Abstract
Description
Technical Field
[0001] This utility model belongs to the field of safety support technology, specifically relating to a mobile safety support for mining operations. Background Technology
[0002] In non-coal underground mining operations, drilling and charging are typically carried out directly beneath the ore body or rock mass roof, facing various safety hazards such as rockfalls and landslides. Traditional safety supports mainly consist of a base for workers to stand on and a protective canopy on top of the base. When rocks fall, the canopy can intercept them to prevent them from hitting workers. However, in existing technology, the protective canopy is generally arc-shaped or conical. When rocks fall onto the canopy, they scatter in all directions, lacking an effective guidance mechanism. When the rocks fall in the direction of the work, they need to be moved, increasing the burden on the workers. Utility Model Content
[0003] To address the above problems, the purpose of this utility model is to provide a mobile safety support for mining operations, thereby solving the problems mentioned in the background section.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a mobile safety support for mining operations, comprising a stable base for workers to stand on during construction, and a protective structure installed above the stable base by a height adjustment component for preventing falling rocks. The protective structure includes a load-bearing part for receiving falling rocks and a guide part disposed on the side of the load-bearing part away from the stable base, which aims to guide falling rocks on the load-bearing part to the ground away from the direction of construction.
[0005] The beneficial effects of this utility model are as follows: The mobile safety support of this utility model, by setting a protective structure including a bearing part and a guide part, can effectively receive and guide falling rocks that fall on the bearing part, keeping them away from the direction of construction advancement, ensuring that workers do not work directly under the open sky, greatly reducing the risk of construction workers being hit by falling rocks, and improving the safety of operation.
[0006] To prevent secondary damage to the construction area from falling rocks, the protective effect of the scaffolding has been improved:
[0007] As a further improvement to the above technical solution: the guide part is a single structure with a cross-section designed as a right triangle to effectively guide the direction of falling rocks.
[0008] The beneficial effects of this improvement are as follows: the guide section is designed with a single structure and a right-angled triangular cross section, that is, the guide section is a sloped surface that is inclined to the side away from the direction of construction. This design can accurately and effectively guide the direction of falling rocks, prevent falling rocks from causing secondary damage to the construction area, and improve the protective effect of the support.
[0009] To ensure more even stress distribution on the protective structure, the guiding effect of falling rocks and the stability of the protective structure are enhanced:
[0010] As a further improvement to the above technical solution: the number of guide parts is two, and the shape of the cross surface of the guide parts is an obtuse triangle.
[0011] The beneficial effects of this improvement are as follows: by setting two guide sections with an obtuse triangular cross-section, the falling rocks that land on the bearing section will fall along the two guide sections to the side away from the direction of construction, making the stress on the protective structure more uniform and enhancing the guiding effect of the falling rocks and the stability of the protective structure.
[0012] To prevent falling rocks from threatening the direction of construction:
[0013] As a further improvement to the above technical solution: the guide part is conical in shape, and four guide parts are formed around the protective structure, wherein a side baffle is provided on the guide part closer to the construction forward direction.
[0014] The beneficial effects of this improvement are as follows: The guide section is conical in shape and forms four guide slopes around the protective structure. A side baffle is installed on the guide section near the construction direction. Two slopes are symmetrically arranged on the side of the side baffle near the guide section. The falling rocks that fall on the guide section near the construction direction are guided along both sides of the slope guide support. The side away from the guide section is perpendicular to the receiving part, which can prevent the falling rocks from falling in the construction direction. This design further optimizes the guidance and protection effect of falling rocks, so that the falling rocks can be guided more smoothly to the ground away from the construction area. At the same time, the side baffle can also prevent the falling rocks from threatening the construction direction.
[0015] In order to reduce the burden on the protective structure and extend its service life:
[0016] As a further improvement to the above technical solution, a buffer assembly is added between the protective structure and the height adjustment component to improve the compressive strength of the protective structure.
