Description

Technical Field

[0001] This application relates to the field of road engineering, and in particular to an anchor-free highway guardrail that is easy to install and remove. Background Technology

[0002] Guardrails are traffic safety facilities installed on the outer side of road shoulders, traffic dividers, and pedestrian curbs. The main function of highway guardrails is to prevent vehicles from running off the road and to guide vehicles.

[0003] With the rapid development of my country's economy and modernization, many old highways can no longer handle current passenger traffic. Furthermore, highway construction is costly and time-consuming. Therefore, widening and upgrading existing highways has become the mainstream approach. However, ensuring the safety of construction workers is crucial when widening and upgrading existing highways.

[0004] Anchor-free highway guardrails have advantages such as high independence, convenient construction, and repositionable design. Utility model patent CN221702217U discloses an anchor-free guardrail, comprising a concrete base, concrete counterweights, guardrail square tube posts, and anti-glare panel square tube posts. Several concrete bases are fixedly connected end-to-end and placed on the road surface. Concrete counterweights are fixedly placed on the concrete bases. The guardrail square tube posts pass through the concrete counterweights and are fixedly inserted into the concrete bases. M-plates are fixedly connected to both sides of the guardrail square tube posts. The anti-glare panel square tube posts pass through the concrete counterweights and are fixedly inserted into the concrete bases. Anti-glare panels are fixedly connected to the anti-glare panel square tube posts.

[0005] In the above scheme, the heavy concrete base is placed directly on the road surface. The stability of its placement is ensured by the large friction force generated by its own weight. However, due to its heavy weight, operations such as transportation, installation and dismantling will inevitably require the assistance of lifting equipment, otherwise it will be difficult to complete. It is highly dependent on specific objective conditions. Summary of the Invention

[0006] To address the aforementioned issues, this application provides an anchor-free highway guardrail that is easy to assemble and disassemble.

[0007] The present application provides a convenient and easy-to-assemble anchor-free highway guardrail using the following technical solution:

[0008] An anchor-free highway guardrail that is easy to assemble and disassemble includes a main body base and a guardrail plate. The guardrail plate is connected above the main body base and the two are parallel in length. An adjusting block is slidably mounted on the main body base in a vertical direction. A motorized wheel is rotatably mounted on the adjusting block, and the axis of the motorized wheel is horizontal. An adjusting mechanism is provided on the main body base to control the movement of the adjusting block. When the adjusting block is at its highest point of travel, the main body base is in contact with the ground, and there is a gap between the wheel surface of the motorized wheel and the ground. When the adjusting block is at its lowest point of travel, the wheel surface of the motorized wheel is in contact with the ground, and there is a gap between the main body base and the ground.

[0009] Preferably, the adjustment mechanism includes an initial position spring, one end of which is connected to the main body seat and the other end is connected to the adjustment block. The initial position spring applies an upward pulling force to the adjustment block, and in its natural state, the adjustment block is located at the highest point of its own stroke.

[0010] Preferably, the adjustment mechanism further includes a control column and a control push block. The control push block is slidably connected to the main body long seat, and the sliding direction is horizontal. The adjustment block is provided with a force-bearing wedge surface. When the control push block moves, it applies a pushing force to the force-bearing wedge surface. The control column is vertically inserted into the main body long seat. The control column includes a driving part. The cross-section of the driving part is non-circular. The edge of the driving part contacts the end of the control push block away from the adjustment block.

[0011] Preferably, the main body has a control hole slot for inserting the control column, and a guide wheel is rotatably connected to the wall of the control hole slot. The rotation axis is perpendicular to the depth direction of the control hole slot. The side wall of the control column has a guide groove for the guide wheel to enter, and the wheel surface of the guide wheel makes rolling contact with the groove wall of the guide groove.

[0012] Preferably, the guide groove includes a first slide and a second slide connected in sequence. The length direction of the first slide is parallel to the length direction of the control column, and the length direction of the second slide is the circumferential direction of the control column. The second slide has a first position and a second position. When the guide wheel is located in the second slide, the drive unit and the control push block are at the same height. When the guide wheel is located in the first position, there is a gap between the control push block and the drive unit. When the guide wheel is located in the second position, the drive unit abuts against the control push block and causes the adjusting block to move down, and the wheel surface of the motor wheel contacts the ground.

[0013] Preferably, the control column has a lever through hole, the length direction of the lever through hole is radial to the control column, and the lever through hole passes through opposite sides of the control column.

