Abstract
The invention discloses a brake of a core drill. The brake comprises a shell, wherein a brake strap is arranged in the shell; two opposite brake blocks are connected onto the annular wall of the brake strap; a second bolt is arranged on the two brake blocks in a penetrating manner; one end of the second bolt is in rotation connection with a cam; the upper end part of the second bolt is provided with a pad and a copper pad; the lower end part of the second bolt is provided with a hex nut and a hex eccentric nut; a spring sleeves the second bolt between the two brake blocks; one side of the cam is provided with sawteeth; the sawteeth are mutually meshed with a pawl fixedly arranged on the shell; the cam is provided with a handle; when the handle is rotated to approach the shell, a support pad is arranged on a corresponding position of the shell. According to the brake disclosed by the invention, the two brake blocks are extruded through the action of the cam on the second bolt; further the brake belt is subjected to compressure brake; and the effects of rapid operation and good braking effect are realized.
Description
Technical field
The invention belongs to machinery manufacturing technology field, relate to a kind of rock-core borer, specifically a kind of break for rock-core borer.
Background technique
Rock-core borer is the one of Core Drilling Machine, and it is mainly used in generaI investigation and the exploration of metal and non-metal solid mineral products, in addition, also can be used for engineering geologic investigation, survey for the purpose of locating hydrogeological resources, the generaI investigation of oil gas field and exploration and well Drilling etc.In prior art, rock-core borer brake is undesirable, and operation can not be satisfied the demand.
Summary of the invention
The object of the present invention is to provide a kind of good braking effect, rock-core borer break simple to operate.
Object of the present invention can be achieved through the following technical solutions:
A kind of rock-core borer break, comprises housing, is provided with the strap of the brake in described housing; Described strap of the brake ring wall is connected with two relative brake shoes; Brake shoe described in two runs through and is provided with the second bolt; Second described bolt one end and cam are rotationally connected; The second described bolt upper end portion is provided with pad and copper packing, and underpart is provided with hexagon nut and the inclined nut of hexagonal; On the second bolt between two brake shoes, cover has spring.
Described housing is bolted on support by first, and pedestal lower end is fixed on rock-core borer by hexagon head bolt.
Described cam side has sawtooth, and this sawtooth and the ratchet be fixed on housing engage each other.
Described cam is provided with hand handle, and when handle rotation is near housing, the position relative at housing is provided with pad.
The end face of the second described bolt the other end is relative with push rod bolt, and push rod bolt is provided with nut.
Beneficial effect of the present invention: the present invention, by the effect of cam to the second bolt, extrudes two brake shoes, carries out compression brake further to the strap of the brake, realizes operation fast, the effect of good braking effect.
Accompanying drawing explanation
For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic side view of the present invention.
Embodiment
As depicted in figs. 1 and 2, a kind of rock-core borer break, comprises housing 15, and housing 15 is fixed on support 12 by the first bolt 18, and support 12 lower end is fixed on rock-core borer by hexagon head bolt 13.
Housing 15 inwall is fixed with the strap of the brake 11 by sunk head rivet 14.
Outside the strap of the brake 11, ring wall is connected with two relative brake shoes 7, two brake shoes 7 run through and is provided with second bolt 9, second bolt 9 one end and has connecting ring, this connecting ring is connected with cam 2 by bearing pin 4, be provided with copper sheathing 3 between connecting ring and bearing pin 4, cam 2 is provided with a hand 1.Cam 2 side has sawtooth, and this sawtooth and the ratchet 17 be fixed on housing 15 engage each other.When hand rotates near housing 15 1, be provided with pad 16 in the position that housing 15 is relative.
The end face of second bolt 9 the other end is relative with push rod bolt 10, and push rod bolt 10 is provided with nut 21.
The second bolt 9 outside upper end portion brake shoe 7 is provided with pad 6 and copper packing 5, the second bolt 9 outside underpart brake shoe 7 is provided with the inclined nut 20 of pad 6, hexagon nut 19 and hexagonal.On the second bolt 9 between two brake shoes 7, cover has spring 8.
Working method: whole break is fixed on rock-core borer by support 12.During braking, rotate hand 1, hand rotates 1 driving cam 2, and cam 2 drives the second bolt 9, the pad 6 at the second bolt 9 two end part, copper packing 5, hexagon nut 19 and the inclined nut 20 of hexagonal extrude two brake shoes 7, two brake shoes 7 move in opposite directions, reduce the diameter of the strap of the brake 11, make the strap of the brake 11 carry out compression fastening, play braking action, pull ratchet 17, make it engage with cam 2, make it turn round.Being used for of spring 8 prevents two brake shoe 7 excessive compression, to squeezing into row buffering.Push rod bolt 10 plays position-limiting action to the second bolt 9.When not needing braking, pull open ratchet 17, revolution hand is 1, and spring 8 rebound effect, loosens the strap of the brake 11.The present invention, by the effect of cam to the second bolt, extrudes two brake shoes, carries out compression brake further to the strap of the brake, realizes operation fast, the effect of good braking effect.
Above content is only to structure example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
