Description

Technical Field

[0001] The utility model relates to the technical field of tower cranes, and in particular to a tower crane hook sound and light warning device with a protective function. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is also known as "tower crane". It is connected in length (height) section by section (referred to as "standard section") and is used to lift construction materials such as steel bars, wooden slats, concrete, and steel pipes. Tower crane is an indispensable equipment on construction sites. When the hook of the tower crane is used to hook construction materials, dangerous situations may occur. Therefore, when the tower crane is operating, workers or pedestrians cannot appear under the hook. However, because the tower crane workers are located at a higher place, they cannot warn the ground personnel. At the same time, in a complex construction environment, the ground workers cannot fully monitor the site, which may lead to unnecessary hazards.

[0003] The patent specification with announcement number CN217627306U discloses a tower crane hook sound and light alarm device. Through remote wireless remote control, the alarm start signal is sent to the alarm through the receiving module and the control module in sequence to turn on the alarm. This can effectively avoid the safety hazards caused by workers or pedestrians not paying attention to the construction of the tower crane hook and people being under the hook, thereby reducing the occurrence of accidents caused by building materials falling and hitting people during hook operation.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: when the tower crane hook of the above device is in use and unexpectedly shakes significantly, people outside are unable to promptly discover the shaking of the tower crane hook, and people outside are unable to avoid it in time, which may easily cause unexpected accidents. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a tower crane hook sound and light warning device with a protective function, which solves the problem in the related art that it is inconvenient to timely discover and warn the shaking of the tower crane hook.

[0006] The technical solution of the utility model is as follows:

[0007] A tower crane hook sound and light warning device with a protective function comprises a support platform, the upper end of the support platform is fixedly connected to a support block, the inner wall of the support block is movably connected to a rotating shaft, the inner wall of the support platform is fixedly connected to a connecting plate, and a hook assembly is movably arranged inside the support platform.

[0008] Preferably, the hook assembly comprises a vertical rod movably arranged inside the support platform, the vertical rod is located below the rotating shaft, and the upper end of the vertical rod is fixedly connected to a connecting chain.

[0009] Preferably, the upper end of the connecting chain is fixedly connected to the outer surface of the rotating shaft, and a disc is fixedly connected to the outer surface of the vertical rod.

[0010] Preferably, a transverse plate is fixedly connected to the outer surface of the circular disk, a first contact plate is arranged on one side of the transverse plate, and a stop plate is fixedly connected to the outer surface of the vertical rod.

[0011] Preferably, the stop plate is located below the disc, and the stop plate is located below the connecting plate.

[0012] Preferably, a hook is fixedly connected to the lower end of the vertical rod, and a reflective sheet is provided on one side of the hook.

[0013] Preferably, a warning flashing light is provided on the outer surface of the hook.

[0014] Preferably, the warning flashing light passes through the hook, vertical rod, disc and horizontal plate in sequence and is electrically connected to the first contact plate. Second contact plates are evenly arranged on the inner wall of the connecting plate, and the second contact plates correspond to the first contact plates through electrical connection.

[0015] The working principle and beneficial effects of the utility model are:

[0016] The utility model rotates the rotating shaft so that the connecting chain is coiled on the outer surface of the rotating shaft. At this time, the connecting chain will drive the vertical rod to move upward along the bracket platform until the stop plate of the vertical rod is moved to the bottom of the connecting plate, so that the stop plate touches the connecting plate. At this time, under the action of the connecting plate, the connecting plate blocks the stop plate from continuing to move over the connecting plate. Moreover, due to the existence of the connecting plate and the bracket platform, after the vertical rod is retracted and recovered, its hook cannot swing greatly inside the bracket platform, which reduces the swing amplitude of the hook and reduces the risk of its swing.

[0017] The utility model can drive the vertical rod to swing accordingly when the hook shakes unexpectedly, and the vertical rod drives the disc to swing at this time. When the hook swings greatly, the first contact plate of the disc touches the second contact plate of the connecting plate. When the first contact plate and the second contact plate are in contact with each other, the warning flashing light will be in an on state. At this time, the warning flashing light can operate normally, and the surroundings can be warned at this time, so that the outside world can quickly find that the hook is shaking, thereby solving the problem of inconvenience in timely finding and warning of the shaking of the tower crane hook.

