Description
Technical Field
The utility model relates to a motor technology.
Background
Most of the past elevators are elevators with machine rooms, in recent years, the elevators without the machine rooms are developed very rapidly along with the requirements of space saving and energy saving of buildings, and along with the further popularization and application of the elevators without the machine rooms, the requirements of the elevators without the machine rooms in the market are increased day by day. The block brake has simple structure and low cost, is generally applied to elevator traction machines, and is particularly used in passenger elevators and a considerable number of goods elevators. In most of elevators without machine rooms, a guy cable is adopted to realize remote brake release, as shown in fig. 3 and 4, when an elevator is in power failure or a brake is in failure, in order to open the brake to rescue, the guy cable 5 is connected with brake release handles 1a of brakes 1 on two sides of a main machine, and then the guy cable 5a is led out from one side of the brake to a remote brake release wrench 5b, so that the brake release handles are opened in a remote control mode. However, in some elevator without machine room with narrow hoistway, due to space limitation, the side of the brake releasing handle of the main machine brake is basically next to the hoistway, guide rail or door machine, and in this case the traction cable cannot be led out from the brake side according to the scheme of fig. 2.
Disclosure of Invention
The invention aims to provide a block brake remote brake release device which can lead out and arrange a guy cable even if a well is narrow, realizes remote brake release and has simple structure, labor saving and safe reliability.
The utility model discloses a realize like this: the brake device comprises a brake and a brake releasing device which are arranged on a base of a host and are provided with brake releasing rods, and a remote brake releasing wrench, and is characterized in that the brake releasing device comprises a fixing frame arranged on the base, a left swinging connecting rod and a right swinging connecting rod which are symmetrically swung on the fixing frame, cable fixing shafts, brake releasing rod cables and transmission cables, the two cable fixing shafts are respectively and rotatably connected to the middle part of the left swinging connecting rod and the middle part of the right swinging connecting rod, the two brake releasing rod cables are respectively fixed between the brake releasing rods of the left brake and the cable fixing shafts at the middle part of the left swinging connecting rod and between the brake releasing rods of the right brake and the cable fixing shafts at the middle part of the right swinging connecting rod, two transmission power output ends of the transmission cables are respectively connected to the movable end part of the left swinging connecting rod and the movable end part of the right.
When the brake is released, the force of the remote brake releasing wrench is transmitted to the movable end part of the left swing connecting rod and the movable end part of the right swing connecting rod through the transmission inhaul cable, so that the movable end parts and the movable end parts of the right swing connecting rod swing relatively close to each other, the brake releasing rod inhaul cable connected to the middle part is driven, the brake releasing rod moves, and the brake is released. The adoption is including setting up the mount on the base, the left swing connecting rod and the right swing connecting rod of symmetry swing setting on the mount, the cable fixed axle, the release brake lever cable, the transmission cable adopts the release brake device of cable fixed axle, the release brake lever that the stopper was kept away from to two transmission power take off ends that make the transmission cable, keep away from the well promptly, guide rail or door machine, make the transmission cable carry out smoothly bending with gentle radian, and smoothly drive by long-range release spanner, and, because the transmission of left swing connecting rod and right swing connecting rod, be the transmission of lever, the power of having reduced the release brake, make the release brake easier and light. The middle part of the left swing connecting rod and the swing of the right swing connecting rod can be adapted by adopting the rotating inhaul cable fixing shaft, so that the connection point of the inhaul cable of the brake release rod is always right opposite to the connection point of the inhaul cable of the brake release rod.
Here, left side swing connecting rod and right side swing connecting rod all are the form of buckling, and the inflexion of left side swing connecting rod is relative with the inflexion of right side swing connecting rod, like this, just at the during operation, can avoid the encoder of host computer tip to make things convenient for the assembly maintenance encoder and do not influence the work of encoder.
Compared with the prior art, the utility model, even have that the well is narrower can both derive and arrange the cable, realize long-range floodgate that loosens, simple structure, laborsaving, fail safe nature's advantage.

Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings and examples:
as shown in fig. 1 and 2, the utility model discloses a stopper 3 and the brake release device b that have brake release lever 2 that set up on base 1 of host computer a, long-range brake release spanner 4, its special character lies in brake release device b including setting up the mount 5 on base 1, the symmetry swing sets up left swing connecting rod 6 and right swing connecting rod 7 on mount 5, cable fixed axle 8, brake release lever cable 9, transmission cable 10 (if adopt the cable of similar brake guy wire structure), two cable fixed axles 8 rotate respectively and connect at left swing connecting rod 6 middle part and right swing connecting rod 7 middle part, two brake release lever cables 9 are fixed respectively between the cable fixed axle 8 at the middle part of brake release lever 2 and left swing connecting rod 6 of left brake 3 and between the cable fixed axle 8 at the middle part of brake release lever 2 and right swing connecting rod 7 of right brake 3, two transmission power take off end 10a of transmission cable 10 connect respectively at the movable end of left swing connecting rod 6 and the activity of right swing connecting rod 7 The movable end part and the transmission power output end 10b of the transmission inhaul cable 10 are connected to the remote brake-releasing wrench 4.
The left swing connecting rod 6 and the right swing connecting rod 7 are both bent, and the inner bend 6a of the left swing connecting rod 6 is opposite to the inner bend 7a of the right swing connecting rod 7.
