After connection, the two fixed guardrails and one movable guardrail can form an arc-shaped guardrail as a whole to fit the upper edge of the semicircular notch. In this way, when people pass through, the movable guardrail can be opened to provide support and protection for the people, while expanding the space for passing; when no people pass through, the movable guardrail is closed and connected and locked with the fixed guardrail, and cooperates with the two fixed guardrails to form an effective integral arc-shaped guardrail to increase the safety of the structure. In this embodiment, the above-mentioned movable guardrail can also be provided in two pieces as needed, and is hinged to the fixed guardrails on both sides respectively.

[0026] In another specific embodiment, the inside of the bucket 4 is provided with a ladder extending from the bottom of the bucket 4 to the opening at the top of the bucket 4. In this way, it is convenient for the personnel in the bucket 4 to move or carry by the ladder.

[0027] In another specific embodiment, a movable platform trolley locking mechanism 6 is hinged at the semicircular notch, and the movable platform trolley locking mechanism 6 can be rotated to fasten the side wall of the top opening of the bucket 4.

[0028] Among them, in a further specific embodiment based on the above, the movable platform trolley locking mechanism 6 is a hook, which is hinged at the semicircular groove of the movable platform trolley 2, and a fixed baffle is provided on the upper edge of the bucket 4 near the movable platform trolley 2. After the hook is rotated, it can be hooked on the lower end of the fixed baffle, so that the connection between the bucket 4 and the movable platform trolley 2 is more reliable and tight.

[0029] Wherein, the above-mentioned hook is symmetrically provided with two according to the center line of the semicircular notch. In the present embodiment, the above-mentioned hook is provided with a locking mechanism operating handle 7 which is convenient for driving the hook to rotate, so as to facilitate operation.

In this way, the stability of the overall structure of the movable trolley guardrail 10 and the safety during use can be guaranteed by adding a slide bar. At the same time, the designed slide bar and movable safety rope 13 can further provide a protective means for users to fasten the safety belt, ensuring the safety of users passing the movable platform trolley 2.

[0031] As attached Figure 5 and attached Figure 6 As shown, in another specific embodiment, the lower side wall of the movable trolley guardrail 10 is provided with a circle of high skirting boards 14. In this way, the high skirting boards 14 can be used to increase the safety protection of the structure, prevent objects from falling into the shaft, and increase the stability of the structure.

[0032] In another specific embodiment, the movable platform trolley 2 includes several base channel steels 15, patterned steel plates 16 and movable trolley rollers 9. The upper end of the patterned steel plate 16 is used to install the movable trolley guardrail 10.

The bottoms of both ends of two base channel steels 15 are respectively installed with movable trolley rollers 9 through connecting angle steels 17. The movable trolley rollers 9 are clamped and slidably set in the closed track 1.

[0033] In this embodiment, a stiffening rib plate 20 for reinforcement is also installed on the connecting angle steel 17. In this way, the stiffening rib plate 20 can increase the reliability of the structure.

[0034] Among them, in a further specific embodiment based on the above, the movable trolley roller 9 adopts a pulley with a T-shaped side section, and the closed track 1 includes a closed side rail 19 and a closed steel plate 18. The opposite side walls of the closed side rails 19 on the left and right sides are respectively provided with a slide groove for the shrinking end of the T-shaped pulley to be clamped and slidably connected, and the opposite side walls of the closed side rails 19 on both sides and the ends close to or away from the shaft are all closed and wrapped by the closed steel plate 18. In this way, the slide grooves of the shrinking ends of the T-shaped pulleys on both sides of the movable platform trolley 2 are clamped and slidably connected to ensure the safe position limitation of the movable platform trolley 2, and the closed side rails 19 are closed and wrapped by the closed steel plate 18 to ensure the stability of the closed side rail 19 structure, and at the same time, it can prevent the movable trolley roller 9 from slipping off the closed side rail 19, and also prevent gravel from entering the closed side rail 19.

[0035] In another specific embodiment, a limit device 12 for limiting the moving range of the movable platform trolley 2 is provided on the closed track 1. In this way, the moving position of the movable platform trolley 2 is further limited, and the movable platform trolley is used to fix the position after the movable platform trolley stops, so as to facilitate positioning and limiting the movable platform trolley 2 according to the position requirements of the bucket 4 as needed. In this embodiment, a sealable and removable limit bolt can be set at the corresponding position of the side wall of the closed track 1, and the limit bolt is used as the limit device 12 to limit the moving range of the movable platform trolley 2, or the pulleys of the platform trolley 2 moved to the specified position are successively clamped and limited.

