Description

Technical Field

[0001] The present application relates to the technical field of road safety protection devices, and specifically discloses a protection device for road engineering. Background Art

[0002] Roads were created alongside human activities and have contributed to social progress and development. They are a symbol of historical civilization and a hallmark of scientific advancement. Road engineering refers to the entire process of planning, design, construction, maintenance, and management of roads, as well as the engineering entities involved.

[0003] Road engineering mainly includes the following branches: roadbed engineering, pavement engineering, road drainage engineering, etc. Among them, roadbed engineering and pavement engineering are both road surface construction.

[0004] In the existing technology, the road construction process mainly includes the following steps: measuring the roadbed, removing the original asphalt concrete or other road fillers, paving new fillers, and then rolling the fillers to make them flat and complete the solidification step to ensure that the road surface meets the requirements for use.

[0005] During road construction, pedestrians and other non-operational vehicles are not allowed to travel on roads that are under construction, awaiting construction, or have not yet been completed. Therefore, during road construction, it is necessary to set up isolation and protection devices outside the road to be constructed to isolate the road to be constructed from the surrounding environment, or to set up signs before and after the road to be constructed to warn pedestrians and other non-operational vehicles.

[0006] In existing technology, protective devices and signs are bolted directly to the ground, with a barrier used to display a warning or directly isolate the area. At night, at the beginning of the road under construction, where visibility is low, motorcycles, pedestrians, and vehicles may collide with the barrier and drive onto the road. Barriers secured solely by bolts provide insufficient support.

[0007] Therefore, in view of this, the inventor provides a protective device for road engineering to solve the above problems. Summary of the Invention

[0008] The purpose of the present invention is to solve the problem that the conventional road protection structure is prone to collapse due to its unstable bolt connection structure when it is hit.

[0009] To achieve the above-mentioned object, the basic solution of the present invention provides a road engineering protective device, comprising a baffle, supporting base plates provided on both sides of the baffle, mounting seats slidably connected to the supporting base plates and used for mounting the baffle, latches detachably connected to the supporting base plates and used to prevent the mounting seats from moving back, fixing base plates respectively fixed to the outer sides of the supporting base plates, and fixing assemblies respectively provided on the fixing base plates;

[0010] A supporting structure for supporting the mounting seat is provided on the supporting base plate inside the baffle;

[0011] A transmission box is also provided on the fixed base plate between the fixed assembly and the mounting seat;

[0012] The fixed assembly includes a fixed driving seat fixedly connected to the fixed base plate, a fixed transmission seat and a fixed pile driven by the fixed transmission seat and screwed into the ground;

[0013] A transmission structure is provided in the transmission box, a driving structure is provided in the fixed driving seat and is driven by the transmission structure and outputs drive to the fixed driving seat, and a power structure is provided under the mounting seat to provide power to the transmission structure.

[0014] Furthermore, the bottom end of the fixed pile is a conical tip, a smooth surface is left on a section of the fixed pile near the tip, and the remaining fixed pile is provided with an external thread. The fixed transmission seat includes a fixed sleeve and a transmission sleeve that is coaxially arranged in the fixed sleeve and driven by the driving structure, and an internal thread that engages with the external thread is provided in the transmission sleeve.

[0015] Furthermore, the support structure includes a sliding sleeve rotatably connected to the support base plate, a sliding rod slidably connected to the sliding sleeve and used to support the mounting seat, and a clamping member that can be inserted between the end opening of the sliding sleeve and the sliding rod.

[0016] Furthermore, the clamping piece includes a left clamping block and a right clamping block that can be closed to each other. When the left clamping block and the right clamping block are closed, a through hole is left for the sliding rod to pass through but the diameter is smaller than the diameter of the sliding rod, and the end opening of the sliding sleeve is provided with an inwardly inclined inclined groove.

[0017] Furthermore, a plurality of driven clamping rings are equidistantly provided on the outer wall of the slide rod, and a plurality of active clamping rings are also provided between the left clamping block and the right clamping block, which can be respectively clamped into the gaps between the driven clamping rings.

[0018] Furthermore, the active clamping ring gradually deepens in the direction extending from the top end to the end end of the clamping member.

[0019] Furthermore, an isolation fence is fixed to the inner side of the support base, and several traction ropes are detachably connected to the front end face of the baffle. A wire supply groove for the traction rope to pass through is opened on the isolation baffle facing the front of the baffle, and a traction structure for fixing the traction rope is provided on the support base located behind the baffle.

