Abstract

A loading and unloading vehicle is composed of an automobile chassis, a capstan engine, two parallel guide rails and a hydraulic cylinder. The automobile chassis comprises a supporting bracket and hoist cylinders at the fore-and-aft points of both sides of the supporting bracket. Two parallel guide rails and the capstan engine are respectively fixed to a frame, wherein, the cables of the capstan engine are in the longitudinal middle point of the frame, and hydraulic cylinders are respectively installed on the front and the rear of both sides of the frame; the lower end of each hydraulic cylinder is connected with the side of the supporting bracket, whereas the upper end is connected to the corresponding side of the frame. As long as the hydraulic cylinder is adjusted, the loading and unloading vehicle directly makes the rear ends of the guide rails adjacent to the earth surface, and makes a vehicle box body with cargoes directly climb to the setting location along the guide rails; simultaneously the guide rails rapidly rise to the position which is parallel with the guide rails of the trucks, and then the cargoes are sent to the trucks. The utility model dispenses with a guide plate assembly, and can finish loading and unloading operation by drawing the vehicle box body to slide on the guide rails.

Description

Loading-unloading vehicle

Technical field

The utility model relates to a kind of handling tool, especially refers to the loading-unloading vehicle of a kind of energy lifting.

Background technology

Usually adopt manpower or ladder or flat truck to finish to the cargo handing on passenger vehicle, high capacity waggon or the train, then mainly rely on fork truck or crane to carry out to the cargo handing on big article such as the freight container, though these instruments can reach the purpose of handling goods, but because it works together and both required great effort, make work efficiency extremely low again, thereby more and more be not suitable for the requirement of modernized operation.For this reason, the automobile that people design some loading-unloading vehicles or energy automatic loading and unloading comes, be " a kind of automobile of self-loading and unloading vehicle case " of CN2374394Y a kind of self-loading and unloading vehicle that comes to this wherein as publication number, it comprises car chassis, winch, slide rail, elevating ram, box body and foldable type guide plate assembly, this guide plate assembly is again by leading plate, form with supporting leg and pull bar that leading plate is hinged, during use, foldable type guide plate assembly is installed in the rear portion of slide rail, make leading plate concordant with slide rail, when loading, under the traction by the winch steel rope, box body is climbed along leading plate and slide rail move to desired location, at this moment, winch stops operating, elevating ram withdrawal and drive slide rail and box body reset together and balance, and operation promptly effects shipment.And when unloading, operation order is with above-mentioned opposite, and box body is under the effect of conducting oneself with dignity, along slide rail, guide plate downslide.Obviously, this self-loading and unloading vehicle has solved above-mentioned defective well.But in use find, because the ground at actual loading scene is usually also out-of-level, therefore when an end of guide plate is put in rugged ground, can't make guide plate concordant fully mutually with slide rail, so when handling goods, box body is moved up and down have some setbacks, even can't move up and down; Secondly, it is applicable to loads onto automobile with goods or the goods on self car is unloaded in ground from ground, therefore still can't the goods on other vehicle be loaded and unloaded; Take second place, when operating, all need artificial installation or removal guide plate assembly at every turn, use comparatively trouble; Moreover, above-mentioned winch and elevating ram all are installed on each automobile, make on the one hand complex structure also to make therefore still to be subjected to certain restriction in the use by the manufacturing cost height on the other hand.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of loading and unloading nimbly and freely, conveniently at above-mentioned prior art present situation, and the loading-unloading vehicle of high efficiency.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this loading-unloading vehicle comprises car chassis, winch, two closed slides and hydraulic actuating cylinder, be fixed with drag hook on the described winch cable wire, it is characterized in that: described car chassis comprises bearing support again and is positioned at the hoist cylinder of locating before and after the bearing support both sides, described two guide rails and winch are separately fixed on the framework, wherein the cable wire of winch is positioned at the longitudinal middle part place of framework, this framework then is positioned on the bearing support, and be respectively arranged with above-mentioned hydraulic actuating cylinder in the front and back of its both sides, the lower end of each hydraulic actuating cylinder is connected on the side of bearing support, and the upper end is connected with corresponding frame facet.

Can also be fixed with an auxiliary winch on the described framework, back-end framework is provided with two fixed pulleys spaced apart, and an end of two steel wires is provided with hook respectively, and the other end is respectively by linking with auxiliary winch behind the corresponding fixed pulley.

On described each guide rail, can be provided with knock hole, its lock body location of matching with the box body bottom that is positioned at goods.

Compared with prior art, advantage of the present utility model is: because hydraulic actuating cylinder is positioned at place before and after the framework both sides, so the regulator solution cylinder pressure, can make guide rail directly be adjacent to ground, align with ground guide, the box body that goods is housed is directly risen to desired location along guide rail; And simultaneously by the adjusting to each hydraulic actuating cylinder, make guide rail rise apace with lorry on guide rail mutually concordant, goods is delivered on the lorry, therefore, the utility model need not the guide plate assembly, as long as the pulling box body slides on guide rail, just can finish loading and unloading operation, and whole process makes its work efficiency higher conveniently, freely, fast; In addition, also can be by auxiliary winch, the lifting ground guide, the degree of dip of framework when reducing operation is so that spur box body more like a cork.
