Detailed implementation manners

[0025] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0026] As Figure 1 shown, a portable and detachable vertical wellhead safety protection device includes a protective fence 1, a sliding rod 2, a clamping rod 3 and a fixator 4.

[0027] As Figure 1 shown, the protective fence 1 is vertically arranged on the ground and covers the position of the vertical wellhead. The sliding rod 2 is horizontally slidably connected to both sides of the protective fence 1, and one end thereof is used to extend into the vertical wellhead. The clamping rod 3 is arranged at the inner end of the sliding rod 2 and is used to press against the inner wall of the concrete building wall at the vertical wellhead position.

[0028] As Figure 1 , Figure 2 shown, the fixator 4 is arranged on the protective fence 1 and is used to fix the sliding rod 2. The fixator 4 includes a fixing block 41 and a wing bolt 42.

[0029] As Figure 1 , Figure 2 shown, a fixing hole 43 for the sliding rod 2 to pass through is vertically penetrated through the fixing block 41, and a tensioning slot 44 communicating with the fixing hole 43 is vertically extended downward from the upper end surface of the fixing block 41. The wing bolt 42 horizontally penetrates through the upper end of the fixing block 41 and is used to control the free tensioning of the tensioning slot 44.

[0030] When installing the protection device, by controlling the sliding of the sliding rod 2 to drive the clamping rod 3 to slide, the clamping rod 3 is clamped on the concrete building wall at the vertical wellhead position, and then the wing bolt 42 is tightened to realize the tightening of the fixing block 41, thereby realizing the clamping of the sliding rod 2 and completing the installation and fixing of the protection device.

[0031] Therefore, by setting the installation protection device with nail-free installation, the protection device can be quickly and conveniently installed by hand at the vertical wellhead position, improving the construction efficiency. At the same time, it can also be quickly disassembled and used for turnover, achieving the effects of simple structure, convenient use, low safety hazards, good protection effect and avoiding waste of labor costs.

[0032] As Figure 1 ,Figure 3 As shown in the figure, the guardrail 1 includes a pair of support columns 11, a plurality of left guardrail pipes 12 and a plurality of right guardrail pipes 13. The pair of support columns 11 are vertically arranged, and the left guardrail pipes 12 and the right guardrail pipes 13 are arranged at intervals and horizontally inside the pair of support columns 11. The left guardrail pipes 12 are inserted and slid on the right guardrail pipes 13, and a compression bolt 14 for pressing the left guardrail pipes 12 is threadedly connected to the right guardrail pipes 13.

[0033] Therefore, during the use of the protection device, by setting the telescopic guardrail 1, the size specification of the guardrail 1 can be freely adjusted according to the size of the shaft opening, so as to adapt to the shaft openings with different requirements and improve the practicability.

[0034] Such as Figure 1 、 Figure 3 As shown in the figure, reinforcing pipes 15 are vertically arranged on the inner sides of the left guardrail pipes 12 and the right guardrail pipes 13 to increase the structural strength and stability of the entire guardrail 1. A footrest 5 is horizontally arranged between the outer side walls at the lower ends of the pair of support columns 11 to prevent items on the ground from rolling into the shaft, thereby realizing the stable protection of the shaft opening.

[0035] Such as Figure 1 、 Figure 4 As shown in the figure, a hook 51 penetrating the footrest 5 is arranged on the support column 11, so as to realize the quick installation and disassembly of the footrest 5 and ensure the stability after installation.

[0036] Such as Figure 1 、 Figure 4 As shown in the figure, the footrest 5 includes a pair of end plates 52 and an intermediate plate 53. Plug rods 54 are arranged at both ends of the intermediate plate 53, and insertion holes 55 for inserting the plug rods 54 are arranged on the end plates 52. Therefore, by setting the assembled footrest 5, an intermediate plate 53 with a suitable length can be selected according to the distance between the support columns 11, and the free switching of the length specification of the footrest 5 can be realized to meet different use requirements.
