Description

Technical Field

[0001] This application relates to the field of guardrail maintenance technology, and more specifically, to a folding maintenance shed for bridge guardrails. Background Technology

[0002] Bridge railings are concrete structures, and because they are used on bridges, their length is adapted to the length of the bridge, making them longer than ordinary railings. During the concrete pouring process, the concrete needs to be cured. Traditional curing methods involve using multiple support frames erected above the railing to cover it with a protective layer. However, this process requires manually erecting many support frames, and also manually storing them, making operation inconvenient. For example, the curing equipment described in CN110172926 A involves a trolley, requiring a complex control system and structure, increasing the cost of bridge railing curing, and also requiring a matching track structure, making movement difficult. Summary of the Invention

[0003] This application addresses the aforementioned deficiencies in the prior art. There is a need for a foldable curing shed for bridge railings that can solve the problems of complex and costly moving and storing curing equipment for bridge railings.

[0004] In a first aspect, this application provides a folding curing shed for bridge railings. The folding curing shed includes multiple curing frames, at least some of which have pulleys at their bottom. Adjacent curing frames are connected by a rotating frame to retract or expand adjacent frames. Each curing frame includes a main body and a folding rod located on top of the main body. The folding rod has two folding points. When folded at the two folding points, the folding rod and the main body form an inverted U-shaped structure, which is used to accommodate the railing.

[0005] In some embodiments, a counterweight is provided on one side of the health frame, and the counterweight and the inverted U-shaped structure are respectively located on both sides of the main body.

[0006] In some embodiments, the counterweight is a foldable rod-shaped counterweight, and the counterweight includes at least one folding point located at the connection between the counterweight and the main body.

[0007] In some embodiments, the folding rod includes three segmented rods connected in sequence, and a power structure is provided at the folding point of the folding rod. The power structure includes a lifting machine and a cooperating rod, which are respectively located on two adjacent segmented rods at the folding point.

[0008] In some embodiments, a pivot is provided at the connection point of the three segments of the folding rod.

[0009] In some embodiments, the rotating frame includes a square frame, an upper rotating shaft, and a lower rotating shaft, the upper rotating shaft and the lower rotating shaft passing through two opposite sides of the square frame, and the two ends of the upper rotating shaft and the lower rotating shaft being rotatably connected to the main body.

[0010] In some embodiments, the main body is a frame structure, the upper and lower rotating shafts of the rotating frame are respectively connected to the inner side of the main body, and the upper and lower rotating shafts are respectively connected to the adjacent health care frame.

[0011] In some embodiments, the rotating frame further includes a connecting rod that connects four adjacent health-preserving frames. The three adjacent health-preserving frames are, in sequence, a first health-preserving frame, a second health-preserving frame, a third health-preserving frame, and a fourth health-preserving frame. The connecting rod is connected in sequence to the top of the first health-preserving frame, the upper rotating shaft of the second health-preserving frame, the lower rotating shaft of the third health-preserving frame, and the bottom of the fourth health-preserving frame.

[0012] The bridge railing curing sheds provided in the various embodiments of this application allow the curing frame to slide via pulleys at the bottom of the curing shed. When the curing frame slides, adjacent curing frames can be retracted or expanded. Adjacent curing frames are connected by a rotating frame, which ensures that the connection remains even when the curing frames are retracted or expanded, facilitating the formation of a regular curing shed for the maintenance of the railing. The folding rod and the main body cooperate to form an inverted U-shaped structure to create an insulation layer for the railing. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solutions of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific examples, but these are not intended to limit the scope of this application.

[0021] The terms “first,” “second,” and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used for distinction. Terms such as “including” or “comprising” mean that the element preceding the term covers the element listed after the term, and do not exclude the possibility of covering other elements as well.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of this application, a foldable curing shed for bridge railings is provided. The foldable curing shed includes multiple curing frames. At least some of the multiple curing frames are provided with pulleys 1 at their bottom. Two adjacent curing frames are connected by a rotating frame 4 to retract or expand the curing frames. The curing frame includes a main body 2 and a folding rod 3 provided on the top of the main body 2. The folding rod 3 has two folding points. When the two folding points of the folding rod 3 are folded, the folding rod 3 and the main body 2 form an inverted U-shaped structure. The inverted U-shaped structure is used to accommodate the railing 5.

