Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and in particular to a safety auxiliary device for road engineering maintenance construction. Background Technology

[0002] In road maintenance construction, various maintenance equipment is required depending on the maintenance area and project. During the maintenance process, the maintenance area and equipment need to be isolated and protected to ensure the safety of the equipment and external personnel.

[0003] Traditional isolation and protection methods involve erecting large-sized plate-like materials such as gratings around the outer ring of the maintenance area. These gratings are heavy and inconvenient to place. Furthermore, the lack of effective connections between the individual gratings makes them prone to shifting or even tipping over when subjected to external forces. Similarly, when it is necessary to adjust the angle between the gratings to enclose the maintenance area, gaps can easily appear between the gratings due to movement. This not only presents problems with movement but also makes it easy for foreign objects to enter the maintenance area through these gaps. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety auxiliary device for road engineering maintenance and construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A safety auxiliary device for road engineering maintenance and construction includes a fixed block and a rotating block. One end of the fixed block is fixedly connected to an end head, and a fan-shaped groove is opened on one side of the end head. A fixed rod is fixedly connected to the side of the fan-shaped groove close to the fixed block. A rotating block is rotatably connected inside the fan-shaped groove. An arc-shaped through groove that is slidably connected to the fixed rod is opened on the outer ring of the rotating block. A threaded hole is opened at the center of the top of the rotating block, and a circular slot is opened at the center of the bottom of the rotating block. It also includes a column, the bottom end of which is provided with a thread that matches the threaded hole.

[0006] Preferably, a step block is fixedly connected to the other end of the fixing block, and a first through hole is provided on one side of the step block.

[0007] Preferably, an installation strip is fixedly installed on the top of the fixing block, and the installation strip has several strip-shaped installation grooves.

[0008] Preferably, the top and bottom of the fan-shaped groove are symmetrically provided with second through holes, and a pin is movably connected in the second through hole.

[0009] Preferably, the rotating block of the inner ring of the arc-shaped through groove is provided with a plurality of third through holes, which are adapted to the pin.

[0010] Preferably, a stepped groove adapted to the stepped block is provided on the side of the top of the rotating block away from the arc-shaped through groove, and a fourth through hole corresponding to the first through hole is provided at the bottom of the stepped groove.

[0011] Preferably, a strip-shaped locking block is fixedly connected to the top of the column, and the locking block is adapted to the circular locking groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model incorporates rotating blocks and fixed blocks. The rotating blocks slide within a fan-shaped groove via an arc-shaped through-groove and a fixed rod, allowing for flexible adjustment of the angle between adjacent fixed blocks. This enables flexible adjustment of the protective range of the auxiliary device, which can be tailored to different needs at various construction sites. Furthermore, the two adjacent fixed blocks are easy to assemble, eliminating the need for moving the entire device like a traditional integrated protective wall. This design minimizes disruption to maintenance personnel and equipment. Once assembled, the overall safety auxiliary device is structurally sound, preventing tipping or displacement due to external forces and eliminating the risk of foreign objects entering the maintenance area due to large gaps.

[0013] This utility model features a column whose height can be selected according to the equipment that needs protection. The column can connect symmetrical fixing blocks and rotating blocks at the bottom and top, allowing a protective net to be installed between the fixing blocks at the top and bottom.

[0016] 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.

[0017] Reference Figure 1-5 A safety auxiliary device for road engineering maintenance and construction includes a fixed block 1 and a rotating block 11. One end of the fixed block 1 is fixedly connected to an end head 6. A fan-shaped groove 7 is opened on one side of the end head 6. A fixed rod 8 is fixedly connected to the side of the fan-shaped groove 7 close to the fixed block 1. The rotating block 11 is rotatably connected inside the fan-shaped groove 7. An arc-shaped through groove 12 that is slidably connected to the fixed rod 8 is opened on the outer ring of the rotating block 11. A threaded hole 14 is opened at the center of the top of the rotating block 11. A circular slot 17 is opened at the center of the bottom of the rotating block 11. It also includes a column 18, with a thread 19 at the bottom end that matches the threaded hole 14. The rotating block 11 rotates within the fan-shaped groove 7 by sliding with the fixed rod 8 through the arc-shaped through groove 12, allowing the angle between two adjacent fixed blocks 1 to be flexibly adjusted, thereby enabling flexible adjustment of the protection range of the auxiliary device. It can be adjusted according to different needs of different construction sites, and the splicing between two adjacent fixed blocks 1 is convenient, without the need to move the whole as a traditional integral protective wall, and it is less likely to hinder maintenance personnel and equipment. The height of the column 18 can be selected according to the equipment to be protected, etc. The height shown in the figure is only for illustration. The column 18 can connect the symmetrical fixed blocks 1 and rotating blocks 11 at the bottom and top, so that a protective net can be installed between the fixed blocks 1 at the top and bottom. Similarly, the installation method of the column 18 is simple and does not require the use of additional tools.

