Description

Technical Field

[0001] This utility model relates to the field of coal mine roadway support technology, and more specifically, to a coal mine roadway support operation platform. Background Technology

[0002] The stability control of surrounding rock in coal mine roadways is crucial for safe production, especially in deep mines and roadways with complex geological conditions. Traditionally, U-shaped support combined with deep and shallow hole grouting and anchor cable (rod) support is widely used to control the deformation of surrounding rock in roadways, addressing issues such as fractured, weak, highly hydrophilic rock and the development of fissure water. These technologies can effectively control surrounding rock deformation to a certain extent, especially in the initial deformation control of the surrounding rock in roadways, demonstrating good results.

[0003] However, in special areas such as soft rock tunnels and fault zones, the deformation characteristics of the surrounding rock exhibit long-term and persistent behavior, which places higher demands on the timeliness and effectiveness of the support system. Currently, anchor cable (rod) support operations mainly rely on scaffolding as operating platforms. This method is not only inefficient but also occupies tunnel space during support operations, seriously affecting transportation and production progress. Especially in deep shaft tunnels, where the tunnel length is long and the support operation area is wide, setting up anchor cable (rod) support operating platforms in every U-shaped shed would greatly increase the construction cost of the support operation. At the same time, fixed operating platforms occupy a large amount of upper space, causing inconvenience to workers' movement and vehicle passage, seriously affecting the normal operation and production efficiency of the tunnel.

[0004] In existing technology, a patent has disclosed an operating platform for anchor cable and bolt support in coal mine roadways (Publication No.: CN218454755U). This platform includes two inverted U-shaped steel frames connected by reaction steel plates. A hoist and cable-suspended platform frame are located at the top. The platform frame is equipped with a limiting mechanism that can extend into limiting grooves and sliding channels for support operations in fixed positions. While this design can solve the problems of platform fixation and swaying to some extent, its limitations in practical applications remain significant, especially in long roadways. The fixed nature of the operating platform restricts its flexibility at different support points, increasing the complexity and cost of support operations. Utility Model Content

[0005] The main purpose of this utility model is to provide a coal mine roadway support operation platform to solve the technical problem that the fixed setting of the operation platform in the prior art makes the support operation more complicated.

[0006] To achieve the above objectives, according to one aspect of the present invention, a coal mine roadway support operation platform is provided, comprising:

[0007] The support body includes at least two support frames and a sliding component, with adjacent support frames connected by connectors; the support frames are provided with interconnecting sliding grooves and connecting sliding grooves, the connecting sliding grooves extending vertically and the connecting sliding grooves extending horizontally; the sliding component includes a sliding guide rail and a connecting slider, the sliding guide rail is installed on the inner side of the support frame, and the connecting slider is slidably connected to the sliding guide rail;

[0008] The support body includes a support assembly and a positioning assembly. The support assembly includes a support rod, a support platform, a cable, and a lifting device. The support rod is connected to a sliding guide rail via a connecting slider to move along the sliding guide rail. The support platform is connected to the lifting device via a cable, so that operating the lifting device can retract the cable, causing the support platform to rise relative to the support frame. The positioning assembly includes a positioning slider, which is disposed on the support platform. The positioning slider is slidably connected to both the connecting groove and the connecting groove of the support frame. After the lifting device lifts the support platform to a predetermined position, the positioning slider moves from the connecting groove to the connecting groove. When the support rod is moved along the sliding guide rail, the positioning slider slides along the connecting groove, causing the support platform to move along the extension direction of the sliding guide rail.

[0009] Furthermore, in the coal mine roadway support operation platform, one end of the sliding guide rail is provided with a connection interface, and the other end is provided with a connection joint. There are multiple support bodies. The connection joint of the sliding guide rail of one support body is inserted into the connection interface of another support body so that the two adjacent support bodies can be spliced ​​together so that the support component can be moved from one support body to another support body.

[0010] Furthermore, the coal mine roadway support operation platform, the support body also includes a limiting slider, and the support frame is provided with an auxiliary slide groove. The limiting slider is slidably set in the auxiliary slide groove so that the limiting slider can be moved to the connecting slide groove to limit the positioning slider, or the limiting slider can be moved away from the connecting slide groove so that the positioning slider can be moved into the connecting slide groove.

