Description

Technical Field

[0001] This utility model belongs to the field of volume measurement, and in particular relates to a volume calibration and testing device. Background Technology

[0002] Long-term use of metal cans can lead to deformation and corrosion, which not only affects the accuracy of the can's volume but may also weaken its structural strength. This is especially true for multi-layered cans, where the deformation or corrosion of the outer layer cannot determine the impact on the inner layers. Therefore, calibration testing of the inner layers is necessary. Currently, a motor-driven lifting device is commonly used to inspect the can's interior. To prevent a collision between the instrument and the can in case of a sudden power outage, a motor with a brake function is typically used. However, a motor with a brake function cannot rotate without power, preventing the lifting device from continuing to move. Sometimes, even if the instrument has its own power supply, the inability to continue lifting prevents further volume measurement, causing inconvenience. Therefore, designing a testing device that prevents the lifting module from falling and allows for manual continuation of lifting in the event of a power outage is crucial. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a detection device that can prevent the lifting module from falling when the power is off and can continue to lift manually, thereby improving the stability of the detection device and improving the detection efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides a volume calibration and testing device, including a lifting rod with a testing device that can move up and down on the lifting rod; a lifting base that can slide along the vertical direction on the lifting rod, a lifting slider between the lifting base and the lifting rod, the lifting slider being slidably connected to a lifting slide rail, the lifting slide rail being fixed to the lifting rod, a lifting rack on one side of the lifting rod, the lifting rack meshing with a lifting gear, the lifting gear being connected to a lifting drive motor that drives its rotation; the lifting rack can slide up and down relative to the lifting rod, and a locking assembly is provided between the lifting rack and the lifting rod to limit the sliding state of the lifting slider; the locking assembly includes multiple sets of cooperating lifting stops and clearance holes, the lifting stops being slidable relative to the lifting rod in the front-back direction, and the lifting rack... The lifting rack is provided with multiple clearance holes that cooperate with the lifting stop. The sliding stroke of the lifting rack is equal to the distance from the lifting stop to the clearance hole. When the lifting rack slides to the lower position, one end of the lifting stop contacts the lifting rack, and the other end of the lifting stop restricts the sliding of the lifting slider. When the lifting rack slides to the upper position, one end of the lifting stop contacts the clearance hole, and the other end of the lifting stop releases the restriction on the lifting slider. The upper end of the lifting rod is provided with a fixed base fixed thereto. An electromagnet for pulling the lifting rack is fixed on the fixed base, and a magnetic block for attracting the electromagnet is fixed on the lifting rack. A return spring is provided between the magnetic block and the fixed base. A traction screw passes through the inner side of the magnetic block, and the traction screw is threaded to the fixed base.

[0005] This invention utilizes a locking assembly between the lifting rack and the lifting rod. A lifting stop within this assembly restricts or releases the sliding motion of the lifting slider based on the position of the lifting rack, thus limiting the sliding of the lifting base, which houses the detection component, relative to the lifting rod. Electromagnets fixed to the base and magnetic blocks fixed to the lifting rack alter the position of the lifting rack relative to the lifting rod through electromagnetic interaction. When the equipment experiences a sudden power outage, the electromagnetic effect disappears, the lifting rack is at its lower position, and the lifting stop prevents the sliding slider from sliding. This avoids the problem of the detection component falling to the lower end of the lifting rod and colliding with the tank, potentially damaging the instrument, if the lifting drive motor loses power due to a power outage. When the instrument needs to be raised or lowered during a power outage, the lifting rack can be manually moved to its upper position by rotating the traction screw, allowing the lifting slider to continue sliding.

[0006] Preferably, the lifting rod is provided with a T-shaped sliding groove, one end of the sliding groove is close to the lifting rack, the other end of the sliding groove is close to the lifting slider, the lifting stop is disposed inside the sliding groove and can slide, one end of the lifting stop can contact the lifting slider, and the other end of the lifting stop passes through the sliding groove.

