Abstract
The utility model relates to a loading and unloading device used for a vehicle and a container vehicle, particularly a hydraulic lifting automatic joining loading and unloading plate bridge, and is composed of a circuit oil pump, a multi-way reversing valve, an overflow valve, a lifting oil cylinder, a telescopic oil cylinder, a telescopic plate bridge, a main plate bridge, a pre-buried ground hinge, and a pre-buried ground foot. The lifting and telescopic function of the main plate bridge is realized by means of the lifting oil cylinder, the telescopic oil cylinder in the main plate bridge, and the telescopic plate bridge. The utility model can be suitable for through height of different models of vehicles. The utility model is especially suitable for the loading and unloading of goods of large container vehicles.
Description
The utility model relates to the handling equipment that a kind of automobile, container car are used, and particularly a kind of hydraulic lifting overlaps the loading and unloading slab bridge automatically.
Present automobile and container car are when handling goods, need take with the timber plate and be placed on the tailstock groove, its gradient also will be adjusted with other material, and the slab bridge of overlap joint is also very dangerous in use like this, overweight or domatic too steep as goods, its slab bridge all is prone to fault, is not the fracture of slab bridge pontic, is exactly that the slab bridge slip causes the goods damage.
The purpose of this utility model is to provide a kind of automatic compensation height that overcomes above-mentioned defective and length and overlaps the loading and unloading slab bridge automatically with hydraulic lifting that ground fixes.
The technical solution of the utility model realizes as follows: hydraulic lifting overlaps the loading and unloading slab bridge automatically by circuit oil pump, multiple directional control valve, by pass valve, elevating ram, telescopic oil cylinder, flexible slab bridge, mainboard bridge, pre-buried cut with scissors and pre-buried lower margin is formed.Its circuit oil pump is connected and forms control housing with multiple directional control valve respectively through lead with by pass valve, control housing and pre-buried lower margin are fixed on the pre-buried ground in the lump; On the interface of the interior multiple directional control valve of I/O end difference Access Control cabinet of elevating ram and telescopic oil cylinder; The lower end of elevating ram is fixed on the pre-buried lower margin, and the lifting arm upper end in the elevating ram is fixed on mainboard bridge front end bottom; Telescopic oil cylinder is installed in the cavity of mainboard bridge, the front end of its expansion link be slidingly mounted on flexible slab bridge afterbody anterior in the mainboard bridge cavity and be connected, the cavity that the mainboard bridge is stretched out in the front portion of flexible slab bridge is taken and is placed on the support edge, pre-buried ground; The other end of mainboard bridge and pre-buried the hinge to hinged; It cuts with scissors on the support edge, pre-buried ground that is fixed on the other end pre-buriedly.
Adopt the utility model, its strong point immobilizes, and guarantees the safety and firmness of handling goods, and the variation of lifting arm and expansion link is applicable to the cargo handing of various different automobile types, and its mainboard bridge gradient is adjustable, guarantees goods at slab bridge up and down steadily freely.The utility model not only improves cargo handing speed, loading and unloading quality, has also reduced labour intensity.
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing:
Accompanying drawing 1, hydraulic lifting overlap loading and unloading slab bridge side schematic view automatically.
1 circuit oil pump among the figure, 2 multiple directional control valves, 3 by pass valves, 4 elevating rams, 5 telescopic oil cylinders, 6 flexible slab bridges, 7 mainboard bridges, 8 cut with scissors pre-buriedly, 9 pre-buried lower margins, 10 control housings, 11 lifting arms, 12 expansion links.
As shown: leaving a built-in groove apart from ground surface 900mm earlier, pre-buried lower margin (9) is fixedly mounted on the built-in groove bottom predeterminedly; Circuit oil pump (1), multiple directional control valve (2) and by pass valve (3) are separately fixed in the control housing (10), and also are fixed on control housing (10) in the built-in groove; In control housing (10), circuit oil pump (1) and multiple directional control valve (2) and by pass valve (3) are connected respectively with lead then, and multiple directional control valve (2) two group oil cylinder interface circuits are pulled out control housing (10); Again elevating ram (4) lower end is fixed on the pre-buried lower margin (9), and the group oil cylinder circuit in the multiple directional control valve (2) is connected to the input/output end port of elevating ram (4); On support edge, pre-buried ground of ground surface, fix two and cut with scissors (8) pre-buriedly, then with an end of mainboard bridge (7) and pre-buried cut with scissors (8) and be hinged.Its mainboard bridge (7) is shaped on chute in the cavity body slab bridge chamber, mainboard bridge (7) front end is an open end, open mainboard bridge (7) loam cake, the slab bridge (6) that will stretch is installed in the chute of mainboard bridge (7) front end, and the front end of flexible slab bridge (6) is positioned at outside the open end end of mainboard bridge (7).Telescopic oil cylinder (5) is fixed on middle part in mainboard bridge (7) chamber, the front end of expansion link (12) is connected with the afterbody of flexible slab bridge (6), and another group interface circuit of the multiple directional control valve (2) that the preformed hole that the input/output end port connection lead of telescopic oil cylinder (5) passes mainboard bridge (7) bottom and control housing (10) are interior is connected; At last the lifting arm (11) of elevating ram (4) is fixed on the bottom of mainboard bridge (7) front end.Be hydraulic lifting overlap automatically loading and unloading slab bridge install.
During use, after circuit oil pump (1) energized in the control housing (10), the lift height of its multiple directional control valve (2) beginning control main board bridge (7) and the collapsing length of flexible slab bridge (6).Mainboard bridge (7) is after the desired location stops, and its flexible slab bridge (6) also just is parked on the Len req, and automobile can directly be parked in the position that tailstock manger and expansion plate (6) are just overlapped, and can begin handling goods.