[0014] Preferably, the guardrail plates are arranged in two rows side by side and located on opposite sides of the control posts. The two rows of guardrail plates are fixed by tie rods that pass through the lever holes. The length of a single guardrail plate is greater than the distance between two adjacent control posts.

[0015] Preferably, a relay block is rotatably connected to the bottom of the adjusting block, the rotation axis is vertical, and the motor wheel is rotatably connected to the relay block.

[0016] This application includes at least one of the following beneficial technical effects:

[0017] 1. By setting an adjustment block with motorized wheels, when the main body long seat needs to be placed stably, the adjustment block is moved up to retract the adjustment wheel. When the main body long seat needs to be moved, the adjustment wheel is moved down to contact the ground and the main body long seat is relatively suspended in the air. This makes it easy to move the main body long seat, greatly improving the convenience of moving the adjustment long seat and reducing the dependence on heavy machinery.

[0018] 2. The lever through-hole allows pry bars or similar tools to be passed through the control post, facilitating manual rotation control of the post. Simultaneously, the lever through-hole allows tie rods to pass through, enabling the installation of the guardrail long plate via the control post. Furthermore, the installed guardrail long plate can prevent rotation and limit the control post, improving the stability of the main body. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses an anchor-free highway guardrail that is easy to assemble and disassemble, such as... Figure 1 As shown, the system includes multiple main long seats 1 and multiple guardrail long plates 2. The main long seats 1 are concrete components, rectangular in shape, and are arranged sequentially along their length. The guardrail long plates 2 are installed above the main long seats 1, and their length direction is parallel to that of the main long seats 1. The guardrail long plates 2 are thin plates with an M-shaped cross-section.

[0028] like Figure 1 and 2 As shown, an adjusting block 3 is vertically slidably mounted on the main body long seat 1, and a motor wheel 32 is rotatably mounted on the adjusting block 3. The axis of the motor wheel 32 is horizontal. An adjusting mechanism 4 is provided on the main body long seat 1, which is used to control the movement of the adjusting block 3. The movement control mechanism of the adjusting block 3 is as follows: when the adjusting block 3 is at the highest point of its stroke, the bottom of the main body long seat 1 is in direct contact with the ground of the road, and there is a gap between the wheel surface of the motor wheel 32 and the ground, i.e., no contact; when the adjusting block 3 is at the lowest point of its stroke, the wheel surface of the motor wheel 32 is in contact with the ground, and there is a gap between the main body long seat 1 and the ground, i.e., the adjusting block 3 lifts the main body long seat 1, and at the same time, the motor wheel 32 is in direct contact with the ground, so that the main body long seat 1 can easily move its position on the ground.

[0029] like Figure 1-3 As shown, the adjustment mechanism 4 includes an initial position spring 41 and a control push block 42. One end of the initial position spring 41 is connected to the main body long seat 1, and the other end is connected to the adjustment block 3. Its extension and contraction direction is vertical. The initial position spring 41 applies an upward pulling force to the adjustment block 3. In its natural state, the adjustment block 3 is located at the highest point of its stroke. The control push block 42 is slidably connected to the main body long seat 1. The sliding direction is horizontal. The adjustment block 3 is provided with a force-receiving wedge surface 33. The end of the control push block 42 facing the adjustment block 3 is rotatably connected to a propulsion roller 421. The rotation axis is horizontal. When the control push block 42 moves, the roller surface of the propulsion roller 421 abuts against the force-receiving wedge surface 33, thereby applying a pushing force to the force-receiving wedge surface 33. Under the decomposition of the force on the wedge surface, the adjustment block 3 can move downward.

[0030] like Figure 1-3 As shown, the control column 43 is vertically inserted into the main body long base 1. The control column 43 includes a cylindrical part 431 and a driving part 432. The driving part 432 is located at the lower end of the cylindrical part 431. The cross-section of the cylindrical part 431 is circular, while the cross-section of the driving part 432 is non-circular. The main body long base 1 has a control hole slot 11 for the control column 43 to be inserted. The cross-section of the control hole slot 11 is the same in shape and size as the cross-section of the cylindrical part 431. The end of the control push block 42 away from the push roller 421 is located in the control hole slot 11. When the control column 43 is inserted into the control hole slot 11, the driving part 432 is at the same height as the control push block 42.

