Description

Technical Field

[0001] The utility model relates to the field of bridge construction equipment, and more specifically, to an auxiliary bridge construction device. Background Art

[0002] During the construction of elevated bridges across highways, since the erection of protective sheds takes up a large space and requires the use of driving lanes, which greatly increases the cost of the project, before each construction of the upper bridge section in the highway traffic area, it is necessary to apply for the closure of traffic on that section of the highway and report to the highway traffic police, highway operations, highway administration, and national defense optical cable maintenance departments. The entire process takes more than three months to complete, which greatly prolongs the construction period.

[0003] The utility model patent with authorization announcement number CN214328578U discloses a highway bridge maintenance device, including a bridge body, a mobile vehicle and a hanging basket frame. The top surfaces of the two mobile vehicles are fixedly connected with a telescopic frame A, the top surfaces of the two telescopic frames A are fixedly connected with a connecting frame, the bottom inner wall of the connecting frame is fixedly connected with two motors, and the sides of the two motors away from each other are fixedly sleeved with a wheel through a transmission shaft. The bottom surface of the connecting frame is fixedly connected with two telescopic frames B, and the bottom surface of each telescopic frame B is fixedly connected with four clamping blocks, and each clamping block is provided with a clamping hole on the front side. The top surface of the hanging basket frame is provided with eight clamping slots, and the eight clamping slots are respectively located at the left and right ends of the hanging basket frame. The eight clamping slots are respectively movably inserted with the eight clamping blocks, and the front and rear inner walls of each clamping slot are provided with holes, and each hole is movably sleeved with a staple between each clamping hole. The structure is simple, which effectively improves the maintenance efficiency and ensures safety.

[0004] In the above scheme, two telescopic frames A support the connecting frame, and the connecting frame provides tension. This type of steel structure connecting frame is generally used in the construction of small-span bridges, generally about three or four meters; when the bridge span is large, a longer connecting frame is required, and the overall weight of the connecting frame will be very large, which is very inconvenient to transport and install, and the manufacturing and transportation costs are high. Utility Model Content

[0005] The utility model aims to overcome the defects of the above-mentioned prior art and provide a bridge auxiliary construction device for solving the technical problem that when the span of the bridge is large, the connecting frame to be used is long, the overall weight of the connecting frame will be very large, the transportation and installation is very inconvenient, and the manufacturing and transportation costs are high.

[0006] The technical solution adopted by the utility model is a bridge auxiliary construction device, comprising a mobile frame, a hanging basket frame and a lifting device; the mobile frames are provided with two, the two mobile frames are connected by ropes, the two mobile frames are respectively equipped with lifting devices, the two lifting devices are respectively connected to the two ends of the hanging basket frame, and are used to lift or lower the hanging basket frame.

[0007] In this solution, ropes are used to connect two mobile frames. The ropes can be used in the construction of long-span bridges, usually reaching about fifteen to twenty meters. Compared with the steel structure connecting frames, the ropes are light in weight, can be wound around a disc during transportation, occupy less space, can be bent arbitrarily during erection, have a low erection difficulty, and have lower manufacturing and transportation costs.

[0008] Furthermore, a moving component is provided at the bottom of the mobile frame. The moving component includes moving wheels installed at the bottom of the mobile frame. By means of the moving wheels, it can move on the bridge surface, and by moving, the position of this construction device on the bridge surface can be adjusted, facilitating the replacement of positions for construction.

[0009] Furthermore, the moving component further includes a track member. The moving wheels are in rolling cooperation with the track member, and the track member is laid on the bridge surface during construction. The track member can be a railway track, a track, etc. After it is laid on the bridge surface, the moving wheels move on the track member, which will not damage the bridge surface, and the rolling cooperation between the track and the moving wheels has a small friction force, making the movement smoother.

[0010] Furthermore, the track member is an I-beam or a U-shaped steel. I-beams and U-shaped members are common materials used at the construction site, are easy to find, and have low costs.

[0011] Furthermore, the mobile frame includes a vertical frame, a diagonal brace frame, and a horizontal frame. The horizontal frame and the diagonal brace frame are both fixedly connected to one side of the top of the vertical frame, and the horizontal frame, the diagonal brace frame, and a part of the vertical frame form a triangular structure. The triangular structure has extremely high stability and strong load-bearing capacity.

[0012] Furthermore, the lifting device is a winch.

[0013] Furthermore, the winch is installed at the top of the vertical frame, and the moving component is installed at the bottom of the vertical frame. When installing, just push the vertical frame to move. The weight of the winch directly drops vertically onto the moving wheels, with strong stability during movement and not being prone to tipping over, making the installation more convenient.

