Description

Technical Field

[0001] The invention belongs to the technical field of road construction equipment, and in particular relates to a traction device for installing a corrugated plate for road construction. Background Art

[0002] High-speed corrugated guardrail, also known as corrugated beam guardrail, is a major form of semi-rigid guardrail. It is mainly composed of corrugated steel guardrail panels spliced ​​together and supported by columns to form a continuous structure. This type of guardrail uses the deformation of the soil foundation, columns, and beams to absorb collision energy, forcing the out-of-control vehicle to change direction and return to the normal driving route to prevent the vehicle from running off the road, thereby protecting the safety of vehicles and passengers and reducing losses caused by accidents. There are straight roads and curves on the highway. When installing corrugated guardrails on straight roads, you only need to directly install the two ends of the corrugated guardrail on the columns. When installing corrugated guardrails on curves, you need to first install one end of the corrugated guardrail on the column, and then manually push the corrugated guardrail to make it arc-shaped until the other end of the corrugated guardrail abuts against the column on the other side, and then connect it with bolts.

[0003] However, it takes a long time to install corrugated guardrails on curves by manual means. In order to improve the installation efficiency, a road construction corrugated plate installation traction device of Chinese patent CN118932903A includes an installation column, a corrugated plate, a traction frame, a structural reinforcement plate, a cable guide bracket, and a cable storage roller. The traction frame and the limit frame are assembled and installed and then hung on the corrugated plate body. The hanging sleeve positioning sleeve is mounted on the installation column. The cable guide bracket is vertically installed at the side end surface of the structural reinforcement plate. The traction frame is synchronously linked with the cable and the cable storage roller. A road construction corrugated plate installation traction device, the limit frame is hung on the outer side of the corrugated plate, the hole position docking rod of the operating limit frame is docked with the corrugated plate installation hole, the horizontal docking bolt is screwed and the docking threaded sleeve of the limit frame is threadedly docked and assembled and fixed, the traction frame is positioned with the corrugated plate, the cable storage roller is rotated, and the traction cable is stably pulled by the traction rope guide roller of the cable guide bracket to pull the limit frame to drive the corrugated plate to achieve fixed installation after arc bending. The device can achieve safe, stable and efficient.

[0004] However, in the prior art, after one end of the corrugated guardrail is fixed, the other end is assisted in being fixed by a traction device, and the corrugated guardrail is only pulled until it abuts against the column. Therefore, it is difficult to control the curvature of the corrugated guardrail that needs to be bent. When the corrugated guardrail is pulled to the connection point of the column, it is difficult to ensure that the connection point of the corrugated guardrail coincides with the connection point of the column. Therefore, after the corrugated guardrail is pulled by the traction device, it is necessary to fine-tune the position of the corrugated guardrail, and then manually connect the corrugated guardrail and the column with bolts, which not only wastes a lot of labor, but also has low installation efficiency. Based on this, a traction device for installing corrugated plates in road construction is proposed. Summary of the invention

[0005] In order to solve the problem in the prior art that it is difficult to ensure that the connection points of the corrugated guardrail and the connection points of the columns coincide with each other, and the position of the corrugated guardrail needs to be fine-tuned, the present invention provides a traction device for installing a corrugated plate in road construction.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A road construction corrugated plate installation and traction device of the present invention comprises a fixed component and a movable component, wherein the fixed component is slidably installed on a column, and the movable component is detachably connected to the corrugated plate, the fixed component comprises a fixed plate and a traction mechanism, a side surface of the fixed plate is provided with a guide opening facing one side of the movable component, and the inner walls on both sides of the guide opening are inclined surfaces, a traction chain on the traction mechanism passes through the fixed plate and is connected to the movable component, and the traction chain pulls the movable component to slide along the inclined surface of the guide opening to the installation area of ​​the fixed plate for pulling the corrugated plate to dock with the column for installation.

