Abstract
The utility model discloses a roller bit of a cylindrical drill. The roller bit of the cylindrical drill comprises a cone palm and a cone. The cone is fixed to one end of the cone palm. The roller bit further comprises an installation base, an installed groove is formed in the installation base, bosses are arranged on the inner walls of the installation groove, one or more connecting piece grooves are formed in the boss on each side in the installation groove, a groove is formed in the side wall of the end, away from the cone, of the cone palm, the end, away from the cone, of the cone palm is inserted into the installation groove of the installation base, the bosses on the inner walls of the installation grooves are located in the groove of the cone palm, and the two sides of the cone palm are respectively provided with one or more connecting pieces passing through the connecting piece grooves in the installation base. According to the roller bit, the installation base is provided, and the cone palm is detachably connected with the installation base. When the roller bit is used, firstly, the installation base is welded to the cylindrical drill, if the cone is damaged and needs to be replaced, the cone palm and the cone are disassembled, a new cone palm and a new cone are installed, and therefore a drill bit is replaced; replacement is convenient, the speed is high, and the working efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of cylinder for rotary drilling rig operation and bores, the particularly rock bit of a kind of brill.
Background technology
Along with the quickening of the Foundation Design paces of construction such as China's high speed, high ferro, bridge, the application of rotary drilling rig is more and more extensive, along with construction stratum becomes increasingly complex, in engineering, often run into harder bedrock formation, large erratic boulder layer and hard permafrost soil layer, if directly with augers or revolve and dig drill bit and creep into more difficult, need to first go out annular groove with the drilling of gear wheel cylinder, then be used in conjunction with augers or revolve and dig drill bit and creep into.Therefore, revolve dig gear wheel cylinder bore start to be widely used on severe firm hard formation construction operation, thereupon, the market demand of rock bit of boring main cutting element as cylinder is increasing, but up till now, also do not have specialized company's production to revolve and dig a cylinder brill rock bit, rock bit major part used is the second-hand old tricone bit of selecting on market on petroleum drilling digging machine under eliminating, and rock bit is welded direct on a brill wall and is used, and the old rock bit life-span is shorter, once damage, workman need cut off rock bit with flame gas, and then new rock bit is welded on a brill wall, each replacing workload is large, not only time-consuming but also require great effort, delay programming.
Summary of the invention
The purpose of this utility model is: a kind of rock bit that more cylinder of bit change bores that is easy to is provided.
In order to solve the problems of the technologies described above, the utility model comprises cone palm and gear wheel, gear wheel is fixed on one end of cone palm, also include mount pad, mount pad is provided with mounting groove, the inwall of mounting groove is provided with boss, on the boss of each side in mounting groove, be equipped with one or more connector grooves, sidewall away from one end of gear wheel on cone palm is provided with groove, on cone palm, be inserted in the mounting groove of mount pad away from one end of gear wheel, in the groove of boss on the inwall of mounting groove in cone palm, the both sides of cone palm are respectively provided with one or more by the connector of the connector groove on mount pad.
Insert and exit mount pad for the ease of cone palm, described mounting groove is U-shaped or V-shaped groove.
Firm in order to connect, described connector is spring catch.
Firm in order to connect, the both sides of described cone palm are respectively provided with a connector hole, and the opposite side of groove is led in connector hole from a side of groove, and connector is arranged in connector hole.
The beneficial effects of the utility model: the novel mount pad that is provided with of this reality, cone palm can be connected with mount pad in demolition, in use, first mount pad is welded in drilling pipe, need to change as gear wheel is damaged, pull down that cone palm and gear wheel refill a new cone palm and gear wheel has just been realized more bit change, it is convenient to change, speed is fast, greatly increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of part 3 and part 4;
Fig. 3 is the structural representation of part 1;
In figure: 1, mount pad, 2, spring catch, 3, cone palm, 4, gear wheel, 1-1, boss, 1-2, connector groove, 3-1, groove, 3-2, pin-and-hole.
The specific embodiment
A kind of specific embodiment as Figure 1-3, it comprises cone palm 3, gear wheel 4 and mount pad 1, gear wheel 4 is fixed on one end of cone palm 3, mount pad 1 is provided with mounting groove, the inwall of mounting groove is provided with boss 1-1, on the boss 1-1 of each side in mounting groove, be equipped with a connector groove 1-2, sidewall away from one end of gear wheel 4 on cone palm 3 is provided with groove 3-1, on cone palm 3, be inserted in the mounting groove of mount pad 1 away from one end of gear wheel 4, in the groove of boss 1-1 on the inwall of mounting groove in cone palm 3, the both sides of cone palm 3 are respectively provided with one by the connector of the connector groove 1-2 on mount pad 1.
Mounting groove adopts U-lag.Connector is spring catch 2, also can adopt common pin or taper bolt to replace.The both sides of cone palm 3 are respectively provided with one or more pin-and-hole 3-2, if adopt other connector, pin-and-hole 3-2 should change the connector hole matching with connector into, pin-and-hole 3-2 leads to the opposite side of groove 3-1 from a side of groove 3-1, spring catch 2 is arranged in pin-and-hole 3-2, and pin-and-hole 3-2 also can only be arranged on a side of groove 3-1.
Using method: mount pad 1 is welded on a drilling pipe wall, then cone palm 3 is inserted on mount pad 1, then two spring catch are installed.In the time that gear wheel 4 damages, first pull down two spring catch, then pull up cone palm 3, then a new cone palm that is fixed with gear wheel 43 is installed on mount pad 1.
