Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to an early warning device for edge protection in building construction. Background Technique

[0002] Building construction is a production activity in which people use various building materials and mechanical equipment to build various building products according to specific design requirements within a certain space and time. During the building construction process, some dangerous operations will be carried out. To ensure the safety of construction workers, guardrails must be installed around the operation platform and pedestrian passage, whether it is above or below the ground, around the operation platform, around the pedestrian passage, around the foundation pit, and around the structure to protect the safety of the operation population or pedestrians.

[0003] After retrieval, a warning device for edge protection in building construction disclosed in a Chinese patent with the publication number CN220522085U has the following technical key points: 1. Since the sizes of the protection plates are fixed, due to different construction site conditions, the required heights of the protection plates for protection are different, resulting in poor protection effects; 2. The protection plates and warning lights are fixedly arranged, and it is inconvenient to disassemble and repair the warning lights after they are damaged; 3. Since the ground at the construction site is not necessarily flat, when setting the protection plates, the position of the bottom plate under the protection plates cannot be adjusted, resulting in unstable installation of the protection plates. However, due to the vertical fixing method of this device, when the warning device is collided by equipment or vehicles, the middle part of the warning device will break, causing more serious damage to the equipment. Moreover, when the warning device is tilted, its sensing device will lose the sensing target and stop alarming, and the accident site fails to continuously issue an alarm, making it difficult for the staff to obtain the news of the accident in time, thus expanding the damage and impact caused by the accident.

[0004] Therefore, a new solution is needed to solve this problem. Content of the Utility Model

[0005] Aiming at the problems in the above background technique that the existing technology has the problems that vertical fixing easily causes the equipment to break, resulting in more serious damage to the equipment, and the warning device loses the sensing target and cannot continuously alarm when it is tilted, thus expanding the damage and impact caused by the accident.

[0006] An early warning device for edge protection in building construction disclosed by the utility model includes a protective shell. Both side surfaces of the protective shell are fixedly connected with connecting plates. A sliding column is inserted into the interior of the protective shell, and the outer surface of the sliding column is inserted into each connecting plate. A spring is installed on the outer surface of the sliding column. A fixed disk one and a fixed disk two are respectively arranged on both side surfaces of the protective shell. A plug is fixedly connected to one end of the sliding column close to the fixed disk two. One side surface of the plug close to the protective shell is fixedly connected with the spring, and one end of the spring away from the plug is fixedly connected with the fixed disk two. Card slots are opened in the interiors of the fixed disk one and the fixed disk two, and the inner walls of each card slot are rotationally connected with the corresponding connecting plate. A sliding slot one is opened in the interior of the fixed disk one, a slot is opened in the interior of the sliding slot one, and a push-button switch is installed in the slot.

[0007] By adopting the above scheme, when using this device, when the protective shell contacts the equipment, the protective shell will drive the connecting plate to rotate in the card slot under force. When the connecting plate rotates, it will drive the sliding column to rotate, so that the sliding column slides in the sliding slot one of the fixed disk one. When the sliding column moves along the sliding slot one to the slot, the elastic force of the spring will push the sliding column to move leftward into the slot to trigger the push-button switch. The push-button switch will control the alarm lamp two and the sound amplifying device to give an alarm, so that the device can still start early warning when the early warning device does not pass through the infrared induction area. The push-button switch can also be installed on the upper part of the sliding slot one. Installing it on the upper part can be set to the effect that the connecting plate drives the sliding column to disengage from the push-button switch to start early warning.

[0008] Optionally, a connecting column is fixedly connected to one side surface of each connecting plate away from the protective shell. Sliding slots two are opened in the interiors of the fixed disk one and the fixed disk two, and the inner walls of each sliding slot two are slidably connected with the corresponding connecting column.

[0009] By adopting the above scheme, the sliding slots two opened can facilitate the connection between the fixed disk one and the fixed disk two and the connecting column. The connection between the connecting column and the fixed disk one and the fixed disk two can increase the stability of the protective shell when rotating.

[0010] Furthermore, fixing plates are fixedly connected to the outer surfaces of the fixed disk one and the fixed disk two, and equally spaced fixing bolts are threadedly connected to the interior of each fixing plate.

[0011] By adopting the above scheme, the fixing plates provided can facilitate the fixation of the fixed disk one and the fixed disk two, and the bolts provided can facilitate the fixation of the fixing plates.

[0012] Furthermore, a sliding slot three is opened in the interior of the fixed disk two, and the inner wall of the sliding slot three is in contact with the sliding column.

