Description

Technical Field

[0001] This utility model relates to an improved anode guide rod lifting device for multifunctional units. Background Technology

[0002] In aluminum electrolysis production, multi-functional units (commonly known as multi-functional overhead cranes) are generally used to lift anode guide rods. Traditional anode guide rod lifting devices typically use a scissor-opening method, but this is not very safe and can easily lead to guide rod detachment, causing equipment damage and personnel injuries. Therefore, some users have switched to a single-pin through-type structure, which has a pin hole at the upper end of the guide rod for the lifting pin of the lifting device to pass through, thus solving the lifting safety problem. However, in current lifting devices, the lifting pin is generally inserted manually, which is not only cumbersome and time-consuming, but also prone to slight deformation with use. If the pin hole of the anode guide rod is not perfectly coaxial with the corresponding pin hole of the lifting device, it will increase the difficulty of inserting and removing the lifting pin, often resulting in jamming or other problems. Furthermore, because the lifting pin is long, it is difficult to ensure that its axis is coaxial with the pin hole during manual insertion, which also increases the difficulty of insertion. Utility Model Content

[0003] The purpose of this utility model is to provide an improved multi-functional anode guide rod lifting device for generator sets. Through the guidance of the hydraulic cylinder and the guide rod mechanism and the setting of the guide wheel group, it can ensure that the lifting pin can be smoothly inserted and removed. It has the advantages of convenient operation and saving time and effort.

[0004] The technical solution of this utility model is as follows: An improved multi-functional unit anode guide rod lifting device, comprising: Connecting base for detachable connection with the boom support of the multi-functional unit; The lifting device body is connected to the connecting seat at the top and has two coaxial lifting device pin holes at the bottom. The lifting device body has a guide rod cavity with an opening at the bottom for the upper end of the anode guide rod to be inserted. The lifting pin can be detachably inserted into two lifting tool pin holes; The hydraulic cylinder has its axis parallel to the axis of the lifting pin hole, and includes a cylinder body and a piston rod. The cylinder body is fixedly installed on the lifting body, and the front end of the piston rod is connected to one end of the lifting pin through a connecting rod. The guide rod mechanism, with its axis parallel to the axis of the hydraulic cylinder, includes a guide sleeve and a guide rod that are in a sliding fit. The guide sleeve is fixedly installed on the main body of the lifting device, and one end of the guide rod is detachably and fixedly connected to the connecting rod to guide the connecting rod. There are two sets of guide wheel assemblies, which are respectively set at the two lifting pin holes. Each set includes at least two guide wheels that are evenly distributed around the circumference of the lifting pin holes. The outer circumferential surface of the guide wheel is in a guiding rolling engagement with the outer circumferential surface of the lifting pin. The rotating shaft of the guide wheel is rotatably mounted on the lifting body.

[0005] The beneficial effects of this technical solution are as follows: When using an improved anode guide rod lifting device for a multi-functional unit, the entire lifting device can be detachably fixed to the boom support of the multi-functional unit via a connecting seat, allowing it to move with the multi-functional unit and perform lifting operations. When lifting the anode guide rod, the multi-functional unit is moved until the lifting device body is directly above the anode guide rod. After precise alignment, the lifting device body is controlled to descend until the upper end of the anode guide rod extends into the guide rod cavity. Adjustments are made to ensure that the lifting device pin hole and the guide rod pin hole on the anode guide rod are as coaxial as possible. In its initial state, the piston rod of the hydraulic cylinder is in... In the extended state, the lifting pin is positioned outside the pin hole of the spreader via a connecting rod. Then, the hydraulic cylinder is activated, causing the piston rod to retract. This retraction, via the connecting rod, moves the lifting pin towards the pin hole. During this process, guided by the guide rod mechanism, the lifting pin moves precisely along its axis. The outer circumference of the guide wheel assembly engages with the outer circumference of the lifting pin, facilitating its positioning and further improving its accuracy. More importantly, this creates rolling friction between the lifting pin and the spreader body, significantly reducing friction and preventing jamming. Therefore, the technical solution of this application offers advantages such as convenient and quick operation, accurate and reliable positioning, low friction, reduced risk of jamming, and a much greater force required to install and remove the lifting pin than manual labor.