[0011] Furthermore, in the coal mine roadway support operation platform, the limiting slider is equipped with an operating handle, and the support frame is equipped with a positioning groove. The position of the operating handle is adjustable so that it can be inserted into or removed from the positioning groove. There are multiple positioning grooves, which are arranged at intervals along the vertical direction so that the operating handle can be selectively inserted into one positioning groove.

[0012] Furthermore, in the coal mine roadway support operation platform, the operating handle is rotatably mounted on the limiting slider.

[0013] Furthermore, the support components of the coal mine roadway support operation platform also include pull rings, which are located at the bottom of the support rods, so that the support rods can be moved along the sliding guide rails by operating the pull rings.

[0014] Furthermore, the support components of the coal mine roadway support operation platform also include a protective roof and a support net, with the support net located inside the protective roof and the protective roof and support net located above the support platform.

[0015] Furthermore, the positioning component of the coal mine roadway support operation platform also includes a fixing device, which is mounted on the connecting slider. At least a portion of the fixing device is adjustable to clamp or release the sliding guide rail.

[0016] Furthermore, the coal mine roadway support operation platform includes a fixing device comprising a fixing block, a movable chute, two sliding clamps, and a bidirectional screw rod. The fixing block is disposed on the connecting slider, and the two sliding clamps are movably disposed within the movable chute. The two sliding clamps are connected by the bidirectional screw rod, so that by rotating the bidirectional screw rod, the two sliding clamps can be moved closer or further apart to fix or release the sliding guide rail.

[0017] Furthermore, the lifting device for the coal mine roadway support operation platform is an electric hoist or a manual hoist.

[0018] The technical solution of this utility model comprises a support body consisting of at least two support frames, which are interconnected by connectors to form a stable support structure. Each support frame is provided with interconnected connecting grooves and connecting grooves. The connecting grooves extend vertically for positioning and supporting the sliding components; the connecting grooves extend horizontally to enable horizontal movement of the support platform, thereby facilitating support operations at different locations in the roadway. The sliding components include sliding guide rails and connecting sliders. The sliding guide rails are installed inside the support frames, while the connecting sliders are slidably connected to the sliding guide rails, allowing the support components to move up and down along the sliding guide rails. The support components of the support body include support rods, a support platform, cables, and a lifting device. The support rods are connected to the sliding guide rails via connecting sliders, allowing them to move along the sliding guide rails. The support platform is connected to the lifting device via cables. The lifting device can be an electric hoist or a manual hoist. By operating the lifting device, the cables are contracted or relaxed, thereby controlling the rise or fall of the support platform relative to the support frames. The positioning sliders of the positioning components are installed on the support platform and are slidably connected to the connecting grooves and connecting grooves. In this way, after the lifting device raises the support platform to the predetermined position, the positioning slider can move from the connecting slide groove to the connecting slide groove, restricting the vertical movement of the support platform while allowing it to slide horizontally. By moving the support rod along the sliding guide rail, the positioning slider slides horizontally along the connecting slide groove, enabling the support platform to move along the extension direction of the sliding guide rail to reach the new working position. The mobility of the support platform ensures that workers can work in multiple locations in the roadway without frequently changing work platforms. Through the movable design of the support platform, it can move flexibly along the sliding guide rail and connecting slide groove, reducing the need for setting up multiple fixed platforms in the roadway and improving mobility.

Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 6As shown, an embodiment of this utility model provides a coal mine roadway support operation platform, comprising: a support body, including at least two support frames 1 and a sliding assembly, with adjacent support frames 1 connected by connectors 2; the support frames 1 are provided with interconnected connecting grooves 10 and connecting grooves 11, the connecting grooves 10 extending vertically and the connecting grooves 11 extending horizontally; the sliding assembly includes a sliding guide rail 3 and a connecting slider 4, the sliding guide rail 3 being installed on the inner side of the support frame 1, and the connecting slider 4 being slidably connected to the sliding guide rail 3; a support body, including a support assembly and a positioning assembly, the support assembly including a support rod 5, a support platform 9, a cable 8, and a lifting device 7, the support rod 5 being connected to the connecting slider. 4 is connected to the sliding guide rail 3 to move along the sliding guide rail 3; the support platform 9 is connected to the lifting device 7 via the cable 8 so that the cable 8 can be retracted by operating the lifting device 7, so that the support platform 9 rises relative to the support frame 1; the positioning component includes a positioning slider 12, which is disposed on the support platform 9. The positioning slider 12 is slidably connected to the connecting groove 10 and the connecting groove 11 of the support frame 1, so that after the lifting device 7 lifts the support platform 9 to a predetermined position, the positioning slider 12 moves from the connecting groove 10 to the connecting groove 11, and when the operating support rod 5 moves along the sliding guide rail 3, the positioning slider 12 slides along the connecting groove 11, so that the support platform 9 moves along the extension direction of the sliding guide rail 3.

