Description

Technical Field

[0001] The present invention specifically relates to an anti-collision device for highway reconstruction and expansion projects and an installation method thereof, belonging to the technical field of highway anti-collision devices. Background Art

[0002] In the early days, there were few lanes on highways. To meet the needs of traffic volume growth in these areas, the existing highways were widened and reconstructed. When a highway is expanded, in order to protect the driving vehicles and construction workers, guardrails must be used to isolate the construction area; currently, in order to reduce the possibility of danger caused by vehicles straying into the construction area, temporary guardrails are usually placed to enclose the construction area; however, the anti-collision ability of temporary guardrails is relatively low. When a vehicle on the highway deviates from the lane or gets out of control and rushes towards the temporary guardrail, due to the high speed of the vehicle and the poor anti-collision ability of the temporary guardrail, it increases the accidental risk for the staff in the highway construction area; for this reason, Chinese Patent Publication No.: CN114718380A discloses an anti-collision device for highway reconstruction and expansion projects and an installation method thereof. This structure can improve the stability of the main body of the protection board during use. A rotating seat and an arc-shaped frame are arranged at one end of the movable rod, which can fix the front wheels of the vehicle when the main body of the protection board is impacted when the vehicle gets out of control; another example is the authorized publication number: CN113775241B, which discloses an anti-collision device for highway reconstruction and expansion projects. This structure can improve the protection effect of the guardrail on the construction area; however, the above structures generally have a general ability to decompose the anti-collision force, and they are all position-fixed anti-collision structures. Since the construction area is constantly changing, the above structures cannot protect the construction workers in a follow-up manner. Summary of the Invention

[0003] To solve the above problems, the present invention proposes an anti-collision device for highway reconstruction and expansion projects and an installation method thereof, which can move following the construction position, continuously maintain the anti-collision ability during the movement, and use a frame structure to protect the construction area, with strong anti-collision ability.

[0004] The anti-collision device for highway reconstruction and expansion projects of the present invention includes:

[0005] A tire part limiting unit, the tire part limiting unit includes a beam plate, and a plurality of unloading arrays are arranged at intervals on the front side of the beam plate;

[0006] A vehicle body limiting unit, the vehicle body limiting unit includes a plurality of guardrail plates, and rubber rollers are rotatably arranged between the guardrail plates through guide columns; a row of support beams are fixedly arranged at intervals on the back of the guardrail plates; the bottom parts of the support beams are respectively fixed to the beam plate and the rear side of the unloading array;

[0007] When a vehicle hits the anti-collision device at a certain angle, the front of the vehicle contacts the rubber roller, the front of the vehicle rubs against the rubber roller, the rubber roller rotates, and the vehicle's driving path is corrected, so that the angle of attack between the vehicle and the guardrail is reduced, even if the vehicle tends to move in the direction parallel to the length of the guardrail; the front impact force of the anti-collision device is reduced, and at the same time, when the front of the vehicle contacts the rubber roller, the wheels synchronously contact the force unloading array, and the wheels decompose the impact force through the force unloading array. At the same time, through the elastic deformation of the rubber roller, the overall impact force of the vehicle can be decomposed and unloaded; the anti-collision device realizes anti-collision deformation at the front end through the above structure, which can reduce the impact force at the rear end of the entire anti-collision device;

[0008] The positioning walking unit comprises a channel steel, sealing plates are fixed at both ends of the channel steel, multiple groups of positioning units are arranged inside the channel steel, and an electromagnetic suction cup is fixed in the middle of the positioning unit; an automatic power moving vehicle is fixed at the bottom of the positioning unit, and hydraulic diagonal braces are fixed on both sides of the automatic power moving vehicle;

