Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to an adjustable hanging fence safety operation platform. Background Technology

[0002] The high-speed railway suspended fence is an auxiliary structure of the pier, with two main purposes: 1. Safety protection, preventing workers from falling while working on top of the pier and ensuring their safety; 2. Facilitating construction, providing a relatively safe and stable operating space for workers during operations such as bridge maintenance and equipment installation. However, because the suspended fence is located at the top of the pier, there are significant risks associated with working at height during construction.

[0003] In traditional construction, suspended scaffolding installation is carried out using cranes, elevators, or pier-top suspended scaffolding. Using cranes and elevators requires specific site conditions and necessitates frequent changes in work position and frequent deployment and removal of cranes and elevators, resulting in low construction efficiency. When using pier-top suspended scaffolding, the overall system is complex, and the requirements for the balance and vertical force of the tooling are extremely high, leading to significant construction safety risks and poor applicability.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example

[0038] Please refer to the reference. Figures 1 to 4 This embodiment provides an adjustable suspended fence safety work platform, including a work platform 1, an adjustable suspension rod 2, and a top truss 3; the work platform 1 includes a platform steel plate 110 and a platform fence 120, the bottom of the platform fence 120 being connected to the edge of the platform steel plate 110; the adjustable suspension rod 2 includes a channel steel 210, an I-beam 220, and an adjusting bolt 230, the I-beam 220 being movably disposed within the channel steel 210; the channel steel 210 and the I-beam 220 are respectively provided with adjusting screw holes, and are connected by adjusting bolts 230 disposed within the adjusting screw holes; the bottom of the adjustable suspension rod 2 is connected to the platform fence 120; the top truss 3 is connected to the top of the adjustable suspension rod 2.

[0039] In this embodiment, the adjustable suspended safety work platform features an I-beam 220 movably mounted within the channel steel 210. The height of the adjustable boom 2 can be adjusted by moving the I-beam 220 up and down, allowing for vertical adjustment of the work platform 1 to match the height of the pier. Tightening the adjusting bolts 230 secures the boom 2 and the work platform 1. The top truss 3 is integrated with the adjustable boom 2 and the work platform 1. When the work platform 1 is positioned on top of the pier, the top truss 3 contacts the pier, supporting the weight of the work platform 1 and ensuring its stability at the preset height on the pier. This design facilitates movement and work on the platform steel plate 110, while the platform railing 120 provides protection for the workers.

[0040] Among them, the up and down directions refer to... Figures 1 to 5 The up and down directions in the middle.

[0041] Please refer to the reference. Figure 1 , Figure 4 and Figure 5Specifically, the channel steel 210 is set as a pair, and the openings of the two channel steel 210 are arranged opposite each other; the two side flanges of the I-beam 220 are respectively set in the pair of channel steel 210.

[0042] By symmetrically arranging the channel steels 210 in pairs, the I-beams 220 can be stably and movably and adjustablely installed within the pair of channel steels 210 with their openings facing each other.

[0043] Among them, left and right directions respectively refer to Figure 1 , Figure 4 and Figure 5 left and right direction in center.

[0044] Please refer to the reference. Figures 1 to 3 Specifically, the work platform 1 is configured as a rectangular ring structure; the adjustable rods 2 are configured as at least one pair, each pair of adjustable rods 2 is symmetrically arranged, and the top of each pair of adjustable rods 2 is connected to both ends of a top truss 3.

[0045] The rectangular ring-shaped work platform 1 can form a ring-shaped passage around the outside of the pier, which facilitates the movement of construction personnel on the work platform 1 to various installation points; so that the installation of the hanging fence of a pier only requires moving the hanging fence safety work platform once.

[0046] The adjustable rods 2 are arranged in pairs and symmetrically, which facilitates the connection of the top of each pair of adjustable rods 2 to the front and rear ends of a top truss 3, and the connection of the bottom of each pair of adjustable rods 2 to the working platform 1, thereby ensuring the overall balance and stability of the suspended fence safety working platform.

