At present, the three full free gantries of joint are mainly by the two-stage stretching oil cylinder, and two cover pulley block mechanisms are realized hoisting of goods and descend, the pulley of first set assembly pulley is arranged on front oil cylinder, chain one end is connected with goods shelf, and after walking around sprocket wheel, the other end is connected on the inner upright mounting crossbeam; The pulley of the second cover assembly pulley is arranged on portable beam, and an end of chain is connected with the chain stays on inner upright mounting, and after walking around sprocket wheel, the other end is connected with the chain stays of outer mast.As shown in Figure 1 and Figure 2, the second cover assembly pulley mainly comprises: outer mast 1, middle door frame 2, inner upright mounting 3, portable beam 4, oil cylinder 5 and high-pressure rubber pipe etc.The connection of this mechanism is: oil cylinder 5 lower ends are fixed on outer mast 1 base plate 11, oil cylinder upper end piston rod is fixed on portable beam cylinder head seat 41, there are two sprocket shafts 42 at the portable beam two ends, two sprocket wheels 7 are contained on sprocket shaft, chain 6 is walked around sprocket wheel 7, it is fixing that one end is fixed on chain stays 12, one ends and the inner upright mounting chain stays 31 of outer mast, and portable beam 4 passes through 4 bolts and is connected door frame 2 connections.The motion of a whole set of assembly pulley is as follows: hydraulic oil enters oil cylinder bottom oil cylinder, the first set assembly pulley is completed freely and is hoisted, when hydraulic oil continues to enter oil cylinder, second overlaps mechanism starts working, cylinder head seat 41 on oil cylinder 5 jack-up portable beams, middle door frame and portable beam are integrally formed, and the chain-driving inner upright mounting on portable beam and then rises, inner upright mounting drives goods shelf to be continued to hoist again, completes whole uphill process.This kind structure has the following disadvantages: 1, portable beam is comprised of cylinder head seat 41, sprocket shaft 42, plate 43, processing welding more respectively, and cost is high, and efficient is low; 2, need to weld two bearings on middle door frame, auger shell pit on bearing, requiring of four tapped bore pitch-rows is high; 3, middle door frame is connected with bolt with movable beam slab, and is unreliable, assembles loaded down with trivial details.4, test run and when maintenance, if the pulley on portable beam, sprocket wheel have problem, need to take off portable beam is whole, the time is long, and work capacity is large.
Summary of the invention
Present three joint forklift door frame manufacturing cost high efficiencies are low, assembling is loaded down with trivial details in order to solve, the problems referred to above of test run and maintenance difficult etc., the utility model proposes second of a kind of designs simplification, assembling is easy to maintenance and low cost of manufacture production efficiency is high fork truck three full free gantries of joint and overlap the pulley block system device.
the second cover pulley block system device of the fork truck three full free gantries of joint of the present utility model, comprise outer mast, middle door frame, inner upright mounting and the chain system that promotes and can drive the inner upright mounting motion by middle door frame, described chain system comprises sprocket wheel and chain, described outer mast bottom is provided with for the fixing base plate of hoist cylinder, the outer mast both sides are provided with for the fixing outer mast chain stays of chain one end, inner upright mounting is provided with for the fixing inner upright mounting chain stays of the chain other end, the both sides of described middle door frame are provided with the oil cylinder seat that connects the hoist cylinder piston rod, be provided with the sprocket shaft that sprocket wheel is installed on the middle door frame above described oil cylinder seat.
The second cover pulley block system device of the fork truck three full free gantries of joint of the present utility model has been cancelled the portable beam assembly, with the sprocket shaft on portable beam with oil cylinder seat is direct and the welding of middle door frame, simplified the integral structure of the three full free gantries of joint, make the processing and manufacturing cost low, connect reliable, assembling is simple, and test run is easy to maintenance.