[0009] When the positioning walking unit is moving, the electromagnetic suction cup of the positioning unit at the odd position is pre-magnetically clamped with the channel steel, and the electromagnetic suction cup of the positioning unit at the even position is powered off. At the same time, the hydraulic diagonal brace of the positioning unit at the even position is gripped with the ground, and the power moving vehicle of the positioning unit at the odd position moves, driving the channel steel to move synchronously. When the channel steel moves to the set distance, the hydraulic diagonal brace at the odd position is gripped with the ground; the electromagnetic suction cup at the odd position is powered off, and the electromagnetic suction cup at the even position is powered on. Then, the hydraulic diagonal brace at the even position is retracted, so that the automatic power moving vehicle drives the positioning unit at the even position to drive the channel steel to move in a straight line. After walking to the right position, the hydraulic diagonal brace at the even position is controlled to extend, so that the hydraulic diagonal brace is gripped with the ground again;

[0010] Guide seats, the guide seats are provided in four groups, two groups of the guide seats are fixed at both ends of the beam plate; the other two groups of the guide seats are fixed at both ends of the channel steel;

[0011] The connecting bridge comprises a front connecting bridge and a rear connecting bridge. The front connecting bridge is a frame structure with a hollow bottom. The front connecting bridge is engaged with two guide seats at the front side and is fastened by bolts. The rear connecting bridge comprises a ramp plate. One end of the ramp plate is integrally formed with a straight rail beam, and the other end is integrally formed with a straight beam. The straight rail beam and the straight beam are slidably engaged with the two guide seats at the rear end. A power system is fixed inside the front connecting bridge.

[0012] After the connecting bridge and the guide seat are fitted and locked by bolts, the tire limit unit, the body limit unit, the adjustment walking unit and the connecting bridge can form a three-dimensional enclosure space. The front connecting bridge serves as a supporting component of the power system; the ramp of the rear connecting bridge can serve as a guide for engineering vehicles to enter and exit the construction area; at the same time, it serves as an anti-collision support system;

[0013] Fixed walking unit, the fixed walking unit is arranged at both ends of the vehicle body limit unit, the fixed walking unit includes an adjustment box fixed outside the guide seat, an elastic buffer unit is arranged inside the adjustment box, and an automatic power mobile vehicle is fixed at the bottom of the elastic buffer unit; when the adjustment walking unit walks, the fixed walking unit can walk synchronously, so as to drive the entire three-dimensional enclosure space to walk synchronously. The hydraulic strut of the fixed walking unit can be used as the position limit for anti-collision deformation at the front end.

[0014] Further, the force unloading array includes a force receiving platform fixed to the beam plate by bolts, a blow molding box is fixed to the front side of the force receiving platform, an impact platform is arranged on the front side of the blow molding box, hinge seats are fixed to the upper and lower parts on both sides of the force receiving platform, the blow molding box and the impact platform, and arc-shaped steel bars are hinged between adjacent hinge seats; the upper and lower arc-shaped steel bars face in opposite directions; an elastic body is filled inside the blow molding box; a right-angle opening is formed at the bottom of the support beam, and the right-angle opening is clamped to the top surfaces of the beam plate and the force receiving platform; when the vehicle tire impacts the force unloading array, it first contacts the impact platform, and the vehicle tire impacts the impact tire forward. At this time, due to the arc-shaped steel bar being limited between the impact platform and the force receiving platform, the arc-shaped steel bar undergoes elastic deformation, and the impact force is decomposed once until the impact platform contacts the blow molding box. When the blow molding box is impacted and deformed or damaged, the elastic body inside the blow molding box is extruded and deformed, and the impact force is decomposed twice, which can fully decompose the impact force, protect the vehicle and the personnel inside the vehicle, and can reduce the overall impact force of the protection space formed by the tire limit unit, the vehicle body limit unit, the adjustment walking unit and the connecting bridge.

[0015] Further, the elastic body is foam glue, a spring array or an airbag; the airbag is a filled spherical airbag or a mutually pressed laminated airbag; when the blow molding box is impacted and damaged or deformed, the vehicle body contacts the elastic body, so that the impact force can be further decomposed through the self-deformation of the foam glue, the spring array or the airbag.

