Description

Technical Field

[0001] The present invention relates to the technical field of bridge deck guardrails, and in particular to a bridge deck guardrail that is easy to disassemble and conveniently adjusted according to vehicle width. Background Art

[0002] As the name suggests, bridge guardrails are guardrails on the bridge deck used to separate roads. Since the driving size of the bridge deck is fixed, bridge guardrails are usually used to separate lanes. For cars of different sizes, different driving sizes are required. Usually, the placement of the bridge guardrails is adjusted to change the size of the driving road on the bridge deck. Although there are a variety of bridge guardrails on the market, some bridge guardrails still have certain problems in actual use.

[0003] Most of the guardrails currently used on bridge decks are fixed on the bridge deck with bolts. In this way, the size of the driving road on the bridge deck is fixed. If the size of the driving road needs to be adjusted, the guardrails on the bridge deck need to be dismantled. Moreover, some guardrails are very difficult to dismantle after being fixed, which makes the use of bridge guardrails extremely inconvenient. If movable bridge guardrails are used, the stability of the guardrail during use cannot be guaranteed, which may easily cause the guardrail to fall over in subsequent use.

[0004] Therefore, we propose a bridge guardrail that is easy to disassemble and adjust according to the width of the vehicle, so as to solve the above problems. Summary of the Invention

The other end of the fourth connecting rod is connected to the movable wheel frame, and the upper end of the movable wheel frame is installed on the inner side of the base, and the lower end of the movable wheel frame is installed with a movable wheel;

[0009] A limit block is fixed at the lower end of the movable button, and the limit block is symmetrically arranged at the lower end of the movable button. The movable button is rotatably connected to the third connecting rod, and the third connecting rod moves up and down and penetrates the base. A locking groove is provided at the place where the third connecting rod penetrates the base, and the size of the locking groove matches the limit block at the lower end of the movable button;

[0010] The upper end of the movable wheel frame is rotatably connected to the base. When the movable wheel frame rotates to the lowest position on the base, the movable wheels on the movable wheel frame protrude from the bottom surface of the base. When the movable wheel frame rotates to the highest position on the base, the movable wheel frame and the movable wheels are both hidden in the base.

[0011] Both ends of the fourth connecting rod are movably connected to the movable wheel frame and the third connecting rod.

[0012] Preferably, positioning teeth are evenly distributed on the bottom surface of the base, and the positioning teeth are conical in shape, and the height of the positioning teeth is 5 mm, and the base is made of cast iron.

[0013] Compared with the prior art, the present invention has the following beneficial effects: the bridge deck guardrail is easy to disassemble and can be conveniently adjusted according to the width of the vehicle;

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-7 The present invention provides a technical solution: a bridge guardrail that is easy to disassemble and conveniently adjusted according to the width of a vehicle, including a base 1, a support column 2, a first connecting rod 3, a movable column 4, a first connecting member 5, a second connecting member 6, a sleeve cross bar 7, a second connecting rod 8, a fixed cross bar 9, a positioning bolt 10, a movable button 11, a moving wheel frame 12, a moving wheel 13, a limit block 14, a third connecting rod 15, a locking slot 16, a fourth connecting rod 17 and a positioning tooth 18. The support column 2 is fixed above the base 1, and the first connecting rod 3 is fixed at the upper end of the support column 2. A movable column 4 is sleeved on the first connecting rod 3, and a first connecting piece 5 is fixed to the outer side of the movable column 4 and the supporting column 2. The outer side of the first connecting piece 5 is connected to the second connecting piece 6, and the outer side of the second connecting piece 6 is connected to the sleeve cross bar 7 and the fixed cross bar 9. The outer end of the fixed cross bar 9 is fixed with a second connecting rod 8, and the outer side of the second connecting rod 8 is sleeved with the sleeve cross bar 7. Through the sleeve connection between the above structures, the overall size of the bridge guardrail can be conveniently adjusted, and the bridge guardrail can also be quickly disassembled and assembled, thereby improving the utilization efficiency of the bridge guardrail.

[0027] The supporting column 2 and the first connecting rod 3, as well as the second connecting rod 8 and the fixed cross bar 9 are all integrated structures, and the movable column 4 and the first connecting rod 3, as well as the sleeve cross bar 7 and the second connecting rod 8 are all movably sleeved. The outer side of the movable column 4 is threadedly connected with a positioning bolt 10, and the positioning bolt 10 passes through the movable column 4 and is squeezed and connected with the first connecting rod 3, so that the height between the supporting column 2 and the movable column 4 can be adjusted up and down, and the length between the sleeve cross bar 7 and the fixed cross bar 9 can be adjusted left and right. In this way, the size of the bridge guardrail when in use can be adjusted, thereby improving the use value of the bridge guardrail.

[0028] Two groups of moving mechanisms are symmetrically provided on the base 1, and the moving mechanisms include a movable button 11, a movable wheel frame 12, a movable wheel 13, a third connecting rod 15 and a fourth connecting rod 17. The lower end of the movable button 11 is connected to the third connecting rod 15, and the lower end of the third connecting rod 15 is connected to the fourth connecting rod 17. The other end of the fourth connecting rod 17 is connected to the movable wheel frame 12, and the upper end of the movable wheel frame 12 is installed on the inner side of the base 1, and the lower end of the movable wheel frame 12 is installed with a movable wheel 13. The bridge guardrail can be conveniently moved through the two groups of moving mechanisms, so that the position of the bridge guardrail on the bridge deck can be quickly adjusted, so that the road on the bridge deck can be quickly adapted to vehicles of different sizes.

