Description

Portable freight container hydraulic hoist

The portable freight container hydraulic hoist of the utility model is that professional facility are loaded and unloaded in freight container traffic, relates to hoisting crane tool, fluid pressure actuator field.

Inland container loading and unloading at present are generally all on railway, highway, harbour and other places.Because freight container is very heavy, greatly about about 40 tons, large-scale steel cable lifting machinery or staggered form lifting machinery are all used in the various places loading and unloading, but should machinery huge, the cost height, and only necessarily among a small circle in work, can not load and unload with freight container traffic and carry, thereby after causing container trailer to arrive the somewhere, because of there not being special-purpose lifting machinery not unload immediately, can only open and to leave after goalkeeper's goods is unsnatched, promptly incur loss through delay the transportation turn-around time, be unfavorable for that again freight container recycles.Obviously, above-mentioned is exactly the shortcoming and the weak point of prior art.

The purpose of this utility model is to remedy the shortcoming and the deficiency of prior art, and providing a kind of can carry with trailer transportation, again the hydraulic portable hoist that can move arbitrarily on ground.

The utility model is realized by following technical scheme; Its whole mechanism is made up of a control setup and four oil cylinder actrs (being hydraulic hoist) as shown in Figure 1.Control setup comprises propulsion source 4, oil pump 3, oil filter 2, fuel tank 1, check valve 15, change-over valve 7, safety valve 6, compression indicator 8, flow valve 9 and three synchronous valve 10.They successively connecting relation be: propulsion source 4 and oil pump 3 connects, between oil pump 3 and oil filter 2, the fuel tank 1, between oil pump 3 and the check valve 15 and between check valve 15 and the change-over valve 7, all use oil pipe 5 UNICOMs between change-over valve 7 and three synchronous valve 10 and safety valve 6, the flow valve 9.The structure of oil cylinder actr as shown in Figure 1 and Figure 2; Its moving square main part hoist cylinder 16 usefulness forward flange boards are fixed on the bearing support 17, the inside top of bearing support 17 is installed four case angles that an angle handrail 21 is used to buttress freight container, its inside bottom is installed four holes that a fixer 19 is used to block freight container, removable link rod 13 is connected in the outside of bearing support 17, a control wheel 14 is installed on its top, one man operation when being used for the elevator installation, the piston rod of hoist cylinder 16 and base 20 are hinged, steamboat assembly 18 is fixed on the base 20 of stage clip supporting, bogie wheel assembly 12 is installed on the base 20, oil cylinder 16, reversible lock 24, check valve 15 usefulness oil pipes 5 UNICOMs reserve two oil inlet and outlet A separately ₁B ₁, A ₂B ₂, A ₃B ₃, A ₄B ₄, respectively have a cover pressure flexible pipe 22 and quick joint 23 connect with corresponding oil inlet and outlet separately in the connection place of control setup and four oil cylinder actrs 16.Propulsion source 4 has two kinds of patterns: a kind of is transportation type, and propulsion source is the driving engine of trailer itself, and control setup just is installed in the trailer bottom; Another kind is the ground moveable type, and propulsion source 4 is installed on the waggon for motor, control setup, arbitrarily moves for ground and uses.

Its principle of work is: propulsion source 4 drives oil pump 3 oil suction from fuel tank 1, unload by check valve 15 and change-over valve 7 (meta state) oil sump tank through oil filter 2, under the settling pressure of safety valve 6, their handle is all beaten to position, a left side change-over valve 7 and four change-over valves 11 adjustment, pressure oil is given four hoist cylinders 16 through flow valve 9 by synchronous valve 10 uniform distributions, elevator rose when pressure oil entered from the A mouth, otherwise with change-over valve 7 and 11 dozens of extremely right positions of change-over valve, when pressure oil enters from the B mouth, elevator descends, pressure oil pipe 22, quick joint 23 is used for connecting of control setup and hydraulic hoist, and reversible lock 24 guarantees that oil cylinder elevating safeties and optional position height stop.During use four elevators are pushed into place, four angles of freight container respectively and buttress four case angles and four fixers 19 are blocked four holes at the bottom of the case, connect with each elevator oil cylinder from control setup extraction pressure hose 22 with four angle handrails 21.Pressure oil enters A mouth oil cylinder piston bar promotion base 20 and overcomes steamboat stage clip kiss the earth, bearing support 17 is risen hold up freight containers, and pressure oil enters B mouth elevator and descends, and freight container is placed on the trailer, finishes handling procedure.

Advantage of the present utility model is: 1. originally long-pending little than similar elevator machinery body, occupy little space, but the one man operation; 2. in light weight, lifting power is big and adjustable, and convenient transportation is convenient to trailer transportation and is carried, and also can move arbitrarily on ground; 3. cheap, easy to maintenance and expense is low, can be widely used in station, harbour, on the various trailers of big and small freight department.Be that optimal machinery is loaded and unloaded in freight container traffic.
