Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, and in particular to an isolation and protection device for road and bridge construction. Background Technology

[0002] When constructing roads and bridges, it is necessary to protect the safety of on-site workers and pedestrians, which means that the construction area needs to be isolated.

[0003] Commonly used isolation and protection devices are modular safety fences, which consist of fences or warning tapes used in conjunction with supports. However, during field maintenance, the working ground is often uneven soil rather than paved roads. In such cases, the supports may tip over due to instability, which is not conducive to safety protection. When using these fences, it is necessary to consider the site environment and adjust their position to isolate the construction site from the outside. Since the fences and supports are usually an integral structure, they are not easy to move or adjust in position, and the fences often have a single function. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an isolation and protection device for road and bridge construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A road and bridge construction isolation and protection device includes a base and an isolation net. A column is fixedly connected to the top of the base, and a hollow cavity is opened at the bottom of the column. The hollow cavity is connected to the bottom of the base. A fixing mechanism including a conical block is set in the hollow cavity. The top and bottom of the column are provided with mounting holes.

[0007] The isolation net includes grid strips and connecting shafts. Vertical partitions are provided on both sides of the isolation net. Several inclined grid strips are rotatably connected between the two partitions. Connecting shafts are fixedly connected to the top and bottom of the two partitions facing each other. A locking mechanism is provided at the end of the connecting shaft.

[0008] A conical block is slidably connected inside the hollow cavity. Hanging ears are fixedly connected to both sides of the top of the conical block. Inverted L-shaped grooves are symmetrically opened on the side walls of the columns on both sides of the hollow cavity. The horizontal section of the inverted L-shaped groove is located above the bottom mounting hole.

[0009] Preferably, a warning light is installed at the top of the column, and the warning light is electrically connected to the power supply at the construction site via an electrical wire.

[0010] Preferably, the bottom of the horizontal section of the two inverted L-shaped grooves has a placement groove at the bottom of the column, and the placement groove is connected to the hollow cavity.

[0011] Preferably, the sidewall of the lug is provided in a threaded hole, and a crossbar is threaded into the threaded hole.

[0012] Preferably, the end of the crossbar has a through hole, and a vertical bar is movably connected inside the through hole.

[0013] Preferably, the length of the connecting shaft is greater than the depth of the mounting hole, and the diameter of the connecting shaft is smaller than the inner diameter of the mounting hole.

[0014] Preferably, the locking mechanism includes a slot and a rotating block. The end of the connecting shaft has a slot, and the rotating block is rotatably connected in the slot. The rotating shaft of the rotating block is not located at the center of the rotating block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model features a base and columns. The base is easy to place on the construction ground, and the columns are used to install the isolation net. The conical blocks can be stored in the hollow cavity. During use, the number of columns and their placement can be reasonably selected according to the site environment to achieve sufficient isolation and ensure the safety of pedestrians and workers.

[0017] This utility model features a fixing mechanism that inserts a conical block into the ground to secure the column, thereby enabling the installation of the isolation net. This ensures the stability of the column and the isolation net during operation. Furthermore, once the isolation net is installed, the connecting shaft at the bottom can limit the top of the conical block, preventing accidental movement of the conical block from affecting the stability of the column.

[0018] This utility model features a conical block with a slot for easy placement of the hanging lugs. When not in use, the conical block can be placed on top of the hollow cavity without falling off. The crossbar can be manually threaded into the threaded hole during use, allowing the conical block to be operated via the crossbar. When not in use or during isolation, the crossbar can be removed to prevent accidental movement of the conical block. Similarly, the vertical bar can be used to suspend tools during the use of the isolation and protection device. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-6 A road and bridge construction isolation and protection device includes a base 1 and an isolation net 15. A column 2 is fixedly connected to the top of the base 1. A hollow cavity 4 is opened at the bottom of the column 2. The hollow cavity 4 is connected to the bottom of the base 1. A fixing mechanism 5 including a conical block 8 is provided in the hollow cavity 4. The top and bottom of the column 2 are provided with mounting holes 14.

[0028] The isolation net 15 includes grid strips 16 and connecting shafts 17. Vertical partitions are provided on both sides of the isolation net 15. Several inclined grid strips 16 are rotatably connected between the two partitions. Connecting shafts 17 are fixedly connected to the top and bottom of the two partitions. A locking mechanism 18 is provided at the end of the connecting shaft 17.