[0020] Furthermore, the support base plate is also provided with a retractable structure for retracting and releasing the traction rope.

[0021] Furthermore, the retractable structure includes a traction gear driven by a transmission structure, a traction shaft coaxially connected to the traction gear, and a traction wheel slidably arranged on the traction shaft. The traction shaft is circumferentially provided with latching teeth, and the bottom of the traction wheel is provided with a positioning groove that can be engaged with the latching teeth.

[0022] Furthermore, the traction structure includes a main branch line clamp rotatably connected to the end of the supporting base plate and an auxiliary branch line clamp clamped with the main branch line clamp. The main branch line clamp and the auxiliary branch line clamp can also be fixed by bolts. The auxiliary branch line clamp is provided with an entry hole, and a branch line groove connected to the entry hole is provided between the main branch line clamp and the auxiliary branch line clamp. The end faces of one side of the main branch line clamp and the auxiliary branch line clamp are also provided with branch line holes respectively connected to the branch line grooves. The diameters of the branch line grooves and the branch holes are both smaller than the diameter of the traction rope.

[0023] The principle and effect of this solution are:

[0024] 1. During the road construction process, the present invention places the device at the front end of the road to be constructed, and supports the left and right sides of the baffle through the supporting base plate and the mounting seat. In the process of sliding the mounting seat and the baffle backward, the sliding is transmitted to the transmission structure through the power structure, and the transmission structure drives the driving structure to output to the fixed transmission seat, and the fixed pile is driven by the fixed transmission seat to screw into the ground, completing the fixation and support of the entire device, and then the positioning of the front end of the baffle is completed by the pin. When the baffle is hit, the baffle will move backward, which will further drive the fixing pile to screw in, further stabilizing the support, and solving the problem that the traditional road protection structure is not stable enough when hit by its bolt connection structure, and the protection structure is easy to fall over.

[0025] 2. The present invention first places the supporting base plate and the fixed base plate on the ground at the front end of the road to be constructed or on the ground at the starting end of the road to be constructed, and then fixes the baffle in the initial position through the mounting seat, and then places the fixed pile into the fixed transmission seat. After that, the baffle is pushed backward to the predetermined position. In the process of pushing the baffle, the fixed pile will be gradually screwed in to complete the fixation of the entire device, and then the support structure completes the support and fixation between the baffle and the supporting base plate.

[0026] 3. In the support structure of the present invention, when the baffle is hit and slides backward, the driven clamping ring on the slide rod will be limited by the main clamping ring between the left clamping block and the right clamping block, and will drive the left clamping block and the right clamping block to move further toward the inclined groove in the sliding sleeve, thereby further tightening the slide rod and strengthening the support.

[0027] 4. The traction structure and the retractable structure provided in the present invention can play a role in assisting the support of the baffle when the baffle is stationary, and can play a role in stabilizing the baffle when the baffle is hit. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0036] The reference numerals in the drawings of the specification include: baffle 1, supporting base plate 2, isolation fence 3, transmission box 4, fixed base plate 5, seat back 6, slide rod 7, sliding sleeve 8, clamping part 9, fixed sleeve 10, fixed drive seat 11, fixed pile 12, traction seat 13, auxiliary branch line clamp 14, traction rope 15, reinforcement rib 16, power plate 17, transmission belt 18, secondary input gear 19, traction gear 20, traction wheel 21, main bevel gear 22, output pulley 23, and transmission sleeve 24.

[0037] A protective device for road engineering, for example Figure 1 As shown:

[0038] The system comprises a baffle 1, two supporting bases 2 mounted on either side of the baffle 1, each of which is equipped with a mounting base for the baffle 1. A fixed base 5 is mounted on the outside of each supporting base 2. Two sets of fixing components are mounted on the outside of each fixing base 5, and a transmission box 4 is mounted on the fixing base 5 between the two sets of fixing components and the mounting base.

[0039] like Figure 1 and Figure 2 As shown, a ridge shaped boss is integrally formed on both ends of the baffle 1. A reinforcing platform is also integrally formed on the baffle 1 on the inner side of the boss. Five reinforcing ribs 16 are welded on the front and back of the baffle 1.

