Description

Technical Field

[0001] The invention relates to the technical field of guardrail repair vehicles, in particular to a guardrail repair vehicle with high-stability support. Background Art

[0002] The guardrail repair vehicle is a device specially designed for the maintenance and repair of road guardrails. Its main functions are to pull out piles and drive piles. It can quickly repair damaged or repaired road guardrails and restore road safety. In addition, it can also carry various guardrail materials and tools for the installation or replacement of guardrails, as well as regular maintenance of guardrails, such as cleaning, painting, and replacement of damaged parts.

[0003] In actual operation, the repair vehicle mainly drives and installs the guardrail piles. In this process, the operation and processing are relatively limited, and only a single processing effect can be achieved. The repair and maintenance of damaged guardrails need to be collected and transported to the corresponding location for centralized processing. In this way, the transportation process takes time, including loading and unloading, transportation and rearrangement, which may extend the overall repair time, affect the timely restoration of roads or related facilities, and make it impossible to solve on-site problems in time, resulting in aggravation of traffic congestion, safety hazards and other problems. In addition, after being transported to other places, the repair environment may need to be rearranged and adapted, which may increase the difficulty and complexity of the operation and affect the repair effect;

[0004] Moreover, after most damaged guardrail columns are abandoned and pulled out by the repair vehicle, there will be a lot of stones and dirt on their outer walls. The dirty outer walls of the guardrail columns may increase the difficulty and complexity of construction. For example, if the dirt on the guardrail contains sticky substances or particles, these substances may adhere to the piling equipment, causing the performance of the equipment to decline, requiring additional cleaning time, thereby reducing the piling efficiency, and affecting the accuracy and stability of piling. The dirt will change the friction coefficient of the guardrail surface, resulting in inaccurate positioning of the pile body or difficulty in fixing it during piling.

[0005] Therefore, a guardrail repair vehicle with high stability support is proposed. Summary of the invention

[0016] Preferably, a control module is installed on the outer wall of the vehicle body beside the liquid tank, and the control module is electrically connected to the hydraulic hammer head, the motor, the electric telescopic rod, the water pump and the float sensor.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. First, during the activation of the piling component, the user can synchronously trigger the straightening operation of the damaged bent guardrail. In the corresponding implementation process of the two types of switching operations, the unevenly damaged parts of the guardrail edge and the temporary binding between the separated guardrails of different specifications can be uniformly cut off according to the damage of the guardrail. Both directly use the piling power to directly realize the emergency repair of the guardrail. On the one hand, it can realize the multiple utilization of mechanical energy in the process of pile hammering. On the other hand, there is no need for manual repeated processing. The contact between the porous plate and the surface of the guardrail is more uniform, which helps to apply pressure at multiple points at the same time, so as to more accurately control the straightening direction and degree of the guardrail, improve the straightening accuracy, and provide the processing behaviors required for emergency repair in many aspects, so as to restore the function of the guardrail faster and reduce interference and delays to traffic.

[0019] Secondly, compared with the straightening, cutting and guardrail fixing actions in the prior art, it is necessary to place the deformed guardrail plate on the ground, and use pliers, heavy objects or hammers and other tools to apply appropriate pressure or knock on the damaged part to achieve the effect of straightening the deformed guardrail. The whole is driven by a hydraulic hammer head. In the process of switching from straightening to cutting, the deployment positions on both sides are directly replaced by the rotation of the transmission gear, so that the switching process is smoother. When the cutting knives on both sides are adjusted to cut downward, the guide receiving block can limit the moving direction of the cutting knife and the guardrail fixing operation on the other side, so that the power transmission during the contact and cutting between the cutting knife and the guardrail and the connection and fixing operation can be more stable, thereby ensuring the accuracy of the cutting effect on the damaged edge of the guardrail.

[0020] During the piling process, the spraying component continuously provides wetting to the slope soil, and when the piling component switches its behavior to the damaged guardrail repair, the spraying direction of the spraying component is synchronously driven to switch following the adjustment of the cutting knife and the temporary reinforcement connection mechanism, so that it first provides sufficient flushing to the temporarily fixed separated guardrail. The centers of the two end ranges of the arc track are set directly above the piling operation area and the guardrail repair area. In the default state, the medium spraying position is in the piling operation area. After the damaged guardrail repair process is switched, the medium spraying position is adjusted to the repair area, and when the cutting knife and the temporary reinforcement connection mechanism are switched again, the supply medium is directly switched, and the paint is inserted to repair the paint peeling of the two groups of guardrails that have been fixed and repaired. Through the two-step switching operation, the purpose, type and object of the spraying medium are conveniently switched, so that it can complete the switching synchronously with the guardrail repair process, and synchronously complete the sludge flushing and paint repair of the repaired guardrail.

