Technical Field

[0001] This utility model relates to the field of highway survey and protection technology, specifically to a mobile protection device for highway survey. Background Technology

[0002] Highway surveying is a crucial preliminary step in highway construction. Its purpose is to comprehensively collect data on the natural, geographical, and geological aspects related to the highway route, providing a reliable basis for subsequent design and construction. Protective devices are used during highway surveying because numerous safety hazards exist at the survey site, necessitating the protection of survey personnel, pedestrians, and vehicles. Currently used protective devices include guardrails, protective tapes, and warning tapes, used for protection and warning pedestrians and vehicles. For example, while protective tapes and warning tapes are easy to fold and store, when unfolded for use, due to different usage scenarios and needs, they need to be bent and wrapped around the survey location. Therefore, corresponding positioning support rods and support frames are required. The disassembly, assembly, and storage of these support rods and frames can be relatively inconvenient, affecting the efficiency of setting up and moving the protective devices.

[0003] In view of this, we propose a mobile protective device for highway surveying. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a mobile protective device for highway surveying, which can effectively solve the problem that the support frame support rod for positioning the protective tape and warning tape is inconvenient to disassemble and store, affecting the efficiency of the construction and movement of the protective device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a mobile protective device for highway surveying, including a mobile box and a take-up roller rotatably connected to the bottom of the inner cavity of the mobile box. A protective warning tape is fixedly connected to the surface of the take-up roller, and one end of the protective warning tape moves through the mobile box and is fixedly connected to a mobile column.

[0007] Among them, the movable box is provided with a fixing component for clamping the movable column on the side near the movable column;

[0008] The mobile container is equipped with a positioning component for positioning the protective warning tape.

[0009] Furthermore, the fixing component includes a U-shaped fixing block fixedly connected to the side of the movable box near the movable column, and a U-shaped movable block is provided on one side of the U-shaped fixing block, with one side of the U-shaped movable block slidably connected to the surface of the movable box.

[0010] Furthermore, a lead screw is threadedly connected to the inner wall of the U-shaped movable block. One end of the lead screw is rotatably connected to the surface of the movable box, and the other end of the lead screw rotates through the movable box and is fixedly connected to a knob.

[0011] Furthermore, the positioning component includes a U-shaped frame fixedly connected to one side of the movable box, with multiple sets of U-shaped positioning rods inserted into the inner wall of the U-shaped frame, and screws fixedly connected to the bottom of the U-shaped positioning rods.

[0012] Furthermore, the positioning component also includes a storage box fixedly connected to one side of the moving box. The storage box contains multiple sets of counterweights, and the top of the counterweights has a threaded hole that mates with the screw thread.

[0013] Furthermore, the top of the take-up roller rotates through the moving box and is fixedly connected to a handwheel.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] A mobile protective device for highway surveying includes a mobile box 1 and a take-up roller 15 rotatably connected to the bottom of the inner cavity of the mobile box 1. A protective warning tape 3 is fixedly connected to the surface of the take-up roller 15. One end of the protective warning tape 3 passes through the mobile box 1 and is fixedly connected to a mobile post 4. A fixing component for clamping the mobile post 4 is provided on the side of the mobile box 1 near the mobile post 4. A positioning component for positioning the protective warning tape 3 is provided on the mobile box 1. A handwheel 2 is fixedly connected to the top of the take-up roller 15, which rotates through the mobile box 1.

[0025] Specifically, rotating the handwheel 2 drives the take-up roller 15 to rotate and pulls the moving column 4, which facilitates the unfolding and retraction of the protective warning tape 3. At the same time, the moving column 4 and the positioning component are used to position and support the protective warning tape 3 when unfolding, and the fixing component clamps the protective warning tape 3 to prevent the take-up roller 15 from rotating under the influence of external factors when unfolding and using, which would cause the protective warning tape 3 to loosen. When the protective warning tape 3 is retracted, the positioning component can be disassembled and placed on the mobile box 1. The fixing component can clamp and fix the moving column 4, integrating the whole and making it easy to move.