[0040] The mounting base comprises a body and a back 6. The body is provided with a groove for accommodating the bosses at both ends of the baffle 1. The bosses at both ends of the baffle 1 can slide downward into the grooves on the body and can be fixed between the supporting base plates 2 on both sides through the body. The back 6 is arranged at the rear of the body. When the ends of the baffle 1 slide into the grooves, the back 6 abuts against the back of the ends of the baffle 1, supporting the baffle 1 when it tends to fall backward.

[0041] A number of support positioning holes are equidistantly provided on both sides of the seat back 6, and the support positioning holes on both sides are parallel to each other. A shift chute is also provided on the support base, and a shift plate is installed in the shift chute. A parallel limit groove is provided on the inner side wall of the shift chute, and a limit block that can slide in the limit groove is also integrally formed on the inner side of the shift plate. The top of the shift plate extends out of the shift chute and is fixedly installed on the lower end face of the seat body. After the mounting seat and baffle 1 slide to the predetermined position, a pin is inserted into the mounting seat, baffle 1, and the front end of the shift plate to prevent the baffle 1 from moving back. A rotating support seat is also installed on the support base plate 2 behind the end of the shift chute. A traction seat 13 is also installed on the support base plate 2 behind the rotating support seat.

[0042] The end of the rotating support seat near the shifting chute is an inclined platform that gradually tilts and approaches the upper end surface of the support base plate 2. A rotation groove is opened from the inclined platform into the rotating support seat. A support fixing plate is installed on the rear of the two seat backs 6 by supporting positioning holes and bolts. A support fixing platform is welded on both sides of the support fixing plate. A rod support shaft is installed between the two support fixing platforms. A tube support shaft is also installed on the inner walls of both sides of the rotation groove. A sliding rod 7 is connected through the rod support shaft. A sliding sleeve 8 is installed through the tube support shaft. The sliding rod 7 can slide into the sliding sleeve 8. Specifically, the ends of the sliding rod 7 and the sliding sleeve 8 each have an axial hole. The sliding rod 7 and the sliding sleeve 8 are respectively installed on the rod support shaft and the tube support shaft through the axial hole, and both can rotate.

[0043] like Figure 6As shown, the top end of the sliding sleeve 8 has an inwardly extending beveled groove. Several driven retaining rings are equidistantly positioned on the sliding rod 7 from the bottom end toward one end of the rod support shaft. A clamping member is also mounted on the outside of the sliding rod 7, positioned within the beveled groove at the top end of the sliding sleeve 8. The clamping member comprises two interconnected parts: a left clamping block and a right clamping block. The end surfaces of the left and right clamping blocks are alternately provided with grooves and keys. When fitted together, the grooves and keys on the ends of the left and right clamping blocks engage with each other, allowing the ends of the left and right clamping blocks to fit snugly. Furthermore, the outer walls of the left and right clamping blocks are tapered, with the same inclination angle as the beveled groove. Furthermore, the diameters of the left and right clamping blocks increase from bottom to top to a diameter greater than the diameter of the beveled groove within the sliding sleeve 8. The outer walls of the left and right clamping blocks, located outside the sliding sleeve 8, each have a shifting groove. When the left and right clamping blocks are closed, a through-hole is left to accommodate and pass through the slide rod 7. Several active snap rings are positioned within the through-holes, positioned between the gaps between the driven snap rings. In this example, the active snap rings, positioned from top to bottom of the clamping member, gradually protrude outward, and both the active and driven snap rings are rubber rings.

[0044] After installing the baffle 1 and completing the pre-installed installation and inserting the latches for positioning, the mounting height of the fixed support plate is selected, and the support angles for the slide bar 7 and sleeve 8 are determined. The left and right clamping blocks are then placed at the ends of the sleeve 8, wrapping around the slide bar 7. The active clamping ring is inserted between the gaps between the driven clamping ring and the left and right clamping blocks. The clamping member formed by the left and right clamping blocks is then hammered into the angular groove of the sleeve 8. This method supports and secures the baffle 1. When the baffle 1 is impacted, the backward impact force is transmitted to the slide bar 7 and distributed to the driven and active clamping rings. Because the active clamping ring at the inlet of the clamping member is looser than the active clamping ring at the outlet, the slide bar 7 can drive the driven clamping ring into the clamping member as the impact force is applied. The deformation of the rubber ring disperses and cushions the impact force. Simultaneously, as the slide bar 7 moves inward, it also drives the clamping member into the angular groove, further tightening the slide bar 7 and further stabilizing the support of the baffle 1.

