Indoor test detector for wind-resistant anti-slip brake of port crane

Abstract

The invention discloses an indoor test detector for a wind-resistant anti-slip brake of a port crane, which comprises a base platform, a test bed frame, vertical loading cylinders, a gravity transfer box, a bogie frame, a wheel set, a steel rail and a horizontal thrust cylinder, wherein the vertical loading cylinders are fixed below a beam, the lower ends of the vertical loading cylinders are connected with the gravity transfer box, the lower end of the gravity transfer box is connected with the middle of the upper portion of the bogie frame through a hinged shaft, and the horizontal thrust cylinder is mounted on the base platform, is positioned on one side of the test bed frame and is connected to the bottom of the middle of the bogie frame through a horizontal push rod. The indoor test detector is capable of simulating wheel pressure and the horizontal force borne by the bogie frame indoors under the action of movement bearing and wind load of the port crane, and is capable of simultaneously detecting wind-resistant anti-slip capacity of wind-resistant anti-slip brake series products of the port crane, and the indoor test detector has the advantages of accuracy in test and simplicity and convenience in operation.

Description

technical field [0001] The invention relates to a test and detection device for a wind-resistant and anti-skid brake of a port crane, in particular to a wind-resistant and anti-skid brake for a port crane (electric hydraulic type wind-resistant iron wedge brake and hydraulic wheel side brake and hydraulic top rail device, rail clamping device) device) indoor test detection device. Background technique [0002] Under the action of strong gusts or strong storms, port cranes will cause the wheels of the entire crane cart to move along the direction of the track. Once the wheels slip and roll and the crane moves, the crane will derail, overturn and other serious personal and property casualties. In recent years, new electro-hydraulic windproof iron wedge brakes (referred to as windproof iron wedge brakes), hydraulic wheel side brakes (referred to as wheel side brakes) and hydraulic top rail devices have been installed on the trolley group of the port crane trolley operating mech...

AI Technical Summary

Problems solved by technology

Due to the high size of port cranes, manufacturers of windproof iron wedge brakes and wheel brakes and port users have done some port field tests, that is, using large traction vehicles to tow the entire crane (windproof iron wedge brake wedge top wharf track When the wheel is clamped by the surface or wheel brake), until the wheel of the crane cart slips, and then the tension sensor is used to detect and calculate the magnitude of the wheel slip force caused by the crane's own weight wheel pressure, but it cannot be carried out in strong gusts or strong storms On-the-spot detection test of crane's anti-wind and anti-skid ability under active conditions

At present, the manufacturer lacks a special test device for indoor inspection of the performance of windproof iron wedge brakes and wheel brakes, as well as hydraulic top rail devices and rail clamps.
