Description

Technical Field

[0001] This application relates to the field of guardrails, and in particular to a heightening device for corrugated beam guardrails. Background Art

[0002] A corrugated beam guardrail is composed of two corrugated steel guardrail plates and two columns, which are fixed on both sides of the road or in the central isolation belt through the columns to form a continuous protection barrier; during the major overhaul of the road surface, in order to ensure that the road meets the rapidly increasing traffic volume, the road surface structure is overlaid and reconstructed. After the road surface is overlaid, the elevation of the road surface will increase, resulting in the setting height of the original corrugated beam guardrail on the road not meeting the specification requirements, and heightening treatment is required.

[0003] In traditional methods, generally, all the existing corrugated beam guardrails are removed, and then the guardrail columns are moved forward one or two meters along the original column positions and re-piled to install the guardrails, which prolongs the processing cycle of the corrugated beam guardrails, thereby increasing the processing cost of the corrugated beam guardrails. Utility Model Content

[0004] In order to improve the problem of the processing cycle of corrugated beam guardrails, this application provides a heightening device for corrugated beam guardrails.

[0005] A heightening device for corrugated beam guardrails provided by this application adopts the following technical solutions:

[0006] A heightening device for corrugated beam guardrails includes a column, an adjusting rod, a barrier block, and a corrugated beam plate. One end of the column is for ground installation, and the other end of the column is provided with a sliding cavity for the adjusting rod to slide. One end of the barrier block is connected to the end face of the adjusting rod protruding from the column, and the other end of the barrier block is connected to the plate surface of the corrugated beam plate.

[0007] By adopting the above technical solutions, one end of the column is installed on the ground to form a support. One end of the barrier block is connected to the end face of the adjusting rod protruding from the column, and the other end of the barrier block is installed on the plate surface of the corrugated beam plate. When the elevation of the road surface increases, the adjusting rod is driven to slide along the inner wall of the sliding cavity, realizing an equal-gradient increase in the height of the corrugated beam guardrail, without having to remove all the existing corrugated beam guardrails and reinstall them, shortening the processing cycle of the corrugated beam guardrails, thereby reducing the processing cost of the corrugated beam guardrails.

[0008] Optionally, a positioning assembly is connected between the adjusting rod and the column. The positioning assembly includes a positioning bolt. The column surface is provided with a positioning hole for the positioning bolt to pass through. The positioning hole communicates with the sliding cavity, and the end of the positioning bolt can pass through the positioning hole and abut against the surface of the adjusting rod to form positioning.

[0009] By adopting the above technical solution, when the adjusting rod slides to an appropriate height on the inner wall of the sliding cavity, the positioning bolt passes through the positioning hole and abuts against the surface of the adjusting rod to form a positioning, so that the adjusting rod is not easily offset in the sliding cavity, thereby ensuring the limiting stability of the adjusting rod in the sliding cavity.

[0010] Optionally, a plurality of threaded holes are spaced apart on the surface of the adjusting rod facing the positioning hole, the arrangement direction of the threaded holes is parallel to the sliding direction of the adjusting rod, and the end of the positioning bolt is screwed tightly into the threaded hole.

[0011] By adopting the above technical solution, when the adjusting rod slides to an appropriate height on the inner wall of the sliding cavity, the positioning hole communicates with one of the threaded holes, the end of the positioning bolt passes through the positioning hole and is screwed and fixed on the inner wall of the threaded hole, so that the adjusting rod is not easily offset in the sliding cavity, and further improves the limiting stability of the adjusting rod in the sliding cavity.

[0012] Optionally, the positioning assembly further includes a plurality of positioning plates and a plurality of first elastic members. A plurality of positioning grooves for the positioning plates to slide are spaced apart on the surface of the adjusting rod facing the positioning hole. The positioning grooves are located between adjacent positioning cavities. The first elastic members correspond to the positioning plates one by one. When one end of the first elastic member in the direction of the elastic force is connected to the inner wall of the positioning groove and the other end of the first elastic member in the direction of the elastic force is connected to the plate surface of the positioning plate, the first elastic member has an elastic force to drive the positioning plate to slide away from the positioning groove, and there is a tendency for the plate surface of the positioning plate to protrude from the rod surface of the adjusting rod. When the plate surface of the positioning plate protruding from the adjusting rod abuts against the top surface of the column, the positioning hole communicates with one of the threaded holes.

