Description

Technical Field

[0001] The invention relates to the technical field of tilt warning devices, and in particular to a building tilt warning device and a warning method for monitoring a construction project. Background Art

[0002] In construction projects or safety monitoring of existing buildings, building tilt warning equipment is used to monitor the tilt, settlement or deformation of a building in real time, and issue an alarm when the safety threshold is exceeded to prevent structural instability or collapse accidents.

[0003] The patent with patent announcement number CN218884948U relates to a tilt warning device for monitoring construction projects, including an L-shaped plate, which is composed of a combination of mutually perpendicular horizontal plates and vertical plates. The top of one side of the vertical plate of the L-shaped plate is fixedly connected to a top beam, one side of the bottom of the top beam is fixedly connected to a hanging rope, the bottom of the hanging rope is fixedly connected to a laser transmitter, the middle of the top of the horizontal plate of the L-shaped plate is fixedly connected to a base, the top of the base is fixedly installed with a laser receiver, and the front of the base is installed with a warning component. The tilt warning device for monitoring construction projects provided by the patent can determine whether the building ground is tilted by whether the laser of the laser transmitter can be received by the laser receiver. Regardless of whether the hanging rope is offset forward or backward or left or right in the line of sight, the result can be directly and accurately obtained. It also has a warning function. In addition, the laser transmitter is clamped and fixed to avoid arbitrary swinging and collision damage during movement.

[0004] The above patent has the function of preventing the laser transmitter from swinging randomly. By clamping the laser transmitter, it is prevented from swinging randomly and being damaged by collision when moving, thereby ensuring the stable progress of the monitoring operation. However, in the actual monitoring process, since the operator needs to first make the L-shaped plate in stable contact with the building structure, the operator needs to adjust the position of the L-shaped plate many times during this process, which will cause the laser receiver to shake. This shaking will not only affect the stability of the laser receiver, but also interfere with the operator's adjustment work, making the adjustment process more cumbersome and unstable.

[0015] The present invention provides a building tilt warning device for monitoring construction projects. It has the following beneficial effects: (1) In the building tilt warning device used for monitoring construction projects, the limit rod fits tightly with the blind hole, and the inclinometer provides additional support for the limit rod. The close fit between the limit rod and the blind hole ensures that the plate remains in a more stable state after adjustment, thereby effectively ensuring the stability of the touch sensor on the plate.

[0017] (3) In the building tilt warning device used for monitoring construction projects, the sliding plate provides additional stability for the cylindrical rod. The sliding plate provides additional support for the cylindrical rod, ensuring that the cylindrical rod is more stable during the adjustment process, which helps to improve the accuracy and efficiency of the adjustment operation. At the same time, the downward movement speed of the inclined plate is slowed down by the reverse elastic force.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0021] See also Figure 1 - Figure 7 One embodiment of the present invention is: a building tilt warning device for monitoring a construction project, comprising: a support frame 1, the support frame 1 is fixed to the surface of the building structure to be measured by anchor bolts; an inclinometer 2, the inclinometer 2 is fixedly mounted on the surface of the support frame 1, the inclinometer 2 is provided with an arc scale, and the inclinometer 2 is provided with a rotating shaft; a pendulum 3, the pendulum 3 is hinged on the rotating shaft of the inclinometer 2; a round rod 4, the round rod 4 is fixedly mounted on a side of the pendulum 3 away from the inclinometer 2; a carrying frame 5, the carrying frame 5 is fixedly mounted on the surface of the support frame 1; a lifting rod 6, the lifting rod 6 is slidably mounted on the carrying frame 5 At the top, a guide groove is provided on the circumferential surface of the lifting rod 6; a flat plate 7, which is fixedly mounted on the top of the lifting rod 6; two touch sensors 8, which are fixedly mounted on the top of the flat plate 7, and an alarm module is arranged inside the touch sensor 8; a sleeve 9, which is rotatably mounted on the circumferential surface of the mounting frame 5; two stop blocks 10, which are fixedly mounted on the inner wall of the sleeve 9, and the stop blocks 10 are in contact with the inner wall of the guide groove. By adjusting the height of the touch sensor 8, it can not only ensure that the inclinometer 2 can independently complete the tilt measurement, but also accurately trigger the alarm through the touch sensor 8.

