Abstract
The invention discloses a vehicle body steel structural distortion detection tool. The detection tool is composed of two tool units and cushion blocks; a pin assembly is arranged at the center of a split head in each tool unit; the pin assembly comprises a round bar and a round pin; side bearings are arranged at the two sides of the split head; the surface of the round bar of the pin assembly is higher than the upper surfaces of the side bearings; the cushion blocks are arranged on the side bearings of the too units and are used for detecting the distortional degree; and the thickness of each cushion block is equal to the distance between an air spring cushion plate and the side bearings. The detection by utilizing the tool is accurate and simple, and the operability is strong, thus the detected data are truer and more accurate; and accurate distortional data have important significance on the traveling safety of buses on tracks.
Description
Technical field
The invention belongs to trolley coach steel structure of car body technical field, relate to the steel structure of car body distortion and detect.
Background technology
For all kinds trolley coach; Car body all inevitably produces distortion in the steel construction production run; And in the manufacture process of present domestic various subway cars, the detection scheme of use is to use line to weigh down the verticality of measuring 4 parallactic angles of car body, and these verticality data promptly reflect the car body degreeof tortuosity.If but there is distortion in steel construction, after steel construction is fallen bogie so owing on the bogie air spring is arranged, vehicle body can about freely tilt.And in the process that this scheme is measured, a "A" end of car of steel construction all drops on the split heads, and vehicle body can't freely twist, and so just can't simulate steel construction and drop on the virtual condition on the bogie, can the accuracy that the car body distortion detects be impacted.
Summary of the invention
The purpose of this invention is to provide a kind of frock and method of accurate detection steel structure of car body degreeof tortuosity, be convenient to adjust degreeof tortuosity, make steel structure of car body satisfy request for utilization.
For realizing above-mentioned purpose; The present invention provides a kind of steel structure of car body distortion to detect frock; It is characterized in that: form by two frock unit and cushion block; Each frock unit is pin to be set at the center of split heads form; Pin is formed and is comprised pole and round pin, and the split heads both sides are provided with side bearing, and the pole surface that pin is formed is higher than the upper surface of side bearing; Cushion block is arranged on when being used to detect degreeof tortuosity on the side bearing of frock unit and uses, and the thickness of cushion block equals the distance between air spring backing plate and the side bearing.
A kind of steel structure of car body distortion detection method is characterized in that comprising the following steps:
1, before and after vehicle commander's degree direction, moves the pin composition, make and sell the distance that the distance of forming equals steel structure of car body underframe centrepin backing plate on two frock unit;
2, on the side bearing of frock unit at one end cushion block is set; The car that falls then makes the underframe centrepin backing plate of steel structure of car body one end be pressed in the pole surface that pin is formed, and chassis air spring backing plate surface is unsettled with side bearing; Be free end, the other end drops on and is stiff end on the cushion block;
3, use line to weigh down the verticality of measuring steel structure of car body free end both sides respectively, this verticality promptly reflects the degreeof tortuosity of this end car body;
4, remove on the side bearing that cushion block is placed on other end frock unit, same method is measured the verticality of these free end both sides, and this verticality promptly reflects the degreeof tortuosity of this end car body.
The present invention forms by pin; Can simulate the car body state on bogie,, realize measurement accurate, simple, strong operability for the structure of complicacy; Therefore it is true more, accurate to record data, and twisting data accurately will have significance to the driving safety of trolley coach.

Fig. 2 is a stiff end view of the present invention;
Fig. 3 is that pin is formed structural representation;
Fig. 4 is Fig. 3 side-looking enlarged drawing.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4; Frock of the present invention is made up of two frock unit and cushion block 5, and each frock unit is pin to be set at the center of split heads 3 form 1, and pin is formed and comprised pole 101 and round pin 102; The split heads both sides are provided with side bearing 2, and the pole surface that pin is formed is higher than the upper surface of side bearing; Cushion block is arranged on the side bearing of frock unit, and the thickness of cushion block equals the distance between air spring backing plate and the side bearing.
Detection method is following:
1, before and after vehicle commander's degree direction, moves the pin composition, make and sell the distance that the distance of forming equals steel structure of car body underframe centrepin backing plate on two frock unit;
2, on the side bearing of frock unit at one end cushion block is set; The car that falls then makes the underframe centrepin backing plate of steel structure of car body one end be pressed in the pole surface that pin is formed, and chassis air spring backing plate surface is unsettled with side bearing; Be free end, the other end drops on and is stiff end on the cushion block;
3, use line to weigh down 4 verticality of measuring steel structure of car body free end both sides respectively, this verticality A, B promptly reflect the degreeof tortuosity of this end steel structure of car body;
4, remove on the side bearing that cushion block is placed on other end frock unit, use the same method and measure the verticality of these free end both sides, this verticality promptly reflects the degreeof tortuosity of this end car body.
Claims (2)
