Description

Technical Field

[0001] The invention relates to the technical field of nonferrous metallurgy aluminum electrolysis, and in particular to a quick suspension fixing mechanism for a terminal operating tool of a multifunctional overhead crane for aluminum electrolysis. Background Art

[0002] The electrolytic aluminum multifunctional overhead crane is installed in the electrolytic aluminum workshop to process the electrolytic aluminum anode guide rods during the aluminum electrolysis production process. The overhead crane needs to meet the functions of breaking the shell of the anode guide rod surface covering material by knocking and breaking, replacing the anode by twisting and pulling the damaged anode guide rod, and removing the slag in the electrolytic cell. These three functions require three different end working devices.

[0003] The existing multifunctional overhead crane has a tool rotating device on the trolley of the overhead crane, and then three power drive units with independent lifting functions are installed on the tool rotating device, and different terminal working tools are installed at the end of each power drive unit. Considering that the three power drive units with independent lifting functions of the three terminal working tools occupy a large space, have a large and complicated structure, and are not conducive to overall motion control, it is possible to consider using a common lifting power drive unit to achieve the operation by replacing different terminal working tools. In order to solve the problem of replacing different terminal working tools, the present invention designs a quick fixing and clamping mechanism between the terminal working tool and the fixed frame, which can adaptively position and reliably fix the replaced terminal working tool. Summary of the invention

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a quick hanging and fixing mechanism for the terminal working tool of the aluminum electrolysis multifunctional overhead crane, which can quickly fix and clamp the terminal working tool and the fixing frame, can adaptively position, and can reliably fix the replaced terminal working tool.

[0005] The technical solution of the present invention is: a quick suspension fixing mechanism for an aluminum electrolysis multifunctional overhead crane end working tool comprises: a fixing frame (1), a T-shaped frame (2), a conical head (3), a conical sleeve (4), a U-shaped clamping plate (5), and a clamping oil cylinder (6);

[0006] Each T-shaped frame includes a left horizontal arm, a right horizontal arm, and a vertical arm. The left horizontal arm has a conical head, and the fixed frame has a conical sleeve matching the conical head. A clamping cylinder is horizontally installed on the side of the conical sleeve. The lower end of the vertical arm is connected to an end operating tool.

[0007] The public lifting mechanism drives the T-frame to rise to the corresponding fixed position of the fixed frame, and then moves horizontally to drive the T-frame close to the fixed frame. When the conical head of the T-frame and the conical sleeve of the fixed frame are aligned, the public lifting mechanism drives the T-frame to descend until the conical head and the conical sleeve are completely fixed. The clamping cylinder drives the U-shaped clamping plate to extend into the conical sleeve to clamp the conical head.

[0008] Each T-frame of the present invention comprises a left horizontal arm, a right horizontal arm and a vertical arm, wherein the left horizontal arm has a conical head, the fixing frame has a conical sleeve matching the conical head, a clamping cylinder is horizontally installed on the side of the conical sleeve, and a terminal working tool is connected to the lower end of the vertical arm; the common lifting mechanism drives the T-frame to rise to the corresponding fixed position of the fixing frame, and then moves horizontally to drive the T-frame close to the fixing frame, and when the conical head of the T-frame and the conical sleeve of the fixing frame are aligned, the common lifting mechanism drives the T-frame to descend, until the conical head and the conical sleeve are completely fixed, and the clamping cylinder drives the U-shaped clamping plate to extend into the conical sleeve to clamp the conical head; therefore, the terminal working tool and the fixing frame can be quickly fixed and clamped, positioning can be adaptive, and the replaced terminal working tool can be reliably fixed.

[0015] like Figure 1-4 As shown, the quick suspension fixing mechanism of the aluminum electrolysis multifunctional overhead crane end working tool comprises: a fixing frame 1, a T-shaped frame 2, a conical head 3, a conical sleeve 4, a U-shaped clamping plate 5, and a clamping cylinder 6;

[0016] Each T-shaped frame includes a left horizontal arm, a right horizontal arm, and a vertical arm. The left horizontal arm has a conical head, and the fixed frame has a conical sleeve matching the conical head. A clamping cylinder is horizontally installed on the side of the conical sleeve. The lower end of the vertical arm is connected to an end operating tool.

