Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically, to an underground excavation extension work platform. Background Technology

[0002] Currently, rock drilling rigs are commonly used in tunnel construction. Most existing rock drilling rigs are assembled by welding, which makes them non-disassembly. Once they are scrapped, they are abandoned, resulting in material waste. Furthermore, the dimensions are fixed after assembly, making it difficult to use them interchangeably for two different construction projects. As a result, the rigs are left idle for a long time, leading to low utilization.

[0003] Moreover, traditional metal platforms have high production costs, and the folding process is cumbersome, requiring the disassembly of multiple connectors (such as screws and hinge locks), which further increases costs. Once unfolded, they lack stability and are prone to wobbling. Furthermore, when the space inside the hole is narrow (width > 2.5m but the equipment needs to be centered), the working surface of traditional platforms is insufficient (< 1.8m). The extensibility of manually erected steel pipe scaffolding is poor, making it impossible to quickly widen the platform.

[0004] Therefore, it is necessary to propose an extended underground excavation work platform to solve the problems of existing underground excavation work platforms, such as low versatility, non-adjustable work positions, inability to adapt to ground conditions, and inconvenience in movement. Utility Model Content

[0005] This utility model provides an underground excavation extension platform that is simple to operate, can deploy a working platform, and has a stable structure, in order to solve the above-mentioned technical problems.

[0006] According to one aspect of the present invention, an underground excavation extension work platform is provided, which is installed on a platform of a vehicle body. Positioning posts are provided at the four corners of the platform. The underground excavation extension work platform includes a mounting frame, an intermediate frame, and an extension frame. Limiting posts are inserted into the positioning posts. The mounting frame is supported on the top of the positioning posts and the limiting posts are inserted through the mounting frame. The intermediate frame is installed on the mounting frame. Extension frames are connected to both sides of the mounting frame. Limiting edges for limiting the rotation angle of the extension frames are provided on the mounting frame.

[0007] Based on the above scheme, the limiting edge is a plug rod, the mounting frame is made of steel pipes joined together, and the outer steel pipe of the mounting frame is open to fit the plug rod. When the expansion frame is rotated to a horizontal position, the expansion frame is supported on the plug rod.

[0008] Based on the above scheme, the limiting edge is a protrusion, the mounting frame is made of overlapping steel pipes, the limiting edge is located on the outside of the mounting frame, and when the expansion frame is rotated to a horizontal position, the expansion frame overlaps the protrusion.

[0009] Based on the above-mentioned solution, the mounting frame is preferably made of steel pipes joined together, and an anti-slip net is provided on the end face of the mounting frame that extends beyond the platform.

[0010] Based on the above-mentioned scheme, the expansion frame includes a frame made of welded steel pipes, and an adapter sleeve is rotatably fitted on the mounting frame. The adapter sleeve is connected to the expansion frame through a connecting plate.

[0011] Based on the above scheme, a preferred embodiment is that multiple limiting posts are welded at intervals on the outer side of the mounting frame.

[0012] Based on the above scheme, a preferred embodiment is that a receiving cavity is formed between the mounting frame and the platform, and multiple raising frames are inserted into the receiving cavity.

[0013] This utility model discloses an underground excavation extension work platform, which adopts a combination of vehicle body and work platform for easy and rapid movement. The platform on the vehicle body is equipped with positioning posts with limiting columns. These limiting columns, inserted into the mounting frame, quickly lock the relative position of the mounting frame and the vehicle body. An intermediate frame on the mounting frame accommodates the operating height of curved tops. The space between the mounting frame and the platform allows for the use of multiple extension frames, enabling height adjustment without occupying space. Furthermore, the connection between the extension frame and the mounting frame allows for rapid expansion of the lateral working surface, facilitating construction. The extension frame and the lifting frame are connected in a detachable or rotatable manner, making assembly and disassembly more convenient. Attached Figure Description

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0031] Please see Figure 1 and combined Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides an underground excavation extension work platform, such as... Figure 1 As shown, the work platform is mounted on platform 101 of the vehicle body. The vehicle body adopts an engineering vehicle or other structure with wheels on the bottom to facilitate the rapid transfer of the work platform.

[0032] In this invention, vertical positioning posts 102 are fixed at the four corners of the platform 101, and limiting posts 103 are inserted into the positioning posts 102. The positioning posts 102 are used to support the working frame, while the limiting posts 103 are used to limit the left and right movement of the working frame.

