Description

Technical Field

[0001] This utility model relates to the field of underground construction technology, specifically to a tunnel repair work platform. Background Technology

[0002] During long-term mining, the surrounding rock of underground coal mine roadways deforms and is damaged due to the continuous action of mine pressure, which gradually reduces the ventilation cross-section and severely compresses the space for pedestrian passages, making it difficult to meet the basic requirements for safe production.

[0003] To restore the normal service function of the roadway, ensure the smooth operation of the ventilation and transportation systems, and guarantee the safety of underground workers, roadway repair and roof raising operations are usually required. This operation mainly involves manually repairing and raising the roof of the roadway to widen the roadway cross-section.

[0004] However, roof-lifting operations require workers to operate at a high position, and currently, the common practice is to temporarily construct makeshift working platforms using iron ladders and wooden planks. This method presents numerous safety hazards: firstly, the working space is extremely narrow, restricting personnel movement; secondly, the temporary platforms are unstable and prone to swaying; and thirdly, workers lack effective safety protection measures when working at heights. These factors significantly reduce the safety factor of the operation, not only affecting work efficiency but also making it difficult to guarantee the safety of workers, posing a serious threat to coal mine safety production.

[0005] Therefore, we propose a tunnel repair work platform to solve the above problems. Utility Model Content

[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. 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. Example

[0019] like Figure 1-6 As shown in the figure, an embodiment of the present invention provides a roadway repair work platform, including a construction platform device 1. An elevation structure 2 and a material lifting structure 3 are arranged on the outer side of the construction platform device 1, and the elevation structure 2 and the material lifting structure 3 are arranged diagonally.

[0020] The construction platform device 1 includes a load-bearing structure 101, and a protective fence 102 is provided around the top of the load-bearing structure 101. The climbing structure 2 is located at the gap between the load-bearing structure 101 and the protective fence 102. The material lifting structure 3 includes a drive base 301 and a mounting frame 302. A scissor frame 303 is provided on the inner side of the drive base 301. A hydraulic cylinder 307 is hinged to the inner side of the scissor frame 303. A lifting platform 308 is movably connected to the top of the scissor frame 303.

[0021] like Figure 3As shown, in some embodiments, the load-bearing structure 101 includes an installation frame 103, the bottom of which is equipped with four support columns 104, and the bottom of each support column 104 is provided with a contact plate 105. The support columns 104 are connected to the ground of the tunnel through the contact plate 105 and pins.

[0022] Specifically, the contact area between the contact plate 105 and the roadway floor is large, which can effectively disperse the pressure of the construction platform device 1 on the ground, prevent the ground from collapsing due to excessive local pressure, and ensure the stability of the construction platform device 1 in the roadway.

[0023] The pins further enhance the stability of the connection between the support column 104 and the ground, preventing the construction platform device 1 from shaking or shifting during construction, and providing a reliable support foundation for workers working at height.

[0024] like Figure 3 As shown, in some embodiments, two sets of square pedals 106 and rectangular pedals 107 are movably engaged on the inner side of the mounting frame 103. The opening between the square pedals 106 and the rectangular pedals 107 is a mounting notch 108. A discharge window 109 is fixedly installed on the inner side of the mounting notch 108. A closing cover 110 is hinged inside the discharge window 109.

[0025] Specifically, the movable, snap-fit ​​square pedal 106 and rectangular pedal 107 are designed to be highly flexible, allowing for easy adjustment and replacement according to the actual needs of tunnel repair operations. When tunnels in different locations require repair, the pedals can be easily moved to adapt to different work scenarios.

[0026] The material unloading window 109 facilitates the placement of construction materials. During tunnel repair, workers no longer need to frequently move rocks up and down the platform; they can simply place the rocks directly into the required location through the unloading window 109, improving construction efficiency. The sealing cover 110, when not in use, encloses the platform, preventing debris or personnel from accidentally falling and further ensuring operational safety.

[0027] like Figure 4 As shown, in some embodiments, the climbing structure 2 includes a climbing ladder 201, the outer wall of the climbing ladder 201 is connected to the outer edge of the supporting structure 101 by connecting angle iron 202, and a protective fence 203 is welded to the top of the climbing ladder 201.

[0028] Specifically, the use of connecting angle iron 202 makes the connection between the ladder 201 and the load-bearing structure 101 more secure, capable of bearing the weight of the workers working at height, and ensuring that the ladder 201 will not loosen or fall off during use.

[0029] The protective barrier 203 provides additional safety for workers working at heights. When workers are working on the ladder 201, the protective barrier 203 can prevent them from falling from the ladder 201 due to accidents, thus reducing the risk of working at heights.

[0030] like Figure 5 As shown, in some embodiments, a hinge rod 304 is rotatably connected to the inner wall of the drive seat 301, one bottom end of the scissor frame 303 is fixedly sleeved with the surface of the hinge rod 304, and an abutting roller 305 is rotatably connected to the other bottom end of the scissor frame 303. A slide rail 306 is provided on the inner side of the drive seat 301, and the abutting roller 305 overlaps with the top end of the slide rail 306.

