Description

Technical Field

[0001] The utility model relates to the technical field of highway corrugated guardrail construction equipment, and more particularly to a boom adjustment mechanism for a highway corrugated guardrail installation trolley. Background Art

[0002] Expressways are developing rapidly, and the mileage of roads in operation continues to increase. Driving safety and protective facilities are becoming increasingly important to travel safety. Corrugated steel guardrails are a crucial line of defense for life safety, and they are currently the most important and effective protective guardrails on expressways. To prevent rust during use, these guardrails are galvanized before leaving the factory, ensuring both protection and aesthetics.

[0003] During the actual installation of the corrugated guardrail, several columns are driven vertically with an impact drill and fixed to the road surface by means of explosive screws. Then the column caps are installed, and the connectors are fixed to the column bodies with bolts. Finally, all the corrugated guardrails are laid out along the arrangement direction of the columns. The inclination direction of the corrugated guardrail needs to effectively guide the out-of-control vehicle to reduce the probability of accidents. Then all the corrugated guardrails and the connectors are bent and fixed in turn. In the existing technology, the stacked corrugated guardrails are generally hoisted from the truck by a trolley, and the heavier corrugated guardrails are hoisted to the side installation positions of several columns in turn. The trolley hoisting boom is difficult to flexibly adjust according to the inclination installation angle and height of the corrugated guardrail, resulting in low construction efficiency. At the same time, during the hoisting process, adjacent corrugated guardrails are prone to collision, resulting in damage to the galvanizing, which affects the construction quality.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further explained below with reference to specific illustrations.

[0020] In order to solve the problem that the existing trolley hoisting boom is difficult to flexibly adjust according to the tilt installation angle and height of the corrugated guardrail, resulting in low construction efficiency, and at the same time, during the hoisting process, adjacent corrugated guardrails are prone to collision, resulting in damage to the galvanized steel and affecting the construction quality, such as Figure 1 As shown, the present application includes a trolley frame 1, and the trolley frame 1 is provided with traveling wheels 2 at the four corner positions. Both sides of the upper surface of the trolley frame 1 are connected upward with vertical bracket plates 3, and a mounting plate 4 is set between the vertical bracket plates 3. A plurality of hydraulic telescopic top columns 5 are provided on the surface of the mounting plate 4. The upper end telescopic sections of the plurality of hydraulic telescopic top columns 5 are respectively connected to the intersection of the horizontal and vertical brackets of the grid bracket 6. The grid bracket 6 is composed of a plurality of horizontal and vertical brackets of different lengths. A circular track 7 is welded and fixed to the lower side of the outer periphery of the grid bracket 6, and a plurality of booms 8 are slidably mounted on the track 7;

[0021] like Figure 3 As shown, the vertical support plate 3 is located below the hollow position of the grid support 6 and does not affect the lifting and lowering of the grid support 6 and the track 7;

[0022] like Figure 2 As shown, triangular reinforcing ribs 10 are provided at the intersections of the vertical bracket plate 3 and the mounting plate 4 on both sides, and triangular reinforcing ribs are provided at the intersections of the vertical bracket plate 3 and the trolley frame 1 to improve the overall strength and stability of the bracket;

[0023] The upper surface of the trolley frame 1 is also provided with a power supply box 11, a controller 13 and a drive motor 12. A hydraulic cylinder 14 is fixed to the lower surface of the mounting plate 4.