[0016] Furthermore, the self-powered moving vehicle includes a moving vehicle body. A rolling groove is formed at the bottom of the moving vehicle body. A traveling wheel is rotatably installed inside the rolling groove through a bearing. The wheel axle of the traveling wheel extends out of the moving vehicle body movably and is fixed with a driven wheel. The driven wheel is connected to a driving wheel on a hydraulic motor through a transmission member. The hydraulic motor is fixed to the moving vehicle body. The two sides of the moving vehicle body are integrally formed with barrel seats obliquely. The hydraulic strut includes an oil cylinder fixed inside the barrel seat. A hinged ear seat is fixed to the piston end of the oil cylinder. A toothed disc is hinged to the hinged ear seat. When the self-powered moving vehicle is traveling, the hydraulic motor drives the driving wheel to rotate. The driving wheel drives the traveling wheel to rotate through the transmission member and the driven wheel. The traveling wheel travels along the ground. The driving wheel, the transmission member, and the driven wheel can adopt mutually meshing gears, a sprocket and chain structure, or a pulley and belt structure. When the traveling wheel travels to a set position, the oil cylinder acts to drive the hinged ear seat to brace obliquely forward until the toothed disc on the hinged ear seat presses against the ground and the gripping teeth on the toothed disc are pressed tightly against the ground, so that a stable triangular support state is formed among the moving vehicle body, the ground, and the hydraulic strut. When the channel steel moves, due to the ground gripping of the toothed disc of the hydraulic strut, the self-powered moving vehicle can be kept in this position unchanged until the hydraulic strut retracts, and then it can freely travel along the channel steel. When the channel steel is impacted, the hydraulic struts of each self-powered moving vehicle resist and decompose the impact force respectively. And due to the ground gripping of the toothed disc of the hydraulic strut, it is avoided that the anti-collision device impacts and shifts excessively.

[0017] Furthermore, a plurality of proximity switches are fixed on the channel steel. Whether the positioning unit travels in place can be monitored in real time through the proximity switches. After traveling in place, the positioning unit stops and the hydraulic strut is used for position locking and anti-collision support. The proximity switches can adopt mechanical proximity switches or infrared proximity switches. For example, when the positioning unit travels, first, the positioning unit located at an odd position drives the channel steel to travel. At this time, the positioning unit located at an even position remains stationary. When the channel steel travels, the proximity switch on the channel steel touches the positioning unit at the even position, and the positioning unit at the odd position stops traveling. The hydraulic strut is used for position locking and anti-collision support. Then, the positioning unit at the even position travels by itself until it actively touches the proximity switch, and then the positioning unit at the even position stops traveling. The hydraulic strut is used for position locking and anti-collision support.

[0018] Furthermore, the position adjusting unit includes an inner pedestal fixed to the top of the self-powered mobile vehicle by bolts, and the electromagnetic chuck is fitted and fixed on the inner pedestal; adaptive cavity seats are fixed on both sides of the inner pedestal along the traveling direction; multiple guide rods are slidably arranged opposite to each other on both sides of the adaptive cavity seat, and a limit nut is screwed on the inner side of the adaptive cavity seat for the guide rods; the other ends of the guide rods are fixed to the roller seats, and a first spring is sleeved between the opposite guide rods; a guide roller is rotatably installed on the roller seat, and the guide roller is movably pressed against both sides of the inner wall of the channel steel; top rods are fixed at the four ends of the top of the inner pedestal, a wheel seat is sleeved on the top rods, and a second spring is sleeved between the inner pedestal and the wheel seat for the top rods; a top wheel is rotatably installed on the wheel seat, and the top wheel abuts against the inner top of the channel steel; the self-powered mobile vehicle supports the inner pedestal, and the inner pedestal serves as the support system of the channel steel guiding component and the mounting seat of the electromagnetic chuck; when the self-powered mobile vehicle jolts during traveling, by compressing or releasing the second spring, the top wheel always fits against the top of the channel steel. When the top wheel moves up and down, the wheel seat is linearly guided by the top rod, so that the top wheel closely fits against the inner top of the channel steel. During the traveling of the self-powered mobile vehicle, due to the action of the first spring, the guide rods are pushed outwards, so that the roller seats are pushed outwards by the guide rods, and the guide rollers always contact both sides of the inner wall of the channel steel.

