Abstract
The utility model provides a braking type slewing drive device with a braking structure. Normally, a brake is arranged on a normal slewing drive device, and the brake is composed of a push rod, a braking block, a braking valve and the like. When braking is carried out, the braking valve drives the push rod to extend out to push the braking block to move forward through an inclined plane of the push rod, the braking block and the outer gear ring of a slewing bearing are made to be meshed with each other, and therefore the purpose of braking is achieved. When the slewing drive device needs to work normally, the braking valve sends back the push rod to drive the braking block to be sent back simultaneously, the braking block and the slewing bearing are made to be separated, and therefore the braking is cancelled. The brake is added to the braking type slewing drive device, therefore, emergency braking can be carried out on the slewing drive device when an emergency situation occurs, and the purpose of protecting the slewing drive device or personnel is achieved.
Description
Technical field
The utility model relates to a kind of device for revolving and driving, refers to especially a kind of device for revolving and driving of band brake structure.
Background technique
Device for revolving and driving is the new machine parts that grow up in recent decades, it is from being used for excavator and hoist, develop into gradually for other machinery, device for revolving and driving is widely used in Hoisting Machinery (truck crane, tower crane etc.), engineering machinery (excavator, loader etc.), Transport Machinery, material processing machine, metallurgical machinery, food processing machinery, and military equipment (tank, antiaircraft gun, radar, rocket launching pad etc.), medical machinery, research equipment, engineering machinery and the new energy fields such as sun-following solar generating and wind-power generating system.The core component of device for revolving and driving adopts pivoting support, therefore can bear simultaneously axial force, radial force, tilting moment, also has simultaneously simple installation, is easy to safeguard, saves to a greater extent the characteristics such as installing space.
Adopt device for revolving and driving as the solar photovoltaic assembly of rotary component, can come corner and the elevation angle of main frame are adjusted accurately according to the different position of the sun in a day, make solar panel be in best receiving angle constantly.Under most occasions, device for revolving and driving is not made continuous rotary, but only does to come and go rotation in several angle, is equivalent to so-called " oscillation bearing ".
At present, on the general device for revolving and driving braking device is not installed all, in particular cases just can't be finished emergency braking at some, may cause device to damage or the minimizing in working life, even the personnel that can cause injure.Therefore, the device for revolving and driving that needs a kind of band brake structure.
The model utility content
The purpose of this utility model provides a kind of brake type device for revolving and driving with brake structure.
For realizing the utility model purpose, this brake type device for revolving and driving, comprise pedestal 1, pivoting support 3, worm screw 2, described pedestal 1 is made of axle housing 11 and 12 liang of parts of seat ring, the shaft axis of the shaft axis of axle housing 11 and seat ring 12 is orthogonal in the spatial position, described worm screw 2 is installed in the axle housing 11 of pedestal 1, described pivoting support 3 comprises inner ring 31, external toothing 32 and be embedded at inner ring 31 and external toothing 32 between ball 33, be provided with some installation screws on the external toothing 32, inner ring 31 is fixed on the top of the seat ring 12 of pedestal 1, external toothing 32 and worm screw 2 engagements, it is characterized in that, the outside of described seat ring 12 also is provided with a break 6 at least, described break 6 comprises Brake Block 65, Brake Block 65 is connected with seat ring 12, be provided with push rod 61 in the Brake Block 65, brake slipper 62, commutation piece 63, brake valve 64, described commutation piece 63 is connected and is provided with two passages of mutually vertical and connection with seat ring 12, brake slipper 62 1 ends are provided with in the tooth that meshes with external toothing 32 and a passage that is installed in commutation piece 63, the front end of push rod 61 is in inclined-plane and another passage that is installed in the commutation piece and penetrates in the brake slipper 62 corresponding hole, and the other end of push rod 61 is connected with brake valve 64.
Further, described break 6 arranges two, and is symmetrical arranged in seat ring 12 outsides.Two common synchronous workings of break.
The utility model increases in common device for revolving and driving and is provided with brake structure, the working principle of brake structure is: during braking, brake valve drives push rod and stretches out, and the slope driving brake slipper by push rod advances, make the engagement of brake slipper and pivoting support external toothing, thereby reach the purpose of braking; When device for revolving and driving need to work, brake valve was return push rod, drove brake slipper and return simultaneously, and brake slipper and pivoting support are separated, thus the cancellation braking.
The utility model can arrange a break, also can be symmetrical arranged two breaks.If a break only is set, then when braking work, pivoting support is subject to asymmetric active force, easily accelerates the damage of pivoting support and even whole device for revolving and driving.When being symmetrical arranged two breaks, braking work, active force that pivoting support is subject to is symmetrical and cancel out each other, and therefore, has solved well a unbalanced problem of break active force.Certainly, also a plurality of breaks can be set, but when a plurality of break was set, structure was too complicated, usually take two as good.
The utility model is owing to having increased break in common device for revolving and driving; thereby can when emergency case, take emergency braking to device for revolving and driving; device for revolving and driving is stopped immediately; with this purpose that reaches protection device for revolving and driving or personnel, so just can satisfy client's Special use requirement.
The brake structural that the utility model is set up is simple, and reliable performance for common device for revolving and driving provides reliable braking function, can be widely used in the industries such as engineering machinery, building machinery, photovoltaic and use.
Need to prove, under the prerequisite that does not change principle of the present utility model and design, can also make some changes or distortion to the utility model, this belongs to protection domain of the present utility model equally.