[0013] By adopting the above technical solution, when the adjusting rod slides to an appropriate position on the inner wall of the sliding cavity, the limiting effect of the inner wall of the sliding cavity on the positioning plate disappears, the elastic force of the first elastic member drives the positioning plate to slide away from the positioning groove, and the plate surface of the positioning plate close to the column abuts against the top surface of the column, so that the adjusting rod is not easily slid on the inner wall of the sliding cavity, realizing the preliminary limitation of the adjusting rod in the sliding cavity. At the same time, the positioning hole communicates with one of the threaded holes, and the end of the positioning bolt passes through the positioning hole and is screwed and fixed on the inner wall of the threaded hole to form a fixation, so that the adjusting rod is not easily offset in the sliding cavity, thereby improving the limiting stability of the adjusting rod on the inner wall of the sliding cavity.

[0014] Optionally, a guiding surface is provided on the end surface of the positioning plate protruding from the adjusting rod, the guiding surface is in a circular arc convex shape, and the guiding surface can abut against the inner wall of the sliding cavity and guide the positioning plate to slide away from the positioning groove.

[0015] By adopting the above technical solution, when the adjusting rod slides along the inner wall of the sliding cavity away from the column, the guiding surface abuts against the inner wall of the sliding cavity. When the closing effect of the inner wall of the sliding cavity on the positioning groove disappears, the guiding surface abuts against the inner wall of the sliding cavity and guides the positioning plate to slide away from the positioning groove. The protruding surface of the positioning plate presses against the top surface of the column, realizing the preliminary limit of the adjusting rod on the column.

[0016] Optionally, a limiting ring bladder is connected to the surface of the column, and the inner ring of the limiting ring bladder abuts against the outer peripheral surface of the positioning bolt to form a limit.

[0017] By adopting the above technical solution, when the end of the positioning bolt is screwed and fixed in the threaded hole, the inner ring wall of the limiting ring bladder abuts against the outer peripheral surface of the positioning bolt to form a limit, making it difficult for the positioning bolt to rotate in the threaded hole, thereby improving the connection stability of the positioning bolt on the column.

[0018] Optionally, an inflation assembly is connected to the column. The inflation assembly includes an inflation piston. An inflation cavity for the inflation piston to slide is formed on the surface of the column. The sliding direction of the inflation piston is parallel to the sliding direction of the positioning bolt. The end face of the inflation piston protruding from the column can abut against the surface of the positioning bolt, and the inflation cavity communicates with the inner cavity of the limiting ring bladder.

[0019] By adopting the above technical solution, when the end of the positioning bolt passes through the positioning hole and is screwed and fixed on the inner wall of the threaded hole, the surface of the positioning bolt abuts against the surface of the inflation piston and drives the inflation piston to slide on the inner wall of the inflation cavity. The air pressure in the inflation cavity increases. The inflation cavity communicates with the inner cavity of the limiting ring bladder, and the air in the inflation cavity enters the inner cavity of the limiting ring bladder. The inner peripheral surface of the limiting ring bladder is pressurized and expanded to abut against the outer peripheral surface of the positioning bolt to form a fixation, further improving the connection stability of the positioning bolt on the column.

[0020] Optionally, the inflation assembly further includes an elastic member II. One end of the elastic member II in the direction of the elastic force is connected to the inner wall of the inflation cavity, and the other end of the elastic member II in the direction of the elastic force is connected to the surface of the inflation piston. The elastic member II has an elastic force to drive the inflation piston to slide away from the inflation cavity, and the end of the inflation piston has a tendency to protrude from the surface of the column.

[0021] By adopting the above technical solution, when the positioning bolt is unscrewed from the positioning hole, the pressure of the positioning bolt on the inflation piston disappears, and the elastic force of the elastic member II drives the inflation piston to slide away from the inflation cavity. The end of the inflation piston protrudes from the surface of the column, eliminating the need to manually adjust the position of the inflation piston on the inner wall of the inflation cavity and realizing the automatic reset of the inflation piston.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1.

Detailed Description of the Invention

[0029] The following is a further detailed description of the present application in conjunction with the attached Figure 1-2 drawings.

