Abstract
Disclosed is a distance adjusting device of a low construction trolley frame. Wall plates of the low construction trolley frame are connected through connecting screw rods and nuts. One ends of connecting screw rods are provided with short threads, and wall plates are clamped, fixed and installed on the connecting screw rods through fastening nuts. The other ends of the connecting screw rods are provided with long threads. Positions of adjusting nuts on screw rods can be changed in accordance with distance requirements of rails, another wall plate is clamped through adjusting nuts and fastening locking nuts, the distance of the trolley frame is matched with the rail distance, and convenient installation and adjustment for clients are achieved.
Description
Technical field
The utility model relates to mechanical equipment, especially low building trolley crane trolley frame.
Background technology
Existing low building trolley frame, the spacing of its vehicle frame is to determine according to the data that the client provides, and fixes with bolt or pitman and to fix, and can not regulate according to actual conditions.Before low building dolly was installed, the track of low building dolly installed, because the various errors that occur in processing and the installation process, the spacing of low building trolley frame and track space often are difficult to fully coupling.
If can directly in the spacing of trolley frame adjusted trolley frame, just can make things convenient for the client to install.
Summary of the invention
The purpose of this utility model provides a kind of low building trolley frame spacing adjusting device, its objective is such realization:
The wallboard of low building trolley frame connects by connecting screw mandrel and nut, an end that connects screw mandrel is short thread, by clamp nut board wall is fixedly clamped to be installed in and connects on the screw mandrel, connecting the screw mandrel other end is long screw thread, spacing needs according to track, can change the position of setting nut on screw mandrel, another board wall is clamped with setting nut and fastening locknut, the spacing of low building trolley frame is complementary with the low track space of building dolly, makes things convenient for the client to install and the purpose of regulating thereby reached.
This technical scheme, the track space that has overcome low building dolly just determined before installation by the client and with the deficiency of the difficult coupling of spacing of low building trolley frame, make low building trolley frame structure and field engineering obtain further perfect.
Description of drawings
Fig. 1 is the front elevation of low building dolly;
Fig. 2 is the lateral plan of low building dolly;
Among the figure: 1. be with gear one guide wheel, 2. guide wheel shaft, 3. transmission shaft, 4. shaft gear, 5. wallboard, 6. fastening locknut, 7. setting nut 8. connects screw mandrel, 9. clamp nut, 10. wallboard, 11. clamp nuts, 12. shaft gears, 13. guide wheel shaft, 14. band gear one guide wheels, 15. guide wheels, 16. guide wheel shaft, 17. fastening locknuts, 18. connect screw mandrel.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The band gear one guide wheel 1/14 of low building dolly is installed in orbit, and the spacing of track has determined the spacing of guide wheel 1 with guide wheel 14.Guide wheel 1/4 is fixed on the wallboard 5/10 by guide wheel shaft 2/13.Connecting screw mandrel 8/18 is linked together board wall 5 and board wall 10 with a determining deviation.An end that connects screw mandrel 8 is short thread, board wall is clamped and installed in clamp nut 9 by clamp nut 11 to connect on the screw mandrel 8.Connecting screw mandrel 8 other ends is long screw thread, and according to the spacing needs of track, the position of secured adjusted nut 7 on screw mandrel clamps board wall 5 usefulness setting nuts and fastening locknut 6, so that the spacing meet requirements of board wall 5 and board wall 10 is complementary with track space.
Claims (1)
1. build the trolley frame spacing adjusting device for one kind low, it is characterized in that: the wallboard of low building trolley frame connects by connecting screw mandrel and nut, an end that connects screw mandrel is short thread, by clamp nut board wall is fixedly clamped to be installed in and connects on the screw mandrel, connecting the screw mandrel other end is long screw thread, according to the spacing needs of track, can change the position of setting nut on screw mandrel, another board wall is clamped with setting nut and fastening locknut, make trolley frame spacing and track space coupling.
