The specific embodiment
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation; Explain technical scheme of the present invention below with reference to accompanying drawing.
As shown in Figure 1, the dynamic falling proof device of mechanical type of the present invention, comprises anti-fall bearing 1, anti-fall hook 2, spring 3, connecting rod 4, electromagnet 5, trolley conductor 6, trolley conduit 7, the first bearing pin 8, spring cotter 9, block 10, the second bearing pin 13; The second positive stop 11 is set on described anti-fall bearing 1; The 3rd positive stop 12; Wherein:
First hole that is located by connecting is offered at the anti-fall position that is hooked in its bending, with by the second bearing pin location and installation on anti-fall bearing; Simultaneously, the second be located by connecting hole and spring snapping circular hole offered respectively at anti-fall its two ends that are hooked in, make anti-fall hook adopt spring cotter to be located by connecting by this second one end that is located by connecting hole and connecting rod, the other end of connecting rod is located by connecting by the first bearing pin and electromagnet, and electromagnet is placed in guide base, therefore, anti-fall hook 2, connecting rod 4, electromagnet 5 form a slider-crank mechanism, wherein anti-fall hook and connecting rod 4 are as connecting rod mechanism, and electromagnet is as slide block mechanism; Spring fitting is in anti-fall bearing, and one end of spring and anti-fall bearing fix, the other end with anti-fall hook on set spring snapping circular hole be interlockingly connected.Therefore, anti-fall bearing plays the effect of fixing anti-fall hook, and can also limit the movement travel of anti-fall hook, it is to realize by the second positive stop set on anti-fall bearing, the 3rd positive stop, wherein, the combination of the first positive stop, the second positive stop, in running order for maintaining anti-fall hook, the 3rd positive stop is for maintaining anti-fall hook in off position.
Principle of work of the present invention is as follows:
By the present invention for multi-storied garage, its Main Function be prevent multi-storied garage in the process of operation because haulage cable or chain fracture suddenly make lifting table from falling from high altitude, guarantee the safety of vehicle and equipment in operational process.
1) power supply the principle
Lifting table, carrying out in dipping and heaving process, needs constantly to shift one's position up and down, and on each different position, lifting table can obtain electrical source of power again at any time, to obtain signal, realizes the break-make of electromagnet.Therefore patent of the present invention adopts trolley to power to electromagnet, and along the orbit parallel lay-up trolley conduit of lifting table, trolley conduit is semi-enclosed special-shaped tubular parts, is the base portion of safety sliding contact line.Trolley conductor is installed on lifting table, and the electromagnet that needs power supply is also fixed on (as shown in Figure 2) on lifting table, electromagnet and the synchronized operation of trolley conductor, the power taking from trolley conduit of trolley conductor, the delivery of electrical energy of trolley conductor is to control element.
2) mechanical anti-falling principle
Embodiment: lifting table installs respectively falling proof device on four angles, the symmetrical installation in front and back, symmetrical installation, four points are worked simultaneously.
Anti-fall bearing is fixed on lifting table, and electromagnetism iron rule is arranged on lifting table by guide holder, be that electromagnet can be arranged on lifting table to translation, wherein: anti-fall hook 2, connecting rod 4, electromagnet 5 form a slider-crank mechanism, wherein anti-fall hook and connecting rod 4 are as connecting rod mechanism, and electromagnet is as slide block mechanism.Anti-fall bearing plays the effect of fixing anti-fall hook, and can also limit the movement travel of anti-fall hook.In the time that haulage cable or chain rupture suddenly, slack rope (chain) testing agency of equipment sends signal, electromagnet reception control signal, as shown in Figure 3, electromagnet 5 power-off, electromagnet head extends, release force, the connecting rod being connected with electromagnet moves laterally, connecting rod other end and anti-fall hook are hinged, circular hole on anti-fall hook is connected with the spring on anti-fall bearing, because spring is stretched when the work of electromagnet, after electromagnet power-off, spring is replied deformation, under the effect of spring tension, anti-fall hook is around bearing upper pin 3 central rotations, after revolution certain angle, anti-fall hook one lateral edges is encountered block 1 upside (as figure five) on bearing, anti-fall hook stops operating, position is fixed to as shown in Figure 3, because haulage cable or chain rupture suddenly, lifting table declines rapidly, now anti-fall hook is encountered the block (spacing of block can be set as required) on steel structure, lifting table motion is obstructed, stop declining, for avoiding anti-fall hook to come off because of impact force action and anti-fall bearing, on anti-fall bearing, be provided with block 2, under anti-fall hook mode of operation, it is protected to (as figure five), the combined action of whole mechanism, guarantee the safety of operational process, avoid pendant car, pound the danger of car,
And in the time that mechanism is normally used, slack rope (chain) testing agency sends the signal of normal work, electromagnet 5 receives signal, electromagnet obtains electric work, electromagnet head is retracted, under the effect of electromagnet pulling force, the connecting rod 4 being connected with electromagnet is tightened up, connecting rod pulls the anti-fall hook of its opposite side, anti-fall hook overcomes spring tension, bearing pin 3 on anti-fall bearing rotates, after rotating to an angle, sideline, anti-fall hook left side contacts with the right side edge of the block 1 on bearing, anti-fall hook position is fixed, avoid the stop location (as figure tetra-) on steel structure, lifting table can be gone up in orbit, lower free-running operation.
Dynamically falling proof device can be in the time that haulage cable or chain rupture suddenly, and protection lifting table is parked near position, the danger of avoided pendant car, pounding car; And under the state of the normal operation of mechanism, can not produce with other mechanisms again and interfere, guarantee the normal work of mechanism.
Electromagnet only need to be installed on lifting table by this mechanism, just can in whole hoist trunk, realize dynamically anti-fallly, and cost is low; Compact conformation, small and exquisite, installation site is flexible, and it is convenient to change; There is multiple protector, safe and reliable; Novel form, can be widely used in the lifting devices such as mechanical three-dimensional parking device.