[0036] In another specific embodiment, the bottom of the closed track 1 located at the cradle pit is connected to a track support steel beam 11, and the two ends of the track support steel beam 11 are respectively fixed on the two sides of the cradle, and the left and right sides of the end of the closed track 1 away from the shaft are respectively anchored by a track fixing anchor rod 3 inserted into the bottom plate of the roadway. Among them, the track fixing anchor rod 3 adopts a mortar anchor rod. In this way, the end of the closed track 1 close to the shaft is supported and fixed by the track support steel beam 11, and the closed track 1 is further plugged and fixed by the track fixing anchor rod 3, which ensures the overall structural stability during the use of the platform, and is also an anti-overturning design.

[0037] The structure of the present invention is installed at the -280m horse head gate of the personnel shaft, and its functions include: after installation, it can meet the needs of personnel entering and exiting the -280m horizontal tunnel from the personnel shaft at any time, thus creating conditions for various operations in the -280m horizontal tunnel, including scientific research experiments, and the simultaneous construction of the shaft and the later -560m horizontal tunnel; after installation, it can meet the needs of loading and unloading some small tools, instruments and materials at the -280m horse head gate, ensuring that a large number of personnel can safely and reliably enter and exit the -280m horizontal tunnel from the shaft, and also ensuring that after the device is installed at the -280m horse head gate, the normal vertical transportation of the bucket 4 and other large equipment and materials in the shaft during the construction of the -560m horizontal tunnel will not be affected, and the two buckets 4 in the shaft can be vertically staggered, which will not affect the operating speed and safety status of the two buckets 4, thereby ensuring that the lifting capacity of the shaft and the production capacity of the two horizontal tunnels are not affected.

[0038] The installation position of the present invention is relatively special. This structure is installed at the horse head gate in the middle of the vertical shaft, which is 280m high from the wellhead and the well bottom. It is used for personnel to pass from the vertical shaft bucket 4 to the horizontal tunnel at the horse head gate or from the horizontal tunnel to the bucket 4 in the vertical shaft. The installation position is relatively special. The bucket 4 in the shaft can be vertically staggered without affecting the busy operation between each other.

[0039] The present invention is reliable in processing and installation, and requires very little maintenance. Due to the special installation location, great difficulty in maintenance, and high maintenance cost, relatively high requirements are placed on processing quality and installation quality. The service life is nearly four years, and very little maintenance is required during use. While ensuring the reliability of the overall wellbore anti-fall management, large maintenance amounts including disassembly, replacement, and electric welding are avoided.

[0040] The movable platform trolley 2 of the present invention can be freely extended and retracted. The shaft is the only passage for personnel to go up and down, and for the lifting and transportation of various materials and equipment and waste rock underground. The two buckets 4 in the shaft are busy shuttling up and down. Due to the narrow space in the shaft, various pipelines and facilities, the invention is required to be freely extended and retracted. When in use, the movable platform trolley 2 can be extended to dock with the bucket 4 and fixed reliably; after use, the movable platform trolley 2 can be retracted so that it is no longer extended, ensuring that there is a sufficient safety distance between the bucket 4 in the shaft and various surrounding facilities during operation.

[0041] The present invention has a novel structure, and the movable platform trolley 2 will not derail. Due to the particularity of the installation position and the purpose of use, the movable platform trolley 2 is absolutely not allowed to derail during use. Therefore, the general open track design form is abandoned during the design, and instead a closed, embedded track design is adopted, so that derailment and the like will not occur under any working conditions, ensuring the safety and reliability of the movable platform trolley 2 during its entire life cycle.

[0042] The present invention is easy to operate, because the movable platform trolley 2 is frequently used, so its easy operation is good and simple. The movable platform trolley 2 adopts an integral design and a track, and only one person needs to operate it with a little effort, and the operation is relatively simple.

[0043] The present invention will not tip over. Considering that the movable platform trolley 2 forms a cantilever structure when docking with the bucket 4, and that the movable platform trolley 2 will have different temporary loads such as personnel, materials, and tools under different working conditions, anti-tipping is a major consideration in the design. During construction, in addition to reliably welding and fixing the closed track 1 to the tunnel floor, two Φ20mm, L=2000mm long resin anchors are installed at the end of the platform away from the shaft, and the closed track 1 is firmly anchored to the tunnel floor with the anchor at the end that is easy to tilt.

[0044] The present invention has a large load-bearing capacity, and the integral and embedded structure ensures the overall structural stability of the platform to the greatest extent. The selection of high-strength rail wheels with larger diameters and steel sections with larger specifications enables the platform to carry a larger load and run smoothly.

[0045] The present invention can set multiple limit devices 12 as needed. In order to ensure that the movable platform trolley 2 does not roll or extend during use and rest, multiple limit devices 12 are set on the platform to flexibly control the displacement range, and the driving structure can effectively control the start and stop.

