Description

Technical Field

[0001] The invention relates to the technical field of multi-way valves, and in particular to a multi-link type multi-way valve operating mechanism. Background Art

[0002] The principle of the multi-way valve is mainly based on the relative movement between the valve core and the valve body to change the on-off relationship of the oil channel connected to the valve body;

[0003] At present, the traditional multi-way valve operation control mechanism can only control the movement of four directions (i.e., two links) with one handle. The control of other links requires additional operating handles. The structural layout is scattered and the operation is cumbersome. The operator needs to be familiar with multiple operating handles, which increases the difficulty of operating the machine and brings great difficulty to the operator. In addition, when using it, the operating handle needs to be replaced, and there will be a time difference in the input of the action execution command, which places great demands on the operator's replacement speed as well as eyesight, physical strength and coordination.

[0004] The existing patent authorization announcement number is: CN104676083B, which discloses a multi-link multi-way valve operating mechanism. The operating handle is connected to the multi-way valve through a four-way double-link mechanism, and the four control circuits of the multi-way valve are controlled by applying four adjacent vertical directions of the same plane to the operating handle; the operating handle is connected to the multi-way valve through a rotating connecting rod mechanism at the same time, and the two control circuits of the multi-way valve are controlled by applying two clockwise and counterclockwise directions of the same plane to the operating handle. The present invention can realize six execution command actions on the operating handle, which correspond to the control action execution components respectively, and complete six operation actions. More operation commands can be realized on the same operating handle, which is convenient for the operation and control of the machine installed with the operating handle; the structure is compact and the operation control is simplified.

Each group of annular sleeves 401 is provided with four, such as Figure 3 , 4 , 5, the array is arranged from left to right, which is the first ferrule, the second ferrule, the third ferrule and the fourth ferrule;

[0038] A rotating shaft 601 is provided at the center of the three groups of pull rods 301. The rotating shaft 601 and the outer wall of the pull rod 301 are slidably connected inside the fixed plate 801. A handle 602 is fixedly connected to one end of the rotating shaft 601. A first hook mechanism 9 and a second hook mechanism 10 are provided on the outer wall of the rotating shaft 601. The first hook mechanism 9 and the second hook mechanism 10 both include a sliding sleeve 501 slidably connected to the outer wall of the rotating shaft 601. The inner wall of the sliding sleeve 501 is provided with transverse sliding grooves 502 all around. Both sides of the middle of the transverse sliding groove 502 are provided with arc-shaped slots 503 communicating therewith.

[0041] During use, when it is necessary to drive one of the three groups of pull rods 301 to work, the handle 602 pushes the rotating shaft 601 to drive the first clamping block 504 to be inserted into the horizontal sliding groove 502 opened on the sliding sleeve 501 of the first hook mechanism 9, which is the first preset position. After the longitudinal clamping block 509 on the first clamping block 504 corresponds to the arc-shaped clamping groove 503, it is rotated counterclockwise to drive the longitudinal clamping block 509 of the first clamping block 504 to be clamped into the arc-shaped clamping groove 503. At this time, the second clamping block 505 is separated from the inner wall of the second hook mechanism 10. The rotating handle 602 drives the rotating shaft 601 and the claw 510 on the outer wall of the first hook mechanism 9 to rotate counterclockwise to select the required The pulling rod 301 is pulled. When the first hook mechanism 9 is located in the counterclockwise direction of the pulling rod 301 to be pulled, the handle 602 is rotated clockwise to drive the claw 510 of the first hook mechanism 9 to be stuck in the annular sleeve 401 distributed on the outer wall of the pulling rod 301. At this time, the longitudinal block 509 on the first block 504 is stuck in the arc-shaped slot 503 on the other side of the transverse slide groove 502. According to the needs, it is selected whether to pull the pulling rod 301 or push the pulling rod 301. The moving distance is the distance between two adjacent annular sleeves 401 in the same group. After the operation is completed, the claw 510 of the first hook mechanism 9 is separated from the annular sleeve 401 by rotating counterclockwise, and the first hook mechanism 9 is driven to reset;

At this time, the first clamping block 504 is separated from the inner wall of the first hook mechanism 9, and the above operation is repeated to select the two groups of pull rods 301 that need to be operated and control them;

[0043] When it is necessary to drive the three groups of pull rods 301 to work simultaneously, the second clamping block 505 is driven to move to the third preset position, the second clamping portion 506 of the second clamping block 505 is inserted into the first hook mechanism 9, and the third clamping portion 507 is clamped into the second hook mechanism 10, the first hook mechanism 9 and the second hook mechanism 10 are connected in series, and the operation of the first preset position is repeated, and the three groups of pull rods 301 that need to be operated are selected, and they are controlled by pulling or pushing the handle 602, so as to simultaneously control the three groups of hydraulic cylinders connected to the multi-way valve body 101;

[0045] Annular limiting plates are fixedly installed on the opposite sides of the sliding sleeve 501 of the first hook mechanism 9 and the second hook mechanism 10. The outer walls of the two annular limiting plates are rotatably connected to a connecting sleeve 515 through a bearing. A bracket 516 is slidably connected to the middle of the outer wall of the connecting sleeve 515. The connecting sleeve 515 can only slide horizontally on the inner wall of the bracket 516; annular plates 517 are fixedly connected to both sides of the outer wall of the connecting sleeve 515.

One end of the return spring 518 is connected to the bracket 516. 6, and the other end is fixedly connected to the inner side of the annular plate 517. When the first hook mechanism 9 and the second hook mechanism 10 translate, the connecting sleeve 515 will be driven to move along the inner wall of the bracket 516. After the corresponding operation is completed, the claws 510 of the first hook mechanism 9 and the second hook mechanism 10 are separated from the annular sleeve 401, and the handle 602 is released. Under the influence of the two sets of reset springs 518, the connecting sleeve 515 will be driven to reset, thereby driving the first hook mechanism 9 and the second hook mechanism 10 to reset;
