Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance, in particular to a highway maintenance and repair device. Background Art

[0002] "Highway maintenance" refers to the upkeep and maintenance of highways. Maintenance focuses on the entire process from the time a highway is completed and opened to traffic, while repairs focus on repairing damaged parts.

[0003] During the highway maintenance and repair construction process, it is necessary to use railings to enclose the construction area. In order to prevent dust from spreading and polluting the environment, it is usually necessary to fix a higher baffle on the periphery of the railing. This enclosure method is very cumbersome and time-consuming to install, resulting in reduced work efficiency. In addition, the railings and baffles cannot be folded, resulting in increased transportation costs. Therefore, we propose a highway maintenance and repair device. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art. During the process of highway maintenance and repair construction, it is necessary to use railings to enclose the construction area. In order to prevent dust from spreading and polluting the environment, it is usually necessary to fix a higher baffle on the periphery of the railings. This type of enclosure is very cumbersome and time-consuming to install, resulting in reduced work efficiency. In addition, the railings and baffles cannot be folded, resulting in increased transportation costs.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A highway maintenance and repair device includes a guardrail, a baffle assembly being installed at the top of the guardrail;

[0007] The front side of the railing is threadedly connected to the left and right sides near the top, and an adjustment component is installed on the inner side of the railing;

[0008] The baffle assembly includes an upper baffle, a connecting plate is fixedly connected to the front of the upper baffle near the top, and sliding rods are symmetrically welded to the bottom of the connecting plate near the left and right sides.

[0009] As a preferred solution of the present invention, fixing bolts are symmetrically installed on the front and back sides of the bottom of the railing, close to the left and right sides.

[0010] The technical effect of adopting the above further solution is that the railing can be fixed to the ground by rotating the fixing bolts, making the railing more firm and improving the stability in use.

[0011] As a preferred solution of the present invention, the adjustment assembly includes a cross bar, which is welded to the inner side of the railing.

The left and right sides of the back side of the lower baffle are fixedly connected to limit rods, and the limit rods are slidably connected to the cross bar.

[0012] The technical effect of adopting the above-mentioned further scheme is: by rotating the second screw, the lower baffle can be driven to move forward and backward, so that the upper baffle and the lower baffle are flush, thereby improving the dust-proof effect. The limit rod can be used to limit the lower baffle during its movement to prevent it from rotating with the second screw, thereby improving the stability of use.

[0013] As a preferred solution of the present invention, the upper baffle and the lower baffle are both made of hollow PVC material.

[0014] The technical effect of adopting the above further solution is: the hollow PVC material of the upper baffle and the lower baffle can greatly reduce the weight of the upper baffle and the lower baffle, thereby reducing the overall weight of the equipment, facilitating transportation, and also making it easier for manual adjustment and installation, thereby improving ease of use.

[0015] As a preferred solution of the present invention, the connecting plate is made of L-shaped metal.

[0016] The technical effect of adopting the above further solution is that the upper baffle and the slide rod can be made more secure by the L-shaped metal connecting plate, thereby improving the stability in use.

[0017] As a preferred solution of the present invention, threaded openings are symmetrically opened on the front side of the slide rod near the top and the bottom, and the threaded openings are adapted to the first screw rod.

[0018] The technical effect of adopting the above further solution is: when the device is deployed and used, the sliding rod can be positioned by rotating the first screw to make it sink into the threaded opening, preventing the sliding rod from loosening during use and improving the stability of use.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In the utility model, through the design of the railing and baffle assembly, the sliding rod is pulled out of the railing, the first screw is rotated to fix the sliding rod, and the lower baffle is driven to move to the bottom of the upper baffle through the adjustment assembly to complete the deployment of the entire equipment. Compared with the traditional enclosure method, it greatly improves the operational convenience and effectively improves the work efficiency. At the same time, the equipment can be folded during transportation through the sliding rod, which reduces the occupancy of the transportation space and effectively reduces the transportation cost.

[0029] Example 1

[0030] like Figure 1-3 As shown, the utility model provides a technical solution: a highway maintenance and repair device, including a railing 1, a baffle assembly 2 is installed on the top of the railing 1, a first screw 101 is threadedly connected to the left and right sides of the front of the railing 1 near the top, an adjustment assembly 102 is installed on the inner side of the railing 1, the baffle assembly 2 includes an upper baffle 201, a connecting plate 202 is fixedly connected to the front of the upper baffle 201 near the top, and a sliding rod 203 is symmetrically welded to the bottom of the connecting plate 202 near the left and right sides.

[0031] Example 2

[0032] like Figure 1-3 The left and right sides of the back of the lower baffle 1023 are fixedly connected. The limit rod 1024 is slidably connected to the cross bar 1021. By rotating the second screw 1022, the lower baffle 1023 can be driven to move forward and backward, so that the upper baffle 201 and the lower baffle 1023 are flush with each other, thereby improving the dustproof effect. The limit rod 1024 can be used to limit the movement of the lower baffle 1023 to prevent it from following the second screw 10 22 rotates together to improve the stability of use. The upper baffle 201 and the lower baffle 1023 are both made of hollow PVC material. The hollow PVC material of the upper baffle 201 and the lower baffle 1023 can greatly reduce the weight of the upper baffle 201 and the lower baffle 1023, thereby reducing the overall weight of the equipment, making it easier to carry and more convenient to adjust and install manually, thereby improving the convenience of use. The connecting plate 202 is made of L-shaped metal material. The L-shaped metal connecting plate 202 can make the upper baffle 201 and the slide bar 203 more firm, thereby improving the stability of use. The front side of the slide bar 203 is symmetrically provided with threaded openings 2031 near the top and bottom, and the threaded openings 2031 are adapted to the first screw 101. When the equipment is unfolded and used, the slide bar 203 can be positioned by rotating the first screw 101 to make it immersed in the threaded opening 2031, thereby preventing the slide bar 203 from loosening during use and improving the stability of use.

[0033] The working process of the present invention is as follows: when using a road maintenance and repair device for shielding during road maintenance and repair, first use an external pneumatic wrench to rotate the fixing bolt 103 to fix the railing 1 to the ground, and then pull the sliding rod 203 out of the railing 1, so that the sliding rod 203 drives the upper baffle 201 to move upward. After moving to a suitable position, rotate the first screw 101 to make it sink into the threaded opening 2031 near the bottom of the sliding rod 203, so as to position the unfolded sliding rod 203, prevent the sliding rod 203 from loosening and sliding during use, and improve the stability of use. The second screw 1022 is turned to push the lower baffle 1023 to move to the bottom of the upper baffle 201 to complete the entire unfolding process. Compared with the traditional enclosure method, it greatly improves the convenience of operation and effectively improves work efficiency. After use, the slide bar 203 can be put back into the railing 1 for folding, and the first screw 101 is turned to sink it into the threaded opening 2031 near the top of the slide bar 203 to position the slide bar 203 to prevent it from sliding out of the railing 1, reducing the space occupied, making transportation more convenient, and effectively reducing transportation costs.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