[0021] Secondly, compared with the traditional spraying treatment, a four-way pipe and the bottom of the circular pipe are set, and the circular pipe and the four-way pipe are set to be rotatably connected. After the liquid medium is output from the liquid tank, the medium can be driven by the water pump power source to rotate in a scattered manner during spraying to adjust the spraying range of the medium. The hinged setting of the vertical plate and the horizontal plate can change the spraying angle of the medium under the drive and adjustment of the electric telescopic rod. Compared with the fixed spraying or constantly adjusting the position of the guardrail in the prior art, the medium can be sprayed evenly and the coverage area is wider. Through the setting of a ninety-degree arc track, the path can be guided and positioned when switching between the two spraying positions, and it can be adjusted according to the set path to provide a smooth turning transition. Spraying along the arc trajectory can make the target area fully covered by the liquid, ensure the accuracy and consistency of the spraying position, reduce the time waste caused by direction change, and thus improve the operational efficiency of the switching behavior.

[0022] First, when the cutting knife is switched to the temporary reinforcement connection mechanism, during this switching period, the temporary reinforcement connection mechanism will be synchronously applied to the two guardrails to be repaired after cutting, so that after the two guardrails are close to the temporary reinforcement connection mechanism, the U-shaped iron wire is applied for bidirectional wrapping, and after the temporary reinforcement connection mechanism moves to the limit distance, the torsion binding of the iron wire is directly completed. The wrapping and torsion binding of the two groups of fences to be repaired by the U-shaped iron wire does not require manual participation throughout the process, which accelerates the completion of the guardrail repair while ensuring the tightness of the guardrails connected to each other after damage;

[0023] Secondly, compared with the prior art method of repairing the guardrail by manual welding, rope connection or cement pouring reinforcement, the special-shaped plywood on both sides can be opened during the downward movement by guiding and engaging the fixed tooth plate frame while switching to the temporary reinforcement connection mechanism to move downward. Subsequently, the U-shaped wire in the wire groove is directly inserted into the connecting hole to simultaneously complete the connection of the two sets of damaged guardrails. The wire connection can disperse the force on the guardrail and reduce the pressure on the force point, thereby avoiding the risk of the guardrail being damaged again due to excessive pressure due to subsequent collision. It has strong adaptability and flexibility, making the repair work more convenient and efficient.

[0024] 4. When the vehicle body is undergoing guardrail repair operations, the arrival of the piling components directly drives the arrival of the emergency repair replacement mechanism and the temporary reinforcement connection mechanism, so that at the emergency repair site, as the medium switching maintenance mechanism is in place, the guardrail piling, straightening, cutting, secondary fixation, flushing and paint repair operations can be completed simultaneously. The direct arrangement of components required for various operations can then be directly constructed at the emergency repair site, providing all kinds of basic behaviors required for emergency repairs in all directions, and multiple maintenance processes or construction operations can be carried out simultaneously. Compared with the existing technology that requires the guardrails to be collected and transported to the processing plant for reprocessing, the production line content is compacted, reducing additional transportation and storage costs as well as construction delays or work stoppage losses caused by the lack of guardrails.

[0043] The emergency repair and replacement mechanism 7 is used to repair the damaged and deformed guardrail while the vehicle body 1 is installing a new guardrail pile body.