[0019] Furthermore, the elastic buffer unit includes a support body fixed to the top of the self-powered mobile vehicle. A guide rod is fixed to the top of the support body, and the guide rod movably passes through the position adjusting box and is screwed with a top nut; a third spring is arranged between the inner top of the position adjusting box and the support body for the guide rod; the elastic buffer unit can automatically adapt to ground fluctuations. When the self-powered mobile vehicle jolts during traveling, the support body jacks up and compresses the third spring, or releases the pressure of the third spring, so that the self-powered mobile vehicle always fits against the ground.

[0020] Furthermore, angle seats are fixed to the lower parts of both sides of the channel steel. The angle seats are fixed with wheel seats through damping rods, and a first follow-up traveling wheel is installed on the wheel seats; the angle seats, the damping rods and the first follow-up traveling wheels can support both sides of the channel steel, so that the channel steel is always supported on the ground. When the channel steel travels, the first follow-up traveling wheel can follow up, and the damping rod automatically adapts to the ground, so that the first follow-up traveling wheel always fits against the ground.

[0021] Further, a rear guide seat is slidably arranged on the straight rail beam, and the rear guide seat is fixed to the guide seat by bolts; a force-bearing support platform that slidably cooperates with the guide seat is integrally formed on the upper part of the straight rail beam; a front guide seat is fixed on one side of the front connecting bridge close to the vehicle body limiting unit, and second follower traveling wheels are rotatably installed at the bottoms of the front guide seat and the rear guide seat; since the slope plate is used for vehicles to enter and exit the construction area and reduce the speed of vehicles entering and exiting the construction area, therefore, the rear connecting bridge and the guide seat are adopted to swing freely up and down, so that the slope plate can be in full contact with the ground. When a vehicle enters and exits and presses on the slope plate, it will not cause the rear connecting bridge to deform. Specifically: fix the rear guide seat to the guide seat, the up and down sliding of the rear guide seat and the straight rail beam, and the straight beam of the rear connecting bridge and the guide seat can be assembled in a sleeve type, dovetail guide rail type or hook type, and the straight beam is assembled to the guide seat; when the vehicle body limiting unit is impacted, the impact force is transmitted to the position-adjusting traveling unit through the force-bearing support platform and the guide seat.

[0022] Further, an electric barrier is fixed on the top of the rear connecting bridge of the guide seat; both ends of the barrier rod of the electric barrier are arranged inside the guide seat; when there are no construction vehicles entering and exiting the construction area, the barrier rod of the electric barrier is inside the two guide seats. When the anti-collision device is impacted, the position between the vehicle body limiting unit and the position-adjusting traveling unit can be limited through both ends of the barrier rod; thus, a three-dimensional space anti-impact is formed by the barrier rod and the slope plate. When there are construction vehicles entering and exiting the construction area, the barrier rod of the electric barrier is lifted, and the vehicle can enter and exit the construction area smoothly.

[0023] Further, an electric rotary table is fixed in the middle of the bottom surface of the front connecting bridge, and an automatic power moving vehicle is installed at the bottom of the electric rotary table; the rotation direction of the electric rotary table can be controlled through the power system to adjust the traveling direction of the anti-collision device, so that the anti-collision device can smoothly travel in the curved area.

[0024] Further, the slope plate includes an inner beam body integrally formed at the bottoms of the straight rail beam and the straight beam, and a speed bump is arranged outside the inner beam body; a row of bottom wheels are fixed to the bottom surface of the inner beam body, and the bottom wheels protrude from the bottom of the speed bump; when a construction vehicle enters and exits the construction area, the vehicle decelerates through the speed bump, and the inner beam body and the speed bump of the slope plate can limit the position between the tire part limiting unit, the vehicle body limiting unit and the position-adjusting traveling unit. When the tire part limiting unit and the vehicle body limiting unit are impacted, the impact force can be transmitted to the position-adjusting traveling unit; the bottom wheels at the bottom of the speed bump contact the ground to provide support for the slope plate.

