Description

Technical Field

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

[0002] With the development of social economy, traffic flow is increasing. The increase in vehicles and the proportion of heavy-loaded vehicles have caused the loads on bridges to far exceed design expectations. The beam ribs are the main load-bearing components of the bridge. Under the long-term heavy traffic load, the stress inside the beam ribs will gradually increase. The concrete beam ribs may cause the internal steel bars to rust due to carbonization. In addition, the bottom beam ribs of the bridge are exposed to the natural environment and will be affected by various factors such as rain erosion and chemical corrosion. Rainwater may penetrate into the tiny cracks inside the beam ribs. When the temperature drops, the water freezes and expands, which will aggravate the expansion of the cracks. Therefore, the bridge will experience material aging during long-term use.

[0003] The reinforcement of the beam rib 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 rib. They can increase the cross-sectional inertia moment of the beam rib, thereby improving the beam rib's 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 prior art, the fixing 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

DETAILED DESCRIPTION

[0023] The present invention discloses a bridge reinforcement vehicle, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a mobile body 3, the top of the mobile body 3 is a plane for arranging other functional components, the top surface of the mobile body 3 is provided with a scissor-type lifting platform 4, the scissor-type lifting platform 4 is an existing hydraulic cylinder-driven lifting device, the top is a flat platform, the top of the scissor-type lifting platform 4 is provided with two mutually parallel support bars 5, each of the support bars 5 is provided with two turning supports 6 on the outside, the turning support 6 includes a column 61 fixed to the scissor-type lifting platform 4, a beam frame 62 is provided on the column 61 for vertical movement, a vertical hydraulic cylinder 63 is provided on the column 61, the vertical hydraulic cylinder 63 pushes the beam frame 62 to move, a horizontal hydraulic cylinder 64 is provided on the beam frame 62, and a support wheel 641 is provided at the end of the horizontal hydraulic cylinder 64, and the vehicle body is also provided with a support wheel 641 connected to the support wheel 64. A transverse rail 7 is parallel to the support bar 5, and a concrete funnel 71 is movably provided on the transverse rail 7. The bottom plate for reinforcing the bottom side of the beam rib 1 and the side strips 22 for reinforcing the two 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 transverse rail 7. The concrete funnel 71 applies concrete to 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 abut 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 strips 22 and the bottom strip 21 are in the state of being reinforced. 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 in 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 strip 21 and the side plate strip 22, the output port 82 of the concrete funnel 71 is located above the bottom plate strip 21 and the side plate strip 22 and there is a certain gap. As the concrete funnel 71 moves, concrete is smeared on the surface of the bottom plate strip 21 and the side plate strip 22. After the concrete is smeared, the scissor-type lifting platform 4 rises to align the bottom plate strip 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 strip 22 is supported by the support strip 5. The two side plate strips 22 are flipped upward around the support strip 5 to achieve the side plate strips 22 being attached to the two sides of the beam rib 1. After the attachment is completed, the bottom plate strip 21, the side plate strip 22 and the beam rib 1 can be connected and fixed After fixing, retract the scissor-type lifting platform 4, the vertical hydraulic cylinder 63 and the horizontal hydraulic cylinder 64 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 the side plate strips 22 for reinforcement, and through the concrete smearing, overall lifting, and flipping of the side plate strips 22 above the mobile body 3, the bottom plate strips 21 and the side plate strips 22 are fitted at one time, and the construction personnel are assisted in the fixation between 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, and is simple to operate, precise in movement, and reduces the reinforcement period, which 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 also provided on the column 61 , and a support column 651 is fixedly provided upward at 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, and the horizontal position of the support bar 5 can be adjusted by the horizontal telescopic cylinder 65, so that the device can adapt to bottom strips 21 of different widths, thereby improving the universal capability of the 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 opened 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 plug-in hole matching structure, the ends of the two horizontal telescopic cylinders 65 support each other and are located on the same straight line moving path, which is beneficial 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 the falling concrete, the opening of the collection bin 8 is 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, and an outlet 82 is also provided on the bottom side of the collection bin 8.

[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 material collecting bin 8 is provided with a support seat 83 for slidingly supporting the output shaft of the horizontal telescopic cylinder 65. The support capacity of the horizontal telescopic cylinder 65 and the maintenance of the moving path are further strengthened.

[0032] In a further solution, Figure 5 and Figure 6 As shown, two ends of the aggregate bin 8 are provided with upright frames 84 , and the upright frames 84 are vertical elastic structures. A horizontally adjustable baffle 85 is provided on the upright frames 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 slat 21 and the side plate slat 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 slat 21 and the side plate slat 22 with a gap, and the concrete can be applied. Moreover, as the bottom plate slat 21 rises and the bottom plate slat 21 rests against the bottom sides of both sides, the beam rib 1 presses down the baffle 85, and the baffle 85 does not interfere with the fitting of the bottom plate slat 21.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. 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.
