Description

Technical Field

[0001] This utility model relates to the field of operating platform technology, and in particular to an operating platform on the outside of a parapet wall. Background Technology

[0002] A parapet wall is a low wall around the roof of a building. Its main function, in addition to maintaining safety, is to be finished with waterproof bricks at the bottom to prevent water from seeping into the waterproof layer or rainwater from overflowing from the roof. In order to improve the continuity and integrity of the parapet wall, a coping with a width greater than that of the parapet wall is usually installed at the top of the parapet wall.

[0003] After the parapet wall is built, it needs to be beautified by tiling or sandblasting on its outer side. When constructing the outer side of the parapet wall, a large number of steel pipes and bolts are usually used to build scaffolding on the outer side of the parapet wall, and safety nets are fixed on the outer side of the scaffolding. Construction workers stand on the top of the scaffolding to carry out construction on the outer side of the parapet wall. Since the scaffolding is built with steel pipes and bolts, it is relatively inconvenient to build. The top of the parapet wall is usually fixed with a pressure strip. Since the width of the pressure strip is slightly wider than the parapet wall, when the operating platform 5 is attached to the top of the parapet wall, the rollers 2 installed on the frame 1 cannot contact the outer side of the parapet wall, affecting the stability of the operating platform 5 attached to the top of the parapet wall. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an operating platform on the outside of the parapet wall, which aims to improve the inconvenience of scaffolding construction in the prior art, which is constructed using steel pipes and bolts.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an operating platform on the outer side of the parapet wall, comprising:

[0006] The frame has an integral hanging part at the top, which can be hung on the top of the parapet wall.

[0007] Side panels are respectively installed on one side of the frame, the side wall of the hanging part, and the parapet wall on the top surface of the hanging part. Rollers are rotatably connected to the side of the side panel facing the parapet wall.

[0008] The operating platform is fixedly connected to the frame on the side outside the parapet wall, with a closed bottom structure to provide construction space.

[0009] As a further description of the above technical solution:

[0010] The side panels are fixedly connected to the hanging part and the frame, respectively.

[0011] As a further description of the above technical solution:

[0012] The side plate is connected to the hanging part and the frame respectively by push rods.

[0013] As a further description of the above technical solution:

[0014] It also includes a compression ring, which is fixedly connected to the hanging part and one side of the frame, respectively, and the push rod is inserted into one end of the compression ring and passes through the hanging part and the frame respectively.

[0015] As a further description of the above technical solution:

[0016] It also includes a limiting groove, which is formed on the outside of the push rod, and the limiting groove is set as a semi-circular structure.

[0017] As a further description of the above technical solution:

[0018] The inner wall of the extrusion ring has a cavity, and a limiting plate is fixedly connected to the inner side wall of the cavity 11. A protrusion is provided on one bottom side of the limiting plate, and the bottom of the protrusion is inserted into the limiting groove to fix the push rod.

[0019] As a further description of the above technical solution:

[0020] A sleeve is fitted onto the outer side of the bottom end of the hanging part, and a fixing ring is threaded onto the outer side of the sleeve.

[0025] This utility model has the following beneficial effects:

[0026] In this invention, two push rods on the left and right sides of the rotating frame cause the protrusion to exit the limiting groove and push the limiting plate upward. Then, push the push rod to move the side plate, so that the rollers installed on the frame are in close contact with the side wall of the parapet. Rotate the push rod in the opposite direction to move the limiting groove to below the protrusion on the limiting plate. At this time, the limiting plate will rebound due to its own elasticity, causing the protrusion to enter the limiting groove and fix the fixing rod. The rollers installed on the hanging part are adjusted in the same way to make the connection between the operating platform and the parapet more stable. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figure 1 This utility model provides an embodiment of an operating platform on the outside of a parapet wall, comprising a frame 1. An operating platform 5 is fixedly connected to one side of the frame 1 outside the parapet wall. A hanging part 3 is integrally provided on the top of the frame 1. Side plates 12 are fixedly connected to the side walls of the frame 1, the side walls of the hanging part 3, and the side of the top of the hanging part 3 facing the parapet wall. Rollers 2 are rotatably connected to both ends of the side plates 12 facing the parapet wall. The hanging part 3 is hung against the top of the parapet wall, thereby installing the operating platform 5 on the parapet wall. This allows workers to stand on the operating platform 5 to carry out construction on the outside of the parapet wall. When the operating platform 5 is pushed, the rollers 2 rotate on the surface of the parapet wall, thereby adjusting the position of the operating platform 5 on the outside of the parapet wall.