[0008] Furthermore, the movable assembly includes a movable plate and two rollers, and the two rollers are rotatably connected to two vertical side edges of the movable plate facing the fixed assembly.

[0009] Furthermore, a twisting mechanism is provided in the fixed plate, the twisting mechanism is transmission-connected with the traction chain, a nut is placed on the twisting mechanism, a bolt is placed on the movable plate, and the twisting mechanism drives the nut to rotate for connection with the bolt.

[0010] Furthermore, the twisting mechanism includes a first gear, a first screw and a turntable, a traction channel is opened on the fixed plate for passing the traction chain, the first gear is coaxially connected to the first screw, the first screw is rotatably connected to the fixed plate and meshingly connected to the turntable, a first mounting groove is provided on the turntable and leads to the outside of the fixed plate for placing a nut, the rim surface of the first gear is tangent to the traction channel and is transmission-connected to the traction chain.

[0011] Furthermore, the twisting mechanism also includes a second gear and a second screw rod, the second gear is coaxially connected to the second screw rod, the second screw rod is arranged parallel to the first screw rod and meshed with the other side of the turntable, and the first gear and the second gear mesh with each other.

[0012] Furthermore, the movable plate is provided with a transverse groove for limiting the position of the corrugated plate, and the transverse groove is provided with a second installation groove corresponding to the position of the first installation groove for placing bolts.

[0013] Furthermore, the guide opening of the fixing plate includes a section with a constant cross section and a section with a variable cross section, inner walls on both sides of the section with a variable cross section are inclined surfaces, and inner walls on both sides of the section with a constant cross section are vertical surfaces.

[0014] Furthermore, two groups of twisting mechanisms are symmetrically arranged on both sides of the traction channel, and two groups of second installation grooves are correspondingly arranged on the movable plate.

[0015] Furthermore, the traction mechanism also includes a reel, which is arranged in the fixed plate and connected to the traction chain for recovering and releasing the traction chain.

[0016] Furthermore, a pulley is provided on the movable plate, one end of the traction chain is connected to the front end of the fixed plate, and the other end of the traction chain is passed through the pulley and penetrates the traction channel to be connected to the reel.

[0017] The beneficial effects of the present invention are:

[0018] (1) The movable plate is gradually pulled closer to the fixed plate by a traction mechanism. By setting a guide opening on the fixed plate, after the movable plate is pulled closer to the inner side wall of the guide opening of the fixed plate, it will move toward the guide opening as it is gradually pulled closer. The corrugated plate will gradually be subjected to pressure and bend and deform. When it moves to the minimum width of the guide opening, the movable plate is completely in the predetermined position. At this time, the movable plate is completely docked with the fixed plate, and the connection point of the corrugated plate is completely overlapped with the connection point of the column, completing the installation of the corrugated plate and the column. By setting a guide opening on the fixed plate, the movable plate can be quickly guided to move to a position, and a quick installation can be achieved.

[0019] (2) The traction chain passes through the traction channel, and the teeth on the first gear mesh with the traction chain. The action of the traction chain pulling the movable plate will synchronously drive the rotation of the first gear. When the first gear rotates, the first screw rod also rotates. The rotation of the first screw rod drives the turntable to rotate. The first mounting groove on the side of the turntable can be used to place a nut. The turntable is provided with an opening on the side of the fixed plate facing the movable plate for connection with a bolt. The pulling of the traction chain will drive the bolt to approach the nut and can be tightened synchronously with the bolt. The work of installing the corrugated plate on the column can be completed by only one worker, which greatly improves the work efficiency.

[0020] (3) The guide opening at the variable section section is an enlarged and inclined shape toward one side of the movable plate. When the movable plate moves to the variable section section, it is used to correct the position of the movable plate. The side walls of the guide opening of the equal section section are parallel to each other. Therefore, when the movable plate moves to the equal section section, it means that the guide opening variable section section has completed the position correction of the movable plate. At this time, the connection point of the bolt coincides with the connection point on the column and also coincides with the nut. The movable plate continues to move at the equal section section, so that the bolt and the nut gradually approach and connect, completing the installation of the corrugated plate and the column.

DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, 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.

[0031] like Figure 1-Figure 7As shown; a traction device for installing a corrugated plate 4 for road construction of the present invention comprises a fixed component and a movable component, wherein the fixed component is slidably installed on the column 3, and the movable component is detachably connected to the corrugated plate 4, and the fixed component comprises a fixed plate 1 and a traction mechanism, and a guide opening 17 facing one side of the movable component is provided on the side of the fixed plate 1, and the inner walls on both sides of the guide opening 17 are inclined surfaces, and a traction chain on the traction mechanism passes through the fixed plate 1 and is connected to the movable component, and the traction chain pulls the movable component to slide along the inclined surface of the guide opening 17 to the installation area of ​​the fixed plate 1 for pulling the corrugated plate 4 to dock with the column 3 for installation;

[0032] Because in the prior art, after one end of the corrugated guardrail is fixed, when the other end is fixed with the assistance of the traction device, the corrugated guardrail is only pulled to abut against the column 3. However, during actual installation, at the bend position of some roads, the two columns 3 may not be completely in the same plane due to the setting position and the need to connect the two front and rear corrugated plates 4. In this case, the corrugated plates 4 need to be bent into a certain curvature, so it is difficult to control the curvature that the corrugated guardrail needs to be bent. When the corrugated guardrail is pulled to the connection point of the column 3, it is difficult to ensure that the connection point of the corrugated guardrail coincides with the connection point of the column 3. Therefore, after the corrugated guardrail is pulled by the traction device, the position of the corrugated guardrail needs to be fine-tuned, and then the corrugated guardrail and the column 3 are manually connected by bolts, which not only wastes a lot of labor but also has low installation efficiency.

[0033] In this embodiment, the fixed plate 1 needs to be placed or installed and connected to the predetermined position of the column 3, and the movable plate 2 needs to be connected to the predetermined position of the corrugated plate 4, so that one end of the traction chain is connected to the fixed plate 1 and the other end is connected to the movable plate 2, and then the movable plate 2 is gradually pulled close to the fixed plate 1 by the traction chain. In order to accurately connect the connection point on the corrugated plate 4 with the connection point on the column 3 after the movable plate 2 is close to the fixed plate 1, a guide opening 17 is provided on the fixed plate 1, and the guide opening 17 forms an expanded trumpet shape toward one side of the movable plate 2, and gradually shrinks from the outside to the inside. The minimum width of the guide opening 17 is consistent with the width of the movable plate 2, so when the movable plate 2 is pulled close to the inner side of the guide opening 17 of the fixed plate 1 After the wall abuts, it will move toward the guide opening 17 as it is gradually pulled closer. Then, when the corrugated plate 4 is fixed at one end and the other end gradually abuts against the column 3, the corrugated plate 4 will gradually be subjected to pressure and bend and deform. At this time, the movable plate 2 may abut against the inner wall of one side on the left or right in the guide opening 17. However, when it moves to the minimum width of the guide opening 17, the movable plate 2 is completely in the predetermined position. At this time, the movable plate 2 is completely abutted with the fixed plate 1, and the connection point of the corrugated plate 4 is completely coincident with the connection point of the column 3. The connection point of the corrugated plate 4 and the column 3 can be a bolt hole. After the connection points of the two coincide, bolts and nuts can be installed in the bolt holes to complete the installation of the corrugated plate 4 and the column 3. By setting the guide opening 17 on the fixed plate 1, the moving position of the movable plate 2 can be quickly guided, and rapid installation can be achieved. There is no need to manually fine-tune and align the connection points of the corrugated plate 4 and the column 3, which improves work efficiency and reduces manpower.

