[0043] 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.

[0044] 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:

[0045] Embodiment 1:

[0046] This embodiment introduces a specific structure of a fast replacement device for highway guardrails, such as Figure 1-Figure 13As shown, it comprises: a vehicle body 1, a lifting assembly is installed on the vehicle body 1, and the lifting assembly comprises a column 11, a control frame 13 is arranged on the top of the column 11, and two sets of parallel adjustment frames 14 are installed on the inner side of the control frame 13, one end of the adjustment frame 14 is rotatably connected to the control frame 13, and the other end of the adjustment frame 14 is rotatably connected to a lifting seat 15, and a parallelogram structure is formed between the control frame 13, the adjustment frame 14 and the lifting seat 15. Under the action of the control frame 13 and the two sets of adjustment frames 14, the lifting seat 15 is always kept in a vertical state, and a horizontally rotating telescopic arm 2 is arranged on the lifting seat 15, and a telescopic rod 21 is slidably connected to the inner side of the telescopic arm 2;

[0047] The hanging frame 3 is arranged at the end of the telescopic rod 21. The bottom of the hanging frame 3 is rotatably connected with a clamping mechanism. The clamping mechanism includes a clamping plate seat 31, a first clamping plate 32 and a second clamping plate 33. The first clamping plate 32 and the second clamping plate 33 are respectively arranged on both sides of the clamping plate seat 31 and are rotatably connected with the clamping plate seat 31. The inner sides of the first clamping plate 32 and the second clamping plate 33 are both provided with a control cavity 35. The inner side of the control cavity 35 is provided with a fixing mechanism. The fixing mechanism includes a limit plate 4, a first spring 44 and a push block 45. The push block 45 is symmetrically arranged on both sides of the limit plate 4 and pushes the limit plate 4 to slide along the control cavity 35.

[0048] The outer side of the first clamping plate 32 is rotatably connected to a movable arm 5, the end of the movable arm 5 is provided with a storage box 52, the inner side of the storage box 52 is slidably connected to a movable plate 53, and the movable plate 53 is provided with an array-distributed suction cup mechanism, which includes a sleeve 6, a movable column 61 and a suction cup 62.

[0049] During the process of replacing the guardrail panels on the highway, the multiple guardrail panels loaded on the vehicle body 1 can be lifted by cooperating with the clamping plate seat 31, the first clamping plate 32 and the second clamping plate 33. The lifting frame 3 can be driven to rotate and lift through the lifting assembly, so that the lifting frame 3 and the clamping mechanism cooperate with each other to lift the multiple guardrail panels to the edge of the road, thereby improving the unloading efficiency of the guardrail panels.

[0050] Furthermore, during the lifting process of the guardrail board, the limiting plate 4, the first spring 44 and the push block 45 cooperate with each other, so that the fixing mechanism can further fix the guardrail board on the inner side of the first clamping plate 32 and the second clamping plate 33, thereby improving the stability of the guardrail board.

[0051] When installing the guardrail, the clamp seat 31 is rotated to a vertical state. At this time, the first clamp 32 is located above the second clamp 33. The guardrail is driven to the vicinity of the installation position by the lifting frame 3 and the clamping mechanism. Then, the movable arm 5 is rotated, and the suction cup mechanism is driven to the right side of the guardrail. The suction cup mechanism is driven to move by driving the movable plate 53. The suction cup mechanism can absorb a single guardrail and move the guardrail close to the installation position, so that the guardrail can be quickly positioned and installed. Then, the vehicle body 1 is moved forward along the road, which can drive the uninstalled guardrail to move along the installation route, thereby facilitating the installation of multiple guardrails in sequence and facilitating the rapid replacement and installation of highway guardrails.

[0052] like Figure 3-Figure 5 As shown, an accessory box is provided inside the column 11, which can be used to install the control system of the highway guardrail quick replacement device. A first rotating seat 12 for horizontal rotation is provided on the top of the column 11, and the bottom of the control frame 13 is welded and fixed to the first rotating seat 12. An extension arm 16 extending to the right side of the control frame 13 is provided on the upper adjustment frame 14. A first hydraulic cylinder 17 is installed on the right side of the control frame 13 and near the bottom end. The cylinder body of the first hydraulic cylinder 17 is rotatably connected to the control frame 13, and the piston rod of the first hydraulic cylinder 17 is rotatably connected to the bottom of the extension arm 16.

[0053] A second rotating seat 22 connected to the lifting seat 15 is provided at the end of the telescopic arm 2. The second rotating seat 22 rotates horizontally on the lifting seat 15. The telescopic rod 21 is slidably connected to the telescopic arm 2. A third rotating seat 23 connected to the hanging frame 3 is provided at the end of the telescopic rod 21. The top of the hanging frame 3 rotates horizontally between the third rotating seat 23. A second hydraulic cylinder 24 is installed above the hanging frame 3. The end of the piston rod of the second hydraulic cylinder 24 is fixedly connected to the end of the telescopic rod 21.

