Description

Technical Field

[0001] The invention relates to the technical field of cement processing, in particular to a cement lifting device. Background Art

[0002] Cement is an indispensable material in building materials. In the cement industry, elevators are often used to transport cement from low places to high places. On the cement packaging conveyor line, a cement elevator with higher operating flexibility is needed to complete the lifting and loading of cement, and cooperate with the cement packaging conveyor line for transportation and complete the subsequent packaging of cement materials. However, the current cement elevator has poor operating effect and cannot meet the needs of use. Therefore, a cement lifting device that is easy to operate is needed.

[0003] The existing publication number CN112919009B discloses a lifting device and a lifting method for storing cement, wherein the lifting device for storing cement includes a box body provided with a feed port and a discharge port, and a lifting chain rotatably arranged in the box body, a lifting hopper is installed on the lifting chain, and the lifting hopper includes a hopper body and a fixed block fixedly connected to the lifting chain, a slide groove extending vertically is provided on the fixed block, a slider fixedly connected to the bucket body is slidably arranged in the slide groove, the lower end of the slider is connected to the bottom plate of the slide groove by an impact spring, a limit plate located above the slider is fixed on the fixed block, and the distance between the slider and the limit plate is less than the length of the impact spring in the natural state. The present invention accelerates and blocks the bucket body when throwing materials by arranging an impact spring and a limit plate, thereby increasing the speed difference between the bucket body and the cement and improving the throwing effect; by arranging a load-bearing plate and a proximity sensor, a material shortage alarm in the box body is realized by utilizing the principle of a lever, so that the staff can understand the feeding situation into the box body conveniently.

[0004] When the current cement lifting device is used to lift and transport cement, the landing point of the cement is the same each time after lifting. There is insufficient space for lateral movement during the lifting process, which is not conducive to unloading at multiple landing points on the conveyor line. In addition, the lifting device and the conveyor line are used in coordination with each other, which is not conducive to adjusting the setting distance between the lifting device and the conveyor line, so that the cement affects the packaging conveyor line during the loading and lifting process.

[0007] (II) Technical solution

[0008] In order to achieve the above-mentioned purpose of achieving height lifting and lateral movement at the same time, realizing unloading at multiple landing points, and also avoiding the impact on the packaging conveyor line during the loading process, the present invention provides the following technical scheme: comprising a lifting machine base, a push seat is arranged on the front side of the lifting machine base, and a hydraulic cylinder four is movably connected between the push seat and the lifting machine base, a packaging conveyor line is installed on the front side of the push seat, a lifting frame is hingedly installed on the top of the lifting machine base, and a lifting arm is movably connected to the upper end of the lifting frame, a rotating shaft for movement is arranged between the lifting arm and the lifting frame, a hydraulic cylinder three is movably installed between the lower surface of the lifting arm and one side of the lifting frame, and a hydraulic cylinder two is installed below the hydraulic cylinder three, a descending frame is installed on the right end of the lifting arm, and a moving seat is movably installed on the surface of the descending frame, an extension frame is connected to one side of the moving seat, and a moving sleeve is movably installed on the surface of the extension frame, a supporting arm is installed at the bottom of the moving sleeve, and a mounting frame is installed at one end of the supporting arm, a cement bucket is installed below the mounting frame, and an ash unloading bucket is installed at the lower end of the cement bucket.

[0009] Preferably, the lifting machine base and the lifting frame are rotatably connected via a shaft, and the right side of the lifting frame is movably connected to one end of the second hydraulic cylinder.

[0010] Preferably, one end of the lifting arm is rotatably connected to the upper end of the lifting frame via a rotating shaft, and the lifting arm and the lifting frame are movably connected to the two ends of the hydraulic cylinder three respectively.

[0011] Preferably, a first directional wheel is movably mounted on the upper end of the lifting frame, and a second directional wheel is mounted on one side of the first directional wheel.

[0012] Preferably, a third directional wheel is installed on the right end surface of the lifting arm, and a fourth directional wheel is installed below the third directional wheel.

[0013] Preferably, main cables are inserted between the surfaces of the first directional wheel, the second directional wheel, the third directional wheel and the fourth directional wheel, and a second winding machine is installed at the left end of the main cable.

[0014] Preferably, an auxiliary cable is arranged below the main cable, and the left end of the auxiliary cable is connected to a winding machine, the right end of the main cable and the right end of the auxiliary cable are twisted together, and the right end of the main cable and the right end of the auxiliary cable are both equipped with hooks.

[0015] Preferably, the surface of the movable seat is movably connected to a folding frame, and the inner side of the folding frame is movably connected to a hydraulic cylinder 1.

[0016] Preferably, a sliding connection is formed between the surface of the extension frame and the movable sleeve, and a telescopic cylinder is movably connected to the surface of the movable sleeve.

