Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, and particularly relates to a guardrail for an underground sump. Background Art

[0002] At present, during underground operations, due to the underground working environment, there is a lot of groundwater in the well. In order to facilitate work in the shaft, a sump is usually dug near the shaft to collect groundwater.

[0003] The sump is generally located beside the shaft. Underground workers walk and work in the shaft for a long time. To prevent workers from accidentally falling into the water and causing safety accidents, a guardrail is usually installed outside the sump to prevent such situations. However, the existing guardrails are basically integrally welded. Since the sizes and shapes of each sump are different, in order to replace the guardrail for the sump, customization is required or multiple guardrails need to be stacked and combined for use, which brings inconvenience to the work of protecting the sump. Therefore, we propose a guardrail for an underground sump, which can be adjusted according to the size and shape of the sump, and can improve the protection ability. Content of the Utility Model

[0004] The utility model provides a guardrail for an underground sump to solve the problems raised in the background art.

[0005] To solve the above problems, the utility model provides a guardrail for an underground sump, including a first guardrail. A second guardrail is hinged to each of the left and right sides of the first guardrail. The first guardrail is composed of a first support column, a second support column, and a number of telescopic rods equidistantly fixed between the first support column and the second support column. The second guardrail is composed of a third support column, a fourth support column, and a number of telescopic rods fixed between the third support column and the fourth support column. Two symmetric hinge seats are fixedly arranged on the outer sides of the first support column and the second support column. A hinge piece matching the hinge seat is fixedly arranged on one side of the third support column, and the hinge piece is rotatably connected to the hinge seat through a rotating shaft.

[0006] Preferably, a fixing seat is rotatably arranged at the bottom end of each of the first support column, the second support column, and the fourth support column, and two rivets are symmetrically threadedly connected in the fixing seat.

[0007] Preferably, the telescopic rod is composed of a sleeve and a support rod, and the support rod is slidably connected in the sleeve. A slide rod is fixedly arranged in the sleeve, and a through hole matching the slide rod is arranged in the support rod. The slide rod is slidably connected in the through hole.

[0008] Preferably, the hinge piece fixedly arranged on the outer side of the third support column is perpendicular to the telescopic rod in the second guardrail.

[0009] The beneficial effects of adopting the above technical solutions are as follows:

[0010] 1. The hinges of the first protective fence and the second protective fence can adjust the angles of the second protective fence on both sides of the first protective fence. By setting the first telescopic rod and the second telescopic rod, the lengths of the first protective fence and the second protective fence can be adjusted, so as to facilitate adjustment according to the size and shape of the sump, and improve the protection performance.

[0011] 2. Through the setting of two rivets in the fixing seat, the first protective fence and the second protective fence can be firmly positioned in the shaft floor, improving the stability of the protection.

[0012] 3. Through the cooperation of the sliding rod in the pipe sleeve and the through hole opened in the support rod, the stability of the telescopic rod is increased, and the protection ability is improved.

[0013] 4. Since the hinge piece is vertically fixed on the outside of the third support column with the telescopic rod, the second protective fence can be folded to be parallel to the first protective fence, so as to facilitate the folding and collection of the first protective fence and the second protective fence, and facilitate handling.
