Abstract
The invention discloses a dump lifting hydro-cylinder. The dump lifting hydro-cylinder comprises a first cylinder body (1), a self-locking nut (2), a piston (6), a piston rod (7), a cylinder cover (8) and a second cylinder body (16) which are sequentially connected. The side surface of the connection end of the piston rod (7) and the second cylinder body (16) is provided with the cylinder cover (8), a piston guide ring (3) is fixedly connected between the cylinder cover (8) and the connection end of the first cylinder body (1), and the piston guide ring (3) is arranged outside the piston rod (7). According to the dump lifting hydro-cylinder, the cylinder structure is simple; and a guide rod is provided with a corresponding guide device, thereby avoiding the deviation during usage and being easy to use.
Description
Technical field
The present invention relates to the dump truck field, be specifically related to the tipping bucket lift cylinder in dump truck field.
Background technique
In the dump truck field, usually need to use the hydraulic control part, realize tipping bucket lifting, in stop, reset and overload protection.The tipping bucket lift cylinder is the hydraulic control part, existing hydraulic control part be divided into manually operated valve and pneumatic valve realize the hoisting of automobile tipping bucket, in stop and the operation that resets.Hand control valve is arranged on operator cabin driver's seat next door usually, is convenient to the driver and carries out manually-operable, but can cause in the automobile transport pipe long like this, causes vehicle damage in the process of walking easily, and the driver is not easy control.Another kind of pneumatic valve needs oil circuit and gas circuit two-part to form, and air path part also will have control cylinder and control valve, and its control tracheae still will be received operator cabin, and it is not single that power becomes, and structure is very complicated, uses inconvenient.In addition, existing oil cylinder does not arrange the guiding device that special control piston bar slides, and the slip of piston rod is not easy control, is unfavorable for the operation in later stage.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and the tipping bucket lift cylinder is provided, and solves the used cylinder structure complexity of tipping bucket in the prior art, and guide rod does not arrange corresponding guiding device, departs from easily in the use, uses complicated defective.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: the tipping bucket lift cylinder, comprise first cylinder body, self-locking nut, piston, piston rod, cylinder cap and second cylinder body that connect successively, on the side of described piston rod and the second cylinder body connecting end cylinder cap is installed; Be fixedly connected with the piston guide ring between described cylinder cap and the first cylinder body connecting end, the piston guide ring is positioned at the outside of piston rod.
Further, be provided with seal ring between described piston and the piston rod.
Further, between described piston guide ring and the cylinder cap piston rod guide ring is installed, between piston and piston guide ring, piston seal is installed.
Further, be horizontally installed with seal ring, buffering ring, motion bar Sealing and dust ring between described cylinder cap and the piston rod successively.
Further, the described second cylinder body afterbody is equipped with village's cover.
Further, described first cylinder body is provided with pin frontier defense konisphere.
Further, the side of described cylinder cap is provided with hexagon socket head cap screw.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention has the piston guide ring in the outer installment of piston rod, allow the slip of piston rod under the guiding of piston guide ring, finish, prevent that the piston rod glide direction is offset, influence later stage automobile tipping bucket lifting, in stop and reset operation.
2, between first cylinder body and piston, be provided with self-locking nut, cooperate use with piston, prevent that becoming flexible from use appearring in piston, the situation that occurs coming off takes place, and self-locking nut can also play the effect of antidetonation.
Description of drawings
Fig. 1 is plan view of the present invention;
Fig. 2 is plan view of the present invention.
Reference character is expressed as respectively among the figure: 1, first cylinder body; 2, self-locking nut; 3, piston guide ring; 4, seal ring; 5, piston seal; 6, piston; 7, piston rod; 8, cylinder cap; 9, piston rod guide ring; 10, buffering ring; 11, rod seal part; 12, dust ring; 13, pin frontier defense konisphere; 14, hexagon socket head cap screw; 15, village's cover; 16, second cylinder body.
Embodiment
The present invention is further elaborated below in conjunction with accompanying drawing, and embodiments of the invention are not limited thereto.
Embodiment:
As shown in Figure 1, the present invention includes first cylinder body 1, self-locking nut 2, piston 6, piston rod 7, cylinder cap 8 and second cylinder body 16 that connect successively, be provided with seal ring 4 between piston 6 and the piston rod 7.Second cylinder body, 16 afterbodys are equipped with village's cover 15.First cylinder body 1 is provided with pin frontier defense konisphere 13.On the side of the piston rod 7 of present embodiment and second cylinder body, 16 connecting ends cylinder cap 8 is installed, is horizontally installed with seal ring 4, buffering ring 10, motion bar Sealing 11 and dust ring 12 between cylinder cap 8 and the piston rod 7 successively.The side of cylinder cap 8 is provided with hexagon socket head cap screw 14.Be fixedly connected with piston guide ring 3 between the cylinder cap 8 of present embodiment and first cylinder body, 1 connecting end, piston guide ring 3 is positioned at the outside of piston rod 7, between piston guide ring 3 and the cylinder cap 8 piston rod guide ring 9 is installed, between piston 6 and piston guide ring 3, piston seal 5 is installed.
Outer installment at piston rod has the piston guide ring, in order to guide the slip process of piston rod, prevents from that piston rod from sliding to be offset, influence tipping bucket realization lifting, in stop and reset operation.Connect by self-locking nut between piston and first cylinder body simultaneously, prevent piston work relax, play the effect of antidetonation.This apparatus structure is simple, and is easy to use, practical.
Just can realize this invention as mentioned above.
