Description

Technical Field

[0001] The utility model relates to the technical field of support frames, in particular to a mine-used ladder-shaped support frame with a warning plate. Background Art

[0002] During the mining process, mining support frames are one of the important equipment to ensure the safe operation of miners.

[0003] Mining support frames often lack flexibility in length adjustment and are difficult to adapt to the support needs of different mine tunnel widths. This requires miners to frequently replace support frames of different sizes when building support structures, which not only increases operating costs but also reduces work efficiency. In addition, some support frames are prone to loosening or instability during the length adjustment process, posing potential risks to miners' safe operations. Secondly, mining support frames are also insufficient in terms of stability. Due to the complex and changeable mining environment, support frames need to withstand the impact of various external forces such as ground pressure and water pressure. However, some support frames lack sufficient stability in design and are prone to tipping or displacement, resulting in support failure and posing a serious threat to the lives of miners.

[0004] Therefore, in response to this problem, the present invention provides a mine ladder support frame with a warning plate. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art and to propose a mine ladder support frame with a warning plate.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a mine trapezoidal support frame with a warning plate, comprising a fixed plate, support brackets are symmetrically arranged on both sides of the fixed plate through a rotating axis, and cross bar 1 and cross bar 2 are movably connected on both sides of the two support brackets, and a threaded sleeve is provided on the side of the cross bar 2, and the side of the cross bar 1 is fixedly connected to threaded rod 1, and the threaded sleeve and threaded rod 1 are threadedly connected for length adjustment, and the sides of the cross bar 1 and the limiting threaded rod 2 are respectively threadedly connected to the limiting threaded rod 2, and the tops of the two fixed plates are clamped with docking seats, and the top of the docking seat is fixedly connected to a placing platform, and one side of the fixed plate is fixedly connected to a warning sign by bolts.

[0007] Preferably, the top of the fixing plate is symmetrically provided with card slots, and the card slots match the docking seat.

[0008] Preferably, a mounting groove is provided on one side of the fixing plate, and the mounting groove matches the warning sign and is used for hanging the warning sign.

[0009] Preferably, a supporting leg is provided at the bottom of the supporting bracket, and two mounting holes are provided on the supporting leg at equal distances.

[0010] Preferably, a tightening seat is fixedly connected to the surface of the threaded rod 1, and the tightening seat is located on the side of the cross bar 1.

[0011] Preferably, the second limiting threaded rod passes through one end of the first cross bar and is connected to a limiting ring through a thread, and the limiting ring is used to limit the position of the second limiting threaded rod.

[0012] Compared with the prior art, the utility model provides a mine ladder support frame with a warning plate, which has the following beneficial effects:

[0013] 1. The mine trapezoidal support frame with a warning plate realizes flexible adjustment of the support frame length through the threaded connection design of cross bar 1, cross bar 2, threaded sleeve and threaded rod 1, which can meet the support needs of different mine tunnel widths. At the same time, the support legs at the bottom of the support frame and the mounting holes opened at equal distances not only increase the contact area between the support frame and the ground, improve the overall stability, but also make it easy to firmly fix the support frame to the ground to prevent it from tipping over or displacement in complex mining environments.

[0014] 2. The mine trapezoidal support frame with a warning plate can clearly display safety warning information through the fixed connection between the installation slot and the bolt, reminding miners to pay attention to work safety and effectively reducing the risk of mine accidents. At the same time, the tightening seat design on the surface of the threaded rod makes it easier and more convenient to adjust the length of the support frame. Miners only need to rotate the tightening seat to achieve precise adjustment of the length of the support frame, which greatly improves work efficiency. In addition, the quick-connection design of the slot and the docking seat also simplifies the assembly process of the support frame, allowing miners to build the support structure more quickly and provide timely safety protection for mining operations.