[0054] The first rotating seat 12, the second rotating seat 22 and the third rotating seat 23 are all equipped with stepper motors, which can control the first rotating seat 12, the second rotating seat 22 and the third rotating seat 23 to rotate accurately. When the first rotating seat 12 rotates, it can drive the control frame 13 and the adjustment frame 14 to rotate horizontally, and make preliminary adjustments to the position of the hanging frame 3. When the first hydraulic cylinder 17 is running, the extension arm 16 can drive one end of the adjustment frame 14 to rotate on the control frame 13, and the other end of the adjustment frame 14 can rotate on the lifting seat 15. When the second rotating seat 22 rotates, the telescopic arm 2 and the telescopic rod 21 can be driven to rotate horizontally, and the hanging frame 3 can be further driven to move horizontally. Afterwards, under the action of the second hydraulic cylinder 24, the telescopic rod 21 is moved along the telescopic arm 2, and the hanging frame 3 can be driven to move. When the third rotating seat 23 rotates, the hanging frame 3 can be driven to rotate, and the position of the guardrail plate in lifting can be adjusted to facilitate the alignment of the guardrail plate with the installation route.

[0055] like Figure 6-Figure 8 When the third hydraulic cylinder 313 is in operation, the movable seat 311 can be driven to rotate on the hanging frame 3 and the direction of the clamping plate seat 31 can be adjusted. When the clamping plate seat 31 is in a horizontal state, the first clamping plate 32 and the second clamping plate 33 are respectively located on the left and right sides of the clamping plate seat 31, which is convenient for clamping and lifting the guardrail plate. When the clamping plate seat 31 is in a vertical state, the first clamping plate 32 and the second clamping plate 33 are respectively located on the upper and lower sides of the clamping plate seat 31, which is convenient for installing and replacing the guardrail plate.

[0056] The top ends of the first clamping plate 32 and the second clamping plate 33 are rotatably connected to the two sides of the clamping plate seat 31 respectively, and the top of the clamping plate seat 31 is symmetrically installed with the fourth hydraulic cylinder 34, wherein the piston rod of the fourth hydraulic cylinder 34 on one side is rotatably connected to the first clamping plate 32, and the piston rod of the fourth hydraulic cylinder 34 on the other side is rotatably connected to the second clamping plate 33. When the two groups of fourth hydraulic cylinders 34 on the top of the clamping plate seat 31 are operated respectively, they can respectively drive the first clamping plate 32 and the second clamping plate 33 to rotate and move, so as to facilitate the cooperation between the first clamping plate 32 and the second clamping plate 33 to clamp and lift multiple guardrail panels.

[0057] The limit plate 4 is slidably connected to the inner wall of the control cavity 35, and the bottom end of the limit plate 4 is provided with an integrally formed fixing block 41, and the bottom ends of the side walls on the opposite sides of the first clamping plate 32 and the second clamping plate 33 are provided with strip grooves 36, and the fixing block 41 is slidably connected to the strip groove 36 and extends to the outside of the strip groove 36. During the clamping and lifting process of the guardrail plate, the fixing block 41 further limits the guardrail plate at the ends of the first clamping plate 32 and the second clamping plate 33, thereby improving the fixing effect of the guardrail plate and effectively preventing the guardrail plate from falling during the lifting process. Three groups of anti-skid pads 42 are provided on the limit plate 4 and above the fixing block 41, and three groups of evenly distributed square grooves 37 are provided above the strip groove 36, and the anti-skid pads 42 extend to the outside of the square groove 37. The anti-skid pads 42 are made of rubber material, which can improve the friction limiting effect of the guardrail plate on the sides of the first clamping plate 32 and the second clamping plate 33, thereby further improving the clamping effect of the guardrail plate.

[0058] Both ends of the limit plate 4 are provided with inclined plane blocks 43, and a plurality of evenly distributed first springs 44 are provided on the inner side of the inclined plane blocks 43. Push blocks 45 are provided on the inner side of the control cavity 35 and on both sides of the limit plate 4. The push blocks 45 are provided with inclined planes in contact with the inclined plane blocks 43, and an electric push rod 451 for pushing the push blocks 45 to slide is installed inside the control cavity 35.

[0059] When the electric push rod 451 operates to push the push block 45 close to the inclined block 43, the inclined surface on the push block 45 can squeeze the inclined block 43, so that the limit plate 4 slides outward along the control cavity 35, the fixed block 41 extends to the outside of the strip groove 36, and the anti-slip pad 42 extends to the outside of the square groove 37, thereby further fixing the guardrail plate and improving the stability of the guardrail plate.