[0045] like Figure 2 and Figure 5 As shown, the fixing components installed on the outside of the fixing plate include a fixed driving seat 11, a fixed transmission seat and a fixed pile 12 installed by the fixed transmission seat and driven into the ground by the fixed transmission seat.

[0046] In this embodiment, the fixed transmission seat is obliquely mounted on the left end portion of the fixed drive seat 11 , and the oblique direction of the fixed transmission seat is the same as the direction in which the baffle 1 is struck.

[0047] like Figure 5As shown, the fixing pile 12 is cylindrical as a whole, and the bottom of the fixing pile 12 is a conical tip. A smooth surface is left on the fixing pile 12 near the tip, and the remaining fixing pile 12 has an external thread from the top downward.

[0048] The fixed transmission seat comprises a fixed sleeve 10 and a transmission sleeve 24 mounted within the fixed sleeve 10. The fixed post 12 is coaxially mounted with the fixed sleeve 10 and the transmission sleeve 24. The outer diameter of the transmission sleeve 24 is smaller than that of the fixed sleeve 10, while the inner diameter of the transmission sleeve 24 is larger than that of the fixed sleeve 10. Within the fixed sleeve 10, a primary annular groove is defined for coaxial rotation of the transmission sleeve 24. Both ends of the primary annular groove are formed inwardly with closed secondary annular grooves. Secondary sliders are integrally formed at each end of the transmission sleeve 24, each of which slides within the secondary annular grooves. The inner wall of the transmission sleeve 24 has internal threads that engage with the external threads on the fixed post 12, and the outer wall of the transmission sleeve 24 has a ring of transmission teeth. A transmission groove is defined within a section of the outer wall of the fixed sleeve 10 located within the fixed drive seat 11. The transmission groove communicates with the primary annular groove and exposes a section of transmission teeth mounted on the outer wall of the transmission sleeve 24.

[0049] After the fixing stake 12 is inserted into the fixing sleeve 10, the tip and the smooth surface behind the tip will slide across the transmission sleeve 24. The external threads on the fixing stake 12 are blocked from further downward movement by the internal threads of the transmission sleeve 24. Only by rotating the transmission sleeve 24 and engaging the internal and external threads can the fixing stake 12 be screwed in further downward. During this downward screwing process, the tip of the fixing stake 12 breaks through the soil layer, extending into the soil and securing it.

[0050] In this embodiment, a transmission structure is mounted within the transmission case 4. A set of drive structures driven by the transmission structure is mounted within the fixed drive base 11. A power structure for providing power to the transmission structure is mounted on the shift plate. The power structure drives the transmission structure, causing the drive structure to move. The drive structure then drives the transmission sleeve 24 to rotate, driving the fixed pile 12 into the soil layer, thereby securing the support base plate 2 and the baffle 1.

[0051] Specifically, a power chute is provided within the support base plate 2 below the shift chute, extending through the outer end surface of the support base plate 2. A power channel connecting to the power chute is also provided within the transmission case 4. The power structure mounted on the shift plate comprises a power plate 17 fixedly mounted at the bottom of the shift plate and extending into the transmission case 4 via the power chute and channel. A number of power teeth are equidistantly provided on the sidewall of the power plate 17 within the transmission case 4.

[0052] The transmission structure, housed within transmission case 4, consists of two axles, two coaxially mounted wheels, and a transmission belt 18 wound between the wheels. The outer end surface of transmission belt 18 is provided with a number of equally spaced teeth and grooves. Support plates are also installed within transmission case 4 on the inside of transmission belt 18 to support and prevent it from collapsing. Power teeth on power plate 17 mesh with the teeth and grooves on transmission belt 18.

[0053] The driving structure installed in the fixed driving seat 11 includes: a primary input member driven by the transmission structure, a step-by-step amplification transmission member driven by the primary input member, and a primary output member driven by the step-by-step amplification transmission member and driving the transmission sleeve 24 to rotate.

[0054] The primary input component includes a first input shaft, a primary input gear coaxially mounted on the first input shaft, a second input shaft, a main input pulley coaxially mounted on the second input shaft, a secondary input gear 19 coaxially mounted on the second input shaft, a third input shaft, a secondary input pulley coaxially mounted on the third input shaft, and a main bevel gear 22 coaxially mounted on the third input shaft. The secondary input gear 19 meshes with the primary input gear, and an input belt is wound between the main and secondary input pulleys. A drive slot is defined in the fixed drive base 11, communicating with the interior of the transmission case 4. The primary input gear extends through the drive slot into the transmission case 4 and meshes with the teeth on the transmission belt 18. The first, second, and third input shafts are all rotatably mounted.

