Description

Technical Field

[0001] This application relates to the technical field of highway traffic safety facility installation, and particularly relates to a construction layout device for installing corrugated beam guardrails. Background Technique

[0002] The corrugated beam guardrail is a combined corrugated plate movable steel guardrail used at the opening of the highway central isolation belt. The guardrail consists of two corrugated steel guardrail plates and two columns fixedly clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrail plates. During normal operation of the highway, the guardrail can be conveniently inserted into the pre-set insertion holes at the opening by inserting and pulling out the columns, playing a role of isolation and protection. At the same time, it echoes with the guardrail belt on the outer side of the highway, being neat, uniform, and aesthetically matched. When a vehicle collides with it, due to the good anti-collision performance and energy absorption effect of the corrugated steel guardrail plate, it is not easily damaged, and at the same time, it can play a good protective role for the vehicle and the drivers and passengers.

[0003] The related technology can refer to the Chinese patent with the publication number CN211617536U, which discloses a special vehicle for installing corrugated guardrail plates, including a transport vehicle body, a transport box, guide rail columns, a sliding frame, a telescopic arm, and a fixture. The telescopic arm includes a telescopic main arm, a first secondary arm, a first driving member, a second secondary arm, and a second driving member. The fixture includes a second clamping plate and a first clamping plate. The guardrail plates are transported to the installation site by the special vehicle, and the sliding frame provides an installation base for the telescopic arm. When installing the guardrail plates, the second driving member drives the second secondary arm to slide away from the first secondary arm, driving the second clamping plate to slide away from the first clamping plate, realizing an increase in the corrugated clamping opening, facilitating the workers to lift the guardrail plate and place it into the clamping opening between the second clamping plate and the first clamping plate. The second driving member drives the second secondary arm to slide towards the first secondary arm, driving the second clamping plate to slide towards the first clamping plate, realizing the clamping and fixing of the guardrail plate. The first driving member drives the first secondary arm to slide away from the telescopic main arm, driving the second clamping plate, the first clamping plate, and the guardrail plate together to slide towards the column, facilitating the workers to screw the guardrail plate and the column. With the second clamping plate and the first clamping plate provided, on the one hand, there is no need for workers to apply force to support the guardrail plate anymore, liberating the workers' hands and effectively reducing the labor intensity of installing the guardrail plate. On the other hand, it effectively prevents the guardrail plate from falling during the installation process, reducing the possibility of accidents.

[0004] In view of the above related technology, the special vehicle needs to stop every certain distance along the road while carrying the guardrail plates. Workers stack some of the guardrail plates in the vehicle onto the road surface, and this process usually requires the use of a forklift. Subsequently, the special vehicle returns to the starting point of the road. After the workers place the guardrail plates on the road surface under the fixture, the above structure is used to send the guardrail plates to the appropriate position to be connected to the columns. The process of placing the guardrail plates from the special vehicle onto the road surface increases the labor cost and the use cost of the forklift or other transportation equipment. Content of the Utility Model

[0005] In order to reduce the installation cost of the guardrail, the present application provides a construction layout device for installing a corrugated beam guardrail.

[0006] The present application provides a construction layout device for installing a corrugated beam guardrail, adopting the following technical solutions:

[0007] A construction layout device for installing a corrugated beam guardrail includes a transport vehicle. A box body is provided on the transport vehicle. An outlet is provided on one side of the box body in the same direction as the traveling direction of the transport vehicle. A blocking door is provided at the outlet. The lower end of the blocking door is hinged to the box body. A conveying device for conveying the guardrail plate in the box body to the installation position is provided in the box body.

[0008] By adopting the above technical solutions, the staff can open the blocking door and directly convey the guardrail plate from the box body to the installation position through the conveying device, eliminating the process of unloading the guardrail plate from the vehicle to the road surface and then loading the guardrail plate under the special vehicle fixture, effectively reducing the labor cost and the use cost of the transportation equipment during the installation process of the guardrail plate.

[0009] Optionally, the conveying device includes a clamping assembly for clamping the guardrail plate and two telescopic assemblies for driving the clamping assembly to move. The two telescopic assemblies are respectively located on both sides of the outlet. The telescopic assemblies are slidably connected to the box body in the vertical direction.

[0010] By adopting the above technical solutions, the clamping assembly can convey the guardrail plate from the box body to the outside of the box body under the drive of the telescopic assembly, and at the same time, the clamping assembly can also stably clamp the guardrail plate, thereby avoiding the falling off of the guardrail plate during the conveying process and improving the stability and safety of the conveying process.

[0011] Optionally, the telescopic assembly includes a telescopic seat and a telescopic arm. The telescopic seat is located in the box body and is slidably connected to the box body in the vertical direction. The telescopic arm is inserted into the telescopic seat and is slidably connected to the telescopic seat in a direction perpendicular to the side of the telescopic seat close to the outlet.

