Description

Technical Field

[0001] This utility model relates to a multi-functional platform suitable for various tunnel pipe roof drilling rigs, belonging to the field of tunnel construction technology. Background Technology

[0002] With the rapid development of railway construction, more and more tunnels inevitably need to pass under existing structures such as railways, highways, and buildings. The disturbance caused by excavation may cause certain settlement and deformation of existing structures, endangering their safety. When the surrounding rock strength of the tunnel is good, the traditional construction method is to use φ108mm large pipe roofs in conjunction with CRD, CD, or double-sidewall pilot tunnel methods. Although this φ108mm large pipe roof is beneficial to the stability of the surrounding rock and ensures construction safety, it is difficult to construct with large equipment, has a long construction period, and easily leads to an increase in material and labor costs. To ensure the construction of large equipment, the φ108mm large pipe roof needs to be enlarged and lengthened. However, traditional crawler drilling rigs are not suitable for constructing large and long tunnel pipe roofs, requiring the use of DM160 anchor drilling rigs. However, there is currently no suitable drilling rig operating platform for large tunnel pipe roof construction. Therefore, it is necessary to invent an operating platform to meet the requirements of DM160 anchor drilling rig construction, so as to achieve the construction of larger and longer pipe roofs. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model provides a multi-functional platform for a tunnel large pipe roof drilling rig with a simple structure that can be applied to pipe roof drilling of different cross sections and heights.

[0004] This utility model is achieved through the following technical solution: a multi-functional platform suitable for various tunnel pipe roof drilling rigs, characterized by: a base, a lifting frame, and an operating platform. The base includes multiple I-beams laid longitudinally along the tunnel, and two I-beam tracks laid transversely along the tunnel on the I-beams. The lifting frame includes a main platform and a drilling rig platform. The main platform includes four rectangular columns, with the bottoms of the four columns reinforced by I-beams. The two columns on the left and right sides of the main platform, along the tunnel longitudinal direction, are horizontally connected by multiple steel pipes and scissor bracing is provided using steel pipes. The main platform is slidably mounted on the two I-beam tracks. The drilling rig platform is located inside the main platform. The columns of the drilling rig platform and the main platform are detachably connected. The upper ends of the four columns of the main platform are respectively equipped with hand-operated hoists connected to the four corners of the drilling rig platform. The operating platform is movably mounted on one side of the drilling rig platform, and a fence is provided around the operating platform.

[0005] In this invention, the upper part of the drilling rig platform is used to place the DM160 anchoring drilling rig, allowing construction personnel to stand on the operating platform for work. The lifting frame can move left and right along the I-beam track under external force. During pipe roof drilling, the drilling rig platform and the main frame's columns are fixedly connected to ensure construction safety. After disconnecting the drilling rig platform from the main frame's columns, the drilling rig platform can be raised and lowered by operating the hand-operated hoists, adjusting the drilling rig's working height.

[0006] Furthermore, to ensure the stability of the platform, all the columns of the main platform are made of I-beams.

[0007] Furthermore, the drilling rig platform includes a front frame and a back frame. Both the front frame and the back frame are composed of two H-beams that are spaced apart vertically and welded together. Both ends of the front frame and the back frame are bolted to the columns of the main platform. The two ends of the operating platform pass through the gaps between the upper and lower H-beams of the front frame and the back frame, respectively.

[0008] Furthermore, the operating platform includes multiple steel pipes mounted on the drilling rig frame and steel grating or wooden planks covering the top of the steel pipes.

[0009] Furthermore, the two ends of the I-beams that connect to and reinforce the two columns on the bottom of the left and right sides of the main frame extend outwards, and the main frame slides with the I-beam track through these extended ends.

[0010] Furthermore, all the I-beams used are 22# I-beams.

