Description

Technical Field

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

[0002] With the development of the times and the continuous construction and development of transportation, in order to facilitate the connection of roads on both sides of waters and valleys, or when roads need to pass through rivers, harbors, lakes, reservoirs, channels and other areas, in order to ensure smooth traffic, bridges need to be built. At the same time, prosperous urban areas sometimes also need to build elevated roads composed of viaducts. These are all highway bridges. When building highway bridges, in order to ensure the safety of the construction area and avoid irrelevant personnel entering the construction area, and at the same time avoid external interference in the construction area, it is often necessary to use protective devices to isolate the construction area to ensure the normal construction of the staff.

[0003] The height of existing guardrails is generally fixed, and the existing protective nets do not have the function of height adjustment. The construction machinery and tools at the construction site are at different heights, which poses a great safety hazard during the construction process. In addition, in different bridges or application scenarios, the adaptability is reduced, and the volume occupied by the transfer is large, which is not conducive to rapid transfer.

[0004] After searching, a temporary protective device for bridge construction with patent publication number CN220266330U was found. Although the device can solve the problems existing in the prior art, it still has certain disadvantages when used. The protective device is not easy to move during use, and it is also not easy to adjust the placement position, and the convenience of use is poor. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a protective device which can make the device more convenient to move, facilitate the adjustment of the placement position, and improve the convenience of use.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when in use, the universal wheel is initially in a suspended state, and the bottom of the triangular support supports the ground to ensure that the device is placed stably. When it is necessary to move or adjust the placement position, the transmission worm is rotated by turning the knob, so that the transmission worm drives the threaded collar to rotate through the engagement with the worm gear sleeve. Under the limit of the limit plate, the threaded collar drives the transmission support to slide downward along the guide hole, so that the transmission support pushes the bottom plate to move downward, and the bottom plate drives the universal wheel to move downward, so that the universal wheel gradually contacts the ground and supports the device.

When it is necessary to move or adjust the placement position, the transmission worm 10 is rotated by the knob 11, so that the transmission worm 10 drives the threaded collar 13 to rotate through the engagement with the worm gear sleeve 14. Under the limit of the limit plate 15, the threaded collar 13 drives the transmission support 7 to slide downward along the guide hole, so that the transmission support 7 pushes the bottom plate 8 to move downward, and the bottom plate 8 drives the universal wheel 9 to move downward, so that the universal wheel 9 gradually contacts with the ground and supports the device. When the bottom end of the limit plate 15 contacts the top end of the worm gear sleeve 14, the universal wheel 9 supports the triangular support 6, so that the triangular support 6 is suspended, and then the device can be pushed to move and adjust the placement position. After the position is adjusted, the universal wheel 9 is raised to be suspended, and the triangular support 6 supports the ground.
