Description

When a vehicle collides with the corrugated beam guardrail, it can prevent the vehicle from running off the road, thereby protecting the safety of the vehicle and passengers.

DETAILED DESCRIPTION

[0039] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various forms, so the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components that are not connected with the invention will be omitted from the drawings.

[0040] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0041] Embodiment 1:

[0042] This embodiment introduces a specific structure of a corrugated beam guardrail installation device, such as Figure 1-Figure 13 As shown, including:

[0043] A vehicle body 1, a cantilever assembly 2 is installed above the vehicle body 1, the cantilever assembly 2 is composed of a column 21, a cross beam 22 and a movable arm 23, the left end of the cross beam 22 is horizontally rotatably connected to the column 21, the top end of the movable arm 23 is vertically rotatably connected to the right end of the cross beam 22, and the bottom of the movable arm 23 is rotatably connected to a control column 3;

[0044] The installation component is arranged on the control column 3. The installation component is composed of a main control frame 4 and auxiliary control frames 5 arranged on both sides of the main control frame 4. The installation component adopts a three-stage control frame structure. During the construction process, it is convenient to make the guardrail plate bend under pressure, so as to facilitate the installation work on the curved road section. The main control frame 4 is welded and fixed to the control column 3. The auxiliary control frame 5 is rotatably connected to the end of the main control frame 4. A control mechanism is arranged between the auxiliary control frame 5 and the control column 3. The control mechanism includes a pushing block 53, a slider 55 and a push plate 56, which is used to push the auxiliary control frame 5 to rotate at the end of the main control frame 4 and make the guardrail plate bend under pressure;

[0045] The clamping assembly is arranged at the upper and lower edges of the main control frame 4 and the auxiliary control frame 5. The clamping assembly consists of a clamping frame 6 that is symmetrical in upper and lower directions. The two ends of the clamping frame 6 are connected to a third hydraulic cylinder 63. The third hydraulic cylinder 63 can control the clamping frame 6 so that the clamping assembly can grab and clamp the corrugated beam guardrail plate. An array of conical wheels 66 are arranged on the side of the clamping frame 6 away from the control column 3. The arrangement of the conical wheels 66 can improve the fitting effect between the clamping frame 6 and the curved surface of the corrugated beam guardrail plate.

[0046] When installing the corrugated beam guardrail, the upright column 21, the cross beam 22 and the movable arm 23 cooperate with each other to drive the control column 3 to move, and the control column 3 drives the installation component to move, thereby facilitating the installation component and the clamping component to grab and install the corrugated beam guardrail.

[0047] When installing along a straight section, the auxiliary control frame 5 is fitted with the control column 3, and the main control frame 4 and the control column 3 are on the same center line. At this time, the main control frame 4 and the auxiliary control frame 5 cooperate with each other to grab the corrugated beam guardrail on the freight vehicle and install the corrugated beam guardrail along the construction route.

[0048] When installing along a curved section, since the installation assembly is composed of a three-section main control frame 4 and an auxiliary control frame 5, the push block 53, the slider 55 and the push plate 56 can cooperate with each other according to the curvature of the road, and push the auxiliary control frame 5 to rotate at the end of the main control frame 4. The auxiliary control frame 5 and the extrusion wheel 82 cooperate with each other to continuously squeeze the guardrail plate so that the guardrail plate is compressed and bent, thereby facilitating the installation of the guardrail plate along the curved section and reducing the labor cost during installation.

[0049] like Figure 3 As shown, a base 211 is provided at the bottom of the column 21. The setting of the base 211 can install the cantilever assembly as a whole on a construction vehicle or other vehicle body, so that the installation device can install the guardrail along the construction road. A hydraulic lifting column 212 is provided on the inner side of the column 21. The hydraulic lifting column 212 slides up and down along the column 21. A rotating seat 221 is provided at the left end of the beam 22. A rotating motor is installed inside the rotating seat 221. The beam 22 is horizontally connected to the top of the hydraulic lifting column 212 through the rotating motor inside the rotating seat 221. A first hydraulic cylinder 24 is installed between the movable arm 23 and the beam 22. The two ends of the first hydraulic cylinder 24 are respectively connected to the movable arm 23 and the beam 22 for rotation, so as to push the top end of the movable arm 23 to rotate vertically on the beam 22.

[0050] When the hydraulic lifting column 212 is in operation, it can drive the cross beam 22 and the movable arm 23 to move up and down, thereby adjusting the height of the installation component. When the first hydraulic cylinder 24 is in operation, it pushes the top end of the movable arm 23 to rotate vertically on the cross beam 22, so that the movable arm 23 drives the control column 3 to move further, and the outward extension distance of the control column 3 can be controlled, so that the installation component on the control column 3 can grab or install the guardrail plate.

