Description
Technical Field
[0001] This utility model relates to the field of maintenance shed technology, specifically to a mobile maintenance shed for precast bridge components. Background Technology
[0002] Precast bridge components refer to concrete components prefabricated in factories or on-site according to design specifications. These components include beams, slabs, and columns, and are used for assembly on construction sites. Precast bridge components are the material basis of industrialized construction, which can accelerate construction speed and improve project quality. Currently, most precast bridge component manufacturing companies use assembly line construction in their precast beam yards. Each assembly line is equipped with gantry cranes and mobile curing sheds. The mobile curing sheds are equipped with sprinkler systems and temperature and humidity monitoring devices, allowing the pouring, curing, and moving of precast bridge components to be carried out in an orderly manner.
[0003] In the actual maintenance process, the use of mobile maintenance sheds is necessary because bridge precast components include beams, slabs, columns, etc. To accommodate various components of different sizes, the mobile maintenance sheds on the production line are made relatively large. However, we have found that for small precast components, the larger space inside the maintenance shed has a larger air volume, making it easier to form a temperature gradient inside the maintenance shed, i.e., the bottom is colder and the top is hotter. In order to maintain the stability and uniformity of the environment inside the maintenance shed, the sprinkler system needs to be involved for a long time, which makes the maintenance cost of precast components high. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a mobile curing shed for bridge precast components. This shed can adjust the height of its roof according to the size of the bridge precast components, thereby changing the size of the internal space. This reduces the impact of temperature gradients within the shed on the precast beam components, shortens the intervention time of the spraying system, and ultimately lowers the curing cost of bridge precast components.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile curing shed for precast bridge components, comprising a curing shed body, a track, and a spraying system. The lower end of the curing shed body is provided with a set of rollers that cooperate with the track. The spraying system is located within the curing shed body. The curing shed body includes a shed roof and two sets of shed walls, which are respectively located at both ends of the width direction of the shed roof, and the shed roof is movably connected to the shed walls on both sides. The curing shed also includes a lifting mechanism and two sets of electric roller shutters. The lifting mechanism is installed on the upper side of the shed roof, and the execution end of the lifting mechanism is connected to the shed roof. The two sets of electric roller shutters are located at both ends of the length direction of the shed roof.
[0006] Preferably, the wall of the maintenance shed includes a frame and side tiles. The frame is composed of several I-beams and connecting rods, and the side tiles are installed on the outside of the frame. The roof of the maintenance shed includes a frame, roof tiles and several connecting blocks. The roof tiles are installed at the lower end of the frame, and the connecting blocks are distributed at both ends of the frame in the width direction. The connecting blocks are correspondingly arranged with the I-beams and are slidably connected.
[0007] Preferably, the connecting block has a U-shaped structure, and the outer end of the connecting block has a slot; the inner end of the corresponding I-beam is at least partially located inside the connecting block.
[0008] Preferably, the lifting mechanism is provided in two sets, and the two sets of lifting mechanisms are installed corresponding to the two sets of maintenance shed walls; the lifting mechanism consists of a motor, a drum, a wire rope and a fixing plate, the motor is fixed to the top of the maintenance shed wall through the fixing plate; the output end of the motor is connected to the drum; one end of the wire rope is at least partially wound on the drum; the other end of the wire rope is connected to the frame.
[0009] Preferably, the roof of the maintenance shed includes a lifting seat that cooperates with the lifting mechanism; the lifting seat is fixedly mounted on the frame; and the lifting seat is provided with lifting lugs.
[0010] Preferably, the lifting base is fixedly connected to the frame by bolts or welding.

[0014] Preferably, the roof of the maintenance shed also includes sealing strips; the sealing strips are laid on the outer edge of the frame.
[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting the roof of the curing shed between the walls of the curing shed, the roof of the curing shed can be raised and lowered by a lifting mechanism. In actual curing, the height of the roof of the curing shed can be adjusted according to the size of the bridge precast components, thereby changing the size of the internal space of the curing shed, so as to reduce the impact of the temperature gradient inside the curing shed on the beam precast components, reduce the intervention time of the spraying system, and ultimately reduce the curing cost of bridge precast components.

[0022] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.
