Abstract
The utility model relates to a two push away electro-magnet brake utensils release handle, its structure includes the inserted bar and turns round the handle, is equipped with the plectrum at the front end of inserted bar cup joint the return spring who is used for popping out the frame jack with the inserted bar part on the inserted bar. The utility model discloses can make the brake release handle be in the half inserted state in the stopper frame under the normality, when the action of turning round the handle as unexpected touching or scraping takes place, even take place to turn round the handle and drive the inserted bar pivoted condition and take place, do not have the plectrum yet and stir the electro-magnet and cause the stopper to loosen the floodgate, the stable state of double push electromagnet stopper and elevator or hoisting equipment's safety has been ensured from this, the elevator or the crane that have avoided stopper to loosen the floodgate maloperation to cause arouses the serious consequence of falling ladder or falling machine, and the emergence of the loss brake release handle condition that has brought has also been placed in the separation of brake release handle and stopper.
Description
Technical Field
The utility model relates to a two push-out electromagnetic brake, specifically speaking are two push-out electromagnetic brake are with breaking handle.
Background
The double-push electromagnet brake is provided with a brake releasing handle so as to pull out two mutually attracted electromagnets in the brake during maintenance. The brake releasing handle comprises an inserted bar and a twisting handle connected to the rear end of the inserted bar, and a shifting piece is arranged at the front end of the inserted bar. The inserted link of the brake release handle is inserted into the jack of the brake base, and the twisting handle is radially inserted and fixed at the rear end of the inserted link. The shifting sheet is positioned in a gap between the two electromagnets. When the brake needs to be released, the twisting handle on the brake releasing handle is pulled, the inserted bar rotates along with the twisting handle, and the shifting piece at the front end of the inserted bar can shift the two electromagnets away, so that the brake releasing purpose of the brake is realized.
The twist grip on the brake release handle is long and exposed above the brake, so that the twist grip is easily touched or scraped by the limbs of a maintenance worker. The touch and scratch due to the non-subjective factors easily cause the brake release misoperation of the brake. In case of accidental brake release without releasing the brake, the elevator or the crane will inevitably cause a serious accident of falling down. The brake release handle and the brake are separately placed, so that the brake release misoperation can be avoided, but the brake release handle is easily lost on site as a result of separately placing the brake release handle, and once the brake release handle is lost, the emergency repair of the elevator or hoisting equipment can be delayed, so that the elevator can be recovered to be normally operated or the crane can be normally operated to bring large or even serious adverse effects.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a two push-button electromagnetic brake utensils brake release handle to solve the not good problem of settling of brake release handle on the stopper.
The utility model discloses a realize like this: the utility model provides a two push away electro-magnet brake utensils release handle, includes inserted bar and twist the handle, is equipped with the plectrum at the front end of inserted bar the return spring that is used for popping out the inserted bar part in the frame jack has been cup jointed on the inserted bar.
The plug rod is provided with a reducing section in a turning mode, the return spring is sleeved on the reducing section, gaskets are respectively sleeved on the reducing sections at the front end and the rear end of the return spring, and the gaskets at the rear end of the return spring are limited by check rings clamped on the plug rod.
The utility model discloses an install return spring additional on the brake release handle, can be so that the brake release handle is in the half inserted state in the stopper frame under the normality, this moment, the plectrum of inserted bar front end is the position department outside being located two electro-magnet gaps of stopper, when the action of twisting the handle takes place in unexpected touching or scraping, even take place to twist the handle and drive the inserted bar pivoted condition and take place, do not have the plectrum yet and stir the electro-magnet and cause the stopper to loosen the floodgate, the stable and elevator or hoisting equipment's of state of double push-off electro-magnet stopper safety has been ensured from this, the elevator or the serious consequence that the hoist arouses weight ladder or weight machine that brake release maloperation caused has been avoided, and the emergence of the lost brake release handle condition that has also avoided brake release handle and the separation of stopper to place and bring, can not cause the delay of elevator or hoisting equipment salvage.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the installation structure of the double-push electromagnet brake of the present invention.
Fig. 3 is a partially enlarged view of a portion a in fig. 2.
In the figure: 1. the device comprises an insertion rod, 2 a twisting handle, 3 a shifting sheet, 4 a return spring, 5 a gasket, 6 a gasket, 7 a retainer ring, 8 a base, 9 and an electromagnet.
Detailed Description
As shown in fig. 1-3, the utility model discloses an inserted bar 1 and twist handle 2, twist handle 2 and peg graft in the radial jack of inserted bar 1 rear end to realize that inserted bar 1 and twist handle 2's perpendicular is connected. The front end of the inserted link 1 is provided with a shifting sheet 3, the rear section of the inserted link 1 is provided with a reducing section in a lathing mode, a return spring 4 is sleeved on the reducing section, and gaskets 5 and 6 are respectively sleeved on the front and rear end of the return spring 4 in the reducing section of the inserted link so as to shield the end part of the return spring 4. And the outer side of the gasket 6 at the rear end of the return spring 4 limits the return spring 4 and the check ring 6 by clamping the check ring 7 on the inserted link 1.
As shown in fig. 2 and 3, two electromagnets 9 are installed in a base 8 of the double-push electromagnet brake, and a reducing shoulder is provided in a base insertion hole of the base 8 to block a washer 5 at the front end of a return spring 4 when an insertion rod 1 is inserted into the base insertion hole. Thus, under the normal condition, the inserted link 1 cannot be completely inserted into the base jack under the action of the return spring 4, but is in a half-inserted state, and the shifting piece at the front end of the inserted link 1 exits from the gap between the two electromagnets 9. When the brake is required to be released, the inserted bar 1 is pushed to the bottom, and then the torsion bar 2 is pulled, so that the normal brake releasing action of the double-push electromagnet brake can be realized.
