An angle can be freely regulated totally on orbit surfaces of different tilting angles to cause the elevating ladder to be perpendicular to the ground in a maximum accurate mode and be fixed, errors of perpendicularity are maintained within 0.75 deg, and thus an operating staff can securely go up and down.
Description
Technical field
The utility model relates to a kind of in order to satisfy portable lifting cat ladder smoothly work and custom-designed angular adjustment corollary apparatus under various inclination working conditions.
Background technology
In field of track traffic, portable lifting cat ladder can make things convenient for service personnel trackwork face up and down freely.When the needs service work, operating personal is climbed up stop tool car in orbit by the lifting cat ladder, lifting cat ladder in the past only is to be connected with tool car on the track by the hinge joint wheel word, when tool car is in the bevelled orbital plane, rely on gravity of self and hinge joint wheel word can make its natural vertical ground with tool car bonded assembly cat ladder, but the angular error of this natural plumbness is bigger, can not accomplish high-precision positioning states, simultaneously because can not firm fixation, therefore cat ladder rocks before and after being easy to generate in the time of about the operating personal, even the formation operating personal dangerous tendency of leaning back up and down the time, cause safety hazard.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of lifting cat ladder angle regulator, exist than mistake and can not firm fixation be easy to generate the defective of rocking with the angle that overcomes the prior art vertical ground.
The technical solution of the utility model is as follows,
A kind of lifting cat ladder angle regulator, comprise and lifting cat ladder and tool car bonded assembly slewing arrangement, it is characterized in that also comprising an anchor fitting, two connecting panels that described anchor fitting comprises strut bar and is positioned at the strut bar head and the tail and flexibly connects with strut bar, wherein a connecting panel is fixed on the cat ladder, and another piece connecting panel is fixed on the tool car.
As to improvement of the present utility model, described being fixedly coupled with tool car is set side by side with a screw that row is parallel and spacing does not wait on the plate, and strut bar and this connecting panel adopt bolted mode, corresponding to the different angle of lifting cat ladder rotation, the tie bolt between strut bar and the connecting panel is corresponding to the screw on the diverse location.
As to improvement of the present utility model, the connecting panel of the strut bar other end is welded on the cat ladder, and strut bar flexibly connects by bolt and this connecting panel.
As to improvement of the present utility model, described slewing arrangement comprises rotating shaft, rotating shaft base, rotary bottom plate and rotating shaft connecting panel, the described plate that is rotationally connected is connected with the lifting cat ladder by welding, described rotating shaft is connected with the lifting cat ladder by the axis hole on the rotating shaft connecting panel, described rotating shaft is installed on the rotating shaft base by bolt and axle head baffle plate, and described rotating shaft base is captiveed joint with tool car with rotary bottom plate by tie bolt.
Also be provided with a filler port and a circle oil resevoir in above-mentioned rotating shaft and connecting panel bonded assembly part, it rotated flexibly thereby be used to add lubricating oil.
The beneficial effects of the utility model are, the design of anchor fitting, make on the orbital plane of differing tilt angles, angle regulator easily adjusting angle so that the relative ground of lifting cat ladder accomplish the vertical of maximal accuracy and fixed, the error of perpendicularity maintains in 0.75 degree, can also suit measures to local conditions simultaneously according to the environmental conditions needs, keep the cat ladder tendency that slightly leans forward fixing, thus the staff can be safely about.
Description of drawings
Fig. 1 is a general construction scheme drawing of the present utility model;
Fig. 2 is the structural representation of anchor fitting of the present utility model;
Fig. 3 is the structural representation of slewing arrangement of the present utility model;
Scheme drawing when Fig. 4 is in the angle of inclination for tool car.
Scheme drawing when Fig. 5 is in another angle of inclination for tool car.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, the utility model comprises slewing arrangement 1 and anchor fitting 2,3 and 4 are respectively cat ladder and tool car, slewing arrangement 1 is that cat ladder 3 tilts to keep and the vertical substantially primary member in ground with orbital plane, on this basis, anchor fitting then can narrow down to the error of this vertical angle in the certain limit.
As Fig. 2, anchor fitting comprise strut bar 5, with cat ladder bonded assembly connecting panel 6 and with tool car bonded assembly connecting panel 7, connecting panel 6 is welded on the cat ladder, and with the strut bar bolted connection, another connecting panel 7 is fixed on the tool car, be set side by side with on it one row screw 8, strut bar 5 all adopts bolt 9 to be connected with connecting panel 6,7, but strut bar 5 leaves the gap with connecting panel 6 binding sites, is convenient to strut bar and rotates around tie bolt 9 screw rods, and the A that sees below among Fig. 2 is to view.As Fig. 1, generally speaking, orbital plane is parallel with ground, thereby lifting cat ladder and tool car keep plumbness to fix naturally, but when tool car changes run-off the straight with working condition, as Fig. 4, unclamp the strut bar on the anchor fitting and the tie bolt of tool car, in the connecting panel of tool car, seek suitable screw according to the angle of inclination then and fix again; In like manner, as Fig. 5, when the reversing sense angle of inclination, the screw of the other end cooperates on strut bar and the connecting panel.
As Fig. 3, slewing arrangement comprises rotating shaft 10, rotating shaft base 11, rotating shaft connecting panel 12 and rotary bottom plate 13, this figure is the rotary device structure scheme drawing of being looked from the B direction among Fig. 1, rotating shaft connecting panel 12 is welded on the cat ladder 3, in the axis hole that rotating shaft 10 is inserted on the connecting panel 12, rotating shaft 10 is vertically fixed on the rotating shaft base 11 by bolt and axle head baffle plate, rotating shaft base 11 is fixed together by tie bolt 14 and rotary bottom plate 13 and tool car 4, and the part that is connected at rotating shaft 10 and connecting panel 12 is provided with a filler port and oil resevoir 15.When tool car changes run-off the straight with the track condition, after having unclamped the tie bolt of strut bar on the anchor fitting and tool car, the gravity of cat ladder dependence itself is by the rotating shaft connecting panel 12 on the cat ladder, produced rotation round the rotating shaft 10 that is fixed on tool car, made cat ladder and ground remain plumbness.Because the bolt of rotating shaft connecting panel, rotating shaft, rotating shaft base, rotary bottom plate and associated and the strength and stiffness of axle head baffle plate have fixing account form, so satisfy the safe handling requirement fully, and filler port be set and oil resevoir makes lubricated the rotation conveniently between rotating shaft and the rotating shaft connecting panel.
