Description

Technical Field

[0001] The invention belongs to the technical field of bridge reinforcement devices, and particularly relates to a bridge reinforcement vehicle. Background Art

[0002] With socioeconomic development, traffic volume continues to increase. The increase in vehicles and the rising proportion of heavy-loaded vehicles have resulted in bridges bearing loads far exceeding design expectations. Beam ribs are the primary load-bearing components of bridges. Under long-term, excessive traffic loads, the stress within the beam ribs gradually increases. Carbonation of the concrete beam ribs can lead to corrosion of the internal steel reinforcement. Furthermore, the bottom beam ribs of bridges are exposed to the elements, subject to various factors such as rainwater erosion and chemical corrosion. Rainwater can penetrate tiny cracks within the beam ribs. When the temperature drops, the water freezes and expands, exacerbating the cracks. Consequently, bridges can experience material aging over the long term.

[0003] The reinforcement of the beam ribs requires the use of reinforcement plates. The reinforcement plates are slat structures that are fitted and fixed to the bottom and both sides of the beam ribs. They can increase the cross-sectional inertia moment of the beam ribs, thereby improving the beam ribs' ability to resist deformation. The slat structure is finally fitted and fixed to the beam rib position by punching holes and applying concrete. In the existing technology, the fixation of the bottom slats and side slats requires the application of concrete on the ground, and requires lifting equipment for lifting, flipping of the side slats and other operations. The entire construction process is cumbersome and the construction efficiency is low, resulting in problems such as bridge quota occupation and traffic congestion during construction. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a bridge reinforcement vehicle to assist in the rapid reinforcement of beam ribs and improve construction efficiency.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

The two support strips are respectively supported on the bottom sides of the contact edges of the bottom strip and the side strip. The support wheels are respectively supported on the bottom sides of the side strips. The concrete funnel moves along the cross rail, and the concrete funnel smears concrete on the upper surfaces of the bottom strip and the side strip. As the scissor-type lifting platform rises, the bottom strip rests on the bottom side of the beam rib. As the vertical hydraulic cylinder and the horizontal hydraulic cylinder extend, the side strips are rotated and attached to both sides of the beam rib.

[0007] Furthermore, a horizontal telescopic cylinder is provided on the column, and a support column is fixedly provided on the end of the horizontal telescopic cylinder upwards, and the support column is fixedly connected to the bottom side of the support bar.

[0008] Furthermore, an insertion column is provided at the end of the horizontal telescopic cylinder on one side, and an insertion hole is provided at the end of the horizontal telescopic cylinder on the other side, and the insertion column is slidably arranged in the insertion hole.

[0010] Furthermore, a support seat is provided on the upper edge of the aggregate bin for slidingly supporting the output shaft of the horizontal telescopic cylinder.

[0011] Furthermore, vertical frames are provided at both ends of the aggregate bin, and the vertical frames are vertical elastic structures. A horizontally adjustable baffle is provided on the vertical frames.

At this time, the bottom and side bars are in the same plane. Figure 5 , the concrete funnel moves along the horizontal rail. When the concrete funnel moves along the bottom and side strips, the output port of the concrete funnel is located above the bottom and side strips and there is a certain gap. As the concrete funnel moves, concrete is smeared on the surface of the bottom and side strips. After the concrete is smeared, the scissor-type lifting platform rises to align the bottom strips with the beam ribs. At this time, the vertical hydraulic cylinder and the horizontal hydraulic cylinder are extended, and one side of the side strips is supported by the support strips.

The vehicle body is also provided with a support wheel 641 connected to the support wheel. The cross rail 7 is parallel to the support bar 5, and a concrete funnel 71 is movable on the cross rail 7. The bottom plate for reinforcing the beam rib 1 and the side strips 22 on both sides of the beam rib 1 are arranged side by side in the form of side strips 22-bottom strips 21-side strips 22. The two support bars 5 are respectively supported on the bottom sides of the contact edges of the bottom strips 21 and the side strips 22. The support wheels 641 are respectively supported on the bottom sides of the side strips 22. The concrete funnel 71 moves along the cross rail 7. The concrete funnel 71 smears concrete on the upper surfaces of the bottom strips 21 and the side strips 22. As the scissor-type lifting platform 4 rises, the bottom strips 21 rest against the bottom side of the beam rib 1. As the vertical hydraulic cylinder 63 and the horizontal hydraulic cylinder 64 extend, the side strips 22 are rotated and attached to both sides of the beam rib 1.