[0031] Specifically, the design of the hinge rod 304 allows the scissor frame 303 to rotate flexibly, and under the action of the hydraulic cylinder 307, the scissor frame 303 can achieve lifting and lowering movements.

[0032] The overlapping design of the contact roller 305 and the slide rail 306 ensures the stability of the scissor frame 303 during the lifting process. The contact roller 305 rolls along the slide rail 306, reducing friction and making the lifting process smoother. It also reduces wear on the equipment and extends its service life.

[0033] With the linkage of the hinge rod 304 and the abutment roller 305, the hydraulic cylinder 307 pushes the scissor frame 303 to rise and fall by extending and retracting, thereby driving the lifting platform 308 to achieve smooth rising and falling movements.

[0034] Hydraulic cylinder 307 serves as the power source, ensuring that the material lifting structure 3 has sufficient load-bearing capacity and stability when lifting materials. The easy control and adjustment characteristics of hydraulic cylinder 307 also make the material lifting process more flexible and precise, which can meet the needs of different tunnel repair operation scenarios.

[0035] like Figure 6 As shown, in some embodiments, a connecting guide rail 309 is fixedly installed on the back side of the lifting platform 308. The connecting guide rail 309 is located inside the mounting frame 302 and is slidably connected to the inner wall of the mounting frame 302.

[0036] Specifically, the sliding connection between the connecting guide rail 309 and the mounting frame 302 ensures that the lifting platform 308 moves in a straight line during the lifting process, without any deviation or swaying.

[0037] This allows the material lifting structure 3 to lift materials onto the construction platform device 1 more accurately, improving the precision and efficiency of material lifting.

[0038] Meanwhile, the connecting guide rail 309 also serves to limit the range of motion of the lifting platform 308, preventing the lifting platform 308 from exceeding the safe range during lifting. like Figure 6 As shown, in some embodiments, an angle iron 310 is fixedly installed on the outer wall of the mounting frame 302, and the mounting frame 302 is connected to the outer edge of the bearing structure 101 through the angle iron 310.

[0039] Specifically, the use of the mounting angle iron 310 enhances the stability of the connection between the mounting back frame 302 and the load-bearing structure 101, enabling the material lifting structure 3 to be firmly installed on the construction platform device 1.

[0040] During the material lifting process, the mounting frame 302 needs to bear the weight of the lifting platform 308 and the material. The mounting angle iron 310 can effectively distribute these forces, prevent the mounting frame 302 from deforming or being damaged due to excessive force, and ensure the normal operation of the material lifting structure 3.

[0041] When in use, the operators first securely install the construction platform device 1 on the roadway floor using the contact base plate 105 and pins to ensure that the entire platform will not shake or shift during operation.

[0042] Next, based on the actual needs of tunnel repair operations, the positions of the square pedal 106 and rectangular pedal 107 that are movably connected inside the mounting frame 103 are flexibly adjusted and replaced to adapt to different operating scenarios.

[0043] When construction materials need to be placed, workers can open the cover 110 of the material discharge window 109 and place materials such as rocks directly into the required location through the material discharge window 109, without having to frequently move them up and down the platform, thus improving construction efficiency.

[0044] When it is necessary to lift the materials required for construction to the construction platform device 1, the operator starts the hydraulic cylinder 307 of the material lifting structure 3 through the power supply built into the tunnel, and pushes the scissor frame 303 to lift and lower by telescopic movement.

[0045] The scissor frame 303 achieves smooth lifting and lowering motion through the linkage of the hinge rod 304 and the abutment roller 305, thereby driving the lifting platform 308 to rise.

[0046] The connecting guide rail 309 on the back side of the lifting platform 308 is slidably connected to the inner wall of the mounting frame 302, ensuring the linear movement of the lifting platform 308 during the lifting process and improving the accuracy and efficiency of material lifting. After the lifting platform 308 rises to the designated height, the operator can move the material from the lifting platform 308 to the construction platform device 1 for operation.

[0047] In summary, the construction platform device 1, with its load-bearing structure 101, can stably support personnel climbing at heights. Combined with the protective fence 102, it can effectively protect personnel climbing at heights. At the same time, the setting of the material unloading window 109 and the sealing cover 110 not only facilitates the delivery of materials during tunnel repair, but also maintains the platform's closure when materials are not needed, preventing debris or personnel from accidentally falling, thus further improving operational safety.

[0048] Through the material lifting structure 3, the combination design of drive seat 301, scissor frame 303 and hydraulic cylinder 307 is adopted to realize the smooth lifting of the lifting platform 308. It can conveniently lift the materials required for construction to the construction platform device 1, reduce the tediousness and danger of manual handling, further improve the convenience and efficiency of construction, and improve the work efficiency.

[0049] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
