DETAILED DESCRIPTION
[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:
[0026] like Figure 1 , 2 As shown, a highway guardrail installation machine includes a road tow truck 1, the road tow truck 1 is equipped with a crane 3, the arm 13 of the crane 3 is equipped with a clamp device 4, the clamp device 4 includes a flip frame 16, the flip frame 16 is arranged in a gantry bracket, the top of the flip frame 16 is connected to the arm 13 through a rotating cylinder 15, and the lower two sides of the flip frame 16 are hingedly provided with clamps 18 that can clamp the corrugated guardrail 27.
[0027] like Figure 2 , 3 As shown in Figure 4, the top of the rotating cylinder 15 is hinged and fixed to the connecting piece 14 installed on the small arm 13. The connection of the connecting piece 14 can ensure that the lower rotating cylinder 15 always maintains a vertical state when the height of the small arm 13 changes up and down, and the rotating cylinder 15 itself will not rotate. The bottom of the rotating axis of the rotating cylinder 15 is connected and fixed to the turning frame 16. The two sides of the turning frame 16 are provided with a turning cylinder 17 that drives the clamp 18 and rotates it to a certain angle. The angle of the clamp 18 is adjusted by changing the extended length of the turning cylinder (the clamp 18 can be turned 90°). The piston rod of the turning cylinder 17 is hinged and fixed to the upper side end of the clamp 18 through a connecting rod 171. The transition connection through the connecting rod 171 can make the clamp 18 turn 90 degrees in a vertical state. The turning cylinder 17 will not interfere with the turning frame 16.
[0028] like Figure 5 As shown, the clamp 18 includes two connecting side plates 19 connected by multiple pins 20, and downwardly extending clamps 24 are hinged on both sides of the two connecting side plates 19. The clamps 24 are driven and connected by clamping cylinders 25 arranged in the two connecting side plates 19. The corrugated guardrail plate 27 can be clamped and fixed by driving the clamps 24 to flip through the clamping cylinders 25.
[0029] like Figure 5 As shown, the lower part of the two connecting side plates 19 of the clamp 18 is provided with a magnetic support component for pre-fixing the corrugated guardrail plate 27. The corrugated guardrail plate 27 can be lifted and pre-fixed by the electromagnet attraction of the magnetic support component.
[0030] like Figure 5 As shown, the magnetic support assembly includes two support wheels 22 supported by the grooves of the corrugated guardrail plate 27, the support wheels 22 not only support the corrugated guardrail plate 2, but also protect the electromagnet 23, to prevent the electromagnet 23 from adsorbing the corrugated guardrail plate 2 and causing a rigid collision with the electromagnet 23, thereby extending the service life of the electromagnet 23. At the same time, when the subsequent clamping plate 24 clamps the corrugated guardrail plate 2, its local position will change, and the support wheel 22 plays a guiding role. Each support wheel 22 is rotatably connected to the extension protrusion 21 integrally arranged downwardly on the two connecting side plates 19, and the electromagnet 23 is fixed on the outer side of the extension protrusion 21.
[0031] like Figure 5 As shown, a clamping block 26 for clamping the outer end of the corrugated guardrail plate 27 is provided on the inner side of the clamping plate 24. The clamping block 26 is an L-shaped rubber block. The rubber block has a buffering effect to prevent the corrugated guardrail plate 27 from being squeezed and deformed when clamped. The L-shape can clamp the corrugated guardrail plate 27 to prevent it from falling off when clamped.
[0032] like Figure 2 As shown, the crane 3 includes a crossbeam 6 fixed on the front end automobile beam 5 of the carriage 2 of the road tow truck 1, a hydraulically driven rotator 8 is fixed on the upper part of the crossbeam 6, the rotator 8 adopts a hydraulic motor to drive the rotating gear to rotate, and the rotator 8 can drive the part above the crossbeam to rotate 360°, the upper part of the rotator 8 is hinged and fixed to the main arm 11 through the column 9, the main arm 11 is driven and connected by the variable-length oil cylinder 10 installed on the side of the column 9, and the height adjustment is achieved by adjusting the angle of the main arm 11 by changing the telescopic length of the variable-length oil cylinder 10, the front end of the main arm 11 is hinged with a small arm 13, the front end of the small arm 13 is installed with a hook 131, the small arm 13 is driven and connected by the folding oil cylinder 12 installed at the lower part of the main arm 11, and the angle of the small arm is adjusted by changing the telescopic length of the folding oil cylinder 12 to adjust the position of the clamp device 4.
[0033] like Figure 2As shown, a hydraulic leg 7 that can be extended by a telescopic cylinder is provided in the crossbeam 6 . The hydraulic leg 7 can be extended to improve the stability of the road tow truck 1 in lifting goods and installing the corrugated guardrail plate 27 .
