Abstract
The invention discloses an automatic braking electric gourd comprising a shell of the electric gourd, a coiling cylinder, a motor and a reducer, which is characterized in that: a smooth surface is arranged at one end of the coiling cylinder; a brake band is arranged on the smooth surface; one end of the brake band is fixed on an terminal of one side of the shell while the other end of the brake band is connected with a braking device comprising a support frame and an electric hydraulic impeller; power of the electric hydraulic impeller is first connected on an automatic control switch and then connected with a speed sensor; a suspender is fixed on one side of the shell by the support frame and a horizontal fulcrum is connected with the suspender and the other end of the horizontal fulcrum is articulated with a vertical lever; a top end of the vertical lever is connected with the brake band and the electric hydraulic impeller is arranged between the bottom of the vertical lever and the suspender. When the electric gourd is out of control and reversely rotates with high speed, the automatic control switch connects power circuit of the impeller after receiving an over-speed signal; then a catch bar of the impeller extends so that the brake band gradually and tightly holds the coiling cylinder so as to stop the rotation, thus avoiding occurrence of accidents.
Description
Technical field
The application relates to the hoisting crane electric block.
Background technology
Electric block on the hoisting crane tends to take place drum shaft through long-term use and twists off, mechanical breakdowns such as gearbox gear damage, in case machinery is malfunctioning, the drum shaft hypervelocity is reversed under the lifting state, and the weight of slinging can fall rapidly, causes the accident.
Summary of the invention
The application proposes a kind of electric block of autobrake for solving the safety problem of electric block when malfunctioning.
For reaching the purpose of autobrake, existing electric block is improved, improved technical scheme is: it comprises shell, barrel, motor and the retarder of existing electric block, it is characterized in that, one end of barrel is left a circle light face, a circle brake band is installed on the position of a circle light face, an end of brake band is fixed on a side head of electric block shell, the other end of brake band is connected on the brake equipment after walking around barrel light face, and the structure of brake equipment is:
Be made up of bracing frame and electro hydraulicthruster, the power supply of electro hydraulicthruster is connected on the automatic control switch, and automatic control switch is connected on the speed sensor again; Bracing frame is to fix a suspension rod in a side of electric block shell, connect a cross support arm on the suspension rod, the other end with cross support arm is point articulated one a perpendicular lever, and perpendicular lever top is connected with brake band, installs electro hydraulicthruster between the bottom of perpendicular lever and suspension rod.
Above-mentioned automatic control switch is made up of control circuit, its principle of work is, when electric block is out of control, rapidly reversing, the acceptor circuit of automatic control switch make the relay coil energising, relay contact closure after receiving overspeed signal, connect the electro hydraulicthruster power circuit, the catch bar of electro hydraulicthruster stretches out, and makes brake band hold barrel gradually tightly and stops operating, thereby avoid the generation of accident.
Description of drawings
Fig. 1 is the electric block scheme drawing of autobrake, and Fig. 2 is the enlarged drawing of Figure 1A-A cutaway view.
Among the figure: 1-electric block shell, the 2-barrel, the 3-brake band, the 4-retarder, the 5-bracing frame, the 6-electro hydraulicthruster, the 7-automatic control switch, the 8-speed sensor, the 9-motor, the 10-suspension rod, 11-erects lever, 12-cross support arm.
The specific embodiment
The electric block embodiment of autobrake is described according to Fig. 1 Fig. 2 below.
As shown in Figure 1, it comprises parts such as existing electric block shell 1, barrel 2, motor 9 and retarder 4, it is characterized in that, one end of barrel 2 is left the light face, one circle brake band 3 is installed on the position of a circle light face, one end of brake band 3 is fixed on a side head of electric block shell 1, and the other end of brake band 3 is connected on the brake equipment after walking around barrel 2 light faces.The structure of brake equipment as shown in Figure 2, it is made up of bracing frame 5 and electro hydraulicthruster 6, the power supply of electro hydraulicthruster 6 is connected on the automatic control switch 7, automatic control switch 7 is connected on the speed sensor 8 again; As can be seen from Figure 2, bracing frame 5 is to fix a suspension rod 10 in a side of electric block shell 1, connect a cross support arm 12 on the suspension rod 10, be point articulated one a perpendicular lever 11 with cross support arm 12, perpendicular lever 11 tops are connected with brake band 3, install electro hydraulicthruster 6 between the bottom of perpendicular lever 11 and suspension rod 10.
The YT1-182B series that above-mentioned electro hydraulicthruster can select for use Henan Jiaozuo City rivers drg factory to produce.