[0011] The beneficial effects of this utility model are as follows: The drilling rig platform of this utility model has an adjustable height, which can be easily adjusted using a hand-operated hoist. The lifting frame can move left and right along the I-beam track. By adjusting the height of the drilling rig platform and the lateral position of the sliding lifting frame, it can be used for drilling pipe roofs of different cross-sections and heights, effectively solving the problem of large pipe roof construction. The operating platform is set on the drilling rig platform and can be raised and lowered with it, facilitating operation and construction work. This utility model has a simple structure, high overall stability, and can ensure the safety of construction operations. This utility model has a modular structure; the base, lifting frame, and operating platform are simple to assemble, easy to disassemble, and easy to transport. Attached Figure Description

[0016] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0017] As shown in the attached diagram, a multi-functional platform suitable for various tunnel pipe roof drilling rigs includes a base, a lifting frame, and an operating platform 6. The base is constructed using 22# I-beams and includes multiple I-beam support beams 1 laid longitudinally along the tunnel. The I-beam support beams 1 are spaced apart, with the spacing determined by the tunnel construction conditions. Two I-beam rails 2 are laid transversely along the tunnel on the I-beam support beams 1. The lifting frame includes a main platform and a drilling rig platform 5. The main platform includes four rectangular columns 3, preferably made of 22# I-beams. The bottoms of the four columns 3 are reinforced by two transverse connecting reinforcing I-beams 8 and two longitudinal connecting reinforcing I-beams 9. The transverse connecting reinforcing I-beams 8 and longitudinal connecting reinforcing I-beams 9 are also preferably made of 22# I-beams. The two columns 3 on the left and right sides of the main platform along the tunnel longitudinal direction are horizontally connected by multiple horizontal connecting steel pipes 10. The vertical spacing of the horizontal connecting steel pipes 10 is 1.5 meters, which can be increased as needed according to site conditions. φ60 steel pipes are used as scissor braces 11 and welded to the columns 3. The main platform is slidably mounted on two I-beam rails 2. By applying a thrust to the main platform, it can be moved along the I-beam rails 2. The drilling rig platform is located inside the main platform, and the drilling rig platform is detachably connected to the columns 3 of the main platform by bolts. Each of the four uprights 3 of the main frame is equipped with a hand-operated hoist 4, which is connected to the four corners of the drilling rig frame 5. The operating platform 6 is movably mounted on one side of the drilling rig frame 5, and a safety fence 7 is installed around the operating platform 6.

[0018] To simplify the structural design, in this embodiment, the drilling rig frame 5 includes a front frame and a back frame. The front frame is located on the side of the main frame closer to the borehole, and the back frame is located on the side of the main frame farther from the borehole. The front and back frames have the same structure, each including an upper H-beam 5.1 and a lower H-beam 5.2 spaced apart vertically. The upper H-beam 5.1 and the lower H-beam 5.2 are fixed together by welding two short H-beams. The two ends of the front frame are bolted to two columns 3 on the side of the main frame closer to the borehole, and the two ends of the back frame are bolted to two columns 3 on the side of the main frame farther from the borehole. The two ends of the operating platform 6 pass through the gaps between the upper H-beam 5.1 and the lower H-beam 5.2 of the front and back frames, respectively. The H-beams used in the drilling rig frame 5 are preferably #22 H-beams.

[0019] To facilitate installation and disassembly, in this embodiment, the operating platform 6 includes multiple steel pipes 6.1 mounted on the drilling rig frame 5 and steel gratings or wooden boards 6.2 fully laid on the upper part of the steel pipes 6.1.

[0020] Considering the simplicity and reliability of the structural design, in this embodiment, the two ends of the longitudinal connecting reinforcement I-beams 9 of the two columns 3 at the bottom of the left and right sides of the main frame extend outwards, and the main frame slides with the I-beam track 2 through the extended ends.

[0021] When using this invention for construction, the DM160 anchoring drill for pipe roof drilling is placed on the upper part of the drilling rig frame 5, and the construction personnel can operate the drill from the operating platform 6. During pipe roof drilling, the drilling rig frame 5 is fixedly connected to the main frame column 3. After releasing the bolts between the drilling rig frame 5 and the main frame column 3, the drilling rig frame 5 can be raised and lowered by operating the hand-operated hoists 4. After the drilling rig frame 5 is raised or lowered to the working position, it is re-bolted and fixed to the main frame column, and drilling can then commence. When it is necessary to move the lateral position of the lifting frame, external force is applied to the main frame, allowing the lifting frame to move along the I-beam track 2. This invention, by adjusting the height of the drilling rig frame and sliding the lateral position of the lifting frame, is applicable to pipe roof drilling of different cross-sections and heights.

[0022] The other parts in this embodiment are all existing technologies and will not be described in detail here.