[0034] like Figure 6 As shown, it also includes a hydraulic control system, which includes a hydraulic pump 28, which is driven by the power take-off of the automobile gearbox to achieve the completion of various actions of the device. The hydraulic pump 28 is connected to the hydraulic outrigger 7 and its telescopic cylinder drive, the slewing device 8, the variable amplitude cylinder 10, the folding cylinder 12, the rotating cylinder 15, the flip cylinder 17 and the clamping cylinder 25 through multiple oil pipes, and corresponding hydraulic control valves 29 are installed on the multiple oil pipes. The multiple hydraulic control valves 29 can be wirelessly controlled and connected through a wireless remote controller 30, and the control and driving operation through the wireless remote controller 30 is more convenient.
[0035] like Figure 7 As shown, the electromagnet 23 is electrically connected to a battery 31 installed on the road tow truck 1 through a cable, and a wireless control switch 32 is installed on the cable, and the wireless control switch 32 is wirelessly controlled and connected to the wireless remote controller 30.
[0036] The implementation principle of a highway guardrail installation machine in the embodiment of the present application is:
[0037] When transporting the corrugated guardrail 27, operate the hydraulic legs 7 extending out of the crossbeam 6 and firmly support the road tow truck 1, use straps or wire ropes to tie up the multiple corrugated guardrails 27 placed on the ground, operate the wireless remote controller 30 to control the rotator 8 and retract the variable-length cylinder 10 to lower the hook 131 on the forearm 13 of the crane 3 to connect with the strap (operate the rotating cylinder 15 to the corresponding position when lifting materials to avoid interference between the clamp device 4 and the hook 131), operate the rotator 8 and retract and extend the variable-length cylinder 10 to lift the corrugated guardrail 27 hung on the strap and place it on the upper part of the carriage 2 of the road tow truck 1, so as to realize the lifting and transport of the corrugated guardrail 27 on site;
[0038] When the corrugated guardrail plate 27 is transported to the corresponding position of the road for installation, the slewing device 8, the luffing cylinder 10 and the folding cylinder 12 on the crane 3 are operated to make the clamp device 4 on the forearm 13 of the crane 3 face the corrugated guardrail plate 27 on the carriage 2, and the rotating cylinder 15 is continued to be operated to make the supporting wheels 22 of the two clamps 18 at the lower part of the turning frame 16 face the corresponding grooves of the corrugated guardrail plate 27, and the luffing cylinder 10 is operated to lower the two clamps 18 and close to the corrugated guardrail plate 27, thereby simultaneously controlling the wireless remote control 30 to control the The wireless control switch 32 is turned on to energize the electromagnet 23 on the fixture 18. When the corrugated guardrail plate 27 is approaching, the magnetic attraction of the electromagnet 23 causes the lower corrugated guardrail plate 27 to be adsorbed and moved upward to contact the two support wheels 22. At the same time, the electromagnet 23 and the corrugated guardrail plate 27 are fitted to pre-fix the corrugated guardrail plate 27. After fitting, the clamping cylinders 25 extending from both sides of the fixture 18 are operated to flip the clamping plates 24 to clamp the two side ends of the corrugated guardrail plate 27, thereby clamping and fixing the corrugated guardrail plate 27.
[0039] After clamping and fixing, the slewing device 8, the boom cylinder 10 and the folding cylinder 12 of the crane 3 and the rotating cylinder 15 of the clamp device 4 are operated to move the clamped corrugated guardrail board 27 to the column on the side of the road. At the same time, the flipping cylinder 17 on the clamp device 4 is operated. The piston rod of the flipping cylinder 17 flips the fixture 18 90 degrees through the connecting rod 171, so that the corrugated guardrail board 27 is vertical as a whole and fits with the column installed on the side of the road. After fitting, the operator uses bolts to install and fix the corrugated guardrail board 27. After fixing, the electromagnet 23 is powered off to loosen the clamp 24 of the fixture 18, and the road tow truck 1 is continued to move forward to operate and install the remaining corrugated guardrail boards 27. During installation, the hydraulic support legs 7 can be extended for support according to the on-site conditions.
[0040] The utility model installs the clamp device fixed on the crane and its forearm on the automobile beam 5 at the front end of the carriage 2 of the road tow truck 1, and controls the operation through the hydraulic control system, so that the corrugated guardrail plate 27 can be installed at various angles, which can meet various complex working conditions; the operation range is wide, and the crane arm adopts a two-section arm main arm 11 and a forearm 13 folding structure, which can complete long-distance and short-distance operations (maximum operation radius 4m); and it can be used for multiple purposes, and a hook 131 is provided on the fixed arm forearm 13, which can lift heavy objects; at the same time, the clamp is flexible and has a magnetic support component, and the clamp device 4 can realize the XYZ three-axis rotation function, thereby improving the operation efficiency; in this way, the efficiency of installing and transporting the corrugated guardrail plate 27 is doubled, which greatly saves labor costs, and fundamentally eliminates the occurrence of safety accidents caused by manual transportation and installation of the corrugated guardrail plate 27.
