Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a slope collapse detection device. Background Art

[0002] During subway construction, it is often necessary to dig tunnels underground. During the tunnel digging process, the excavated tunnel slopes need to be detected in real time to prevent tunnel collapse. However, due to structural and functional limitations, existing detection devices can usually only perform simple detection of collapse displacements. They are not sensitive enough to effectively detect the slope displacement trend before collapse, thereby making early warnings. Warnings are often issued only after collapse occurs, which makes the warnings not timely enough and poses safety hazards. Utility Model Content

[0003] In view of the defects in the prior art, the purpose of the present invention is to provide a slope collapse detection device that can promptly remind operators of abnormalities in the passage slope, provide timely warnings, and ring a bell to sound a warning, thereby improving safety.

[0004] A slope collapse detection device comprises a base, a support rod is fixedly connected to the top of the base, a rotating frame is fixedly connected to the top of the support rod, a rotating block is rotatably connected to the rotating frame, two torsion springs are connected between the rotating block and the rotating frame, a support plate is fixedly connected to the rotating block, an annular block is fixedly connected to the rotating block, a warning component and a sounding component are provided on the base, the warning component is used to remind construction personnel of abnormalities in the slope, and the sounding component is used to sound an alarm, which can better remind construction personnel.

[0005] Optionally, the warning component includes a transmission rod, which is slidably connected to the support rod, a pressure spring is connected between the transmission rod and the support rod, the top of the transmission rod is in contact with the annular block, a rocker arm is rotatably connected to the base, a rotating cylinder is rotatably connected to the base, a warning plate is fixedly connected to the rotating cylinder, two torsion springs are connected between the warning plate and the rotating cylinder, and the warning plate and the rocker arm are connected by a snap.

[0006] Optionally, the sounding component includes a bracket, the bracket is fixedly connected to the base, a bell is rotatably connected to the bracket, and a top block is fixedly connected to the warning plate.

[0007] Optionally, a plurality of nail blocks are provided at the bottom of the base so that the device can better grip the ground.

[0008] Optionally, the support plate is a plastic plate to reduce gravity and improve detection sensitivity.

[0009] The utility model has the following advantages: 1. When the support plate is squeezed by the slope, the support plate will rotate toward the support rod. Once the torsion spring is twisted, the rotation of the support plate will drive the rotating block to rotate, and the rotation of the rotating block will drive the annular block to rotate. The rotation of the annular block will squeeze the transmission rod, and the transmission rod will be squeezed and dropped. The pressure spring is compressed, and the transmission rod will be squeezed and dropped to hit the swing rod, and the swing rod will swing counterclockwise when hit. The swing of the swing rod will separate from the warning plate, and the second resetting of the torsion spring will drive the reset of the warning plate, and the reset of the warning plate will lift up, so that the operator can be promptly reminded that there is an abnormality in the slope of the passage.

[0010] 2. The second reset of the torsion spring will drive the warning plate to reset, and the reset of the warning plate will drive the top block to rotate in the direction of the bell, so that the top block will hit the bell, causing the bell to emit a warning sound. After the abnormality is eliminated, the warning plate rotates to drive the top block and the bell to separate, so that further warnings can be given to the operator, improving safety.

After the abnormal contact, the support plate 5 is no longer squeezed, and the reset of the torsion spring 17 drives the reset of the support plate 5. The reset of the support plate 5 drives the reset of the rotating block 4 and the annular block 6. The transmission rod 8 is no longer squeezed by the annular block 6.
