[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figure 1-3 As shown, a safety protection device for underground operations includes a plurality of columns 1 and a guardrail assembly 2.

[0033] The column 1 and the guardrail assembly 2 are connected by a connecting piece, which includes a connecting plate 3 and a rotating shaft 10. The connecting plate 3 is rotatably connected to the column 1 and the inner wall of the guardrail assembly 2 through the rotating shaft 10. A through hole 4 is provided on the inner wall of the connecting plate 3, and a locking assembly 6 for limiting the rotation of the rotating shaft 10 is provided inside the column 1 and the guardrail assembly 2. The locking assembly 6 includes an I-shaped plate 9 and a limit plate 12. The limit plate 12 is fixedly connected to the top of the rotating shaft 10. The outer wall of the limit plate 12 is fixed with teeth 11. The inner wall of the I-shaped plate 9 near the limit plate 12 is provided with a tooth groove meshing with the teeth 11.

[0034] When the tooth groove is disengaged from the tooth 11, the limit plate 12, the rotating shaft 10 and the connecting plate 3 can all rotate along the axis of the rotating shaft 10 as the rotation center, so that the rotation angle of the connecting plate 3 can be adjusted according to the actual on-site installation requirements, so that the column 1 and the railing assembly 2 can be installed and connected in a non-straight line. After the adjustment is completed, the column 1 and the connecting plate 3 of the railing assembly 2 are fitted together so that the two through holes 4 coincide with each other. At this time, a bolt is passed through the two through holes 4, and a nut is screwed into the end of the bolt for tightening. At this point, the installation of a set of columns 1 and railing assemblies 2 is completed.

[0035] The device is provided with a connecting plate 3, a rotating shaft 10, teeth 11 and tooth grooves, and utilizes the rotation of the connecting plate 3 and the rotating shaft 10 to make the installation connection between the column 1 and the guardrail assembly 2 not be in the same straight line, thereby realizing irregular installation, allowing the device to adjust the range according to the terrain conditions on site, thereby improving the flexibility of the device, and utilizing the cooperation of the teeth 11 and the tooth grooves to maintain the current angle between the connecting plate 3 and the rotating shaft 10 unchanged, thereby improving the stability of the device.

[0036] like Figure 2 As shown, a mounting base plate 5 is welded to the bottom of the column 1, and a plurality of threaded holes are formed on the inner wall of the mounting base plate 5.

[0037] Make the installation base plate 5 fit the ground, and screw the bolts through the threaded holes into the ground to ensure the stability of the device.

[0038] like Figure 3 As shown, the inner walls of the column 1 and the guardrail assembly 2 are both provided with a slide groove 7, the I-shaped plate 9 is slidably fitted on the inner wall of the slide groove 7, the top of the I-shaped plate 9 is buckled with a spring 8, and the other end of the spring 8 is buckled to the inner walls of the column 1 and the guardrail assembly 2.

[0039] Move the I-shaped plate 9 upward along the inner wall of the slide groove 7, and the spring 8 will be elastically deformed under the force, thereby driving the tooth groove and the tooth 11 to disengage, so that the connecting plate 3 and the rotating shaft 10 can rotate along the axis of the rotating shaft 10. After the angle between the connecting plate 3 and the rotating shaft 10 is determined, release the I-shaped plate 9, and the I-shaped plate 9 will drop under the elastic force of the spring 8, so that the tooth groove and the tooth 11 will mesh again, and the connecting plate 3 and the rotating shaft 10 can no longer rotate.

[0040] By setting a spring 8 and an I-shaped plate 9, when the rotation angle of the connecting plate 3 and the rotating shaft 10 needs to be adjusted, it is only necessary to lift the I-shaped plate 9 upwards to disengage the tooth groove from the tooth 11. After the adjustment is completed, the I-shaped plate 9 is released, and the I-shaped plate 9 can be reset under the elastic force of the spring 8, thereby simplifying the operation steps of the device and improving the convenience of use and installation efficiency of the device.

[0041] Embodiment 2:

[0042] A safety protection device for underground operations. This embodiment makes the following improvements on the basis of embodiment 1: Figure 4 and Figure 5 As shown:

[0043] The guardrail assembly 2 includes a guardrail 13 and a handle 14. The handle 14 is slidably fitted on the side wall of the guardrail 13. The inner walls of the guardrail 13 and the handle 14 are both fixed with a protective net 16.

[0044] The inner wall of the guardrail 13 is connected with a threaded rod 18 through a thread, and a strip groove 17 is provided on the inner wall of the guardrail 2 15 close to the strip groove 13. The end of the threaded rod 18 away from the strip groove 17 passes through the guardrail 13 and is fixedly connected with the handle 14. The end of the threaded rod 18 close to the strip groove 17 is fixedly connected with an anti-slip pad 19, and the threaded rod 18 is slidably fitted on the inner wall of the strip groove 17.

[0045] In this embodiment: rotating the handle 14 drives the threaded rod 18 and the anti-skid pad 19 to approach the strip groove 17 or move away from the strip groove 17. When the threaded rod 18 and the anti-skid pad 19 move away from the strip groove 17, the second guardrail 15 can slide along the side wall of the first guardrail 13 without restriction, so that the overall length of the first guardrail 13 and the second guardrail 15 can be adjusted as needed; after the adjustment is completed, rotating the handle 14 again drives the threaded rod 18 and the anti-skid pad 19 to approach the strip groove 17 until the anti-skid pad 19 fits with the inner wall of the strip groove 17. At this time, the second guardrail 15 is restricted and cannot move further.

[0046] By setting guardrail 1 13 and guardrail 2 15, the device can flexibly adjust the distance between the two columns 1 according to the needs of on-site installation, so that the device can meet the needs of both rectangular and irregular structures, and can avoid the guardrail assembly 2 being subject to length restrictions when splicing irregular structures, thereby improving the applicability of the device.

[0047] Working principle: when it is necessary to splice into an irregular geometric structure, first fix all the columns 1, then fit the installation base plate 5 with the ground, then pass the bolts through the threaded holes and screw them into the ground to complete the installation of the columns 1, and then adjust the angle of the connecting plate 3 as needed, that is, lift the I-plate 9 upwards so that the tooth grooves are disengaged from the teeth 11, and the spring 8 is elastically deformed under force. At this time, the connecting plate 3, the rotating shaft 10 and the limit plate 12 can rotate along the axis of the rotating shaft 10 as the rotation center. After the adjustment is completed, release the I-plate 9, and use the elastic action of the spring 8 to drive the I-plate 9 to move downward, and the tooth grooves are meshed with the teeth 11 again, so that the connecting plate 3 and the rotating shaft 10 can maintain the current angle unchanged, and then the column 1 and the connection on the railing 13 or the railing 2 15 are The plates 3 are fitted so that the two through holes 4 overlap, and then a bolt is passed through the two through holes 4 and locked with a nut, and then the handle 14 is rotated to drive the threaded rod 18 and the anti-skid pad 19 to disengage from the strip groove 17, and then the movable guardrail 13 or guardrail 2 15 is adjusted according to the spacing between the two columns 1 until guardrail 13 or guardrail 2 15 can be connected to the other column 1. After the overall length of guardrail 13 and guardrail 2 15 is determined, the handle 14 is rotated again to drive the threaded rod 18 and the anti-skid pad 19 to move toward the strip groove 17 until the anti-skid pad 19 fits with the inner wall of the strip groove 17, so that guardrail 13 and guardrail 2 15 maintain their current positions unchanged, and the above steps are repeated until all the columns 1 and guardrail assemblies 2 are completely connected and fixed.

[0048] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
