Abstract
The utility model relates to a special mechanism for an engineering plant to get on/off a transport vehicle. The rear end of a vehicle frame of the transport vehicle is provided with two two-way hydrocylinders which can rotate certain angles around a mounting axes; the lifting of the hydrocylinders is controlled by a multiple unit valve; when the hydrocylinders face downwards, the hydrocylinders are taken as two legs of the transport vehicle to prevent the front part of the engineering plant from tilting when the engineering plant gets on/off the transport vehicles; and when the two hydrocylinders are connected with a ladder, the hydrocylinders provide power for lifting of the ladder and fixing the ladder when the ladder is lifted to a raising position. The utility model is a special mechanism for an engineering plant to get on/off a transport vehicle with the advantages of simple structure, low production cost, and safe, reliable and convenient use.
Description
Technical field
The utility model relates to a kind of transportation means, relates in particular to a kind of transportation means that is specifically designed to the loading and unloading construction machinery and equipment.
Background technology
Along with improving constantly of living standards of the people, the engineering of more and more enriching people has put into operation, and this just needs more construction machinery and equipment place in operation.Along with the continuous realization of mechanization of agriculture, also be on the increase as these field machines such as crawler type rice harvesters.The policy in the new rural area of nation-building deepens continuously, and back road is become better and better, and these construction machinery and equipments and crawler type field machine just can not be in these travels down.This just needs special these mechanical special-use vehicles of transportation.The utility model is exactly the special mechanism that applies on these special-use vehicles.
The cat ladder of getting on or off the bus that traditional special-use vehicle adopts is manual, putting down and erect cat ladder all is by manually lifting, if cat ladder is too heavy, manual handling is got up just very difficult, and cat ladder is unsettled under the state of erecting, in order to prevent that cat ladder from falling down automatically, a big spring all has been installed in the cat ladder bottom.Spring can prevent that cat ladder from falling down automatically, when still putting down, also must overcome its elastic force, and manipulation will more have been required great effort like this.
Construction machinery and equipment is in transport vehicle up and down, because center of gravity all at vehicle rear, is easy to cause the perk of vehicle head, thereby easily causes safety misadventure.For fear of the generation of analogue, traditional special-use vehicle all solves in the method for two supports of vehicle rear welding or the low dull and stereotyped special trailer of employing.Cost with low dull and stereotyped special trailer is too high; Not attractive in appearance again in two supports of vehicle rear welding, handle trouble.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, thereby develops construction machinery and equipment a kind of simple in structure, the safe and reliable special mechanism of transport vehicle up and down.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of construction machinery and equipment is the special mechanism of transport vehicle up and down, include cat ladder, it is characterized in that: described cat ladder is two cat ladders, and both sides arrange that an end and the vehicle frame rear end of cat ladder are hinged; Vehicle frame rear end below cat ladder be equipped with a pair of can be around the double-act-ing hydraulic J-Horner that axis rotates to an angle be installed, described hydraulic ram links to each other with multiway valve.
The technical solution of the utility model also can be further perfect,
As preferably, the lower end of described hydraulic ram is provided with leg, is connected for detouchable between described leg and the hydraulic ram cylinder rod.The general bearing pin that adopts connects, and connects when needed, and the time spent is not unloaded.
As preferably, be provided with an oil cylinder mounting hole in the bottom surface of cat ladder.Be used to make between oil cylinder piston bar and the cat ladder location and be connected.
As preferably, described multiway valve is installed between two oil cylinders.
Therefore, the utility model is at hydraulic ram vertically downward the time, being used as two supporting legs of transport vehicle uses, prevent up and down anterior perk during transport trolley of construction machinery and equipment, when these two hydraulic rams link to each other with cat ladder, be used as cat ladder lifting power usefulness, and when cat ladder is lifted raised position, play fixedly cat ladder usefulness.The beneficial effects of the utility model are simple in structure, and productive costs is low, the safe and reliable and construction machinery and equipment special mechanism of transport vehicle up and down very easily.
Description of drawings
Accompanying drawing 1 is a kind of structure side view of the present utility model;
Accompanying drawing 2 is a kind of structure upward views of the present utility model.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
From Fig. 1 and Fig. 2 as can be seen, the utility model comprises two cat ladders 3, both sides are arranged, one end and vehicle frame 8 rear ends of cat ladder are hinged, hinge-point 6, the cat ladder hydraulic ram mounting hole 7 of having gone to the bottom, vehicle frame 8 rear ends below cat ladder be equipped with a pair of can be around the double-act-ing hydraulic J-Horner 1 that axis 2 rotates to an angle be installed, hydraulic ram links to each other with multiway valve 4.When hydraulic ram is in vertical position, handle the operating handle of multiway valve 4, can stretch out oil cylinder downwards, the cylinder rod of oil cylinder lower end links to each other with leg 5 by bearing pin.After leg stably touches ground, unclamp the operating handle of multiway valve 4, at this moment hydraulic ram 1 just is used as two supporting legs usefulness.Like this, construction machinery and equipment is transport vehicle up and down, and transport vehicle then can stably be parked on the ground.When construction machinery and equipment up and down behind the transport vehicle, throw off bearing pin, separate at once between cylinder rod and the leg, the operating handle of reversible control multiway valve 4 is regained hydraulic ram 1.Hydraulic ram 1 just can be installed axis 2 around it and rotate.Rotate hydraulic ram 1, to the hydraulic ram mounting hole 7 of cat ladder 3, handle extension elongation that the operating handle of multiway valve 4 comes regulator solution compressing cylinder 1 to mounting hole length unanimity, put on supporting pin, at this moment, hydraulic ram is just as the lifting power of cat ladder.Handle the operating handle of multiway valve 4, make hydraulic ram 1 elongation, cat ladder just slowly rises, and when cat ladder is raised to maximum position, loosens the operating handle of multiway valve 4, and at this moment hydraulic ram 1 just is fixed on this position to cat ladder 3 reliably.The operating handle of reversible control multiway valve 4 just can slowly fall cat ladder 3, just construction machinery and equipment up and down.
