Abstract

The utility model discloses a device for floor-stop for construction elevators, which is mainly composed of a positioning mechanism and buffering pause layer stop dogs, wherein, the buffering pause layer stop dogs are arranged on hanging cage guide rails, and the buffering pause layer stop dogs are positioned corresponding to a positioning rod, and furthermore, the positioning mechanism is composed of a carrier frame, electromagnetic coils, electric magnet blocks, a restoring spring, a connecting rod and a positioning rod. Because electromagnetic floor-stop structure is adopted by the utility model, the utility model has the advantages of simpler structure, better reliability and higher safety.

Description

The building hoist floor stopper

The utility model relates to a kind of layer falling-proof safety device that stop, and particularly relates to a kind of building hoist floor stopper.

The floor stopper of building hoist belongs to building operation with the auxiliary facility of elevator, and it is to make it steadily stop design-calculated for the automatic guidance elevator craning cage after rising to the desired location.What China's utility application numbers 93233291 disclosed a kind of arch type lifter stops floor rack unit automatically, it is by elevator guide rails frame, cage raceway, moveable hinge pole, shelf pipe, hinged-support pipe and stop a layer shelf and form, utilize the shelf pipe on the cage raceway rolling and the motion of moveable hinge pole control elevator craning cage stop automatically put.Since this floor stopper be adopt that mechanical connection mechanism realizes cage stop layer automatically, its structure is comparatively complicated and to stop the reliability of layer relatively poor.

The purpose of this utility model just provides a kind of safety, the better lift bed device of anti-skidding and anti-fall property.

In order to achieve the above object, the utility model building hoist floor stopper is to stop a layer block by detent mechanism and buffering to constitute, buffering is stopped the corresponding position that layer block is installed in radius stay, and described detent mechanism is to be made of carriage, magnet coil, electromagnet block, retracing spring, bar, radius stay.Magnet coil is socketed on the electromagnet block, and electromagnet block is fixed on the carriage, and an end of electromagnet block connects connecting rod, the other end of connecting rod connects radius stay, retracing spring is socketed on the connecting rod, and the other end of retracing spring is fixed on the carriage, and radius stay is slidingly connected in the pilot hole of carriage.

Because the utility model adopts electromagnetism to stop a layer structure, structure is more simple, better reliability, and safety is higher.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is the front view of the utility model building hoist floor stopper;

Fig. 2 be the utility model building hoist floor stopper along C to partial schematic diagram.

As shown in Figure 1 and Figure 2, the utility model building hoist floor stopper is to stop layer block 2 by detent mechanism 1 and buffering to constitute.Buffering is stopped layer block 2 and is installed on the cage guide rail 4, is positioned at the corresponding position of detent mechanism 1 radius stay 16.Detent mechanism 1 is to be made of carriage 15, magnet coil 11, electromagnet block 12, retracing spring 13, bar 14, radius stay 16, magnet coil 11 is socketed on the electromagnet block 12, electromagnet block 12 is fixed on the carriage 15, one end of electromagnet block 12 connects connecting rod 14, the other end of connecting rod 14 connects radius stay 16, retracing spring 13 is socketed on the connecting rod 14, and the other end of retracing spring 13 is fixed on the carriage 15, and radius stay 16 is slidingly connected in the pilot hole 151 of carriage 15.

When cage 5 stops layer, Dump gate 3 is opened, be installed in the limit switch outage on the Dump gate 3, magnet coil 11 in the detent mechanism 1 that is attached thereto is also cut off the power supply, magnetic field diminishes, connecting rod 14 promotes radius stay 16 under the effect of retracing spring 13 protruding, is shelved on the buffering that is installed on the cage guide rail 4 and stops layer block 2, realizes stopping layer.Otherwise, Dump gate 3 is closed, be installed in the limit switch energising on the Dump gate 3, make be attached thereto magnet coil 11 also switch on, generate an electromagnetic field, electromagnet block 12 is shunk, drivening rod 14 shrinks, connecting rod 14 drives radius stay 16 and inwardly shrinks, and makes radius stay 16 and buffering stop layer block 2 and separates, and 5 of cages can continue operation.

Claims

1, a kind ofly stops the building hoist floor stopper that layer block constitutes by detent mechanism and buffering, buffering is stopped the corresponding position that layer block is installed in radius stay, and it is characterized in that: described detent mechanism is to be made of carriage, magnet coil, electromagnet block, retracing spring, bar, radius stay; Magnet coil is socketed on the electromagnet block, and electromagnet block is fixed on the carriage, and an end of electromagnet block connects connecting rod, the other end of connecting rod connects radius stay, retracing spring is socketed on the connecting rod, and the other end of retracing spring is fixed on the carriage, and radius stay is slidingly connected in the pilot hole of carriage.
