Description

TECHNICAL FIELD

[0001] The utility model relates to the field of scaffold monitoring, especially to a scaffold offset monitoring device based on MEMS technology. BACKGROUND

[0002] Scaffold is a common construction tool in engineering, which can be used to enable workers to climb to high places to perform high-altitude work. Monitoring the scaffold has the effects of improving construction safety, indirectly improving construction quality and construction efficiency, facilitating the maintenance of the scaffold, etc.

[0003] In the prior art, only some conventional monitoring equipment can be used to monitor the overall scaffold, and the monitoring objects usually include the inclination angle and offset of the scaffold. For example, the overall inclination angle or offset of the scaffold is monitored by using conventional monitoring equipment. However, since the scaffold has four legs, each leg is subjected to force alone, and when a leg slightly deviates, the overall scaffold may not tilt or deviate, but the safety risk of the scaffold is greatly increased in this case. However, the scaffold monitoring equipment in the prior art cannot independently monitor the inclination and deviation of each leg of the scaffold, so when analyzing the monitoring results, errors and inaccurate analysis may occur, which is not conducive to ensuring the safety, quality and efficiency of construction.

[0066] The working process of the utility model will be described as follows:

[0067] Preferably, as shown in the drawings, Figures 1 to 5As shown, in the embodiment, the rotating lever mechanisms 2, the supporting arm mechanisms 3 and the telescopic mechanisms 6 are all four, the two rotating lever mechanisms 2 in each group are arranged at 180 degrees, and the two supporting arm mechanisms 3 in each group are also arranged at 180 degrees; for the convenience of understanding, the four rotating lever mechanisms 2 are respectively expressed as a first rotating lever mechanism, a second rotating lever mechanism, a third rotating lever mechanism and a fourth rotating lever mechanism, the first rotating lever mechanism and the third rotating lever mechanism are arranged at 180 degrees, and the second rotating lever mechanism and the fourth rotating mechanism are arranged at 180 degrees; the four supporting arm mechanisms 3 are respectively expressed as a first supporting arm mechanism, a second supporting arm mechanism, a third supporting arm mechanism and a fourth supporting arm mechanism, the first supporting arm mechanism and the third supporting arm mechanism are arranged at 180 degrees, and the second supporting arm mechanism and the fourth supporting arm mechanism are arranged at 180 degrees; the scaffold to be monitored has four legs, and the four legs are distributed according to the four vertices of a rectangle, for the convenience of understanding, the four legs are respectively expressed as a first leg, a second leg, a third leg and a fourth leg, the first leg and the third leg are arranged diagonally, and the second leg and the fourth leg are arranged diagonally;

[0069] Firstly, the push rod 331 in the first supporting arm mechanism is pushed towards the shell 1, so that the telescopic supporting arm 31 slides in the rotating lever body 21, at this time, the telescopic mechanism 6 is compressed, when the distance between the clamping jaws 32 in the first supporting arm mechanism and the clamping jaws 32 in the third supporting arm mechanism is less than the distance between the two diagonally arranged legs (i.e. the first leg and the third leg) in the scaffold to be monitored, the clamping jaws 32 in the third supporting arm mechanism abut against the side wall of the third leg, the height of the clamping jaws 32 in the first supporting arm mechanism is adjusted, so that the clamping jaws 32 in the first supporting arm mechanism and the clamping jaws 32 in the third supporting arm mechanism are substantially at the same height, then the push rod 331 in the first supporting arm mechanism is released, and then the clamping jaws 32 in the first supporting arm mechanism abut against the side wall of the first leg under the resilience of the telescopic mechanism 6;

[0070] Then, rotate the second rotating lever mechanism, the rotating lever body 21 in the second rotating lever mechanism drives the first gear shaft 513 fixedly connected therewith to rotate forward, the first gear shaft 513 drives the first gear 512 to rotate reversely, and the first gear 512 drives the first gear shaft 513 fixedly connected with the rotating lever body 21 in the fourth rotating lever mechanism to rotate forward, so that the second rotating lever mechanism and the fourth rotating lever mechanism rotate in the same direction, and the clamping jaw 32 in the second supporting arm mechanism and the clamping jaw 32 in the fourth supporting arm mechanism rotate in the same direction to approximately face the second supporting leg and the fourth supporting leg, and at this time, the distance between the clamping jaw 32 in the second supporting arm mechanism and the clamping jaw 32 in the fourth supporting arm mechanism is greater than the distance between the second supporting leg and the fourth supporting leg;

[0071] Then, the push rod 331 in the second supporting arm mechanism is pushed towards the shell 1, so that the telescopic supporting arm 31 slides in the rotating lever body 21, at this time, the telescopic mechanism 6 is compressed, when the distance between the clamping jaw 32 in the second supporting arm mechanism and the clamping jaw 32 in the fourth supporting arm mechanism is less than the distance between the second supporting leg and the fourth supporting leg, the second rotating lever mechanism is continuously rotated, so that the clamping jaw 32 in the fourth supporting arm mechanism abuts against the side wall of the fourth supporting leg, the height of the clamping jaw 32 in the second supporting arm mechanism is adjusted, so that the clamping jaw 32 in the second supporting arm mechanism and the clamping jaw 32 in the fourth supporting arm mechanism are substantially at the same height, then the push rod 331 in the second supporting arm mechanism is released, so that the clamping jaw 32 in the second supporting arm mechanism abuts against the side wall of the second supporting leg under the rebound force of the telescopic mechanism 6, and the fixing of the device on the scaffold is completed.

[0072] Finally, the first sensor 41 is located in the middle of the shell 1, and is also substantially located in the middle of the scaffold, the inclination angle and acceleration of the whole scaffold are monitored in real time through the first sensor 41, the inclination angle and acceleration of the four legs of the scaffold are monitored in real time through the four second sensors 42, and the offset of the whole scaffold and the four legs can be calculated according to the values of the inclination angle and acceleration through the MEMS sensor.

[0073] Compared with the prior art, the device has the following advantages:

[0074] 1. In this utility model, by setting an adjustment mechanism, the two rotating rod mechanisms in each group of rotating rod mechanisms will rotate in the same direction. If the four legs of the scaffold are regarded as four points, then the four points can form a rectangle. Since the two rotating rod mechanisms in each group of rotating rod mechanisms will rotate in the same direction, when the four grippers 32 of this device abut against the four legs of the scaffold, they will definitely be at the center of the rectangle. The four telescopic mechanisms will use elastic force to pop out the support arm mechanism so that each gripper abuts against each leg of the scaffold. The anti-slip pad mainly plays an anti-slip role, so that there is a large static friction between the gripper and the leg of the scaffold to prevent the device from falling off. When this device is installed, the shell and the first sensor on it will be located in the middle position of the four legs of the scaffold, that is, the center of gravity of the entire scaffold. At this time, the first sensor can be used to monitor the overall tilt and acceleration of the scaffold in real time. The overall offset of the scaffold can be calculated based on the tilt angle and acceleration values.

[0075] 2. In this utility model, four grippers respectively abut against the four legs of the scaffold. Therefore, the four second sensors can be used to monitor the tilt angle and acceleration of the four legs of the scaffold in real time. The offset of the four legs of the scaffold can be calculated based on the values ​​of the tilt angle and acceleration, and thus, in conjunction with the overall displacement of the scaffold, it can be used to determine whether the scaffold is in a safe state.
