Description

Technical Field

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

[0002] Construction is a production activity in which people use various building materials and mechanical equipment to build various building products in a certain space and time according to specific design requirements. In the process of construction, some dangerous operations will be carried out. In order to ensure the safety of construction workers, early warning devices must be installed around the foundation pit and the structure.

[0003] At present, traditional early warning devices usually use ground anchors as the main fixing method. The basic principle of this method is to embed the ground anchor deep into the ground and provide the necessary support and stability for the early warning device through the friction and gravity between the ground anchor and the soil. However, in the complex and changeable construction site environment, the flatness of the ground is often difficult to guarantee, and the uneven road surface may become an obstacle to the installation of the ground anchor. When the ground anchor tries to find a support point on such a ground, it is often difficult to find a suitable insertion position due to the irregularity of the terrain. After all, traditional ground anchors are mostly fixed to the early warning device by welding. Although this connection method guarantees the connection strength between the two to a certain extent, when installed on an uneven road surface, it may cause the bottom of the device to float. When there are obvious ups and downs or potholes on the ground, the ground anchor may not be fully embedded in the ground, resulting in the connection between it and the early warning device being suspended or semi-suspended. The appearance of the floating state will greatly reduce the stability of the early warning device. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides an early warning device for edge protection in building construction through improvement. The technical solution of the present invention is:

[0028] Embodiment 1:

[0029] like Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, an early warning device for edge protection in construction includes a base 1, a guardrail 2 is fixedly connected to the top of the base 1, an adjustment mechanism is arranged inside the base 1, the adjustment mechanism includes a connecting plate 3 arranged in the base 1, a spring 4 is fixedly connected to the bottom end of the connecting plate 3, a movable plate 5 is fixedly connected to the bottom end of the spring 4, a ground anchor 6 is arranged on the movable plate 5, the ground anchor 6 is located on the outside of the base 1, a limiting groove 7 is arranged on the inner wall of the base 1, a limiting block 8 is slidably connected to the inner wall of the limiting groove 7, and the limiting block One side of 8 is fixedly connected with a connecting plate 2 9, the bottom end of the connecting plate 2 9 is fixedly connected to the top of the moving plate 5, one side of the moving plate 5 is fixedly connected with a connecting block 10, the inner top wall of the base 1 is fixedly connected with a fixing rod 11, the bottom end of the fixing rod 11 is rotatably connected with a rotating ring 12, the bottom end of the rotating ring 12 is fixedly connected with a worm gear 13, the insides of the fixing rod 11, the rotating ring 12 and the worm gear 13 are all threadedly connected with a screw 14 located at the top of the connecting block 10, and the rear end of the base 1 is rotatably connected with a worm 15 meshing with the worm gear 13;

[0030] Specifically, the operator can install the device at the edge of the building construction, and then use the weight of the device to insert the ground anchor 6 into the ground, so that the device can be fixed. When encountering unevenness during the installation process, and the movable plate 5 and the ground anchor 6 are in a floating state, the worm 15 can be rotated at this time. Because the worm 15 is meshed with the worm wheel 13, the worm 15 will drive the worm wheel 13 and the rotating ring 12 to rotate, and then the rotating ring 12 and the worm wheel 13 will drive the screw rod 14 to rotate. Since the fixed rod 11, the rotating ring 12 and the worm wheel 13 are all threadedly connected to the screw rod 14, when the screw rod 14 rotates, the screw rod 1 4 will move downward, then the screw rod 14 will push the connecting block 10 and the moving plate 5 down, and while the moving plate 5 moves, the spring 1 4 will be stretched, and the connecting plate 2 9 will move, and then the connecting plate 2 9 will drive the limiting block 8 to move inside the limiting groove 7, and then the moving plate 5 will drive the anchor 6 to insert into the ground, so as to fix the device, and finally by adjusting the positions of the moving plate 5 and the anchor 6, the device can be adapted to the uneven ground, thereby enhancing its adaptability and stability to different terrain conditions, and effectively reducing the use drop or operation inconvenience caused by the uneven ground.

