A circular plate type weighing sensor is arranged between the beam and the steel pipe pile, and is fixed on the steel pipe pile through bolts or welding; the barrier gate system is arranged between the second span and the first span of the bridge deck of the steel trestle, and a lifting rod is arranged on the barrier gate system in the middle of the width direction of the steel trestle; the barrier gate system comprises a lifting rod executing mechanism, a controller and a display; the circular plate type weighing sensor is connected with a controller of the barrier gate system, and the controller is respectively connected with the display and the lifting rod executing mechanism; the lifting rod executing mechanism executes whether the barrier lifting rod is lifted or not according to the signal of the controller.
The steel trestle is divided into double roads by the road gate system, the right side of the steel trestle enters the road gate system, and the vehicle needs to stop and weigh; when the left side is driven out and the vehicle is driven out of the steel trestle, the barrier gate lifting rod is automatically lifted.
The utility model has the beneficial effects that the traditional wagon balance system can be replaced by adding the bearing sensor and the road gate system on the original common steel trestle. The utility model has the advantages of clear principle and relatively simple operation, and can effectively prevent heavy equipment from being overloaded when the heavy equipment is on an upper bridge, thereby improving the construction safety. Meanwhile, the method can also obviously reduce the cost and bring economic benefit to construction projects.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
The steel trestle consists of a steel trestle bridge deck, a steel trestle guardrail 1, steel pipe piles 5, a parallel connection 4, a bailey beam 3 and a cross beam 8; the cross beam 8 is arranged on the steel pipe piles 5, and the steel pipe piles 5 are fixedly connected by adopting the parallel connection 4; the steel trestle bridge deck is arranged on the cross beam 8 through the bailey beam 3; and steel trestle guardrails 1 are arranged on two sides of the steel trestle bridge deck in the length direction.
The embodiment relates to a steel trestle weighing system for construction, its construction process is:
(1) As shown in fig. 1, the disc-type load cell 2 is a sensor commonly used for measuring weight, which is installed between the steel pipe pile 5 and the cross member 8, and the weight of a placed vehicle or equipment can be determined by measuring the pressure on the cross member. In order to ensure accuracy and stability, the circular plate type load cell 2 needs to be fixed to the steel pipe pile 5 by bolting or welding to avoid movement or sway.
(2) The barrier system 6 of this embodiment includes a lifter actuator, a controller, and a display. The circular plate type weighing sensor 2 is connected with a controller through a cable, and the controller is respectively connected with a display and a lifting rod executing mechanism through cables. The display can display the weight of weighing, the green light is displayed according with the weight requirement, and the lifting rod 7 is lifted by the lifting rod executing mechanism to release the vehicle; and displaying a red light for overweight, and refusing the traffic of the vehicle.
The cable is placed in the wire groove of steel landing stage, and protection cable is prevented from the vehicle rolling.
(3) As shown in fig. 2, the barrier system 6 is a device installed between the first span and the second span of the steel trestle for controlling the passage of vehicles or equipment. In order to meet the requirements of various vehicles, cranes, etc., the first span needs to be long enough, typically 15 meters. This ensures that these vehicles and equipment have sufficient space on the steel trestle for weighing operations and pass under the control of the road gate system.
(4) After installing the barrier system 6 on the steel trestle, the steel trestle may be divided into double walkways to manage and control the ingress and egress of vehicles, as shown in fig. 2. The right lane is dedicated to the direction of travel into the steel trestle, while the left lane is dedicated to the direction of travel into the steel trestle. Such a division may provide an orderly traffic flow and ensure the safety and efficiency of the entry and exit processes. The weighing operation is needed for the vehicles driving into the steel trestle, and on the contrary, the weighing operation is not needed for the vehicles driving into the steel trestle, and when the system detects that the vehicles are driving out of the steel trestle, the road gate system can automatically lift the lifting rod.
(5) As shown in fig. 2, when vehicles, cranes, etc. are driven into a steel trestle, they need to stop before the road gate waiting for a weighing operation. At the moment, the circular plate type weighing sensor starts to work, and converts a weight signal of equipment driven into a trestle into electric quantity and sends the electric quantity to the controller; the controller is responsible for receiving and processing the signals of the sensor; according to weight data of the circular plate type weighing sensor, the controller can judge whether the equipment is overloaded or not through a built-in weight standard; if the equipment is overloaded, the controller can trigger an alarm, the display displays a red light, and the lifting rod of the barrier gate system is forbidden to lift. Conversely, if the device is not overloaded, the display displays a green light, and the bar lift lever will rise, allowing the device to pass. Thus, the control and safe passing of the equipment load on the steel trestle can be ensured.