[0030] By applying the technical solution of this utility model and adopting the coal mine roadway support operation platform provided by the embodiment of this utility model, the mobility of the support platform 9 ensures that workers can work in multiple positions in the roadway without frequently changing the work platform. Through the movable design of the support platform 9, it can move flexibly along the sliding guide rail 3 and the connecting slide 11, reducing the need to set up multiple fixed platforms in the roadway and improving the mobility.

[0031] In the above embodiment, the support body consists of at least two support frames 1, which are interconnected by connectors 2 to form a stable support structure. Each support frame 1 is provided with interconnected connecting grooves 10 and connecting grooves 11, wherein the connecting grooves 10 extend vertically for positioning and supporting the sliding assembly; the connecting grooves 11 extend horizontally for enabling the horizontal movement of the support platform 9, thereby allowing support operations to be performed at different locations in the roadway. The sliding assembly includes a sliding guide rail 3 and a connecting slider 4. The sliding guide rail 3 is installed on the inner side of the support frame 1, and the connecting slider 4 is slidably connected to the sliding guide rail 3, allowing the support assembly to move up and down along the sliding guide rail 3. The support assembly of the support body includes a support rod 5, a support platform 9, a cable 8, and a lifting device 7. The support rod 5 is connected to the sliding guide rail 3 via the connecting slider 4, allowing it to move along the sliding guide rail 3. Each of the two support rods 5 has a support platform 6 at its top center. Lifting devices 7 are located on opposite sides of the two support platforms 6. The support platform 9 is connected to the lifting device 7 via a cable 8. The lifting device 7 can be an electric hoist or a manual hoist. By operating the lifting device 7, the cable 8 is contracted or relaxed, thereby controlling the rise or fall of the support platform 9 relative to the support frame 1. The positioning slider 12 of the positioning assembly is mounted on the support platform 9 and can slide in conjunction with the connecting groove 10 and the connecting groove 11. Thus, when the lifting device 7 lifts the support platform 9 to a predetermined position, the positioning slider 12 can move from the connecting groove 10 into the connecting groove 11, restricting the vertical movement of the support platform 9 while allowing it to slide horizontally. By moving the support rods 5 along the sliding guide rail 3, the positioning slider 12 slides horizontally along the connecting groove 11, enabling the support platform 9 to move along the extension direction of the sliding guide rail 3 to reach a new working position.

[0032] Specifically, in the coal mine roadway support operating platform, a connecting interface 13 is provided at one end of the sliding guide rail 3, and a connecting joint 14 is provided at the other end. Multiple support bodies are used. The connecting joint 14 of the sliding guide rail 3 of one support body is inserted into the connecting interface 13 of another support body, allowing adjacent support bodies to be spliced ​​together, enabling the support components to move from one support body to another. To adapt to the variable length of the roadway, the coal mine roadway support operating platform is designed with the connecting interface 13 and connecting joint 14 of the sliding guide rail 3. The sliding guide rail 3 serves as the track for the movement of the support components, with a connecting interface 13 at one end and a connecting joint 14 at the other. This design allows the platform to be assembled from multiple independent support bodies. Each support body is equipped with a sliding guide rail 3, a connecting groove 10, a connecting groove 11, and the necessary connecting parts 2. When it is necessary to expand the platform's application range to cover longer roadway sections, the support bodies can be spliced ​​together. The assembly process is simple and convenient: Align the sliding guide rail 3 connecting joint 14 of one support body with the sliding guide rail 3 connecting interface 13 of another support body, then insert and fix it to form a continuous sliding guide rail 3. This allows the support components to move smoothly from one support body to another, enabling continuous operation along the roadway. Each support body is securely connected by connectors 2, ensuring the overall stability and safety of the platform. The connectors 2 are designed with the special environment of coal mine roadways in mind, using high-strength materials capable of withstanding the loads during platform movement and support operations, preventing platform displacement or structural damage.