[0018] As a technical optimization of this utility model, a stepped block 2 is fixedly connected to the other end of the fixed block 1, and a first through hole 3 is provided on one side of the stepped block 2. The stepped block 2 facilitates the connection between the fixed block 1 and another adjacent rotating block 11, and the first through hole 3 is used for the insertion and fixing of the pin 10.

[0019] As a technical optimization of this utility model, an installation strip 4 is fixedly installed on the top of the fixing block 1, and several strip-shaped installation grooves 5 are opened on the installation strip 4. The installation grooves 5 are used to install the protective net with bolts. In actual use, the fixing blocks 1 at the top and bottom of the column 18 are installed symmetrically, that is, the installation strips 4 at the top and bottom correspond to each other, so that the protective net can be installed.

[0020] As a technical optimization of this utility model, the top and bottom of the fan-shaped groove 7 are symmetrically provided with second through holes 9, and a pin 10 is movably connected in the second through hole 9. The second through hole 9 and the pin 10 facilitate the fixing of the rotating block 11 after the angle is determined, so that the angle of the rotating block 11 is fixed and not affected by external forces.

[0021] As a technical optimization of this utility model, the rotating block 11 in the inner ring of the arc-shaped through groove 12 is provided with a plurality of third through holes 13, which are adapted to the pin 10. The third through holes 13 are used in conjunction with the second through holes 9, and the opening of multiple third through holes 13 allows the angle adjustment range of the rotating block 11 to meet various different construction areas.

[0022] As a technical optimization of this utility model, a stepped groove 15 adapted to the stepped block 2 is provided on the side of the top of the rotating block 11 away from the arc-shaped through groove 12, and a fourth through hole 16 corresponding to the first through hole 3 is provided at the bottom of the stepped groove 15. The stepped groove 15 and the stepped block 2 are used together to simplify the connection between the fixed block 1 and the rotating block 11 without the need for external tools.

[0023] As a technical optimization of this utility model, a strip-shaped locking block 20 is fixedly connected to the top of the column 18, and the locking block 20 is adapted to the circular locking groove 17. The locking block 20 is first inserted into the circular locking groove 17, and then the column 18 is rotated 90 degrees to make the locking block 20 lock in the circular locking groove 17, so that the rotating block 11 and the fixing block 1 at the top and bottom are relatively stable. Furthermore, since the bottom of the column 18 is connected to the threaded hole 14 through the thread 19, the stability of the column 18 itself is not affected during the 90-degree rotation, whether it is clockwise or counterclockwise.

[0024] In use, this invention first determines the safety protection area and shape based on the road maintenance construction area. Fixed blocks 1 are then placed on the ground within the determined area, followed by rotating blocks 11. A stepped block 2 at one end of one fixed block 1 is placed into a stepped groove 15 on one side of the rotating block 11 of another fixed block 1. A pin 10 is then inserted into the fourth through hole 16 and the first through hole 3, fixing the fixed block 1 and the adjacent rotating block 11. This process is repeated to assemble multiple fixed blocks 1 and rotating blocks 11. When the angle needs to be adjusted to enclose the protection area, one fixed block 1 is rotated to drive the adjacent rotating block 11 through the arc-shaped through groove 12 around the fixed rod 8 in the fan-shaped groove 7. After rotating to the desired angle, a pin 10 is inserted into the third through hole 13 and the second through hole 9, fixing the rotating block 1... 1. With the angle fixed, repeat the above operation. Finally, multiple sets of fixing blocks 1 and rotating blocks 11 can be spliced ​​together to form the required safety protection range. At this time, the column 18 can be connected into the threaded hole 14 through the thread 19 at the top of each rotating block 11. Then repeat the above operation to connect the circular slot 17 at the bottom of the rotating block 11 into the card block 20. Rotate the column 18 ninety degrees so that the card block 20 is locked inside the circular slot 17. The fixing block 1 at the top of the column 18 and the fixing block 1 at the bottom of the column 18 are symmetrically arranged, that is, the top and bottom mounting strips 4 correspond to each other. Then, the protective net located between the top and bottom fixing blocks 1 can be fixed in the mounting groove 5 with bolts to provide safety protection for the maintenance construction area. During the protection process, the pins 10 in the second through hole 9 and the third through hole 13 can also be pulled out to facilitate temporary adjustment of the angle of the protective net.

[0025] 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.
