Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to a reversible protective railing for a building construction machine. Background Technology

[0002] The building construction machine is equipped with an internal operating platform, and protective railings need to be installed on both sides of the walkway of the internal platform to prevent people from falling.

[0003] Most existing guardrails are fixed, integrated structures. While they provide protection, they can hinder the movement of construction workers and materials, as well as impact work below them, reducing efficiency and posing safety hazards. Utility Model Content

[0004] To address the technical problems in the prior art, this utility model provides a reversible protective railing for a building construction machine, comprising a first fixed railing, a second fixed railing, and a retractable railing. The ends of the first and second fixed railings that are far apart from each other are fixed to the suspension pillars of the suspension platform by bolts. The retractable railing is rotatably installed between the first and second fixed railings. The ends of the first and second fixed railings that are close to each other are provided with U-shaped grooves. One end of the retractable railing is installed in the U-shaped groove and is rotatably connected to the first fixed railing by a screw. The other end of the retractable railing is connected to or separated from another U-shaped groove around the rotation point.

[0005] Furthermore, the second fixed railing is provided with a limiting plate, which is located at the bottom of the U-shaped groove.

[0006] Furthermore, both the first fixed railing and the second fixed railing are made of 40*80*3 square steel tubing, while the opening and closing railing is made of 30*60*3 square steel tubing.

[0007] Furthermore, the opening and closing railing has a through slotted hole at one end near the first fixed railing, and the screw is slidably installed in the slotted hole. When the screw is located at the end of the slotted hole far away from the end of the opening and closing railing, the opening and closing railing is vertically set.

[0008] Furthermore, the opening and closing railing is provided with a T-shaped sliding groove, and a T-shaped counterweight is slidably disposed within the T-shaped sliding groove.

[0009] Furthermore, the T-shaped counterweight is provided with a connecting rope, the other end of which extends out of the opening and closing railing from the end away from the strip hole.

[0010] Furthermore, the length of the opening and closing railing is 70cm to 140cm.

[0011] Beneficial effects:

[0012] 1. In this utility model, the arrangement of the first fixed railing, the second fixed railing, the opening and closing railing, the U-shaped groove, and the screw rod serves two purposes: firstly, it provides protection; secondly, it facilitates opening and closing, allowing construction personnel and materials to enter and exit easily, thus improving construction efficiency. It also facilitates construction work under the guardrail, effectively preventing collisions between construction personnel and the guardrail. Specifically, when construction personnel need to work under or pass under the guardrail, they can rotate and lift one end of the opening and closing railing. After the work is completed or the passage is completed, the opening and closing railing can be lowered.

[0013] 2. In this utility model, the limiting plate can limit the opening and closing railing, preventing it from separating from the U-shaped groove on the second fixed railing under gravity. The use of 40*80*3 square steel tubes for the first and second fixed railings and 30*60*3 square steel tubes for the opening and closing railing facilitates the connection and cooperation between the three components, and also makes it easy to obtain materials on site.

[0014] 3. In this utility model, the setting of the strip hole facilitates the sliding of the screw, thereby facilitating the movement of the rotation point of the opening and closing railing and the first fixed railing. On the one hand, it makes it easier to rotate and lift the opening and closing railing, and on the other hand, it can also fix the opening and closing railing, ensuring that the construction personnel do not need to hold it during construction. At the same time, it can also effectively prevent the opening and closing railing from falling freely, thus improving safety performance.

[0015] 4. In this utility model, the T-shaped groove and T-shaped counterweight can change the center of gravity of the opening and closing railing, saving the external force required to lift or lower it; the connecting rope can make it easy for construction personnel to control the T-shaped counterweight to slide towards the end away from the strip hole, which facilitates the connection between the opening and closing railing and the second fixed railing.