[0046] The locking mechanism 6 of the movable platform trolley of the present invention ensures that the platform and the bucket 4 are tightly combined, so as to ensure that when personnel enter and exit the bucket 4, the bucket 4 will not rotate or there will be a large gap between the bucket 4 and the edge of the platform, which will cause the risk of falling when personnel enter and exit the bucket 4. Two movable platform trolley locking mechanisms 6 are arranged at one end of the movable platform trolley 2 near the bucket 4 side, which are used to temporarily lock the bucket 4 and the movable platform trolley 2 when the bucket 4 is docked on the platform, so as to prevent rotation and separation, and ensure the safety of personnel entering and exiting the bucket 4.

[0047] The present invention has a reliable, specially designed movable trolley guardrail 10 and a movable safety rope 13. After the bucket 4 is docked with the movable platform trolley 2, in order to prevent people from falling, in addition to the movable trolley guardrail 10 on both sides of the movable platform trolley 2, an arc-shaped guardrail is arranged at the docking part of the bucket 4 and the movable platform trolley 2, so that people will not fall out of the bucket 4 due to slipping when entering and exiting the bucket 4. The design of the arc-shaped guardrail is combined with the movable trolley guardrail 10, firstly, it is convenient for people to pass through, and secondly, when the platform is not in use, the railing is closed to form a closed structure, so as to form a reliable guardrail between the lane and the shaft. In addition, in order to ensure the safety of people entering and exiting the bucket 4, a sliding rod and a movable safety rope 13 are also designed, and a movable safety belt hanging ring can be arranged on the movable safety rope 13, so that people can conveniently hang the safety belt when entering and exiting the bucket 4.

[0048] In order to reduce the number of limit devices, the platform is designed with a nested structure, wherein the external structure is a fixed device and the internal structure is a movable rail wheel structure. The external structure is a fixed baffle structure near one end of the bucket. When the internal structure is pushed to the extreme position, i.e., the fixed baffle position, the arc guardrail is in close contact with the bucket.

[0049] When the device of the present invention is used, considering the narrow space and special environment on site, in order to simplify the installation plan and reduce the safety risk of underground operations, this design minimizes the workload of underground processing and installation. The ground split processing, assembly and testing are adopted on site, and after passing the test, it is divided into several parts and transported to the underground for overall assembly and permanent fixation.

[0050] Split processing on the ground: Except for the closed steel plate 18 on the side close to the bucket 4, the closed track 1 of this structure is not permanently welded, and the whole is processed and connected (welded) on the ground. Bolts are temporarily used for connection on the ground to facilitate lifting and transportation by a hoist in the wellbore; the movable trolley guardrail 10 of the movable platform trolley 2 is processed into a whole according to the left and right sides and the arc-shaped guardrail, and the other parts except the railings and laying steel plates are processed and welded into a whole on the ground.

[0051] After the processing of each part is completed, it is assembled and tested on the ground. After the test run is passed, the closed track 1, track fixing anchor rod 3, patterned steel plate 16 and base channel steel 15 of the movable platform trolley 2, arc-shaped guardrail, movable trolley guardrail 10 are lowered in sequence and installed simultaneously underground.

[0052] Before installation, first lift the hoisting platform during shaft construction to the bottom plate of the -280m horse head gate as a working platform and safety protection facility. First measure and locate and determine the horizontal slope. After the closed track 1 and the movable platform trolley 2 are assembled underground, weld the end fixing steel plate. After the lifting bucket 4 is lowered to the working position for people to get on and off, check the relative position and horizontal state of the semicircular notch of the movable platform trolley 2 and the bucket 4, weld the closed track 1 to the track support steel beam 11, and install the track fixing anchor rod 3 at the rear end of the track.

[0053] Install the arc guardrail and the movable trolley guardrail 10, test the run again and determine and install the limit devices 12 on both sides of the closed track 1.

[0054] Laying the patterned steel plate 16 and high skirting board 14 of the movable platform trolley 2; Install the slide bar and the movable safety rope 13. When the test personnel pass through the movable platform trolley 2, they hang the safety belt into the safety rope ring of the movable safety rope 13 in advance, and then untie the safety belt after the test personnel pass through the mobile platform.

[0055] At this point, the telescopic ladder workers have completed the installation and debugging of the upper and lower platforms.

[0056] The present invention not only meets the requirements of -280m horizontal scientific research experiments, personnel entry and exit, and the lowering of small materials and tools, but also ensures the construction requirements of the personnel shaft without affecting the lifting efficiency of the shaft, directly saves nearly 40 days of construction time, effectively solves various concerns and safety risks in construction, greatly facilitates on-site construction organization, and has a significant effect. It can be actively promoted for use under similar construction conditions.