[0055] The graded amplifying transmission element includes a first graded rotating shaft, a first graded main pulley coaxially mounted on the first graded rotating shaft and a secondary bevel gear coaxially mounted on the first graded rotating shaft, a second graded rotating shaft, a second graded main pulley coaxially mounted on the second graded rotating shaft and a first graded secondary pulley coaxially mounted on the second graded rotating shaft, a third graded rotating shaft, a third graded main pulley coaxially mounted on the third graded rotating shaft and a second graded secondary pulley coaxially mounted on the third graded rotating shaft.

[0056] The first, second, and third stage rotating shafts are all mounted for tilted rotation, and the tilt direction is the same as the tilted mounting direction of the fixed pile 12, fixed sleeve 10, and transmission sleeve 24. The secondary bevel gear meshes with the main bevel gear 22. A first stage belt is wound between the first stage primary pulley and the first stage secondary pulley, a second stage belt is wound between the second stage primary pulley and the second stage secondary pulley, and a third stage belt is wound between the third stage primary pulley and the third stage secondary pulley.

[0057] The primary output member includes a primary output shaft, an output pulley 23 coaxially connected to the primary output shaft, and a third graded secondary pulley coaxially connected to the primary output shaft.

[0058] A third grading belt is wound between the third grading primary pulley and the third grading secondary pulley. The outer wall of the output wheel 23 is provided with a plurality of output teeth, which mesh with the transmission teeth on the outer wall of the transmission sleeve 24.

[0059] During the installation and fixing of the baffle 1, when the baffle 1 is slid inward, it drives the mounting base and the shift plate to slide inward, thereby driving the power gears on the power plate 17 to shift the transmission belt 18 in the transmission box 4. As the transmission belt 18 rotates, the transmission belt 18 meshes with the first-stage input gear through the tooth groove, causing the first-stage input member to move. The meshing between the belt drive and the bevel gear drives the step-by-step amplification transmission member to move. The belt drive 18 then drives the first-stage output member to move. The output teeth on the output wheel 23 mesh with the transmission teeth on the outer wall of the transmission sleeve 24, driving the rotation of the transmission sleeve 24. The internal thread of the transmission sleeve 24 meshes with the external thread of the fixed pile 12, screwing the fixed pile 12 in. The fixed pile 12 can be screwed in by sliding the baffle 1, and the screwing depth of the fixed pile 12 is controlled by the sliding feed of the baffle 1. Of course, during use, the baffle 1 is always located near the end of the shift chute.

[0060] During use, the fixed pile 12 and support base 2 provide support for the entire structure, while the slide bar 7, sleeve 8, and clamping member support the baffle 1. When the baffle 1 is impacted, it slides backward. At this point, the slide bar 7 pushes further into the clamping member and sleeve 8, with the active snap ring on the clamping member and the passive snap ring on the slide bar 7 acting as a first buffer and limiter. Secondly, the inward sliding of the baffle 1 drives the power plate 17 inward, which in turn activates the transmission belt 18, which in turn drives the transmission and drive structures, and in turn drives the transmission sleeve 24 to rotate, further screwing into the fixed pile 12 to provide additional support.

[0061] During disassembly, one only needs to pull out the clamping member and the latch, and then push the baffle 1 outward, which will drive the transmission sleeve 24 to rotate in the opposite direction, thereby unscrewing the fixing pile 12, thus reducing installation and disassembly time. If the baffle 1 is hit, there is no need to dismantle the entire device; only the baffle 1 needs to be pulled out and replaced before it can be put back into use.

[0062] like Figure 1As shown, an isolation fence 3 is also installed on the inner side of the support base 2. A wire feed groove is also opened on the isolation fence 3 near the starting end, and the inner wall of the wire feed groove is rounded for transition. A set of traction structures is installed in the traction seat 13. The traction structure includes a rotatable traction shaft, a traction gear 20 coaxially mounted on the traction shaft, and a traction wheel 21 mounted on the traction shaft. The traction wheel 21 is installed above the traction gear 20, and a traction groove is opened between the traction seat 13 and the transmission box 4. The traction gear 20 extends into the transmission box 4, and the traction gear 20 engages with the tooth groove on the transmission belt 18 in the transmission box 4.