[0006] Based on the above solution, a further improvement is made as follows: the outer circumferential surface of the guide wheel has an annular groove, the cross-sectional shape of which is arc-shaped, V-shaped, or U-shaped. This design allows for precise positioning of the locating pin using the annular groove of the guide wheel.

[0007] Based on the above solution, the following improvements are made: a first detection module is installed on the main body of the lifting device to detect the axial position of the lifting pin. This first detection module enables precise detection and control of the lifting pin's position, especially during the insertion of the lifting pin, ensuring it is positioned precisely in the center of the lifting device, thus preventing force deviation during lifting.

[0008] Based on the above solution, a further improvement is made as follows: the main body of the lifting device is equipped with a second detection module for detecting the axial position of the anode guide rod within the guide rod cavity. This second detection module allows the anode guide rod to be positioned axially in a suitable location when inserted into the guide rod cavity, thereby ensuring that the lifting device pin hole and the guide rod pin hole are as coaxial as possible, facilitating the insertion and lifting of the pin.

[0009] Based on the above solution, the following further improvement is made: at least one end of the lifting pin has a conical head. This facilitates the insertion of the lifting pin, and the guiding effect of the conical head can compensate for errors.

[0010] Based on the above scheme, the following improvements are made: the axes of the lifting pin hole, hydraulic cylinder and guide rod mechanism are located in the same vertical plane; the lifting pin hole and guide rod are located on the upper and lower sides of the hydraulic cylinder, respectively; the middle part of the connecting rod is connected to the piston rod; and the two ends of the connecting rod are connected to the guide rod and the lifting pin, respectively.

[0011] Based on the above scheme, the following further improvement is made: one end of both the piston rod and the lifting pin is hinged to the connecting rod via a hinge shaft. This can compensate for positional errors.

[0012] Based on the above scheme, the following improvements are made: the first detection module includes two limit switches, which are respectively set at the two lifting pin holes so as to cooperate with the two ends of the lifting pin. Attached Figure Description

[0017] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0018] A specific embodiment of an improved multi-functional anode guide rod lifting device for a generator unit according to this utility model is as follows: Figure 1-3 As shown, an improved multi-functional anode guide rod lifting device for generator sets mainly includes a connecting seat 2, a lifting body 3, a lifting pin 4, a hydraulic cylinder 5, a guide rod mechanism 7, a guide wheel group 8, a first detection module, a second detection module, and a controller.

[0019] The connecting seat 2 is used to detachably connect with the boom support of the multi-functional unit, specifically by bolting it through multiple evenly distributed bolt holes 21.

[0020] The upper part of the lifting device body 3 is connected to the connecting seat 2, and the lower part has a main body bell jar 31. Two coaxial lifting device pin holes 32 are symmetrically arranged on the main body bell jar 31. The lifting device body 3 has a guide rod cavity 311 with an opening at the lower end, that is, the lower cavity of the main body bell jar 31, for the upper end of the anode guide rod 1 to be inserted. The lifting device body 3 is provided with a first detection module for detecting the axial position of the lifting pin 4, namely the first limit switch 91 and the second limit switch 92 in this embodiment. The setting of the first detection module can realize the accurate detection and control of the position of the lifting pin 4. Especially when the lifting pin 4 is inserted, it can control the lifting pin 4 to be exactly in the middle position of the lifting device body 3, so as to avoid the force deviation during lifting. The first detection module includes two limit switches 91 and 92, which are respectively set at the two lifting device pin holes 32 so as to cooperate with the two ends of the lifting pin 4.

[0021] like Figure 1 , 3 As shown, the lifting pin 4 is detachably inserted into two lifting pin holes 32, including a cylindrical part of the main body, a conical head 42 at one end, and a hinge hole 41 at the other end. At least one end of the lifting pin 4 has a conical head 42. This facilitates the insertion of the lifting pin 4, and the guiding effect of the conical head 42 helps to compensate for errors.

[0022] The axis of the hydraulic cylinder 5 is parallel to the axis of the lifting pin hole 32. It includes a cylinder body 51 and a piston rod 52. The cylinder body 51 is fixedly installed on the lifting body 3. The front end of the piston rod 52 is connected to one end of the lifting pin 4 through a connecting rod 6.

