Description
Technical field
The present invention relates to technical field of engineering machinery, and in particular to a kind of aerial work platform weighing detection device.
Background technology
Aerial work platform is widely used in the field of operation such as equipment installation, repair and maintenance and high-altitude construction, due to high-altitude
Job platform is for manned equipment, and therefore, security performance is particularly important.Wherein, overload is to cause the weight of safety accident
One of big reason, therefore, the accuracy and validity of the detection that overloads are to ensure that the necessary condition of equipment safety.It is flat in working at height
Platform arm support trails when being worked, in order to which vehicle stabilization is not tumbled, it is necessary to which the loading capacity on real-time monitoring column is to ensure to carry
Weight is in safety work amplitude range.
In the prior art, the weighing detection device generally use pressure type of aerial work platform is weighed testing agency, to ensure
Column load-carrying work without departing from setting permissible value, while to meet EN280 and EN13849 safety standard requirements, the pressure type is weighed
Weighing sensor in testing agency preferably uses double-channel weighing sensor.Weighing detection device may be mounted at working at height
Between the arm support and work column of platform, as shown in Figure 1, the pressure type is weighed, testing agency's primary structure composition includes that binary channels claims
Sensor, first sensor detection plate and second sensor detection plate are retransmitted, the double-channel weighing sensor is mounted on first and passes
Between sensor detection plate and second sensor detection plate as Figure 2-3, the first sensor detection plate is mounted on for connecting
The arm support is connect on the link on the column that works, second detection plate is mounted on work column；The binary channels weighing and sensing
Device is mounted between the first sensor detection plate and second sensor detection plate, and the pressure type weighs testing agency using double
(it is special that the operation principle of double-channel weighing sensor can refer to Chinese utility model for the load-carrying on channel weighing sensor detection work column
Description in sharp CN203069242U).By being demarcated respectively to the AD values (i.e. analog value) in two channels in program,
The current value in two channels is compared after calibration again, if the difference of two current values exceeds setting range, then can prompt weighing and sensing
The comparison mistake of device, and then limit corresponding actions.However, the test side due to double-channel weighing sensor is examined with second sensor
It is " point-face " contact between drafting board, and typically being in direct contact between ironware and ironware so that its frictional force is larger, and lubricity is not
Enough, this will cause double-channel weighing sensor the comparison mistake between two channels often occur.Specifically as shown in figure 4, when weight
Object is influenced after A points are transferred to B (or C) points by work column structure, and using test point as the center of circle one small angle will occur for work column
The rotation of degree, along the directions AB and AC respectively to sensor test point generate a lateral force, cause two channels actual value it
Difference is larger, may exceed setting value K (K values are the parameter that establishing criteria required and be actually needed setting), cause sensor
Compare false alarm；And after weight moves to A points from B (or C) points, due to the presence of frictional force, the lateral force in the direction AB, AC is not
It can eliminate in time, cause the difference of the actual value in two channels that cannot eliminate in time, it is possible to setting value can be exceeded, can equally draw
Send out the comparison false alarm of sensor.
Based on this, it is necessary to be improved to the weighing detection device structure of existing aerial work platform, to promote operation
The stability of platform load-carrying detection.
