Abstract
An anti-top-collision device used on a lifter relates to the lifter. A fixing support, a guiding screw bolt, a spring, a bearing assembly and a travel switch are arranged on the anti-top-collision device. The fixing support is fixedly connected with the topmost end of a transmission rack of the lifter through a bolt; the guiding screw bolt and the travel switch are fixed on the fixing support; the screw bolt is sheathed with the spring; the bearing assembly is installed at the tail end of the guiding screw bolt and can slide in the shaft axis direction of the guiding screw bolt; a bearing in the bearing assembly is in close contact with the back side of a gear rack on a guide rail rack of the lifter, and compresses the spring; and the bearing assembly compresses a contact point of a limit switch, so as to ensure that a circuit of a driving motor is switched on. When the anti-top-collision device is used, the bearing rushes out of the gear rack first when the lifter in construction acts top collision, the bearing assembly is pushed to move outwards under the action of the spring, the travel switch is triggered so as to lead the driving motor to be powered off, the lifter stops operating, and sequentially the top collision can be avoided. The anti-top-collision device is convenient to disassemble and assemble and is effective and reliable in practice.
Description
Technical field
The utility model relates to a kind of elevator, especially relates to a kind of erosion control ejection device that is used for elevator.
Background technology
The erosion control ejection device seldom is installed on the existing building hoist.
Chinese patent CN201406237 discloses a kind of elevator erosion control ejection device, comprises box body, pinch roller, retracing spring, movable block, slide block, wheel shaft, spring pull bar, spring stop, the catch of travel switch, guide rod, double as pressing plate; Pinch roller is pressed on the guide rod on the elevator guide rails frame limit, and square box body middle part is provided with spring stop, square movable block, and wheel shaft stretches into space in the box body; The spring catch wooden partition is provided with tie rod hole, and the spring pull bar passes tie rod hole captives joint with the movable block side; Retracing spring is located at the spring pull bar periphery between catch and spring stop; Travel switch is located at the movable block back side, and its contact is near inboard wall of cartridge.Because travel switch and pressing plate are located in the box body on the cage, action retracing spring when putting in place promotes the movable block action, can directly not be subjected to strong physical shock, reliable in action, when rising layer, building both do not moved the installation pressing plate again, do not readjust yet, can prevent from that maloperation from causing to rush to summit, and be applicable to rack-and-gear driving type elevator.
Chinese patent CN2189142 discloses the anti-safety device of rushing to summit of a kind of well cabinet frame elevator, is made up of screw mandrel, collision block, travel switch etc.Screw mandrel is installed on the drum shaft of winch, collision block and screw mandrel are screw thread fit, when winch starts, when driving cage and rise by steel rope, screw mandrel also rotates synchronously with the lifting drum axle, collision block is moving along the screw mandrel translation, bumps when carrying out the journey switch contact travel switch open circuit when collision block moves to, cut off the electricity supply, winch stall and braking, cage rises and to stop, thereby prevents that cage from rushing to summit.
Chinese patent CN2294244 discloses a kind of elevator erosion control ejection device, it comprises cutout relay, feature is that the underframe of cutout relay is fixed on the guide rail bracket bottom, touching lever one end is connected with the switch turning cylinder of cutout relay, the switch of control cutout relay, the other end is equipped with roller, and roller stretches in the orienting sleeve, steel rope passes orienting sleeve from the centre, and movable collision block is clamped on the steel rope of orienting sleeve top with bolt.Movable collision block enters in the orienting sleeve when moving downward, and bumps roller and touching lever, and touching lever touches the switch in the cutout relay, cuts off the winch power supply, thereby prevents that cage from rushing to summit.
Summary of the invention
The purpose of this utility model is to provide a kind of erosion control ejection device that is used for elevator.
The utility model is provided with fixed support, guide spiro rod, spring, bearing external member and travel switch.Fixed support is connected the elevator gear frame topmost with bolt, guide spiro rod and travel switch are fixed on the fixed support, spring housing is on screw rod, the bearing external member is installed in the terminal of guide spiro rod and can slides along the direction of axis line of guide spiro rod, tooth bar back side closed contact and holddown spring on bearing in the bearing external member and the elevator guide rails frame, the bearing external member compresses the limit switch contact, guarantees that the circuit of drive motor is in on-state.
During use, when building hoist was rushed to summit action, the bearing in the utility model was at first gone out tooth bar, because of action of the spring impeller-hub bearing sleeve spare outwards moves, triggered travel switch, made the drive motor outage, and elevator stops operation, avoids rushing to summit.
The utility model in actual use, easy accessibility, and effectively reliable, because of bearing along the tooth bar rolling touch, the entire mechanism maintenance is convenient, by the mild action triggering travel switch of bearing external member, does not have strong physical shock or excessive stroke because of just, fault rate is low.Whether the utility model is directly installed on the extreme higher position of elevator movable parts (gear frame and cage), directly embody elevator craning cage and rush to summit, and is safe and reliable.
Description of drawings
Fig. 1 is that the three-dimensional structure of the utility model embodiment is formed scheme drawing.
Fig. 2 faces structure for the two dimension of the utility model embodiment and forms scheme drawing.
The specific embodiment
Following examples will be further described the utility model in conjunction with the accompanying drawings.
Referring to Fig. 1 and 2, the utility model embodiment is provided with fixed support 1, guide spiro rod 2, spring 3, bearing external member 4 and travel switch 5.Fixed support 1 usefulness bolt is connected the elevator gear frame topmost, guide spiro rod 2 and travel switch 5 are fixed on the fixed support 1, spring 3 is enclosed within on the screw rod 2, bearing external member 4 is installed in the terminal of guide spiro rod 2 and can slides along the direction of axis line of guide spiro rod 2, tooth bar back side closed contact on bearing in the bearing external member 4 and the elevator guide rails frame and holddown spring 3, bearing external member 4 compresses the limit switch contact, guarantees that the circuit of drive motor is in on-state.
During use, when building hoist was rushed to summit action, the bearing in the utility model was at first gone out tooth bar, because of action of the spring impeller-hub bearing sleeve spare 4 outwards moves, triggered travel switch 5, made the drive motor outage, and elevator stops operation, avoids rushing to summit.
