Abstract
The utility model discloses a rushing-prevention protection device for a pulley frame of a split hoisting sheave device. The protection device comprises a connecting rod, a collision block and a travel switch, wherein one end of the connecting rod is rotatably arranged at the top end of the pulley frame of a hoisting sheave, a roller is arranged at the other end of the connecting rod and is in rolling contact with a vertical pipe of a guiderail frame, the collision block is further hung between the two ends of the connecting rod, the travel switch is arranged at the position of a transmission frame corresponding to the collision block, the transmission frame is below the pulley frame of the hoisting sheave, and the travel switch is electrically connected with a lifting motor. The rushing-prevention protection device for the pulley frame of the split hoisting sheave device is simple in structure, convenient in installation, low in cost and good in use effect.
Description
Technical field
The utility model relates to a kind of split type day anti-over-hoisting protection device of wheel apparatus apparatus for suspension.
Background technology
SCD/SC type building hoist is a kind of lifting construction machinery and equipment that adopts the transmission of rack-and-gear form; People's goods vertical transport when being mainly used in high-building construction or other similar applications has easy accessibility, operates steadily, advantage such as simple to operate, safe and reliable.
Need not separate the advantage of day wheel apparatus when the elevator of split type day wheel apparatus has guide rail bracket jacking supernumerary segment, avoid the elevator of integral type sky wheel apparatus when the jacking supernumerary segment, need dismantle, lift the trouble of day wheel apparatus.Therefore the application of wheel apparatus on building hoist in split type day more and more widely.But split type sky wheel apparatus easily because of carelessness (or maloperation), causes the head sheave apparatus for suspension to go out guide rail bracket in guide rail bracket jacking supernumerary segment process, exists potential safety hazard.
The utility model content
The utility model technical matters to be solved is to overcome deficiency of the prior art and a kind of simple in structure, easy for installation, with low cost, result of use is good split type day anti-over-hoisting protection device of wheel apparatus apparatus for suspension is provided.
The technical scheme that the utility model solves the problems of the technologies described above employing is: this split type day anti-over-hoisting protection device of wheel apparatus apparatus for suspension; Be installed on the head sheave apparatus for suspension; It is characterized in that: comprise connecting rod, collision block and travel switch, described connecting rod one end rotates and is arranged on head sheave apparatus for suspension top, and the connecting rod other end is equipped with roller; Roller and guide rail bracket standpipe rolling touch; The collision block that also has been hung between the two ends of connecting rod is provided with travel switch with the corresponding position of collision block on the gear frame of head sheave apparatus for suspension below, and travel switch is electrically connected with lifting motor.
Described head sheave apparatus for suspension of the utility model and the corresponding position of collision block are provided with the collision block track, and collision block is slidingly arranged in the collision block track.
Described collision block one end of the utility model is hung on the connecting rod through steel rope, and the collision block other end passes the collision block slide and is arranged in the collision block track.
Described collision block of the utility model and steel rope bonded assembly one end are fixed with an iron plate, and iron plate is wider than the gap between collision block and the collision block track.
The utility model compared with prior art has the following advantages: connecting rod is equipped with roller one end and must be higher than head sheave apparatus for suspension roller installation position in the utility model; And roller can roll at guide rail bracket standpipe active component; In case roller is gone out guide rail bracket, can be after soaring because the weight of collision block is toward dropping, outage made cage stop to continue to rise after collision block touched travel switch; Thereby prevent that the head sheave apparatus for suspension from going out the guide rail bracket standpipe, stop safety misadventure.
Description of drawings
Fig. 1 is the utility model head sheave apparatus for suspension sectional view.
Fig. 2 triggers the travel switch scheme drawing for the tenesmus of the utility model collision block.
The specific embodiment
Referring to Fig. 1 and Fig. 2; Comprise connecting rod 1, collision block 2 and travel switch 3; Described connecting rod 1 one ends rotate and are arranged on head sheave apparatus for suspension 5 tops (joint standpipe or tooth bar place are near the mark); Connecting rod 1 other end is equipped with roller 6, and connecting rod 1 is equipped with roller 6 one ends must be higher than head sheave apparatus for suspension 5 roller installation positions.Roller 6 and guide rail bracket standpipe 9 rolling touch, the collision block 2 that also has been hung between the two ends of connecting rod 1 is provided with travel switch 3 with collision block 2 corresponding positions on the gear frame 7 of head sheave apparatus for suspension 5 belows, and travel switch 3 is electrically connected with lifting motor (figure is last not to be seen).Head sheave apparatus for suspension 5 is provided with collision block track 8 with collision block 2 corresponding positions, and collision block 2 one ends are hung on the connecting rod 1 through steel rope 4, and collision block 2 other ends pass collision block track 8 and are slidingly arranged in the collision block track 8.Collision block 2 is fixed with an iron plate 10 with steel rope 4 bonded assemblys one end, and iron plate 10 is wider than the gap between collision block 2 and collision block rail 8 roads.Under the situation of steel rope 4 disconnected ropes, this iron plate 10 may be stuck on the collision block track 8, thereby prevents the collision block tenesmus.
In the jacking supernumerary segment process, be in guide rail bracket standpipe 9 like head sheave apparatus for suspension 5 and gone up most in limited time, because human negligence (or maloperation); Cage continues to withstand a day wheel mechanism upward movement, and this moment, roller 6 one ends of connecting rod 1 were gone out guide rail bracket standpipe 9 before the roller of head sheave apparatus for suspension 5, because the effect of collision block 2 weight; Connecting rod 1 around bearing pin to lower swing; Collision block 2 positions descend, and have triggered travel switch 3, make its action and outage; Cage is out of service, thereby prevents that head sheave from going out guide rail bracket because of continue rising.
Above content described in this specification sheets only is the casehistory that the utility model structure is done.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
