Description

Technical Field

[0001] This utility model relates to the field of underground coal mine roadway technology, specifically to a push-type maintenance platform for underground roadways. Background Technology

[0002] To meet the ever-increasing demand for underground material and equipment transportation, the size and weight of underground transportation equipment have gradually increased. Roadway space has become a major constraint on the transportation of equipment and materials. Currently, auxiliary transportation equipment such as monorail cranes in coal mines need to be cleaned, inspected, and maintained in roadways or chambers.

[0003] The aforementioned cleaning and maintenance processes involve working at heights, as well as disassembling and replacing parts. The confined working space poses a risk of personnel falling and objects slipping. If a fixed elevated platform is set up, it will affect the normal transportation of the monorail and the movement of personnel. If a mobile elevated platform is used, the stability of the platform cannot be guaranteed, and manual handling is extremely inconvenient. Solving these problems is urgent. Utility Model Content

[0004] To address the shortcomings of existing technologies, a sliding maintenance platform for underground roadways is proposed, which solves the problems of mobile aerial platforms in the aforementioned technologies, which cannot better guarantee the stability of the aerial platform and are extremely inconvenient for manual handling.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A sliding maintenance platform for underground roadways includes a mobile platform located above a support platform and slidably disposed relative to the support platform. A limit component is provided between the mobile platform and the support platform to fix the position between the mobile platform and the support platform, thereby facilitating maintenance work by personnel on the mobile platform.

[0007] Furthermore, the support platform is fixedly installed in the tunnel, and the support platform includes a horizontally arranged support frame. The mobile platform is arranged parallel to the support frame and slidably connected above the support frame.

[0008] Furthermore, the mobile platform at least partially overlaps with the support frame, and a pushing component is provided at the end of the mobile platform away from the support frame. The mobile platform is slidably connected to the tunnel through the pushing component.

[0009] Furthermore, two sets of pulleys are symmetrically arranged below the mobile platform. The pulleys are rotatably connected to the slide rails, which are arranged along the sliding direction of the mobile platform and fixedly installed on the support frame.

[0010] Furthermore, the limiting component includes a limiting pin, a limiting ring fixedly connected to the mobile platform, and a limiting plate fixedly installed on the support frame. The limiting pin passes through the limiting ring and is inserted into the limiting plate to limit the movement of the mobile platform.

[0011] Furthermore, the limiting plate is provided with limiting holes, and a plurality of limiting holes are provided, which are arranged along the extension direction of the slide rail and are equidistantly distributed.

[0012] Furthermore, the pushing assembly includes a pushing wheel and a support frame. Two support frames are provided, and the two support frames are symmetrically installed below the moving platform. The pushing wheel is rotatably connected to the bottom end of the support frame.

[0013] Furthermore, each end of the slide rail is provided with a stop block. When the pulley rolls to the end of the slide rail, it abuts against the stop block, thereby preventing the pulley from disengaging from the slide rail.

[0014] Furthermore, a reinforcing rib is provided between the mobile platform and the support frame, and the reinforcing rib is inclined. A ladder is provided between the two support frames to facilitate workers climbing onto the mobile platform.

[0015] Furthermore, a grounding frame is provided below the support frame, and the bottom end of the grounding frame is anchored to the roadway through a fixing plate. A reinforcing frame is provided between the support frame and the grounding frame.

[0016] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0017] This application solves the problem of fixed aerial platforms occupying a large space and being unable to move by setting up a mobile platform and a support platform to work together. The support platform provides support for the mobile platform. The mobile platform can be pushed or pulled to the required position and fixed or pushed back to its original position. At the same time, the device has the advantages of high stability and convenient access to heights, eliminating the risk of falls from heights during underground roadway operations, ensuring safety and improving work efficiency.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to 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.

[0024] like Figures 1 to 3 As shown, a sliding maintenance platform for underground roadways includes a mobile platform 1, which is located above a support platform 2 and is slidably arranged relative to the support platform 2. A limit component is provided between the mobile platform 1 and the support platform 2 to fix the position between the mobile platform 1 and the support platform 2, thereby facilitating maintenance work by workers on the mobile platform 1.

[0025] By setting up a mobile platform 1 in conjunction with a support platform 2, with the support platform 2 providing support for the mobile platform 1, and by pushing or pulling the mobile platform 1 to the required position and fixing it or pushing it back to its original position, the disadvantages of fixed climbing platforms being large in space and unable to move are solved. At the same time, this device has the advantages of high stability and convenient climbing, eliminating the risks and hidden dangers of falling from heights during underground roadway climbing operations, ensuring safety and improving work efficiency.

[0026] Specifically, during use, the mobile platform 1 is manually pushed, and under the action of the pushing force, the mobile platform 1 slides to the appropriate position. The limiting component is used to lock the mobile platform 1 to the support platform 2 to prevent the mobile platform 1 from sliding back and forth. After use, the lock between the mobile platform 1 and the support platform 2 is released, and the mobile platform 1 is manually pushed back to its original position to achieve storage.

[0027] In this embodiment of the underground roadway moving maintenance platform, the support platform 2 is fixedly installed in the roadway. The support platform 2 includes a horizontally arranged support frame 3. The moving platform 1 is arranged parallel to the support frame 3 and is slidably connected above the support frame 3.

[0028] Specifically, a grounding frame is installed below the support frame 3. The bottom end of the grounding frame is anchored to the roadway via a fixing plate, and a reinforcing frame is installed between the support frame 3 and the grounding frame. With the above structure, the support platform 2 is fixed to the roadway side by anchor bolts to ensure stable support for the mobile platform 1.

