Description

TECHNICAL FIELD

[0001] The utility model relates to metallurgical equipment field, concretely relates to a rail change device for anode copper plate transfer trolley. BACKGROUND

[0002] With the continuous progress of copper smelting processing technology, production efficiency is continuously improved, and the demand for anode copper plate transfer conveying technology is more and more vigorous. In the production process, the anode copper plate needs to be transported by the plate transfer trolley, and is transferred from the casting production area to the electrolysis production area. During the period, if the plate transfer trolley fails, it needs to be pushed into the maintenance table for maintenance. Because there is a long distance between the maintenance table and the transfer track, the existing rail changing technology is not applicable. For example, a rail trolley transmission system rail changer device is driven by a motor to rotate the screw rod installed at the bottom of the track, which realizes the translation of the trolley track, but it is not suitable for long distance movement. For another example, the commonly used turnout type rail changing device needs to manually push the trolley into the maintenance table from the turnout when the trolley power fails, which has high labor intensity and low efficiency. If the rail butt joint precision is insufficient, the general rail changing device will produce horizontal displacement or height difference, which will increase the impact and wear, and reduce the service life of the trolley walking assembly and the track. Therefore, it is necessary to design a fault plate transfer trolley rail changing device to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0003] In view of the above technical problems, the utility model provides a fault plate transfer trolley rail changing device to solve the problem that the existing rail changing technology cannot transfer the fault trolley to the maintenance table for a long distance, and the rail changing device has insufficient rail butt joint precision and rigidity.

[0004] To solve the above problems, the utility model adopts the following technical scheme to solve its technical problems:

[0005] The utility model provides a fault plate transfer trolley rail changing device, which is used for rail changing and transferring of the fault trolley between the plate transfer main track and the maintenance table. The plate transfer main track extends along the track direction, the maintenance table is placed parallel to the plate transfer main track, and a transverse translation track is laid in the direction perpendicular to the plate transfer main track and the maintenance table, and the plate transfer main track and the maintenance table are connected. The rail changing device comprises a movable track, a walking base, a transmission mechanism and a locking mechanism. The movable track is parallel to the plate transfer main track and is installed on the walking base. The transmission mechanism is connected with the walking base and drives the movable track and the walking base to move on the transverse translation track. The locking mechanism is installed on the butt joint platform of the plate transfer main track and is located on both sides of the movable track.

[0006] Furthermore, the movable track is installed on the traveling base, and the bottom of the traveling base is equipped with rollers to support its lateral movement on the transverse translation track for track changing. The transverse translation track is fixed on the ground foundation, and the transmission mechanism is installed on the ground foundation. The transmission mechanism is a chain drive, with one chain plate fixed to the traveling base. The driving sprocket is installed on the output shaft of the motor reducer. Two bearing seats are installed on the other side of the transmission mechanism, and the driven shaft is installed in the bearing seats. The driven sprocket is installed on the driven shaft. The motor drives the driving sprocket to drive the chain, transmitting power to the traveling base, thereby enabling the movable track to change tracks between the main plate transfer track and the maintenance platform.

[0007] Furthermore, the locking mechanism is mounted and fixed on a bracket connected to the main track for electrode plate transfer. There are two locking mechanisms on each side of the movable track, each including a second motor, a crank, a connecting rod, a connecting rod pin, a connecting sleeve, a positioning shaft, and a bushing. The crank is mounted and fixed on the motor shaft, and the crank and connecting sleeve are connected by the connecting rod. The connecting sleeve is mounted on the positioning shaft, which engages with the bushing and moves linearly within the bushing. When the main track for electrode plate transfer and the movable track are in the docking position, the positioning shaft of the locking mechanism, driven by the second motor, passes through the bushing and the positioning bushing on the traveling base. This locking mechanism can lock the movable track and the main track for electrode plate transfer after docking.

[0008] Limit switches are installed on the main track support for electrode plate transfer to determine whether the movable track has reached the docking position when the movable track and the main track for electrode plate transfer are docked.

[0009] Limit switches are installed on the maintenance platform track to determine whether the movable track has reached the docking position when it is connected to the maintenance platform.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The transmission system of the track-changing device adopts a chain drive, which allows the faulty transfer trolley to be moved a considerable distance via the movable track. Correspondingly, the maintenance platform can be placed at a distance from the normal operating track of the electrode plate transfer trolley, ensuring sufficient maintenance space for the faulty trolley and protecting the personal safety of maintenance personnel. By incorporating a locking mechanism, the track-changing device achieves good docking accuracy and stability after returning to the main electrode plate transfer track, addressing the issue of poor rigidity between the movable track and the main electrode plate transfer track, reducing impact and wear between the electrode plate transfer trolley and the track, and extending the service life of both the track-changing device and the track.

The polar plate transfer main track 200 comprises a main track one 201 before the orbit changing device and a main track two 202 after the orbit changing device. The orbit changing device comprises a movable track 401, a walking base 402, a transverse translation track 500, a transmission mechanism 600 and a locking mechanism 700. When the polar plate transfer trolley normally operates, the movable track 401 is connected with the main track one 201 and the main track two 202, and the locking mechanism 700 is in a locking state to connect the main track one 201, the main track two 202 and the movable track 401. When the polar plate transfer trolley 100 fails and needs to be transferred to the maintenance table 300, the locking mechanism 700 is retracted to disconnect the main track one 201, the main track two 202 and the movable track 401. The faulted polar plate transfer trolley 100 is changed track on the transverse translation track 500 through the transmission mechanism 600, and is moved from the butt joint position of the main track one 201 and the main track two 202 to the butt joint position of the maintenance table 300, and then enters the maintenance table 300 for maintenance. After the transfer of the faulted polar plate transfer trolley 100 is completed, the movable track 401 returns to the butt joint position of the main track one 201 and the main track two 202, the locking mechanism 700 is started, and the movable track 401 and the walking base 402 are locked. The number of the locking mechanism 700 is determined by the machining precision and the actual track load condition, and is not specifically limited.

The driving sprocket 603 is installed on the output shaft of a speed reducer 605, and a motor 606 is installed on the input end of the speed reducer 605. The driven sprocket 604 is installed on a driven shaft 607, and a bearing seat 608 is installed on each end of the driven shaft 607. The bearing seat 608 is installed on a base plate 609.