[0031] In this embodiment, a support plate 16 located on the surface of the worm 15 is fixedly connected to the inner wall of the rear side of the base 1, and a fixing ring 17 located inside the support plate 16 is fixedly connected to the surface of the worm 15. The limiting groove 7 and the limiting block 8 are both T-shaped designs, and the size of the limiting block 8 is adapted to the limiting groove 7. A baffle is fixedly connected to the surface of the anchor 6, and both sides of the baffle are in contact with the top and bottom ends of the movable plate 5 respectively;

[0032] Specifically, through the design of the support plate 16 and the fixing ring 17, when the worm 15 rotates, the worm 15 will drive the fixing ring 17 to rotate inside the support plate 16, and then the support plate 16 can support the worm 15, and the surface of the fixing ring 17 fits the inner wall of the support plate 16, so that the worm 15 can be limited to avoid the position shifting when the worm 15 rotates, affecting the normal rotation of the worm wheel 13. Through the design of the limiting groove 7 and the limiting block 8, since the limiting groove 7 and the limiting block 8 are both T-shaped designs, and the sizes of the limiting groove 7 and the limiting block 8 are adapted, the movable plate 5 can be limited when the limiting block 8 moves, so that the movable plate 5 moves smoothly, and a baffle is provided on the surface of the anchor 6, and the opposite side of the baffle is in contact with the top and bottom ends of the movable plate 5, so that the fixing effect of the anchor 6 can be increased.

[0033] In this embodiment, a contact block 18 is rotatably connected inside the connection block 10 . The contact block 18 is circular in design, and the top of the contact block 18 is on the same horizontal line as the top of the connection block 10 .

[0034] Specifically, through the design of the contact block 18, when the screw rod 14 rotates and descends, the bottom end of the screw rod 14 will contact the top end of the contact block 18, and through the friction between the screw rod 14 and the contact block 18, the screw rod 14 will drive the contact block 18 to rotate inside the connecting block 10, and then the screw rod 14 can easily push the connecting block 10 and the movable plate 5 to descend.

[0035] Embodiment 2:

[0036] like Figure 5 As shown, in this embodiment, mounting plates 19 are fixedly connected to both sides of the guardrail 2, a connecting rod 20 is provided at the top of the mounting plate 19, an infrared sensor 21 is fixedly connected to the front end of the connecting rod 20, and an alarm 22 is provided at the top of the guardrail 2;

[0037] Specifically, through the design of the infrared sensor 21 and the alarm 22, after the device is completed, the alarm 22 can monitor the surrounding environment, and when a violator is detected, the alarm 22 will drive the alarm 22, and then the alarm 22 will sound an alarm, thereby warning the violator to stay away from this area.

[0038] Embodiment three:

[0039] like Figure 5 and Figure 6As shown, in this embodiment, a swing mechanism is provided at the bottom end of the mounting plate 19, and the swing mechanism includes a fixed box 23 fixedly connected to the bottom end of the mounting plate 19, a gear ring 24 is slidably connected to the inner bottom wall of the fixed box 23, a motor 26 is fixedly connected to the bottom end of the fixed box 23, an output end of the motor 26 extends to the inside of the fixed box 23 and is coaxially fixed with a gear 1 25 located inside the gear ring 24, a rack 27 is fixedly connected to one side of the gear ring 24, a gear 2 28 is rotatably connected to the inner bottom wall of the fixed box 23, a linkage rod 29 is fixedly connected to the top end of the gear 28, and the linkage rod 29 passes through the mounting plate 19 upward and is fixedly connected to the bottom end of the connecting rod 20;

[0040] Specifically, through the design of the swing mechanism, in the process of the fixed box 23 monitoring the surrounding environment, the motor 26 can be driven to rotate the rack 27. Since the rack 27 is a half gear and meshes with the teeth inside the gear ring 24, when the rack 27 rotates, the teeth on the surface of the rack 27 will contact the teeth on both sides of the gear ring 24, and then the rack 27 will drive the gear ring 24 and the gear 1 25 to swing back and forth. Because the gear 1 25 is meshed with the gear 2 28, the gear 1 25 will drive the gear 2 28 to rotate back and forth during the swinging process, and then the gear 2 28 will drive the linkage rod 29 to rotate. Since the top end of the linkage rod 29 is fixedly connected to the bottom end of the connecting rod 20, the linkage rod 29 will drive the connecting rod 20 and the infrared sensor 21 to rotate back and forth. Finally, through the reciprocating rotation of the fixed box 23, the fixed box 23 can scan the surrounding environment in all directions, effectively reducing the monitoring blind area and improving the reliability of the device.

