Description
Technical field
The utility model belongs to oil equipment technical field, relates to a kind of adjustable gap bridge ladder.
Background technology
Oil-well rig causes the installation site of parts different due to the models of equipment such as supporting diesel engine, joint operating device, slush pump and the difference of producer, and the short transverse causing equipment room shaft coupling to be installed and width size change.Therefore, as realize shaft coupling place function of safety protection simultaneously the double gap bridge ladder doing ladder effect must adjust with the pattern of shaft coupling and installation site, cause gap bridge ladder structure similar, but of a great variety, and excessively take up room during transport.
If gap bridge ladder all can regulate in both direction, and ladder main is made as two flap-type structures, then can not only meet the instructions for use of most of rig, be beneficial to patch blanking, making, and gap bridge ladder specification can be reduced, improve its interchangeability, two flap-type structures also save transport space simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of adjustable gap bridge ladder, and the rig supporting gap bridge ladder specification solving prior art existence is many, the problem of installation and maintenance inconvenience.
The technical scheme that the utility model adopts is, a kind of adjustable gap bridge ladder, comprise the symmetrically arranged ladder main of two lobes, every lobe ladder main bottom surface is provided with a set of height adjustment mechanism, two lobe ladder main upper end joints are provided with hasp, ladder main step both sides are provided with railing, and inside every lobe ladder main, corresponding shaft coupling installation site is respectively arranged with two slide rails and multiple years filament plates, is all provided with one group of guard shield that can slide in two slide rails of every side.
Adjustable gap bridge ladder of the present utility model, is further characterized in that:
The structure of height adjustment mechanism is, comprises the bolt be fixedly connected with ladder main, and the bolt other end was set with pipe, crosses pipe outer end by backing plate apical grafting basis; Cross pipe the inner to be connected with bolt by nut shim and locking nut.
In working order, guard shield by lock bolt with carry a filament plate and tighten and be connected.
The beneficial effects of the utility model are, structure is simple, arrange rationally, can meet the instructions for use of most of rig to gap bridge ladder, decrease transport space simultaneously, save cost of transportation.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, Fig. 3, the structure of the utility model device is, comprise the symmetrically arranged ladder main 2 of two lobes, every lobe ladder main 2 bottom surface is provided with height adjustment mechanism 1, for regulating the whole height of ladder, two lobe ladder main 2 upper end joints are provided with hasp 6, ladder main 2 step both sides are provided with railing 3, inside every lobe ladder main 2, corresponding shaft coupling installation site is respectively arranged with two slide rails 4 and multiple years filament plates 12, for installing and secure shroud 5, in two slide rails 4 of every side, one group of guard shield that can slide 5 is all installed;
With reference to Fig. 4, guard shield 5 has locating hole, and when guard shield 5 is adjusted to shaft coupling requirement width, be connected by lock bolt 13 by locating hole with the filament plate 12 that carries in ladder main 2, it is firm guard shield 5 and ladder main 2 can be locked;
With reference to Fig. 2, the structure of height adjustment mechanism 1 is, comprises the bolt 7 be fixedly connected with ladder main 2, and bolt 7 other end was set with pipe 10, crosses pipe 10 outer end by backing plate 11 apical grafting basis; Cross pipe 10 the inner to be reliably connected with bolt 7 by nut shim 9 and locking nut 8.
Operating principle of the present utility model is,
When adjustable gap bridge ladder needs to regulate height, as Fig. 2, unclamp locking nut 8, adjusting screw(rod) 7 exposes the length of nut shim 9, after making adjustable gap bridge ladder height meet work instructions for use, tightens locking nut 8;
When adjustable gap bridge ladder needs adjustment width, as Fig. 3, Fig. 4, unclamp the lock bolt 13 being fixed on and carrying on filament plate 12, guard shield 5 moves along slide rail 4, after length to the adjustable gap bridge ladder width regulating guard shield 5 to stretch out ladder main 2 meets job requirement, lock bolt 13 and a year filament plate 12 are tightened, to reach the object compressing guard shield 5.
When adjustable gap bridge ladder transport, as Fig. 5, the hasp 6 between ladder main 2 is unclamped, ladder main 2 can be split into two lobe transports.
