Description

Technical Field

[0001] This application relates to the field of traffic engineering technology, and in particular to a height-adjustable guardrail for traffic engineering. Background Technology

[0002] Traffic engineering is a branch of transportation engineering, which includes five aspects: road traffic, rail traffic, air traffic, water traffic, and pipeline traffic. Road traffic engineering is traffic on roads, specifically public roads where cars and other means of transportation can travel, including cars, bicycles, rickshaws, horses, and pedestrians. Of course, different roads have different restrictions.

[0003] The height of height-adjustable guardrails used in traffic engineering in related technologies is fixed and inconvenient, making it difficult to adjust the height and adapt to different working conditions, thus affecting the protective function of the guardrail itself.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem that the height of adjustable guardrails used in traffic engineering is inconvenient to fix at a fixed height, making it impossible to adjust the height and thus unsuitable for different working conditions, thereby affecting the protective function of the guardrail itself, this application provides a height-adjustable guardrail for traffic engineering.

[0006] This application provides a height-adjustable guardrail for traffic engineering, which adopts the following technical solution:

[0007] A height-adjustable guardrail for traffic engineering includes two symmetrically installed posts, two horizontal plates that are symmetrically slidably arranged between the two posts, a plurality of protective components installed between the two horizontal plates, and a driving component for driving the two horizontal plates to move up and down on the posts. The driving component includes a bidirectional lead screw rotatably arranged between the two posts, and two threaded blocks symmetrically threaded to the outer side of the bidirectional lead screw. A connecting rod is hinged between the threaded blocks and the horizontal plates.

[0008] Preferably, the two columns are provided with symmetrical lifting grooves at their near ends, the horizontal plate extends into the interior of the lifting groove, and a sliding column that penetrates the horizontal plate is fixedly installed inside the lifting groove.

[0009] Preferably, one end of the bidirectional lead screw passes through the side wall of one of the columns and is fixedly mounted with a drive disc, the drive disc having multiple anti-slip grooves in the circumferential direction.

[0010] Preferably, the protective component includes a protective sleeve fitted on the outside of the bidirectional lead screw, with grooves at both ends of the protective sleeve, and a protective rod slidably disposed inside the grooves, the protective rod being fixedly connected to the cross plate.

[0011] Preferably, a support base is fixedly installed at the bottom of each of the two columns, and an anti-slip pad is fixedly installed at the bottom of the support base.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. This application has a horizontal plate that slides between two columns, and is equipped with a two-way screw, a threaded block and a connecting rod. By rotating the two-way screw, the two-way screw can push the two threaded blocks closer or further apart. The threaded blocks push the connecting rod to change the angle, thereby moving the horizontal plate and adjusting the protection height of the device, thus improving the practicality of the device.

[0014] 2. This application improves the stability of the horizontal plate by providing a lifting groove on the column and a sliding column to limit the vertical movement of the horizontal plate. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a height-adjustable guardrail for traffic engineering, referring to... Figure 1-3It includes two symmetrically installed columns 1, two horizontal plates 3 that are symmetrically slidably arranged between the two columns 1, multiple protective components 4 installed between the two horizontal plates 3, and a drive component 5 for driving the two horizontal plates 3 to move up and down on the columns 1. The drive component 5 includes a bidirectional lead screw 51 that is rotatably arranged between the two columns 1. Two threaded blocks 52 are symmetrically threaded on the outer side of the bidirectional lead screw 51. A connecting rod 53 is hinged between the threaded blocks 52 and the horizontal plates 3.

[0021] By rotating the bidirectional lead screw 51, the bidirectional lead screw 51 can push the two threaded blocks 52 closer to each other or further apart. The threaded blocks 52 push the connecting rod 53 to rotate, and the connecting rod 53 can push the two horizontal plates 3 closer to each other or further apart, so that the height of the protection can be adjusted, improving the practicality of the device.

[0022] Reference Figure 1 Two columns 1 are symmetrically provided with lifting grooves 2 at their near ends. A horizontal plate 3 extends into the interior of the lifting groove 2, and a sliding column 21 that passes through the horizontal plate 3 is fixedly installed inside the lifting groove 2.

[0023] Here, a lifting groove 2 is provided, and a sliding column 21 is provided to limit the movement of the horizontal plate 3.

[0024] Reference Figure 2 One end of the bidirectional lead screw 51 passes through the side wall of one of the columns 1 and is fixedly installed with a drive disc 54. Multiple anti-slip grooves are provided on the circumference of the drive disc 54.

[0025] Here, a drive disk 54 is provided, and anti-slip grooves are provided on the drive disk 54 to facilitate the rotation of the bidirectional lead screw 51.

[0026] Reference Figure 3 The protective component 4 includes a protective sleeve 41 sleeved on the outside of the bidirectional lead screw 51. Both ends of the protective sleeve 41 are provided with grooves 411. A protective rod 42 is slidably arranged inside the grooves 411. The protective rod 42 is fixedly connected to the cross plate 3.

[0027] Here, by providing grooves 411 at both ends of the protective sleeve 41 and providing protective rods 42, the height of the two horizontal plates 3 can be adjusted, thereby adjusting the protective height.

[0028] Reference Figure 1 Both columns 1 are fixedly installed with support bases 6 at their bottoms, and anti-slip pads 7 are fixedly installed at the bottom of the support bases 6.

[0029] The support base 6 and anti-slip pad 7 are provided here to provide stable support for the column 1.

[0030] The implementation principle of a height-adjustable guardrail for traffic engineering in this application embodiment is as follows: When in use, the device is placed in a designated position, and then the drive disc 54 is rotated. The drive disc 54 drives the bidirectional lead screw 51 to rotate. The bidirectional lead screw 51 can push two threaded blocks 52 to move closer or further apart. The threaded blocks 52 push the connecting rod 53 to rotate. The connecting rod 53 can push two horizontal plates 3 to move closer or further apart, so that the height of the guardrail can be adjusted, improving the practicality of the device.
