Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a protection device. Background Art

[0002] Construction engineering refers to a systematic project covering the whole process of design, construction, management and maintenance of buildings or infrastructures. It includes various links from preliminary planning, detailed design to construction implementation, quality control, acceptance and post-maintenance. The goal of construction engineering is to create buildings or infrastructures that meet functional requirements, safety codes, aesthetic requirements and economic benefits.

[0003] For example, the Chinese utility model patent (CN221502925U) discloses a protection device for construction engineering, which records: "It can adjust the angle of the guardrail so that the guardrail can cope with strong wind weather and meet the required shielding effect." It also records the technical problem: "In the traditional protection device for construction engineering, the shielding function of the protection device is often realized through the guardrail. In this way, if the guardrail is too thick, it is difficult to cope with strong wind weather, and if the guardrail is too thin, the shielding effect will be affected."

[0004] To sum up, it can be seen that in the prior art, wheels are arranged on a fixed base to support the fixed base, and then the position of the device is restricted by the friction force between the wheels and the ground. However, this method has the following technical problems: During the actual use of the device, only relying on the friction between the wheels and the ground to restrict the position of the device, it is easy for the position of the device to change under the influence of wind force or being pushed by pedestrians, thus reducing the stability of the device. Therefore, this application proposes a protection device to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Utility Model

[0005] Based on this, in view of the above technical problems, it is necessary to provide a protection device. By unfolding the rotating rod, the bottom of the rotating block is in close contact with the ground through the ground-breaking cone. Through multiple rotating blocks being in contact with the ground, the overall contact area between the device and the ground is increased, thereby dispersing the external force applied to the enclosure, thus improving its stability, reducing the risk of the enclosure being pushed or tilted, and further improving the overall stability of the device. After the device is used up, the rotating rod can also be retracted into the U-shaped frame. Relying on the mutual adsorption of the first magnet and the second magnet, the rotating rod is kept inside the U-shaped frame, reducing the space occupied by the device when it is idle. In addition, the protection plate can isolate the ground-breaking cone from the outside, thereby reducing the situation where the tip of the ground-breaking cone causes damage to operators or other items during the transportation of the device, and improving the practicability of the device.

[0006] To solve the above technical problems, the present utility model adopts the following technical solutions:

[0007] A protective device, which is applied to construction projects.

[0008] The protective device specifically includes:

[0009] A device base, on the inner wall of the device base and near the left and right sides respectively, there are slidingly connected fixed cones.

A protection plate is slidably connected between the two fixed rails. A limiting hole is opened on the protection plate. The inner walls of the two fixed rails are respectively threadedly connected with limiting bolts, and the limiting bolts are inserted into the limiting holes.

[0013] As a preferred embodiment of the protective device provided by the present utility model, the blocking mechanism includes a mounting block, an insertion hole, a pressing component, and a limiting component.

Springs are respectively fixedly connected to the inner wall of the blocking rod and located on the upper and lower sides.

Through the fitting of multiple rotating blocks with the ground, the overall contact area of the device with the ground is increased, thereby dispersing the external force applied to the enclosure, improving its stability, reducing the risk of the enclosure being pushed or tilted, and thus enhancing the overall stability of the device. After the device is used up, the rotating rod can be retracted into the U-shaped frame. Relying on the mutual adsorption of the first magnet and the second magnet, the rotating rod is kept inside the U-shaped frame, reducing the space occupied by the device when it is idle.

[0027] In order to enable those skilled in the art of this technology to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of this utility model.

[0028] As described in the background art, however, during the actual use of this device, only relying on the friction between the wheels and the ground to limit the position of the device, it is easy for the position of the device to change under the influence of wind or being pushed by pedestrians, thereby reducing the stability of the device.

[0029] To solve this technical problem, this utility model provides a protection device, which is applied to construction projects.

[0030] Specifically, please refer to Figure 1 - Figure 2 , the protection device specifically includes:

[0031] A device base 1, on the inner wall of the device base 1 and near the left and right sides respectively, there are sliding connections with fixed cones 2. The top of the device base 1 is detachably connected with a U-shaped frame 3 by bolts. There are multiple support mechanisms 4 arranged on the U-shaped frame 3, and multiple blocking mechanisms 5 are arranged on the device base 1;

[0032] The support mechanism 4 includes a rotating rod 6, a fixed rail 11, a support assembly, and a protection assembly. The inner wall of the U-shaped frame 3 is rotatably connected with a rotating rod 6, and two fixed rails 11 are fixedly connected to the outer wall of the U-shaped frame 3.

[0033] The protective device provided by the utility model unfolds the rotating rod 6, so that the bottom of the rotating block 7 is in close contact with the ground through the ground-breaking cone 8. By fitting multiple rotating blocks 7 to the ground, the overall contact area of the device with the ground is increased, thereby dispersing the external force applied to the enclosure, improving its stability, reducing the risk of the enclosure being pushed or tilted, and thus improving the overall stability of the device. After the device is used, the rotating rod 6 can also be retracted into the U-shaped frame 3. Relying on the mutual adsorption of the first magnet 9 and the second magnet 10, the rotating rod 6 is kept inside the U-shaped frame 3, reducing the space occupied by the device when it is idle. In addition, the protection plate 12 can isolate the ground-breaking cone 8 from the outside, thereby reducing the damage to the operator or other items caused by the sharp tip of the ground-breaking cone 8 during the transportation of the device, and improving the practicability of the device.