[0034] As the movable plate 2 pushes the corrugated plate 4 and enters the guide opening 17 of the fixed plate 1, the corrugated plate 4 will gradually bend and deform, and the corrugated plate 4 will gradually accumulate force after bending and deforming. At this time, the corrugated plate 4 will also push one side of the movable plate 2 to abut against the inner wall of the guide opening 17, making it difficult for the movable plate 2 to be pushed into the guide opening 17. In order to enable the movable plate 2 to be smoothly pushed into the guide opening 17 when subjected to force, in one embodiment, the movable assembly includes the movable plate 2 and two rollers 21, and the two rollers 21 are rotatably connected to the two vertical side edges of the movable plate 2 facing the fixed assembly.

[0035] That is, the two rollers 21 are respectively located on the side walls of the movable plate 2 that abut against the inner wall of the guide opening 17, and the rim surfaces of the two rollers 21 protrude from the side edges of the movable plate 2. When the movable plate 2 is pushed into the guide opening 17 and abuts against the inner wall of the guide opening 17, the two rollers 21 will gradually rotate as it is pushed in, making the pushing of the movable plate 2 smoother and reducing the traction force of the traction mechanism.

[0036] Since in the prior art, the corrugated plate 4 can only be pulled close to the column 3, and the bolts and nuts cannot be automatically installed, during installation, a part of the staff needs to operate to make the corrugated plate 4 close to the column 3, while another part of the staff screws the bolts and nuts on the connection points of the corrugated plate 4 and the column 3 to complete the connection between the two. Therefore, it takes multiple people to complete the work. In order to improve work efficiency and reduce the use of manpower, in one embodiment, a twisting mechanism is provided in the fixed plate 1, the twisting mechanism is connected to the traction chain transmission, nuts are placed on the twisting mechanism, bolts are placed on the movable plate 2, and the twisting mechanism drives the nuts to rotate for connection with the bolts;

[0037] By arranging a twisting mechanism on the fixed plate 1, the twisting mechanism is connected to the traction chain transmission. When the traction chain pulls the movable plate 2 to move toward the guide port 17, the traction action of the traction chain will also drive the rotation of the twisting mechanism. Therefore, a nut can be placed on the twisting mechanism, and a bolt can be placed on the movable plate 2, so that the bolt first penetrates the connection point of the corrugated plate 4, and the connection point of the column 3 is between the bolt and the nut. Since the movable plate 2 will push the corrugated plate 4 from a straight shape to an arc shape under the action of the traction chain, the corrugated plate 4 has a tendency to reset, so that the corrugated plate 4 can be abutted against the movable plate 2 with reverse force. In order to prevent the corrugated plate 4 from separating from the bolt during the movement, the bolt and the corrugated plate 4 can be connected in advance through another nut. After placing the bolts and nuts on the movable plate 2 and the twisting mechanism respectively, the movable plate 2 is pulled into the guide opening 17 by the traction chain. During the pulling process of the traction chain, the twisting mechanism will rotate accordingly, thereby driving the bolts on the twisting mechanism to rotate until the bolts and nuts abut and are gradually screwed in. After the movable plate 2 is completely pushed into the guide opening 17, the bolts and nuts form a preliminary connection, and the corrugated plate 4 and the column 3 also form a preliminary connection. After that, the bolts and nuts can be manually tightened to fix them.

[0038] Specifically, the twisting mechanism includes a first gear 12, a first screw rod 11 and a turntable 13. A traction channel 16 is provided on the fixed plate 1 for passing the traction chain. The first gear 12 is coaxially connected with the first screw rod 11. The first screw rod 11 is rotatably connected to the fixed plate 1 and meshed with the turntable 13. The turntable 13 is provided with a first mounting groove leading to the outside of the fixed plate 1 for placing a nut. The rim surface of the first gear 12 is tangent to the traction channel 16 and is transmission-connected to the traction chain.