[0047] Among them, each pair of adjustable rods 2 is arranged symmetrically front and back, with the front and back directions respectively pointing to Figure 2 The right and left directions in the middle.

[0048] Please refer to the reference. Figure 1 , Figure 3 , Figure 5 and Figure 6 Specifically, the platform steel plate 110 includes two right-angle bent C-shaped steel plates 111, and the platform fence 120 includes two right-angle bent C-shaped fences 115; the bottom of the two C-shaped fences 115 are respectively connected to the edge of the two C-shaped steel plates 111 to form two C-shaped platforms.

[0049] Please refer to the reference. Figure 2 and Figure 3 The openings of two C-shaped platforms are arranged opposite each other and connected to form a rectangular ring structure working platform 1; each C-shaped platform is connected to at least one pair of adjustable rods 2, and the bottom of each pair of adjustable rods 2 is connected to the side edges of the openings of the C-shaped platform respectively.

[0050] By arranging two C-shaped platforms side by side with their openings facing each other and connecting the openings of the two C-shaped platforms to form a split-structure work platform 1, the length of the work platform 1 can be easily adjusted. For example, the overall length of the work platform 1 can be adjusted by adjusting the distance between the two C-shaped platforms and connecting the two C-shaped platforms with a connector of appropriate length.

[0051] The work platform 1 is formed by combining and connecting two separate C-shaped platforms, making it easier to install. Installation can be achieved through the following steps:

[0052] Step S1: Adjust the height of the adjustable boom 2 according to the height of the pier column, and fix the height of the adjustable boom 2 and the height position of the working platform 1 by adjusting bolt 230;

[0053] Step S2: Use lifting machinery to hoist the two split C-shaped platforms to the top of the pier, so that the top truss 3 of both C-shaped platforms are in contact with the top of the pier, so that the top truss 3 bears the weight of the working platform 1 and supports the working platform 1.

[0054] Step S3: After hoisting the two separate C-shaped platforms to the top of the pier, the construction personnel can be sent to the top of the pier by a lift. Then, the two separate C-shaped platforms are connected to form the overall structure of the work platform 1, ensuring the stability and firmness of the work platform 1.

[0055] Since the C-type platform is connected to at least one pair of symmetrically arranged adjustable rods 2 on the sides of the opening, the C-type platform is connected to at least one top truss 3 through the at least one pair of symmetrically arranged adjustable rods 2. This allows each C-type platform to be supported on the top of the pier through its respective top truss 3, thereby improving the overall stability of the combined suspended fence safety operation platform.

[0056] Please refer to the reference. Figure 1 , Figures 4 to 6 Specifically, each C-shaped platform is connected to two pairs of adjustable rods 2, and the four pairs of adjustable rods 2 are arranged symmetrically from the inside to the outside; the open ends of the two C-shaped platforms are connected by a combination of connecting angle steel 113 and connecting bolts 114.

[0057] On the work platform 1, which consists of two C-shaped platforms, four adjustable booms 2 are arranged from left to right on the same side of the opening of the C-shaped platform. The two adjustable booms 2 on the inner side are arranged symmetrically, and the two adjustable booms 2 on the outer side are also arranged symmetrically.

[0058] Each C-shaped platform is connected to two top trusses 3 via two pairs of adjustable booms 2. When installing the work platform 1, with two support beams placed on top of the pier, in step S2, the two top trusses 3 of each of the two C-shaped platforms can be placed on either side of the two support beams. Furthermore, of the four pairs of adjustable booms 2 and four top trusses 3 of the work platform 1 as a whole, the inner two pairs of adjustable booms 2 and two top trusses 3 are symmetrically arranged, and the outer two pairs of adjustable booms 2 and two top trusses 3 are also symmetrically arranged, thus further ensuring that each C-shaped platform is supported in a balanced and stable manner. In step S3, the open ends of the two separate C-shaped platforms can be connected to each other using two connecting angle steels 113 and connecting bolts 114, thereby forming an integrated suspended fence safety work platform.