[0022] A linkage rod 11 is fixedly installed at the bottom of the lifting rod 6, and a fixing frame 12 is fixedly installed at the bottom of the flat plate 7. The fixing frame 12 is provided with an internal threaded through hole, and a screw 13 is threadedly connected to the inner wall of the fixing frame 12. A limit rod 14 is fixedly installed on the side of the screw 13 close to the inclinometer 2, and a blind hole is provided on the side of the inclinometer 2 close to the pendulum 3. The limit rod 14 fits tightly with the blind hole, thereby ensuring that the flat plate 7 remains in a more stable state after adjustment, thereby effectively ensuring the stability of the touch sensor 8 on the flat plate 7.

[0023] The two touch sensors 8 are symmetrically arranged about the central vertical axis of the flat plate 7. A torsion spring is arranged between the sleeve 9 and the mounting frame 5. The stop block 10 contacts the top of the mounting frame 5. By arranging the torsion spring, after the operator rotates the sleeve 9, the sleeve 9 can automatically rotate, thereby improving the convenience of operation.

[0024] A warning method of a building tilt warning device for monitoring a construction project, using the above-mentioned building tilt warning device for monitoring a construction project, comprises the following steps: Step 1: The operator first places the support frame 1 on the surface of the building structure to be monitored, and then observes the position of the pendulum 3 and the arc scale on the inclinometer 2; Step 2: When the pendulum 3 is found to be deflected, the operator needs to fine-tune the position of the support frame 1 until the pendulum 3 returns to a vertical state; Step 3: After confirming that the position is correct, the operator uses anchor bolts to firmly fix the support frame 1 on the surface of the building structure. After the fixation is completed, the operator adjusts the height of the touch sensor 8 to keep it parallel to the round rod 4; Step 4: When the monitored building structure tilts, the support frame 1 tilts accordingly, and the touch sensor 8 contacts the round rod 4 during the tilt. After the touch sensor 8 detects the contact signal, it immediately triggers the alarm module to sound an alarm.

[0025] When the present embodiment is working, the operator first places the support frame 1 on the surface of the building structure to be monitored, and then observes the position of the pendulum 3 and the arc scale on the inclinometer 2. If the pendulum 3 is found to be deflected, the operator needs to fine-tune the position of the support frame 1 until the pendulum 3 returns to a vertical state. After confirming that the position is correct, the operator uses anchor bolts to firmly fix the support frame 1 on the surface of the building structure. After the fixation is completed, the operator performs a height adjustment operation on the touch sensor 8, and rotates the sleeve 9 counterclockwise with one hand. The sleeve 9 stretches the torsion spring during the rotation, and drives the stop block 10 to rotate synchronously. The stop block 10 moves to the guide After the lifting rod 6 reaches the specified position in the groove, the limit of the vertical direction of the lifting rod 6 is released, and the other hand pulls the flat plate 7 upward. The movement of the flat plate 7 drives the lifting rod 6 and the touch sensor 8 to move upward synchronously. The movement of the lifting rod 6 drives the linkage rod 11 to move upward. When the lifting rod 6 reaches the predetermined position, the operator releases the sleeve 9. At this time, the deformed torsion spring begins to recover. The recovery of the torsion spring drives the sleeve 9 to rotate clockwise. The rotation of the sleeve 9 drives the stop block 10 to rotate synchronously. After the stop block 10 rotates to the specified position in the guide groove, the lifting rod 6 is limited again and cannot move vertically, thereby completing the height adjustment of the touch sensor 8. When the building structure being measured tilts, the support frame 1 tilts accordingly, and the touch sensor 8 contacts the round rod 4 during the tilting. After the touch sensor 8 detects the contact signal, the alarm module is immediately triggered to sound an alarm. By adjusting the height of the touch sensor 8, it is possible to ensure that the inclinometer 2 can independently complete the tilt measurement, and the alarm can be accurately triggered by the touch sensor 8, thereby effectively improving the accuracy of monitoring. When the flat plate 7 moves upward, the flat plate 7 drives the fixed frame 12 to move upward synchronously. When the lifting rod 6 reaches the predetermined position and is limited by the stop block 10, the operator manually rotates the screw 13 counterclockwise to move it toward the inclinometer 2. The screw rod 13 moves and drives the limit rod 14 to move synchronously in the direction of the inclinometer 2 until the limit rod 14 is tightly fitted with the blind hole on the inclinometer 2. At this time, the inclinometer 2 provides additional support for the limit rod 14 through the blind hole to ensure that the height of the tablet 7 remains stable after adjustment. When it is necessary to release the contact between the limit rod 14 and the blind hole, the operator only needs to rotate the screw rod 13 clockwise to withdraw the limit rod 14 from the blind hole. The close fit between the limit rod 14 and the blind hole ensures that the tablet 7 remains in a more stable state after adjustment, thereby effectively ensuring the stability of the touch sensor 8 on the tablet 7.

