Abstract
Description
Technical Field
[0001] This utility model relates to the field of foundation pit guardrail technology, specifically to a foundation pit guardrail for water plant construction. Background Technology
[0002] With the development of modern society, construction is becoming more and more frequent. Whether it is new development or the repair of old buildings, guardrails are needed to prevent pedestrians from getting close. Especially during road construction and repair, which is usually done in foundation pits, pedestrians or vehicles traveling at high speeds may fall in if guardrails are not installed. Therefore, guardrails are often required for protection.
[0003] Existing guardrails are mostly installed by using a combination of support posts and fixed frames. There are also connecting ear plates between the support posts and fixed frames. During use, the ear plates are mostly welded to the support posts. In actual use, when it is necessary to surround and block the foundation pit, additional connectors are required at the corners of the fixed frame connection. The additional connectors will separate from the ear plates after disassembly, resulting in the loss of connectors during transportation and handling. Therefore, a foundation pit guardrail for water plant construction is proposed. Utility Model Content

[0028] like Figures 1 to 5As shown, a foundation pit guardrail for water plant construction includes: a fixed frame 1 with multiple pins 101 on the outside; a support member 2, located on the outside of the fixed frame 1, for supporting the fixed frame 1; and an adjustment mechanism, located on the outside of the support member 2, for fixing the fixed frame 1. The adjustment mechanism includes an adjustment member 3 and a control member 4. The adjustment member 3 is located on the outside of the fixed frame 1 for installing the fixed frame 1, and the control member 4 is located on the outside of the adjustment member 3 for fixing the angle of the adjustment member 3. The adjustment member 3, in conjunction with the control member 4, adjusts the fixed frame 1 to different installation angles. Specifically, when the foundation pit needs protection, the fixed frame 1 is supported by the cooperation of the fixed frame 1 and the support member 2. During the process of the fixed frame 1 protecting the foundation pit, the placement angle of the fixed frame 1 is adjusted by the cooperation of the control member 4 and the adjustment member 3, so that the fixed frame 1 can be placed according to the shape of the foundation pit during use. The fixed frame 1 has a fixing strip inside, which can be connected to the fixed frame 1 by a buckle or bolt, facilitating individual replacement of the fixing strip after damage.
[0029] like Figures 1 to 5 As shown, the support member 2 includes a support base 201, and a connecting shaft 202 is provided on the outside of the support base 201. A sliding groove 203 is provided at one end of the connecting shaft 202. Specifically, the support base 201, in conjunction with the connecting shaft 202, provides support for the adjusting member 3 and the fixed frame 1 during use, ensuring the stability of the fixed frame 1 during use.
[0030] like Figures 1 to 5 As shown, the adjusting component 3 includes a first connecting sleeve 301, which is sleeved on the outside of the connecting shaft 202. A second connecting sleeve 302 is sleeved on the outside of the first connecting sleeve 301. Multiple rotating grooves 304 are formed on the outside of the second connecting sleeve 302, and each rotating groove 304 has a connecting block inside. The connecting block is connected to the first connecting sleeve 301. A first fixing sleeve 303 and a second fixing sleeve 305 are respectively provided on the outside of the connecting block and the second connecting sleeve 302. Specifically, the first connecting sleeve 301 and the second connecting sleeve 302 can rotate independently relative to the connecting shaft 202 during use. The independently rotating first... A connecting sleeve 301 and a second connecting sleeve 302, together with a first fixing sleeve 303 and a second fixing sleeve 305, adjust the placement angle of the fixing frame 1 so that the fixing frame 1 can be adjusted according to the shape of the foundation pit. The first fixing sleeve 303 and the second fixing sleeve 305 are both provided with mounting holes. The number of the first fixing sleeve 303 and the second fixing sleeve 305 is selected according to the height of the fixing frame 1, thereby ensuring the stability of the fixing frame 1 during use. When installing the fixing frame 1, the fixing frame 1 is connected by the cooperation of the pin 101 and the mounting hole to ensure the stability of the fixing frame 1 during use.
[0031] like Figures 1 to 5As shown, the control component 4 includes a connecting cover 401, which is open at one end. A rotating ring 403 is provided at the open end of the connecting cover 401, and the rotating ring 403 is connected to the second connecting sleeve 302. A threaded rod 406 is provided inside the connecting cover 401, and one end of the threaded rod 406 is connected to the connecting shaft 202. A connecting plate 405 is provided outside the threaded rod 406, and the connecting plate 405 slides inside the sliding groove 203. A sliding ring 402 and a limiting post 404 are sequentially provided outside the connecting plate 405. The rotating ring 403 is internally provided with… A fixed ring 407 is provided, and the fixed ring 407 is connected to the first connecting sleeve 301. Multiple second limiting grooves 410 and first limiting grooves 409 are respectively provided on the inner wall of the rotating ring 403 and the outer wall of the fixed ring 407. A limiting post 404 is adapted to the second limiting grooves 410 and the first limiting grooves 409. The length of the first limiting groove 409 is greater than that of the second limiting groove 410. Specifically, when it is necessary to adjust the placement angle of the fixed frame 1, the connecting plate 405 and the sliding ring 402 are first moved by the threaded rod 406. During the movement of the sliding ring 402 and the connecting plate 405, the limiting post 404 slides inside the first limiting groove 409 and the second limiting groove 410. Since the length of the first limiting groove 409 is greater than that of the second limiting groove 410, the limiting post 404 can sequentially limit the second connecting sleeve 302 and the first connecting sleeve 301 during the movement of the limiting post 404. This prevents the second connecting sleeve 302 and the first connecting sleeve 301 from rotating synchronously during angle adjustment, ensuring the accurate adjustment of the angle of the first fixing sleeve 303 and the second fixing sleeve 305. The threaded rod 406 is connected to the connecting plate 405 by a thread. The sliding groove 203 can guide the moving connecting plate 405 during use, ensuring that the connecting plate 405 can stably drive the sliding ring 402 and the limiting post 404 to move in position. The rotating ring 403, the fixed ring 407 can be connected to the second connecting sleeve 302 and the first connecting sleeve 301 by a snap or bolt. The rotating ring 403 and the fixed ring 407 can drive the second connecting sleeve 302 and the first connecting sleeve 301 to rotate synchronously, respectively.
[0032] like Figures 1 to 5 As shown, a control block is provided on the outside of the threaded rod 406, and the control block is connected to the connecting cover 401. Specifically, the control block can be in the shape of a block that is easy to hold or can be connected to a wrench, so that the threaded rod 406 can be controlled through the control block during use.
[0033] like Figures 1 to 5As shown, the fixing ring 407 also has a groove 408 at the end relative to the connecting plate 405. Specifically, during the process of the limiting post 404 releasing the limiting of the first connecting sleeve 301 and the second connecting sleeve 302, the groove 408 separates the limiting post 404 from the fixing ring 407, avoiding friction between the limiting post 404 and the fixing ring 407, and making it easier for the operator to control the rotation of the first connecting sleeve 301.
