Description
Technical field
The utility model relates to a kind of workover rig winch brake gear.
Background technology
Workover rig winch brake gear generally has band brake and disk type brake two kinds of forms.Band brake is by rotating crank throw, makes brake strap hold brake hubs tightly to complete drag.Disk type brake completes drag by HYDRAULIC CONTROL SYSTEM braking clamp clamping brake disc.The radical function of brake checks or stop slow cylinder to control the below speed of hook block.A lot of drilling team is more ready to use band brake, because band brake is connecting rod mechanism, makes operator more have the feel of index drum speed, very easily operates.And disk type brake cost is higher, often safeguard, friction material requires also high.General band brake regulates distance between brake shoes and drum brake hub by Limit screw, and this regulative mode makes the distance between brake hubs and brake shoes uneven.In brake process, will more easily wear and tear in some position, and maintenance times will increase.Add the working strength of workman, reduce work efficiency.
Number of patent application 200620093465.7, disclose a kind of cylinder braking device, brake lever assembly, connecting lever, pull bar, crank throw, brake axle, link arm is utilized to form lever, tension brake endless belt, realize the braking to cylinder, the whole braking procedure of the method is realized by the elastic force of brake endless belt, and brake ring belt wear amount is large, need frequent replacing brake endless belt, affect its service life.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of workover rig winch brake gear, and the gap between adjustable brake shoes and drum brake hub, guarantees braking effect, extends the service life of brake gear.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of workover rig winch brake gear, comprises Compress Spring, support, drag hook, brake hubs, brake shoes, brake strap, crank throw, link arm, connection otic placode, and crank throw is hinged with link arm, and the link arm other end is with to be connected otic placode hinged, and connection otic placode is connected with brake lever; Brake strap side is provided with drag hook, and opposite side is provided with brake shoes, and brake hubs outside is provided with brake shoes, and the drag hook other end is provided with Compress Spring, and the Compress Spring other end is resisted against on support, and drag hook is arranged on support.
Described brake shoes and brake strap are bolted.
Described drag hook both sides are provided with caging bolt.
Described both ends of the spring is provided with rounded stops, and block is provided with boss, and boss external diameter and spring inside diameter match.
Described brake strap is connected with drag hook hook.
Compared with prior art, the beneficial effects of the utility model are:
Braking effect is good, improves the service life of brake gear.The friction of brake shoes and brake hubs is utilized to realize the object of braking, crank throw, link arm, the interlock of connection otic placode, lever principle is utilized to realize the band-type brake of brake shoes, Compress Spring and drag hook realize the adjustment to gap between brake shoes and brake hubs, also play the compensation to brake shoes wearing and tearing, do not affect braking effect; By caging bolt, prevent drag hook by the excessive clearance between drum brake hub and brake shoes, cause drag to lose efficacy.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of workover rig winch brake gear, comprise Compress Spring 1, support 2, drag hook 3, brake hubs 5, brake shoes 6, brake strap 7, crank throw 8, link arm 9, connect otic placode 10, crank throw 8 is hinged with link arm 9, link arm 9 other end, with to be connected otic placode 10 hinged, connect otic placode 10 and is connected with brake lever; Brake strap 7 side is provided with drag hook 3, and opposite side is provided with brake shoes 6, and brake hubs 5 outside is provided with brake shoes 6, and drag hook 3 other end is provided with Compress Spring 1, and Compress Spring 1 other end is resisted against on support 2, and drag hook 3 is arranged on support 2.
Wherein, brake shoes 6 and brake strap 7 are bolted.Drag hook 3 both sides are provided with caging bolt 4.Both ends of the spring is provided with rounded stops, and block is provided with boss, and boss external diameter and spring inside diameter match.Brake strap 7 is connected with drag hook 3 hook.
During brake, brake lever drives and connects otic placode 10, and connection otic placode 10 successively power transmission to link arm 9, crank throw 8, reduces the direct of brake shoes 6, friction brake hub 5, realizes braking.
Be provided with multiple Compress Spring 1 and drag hook 3 around brake shoes 6, drag hook 3 directly end is provided with screw thread, for regulating the degree of tightness power of drag hook 3.Thus realize regulating the gap between brake shoes 6 and drum brake hub 5 to be 3 ~ 5mm.
Realize brake strap 7 by rotation crank throw 8 and hold brake hubs 5 tightly.By installing Compress Spring 1 and drag hook 3 on support 2, widen the distance of drum brake hub 5 and brake shoes 6.Again by the caging bolt 4 that drag hook 3 both sides are provided with, prevent drag hook 3 by the excessive clearance between drum brake hub 5 and brake shoes 6, cause drag to lose efficacy.
The adjustment of drag hook 3 has come by bolt compresses spring 1, and space when requisite space is less than stretching when Compress Spring 1 compresses, draw direction is more easy to control.Compress Spring 1 two ends are provided with rounded stops, and block is provided with boss, and boss external diameter is identical with Compress Spring 1 internal diameter, increase spring stability.Caging bolt 4 is symmetricly set on drag hook 3 both sides, prevents brake shoes 6 unbalance stress from causing brake failure or part brake shoes 6 undue wear.