[0038] The outer side of the operating platform 5 is fixedly equipped with guardrails to protect the staff standing on the operating platform 5.

[0039] Reference Figure 2-7The top of the parapet wall is usually fixed with a pressure strip. Since the width of the pressure strip is slightly wider than the parapet wall, when the operating platform 5 is hung on the top of the parapet wall, the rollers 2 installed on the frame 1 cannot contact the outside of the parapet wall, which affects the stability of the operating platform 5 hanging on the top of the parapet wall. Therefore, it is necessary to adjust the rollers 2 on one side of the frame 1 facing the parapet wall. The specific adjustment structure is as follows: the hanging part 3 and the side plate 12 on the side of the frame 1 facing the parapet wall are connected by a push rod 9. The hanging part 3 and the front and rear sides of the frame 1 are both equipped with push rods 9. One end of the push rod 9 is rotatably connected to one side of the side plate 12.

[0040] In this embodiment, mounting holes are respectively provided on the side of the hanging part 3 and the frame 1 that are in contact with the parapet wall. The push rod 9 is installed in the mounting hole and is connected to the mounting hole by a thread. When the push rod 9 is rotated, the push rod 9 can move in the mounting hole under the action of the thread. When the push rod 9 is not rotated, the push rod 9 remains stationary in the threaded hole.

[0041] After the frame 1 is attached to the parapet wall, rotate the push rod 9 to move it closer to the parapet wall until the hanging part 3 and the roller 2 on one side of the frame 1 can be tightly attached to the inner and outer sides of the parapet wall respectively, so that the roller 2 can contact the parapet wall. For pressure strips of different widths, the position of the roller 2 can be adjusted to ensure that the roller 2 contacts the parapet wall.

[0042] When the operator stands on the operating platform 5, downward pressure is applied to the platform, while a force is also applied towards the parapet wall. This force acts on the push rod 9, causing pressure between the push rod 9 and the threads inside the threaded hole, thus providing better limiting for the push rod 9. The push rod 9 will not easily rotate under no external force.

[0043] In addition to the above-mentioned solutions, the applicant has also designed the following solutions for adjusting push rod 9:

[0044] The hanging part 3 and the frame 1 have mounting holes on the side facing the parapet wall. The push rod 9 is movably installed in the mounting holes. One end of the push rod 9 is sleeved with a compression ring 10. One side of the multiple compression rings 10 is fixedly connected to the side of the hanging part 3 and the frame 1 away from the parapet wall. The inner side of the compression ring 10 has a cavity 11. The inner wall of the cavity 11 is fixedly connected to a limit plate 4. The limit plate 4 is made of elastic material such as spring steel. One end of the limit plate 4 is fixedly connected to a protrusion. The protrusion is set as a semi-circular structure.

[0045] Multiple evenly distributed limiting grooves 6 are provided on the outer side of the push rod 9. The limiting grooves 6 are semi-circular in structure and are opened along the axial direction of the push rod 9. Figure 4 As shown, one end of the protrusion is inserted into the limiting groove 6, as... Figure 5 As shown.