[0023] See Figure 1-5 In one embodiment of this utility model, a mobile curing shed for precast bridge components includes: two sets of curing shed walls 1, a lifting mechanism 2, a curing shed roof 3, two sets of electric roller shutter doors 4, and two tracks 5. The curing shed walls 1 are correspondingly arranged with the tracks 5. The bottom end of the curing shed walls 1 is provided with a set of rollers that cooperate with the tracks 5 so that the curing shed walls 1 can slide along the tracks 5 under the intervention of external force. The two sets of curing shed walls 1 are respectively placed at both ends of the width direction of the curing shed roof 3, and the curing shed roof 3 is movably connected to the curing shed walls 1 on both sides. The lifting mechanism 2 is fixedly installed on the top of the wall 1 of the maintenance shed. The execution end of the lifting mechanism 2 is connected to the top of the roof 3 of the maintenance shed by a steel wire rope. The roof 3 of the maintenance shed can be raised and lowered by the lifting mechanism 2 to change the size of the inner space of the maintenance shed. Two sets of electric roller shutter doors 4 are placed at both ends of the length of the roof 3 of the maintenance shed to close the inner space of the wall 1 and the roof 3 of the maintenance shed. Furthermore, the maintenance shed also includes a sprinkler system (not shown in the figure), which is installed on the inner side of the wall 1 and the lower side of the roof 3 of the maintenance shed.
[0024] Specifically, the maintenance shed wall 1 includes a frame and side tiles 12. The frame is composed of several I-beams 11 welded together with connecting rods. The several I-beams 11 are all vertically arranged and are distributed at intervals along the length of the maintenance shed wall 1. The side tiles 12 are fixedly installed on the outside of the I-beams 11.
[0025] The lifting mechanism 2 is provided in two sets, and the two sets of lifting mechanisms 2 are installed corresponding to the two sets of maintenance shed walls 1. The lifting mechanism 2 includes a motor 21, a drum 22, a wire rope 23 and a fixing plate 24. The motor 21 is installed on the top of the maintenance shed wall 1 through the fixing plate 24. The output shaft of the motor 21 is connected to the drum 22, and the wire rope 23 is at least partially wound on the drum 22.
[0026] The maintenance shed roof 3 includes a frame and roof tiles 33. The roof tiles 33 are fixedly installed on the lower end of the frame of the maintenance shed roof 3. The frame of the maintenance shed roof 3 is a frame structure welded together by several horizontal beams 31 and vertical beams 32. The maintenance shed roof 3 also includes two lifting seats 34, which are respectively located at both ends of the width direction of the frame of the maintenance shed roof 3. The two lifting seats 34 can be fixed by screws or welding. The two lifting seats 34 are arranged in a one-to-one correspondence with two sets of lifting mechanisms 2. The lifting seats 34 are provided with lifting lugs. The lifting mechanisms 2 are connected to the lifting seats 34 by passing steel wire ropes 23 through the lifting lugs. The maintenance shed roof 3 also includes several connecting blocks 35, which are distributed at intervals at both ends of the width direction of the frame of the maintenance shed roof 3. The frame of the maintenance shed roof 3 is fitted with the corresponding side of the maintenance shed wall 1 through the connecting blocks 35. It can be understood that the presence of the connecting blocks 35 can ensure the stability of the maintenance shed door-shaped or H-shaped structure.
[0027] In one embodiment, the connecting block 35 has a U-shaped structure, and a slot 351 is provided at the outer end of the connecting block 35, making the connecting block 35 an open U-shaped structure. The connecting block 35 on the same side is correspondingly arranged with the I-beam 11. After the connecting block 35 is sleeved on the inner end of the I-beam 11, the inner flange of the I-beam 11 is located inside the connecting block 35, and the web of the I-beam 11 is located in the slot 351. The connecting block 35 and the I-beam 11 are in clearance fit. Through such limiting, the connecting block 35 can not only ensure the relative position stability of the curing shed wall 1 and the curing shed roof 3, but also ensure that the curing shed roof 3 can slide up and down relative to the curing shed wall 1. The frame of the connecting block 35 and the curing shed roof 3 are fixedly connected by bolts.
[0028] In one embodiment, the outer edge of the roof 3 of the curing shed is provided with sealing strips. The sealing strips are laid on the outer edge of the frame. The sealing strips can fill and compensate for the gaps between the roof 3 of the curing shed, the wall 1 of the curing shed, and the electric roller shutter door 4, so as to make the airtightness of the inner space of the curing shed higher.
[0029] In one embodiment, the side tile 12 and the top tile 13 have the same structure, both being heat-insulating tiles. The structure of the heat-insulating tile mainly consists of two parts: a heat-insulating layer and a protective layer. The heat-insulating layer and the protective layer are bonded together. The heat-insulating layer can be made of heat-insulating materials such as polystyrene, polyurethane, and mineral wool, which play a role in heat insulation. The protective layer is made of aluminum alloy.
[0030] This technical solution involves installing a movable roof between the walls of the curing shed. The roof can be raised and lowered via a lifting mechanism. During actual curing, the height of the roof can be adjusted according to the size of the precast bridge components, thereby changing the size of the internal space of the curing shed. This reduces the impact of the temperature gradient inside the curing shed on the precast beam components, reduces the intervention time of the spraying system, and ultimately reduces the curing cost of precast bridge components.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