[0033] Specifically, the coal mine roadway support operation platform includes a limiting slider 16 in the support body. An auxiliary slide groove 15 is provided on the support frame 1. The limiting slider 16 is slidably disposed within the auxiliary slide groove 15, allowing it to be moved to the connecting slide groove 11 to limit the positioning slider 12, or removed from the connecting slide groove 11 to allow the positioning slider 12 to move into the connecting slide groove 11. In this coal mine roadway support operation platform, the structure of the support body is further optimized by introducing the limiting slider 16 and the auxiliary slide groove 15 mechanism to enhance the platform's positioning stability and operational flexibility. The support frame 1 is provided with an auxiliary slide groove 15, which communicates with the connecting slide groove 11 provided on the support frame 1. The limiting slider 16 is designed to be slidably installed within the auxiliary slide groove 15, and its position within the auxiliary slide groove 15 is controlled by an operating handle 17.

[0034] In the above embodiments, when it is necessary to fix the support platform 9 in a certain working position, the operator can move the limiting slider 16 to the connecting groove 11 by operating the handle 17. The protruding part of the limiting slider 16 will contact the positioning slider 12, thereby preventing the positioning slider 12 from moving horizontally along the connecting groove 11, thus ensuring the stability of the support platform 9 in the vertical direction and preventing it from swaying or accidentally sliding down during support operations. When it is necessary to move the support platform 9 to a new working position, the operator only needs to remove the operating handle 17 from the positioning groove 19 in the fixed position, and then slide the limiting slider 16 upward along the auxiliary groove 15 to disengage it from contact with the positioning slider 12. The positioning slider 12 can then move freely along the connecting groove 11 into the connecting groove 11. Then, the lifting device 7 is used to raise or lower the support platform 9. By moving the support rod 5 along the sliding guide rail 3, the positioning slider 12 slides horizontally along the connecting groove 11, realizing the movement of the support platform 9 along the extension direction of the sliding guide rail 3 to the new working position. To further improve the ease of operation, the operating handle 17 is rotatably mounted on the limiting slider 16. When it is necessary to fix the limiting slider 16, the operating handle 17 can be rotated and inserted into the positioning groove 19 on the support frame 1. The positioning groove 19 is arranged at intervals along the vertical direction, so that the operating handle 17 can be fixed at different height positions to adapt to different operating needs.

[0035] Specifically, in the coal mine roadway support operating platform, the limiting slider 16 is equipped with an operating handle 17, and the support frame 1 is equipped with a positioning groove 19. The position of the operating handle 17 is adjustable to insert into or remove from the positioning groove 19. Multiple positioning grooves 19 are arranged at intervals along the vertical direction, allowing the operating handle 17 to be selectively inserted into one groove. This coal mine roadway support operating platform of the present invention features an operating handle 17 on the limiting slider 16 of its positioning component. This design makes the positioning and fixing of the platform more convenient and efficient. The position of the operating handle 17 is adjustable, allowing it to be inserted into or removed from the positioning groove 19 on the support frame 1. The positioning grooves 19 are arranged along the vertical support frame 1 at intervals in the vertical direction, forming multi-level positioning points. This allows the operating handle 17 to be fixed at different heights, thereby ensuring that the support platform 9 can be stably fixed at different working heights.

[0036] In use, the operator can use the operating handle 17 to move the limiting slider 16 along the auxiliary slide groove 15 to the connecting slide groove 11, thereby moving the positioning slider 12 from the connecting slide groove 10 into the connecting slide groove 11. At this time, the operating handle 17 can be inserted into the positioning groove 19 to fix the limiting slider 16, thereby fixing the positioning slider 12 and preventing the support platform 9 from accidentally sliding in the horizontal direction. When it is necessary to adjust the height of the support platform 9, the operator only needs to remove the operating handle 17 from the positioning groove 19, adjust the support platform 9 to the new height using the lifting device 7, and then insert the operating handle 17 into the new positioning groove 19 to complete the repositioning.