[0012] By adopting the above technical solutions, by using the settings of the telescopic seat and the telescopic arm, the clamping assembly can not only move in the vertical direction but also move in the horizontal direction, so that the guardrail plate can be conveyed to different installation positions and distances, enhancing the flexibility and adaptability of the device.

[0013] Optionally, the clamping assembly includes a first clamping plate and a second clamping plate. At the upper end surface of each telescopic arm, a clamping seat with an open upper end surface is fixedly provided. Inside the opening of the clamping seat, there are a first sliding rod and a second sliding rod. A bidirectional lead screw with an axis arranged along the sliding direction of the telescopic arm is rotatably connected inside the clamping seat. A driving motor for driving the bidirectional lead screw to rotate is provided on one side of the clamping seat close to the telescopic seat. Both the first sliding rod and the second sliding rod are threadedly connected to the bidirectional lead screw and are slidably connected to the clamping seat in opposite directions. The first clamping plate is located between the two first sliding rods and is fixedly connected to the two first sliding rods. The second clamping plate is located between the two second sliding rods and is fixedly connected to the two second sliding rods. The telescopic seat is provided with an avoidance groove for avoiding the clamping seat.

[0014] By adopting the above technical solution, the driving motor drives the bidirectional lead screw to rotate, which can make the first sliding rod and the second sliding rod slide in opposite directions, so as to realize the clamping or loosening action of the first clamping plate and the second clamping plate on the guardrail plate, facilitating the clamping or putting down of the guardrail plate and improving the working efficiency.

[0015] Optionally, at one end of the telescopic seat away from the discharge port, a lifting assembly for driving the telescopic seat to lift is provided.

[0016] By adopting the above technical solution, the lifting assembly can drive the telescopic seat and the clamping assembly to lift, so as to be able to adapt to the installation requirements of different heights and make the application range of the equipment wider.

The threaded rod is rotatably connected to the limiting frame. The threaded rod is vertically arranged and is threadedly connected to the telescopic seat. The lifting motor is located on the upper end surface of the limiting frame and is used for driving the threaded rod to rotate.

[0018] By adopting the above technical solution, the lifting motor drives the threaded rod to rotate, which can make the telescopic seat lift in the limiting frame. Therefore, the height adjustment of the clamping assembly can be realized, further improving the flexibility and application range of the equipment.

[0019] Optionally, a connecting beam is fixedly provided between the two telescopic seats.

[0020] By adopting the above technical solution, the two telescopic seats are fixedly connected by the connecting beam, effectively enhancing the structural stability between the two telescopic seats, making the two telescopic seats lift synchronously, and improving the service life and safety of the equipment.

[0021] Optionally, the cross-section of the connecting beam in the vertical direction is triangular, and the side of the connecting beam away from the discharge port is an inclined surface.

[0022] By adopting the above technical solution, the guardrail plate is pre-placed on the inclined surface of the connecting beam. After the clamping assembly returns to the box body, the guardrail plate is turned upward so that the guardrail plate falls between the first clamping plate and the second clamping plate, reducing the lifting height of the guardrail plate and saving manpower.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The staff can open the blocking door and directly convey the guardrail plate from the box body to the installation position through the conveying device, eliminating the process of unloading the guardrail plate from the vehicle to the road surface and then loading the guardrail plate under the special vehicle fixture, effectively reducing the labor cost and the use cost of transportation equipment during the installation process of the guardrail plate;

Detailed implementation manners

[0033] The following further elaborates on this application in conjunction with all the attached drawings.

[0034] An embodiment of this application discloses a construction layout device for installing corrugated beam guardrails.

[0035] Refer to Figure 1 , a construction layout device for installing corrugated beam guardrails, including a transport vehicle 1. A box body 2 is provided on the transport vehicle 1. The box body 2 is provided with a discharge port on the side in the same direction as the traveling direction of the transport vehicle 1. A retaining door 21 is provided at the discharge port, and the lower end of the retaining door 21 is hinged to the box body 2 so that it can rotate around the hinge point to open or close the discharge port. A conveying device 3 for conveying the guardrail plate from the inside of the box body 2 to the installation position is arranged inside the box body 2.

[0036] Refer to Figure 2 , the conveying device 3 is composed of a clamping assembly 31 and two sets of telescopic assemblies 32. These two sets of telescopic assemblies 32 are respectively arranged on both sides of the discharge port, and each telescopic assembly 32 can be slidably connected to the box body 2 in the vertical direction. In this way, the clamping assembly 31 can be driven by the telescopic assembly 32 to move in the vertical direction, so as to convey the guardrail plate from the inside of the box body 2 to the outside of the box body 2.

[0037] Refer to Figure 2 , each telescopic assembly 32 includes a telescopic seat 321 and a telescopic arm 322. The telescopic seat 321 is installed inside the box body 2 and can be slidably connected to the box body 2 in the vertical direction. The telescopic arm 322 is inserted into the telescopic seat 321 and can be slidably connected to the telescopic seat 321 in a direction perpendicular to the side of the telescopic seat 321 close to the discharge port, and can extend to the outside of the box body 2. A driving device is installed inside the telescopic seat 321 to drive the telescopic arm 322 to move. In this way, through the combined use of the telescopic seat 321 and the telescopic arm 322, the clamping assembly 31 can move in a two-dimensional plane, not only can it move in the vertical direction, but also can move in the horizontal direction.