[0044] The emergency repair replacement mechanism 7 also includes two stands 79 fixedly connected to the top of the porous plate 74, the middle parts of the stands 79 on both sides are rotatably connected to the transmission gears 710, and the middle parts of the porous plate 74 are slidably connected to a pair of racks 714, wherein the bottom ends of the racks 714 on both sides are fixedly connected to the cutting knives 78, and the cutting knives 78 on both sides are slidably connected to the inside of the second cavities 76 on both sides, and the transmission gears 710 on both sides are meshed and connected with the racks 714 on both sides, and the middle parts of the transmission gears 710 on both sides are fixedly connected to the pulleys 71 1. The pulleys 711 on both sides are rotatably connected to the middle of the outer wall of the two side seats 79 respectively, and the pulleys 711 on both sides are connected by a connecting belt 712. A motor 713 is fixedly connected to the outer wall of any side seat 79, and the driving end of the motor 713 is fixedly connected to the middle of any side pulley 711. Both sides of the two side seats 79 are fixedly connected to the guide receiving block 715, and the inner wall of the rack 714 is slidably connected to the outer wall of the guide receiving block 715. A knocking plate 716 is fixedly connected to the middle of one side of the hydraulic hammer head 5 close to the porous plate 74;

[0045] A temporary reinforcement connection mechanism 8 is used to temporarily reinforce and splice multiple guardrails after emergency repairs to facilitate the restoration of road use;

[0046] The medium switching maintenance mechanism 9 is used to clean the outer wall of the guardrail after the emergency repair and to spray paint and maintain it to ensure the subsequent normal use. The medium switching maintenance mechanism 9 includes an arc-shaped rail 91 fixedly connected to the side of the hydraulic hammer head 5 close to the porous plate 74, and the middle part of the side of the hydraulic hammer head 5 away from the storage frame 2 is rotatably connected to a vertical plate 92, and the middle part of the outer wall of the vertical plate 92 is rotatably connected to a horizontal plate 93, and the middle part of the side of the vertical plate 92 away from the vehicle body 1 is rotatably connected to an electric telescopic rod 94, and the telescopic end of the electric telescopic rod 94 is fixedly connected to the horizontal plate 93, and the bottom of the horizontal plate 93 is fixedly connected to a spring ball column 95, and the outer wall of the spring ball column 95 is slidably connected to the inner wall of the arc-shaped rail 91;

[0047] The medium switching maintenance mechanism 9 also includes a circular tube 96, which is fixedly connected to one end of the horizontal plate 93 away from the vertical plate 92, and a four-way tube 97 is fixedly connected to the bottom of the circular tube 96, and a plurality of nozzles are fixedly connected to the bottom of the four-way tube 97;

[0048] The medium switching maintenance mechanism 9 also includes two liquid tanks 98. The liquid tanks 98 on both sides are fixedly connected to the outer wall of the vehicle body 1. A three-way hose 99 is fixedly connected to the middle of the circular tube 96. The two ends of the three-way hose 99 away from the circular tube 96 are respectively passed through and fixedly connected to the inside of the liquid tanks 98 on both sides. The middle of the outer wall of the two ends of the three-way hose 99 away from the circular tube 96 are fixedly connected to a water pump 910. The middle of the liquid tanks 98 on both sides is provided with a float sensor 911.

[0049] The bottom of the receiving bottom plate 71 is slidably attached to the inner wall of the vehicle body 1, the wave plates 77 on both sides are symmetrically arranged with respect to the horizontal center line of the receiving bottom plate 71, and the elastic stiffness of the connecting spring 73 is matched with the weight of the porous plate 74;

[0050] Better: As the telescopic plate 3 is pushed out of the storage frame 2 under the adjustment of the hydraulic drive system of the vehicle body 1 itself, it can drive the receiving bottom plate 71 fixedly connected to its bottom and its corresponding structure on the top to slide out synchronously from the inside of the vehicle body 1 to the outside of the vehicle body 1 for use. The setting of the wave plate 77 can position and place two deformed or damaged guardrails, and the bottoms of the guardrails on both sides are correspondingly placed in the middle position of the top of the receiving bottom plate 71. As the guardrail installation and piling operation proceeds, the hydraulic hammer head 5 moves downward in the middle of the guide rail 4 to knock on the pile body erected on the ground. During this process, the knocking plate 716 can synchronously move with the hydraulic hammer head 5, knocking and squeezing the porous plate 74 downward, so that the porous plate 74 squeezes the connecting spring 73 downward to slide on the outer wall of the four-side uprights 72, and then the porous plate 74 can squeeze the bent and deformed guardrail downward to restore it to a flat state.