[0051] like Figure 3 and Figure 6 As shown, a connecting seat 31 is provided at the center of the control column 3, and the bottom end of the movable arm 23 is rotatably connected to the connecting seat 31. An adjusting block 42 is welded and fixed on one side of the main control frame 4 close to the movable arm 23. A second hydraulic cylinder 25 is provided between the adjusting block 42 and the movable arm 23. The cylinder body of the second hydraulic cylinder 25 is rotatably connected to the movable arm 23, and the piston rod of the second hydraulic cylinder 25 is rotatably connected to the adjusting block 42.

[0052] When the second hydraulic cylinder 25 is running, pressure can be applied to the adjustment block 42 through the piston rod, and the connecting seat 31 can be rotated at the bottom end of the movable arm 23, so as to adjust the direction of the installation assembly. When the second hydraulic cylinder 25 contracts, the main control frame 4 and the auxiliary control frame 5 are in a vertical state, and the guardrail plate can be limited by the clamping frame 6 to facilitate the installation of the guardrail plate along the construction route. When the second hydraulic cylinder 25 extends outward, the main control frame 4 and the auxiliary control frame 5 can be adjusted to a horizontal state. At this time, the main control frame 4 and the auxiliary control frame 5 are moved to the top of the freight vehicle, and the corrugated beam guardrail plate can be grabbed to the bottom of the main control frame 4 and the auxiliary control frame 5 through the clamping assembly.

[0053] like Figure 4-Figure 6 As shown, connecting frames 41 are provided at both ends of the main control frame 4, and the connecting frames 41 and the main control frame 4 are integrally formed. A movable frame 51 is provided on the auxiliary control frame 5 and on one side close to the main control frame 4, and the movable frame 51 and the auxiliary control frame 5 are integrally formed. The auxiliary control frame 5 is rotatably connected with the connecting frame 41 through the movable frame 51, so that the auxiliary control frame 5 can rotate on the main control frame 4, and can squeeze the clamped corrugated beam guardrail plate, so that the corrugated beam guardrail plate is compressed and bent, so as to facilitate installation on curved sections. On the side wall of the auxiliary control frame 5 and on the outside of the control column 3, there are welded and fixed limit plates 52 symmetrically distributed up and down, and the limit plates 52 are snap-fitted with the control column 3. When the main control frame 4 and the auxiliary control frame 5 are on the same center line, the limit plates 52 and the control column 3 are snap-fitted and fixed, which can improve the stability between the control column 3 and the auxiliary control frame 5.

[0054] like Figure 7-Figure 9 As shown, both ends of the control column 3 are provided with a storage cavity 32, and the storage cavity 32 is arranged on the outside of the auxiliary control frame 5. A threaded rod 54 is installed on the inside of the storage cavity 32, and the end of the threaded rod 54 is rotatably connected to the side wall of the storage cavity 32. The pushing block 53 is arranged between the limit plates 52 on the upper and lower sides and is welded and fixed to the auxiliary control frame 5. The slider 55 is slidably arranged on the inside of the storage cavity 32 and is threadedly connected to the threaded rod 54. The push plate 56 is arranged between the push block 53 and the slider 55, and the two ends are rotatably connected to the push block 53 and the push plate 56 respectively. A cavity 33 is provided on the control column 3 and near the storage cavity 32. A motor 57 for driving the threaded rod 54 to rotate is installed on the inside of the cavity 33. The auxiliary control frame 5 is controlled by the cooperation between the threaded rod 54 and the motor 57, so that the rotation control angle of the auxiliary control frame 5 has a higher accuracy.

[0055] When the motor 57 runs to drive the threaded rod 54 to rotate, the threaded rod 54 and the slider 55 rotate relative to each other, which can drive the slider 55 to slide along the storage cavity 32, so that the slider 55 squeezes the push plate 56. At the same time, the two ends of the push plate 56 rotate on the push block 53 and the push plate 56 respectively, and squeeze the auxiliary control frame 5 through the push block 53, so that the movable frame 51 rotates on the connecting frame 41, thereby squeezing the clamped corrugated beam guardrail through the auxiliary control frame 5, so that the corrugated beam guardrail is compressed and bent, so as to facilitate installation on curved sections and reduce the labor cost during installation.

