Rotating the rotating block drives the threaded column to rotate, driving the extrusion block to fix the light well wall, and the steel pipe threaded sleeve is threadedly connected to the steel pipe column guardrail.

[0006] The technical solution to achieve the purpose of the utility model is: a non-ground-to-ground light well edge guardrail base, including a well flange, four lower steel plates are attached to the top of the well flange, the tops of the four lower steel plates are all attached to upper steel plates, the four lower steel plates and the four upper steel plates are each provided with an adjustment slot, the four lower steel plates and the four upper steel plates are each fixed by two bolts, the adjustment slots are matched with the bolts, the tops of the four upper steel plates are each fixedly connected to a steel pipe threaded sleeve, and steel pipes are each sleeved on the circumferential outer walls of the four steel pipe threaded sleeves.

[0007] In some embodiments, one side of each of the four lower steel plates is fixedly connected with elastic anti-slip rubber.

[0008] In some embodiments, the four lower steel plates and the four upper steel plates are all in an "L" shape.

[0009] In some embodiments, a threaded hole is opened on one side of the four upper steel plates, and a threaded column is screwed into the four threaded holes. One end of the four threaded columns is fixedly connected to an extrusion block, and the other end of the four threaded columns is fixedly connected to a rotating block.

[0010] In some embodiments, two sliding holes are provided on one side of the four upper steel plates, and limiting columns are slidably connected in the eight sliding holes, and one end of each of the two limiting columns is fixedly connected to the extrusion block.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] The utility model discloses a device for protecting the railing base, which is divided into an upper steel plate and a lower steel plate. The upper steel plate and the lower steel plate can adjust the width of the railing in multiple gears by adjusting the slots to make them match the thickness of the conventional flip-up wall. The adjusting slots on the upper steel plate and the lower steel plate are fixed by bolts after being overlapped. The elastic non-slip rubber on the lower steel plate fits the flip-up wall, effectively preventing the vertical displacement of the steel plate and providing a certain buffer to protect the wall. The rotating block drives the threaded column to rotate, driving the extrusion block to fix the wall of the light well. The upper steel plate is provided with a reserved steel pipe threaded sleeve, which can be connected with the steel pipe column guardrail thread. The four-sided enclosure makes the temporary railing protection stable and reliable, realizes the protection and warning of the light well, and is easy to install and disassemble, can be reused, and improves the use efficiency.

[0013] The invention solves the problem that, when protecting existing light wells, most of them adopt conventional edge protection railings directly placed on the roof, which is inconvenient to protect and install different light wells, resulting in waste of protection materials and failing to ensure the life safety of workers during disassembly.

[0019] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a non-ground-to-ground light well edge protection railing base through improvement. The technical solution of the utility model is:

[0021] Embodiment 1:

[0022] like Figure 1-Figure 2 As shown, a non-ground-to-ground light well edge guardrail base includes a shaft flange 1, and four lower steel plates 2 are attached to the top of the shaft flange 1. The tops of the four lower steel plates 2 are all attached to upper steel plates 3. Adjustment slots 4 are opened on the four lower steel plates 2 and the four upper steel plates 3. The four lower steel plates 2 and the four upper steel plates 3 are all fixed by two bolts 5. The adjustment slots 4 are matched with the bolts 5. The tops of the four upper steel plates 3 are all fixedly connected with steel pipe threaded sleeves 6. The steel pipe threaded sleeves 6 and the upper steel plates 3 are preferably fixed by welding to improve the stability between the two. Steel pipes 7 are sleeved on the circumferential outer walls of the four steel pipe threaded sleeves 6. Through the arrangement of the steel pipes 7, protection and warning of the light well are realized, and at the same time, it is easy to install and disassemble, can be reused, and improve the use efficiency.

[0023] like Figure 2 As shown, in one embodiment, one side of each of the four lower steel plates 2 is fixedly connected with an elastic anti-skid rubber 8; by providing the elastic anti-skid rubber 8, the lower steel plates 2 are prevented from sliding when being fixed, thereby improving stability.

[0024] like Figure 2 As shown, in one embodiment, the four lower steel plates 2 and the four upper steel plates 3 are all in an "L" shape; through the "L" shape setting, it is convenient to fit the edge of the light well.

[0025] Embodiment 2:

[0026] like Figure 1-2 As shown, in one embodiment, threaded holes are opened on one side of the four upper steel plates 3, and threaded columns 9 are screwed into the four threaded holes. The threaded columns 9 and the extrusion blocks 10 are preferably fixed by welding to improve the structural stability between the two. One end of the four threaded columns 9 is fixedly connected to the extrusion blocks 10, and the other end of the four threaded columns 9 is fixedly connected to the rotating blocks 12. Through the setting of the rotating blocks 12, the threaded columns 9 can be rotated, so that the extrusion blocks 10 allow the upper steel plates 3 to fix the light well.

The upper steel plate 3 and the lower steel plate 2 can adjust the width of the upper steel plate 3 and the lower steel plate 2 by adjusting the slot 4 in multiple gears to make it consistent with the thickness of the conventional flip-up wall. The adjusting slots 4 on the upper steel plate 3 and the lower steel plate 2 are overlapped and fixed by bolts 5. The elastic non-slip rubber 8 on the lower steel plate 2 fits with the flip-up wall, effectively preventing the vertical displacement of the steel plate and providing a certain buffer to protect the wall. Rotating the rotating block 12 drives the threaded column 9 to rotate, driving the extrusion block 10 to fix the wall of the light well. The upper steel plate 3 is provided with a reserved steel pipe threaded sleeve 6, which can be threadedly connected to the steel pipe 7 column guardrail. The four-sided enclosure makes the temporary railing protection stable and reliable, realizes the protection and warning of the light well, and is easy to install and disassemble, can be reused, and improves the use efficiency.
