[0002] The heating furnace of the conventional tempering production line and the heating furnace of the laminated production line need to be raised during the maintenance stage. In order to prevent the lifting cylinder from falling suddenly, a plug rod (safety pin) needs to be inserted under the lifting rod;

[0003] However, since the furnace body is huge and has many plug rods (safety pins), at least 4 for one furnace body, there is a possibility that the furnace body will be lowered without removing the plug rods (safety pins) in time after maintenance is completed, resulting in the plug rods (safety pins) being forcibly broken. At the same time, if the plug rods (safety pins) are not inserted during the maintenance process, there will be a safety risk when people enter the furnace body, but it is also inconvenient to confirm that each plug rod (safety pin) is installed in place. For this reason, the utility model proposes a furnace body lifting and anti-collision equipment to solve the above technical problems. Utility Model Content

[0019] In this embodiment: the lower fixed column 11 supports the upper lifting column 12 through four hydraulic telescopic machines 14, the upper lifting column 12 supports and adjusts the height of the inner lifting column 13 and the furnace body 1, the lower fixed column 11 slides and guides and limits the inner lifting column 13, when the furnace body 1 is raised, the inner lifting column 13 follows the upper lifting column 12 to rise, and the bottom height of the inner lifting column 13 exceeds the height of several plug holes 111, the lower fixed column 11 supports several plug rods 2 through several lug plates 112, the plug rod 2 is between the two lug plates 112, the plug rod 2 can be flipped, and the plug rod 2 can be switched between vertical and horizontal states. When the plug rod 2 is in a vertical state, the plug rod 2 is attached to one side of the lower fixed column 11, without The insertion rod 2 needs to be stored separately and the space occupied by the insertion rod 2 needs to be reduced. When the insertion rod 2 is flipped upward to a horizontal state, one end of the insertion rod 2 is aligned with the corresponding insertion hole 111. By pushing the insertion rod 2, the insertion rod 2 can be inserted into the insertion hole 111. At this time, the insertion of the insertion rod 2 will not be limited by the internal lifting column 13. Then the insertion rod 2 is inserted into another insertion hole 111 and extends out of the other side of the lower fixed column 11. The lower fixed column 11 supports the L-shaped support plate 3, the L-shaped support plate 3 supports a plurality of sound and light alarms 31 and a plurality of vertical plates 4, the vertical plates 4 support the corresponding support tubes 41, the support tubes 41 support the upper sliding rod 42 and the lower sliding rod 43, the upper sliding rod 42 and the lower sliding rod 43 squeeze and trigger the corresponding touch-pressure switch 44, and The touch-pressure switch 44 corresponding to the upper slide bar 42 is triggered and controlled by the sound and light alarm 31 on one side of the L-shaped support plate 3. When the furnace body 1 is raised, before the upper slide bar 42 applies pressure to the corresponding touch-pressure switch 44, the sound and light alarm 31 sends out a sound and light alarm. When the touch-pressure switch 44 below is squeezed, an electrical signal is generated. This signal is transmitted to the sound and light alarm 31 as an input signal. The control circuit inside the sound and light alarm 31 receives the input signal and performs corresponding signal processing and analysis. Once the control circuit confirms that the signal has been received, it triggers the sound and light output components to start working, emitting sound and flashing light to remind the staff to install the insertion rod 2 and reminding the personnel to enter the furnace body 1 that there is a safety risk. This is a simple disclosure of its technical principle. There is at least one way to implement it. The upper slide bar 42 and the lower slide bar 43 are aligned with one end of the insertion rod 2. The insertion rod 2 passes through the two insertion holes 111 to reach the position of the upper slide bar 42 and contact and squeeze it, so that the upper touch-pressure switch 44 can control the corresponding sound and light alarm 31 to no longer emit the sound and light alarm, so that several insertion rods 2 can be located below the inner lifting column 13 to provide safety protection. As the insertion rod 2 continues to be pushed, the insertion rod 2 pushes the upper slide bar 42 and the upper touch-pressure switch 44 to slide, the insertion rod 2 contacts and squeezes the lower slide bar 43, and the lower slide bar 43 squeezes the lower touch-pressure switch 44. The lower touch-pressure switch 44 is connected to the control system of the hydraulic telescopic machine 14. When the lower slide bar 43 squeezes the touch-pressure switch 44 and triggers it, the hydraulic telescopic machine 14 can be automatically locked.It is impossible to retract and retract. The switch control usage is the existing technology and is not an improvement point of the present invention. Its triggering principle will not be repeated here, so that a furnace body 1 can achieve a stable state after being lifted. If the plug rod 2 is not pulled out in time after the furnace body 1 is repaired, the hydraulic telescopic machine 14 is controlled to lower the furnace body 1. At this time, the instruction cannot be completed, thereby preventing the plug rod 2 from being forcibly disconnected, further ensuring the safe and stable operation of the device. When the plug rod 2 is taken out, the hydraulic telescopic machine 14 can control the furnace body 1 to descend, and the sound and light alarm 31 stops the alarm after the furnace body 1 is lowered. The sound and light alarm 31 is connected to the control end of the furnace body 1 by signal. Because the structure of the furnace body 1 has not been improved in the present utility model, the sound and light alarm 31 stops the alarm after the furnace body 1 is lowered. The signal transmission principle of the furnace body 1 rising to turn on the alarm is a well-known technology in the field and will not be repeated in this scheme. ,

One end of the torsion spring is installed in the installation space inside the ear plate 112, and the other end of the torsion spring is fixedly connected to the side wall of the four-sided rod 113. The torsion spring drives the four-sided rod 113 to rotate with the ear plate 112 as the support base point, and the four-sided rod 113 drives the corresponding insertion rod 2 to rotate downward, so that the insertion rod 2 can automatically flip downward and fold after being pulled out to achieve storage and prevent the insertion rod 2 from swinging.

[0021] One side of the lower fixed column 11 is rotatably connected to an L-shaped limit rod 5, and one side of the L-shaped limit rod 5 is fixedly connected to a second magnetic plate 51.

[0023] One end of one of the touch-pressure switches 44 is fixedly connected to a guide support rod 46, a return spring 45 is sleeved on the side wall of the corresponding guide support rod 46, and the guide support rod 46 is slidably connected to the inner wall of the vertical plate 4, wherein a delay device 441 is provided on one side of the other touch-pressure switch 44; the return spring 45 pushes the upper touch-pressure switch 44 outward, so that the insertion rod 2 can first contact the upper slide rod 42, and when the insertion rod 2 pushes the upper slide rod 42 and the corresponding touch-pressure switch 44, the vertical plate 4 guides the upper slide rod 42 and the corresponding touch-pressure switch 44 through the guide support rod 46, so that the upper slide rod 42 and the corresponding touch-pressure switch 44 are slidably guided. The rod 42 can slide stably. When the delay device 441 moves down the sliding rod 43 and squeezes the lower touch-pressure switch 44, the lower touch-pressure switch 44 can control the hydraulic telescopic machine 14 to be temporarily unable to extend and retract. When the insertion rod 2 is pulled out, the touch-pressure switch 44 pushes the sliding rod 43 to pop out. At this time, the touch-pressure switch 44 can release the control of the hydraulic telescopic machine 14. At the same time, the release signal of the lower touch-pressure switch 44 is delayed and transmitted through the delay device 441. The hydraulic telescopic machine 14 can be controlled after the delay of the delay device 441, so that the staff can obtain time to take out the insertion rod 2.