[0060] When the electric push rod 451 drives the push block 45 away from the inclined block 43, under the elastic action of the first spring 44, the limit plate 4 can slide toward the inside of the control cavity 35, and the fixed block 41 and the anti-slip pad 42 can be stored inside the control cavity 35, so that the suction cup 62 can drive the guardrail plate to move outward, thereby facilitating the replacement and installation of the guardrail plates inside the first clamp plate 32 and the second clamp plate 33.

[0061] like Figure 9-12As shown, the movable arm 5 is rotatably connected to the bottom end of the first clamping plate 32, a control rod 51 is welded and fixed on the movable arm 5 and close to the first clamping plate 32, a fifth hydraulic cylinder 511 is installed on the outer wall of the first clamping plate 32, the cylinder body of the fifth hydraulic cylinder 511 is rotatably connected to the first clamping plate 32, and the piston rod of the fifth hydraulic cylinder 511 is rotatably connected to the control rod 51. When the fifth hydraulic cylinder 511 is running, it can drive the movable arm 5 to rotate on the first clamping plate 32. When the guardrail board is clamped and transported, the movable arm 5 and the storage box 52 can be driven to the outside of the first clamping plate 32 to avoid interfering with the clamping work of the guardrail board. When the guardrail board is installed, the movable arm 5 and the storage box 52 can be driven to the right side of the clamping plate seat 31, so as to facilitate the suction cup mechanism to grab a single guardrail board for installation.

[0062] A first bidirectional screw 54 is installed inside the storage box 52, and a symmetrically distributed first slider 55 is arranged on the first bidirectional screw 54. The first slider 55 slides along the inner wall of the storage box 52 and is threadedly connected to the first bidirectional screw 54. A rotatably connected propulsion plate 56 is arranged between the first slider 55 and the movable plate 53. A first motor 541 for driving the first bidirectional screw 54 to rotate is installed on the outer side of the storage box 52. When the first motor 541 runs to drive the first bidirectional screw 54 to rotate, it can drive the two groups of first sliders 55 to move relative to each other, and push the movable plate 53 close to the clamping plate seat 31 through the propulsion plate 56, so that the suction cup 62 can grab the guardrail plate.

[0063] An array of sleeves 6 are installed on the side wall of the movable plate 53, one end of the movable column 61 is slidably connected to the inner wall of the sleeve 6, and a suction cup 62 is installed on the other end of the movable column 61 and located on the outside of the sleeve 6. A second spring 63 connected to the movable column 61 is installed inside the sleeve 6. When the suction cup 62 grabs the guardrail plate, the movable column 61 can be further squeezed by the second spring 63 to improve the contact effect between the suction cup 62 and the guardrail plate, thereby effectively preventing the guardrail plate from falling off.

[0064] Working principle: when installing and replacing the guardrail board, the lifting frame 3 is moved to the top of the vehicle body 1, and then the first hydraulic cylinder 17 is operated to drive the adjusting frame 14 to rotate through the extension arm 16, and the adjusting frame 14 drives the lifting seat 15 and the telescopic arm 2 to lift, thereby driving the lifting frame 3 close to the guardrail board to be lifted, and then the clamping plate seat 31 is in contact with the uppermost guardrail board, and the fourth hydraulic cylinder 34 is operated to drive the first clamping plate 32 and the second clamping plate 33 to rotate, so that the clamping plate seat 31, the first clamping plate 32 and the second clamping plate 33 cooperate with each other to clamp multiple guardrail boards at the same time, and then the electric push rod 451 is operated to push the push block 45 close to the inclined block 43, and the inclined block 43 pushes the limit plate 4 to slide, so that the fixed block 41 and the anti-slip pad 42 on the limit plate 4 further fix the guardrail board, thereby improving the stability of the guardrail board, and then the lifting frame 3 and the guardrail board are driven to the installation position through the lifting assembly;

[0065] Furthermore, the third hydraulic cylinder 313 is operated to drive the clamping seat 31 to rotate, and the clamping seat 31 is adjusted to a vertical state. Afterwards, the fifth hydraulic cylinder 511 is operated to drive the movable arm 5 to rotate, and the storage box 52 is rotated to the right side of the clamping seat 31. Next, the first motor 541 is operated to drive the first bidirectional screw 54 to rotate, and the first slider 55 and the push plate 56 cooperate with each other to push the movable plate 53 close to the guardrail plate, and make the suction cup 62 in close contact with the guardrail plate, so as to grab the guardrail plate. Afterwards, the electric push rod 451 drives the push block 45 away from the limit plate 4, and stores the fixed block 41 and the anti-slip pad 42 into the control chamber 35. Afterwards, the movable plate 53 is driven close to the storage box 52, so that the suction cup 62 drives the single guardrail plate to move outward, and drives the guardrail plate to the installation position, so that the guardrail plate can be quickly installed.