[0023] The curing frame is equipped with casters at its bottom, allowing multiple frames to be moved by pushing or other means to adjust the distance between them, thereby adjusting the length of the curing chamber, storing the curing chamber, or unfolding it. The entire curing chamber can be stored and organized in one unit, eliminating the need for multiple support frames and making it very convenient to move. Using it for the curing of bridge railings 5 ​​can save manpower and costs.

[0024] When the folding rods 3 of the curing frame form an inverted U-shape, they can hold the guardrail 5 in place. Multiple curing frames form an insulation layer for the guardrail 5, thus curing it. During curing, the density of the insulation layer can be adjusted by changing the distance between adjacent curing frames. If necessary, other coverings can be placed on top of the curing shed.

[0025] Adjacent health-preserving frames are connected by rotating frames 4, which ensures that the frames remain connected when they are contracted or expanded, making it easy to form a regular health-preserving shed extending along the direction of the railing for the purpose of maintaining the railing's health.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a counterweight 6 is provided on one side of the health-preserving frame, and the counterweight 6 and the inverted U-shaped structure are respectively located on both sides of the main body 2. The counterweight 6 is used to balance the weight on both sides of the main body 2 when the rotating frame 4 forms the inverted U-shaped structure. This helps to maintain the stability of the health-preserving shed.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the counterweight 6 is a foldable rod-shaped counterweight 6, and the counterweight 6 includes at least one folding point located at the connection between the counterweight 6 and the main body 2. The counterweight 6 can be folded up, which facilitates the movement and placement of the health-preserving shed when storing it.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the folding rod 3 includes three sequentially connected segmented rods. A power structure is provided at the folding point of the folding rod 3. The power structure includes a lifting machine 7 and a cooperating rod 8, which are located on two adjacent segmented rods at the folding point. The lifting machine 7 can be a cylinder or a hydraulic cylinder, etc. As shown, there are two folding power structures extending upwards from the main body 2. The segmented rod folds when the hydraulic rod of the hydraulic cylinder extends from the power structure closest to the main body 2. The segmented rod folds when the hydraulic rod of the hydraulic cylinder extends from the power structure furthest from the main body 2.

[0029] In some embodiments, a pivot is provided at the connection point of the three segmented rods of the folding rod 3 to facilitate folding of the segmented rods.

[0030] like Figure 4 and Figure 5As shown, in some embodiments, the rotating frame 4 includes a square frame 9, an upper rotating shaft 10 and a lower rotating shaft 11, the upper rotating shaft 10 and the lower rotating shaft 11 passing through two opposite sides of the square frame 9, and the two ends of the upper rotating shaft 10 and the lower rotating shaft 11 being rotatably connected to the main body 2 respectively.

[0031] like Figure 1 As shown, in some embodiments, the main body 2 is a frame structure, and the upper rotating shaft 10 and lower rotating shaft 11 of the rotating frame 4 are respectively connected to the inner side of the main body 2, and the upper rotating shaft 10 and lower rotating shaft 11 are respectively connected to adjacent health care frames. The rotating frame 4 connects adjacent health care frames and facilitates the adjustment of the distance between adjacent health care frames.

[0032] like Figure 5 As shown, in some embodiments, the rotating frame 4 further includes a connecting rod 12, which connects four adjacent health-preserving frames. These four adjacent frames are, in sequence, a first health-preserving frame, a second health-preserving frame, a third health-preserving frame, and a fourth health-preserving frame. The connecting rod 12 sequentially connects the top of the first health-preserving frame, the upper rotating shaft 10 of the second health-preserving frame, the lower rotating shaft 11 of the third health-preserving frame, and the bottom of the fourth health-preserving frame. The connecting rod 12 improves the stability of the multiple health-preserving frames.