[0037] Specifically, in the coal mine roadway support operating platform, the operating handle 17 is rotatably mounted on the limiting slider 16. This rotatable mounting of the operating handle 17 on the limiting slider 16 is designed to control the movement of the positioning slider 12 between the connecting groove 11 and the connecting groove 10, thereby achieving precise positioning and horizontal movement of the support platform 9. Specifically, the operating handle 17 is movably connected to the limiting slider 16 via a connecting shaft 18, allowing the operating handle 17 to rotate around the shaft, facilitating grip and use by the operator at different angles. Each support frame 1 is provided with an auxiliary groove 15, within which the limiting slider 16 is slidably mounted. When the support platform 9 needs to be fixed in a certain position for operation, the operator slides the limiting slider 16 to the connecting groove 11. At this time, the positioning slider 12 is located in the connecting groove 11. By rotating the operating handle 17, it is inserted into the positioning groove 19. The limiting slider 16 is thus fixed at the top connection between the connecting groove 11 and the connecting groove 10, effectively preventing the positioning slider 12 from sliding out of the connecting groove 10, thereby stabilizing the position of the support platform 9. When it is necessary to move the support platform 9, the operation is reversed. First, the operating handle 17 is removed from the positioning groove 19, and then the limiting slider 16 is slid away from the connecting groove 11, so that the positioning slider 12 can move freely between the connecting groove 10 and the connecting groove 11, thereby realizing the horizontal displacement of the support platform 9.

[0038] Specifically, the support components of the coal mine roadway support operating platform also include a pull ring 20, which is located at the bottom of the support rod 5. By operating the pull ring 20, the support rod 5 can be moved along the sliding guide rail 3. The pull ring 20 is specially designed to facilitate operator control of the movement of the support rod 5. This pull ring 20 is installed at the bottom of the support rod 5, and the movement of the support rod 5 along the sliding guide rail 3 can be achieved through simple manual operation. Specifically, the operator only needs to hold the pull ring 20 and pull in the desired direction, and the support rod 5 will slide along the sliding guide rail 3, thereby easily changing the position of the support platform 9. To ensure safe and convenient operation, the material selection and design of the pull ring 20 have been carefully considered. It is typically made of a high-strength, lightweight alloy material with a non-slip surface to provide a good grip. The pull ring 20 is designed to be low enough that even in situations where roadway space is limited, the operator can easily access and use it.

[0039] Specifically, the coal mine roadway support operating platform includes a protective roof 21 and a support net 22. The support net 22 is located inside the protective roof 21, and both the protective roof 21 and the support net 22 are positioned above the support platform 9. The protective roof 21 is designed with a V-shaped structure, with an open top to facilitate support operations, while the bottom of the V-shape concentrates falling debris into a smaller area, preventing debris from scattering and affecting worker operations or creating safety hazards. The protective roof 21 is connected to the connecting slider 4 via support rods 5, allowing it to rise and fall with the support platform 9, ensuring a safe working environment for workers at different operating heights. The support net 22 is located inside the protective roof 21, close to its underside. The support net 22 is made of high-strength, high-density material, effectively intercepting larger debris and dust, further enhancing the safety protection effect of the protective roof 21 and providing more comprehensive safety protection for workers. The presence of the support net 22 also enhances the structural stability of the protective roof 21, especially when performing support operations at higher positions, effectively preventing the protective roof 21 from deforming due to external impacts. To ensure the structural strength and stability of the entire platform, the materials and structural design of the protective top 21 have been carefully considered, ensuring sufficient strength to withstand potential impacts while maintaining lightweight design to avoid increasing the burden on the platform. At the same time, the connection between the protective top 21 and the supporting platform 9 is stable and reliable, capable of withstanding dynamic loads from repeated lifting and lowering.

[0040] Specifically, the positioning component of the coal mine roadway support operating platform also includes a fixing device 23. The fixing device 23 is mounted on the connecting slider 4, and at least a portion of its position is adjustable to clamp or release the sliding guide rail 3. The design of the fixing device 23 allows for adjustment of the position of some or all of its components to clamp the sliding guide rail 3 when needed, fixing the support platform 9, or to release the sliding guide rail 3 when moving the support platform 9, allowing the support platform 9 to slide freely along the guide rail. The fixing device 23 mainly includes a fixing block 24, a movable slide groove 25, two sliding clamping blocks 26, and a bidirectional screw 27. The fixing block 24 is fixed to the connecting slider 4, and the movable slide groove 25 is located within the fixing block 24. The two sliding clamping blocks 26 can slide within the movable slide groove 25 along the groove direction. The bidirectional screw 27 passes through these two sliding clamping blocks 26, and by rotating the bidirectional screw 27, the two sliding clamping blocks 26 can be driven to move towards the center or to the sides. When the fixing device 23 is in the clamping state, the two sliding clamps 26 are tightly attached to the sliding guide rail 3, forming a strong frictional connection, effectively preventing accidental movement of the support platform 9. When the fixing device 23 is in the released state, the two sliding clamps 26 separate from the sliding guide rail 3, allowing the support platform 9 to slide freely along the sliding guide rail 3, facilitating the movement and positioning of the platform. To improve the clamping effect of the fixing device 23, anti-slip teeth 28 are installed on the opposite sides of the sliding clamps 26, increasing the friction between the clamps and the sliding guide rail 3, ensuring the stability and reliability of platform clamping in complex tunnel environments.