[0033] The work platform includes a mounting frame 104, an intermediate frame 105, and an extension frame 106. The mounting frame 104 is supported on the top of the positioning column 102 to form an installation base, while the safety limit column 103 is inserted through the mounting frame 104 to fix the mounting frame 104 and ensure that the relative position of the mounting frame 104 and the vehicle body is locked. Preferably, a positioning rod 115 is also provided at the center of the platform 101.

[0034] The intermediate frame 105 of this utility model is installed on the mounting frame 104, forming a structure that is high in the middle and low on both sides. The intermediate frame 105 provides a height difference for construction at the top of the tunnel. The mounting frame 104 is connected to the two sides of the expansion frame 106. The mounting frame 104 is provided with a limiting edge for limiting the rotation angle of the expansion frame 106. Through the function of the limiting edge, stable support for the bracket is achieved, ensuring a stable connection between the two expansion frames 106 and the mounting frame 104.

[0035] In the first preferred embodiment of this utility model, the mounting frame 104 is welded from steel pipes. The outer steel pipe is open and the limiting edge adopts the structure of the insert rod 107, which is inserted into the opening of the steel pipe of the mounting frame 104 to form a support platform 101, so as to form a horizontal support for the expansion frame 106 and expand the operating space.

[0036] The intermediate frame 105 of this utility model is fixed on the mounting frame 104 to adapt to the working height requirements of the arc-shaped top.

[0037] Among them, the expansion frame 106 and the mounting frame 104 can be connected by the expansion frame 106 directly overlapping the support platform 101 formed by the insertion rod 107 of the mounting frame 104.

[0038] When the extension frame 106 is directly attached to the support platform 101 formed by the insert rod 107 of the mounting frame 104, the extension frame 106 includes a frame welded from steel pipes, and multiple limiting posts 103 are welded at intervals on the outer side of the mounting frame 104. In use, the extension frame can be laid flat on the support platform 101 as needed to expand the operating surface. Simultaneously, the extension frame 106 is inserted into the limiting posts 103, which effectively ensure the stability of the extension frame 106. When not in use, the insert rod 107 can be pushed back into the pipe, allowing the free end of the extension frame 106 to be attached to the intermediate frame 105, and the other end of the extension frame 106 to abut against the limiting posts 103, thus reducing the overall width and allowing the extension frame 106 to be stored. For detailed structure, please refer to [link to specific details]. Figure 5 , Figure 6 and Figure 7 As shown.

[0039] In a second preferred embodiment of this utility model, the expansion frame 106 and the mounting frame 104 can be connected by an adapter.

[0040] When the expansion frame 106 and the mounting frame 104 are connected by an adapter, the expansion frame 106 includes a frame made of welded steel pipes, and the mounting frame 104 is rotatably fitted with an adapter sleeve 108. The adapter sleeve 108 is connected to the expansion frame 106 through a connecting plate 114. By pushing the expansion frame 106, the expansion frame 106 can be rotated relative to the mounting frame 104. Thus, when it is not necessary to expand the operating range, the free end of the expansion frame 106 can be attached to the intermediate frame 105 to adapt to narrower tunnels.

[0041] The limiting edge of this utility model adopts the structure of a protrusion 112. That is, the limiting edge is a protrusion 112 welded to the outside of the mounting frame 104, which is made of steel pipes joined together.

[0042] When the extension frame 106 is in a horizontal position, it directly overlaps the protrusion 112 to achieve limiting support. It should be noted that in order to ensure the effectiveness of the protrusion 112, the protrusion 112 extends as far as possible in the width direction of the extension frame 106, and the protrusion 112 and the mounting frame 104 are connected by welding or other methods.

[0043] To ensure the safety of the overall operation and minimize costs, the extension frame 106, mounting frame 104 and intermediate frame 105 of this utility model are covered with anti-slip netting 111 on the end face used to support the operator.

[0044] Furthermore, in order to meet the needs of construction at different heights, this utility model also forms a receiving cavity 109 between the mounting frame 104 and the platform 101. Multiple raising frames 110 can be inserted into the cavity to adapt to different construction height requirements. A positioning rod is provided in the middle of the platform 101, which passes through the intermediate frame 105 and the raising frame 110 to achieve secondary positioning and ensure its stability.

[0045] This utility model achieves rapid movement and positioning through the modular combination of the vehicle body and the work platform. The cavity 109 between the mounting frame 104 and the platform 101 can store the extension frame 110, making the platform height adjustable without occupying extra space; the rotating or detachable design of the extension frame 106 facilitates the lateral expansion of the working surface and improves construction efficiency; the limiting edge (insertion rod 107 or protrusion 112) ensures the stability of the extension frame 106 after it is unfolded, and the anti-slip net 111 further ensures the safety of operation.

[0046] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