[0034] In order to enable the personnel in the technical field to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings.

[0035] Embodiment 1:

[0036] Please refer to Figure 2 - Figure 4 , a protective device, which includes:

[0037] The support assembly includes a rotating block 7. One end of the rotating rod 6 away from the U-shaped frame 3 is rotatably connected to the rotating block 7. A plurality of ground-breaking cones 8 are fixedly connected to the bottom of the rotating block 7. A first magnet 9 is fixedly connected to the inner wall of the rotating block 7. A second magnet 10 adapted to the first magnet 9 is fixedly connected to the inner wall of the U-shaped frame 3. The first magnet 9 and the second magnet 10 can adsorb each other, thereby restricting the rotating block 7 retracted into the U-shaped frame 3.

[0038] The protection assembly includes a protection plate 12. The protection plate 12 is slidably connected between two fixed rails 11. A limiting hole 13 is formed in the protection plate 12. Limiting bolts 14 are respectively threadedly connected to the inner walls of the two fixed rails 11. The limiting bolts 14 are inserted into the limiting hole 13. The position of the protection plate 12 can be restricted through the limiting hole 13 and the limiting bolts 14, thereby using the protection plate 12 to prevent the rotating block 7 from leaving the U-shaped frame 3 and at the same time preventing the ground-breaking cone 8 on the rotating block 7 from accidentally damaging the operator during the transfer or installation of the device.

[0039] Through the above structural design, after moving the device to the designated position, drive the two fixing cones 2 into the ground, and loosen the limiting bolt 14 so that the limiting bolt 14 moves away from the limiting hole 13, thereby releasing the position limitation of the protection plate 12. Then, pull up the protection plate 12, and then unfold the rotating rod 6 so that the bottom of the rotating block 7 is in close contact with the ground through the soil-breaking cone 8. Operate each support mechanism 4 one by one to fix the device. After the device is used up, lift up the protection plate 12, rotate the rotating rod 6, retract the rotating rod 6 into the U-shaped frame 3, and rotate the rotating block 7 to the vertical state. Rely on the mutual adsorption of the first magnet 9 and the second magnet 10 to keep the rotating rod 6 inside the U-shaped frame 3. Then release the protection plate 12 so that the protection plate 12 slides down between the two fixed rails 11 under the action of gravity. Then adjust the position of the protection plate 12 so that the limiting hole 13 is aligned with the limiting bolt 14, and then tighten the limiting bolt 14 so that the limiting bolt 14 is inserted into the limiting hole 13, thereby restricting the position of the protection plate 12. Then pull out the fixing cone 2 to complete the removal of the device.

[0040] Embodiment 2:

[0041] Further optimize the protection device provided in Embodiment 1. Specifically, as Figure 5 shown, the blocking mechanism 5 includes a mounting block 15, a jack 16, a pressing component, and a limiting component. Mounting blocks 15 are fixedly connected to the top of the device base 1 and the bottom of the U-shaped frame 3 respectively. A jack 16 is formed on the mounting block 15, and the jack 16 is adapted to the insertion rod 21.

[0042] The pressing component includes a blocking rod 17. Springs 18 are fixedly connected to the inner walls of the upper and lower sides of the blocking rod 17 respectively. One end of each of the two springs 18 away from each other is fixedly connected to a connecting plate 19. The two connecting plates 19 are both slidably connected to the inner wall of the blocking rod 17. Extrusion blocks 20 are fixedly connected to the outer walls of the two connecting plates 19. The extrusion blocks 20 are slidably connected to the inner wall of the blocking rod 17. The springs 18 can make the insertion rod 21 stably inserted into the corresponding jack 16 when the extrusion block 20 is not subjected to external force.

[0043] The limiting component includes an insertion rod 21. Insertion rods 21 are fixedly connected to the sides of the two connecting plates 19 away from each other. The insertion rods 21 are slidably connected to the inner wall of the blocking rod 17, and the insertion rods 21 are inserted into the jacks 16.

[0044] Through the above structural design, by squeezing the two extrusion blocks 20 towards the middle, the two connecting plates 19 can be driven to approach each other, the two springs 18 can be deformed, and the two insertion rods 21 can slide into the inside of the blocking rod 17, so that the insertion rods 21 leave the corresponding insertion holes 16, and the blocking rod 17 can be separated from the device, and the damaged blocking rod 17 can be replaced. Squeeze the two extrusion blocks 20 of the new blocking rod 17 towards the middle until the insertion rods 21 are retracted into the blocking rod 17, then align the blocking rod 17 and place it between the two mounting blocks 15, and then release the two extrusion blocks 20, and the insertion rods 21 can be inserted into the insertion holes 16 under the action of the elastic force of the springs 18, thus completing the installation of the blocking rod 17.
