Description

Technical Field

[0001] The utility model relates to the technical field of busbar lifting frames, in particular to a lower frame of a busbar lifting frame. Background Art

[0002] During the electrolytic aluminum production process, the anode carbon blocks will be continuously consumed, and the height of the anode guide rods connected to the anode carbon blocks will move down along with the busbar. This operation is completed by the busbar lifting frame. When the busbar moves to the process downline position, the busbar lifting device is required to clamp and fix the anode guide rods, and then the anode lifting mechanism is used to lift the busbar to the process upline. When adjusting the relative position of the anode guide rods on the busbar, firstly, the corresponding anode guide rods are clamped by several groups of anode guide rod clamp mechanisms on the lower frame of the busbar lifting device to prevent the anode carbon blocks from falling.

[0003] The anode clamp of the lower frame of the existing busbar lifting frame pushes the cylinder piston rod upward through a spring, and the piston rod pushes the anode guide rod clamp to rotate counterclockwise around the pin shaft, so that the anode guide rod clamp is tightened upward to clamp the anode guide rod. The gap between the opening of the anode clamp and the anode guide rod is too small, and the anode guide rod cannot be quickly inserted into the anode guide rod clamp.

[0004] An existing embracing side-clamping anode clamp includes an upper frame and a lower frame, and only one spring cylinder is installed on the lower frame, and the spring cylinder is connected to the second clamping strip through the fifth connecting rod group, the second pull rod and the sixth connecting rod assembly. When the upper frame cylinder of the anode clamp is ventilated, the embracing spring is compressed by the upper frame cylinder, and the lower frame is opened to a certain angle through the second pull rod, and the anode clamps on both sides of the lifting frame are opened in an eight-shaped shape; when the upper frame cylinder is de-energized, the lower frame falls down and closes. The sixth connecting rod assembly of the anode clamp needs to withstand a large force when clamping the anode, making the sixth connecting rod assembly easy to be damaged. Utility Model Content

[0005] The first purpose of the utility model is to provide a lower frame of a busbar lifting frame which can reduce the stress on components.

[0006] In order to achieve the above-mentioned first purpose, the lower frame of the busbar lifting frame provided by the utility model includes: a frame body, a support plate is fixed to the frame body, a third elastic component and a piston cylinder are installed on the support plate, and the piston cylinder is arranged above the third elastic component; the piston rod of the piston cylinder passes through the third elastic component and is connected to the first balance beam, the first balance beam is connected to the first end of the pull rod, and the second end of the pull rod is connected to the second balance beam; the two ends of the second balance beam are respectively provided with a first connecting mechanism and a second connecting mechanism, the first connecting mechanism is connected to the first rocker arm, and the second connecting mechanism is connected to the second rocker arm; along the symmetry plane of the lower frame, the first connecting mechanism is located on the first side of the lower frame, and the second connecting mechanism is located on the second side of the lower frame. The connecting mechanism is located on the second side of the lower frame, the first rotating shaft connected to the first rocker arm is located on the second side of the lower frame, the second rotating shaft connected to the second rocker arm is located on the first side of the lower frame, the first rotating shaft is sleeved with a first eccentric connecting piece, the second rotating shaft is sleeved with a second eccentric connecting piece, the first eccentric connecting piece is connected to the first clamping body, the second eccentric connecting piece is connected to the second clamping body, and a clamping opening is formed between the first clamping body and the second clamping body; the first clamping body is connected to the first end of the first elastic component, the second end of the first elastic component is connected to the first rotating shaft, the second clamping body is connected to the first end of the second elastic component, and the second end of the second elastic component is connected to the second rotating shaft.

[0007] It can be seen from the above scheme that when the piston cylinder is inflated, the air pressure can push the piston rod to extend downward, thereby driving the pull rod to move downward. When the pull rod moves downward, the first rocker arm and the second rocker arm swing downward, thereby driving the first rotating shaft and the second rotating shaft to rotate, thereby driving the first eccentric connecting member and the second eccentric connecting member to rotate, thereby driving the first clamping body and the second clamping body to move outward, so that the clamping mouth is opened. When the piston cylinder is deflated, the third elastic component pushes the piston rod back upward, and the piston rod drives the pull rod to move upward, so that the first rocker arm and the second rocker arm swing upward, thereby driving the first rotating shaft and the second rotating shaft to rotate, driving the first eccentric connecting member and the second eccentric connecting member to rotate, thereby driving the first clamping body and the second clamping body to move inward, so that the clamping mouth is narrowed. Since the first elastic component is connected to the first clamping body, and the second elastic component is connected to the second clamping body, the clamping surface on the first clamping body and the clamping surface of the second clamping body remain vertical. Since the first rocker arm is connected to the first connecting mechanism located on the first side of the lower frame and is connected to the first rotating shaft located on the second side of the lower frame, and the second rocker arm is connected to the second connecting mechanism located on the second side of the lower frame and is connected to the second rotating shaft located on the first side of the lower frame, this connection method can extend the length of the first rocker arm and the second rocker arm, thereby reducing the force on the first rocker arm and the second rocker arm, so that the first rocker arm and the second rocker arm will not be damaged due to excessive force, thereby extending the service life of the first rocker arm and the second rocker arm.