[0066] Embodiment 2:

[0067] This embodiment is an improvement based on the first embodiment:

[0068] like Fig.10 and Fig.13 As shown, in order to further improve the stability of the hoisting frame 3 and the clamping mechanism guardrail plate during installation, a storage frame 7 is provided on the outer side of the second clamping plate 33, and a supporting mechanism is provided on the inner side of the storage frame 7, and the supporting mechanism includes a symmetrically distributed supporting frame 71 and a second slider 73 and a bracket 74.

[0069] The storage frame 7 is welded and fixed to the outer wall of the second clamping plate 33, and two groups of support frames 71 are symmetrically arranged on the inner side of the storage frame 7. One end of the support frame 71 is rotatably connected to the end of the support frame 71, and the other end of the support frame 71 is installed with a movable wheel 711. A second bidirectional screw 72 is installed inside the storage frame 7, and a symmetrically distributed second slider 73 is arranged on the second bidirectional screw 72. The second slider 73 is slidably connected to the inner wall of the storage frame 7 and is threadedly connected to the second bidirectional screw 72. A rotatably connected bracket 74 is arranged between the second slider 73 and the support frame 71, and a second motor 721 that drives the second bidirectional screw 72 to rotate is installed on the outer wall of the storage frame 7.

[0070] When the clamp seat 31 is in a horizontal state, the supporting mechanism is stored inside the storage frame 7, reducing the space occupied by the supporting mechanism, so that the first clamp plate 32 and the second clamp plate 33 can clamp the guardrail plate. When the clamp seat 31 is in a vertical state, the second clamp plate 33 is located directly below the guardrail plate, so that the second motor 721 runs to drive the second bidirectional screw 72 to rotate, so that the second slider 73 moves relatively on the second bidirectional screw 72, and pushes the support frame 71 to gradually unfold through the bracket 74, so that the movable wheel 711 at the bottom of the support frame 71 contacts the ground, and can be supported under the second clamp plate 33, thereby improving the stability of the clamping mechanism and the guardrail plate during the installation process. At the same time, when multiple guardrail plates are continuously installed, the movable wheel 711 is used to facilitate the clamping mechanism to drive the guardrail plate to move along the installation route.

[0071] In addition, the present application also provides a method for using a highway guardrail quick replacement device, comprising the following steps:

[0072] S1: The original guardrail is removed, so that the clamping plate seat 31 is in a vertical state, and the clamping plate seat 31 is close to the original guardrail, so that the first clamping plate 32 and the second clamping plate 33 are located on the upper and lower sides of the original guardrail, and the first clamping plate 32 is slightly opened upward, and the connecting bolts of the highway guardrail are manually removed, and the original guardrail is pushed into the inner side of the clamping mechanism, so that the vehicle body 1 continues to move along the original guardrail, and multiple guardrails are pushed to the inner side of the clamping mechanism in turn, and the guardrail is further fixed by the fixing mechanism, and then the hoisting assembly drives the hoisting frame 3 to hoist the original guardrail onto the vehicle body 1 for storage;

[0073] S2: Lift the new guardrail board so that the clamping plate seat 31 is in a horizontal state, the suction cup mechanism is stored on the outside of the first clamping plate 32, the support mechanism is stored in the storage frame 7, the clamping plate seat 31 is close to the new guardrail board, and the first clamping plate 32 and the second clamping plate 33 are driven to rotate by the fourth hydraulic cylinder 34, so that the clamping mechanism clamps and fixes multiple new guardrail boards at the same time, and at the same time, the fixing mechanism further fixes the guardrail board, and then the lifting frame 3 and the clamping mechanism are driven to move by the lifting assembly to drive the new guardrail board to the installation position;

[0074] S3: Installation of new guardrail board. The clamping plate seat 31 is adjusted to a vertical state by the third hydraulic cylinder 313, so that the opening of the clamping mechanism faces the installation position. At the same time, the second motor 721 is operated to make the support frame 71 gradually expand downward, so that the support mechanism supports under the second clamping plate 33. Then, the movable arm 5 drives the suction cup mechanism to the right side of the clamping plate seat 31, and the first motor 541 is operated to drive the movable plate 53 to move, so that the suction cup mechanism grabs the outermost guardrail board. After that, the limiting effect of the fixing mechanism on the guardrail board is cancelled, and the suction cup mechanism drives the guardrail board to move to the right to the outer side of the first clamping plate 32. After the guardrail board is manually installed and fixed, the vehicle body 1 is moved along the installation route, and the clamping mechanism drives the guardrail board to the next installation position, and the guardrail boards on the inner side of the clamping mechanism are installed and fixed in turn.

[0075] 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.