[0017] The beneficial effects of this improvement are as follows: the addition of a buffer component between the protective structure and the height adjustment component significantly improves the compressive strength of the protective structure. When falling rocks impact the protective structure, the buffer component can absorb part of the impact force, thereby reducing the burden on the protective structure and extending its service life. The height adjustment component can be a hydraulic cylinder or other height adjustment mechanism, which can facilitate the adjustment of the height of the protective structure.
[0018] In order to improve the compressive strength of the protective structure:
[0019] As a further improvement to the above technical solution: the buffer assembly includes a mounting seat disposed between the protective frame and the height adjustment component, and having multiple buffer cavities evenly arranged inside it, and a buffer component welded inside the buffer cavity and having a movable column fixedly connected to the protective frame at its top.
[0020] The beneficial effects of this improvement are as follows: when the protective structure is subjected to external pressure, a downward external force is applied to the movable column, causing it to slide downward along the buffer cavity and compress the buffer component. The buffer component can be a spring. Under the elastic action of the spring, the external force is buffered, thereby improving the compressive strength of the protective structure, extending the service life of the protective structure, and further protecting the safety of workers.
[0021] To facilitate the flexible movement and positioning of the support during the mining process:
[0022] As a further improvement to the above technical solution: the bottom of the stable base is provided with a driving device, which facilitates the flexible movement and positioning of the support during the mining process.
[0023] The beneficial effects of this improvement are as follows: A drive device is installed at the bottom of the stable base. The drive device can be a protective cylinder fixedly installed at the bottom of the stable base, a support plate installed inside the protective cylinder via a hydraulic cylinder, and traveling wheels fixedly installed on both sides of the protective cylinder. When the support needs to be moved, the hydraulic cylinder drives the support plate to retract into the protective cylinder, and the traveling wheels contact the ground, applying external force to the support and driving the traveling wheels to rotate, thus enabling the support to move forward. The traveling wheels can also be electrically driven. When the support needs to be stopped, the hydraulic cylinder drives the support plate to extend out of the protective cylinder, and the support plate contacts the ground, which can prevent the support from shifting during construction. This allows the support to move and be positioned flexibly during mining operations. This design not only improves construction efficiency but also allows the support to be quickly adjusted in position as needed to adapt to different construction environments and conditions.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0033] This utility model relates to a mobile safety support for existing mining operations. It mainly includes a stable base 1 for workers to stand on during construction, and a protective structure 3 installed above the stable base 1 via a height adjustment component 2 to prevent rockfalls. In existing technologies, the protective structure 3 is typically an arc-shaped or conical protective canopy. In use, the stable base 1 is moved to the area to be worked on, and workers stand on the stable base 1 under the protective canopy, ensuring that workers do not work directly under an open ceiling. This is an introduction to existing mobile safety supports for mining operations.
[0034] As can be seen from the above, the existing mobile safety supports for mining have the following defects when in use. In the existing technology, the protective shed is generally arc-shaped or conical. When rocks fall on the protective shed, they scatter in all directions. There is no effective mechanism to guide the falling rocks. When they fall in the direction of construction, the rocks need to be moved away, which increases the burden on construction personnel. Based on the above problems, this utility model adopts the following improvement method to solve them.
[0035] like Figure 1-7As shown, a mobile safety support for mining includes a stable base 1 for workers to stand on during construction, and a protective structure 3 installed above the stable base 1 via a height adjustment component 2 to prevent falling rocks. The protective structure 3 includes a load-bearing part 4 for receiving falling rocks and a guide part 5 located on the side of the load-bearing part 4 away from the stable base 1, designed to guide falling rocks onto the load-bearing part 4 to the ground away from the direction of construction. This mobile safety support, by providing the protective structure 3, including the load-bearing part 4 and the guide part 5, can effectively receive and guide falling rocks onto the load-bearing part 4. By keeping it away from the direction of construction, the risk of workers being hit by falling rocks is greatly reduced, improving operational safety. The height of the protective structure 3 can be flexibly adjusted using the height adjustment component 2 to adapt to different mining depths and terrain conditions. This design allows the safety support to be widely used in various mining operations, improving its practicality and adaptability. The design of the stable base 1 gives the entire safety support good stability and mobility. During mining operations, workers can easily move the safety support as needed to adapt to different work positions and conditions, improving work efficiency.