[0008] In a further solution, the number of the third elastic component and the number of the piston cylinder are both two, and the third elastic component and the piston cylinder are arranged at both ends of the support plate.

[0009] It can be seen that the two piston cylinders and the two third elastic components can adjust the downward movement position of the pull rod, thereby adjusting the position of the clamping port.

[0010] In a further solution, a pressure plate is provided between the third elastic component and the piston cylinder, the pressure plate is connected to the first end of the piston rod, and the second end of the piston rod is connected to the second balance beam.

[0011] It can be seen that when the piston rod moves downward, the third elastic component can be compressed through the pressure plate.

[0012] In a further solution, a piston rod is connected to the first end and the second end of the first balance beam, and the middle part of the first balance beam is connected to the first end of the pull rod.

[0013] It can be seen that both ends of the first balance beam are connected to the piston rod, and the first balance beam can balance the forces applied by the two piston cylinders.

[0014] In a further solution, a first elongated hole is provided at the first end of the first rocker arm, and a first square hole is provided at the second end of the first rocker arm; the first elongated hole is connected to the first connecting mechanism, and the first square hole is connected to the first rotating shaft.

[0015] In a further solution, a second elongated hole is provided at the first end of the second rocker arm, and a second square hole is provided at the second end of the second rocker arm; the second elongated hole is connected to the second connecting mechanism, and the second square hole is connected to the second rotating shaft.

[0016] It can be seen that the long hole can prevent the rocker arm from being stuck by the connecting part of the connecting mechanism when it swings downward or upward, and the square hole can drive the rotating shaft to rotate.

[0017] In a further solution, the first clamping body is provided with a first clamping surface, and the first clamping surface is arranged along the vertical direction; the second clamping body is provided with a second clamping surface, and the second clamping surface is arranged along the vertical direction.

[0018] It can be seen that the first clamping surface and the second clamping surface are vertically arranged through the first elastic component and the second elastic component, so that the first clamping surface and the second clamping surface can better clamp the anode guide rod.

[0019] In a further solution, the first eccentric connecting member is connected to the first clamping body via a first pin shaft; and the second eccentric connecting member is connected to the second clamping body via a second pin shaft.

[0020] It can be seen that the clamping body is driven to move by the pin shaft, and the clamping body can move along the pin shaft.

[0027] See also Figure 1 and Figure 2 The lower frame of the busbar lifting frame of the utility model includes a frame body 1, a support plate 114 is fixed to the frame body 1, a third elastic component 112 and a piston cylinder 111 are mounted on the support plate, and the piston cylinder 111 is arranged above the third elastic component 112. The third elastic component is a spring, and the piston cylinder 111 is fixed to the frame body 1. A pressing plate 115 is arranged between the third elastic component 112 and the piston cylinder 111, and the pressing plate 115 is connected to the first end of the piston rod 113 of the piston cylinder 111, and the piston rod 113 of the piston cylinder 111 passes through the third elastic component 112 and the support plate 114 to be connected to the first balance beam 12, and the second end of the piston rod 113 is connected to the first balance beam 12.

[0028] When the piston cylinder 111 is inflated, the air pressure pushes the piston rod 113 to extend downward. Since the piston rod 113 is connected to the pressure plate 115, the piston rod 113 drives the pressure plate 115 to press downward. The third elastic component 112 is in contact with the pressure plate 115, and the third elastic component is in a compressed state. When the piston cylinder 111 is deflated, the third elastic component 112 pushes the piston rod 113 back upward. Further, the number of the piston cylinder 111 and the third elastic component 112 is two, and the piston cylinder 111 and the third elastic component 112 are arranged at both ends of the support plate. Further, since the number of the piston cylinder 111 is two, a piston rod 113 is connected to the first end and the second end of the first balance beam 12.

[0029] The middle part of the first balance beam 12 is connected to the first end of the pull rod 13, and the second end of the pull rod 13 is connected to the second balance beam 14. The first connecting mechanism 152 and the second connecting mechanism 151 are respectively provided at both ends of the second balance beam 12, the first connecting mechanism 152 is connected to the first rocker arm 161, and the second connecting mechanism 152 is connected to the second rocker arm 162.