[0018] The utility model enables the outside world to clearly discover the existence of the hook through the existence of the reflective sheet. When the hook shakes, the swing of the reflective sheet can form a swinging reflected light to the outside world, so that the outside world can more conveniently discover the hook.

DETAILED DESCRIPTION

[0024] The following will be combined with 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 of 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.

[0025] like Figure 1 As shown, this embodiment proposes a tower crane hook sound and light warning device with a protective function, including a support platform 1, a support block 2 is fixedly connected to the upper end of the support platform 1, a rotating shaft 3 is movably connected to the inner wall of the support block 2, a connecting plate 4 is fixedly connected to the inner wall of the support platform 1, and a hook assembly 5 is movably arranged inside the support platform 1.

[0026] like Figure 2As shown, the hook assembly 5 includes a vertical rod 51 movably arranged inside the bracket 1, the vertical rod 51 is located below the rotating shaft 3, the upper end of the vertical rod 51 is fixedly connected to a connecting chain 52, the upper end of the connecting chain 52 is fixedly connected to the outer surface of the rotating shaft 3, the outer surface of the vertical rod 51 is fixedly connected to a disk 53, the outer surface of the disk 53 is fixedly connected to a horizontal plate 531, one side of the horizontal plate 531 is provided with a first contact plate 5311, the outer surface of the vertical rod 51 is fixedly connected to a gear plate 54, the gear plate 54 is located below the disk 53, the gear plate 54 is located below the connecting plate 4, the A hook 55 is fixedly connected to the lower end of the vertical rod 51, and a reflective sheet 551 is provided on one side of the hook 55. A warning flashing light 552 is provided on the outer surface of the hook 55. The warning flashing light 552 passes through the hook 55, the vertical rod 51, the disc 53 and the horizontal plate 531 in sequence and is electrically connected to the first contact plate 5311. The warning flashing light 552 is used to provide sound reminders and early warnings to the surroundings, and the reflective sheet 551 is used to provide light stimulation and reminders to the outside world so that the outside world can quickly find the object. The existence of the connecting plate 4 and the stop plate 54 is used to prevent the vertical rod 51 from continuously moving inside the bracket 1.

[0027] like Figure 3 As shown, the inner wall of the connecting plate 4 is evenly provided with second contact plates 56 , and the second contact plates 56 correspond to the first contact plates 5311 through electrical connection. The existence of the first contact plates 5311 and the second contact plates 56 is used to control the operation of the warning flashing light 552 .

[0028] The working principle and use instructions of the utility model are as follows: when it is necessary to retract the hook 55, first the staff needs to rotate the rotating shaft 3 so that the connecting chain 52 is coiled on the outer surface of the rotating shaft 3. At this time, the connecting chain 52 will drive the vertical rod 51 to move upward along the bracket platform 1 until the stop plate 54 of the vertical rod 51 is moved to the bottom of the connecting plate 4, so that the stop plate 54 touches the connecting plate 4. At this time, under the action of the connecting plate 4, the connecting plate 4 blocks the stop plate 54 from continuing to move over the connecting plate 4. Due to the existence of the connecting plate 4 and the bracket platform 1, after the vertical rod 51 is retracted and recovered, its hook 55 cannot swing significantly inside the bracket platform 1, which reduces the swing amplitude of the hook 55 and reduces the risk of its swing. When the hook 55 swings unexpectedly, the hook 5 5 will drive the vertical rod 51 to swing accordingly, and the vertical rod 51 drives the disc 53 to swing. When the hook 55 swings greatly, the first contact plate 5311 of the disc 53 touches the second contact plate 56 of the connecting plate 4. When the first contact plate 5311 and the second contact plate 56 are in contact with each other, the warning flashing light 552 will be in an on state. At this time, the warning flashing light 552 can operate normally, and an early warning reminder can be given to the surroundings, so that the outside world can quickly find that the hook 55 is shaking, and due to the existence of the reflective sheet 551, the outside world can obviously find the existence of the hook 55. When the hook 55 shakes, the swing of the reflective sheet 551 can form a swinging reflected light to the outside world, so that the outside world can find the hook 55 more conveniently.
