Description

Technical Field

[0001] The utility model relates to the technical field of box culvert construction equipment, in particular to a movable box culvert support system. Background Art

[0002] A box culvert is a tubular concrete structure widely used in water conservancy projects. Its cross-section is usually rectangular, and the tunnel body is made of cast concrete. During construction, formwork needs to be erected on the inside and outside. The inner formwork is often supported by a bracket made of overlapping steel pipes. Since box culverts are often long, they are often cast in sections along the length of the culvert. Therefore, for each section to be cast, it is necessary to first remove the bracket at the position of the previous completed section, and then erect a new bracket at the corresponding position to be cast.

[0003] However, on the one hand, this approach is easily restricted by the limited working space of the box culvert and its external foundation pit, resulting in low efficiency and speed of the disassembly and assembly of the bracket. On the other hand, there is a large amount of repetitive labor, which will seriously reduce the construction efficiency and speed of the box culvert. At the same time, the low construction speed will force construction workers to work in the foundation pit where the box culvert is located for a long time, which will lead to an increase in the exposure time of the foundation pit, and will greatly increase the safety risks of construction workers entering the foundation pit to work. Utility Model Content

[0004] The purpose of the utility model is to overcome the technical problem in the existing box culvert construction that each time a box culvert is constructed, the bracket needs to be disassembled and reassembled, the operation is cumbersome and repetitive, which seriously slows down the construction speed of the box culvert and increases the safety risks of the construction workers. A movable box culvert bracket system is provided.

[0005] In a first aspect, the present invention provides a movable box culvert support system, comprising:

[0006] The support body has a top surface for supporting the formwork of the box culvert, and the bottom of the support body is provided with supporting legs, the number of which is at least four, and the supporting legs are spaced apart along the length and width of the box culvert;

[0007] The walking mechanism is detachably connected to the bracket body. When the walking mechanism is connected to the bottom of the bracket body, the lowest point of the walking mechanism is lower than the lowest point of the support leg. The number of the walking mechanisms is at least four, and the walking mechanisms are spaced apart along the length and width of the box culvert.

[0008] The support body of this solution has two support modes. When the walking mechanism is removed, this solution is supported on the ground by the support legs, which has good stability and can reliably support the box culvert formwork. When the walking mechanism is installed, because the lowest point of the walking mechanism is lower than the lowest point of the support legs, the support legs will be separated from the ground, allowing the solution to stand on the ground through the walking mechanism. When the construction of a section of box culvert is completed, the workers can use other equipment to directly tow the solution as a whole to the location to be poured for the next section of the box culvert. It can be seen that this solution can avoid the repetitive labor of repeatedly disassembling and assembling the support, thereby significantly reducing the workload of box culvert construction, improving the efficiency and speed of box culvert construction, reducing the exposure time of the foundation pit, and reducing the safety risks of construction workers working in the foundation pit.

[0009] Preferably, it further comprises a vertical rod, the axis of which is arranged vertically, at least two connection points are arranged at intervals along the axial direction of the vertical rod, and the connection points are connected to the bracket body; the walking mechanism is detachably connected to the vertical rod.

[0010] Since the legs are no longer under stress after the walking mechanism is installed, the walking mechanism will bear the weight of the entire bracket body, so the connection strength between the walking mechanism and the bracket body is crucial; this solution connects the walking mechanism to the bracket body through a vertical rod, and can use the length of the vertical rod to set multiple connection points, thereby improving the connection reliability between the walking mechanism and the bracket body, while also avoiding single point failures, making this solution safer.

[0011] Preferably, a mounting hole is provided at the bottom of the vertical rod, and a mounting shaft is provided on the walking mechanism, and the mounting shaft can be inserted and pulled out of the mounting hole.

[0012] This solution recommends that the walking mechanism and the vertical rod be connected to each other in a plug-in manner, which can facilitate workers to quickly disassemble and assemble the walking mechanism.

[0013] Preferably, the cross-sectional shape of the installation shaft is polygonal or elliptical, and the cross-sectional shape of the installation hole matches the cross-sectional shape of the installation shaft.

[0014] This solution can prevent the walking mechanism from being misaligned after being inserted into the mounting hole, causing the direction of the walking mechanism to deviate from the preset direction.

[0015] Preferably, the vertical rod and the bracket body are connected by a steel pipe buckle.

[0016] This solution can facilitate the disassembly and assembly of the vertical rods, and the replacement of the positions of the vertical rods according to needs.

[0017] Preferably, the bracket body is provided with lifting points, which are used for docking with the lifting mechanism.

[0018] Since the lowest point of the walking mechanism is lower than the lowest point of the support leg, the walking mechanism is likely to interfere with the ground when installing the walking mechanism; this solution recommends setting a lifting point on the bracket body. When installing the walking mechanism, the lifting mechanism can be used to lift the bracket body, which makes it easier for workers to install the walking mechanism.

[0019] Preferably, the lifting mechanism comprises a jack.

[0020] This proposal recommends a specific lifting mechanism that can adapt to the narrow working space inside the box culvert.

[0021] Preferably, a traction point is provided on the bracket body, and the traction point is used for docking with the traction mechanism.

[0022] This solution can automatically move the bracket body through the traction mechanism, thereby reducing the manpower consumption during the movement of the bracket body, and can improve the movement efficiency and movement accuracy of the bracket body by utilizing the automated operation of the traction mechanism.

[0023] Preferably, the traction mechanism comprises a winch.

[0024] This proposal recommends a specific traction mechanism, which uses a winch to pull the bracket body. It only needs to connect the cable to the bracket body. Therefore, it can avoid large-scale modification of the bracket body, and even the unmodified bracket body can be used directly, thereby avoiding the situation where the bracket body structure is complicated and the manufacturing cost soars in order to make the bracket body adapt to the traction mechanism.

[0025] Preferably, the walking mechanism includes rollers.

[0026] This proposal recommends a specific walking mechanism that has the characteristics of simple structure, reliable operation, and low walking resistance. It can adapt well to the harsh construction site environment and can reduce the traction force requirements of the traction mechanism. In extreme cases, the box culvert support can even be moved by manpower.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The utility model provides a movable box culvert support system, which can switch between fixed and movable states through a detachably connected walking mechanism, so that it can not only stably support the formwork of the box culvert, but also directly move it to the position to be poured in the next section of the box culvert in an overall traction manner when the construction of one section of the box culvert is completed, avoiding the repetitive labor of repeatedly disassembling and assembling the support, and can greatly reduce the workload of box culvert construction, improve the working efficiency and speed of box culvert construction, reduce the exposure time of the foundation pit, and reduce the safety risks of construction workers in the foundation pit.
