Embodiment 1

[0032] Such as figure 1 , figure 2 , image 3 , Figure 5 As shown, in this embodiment, a non-powered comprehensive inspection vehicle and its bogie include an I-shaped frame formed by combining two equalizing beams 1 and an intermediate beam 2, and two rotating beams are arranged below the frame and are respectively located at The rotating shaft 3 on both sides of the middle beam 2, the wheel set 7 arranged on the rotating shaft 3, the axle box 4 arranged at both ends of the rotating shaft 3 and outside the frame, the primary suspension 8 arranged between the axle box 4 and the frame and the arrangement The secondary suspension 5 above the frame, one end of the frame is provided with a mounting beam 6 parallel to the rotating shaft 3, the mounting beam 6 includes a track detection beam or a track inspection beam, and the axle box 4 is provided with There is a detection structure 9 for detecting driving parameters.

[0033] The main function of the track inspection beam i...

Embodiment 2

[0045] Such as Figure 4 , Figure 5 As shown, on the basis of the above embodiments, in this embodiment, the end face connecting the frame and the installation beam 6 is a stepped face 101 . Utilizing the stepped surface 101 increases the bearing capacity of the end face of the frame, and when the installation beam 6 is assembled, the positioning accuracy of the installation beam 6 can be improved, which is conducive to improving the stability of the installation beam 6 after installation.

[0046] In this embodiment, the frame and the installation beam 6 are connected by several M20 bolts. The bolt connection is convenient for assembly, and enables the mounting beam 6 to be detachable for easy replacement. The use of the stepped surface 101 can reduce the shearing force on the bolts and reduce the risk of the bolts loosening and falling off, thereby improving the safety performance, enhancing the bearing capacity of the frame to the installation beam 6 and the bearing capa...

Embodiment 3

[0048] On the basis of the above-mentioned embodiments, in this embodiment, the primary suspension 8 adopts a single coil steel circular spring and a vertical shock absorber; the secondary suspension 5 adopts a rubber stack and a lateral shock absorber. Suspension parameters are properly configured, which improves the running stability of the vehicle and reduces the adverse effects of shock and vibration on the testing equipment. The foundation brake is single-side tread brake, and the unit brake cylinder is arranged horizontally. The brake shoe is a low-friction synthetic brake shoe with a single-sided double-brake shoe structure, which is good for heat dissipation.

[0049] A cylindrical roller bearing used in conjunction with the rotating shaft 3 is arranged in the axle box 4 .

[0050] The installation beam 6 is provided with an anti-off hook. This facilitates hoisting of the entire bogie, and also enables the car body 10 to be connected to the car body 10 through a stee...

Abstract

The invention discloses a power-free comprehensive detection vehicle and a bogie thereof. The vehicle comprises an I-shaped framework, two rotating shafts, wheel pairs, shaft boxes, first suspensionsand second suspensions, wherein the I-shaped framework is formed by the combination of two equalizing beams and a middle beam, the two rotating shafts are rotatably arranged below the framework and positioned on the two sides of the middle beam, the wheel pairs are arranged on the rotating shafts, the shaft boxes are arranged on the two ends of each rotating shaft and positioned on the outer sideof the framework, the first suspensions are arranged between the shaft boxes and the framework, and the second suspensions are arranged above the framework. One end of the framework is provided with amounting beam which is parallel to the rotating shafts, wherein the mounting beam comprises a track detection beam or a track patrolling beam, and each shaft box is provided with a corresponding detection structure used for detecting driving parameters. The power-free comprehensive detection vehicle and the bogie thereof have the beneficial effects that the scheme can provide reliable mounting foundation for track detection or patrolling equipment so as to facilitate the implementation of full line on-line continuous detection, so that workers do not need to enter metro tunnels and other places unfit for the workers to access, and accordingly safety performance during detection can be improved.

Description

technical field [0001] The invention relates to the technical field of inspection vehicles, in particular to a non-powered comprehensive inspection vehicle and its bogie. Background technique [0002] The subway comprehensive inspection vehicle came into being. It is an important tool to ensure the safety, stability and comfort of urban rail vehicles and to guide track maintenance. At present, the track inspection of urban rail lines mainly uses high-precision handheld devices, hand-push trolleys or subway comprehensive inspection vehicles to measure the quality of rails. However, the handheld device can only achieve single-point measurement, and the handheld device or trolley is not suitable for places such as subway tunnels where personnel are not suitable for entry. In addition, the values ​​obtained by these devices for rail quality measurement are extremely unstable, and the data are highly discrete. The main reason is that hand-held devices or trolleys cannot provide ...