[0023] The guide rod mechanism 7 has its axis parallel to the axis of the hydraulic cylinder 5. It includes a guide sleeve 71 and a guide rod 72 with a sliding fit. The guide sleeve 71 is fixedly mounted on the lifting device body 3. One end of the guide rod 72 is detachably and fixedly connected to the connecting rod 6 to guide the connecting rod. The axes of the lifting device pin hole 32, the hydraulic cylinder 5, and the guide rod mechanism 7 are located in the same vertical plane. The lifting device pin hole 32 and the guide rod are located on the upper and lower sides of the hydraulic cylinder 5, respectively. The middle part of the connecting rod 6 is connected to the piston rod 52, and both ends of the connecting rod 6 are connected to the guide rod 72 and the lifting pin 4, respectively. One end of both the piston rod 52 and the lifting pin 4 is hinged to the connecting rod 6 via a hinge shaft 10. This can compensate for positional errors.

[0024] Two sets of guide wheel assemblies 8 are respectively installed at the two lifting pin holes 32, including at least two guide wheels 81 evenly distributed circumferentially along the lifting pin holes 32. The outer circumferential surface of the guide wheel 81 is in a guiding rolling engagement with the outer circumferential surface of the lifting pin 4, and the rotating shaft of the guide wheel 81 is rotatably mounted on the lifting body 3. The outer circumferential surface of the guide wheel 81 has an annular groove 811, and the cross-sectional shape of the annular groove 811 is arc-shaped, V-shaped, or U-shaped. This arrangement allows for precise positioning of the positioning pin using the annular groove 811 of the guide wheel 81. For the specific structure of this embodiment, see [link to specific embodiment]. Figure 2 As shown, each set of guide wheel assembly 8 includes four guide wheels 81, and the cross-sectional shape of the annular groove 811 of the guide wheel 81 is arc-shaped.

[0025] The lifting device body 3 is equipped with a second detection module for detecting the axial position of the anode guide rod 1 within the guide rod cavity 311, which is the third limit switch 93 in this embodiment. The second detection module allows the anode guide rod 1 to be positioned axially in a suitable position when inserted into the guide rod cavity 311, thereby ensuring that the lifting device pin hole 32 and the guide rod pin hole 11 are as coaxial as possible, so as to facilitate the insertion and lifting of the pin 4.

[0026] In use, the entire lifting device can be detachably fixed to the boom support of the multi-functional unit via the connecting seat 2, so as to move with the multi-functional unit to realize the lifting work. When it is necessary to lift the anode guide rod 1, control the multi-functional unit to move until the lifting body 3 is directly above the anode guide rod 1. After precise alignment, control the lifting body 3 to descend until the upper end of the anode guide rod 1 extends into the guide rod cavity 311. Adjust the lifting pin hole 32 to be as coaxial as possible with the guide rod pin hole 11 on the anode guide rod 1. In the original state, the piston rod 52 of the hydraulic cylinder 5 is in the extended state, so as to drive the lifting pin 4 through the connecting rod 6. Located outside the area of ​​the lifting pin hole 32, the hydraulic cylinder 5 is then activated, causing the piston rod 52 to retract. This retraction, via the connecting rod 6, moves the lifting pin 4 towards the lifting pin hole 32. During this process, guided by the guide rod mechanism 7, the lifting pin 4 can move precisely along its axis. The outer circumferential surface of the guide wheel 81 of the guide wheel assembly 8 engages with the outer circumferential surface of the lifting pin 4, facilitating its positioning and further improving its accuracy. More importantly, this creates rolling friction between the lifting pin 4 and the lifting body 3, significantly reducing friction and preventing jamming. Therefore, the technical solution of this application offers advantages such as convenient and quick operation, accurate and reliable positioning, low friction, reduced risk of jamming, and a much greater force required to install and remove the lifting pin 4 than manual labor.

[0027] The main body 3 of the lifting device and the connecting seat 2, after being connected to the multi-functional unit, play a major load-bearing role, supporting the main weight of the anode guide rod 1. The hydraulic cylinder 5 is powered by the hydraulic station of the multi-functional unit.

The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
