Abstract
The invention provides a kind of brake type device for revolving and driving with brake structure, usually on common device for revolving and driving, arrange break, break is made up of push rod, brake slipper, brake valve etc.During braking, brake valve drives push rod to stretch out, and is advanced, brake slipper is engaged with pivoting support external toothing, thus reaches the object of braking by the slope driving brake slipper of push rod; When device for revolving and driving needs normally to work, push rod is return by brake valve, drives brake slipper to return simultaneously, brake slipper and pivoting support are separated, thus cancel braking.The present invention owing to adding break, thus can take emergency braking when emergency case to device for revolving and driving, to reach the object of protection device for revolving and driving or personnel.
Description
Technical field
The present invention relates to a kind of device for revolving and driving, refer to a kind of device for revolving and driving of band brake structure especially.
Background technique
Device for revolving and driving is the new machine parts grown up in recent decades, it is from for excavator and hoist, develop into for other machinery gradually, 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 axial force, radial force, tilting moment simultaneously, also have simple installation simultaneously, be easy to safeguard, save the features such as installing space to a greater extent.
Adopt device for revolving and driving as the solar photovoltaic assembly of rotary component, can adjust accurately the corner of main frame and the elevation angle position different according to the sun in a day, the moment makes solar panel be in best receiving angle.Under most occasion, device for revolving and driving does not make continuous rotary, but only does to come and go in several angle to rotate, and is equivalent to so-called " oscillation bearing ".
At present, general device for revolving and driving does not all install braking device, in particular cases just cannot complete emergency braking at some, device may be caused to damage or minimizing in working life, the personnel that even can cause injure.Therefore, a kind of device for revolving and driving of band brake structure is needed.
Summary of the invention
The object of this invention is to provide a kind of brake type device for revolving and driving with brake structure.
For realizing the object of the invention, this brake type device for revolving and driving, comprise pedestal 1, pivoting support 3, worm screw 2, described pedestal 1 is made up of axle housing 11 and seat ring 12 liang of parts, the shaft axis of axle housing 11 and the shaft axis of seat ring 12 orthogonal in 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 the ball 33 be embedded between inner ring 31 and external toothing 32, external toothing 32 is provided with some installation screws, inner ring 31 is fixed on the top of the seat ring 12 of pedestal 1, external toothing 32 engages with worm screw 2, it is characterized in that, the outside of described seat ring 12 is also at least provided with a break 6, described break 6 comprises Brake Block 65, Brake Block 65 is connected with seat ring 12, push rod 61 is provided with in Brake Block 65, brake slipper 62, commutation block 63, brake valve 64, described commutation block 63 is connected with seat ring 12 and is provided with mutually vertical and two passages be communicated with, brake slipper 62 one end is provided with the tooth that engages with external toothing 32 and is arranged in a passage of the block 63 that commutates, the front end of push rod 61 is inclined-plane and is arranged in another passage of commutation block and penetrates in brake slipper 62 corresponding hole, the other end of push rod 61 is connected with brake valve 64.
Further, described break 6 arranges two, and is symmetrical arranged outside seat ring 12.Two usual synchronous workings of break.
The present invention increases and is provided with brake structure in common device for revolving and driving, the working principle of brake structure is: during braking, and brake valve drives push rod to stretch out, and is advanced by the slope driving brake slipper of push rod, brake slipper is engaged with pivoting support external toothing, thus reaches the object of braking; When device for revolving and driving needs normally to work, push rod is return by brake valve, drives brake slipper to return simultaneously, brake slipper and pivoting support are separated, thus cancel braking.
The present invention can arrange a break, also can be symmetrical arranged two breaks.If only arrange a break, then, when braking operation, 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 operation, active force that pivoting support is subject to is symmetrical and cancel out each other, and therefore, solves a unbalanced problem of detent force well.Certainly, also can arrange multiple break, but when arranging multiple break, structure being too complicated, is good with two usually.
The present invention owing to adding break in common device for revolving and driving; thus emergency braking can be taked when emergency case to device for revolving and driving; device for revolving and driving is stopped immediately; reach the object of protection device for revolving and driving or personnel with this, so just can meet the Special use requirement of client.
The brake structural that the present invention sets up is simple, 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.
It should be noted that, under the prerequisite not changing principle of the present invention and design, can also make some changes or distortion to the present invention, this belongs to protection scope of the present invention equally.
