Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically to a mobile guardrail for engineering construction. Background Technology

[0002] Protective fences are usually required around urban municipal construction sites and some dangerous municipal facilities. These fences serve to isolate the site, enhance construction safety and the safety of on-site facilities, and prevent unauthorized personnel from entering.

[0003] In practice, existing guardrails typically use multiple guardrails to enclose the construction area, and these guardrails are connected together by wires or ropes. After construction is completed, the wires or ropes are dismantled, which is relatively troublesome. This method of enclosure is acceptable if the construction period is long; however, it will affect efficiency if the construction period is short or it is only temporary.

[0004] To address these shortcomings, a mobile protective barrier for engineering construction is proposed, which upgrades and modifies the existing device. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile protective fence for engineering construction in order to solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A mobile protective fence for engineering construction includes an outer shell. A folding protective fence is rotatably connected to one side of the inner wall of the outer shell. A baffle is rotatably connected to the end of the folding protective fence away from the outer shell. Multiple self-locking casters are fixedly installed at equal intervals at the bottom of the folding protective fence. A second self-locking caster is fixedly installed at the bottom of the baffle. A handle is fixedly installed on the upper side of the outer end of the baffle. A fixing mechanism is provided inside the outer shell. A sliding rod is slidably connected to the upper side of the baffle away from the folding protective fence. An anti-slip groove is formed on the upper surface of the sliding rod. A transmission rod is slidably connected to the bottom of the sliding rod. The outer end of the transmission rod is slidably connected to the inner wall of the baffle. A conical block is fixedly connected to the lower end of the transmission rod extending out of the baffle. A stop block is fixedly connected to the upper end of the transmission rod. A sliding groove is formed on the inner wall of the sliding rod for the outer end of the stop block to slide.

[0008] Furthermore, a handle is fixedly connected to the upper left side of the outer casing, and rotating wheels are rotatably connected to both sides of the bottom of the outer casing.

[0009] Furthermore, a groove is provided on the upper side of the end of the baffle away from the folding guardrail for the outer end of the sliding rod to slide and connect.

[0010] Furthermore, the fixing mechanism includes a motor, the motor is fixedly installed on the inner wall of the housing, a threaded rod is fixedly installed on the output shaft of the motor, the outer side of the threaded rod near the motor is rotatably connected to the inner wall of the housing through a bearing, a support rod is threadedly connected to the lower side of the outer end of the threaded rod, and an anti-slip block is fixedly installed on the lower end of the support rod extending out of the housing.

[0011] Furthermore, a guide block is fixedly connected to the upper side of the outer end of the support rod, and a guide groove is provided on the inner wall of the outer shell for the outer end of the guide block to slide.

[0026] like Figures 1 to 5As shown, a mobile protective fence for engineering construction includes a shell 1. A folding protective fence 16 is rotatably connected to one side of the inner wall of the shell 1. A baffle 14 is rotatably connected to the end of the folding protective fence 16 away from the shell 1. Multiple self-locking casters 17 are fixedly installed at equal intervals at the bottom of the folding protective fence 16. A second self-locking caster 15 is fixedly installed at the bottom of the baffle 14. A handle 13 is fixedly installed on the upper side of the outer end of the baffle 14. A fixing mechanism 2 is provided inside the shell 1. A sliding rod 182 is slidably connected to the upper side of the baffle 14 away from the folding protective fence 16. An anti-slip groove 181 is formed on the upper surface of the sliding rod 182. A transmission rod 184 is slidably connected to the bottom of the sliding rod 182. The outer end of the transmission rod 184 is connected to the baffle. The inner wall of the baffle 14 is slidably connected. The lower end of the transmission rod 184 extends out of the baffle 14 and is fixedly connected to a conical block 18. The upper end of the transmission rod 184 is fixedly connected to a stop block 185. The inner wall of the sliding rod 182 is provided with a sliding groove 186 for the outer end of the stop block 185 to slide. Specifically, by pulling the handle 13 outward, the baffle 14 drives the folding guardrail 16 to move, so that the folding guardrail 16 is unfolded. The unfolded folding guardrail 16 is stabilized by the self-locking caster 17. The sliding rod 182 is pushed outward by the anti-slip groove 181 and the sliding rod 182 is moved downward, so that the transmission rod 184 inserts the conical block 18 into the ground, fixes the baffle 14, and improves the stability of the guardrail.

[0027] like Figure 1 and Figure 2 As shown, a handle 10 is fixedly connected to the upper left side of the outer casing 1, and rotating wheels 12 are rotatably connected to both sides of the bottom of the outer casing 1; specifically, this facilitates the movement of the pushing device.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the upper side of the baffle 14 away from the folding guardrail 16 is provided with a sliding groove 183 for the outer end of the sliding rod 182 to slide and connect; specifically, to facilitate the downward movement of the sliding rod 182.

[0029] like Figure 1 and Figure 5 As shown, the fixing mechanism 2 includes a motor 24. The motor 24 is fixedly installed on the inner wall of the housing 1. A threaded rod 25 is fixedly installed on the output shaft of the motor 24. The outer side of the threaded rod 25 near the motor 24 is rotatably connected to the inner wall of the housing 1 through a bearing. A support rod 21 is threadedly connected to the lower side of the outer end of the threaded rod 25. The lower end of the support rod 21 extends out of the housing 1 and is fixedly installed with an anti-slip block 22. A control button 11 is fixedly installed on the upper side of the outer end of the housing 1. Specifically, the motor 24 is started by the control button 11 to drive the threaded rod 25 to rotate, so that the support rod 21 drives the anti-slip block 22 to contact the ground, thereby increasing the stability of the device on the ground.

[0030] like Figure 1 and Figure 5 As shown, a guide block 26 is fixedly connected to the upper side of the outer end of the support rod 21, and a guide groove 23 is provided on the inner wall of the outer shell 1 for the outer end of the guide block 26 to slide; specifically, this facilitates the stable movement of the support rod 21.

[0031] In summary: When protective barriers are needed at the construction site, the outer casing 1 is moved to a suitable position by using handle 10. By pulling handle 13 outward, the baffle 14 moves the folding protective barrier 16, causing it to unfold. The unfolded folding protective barrier 16 is stabilized by the self-locking caster 17. The sliding rod 182 is pushed outward by the anti-slip groove 181 and moved downward, causing the transmission rod 184 to insert the cone block 18 into the ground, fixing the baffle 14. The motor 24 is started by the control button 11, which drives the threaded rod 25 to rotate, causing the support rod 21 to drive the anti-slip block 22 to contact the ground, thus stabilizing the entire protective barrier.

[0032] Conversely, it allows the folding guardrail 16 to be easily retracted into the housing 1, and the baffle 14 to be connected to the housing 1, making it easy to quickly store the guardrail and use it conveniently.
