Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Example 1: As Figures 1 to 4 As shown, an electric stacker includes a base 1, a frame 2, a lifting frame 3, and a lifting drive mechanism 4. The frame 2 is fixedly mounted on the base 1, the lifting frame 3 slides vertically with the frame 2, and the lifting drive mechanism 4 is used to drive the lifting frame 3 to move vertically.

[0025] In this embodiment, the lifting drive mechanism 4 includes a hydraulic cylinder 41 and a chain 42. The cylinder body 411 of the hydraulic cylinder 41 is fixedly mounted on the base 1. The top end of the telescopic rod 412 of the hydraulic cylinder 41 is provided with a fixed pulley 43 and a mounting bracket 5. The cylinder body 411 is connected to the lifting frame 3 through the chain 42. The middle part of the chain 42 presses on the fixed pulley 43. The mounting bracket 5 is provided with a cylinder 6 and an oil storage tank 7. The cylinder 6 is used to drive the oil storage tank 7 to move up and down. The bottom of the oil storage tank 7 is provided with an outlet hole 71, a sealing plug 72 and a pulling member 8. The sealing plug 72 is located inside the oil storage tank 7 and covers the outlet hole 71. The pulling member 8 is connected to the sealing plug 72. When cylinder 6 drives oil tank 7 downward, pulling member 8 pulls sealing plug 72 to separate it from outlet hole 71, allowing lubricating oil in oil tank 7 to flow out from outlet hole 71 directly and continuously onto chain 42 for lubrication. At this time, cylinder 41 controls lifting frame 3 to move up and down, causing chain 42 to move and lubricate different parts of chain 42. Because the lubricating oil output is continuous, it avoids situations where there is insufficient lubricating oil in certain areas. The outlet hole 71 is located directly above the fixed pulley 43.

[0026] Example 2: Figures 3 to 5 As shown, the rest of the parts are the same as in Embodiment 1, except that the pulling member 8 includes a mounting plate 81 located inside the oil storage tank 7. A first connecting rod 82 and two second connecting rods 83 distributed on the left and right sides of the first connecting rod 82 are fixedly provided on the lower end surface of the mounting plate 81. The lower end of the first connecting rod 82 is connected to the sealing plug 72. The lower end of the oil storage tank 7 is provided with two through holes 73 corresponding to the two second connecting rods 83. The second connecting rods 83 pass through the corresponding through holes 73 and are waterproof and sealed with the through holes 73. A sprocket 84 is rotatably provided between the bottoms of the two second connecting rods 83. The sprocket 84 is located between the liquid outlet hole 71 and the fixed pulley 43. As cylinder 6 starts and moves oil tank 7 downward, sprocket 84 moves down and engages with chain 42. As it continues to move downward, sealing plug 72 separates from outlet hole 71, and lubricating oil in oil tank 7 flows out from outlet hole 71, first onto sprocket 84, and then onto chain 42 for lubrication. At this time, cylinder 41 controls the lifting frame 3 to move up and down, causing chain 42 to move. Simultaneously, sprocket 84 rotates, allowing lubricating oil to lubricate different parts of chain 42. The sprocket 84 accelerates the penetration of lubricating oil into the chain 42. The perforation 73 and the second connecting rod 83 are connected by a waterproof sealing ring, a conventional technical method.

[0027] In this embodiment, the bottom of the second connecting rod 83 is provided with a shaft hole 831, and the center of the sprocket 84 is provided with a sprocket shaft 841. The two ends of the sprocket shaft 841 correspond one-to-one with the two shaft holes 831 and are rotatably connected.

[0028] In this embodiment, a sleeve 74 is fixedly installed on the inner top surface of the oil reservoir 7. A compression spring 75 and a pressure rod 76 are installed inside the sleeve 74. The compression spring 75 is located between the inner bottom surface of the sleeve 74 and the upper end surface of the pressure rod 76. The lower end of the pressure rod 76 extends out of the sleeve 74 and presses against the upper end surface of the mounting plate 81, so that the sealing plug 72 can stably seal the liquid outlet 71 during non-lubrication operations, avoiding the leakage of lubricating oil and ensuring good reliability.

[0029] Example 3: Figures 2 to 4 As shown, the rest of the components are the same as in Embodiment 1, except that the mounting frame 5 includes two side plates 51 distributed on both sides of the top of the telescopic rod 412. Side arms 52 are mounted on the side plates 51. The oil tank 7 is located between the two side arms 52 and slides vertically with the side arms 52. A cylinder 6 is fixedly mounted on one side plate 51, and the push rod of the cylinder 6 is fixedly connected to the lower end face of the oil tank 7. The sliding vertical engagement between the side arms 52 and the oil tank 7 helps improve the stability of the structure.

[0030] In this embodiment, the upper end of the oil storage tank 7 is provided with an injection port 77 and a cap 78 covering the injection port 77.

[0031] In this embodiment, a rotating seat 44 is fixedly provided at the top end of the telescopic rod 412, and a fixed pulley 43 is rotatably provided on the rotating seat 44.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
