Description

Technical Field

[0002] During the production of metal workpieces, it is necessary to perform quenching heat treatment on them to improve the strength of the metal workpieces themselves. Usually, a trolley tempering furnace is used for the quenching treatment of metal workpieces. It can transfer the workpieces into the furnace body through a trolley for heating treatment. Under the existing technology, the trolley tempering furnace usually uses heating rods for heating. The heating rods are generally fixedly installed on both sides inside the furnace body. In order to ensure the heating effect inside the furnace, a plurality of heating rods need to be installed inside the furnace body.

The anti-rotation plug column 83 is inserted into the matching anti-rotation hole 33. In addition, when the locking carrier column 71 fixes the heating rod 8, it is inserted into the locking jack 81.

[0045] When installing the heating rod 8, the installation post 82 is inserted into the installation jack 32 to position the heating rod 8 on the movable installation platform 3. After all the heating rods 8 on one side of the furnace body 1 are placed, the driving carrier bar 2 is pushed upward at this time. Under the cooperation of the connection channel 24 on the driving carrier bar 2 and the connection plug rod 371, the movable installation platform 3 is driven to move into the installation slot 12, so that part of the movable installation platform 3 is inserted into the installation slot 12, and then the heating rod 8 is driven to be inserted into the installation slot 12 and moved to the working position. During the movement of the movable installation platform 3, under the action of the first connection and cooperation rod 361, it will push the movable connection block 4 upward. As the movable connection block 4 moves upward, since the connection support rod 43 on the movable connection block 4 is inserted into the connection through hole 52 on the first protective frame 5, the movable connection block 4 will also drive the first protective frame 5 to move upward, making part of it protrude above the movable installation platform 3. Thus, under the action of the first protective frame 5, it can play a protective role for the heating rod 8. And as the movable installation platform 3 moves, under the action of the second connection and cooperation rod 45, the second protective frame 6 will be driven to move, so that the two second protective frames 6 on the movable installation platform 3 move toward each other and close together. In this way, the second protective frame 6 can also play a protective role for the heating rod 8. Therefore, under the cooperation of the first protective frame 5 and the second protective frame 6, the safety of the heating rod 8 in the working state can be fully guaranteed, avoiding it from being hit by external forces. In addition, when the first protective frame 5 moves upward, under the cooperation of the connection carrier frame 56 and the connection plug post 76, the two locking carrier plates 7 will be driven to move toward each other, so that the locking carrier posts 71 on the locking carrier plates 7 are inserted into the locking jacks 81 on the heating rod 8. Thus, the heating rod 8 can be fixed under the action of the locking carrier posts 71, and the synchronous installation and fixation of multiple heating rods 8 can be achieved at the same time, which is very convenient and fast. When the driving carrier bar 2 does not move upward and the heating rod 8 is in the unlocked state, at this time, the first protective frame 5 is located below the heating rod 8, and the second protective frame 6 is not closed together, which is convenient for the staff to operate the heating rod 8 and facilitate the taking and placing of the heating rod 8. When the driving carrier bar 2 moves upward, when the positioning carrier bar 27 on the driving carrier bar 2 moves to the support slot 18, the positioning carrier bar 27 is pulled toward the support slot 18 at this time, so that the plugging support plate 29 on the positioning carrier bar 27 is inserted into the support slot 18. The support slot 18 supports the positioning carrier bar 27. At the same time, the positioning through hole 291 on the plugging support plate 29 is aligned with the positioning jack 191 on the positioning support plate 19, and then the positioning pin 292 is passed through the positioning through hole 291 and inserted into the positioning jack 191 to fix the positioning carrier bar 27, and at the same time, the driving carrier bar 2 is fixed, ensuring the firm installation of the heating rod 8. The operation is simple. When the heating rod 8 needs to be disassembled, only by moving the driving carrier bar 2 downward can the heating rod 8 be unlocked, and at the same time, it is driven by the movable installation platform 3 to move out of the installation slot 12 for easy operation.