[0026] Specifically, the fixing component includes a U-shaped fixing block 9 fixedly connected to the side of the movable box 1 near the movable column 4, a U-shaped movable block 10 provided on one side of the U-shaped fixing block 9, a side of the U-shaped movable block 10 slidably connected to the surface of the movable box 1, a screw rod 11 threadedly connected to the inner cavity side wall of the U-shaped movable block 10, one end of the screw rod 11 rotatably connected to the surface of the movable box 1, and one end of the screw rod 11 rotatably passes through the movable box 1 and is fixedly connected to a knob 12. The positioning component includes a U-shaped frame 6 fixedly connected to one side of the movable box 1, multiple sets of U-shaped positioning rods 7 inserted into the inner wall of the U-shaped frame 6, a screw rod 13 fixedly connected to the bottom of the U-shaped positioning rod 7. The positioning component also includes a storage box 5 fixedly connected to one side of the movable box 1, multiple sets of counterweights 8 placed inside the storage box 5, and a threaded hole 14 with threaded engagement with the screw rod 13 on the top of the counterweights 8.

[0027] Specifically, when the protective warning tape 3 is unfolded and used, it can be bent according to the survey scene and needs to surround and protect the survey location. At the bending point, the U-shaped positioning rod 7 is inserted into the protective warning tape 3. The counterweight jar 8 is then tightened to the bottom of the U-shaped positioning rod 7 by engaging the screw 13 at the bottom of the U-shaped positioning rod 7 with the threaded hole 14 on the counterweight jar 8. Water or sand can be filled into the counterweight jar 8 to improve the stability of the U-shaped positioning rod 7. Conversely, when disassembly is required, the counterweight jar 8 can be removed from the U-shaped positioning rod 7. Unscrew the U-shaped positioning rod 7 and pour out the counterweight material. At the same time, pull the U-shaped positioning rod 7 off the protective warning tape 3. Then, place the counterweight pot 8 into the storage box 5 and insert the U-shaped positioning rod 7 into the U-shaped frame 6 for easy storage and carrying of the counterweight pot 8 and the U-shaped positioning rod 7. After the protective warning tape 3 is completely retracted into the movable box 1, the movable column 4 can be tightly attached to the U-shaped fixing block 9. Then, by rotating the knob 12, the U-shaped movable block 10 can be moved by rotating the screw 11 to clamp and fix the movable column 4, thereby facilitating the overall movement.

[0028] The working principle of this utility model is as follows: During use, rotating the handwheel 2 drives the take-up roller 15 to rotate. The rotation of the take-up roller 15 unfolds the protective warning tape 3 wrapped around its surface. Simultaneously, the moving column 4 is pulled. One end of the protective warning tape 3 is fixed to the take-up roller 15, and the other end is connected to the moving column 4. As the take-up roller 15 rotates and the moving column 4 is pulled, the protective warning tape 3 gradually extends to the required length. After completing the survey work, rotating the handwheel 2 in the opposite direction causes the take-up roller 15 to rotate in the opposite direction, rewinding the protective warning tape 3. When the protective warning tape 3 is unfolded to surround the survey location, depending on the actual scene and needs, the U-shaped positioning rod 7 is taken out from the U-shaped frame 6 and inserted into the corresponding position of the protective warning tape 3 at the bending point. The screw 13 fixedly connected to the bottom of the U-shaped positioning rod 7 then functions, allowing the counterweight jar 8 to be taken out of the storage box 5. The counterweight jar 8 is then screwed onto the U-shaped frame 6 through the threaded hole 14 at its top, which engages with the screw 13. At the bottom of the positioning rod 7, water or sand can be filled into the counterweight container 8 to increase the overall weight and improve the stability of the U-shaped positioning rod 7. This ensures reliable positioning and support for the protective warning tape 3, keeping it stable and preventing displacement during use. When the protective warning tape 3 is fully retracted into the movable box 1, the moving column 4 will approach and adhere to the U-shaped fixing block 9. At this time, rotating the knob 12 will drive the lead screw 11 to rotate. Since the lead screw 11 is threadedly connected to the inner cavity side wall of the U-shaped movable block 10, and one side of the U-shaped movable block 10 is slidably connected to the surface of the movable box 1, the rotation of the lead screw 11 will drive the U-shaped movable block 10 to move towards or away from the U-shaped fixing block 9 until the U-shaped movable block 10 clamps and fixes the moving column 4. In this way, the protective warning tape 3, the moving column 4, and other components are stably fixed on the movable box 1, facilitating overall movement and transportation, and improving the mobility and efficiency of the protective device during surveying work.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