[0059] Please refer to the reference. Figure 1 , Figure 2 and Figure 4 , Figure 5 Specifically, the channel steel 210 includes a lower channel steel 211 and an upper channel steel 212, the adjusting screw hole includes a lower adjusting screw hole and an upper adjusting screw hole, and the adjusting bolt 230 includes a lower adjusting bolt 231 and an upper adjusting bolt 232.

[0060] The lower and upper parts of the I-beam 220 are respectively movably disposed within the lower channel steel 211 and the upper channel steel 212; the lower channel steel 211 and the lower part of the I-beam 220 are respectively provided with lower adjusting screw holes and are connected by lower adjusting bolts 231 provided in the lower adjusting screw holes; the upper channel steel 212 and the upper part of the I-beam 220 are respectively provided with lower adjusting screw holes and are connected by upper adjusting bolts 232 provided in the upper adjusting screw holes.

[0061] The bottom of the lower channel steel 211 is connected to the bottom of the platform fence 120, and the top of the upper channel steel 212 is connected to the top truss 3.

[0062] The adjustable hanging fence safety work platform of this embodiment uses an adjustable hanging rod 2 with an upper and lower adjustable structure formed by matching the lower channel steel 211 and the upper channel steel 212 to the lower and upper parts of the I-beam 220, respectively. This expands the height adjustment range of the adjustable hanging rod 2 and the work platform 1, making it more suitable for piers of various sizes and structural forms. The bottom of the lower channel steel 211 can be welded to the bottom of the platform fence 120.

[0063] Please refer to the reference. Figure 1 and Figure 5 An inclined bracing angle steel 112 can be connected between the lower part of the adjusting rod 2 and the working platform 1 to facilitate the concentrated transmission of the forces on the suspended fence safety working platform in multiple directions to the side and top of the pier, thereby improving balance and stability.

[0064] Specifically, the lower channel steel 211 and the C-shaped steel plate 111 are connected by diagonal bracing angle steel 112, and the two diagonal bracing angle steels 112 on the same side of the opening of each C-shaped steel plate 111 are inclined outward from top to bottom.

[0065] By welding an outward-sloping angle steel 112 to the lower channel steel 211 of the two pairs of adjustable rods 2 of each C-shaped platform, the two angle steels 112 of each C-shaped platform are arranged in a figure-eight shape; thereby improving the connection between the lower part of the adjustable rod 2 and the C-shaped platform, which helps to ensure the overall stability of the suspended fence safety operation platform.

[0066] Specifically, the bottom of the lower channel steel 211 is connected to the C-shaped steel plate 111, thereby improving the connection strength between the adjustable rod 2 and the C-shaped platform.

[0067] Please refer to the reference. Figures 1 to 3 , Figure 5 Specifically, a toe board 123 is installed at the bottom of the platform fence 120; a supporting channel steel 310 is installed at the bottom of the top truss 3.

[0068] The toe board 123 connected to the bottom of the platform fence 120 can prevent construction workers from accidentally slipping off the work platform 1, thus improving safety. The supporting channel steel 310 is welded to the bottom of the top truss 3, which can serve as a support between the top truss 3 and the pier column.

[0069] Specifically, such as Figure 6 As shown, the upper surface of the platform steel plate 110 is provided with anti-slip patterns;

[0070] Please refer to the reference. Figures 1 to 3 , Figure 5 The platform fence 120 is composed of at least two transverse flat steel bars 121 and at least two longitudinal fence angle steel bars 122 connected perpendicularly to form a fence structure.

[0071] like Figure 2 As shown, the top truss 3 is set as an isosceles triangle.

[0072] like Figure 6 As shown, the platform steel plate 110 can be made of patterned steel plate using existing technology. That is, the C-shaped steel plate 111 can be made of patterned steel plate.

[0073] Flat steel rods 121 and fence angle steel 122 are welded horizontally and vertically to form a grid-like platform fence 120, which can improve the sturdiness and protection of the platform fence 120.

[0074] The isosceles triangle at the top truss 3 enhances its robustness and stability.

