Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distributors, in particular to a double-cylinder electro-hydraulic three-way distributor. Background Art
[0002] The electro-hydraulic three-way distributor uses an electro-hydraulic push rod as a power source. The electro-hydraulic push rod drives the rotating shaft mechanism of the three-way distributor to control the flipping of the flap to achieve the effect of material reversal.
[0003] At present, the electro-hydraulic three-way distributors all use an integral straight electro-hydraulic push rod, and use an oil cylinder to push the flap to flip; when the size of the tee is large, such as the flange size under the wood chip screen of the paper mill is relatively large, the length can reach 5000mm, and the width of the tee under the wood chip screen is also relatively long, the size is 3000mm. If a single-cylinder integral electro-hydraulic push rod is used to push the flap, only one end of the flap shaft is affected by the oil cylinder, which can easily lead to inconsistent forces at both ends of the flap shaft, resulting in bending of the flap shaft or the flap cannot be flipped stably. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a double-cylinder electro-hydraulic three-way distributor with a reasonable structural design, which can ensure that the two ends of the flap shaft are evenly stressed and the flaps can be turned stably and reliably.
[0005] In order to solve the above technical problems, the technical solution of the utility model is: a double-cylinder electro-hydraulic three-way distributor, including a shell, a feed channel and two diversion channels are arranged in the shell, a flap for closing the diversion channel is arranged in the shell, and the flap is installed on the rotating shaft; bearing seats are respectively installed on both sides of the shell, and the two ends of the rotating shaft respectively pass through the shell and are rotatably installed on the bearing seats; it also includes a double-acting drive mechanism, and the double-acting drive mechanism simultaneously causes the two ends of the rotating shaft to rotate due to force, and the flap is driven to rotate when the rotating shaft rotates.
[0006] As a preferred technical solution, the double-acting drive mechanism is a double-cylinder split electro-hydraulic push rod, which includes a motor, a hydraulic pump and two cylinders. The hydraulic pump and the two cylinders are split structures, and the hydraulic pump is connected to the two cylinders respectively through pipelines.
[0007] As a preferred technical solution, cylinder supports are installed on both sides of the shell, and two cylinders are installed on the cylinder supports on the corresponding sides. The telescopic ends of the two cylinders are correspondingly connected to the two ends of the rotating shaft through connecting rods.
[0008] As a preferred technical solution, limit switches are respectively provided on the two oil cylinders.
[0009] As a preferred technical solution, the shell is in a herringbone shape.
[0010] Due to the adoption of the above technical scheme, the utility model has at least the following beneficial effects: bearing seats are respectively installed on both sides of the shell, and the two ends of the rotating shaft respectively penetrate the shell and are rotatably installed on the bearing seats; when the material is reversed, the two ends of the rotating shaft are simultaneously subjected to force and rotated through the double-acting drive mechanism, so that the two ends of the flap rotating shaft can be subjected to force at the same time and the force is uniform, which can avoid bending of the flap rotating shaft and ensure that the flap is turned stably and reliably; a double-cylinder split electro-hydraulic push rod is adopted, which has a simple structure, convenient installation, convenient cylinder extension and retraction control, and good working stability.

[0014] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.
[0015] like Figure 1 and Figure 2 As shown, a double-cylinder electro-hydraulic three-way distributor comprises a shell 1, in which a feed channel 11 and two diversion channels 12 are arranged, and the shell 1 is in a herringbone structure as a whole; a flap 2 for closing the diversion channel 12 is arranged in the shell 1, and the flap 2 is mounted on a rotating shaft 3; bearing seats 4 are respectively mounted on both sides of the shell 1, and both ends of the rotating shaft 3 respectively pass through the shell 1 and are rotatably mounted on the bearing seats 4; a double-acting drive mechanism is also included, and the double-acting drive mechanism simultaneously causes the two ends of the rotating shaft 3 to rotate under force, and the rotating shaft 3 drives the flap 2 to rotate when it rotates.
[0016] In this embodiment, the double-acting drive mechanism is a double-cylinder split electro-hydraulic push rod 5, which includes a motor 51, a hydraulic pump 52 and two oil cylinders 53. The hydraulic pump 52 and the two oil cylinders 53 are split structures. The hydraulic pump 52 is connected to the two oil cylinders 53 through pipelines (oil pipes). The motor 51 drives the bidirectional hydraulic pump to output pressure oil in both directions through forward and reverse rotation, and sends it to the two oil cylinders 53 through hydraulic control valves and pipelines to realize the reciprocating motion of the piston rod. Cylinder supports 54 are installed on both sides of the housing 1, and the two oil cylinders 53 are installed on the cylinder supports 54 on the corresponding sides. The telescopic ends of the two oil cylinders 53 are connected to the two ends of the rotating shaft 3 through connecting rods 55.
[0017] When the tee is performing material reversing operation, the two ends of the rotating shaft 3 are subjected to force and rotated by extending and retracting the two oil cylinders 53. In this way, the two ends of the flap rotating shaft can be subjected to force at the same time and the force is uniform, thereby avoiding bending of the rotating shaft 3 and ensuring stable and reliable flipping of the flap. A double-cylinder split electro-hydraulic push rod is adopted, which has a simple structure and is easy to install. Limit switches are respectively arranged on the two oil cylinders, and the extension and retraction of the oil cylinders are convenient to control, and the working stability is good.
[0018] The double-cylinder electro-hydraulic three-way distributor can be used for wood chip diversion under the wood chip screen in paper mills. When the size of the three-way is too large, the rotating shaft can be turned stably and reliably, the operation and control are convenient, and the service life is long.
[0019] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