[0007] Preferably, the front-to-back width of the lifting stop is greater than the distance from the lifting slider to the lifting rack. Both ends of the lifting stop have inclined surfaces, which, when subjected to force, generate a force to drive the lifting stop to slide. The inclined surface of the lifting stop near the end of the lifting slider can contact the lifting slider. When the lifting rack is in the lower position, one end of the lifting stop contacts the lifting rack, and the other end of the lifting stop restricts the sliding of the lifting slider. When the lifting rack is in the upper position, the end of the lifting stop near the lifting rack can enter the inner side of the clearance hole, and the inclined surface of that end of the lifting stop can contact the clearance hole. When the inclined surface of the lifting stop contacts the clearance hole, the restriction of the lifting stop on the lifting slider is released.

[0008] Preferably, the lifting block is provided with a stop pin to limit its sliding range, and the forward and backward sliding range of the lifting block is not less than the contact distance between the lifting block and the lifting slider; when the lifting block slides to the foremost position, the rear side of the lifting block is located within the range of the sliding groove; the rear stop pin is set at the large end of the rear inclined surface of the lifting block to prevent the rear inclined surface of the lifting block from completely entering the inner side of the clearance hole, and to ensure that the clearance hole is in contact with the inclined surface of the lifting block.

[0009] Preferably, the diameter of the clearance hole is smaller than the vertical height of the lifting block, so as to prevent the lifting block from completely entering the inside of the clearance hole. Attached Figure Description

[0017] See attached document Figure 1 Appendix Figure 2 The volume calibration and testing device provided by this utility model includes a lifting rod 301 as the lifting body, a lifting base 302 that can move up and down on the lifting rod 301, and a testing component for testing on the lifting base 302.

[0018] The lifting rod 301 is provided with a lifting base 302 that can slide along its vertical direction. A detection component, such as a detection instrument, is connected to the lifting base 302. A lifting slider 303 is provided between the lifting base 302 and the lifting rod 301. One side of the lifting slider 303 is fixed to the lifting base 302, and the other side of the lifting slider 303 is slidably connected to a lifting slide rail 304 that is fixed to the lifting rod 301. The lifting slider 303 is provided with a dovetail groove, and the lifting slide rail 304 is provided with a slide path that cooperates with the dovetail groove. The lifting slide rail 304 is arranged along the vertical direction of the lifting rod 301. A lifting rack 305 arranged vertically is provided on one side of the lifting rod 301. The lifting rack 305 meshes with a lifting gear. The lifting gear is connected to a lifting drive motor that drives its rotation. The lifting drive motor is fixed to the lifting base 302. The lifting rack 305 can slide vertically relative to the lifting rod 301, and a locking component is provided between the lifting rack 305 and the lifting rod 301 to limit the sliding state of the lifting slider 303.

[0019] The lifting rack 305 can slide relative to the lifting rod 301 within a certain range. Those skilled in the art can achieve the sliding of the lifting rack 305 relative to the lifting rod 301 by setting a T-slot in the vertical direction of the lifting rod 301 and setting a slide rail that cooperates with the T-slot in the lifting rack 305.

