Abstract
The utility model relates to a two -way splitting stick is mainly become by hydraulic motor, drive gear, screw rod, transmission piece, link mechanism, propulsion post, outer shell body group, and hydraulic motor passes through drive gear and transmits the moment of torsion for the screw rod, screw rod both ends and outer shell body coupling to can be at the internal portion's free rotation of outer shell, the transmission piece converts the circumference rotary motion of screw rod into axial linear motion, and then drive connecting rod mechanism will advance the post to release outer cylinder body completion splitting operation. The utility model discloses equipment structure is simple, and the maintenance of being convenient for maintains that double propulsion post symmetry atress improves work efficiency, has avoided the harm of the external cylinder body of reaction force simultaneously.
Description
Technical field
The utility model belongs to technical field of engineering machinery, is specifically related to a kind of two-way splitting rod.
Background technique
Splitting machine is a kind of machine for field division materials such as ore extraction, building, engineering constructions, and its functional part playing splitting action is the splitting rod of splitting machine.Existing hydraulic splitting rod is primarily of cylinder component, wedge device and split block composition, and the piston driving piston rod relying on in-oil cylinder highly pressurised liquid to promote in cylinder component does linear reciprocating motion, thus promotes wedge device and do linear reciprocating motion and reach division object.But hydraulic splitting rod in use exists following problem: it is first-class that (1) cylinder component internal structure complexity comprises oil inlet pipe, oil suction chamber, return tube, oil back chamber and high-voltage connecting, maintain very inconvenient; (2) during work, oil pressure reaches 120MPa, and oil pipe and seal ring tolerate comparatively hightension, and need often maintenance or regularly replace oil pipe and seal ring, maintenance cost is larger; (3) piston rod does reciprocating impact motion, and working stability need to improve.
Model utility content
In order to solve the problem, the utility model provides a kind of two-way splitting rod, its object is to solve the problems such as the maintenance of existing splitting rod is inconvenient, working stability is low.
Technical solutions of the utility model:
A two-way splitting rod, comprises oil hydraulic motor, driving gear, screw rod, drive block, linkage mechanism, propelling post, outer cylinder body; Described driving gear is made up of the actuation gear of connecting fluid pressure motor and the driven gear of connecting screw rod.
Be processed with 4-8 group screw thread above described screw rod, often organize screw thread and divide upper and lower two-part, and two-part thread rotary orientation be contrary, when bolt rotary, often two drive blocks being threaded of group are simultaneously toward intermediary movements.
Described drive block is enclosed within screw rod outside, and the motion that rotates in a circumferential direction of screw rod can be converted to axial linear movement, and then propelling post release outer cylinder body is completed cleavage operations by drivening rod mechanism.
Described screw rod two ends are connected with outer cylinder body pin, and screw rod can cylinder interior rotate freely around own axes outside.
Described outer cylinder body is provided with and advances post manhole appendix.
The beneficial effect that the utility model has is:
1, be straight line motion by screw-driven by the convert rotational motion of oil hydraulic motor, and utilize linkage mechanism to complete propelling action, stable working is reliable, and propelling force is large;
2, replace original hydraulic cylinder extension to move with screw-driven, mechanism's configuration is more simple, and maintenance service is more convenient;
When 3, carrying out splitting, double propelling column symmetry is stressed, increases work efficiency, and avoids the infringement of reaction force to outer cylinder body simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model internal structure schematic diagram.
In figure, 1 oil hydraulic motor, 2 actuation gears, 3 driven gears, 4 screw rods, 5 drive blocks, 6 linkage mechanisms, 7 advance post, 8 outer cylinder bodies.
Embodiment
Below in conjunction with accompanying drawing, further description is done to the utility model.
The two-way splitting rod of one as shown in Figures 1 and 2, comprises oil hydraulic motor 1, driving gear, screw rod 4, drive block 5, linkage mechanism 6, advances post 7, outer cylinder body 8; Described driving gear is made up of the actuation gear 2 of connecting fluid pressure motor and the driven gear 3 of connecting screw rod, and the moment of torsion of oil hydraulic motor 1 is passed to screw rod 4 by it; Described screw rod 4 two ends are connected with outer cylinder body 8, and can rotate at outer cylinder body 8 internal freedom; It is outside that described drive block 5 is enclosed within screw rod 4, and the motion that rotates in a circumferential direction of screw rod 4 can be converted to axial linear movement, and then propelling post 7 is released outer cylinder body 8 and completed cleavage operations by drivening rod mechanism 6.
Wherein, described screw rod 4 is provided with 4-8 group screw thread above, and the present embodiment accompanying drawing is shown as 5 groups of screw threads, often organize screw thread and divide upper and lower two-part, and two-part thread rotary orientation is contrary, when screw rod 4 rotates, two drive blocks 5 that often group is threaded can simultaneously toward intermediary movements.
Working procedure of the present utility model comprises the steps:
(1) primer fluid pressure motor 1, oil hydraulic motor 1 is rotated by driving gear drive screw 4;
(2) drive block 5 does straight line motion in opposite directions respectively under the drive of screw rod 4, and then propelling post 7 is released outer cylinder body 8 and completed cleavage operations by drivening rod mechanism 6;
(3) reverse hydraulic motor 1 makes propelling post 7 do fallback action, reclaims splitting rod.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
