end of the baffle 48 can be against the ground of the mine. At this time, the hydraulic support is installed. By installing several hydraulic supports together in sequence and close to each other, a channel composed of hydraulic supports can be formed in the mine. Once the mine collapses, the channel formed by the hydraulic supports can block falling rocks. The falling rocks will block both ends of the hydraulic supports, but the falling rocks will not completely block the channel. There will be enough space in the channel for the mine workers to take shelter.

[0029] The technical means disclosed in the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
