Abstract
Provided is a low-panel cat ladder with a transverse moving function. A transverse sliding device is horizontally arranged on the end face of a back tail plate of a semitrailer. The transverse sliding device comprises a sliding rail, a sliding sleeve is arranged on the sliding rail, a cat ladder support is respectively and fixedly arranged on two sides of the sliding sleeve, the cat ladder supports are fixed on a sliding plate, the car ladder is arranged on the upper edge of the sliding plate in hinge mode, and the sliding plate is in upwards transmission connection with a piston rod of a hydraulic cylinder arranged on the back tail plate. Two sets of transverse sliding devices are horizontally and symmetrically arranged on the end face of the back tail plate of the semitrailer, and each set of transverse sliding device is provided with a cat ladder in corresponding matching mode. The lower end of an elastic connection rod at the bottom of the cat ladder is connected with the sliding sleeve. The low-panel cat ladder is simple in structure, practical in function, capable of being overturned upwards and downwards, capable of moving leftward and rightward to adjust the distance and suitable for requirements of different vehicles.
Description
Technical field
The utility model relates to a kind of low dull and stereotyped cat ladder with side travel function.
Background technology
Along with the continuous development of transit industry and building engineering in recent years, the form of engineering machinery vehicle and kind are also more and more, and the special low flat bed semi trailer of carrying engineering machinery vehicle (low flat truck is called for short in the back) has also obtained potential development.Low flat truck in use, its afterbody cat ladder is that engineering machine vehicle is used when getting on and off, but because the engineering machine vehicle type is more, and vehicle tyre (or crawler belt) spacing is either large or small, at this moment just the spacing of hanging down dull and stereotyped afterbody cat ladder is had relatively high expectations.Present low flat truck, its cat ladder horizontal cross all be a constant spacing, the excessive and situation that can not make the engineering machine vehicle of other model hang down flat truck smoothly up and down of cat ladder spacing often occurs.
Existing design only can realize that cat ladder vertically spins upside down, and does not have sway to adjust the function of spacing, and its function singleness can not be used the needs of multiple vehicle.
The utility model content
The utility model purpose is to provide a kind of low dull and stereotyped cat ladder with side travel function, can arbitrarily adjust its afterbody cat ladder spacing by user's request.
To achieve these goals, the utility model adopts following technical scheme: a kind of low dull and stereotyped cat ladder with side travel function is horizontally disposed with transverse slide on the tailgate end face behind the superimposed trailer; Described transverse slide comprises slide rail; Slide rail is provided with sliding sleeve, and the sliding sleeve both sides are fixed with the cat ladder bearing, and the cat ladder bearing is fixed on the sliding panel; The hinged sliding panel upper edge that is arranged on of cat ladder, sliding panel is in transmission connection with the piston rod that is arranged on the hydraulic actuating cylinder on the tailgate of back in the horizontal.
Behind the superimposed trailer on the tailgate end face horizontal symmetrical be provided with two the cover transverse slide, the corresponding supporting cat ladder that is provided with of every cover transverse slide.
The lower end of the spring pipe link of cat ladder bottom is connected with sliding sleeve.
The utility model is simple in structure, function is practical, and low dull and stereotyped cat ladder can spin upside down, and can sway adjust spacing, adapts to the not requirement of vehicle of the same race.
The utility model mode is a fluid control, simple and convenient and accurate positioning.After the sway function has been arranged, can carry polytype engineering machinery vehicle, realize the effect of " car is used " more, have good alerting ability and practicality, and novel structure, low dull and stereotyped vehicle performance do not influenced.

Fig. 2 is the structural representation of the utility model;
Fig. 3 is the right elevation of Fig. 2.
The specific embodiment
Embodiment: shown in Fig. 1-3, a kind of low dull and stereotyped cat ladder with side travel function is horizontally disposed with transverse slide on tailgate 4 end faces behind the superimposed trailer; Described transverse slide comprises slide rail 3; Slide rail 3 is provided with sliding sleeve 2, and sliding sleeve 2 both sides are fixed with cat ladder bearing 5, and cat ladder bearing 5 is fixed on the sliding panel 6; Cat ladder 1 hinged sliding panel 6 upper edges that are arranged on, sliding panel 6 is in transmission connection with the piston rod that is arranged on the hydraulic actuating cylinder 7 on the tailgate 4 of back in the horizontal.The lower end of the spring pipe link of cat ladder 1 bottom is connected with sliding sleeve 2.Behind the superimposed trailer on tailgate 4 end faces horizontal symmetrical be provided with two the cover transverse slide, the corresponding supporting cat ladder that is provided with of every cover transverse slide.
Because can not satisfying engineering machine vehicle, the cat ladder pitch problems hangs down dull and stereotyped situation to engineering machine vehicle up and down; The utility model rationally utilizes hydraulic efficiency pressure system and terms of mechanics knowledge; Release a kind of new-type cat ladder with transverse horizontal locomotive function; Its transverse horizontal moves power and is provided by hydraulic actuating cylinder, can effectively solve the problem that occurs owing to the cat ladder spacing.
Low dull and stereotyped new-type cat ladder adds an amount of butter, to guarantee that it is by enough slidings increasing the sliding sleeve 2 and slide rail 3 that can make cat ladder 1 side travel with tailgate bonded assembly position, rear portion between sliding sleeve 2 and the slide rail 3; Cat ladder bearing 5 is welded to connect with sliding panel 6, and sliding sleeve 2 and cat ladder bearing 5 are for being welded to connect; Increase an amount of butter between sliding panel 6 and the back tailgate 4, to guarantee to have desirable sliding effect therebetween; Hydraulic actuating cylinder 7 is fixed on tailgate 4 the place aheads, back, and horizontal positioned, and hydraulic actuating cylinder 7 heads are connected with sliding panel 6 through the groove of being opened on the tailgate 4 of back; So just can realize controlling the sway function of cat ladder 1, come the walking process of modulated pressure cylinder then through hydraulic valve through hydraulic actuating cylinder 7.
In addition, the utility model also can combine the hydraulic pressure cat ladder of low flat truck band hydraulic lifting performance, realizes the multifunction hydraulic cat ladder that hydraulic lifting and sway have simultaneously.
