Abstract
The invention discloses a platform lifting mechanism which is simple in structure and low in cost and can satisfy lifting working requirements of a small platform. The platform lifting mechanism comprises pulleys, lifting wire ropes, chain blocks, fixators, fixing seats and supporting lugs. The pulleys are fixed at the top ends of spud legs on the platform. One end of each chain block is connected with one supporting lug on each fixing seat, the other end is connected with one end of each lifting wire rope, and each lifting wire rope is connected with the other supporting lug on each fixing seat after being wound around each pulley. The supporting lugs are symmetrically fixed on the two sides of each fixing seat, and the centers of the connecting holes in the supporting lugs on the two sides directly face the centers of the two sides of each lifting wire rope which is wound around each pulley and downward vertically. The fixing seats are fixed on the platform. One end of each fixator is fixed on each fixing seat, the fixators and the fixing seats are hollow parts, the spud legs are sleeved with the fixators and the fixing seats, and the fixators and the fixing seats can slide with the platform along the spud legs.
Description
Technical field
The present invention relates to a kind of platform lift system.
Background technology
Large-scale lifting table adopts hydraulic cylinder jacking mechanism and rack-and-gear lifting mechanism usually, but for small-sized platform, because this body structure of platform is relatively simple, lightweight, lift is little, cost is low, if application cylinder jacking mechanism or rack-and-gear lifting mechanism, then seem that jacking system is too numerous and jumbled, high cost.
Summary of the invention
What object of the present invention was platform provides a kind of novel, easy, with low cost lifting mechanism from lifting, meets the lift work requirement of Miniature lifting platform.
The present invention is realized by following proposal, and platform lift system comprises pulley, promotes cable wire, chain block, permanent seat, journal stirrup, fixer; Pulley is installed on the spud leg top of platform; Chain block one end is connected with journal stirrup, and the other end is connected with the one end promoting cable wire; After lifting cable wire walks around pulley, be connected with another journal stirrup on permanent seat; Journal stirrup symmetry is arranged on permanent seat both sides; Permanent seat and platform are fixed; Fixer one end and permanent seat are threaded connection, fixer and permanent seat are hollow member, be enclosed within spud leg, can slide along spud leg together with platform, four phase places of spud leg are all equidistantly furnished with locking hole, when platform rises to the height of needs, by latch by fixer and pile leg locking, thus locking platform.
Principle of work: platform lift system as above, chain block one end is connected with journal stirrup, and one end is connected with cable wire, is connected after cable wire walks around pulley with the journal stirrup of permanent seat opposite side.During lifting platform, operating personnel pulls the chain (or cable wire) of cucurbit, and the chain (or cable wire) of band suspension hook is shortened, and promotes cable wire around pulley motion, and the length of adjustment two ends lift system is isometric automatically, thus band moving platform promotes.
The present invention has the following advantages:
1. promote cable wire vertically to arrange, without all the other direction component, therefore cucurbit pulling force is all for lifting platform;
2. fixer and permanent seat are threaded connection, when after the setting height that platform rises to relative to spud leg, when spud leg hole and retainer hole deflection, can by the position of screw thread pair adjustable fixer, retainer hole and spud leg hole are aligned, thus platform locking latch is locked smoothly;
3. mechanism's composition is simple, with low cost; Install, dismounting flexibly, need not accessory equipment; Easy to use, need not extra power source.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
As shown in Figure 1, described platform lift system comprises pulley 1, promotes cable wire 2, chain block 3, fixer 4, permanent seat 5, journal stirrup 6; Pulley 1 is fixed on spud leg 7 top of platform 8; Chain block 3 one end is connected with the journal stirrup 6 on permanent seat 5, and the other end is connected with the one end promoting cable wire 2; After lifting cable wire 2 walks around pulley 1, be connected with another journal stirrup on permanent seat 5; Journal stirrup 6 symmetry is arranged on permanent seat 5 both sides, and the connecting bore center of both sides journal stirrup 6 faces respectively and walks around pulley 1 center, lifting cable wire 2 both sides straight down; Permanent seat 5 is fixed with platform 8; Fixer 4 one end and permanent seat 5 are fixed, fixer 4 and permanent seat 5 are hollow part, be enclosed within spud leg 7, slide along spud leg 7 with platform 8, four phase places of spud leg 7 are all equidistantly furnished with locking hole, when platform 8 rises to the height of needs, by latch, fixer 4 and spud leg 7 are locked, thus locking platform 8.
When platform 8 promotes, operating personnel pulls chain block 3, and the carrying chain of chain block 3 is shortened, and promotes cable wire 2 and walks around pulley 1 to chain block 3 one side roll, chain block 3 carries chain and promotes the bont overall length shortening of cable wire 2 composition, and platform 8 is promoted.
Fixer 4 and platform locking latch and permanent seat are locked after promoting and putting in place by platform 8.
As shown in Figure 2, described platform lift system pulley 1, it act as guiding and reinforcement.
As shown in Figure 3, described journal stirrup 6 symmetry is arranged on permanent seat 5 both sides; Permanent seat 5 is fixed with platform 8; Its effect connects lift system and platform 8, keeps promoting cable wire all the time straight down, thus the pulling force making hand lift system all the time vertically, is all converted into platform 8 hoisting force.
Fixer 4 as shown in Figure 4, one end and permanent seat 5 are threaded connection, and are enclosed within together with permanent seat 5 on spud leg 7, and its effect is guide piece when promoting as platform 8 and locking platform 8 and spud leg.
