Abstract
A broach holdback of an improved control device comprising a ratchet-and-pawl arrangement, wherein, the ratchet is fixedly connected with the barrel arbor or the broach side board and ganged with the broach, the broach holdback is characterized in that the broach holdback provides another ratchet control device which is equipped with a rubbing sleeve fixing on the barrel arbor, the rubbing sleeve verge detachable fitting connects two band brake arcs or the half-round friction block wherein the ends are connecteded with bolt fastening units, a spring which adjustes the friction force between the friction block and the rubbing sleeve is package packing in the bolt fastening units, one end of the friction block and the pawl is detachably connected by a push-pull connecting bar, when the barrel arbor is in working order, the friction block relative the rubbing sleeve and the barrel arbor can be rotated freely, the frictional couple between the friction block and the rubbing sleeve can push the pawl by the connecting bar, the pawl opened automatically and contacted with ratchet is released, thereby, the ratchet can run well without noise.
Description
Technical field
The utility model relates to a kind of improvement technology that is used for the Hoisting Machinery stopper, and particularly a kind of have a reel stopper that improves control gear, is particularly useful for adopting on the winch of break open in usual using.
Background technique
The winch that is used for the goods lifting is at present realized the goods landing by the reel Wound steel rope, cause security incident in order to prevent driving unit fault, just need on lifting drum, install stopper additional, specifically be on the spool shaft of winch or reel side plate, to add ratchet and the stopper that ratchet is formed is housed on frame, when the reel counter-rotating appears in winch because of breaking down, can limit ratchet by ratchet rotates to guarantee to realize safety control, but also exist: ratchet can knock ratchet repeatedly when normally hoisting, annoying noise not only occurs, and unnecessary equipment attrition can occur.Above-mentioned phenomenon causes many users to remove ratchet with being regardless of the consequences, badly influences the safe handling of equipment.
The model utility content
The purpose of this utility model is to overcome above-mentioned defective, thereby design a kind of reel stopper with improvement type control gear, make when the reel normal rotation, ratchet can be opened automatically, reel and ratchet are run well to have no abnormal sound, when transmission system is out of order reel appearance counter-rotating, can prevent the reel counter-rotating again, guarantee that equipment is safe in utilization.
The utility model is realized with following technological scheme: this stopper still comprises ratchet and pawl arrangement, wherein ratchet is fixedly connected on spool shaft or the reel side plate and with reel and links, also has the ratchet control mechanism that (passing through control arm) and ratchet flexibly connect in addition, when the needs reel reverses, can ratchet be withdrawed from not influence the counter-rotating of reel by this control mechanism, it is characterized in that in this reel stopper, also being equipped with the control gear that another is used to control ratchet, this control gear has fixedly sleeved on a spool shaft friction sleeve, be connected to two arcs or the semicircle brake pad of band-type brake shape in the outer of friction sleeve activity engage sleeves again, two at brake pad is connected by bolt connection piece respectively, be set with the spring that to adjust frictional force size between brake pad and the friction sleeve on the bolt connection piece, between the wherein termination of brake pad and ratchet, be connected with a push-and-pull connecting rod, when spool shaft begins proper functioning, brake pad can freely rotate mutually with respect to friction sleeve and spool shaft, in proper functioning, can make the friction torque between brake pad and the friction sleeve push ratchet open again by connecting rod, promptly allow ratchet open the engagement that breaks away from ratchet automatically, ratchet is run well have no abnormal sound.Be out of order as if transmission system in the work, when reel reverses under the effect of weight, friction torque between brake pad and the friction sleeve can spur ratchet round about and ratchet is pressed on the ratchet automatically and be engaged with by the push-and-pull connecting rod, guarantees weight do not fall (landing).
The utility model in the specific implementation, also can save friction sleeve, and with two arcs or the direct movable set of semicircle brake pad on spool shaft, and the position that relies on friction torque between brake pad and the spool shaft to control ratchet runs well ratchet to have no abnormal sound (accompanying drawing is slightly).
In the specific implementation, also can be designed to described two arcs or semicircle brake pad movable set with the spool shaft coaxial inner conductor and be fixed on the round shell type solid of rotation on the reel, and rely on friction torque between brake pad and the solid of rotation to control the position of ratchet, ratchet is run well have no abnormal sound (accompanying drawing is slightly).
Compared with the prior art, the stopper that uses the utility model to be equipped with another auxiliary ratchet control gear has the following advantages, and when the reel normal rotation, ratchet is opened automatically, and ratchet is run well, and has no abnormal sound.If transmission system is out of order, ratchet then can be pressed on the ratchet automatically when reel reversed under the effect of weight, guaranteed that weight does not glide in the work.When the needs reel reverses, can ratchet be withdrawed from by the control mechanism of former prior art, do not influence the reel counter-rotating.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model
Embodiment
In the embodiment of accompanying drawing 1, the concrete component of the utility model reel stopper structure comprise: 1～bolt, 2～spring, 3～brake pad, 4～friction sleeve, 5～spool shaft, 6～reel side plate, 7～push-and-pull connecting rod, 8～ratchet, 9～frame, the control mechanism of the former prior art on 10～ratchet, 11～ratchet.Wherein ratchet is contained on the side plate that is positioned at reel, ratchet is contained in the relevant position of frame, friction sleeve is fixedlyed connected with spool shaft, two brake pads are connected by bolt, and by adjusting the pressure size of spring, make the friction torque of brake pad and friction sleeve be enough to make ratchet to be opened, ratchet is run well and have no abnormal sound.If transmission system is out of order, ratchet was pressed on the ratchet automatically when reel reversed under the effect of weight, guaranteed that weight does not glide in the work.When the needs reel reverses, can ratchet be withdrawed from by existing ratchet control mechanism, do not influence the reel counter-rotating.
Claims (3)
1, a kind of reel stopper with improvement type control gear, it comprises ratchet and pawl arrangement, wherein ratchet is fixedly connected on spool shaft or the reel side plate and with reel and links, has a ratchet control mechanism that flexibly connects with ratchet, it is characterized in that in this reel stopper, being equipped with the control gear that another is used to control ratchet, this control gear has in spool shaft (5) goes up a fixedly sleeved friction sleeve (4), be connected to two arcs or the semicircle brake pad (3) of band-type brake shape in the outer of friction sleeve activity engage sleeves, two at brake pad is connected by bolt connection piece respectively, be set with the spring (2) that to adjust frictional force size between brake pad and the friction sleeve on the bolt connection piece, between the wherein termination of brake pad and ratchet (8), be connected with a push-and-pull with connecting rod (7), when spool shaft begins proper functioning, brake pad can freely rotate mutually with respect to friction sleeve and spool shaft, in proper functioning, can make the friction torque between brake pad and the friction sleeve push ratchet open by connecting rod again, the engagement that promptly allows ratchet open disengaging and ratchet automatically runs well ratchet and has no abnormal sound.