[0029] Preferably, the support frame 3 and the grounding frame form a fixed frame, and the reinforcing frame is inclined to form a triangular structure. Four fixing plates are set, and the fixed frame can be effectively fixed to the roadway side and roadway floor by anchoring methods such as anchor bolts. Multiple anchoring points, together with the triangular fixing of the frame, can ensure that the support frame 3 can be firmly fixed to the roadway side and roadway floor, reducing the possibility of accidents such as shaking, displacement or even tipping of the maintenance platform that may be caused by frame displacement or deformation during operation.

[0030] In the underground roadway moving maintenance platform of this embodiment, the moving platform 1 overlaps at least partially with the support frame 3, and a moving component is provided at the end of the moving platform 1 away from the support frame 3. The moving platform 1 is slidably connected to the roadway through the moving component.

[0031] With the above configuration, the mobile platform 1 maintains partial contact with the support frame 3, thereby obtaining effective support from the support frame 3. The other side is supported by contacting the tunnel floor through the pushing component, and can slide. The mobile platform 1 improves stability by supporting and sliding at two points.

[0032] In this embodiment of the underground roadway moving maintenance platform, two sets of pulleys 4 are symmetrically arranged below the moving platform 1. The pulleys 4 are rotatably connected in the slide rail 5. The slide rail 5 is arranged along the sliding direction of the moving platform 1 and is fixedly installed on the support frame 3.

[0033] Specifically, a sliding rail 5 is installed on the support frame 3. The moving platform 1 is connected to the support frame 3 via pulleys 4 and the sliding rail 5. Two sets of pulleys 4 provide rolling friction for the movement of the moving platform 1, making manual movement of the maintenance platform more convenient and labor-saving. The position of the maintenance platform can be adjusted at will according to needs, with less requirement for the width of the tunnel and a wide range of adaptability. At the same time, the sliding rails 5 on both sides guide the pulleys 4 and the moving platform 1, ensuring that the moving platform 1 moves in a straight line, avoiding its deviation, and improving the stability of the movement.

[0034] Preferably, the slide rail 5 is provided with a stop at each end. When the pulley 4 rolls to the end of the slide rail 5, it abuts against the stop, thereby preventing the pulley 4 from disengaging from the slide rail 5.

[0035] The track of the push pulley 4 is within the push rail 5. The stop block provides end protection at both ends of the push rail 5, effectively preventing the push pulley 4 from deviating from its track or from detaching from the end of the rail 5 during operation, thus preventing the platform from tipping over. This effectively reduces the manual effort required to push the platform while ensuring the stability of the platform.

[0036] In this embodiment, the pushing assembly includes a pushing wheel 9 and a support frame 10. There are two support frames 10, which are symmetrically installed below the mobile platform 1. The pushing wheel 9 is rotatably connected to the bottom end of the support frame 10.

[0037] The height of the mobile platform 1 is effectively determined based on the height of the support platform 2, and the height of the support frame 10 is also determined. The push-type maintenance platform uses two sets of push wheels 9 to support one side of the mobile platform 1. With multiple support points and greater support force, the maintenance platform has high stability. The width of the mobile platform 1 is determined according to the actual required width. The mobile platform 1 with the pulleys 4 installed is placed on top of the support frame 3, ensuring that the pulleys 4 can be placed in the slide rail 5.

[0038] Preferably, a reinforcing rib is provided between the mobile platform 1 and the support frame 10. The reinforcing rib is inclined and uses a triangular structure to stabilize the maintenance platform frame, which improves safety performance. A ladder is provided between the two support frames 10 to facilitate workers to climb onto the mobile platform 1.

[0039] In the underground roadway moving maintenance platform of this embodiment, the limiting component includes a limiting pin 6, a limiting ring 7 fixedly connected to the moving platform 1, and a limiting plate fixedly installed on the support frame 3. The limiting pin 6 passes through the limiting ring 7 and is inserted into the limiting plate to limit the movement of the moving platform 1.

[0040] A fixing pin is installed on the maintenance platform. When the maintenance platform reaches the required position, the position of the moving platform 1 can be fixed by the limiting pin 6, effectively preventing the maintenance platform from shifting during operation. Preferably, two sets of limiting pins 6, limiting rings 7, and limiting plates are symmetrically arranged about the maintenance platform, limiting the moving platform 1 from both sides, improving the fixing effect and enhancing the stability of the platform.

[0041] In the underground roadway moving maintenance platform of this embodiment, the limiting plate is provided with limiting holes 8, and there are several limiting holes 8. The several limiting holes 8 are arranged along the extension direction of the slide rail 5 and are evenly distributed.

[0042] The limit hole 8 is set to facilitate the bottom end of the limit pin 6 to be inserted into the limit plate. Multiple limit holes 8 increase the adjustable position range of the mobile platform 1, so that the length of the mobile platform 1 extending out of the support frame 3 can be adjusted, and the position of the maintenance platform can be more in line with the actual working needs.

[0043] In this embodiment of the underground roadway moving maintenance platform, a maintenance platform step is placed on top of the moving platform 1 to support personnel maintenance work. A protective fence is set on the outer side of the upper part of the moving platform 1 to protect the safety of personnel working at heights and effectively reduce the occurrence of falls from heights. In conjunction with the climbing ladder installed on one side, it is convenient for personnel to climb to heights.
