Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cell flue, in particular to a mobile crust breaker. Background Art

[0002] During the production process of electrolytic aluminum, the phenomenon of crust formation on the flue is a common technical problem, mainly including design defects, thermal expansion during the roasting stage, lining expansion extrusion, etc. Therefore, during the electrolytic production process, it is necessary to remove the crust at the crust formation of the flue.

[0003] The conventional treatment method is that the operator uses a hammer and a pneumatic pick to operate close to the crust formation of the flue. The operating electrolytic cell will have an impact on the operator in terms of high temperature, high heat and strong magnetic field, which is likely to cause burns to the operator. At the same time, the operating space at the local part is limited, there are safety risks. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a mobile crust breaker to solve the problems of limited operating space at the local part and safety risks when the operator uses a hammer and a pneumatic pick to operate close to the crust formation of the flue.

[0005] To achieve the above purpose, the basic scheme of the utility model is as follows: The mobile crust breaker includes a frame, supporting wheels and a rotating shaft. The supporting wheels are fixedly installed at the ends of the rotating shaft, and the rotating shaft is rotatably installed in the middle of the frame. It also includes:

[0006] An installation part for fixedly installing the pneumatic pick, and the installation part is installed at one end of the frame;

[0007] A rotating part for horizontally rotating the pneumatic pick, and the rotating part is installed between the installation part and the frame;

[0008] A control part for controlling the horizontal rotation angle of the rotating part, and the control part is installed at one end of the frame far from the installation part.

[0009] The technical principle of the present utility model is as follows: When using a mobile crust breaker for crust breaking, first fix the pneumatic pick to the installation part. Hold the side of the frame where the control part is set by hand, and push the entire mobile crust breaker to move to the corresponding flue. When it is found that the corresponding flue needs crust breaking treatment, start the pneumatic pick. The entire mobile crust breaker can be remotely pushed to make the pneumatic pick approach the place to be crust broken for crust breaking treatment. At this time, the end of the frame away from the installation part can be pressed down or lifted up, and the frame rotates at the rotation axis, so that the frame drives the installation part and the pneumatic pick to move vertically synchronously, and the vertical position of the pneumatic pick can be adjusted to be opposite to the place to be crust broken of the flue. At the same time, the horizontal position of the pneumatic pick can be controlled through the control part, and the adjustment of the horizontal and vertical positions of the pneumatic pick can be combined, so that the crust breaking operation of the pneumatic pick in a narrow area such as the flue can be flexibly controlled. At the same time, the operator can complete the adjustment operation at the left end of the frame, which is safer and simpler, and reduces the risks faced by the crust breaking operation.

[0010] Furthermore, the installation part includes:

[0011] A fixed cylinder that can be fixedly connected to the pneumatic pick. The fixed cylinder is horizontally arranged, and the side wall of the fixed cylinder is fixedly connected to the rotating part;

[0012] A support platform that can fixedly support the pneumatic pick. The upper surface of the support platform is horizontally arranged, and the support platform is fixedly installed on the side wall of the fixed cylinder away from the rotating part.

[0013] Through the above settings, the fixed cylinder and the support platform can stably supply the pneumatic pick for installation and support, so that the pneumatic pick can be installed more stably and perform crust breaking treatment stably.

[0014] Furthermore, the rotating part includes:

[0015] A ball bearing. The axis of the ball bearing is perpendicular to the axis of the fixed cylinder. The inner ring of the ball bearing is fixedly connected to the frame, the outer ring of the ball bearing is fixedly connected to the outer wall of the fixed cylinder, and the outer ring of the ball bearing is connected to the control part.

[0016] Through the above settings, the ball bearing can support the fixed cylinder, the support platform and the pneumatic pick. At the same time, through the rotation of the inner ring and the outer ring of the ball bearing, the fixed cylinder, the support platform and the pneumatic pick can be controlled to rotate around the ball bearing, so that the rotation of the pneumatic pick in the horizontal direction can also be stably adjusted.

