Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation technology, specifically to a safety guardrail for high-altitude operations. Background Technology

[0002] Working at height refers to work performed at a height relative to a certain location. Safety railings for working at height are facilities used to protect the safety of workers at height. They are usually installed around floors, roofs, balconies, and other locations with a high risk of falling from height. They can prevent people and objects from falling from heights.

[0003] High-altitude work safety railings typically consist of support posts and multiple crossbars. Some high-altitude work safety railings use a detachable connection between the support posts and crossbars. In the current technology, when workers install the crossbars to the support posts, they need to install multiple crossbars one by one, which makes the installation of high-altitude work safety railings cumbersome and increases the danger of installation. Utility Model Content

[0004] This utility model provides a safety guardrail for high-altitude operations, which can overcome the shortcomings of the existing high-altitude operation guardrails, which are relatively cumbersome to install.

[0005] According to the present invention, a safety guardrail for high-altitude operations includes a device body, the device body includes a support column, a plurality of mounting slots are provided along the height direction at the support column, and a crossbar is provided in each of the plurality of mounting slots; a positioning channel for connecting the plurality of mounting slots is provided along the height direction at the support column, and the plurality of mounting slots and the positioning channel are provided with a positioning rod for positioning the crossbar.

[0006] Compared with existing technologies, workers only need to operate the positioning rod to position multiple crossbars at the same time, reducing the steps required to limit the position of multiple crossbars one by one and improving the efficiency of disassembly and assembly of protective fences.

[0007] Preferably, the mounting groove includes a push-in groove opened horizontally on the outer wall of the support column, and an insertion groove is provided at the bottom of the outer wall of the push-in groove. The crossbar includes an insertion part for sliding inside the push-in groove and the insertion groove.

[0008] In this invention, the insertion part is pushed into the insertion groove through the push-in groove, which can quickly pre-fix the crossbar, thereby facilitating the uniform positioning of the subsequent positioning rod.

[0009] Preferably, a through hole is provided at the top of the outer wall of the insertion part, and the positioning rod is slidably inserted into the through hole.

[0010] In this invention, when the positioning rod is inserted into multiple mounting slots, the positioning rod will be inserted into the through hole, thereby limiting the horizontal insertion part of the multiple crossbars.

[0011] Preferably, multiple positioning blocks are equidistantly arranged on the outer wall of the positioning rod along the height direction, and a passage hole is provided through the inner wall of the through hole for the multiple positioning blocks to pass through.

[0012] In this invention, rotating the positioning rod causes the positioning block to be located at the top of the insertion part and offset from the passage hole, thereby limiting the height of multiple positioning blocks.

[0013] As a preferred option, an expansion channel is provided on the outer wall of the positioning channel to allow multiple positioning blocks to pass through.

[0014] In this invention, the expansion channel can guide the positioning block during the sliding process, allowing it to be smoothly inserted into multiple passage holes, thus improving the ease of installation.

[0015] Preferably, a limiting groove is provided on the top side wall of the positioning channel, and a limiting part is provided on the top of the positioning rod for cooperating with the limiting groove, and a positioning bolt is provided on the top of the limiting part.

[0016] In this invention, the limiting part extends into the limiting groove to limit the rotation direction of the positioning rod, and then the positioning rod is fixed again by the positioning bolt to improve the stability of the positioning rod's limiting.

[0017] Preferably, the crossbar also includes a telescopic support rod fixed to the outer wall of the insertion part and a sleeve main rod slidably disposed on the outer wall of the telescopic support rod.

[0018] In this utility model, the length of the telescopic support rod inside the main sleeve can be adjusted according to the installation requirements, which not only facilitates the installation by the staff, but also adapts to the installation requirements of different lengths. At the same time, the telescopic support rod allows the staff to adjust the length of the crossbar, which is convenient for transportation. Attached Figure Description

[0025] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0026] Example 1

[0027] like Figure 1-4 As shown, this embodiment provides a safety guardrail for high-altitude operations, which includes a device body 100. The device body 100 includes a support column 110. Multiple mounting slots 120 are provided along the height direction at the support column 110. Each of the multiple mounting slots 120 is provided with a horizontal bar 130.