[0025] An installation method for an anti-collision device for highway reconstruction and expansion projects, which is used to install the anti-collision device for highway reconstruction and expansion projects. The method is as follows:

[0026] The first step is to arrange temporary guardrails. Long strip notches are opened on the traffic cones; multiple ropes are threaded through the long strip notches, and both ends of the ropes are respectively fixed to two anti-collision buffer vehicles; and the ropes are tensioned at the boundary line between the construction area and the driving area of the highway. Before the vehicle hits the anti-collision device, it first contacts the traffic cone, and the traffic cone is limited by multiple tensioned ropes to form a flexible tensioned net, realizing the unloading of the first impact force, and the remaining impact force is decomposed multiple times through the anti-collision device, which can protect the personnel inside the vehicle and at the same time protect the on-site construction personnel.

[0027] The second step is to assemble the anti-collision device. First, assemble the tire part limiting unit and the vehicle body limiting unit. Then, fix the fixed walking unit to both ends of the vehicle body limiting unit; then place the position-adjusting walking unit directly opposite on the opposite side of the vehicle body limiting unit, and snap the connecting bridge into the guide seat, and lock the connecting bridge with bolts.

[0028] The third step is to install the power system. Fix the power system to the front connecting bridge, and connect the power supply line, control line and fuel supply line of the anti-collision device to the power system; the power system protects the hydraulic station, power system and control system. The hydraulic station provides a set oil pressure, the power system provides a stable power supply, and the control system executes the control of the actions of each component.

[0029] Compared with the prior art, for the anti-collision device and its installation method for highway reconstruction and expansion projects of the present invention, the anti-collision device uses the tire part limiting unit and the vehicle body limiting unit to decompose the vehicle impact force and guide the vehicle, reducing the impact force of the vehicle on the anti-collision device, and supports the positions of the tire part limiting unit and the vehicle body limiting unit through the connecting bridge and the position-adjusting walking unit; it is movably arranged between the driving area and the construction area of the highway, can be used as an isolation fence, and adopts a frame structure to form a closed protection space in the construction area, with strong anti-collision ability. The anti-collision device can move following the construction position, and during the entire moving process, it can continuously maintain the anti-collision ability.

Detailed implementation manners

[0046] Embodiment 1:

[0047] As Figures 1 to 13 shown, the anti-collision device for highway reconstruction and expansion projects includes:

[0048] A tire part limiting unit, the tire part limiting unit includes a beam slab 1, and a plurality of force unloading arrays are arranged at intervals on the front side of the beam slab 1;

[0049] A vehicle body limiting unit, the vehicle body limiting unit includes a plurality of guardrail plates 2, and rubber rollers 3 are rotatably arranged between the guardrail plates 2 through guide columns; A row of beam supports 4 are fixedly arranged at intervals on the back of the guardrail plate 2; The bottoms of the beam supports 4 are respectively fixed to the beam slab 1 and the rear side of the force unloading array;

[0050] When a vehicle collides with the anti-collision device at a certain angle, the front of the vehicle touches the rubber roller 3, the front of the vehicle rubs against the rubber roller 3, the rubber roller 3 rotates, correcting the driving path of the vehicle, reducing the included angle between the vehicle and the guardrail plate 2, that is, making the vehicle tend to move parallel to the length direction of the guardrail plate 2; Reducing the frontal impact force of the anti-collision device, and at the same time when the front of the vehicle touches the rubber roller 3, the wheels synchronously touch the force unloading array, and the wheels decompose the impact force through the force unloading array. At the same time, through the elastic deformation of the rubber roller 3, the overall impact force of the vehicle can be decomposed and unloaded; The anti-collision device realizes front-end anti-collision deformation through the above structure, and can reduce the impact force at the rear end of the entire anti-collision device;

[0051] Position - adjusting walking unit, the position - adjusting walking unit includes channel steel 5, end plates are fixed at both ends of the channel steel 5, multiple groups of position - adjusting units 6 are arranged inside the channel steel 5, an electromagnetic chuck 7 is fixed in the middle of the position - adjusting unit 6; an automatic - power moving vehicle 8 is fixed at the bottom of the position - adjusting unit 6, and hydraulic inclined struts 9 are fixed on both sides of the automatic - power moving vehicle 8;