[0051] Wherein: the cutting knives 78 on both sides and the temporary reinforcement connection mechanism 8 are both located inside the second cavity 76 and the first cavity 75 in the default state, and the motor 713 is electrically connected to the control module 6 in real time;

[0052] Better: For abandoned guardrails of different degrees of damage, after they are manually placed on the top of the wave plate 77, the emergency repair mode can be selected according to the requirements of the repair. For example, for cracked and damaged guardrails, the damaged part can be placed in the position below the cutting knife 78 in the wave plate 77. The motor 713 is controlled by the control module 6 to operate. With the cooperation of the pulleys 711 on both sides and the connecting belt 712, the transmission gears 710 in the middle of the two side seats 79 can be driven to start rotating. With the rotation of the transmission gears 710 on both sides, the meshing racks 714 on both sides can be moved up and down accordingly, guiding the receiving block 715 can support and limit the rack 714 to ensure stability during the movement, thereby driving the cutting knife 78 and the temporary reinforcement connection mechanism 8 fixedly connected to each other at the bottom to switch up and down. When the cutting knife 78 moves downward with one side of the rack 714 and leaves the second cavity 76, it can move downward to contact the damaged part of the abandoned guardrail and cut off the end. As the adjustment operation proceeds, the cutting knife 78 moves in the opposite direction and retreats to the inside of the second cavity 76. At the same time, the temporary reinforcement connection mechanism 8 moves downward with the other side of the rack 714 to further trim the abandoned guardrail.

[0053] Wherein: the arc track 91 is set to a 90-degree track, the spring ball column 95 is provided with a spring inside, which can be flexibly compressed and reset, the liquid tanks 98 on both sides store water and paint respectively, and the setting of the float sensors 911 on both sides corresponds to the different volume heights of the water source and the paint liquid, and the obvious buoyancy difference generated by the bottom float ball can distinguish the different liquids on both sides;

[0054] Better: Corresponding to different working modes, when the guardrail pile is being driven in and installed, the construction personnel can move the horizontal plate 93 to adjust it to a perpendicular state with the guide rail 4 through the arc rail 91 and the spring ball column 95, so that the liquid outlet direction of the four-way pipe 97 is directly below the piling operation area. As the hydraulic hammer head 5 moves downward to strike the pile body, the soil in the piling operation area is sprayed with water in real time to moisten the dry and hard soil, making the subsequent piling operation smoother and more convenient. When the corresponding option is to simultaneously carry out the emergency repair and finishing of the abandoned guardrail, the position of the horizontal plate 93 can be adjusted by rotating in the opposite direction so that the four-way pipe 97 is directly below the piling operation area. The spraying direction of the tube 97 is directly above the porous plate 74. After the multiple abandoned guardrails on the receiving bottom plate 71 are trimmed and spliced, the water pump 910 on the outer wall of the port of the three-way hose 99 connected to the water source liquid tank 98 can be controlled to open accordingly, so that the water source sprays down and then flows downstream through several through holes in the porous plate 74 to rinse and clean the outer wall of the abandoned guardrail. Then, the control module 6 controls the water pump 910 on the outer wall of the port on one side of the three-way hose 99 corresponding to the paint liquid tank 98 to control the output of the paint liquid, and spray paint and maintain the corrected guardrail. After drying, it can be put into use on the road site again.

[0055] The temporary reinforcement connection mechanism 8 includes two top frame plates 81 fixedly connected to the bottom of the racks 714 on the other two sides. The top frame plates 81 on both sides are respectively slidably connected to the inside of the first cavities 75 on both sides. The middle parts of the top frame plates 81 on both sides are rotatably connected to the rotating shafts 82. The outer walls of the rotating shafts 82 on both sides are fixedly connected to the connecting gears 83 at both ends. The middle parts of the opposite sides of the connecting gears 83 on both sides are fixedly connected to the special-shaped clamping plates 84. The special-shaped clamping plates 84 on both sides are staggered. The middle parts of the inner walls of the special-shaped clamping plates 84 on both sides are provided with iron The wire groove 87, the temporary reinforcement connection mechanism 8 also includes a fixed tooth plate frame 86 fixedly connected to the inner wall of the first cavity 75, the two sides of the fixed tooth plate frame 86 are staggered and the inner wall is respectively meshed with the connecting gears 83 on both sides, and the middle of the inner wall of the wire groove 87 on both sides is fixedly connected with a penetrating ring 85. The outer wall of the vehicle body 1 is located next to the liquid tank 98 and a control module 6 is installed. The control module 6 is electrically connected to the hydraulic hammer 5, the motor 713, the electric telescopic rod 94, the water pump 910 and the float sensor 911;