[0041] Specifically, the fixing device 23 of the coal mine roadway support operating platform includes a fixing block 24, a movable slide 25, two sliding clamps 26, and a bidirectional screw 27. The fixing block 24 is mounted on the connecting slider 4. The two sliding clamps 26 are movably mounted within the movable slide 25 and are connected by the bidirectional screw 27. Rotating the bidirectional screw 27 allows the two sliding clamps 26 to move closer or further apart, thus fixing or releasing the sliding guide rail 3. The fixing device 23 is a key component ensuring the stability of the platform during movement and operation. The fixing device 23 mainly includes the fixing block 24, the movable slide 25, the two sliding clamps 26, and the bidirectional screw 27. The fixing block 24 is mounted on the connecting slider 4, serving as the base of the entire fixing device 23, and is used to support the movable slide 25 and the sliding clamps 26. The movable slide 25 is a structure with an internal sliding path, open at both ends, allowing the two sliding clamps 26 to slide freely within it. The sliding clamp 26 is designed to contact the sliding guide rail 3, typically in a clamping shape, to facilitate clamping or releasing the sliding guide rail 3. Two sliding clamps 26 are connected by a bidirectional lead screw 27. When the bidirectional lead screw 27 rotates, its special thread design allows the two sliding clamps 26 to move closer or further apart, thus fixing or releasing the sliding guide rail 3. When the operator needs to fix the platform for support work, rotating the bidirectional lead screw 27 moves the two sliding clamps 26 towards the center, clamping the sliding guide rail 3 and ensuring the stability of the support platform 9 during operation. When the platform needs to be moved to the next working position, rotating the bidirectional lead screw 27 in the opposite direction moves the two sliding clamps 26 away from each other, releasing the clamp on the sliding guide rail 3. The support platform 9 can then move to the new position along the sliding guide rail 3 and the connecting groove 11 through the cooperation of the lifting device 7 and the support rod 5.

[0042] Specifically, the lifting device 7 of the coal mine roadway support operating platform can be either an electric hoist or a manual hoist. The electric hoist, as a powered lifting device, uses electricity to raise and lower the support platform 9. Electric hoists are typically installed on top of the support frame 1, and their power source can be a fixed electrical system or a portable battery pack to adapt to different working conditions within the roadway. Electric hoists are equipped with necessary control devices, such as buttons or remote controls, allowing operators to easily control the raising and lowering of the support platform 9 and ensure precise positioning at the required height. Furthermore, electric hoists are designed with safety protection mechanisms, such as overload protection and an emergency stop button, to deal with emergencies and ensure operator safety. The manual hoist is a non-powered lifting device 7 that raises and lowers the support platform 9 through manual operation. Manual hoists typically have chains or ropes, which operators pull to raise or lower the support platform 9. The design of manual hoists takes into account the complex environment of coal mine roadways, especially in situations where power supply is unstable or limited, providing a reliable lifting solution. Manual hoists are typically small, lightweight, easy to install and maintain, and suitable for use in confined tunnels.

[0043] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0044] Enhanced flexibility and adaptability: Through the design of sliding guide rail 3, connecting slide 10 and connecting slide 11, the support platform 9 can move freely in the vertical and horizontal directions, achieving full-section interference-free support, which greatly improves the flexibility and adaptability of the operating platform and can effectively cope with the complex terrain and support requirements of coal mine roadways.

[0045] Rapid positioning and movement: The sliding connection between the positioning slider 12 and the connecting slide 10 and the connecting slide 11, as well as the cooperation between the limiting slider 16 and the auxiliary slide 15, enable the support platform 9 to be quickly positioned in the construction position and stably supported. At the same time, it also allows the platform to move easily between different support frames 1, saving positioning time and improving work efficiency.

[0046] Cost-effectiveness and space optimization: The design of the connection interface 13 and connection joint 14 of the sliding guide rail 3 allows multiple support bodies to be spliced ​​together, reducing the duplication of the support platform 9 and saving material costs.
