Description
Technical field
The utility model is related to a kind of crane gear, and in particular to a kind of c-type structure double-brake electric hoist.
Background technology
Using more frequently crane gear when electric block is production, it is generally moved by motor driving reducer, subtracted
Fast device is connected with reel and drives drum rotation, and the suspension hook that the end of the steel wire rope wound on reel is installed slings goods, and
It is transported to appointed place.In actual industrial production, the most volume of goods of electric block handling is big, heavier-weight, in order to protect
Card safety in production and the personal safety for ensureing workman, it is desirable to which electric block has higher security, therefore on electric block all
Brake apparatus is installed.Existing electric block is carried out usually using the motor for being mounted directly brake apparatus to electric block
Braking, the brake apparatus installed by motor is direct to motor to be braked, and motor stops reel by decelerator again
Only work.The brake apparatus that motor is mounted directly occurs because long-time is using the phenomenon that abrasion occurs or even damages
During this phenomenon, electric block may produce the problem of being unable to normal brake application, and cause production accident, or even entail dangers to workman
Life security, therefore can not solve the problem of electric block is braked well only with the mode once braked.
The content of the invention
To solve the above problems, the utility model provides a kind of c-type structure double-brake electric hoist, simple in construction, braking
Effect is good.
The utility model uses following technical scheme：A kind of c-type structure double-brake electric hoist, including motor, first
Brake, reductor, roller and second brake, set the first brake, motor, the first system between motor and reductor
Dynamic device, reductor and roller constitute c-type structure, and second brake is arranged on roller, the second brake include rotating disk and
Backing pin, rotating disk is fixed on roller, is uniformly fixed with projection on rotating disk excircle, backing pin is fixed on connecting rod, and connecting rod passes through solid
The ring flange of rationed marketing and roller is hinged, and the side of connecting rod is provided with micromachine, and micromachine is fixed on ring flange, micro electric
The output shaft of machine is connected by pull rope with connecting rod, and the opposite side of connecting rod is connected with back-moving spring.
Velocity sensor is provided with the ring flange.
The rotating disk is bolted by two semicircular rings.
The beneficial effects of the utility model are：The utility model uses the connection second on the roller of brake retarder to brake
Device, makes electric block become secondary braking by once braking, and this double brake structure is effectively guaranteed electric block
Braking effect, improves security performance when it is used；It is simple in construction, reasonable in design, safe and reliable, using double brake
Structure is effectively guaranteed the braking effect of electric block, and when especially the first brake breaks down, second brake can be only
It is vertical to be braked, security performance when electric block is used is improved, the incidence of production accident is reduced, is effectively guaranteed
The life security of workman.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A direction views in Fig. 1.
Fig. 3 is the structural representation of rotating disk.
Embodiment
As shown in Figure 1 and Figure 2, a kind of c-type structure double-brake electric hoist, including motor 9, the first brake 8, deceleration
Machine 7, roller 6 and second brake, set the first brake 8, motor 9, the first brake between motor 9 and reductor 7
8th, reductor 7 constitutes c-type structure with roller 6, and second brake is arranged on roller 6, and the second brake includes the He of rotating disk 4
Backing pin 2, rotating disk 4 is fixed on roller 6, is uniformly fixed with projection 1 on the excircle of rotating disk 4, backing pin 2 is fixed on connecting rod 3, connecting rod
3 are hinged by the ring flange 5 of steady pin 13 and roller 6, and the side of connecting rod 3 is provided with micromachine 11, and micromachine 11 is fixed
On ring flange 5, the output shaft of micromachine 11 is connected by pull rope 12 with connecting rod 3, and the opposite side of connecting rod 3 is connected with reset
Velocity sensor is provided with spring 10, ring flange 5, velocity sensor is electrically connected with micromachine 11.
Rotating disk 4 is bolted by two semicircular rings, it is not necessary to dismantle other parts on electric block, you can completed
The installation and dismounting of rotating disk, it is simple and convenient；It is reasonable in design, it is easy to assembly, in maintenance process, installation time is substantially reduced,
Bolt need only be pulled down during replacing, two parts semicircular ring is pulled open with regard to that can replace with new rotating disk.
During normal work, rotating disk is rotated with reel, when lifted weight thing acceleration decline is uncontrollable, velocity pick-up
Device detects signal, is transmitted to micromachine, and micromachine is opened, rotated by pull rope drivening rod, and then make backing pin clamping
Rotating disk, rotating disk stops operating, and reel also stops operating immediately.The apparatus structure is simple, is easily installed and dismantles, cost is low；Increase
Provided with second brake, when motor braking breaks down, the braking effect of good safety can be still realized, safety is improved
Property.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as this reality
With new protection domain.