[0041] In this embodiment, a slide groove 32 is provided on the inner wall of the fixed box 23, a slider 33 is slidably connected to the inner wall of the slide groove 32, one side of the slider 33 is fixedly connected to one side of the gear ring 24, and springs 30 are fixedly connected to the inner walls of both sides of the fixed box 23, and push plates 31 are fixedly connected to the ends of the two springs 30 that are close to each other, and the sides of the two push plates 31 that are close to each other are in contact with the two sides of the gear ring 24 respectively;

[0042] Specifically, through the design of the slide groove 32 and the slider 33, when the gear ring 24 moves, the slider 33 will be driven to move inside the slide groove 32, and then the gear ring 24 can be limited to ensure that the gear ring 24 can move normally. Through the design of the spring 2 30 and the push plate 31, when the gear ring 24 swings back and forth, it will push the push plate 31 to move. When the push plate 31 moves, the spring 2 30 will be compressed, and then when the gear ring 24 moves away from the push plate 31, the compressed spring 2 30 will push the push plate 31, and then the opposite side of the push plate 31 will always be in contact with the surface of the gear ring 24, thereby increasing the stability of the movement of the gear ring 24.

[0043] Embodiment 4:

[0044] like Figure 1 and Figure 7 As shown, in this embodiment, a storage box 34 is provided on one side of the base 1, a second slide groove 35 is provided on the inner wall of the front side of the storage box 34, a sealing plate 36 is slidably connected to the inner wall of the second slide groove 35, and the bottom end of the anchor 6 is conical in design, and the anchor 6 is longitudinally symmetrically designed about the center of the guardrail 2;

[0045] Specifically, through the design of the storage box 34, the second slide groove 35 and the sealing plate 36, the operator pushes and pulls the sealing plate 36 to open the storage box 34, and then the counterweight block can be placed inside the storage box 34, thereby increasing the weight of the device and increasing the stability of the device. Through the design of the ground anchor 6, since the bottom end of the ground anchor 6 is conical in design, the ground anchor 6 can be easily inserted into the ground, and the ground anchor 6 is symmetrical in design. When the ground anchor 6 is subjected to external force, the force can be evenly dispersed, thereby avoiding deformation or damage caused by excessive force on a single point; this balanced force characteristic enables the ground anchor 6 to withstand greater external force, thereby improving the fixing effect of the device.

[0046] The specific working method is: when the early warning device for edge protection is used in the construction of the building, the operator can first put the counterweight block into the storage box 34, and then place the device on the edge of the construction site, and then use the weight of the device to insert the ground anchor 6 into the ground, so that the device can be fixed; and when encountering an uneven road surface, the worm 15 can be rotated, and the worm 15 will drive the worm wheel 13 and the screw rod 14 to rotate, and the screw rod 14 will move downward during the rotation, and then the bottom end of the screw rod 14 will contact the surface of the contact block 18, and will drive the contact block 18 to rotate, and then the screw rod 14 will push the connecting block 10 and the moving plate 5 to descend, and when the moving plate 5 descends, the spring 4 will be stretched, and the limit block 8 will move inside the limit groove 7, The movable plate 5 is limited, and then the anchor 6 is inserted into the ground to fix the device; after the fixation is completed, the infrared sensor 21 can monitor the surrounding environment. When a violator is detected, the alarm 22 will sound an alarm, thereby warning the violator to stay away from this area; during the monitoring process of the infrared sensor 21, the motor 26 can be driven to rotate the gear 1 25, and then the gear 1 25 will drive the gear ring 24 and the rack 27 to swing back and forth, and the rack 27 will drive the gear 2 28 to reciprocate during the movement, and then the gear 2 28 will drive the linkage rod 29, the connecting rod 20 and the infrared sensor 21 to reciprocate. Through the reciprocating rotation of the infrared sensor 21, the monitoring range of the infrared sensor 21 can be increased, and finally the operation process is completed.