[0056] like Figure 10-11 As shown, a connecting block 61 is provided on the clamping frame 6 and on one side close to the mounting assembly, and the clamping frame 6 is rotatably connected to the edges of the main control frame 4 and the auxiliary control frame 5 through the connecting block 61, and symmetrically distributed driving frames 62 are provided at both ends of the clamping frame 6 and on one side close to the control column 3, and the driving frame 62 and the clamping frame 6 are integrally formed, and the piston rod of the third hydraulic cylinder 63 is rotatably connected to the driving frame 62, and mounting blocks 631 are welded and fixed on the main control frame 4 and the auxiliary control frame 5 and close to the third hydraulic cylinder 63, and the cylinder body of the third hydraulic cylinder 63 is rotatably connected to the mounting block 631.

[0057] When the third hydraulic cylinder 63 is running, the cylinder body of the third hydraulic cylinder 63 rotates on the mounting block 631, and the piston rod of the third hydraulic cylinder 63 rotates on the driving frame 62, and applies pressure to the clamping frame 6, so that the clamping frame 6 rotates around the connecting block 61, thereby facilitating the clamping frame 6 to clamp the corrugated beam guardrail plate.

[0058] A strip groove 64 is provided on the clamping frame 6 on the side away from the control column 3, and an array of mounting shafts 65 are provided on the inner side of the strip groove 64. Each conical wheel 66 is respectively provided on the mounting shaft 65 and is rotatably connected to the mounting shaft 65. The side surface of the conical wheel 66 close to the third hydraulic cylinder 63 is a conical structure, so that the conical wheel 66 has a good contact effect with the surface of the corrugated beam guardrail.

[0059] When the auxiliary control frame 5 squeezes the corrugated beam guardrail plate and causes the corrugated beam guardrail plate to bend under pressure, and the clamping frame 6 is slightly loosened, during the squeezing process, the conical wheel 66 can roll along the surface of the corrugated beam guardrail plate and apply uniform pressure on the other side of the corrugated beam guardrail plate, thereby improving the bending forming effect of the guardrail plate.

[0060] In addition, during the installation of the guardrail, after one end of the guardrail is fixed, the vehicle body 1 is moved along the construction route, and the conical wheel 66 can be used to limit and guide the outer side of the corrugated beam guardrail, thereby ensuring the clamping effect while allowing the main control frame 4 and the auxiliary control frame 5 to move along the corrugated beam guardrail, so that the main control frame 4 and the auxiliary control frame 5 can cooperate with each other to control the curvature of the corrugated beam guardrail.

[0061] Working principle: First, operate the second hydraulic cylinder 25 to push the control column 3 to rotate at the bottom of the movable arm 23, and adjust the main control frame 4 and the auxiliary control frame 5 to a horizontal state. Then, by controlling the hydraulic lifting column 212, the crossbeam 22 and the movable arm 23, the movable arm 23 drives the control column 3 to move, and moves the main control frame 4 and the auxiliary control frame 5 to the top of the corrugated beam guardrail. Then, operate the hydraulic lifting column 212 to drive the control column 3 to move downward, so that the main control frame 4 and the auxiliary control frame 5 are in contact with the corrugated beam guardrail. Then, operate the third hydraulic cylinder 63 to push the clamping frame 6 to rotate around the connecting block 61 and clamp the corrugated beam guardrail.

[0062] Further, the second hydraulic cylinder 25 is operated to adjust the main control frame 4 and the auxiliary control frame 5 to a vertical state, and then, by controlling the hydraulic lifting column 212, the crossbeam 22 and the movable arm 23, the control column 3 drives the installation assembly and the corrugated beam guardrail plate to the installation position, and the main control frame 4, the auxiliary control frame 5 and the clamping frame 6 cooperate with each other to suspend and fix the corrugated beam guardrail plate, so as to facilitate the installation of the corrugated beam guardrail plate on the guardrail column;

[0063] When construction is carried out along a curved section and the corrugated beam guardrail plate needs to be bent, the clamping frame 6 is controlled to be slightly loosened by the third hydraulic cylinder 63, so that the motor 57 can be turned to drive the threaded rod 54 to rotate, and the threaded rod 54 and the slider 55 can rotate relative to each other, so that the slider 55 squeezes the push plate 56, and the auxiliary control frame 5 is pushed by the push plate 56 to rotate at the end of the main control frame 4, so that the auxiliary control frame 5 squeezes the clamped corrugated beam guardrail plate. At the same time, the conical wheel 66 can roll along the surface of the corrugated beam guardrail plate, and evenly pressurize the other side of the corrugated beam guardrail plate, so that the corrugated beam guardrail plate is compressed and bent, so as to facilitate installation on the curved section.