[0028] A positioning channel 410 is provided along the height direction at the support column 110 for connecting multiple mounting slots 120. The multiple mounting slots 120 and the positioning channel 410 are provided together with a positioning rod 210 for positioning the crossbar 130.

[0029] This invention discloses a safety guardrail for high-altitude operations. Multiple horizontal bars 130 are fixed by inserting positioning rods 210 into multiple mounting slots 120. Compared with the prior art, workers only need to operate the positioning rods 210 to position multiple horizontal bars 130 at the same time, reducing the process of limiting multiple horizontal bars 130 one by one and improving the efficiency of disassembly and assembly of the guardrail.

[0030] Combination Figure 2-5 As shown, in this embodiment, the mounting groove 120 includes a push-in groove 510 opened horizontally on the outer wall of the support column 110, and an insertion groove 520 is provided at the bottom of the outer wall of the push-in groove 510. The crossbar 130 includes an insertion part 310 for sliding inside the push-in groove 510 and the insertion groove 520. A through hole 320 is provided through the top of the outer wall of the insertion part 310, and the positioning rod 210 is slidably inserted into the through hole 320.

[0031] With the above structure, when the workers fix multiple crossbars 130, they can push the insertion part 310 into the insertion groove 520 through the push groove 510 to quickly pre-fix the crossbars 130, which facilitates the unified positioning of the positioning rod 210. At the same time, when the positioning rod 210 is inserted into multiple mounting grooves 120, the positioning rod 210 will be inserted into the through hole 320, thereby limiting the horizontal direction of the insertion part 310 of the multiple crossbars 130.

[0032] Combination Figure 2-5As shown, in this embodiment, multiple positioning blocks 330 are equidistantly arranged on the outer wall of the positioning rod 210 along the height direction, and a passage hole 340 is provided through the inner wall of the through hole 320 to allow the multiple positioning blocks 330 to pass through; an expansion channel 530 is provided on the outer wall of the positioning channel 410 to allow the multiple positioning blocks 330 to pass through.

[0033] With the above structure, after the worker inserts the positioning rod 210 into the bottom of the channel formed by the multiple mounting slots 120 and the positioning channel 410 through the passage hole 340, the positioning rod 210 is rotated so that the positioning block 330 is located at the top of the insertion part 310 and is offset from the passage hole 340, thereby limiting the height of the multiple positioning blocks 330; at the same time, when the positioning block 330 slides in the positioning channel 410, the expansion channel 530 allows the positioning block 330 and the positioning rod 210 to slide smoothly in the positioning channel 410, and the expansion channel 530 can guide the positioning block 330 during the sliding process, so that it can be smoothly inserted into the multiple passage holes 340, improving the convenience of installation.

[0034] Combination Figure 4-6 As shown, in this embodiment, a limiting groove 610 is provided on the top side wall of the positioning channel 410, and a limiting part 620 for cooperating with the limiting groove 610 is provided on the top of the positioning rod 210, and a positioning bolt 630 is provided on the top of the limiting part 620.

[0035] With the above structure, the operator can rotate the positioning rod 210 when it is close to the bottom. The limiting part 620 will penetrate into the limiting groove 610, thereby limiting the rotation direction of the positioning rod 210. The positioning rod 210 is then fixed again by the positioning bolt 630, which improves the stability of the positioning rod 210.

[0036] Combination Figure 3-4 As shown, in this embodiment, the crossbar 130 also includes a telescopic support rod 420 fixed to the outer wall of the insertion part 310 and a sleeve main rod 430 slidably disposed on the outer wall of the telescopic support rod 420.

[0037] With the above structure, when installing the crossbar 130, the staff can first fix the support column 110, and then adjust the length of the telescopic support rod 420 inside the main rod 430 according to the installation requirements. This not only facilitates the installation by the staff, but also adapts to different installation requirements. At the same time, the telescopic support rod 420 allows the staff to adjust the length of the crossbar 130, which is convenient for transportation.

[0038] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0039] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