[0046] In the initial state, the protrusion is engaged inside the limiting groove 6. When the position of the roller 2 needs to be adjusted, the push rod 9 installed on the rotating frame 1 causes the protrusion to disengage from the limiting groove 6. Then, pushing the push rod 9 moves the roller 2 closer to the parapet wall until it is flush against the parapet wall. Figure 7 As shown, after the roller 2 on one side of the frame 1 is in close contact with the parapet wall, the push rod 9 is rotated in the opposite direction to make the limiting groove 6 on the push rod 9 rotate to the bottom of the protrusion of the limiting plate 4. The elastic force of the limiting plate 4 itself pushes the protrusion into the limiting groove 6 to fix the push rod 9. Then, the position of the roller 2 installed on the hanging part 3 is adjusted by the same method to make the connection between the operating platform 5 and the parapet wall more stable.

[0047] In this application, a push rod 9 is provided on the frame 1 at the outer edge of the parapet wall. After adjusting the push rod 9, the push rod 9, along with the roller 2, rests against the outer edge of the parapet wall, which makes the frame 1 more stable. Moreover, when the parapet wall strip protrudes outward, the vertical surface of the strip protrudes beyond the plane of the parapet wall. After the push rod 9 and the roller 2 come into contact with the parapet wall, they provide support for the frame 1, which makes the hanging part 3 hang more stably, so as to prevent the top of the frame 1 from tilting outward due to the lack of support at the bottom of the frame 1.

[0048] Sleeves 7 are slidably connected to both outer sides of the bottom left side of frame 1. A fixing ring 8 is installed on the outer side of sleeve 7. The outer side of the top of sleeve 7 has internal and external threads. The inner wall of fixing ring 8 is fitted with internal threads. Fixing ring 8 is connected to the outer side of the top of sleeve 7 through internal and external threads. The inside of fixing ring 8 is set with a conical structure. The outer side of the top of sleeve 7 is set with a conical structure. The top of sleeve 7 has a slot. The material of sleeve 7 is elastic alloy or other elastic material.

[0049] Before hanging the operating platform 5 on the top of the parapet, rotate the fixing ring 8 and pull it upward to remove it from the outside of the sleeve 7. Pull the sleeve 7 downward to make it slide on the outside of the frame 1. Put the fixing ring 8 back on the outside of the sleeve 7 and twist it in the opposite direction. When twisting the fixing ring 8, the fixing ring 8 will gradually move downward. Since the inner side of the fixing ring 8 and the outer side of the sleeve 7 are both conical structures, the top of the sleeve 7 will be squeezed and gradually tightened inward to fix the sleeve 7 during the movement of the fixing ring 8. By adjusting the position of the sleeve 7 outside the hanging part 3, the length of the hanging part 3 is increased, making the connection between the hanging part 3 and the parapet wall more stable.

[0050] When attaching frame 1 to the parapet wall with a top cap, remove the fixing ring 8 from the outside of sleeve 7, then pull sleeve 7, and then put the fixing ring 8 back onto the outside of sleeve 7 and rotate the fixing ring 8 in the opposite direction to fix sleeve 7. By adjusting the position of sleeve 7 on the hanging part 3, the length of the hanging part 3 is increased, making the connection between the hanging part 3 and the parapet wall more stable. Then, hang the operating platform 5 on the top of the parapet wall and rotate the hanging part 3 and the two push rods 9 on the front and rear sides of frame 1. The side wall of the limiting groove 6 is arc-shaped. When the push rod 9 rotates, the protrusion will slide out of the limiting groove 6 and squeeze the limiting plate 4 to deform. Then, the push rod 9 is pushed so that the side plate 12 drives the hanging part 3 and the roller 2 on one side of the frame 1 to approach the parapet wall. When the hanging part 3 and the roller 2 on one side of the frame 1 are in close contact with the side wall of the parapet wall, the push rod 9 is rotated in the opposite direction so that the protrusion on the limiting plate 4 enters the limiting groove 6 again to fix the push rod 9, making the connection between the frame 1 and the parapet wall more stable.
