[0002] During shaft drilling operations, a mixing system and an umbrella drill rig are typically installed at the wellhead, along with multiple maintenance platforms and ladders. The umbrella drill rig is a mechanized rock drilling device used in vertical shaft excavation, usually powered by compressed air and operated via hydraulic transmission. It is mainly used for drilling blasting holes, grouting holes, exploration holes, water exploration holes, and gas drainage holes in vertical shaft construction. The umbrella drill rig can be suspended below the shaft's waste rock dumping platform and moved using I-beams as transport tracks.

[0003] After each drilling operation, the umbrella-shaped drill rig needs to be lifted to the wellhead for maintenance. Existing maintenance platforms are mostly fixed near the wellhead, requiring personnel to stick their bodies out for maintenance, which is inconvenient and poses safety risks.

[0004] This utility model proposes a new solution. Utility Model Content

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A multifunctional maintenance platform includes a frame, a fixed platform connected to the top of the frame, a ladder connected to one side of the frame, and two rotatably connected extension platforms on the other side of the frame. A drive mechanism for driving the two extension platforms to rotate relative to each other is installed on the frame.

[0008] Preferably, each of the two extended platforms is connected to a second gear at one end near the frame, and the middle of the second gear is connected to a rotating shaft that is rotatably connected to the frame.

[0009] Preferably, the drive mechanism includes a motor mounted on the frame and a first gear connected to the output end of the motor, wherein the first gear and one of the second gears are drively connected.

[0010] Preferably, both the fixed platform and the extended platform are connected to a fence at their top.

[0011] Preferably, a protective door corresponding to the extended platform is installed on the side of the fixed platform away from the ladder.

[0012] Preferably, a telescopic platform is movably connected to the top of the extension platform at the end furthest from the frame.

[0013] Preferably, a pin connects the extension platform and the telescopic platform.

[0014] Preferably, the top of the extension platform has a plurality of first connecting holes that cooperate with the pin, and the top of the telescopic platform has a second connecting hole that cooperates with the pin.

[0015] Preferably, the top of the pin is connected to a baffle located at the top of the telescopic platform, and the top of the baffle is connected to a handle.

[0016] Preferably, the top of the extension platform has two symmetrically distributed limiting grooves, and the bottom of the telescopic platform is fixedly connected with an L-shaped slider that cooperates with the limiting grooves.

[0017] The beneficial technical effects of this utility model are as follows: According to the multi-functional maintenance platform of this utility model, through the setting of the extension platform and the drive mechanism, the drive mechanism can drive the two extension platforms to move away from each other and closer together. When it is necessary to maintain the umbrella drill frame, the two extension platforms are controlled to move closer to each other, which facilitates a more comprehensive maintenance of the umbrella drill frame and is safe and efficient. After the maintenance is completed, the two extension platforms are controlled to move away from each other, which will not affect the lifting of other items at the shaft opening.

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-6 As shown, the multifunctional maintenance platform provided in this embodiment includes a frame 1, a fixed platform 2 connected to the top of the frame 1, a ladder 3 connected to one side of the frame 1, and two rotatably connected extension platforms 4 on the other side of the frame 1. A drive mechanism for driving the two extension platforms 4 to rotate relative to each other is installed on the frame 1. Through the arrangement of the extension platforms 4 and the drive mechanism, the drive mechanism can drive the two extension platforms 4 to move away from each other and closer together. When it is necessary to maintain the umbrella drill frame, the two extension platforms 4 are controlled to move closer to each other, which facilitates a more comprehensive maintenance of the umbrella drill frame and is safe and efficient. After the maintenance is completed, the two extension platforms 4 are controlled to move away from each other, so as not to affect the lifting and lowering of other items at the shaft opening.

[0027] In this embodiment, as Figure 2 , Figure 4 and Figure 5 As shown, each of the two extension platforms 4 has a second gear 5 connected to one end near the frame 1. A rotating shaft 6, rotatably connected to the frame 1, is connected to the middle of each second gear 5. The drive mechanism includes a motor 7 mounted on the frame 1 and a first gear 8 connected to the output end of the motor 7. The first gear 8 and one of the second gears 5 are connected in a transmission relationship. Through the arrangement of the motor 7, the first gear 8, and the second gear 5, the motor 7 drives the first gear 8 to mesh with the second gears 5 on the two extension platforms 4, thereby achieving relative movement between the two extension platforms 4.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment, both the top of the fixed platform 2 and the extended platform 4 are connected to fences, and a safety door 9 corresponding to the extended platform 4 is installed on the side of the fixed platform 2 away from the ladder 3. The fences and safety door 9 ensure the safety of workers.

[0029] In this embodiment, as Figure 4 , Figure 5 and Figure 6As shown, in an optional embodiment, a telescopic platform 10 is movably connected to the top of the end of the extension platform 4 away from the frame 1. A pin 11 connects the extension platform 4 and the telescopic platform 10. The top of the extension platform 4 has a plurality of first connecting holes 12 that cooperate with the pin 11. The top of the telescopic platform 10 has a second connecting hole 13 that cooperates with the pin 11. A baffle 14 located on the top of the telescopic platform 10 is connected to the top of the pin 11. A handle 15 is connected to the top of the baffle 14. Two symmetrically distributed limiting grooves 16 are provided on the top of the extension platform 4. An L-shaped slider 17 that cooperates with the limiting groove 16 is fixedly connected to the bottom of the telescopic platform 10. It should be noted that by setting up the telescopic platform 10, the length of the extension platform 4 can be extended, thus solving the problem of using the umbrella drill frame at excessive distances. At the same time, the extension platform 4 occupies a smaller volume, making it convenient for use in narrow spaces at the shaft opening. By setting up the pin 11, the first connecting hole 12, and the second connecting hole 13, the extension function can be achieved by changing different hole positions, which is simple and reliable. The limiting slide groove 16 and the L-shaped slider 17 prevent the telescopic platform 10 from detaching from the extension platform 4.

[0030] In this embodiment, as Figures 1-6 As shown, the working process of the multifunctional maintenance platform provided in this embodiment is as follows:

[0031] Step 1: When maintenance is required, start motor 7 to drive first gear 8 to drive second gear 5 on two extension platforms 4 to mesh with each other, thereby realizing relative movement of the two extension platforms 4, so that extension platforms 4 are close to umbrella drill frame. At this time, workers open protective door 9 to enter extension platform 4 to maintain umbrella drill frame.

[0032] Step 2: When the distance is insufficient, pull out the pin 11, push out the telescopic platform 10, and then install the pin 11.

[0033] Step 3: After the maintenance is completed, the worker leaves the extension platform 4 and starts the starter motor 7 so that the two extension platforms 4 are relatively far apart.

[0034] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