[0030] The embodiment of the present application discloses a heightening device for a corrugated beam guardrail. Referring to Figure 1 and Figure 2 , a heightening device for a corrugated beam guardrail includes a column 1, an adjusting rod 2, an anti-blocking head 3 and a corrugated beam plate 4. The bottom of the column 1 is fixed on the road surface by cement pouring. A sliding cavity 11 for the adjusting rod 2 to slide is provided on the top surface of the column 1. The sliding direction of the adjusting rod 2 is parallel to the height direction of the column 1. One end of the anti-blocking head 3 is provided with a connecting hole 31 for the end of the adjusting rod 2 to pass through. The axis of the connecting hole 31 is parallel to the height direction of the adjusting rod 2. The connecting hole 31 penetrates through the outer wall of the anti-blocking head 3 along its own axis. The inner wall of the connecting hole 31 abuts against the outer wall of the circumference of the adjusting rod 2 to form a limit. At the same time, the end of the bolt passes through the outer wall of the anti-blocking head 3 and is threadedly tightened and fixed on the outer wall of the adjusting rod 2 to realize the fixation between the adjusting rod 2 and the anti-blocking head 3.

[0031] Refer to Figure 2 , the corrugated beam plate 4 is fixed on the surface of the anti-collision head 3 away from the adjusting rod 2 by bolts. When it is necessary to adjust the height of the corrugated beam guardrail, the adjusting rod 2 is driven to slide on the inner wall of the sliding cavity 11, so as to realize arbitrary adjustment of the height of the corrugated beam guardrail, without having to completely remove the existing corrugated beam guardrail and reinstall it, shortening the processing cycle of the corrugated beam guardrail, and thus reducing the processing cost of the corrugated beam guardrail.

[0032] Refer to Figure 2 , a positioning assembly 5 is connected between the adjusting rod 2 and the column 1. The positioning assembly 5 can limit the adjusting rod 2 in the adjusting cavity; the positioning assembly 5 includes a positioning bolt 51, a plurality of positioning plates 52 and a plurality of first elastic members 53. A positioning hole 12 for the end portion of the positioning bolt 51 to pass through is formed on the surface of the column 1. The axis of the positioning hole 12 is perpendicular to the height direction of the column 1. The positioning hole 12 penetrates through the outer wall of the column 1 along its own axis and communicates with the sliding cavity 11. A plurality of threaded holes 21 are spaced apart on the surface of the adjusting rod 2 facing the positioning hole 12. The axis of the threaded hole 21 is parallel to the axis of the positioning hole 12, and the arrangement direction of the positioning holes 12 is parallel to the height direction of the adjusting rod 2. The end portion of the positioning bolt 51 can pass through the positioning hole 12 and be screwed and fixed on the inner wall of one of the threaded holes 21.

[0033] Refer to Figure 2 , a plurality of positioning grooves 22 for the positioning plates 52 to slide are spaced apart on the surface of the adjusting rod 2 facing the positioning hole 12. The positioning grooves 22 are located between adjacent threaded holes 21. The sliding direction of the positioning plates 52 is parallel to the axis of the threaded holes 21. The first elastic member 53 can be a compression spring or a tension spring. In the embodiment of the present application, the first elastic member 53 is a compression spring and has a certain deformation ability. The first elastic members 53 and the positioning plates 52 are in one-to-one correspondence. One end of the elastic force direction of the first elastic member 53 is fixed on the inner wall of the positioning groove 22, and the other end of the elastic force direction of the first elastic member 53 is fixed on the plate surface of the positioning plate 52. The first elastic member 53 has an elastic force to drive the positioning plate 52 to slide away from the positioning groove 22, and the end portion of the positioning plate 52 protrudes from the rod surface of the adjusting rod 2.

[0034] Refer to Figure 2 , a guiding surface 521 is provided on the end surface of the positioning plate 52 away from the first elastic member 53. The guiding surface 521 is in a circular arc convex shape. The guiding surface 521 can abut against the inner wall of the sliding cavity 11 and guide the positioning plate 52 to slide away from the positioning groove 22, reducing the wear between the positioning plate 52 and the inner wall of the sliding cavity 11, and thus prolonging the service life of the corrugated beam guardrail.

[0035] Refer to Figure 2, when the adjusting rod 2 slides to an appropriate height on the inner wall of the sliding cavity 11, the closing effect of the inner wall of the sliding cavity 11 on the positioning groove 22 disappears. The elastic force of the first elastic member 53 drives the positioning plate 52 to slide away from the positioning groove 22. The guiding surface 521 abuts against the inner wall of the sliding cavity 11 and guides the positioning plate 52 to slide away from the positioning groove 22. The plate surface of the positioning plate 52 protruding from the adjusting rod 2 abuts against the top surface of the column 1, realizing the preliminary positioning of the adjusting rod 2 in the sliding cavity 11. At the same time, the positioning hole 12 communicates with one of the threaded holes 21, and the end of the positioning bolt 51 passes through the positioning hole 12 and is threadedly tightened and fixed on the inner wall of the threaded hole 21, so that the adjusting rod 2 is not easily deflected on the inner wall of the sliding cavity 11, thereby improving the limiting stability of the adjusting rod 2 on the inner wall of the sliding cavity 11.