[0029] A limit block 14 is fixed to the lower end of the movable button 11, and the limit block 14 is symmetrically arranged at the lower end of the movable button 11. The movable button 11 and the third connecting rod 15 are rotatably connected, and the third connecting rod 15 moves up and down to pass through the base 1. A locking groove 16 is provided at the place where the third connecting rod 15 passes through the base 1, and the size of the locking groove 16 is consistent with the limit block 14 at the lower end of the movable button 11. By pressing the movable button 11, the working state of the movable mechanism can be adjusted. At the same time, the setting of the limit block 14 can ensure the stability of the working state of the movable mechanism.

[0030] The upper end of the moving wheel frame 12 is rotatably connected to the base 1. When the moving wheel frame 12 rotates to the lowest position on the base 1, the moving wheels 13 on the moving wheel frame 12 protrude from the bottom surface of the base 1. When the moving wheel frame 12 rotates to the highest position on the base 1, the moving wheel frame 12 and the moving wheels 13 are both hidden in the base 1. When the moving wheel frame 12 rotates to the lowest position, the moving wheels 13 contact the bottom surface to support the base 1, so that the base 1 can be moved directly. When the moving wheel frame 12 rotates to the highest position, the base 1 directly contacts the bottom surface, which ensures that the base 1 is in a stable state. At the same time, the moving wheel frame 12 and the moving wheels 13 will not adversely affect the stable placement of the base 1.

[0031] Both ends of the fourth connecting rod 17 are movably connected to the movable wheel frame 12 and the third connecting rod 15, thereby ensuring normal adjustment of the movable wheel frame 12.

[0032] Positioning teeth 18 are evenly arranged on the bottom surface of the base 1, and the shape of the positioning teeth 18 is conical, and the height of the positioning teeth 18 is 5 mm. The base 1 is made of cast iron material, which further enhances the stability of the base 1 in the placement state and effectively prevents the base 1 from sliding through the positioning teeth 18.

[0033] The working principle of this embodiment is as follows: first, the assembly of the bridge guardrail needs to be completed. First, the base 1 is placed in the working position. Then, the movable column 4 is sleeved on the first connecting rod 3 of the supporting column 2, and the position of the movable column 4 on the first connecting rod 3 is fixed with the positioning bolt 10. Then, the second connecting piece 6 is connected to the first connecting piece 5 through a pin shaft, and the second connecting piece 6 can be rotated up and down on the first connecting piece 5. Then, the sleeve cross bar 7 and the fixed cross bar 9 are respectively connected to the second connecting piece 6 through a pin shaft. The sleeve cross bar 7 and the fixed cross bar 9 can be rotated left and right on the second connecting piece 6. Finally, the sleeve cross bar 7 and the fixed cross bar 9 in the corresponding horizontal position are connected by the second connecting rod 8. The above completes the arrangement of the bridge guardrail.

[0034] After the bridge guardrail is arranged, the road on the bridge can be separated. At the same time, due to the presence of the positioning teeth 18 at the bottom of the base 1 and the weight of the base 1 itself, the bridge guardrail can be effectively prevented from moving, and the stability of the working state of the bridge guardrail can be ensured. If the road width needs to be adjusted according to the width of the vehicle in the future, the bridge guardrail can be directly moved;

[0035] When the bridge guardrail is moved, by pushing the movable column 4 to tilt slightly to one side, the side of the base 1 with the movable mechanism can be lifted up, and the movable button 11 is pressed. The limit block 14 on the movable button 11 will pass through the positioning slot 16 on the base 1, and then the fourth connecting rod 17 is pressed down by the third connecting rod 15. The fourth connecting rod 17 will push the movable wheel frame 12 to rotate downward, and the movable wheel 13 on the movable wheel frame 12 will support the ground. At the same time, the movable button 11 is rotated, and the limit block 14 on the movable button 11 will be misaligned with the positioning slot 16 on the base 1, so that the third connecting rod 15 can be fixed to stabilize the positions of the movable wheel frame 12 and the movable wheel 13.

[0036] When the moving mechanism on one side of the base 1 is unfolded, the moving mechanism on the other side is unfolded in the above manner, so that the entire bridge guardrail can be supported by the moving wheel 13, and then the base 1 can be directly pushed to move. At the same time, when the base 1 moves, the length size can be changed accordingly due to the socket connection between the socket cross bar 7, the second connecting rod 8, and the fixed cross bar 9. Moreover, after being connected by the first connecting member 5 and the second connecting member 6, the base 1 can be moved up and down and left and right, so that the base 1 at a single position will not be affected by the left and right bases 1 when moving, and the position movement of the base 1 at a single position can be completed quickly. According to the above manner, the position movement of the base 1 can be completed sequentially.

[0037] When the position of the base 1 is moved, the movable button 11 can be rotated to make the limit block 14 move upward through the locking slot 16. The third connecting rod 15 pulls the movable wheel frame 12 to rotate upward through the fourth connecting rod 17, thereby hiding the movable wheel 13 in the base 1. The lower surface of the base 1 contacts the ground. The positioning teeth 18 ensure the stability of the placement state, so that the size of the road separated by the bridge guardrail can be changed to accommodate vehicles of different widths crossing the bridge.

[0038] If the bridge guardrail needs to be disassembled later, the first connecting member 5 and the second connecting member 6 can be directly disassembled to remove the sleeve cross bar 7 and the fixed cross bar 9, and then the support column 2 and the movable column 4 can be separated by the positioning bolt 10 to complete the quick disassembly of the bridge guardrail.

[0039] The above completes the use process of the bridge deck guardrail, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