[0029] A conical block 8 is slidably connected inside the hollow cavity 4. Hanging ears 9 are fixedly connected to both sides of the top of the conical block 8. Inverted L-shaped grooves 6 are symmetrically opened on the side walls of the columns 2 on both sides of the hollow cavity 4. The horizontal section of the inverted L-shaped groove 6 is located above the bottom mounting hole 14. The base 1 is easy to place on the construction ground. The columns 2 are used to install the isolation net 15. The conical block 8 can be stored inside the hollow cavity 4. During use, the number of columns 2 and their placement positions can be reasonably selected according to the site environment to achieve sufficient isolation and ensure the safety of pedestrians and workers. The conical block 8 is inserted into the ground through the fixing mechanism 5 to fix the column 2 and install the isolation net 15, ensuring the stability of the columns 2 and the isolation net 15 during operation. After the isolation net 15 is installed, the connecting shaft 17 at the bottom can limit the top of the conical block 8, preventing accidental movement of the conical block 8 and affecting the stability of the column 2. The isolation net 15 can change its length by stretching the grid strips 16 to meet the isolation requirements of different spacing.

[0030] As a technical optimization of this utility model, a warning light 3 is installed at the top of the column 2, and the warning light 3 is electrically connected to the power supply at the construction site via an electrical wire. The warning light 3 is always on at the site, which can serve as a warning to pedestrians outside, preventing them from accidentally entering the isolated area. At the same time, it also reminds maintenance personnel to raise their safety awareness and carry out maintenance work in accordance with operating procedures.

[0031] As a technical optimization of this utility model, the bottom of the horizontal section of the two inverted L-shaped grooves 6 is provided with a placement groove 7, which is connected to the hollow cavity 4. The placement groove 7 facilitates the placement of the hanging ears 9, so that when not in use, the conical block 8 can be placed on the top of the hollow cavity 4 through the hanging ears without falling off.

[0032] As a technical optimization of this utility model, the side wall of the lug 9 is provided with a threaded hole 10, and a crossbar 11 is threadedly connected inside the threaded hole 10. When in use, the crossbar 11 can be manually threaded into the threaded hole 10, and the conical block 8 can be operated through the crossbar 11. When not in use or during isolation, the crossbar 11 can be removed to prevent accidental movement of the conical block 8.

[0033] As a technical optimization of this utility model, a through hole 12 is provided at the end of the horizontal bar 11, and a vertical bar 13 is movably connected in the through hole 12. Similarly, the vertical bar 13 can be used to suspend tools, etc., during the use of the isolation and protection device.

[0034] As a technical optimization of this utility model, the length of the connecting shaft 17 is greater than the depth of the mounting hole 14, and the diameter of the connecting shaft 17 is smaller than the inner diameter of the mounting hole 14. After the connecting shaft 17 is inserted into the mounting hole 14, a locking mechanism 18 is used to prevent the connecting shaft 17 from disengaging from the mounting hole 14.

[0035] As a technical optimization of this utility model, the locking mechanism 18 includes a slot 19 and a rotating block 20. The slot 19 is provided at the end of the connecting shaft 17, and the rotating block 20 is rotatably connected in the slot 19. The axis of rotation of the rotating block 20 is not located at the center of the rotating block 20. After the connecting shaft 17 is inserted into the mounting hole 14, the locking mechanism 18 allows the rotating block 20 to be manually rotated so that the rotating block 20 is perpendicular to the connecting shaft 17, thereby preventing the connecting shaft 17 from dislodging from the mounting hole 14. Since the axis of rotation of the rotating block 20 is not located at the center of the rotating block 20, the rotating block 20 can automatically maintain a vertical state under the action of gravity, and is not easily affected by vibration or other factors that cause it to automatically rotate to a horizontal state, thus affecting the stable installation of the isolation net 15.

[0036] In use, the conical block 8 is initially positioned at the top of the hollow cavity 4, and the two hanging ears 9 are suspended in the two placement slots 7 respectively. Before installing the isolation net 15, the installation position is determined. The worker places a base 1 and a column 2 on the ground to be installed, and threads the threaded ends of the two horizontal bars 11 into the threaded holes 10 of the two hanging ears. At this time, the worker manually grasps the two horizontal bars 11 to lift the conical block 8, causing the hanging ears 9 to disengage from the placement slots 7, and rotates the conical block 8 to make the hanging ears 9 slide along the horizontal section of the inverted L-shaped groove 6 to the vertical section. Then, the worker presses the horizontal bars 11 to make the conical block 8 descend along the hollow cavity 4 and the bottom end of the conical block 8 inserts into the ground until the hanging ears reach the ground. Stop when connecting the bottom of the L-shaped groove 6. Use the same operation to fix the other base 1 and column 2. After fixing, unfold the isolation net 15 and connect the connecting shafts 17 on both sides into the four mounting holes 14 respectively. Manually turn the rotating block 20 so that the rotating block 20 rotates around the groove 19 and finally becomes perpendicular to the connecting shaft 17. At this time, the installation of the isolation and protection device is completed. At this time, the connecting shaft 17 at the bottom is located above the conical block 8. Connect the power supply of the construction site to the warning light 3 through the wire so that the warning light 3 flashes. At this time, the workers can insert the vertical rod 13 into the through hole 12 as needed to hang tools. If not needed, the horizontal bar 11 can also be removed.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
