Abstract
The utility model provides an anti-falling device for a suspension cage of a construction lifter, which is characterized in that a pulley of a main wire cable of the suspension cage of the lifter is connected with a rotating frame, the rotating frame is supported by a suspension cage supporting seat, and the lower portion of the suspension cage supporting seat is connected with a steel plate. One end of the steel plate is in overlap joint with one end of the rotating frame, one end of the rotating frame is connected with a connecting rod which is connected with a first brake rod, and the first brake rod is connected with a second brake rod through a rotating shaft. The rotating shaft is fixed on a lug plate of the suspension cage, the second brake rod is further connected with a stopping ratchet, and the upper portion of the stopping ratchet is provided with a positioning shaft. The anti-falling device for the suspension cage of the construction lifter is rigorous in structure, flexible in stopping, stable in quality, safe and reliable and has wide application value in safe anti-falling of suspension cages of various lifters.
Description
Technical field
The utility model relates to the weight-lifting equipment technical field, specifically a kind of building hoist cage falling-proof device.
Background technology
Existing cage falling-proof device adopts anti-fallly with the subsequent use steel cable of cage synchronization lifting, and after main steel rope broke off for some reason, the traction of cage was displaced on the subsequent use anti-fall steel cable immediately, and the cage of tenesmus is rested on the guide rail bracket.Anti-drop system is by subsequent use steel cable, large pulley, anti-fall case are formed up and down.Because of subsequent use steel cable needs and the running of cage synchronization lifting, steel cable, pulley are easy to wear, and maintenance cost is high; Anti-fall driving system is independent closed box, and manufacturing cost is high; Anti-fall case surpasses to be stipulated tenure of use, and need integral replacing, it is big to upgrade cost.
The utility model content
The purpose of the utility model provides a kind of building hoist cage falling-proof device, and transportation, easy to use has greatly reduced manufacturing and maintenance cost, has improved safe reliability.
The technical scheme of the utility model is: on the pulley of elevator craning cage main steel rope, connect swivel mount, swivel mount is by the cage bearing support, and cage bearing bottom connects steel plate; One end of this steel plate and an end of swivel mount overlap joint, an end of swivel mount connects connecting rod, and connecting rod connects brake rod one; Brake rod one is connected with brake rod two through rotating shaft; This rotating shaft is fixed on the cage otic placode, and brake rod two is connected with the stop ratchet again, and the top of stop ratchet is provided with a fix shaft.
Anti-fall device of the utility model and building hoist main frame consubstantiality are manufactured, and anti-fall steel cable, large pulley have up and down been cancelled in transportation, easy to use, and the consumable accessory stop ratchet of maintenance is convenient to change, and whole anti-fall device has greatly reduced manufacturing and maintenance cost.This anti-fall device is of a tightly knit structure, stop is sensitive, and steady quality is safe and reliable.To the anti-fall value that is widely used of the safety of all kinds of gig cages.
Description of drawings
Fig. 1 is the structural representation of the building hoist cage falling-proof device of the utility model.
Among the figure, 1, main steel rope, 2, steel plate, 3, swivel mount, 4, connecting rod, 5, rotating shaft, 6, brake rod one, 7, brake rod two, 8, fix shaft, 9, the stop ratchet, 10, the cage bearing, 11, the cage otic placode.
The specific embodiment
As shown in Figure 1, the building hoist cage falling-proof device of the utility model is on the pulley of elevator craning cage main steel rope 1, to connect swivel mount 3 with bearing pin, and swivel mount 3 is by bearing pin connection cage bearing 10 and by its supporting; Cage bearing 10 bottoms connect a steel plate 2 by bearing pin, an end of this steel plate and an end of swivel mount 3 overlap joint, and an end of swivel mount 3 connects connecting rod 4 by bearing pin; Connecting rod 4 connects brake rod 1 by bearing pin; Brake rod one is connected with brake rod 27 through rotating shaft 5, and brake rod two is connected with stop ratchet 9 by bearing pin again, and rotating shaft 5 is fixed on the cage otic placode 11; The top of stop ratchet 9 is provided with a fix shaft 8, and fix shaft 8 is welded on the cage.
Principle of work:
Main steel rope breaks off for some reason; Steel plate 2 makes on swivel mount 3 front ends and moves, and connecting rod 4 drives rotating shaft 5 rotation set angles, and brake rod two moves stop ratchet 9 under fix shaft 8 controls; Stop ratchet 9 and elevator guide rails frame channel-section steel side moment locking stop are on the cage safety stop guide rail bracket.