[0039] The traction chain passes through the traction channel 16, and the teeth on the first gear 12 are meshed with the traction chain. The action of the traction chain pulling the movable plate 2 will synchronously drive the rotation of the first gear 12. Since the first gear 12 is transmission-connected with the first screw rod 11, that is, the first gear 12 is sleeved on the outside of the first screw rod 11, when the first gear 12 rotates, the first screw rod 11 also rotates. Since the rim surface of the turntable 13 is also provided with teeth, the first screw rod 11 and the teeth on the turntable 13 are also meshed with each other. The rotation of the first screw rod 11 will drive the turntable 13 to rotate. The first screw rod 11 and the turntable 13 form a transmission structure similar to a worm gear, and the first mounting groove on the side of the turntable 13 can place a nut. The turntable 13 is provided with an opening on the side of the fixed plate 1 facing the movable plate 2 for connection with a bolt. The pulling of the traction chain will drive the bolt to approach the nut and can be tightened synchronously with the bolt. The work of installing the corrugated plate 4 on the column 3 can be completed by only one staff member, which greatly improves the work efficiency.

[0040] On the other hand, since the traction chain is engaged with the first gear 12, and the first gear 12 is connected to the first screw rod 11, and the first screw rod 11 is engaged with the turntable 13, the nut on the turntable 13 and the bolt on the movable plate 2 are tightened while the movable plate 2 is pulled closer by the traction chain. After the two are tightened, they can serve as a non-return device for the traction chain, which can prevent the traction chain from being pulled in the reverse direction under the reverse force of the corrugated plate 4. The closer the nut and the bolt are screwed, the smaller the displacement of the traction chain caused by the reverse pull of the corrugated plate 4. Even in the absence of external force, the traction chain will not be easily pulled in the reverse direction.

[0041] Since in the above embodiment, transmission is performed only by meshing the first screw rod 11 with one side of the rotating disk 13, the teeth on the first screw rod 11 and the rotating disk 13 are subjected to a large force during transmission. After long-term use, the teeth on the first screw rod 11 and the rotating disk 13 will reach the fatigue strength of the metal, affecting the reliability of operation. In order to improve the reliability of the equipment, in one embodiment, the twisting mechanism further includes a second gear 15 and a second screw rod 14, the second gear 15 is coaxially connected to the second screw rod 14, the second screw rod 14 is arranged parallel to the first screw rod 11 and meshed with the other side of the rotating disk 13, and the first gear 12 and the second gear 15 are meshed with each other;

[0042] While driving the first screw rod 11 to rotate, the first gear 12 also drives the second gear 15 to rotate. The rotation of the second gear 15 can drive the second screw rod 14 to rotate, and then the turntable 13 is synchronously driven by the second screw rod 14. The first screw rod 11 and the second screw rod 14 drive the turntable 13 at the same time, which can reduce the pressure on a single side of the turntable 13 at the same time, and can increase the service life of the turntable 13 and the first screw rod 11 and the second screw rod 14, and improve the reliability of the equipment. Since the first screw rod 11 and the second screw rod 14 on both sides of the turntable 13 are at their respective meshing points, one side of the turntable 13 rotates upward and the other side of the turntable 13 rotates downward. Therefore, after being driven by the first gear 12 and the second gear 15, in order for the first screw rod 11 and the second screw rod 14 to drive the turntable 13 to rotate in the same direction, the thread directions of the first screw rod 11 and the second screw rod 14 need to be the same.