[0038] Refer to Figure 3 and Figure 4, the clamping assembly 31 includes a first clamping plate 311 and a second clamping plate 312, which are used to stably clamp the guardrail plate. The opposite surfaces of the first clamping plate 311 and the second clamping plate 312 are adapted to the shape of the guardrail plate, and can be completely in contact with the guardrail plate, increasing the contact area and improving the fastening of the clamping. A clamping seat 313 with an open upper end face is fixed to the upper end face of each telescopic arm 322. Inside the opening of the clamping seat 313, a first sliding rod 314 and a second sliding rod 315 are provided. A bidirectional lead screw 316 with an axis arranged along the sliding direction of the telescopic arm 322 is rotatably connected inside the clamping seat 313. On one side of the clamping seat 313 close to the telescopic seat 321, a driving motor 317 capable of driving the bidirectional lead screw 316 to rotate is installed. Both the first sliding rod 314 and the second sliding rod 315 are threadedly connected to the bidirectional lead screw 316, and they slide in the opposite direction to the clamping seat 313. Two first clamping plates 311 are arranged between the two first sliding rods 314, and the two first sliding rods 314 and the two first clamping plates 311 are fixedly connected by setting connecting rods. Similarly, two second clamping plates 312 are arranged between the two second sliding rods 315, and the two second sliding rods 315 and the two second clamping plates 312 are also fixedly connected by setting connecting rods. An avoidance groove 3211 is also opened on the telescopic seat 321, which is used to avoid the clamping seat 313 when the telescopic arm 322 retracts into the telescopic seat 321.

[0039] Refer to Figure 2 , at one end of the telescopic seat 321 away from the discharge port, a lifting assembly 4 is provided, which is used to drive the telescopic seat 321 to lift, so as to adjust the height of the clamping assembly 31 to meet the installation requirements of different heights.

[0040] Refer to Figure 4 and Figure 5 , the lifting assembly 4 is composed of a limit frame 41, a threaded rod 42 and a lifting motor 43. The inner wall of the limit frame 41 is in close contact with the telescopic seat 321 to ensure the stability of its vertical lifting. The threaded rod 42 is rotatably connected to the limit frame 41 and is arranged vertically. The threaded rod 42 is threadedly connected to the telescopic seat 321. In this way, when the threaded rod 42 rotates, it can drive the telescopic seat 321 to lift. The lifting motor 43 is installed on the upper end face of the limit frame 41 and is used to drive the threaded rod 42 to rotate.

[0041] Driven by the lifting motor 43, the threaded rod 42 rotates, thereby driving the telescopic seat 321 and the clamping assembly 31 to lift. This design enables the equipment to meet the installation requirements of different heights, further enhancing the flexibility and application range of the equipment.

[0042] Refer to Figure 2 , a connecting beam 5 is also fixedly connected between the two telescopic seats 321, which is used to enhance the structural stability between the two telescopic seats 321.

[0043] Reference Figure 5 , the vertical cross-section of the connecting beam 5 is triangular, and the side away from the discharge port is designed as an inclined surface 51. In this way, the staff can pre-place the guardrail plate on the inclined surface 51 of the connecting beam 5. When the clamping assembly 31 returns to the box body 2, the guardrail plate is turned upward so that it falls between the first clamping plate 311 and the second clamping plate 312. This design reduces the lifting height of the guardrail plate and further saves manpower.

[0044] It is also possible to set a track above the box body 2. A cross beam slides on the track. An electric hoist is installed on the cross beam. The electric hoist is connected to a spreader, and the spreader is used to clamp the guardrail plate. In this way, it is not necessary for the staff to manually place the guardrail plate into the clamping assembly 31. The staff uses the spreader to fix the guardrail plate, and then operates the electric hoist to lift and lower. The cross beam slides on the track to send the guardrail plate into the clamping assembly 31. This further saves the number of staff and manpower.

[0045] The implementation principle of the construction layout equipment for installing corrugated beam guardrails in the embodiment of the present application is as follows: First, the staff opens the door 21, places the guardrail plate between the first clamping plate 311 and the second clamping plate 312, and then drives the motor 317 to drive the bidirectional lead screw 316 to rotate, so that the first slide rod 314 and the second slide rod 315 slide in opposite directions. In this way, the first clamping plate 311 and the second clamping plate 312 can clamp the guardrail plate. Next, driven by the telescopic assembly 32, the clamping assembly 31 transports the guardrail plate from the box body 2 to the installation position. The whole process omits the process of unloading the guardrail plate from the vehicle to the road surface and then loading the guardrail plate under the special vehicle fixture, effectively reducing the labor cost and the use cost of transportation equipment during the installation process of the guardrail plate.

[0046] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
