Description

Reference device for leveling monorail vehicle

Technical Field

The utility model belongs to the technical field of rail transit vehicle assembly process, especially, relate to monorail vehicle makes level and uses benchmark device.

Background

At present, the main body of the domestic rail transit vehicle is of a steel wheel structure, the running line is a steel rail with standard gauge of 1435mm, and the rail transit vehicle has mature technology and application experience. The straddle type monorail car (single axle) has no precedent in domestic manufacture and application at present, and no referential mature manufacturing technology exists at present. The monorail vehicle needs to be calibrated after long-term use, and no proper mature technology exists at present.

Disclosure of Invention

The purpose of the invention is as follows: to the problem that above-mentioned current exists and not enough, the utility model aims at providing a monorail vehicle makes level and uses benchmark device carries out benchmark measurement, adjustment vehicle structure size through this platform position of making level, guarantees that vehicle assembly size satisfies design and operation requirement. The monorail leveling platform is simple in design structure, comprehensive in consideration and simple to use and operate.

The technical scheme is as follows: in order to achieve the purpose of the invention, the utility model adopts the technical scheme that: a reference device for leveling a monorail vehicle comprises a bearing main body, a vertical adjusting mechanism and a leveling interface, wherein bearing reference surfaces are respectively arranged at two end parts of the upper end surface of the bearing main body, two measuring reference surfaces are arranged in the middle of the upper end surface of the bearing main body, and the bearing reference surfaces and the measuring reference surfaces are positioned on the same horizontal plane; the vertical adjusting mechanism comprises a plurality of screw rod assemblies arranged in the bearing main body, and the screw rod assemblies are positioned at corresponding positions of the bearing reference surface; the bottom of the bearing main body is fixed with the foundation through a plurality of leveling interfaces.

Preferably, the leveling interface is a support seat provided with an adjusting screw rod.

Preferably, a support for fixing the correction tool is further arranged in the bearing main body, and the support is a support with adjustable vertical height.

Preferably, a hand wheel is connected with the screw rod assembly of the vertical adjusting mechanism.

Preferably, the bracket is provided with a theodolite.

Has the advantages that: compared with the prior art, the utility model discloses a benchmark that platform position set up of making level is measured, the vehicle structure size is adjusted, guarantees that vehicle assembly size satisfies design and operation requirement. The monorail leveling platform is simple in design structure, comprehensive in consideration and simple to use and operate.

Drawings

FIG. 1 is a schematic structural view of a leveling reference device for a monorail vehicle according to the present invention;

FIG. 2 is a front view of the leveling reference device for the monorail vehicle according to the present invention;

FIG. 3 is a partial enlarged view of the structure of the reference device for leveling of the monorail vehicle.

The device comprises a bearing main body 1, a vertical adjusting mechanism 2, a leveling interface 3, a bearing reference surface 3, a measuring reference surface 4, a vertical adjusting mechanism 5, a leveling interface 6, an adjusting screw 7, a support 8 and a hand wheel 9.

Detailed Description

The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.

As shown in fig. 1-3, the utility model discloses a monorail vehicle makes level and uses benchmark device is based on its profile of platform position and the structure reference of making level of monorail car strides sitting posture monorail car orbit and designs, has to stride sitting posture monorail car and walk capable, the bearing function, is applicable to and strides a formula monorail car and makes level the operation and use. The main bearing main part, vertical guiding mechanism and leveling interface of including bearing, the both ends that bear the main part up end are equipped with respectively and bear the reference surface, and the middle part that bears the main part up end is equipped with two measurement reference surfaces, bear the reference surface and be in same horizontal plane with the measurement reference surface, two reference surfaces are as the loading end of vehicle around to guarantee that the vehicle arranges same horizontal plane in, two reference surfaces in middle part are as dimensional measurement's benchmark, are used for measuring, confirm the horizontal position of automobile body, also are theodolite height position correction benchmark simultaneously.

The vertical adjusting mechanism comprises a plurality of screw rod assemblies arranged in the bearing main body and a hand wheel connected with the screw rod assemblies, and the screw rod assemblies are located at corresponding positions of the bearing reference surface. The hand wheel on the side of the platform drives the screw rod to control the adjusting mechanism to move up and down, and the jacking force acts on the cross beam of the bogie to realize the function of horizontally adjusting the bogie.

The bottom of the bearing main body is fixed with the foundation through a plurality of leveling interfaces, and the leveling interfaces realize the adjustment of the levelness of the bearing main body through connecting screws between the leveling interfaces and the supporting seat. The platform position of making level promptly bears the weight of both ends inboard of main part and sets up the support, and the support can be in the vertical direction through rotation adjustment height position for putting and the height correction of theodolite, as the benchmark of ground connection boots installation adjustment.

When in use, the straddle type monorail vehicle is pulled to the leveling platform of the device, and the front and rear traveling wheels of the vehicle are arranged on the bearing reference surface. The vertical adjusting device is driven to move up and down through the hand wheel, and the bogie is adjusted to be in a horizontal position. The height position of the theodolite is adjusted by the support, and the size of the overall structure of the vehicle is measured and adjusted by assisting other measuring tools, so that the size requirement of the vehicle assembly is met.