[0052] When the position - adjusting walking unit walks, the electromagnetic chucks 7 of the position - adjusting units 6 in the odd - numbered positions are magnetically adsorbed and tightly held with the channel steel 5 in advance, and the electromagnetic chucks 7 of the position - adjusting units 6 in the even - numbered positions are powered off. At the same time, the hydraulic inclined struts 9 of the position - adjusting units 6 in the even - numbered positions are tightly held with the ground. The power - moving vehicles of the position - adjusting units 6 in the odd - numbered positions walk, driving the channel steel 5 to walk synchronously. When the channel steel 5 travels to the set distance, the hydraulic inclined struts 9 of the position - adjusting units 6 in the odd - numbered positions are tightly held with the ground; the electromagnetic chucks 7 of the odd - numbered positions are powered off, and the electromagnetic chucks 7 of the even - numbered positions are powered on. Then, the hydraulic inclined struts 9 of the even - numbered positions retract, enabling the automatic - power moving vehicle 8 to drive the position - adjusting units 6 in the even - numbered positions to drive the channel steel 5 to walk linearly. After walking in place, the hydraulic inclined struts 9 of the even - numbered positions are controlled to extend, so that the hydraulic inclined struts 9 are tightly held with the ground again;

[0053] Guide seats 10, there are four groups of the guide seats 10, two groups of the guide seats 10 are fixed at both ends of the beam slab 1; the other two groups of the guide seats 10 are fixed at both ends of the channel steel 5;

[0054] Connecting bridge, the connecting bridge includes a front connecting bridge 11 and a rear connecting bridge 12. The front connecting bridge 11 is a frame - type structure with a hollow bottom. The front connecting bridge 11 is fitted with the two front - side guide seats 10 and fastened by bolts; the rear connecting bridge 12 includes a slope plate 13. One end of the slope plate 13 is integrally formed with a straight - track beam 14, and the other end is integrally formed with a straight beam 15. The straight - track beam 14 and the straight beam 15 are slidably fitted onto the two rear - end guide seats 10; a power system 16 is fixed inside the front connecting bridge 11;

[0055] After the connecting bridge and the guide seats 10 are fitted and locked by bolts, the tire - part limiting unit, the vehicle - body limiting unit, the position - adjusting walking unit and the connecting bridge can form a three - dimensional enclosing space. The front connecting bridge 11 serves as a supporting component for the power system 16; the slope plate 13 of the rear connecting bridge 12 can serve as a guiding part for the engineering vehicle to enter and exit the construction area; at the same time, it serves as an anti - collision support system;

[0056] Fixed walking unit, the fixed walking unit is arranged at both ends of the vehicle - body limiting unit. The fixed walking unit includes an adjusting box 17 fixed outside the guide seat 10. An elastic buffer unit 18 is arranged inside the adjusting box 17, and an automatic - power moving vehicle 8 is fixed at the bottom of the elastic buffer unit 18; when the position - adjusting walking unit walks, the fixed walking unit can walk synchronously, thereby driving the entire three - dimensional enclosing space to walk synchronously. The hydraulic inclined struts 9 of the fixed walking unit can serve as position limits for anti - collision deformation at the front end.

[0057] The load - unloading array includes a force - receiving platform 19 fixed to the beam - slab 1 by bolts. A blow - molding box 20 is fixed to the front side of the force - receiving platform 19. An impact platform 21 is arranged on the front side of the blow - molding box 20. Hinge seats 22 are fixed to the upper and lower parts on both sides of the force - receiving platform 19, the blow - molding box 20, and the impact platform 21. Arc - shaped steel bars 23 are hinged between adjacent hinge seats 22; the upper and lower arc - shaped steel bars 23 face in opposite directions; an elastomer is filled inside the blow - molding box 20; a right - angled opening is formed at the bottom of the support beam 4, and the right - angled opening is clamped to the top surfaces of the beam - slab 1 and the force - receiving platform 19; when the vehicle tire impacts the load - unloading array, it first contacts the impact platform 21, and the vehicle tire impacts the impact tire forward. At this time, due to the arc - shaped steel bar 23 being limited between the impact platform 21 and the force - receiving platform 19, the arc - shaped steel bar 23 undergoes elastic deformation, decomposing the impact force once until the impact platform 21 contacts the blow - molding box 20. When the blow - molding box 20 is impacted and deformed or damaged, the elastomer inside the blow - molding box 20 is extruded and deformed, decomposing the impact force a second time, which can fully decompose the impact force, protect the vehicle and the personnel inside the vehicle, and reduce the overall impact force of the protection space formed by the tire - part limiting unit, the vehicle - body limiting unit, the position - adjusting walking unit, and the connecting bridge.

