DETAILED DESCRIPTION

[0044] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0045] Highway expansion refers to widening, renovating and upgrading existing highways to increase road capacity, improve traffic conditions, and increase transportation efficiency and safety. The reasons for highway expansion usually include the following:

[0046] 1. Traffic flow growth: With the development of regional economy and population increase, the traffic flow of the original highway exceeds its design carrying capacity, resulting in traffic congestion. 2. Improve traffic safety: Reduce the possibility of accidents by improving road conditions, such as increasing lane width and improving curve radius. 3. Adapt to new traffic needs: For example, adapt to the development of large truck transportation and public transportation.

[0047] During highway expansion, the isolation of old and new roads is usually to ensure construction safety and traffic order, prevent debris and equipment in the construction area from entering normal roads, avoid traffic accidents, reduce the interference of construction on normal traffic flow, ensure the safety of vehicles and pedestrians, and provide a relatively safe working environment for construction personnel. The current isolation method is nothing more than the use of guardrails. First, the base is fixed in the corresponding area with screws, the distance between the bases is measured in advance, and then the column is inserted into the base. Finally, the guardrail frame is inserted into the sockets on both sides of the column to complete the installation of the isolation guardrail. However, this setting has the following limitations in actual use;

[0048] First, there may be a height difference at the junction of the new and old roads, and the existing slots and columns are generally fixed, so when installing the isolation frame, there will be a height mismatch and it cannot be installed; at the same time, in some temporary isolation areas, the base is generally placed directly on the road surface and does not need to be fixed, so the stability of the isolation device cannot be guaranteed. The new and old road isolation device for highway expansion provided in this application has an adjustable fixed position of the mounting frame on the column, so that the mounting frames on two columns at different heights can be in the same plane, which is convenient for the installation and use of the isolation frame.

[0049] The specific structure of the new and old road isolation device for highway expansion provided in this application is described in detail below in conjunction with the accompanying drawings.

[0050] Reference Figure 1-Figure 8 As shown, the embodiment of the present application provides a new and old road isolation device for highway expansion, including a column 1, a mounting frame 2 and an isolation frame 3;

[0051] The isolation frame 3 is a conventional guardrail, with columns 1 provided at both ends of the isolation frame 3, mounting frames 2 provided on both sides of the columns 1, and the ends of the isolation frame 3 connected to the mounting frames 2;

[0052] like Figure 2 and Figure 3 As shown, the left and right walls of the column 1 are both provided with first screw holes 13, and the multiple first screw holes 13 on the same side are distributed along the height direction of the column 1, that is, arranged vertically;

[0053] The mounting frame 2 includes a connecting plate 21 and a sleeve 22. The connecting plate 21 can be a vertically arranged rectangular plate body, and the sleeve 22 can be a square sleeve. The connecting plate 21 is provided with a mounting hole 23, and a bolt is inserted into the mounting hole 23. The bolt is screwed with the first screw hole 13. The sleeve 22 is arranged on the side of the connecting plate 21 facing away from the column 1; the end of the isolation frame 3 is plugged into the sleeve 22;

[0054] A plurality of first screw holes 13 are vertically provided on the column 1. After the bolts pass through the mounting holes 23 of the mounting frame 2, they can be connected to the first screw holes 13 at different heights, thereby fixing the mounting frame 2 at any height position of the column 1, so that the mounting frames 2 on two columns 1 at different heights are at the same height, thereby facilitating the fixation of the isolation frame 3.

[0055] Reference Figure 2-Figure 4 As shown, in some embodiments, the column 1 includes a column 11 and a support rod 12;

[0056] The column 11 and the support rod 12 can be made of metal, the support rod 12 can be a square rod, the column 11 is vertically arranged, the left and right sides of the column 11 are provided with a first screw hole 13, the bottom end of the column 11 is provided with a plug hole 14, the plug hole 14 can be a square hole matching the support rod 12, and the middle part of the column 11 is provided with a second screw hole 15 connected to the plug hole 14;

[0057] The support rod 12 is provided with a connection hole 16, and the plurality of connection holes 16 are distributed along the height direction of the support rod 12, that is, the plurality of connection holes 16 are vertically distributed in the middle of the support rod 12;

[0058] The support rod 12 is plugged into the socket 14 of the column 11, and a limiting bolt is connected in the second screw hole 15. The limiting bolt passes through the connecting hole 16. The connecting holes 16 of different heights are connected by the limiting bolt, so the overall height of the column 1 can be adjusted, and the height of the mounting frame 2 can be adjusted, so that the isolation device can be used in different areas, and even if collision damage occurs, since the isolation frame, column, mounting frame and support rod are all split designs, their parts can be freely combined without replacing the whole, saving costs, and the device is connected by bolt combination, and the device can be installed and disassembled.

[0059] In some embodiments, the column 1 further includes a guide block 17, and the vertical interface of the guide block 17 may be T-shaped;

[0060] Guide blocks 17 are provided on both sides of the column 11 , and a guide groove is formed between the column 11 and the guide blocks 17 . The outer wall of the connecting plate 21 is slidably connected to the inner wall of the guide groove, so as to facilitate the movement and adjustment of the mounting frame 2 .

[0061] In some embodiments, the column 1 further includes a base 18;

[0062] The base 18 may be a rubber base, and the base 18 is fixed to the bottom end of the support rod 12 .

[0066] The fixing plate 41 may be a rectangular strip, and the fixing plate 41 is fixedly mounted at the bottom end of the isolation frame 3, and the fixing plate 41 is vertically arranged, and grooves are provided on both sides of the fixing plate 41, and the grooves may be rectangular grooves;

[0067] The rotating plate 42 can be a rectangular plate body, and the two rotating plates 42 are respectively rotatably arranged on the left and right sides of the bottom end of the fixed plate 41 through the rotating shaft, and the rotating plates 42 are inserted into the groove, and there is a certain gap between the outer wall of the rotating plate 42 and the inner wall of the inner end of the groove;

[0068] The spring 43 is arranged in the above-mentioned gap, and the two ends of the spring 43 are respectively connected to the inner wall of the inner end of the groove and the outer wall of the rotating plate 42;

[0069] The hook 44 is an arc-shaped metal hook, and the hook 44 is fixedly disposed on the side of the rotating plate 42 facing the rotating plate 42 .

The hook 44 is located in the groove, reducing the space occupied by the suspension component 4; Figure 6 As shown, when using the suspension assembly 4 for suspension configuration, rotate the rotating plate 42 outward until the rotating plate 42 is engaged with the blocking frame 45. At this time, the rotating plate 42 is inclined at 45°, and the counterweight is hung inside the hook 44 on one side of the rotating plate 42 to complete the counterweight and increase the stability of the device.

[0073] When temporary isolation is required, the base is generally not directly fixed to the ground by screws, but is generally placed directly in the isolation area. Under the influence of the external environment, the device is easy to topple over. For example, strong winds or touches can cause it to topple over. An external counterweight is hung on the outside of the hook 44. The counterweight can be a plastic bag with water, or other counterweight methods can be used to adjust the center of gravity of the device, thereby ensuring the stability of the device.
