Abstract
The invention discloses a braking device which comprises a braking belt (1) and a rotational driving mechanism (2), the braking belt (1) is a circular arc, one end part (1a) of the circular arc is provided with a hinged point, and the rotational driving mechanism (2) drives the braking belt (1) to rotate freely around the hinged point (2a) at the end part; and the braking device also comprises a pair of braking belt (1) stop devices, wherein the stop devices comprise a roller wheel (4) and a supporting platform (5), the roller wheel (4) and the supporting platform (5) adopt a pin shaft to connect, and the roller wheel (4) can rotate around the central shaft line. The braking device provided by the invention has the advantages that the structure is simple, and the locking of the clamping belt can be avoided.
Description
Technical field
The invention belongs to the braking technology field, relate in particular to a kind of braking device that adopts clamping strap to brake.
Background technique
In present braking technology field, have and a kind ofly use braking to bring wheel hub or other rotating disk cylinder are held tightly the device of braking.Because clamping strap is the parts with rotary freedom, and the degree of holding tightly that a limit stoper is controlled band need to be set.Traditional to clamping strap limit structure since between the arc plate of limit position part and clamping strap for face contacts, although can play position-limiting action, simultaneously can stuck clamping strap, thus seriously hindered the action of returning of clamping strap.
Summary of the invention
Purpose of the present invention is the shortcoming that overcomes prior art, provide a kind of can either be to the spacing braking device that stuck clamping strap can not occur again of clamping strap.
For solving the problems of the technologies described above, concrete technological scheme of the present invention is as follows:
A kind of clamping strap comprises clamping strap and rotary drive mechanism, and described clamping strap is circular arc, and its circular arc one end is set to articulating point, and described clamping strap can rotate freely around the end articulating point;
Described rotary drive mechanism comprises a rotation hand wheel and the rotary screw that is connected with handwheel, and described rotary screw is divided into head threads section and polished rod section, supports described rotary screw at rotary screw polished rod Duan Youyi axle sleeve; Described axle sleeve is by the dunnage fixed support;
At described clamping strap one otic placode is set, is connected with the rotary screw thread section, make and form the screw thread transmission between drive unit and the clamping strap;
Described braking device also comprises a pair of clamping strap limit stoper, and described limit stoper comprises a roller and supporting frame, adopts bearing pin to connect between described roller and the supporting frame, and roller is around self central axis rotation.
The invention has the advantages that: realized well the restriction to the clamping strap position, avoided again the generation of braking device stuck phenomenon simultaneously, thereby made the normally work of safety of braking device.
Description of drawings
Fig. 1 is lamps structure schematic representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the brake member of braking device of the present invention is clamping strap 1, described clamping strap 1 is circular arc, one end points 1a and other parts of circular arc are hinged, circular arc clamping strap 1 can be realized freely rotating around this articulating point 1a, the present invention comprises that also one realizes the drive unit 2 of braking circular arc band rotation, described drive unit 2 comprises rotation hand wheel 2a and connected rotary screw 2b, rotary screw 2b comprises thread head 2b1 and polished rod part 2b2, and described thread head 2b1 and the otic placode 1b that is arranged on the clamping strap realize the screw thread transmission.Drive unit 2 also comprises the axle sleeve 2c of supporting rotating shaft simultaneously, and axle sleeve 2c is by dunnage 2d fixed support.A pair of clamping strap 1 also is set outside clamping strap 1 carries out spacing device, this device comprises a limited roller 4 and connected supporting frame 5, and the two connects by bearing pin, and roller 4 can rotate freely around its central axis.
Specific works flow process of the present invention is as follows: when rotary component being held tightly braking, only need rotatable handle 2a to get final product, be centered by the articulating point 1a of its end through screw drive structure clamping strap 1 and be rotated counterclockwise, clamping strap 1 fits in rotary component gradually, and realizes the braking to rotary component; But a pair of clamping strap 1 need to be set carry out spacing device with the hold degree of control clamping strap to rotary component, that face contacts between the limit position part of traditional limit stoper and the clamping strap 1, might stuck clamping strap 1, remove braking to rotary component thereby make can not reverse with 1.The limit position part of limit stoper of the present invention is a roller 4, in the cancellation braking process since between roller 4 and the braking support roller sheet 1 for line contacts, while roller 1 can rotate freely, and has effectively avoided stuck phenomenon.
The present invention has namely realized spacing to clamping strap, avoids again the phenomenon of stuck clamping strap simultaneously.
Claims (1)
1. a braking device comprises clamping strap (1) and rotary drive mechanism (2), and described clamping strap (1) is circular arc, and its circular arc one end (1a) is set to articulating point, and described clamping strap (1) can rotate freely around end articulating point (1a); Described rotary drive mechanism (2) comprises a rotation hand wheel (2a) and the rotary screw that is connected with handwheel (2b), described rotary screw (2b) is divided into head threads section (2b1) and polished rod section (2b2), has an axle sleeve (2c) to support described rotary screw (2b) in rotary screw polished rod section (2b2); Described axle sleeve (2c) is by dunnage (2d) fixed support; At described clamping strap (1) otic placode (1b) is set, (2b2) is connected with the rotary screw thread section, makes and forms the screw thread transmission between drive unit (2) and the clamping strap (1); It is characterized in that: described braking device also comprises a pair of clamping strap (1) limit stoper, described limit stoper comprises a roller (3) and supporting frame (4), adopt bearing pin to connect between described roller (3) and the supporting frame (4), roller (3) is around self central axis rotation.