[0013] By adopting the above solution, the sliding column can be conveniently limited by opening the third sliding groove. Through the contact between the third sliding groove and the sliding column, not only can the sliding column rotate in the second fixed disk, but also the left-right lateral movement of the sliding column is not affected.

[0014] Furthermore, two rubber pads are fixedly installed inside each of the first fixed disk and the second fixed disk, and each rubber pad is in contact with the outer surface of the corresponding connecting plate.

[0015] By adopting the above solution, the two rubber pads can be used as a simple brake. Through the contact and friction between the rubber pad and the connecting plate, the protection shell is prevented from driving the connecting plate to rotate due to inertia and gravity.

[0016] Furthermore, an infrared sensing area and a sound amplifying device are installed inside the protection shell, and explosion-proof toughened glass should be installed in front of the infrared sensing area.

[0017] By adopting the above solution, the infrared sensing area can sense the equipment approaching the warning device, and the explosion-proof toughened glass can provide anti-collision protection for the infrared sensing area.

[0018] Furthermore, an alarm lamp 1 and an alarm lamp 2 are installed above the protection shell, and anti-collision fences are installed outside both the alarm lamp 1 and the alarm lamp 2.

[0019] By adopting the above solution, when the infrared sensing area senses the equipment, the alarm lamp 1 and the sound amplifying device will be activated to issue a warning. When the sliding column triggers the push-button switch, the alarm lamp 2 and the sound amplifying device will be activated to issue a warning. The anti-collision fences can provide anti-collision protection for the alarm lamp 1 and the alarm lamp 2.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] 1. By setting devices such as connecting plates, sliding columns, springs, and slots, when using this device, when the protection shell comes into contact with the equipment, the protection shell will be stressed to drive the connecting plate to rotate in the card slot. When the connecting plate rotates, it will drive the sliding column to rotate, causing the sliding column to slide in the first sliding groove of the first fixed disk. When the sliding column moves along the first sliding groove to the slot, the elastic force of the spring will push the sliding column to move leftward into the slot to trigger the push-button switch, and the push-button switch will control the alarm lamp 2 and the sound amplifying device to issue an alarm, so that the device can still start the warning when the warning device does not pass through the infrared sensing area.

[0022] 2. The utility model is provided with components such as a connecting plate, a connecting column, a first fixing plate and a second fixing plate. When using the device, when the protective shell contacts the device, the protective shell will rotate around the connecting plate under the thrust of the device, and the connecting plate and the connecting column will rotate in the first fixing plate and the second fixing plate. Through the angle change of the protective shell, the device can avoid damage to the equipment caused by the impact on the warning device. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the first fixed disk 6 and the second fixed disk 7 are respectively provided on both side surfaces of the protective shell 1. By providing the first fixed disk 6 and the second fixed disk 7, it is convenient to fix the connecting plate 2 and the protective shell 1. A plug 8 is fixedly connected to one end of the sliding column 4 close to the second fixed disk 7. By providing the plug 8, it is convenient to install the spring 5. One side surface of the plug 8 close to the protective shell 1 is fixedly connected to the spring 5, and the end of the spring 5 away from the plug 8 is fixedly connected to the second fixed disk 7. Slots 20 are respectively opened in the interiors of the first fixed disk 6 and the second fixed disk 7. By opening the slots 20, it is convenient for the first fixed disk 6 and the second fixed disk 7 to be rotatably connected. The inner wall of each slot 20 is rotatably connected to the corresponding connecting plate 2. A first sliding groove 10 is opened in the interior of the first fixed disk 6. By opening the first sliding groove 10, it is convenient for the sliding column 4 to move in the first fixed disk 6. A slot 11 is opened in the interior of the first sliding groove 10.

By moving the sliding column 4 into the interior of the slot 11, the push-button switch is pressed, and the push-button switch will activate the second alarm lamp 18 and the sound amplification device 16, so that when the early warning device is tilted and the infrared sensing area 15 is not triggered, an alarm is given.

[0032] Please refer to Figure 3 and Figure 4 , A connecting column 3 is fixedly connected to one side surface of each connecting plate 2 away from the protective shell 1. By providing the connecting column 3, it is convenient to connect the connecting plate 2 with the first fixed disk 6 and the second fixed disk 7. Second sliding grooves 9 are respectively opened in the interiors of the first fixed disk 6 and the second fixed disk 7. By opening the second sliding grooves 9, it is convenient to connect with the connecting column 3. The inner wall of each second sliding groove 9 is slidably connected to the corresponding connecting column 3. By connecting the connecting column 3 with the second sliding groove 9, the stability of the protective shell 1 during rotation can be increased.

[0033] In a preferred embodiment, a sliding groove III 13 is formed inside the fixed disk II 7.
