Abstract

The utility model relates to a vehicle ladder system which comprises a ladder mounted on a front coaming of a vehicle through a bracket, wherein the ladder comprises two parallel ladder beams and a pedal hinged with the two ladder beams; the bracket comprises a support rod and connecting pieces connected at the two ends of the support rod; the shafts of the connecting pieces at the two ends of the support rod are rotatably connected in the shaft holes at the end parts of the two ladder beams; a pin hole is formed in the two ends of the support rod respectively; a pin rod is inserted into each pin hole; and the end part of the pin rod is matched with a limiting hole of a connection lug of each ladder beam. The pin rod serves as the support rod of the ladder when the ladder is pushed up and as a limiting device when the ladder is retracted, and the ladder clings to the lower surface of the front coaming for sure, thus the ladder system can be quickly expanded and fixed when in use; the ladder system can be quickly locked and fixed when retracted and is attached to the vehicle and occupies little space; and meanwhile, the ladder system has a simple structure and is convenient and reliable to operate.

Description

A kind of vehicle ladder system

Technical field

The utility model relates to a kind of cat ladder instrument, relates in particular to the vehicle ladder system.

Background technology

In daily production and life, ladder is widely used in every field, also can be different in its structure of different workplaces, but major part is all independently or fixed structure.Therefore for bulky heavy vehicle, roof need to load certain goods and materials, needs a kind of cat ladder to satisfy equipment operator or maintenance personal to the demand of roof climbing, simultaneously, also needs to satisfy the requirement that as far as possible takes up room less when not using.

Summary of the invention

The purpose of this utility model is exactly for defects, and a kind of ladder system of the vehicle of packing up fast or launching is provided.

the technical scheme that its technical problem that solves the utility model adopts is: a kind of vehicle ladder system is provided, comprise by support and be arranged on the cat ladder on coaming plate before vehicle, described cat ladder comprises that two parallel cat ladder beams reach and two pedals that the cat ladder beam is hinged, described support comprises support bar and is connected to the connector at support bar two ends, the axle of support bar two end connections is rotatably connected in the axis hole of two cat ladder beam end, the two ends of described support bar respectively have a pin hole, pin rod is inserted in pin hole, and match with the spacing hole of the engaging lug of cat ladder beam in the end of pin rod.

Described connector comprises side plate and junction plate, and described junction plate is fixed on before vehicle on coaming plate by securing member, and described axle is fixed on described side plate.

Also have the through hole that connects support bar on described side plate, described through hole is communicated with pin hole.

The utility model compared with prior art, beneficial effect is: pin rod when cat ladder is propped up as the support bar of cat ladder, pin rod when cat ladder is packed up as stopping means, guarantee that cat ladder is close to front coaming plate soffit, therefore rapid deployment is also fixing in use for this ladder system, rapidly its locking is fixed when packing up, and is fitted with vehicle, take up room few, this ladder system is simple in structure, easy to operate, reliable simultaneously.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in accompanying drawing:

Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model;

Fig. 2 is the scheme of installation that the utility model is kept away;

Fig. 3 is that the utility model launches schematic diagram;

Fig. 4 is the local enlarged diagram of Fig. 3;

Fig. 5 is that the utility model is packed up schematic diagram;

The specific embodiment

as Fig. 1, shown in 2, a kind of vehicle ladder system, comprise cat ladder, support, cat ladder is arranged on before vehicle on coaming plate 9 by support, cat ladder comprises that two parallel cat ladder beams 1 reach and two pedals 2 that cat ladder beam 1 is hinged, the number of pedal 2 can be decided by the size of contour of the vehicle, two cat ladder beam 1 ends respectively have an axis hole 1.1, support comprises support bar 6 and is connected to the connector 4 at support bar 6 two ends, connector 4 comprises side plate 4.1 and junction plate 4.2, respectively have a through hole 7 on the side plate 4.1 of two connectors, support bar 6 is supported in the through hole 7 of two connectors, axle 5 on two connector side plates 4.1 is rotatably connected in the axis hole 1.1 of two cat ladder beam end, the junction plate 4.2 of two connectors is fixed on before vehicle on coaming plate 9 by securing member, thereby make support be fixed on the front coaming plate of vehicle.

As shown in Fig. 1,4,6, respectively have spacing hole 3.1 on the engaging lug 3 of two cat ladder beams 1, the two ends of support bar 6 respectively have a pin hole 6.1, pin hole 6.1 is communicated with through hole 7, pin rod 8 is inserted in pin hole 6.1, and the end of pin rod 8 is passed through hole 7 and matched with the spacing hole 3.1 of the engaging lug of cat ladder beam.

When using cat ladder, as shown in Fig. 3,4, pin rod 8 inwardly slides, make pin rod 8 break away from spacing hole 3.1, then cat ladder is risen, then pin rod 8 is outwards slided, the part of pin rod 8 reaches outside through hole 7, and cat ladder beam 1 is resisted against on the pin rod of through hole outside, and this moment, pin rod played the effect of supporting cat ladder.

Do not use cat ladder constantly, as shown in Fig. 5,6, pin rod 8 will inwardly slide, pin rod 8 is slided in through hole 7, then cat ladder is packed up, then pin rod 8 is outwards slided, pin rod 8 passes in the spacing hole 3.1 that through hole 7 is inserted into engaging lug, and at this moment, pin rod plays spacing and effect locking.

Pin rod 8 of the present utility model plays two effects: when cat ladder is propped up as the support bar of cat ladder; When packing up, cat ladder as stopping means, guarantees that cat ladder is close to front coaming plate soffit.

Ladder system of the present utility model, rapid deployment and fixing, fix its locking rapidly when packing up in use, and fit with vehicle, takes up room few, and this ladder system is simple in structure, easy to operate, reliable simultaneously.

The above is described embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection domain of the present utility model.