[0017] The public lifting mechanism drives the T-frame to rise to the corresponding fixed position of the fixed frame, and then moves horizontally to drive the T-frame close to the fixed frame. When the conical head of the T-frame and the conical sleeve of the fixed frame are aligned, the public lifting mechanism drives the T-frame to descend until the conical head and the conical sleeve are completely fixed. The clamping cylinder drives the U-shaped clamping plate to extend into the conical sleeve to clamp the conical head.

[0018] Each T-frame of the present invention comprises a left horizontal arm, a right horizontal arm and a vertical arm, wherein the left horizontal arm has a conical head, the fixing frame has a conical sleeve matching the conical head, a clamping cylinder is horizontally installed on the side of the conical sleeve, and a terminal working tool is connected to the lower end of the vertical arm; the common lifting mechanism drives the T-frame to rise to the corresponding fixed position of the fixing frame, and then moves horizontally to drive the T-frame close to the fixing frame, and when the conical head of the T-frame and the conical sleeve of the fixing frame are aligned, the common lifting mechanism drives the T-frame to descend, until the conical head and the conical sleeve are completely fixed, and the clamping cylinder drives the U-shaped clamping plate to extend into the conical sleeve to clamp the conical head; therefore, the terminal working tool and the fixing frame can be quickly fixed and clamped, positioning can be adaptive, and the replaced terminal working tool can be reliably fixed.

[0019] Preferably, the conical head is processed with a fixing ring groove at the position of the U-shaped clamping plate, and the U-shaped clamping plate extends into the fixing ring groove of the conical head 3. Clamp the conical head, and the upper end of the T-shaped frame is fixed.

[0020] Preferably, if Figure 2 As shown, the right cross arm of the T-frame is provided with a collision buffer device below. In this way, when the conical head of the left cross arm hits the conical sleeve, the left cross arm will not move upward due to the contact, thereby avoiding the imbalance between the left cross arm and the right cross arm.

[0021] Preferably, the fixing frame further comprises: a locking oil cylinder 7, an oil cylinder joint 8, and a locking claw 9. The locking oil cylinder pushes the rear end of the locking claw through the oil cylinder joint, and then the locking claw rotates and extends into the corresponding hole on the T-frame, thereby locking the T-frame. In this way, the T-frame is reliably fixed to the fixing frame.

[0022] Preferably, the cross-section of the locking claw is a trapezoidal structure, and the corresponding hole on the T-frame is a trapezoidal hole. When the locking claw rotates, it hooks the corresponding trapezoidal hole on the T-frame to limit the left-right and front-back swinging of the T-frame.

[0023] The working principle of the present invention is as follows:

[0024] The public lifting mechanism drives the T-frame and the end-operating tool installed at the lower end to rise to the position of the fixed frame to suspend the T-frame, and then suspend and fix it. The specific suspension and fixing process is as follows: the public lifting mechanism drives the T-frame to rise to the corresponding fixed position of the fixed frame, and then moves horizontally to drive the T-frame close to the fixed frame. After the conical head of the T-frame and the conical sleeve of the fixed frame are aligned, the lifting mechanism drives the T-frame to descend until the conical head and the conical sleeve are completely fixed. The clamping cylinder installed horizontally on the side of the conical sleeve drives the U-shaped clamping plate to extend into the conical sleeve. The conical head is processed with a fixed ring groove at the position of the U-shaped clamping plate. The U-shaped clamping plate just extends into the ring groove of the conical head and clamps the conical head. In this way, the upper end of the T-frame is fixed.

[0025] In order to prevent the T-frame from shaking after being fixed, a locking device is installed at the lower end of the fixing frame. When the T-frame is fixed, the locking cylinder pushes the rear end of the locking claw through the cylinder joint, and then the locking claw rotates and automatically extends into the corresponding trapezoidal hole on the T-frame, automatically locking the T-frame and completing the locking action. In this way, the T-frame is reliably fixed to the fixing frame.

[0026] When the T-frame and the end-use tools installed on it need to be replaced, just follow the above-mentioned operation sequence in reverse order, that is, first open the locking claw, then retract the U-shaped pallet, and then lift the T-frame to a certain height, and the T-frame can be separated from the fixed frame.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the protection scope of the technical solution of the present invention.
