Abstract
The utility model discloses a combined wheel set device which is a constituent element of a track checker. The utility model essentially comprises a wheel set bracket, transport wheels, a meter wheel, a guide wheel, insulation protective components of the meter wheel and the directive wheel, and so on. The transport wheels are arranged between the two side support arms of the wheel set bracket through a shaft, the axial lines of the transport wheels and the wheel set bracket are arranged in parallel with the installing plane on a vertical crossbeam, the meter wheel and the guide wheel are perpendicular to the installing surface of the wheel set bracket along the axial lines and arranged on the lower end face of one side support arm. The combinatory wheel set device solves the problems of not very high measurement precision caused by the insufficient assembly accuracy of the meter wheel and the transport wheels and the fat edges and side grinding of rails, and inconvenient processing and dismounting, and so on.
Description
Technical field
The utility model relates to railroad track somascope technical field, more particularly relates to constitute parts that comprise road wheel, meter wheel and directive wheel of track somascope.
Background technology
The track somascope is in promoting the lower edge track travel process that enforcement is measured to orbit parameter, except the needs road wheel is close to the walking of rail surface, for locate and measure gauge, rail to etc. parameter, also need meter wheel to be close to the medial surface of rail, simultaneously meter wheel is all had very high required precision at the laminating points of rail medial surface apart from the distance of rail level and the two-wheeled axis verticality between road wheel and the meter wheel.In addition, meter wheel also had insulating requirements.In the prior art, road wheel and meter wheel normally independently are installed on the longitudinal and cross beam respectively separately, or they are carried out being installed in after the simple combination in length and breadth on the beam, road wheel and meter wheel are installed in this mode of beam in length and breadth, the place of its deficiency, be to be difficult to guarantee the fitted position precision on the one hand, and then influence the orbital-elements measurement precision; Be the fat edges and the side grinding of rail on the other hand, certainty of measurement and normal operation are also had a negative impact; Besides, when the rail gap that forms when track bond was big, rail gap can form bigger impact to meter wheel, cause meter wheel and complete machine to damage, and rail gap also may block meter wheel, causes measure error.There are problems such as dismounting inconvenience in addition.
Summary of the invention
Above-mentioned defective at prior art, the purpose of this utility model aims to provide a kind of road wheel and the meter wheel assembly precision is guaranteed, is not subjected to the limitation of rail lip or side grinding, the certainty of measurement height, be convenient to simultaneously processing again, the novel combination type Wheels group arrangement of easy accessibility.
Above-mentioned purpose of the present utility model can realize by the track detector combined type Wheels group arrangement with following technical scheme.
The track detector combined type Wheels group arrangement that the utility model discloses, mainly comprise wheel pack support, road wheel, meter wheel and directive wheel, road wheel is installed between the both sides support arm of wheel pack support by axle, its axis is parallel with the installed surface that the wheel pack support is installed on the beam in length and breadth, meter wheel and directive wheel axis perpendicular to the lower end that is installed in a side stand arm with taking turns the pack support installed surface, to guarantee making road wheel be close to the walking of rail upper surface, meter wheel is close to the medial surface of rail.
In technique scheme, described directive wheel and meter wheel preferably are installed on the lower surface of a side stand arm by bearing pin pair and fixture.
In technique scheme, described meter wheel and directive wheel, its axis preferably is positioned at same vertical guide.
In technique scheme, the directive wheel of described Wheels group arrangement is two.Can certainly be set to one or, preferably be set to two more than two.The set-up mode of directive wheel is two or more than two, directive wheel is arranged on the meter wheel both sides for directive wheel, no matter so that the track somascope walks forward or walking backward, it is the meter wheel guiding that directive wheel is all arranged.
In technique scheme, the below of directive wheel and meter wheel is provided with the insulating protection member, so that the track somascope is protected directive wheel and meter wheel in measuring walking process, avoids being damaged by collision.General with the insulating protection member of a bar blocks as meter wheel and directive wheel, be installed in directive wheel and meter wheel and install on the downward end of bearing pin.The material of bar blocks is generally hard macromolecular materials such as pottery or polytetrafluoroethylene (PTFE).
In technique scheme, the wheel pack support of Wheels group arrangement is an overall structure, and the specific constructive form of monolithic wheel pack support can be " U " font of symmetry, also can be asymmetric " U " font.The wheel pack support is the main body of Wheels group arrangement, and travelling wheel, meter wheel and directive wheel all are installed on it, and can also on a side stand arm odometer sensor be installed as required simultaneously.
The track detector combined type Wheels group arrangement that the utility model discloses, meter wheel compared to prior art and road wheel are installed in the mode on the beam in length and breadth, have following good effect:
1, the overall structure of the wheel pack support of Wheels group arrangement, make Wheels group arrangement whole to install and remove, thereby the assembly precision between meter wheel and the road wheel is guaranteed, and avoided having improved the orbital-elements measurement precision because rail gap blocks measure error that meter wheel causes.
2, the overall structure of the wheel pack support of Wheels group arrangement greatly reduces the impact that rail gap forms meter wheel, and meter wheel and directive wheel below is provided with the insulation protection member in addition, and meter wheel and complete machine spoilage greatly reduce.
3, the track detector combined type Wheels group arrangement of the utility model announcement, be equipped with applicant's meter wheel of application in addition again, can avoid the fat edges of rail and side grinding to the adverse effect that certainty of measurement and normal operation produce fully, further improve the reliability of certainty of measurement and operation.
4, because the meter wheel both sides are equipped with directive wheel, therefore can satisfy the needs that track detector advances and retreats use.
5, because meter wheel and directive wheel can be dismantled separately again on the wheel pack support, so their replacing is very convenient.
The utility model also has some advantages of others.
