Abstract
The utility model relates to a brake which is used on a hoister, which comprises a brake band, a connecting plate, a roller, a guide pillar, a spring, an adjustment cap and a connecting shaft, wherein the guide pillar is fixedly arranged on the brake band, the connecting plate is sleeved on the guide pillar, the spring and the adjustment cap are respectively arranged on the guide pillar, and the roller is supported through the connecting shaft to contact with a rope roll of the hoister. Because the spring and the roller are jointed, the brake band and the rope roll are capable of being separated when the brake band is in a state of non-braking. Because the roller is arranged, the braking resistance of the brake band and the rope roll is capable of being reduced in the state of non-braking, thereby the operation is more relaxed. Because the structure is simple and reasonable, the brake has a large practicality and popularization value.
Description
Technical field
The utility model relates to a kind of parts of winch, the winch drg that is used to brake on specifically a kind of winch.
Background technology
Relevant by retrieval patent documentation does not retrieve the winch drg identical with the utility model structure at present as yet.The winch kind of using in the existing engineering is more, differ from one another, large-scale winch is generally taked to brake to bring aspect stop mechanism rope roll is braked, because brake wheel and brake collar diameter are bigger, so brake collar is usually still attached to the rope roll surface when unclamping, cause unnecessary resistance, thus be necessary existing drg is improved, to improve the performance of product.
Summary of the invention
The purpose of this utility model is will provide a kind of and have good braking effect, unclamp winch drg easily.
Technical characterictic of the present utility model is: the winch drg that is designed to comprise brake collar, connecting panel, roller, guide pillar, spring, adjusting cap, adapter shaft on the basis of considering good braking effect, on brake collar, be fixed with guide pillar, on guide pillar, be set with connecting panel; On guide pillar, be respectively equipped with spring, regulate cap; Roller supports by adapter shaft, contacts with the rope roll of winch.
Described brake collar is provided with the groove that roller is passed through.
Described connecting panel is provided with the open slot that matches with adapter shaft.
During use, brake collar is enclosed on the external diameter of rope roll, and roller contacts with rope roll under the elastic force of spring, and brake collar and rope roll keep separated position under the effect of roller simultaneously; When the needs glancing impact, the pulling brake equipment, brake collar overcomes the elastic force of spring and embraces rope roll, thus the starting braking effect; When needs elimination glancing impact, take-off the brake power, under the effect of spring force, connecting panel promotes roller and contacts with rope roll, thereby brake collar and rope roll are separated, and has eliminated braking.
The utility model has the advantages that: owing to adopt spring to engage with roller, thus make brake collar that brake collar and rope roll are separated; Owing to be provided with roller, thereby under non-braking mode, can reduce the brake holding resistance of brake collar and rope roll, make running lighter; Since simple and reasonable for structure, so very big practical and popularizing value is arranged.
Description of drawings
Below with reference to accompanying drawing the utility model is further described:
Accompanying drawing 1 is the structural representation of the utility model winch with drg;
Accompanying drawing 2 be along accompanying drawing 1A to the local structure scheme drawing.
The specific embodiment
With reference to accompanying drawing 1, accompanying drawing 2, winch of the present utility model is made up of brake collar 1, connecting panel 2, roller 3, guide pillar 4, spring 5, adjusting cap 6, adapter shaft 7 with drg, is fixed with guide pillar 4 on brake collar 1, is set with connecting panel 2 on guide pillar 4; On guide pillar 4, be respectively equipped with spring 5, regulate cap 6; Roller 3 contacts with the rope roll of winch by adapter shaft 7 supportings.Brake collar 1 is provided with the groove 11 that roller 3 is passed through.Connecting panel 2 is provided with the open slot 71 that matches with adapter shaft 7.
