Abstract

The utility model discloses an adjustable wheel set for a tunnel shield crane. The adjustable wheel set is arranged on a wallboard of a driving end, comprises a wheel and a wheel installation shaft, and is characterized by also comprising an adjusting seat, a locking nut and a positioning screw, wherein one end of the wheel installation shaft is connected with the wheel, the other end of the wheel installation shaft sequentially penetrates through the wallboard of the driving end and the adjusting seat and is fixed through the locking nut, and the positioning screw penetrates through the top end of the wallboard of the driving end and extends downwards to reach a positioning groove on the top of the adjusting seat. The adjustable wheel set has the advantages that the times for clearing the dust on a track can be reduced by adjusting the distance between the wheel and a gear, an effect that the track is unnecessary to clear can be even realized, the workload can also be alleviated, and the working cost can be reduced.

Description

Tunneling shield hoisting crane adustable wheel group
Technical field
the utility model relates to a kind of adustable wheel group, especially a kind of tunneling shield hoisting crane adustable wheel group.
Background technology
in prior art, the wheel of conventional tunneling shield hoisting crane drive side adopts traditional form, be that wheel is directly fixedly mounted on drive end wallboard, after design typification, the driven wheel center of this version and the distance of wheel center are no longer variable, thereby the spacing of chain and gear is also no longer variable afterwards in installation location.Yet due to work under bad environment in tunnel, dust amount is large, after hoisting crane work a period of time, crane wheel and raceway surface are stained with dust and the spacing of chain and gear are diminished gradually, if clear up not in time the dust of wheel and raceway surface, gear easily and chain generation jam even damage phenomenon, yet the dust of clearing up track and wheel surface in tunnel is a job of wasting time and energy very much.
Summary of the invention
the utility model object is: provide a kind of simple in structure, and even do not use the tunneling shield hoisting crane adustable wheel group of cleaning track for reducing the number of times of cleaning track.
the technical solution of the utility model is: a kind of tunneling shield hoisting crane adustable wheel group, be located on drive end wallboard, comprise wheel and wheel installation shaft, it is characterized in that, also comprise adjustment seat, jam nut and fixing screw, described wheel installation shaft one end is connected with described wheel, its other end is successively through described drive end wallboard and described adjustment seat, and fix by described jam nut, described fixing screw passes described drive end wallboard top and extends downwardly on the positioning groove at described adjustment seat top; According to actual conditions, regulate the position of fixing screw and adjustment seat, adustable wheel group is reached tight a bolt after ideal effect group, thereby the number of times that reduces cleaning track is even with clearing up track.
preferably, described adjustment seat is fixed on described drive end wallboard by bolt group.
preferably, described adjustment seat is provided with the mounting hole matching with described bolt group, and described mounting hole is oval mounting hole.
preferably, between described jam nut and described adjustment seat, be also provided with the packing ring matching with described wheel installation shaft.
preferably, described drive end wallboard is inverted L shape drive end wallboard.
the utility model has the advantages that: by regulating the distance between wheel and gear to reach the number of times that reduces cleaning track dust, even reach the effect that need not clear up track, can also alleviate work capacity, reduce job costs simultaneously.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the utility model cutaway view;
fig. 2 is the utility model structural representation;
wherein: 1 wheel, 2 wheel installation shaft, 3 adjustment seats, 4 jam nuts, 5 fixing screws, 6 inverted L shape drive end wallboards, 7 bolt groups.
The specific embodiment
embodiment: with reference to Fig. 1, shown in 2, a kind of tunneling shield hoisting crane adustable wheel group, comprise wheel 1, wheel installation shaft 2, adjustment seat 3, jam nut 4 and fixing screw 5, this adustable wheel is mounted on inverted L shape drive end wallboard 6, wheel installation shaft 2 one end are connected with wheel 1, its other end is successively through inverted L shape drive end wallboard 6 and adjustment seat 3, and fixing by jam nut 4, fixing screw 5 passes inverted L shape drive end wallboard 6 tops and extends downwardly on the positioning groove at adjustment seat 3 tops, adjustment seat 3 is fixed on inverted L shape drive end wallboard 6 by bolt group 7, adjustment seat 3 is provided with the mounting hole matching with bolt group 7, mounting hole is oval mounting hole, between jam nut 4 and adjustment seat 3, be also provided with the packing ring matching with wheel installation shaft 2.
shown in Fig. 1,2, the utility model is in specific operation process, when piling up dust diminishing between the spacing of chain and gear be because of wheel and track, unclamp bolt group 7, then according to actual conditions, regulate the position of fixing screw 5 and adjustment seat 3, make the spacing of chain and the gear group 7 of recovering to tight a bolt after original value, thereby the number of times that reduces cleaning track is even with cleaning track.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications of doing according to the Spirit Essence of the utility model main technical schemes, within all should being encompassed in protection domain of the present utility model.
