Technical Field

[0001] The utility model relates to a self-propelled hydraulic trolley for cast-in-situ anti-collision guardrails of bridges, belonging to the field of road construction equipment. Background Art

[0002] With the rapid development of the transportation infrastructure industry, bridges, as an important part of transportation routes, play an irreplaceable role. A viaduct generally refers to a bridge that crosses a road in an urban area or a highway bridge that crosses land in the wild. Therefore, crash barriers are an important part of viaducts. With the improvement of construction technology, the use of a guardrail construction trolley for crash barrier installation is currently the most efficient construction method.

[0003] However, traditional guardrail construction trolleys can only perform single-sided construction, and the hanging basket structure used by workers to adjust the template is inconvenient, resulting in low construction efficiency. In addition, counterweights need to be set on the guardrail construction trolley to prevent it from tipping over, which requires the driving guardrail construction trolley to carry invalid loads, resulting in excessively high costs.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0025] Please refer to Figures 1 to 2, an embodiment of the present application shows a self-propelled hydraulic trolley for cast-in-situ anti-collision guardrails for bridges (hereinafter referred to as "self-propelled hydraulic trolley"), which includes a moving mechanism, a lifting mechanism and a hanging basket mechanism 20.

[0026] The moving mechanism includes a trolley frame 11 and a self-moving component 12 arranged at the bottom of the trolley frame 11. The self-moving component 12 drives the trolley frame 11 to move, wherein the self-moving component 12 includes a moving wheel arranged at the bottom of the trolley frame 11 and a driving motor that drives the moving wheel to rotate.

[0027] In one embodiment, the self-propelled hydraulic trolley further includes a positioning assembly (not shown) provided at the bottom of the trolley frame 11. The positioning assembly includes a hydraulic cylinder and a positioning plate provided on the output shaft of the hydraulic cylinder. The positioning plate is abutted against the bridge deck under the drive of the hydraulic cylinder to separate the self-moving assembly 12 from the bridge deck. The hydraulic cylinder is arranged in a vertical direction, and the output shaft is directed toward the bridge deck. The positioning plate is arranged parallel to the front. During the movement of the self-propelled hydraulic trolley, the hydraulic cylinder contracts to move the positioning plate away from the bridge deck. After the self-propelled hydraulic trolley reaches a specified position during movement, the output shaft of the hydraulic cylinder is extended to move the positioning plate toward the bridge deck. Under the action of the reaction force, the self-propelled hydraulic trolley is lifted up to separate the moving wheels from the ground. The positioning is performed by the positioning plate to prevent the self-propelled hydraulic trolley from moving.

[0028] The hoisting mechanism is symmetrically arranged on both sides of the trolley frame 11, and is used to hoist the anti-collision guardrail template. The hoisting mechanism includes a vertical drive component 31, a horizontal drive component 32 arranged on the vertical drive component 31, and a hoisting component 33 arranged on the horizontal drive component 32. The hoisting component 33 is used to drive the anti-collision guardrail template to rise or fall. Among them, the hoisting component 33 includes a sling 332 for hanging the anti-collision guardrail template and a hanging jack 331 connected between the sling 332 and the horizontal drive component 32. The vertical drive component 31 and the hanging jack 331 cooperate to realize the two-level lifting of the anti-collision guardrail template in the vertical direction, which can effectively reduce the height requirement of the trolley frame 11, make the structure more stable, and save more materials. The hoisting component 33 is driven by the horizontal drive component 32 to drive the anti-collision guardrail template to move in the horizontal direction, thereby meeting the hoisting requirements of the anti-collision guardrail template.

[0029] The vertical drive assembly 31 includes a cantilever beam 311 that slides vertically with the trolley frame 11 and a power member 312 that drives the cantilever beam 311. The longitudinal direction of the cantilever beam 311 extends away from the trolley frame 11. The power member 312 is a hydraulic cylinder, a hydraulic jack, etc. The cantilever beam 311 is mounted on the vertical support beam of the trolley frame 11 and is driven by the power member 312 to slide up and down on the vertical support beam.

[0030] The horizontal driving component 32 includes a node box 321 that slidably cooperates with the cantilever beam 311 in the horizontal direction, and a driving member 322 that drives the node box 321 to move closer to or away from the bogie frame 11. The hoisting component 33 is arranged on the node box 321. Specifically, the driving member 322 is a hydraulic cylinder, a hydraulic jack, etc. The cantilever beam 311 is T-shaped. The short arm of the T-shaped cantilever beam 311 is slidably mated with the bogie frame 11 in the vertical direction. The node box 321 is sleeved on the long arm of the T-shaped cantilever beam 311, and the driving member 322 drives the node box 321 to move horizontally on the long arm of the T-shaped cantilever beam 3,11.

[0031] In other embodiments, the sliding connection structures between the cantilever beam 311 and the bogie frame 11 and between the node box 321 and the cantilever beam 311 can also be a sliding structure similar to a gantry. One of them is a convex structure, and the other is wrapped around the convex structure and connected by bearings.

[0032] The hanging basket mechanism 20 includes a hanging basket platform 22 and a lifting driving member 21 connected between the hanging basket platform 22 and the hoisting mechanism. The lifting driving member 21 is arranged at the outermost end of the long arm of the T-shaped cantilever beam 311. The hanging basket platform 22 includes a bottom plate and a guard net surrounding the periphery of the bottom plate. The lifting driving member 21 is an electric hoist. The electric hoist can control the lifting of the hanging basket platform 22 to meet the construction requirements of workers at any position in the height direction.

[0033] The self-propelled hydraulic trolley further includes a passage component arranged between the bogie frame 11 and the hanging basket component. The passage component is used for construction workers to reach or leave the hanging basket platform 22.

[0034] The passage component includes a first climbing ladder 41 arranged on the bogie frame 11 in the vertical direction, a walking passage 43 arranged on the cantilever beam 311, and a second climbing ladder 44 connected between the cantilever beam 311 and the hanging basket platform 22. The walking passage 43 is connected to or disconnected from the first climbing ladder 41 under the action of the vertical driving component 31. The top of the first climbing ladder 41 is fixed on the bogie frame 11, and the other end is close to the bridge deck. The top of the second climbing ladder 44 is fixed at the outermost end of the long arm of the T-shaped cantilever beam 311, and the other end penetrates through the bottom plate of the hanging basket platform 22. The walking passage 43 is a U-shaped structure with an upward opening. One end of it is connected to the cantilever beam 311, and the other end is close to the top of the second climbing ladder 44. When workers go up and down, the power member 312 drives the cantilever beam 311 to move to a suitable height so that the walking passage 43 connects the first climbing ladder 41 and the second climbing ladder 44, enabling workers to pass between the bridge deck and the hanging basket platform 22. When workers are required to cooperate in installing the anti-collision guardrail template, it reduces the difficulty for workers to reach the hanging basket platform 22. When workers do not need to work at a high altitude, the self-propelled hydraulic trolley does not need to be moved, allowing workers to get off the hanging basket platform 22, which is safer and avoids affecting the construction progress.

[0035] The passage assembly also includes a connecting ladder 42 disposed between the trolley frame 11 and the walking channel 43. One end of the connecting ladder 42 is hinged to the trolley frame 11, and the other end is slidably connected to the upper surface of the walking channel 43. The hinged end of the connecting ladder 42 is connected to the first climbing ladder 41, and the other end is slidably connected to the upper surface of the walking channel 43. This ensures that the entire passage assembly is connected at any height of the cantilever beam 311, reducing the process of adjusting the connection of the passage assembly and increasing convenience.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
