Description

Technical Field

[0001] The utility model belongs to the technical field of building safety warnings, in particular to a warning device for building safety production. Background Art

[0002] Warning devices for safe production generally serve as warnings, reminding people that there are special circumstances here or ahead, so that passing pedestrians and vehicles can drive carefully or take a detour. At present, when construction is being implemented on a construction site, there must be warning devices around to issue warnings. The base of general warning signs or warning devices is mostly a whole flat plate. Although the warning sign with this base can maintain overall stability, the ground of the construction site is generally not flat, and it may also be uneven. At this time, a warning sign or warning device that can adapt to the uneven ground is needed.

[0003] At the same time, the patent specification with the announcement number CN 220666022 U discloses

[0004] A warning device for construction safety production includes a base, a movable wheel is fixedly installed on the bottom of the base, and a positioning screw is sleeved on the internal thread of the base, the top of the base is fixedly connected to a support box, the side of the inner cavity of the support box is fixedly connected to a support plate, and the top of the support plate is rotatably connected to a rotating screw.

[0005] However, in the implementation of relevant technologies, it was found that the above-mentioned warning device for construction safety has the following problems: the warning device is mostly used in construction sites, but the ground of the construction site is not all flat and unobstructed, and the uneven ground still accounts for the majority. The device can remain stable on the flat ground and will not tilt or fall to the ground, but it is difficult to maintain balance on the uneven ground, and manual leveling is required. However, manual leveling cannot ensure the balance of the device like the real ground. If the warning device falls to the ground, pedestrians and vehicles are likely to mistakenly enter the danger zone.

[0006] Therefore, in view of the above problems, a warning device for construction safety production is proposed. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the ground is relatively flat, the base 2 is used, the position of the device can be freely moved by the moving wheel 3, and the bottom plate 7 is pushed downward by the first motor 4, and finally the bottom plate 7 is fitted with the bottom surface, thereby supporting the device as a whole. This supporting structure is suitable for places with relatively flat ground, and can prevent the warning device from tilting or falling to the ground.

[0025] Specifically, a second motor 17 is fixedly installed on the inner top of the central axis 1, a rotating shaft 15 is fixedly installed on the main shaft end of the second motor 17, and the rotating shaft 15 is slidingly connected to the central axis 1. The second motor 17 is used to drive the rotating shaft 15 to start rotating, and the second motor 17 is a power source.

[0026] Furthermore, a bearing 16 is rotatably provided on the outer side of the bottom of the rotating shaft 15, and the bearing 16 is fixedly connected to the central shaft 1. At the same time, the bearing 16 is used to support the rotation of the rotating shaft 15, reduce the friction coefficient during its movement, and ensure its rotation accuracy, thereby extending its service life.

[0027] Furthermore, a solar panel 18 is fixedly connected to the top surface of the rotating shaft 15, and a display screen 14 is threadedly connected to the outer side of the rotating shaft 15. The display screen 14 is used to write warning slogans. At the same time, the solar panel 18 provides electricity for the display screen 14, which can save some energy.

[0028] It is worth mentioning that an adjustment sleeve 9 is slidably provided on the outer side of the central axis 1, and a lock is fixedly provided on the outer side of the adjustment sleeve 9. By sliding the adjustment sleeve 9 up and down, the height of the warning device can be adjusted to cope with the situation of insufficient height, and finally the position of the adjustment sleeve 9 is fixed by the lock.

[0029] It is worth noting that a fixed shaft 10 is rotatably provided inside the adjusting sleeve 9, and an adjusting shaft 11 is slidably provided outside the fixed shaft 10.

[0031] Among them, the first motor 4 and the second motor 17 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" viewing angles of this device are based on the direction shown in the figure.

[0032] Working principle and process:

[0033] Before using a warning device for construction safety production, first select different support components at the bottom of the central axis 1 according to the ground conditions, replace the base 2 when the ground is relatively flat, and when the device is moved to the specified position by the moving wheel 3, turn on the switch of the first motor 4, the first motor 4 drives the main gear 5 to rotate, and the main gear 5 drives the sub-gear 6 to rotate. A thread is provided inside the sub-gear 6, and a threaded column is also provided on the top surface of the bottom plate 7. When the sub-gear 6 rotates, it just pushes the bottom plate 7 to move downward, and finally the bottom plate 7 supports the ground to prevent the moving wheel 3 from sliding. The support plate 8 here is used to support the main gear 5 and the sub-gear 6 to prevent them from falling. When the ground is uneven, replace the tripod support device. After replacing the support component, the angle of the fixed shaft 10 and the length of the adjustment shaft 11 can be adjusted to help the device level. After leveling, the adjustment shaft 11 is locked by the knob 13, and then the pointed foot 12 is inserted into the soil. In the embodiment, due to the uneven ground, if the height is not enough after leveling, the height can be increased by adjusting the adjustment sleeve 9 up and down. After the bottom of the device is fixed, the display screen 14 can be opened. The display screen 14 can be used to write warning slogans. Energy is supplemented by the solar panel 18, and then the switch of the second motor 17 is turned on. The second motor 17 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the display screen 14 to rotate at the same time, so that people passing by can see the warning slogans. The function of the bearing 16 is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy, thereby extending its service life. The device can adapt to different ground conditions by flexibly replacing the supporting components. Whether it is on some flat ground or some uneven ground, it can maintain balance, thereby avoiding the warning device from cutting obliquely or falling on the ground, causing pedestrians or vehicles to mistakenly enter the dangerous area due to loss of warning.
