Abstract

The utility model relates to a railcar and belongs to the technical field of engineering equipment. The railcar comprises a frame which is provided with a net plate; four corners of the frame are provided with supporting parts; wheel groups which can rotate independently are symmetrically arranged at the bottom of the frame; the rotatable wheel groups are formed by wheel frames, rotating shafts and wheels; the rotating shafts are fixed on the wheel frames respectively and rotate along the horizontal direction; the wheels are connected onto the wheel frames respectively. The frame of the railcar is smoothly supported through the supporting parts, the wheels are separated from the frame through the rotatable wheel groups under the action of the gravity, the weights of the wheels are pressed on thrust ball bearings which are arranged on the frame, the wheel groups rotate, and accordingly the steering of the wheels is achieved. According to the railcar, the structure is simple, the operation is simple and convenient, the use is safe and reliable, the production site can be saved, and the rail can be popularized in steel structure workshops and can also be popularized in other construction machinery industries.

Description

A kind of small rail car
Technical field
The utility model relates to a kind of rail vehicle, belongs to engineering equipment technical field.
Background technology
In steel structure workshop, need to utilize rail vehicle to transport, mainly there is following problem in existing small rail car:
1, steel structure processing place, material or member need to transport by small rail car between job shop, sandblast paint shop and outdoor place, and track must be arranged vertically, and just can make small rail car in processing place circular flow.If small rail car is turned, need very large turn radius to realize, limited by place, steel structure processing place cannot provide the turning place of small rail car.
2, traditional small rail car operation needs the very large melt pit that turns to, and shifts small rail car onto melt pit place and turns to the rear small rail car circular flow that just can make.Turn to by the dolly on melt pit, need a very large place, and the distance of small rail car implementation,, also there is potential safety hazard in complicated operation.
Utility model content
The purpose of this utility model is in order to address the deficiencies of the prior art, and a kind of small rail car is provided, and saves production site.
In order to achieve the above object, the utility model is taked following technical scheme: a kind of small rail car, comprise vehicle frame, on described vehicle frame, web plate is installed, four angles place of described vehicle frame is provided with strut member, the rotatable wheel group of described bottom of frame symmetrical placement, described rotatable wheel group, by vehicle wheel frame, is fixed on the rotating shaft of the along continuous straight runs rotation on vehicle wheel frame and is connected to the wheel composition on vehicle wheel frame.Support reposefully the vehicle frame of small rail car by strut member, rotatable wheel group is under Action of Gravity Field, and wheel separates with vehicle frame, the weight of wheel be pressed on vehicle frame thrust ball bearing on, rotating vehicle wheels, complete turning to of wheel.
Wherein, described vehicle wheel frame top is provided with the first steel plate, described rotating shaft is positioned at the center of the first steel plate, described bottom of frame welding second steel plate corresponding with the first steel plate position, the center of described the second steel plate is provided with hole, described rotating shaft, through hole, is socketed thrust ball bearing and bearing block, fixed type bearing lid in described rotating shaft in rotating shaft.Described bearing block is annular arrangement, is placed in thrust ball bearing periphery.Described bearing cap shim is fixed in rotating shaft by bearing pin.
Of the present utility model simple in structure, easy and simple to handle, safe and reliable, the more important thing is and can save production site.Not only can promote in steel structure workshop, can also on Other Engineering machinery industry, promote.

Detailed description of the invention
Embodiment
The structure of the present embodiment as shown in Figures 1 to 4, a kind of small rail car, comprise oblong vehicle frame 1, support body adopts shaped steel 4, and web plate 5 is installed on vehicle frame 1, and web plate 5 is steel plate web plate, four angles place at vehicle frame 1 is provided with strut member 3, the rotatable wheel group 2 of vehicle frame 1 bottom symmetrical placement, rotatable wheel group, by vehicle wheel frame 13, is fixed on the rotating shaft 16 of the along continuous straight runs rotation on vehicle wheel frame 13 and the wheel 11 being connected on vehicle wheel frame and forms.Wheel 11 is fixed on vehicle wheel frame 13 by axle 12.Vehicle wheel frame top is provided with the first steel plate 14, rotating shaft 16 is positioned at the first steel plate 14 center, the second steel plate 15 that vehicle frame 1 bottom welding is corresponding with the first steel plate 14 positions, the second steel plate 15 center is provided with hole 21, rotating shaft 16 is through hole 21, in rotating shaft 16, be socketed thrust ball bearing 20 and bearing block 18, fixed type bearing lid 17 in rotating shaft 16.Bearing block 18 is annular arrangement, is placed in thrust ball bearing 20 peripheries.Bearing cap shim 17 is fixed in rotating shaft 16 by bearing pin 19.Support reposefully the vehicle frame 1 of small rail car by strut member 3, rotatable wheel group is under Action of Gravity Field, and wheel separates with vehicle frame, the weight of wheel be pressed on vehicle frame thrust ball bearing on, rotating vehicle wheels, complete turning to of wheel.
When work, first small rail car is put on one group of parallel track, promote dolly to vertical track position, road, support the bracing frame of vehicle frame surrounding, wheel supporting is arrived to the position slightly higher than track, rotatable wheel group is under Action of Gravity Field, wheel group separates with vehicle body, bearing cap shim is just in time being pressed onto on thrust ball bearing, steel plate with separate certain gap, rotating vehicle wheels, wheel group is aimed to the vertical track in below, unclamp strut member, car wheel is dropped on vertical track, completed turning to of small rail car.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
