Abstract
The utility model discloses an anti-falling safety device for an electric hoist. The anti-falling safety device for the electric hoist comprises a driving wheel side safety reverse hook and a driven wheel side safety reverse hook which are symmetrically installed on the outer side of an electric hoist driving running wheel and on the outer side of an electric hoist driven running wheel, wherein the two safety reverse hooks are both adhered to supports on corresponding sides of the running wheels and are installed through connection pins on the electric hoist. Plate hooks are arranged on the two safety reverse hooks, and the hoist colloids with and is in surface contact with buffers on two sides of a main beam when running to two ends of the main beam. The anti-falling safety device for the electric hoist makes up for the defect that the existing electric hoist is not provided with the anti-falling safety device, and the buffers are seriously abraded. The anti-falling safety device for the electric hoist is simple in structure, convenient to install, and capable of safely and reliably preventing the electric hoist from falling caused by obliquely pulling operation or looseness and breakage of running wheel shafts and an overlarge gap between the running wheels and a main beam web and reducing abrasion of the buffers.
Description
Technical field
The utility model belongs to elevator machinery, relates to a kind of electric block falling-proof safety device.
Background technology
Present employed electric block all is not provided with falling-proof safety device; When electric block is in when tiltedly drawing the position operation; If tiltedly draw the big or operation wheel shaft of angle to get loose, rupture and when move wheel and girder web excessive clearance; Hang on as easy as rolling off a log the falling of electric block on the crane girder, have very big potential safety hazard, in case cucurbit falls causing very serious safety misadventure.Show that according to related data present cucurbit falling accident also happens occasionally.Simultaneously, when cucurbit moved to the girder two ends, the operation wheel rim or the operation wheel gear teeth collided with the energy disperser that is installed on the girder two ends, and the energy disperser that bites causes the energy disperser wearing and tearing very serious.
The utility model content
The utility model is to the deficiency of existing electric block existence in service, and a kind of safe and reliable to operation, simple in structure, easy for installation, electric block falling-proof safety device that the energy disperser wearing and tearing are little is provided.
The described electric block falling-proof safety device of the utility model; It comprises that symmetry is installed in the anti-hook of driving wheel side safety, the anti-hook of follower side safety that electric block initiatively moves the wheel outside and the passive operation wheel outside; All the recline operation wheel support of side of the anti-hooks of two safety is through the connecting pin axle mounting on the electric block.
The anti-hook of said driving wheel side safety comprises riser, strengthens gusset and plate hook; The quantity of plate hook is two, vertically is arranged symmetrically in the two ends of riser perpendicular to riser, strengthens gusset connecting panel hook and riser; Riser upper edge shape is consistent with the bottom profiled of this side operation wheel and operation motor, and connecting pin shaft position place on corresponding electric block, riser bottom offers the corresponding mounting hole; The anti-hook of said follower side safety is pressed the anti-hook symmetry of driving wheel side safety and is made, but the shape of riser upper edge is consistent with this side operation wheel bottom profiled.
Said plate hook is the oblong steel plate of one jiao of gap.
The utility model is made up of anti-hook of driving wheel side safety and the anti-hook of follower side safety; Being installed on electric block through the mounting hole on the anti-hook riser of both sides safety connects on the bearing pin; The riser two ends of the anti-hook of both sides safety all are provided with plate hook, and when electric block tiltedly draws operation and tiltedly draws angle big or the operation wheel shaft gets loose, ruptures and when move wheel with girder web excessive clearance, operation is taken turns and skidded off girder bottom wing listrium or cucurbit directly falls; At this moment; Plate hook firmly tangles girder bottom wing listrium, guarantees that safely and reliably cucurbit does not fall, and avoids taking place safety misadventure.The plate hook face contacts with face with energy disperser when cucurbit moves to the girder two ends and collides with energy disperser in addition, has reduced the wearing and tearing of energy disperser.

The specific embodiment
Embodiment one, and the utility model is installed on the girder that the cross section is a rectangle.Like Fig. 1,3,4,5, shown in 6; The utility model comprises that symmetry is installed in electric block and initiatively moves wheel 5 outsides and passive operation and take turns the anti-hook of the driving wheel side safety in 2 outsides 7, the anti-hook 6 of follower side safety; All the recline operation wheel support 1 of side of the anti-hooks of two safety is installed through the connection bearing pin on the electric block 3.The anti-hook 7 of driving wheel side safety comprises riser 71, strengthens gusset 72 and plate hook 73; The quantity of plate hook 73 is two; Vertically be arranged symmetrically in the two ends of riser 71 perpendicular to riser 71; Strengthen gusset 72 and connect plate hook 73 and riser 71, breach is offered in the lower right corner of plate hook 73, and the gap width size is greater than the width at girder 8 bottom wing listrium supported on both sides operation wheel place; Riser 71 upper edge shapes are consistent with the bottom profiled of this side operation wheel and operation motor, and riser 71 bottoms connect bearing pin 3 positions and offer the corresponding mounting hole 74 on corresponding electric block; The anti-hook 6 of follower side safety is pressed anti-hook 7 symmetries of driving wheel side safety and is made, but the shape of riser 61 upper edges is consistent with this side operation wheel bottom profiled.
During installation; Respectively the anti-hook of driving wheel side safety 7, the anti-hook 6 of follower side safety being sleeved on electric block through the mounting hole on it 74 connects on the bearing pin 3; Make the anti-hooks of the two safety cucurbit operation wheel support 1 that reclines then; The web, bottom wing listrium that guarantee end, hook face and the crane girder 8 of plate hook 73 simultaneously keep certain distance, to guarantee electric block normally operation on girder 8, at last with connecting on the bearing pin 3 original nut 4 with its locking.
Electric block is not in when tiltedly drawing operation; The utility model is with electric block smooth running on girder 8; When electric block tiltedly draws operation and tiltedly draws angle big or the operation wheel shaft gets loose, ruptures and when move wheel and girder web excessive clearance; Bottom wing listrium or cucurbit that the operation wheel can skid off girder 8 directly fall, and the plate hook 73 on the anti-hook 7,6 of operation this moment wheel both sides safety firmly tangles the bottom wing listrium of girder 8, guarantees that safely and reliably electric block does not fall.
Embodiment two, and it is on the double-tee girder 8 that the utility model is installed in the cross section, and principle safe and reliable to operation is with embodiment one.
