Abstract
The utility model discloses a crash preventing device for breaking rope protecting and door opening self-locking of material elevators. The crash preventing device is designed for aiming at the defects of generally used telescopic pin type, turning plate hanging rack type and sawtooth surface clamping mouth type crash preventing devices. The utility model is characterized in that the crash preventing device prevents crash by friction force between a wedge body sliding block and a lifting rack guiding rail, wherein, the wedge body sliding block is installed on a floating plate and forms a floating plate component with a wedge seat, a hinge connecting rod, a rocker arm gear, a hollow gear rack, etc.; one end of the floating plate component is connected with upright post on both sides of a hanging basket by a supporting shaft; the other end of the floating plate component is connected with the lifting rack guiding rail by a guiding wheel and is connected with a turning door of the hanging basket by a supporting seat, a supporting rod, a bending plate, a draw rod, etc. The utility model not only overcomes the defects generated by telescopic pins, turning plate hanging racks and sawtooth surface clamping mouths, but also enlarge the contact surface between the wedge body and the guiding rail, can not damage the guiding rail, also increases the stability of the hanging basket and the reliability of the crash preventing device and can be used for various gantry rack type, well rack type and single rod type material elevators.
Description
Technical field: the utility model relates to a kind of safety guard that is used for material elevator.
Background technology: at present, in building operation, the hanging basket anti-fall device that is used for various material elevators has flexible pin formula, turnover panel hanging frame type, serrated face folder to chew multiple structures such as formula, yet, facts have proved that they all exist such or such defective, used easy bending of a specified duration such as flexible pin, the turnover panel hanger can make support body bar joint impaired under heavy duty, the serrated face folder is chewed the embedding guide rail, and guide rail attenuate rigidity is weakened, or the like.That Chinese patent ZL97224205.8 once disclosed was a kind of " simplified elevator breaking rope protecting, the self-locking anti-fall device opens the door "; pass through interlocking gear; the friction force that utilizes wedge slide block and guide rail to produce realizes that disconnected rope is anti-fall and stop self-locking, facts have proved that this device also has weak point.Such as the clamshell doors of anti-fall interlocking gear, if do not shut, in time, scrapes a phenomenon and takes place when operation; Especially damage suddenly and can not glancing impact when the fast winch band-type brake owing to there is disrumpent feelings steel rope can force reel that rotation takes place oppositely to quicken than large traction, hanging basket because of can not speed limit sharply decline cause the big and heavy stone basket.
Summary of the invention:
The purpose of this utility model is; at above-mentioned defective, a kind of material elevator safety guard is provided, it is when realizing that hanging basket breaking rope protecting, the self-locking of opening the door are anti-fall; not only can stop to scrape a phenomenon, the big and heavy stone basket accident that especially can avoid causing owing to the winch band-type brake is malfunctioning takes place.
Technical solution of the present utility model is: a kind of material elevator breaking rope protecting, the self-locking anti-fall device opens the door; comprise the hanging basket that the winch rope is connecting by raising legs; and the wedge slide block and the wedge block that are connecting by interlocking gear, spring, rod member etc.; it is characterized in that: wedge slide block and wedge block are installed on the float plate; form the float plate assembly with miscellaneous part; this float plate assembly one end connects by the column of pivot shaft and hanging basket both sides, and the other end links with the raising legs guide rail by leading the boots wheel.
The said float plate assembly in front, its main body is the float plate that a middle part has elongate slots, the elongate slots both sides are to be the wedge block that has dovetail furrow that " eight " font is laid, the wedge slide block is embedded in the dovetail furrow, its underpart is connected with rocker gear by the hinge connecting rod, and the rocker gear axle is installed on the float plate; Elongate slots is stretched out in the pivot shaft termination, fixes a hollow rack on it, and tooth bar is meshed with rocker gear; In addition, be provided with stage clip in tooth bar is hollow, be provided with stage clip by spring perch perpendicular to pivot shaft at the float plate back side, float plate is positive and be provided with and lead the boots wheel.Here said wedge is sliding to be arcwall face, and arcwall face is provided with anchor wire.
In addition, can connect a push rod by a bearing, and be connected the door of digging of hanging basket by bent plate with pull bar in the float plate lower end.Can also add an emergent spanner by two trundles between the bearing of float plate lower end and push rod, the fulcrum pin axle of this emergent spanner is fixed on the column of hanging basket
Compared with prior art, the utlity model has following advantage:
(1) because existing clamshell doors is dug door instead, so as long as just can realize stopping self-locking in case door is dug hanging basket, just be opened and continue operation and have only, therefore not only guaranteed the safety stop of hanging basket, and avoided scraping a phenomenon and take place when door being turned over when falling the hanging basket self-locking.
(2) owing to adopt the float plate unit construction, the boots wheel of leading on the assembly is done perpendicular movement along the raising legs guide rail, operation under normal circumstances has no to hinder, and the malfunctioning hanging basket that makes of in a single day disconnected rope or winch band-type brake exceeds the speed limit when falling, the pivot shaft that is fixed on hanging basket two heel posts and puts in the float plate elongate slots will descend thereupon, driving tooth bar simultaneously moves down, and promote the wedge slide block is done spot speed in wedge block upward movement by rocker gear and hinge connecting rod, rely between the arcwall face of wedge slide block and anchor wire in the riveted joint and raising legs guide rail friction force to embrace the raising legs guide rail inflexibly, reach and prevent the hanging basket purpose of falling.This moment, load carrying ability was big more, and the locking braking force is big more.And adopt arcwall face wedge slide block and rivet the anchor wire measure, not only can overcome flexible pin, turnover panel hanger and serrated face folder and chew all defect that is produced, and increased contact surface between wedge and the guide rail, not only guide rail be can not damage, and the stability of hanging basket and the reliability of device increased.
(3) in addition, consider installation and maintenance personnel's operation needs, below float plate, added emergent spanner.Like this, when in a single day they feel that in operation the hanging basket downslide is fallen possibly, the emergent spanner of can wrenching is immediately realized and is made pivot shaft move down same technique effect by making to move on the float plate, promptly by making wedge slide block upward movement realize the safety stop of hanging basket.This point is the same with the principle of work of digging door.