[0026] See also Figure 1 - Fig. 9On the basis of the above embodiment, in another embodiment of the present invention, a power-assisting device for improving the adjustment efficiency is provided on the mounting frame 5, and a protective device for ensuring the safety of the adjustment is provided in the power-assisting device; the power-assisting device includes a loading frame 141, a convex rod 142, a compression spring 143 and a cylindrical rod 144, the loading frame 141 is fixedly mounted on the surface of the mounting frame 5, the convex rod 142 is slidably mounted on the inner wall of the loading frame 141, the compression spring 143 is arranged between the convex rod 142 and the loading frame 141, the cylindrical rod 144 is fixedly mounted on the circumferential surface of the convex rod 142, the convex rod 142 is in contact with the bottom of the linkage rod 11, and the convex rod 142 provides auxiliary thrust for the linkage rod 11, thereby effectively reducing the physical exertion required for the operator to manually adjust the touch sensor 8, making the height adjustment more labor-saving and efficient.

[0027] A rotating shaft 145 is rotatably passed through the circumferential surface of the convex rod 142, a triangular plate 146 is fixedly installed on the circumferential surface of the rotating shaft 145, and blocking blocks 147 are fixedly installed on the outer wall surfaces on both sides of the loading frame 141. Through simple operation, the operator can quickly enable or disable the auxiliary thrust of the convex rod 142, thereby improving the flexibility and convenience of operation when monitoring the tilt of the building.

[0028] A slide groove is provided on one side of the loading frame 141 close to the cylindrical rod 144, and the cylindrical rod 144 contacts the inner wall of the slide groove. The slide groove ensures that the cylindrical rod 144 moves accurately in a predetermined direction.

[0029] The protective device includes a fixed frame 151, a sliding plate 152, a vertical rod 153, a C-shaped tube 154, two inclined plates 155, a connecting frame 156 and a rotating piece 157. The fixed frame 151 is fixedly installed inside the loading frame 141, the sliding plate 152 slides through the inner and outer walls of the fixed frame 151, the vertical rod 153 is fixedly installed on the top of the sliding plate 152, the C-shaped tube 154 is fixedly installed on the top of the vertical rod 153, the two inclined plates 155 are fixedly installed on the bottom of the sliding plate 152, the connecting frame 156 is fixedly installed on the inner wall of the fixed frame 151, the rotating piece 157 rotates and passes through the inner and outer walls of the connecting frame 156, the C-shaped tube 154 contacts the circumferential surface of the cylindrical rod 144, and provides additional support force for the cylindrical rod 144 through the sliding plate 152, ensuring that the cylindrical rod 144 is more stable during the adjustment process, which helps to improve the accuracy and efficiency of the adjustment operation.

[0030] The side of the inclined plate 155 away from the sliding plate 152 is provided with an arc surface, and the rotating piece 157 itself is elastic. The side of the rotating piece 157 close to the sliding plate 152 contacts the inner wall of the connecting frame 156. The inclined plate 155 squeezes the rotating piece 157 and utilizes the elasticity of the rotating piece 157 to slow down the downward movement speed of the inclined plate 155, thereby ensuring that the linkage rod 11 can smoothly restore downward.