[0056] Wherein: the outer walls of the two side special-shaped clamping plates 84 close to each other are attached to each other, and the bottom ends are provided with parallel staggered special-shaped hook claws;

[0057] The U-shaped wire is preferably inserted into the wire grooves 87 in the middle of the special-shaped clamping plates 84 on both sides by the two ends of the U-shaped wire respectively, and the fixed toothed plate frame 86 is fixedly connected to the inside of the first cavity 75. The top frame plate 81 moves downward with the switching process of the cutting knife 78, and the connecting gears 83 on both sides can be respectively rotated in opposite phases on the outer wall of the rotating shaft 82, so that the connecting gears 83 on both sides roll downward along the inner wall of the fixed toothed plate frame 86, thereby realizing the clockwise rotation of the special-shaped clamping plate 84 on one side and the counterclockwise rotation of the special-shaped clamping plate 84 on the other side. By relative rotation, the U-shaped iron wire can be inserted into the connecting holes of the guardrails on both sides, and with the cooperation of the staggered special-shaped hooks at the end positions, the staggered tightening process of the U-shaped iron wire ends can be completed, thereby completing the temporary reinforcement connection processing of the two damaged guardrails. Correspondingly, when the temporary reinforcement connection mechanism 8 and the cutting knife 78 are switched in reverse and moved upward to be stored in the first cavity 75, the special-shaped clamping plates 84 on both sides can be rotated in reverse under the guidance of the fixed tooth plate frame 86, and withdrawn from the connecting holes of the guardrails, and then the switching and storage of the temporary reinforcement connection mechanism 8 is completed in the process of moving upward.

[0058] The above implementation works as follows:

[0059] The initialization steps are as follows:

[0060] The emergency repair replacement mechanism 7, the temporary reinforcement connection mechanism 8 and the medium switching maintenance mechanism 9 are all consistent with the guide rail 4, i.e., the hydraulic hammer head 5, and are stored inside the vehicle body 1 in the default state. When the work is about to start, the telescopic plate 3 is pushed out from the storage frame 2 as adjusted by the hydraulic drive system of the vehicle body 1 itself, and at the same time drives the receiving bottom plate 71 fixedly connected to the bottom thereof and the corresponding structure on the top thereof to slide out synchronously from the inside of the vehicle body 1 to the outside of the vehicle body 1 for use, and the cutting knives 78 on both sides and the medium switching maintenance mechanism 9 are respectively stored in the second cavity 76 and the first cavity 75 in the unused state, and a U-shaped iron wire of corresponding size is put into the iron wire groove 87 on the inner wall of the special-shaped clamping plate 84 in the temporary reinforcement connection mechanism 8 for standby use;

[0061] The working steps are as follows:

[0062] like Figure 1 - Figure 4 and Figure 6 - Figure 8As shown, for abandoned guardrails with different degrees of damage, the emergency repair mode is selected according to the requirements for repair. For abandoned guardrails with only bending and deformation damage, the construction personnel place them on the top of the corrugated plate 77. The corrugated plate 77 can position and place the two deformed or damaged guardrails. The bottoms of the guardrails on both sides are placed in the middle position of the top of the receiving bottom plate 71. As the guardrail installation and piling operation proceeds, the hydraulic hammer head 5 moves downward in the middle of the guide rail 4 to knock on the pile body erected on the ground. During this process, the knocking plate 716 can synchronously move with the hydraulic hammer head 5 to knock and squeeze the porous plate 74 downward, so that the porous plate 74 squeezes the connecting spring 73 downward to slide on the outer walls of the four side uprights 72, and then the bent and deformed part of the guardrail can be squeezed downward through the porous plate 74 to restore it to a flat state. For abandoned guardrails that are broken and have defective ports, the construction personnel can place the damaged part in the corrugated plate 77 facing the cutting knife 78 At the lower position, the motor 713 is controlled by the control module 6 to operate, and the transmission gear 710 in the middle of the two side seats 79 can be driven to start rotating under the cooperation of the pulleys 711 and the connecting belt 712 on both sides. With the rotation of the transmission gears 710 on both sides, the racks 714 meshing and connected on both sides can be moved up and down accordingly, and the guide receiving block 715 can support and limit the racks 714 to ensure the stability during the movement, thereby driving the cutting knife 78 and the temporary reinforcement connection mechanism 8 fixedly connected to each other at the bottom to switch up and down. When the cutting knife 78 moves downward with the rack 714 on one side and leaves the second cavity 76, it can move downward to contact the damaged part of the abandoned guardrail and cut off the end. With the progress of the adjustment operation, the cutting knife 78 moves in the opposite direction and retreats to the inside of the second cavity 76. At the same time, the temporary reinforcement connection mechanism 8 moves downward with the rack 714 on the other side to further trim the abandoned guardrail.