[0017] Furthermore, the control part includes:

[0018] A first cable. One end of the first cable is fixed to the outer wall of the ball bearing after winding around the outer ring of the ball bearing for half a turn or more, and the other end of the first cable is connected to the end of the frame away from the installation part;

[0019] The second cable, one end of the second cable is fixedly connected to the outer wall of the ball bearing after winding around the outer ring of the ball bearing for half a turn or more, the other end of the second cable is connected to the end of the frame away from the installation part, and the first cable and the second cable are wound around the outer ring of the ball bearing in opposite directions.

[0020] With the above arrangement, since the first cable and the second cable are wound around the outer ring of the ball bearing in opposite directions, when the first cable or the second cable is tightened, the outer ring of the ball bearing can be driven to rotate relative to the inner ring in opposite directions, and then the fixed cylinder, the support platform and the pneumatic pick can be controlled to rotate forward or backward around the inner ring of the ball bearing, and the horizontal rotation direction of the pneumatic pick can be remotely controlled.

[0021] Furthermore, the control part further includes:

[0022] The first handle, the first handle is fixedly installed on the end of the frame away from the installation part;

[0023] The first pull handle hinged to the first handle, one end of the first pull handle away from the first handle is fixedly connected to the end of the first cable. When the first pull handle rotates relative to the first handle, the first pull handle can pull the end of the first cable to move away from the ball bearing;

[0024] The second handle, the second handle is fixedly installed on the end of the frame away from the installation part;

[0025] The second pull handle hinged to the second handle, one end of the second pull handle away from the second handle is fixedly connected to the end of the second cable. When the second pull handle rotates relative to the second handle, the second pull handle can pull the end of the second cable to move away from the ball bearing.

[0026] With the above arrangement, when pushing the entire mobile crust breaker to move horizontally, the operator can apply force better at the first handle and the second handle. At the same time, when controlling the horizontal rotation direction of the pneumatic pick, the tightening state of the first cable and the second cable can be controlled through the first pull handle and the second pull handle, making the control of the horizontal rotation direction of the pneumatic pick more labor-saving and reliable.

[0027] Furthermore, the end of the first cable passes through the first handle and is connected to the first pull handle, and the end of the second cable passes through the second handle and is connected to the second pull handle.

[0028] With the above arrangement, the first handle can control the tightening path of the first cable, and the second handle can control the tightening path of the second cable, making the control of the first cable and the second cable more stable.

[0029] Furthermore, a first baffle is fixedly installed on one end of the first pull handle away from the first handle, and a second baffle is fixedly installed on one end of the second pull handle away from the second handle.

[0030] With the above settings, the first baffle and the second baffle are convenient for limiting the operator's hand, making it easier to apply force when tightening the first cable and the second cable. Description of the Drawings

Detailed Embodiment

[0033] The technical solutions in the embodiments of the present invention will be further described below with reference to the drawings and embodiments.

[0034] This embodiment is basically as Figure 1 shown. An embodiment of the present invention provides a mobile crust breaker, which includes a frame 10, support wheels 101, a rotating shaft 102, a mounting portion for fixedly installing a pneumatic pick, a rotating portion for horizontally rotating the pneumatic pick, and a control portion for controlling the horizontal rotation angle of the rotating portion, as Figure 1 shown. The left end of the frame 10 is inclined downward, and the right end of the frame 10 is horizontally arranged; two support wheels 101 are coaxially and fixedly installed at both ends of the rotating shaft 102, and the rotating shaft 102 is rotatably installed at the middle of the right end of the frame 10; the mounting portion is installed on the right end of the frame 10, the rotating portion is installed between the mounting portion and the frame 10, and the control portion is installed on the left end of the frame 10.

[0035] At the same time, as Figure 1 shown, the mounting portion includes a fixed cylinder 20 that can be fixedly connected to the pneumatic pick and a support platform 201 that can fixedly support the pneumatic pick. The fixed cylinder 20 is horizontally arranged, the upper surface of the support platform 201 is horizontally arranged, and the support platform 201 is welded to the side wall of the fixed cylinder 20 away from the rotating frame 10.

