[0002] In bridge construction, most of the installation of anti-collision guardrail construction templates for highway bridges in my country still uses cranes in conjunction with manual labor, which requires a large number of people. During the template erection and reinforcement process, construction workers rely on hanging baskets to work, which is labor-intensive, has high safety risks, and slows construction progress. Chinese patent CN111648232A discloses a bridge cast-in-place concrete anti-collision guardrail template trolley, including: a trolley body, a template hoisting device, and a working platform; wherein the trolley body includes: a base; a plurality of columns, one end of which is respectively connected to the two ends of the trolley; a plurality of cross arms, which are respectively connected to the other ends of the plurality of columns; the template hoisting device is arranged on the plurality of cross arms for hoisting the anti-collision guardrail template; the working platform is connected to the plurality of cross arms. Although the mechanization of anti-collision guardrail construction can be achieved, the structure is complex, there are many modules, the weight is large, and the cost of use is high.
[0003] The document with the prior art publication number CN216712773U provides an anti-collision guard beam construction trolley. The device is driven by a hydraulic motor through the trolley's walking mechanism, and no other mechanical equipment is required to assist in construction. The trolley is equipped with 4 electric hoists for template assembly or installation, and the template can be hoisted and moved forward or backward with the trolley, which is easy to operate. The trolley is equipped with a personnel construction hanging basket to meet the platform for workers to install the template on the outside of the bridge. The use of trolley construction meets the requirements of production safety, standardization, and neatness. The use of trolley construction does not require a large number of templates, which saves a lot of time in assembling templates during construction, improves construction speed, and greatly reduces construction costs.
[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, especially when the hanging basket is placed on the side of the bridge and below the bridge deck, there is a lack of necessary protection above it. When debris on the bridge deck falls to the position of the hanging basket, there will be a risk of construction workers in the hanging basket being injured.
[0005] In view of this, we propose an anti-collision guard beam construction trolley. Utility Model Content

[0032] Reference Figure 1-Figure 7 When the trolley needs to hoist tools or materials in the hanging basket 1, the reversible anti-falling object shielding member 3 is flipped upward, and the top of the hanging basket 1 is unobstructed, so the tools or materials can be lowered from the bridge deck to the hanging basket 1. When workers are working in the area below the bridge deck, the anti-falling object shielding member 3 is flipped and blocked above the hanging basket 1 to prevent falling objects. The anti-falling object shielding member 3 is horizontally extended toward the direction of the bridge and abutted against the side of the bridge to increase the shielding area, so as to prevent the workers' arms from being hit by falling objects after they extend their arms out of the hanging basket 1.
[0033] The anti-falling object shielding component 3 includes a baffle 31, a shaft 32 fixed to one side edge of the baffle 31, an extension plate 34 slidably set on the upper surface of the baffle 31, a first servo electric cylinder 35 fixed to the lower surface of the baffle 31 and two groups of second servo electric cylinders 38. The two ends of the two groups of second servo electric cylinders 38 are respectively connected to the baffle 31 and the hanging basket 1 axis for rotation. The first servo electric cylinder 35 is electrically connected to the first control switch 36, and the second servo electric cylinder 38 is electrically connected to the second control switch 37. The first servo electric cylinder 35 is fixed between the baffle 31 and the extension plate 34, and the shaft 32 is rotatably set between the two hangers 2.
[0034] Reference Figure 2-Figure 5The cylinder body of the first servo electric cylinder 35 is fixed under the baffle 31, the piston rod 351 of the first servo electric cylinder 35 is fixed on the extension plate 34, and the extension plate 34 slides toward one side of the bridge, so that the extension plate 34 is driven by the first servo electric cylinder 35 to adjust the upper shielding area. At the same time, the cylinder body shaft of the second servo electric cylinder 38 is rotatably connected to the hanging basket 1, and the piston rod 351 shaft is rotatably connected to the lower surface of the baffle 31, so that the baffle 31 is flipped and adjusted with the shaft rod 32 as the axis through the telescopic adjustment of the second servo electric cylinder 38, and the opening and closing of the first servo electric cylinder 35 is controlled by the first control switch 36, and the opening and closing of the second servo electric cylinder 38 is controlled by the second control switch 37.
[0035] Slide blocks 33 are symmetrically fixed to the upper surface of the baffle 31 , and the extension plate 34 is slidably arranged between the two slide blocks 33 . The first control switch 36 and the second control switch 37 are both fixed below the crossbeam of the hanging basket 1 .
[0036] Reference Figure 4-Figure 7 , there are sliding grooves on the opposite sides of the two sliders 33, and the extension plate 34 is slidably set in the two sliding grooves to guide the sliding direction of the extension plate 34. At the same time, the first control switch 36 and the second control switch 37 are fixed under the crossbeam of the hanging basket 1 to avoid accidentally touching the switch during construction.
[0037] A limiting block 21 is fixed to one side of the hanger 2 away from the shaft 32 .
[0038] Reference Figure 4 When the baffle 31 is in a horizontal state, the lower part of the baffle 31 rests on the limit block 21 so as to support the side of the baffle 31 away from the shaft 32 through the limit block 21 .
[0039] A mesh plate 4 is fixed between the hanging basket 1 and the baffle 31 , and the mesh plate 4 is placed on one side of the shaft 32 .
[0040] Reference Figure 1 When debris accumulates above the baffle 31 and the baffle 31 flips counterclockwise, the debris on the baffle 31 slides backward. At this time, the mesh plate 4 can protect the side of the hanging basket 1 away from the bridge to prevent the sliding debris from falling and injuring the construction workers.
[0041] Working principle: The trolley lowers the hanging basket 1 to one side of the bridge through the hanger 2, and the baffle 31 is abutted against the limit block 21 by the contraction of the second servo electric cylinder 38. At this time, the baffle 31 can cover the top of the hanging basket 1, and then the extension plate 34 is horizontally extended by the extension of the first servo electric cylinder 35, and abuts against the side wall of the bridge. At this time, the construction above is protected by the extension plate 34 and the baffle 31. When it is necessary to lower tools or materials in the hanging basket 1, the second servo electric cylinder 38 is extended and the baffle 31 is flipped upward counterclockwise with the shaft 32 as the axis. At this time, the top of the hanging basket 1 is open to facilitate lifting. After the lifting is completed, the baffle 31 is reset by the contraction of the second servo electric cylinder 38.