[0031] When the present embodiment is working, when the linkage rod 11 moves upward, the originally compressed compression spring 143 gradually releases its elastic force to apply an upward thrust to the convex rod 142. The convex rod 142 moves upward under the action of the thrust, and the movement of the convex rod 142 drives the cylindrical rod 144 to move upward, and applies a continuous auxiliary thrust to the bottom of the linkage rod 11 until the linkage rod 11 reaches the predetermined position and disengages from the convex rod 142. After the monitoring is completed, when the linkage rod 11 is reset downward, its bottom contacts the top of the convex rod 142, so that the linkage rod 11 continues to move and applies continuous pressure to the convex rod 142. The convex rod 142 moves downward under the action of the pressure, and the convex rod 142 squeezes the compression spring 143 during the movement, so that it accumulates elastic potential energy, and provides an auxiliary thrust for the next rise of the linkage rod 11. The convex rod 142 provides an auxiliary thrust for the linkage rod 11, which effectively reduces the physical effort required for the operator to manually adjust the touch sensor 8, making the height adjustment more labor-saving and efficient. When the rod 142 provides auxiliary thrust, the operator manually rotates the triangular plate 146 in the direction away from the loading frame 141, and the rotation of the triangular plate 146 drives the rotating shaft 145 to rotate synchronously. When the triangular plate 146 rotates to contact with the blocking block 147, it stops. The blocking block 147 not only limits the rotation range of the triangular plate 146, but also provides it with additional support to ensure that the triangular plate 146 remains at a specified angle. At this time, the linkage rod 11 moves upward, and the compression spring 143 restores and pushes the convex rod 142 to move upward. The movement of the convex rod 142 drives the rotating shaft 145 to move upward, and the movement of the rotating shaft 145 drives the triangular plate 146 to move upward. After the triangular plate 146 moves upward, it is in close contact with the inner wall of the loading frame 141. The contact forms a limit to prevent the convex rod 142 from continuing to move upward. At this time, the linkage rod 11 continues to move upward and disengages from the convex rod 142. Through simple operation, the operator can quickly enable or disable the auxiliary thrust of the convex rod 142, thereby improving the flexibility and convenience of operation when monitoring the inclination of the building. When the cylindrical rod 144 moves upward, the cylindrical rod 144 moves to drive the C-shaped tube 154 to move upward synchronously, and the C-shaped tube 154 drives the vertical rod 153 to move upward. The movement of the vertical rod 153 further drives the sliding plate 152 to move smoothly upward along the slide groove. During the movement of the sliding plate 152, the sliding plate 152 transmits the supporting force to the cylindrical rod 144 through the vertical rod 153, providing it with additional stability, ensuring that the movement of the cylindrical rod 144 is more stable and smooth. At the same time, the movement of the sliding plate 152 drives the inclined plate The inclined plate 155 moves upward synchronously, and the inclined plate 155 contacts the side of the rotating piece 157 close to the sliding plate 152 during the movement. The inclined plate 155 applies an upward thrust to the rotating piece 157. Under the action of the thrust, the rotating piece 157 rotates upward until it is out of contact with the inclined plate 155. The rotating piece 157 naturally falls back to the initial position under the action of gravity, and the sliding plate 152 provides additional support for the cylindrical rod 144, ensuring that the cylindrical rod 144 is more stable during the adjustment process, which helps to improve the accuracy of the adjustment operation. In order to improve the performance and efficiency, when the cylindrical rod 144 is reset downward, the cylindrical rod 144 moves and drives the C-shaped tube 154 to move downward, and the C-shaped tube 154 further drives the vertical rod 153 to move downward, and the vertical rod 153 moves and drives the sliding plate 152 to move downward, and the sliding plate 152 moves and drives the inclined plate 155 to move downward, and the arc surface of the inclined plate 155 contacts the side of the rotating piece 157 away from the sliding plate 152 during the movement, and the rotating piece 157 is supported by the connecting frame 156 and cannot rotate, so that the inclined plate 155 continues to move downward. The rotating piece 157 is moved and squeezed, and the deformed rotating piece 157 applies a reverse elastic force to the inclined plate 155. The downward movement speed of the inclined plate 155 is slowed down under the action of the reverse elastic force. When the inclined plate 155 loses contact with the deformed rotating piece 157, the rotating piece 157 will quickly return to its initial state. The rotating piece 157 is squeezed by the inclined plate 155 and the elasticity of the rotating piece 157 is utilized to slow down the downward movement speed of the inclined plate 155, thereby ensuring that the linkage rod 11 can smoothly return downward, which helps to improve the safety of operation.
