Description

Technical Field

[0001] The utility model relates to the field of installation of material inlet and outlet valves, in particular to a docking compensation device for an actuator of a discharge port ball valve. Background Art

[0002] As daily waste volumes increase, the scale of newly built waste transfer stations is also increasing, increasing the workload for waste collection, transportation, and sanitation personnel within these stations. Waste treatment equipment is also becoming increasingly sophisticated, leading to increasingly complex and specialized equipment types, larger and larger equipment sizes, and a higher level of automation requirements. Unmanned operation is becoming a future trend.

[0003] In the process of unmanned operation improvement, the original equipment in the garbage transfer station is also being transformed, updated or upgraded. In the existing technology, after the garbage compression box is full of garbage and arrives at the garbage transfer station, the garbage needs to be squeezed and the squeezed liquid is discharged into the sewage tank for temporary storage, and then the solid garbage and liquid garbage are classified and processed separately to achieve reasonable utilization or pollution-free discharge.

[0004] During the modification of the above-mentioned docking method, in order to realize the automatic docking between the discharge port of the garbage compression box and the inlet of the sewage tank, an automatic docking device is set up next to the sewage tank in the garbage station. When the garbage compression box enters the garbage station and approaches the sewage tank, a predetermined entry route is set so that the garbage compression box stops within the predetermined position range, and the discharge port is aligned with the interface of the automatic docking device. The automatic docking device is provided with a telescopic docking pipe connected to the suction pipeline of the sewage tank inlet. The telescopic docking pipe is driven by a cylinder to make the interface part move forward and gradually approach the discharge port of the garbage compression box for docking until close contact and successful docking. Then, the discharge port valve and the suction valve on the suction pipeline are opened to start squeezing and draining. The above-mentioned docking device realizes automatic docking and pipeline opening without human intervention. However, in actual use, there are deviations in the installation positions of the discharge ports of different compression boxes, which affect the tightness of the interface. Sometimes, additional compensation structures are required to achieve precise docking. Utility Model Content

[0005] The utility model aims to solve the problem of docking position deviation of different compression boxes in the improvement of the automatic docking scheme of the discharge port of the garbage compression box and the liquid receiving port of the sewage tank in the existing technology, and provides a discharge port ball valve actuator docking compensation device to adapt to the position deviation of the discharge port of different garbage compression boxes.

[0006] The purpose of the present utility model is achieved in this way. A discharge port ball valve actuator docking compensation device comprises a ball valve and an actuator, wherein the ball valve is connected to the discharge port of a discharge box, and the actuator is connected to the side of the receiving port of a material receiving device. A protrusion is provided on the valve stem of the ball valve, and a concave block is provided at the output end of the actuator. When the discharge port of the material box and the receiving port of the material receiving device are horizontally docked, the protrusion and the concave block are engaged. It is characterized in that a connecting base plate is provided on the side of the receiving port of the material receiving device, and the connecting base plate is used to install the actuator, and a compensation structure for compensating for the horizontal engagement azimuth deviation of the protrusion and the concave block is provided between the actuator and the connecting base plate.

[0007] In order to achieve horizontal position compensation, the compensation structure includes an upper base plate parallel to the connecting base plate, and two horizontal guide shafts are supported between the upper base plate and the connecting base plate. The axial direction of the guide shaft is perpendicular to the horizontal engagement direction of the protrusion and the concave block, and the two ends of the guide shaft are supported by supports respectively. Two sliders are respectively provided on the lower surface of the upper base plate at positions corresponding to each guide shaft, and the sliders are slidably connected to the guide shafts. A compression spring is provided on the guide shaft between each slider and the adjacent support, and the compression springs on both sides elastically squeeze the sliders respectively to compensate for the position deviation when the protrusion and the concave block are horizontally engaged.

[0008] Furthermore, a guide sleeve is provided at the position where the slider cooperates with the guide shaft, and the guide shaft slides through the guide sleeve.

[0009] To facilitate the fixed installation of the actuator, two parallel fixed plates for supporting the installation of the actuator are fixed on the upper side of the upper base plate. The actuator is fixed between the fixed plates. The rotating output shaft of the actuator is arranged vertically downward relative to the upper base plate. The concave block is fixed to the end of the output shaft. An upper through-hole is provided at the corresponding position of the upper base plate for facilitating the passage of the concave block. A lower through-hole is provided at the position of the connecting base plate corresponding to the concave block. The concave block is displaced through the lower through-hole, and a space is provided along the compensation direction to facilitate compensation displacement of the periphery of the mating part of the protrusion and the concave block.

[0010] The present invention relates to a discharge port ball valve actuator docking compensation device, in which the ball valve is connected to the discharge port of the discharge box, is normally closed in the non-discharge state, and moves as a whole with the discharge port. The actuator for switching the ball valve is connected to the side of the receiving box. When the discharge box needs to discharge materials, it approaches the receiving box along a predetermined trajectory, and the receiving port end of the receiving box gradually docks with the receiving device. During the docking process, the protrusion and the concave block gradually approach each other. When there is a position deviation in another horizontal direction in the horizontal plane during the engagement process, the compression spring in the compensation structure elastically presses the slider to adaptively offset the position of the upper base plate on the upper side of the slider, driving the actuator to move horizontally and adjust the position so that the concave block and the convex block are completely engaged, thereby compensating for the horizontal position deviation and ensuring the tightness of the docking structure. After docking, the actuator then operates to open the ball valve to connect the discharge port and the discharge receiving pipeline. Therefore, the beneficial effect of the discharge port ball valve actuator docking compensation device of the present invention is that the position compensation structure in which the pressure springs on both sides press against the slider can compensate and adjust the position deviation of the discharge outlet within a range, thereby achieving precise and tight docking.

The actuator 2 is connected to the side of the receiving port 101 of the receiving device 1. The valve stem of the ball valve 7 is provided with a protrusion 5, and the output end of the actuator 2 is provided with a recessed block 6. When the discharge port of the material box and the receiving port 101 of the receiving device are horizontally docked, the protrusion 5 and the recessed block 6 are engaged, so that the driving end of the actuator 2 is connected to the valve stem of the ball valve 7 by driving. The ball valve can be opened and closed by the action of the actuator 2. To facilitate the connection of the actuator, a connecting base plate 3 is provided next to the receiving port 101 of the receiving device 1.
