Embodiment 1

[0028] Embodiment 1: Detect rail vehicle deceleration roof

[0029] Such as Figure 1-8As shown, the hoist 1 is set at the highest point of the acceleration slope section 301, the wheel sensor 7 is set at an appropriate position in the middle of the acceleration slope section 301, the steel wire rope of the hoist machine 1 is connected to the test vehicle 2 through the traction buffer 6, and the deceleration top under test is installed. The jig 5 is arranged on the flat slope section 302 of the track. The tested decelerator 801 is fixed on the middle part of the rail of the track flat slope section 302 through the installation bolt 803 and the fastening nut 804, and the decelerator installation fixture 5 is clamped on the outside of the decelerator housing 802 by the semicircular clamp 511 and the fastening bolt 512. A pressure sensor 501 and a displacement sensor 506 are provided on the deceleration top installation jig. The sensor cover 502 of the pressure sensor 501 is loc...

Embodiment 2

[0033] Example 2: Detection of rail vehicle parkers

[0034] Such as Figure 9 As shown, when the braking ability of the rail vehicle parking device 9 needs to be detected, the rail vehicle parking device 9 to be tested is installed on the flat slope section 302 of the detection line, and a group is respectively installed at the entrance and the exit of the rail vehicle parking device 9 The speed sensor 4 respectively detects the entrance speed and exit speed of the test vehicle 2 passing through the rail vehicle parking device 9, and the braking capacity of the rail vehicle parking device 9 under test can be obtained through calculation.

Embodiment 3

[0035] Embodiment 3: detect rail vehicle stopper

[0036] Such as Figure 10 As shown, when the braking capability of the rail vehicle stopper 10 needs to be detected, the tested rail vehicle stopper 10 is installed on the flat slope section 302 of the detection line, and a group of speed sensors are installed at the entrance of the rail vehicle stopper 10 4. Detect the speed before the test vehicle 2 collides with the stopper 10 of the rail vehicle. When the rail vehicle stopper 10 is hit by the test vehicle 2, it will slide along the rail, and the braking capacity of the rail vehicle stopper 10 can be calculated by measuring the sliding distance.

Abstract

The invention provides a detection line for railway vehicle speed-reducing equipment. The detection line consists of a windlass, a traction buffer, a testing vehicle, a wheel sensor, a speed sensor, a pressure sensor, a displacement sensor, a detected equipment assembly clamp, an industrial control computer and a rail with an accelerating slope, a flat slope and a speed-reducing slope. The testing vehicle is rolled by using rail height difference, the position of the wheel sensor is changed, and the power supply of the windlass is cut off in time, so that different rolling speeds of the testing vehicle can be obtained. Technical data of the tested equipment can be acquired by various sensors, and a detection result is output through computer operation by utilizing special software. The detection line can detect and record the comprehensive performance of various types of railway vehicle speed-reducing equipment, and can replace the traditional detecting method of pushing trucks by virtue of the railway vehicle or locomotive.

Description

technical field [0001] The invention relates to a detection line for rail vehicle deceleration equipment, and belongs to the technical field of performance detection of rail transit deceleration equipment. Background technique [0002] Currently widely used rail vehicle deceleration equipment, including rail vehicle deceleration roof, rail vehicle parking device, rail vehicle stop device, rail vehicle anti-slip device, reducer emergency protection device and so on. Before leaving the factory, these equipments must carry out a comprehensive performance test of various technical indicators, such as braking power, critical speed, vertical reaction force, braking capacity and so on. The traditional detection method is to use railway railcars to push flatbed trucks on special railway lines. This traditional detection method has very strict requirements on the speed of the rail car, especially when detecting the critical speed, the allowable error of the vehicle speed is only 0.1...