[0024] In this solution, the vehicle body 3 is moved to the bottom of the beam rib 1 to be reinforced. At this time, the scissor lift platform 4 is retracted. At this time, the two side panels 22 and the bottom panel 21 are in the form of Figure 3The two support bars 5 are respectively supported on the bottom sides of the contact edges of the bottom bar 21 and the side bar 22, and the support wheels 641 are respectively supported on the bottom sides of the side bar 22. At this time, the bottom bar 21 and the side bar 22 are on the same plane. Figure 5 , the concrete funnel 71 moves along the cross rail 7. When the concrete funnel 71 moves along the bottom plate slats 21 and the side plate slats 22, the output port 82 of the concrete funnel 71 is located above the bottom plate slats 21 and the side plate slats 22 and there is a certain gap. As the concrete funnel 71 moves, concrete is smeared on the surface of the bottom plate slats 21 and the side plate slats 22. After the concrete smearing is completed, the scissor-type lifting platform 4 rises to align the bottom plate slats 21 with the beam rib 1. At this time, the vertical hydraulic cylinder 63 and the horizontal hydraulic cylinder 64 are extended, and one side of the side plate slats 22 is supported by the support bar 5. The two side plate slats 22 are flipped upward around the support bar 5 to achieve the side plate slats 22 being attached to both sides of the beam rib 1. After the attachment is completed, the bottom plate 21, the side plate slats 22 and the beam rib 1 can be connected and fixed. After the fixing is completed, the scissor-type lifting platform 4, the vertical hydraulic cylinder 63 and the horizontal hydraulic cylinder 64 are retracted to return to the initial state; this bridge reinforcement vehicle is suitable for reinforcing the bridge beam rib 1 above the ground, and the mobile body 3 is used to support and transport the bottom plate strips 21 and side plate strips 22 for reinforcement, and through the concrete smearing above the mobile body 3, the overall lifting, the side plate strips 22 flipping and other structures, the bottom plate strips 21 and the side plate strips 22 are fitted at one time, assisting construction personnel to fix the bottom plate strips 21, the side plate strips 22 and the beam rib 1. This device replaces manual smearing of concrete, the transportation, placement and fixing of the bottom plate strips 21 and the side plate strips 22, with simple operation and precise movement, reduces the reinforcement period, and helps to improve the construction efficiency of the entire beam rib 1 reinforcement.

[0025] In a further solution, Figure 3 As shown, a horizontal telescopic cylinder 65 is further provided on the column 61 , and a support column 651 is fixedly provided on the end of the horizontal telescopic cylinder 65 , and the support column 651 is fixedly connected to the bottom side of the support bar 5 .

[0026] In this solution, the support bar 5 is connected to the column 61 through a horizontal telescopic cylinder 65. The horizontal position of the support bar 5 can be adjusted by the horizontal telescopic cylinder 65, so that this device can adapt to bottom strips 21 of different widths, thereby improving the versatility of this device.

[0027] In a further solution, Figure 3 As shown, an insertion column is provided at the end of the horizontal telescopic cylinder 65 on one side, and an insertion hole is provided at the end of the horizontal telescopic cylinder 65 on the other side, and the insertion column is slidably arranged in the insertion hole.

[0028] By setting up a plug-in column and socket matching structure, the ends of the two horizontal telescopic cylinders 65 support each other and are located in the same straight line moving path, which is conducive to maintaining the horizontal position of the support bar 5, avoiding deformation and displacement of the support bar 5, and improving the supporting capacity of the support bar 5.

[0029] In a further solution, Figure 3 and Figure 4 As shown, the scissor-type lifting platform 4 is also provided with a collection bin 8 for catching falling concrete. The opening of the collection bin 8 is facing upward. The collection bin 8 is located below the support bar 5. The side of the collection bin 8 is inclined. A mesh plate 81 is provided above the bottom side of the collection bin 8. The bottom side of the collection bin 8 is also provided with an outlet 82.

[0030] By setting up the aggregate bin 8, the concrete that falls during the construction process is collected to prevent the concrete from falling onto the mobile body 3 and the scissor-type lifting platform 4. The aggregate bin 8 is provided with a mesh plate 81 to assist the construction workers in standing. The concrete falls into the bottom of the aggregate bin 8 through the mesh plate 81 and flows out through the outlet 82.

[0031] In a further solution, Figure 3 As shown, the upper edge of the collecting bin 8 is provided with a support seat 83 for slidingly supporting the output shaft of the horizontal telescopic cylinder 65. This further strengthens the supporting capacity of the horizontal telescopic cylinder 65 and the maintenance of the moving path.

[0032] In a further solution, Figure 5 and Figure 6 As shown, a stand 84 is provided at each end of the aggregate bin 8. The stand 84 is a vertical elastic structure. A horizontally adjustable baffle 85 is provided on the stand 84. After the concrete funnel 71 moves out of the side slats 22 and the bottom slats 21, the baffle 85 blocks the outlet 82 of the concrete funnel 71.

[0033] In this solution, a vertical elastic stand 84 and a baffle 85 are provided to block the lower outlet 82 of the concrete funnel 71 that moves out of the ends of the bottom plate slats 21 and the side plate slats 22 to prevent excessive concrete from flowing out. As the concrete funnel 71 moves out of the baffle 85, the concrete funnel 71 is located above the bottom plate slats 21 and the side plate slats 22 with a gap, and the concrete smearing can be completed. Moreover, as the bottom plate slats 21 rise, when the bottom plate slats 21 rest against the bottom sides of both sides, the beam rib 1 presses down the baffle 85, and the baffle 85 will not interfere with the fitting of the bottom plate slats 21.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