[0064] Embodiment 2:

[0065] This embodiment is an improvement based on the first embodiment:

[0066] In order to further improve the bending effect of the corrugated beam guardrail during the construction process, an adjustment cavity 7 is provided on the main control frame 4 and the auxiliary control frame 5 near the center, and an array of arc-shaped concave wheels 72 are provided on the inner side of the adjustment cavity 7. At the same time, an extrusion mechanism is installed on the auxiliary control frame 5 away from the main control frame 4, and the extrusion mechanism includes a mounting frame 8, a rotating frame 81 and an extrusion wheel 82.

[0067] like Fig.12As shown, both ends of the arc-shaped concave wheel 72 are provided with an integrally formed movable shaft 73, and the arc-shaped concave wheel 72 is rotatably connected to the adjustment chamber 7 through the movable shaft 73. The surface of the arc-shaped concave wheel 72 is an arc-shaped concave surface, and the arc-shaped concave surface fits the curved surface of the guardrail plate, which can improve the guiding and limiting effects of the corrugated beam guardrail plate.

[0068] When the vehicle body 1 moves along the construction route, multiple curved concave wheels 72 cooperate with the conical wheels 66 to provide limited guidance on both sides of the corrugated beam guardrail plate, thereby improving the stability of the main control frame 4 and the auxiliary control frame 5 when moving along the corrugated beam guardrail plate. When the corrugated beam guardrail plate is bent, the curved concave wheels 72 can be used to roll and squeeze the corrugated beam guardrail plate on the inner side of the main control frame 4 and the auxiliary control frame 5 to improve the smoothness of the corrugated beam guardrail plate when bending and avoid excessive local bending of the corrugated beam guardrail plate.

[0069] An array of slide grooves 71 are provided on the upper and lower inner walls of the adjustment chamber 7, and an integrally formed movable shaft 73 is provided at both ends of the arc surface concave wheel 72. The movable shaft 73 is movably connected to the slide groove 71. When the corrugated beam guardrail is bent along a curved section, the arc surface concave wheel 72 can slide and rotate in the slide groove 71 at the same time through the movable shaft 73, so that the arc surface concave wheel 72 can move freely, and according to the compression and bending condition of the corrugated beam guardrail, the spacing of the arc surface concave wheel 72 can be freely changed to ensure that the corrugated beam guardrail has a good bending effect.

[0070] like Fig.13 As shown, the mounting frame 8 is welded and fixed to the end of the auxiliary control frame 5, and the rotating frame 81 is arranged on the side close to the auxiliary control frame 5. One side of the rotating frame 81 is rotatably connected to the mounting frame 8 through a rotating shaft, and an extrusion wheel 82 is installed on the other side of the rotating frame 81. The extrusion wheel 82 is rotatably connected to the end of the rotating frame 81. The surface of the extrusion wheel 82 is an arc-shaped concave surface, and the arc-shaped concave surface fits the curved surface of the guardrail plate, so that the extrusion wheel 82 has a good contact effect with the surface of the corrugated beam guardrail plate.

[0071] A connecting rod 83 is welded and fixed on the inner side of the rotating frame 81 and close to the extrusion wheel 82. A fourth hydraulic cylinder 84 is arranged between the connecting rod 83 and the mounting frame 8. The cylinder body of the fourth hydraulic cylinder 84 is rotatably connected to the mounting frame 8. The piston rod of the fourth hydraulic cylinder 84 is rotatably connected to the connecting rod 83, and is used to push the rotating frame 81 to rotate on the mounting frame 8.

[0072] When the corrugated beam guardrail plate is extruded and bent, the fourth hydraulic cylinder 84 is operated, the cylinder body of the fourth hydraulic cylinder 84 rotates on the mounting frame 8, the piston rod of the fourth hydraulic cylinder 84 rotates on the connecting rod 83, and pushes the rotating frame 81 to rotate on the mounting frame 8, so that the rotating frame 81 drives the extrusion wheel 82 to approach the corrugated beam guardrail plate, and further extrude the corrugated beam guardrail plate through the corrugated beam guardrail plate on the outside of the auxiliary control frame 5, thereby improving the compressive bending effect of the corrugated beam guardrail plate. In addition, during the extrusion process, the extrusion wheel 82 can roll along the curved surface of the corrugated beam guardrail plate, thereby avoiding excessive local compression of the corrugated beam guardrail plate and affecting the bending effect.

[0073] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
