Description

Technical Field

[0001] This utility model relates to the field of bridge rotation technology, and in particular to a force sensor for rotating bridges. Background Technology

[0002] In existing technologies, when rotating a bridge beam, the beam is usually rotated by using a crane to lift and place counterweights at predetermined positions on the beam ends before rotation, thereby changing the beam's center of gravity and thus altering the beam's posture to achieve the purpose of posture adjustment.

[0003] However, the stress on existing bridge bases cannot be monitored in real time. The tilt of the bridge can only be observed by the naked eye when the bridge tilts excessively, which leads to untimely adjustment of the counterweight. Therefore, the stress on existing bridge bases cannot be monitored in real time. Thus, a stress sensor for rotating bridges is proposed. Utility Model Content

[0004] To address at least one of the aforementioned technical shortcomings, this utility model provides a force sensor for a rotating bridge, comprising at least four force sensor units. Each force sensor unit includes a pressure sensor. An electric push rod is coaxially mounted on the support end at the bottom of the pressure sensor, and a connecting assembly is coaxially mounted on the detection end at the top of the pressure sensor. The connecting assembly is movably connected to the lower surface edge of the bridge base or the lower surface of the turntable. A display controller is fixedly connected to the outer wall of the pressure sensor.

[0005] Preferably, the connecting assembly includes a connecting sleeve fitted onto the detection end of the pressure sensor, and the top of the connecting sleeve is rotatably connected to a connecting ball through a spherical hole.

[0006] Furthermore, the main board of the display controller is equipped with a synchronization module for controlling the synchronous lifting and lowering of the electric push rod.

[0007] Furthermore, the display controller is equipped with a speaker and an alarm light.

[0008] Furthermore, the support end at the bottom of the pressure sensor and the telescopic end of the electric actuator are connected by a flange.

[0009] Furthermore, a flange is fixedly connected to the bottom end of the cylinder of the electric actuator.

[0010] Furthermore, the outer wall of the cylinder of the electric actuator is provided with a concave annular groove, the inside of which is filled with a colored liquid, and a sealing ring made of transparent material is provided at the opening of the annular groove. The outer wall of the sealing ring is provided with several equidistant circular scale lines.

[0011] Beneficial effects:

[0012] 1. During installation, four force sensor units are arranged in a circular array on the chassis of the rotating device or on the ground around the chassis. The connecting components are supported on the lower surface of the bridge base or the lower surface of the turntable of the rotating device. The force sensor units simultaneously detect the pressure in the circumferential area of ​​the bridge base, allowing construction personnel to obtain the force on the bridge base at any time through the display controller, thereby inferring whether the bridge has tilted.

Detailed Implementation

[0017] Please refer to Figures 1 to 2 ;

[0018] This embodiment provides a force sensor for a rotating bridge, including at least four force sensor units 1. Each force sensor unit 1 includes a pressure sensor 11. An electric push rod 12 is coaxially mounted on the support end at the bottom of the pressure sensor 11. A connecting assembly 13 is coaxially mounted on the detection end at the top of the pressure sensor 11. The connecting assembly 13 is movably connected to the lower surface edge of the bridge base or the lower surface of the turntable. A display controller 14 is fixedly connected to the outer wall of the pressure sensor 11.

[0019] In practical implementation, during installation, four force sensor units 1 are installed in a circular array on the chassis of the rotating device or on the ground around the chassis, so that the connecting component 13 is supported on the lower surface of the bridge base or the lower surface of the turntable of the rotating device. The force sensor units 1 simultaneously detect the pressure in the circumferential area of ​​the bridge base, so that the construction personnel can obtain the force on the bridge base at any time through the display controller 14, thereby inferring whether the bridge has tilted.

[0020] The connection component 13 is designed so that the rotation of the bridge base and turntable does not affect the detection of the pressure sensor 11.

[0021] Pressure sensor 11 is a custom size.

[0022] When the force sensor unit 1 on one side is subjected to excessive force and the force sensor unit 1 on the other side is subjected to insufficient force, the bridge tilts, and the tilting direction is towards the direction in which the force sensor unit 1 is subjected to excessive force.

[0023] Preferably, the connecting assembly 13 includes a connecting sleeve 131 fitted onto the detection end of the pressure sensor 11, and the top end of the connecting sleeve 131 is rotatably connected to a connecting ball 132 through a spherical hole.

[0024] In practice, during installation, the connecting ball 132 is supported on the lower surface of the bridge base or the lower surface of the turntable. When the bridge or turntable rotates, the connecting ball 132 also rotates.

[0025] Furthermore, the main board of the display controller 14 is equipped with a synchronization module for controlling the synchronous lifting and lowering of the electric push rod 12.

[0026] In practical implementation, by setting the synchronization module, the display controller 14 can control the telescopic ends of the four electric push rods 12 to extend synchronously to the same height.

[0027] Furthermore, the display controller 14 is equipped with a speaker and an alarm light.

[0028] In practice, when a pressure sensor 11 is subjected to excessive force, the display controller 14 will alert the construction personnel through a speaker and an alarm light, so that the bridge tilts in time and the direction of the tilt can be known through the alarm light.

[0029] Furthermore, the support end at the bottom of the pressure sensor 11 and the telescopic end of the electric push rod 12 are connected by a flange.

[0030] In practice, the pressure sensor 11 and the electric push rod 12 are coaxially assembled using a flange.

[0031] Furthermore, a flange is fixedly connected to the bottom end of the cylinder body of the electric push rod 12.

[0032] In practice, the bottom end of the cylinder of the electric push rod 12 can be fixed to a horizontal ground or to the upper surface of the chassis of the rotating bridge device via a flange.

[0033] Furthermore, the outer wall of the cylinder of the electric push rod 12 is provided with a concave annular groove, the interior of which is filled with a colored liquid, and a sealing ring made of transparent material is provided at the opening of the annular groove. The outer wall of the sealing ring is provided with several equidistant circular scale lines.

[0034] In practice, when the electric push rod 12 tilts, the tilt of the electric push rod 12 can be determined by observing the overlap between the liquid level line of the colored liquid inside the annular groove and the circular scale line.

[0035] Transparent acrylic sheet.

[0036] The colored liquid is a mixture of alcohol, glycerol, ethylene glycol and water.