[0036] Refer to Figure 2 , a limiting ring bladder 6 is fixed on the surface of the column 1. The material of the limiting ring bladder 6 can be rubber or silica gel. In the embodiment of the present application, the material of the limiting ring bladder 6 is rubber, which has a certain deformation ability. The inner ring of the limiting ring bladder 6 surrounds the positioning hole 12, and the inner peripheral surface of the limiting ring bladder 6 can abut against the outer peripheral surface of the positioning bolt 51 to form a fixation, so that the positioning bolt 51 is not easily deflected in the threaded hole 21, thereby improving the limiting stability of the positioning bolt 51 on the column 1.

[0037] Refer to Figure 2 , an inflation assembly 7 is installed on the column 1, and the inflation assembly 7 can inflate the inner cavity of the limiting ring bladder 6; the inflation assembly 7 includes an inflation piston 71 and a second elastic member 72. The material of the inflation piston 71 can be rubber or silica gel. In the embodiment of the present application, the material of the inflation piston 71 is rubber, which has a certain deformation ability. An inflation cavity 13 for the inflation piston 71 to slide is formed on the surface of the column 1, and the sliding direction of the inflation piston 71 is parallel to the axis of the positioning hole 12; the second elastic member 72 can be a compression spring or a tension spring. In the embodiment of the present application, the second elastic member 72 is a compression spring, which has a certain deformation ability. One end in the direction of the elastic force of the second elastic member 72 is fixed on the inner wall of the inflation cavity 13, and the other end in the direction of the elastic force of the second elastic member 72 is fixed on the surface of the inflation piston 71. The second elastic member 72 has an elastic force to drive the inflation piston 71 to slide away from the inflation cavity 13, and there is a tendency for the end of the inflation piston 71 to protrude from the outer wall of the adjusting rod 2.

[0038] Refer to Figure 2 , the inflation cavity 13 communicates with the inner cavity of the limiting ring bladder 6. When the end of the positioning bolt 51 passes through the positioning hole 12 and is threadedly tightened and fixed on the inner wall of the threaded hole 21, the surface of the positioning bolt 51 abuts against the surface of the inflation piston 71 and drives the inflation piston 71 to slide towards the inflation cavity 13. The air pressure in the inflation cavity 13 increases, and the air in the inflation cavity 13 enters the inner cavity of the limiting ring bladder 6. The inner ring of the limiting ring bladder 6 is pressurized and expanded to abut against the outer peripheral surface of the positioning bolt 51 to form a limit, so that the positioning bolt 51 is not easily deflected in the threaded hole 21, thereby improving the limiting stability of the positioning bolt 51 in the threaded hole 21.

[0039] The implementation principle of a heightening device for a corrugated beam guardrail in an embodiment of the present application is as follows: The adjusting rod 2 slides to a suitable height on the inner wall of the sliding cavity 11, and the closing effect of the inner wall of the sliding cavity 11 on the positioning groove 22 disappears. The elastic force of the first elastic member 53 drives the positioning plate 52 to slide away from the positioning groove 22. The guiding surface 521 abuts against the inner wall of the sliding cavity 11 and guides the positioning plate 52 to slide away from the positioning groove 22. The plate surface of the positioning plate 52 protruding from the adjusting rod 2 abuts against the top surface of the column 1, realizing the preliminary positioning of the adjusting rod 2 in the sliding cavity 11. The end of the positioning bolt 51 passes through the positioning hole 12 and is screwed and fixed on the inner wall of the threaded hole 21, making it difficult for the adjusting rod 2 to shift on the inner wall of the sliding cavity 11, thereby improving the limit stability of the adjusting rod 2 on the inner wall of the sliding cavity 11, realizing arbitrary adjustment of the height of the corrugated beam guardrail, without having to completely remove the existing corrugated beam guardrail and reinstall it, shortening the processing cycle of the corrugated beam guardrail, and thus reducing the processing cost of the corrugated beam guardrail.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby.