[0058] The elastomer is foam glue, a spring array, or an airbag; the airbag is a filled spherical airbag or a mutually - pressed laminated airbag; when the blow - molding box 20 is impacted and damaged or deformed, the vehicle body contacts the elastomer, and thus, through the self - deformation of the foam glue, the spring array, or the airbag, the impact force can be further decomposed.

[0059] The automatic power mobile vehicle 8 includes a mobile vehicle body 24. A rolling groove is formed at the bottom of the mobile vehicle body 24. A traveling wheel 25 is rotatably installed inside the rolling groove through a bearing. The wheel axle of the traveling wheel 25 movably penetrates through the mobile vehicle body 24 and is fixed with a driven wheel. The driven wheel is connected to a driving wheel on a hydraulic motor 26 through a transmission member. The hydraulic motor 26 is fixed to the mobile vehicle body 24. The two sides of the mobile vehicle body 24 are integrally formed with inclined cylinder seats 27. The hydraulic strut 9 includes an oil cylinder 28 fixed inside the cylinder seat 27. A hinge ear seat 29 is fixed to the piston end of the oil cylinder 28. A toothed disc 30 is hinged to the hinge ear seat 29. When the automatic power mobile vehicle 8 travels, the hydraulic motor 26 drives the driving wheel to rotate. The driving wheel drives the traveling wheel 25 to rotate through the transmission member and the driven wheel. The traveling wheel 25 travels along the ground. The driving wheel, the transmission member and the driven wheel can adopt mutually meshing gears, a sprocket and chain structure, or a belt pulley and belt structure. When the traveling wheel 25 travels to a set position, the oil cylinder 28 acts to drive the hinge ear seat 29 to brace forward until the toothed disc 30 on the hinge ear seat 29 presses against the ground, and the gripping teeth on the toothed disc 30 press tightly against the ground, so that a stable triangular support state is formed among the mobile vehicle body 24, the ground and the hydraulic strut 9. When the channel steel 5 moves, due to the ground gripping of the toothed disc 30 of the hydraulic strut 9, the automatic power mobile vehicle 8 can be kept in this position unchanged until the hydraulic strut 9 retracts, and then it can freely travel along the channel steel 5. When the channel steel 5 is impacted, the hydraulic struts 9 of each automatic power mobile vehicle 8 respectively resist and decompose the impact force. And due to the ground gripping of the toothed disc 30 of the hydraulic strut 9, the impact of the anti-collision device is prevented from being overly displaced.

[0060] A plurality of proximity switches 31 are fixed on the channel steel 5. Whether the positioning unit 6 travels in place can be monitored in real time through the proximity switches 31. After traveling in place, the positioning unit 6 stops operating, and the hydraulic strut 9 is used for position locking and anti-collision support. The proximity switches 31 can adopt mechanical proximity switches 31 or infrared proximity switches 31. When the positioning unit 6 travels, first, the positioning unit 6 located at an odd position drives the channel steel 5 to travel. At this time, the positioning unit 6 located at an even position remains stationary. When the channel steel 5 travels, the proximity switch 31 on the channel steel 5 contacts the positioning unit 6 at the even position, and the positioning unit 6 at the odd position stops traveling. The hydraulic strut 9 performs position locking and anti-collision support. Then, the positioning unit 6 at the even position travels by itself until it actively contacts the proximity switch 31, and then the positioning unit 6 at the even position stops traveling. The hydraulic strut 9 performs position locking and anti-collision support.