[0036] As Figure 1 shown, the rotating portion includes a ball bearing 30. The axis of the ball bearing 30 is perpendicular to the axis of the fixed cylinder 20, and the inner ring of the ball bearing 30 is welded to the frame 10, and the outer ring of the ball bearing 30 is welded to the outer wall of the fixed cylinder 20.

[0037] As Figure 1As shown in the figure, the control unit includes a first cable 401, a second cable 402, a first handle 403, a first pull handle 404 hinged to the first handle 403, a second handle 405, and a second pull handle 406 hinged to the second handle 405. The first handle 403 is welded to the left end of the frame 10, and the second handle 405 is welded to the left end of the frame 10. One end of the first cable 401 winds around the outer ring of the ball bearing 30 for half a turn and then is fixedly connected to the outer wall of the ball bearing 30. The other end of the first cable 401 passes through the right end of the first handle 403 and is welded to the right side of the lower end of the first pull handle 404. One end of the second cable 402 winds around the outer ring of the ball bearing 30 for more than half a turn and then is fixedly connected to the outer wall of the ball bearing 30. The other end of the second cable 402 passes through the right end of the second handle 405 and is welded to the right side of the lower end of the second pull handle 406. At the same time, the first cable 401 and the second cable 402 are wound around the outer ring of the ball bearing 30 in opposite directions. When the first pull handle 404 rotates relative to the first handle 403, the first pull handle 404 can pull the end of the first cable 401 to move away from the ball bearing 30. When the second pull handle 406 rotates relative to the second handle 405, the second pull handle 406 can pull the end of the second cable 402 to move away from the ball bearing 30.

[0038] In addition, as Figure 1 shown, a first baffle 407 is integrally formed at one end of the first pull handle 404 away from the first handle 403, and a second baffle 408 is integrally formed at one end of the second pull handle 406 away from the second handle 405.

[0039] Before the mobile crust breaker in this embodiment is used, the pneumatic pick is first installed on the support table 201 or the fixed cylinder 20 with bolts. During use, the operator holds the first handle 403 and the second handle 405 of the mobile crust breaker and pushes the entire mobile crust breaker to move to the corresponding flue. When it is found that the corresponding flue needs to be crust broken, the pneumatic pick is started. At the same time, the first handle 403 and the second handle 405 are held again to push the pneumatic pick to be directly opposite to the part of the flue to be crust broken. At this time, the left end of the frame 10 can be pressed down or lifted through the first handle 403 and the second handle 405. At this time, the right end of the frame 10 rotates around the rotating shaft 102, so that the right end of the frame 10 drives the fixed cylinder 20, the support table 201 and the pneumatic pick to have a vertical displacement synchronously, and the vertical position of the pneumatic pick can be adjusted to be opposite to the part of the flue to be crust broken.

[0040] Meanwhile, the four fingers of the operator's two hands can be held on the first pull handle 404 and the second pull handle 406. At this time, when the left hand tightens the first pull handle 404 close to the first handle 403, the first pull handle 404 tightens the first cable 401, and the right end of the first cable 401 drives the outer ring of the ball bearing 30 to rotate forward, so that the outer ring of the ball bearing 30 drives the fixed cylinder 20, the support platform 201 and the pneumatic pick to rotate towards the upper left side; conversely, when the right hand tightens the second pull handle 406 close to the second handle 405, the second pull handle 406 tightens the second cable 402, and the right end of the second cable 402 drives the outer ring of the ball bearing 30 to rotate reversely, so that the outer ring of the ball bearing 30 drives the fixed cylinder 20, the support platform 201 and the pneumatic pick to rotate towards the lower right side, making the pneumatic pick rotate in the horizontal direction, and enabling the position of the pneumatic pick in the horizontal direction to be adjusted relative to the shell-breaking area to be processed of the flue.

[0041] The above adjustments of the position of the pneumatic pick in the horizontal and vertical directions can be combined, which can flexibly control the shell-breaking operation of the pneumatic pick in a narrow area such as the flue. At the same time, the operator can complete the adjustment operation at the left end of the frame 10, which is safer and simpler, and reduces the risks faced by the shell-breaking operation.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