[0017] Compared with the prior art, the present invention provides a cement lifting device, which has the following beneficial effects:

[0018] 1. Install a push seat on the front side of the lifting base. The push seat and the packaging conveyor line are installed with each other. A hydraulic cylinder four is set between the push seat and the lifting base. The hydraulic cylinder four is used to push the push seat to move, so that the distance between the packaging conveyor line and the lifting base is pulled apart. This is conducive to adjusting the setting distance between the lifting base and the packaging conveyor line. In this way, when the setting distance is pulled apart, it is prevented that the cement bucket on the lifting frame will not splash cement ash on the packaging conveyor line when loading, thereby affecting the packaging conveyor line.

[0019] 2. The lifting frame and the lifting arm are movably connected. With the help of hydraulic cylinder 2 and hydraulic cylinder 3, the expansion angle of the lifting arm is adjusted. The expansion angle of the lifting arm is continuously adjusted to a larger extent, so that the lateral movement distance of the cement bucket installed at one end of the lifting arm is farther, and then the unloading point of the cement bucket will also change, and then unloading is carried out at multiple drop points along the packaging conveyor line to avoid unloading at the same place, which causes a lot of cement materials to accumulate at the same place, affecting the material processing efficiency of the packaging conveyor line itself. By realizing multiple drop points, the efficiency of the cement bucket during lifting and unloading can be improved and the conveying efficiency of the packaging conveyor line can be improved. In addition, a descending frame is installed in the lower end combination of the lifting frame, which is connected to the cement bucket through the descending frame and the supporting arm connected to the descending frame. The height of the cement bucket is adjusted by moving the moving seat up and down on the descending frame. While cooperating with the lateral distance movement of the lifting arm, the height compensation adjustment is realized to ensure that the cement bucket can be accurately unloaded on the packaging conveyor line when unloading.

[0032] Specifically, the first directional wheel 7 and the second directional wheel are rotatably installed on the upper end of the lifting frame 4, and the third directional wheel 10 and the fourth directional wheel 11 are also movably installed on the surface of the lifting arm 5 in cooperation with the lifting frame 4, the main cable 9 and the auxiliary cable 23 are inserted between the first directional wheel 7, the second directional wheel 8, the third directional wheel 10 and the fourth directional wheel 11, and the main cable 9 and the auxiliary cable 23 are oriented and positioned by utilizing the cooperation of the first directional wheel 7, the second directional wheel 8, the third directional wheel 10 and the fourth directional wheel 11, and are installed and connected with the descending frame 12 through the main cable 9 and the auxiliary cable 23 and the hook 28 connected at one end of the main cable 9 and the auxiliary cable 23, and the descending frame 12 and the cement bucket 13 installed on the descending frame 12 are lifted by utilizing the winding and unwinding of the winder 1 24 and the winder 25, and combined with the movable adjustment of the lifting arm 5, the lateral distance adjustment is achieved while also completing the height lifting of the cement.

[0033] When in use, first, the push seat 2 is adjusted by the hydraulic cylinder 29, and the packing conveyor line 3 is pushed to move by the push seat 2, so that the packing conveyor line 3 is kept at a distance from the lifting machine base 1.

In order to prevent the situation where too much cement is unloaded at the same place and causes accumulation, the inclination angle of the lifting frame 4 is adjusted by using the hydraulic cylinder 26. At the same time, the expansion angle of the lifting arm 5 is adjusted by using the hydraulic cylinder 3 27 and the rotating structure between the lifting arm 5 and the lifting frame 4. As the lifting frame 4 and the lifting arm 5 are continuously tilted and expanded to the right, the lateral movement of the cement bucket 13 installed at one end of the lifting arm 5 is The longer the distance is, the more the unloading point of the cement bucket 13 on the packaging conveyor line 3 will change, so that the second unloading point will be farther away from the first unloading point, and so on, the third time will be farther away from the second time, and then unloading will be performed at multiple locations along the packaging conveyor line 3 to avoid the problem of accumulation caused by unloading at the same location. Finally, when the lifting arm 5 moves to the right, with each adjustment of the distance, the height difference between the cement bucket 13 and the packaging conveyor line 3 will also deviate. At this time, the winding machine 1 24 and the winding machine 2 25 are used to wind and release the main cable 9 and the auxiliary cable 23 at the same time. , continue to lift the descending frame 12, and cooperate with the up and down movement of the moving seat 14 on the descending frame 12 to adjust the height of the cement bucket 13, and utilize the mutual cooperation between the folding frame 15 and the hydraulic cylinder 16 to make the moving seat 14 move up and down along the descending frame 12, and cooperate with the lifting of the main cable 9 and the auxiliary cable 23 to perform height lifting and adjustment, so that while cooperating with the lateral distance adjustment of the lifting arm 5 and the lifting frame 4, height compensation is performed to make up for the height change difference between the cement bucket 13 and the packaging conveyor line 3, and improve the ash unloading accuracy of the cement bucket 13 on the packaging conveyor line 3.