[0061] The positioning unit 6 includes an inner pedestal 32 fixed to the top of the self-powered mobile vehicle 8 by bolts, and the electromagnetic chuck 7 is fitted and fixed on the inner pedestal 32; the inner pedestal 32 is fixed with adaptive cavity seats 33 on both sides along the traveling direction; a plurality of guide rods 34 are slidably arranged opposite to both sides of the adaptive cavity seat 33, and a limit nut is screwed on the inner side of the guide rod 34 in the adaptive cavity seat 33; the other end of the guide rod 34 is fixed to the roller seat 35, and a first spring 36 is sleeved between the opposite guide rods 34; a guide roller 37 is rotatably installed on the roller seat 35, and the guide roller 37 is movably pressed against both sides of the inner wall of the channel steel 5; four ends of the top of the inner pedestal 32 are fixed with ejector rods 38, a wheel seat 39 is sleeved on the ejector rod 38, and a second spring 40 is sleeved between the inner pedestal 32 and the wheel seat 39 on the ejector rod 38; a top wheel 41 is rotatably installed on the wheel seat 39, and the top wheel 41 abuts against the inner top of the channel steel 5; the self-powered mobile vehicle 8 supports the inner pedestal 32, the inner pedestal 32 serves as a support system for the guiding components of the channel steel 5 and as a mounting seat for the electromagnetic chuck 7; when the self-powered mobile vehicle 8 jolts during walking, by compressing or releasing the second spring 40, the top wheel 41 always fits against the top of the channel steel 5. When the top wheel 41 moves up and down, the wheel seat 39 is linearly guided by the ejector rod 38, so that the top wheel 41 closely fits against the inner top of the channel steel 5. And during the walking process of the self-powered mobile vehicle 8, due to the action of the first spring 36, the guide rod 34 is pushed outwards, so that the roller seat 35 is pushed outwards by the guide rod 34, and the guide roller 37 always contacts both sides of the inner wall of the channel steel 5.

[0062] The elastic buffer unit 18 includes a support body 42 fixed to the top of the self-powered mobile vehicle 8, a guide rod 43 is fixed to the top of the support body 42, the guide rod 43 movably passes through the adjustment box 17 and is screwed with a top nut; a third spring 44 is arranged between the inner top of the adjustment box 17 and the support body 42 on the guide rod 43; the elastic buffer unit 18 can automatically adapt to ground fluctuations. When the self-powered mobile vehicle 8 jolts during walking, the support body 42 jacks up and compresses the third spring 44, or releases the pressure of the third spring 44, so that the self-powered mobile vehicle 8 always fits against the ground.

[0063] Angle seats 45 are fixed to the lower parts of both sides of the channel steel 5, a wheel seat 39 is fixed to the angle seat 45 through a damping rod 46, and a first follower walking wheel 47 is installed on the wheel seat 39; the angle seat 45, the damping rod 46 and the first follower walking wheel 47 can support both sides of the channel steel 5, so that the channel steel 5 is always supported on the ground. When the channel steel 5 walks, the first follower walking wheel 47 can follow, and the damping rod 46 automatically adapts to the ground, so that the first follower walking wheel 47 always fits against the ground.

When the vehicle enters and exits and presses on the slope plate 13, it will not cause the deformation of the rear connecting bridge 12. Specifically: the rear guide seat 48 is fixed to the guide seat 10, the rear guide seat 48 slides up and down with the straight rail beam 14, and the straight beam 15 of the rear connecting bridge 12 and the guide seat 10 can be assembled by a sleeve type, a dovetail guide rail type or a hook type, and the straight beam 15 is assembled to the guide seat 10; when the vehicle body limiting unit is impacted, the impact force is transmitted to the position adjustment traveling unit through the stress support platform 49 and the guide seat 10.

When the anti-collision device is impacted, the two ends of the barrier rod can limit between the vehicle body limiting unit and the position adjustment traveling unit; thus, a three-dimensional space anti-impact is formed by the barrier rod and the slope plate 13. When there are construction vehicles entering and exiting the construction area, the barrier rod of the electric barrier 52 is lifted, and the vehicle can enter and exit the construction area smoothly.

[0067] Embodiment 3:
