Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a mobile formwork bottom formwork working vehicle and a through-hole system thereof. Background Art

[0002] At present, in the construction of upward mobile formwork, the middle section of the formwork is often transported through the hole by a bottom formwork work vehicle. In addition, when the bottom formwork is removed, the bottom formwork work vehicle can also be used as an operating platform for workers. When the formwork moves to the next hole for construction, the bottom formwork work vehicle also needs to pass through the hole with the formwork, but the current bottom formwork work vehicle passing through the hole is inefficient. Generally, the work vehicle is dismantled as a whole before passing through the hole, and then installed after the formwork is passed through the hole. This method requires working at high altitude, has high safety risks, is time-consuming, and has a high equipment occupancy rate. It does not meet the construction requirements of "assembly and rapidity".

[0003] In the existing mobile formwork bottom formwork work vehicle and through-hole construction method, a push-pull mechanism is set on the work vehicle truss beam, and a rotating mechanism and a longitudinal walking mechanism are set on the outside of the formwork to realize the work vehicle through-hole. However, this method will cause the following problems: (1) The push-pull mechanism structure is relatively complex, which increases the difficulty of manufacturing and construction. The construction space of the push-pull mechanism is limited, which is not conducive to manual construction operation and requires the cooperation of machinery and slideways to complete. (2) Since the rotating mechanism and the longitudinal walking mechanism are set on the outside of the formwork, the vertical bending moment of the upper through-hole crane is increased when passing through the hole, and the anti-overturning performance is poor, which is not suitable for construction in harsh environments such as strong winds.

[0054] In order to make the purpose, technical solutions and advantages of the present application clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] The present application provides a mobile mold frame 4 bottom mold working vehicle 1, such as Figure 1 , 3 As shown, it includes a work vehicle running mechanism 11, a truss frame 12 and a horizontal rotating hinge seat 13. The truss frame 12 includes an even number of segment beams 121 and a disassembly beam 122 that can be detachably spliced. In this embodiment, four segment beams 121 are arranged, and every two are arranged on both sides of the disassembly beam 122. The horizontal rotating hinge seat 13 is arranged between two segment beams 121 for folding the segment beam 121.

[0056] As an optimization of this embodiment, Figure 1 , 5 As shown in Figure 6, the working vehicle running track includes a running vehicle track laid on the movable mold frame 4 and a running wheel 112 mounted on the running vehicle track, which facilitates the movement of the working vehicle on the mold frame.

[0057] As an optimization of this embodiment, Figure 3 As shown, the disassembly beam 122 includes more than four connecting rods 1221 and flange pins 1222 arranged at both ends of the connecting rods 1221. In this embodiment, there are four connecting rods 1221. The connecting rods 1221 are used to connect the segment beams 121 on both sides to each other. When disassembly is required, the disassembly beam 122 can be disassembled by releasing the flange pins 1222. At the same time, the disassembly beam 122 is decomposed into four connecting rods 1221, which can be evenly placed in the segment beams 121 on both sides, which is convenient for placing parts and will not cause the segments 121 to fall off due to self-weight disturbance.

[0058] This embodiment also provides a through-hole system for a movable mold frame bottom mold working vehicle, such as Figure 1 ,5 As shown in 7, the through-hole system includes at least one pair of through-hole cranes 2 and at least one bottom mold working vehicle 1. In this embodiment, the through-hole crane 2 is Figure 5 There are two pairs, among which Figure 1 , 2 The through-hole crane 2 comprises a frame 21 arranged on the main beam of the mobile formwork 4, a rotary hinge shaft 22 arranged at one end of the frame 21 and a hoisting mechanism 23 arranged under the rotary hinge shaft 22, wherein the hoisting mechanism 23 is used to hoist the truss beam.

[0059] As an optimization of this embodiment, Figure 4 As shown, the frame 21 includes a triangular truss 211, which is arranged on the main beam of the mobile formwork 4 to play a supporting role. The cantilever beam 212 extends downward to reach a specified height, and one end of the shoulder beam 213 is connected to the cantilever beam 212, and the other end extends inward into the flange plate of the box beam. The rotating hinge shaft 22 is arranged at one end of the shoulder beam 213 extending into the flange plate, so that the torque of the mobile formwork 4 is closer to the inside when the work vehicle is lifted.

[0060] Further, such as Figure 1 , 2 As shown in , the hoisting mechanism 23 includes a plurality of electric hoists 231, which are evenly arranged at the lower part of the rotating hinge shaft 22.

Each of the electric hoists 231 corresponds to a segment beam 121, and one segment beam 121 is hoisted during lifting.

[0061] As an optimization of this embodiment, Figure 1 , 2 As shown, the through-hole system also includes at least one pair of temporary fixing devices 3, and the temporary fixing devices 3 are arranged on the side molds of the mobile mold frame 4. One end of each of the temporary fixing devices 3 is connected to the side mold of the mobile mold frame 4, and the other end is connected to the truss frame 12. The truss frame 12 is the most unstable when it is separated from the mobile mold frame 4, and it is easy to fall out and cause an accident. Therefore, the temporary fixing device 3 is arranged to ensure that it is not easy to fall off when the bottom mold work vehicle 1 unlocks the truss frame 12.

[0062] Furthermore, each of the temporary fixing devices 3 includes a connecting rod 31 and a lifting rope 32. The connecting rod 31 is arranged on the side mold of the movable mold frame 4. The lifting rope 32 is fixed on the connecting rod 31, and the other end is tied to the truss frame 12 or connected to the truss frame 12 using a hook to facilitate pulling up the truss frame 12.

[0066] S3. The connection between the disassembly beam 122 and the segment beam 121 of the bottom mold work vehicle 1 is disassembled, and the disassembly beam 122 is placed in one of the segment beams 121;

[0067] S4. Using the horizontal rotating hinge 13, the segment beam 121 is folded and stored, and then the segment beam 121 is lifted by the lifting mechanism 23, so that the truss frame 12 is stored under the box beam flange plate, so that it is easy to move the formwork 4 through the hole;

[0068] S5. Use the rotary hinge shaft 22 to rotate the hoisting mechanism 23 and adjust the direction of the segment beam 121 so that the length direction of the segment beam 121 after storage is along the bridge direction, so that it is easy to pass through the hole to prevent collision.

[0069] S6. The through-hole crane 2 moves to the next beam section along with the mobile formwork frame 4, unfolds the segment beam 121 and reinstalls the bottom form work vehicle 1.

[0070] In the embodiment where the through-hole assembly of the bottom mold work vehicle 1 includes at least one pair of temporary fixing devices 3, and the temporary fixing device 3 includes a connecting rod 31 and a hanging rope 32:

[0071] Add the following steps between step S1 and step S2:

[0072] S11. The lifting rope 32 is tied to the truss frame 12, and the lifting rope 32 is tightened to prevent the mobile bottom mold work vehicle 1 from slipping outward when the truss frame 12 is untied, causing danger;

[0073] Add the following steps between steps S3 and S4:

[0074] The segment beam 121 and the disassembly beam 122 are disassembled, and after confirming that the lifting mechanism 23 is firmly connected to the segment beam 121 , the lifting rope 32 is untied.

[0075] The bottom mold work vehicle and its through-hole system and method provided in this embodiment perform main actions on the inner side of the box girder flange plate, without the need for the complicated push-pull system in the prior art solution. The overall lateral bending moment is small and the ability to resist wind and overturn is strong.

[0076] The present application is not limited to the above-mentioned implementation modes. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