[0031] like Figure 1-3 As shown, a guide wheel 12 is rotatably connected to the wall of the control slot 11, with its rotation axis perpendicular to the depth direction of the control slot 11. A guide groove 44 is provided on the side wall of the control column 43. When the control column 43 is inserted into the control slot 11, the guide wheel 12 will enter the guide groove 44, and the wheel surface of the guide wheel 12 will roll into contact with the wall of the guide groove 44. The guide groove 44 includes a first slide rail 441 and a second slide rail 442 connected in sequence. The length direction of the first slide rail 441 is parallel to the length direction of the control column 43, and the length direction of the second slide rail 442 is circumferential to the control column 43. The second slide rail 442 is located at the upper end of the first slide rail 441, so that when the guide wheel 12 is located in the first slide rail 441, the control column 43 can only move vertically, and when the guide wheel 12 is located in the second slide rail 442, the control column 43 can only rotate.

[0032] like Figure 2-6 As shown, when the guide wheel 12 moves to the second slide rail 442, the drive unit 432 and the control push block 42 are at the same height. During the entire process of the guide wheel 12 being located in the first slide rail 441, the control push block 42 does not contact the control column 43. The second slide rail 442 has a first position and a second position. When the guide wheel 12 is in the first position, there is a gap between the control push block 42 and the drive unit 432, that is, the two are still not in contact. When the guide wheel 12 is in the second position, the drive unit 432 abuts against the control push block 42 and pushes it, causing the control push block 42 to reach the position furthest from the axis of the control column 43. At this time, the adjustment block 3 is also pushed down, the wheel surface of the motor wheel 32 contacts the ground, and the main body long seat 1 is lifted up, thereby realizing the state adjustment of the adjustment block 3. That is, when the guide wheel 12 is in the first position, the main body long seat 1 is stably placed on the ground. When the guide wheel 12 is in the second position, the main body long seat 1 is suspended and the motor wheel 32 is in direct contact with the ground. Since the first position and the second position are both located in the second slide rail 442, the control column 43 cannot be directly removed from the main body long seat 1 in either state.

[0033] like Figure 2 and 3 As shown, the control column 43 is rotated manually. To simplify operation, a lever through-hole 433 is provided on the cylindrical part 431 of the control column 43. The length direction of the lever through-hole 433 is radial to the control column 43, and the lever through-hole 433 extends through both opposite sides of the control column 43. After inserting a pry bar-like tool into the lever through-hole 433, the upper part of the control column 43 forms a lever capable of transmitting torque. The operator can apply a pushing force to the pry bar to drive the control column 43 to rotate.

[0034] like Figure 1 As shown, the control column 43 and its lever through-hole 433 are also responsible for the installation of the guardrail long plate 2. The guardrail long plate 2 has two rows arranged side by side and located on opposite sides of the control column 43. When the length direction of the lever through-hole 433 is perpendicular to the length direction of the main body long seat 1, the guide wheel 12 is in the first position. The two rows of guardrail long plates 2 are fixed by threaded tie rods 21, and the lever through-hole 433 allows the tie rods 21 to pass through.

[0035] like Figure 1 and 3 As shown in this embodiment, there are two control columns 43 on a single main body long seat 1, and two corresponding adjustment blocks 3; each main body long seat 1 has two guardrail long plates 2 above it. The length of a single guardrail long plate 2 is greater than the distance between two adjacent control columns 43. There are also two tie rods 21 between every two parallel guardrail long plates 2. Thus, when a guardrail long plate 2 on a main body long seat 1 is installed and fixed, the angle of the two control columns 43 is fixed by the tie rods 21 and cannot be rotated, thereby keeping the control column 43 and the main body long seat 1 and guardrail long plate 2 connected to it relatively fixed.

[0036] like Figure 2 As shown, to improve the directional versatility when moving the main body seat 1, in one specific embodiment, a relay block 31 is rotatably connected to the bottom of the adjusting block 3, with the rotation axis being vertical. A motorized wheel 32 is rotatably connected to the relay block 31, thus forming a universal wheel mechanism with the adjusting block 3, the relay block 31, and the motorized wheel 32. In this embodiment, the number of motorized wheels 32 on a single relay block 31 is two, and the two motorized wheels 32 are coaxial, meaning that the number of motorized wheels 32 on one main body seat 1 is four.

[0037] like Figure 1 As shown, the adjacent main body long seats 1 do not directly contact each other. A rubber pad 13 is fixedly attached to the end face of the main body long seat 1 to reduce collision damage that occurs during the adjustment of the position of the main body long seat 1.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