[0036] Furthermore, such as Figure 1-2 As shown, this is the first embodiment of the present invention. The guide part 5 is designed as a right-angled triangular cross-section with a single structure. That is, the guide part 5 is a slope that is inclined to the side away from the direction of construction. This design can accurately and effectively guide the direction of falling rocks, prevent falling rocks from causing secondary damage to the construction area, and improve the protective effect of the support.
[0037] Furthermore, such as Figure 3-4 As shown, this is the second embodiment of the present invention. By setting two guide parts 5, and the cross-sectional shape of the guide parts 5 is an obtuse triangle, the falling rocks that fall on the bearing part 4 are dropped along the two guide parts 5 to the side away from the construction direction, so that the force on the protective structure 3 is more uniform, and the guiding effect of the falling rocks and the stability of the protective structure 3 are enhanced.
[0038] Furthermore, such as Figure 5-6 As shown, this is the third embodiment of the present invention. The guide part 5 is conical in shape and forms four guide slopes around the protective structure 3. A side baffle 6 is provided on the guide part 5 near the construction direction. The side baffle 6 has two symmetrical slopes on the side near the guide part 5. The falling rocks that fall on the guide part 5 near the construction direction are guided along both sides of the slope guide support. The side away from the guide part 5 is perpendicular to the receiving part, which can prevent the falling rocks from falling in the construction direction. This design further optimizes the guiding and protective effect of the falling rocks, so that the falling rocks can be guided more smoothly to the ground away from the construction area. At the same time, the side baffle 6 can also prevent the falling rocks from threatening the construction direction.
[0039] Furthermore, such as Figure 2 As shown in Figure 6, a buffer assembly 7 is added between the protective structure 3 and the height adjustment component. The buffer assembly 7 includes a mounting base 9, which is disposed between the protective frame and the height adjustment component 2 and has multiple buffer cavities 8 evenly arranged inside it, and a buffer component 11, which is welded inside the buffer cavity 8 and has a movable column 10 fixedly connected to the protective frame at its top. When the protective structure 3 is compressed by an external force, a downward external force is applied to the movable column 10, causing it to slide downward along the buffer cavity 8 and compress the buffer component 11. The buffer component 11 can be a spring. Under the elastic action of the spring, the external force is buffered, thereby improving the compressive strength of the protective structure 3, extending the service life of the protective structure 3, and further protecting the safety of workers.
[0040] Furthermore, such as Figure 1-7 As shown, the bottom of the stable base 1 is equipped with a driving device. The driving device can be a protective cylinder 12 fixedly installed at the bottom of the stable base 1, a support plate 13 installed inside the protective cylinder 12 via a hydraulic cylinder 15, and traveling wheels 14 fixedly installed on both sides of the protective cylinder 12. When the support needs to be moved, the hydraulic cylinder 15 drives the support plate 13 to retract into the protective cylinder 12, and the traveling wheels 14 contact the ground, applying external force to the support and driving the traveling wheels 14 to rotate, thus realizing the forward movement of the support. The traveling wheels 14 can also be electrically driven. When the support needs to be stopped, the hydraulic cylinder 15 drives the support plate 13 to extend out of the protective cylinder 12, and the support plate 13 contacts the ground, which can prevent the support from shifting during construction, so that the support can move and be positioned flexibly during mining. This design not only improves construction efficiency, but also allows the support to be quickly adjusted in position as needed to adapt to different construction environments and conditions.
