Abstract

The utility model belongs to hoisting device field, which particularly is an electric block with safety brake, which is comprised by an electric motor, a speed reducer and a wound roll, the electric block is directly provided with a speed reducer, which is arranged on the wound roll and rotates through wound roll is driven by transmission shaft, Which is characterized in that: the other end of transmission shaft of wound roll is extended and provided with a safety shaft on a transmission and extend shaft, the safety shaft is featured with simple structure, reasonable design, safe and reliable application, guaranteeing the brake effect of electric block through dual master structure, and particularly when the brake device malfunction of a brake motor occurs, the safety brake can go on braking, thus the safety performance is increased while the electric block is being applied, and the incidence rate of industrial accident is reduced, and the life safety of worker is guaranteed.

Description

The electric block of band sure brake
Technical field
The utility model belongs to the weight-lifting equipment field, especially a kind of electric block with sure brake.
Background technology
Electric block becomes the more frequent weight-lifting equipment of use in the factory because of it has advantages such as make and maintenance is convenient, simple to operate, lift cargo is convenient and swift.In commercial production, the most volume of the goods of electric block handling is big, and weight is heavier, in order to guarantee to keep the safety in production and safeguard work personnel's personal safety, requires electric block to have higher safety.In order to address this problem, brake equipment is installed all on the electric block.The electrical motor that brake equipment directly is equipped with in the existing many uses of electric block is controlled electric block, because the brake equipment of electrical motor direct mount is because the long-time situation that can wearing and tearing occur even damage of using, and when this situation occurring, electric block just may produce can not normal brake application problem, and cause industrial accident, even entail dangers to workman's life security.Therefore only adopt the mode of once braking can not solve the problem of electric block braking well, good electric block is very important to develop a kind of safety performance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, reasonable in design, can realize the electric block of the band sure brake of two brakings.
The utility model is achieved through the following technical solutions:
The electric block of this band sure brake, comprise electrical motor, retarder and reel, electrical motor direct mount retarder, this retarder is installed on the reel and drives reel by transmission shaft and rotates, it is characterized in that: prolong in the other end prolongation of reel transmission shaft and in this transmission a sure brake is installed on the axle, this sure brake is packed on the base plate of reel ends by its adapter plate that installs.
And, be fixed with a cylindrical shell that can seal this sure brake on the adapter plate of described sure brake.
And, an axle sleeve plate also is installed between described adapter plate and the base plate, on transmission prolongation axle, an axle sleeve is installed, the axle sleeve plate is installed on this axle sleeve.
Advantage of the present utility model and good effect are:
1. the utility model adopts to connect the structure of a sure brake on the transmission shaft in reel and increased a brake equipment thus on the basis of existing electric block, makes electric block become secondary braking by once braking.This double brake mode can guarantee the braking effect of electric block effectively, has improved it and has used the safe reliability of operation.
2. this electric block with secondary braking structure, structure design is very reasonable, and is simple to operation quick.When manipulating, two brake equipments can be braked successively, and the mode that secondary braking mutually combines can effectively improve braking effect, reduce braking time; When the brake equipment in the electrical motor breaks down or during brake failure, can adopt the sure brake of being installed that electric block is braked, therefore can not take place to cause taking place the phenomenon of industrial accident because of the motor braking device is out of order, can better guarantee the braking effect of electric block, improved the safety performance of electric block, reduce the generation of industrial accident, guaranteed workman's life security.
3. the utility model is simple in structure, reasonable in design, safe and reliable, adopt the double brake mode to guarantee the braking effect of electric block effectively, when especially the brake equipment of electrical motor broke down, sure brake can be proceeded braking, had improved the safety performance when electric block uses, reduced the incidence of industrial accident, actv. has guaranteed workman's life security.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but is not limited to the concrete structure that present embodiment is narrated.
The electric block of this band sure brake comprises electrical motor 10, retarder 9 and reel 8, electrical motor direct mount retarder, and drive the retarder motion, this retarder is installed on the reel, and drives the reel rotation by transmission shaft.Innovative point of the present utility model is: the other end at the reel transmission shaft prolongs, and on this transmission prolongation axle 7, a sure brake 2 is installed, this transmission prolongs axle and links to each other with the joint element of sure brake, make electric block have the secondary braking structure, actv. has guaranteed the reliability of service of electric block.This sure brake is packed on the base plate 5 of reel ends by an adapter plate 3, and sure brake is packed on this adapter plate by bolt; Also be fixed with a cylindrical shell 1 that can seal sure brake on this adapter plate; Also by bolt an axle sleeve plate 4 is installed between this adapter plate and the base plate, on transmission prolongation axle an axle sleeve 6 is installed, the axle sleeve plate is installed on this axle sleeve.
On electric block, be equipped with one and have the electric apparatus control apparatus (not shown), be used for controlling the operation of electric block, on reel, also be wound with the steel rope (not shown) that its lower end has suspension hook.
Principle of work of the present utility model is:
Electric block needs glancing impact, by using electric apparatus control apparatus electrical motor and sure brake is braked successively, thereby electric block is quit work; If brake equipment in the glancing impact electrical motor breaks down or during brake failure, the sure brake that electric block is installed can work alone, and directly reel is braked by the transmission shaft in the reel, and reel is quit work.

Claims (3)

1. electric block with sure brake, comprise electrical motor, retarder and reel, electrical motor direct mount retarder, this retarder is installed on the reel and drives reel by transmission shaft and rotates, it is characterized in that: prolong in the other end prolongation of reel transmission shaft and in this transmission a sure brake is installed on the axle, this sure brake is packed on the base plate of reel ends by its adapter plate that installs.
2. the electric block of band sure brake according to claim 1 is characterized in that: be fixed with a cylindrical shell that can seal this sure brake on the adapter plate of described sure brake.