[0075] The adjustable suspended fence safety work platform of this embodiment can also be specifically, such as... Figure 6As shown, triangular connecting ribs 116 are connected to the two bending points of the C-shaped steel plate 111 to reinforce the C-shaped steel plate 111. The connecting ribs 116 are welded to the C-shaped steel plate 111, and the two are located in the same horizontal plane. The connecting ribs 116 can also be made of checkered steel plate.

[0076] Please refer to the reference. Figure 1 , Figure 3 , Figure 5 and Figure 6 The two C-shaped platforms are connected by connecting angle steel 113 and connecting bolts 114 at their respective open ends to form a rectangular ring structure of the working platform 1.

[0077] Please refer to the reference. Figure 1 and Figure 5 Each C-shaped platform is connected to at least one pair of adjustable booms 2, with the two adjustable booms 2 in each pair symmetrically arranged on both sides of the opening of the C-shaped platform.

[0078] Each C-shaped platform can be connected to two pairs of adjustable rods 2, so each C-shaped platform has two adjustable rods 2 connected to each side of the opening. The two diagonal bracing angle steels 112 on the same side of the opening of each C-shaped platform form an asymmetrical figure-eight structure. The angle between the diagonal bracing angle steel 112 closer to the opening and the C-shaped steel plate 111 is greater than the angle between the other diagonal bracing angle steel 112 and the C-shaped steel plate 111.

[0079] When two C-shaped platforms are connected to form a rectangular ring structure working platform 1, among the four diagonal bracing angle steels 112 on the same side of the openings of the two C-shaped platforms, the two inner diagonal bracing angle steels 112 form a symmetrical V-shaped structure, and the two outer diagonal bracing angle steels 112 form a symmetrical figure-eight structure.

[0080] The diagonal bracing angle steel 112 and the side of the C-shaped fence 115 on the same side are located in the same vertical plane.

[0081] Please refer to the reference. Figures 1 to 3 , Figure 5 The flat steel rod 121 is set as a rectangular steel rod. The toe plate 123 is set as a vertical rectangular plate, and can be set as a C-shaped plate with a right angle bend. The toe plate 123 can be welded to the bottom of the C-shaped fence 115.

[0082] Please refer to the reference. Figure 1 , Figure 2 , Figure 4 and Figure 5Both the lower channel steel 211 and the upper channel steel 212 are set as right-angled channel steels. Each adjustable rod 2 may include a pair of symmetrically arranged lower channel steels 211 and a pair of symmetrically arranged upper channel steels 212, and the lower and upper parts of the I-beam 220 are respectively movably set in the pair of lower channel steels 211 and the pair of upper channel steels 212.

[0083] Please refer to the reference. Figure 1 and Figure 5 In each C-shaped platform, the top ends of the two outermost angle steels 112 on the same side of the opening are welded to the two outermost lower channel steels 211. Furthermore, the bottom ends of the four angle steels 112 of each C-shaped platform are welded to the four corners of the C-shaped platform.

[0084] Please refer to the reference. Figure 1 , Figure 2 , Figure 4 and Figure 5 Five pairs of lower adjusting screw holes are respectively opened on both sides of the lower channel steel 211 and the lower two side flanges of the I-beam 220, and lower adjusting bolts 231 are respectively installed in the lower adjusting screw holes of both. Five pairs of upper adjusting screw holes are respectively opened on both sides of the upper channel steel 212 and the upper two side flanges of the I-beam 220, and upper adjusting bolts 232 are respectively installed in the upper adjusting screw holes of both.

[0085] Five pairs of lower and upper adjusting screw holes are evenly arranged from top to bottom.

[0086] Please refer to the reference. Figure 1 and Figure 2 The top truss 3 is formed by welding multiple square tubes to create an isosceles triangle. The top of the upper channel steel 212 of each pair of adjustable rods 2 is welded to both ends of the base of a top truss 3. That is, each pair of adjustable rods 2 and the connected top truss 3 are located in the same vertical plane.

[0087] like Figure 2 As shown, a support channel steel 310 is welded to the middle of the bottom edge of the top truss 3.