[0063] like Figure 6 - Fig.11As shown, the guardrail after trimming and cutting can be temporarily reinforced and connected, and the connecting holes of the two guardrails are manually adjusted to be directly below the temporary reinforcement connection mechanism 8. When the temporary reinforcement connection mechanism 8 moves downward with the rack 714 on the other side, the connecting gears 83 on both sides can roll downward along the fixed toothed plate frames 86 engaged and connected on both sides, so that the connecting gears 83 on both sides rotate in opposite directions on the outer wall of the rotating shaft 82 respectively, so that the special-shaped splint 84 on one side rotates clockwise and the special-shaped splint 84 on the other side rotates counterclockwise, and the relative rotation of the special-shaped splints 84 on both sides completes the closing. By adjusting the closing, the U-shaped wire can be inserted into the connection holes of the guardrails on both sides, and the staggered special-shaped hook claws at the end positions can be set to complete the staggered tightening of the ends of the U-shaped wire, so as to complete the temporary reinforcement connection of the two damaged guardrails. Correspondingly, when the temporary reinforcement connection mechanism 8 and the cutting knife 78 are switched in reverse and moved upward to be stored in the first cavity 75, the special-shaped clamping plates 84 on both sides can be reversely rotated under the guidance of the fixed tooth plate frame 86, and withdrawn from the connection holes of the guardrails, and then the switching and storage of the temporary reinforcement connection mechanism 8 is completed in the process of moving upward;

[0064] like Figure 2 and Figure 4 - Figure 8As shown, when the guardrail pile body is being driven into and installed, the construction personnel can move the cross plate 93 to adjust it to a perpendicular state with the guide rail 4 through the arc rail 91 and the spring ball column 95, so that the liquid outlet direction of the four-way pipe 97 is directly below the pile driving operation area. As the hydraulic hammer head 5 moves downward to strike the pile body, the soil in the pile driving operation area is sprayed with water in real time to moisten the dry and hard soil, making the subsequent pile driving operation smoother and more convenient. When the corresponding option is to simultaneously carry out emergency repair and finishing of the abandoned guardrail, the position of the cross plate 93 can be adjusted by rotating in the reverse direction so that the spraying direction of the four-way pipe 97 is directly above the porous plate 74. The liquid tanks 98 on both sides store water and paint respectively. The setting of the float sensors 911 on both sides distinguishes the different liquids on both sides by the obvious buoyancy difference generated by the bottom float corresponding to the different capacity heights of the water source and the paint liquid, so as to facilitate the subsequent control. The control module 6 controls the water pumps 910 on both sides to distinguish between water and paint and then output them. The water pumps 910 can provide output power for the output spraying of the two media. After the multiple abandoned guardrails on the receiving bottom plate 71 are trimmed and spliced, the water pump 910 on the outer wall of the three-way hose 99 port connected to the water source liquid tank 98 can be controlled to open accordingly, so that the water source sprays down and then flows downstream through several through holes in the porous plate 74 to rinse and clean the outer wall of the abandoned guardrail. Then, the control module 6 controls the water pump 910 on the outer wall of the port on one side of the three-way hose 99 corresponding to the paint liquid tank 98 to control the output of the paint liquid, and spray paint and maintain the corrected guardrail. After drying, it can be put into use on the road site again, realizing real-time emergency repair on site, without the need to collect and transport the abandoned guardrails, speeding up the overall emergency repair time, so that the road-related facilities can be restored to use as soon as possible.