[0028] This utility model provides a reversible protective railing for a building construction machine, such as... Figure 1 and Figure 2 As shown, the system includes a first fixed railing 1, a second fixed railing 2, and a hinged railing 3. The ends of the first fixed railing 1 and the second fixed railing 2 that are far apart from each other are fixed to the suspension posts 4 of the suspended platform by bolts. The hinged railing 3 is rotatably installed between the first fixed railing 1 and the second fixed railing 2. The distance between the first fixed railing 1 and the second fixed railing 2 is 80cm to 150cm. The length of the hinged railing 3 is 70cm to 140cm to ensure sufficient passage space. The ends of the first fixed railing 1 and the second fixed railing 2 that are close to each other are provided with U-shaped grooves. One end of the hinged railing 3 is installed in the U-shaped groove 5 and is rotatably connected to the first fixed railing 1 by a screw 6 in the up-down direction. The other end of the hinged railing 3 is connected to or separated from another U-shaped groove 5 around the rotation point.

[0029] In this embodiment, the arrangement of the first fixed railing 1, the second fixed railing 2, the opening and closing railing 3, the U-shaped groove 5, and the screw 6 serves two purposes: firstly, it provides protection; secondly, it facilitates opening and closing, allowing construction personnel and materials to enter and exit easily, thus improving construction efficiency. It also facilitates construction work under the guardrail, effectively preventing collisions between construction personnel and the guardrail. Specifically, when construction personnel need to work under or pass under the guardrail, they rotate and lift one end of the opening and closing railing 3. After completing the work or passing through, they lower the opening and closing railing 3.

[0030] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the second fixed railing 2 is provided with a limiting plate 7, which is located at the bottom of the U-shaped groove 5.

[0031] In this embodiment, the limiting plate 7 can limit the opening and closing railing 3, preventing the opening and closing railing 3 from separating from the U-shaped groove 5 on the second fixed railing 2 under the action of gravity. Specifically, when the opening and closing railing 3 is lowered and cooperates with the second fixed railing 2, it will fall on the limiting plate 7.

[0032] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the first fixed railing 1 and the second fixed railing 2 are both 40*80*3 square steel tubes, and the opening and closing railing 3 is a 30*60*3 square steel tube.

[0033] In this embodiment, by setting the first fixed railing 1 and the second fixed railing 2 to be 40*80*3 square steel tubes and the opening and closing railing 3 to be 30*60*3 square steel tubes, the connection and cooperation between the three can be facilitated, and the materials can be easily obtained on site.

[0034] In this utility model, preferably, such as Figure 2 and Figure 3 As shown, the opening and closing railing 3 has a through strip hole 8 at one end near the first fixed railing 1. The screw 6 is slidably installed in the strip hole 8. When the screw 6 is located at the end of the strip hole 8 far away from the end of the opening and closing railing 3, the opening and closing railing 3 is vertically set.

[0035] In this embodiment, the setting of the strip hole 8 facilitates the sliding of the screw 6, thereby facilitating the movement of the rotation point between the opening and closing railing 3 and the first fixed railing 1. On the one hand, it makes it easier to rotate and lift the opening and closing railing 3, and on the other hand, it can also fix the opening and closing railing 3, ensuring that the construction personnel do not need to hold it during construction, and at the same time, it can effectively prevent the opening and closing railing 3 from falling freely, thus improving safety performance.

[0036] In this utility model, preferably, such as Figure 2 and Figure 3 As shown, the opening and closing railing 3 is provided with a T-shaped sliding groove 9, and a T-shaped counterweight 10 is slidably disposed in the T-shaped sliding groove 9; a connecting rope 11 is provided on the T-shaped counterweight 10, and the other end of the connecting rope 11 extends out of the opening and closing railing 3 from the end of the opening and closing railing 3 away from the strip hole 8.

[0037] In this embodiment, by setting the T-shaped slide 9 and the T-shaped counterweight 10, the center of gravity of the opening and closing railing 3 can be changed, saving the external force required when lifting or lowering, and at the same time increasing the lifting or lowering speed; by setting the connecting rope 11, the construction personnel can easily control the T-shaped counterweight 10 to slide towards the end away from the strip hole 8, which facilitates the connection between the opening and closing railing 3 and the second fixed railing 2.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
