Technical field
Hoisting and conveying machinery and equipment technical field is the utility model is related to, especially a kind of anti-formula crane wheel load of crossing is surveyed
Trial assembly is put.
Background technology
At present, the main method for the test of crane wheel load is the placement force sensor on jack, then with thousand
The supporting leg of jin jack-up crane, reads the reading of pressure sensor, then divides pressure on each wheel equally, and then calculate wheel
Pressure.This method testing efficiency is low, and equipment is heavy, and is held up the pressure on supporting leg to be divided equally on each wheel to obtained wheel
Difference is larger.Another method is stickup foil gauge in orbit, and then crane wheel crosses the track for being pasted with foil gauge,
Wheel load is calculated according to strain time history figure.This method is because before strain gauge adhesion, track is because the effect of crane
There can be the strain of a part, the strain can be initialised in the feelings of test.Additionally due to the reason such as mismachining tolerance, crane
Wheel is not straight down to the pressure of track, it is possible to has the moment of flexure of part, influence of the moment of flexure to strain can not
Eliminate.
Utility model content
The applicant be directed to above-mentioned existing production technology in wheel load testing efficiency is low, equipment is heavy, various extraneous errors without
The shortcomings of method eliminates, there is provided it is a kind of it is rational in infrastructure it is anti-cross formula crane wheel compression testing device, so as to quickly to wheel
Pressure is tested, it is not necessary to bulky equipment, and various extraneous errors can be eliminated.
Technical scheme is as follows used by the utility model：
One kind is anti-to cross formula crane wheel compression testing device, including pressure sensor, one end peace of the pressure sensor
Equipped with extradition structure, the other end of the pressure sensor, which is provided with, to be prevented crossing device, and the anti-inner side for crossing device is anti-
Face is crossed, the anti-rear end for crossing device is data collecting system；The upper surface of the pressure sensor is provided with groove, described
Bogey is installed in groove, the upper surface of the bogey is loading end, the loading end and pressure sensor it is upper
Flush.
Further improvement as above-mentioned technical proposal：
The extradition knot forms triangular structure, and the upper surface of the extradition structure is slope, and the angle on the slope is
0°-45°。
The angle on slope is 15 °.
Anti- to cross face into arc structure, the radius of the circular arc is 125mm-450mm.
The gross thickness of the pressure sensor is less than or equal to 50mm.
Pressure sensor is single-sensor or dual sensor
The beneficial effects of the utility model are as follows：
The utility model is compact-sized, reasonable, easy to operate, by the effect of pressure sensor, by the wheel of crane
When tread is moved to loading end, you can carry out display test result by data collecting system.
The utility model device is light and handy, conveniently installs and easy to carry, on the track of crane, cost
It is low.
The utility model test is simple, without numerous and diverse operating process.
The utility model measuring accuracy is high, can correct the extraneous error brought automatically.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.
As depicted in figs. 1 and 2, the anti-of the present embodiment crosses formula crane wheel compression testing device, including pressure sensor 3,
One end of pressure sensor 3 is provided with extradition structure 1, and the other end of pressure sensor 3, which is provided with, to be prevented crossing device 5, anti-to cross
Face 4 is crossed in the inner side of device 5 to be anti-, and the anti-rear end for crossing device 5 is data collecting system 6；Open the upper surface of pressure sensor 3
It is fluted, bogey is installed, the upper surface of bogey is loading end 2, loading end 2 and pressure sensor 3 in groove
Upper surface is concordant.
Structure 1 is extradited into triangular structure, the upper surface of extradition structure 1 is slope, and the angle on slope is 0 ° -45 °.
The angle on slope is 15 °.
Anti- to cross face 4 into arc structure, the radius of circular arc is 125mm-450mm.
The gross thickness of pressure sensor 3 is less than or equal to 50mm.The design of angle and thickness, so that crane wheel 7 is easy to
Press through sensor.
As shown in Figure 3 and Figure 4, pressure sensor 3 is placed on track 8, one end of pressure sensor 3 sets certain slope
Degree, facilitates crane to drive into sensor top；
The other end of pressure sensor 3, which is set, stops version, prevents crane from crossing sensor.