[0043] When the movable plate 2 pushes the corrugated plate 4 to move, although the corrugated plate 4 is first fixed by bolts in the above embodiment, the corrugated plate 4 may still be separated from the movable plate 2 under the stress generated by its own deformation. In order to prevent this problem, in one embodiment, a transverse groove 23 is provided on the movable plate 2 for limiting the position of the corrugated plate 4, and a second mounting groove 24 corresponding to the position of the first mounting groove is provided on the transverse groove 23 for placing the bolt; wherein the first mounting groove and the second mounting groove 24 are both hexagonal and can just accommodate nuts and bolts. In order to prevent the bolts or nuts from falling off, An elastic telescopic structure can be set in the first mounting groove and the second mounting groove 24. The telescopic structure protrudes from the inner side wall of the first mounting groove and the second mounting groove 24. It resists the force and retracts during the process of pushing the nut and the bolt into the first mounting groove and the second mounting groove 24. After the nut and the bolt are completely in the first mounting groove and the second mounting groove 24, it extends out again for limiting, which can improve the stability of the bolt and the nut. After the bolt and the nut are gradually tightened, the bolt and the nut will push the telescopic structure to retract, and the nut and the bolt will synchronously disengage from the first mounting groove and the second mounting groove 24.

[0044] Since in the above embodiment, the bolt is placed in the second installation groove 24, and the nut is placed in the first installation groove, the bolt and the nut are automatically tightened by the twisting mechanism when the movable plate 2 approaches, and when the bolt abuts against the nut, the connection point of the corrugated plate 4 has not yet coincided with the connection point on the column 3. If the guide opening 17 is completely in an inclined state, it is difficult for the movable plate 2 to completely align the bolt with the connection point on the column 3 and connect with the bolt, which easily leads to a high probability of connection failure. In order to solve this problem, in one embodiment, the guide opening 17 of the fixed plate 1 includes a uniform cross-section section and a variable cross-section section, the inner walls on both sides of the variable cross-section section are inclined surfaces, and the inner walls on both sides of the uniform cross-section section are vertical surfaces;

[0045] like Figure 7As shown, the guide opening 17 at the variable-section section is an enlarged and inclined shape toward one side of the movable plate 2. When the movable plate 2 moves to the variable-section section, it is used to correct the position of the movable plate 2, and the side walls on both sides of the guide opening 17 of the equal-section section are parallel to each other. Therefore, when the movable plate 2 moves to the equal-section section, it means that the guide opening 17 variable-section section has completed the position correction of the movable plate 2. At this time, the connection point of the bolt coincides with the connection point on the column 3 and also coincides with the nut. The movable plate 2 continues to move at the equal-section section, so that the bolt and the nut gradually approach and connect, completing the installation of the corrugated plate 4 and the column 3.

[0046] Since the connection between the column 3 and the corrugated plate 4 needs to be completed through multiple connection points, multiple bolts and nuts are required. Therefore, in one embodiment, two sets of twisting mechanisms are symmetrically arranged on both sides of the traction channel 16, and two sets of second mounting grooves 24 are correspondingly provided on the movable plate 2; the two first gears 12 on the two sets of twisting mechanisms on both sides of the traction channel 16 are engaged with the traction chain at the same time, and are transmitted through the traction chain at the same time.

[0047] Furthermore, the traction mechanism also includes a drum machine, which is arranged in the fixed plate 1. The drum machine is connected to the traction chain for recovering and releasing the traction chain. The drum machine can roll up and recover the excess traction chain, and release the traction chain when installing the corrugated plate 4 and the column 3. The drum machine can automatically retract, and there is no need to manually pull the traction chain, thereby reducing the use of manpower.

[0048] In order to reduce the traction force applied by the drum machine to the traction chain, so as to reduce the volume of the drum machine and make the equipment portable, in one embodiment, a pulley 22 is provided on the movable plate 2, one end of the traction chain is connected to the front end of the fixed plate 1, and the other end of the traction chain is passed through the pulley 22 and passes through the traction channel 16 to be connected to the drum machine; according to the principle of the labor-saving pulley 22, a pulley 22 is provided on the movable plate 2, and one end of the traction chain is connected to the fixed plate 1, and then the traction chain is pulled toward one side of the fixed plate 1, so that the traction force can be reduced to half of the original force. The reduction in traction force can reduce the volume of the drum machine and make the equipment more portable.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. 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.
