[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said that it is the process of turning various lines on the design drawings into physical objects at designated locations. As we all know, a large number of foundation pits will be generated during the construction process, so warning devices are generally used to remind people to be safe.

[0003] When the warning device is in use, the bracket needs to be propped open and the warning sign installed on the bracket. However, when the construction site is in an open area or around a high-rise building and encounters strong winds, the warning sign bracket is easily affected by the wind and topples over, which cannot play a good warning role. Personnel cannot discover the existence of the foundation pit in time, increasing the safety risks of workers and passers-by, and may cause accidents.

[0004] In view of this, we propose a foundation pit warning device for building construction. Utility Model Content

[0029] A foundation pit warning device for construction, comprising a support frame 1 and a warning sign 101, wherein the support frame 1 is divided into a mounting frame 102 and a leg 103, wherein the leg 103 is connected to the rear side of the mounting frame 102 through a rotating shaft, and the warning sign 101 is installed on the front side of the support frame 1, and reinforcement mechanisms are arranged on both sides of the support frame 1; the reinforcement mechanism comprises a reinforcement rod 201, a movable rod 202, a limiting hole 203, a shaft 204, a gear 205, a toothed part 206, a limiting rod 207 and a spring 208, wherein one end of the reinforcement rod 201 is connected to the outer side of the leg 103 through a rotating shaft, and one end of the movable rod 202 is slidably connected to the inside of the reinforcement rod 201 and penetrates to the other end of the reinforcement rod 201 The movable rod 202 has an end, and the other end is connected to the outside of the mounting frame 102. The limiting holes 203 are opened at the top and bottom of the inner wall of the reinforcing rod 201. There are several limiting holes 203, which are evenly distributed at the top and bottom of the inner wall of the reinforcing rod 201. The shaft 204 is fixedly connected to the inside of the movable rod 202. The gear 205 is sleeved on the surface of the shaft 204. The gear 206 is meshed and connected to the front and rear sides of the gear 205. One end of the limiting rod 207 is fixedly connected to the end of the gear 206. The other end of the limiting rod 207 passes through the movable rod 202 and extends to the inside of the limiting hole 203. One end of the spring 208 is fixedly connected to the end of the gear 206. The other end of 208 is fixedly connected to the inner wall of the movable rod 202. When using the warning device, first install the warning sign 101 on the front side of the mounting frame 102, then expand the legs 103 to support the support frame 1 on the ground, and then flexibly adjust the movable rod 202 according to the expansion angle of the mounting frame 102 and the legs 103. When adjusting the movable rod 202, the movable rod 202 can be pulled to slide inside the reinforcement rod 201. When the movable rod 202 slides, the limiting rod 207 can be squeezed out of the limiting hole 203. When the limiting rod 207 is separated from the limiting hole 203, it will squeeze the tooth 206 and the spring 208. When it is adjusted to a suitable length, the spring 208 can be used to release the tooth 206 and the spring 208. The gear 206 and the limit rod 207 are pushed to move outward under the rebound force, and the movement of the gear 206 will drive the gear 205 to rotate on the surface of the shaft 204, that is, the two gears 206 and the limit rod 207 are pushed to move at the same time under the rotation of the gear 205, and the limit rod 207 passes through the movable rod 202 and is adapted to the limit hole 203, so that the movable rod 202 can be limited and fixed inside the reinforcement rod 201, and then the outer end of the movable rod 202 is connected to the outer side of the mounting frame 102, so that the support frame 1 can be reinforced and supported with the cooperation of the reinforcement mechanism, and the overall bearing capacity of the bracket is increased to prevent the support frame 1 from being deformed or tipped over due to strong wind or external force.

[0030] Specifically, the outer side of the tooth 206 is fixedly connected to the limit block 301, the inner wall of the movable rod 202 is fixedly connected to the sliding rod 302, and the limit block 301 is slidably connected to the surface of the sliding rod 302. When the tooth 206 moves, it will drive the limit block 301 to slide on the surface of the sliding rod 302, thereby playing an auxiliary limiting role for the tooth 206, avoiding the displacement of the tooth 206 during movement, and causing the tooth 206 to be disconnected from the gear 205, thereby affecting the normal operation of the reinforcement mechanism.

[0031] Furthermore, sliders 401 are fixedly connected to both sides of the movable rod 202, and sliding grooves 402 used in conjunction with the sliders 401 are provided on both sides of the inner wall of the reinforcement rod 201. When the movable rod 202 slides inside the reinforcement rod 201, the movable rod 202 will drive the slider 401 to slide inside the sliding groove 402, thereby limiting the movable rod 202 from moving parallel inside the reinforcement rod 201, and with the cooperation of the slider 401 and the sliding groove 402, the movable rod 202 can be limited from detaching from the interior of the reinforcement rod 201 when moving.

[0032] It is worth mentioning that the spring 208 is internally movable and is provided with a telescopic part 5, one end of the telescopic part 5 is fixedly connected to the inner wall of the movable rod 202, and the other end of the telescopic part 5 is fixedly connected to the end of the toothed part 206. The telescopic part 5 can provide more precise control to meet the telescopic performance of the spring 208 during work, and can push the limit rod 207 and the limit hole 203 to be more stably connected under the elastic force of the telescopic part 5.

[0033] It is worth noting that the surface of the shaft 204 is sleeved on the limiting ring 6, and the limiting ring 6 is respectively located on both sides of the gear 205. When the gear 205 rotates on the surface of the shaft 204, the gear 205 can be limited on the surface of the shaft 204 under the action of the limiting ring 6, thereby preventing the gear 205 from being displaced on the surface of the shaft 204 when rotating.

[0034] In addition, circular holes 7 are provided at the top and bottom of the movable rod 202, and the diameter of the circular hole 7 is adapted to the limiting rod 207, so that the limiting rod 207 can pass through the movable rod 202 and can move flexibly inside the circular hole 7 to prevent the limiting rod 207 from colliding with the movable rod 202 and causing motion interference when moving.

[0035] It must be mentioned that the end of the limiting rod 207 is set as a slope, and the slope is used in conjunction with the limiting hole 203. When the limiting rod 207 is squeezed out of the inside of the limiting hole 203, the friction resistance between the limiting rod 207 and the limiting hole 203 can be reduced under the action of the slope, and the limiting rod 207 can be moved more flexibly and connected with the limiting hole 203.

[0036] Working principle: when the warning device is in use, first install the warning sign 101 on the front side of the mounting frame 102, then expand the legs 103 to support the support frame 1 on the ground, and then flexibly adjust the movable rod 202 according to the expansion angle of the mounting frame 102 and the legs 103. When adjusting the movable rod 202, the movable rod 202 can be pulled to slide inside the reinforcement rod 201. When the movable rod 202 slides, it can squeeze the limit rod 207 out of the limit hole 203. When the limit rod 207 is out of the limit hole 203, it will squeeze the tooth 206 and the spring 208. When it is adjusted to a suitable length, the spring 208 can be The rebound force pushes the toothed part 206 and the limiting rod 207 to move outward again, and the movement of the toothed part 206 will drive the gear 205 to rotate on the surface of the shaft 204, that is, the two toothed parts 206 and the limiting rod 207 can be pushed to move at the same time under the rotation of the gear 205, and the limiting rod 207 can pass through the movable rod 202 and adapt to the limiting hole 203, so that the movable rod 202 can be limited and fixed inside the reinforcement rod 201, and then the outer end of the movable rod 202 is connected to the outer side of the mounting frame 102, so that the support frame 1 can be reinforced and supported with the cooperation of the reinforcement mechanism to prevent the support frame 1 from being deformed or tipped over due to strong wind or external force.