[0030] See also Figure 3 Along the symmetry plane of the lower frame, the first connecting mechanism 152 is located on the first side of the lower frame, the second connecting mechanism 152 is located on the second side of the lower frame, the first rotating shaft 171 connected to the first rocker arm 161 is located on the second side of the lower frame, and the second rotating shaft 172 connected to the second rocker arm 162 is located on the first side of the lower frame.

[0031] Further, see Figure 4 , a first end of the first rocker arm 161 is provided with a long hole 164, and a second end of the rocker arm 161 is provided with a square hole 163. The long hole 164 is connected to the first connecting mechanism 152, and the square hole 163 is connected to the first rotating shaft 171. Further, the square hole 163 is a hexagonal hole. The long hole 164 can prevent the first rocker arm 161 from being stuck by the connecting part of the connecting mechanism 152 when swinging downward or upward, and the square hole 163 can drive the first rotating shaft 171 to rotate. Further, the first rotating shaft 171 is square and matches the square hole 163.

[0032] Similarly, a second elongated hole is disposed at the first end of the second rocker arm 162 , and a second square hole is disposed at the second end of the second rocker arm 162 ; the second elongated hole is connected to the second connecting mechanism 151 , and the second square hole is connected to the second rotating shaft 172 .

[0033] The first rotating shaft 171 is sleeved with a first eccentric connecting member 181, and the second rotating shaft 172 is sleeved with a second eccentric connecting member 182. The first eccentric connecting member 181 is connected to the first clamping body 201, and the second eccentric connecting member 182 is connected to the second clamping body 202. A clamping opening is formed between the first clamping body 201 and the second clamping body 202. The first eccentric connecting member 181 is connected to the first clamping body 201 through a first pin shaft 191; the second eccentric connecting member 182 is connected to the second clamping body 202 through a second pin shaft 192.

[0034] Further, two first eccentric connecting members 181 are provided, and the two first eccentric connecting members 181 are provided at both ends of the first clamping body 201 and connected by the first pin 191. Similarly, two second eccentric connecting members 182 are provided, and the two second eccentric connecting members 182 are provided at both ends of the second clamping body 202 and connected by the second pin 192. The first eccentric connecting member 181 and the second eccentric connecting member 182 can drive the first clamping body 201 and the second clamping body 202 to move inward or outward.

[0035] The first clamping body 201 and the second clamping body 202 form a clamping opening, the first clamping body 201 is connected to the first end of the first elastic component 211, the second end of the first elastic component 211 is connected to the first rotating shaft 171, the second clamping body 202 is connected to the first end of the second elastic component 212, and the second end of the second elastic component 212 is connected to the second rotating shaft 172. The first clamping body 201 is provided with a first clamping surface, and the first clamping surface is arranged in the vertical direction; the second clamping body 202 is provided with a second clamping surface, and the second clamping surface is arranged in the vertical direction.

Furthermore, the first clamping surface and the second clamping surface can be provided with patterns or other methods to increase the friction coefficient, so that the clamping body can better clamp the anode conductor.

[0037] When the piston cylinder 111 is inflated, the air pressure can push the piston rod 113 to extend downward, thereby driving the pull rod 13 to move downward. When the pull rod 13 moves downward, the first rocker arm 161 and the second rocker arm 162 swing downward, thereby driving the first rotating shaft 171 and the second rotating shaft 172 to rotate, thereby driving the first eccentric connecting member 181 and the second eccentric connecting member 182 to rotate, thereby driving the first clamping body 201 and the second clamping body 202 to move outward, so that the clamping port is opened, and the anode guide rod can be replaced at this time. When the piston cylinder is deflated, the third elastic component 112 pushes the piston rod 113 back upwards, and the piston rod 113 drives the pull rod 13 to move upwards, so that the first rocker arm 161 and the second rocker arm 162 swing upwards, thereby driving the first rotating shaft 171 and the second rotating shaft 172 to rotate, driving the first eccentric connecting member 181 and the second eccentric connecting member 182 to rotate, thereby driving the first clamping body 201 and the second clamping body 202 to move inwards, so that the clamping opening is narrowed, and the anode guide rod is clamped at this time. Since the first rocker arm 161 is connected to the first connecting mechanism 152 located on the first side of the lower frame and is connected to the first rotating shaft 171 located on the second side of the lower frame, and the second rocker arm 162 is connected to the second connecting mechanism 151 located on the second side of the lower frame and is connected to the second rotating shaft 172 located on the first side of the lower frame, this connection method can extend the length of the first rocker arm and the second rocker arm, thereby reducing the force on the first rocker arm and the second rocker arm, so that the first rocker arm and the second rocker arm will not be damaged due to excessive force, thereby extending the service life of the first rocker arm and the second rocker arm.