[0014] Furthermore, guide wheels are provided on the diagonal brace frame, and the cable in the winch is connected to the hanging basket frame through the guide wheels. The guide wheels mainly play a guiding role to enable the winch to vertically lift the hanging basket frame.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: In this solution, ropes are used to connect two mobile frames. The ropes can be used in the construction of long-span bridges, usually reaching about fifteen to twenty meters. Compared with the steel structure connecting frames, the ropes are light in weight, can be wound around a disc during transportation, occupy less space, can be bent arbitrarily during erection, have a low erection difficulty, and have lower manufacturing and transportation costs.

[0021] The attached drawings of the present utility model are only for illustrative purposes and should not be construed as a limitation to the present utility model. For better illustrating the following embodiments, some components in the attached drawings will be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the attached drawings may be omitted.

[0022] As Figure 1 and 2 shown, this solution discloses a bridge auxiliary construction device, including a moving frame 1, a suspended basket frame 2 and a lifting device 3; there are two moving frames 1, the two moving frames 1 are connected by a rope 4, and lifting devices 3 are respectively installed on the two moving frames 1, and the two lifting devices 3 are respectively connected to both ends of the suspended basket frame 2 for lifting or lowering the suspended basket frame 2.

[0023] In this solution, the two moving frames 1 are connected by a rope 4. The rope 4 can be used in the construction of large-span bridges, usually reaching about fifteen to twenty meters. Compared with the connecting frame made of steel structure, the rope 4 is light in weight, can be wound around a disk during transportation, occupies a small space, can be bent arbitrarily during erection, has a small erection difficulty, and has a lower manufacturing and transportation cost. The rope 4 in this solution can be a rope or chain that meets the tensile strength, such as steel wire rope or steel cable.

[0024] As Figure 4 shown, a moving component 5 is arranged at the bottom of the moving frame 1, and the moving component 5 includes moving wheels 11 installed at the bottom of the moving frame 1. By means of the moving wheels 11, it can move on the bridge deck, and by moving, the position of this construction device on the bridge deck can be adjusted, which is convenient for changing the position for construction.

[0025] The moving component 5 further includes a track member 6. The moving wheel 11 is in rolling cooperation with the track member 6. During construction, the track member 6 is laid on the bridge deck. The track member 6 can be a railway track, a track, etc. After it is laid on the bridge deck, the moving wheel 11 moves on the track member 6 without damaging the bridge deck. Moreover, the rolling cooperation between the track and the moving wheel 11 has a small frictional force, making the movement smoother. The track member 6 is an I-beam or a U-shaped steel. I-beams and U-shaped members are common materials used at construction sites, easy to find, and have a low cost.

[0026] As Figure 3 shown, the moving frame 1 includes a vertical frame 7, a diagonal brace frame 8, and a horizontal frame 9. The horizontal frame 9 and the diagonal brace frame 8 are both fixedly connected to one side of the top of the vertical frame 7, and the horizontal frame 9, the diagonal brace frame 8, and a part of the vertical frame 7 form a triangular structure. The triangular structure has extremely strong structural strength, thereby improving the load-bearing capacity of the moving frame 1 and enabling it to lift a heavier hanging basket frame 2.

[0027] The lifting device 3 is a winch 12. The winch 12 is installed on the top of the vertical frame 7, and the moving component 5 is installed at the bottom of the vertical frame 7. During installation, it is only necessary to push the vertical frame 7 to move. The weight of the winch 12 directly falls vertically onto the moving wheel 11, with strong stability during movement and not easily tipping over, making the installation more convenient.

[0028] A guide wheel 10 is provided on the diagonal brace frame 8. The wire rope inside the winch 12 is connected to the hanging basket frame 2 through the guide wheel 10. The guide wheel 10 mainly plays a guiding role to enable the winch 12 to vertically lift the hanging basket frame 2.

[0029] During installation, first lay two track members 6 on the bridge deck, then place the two moving frames 1 on the two track members 6 respectively. By rolling the moving wheels 11, move the moving frames 1 on the track members 6 to the predetermined positions. After that, connect the two moving frames 1 through the rope 4. Extend the two wire ropes of the two winches 12 on the moving frames 1 down from both sides of the bridge and fix them to the two ends of the hanging basket frame 2 respectively. Then, lift the hanging basket frame 2 to the working height by winding the wire ropes with the winches 12. After that, the construction workers can carry out construction on the hanging basket frame 2. After the construction at one position is completed, move this bridge construction device to another position through the moving frame 1 and continue the construction. During construction, vehicles can continue to pass under the hanging basket frame 2 without affecting traffic.