[0063] A circle of evenly spaced latching teeth is integrally formed on the outer wall of the traction shaft above the traction gear 20. A positioning slot for the latching teeth is provided on the traction wheel 21. In this embodiment, three traction ropes 15 are wound around the traction wheel 21, and a through hole for the traction ropes 15 to pass through is provided on the right side of the traction seat 13.

[0064] A rotatable pull-cord structure is also mounted at each end of the support base 2. A rectangular slot is defined at the end of the support base 2 to accommodate the pull-cord structure. The pull-cord structure comprises a rotatable rod mounted between the slots, a main branch clamp fixed to the rod, and a secondary branch clamp 14 that engages with the main branch clamp. Once engaged, the main and secondary branch clamps 14 are further secured with bolts.

[0065] In this embodiment, the length of the isolation fence 3 is shorter than that of the supporting base plate 2. A threaded hole is formed on both sides of the rectangular groove on the supporting base plate 2, and a similar threaded hole is formed on the rotating rod.

[0066] A secondary branching clamp 14 has a wire entry hole and three secondary branching slots, each connected to the entry hole. Three secondary branching holes are also located on the inner side of the secondary branching clamp 14, each connected to the secondary branching slot. The main branching clamp also has three main branching slots and holes corresponding to the secondary branching slots and holes on the secondary branching clamp 14. When the main branching slots and secondary branching slots, and the main branching holes and secondary branching holes are combined, the size and diameter of the slots are smaller than the diameter of the traction rope 15. This means that when the secondary branching clamp 14 and the main branching clamp are combined, the traction rope 15 can be clamped securely.

[0067] During use, after the baffle 1 is installed and before it is moved, and after the fixing pile 12 is placed, the traction wheel 21 is pulled upward to separate the positioning groove and the latch on the traction wheel 21. Then, the traction rope 15 on the traction wheel 21 is pulled out and inserted into the wire entry hole of the auxiliary branch clamp 14. After the three strands of traction rope 15 are separated and placed in the corresponding auxiliary branch grooves, the three traction ropes 15 that have passed through the branch holes are further pulled out and passed from under the isolation fence 3 to the wire supply groove. Three fixed coils are also installed on both sides of the front end of the baffle 1 from top to bottom. The three traction ropes 15 are respectively fixed to the fixed coils. After fixing is completed, the traction wheel 21 is inserted downward to place the latch in the positioning groove, so that the traction wheel 21 can rotate synchronously with the traction shaft.

[0068] When the traction rope 15 is fixed, the baffle 1 can be pushed backward. In the process of pushing the baffle 1, the fixing pile 12 can be screwed in and the traction wheel 21 can be rotated to rotate the traction rope 15 out. When the baffle 1 moves to a predetermined distance, it can stop moving and insert the pin into the shifting slot in front of the baffle 1. At this time, the fixing pile 12 is basically immersed in the fixing sleeve 10. Then, the clamping piece is inserted between the slide bar 7 and the sliding sleeve 8 to fix the baffle 1. After the clamping piece is inserted, the auxiliary branch line clamp 14 and the main branch line clamp are combined and fixed by bolts. The traction rope 15 can be clamped by the auxiliary branch line clamp 14 and the main branch line clamp. After that, the main branch line clamp and the auxiliary branch line clamp 14 are rotated to rotate the rotating rod. After the rotating rod is rotated until the traction rope 15 is tightened, the bolt can be screwed into the bolt hole to complete the fixation of the rotating rod, that is, to further support and fix the baffle 1.

[0069] Before the road construction process is carried out, the baffle 1 is installed at the front end of the road to be constructed. When the baffle 1 is hit, the baffle 1 will move backward due to the impact. After the baffle 1 moves backward, the force will be transferred to the slide bar 7, and will be buffered by the clamping member 9 and the sliding sleeve 8. The backward movement of the baffle 1 will further screw into the fixed pile 12 to further stabilize the overall support of the device. The backward movement of the baffle 1 will pull the traction rope 15. The traction rope 15 is clamped by the main branch line clamp and the auxiliary branch line clamp 14 and fixed by bolts. It can pull the baffle 1 that has a tendency to tilt backward. When the baffle 1 is hit too hard and the bolts fail, the main branch line clamp and the auxiliary branch line clamp 14 will be pulled downward. Due to the obstruction of the ground and the supporting base plate 2, it can also play a partial supporting role.

[0070] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