[0020] See Figure 3 and Figure 5The snap-fit ​​assembly includes multiple sets of cooperating lifting blocks 307 and clearance holes 310. The lifting blocks 307 can slide relative to the lifting rod 301 in the front-back direction. The lifting rack 305 is provided with multiple clearance holes 310 that cooperate with the lifting blocks 307. The travel of the lifting rack 305 is limited to the distance from the lifting blocks 307 to the clearance holes 310. When the lifting rack 305 slides to the lower position, one end of the lifting blocks 307 contacts the lifting rack 305, and the other end of the lifting blocks 307 can limit the sliding of the lifting slider 303. When the lifting rack 305 slides to the upper position, one end of the lifting blocks 307 contacts the clearance holes 310, and the other end of the lifting blocks 307 releases the restriction on the lifting slider 303. The lifting rod 301 is provided with a T-shaped sliding groove 308. The larger end of the sliding groove 308 is close to the lifting rack 305, and the smaller end of the sliding groove 308 is close to the lifting slider 303. A lifting stop 307 is disposed inside the sliding groove 308 and can slide. One end of the lifting stop 307 can contact the lifting slider 303, and the other end of the lifting stop 307 passes through the sliding groove 308. The front-to-back width of the lifting stop 307 is greater than the distance from the lifting slider 303 to the lifting rack 305. Both ends of the lifting stop 307 are provided with inclined surfaces, which can generate a force to drive the lifting stop 307 to slide when subjected to force. The end of the lifting stop 307 near the lifting slider 303... The inclined surface can contact the lifting slider 303; when the lifting rack 305 is in the lower position, when one end of the lifting stop 307 contacts the lifting rack 305, the other end of the lifting stop 307 can restrict the sliding of the lifting slider 303; when the lifting rack 305 is in the upper position, the end of the lifting stop 307 near the lifting rack 305 can enter the inner side of the clearance hole 310, and the inclined surface of the lifting stop 307 at this end can contact the clearance hole 310. When the inclined surface of the lifting stop 307 contacts the clearance hole 310, the restriction of the lifting stop 307 on the lifting slider 303 can be released; the lifting stop 307 is provided with a stop pin 309 to limit its sliding range, see [reference]. Figure 5 The forward and backward sliding range of the lifting stop 307 is not less than the contact distance between the lifting stop 307 and the lifting slider 303. Figure 5In the middle, when the lifting stop block 307 slides to the foremost position, the minimum distance between the front stop pin 309 and the lifting rod 301 is the range of motion D of the lifting stop block 307, which is not less than the distance C between the front side of the lifting stop block 307 and the rear side of the lifting slider 303. This ensures that when the lifting stop block 307 slides to the rearmost position, the lifting stop block 307 can release its contact with the lifting slider 303. At the same time, as shown in the figure, when the lifting stop block 307 slides to the foremost position, the rear side of the lifting stop block 307 is located within the range of the sliding groove 308; the rear stop pin 309 is set at the large end of the rear inclined surface of the lifting stop block 307 to prevent the rear inclined surface of the lifting stop block 307 from completely entering the inner side of the clearance hole 310, ensuring that the clearance hole 310 contacts the inclined surface of the lifting stop block 307. It is also possible to prevent the lifting block 307 from completely entering the inside of the clearance hole 310 by limiting the diameter of the clearance hole 310 to be smaller than the vertical height of the lifting block 307.

[0021] See Figure 4 The upper end of the lifting rod 301 is provided with a fixed base 101 fixedly connected to it. An electromagnet 306 for pulling the lifting rack 305 is fixed on the fixed base 101. A magnetic block 311 for attracting the electromagnet 306 is fixedly connected to the lifting rack 305. When the electromagnet 306 is energized, the magnetic force acts on the magnetic block 311 and drives the magnetic block 311 to move upward, realizing the function of the electromagnet 306 driving the lifting rack 305 to move upward, so that the lifting rack 305 is in the upper position. A spring is provided between the magnetic block 311 and the fixed base 101. When the electromagnet 306 is de-energized, the spring causes the magnetic block 311 and the lifting rack 305 to move downward. At the same time, a traction screw 312 is provided inside the magnetic block 311 and is threadedly connected to the fixed base 101.

[0022] With the above structure, in use, the traction screw 312 is rotated to the lower position; first, the electromagnet 306 is energized, and the electromagnet 306 generates magnetic force to drive the lifting rack 305 to the upper position, and the return spring is in a compressed state; at this time, the clearance hole 310 is at the same height as the lifting stop 307; then, the lifting drive motor is controlled to rotate, and the lifting slider 303 moves along the lifting slide rail 304. When the lifting slider 303 contacts the inclined surface of the lifting stop 307, the inclined surface of the lifting stop 307 is subjected to force, generating a force to drive the lifting stop 307 to slide. The lifting stop 307 slides towards the position close to the lifting rack 305, and the end of the lifting stop 307 close to the lifting rack 305 can slide to the inside of the clearance hole 310. At this time, the lifting stop 307... 7. The lifting slider 303 can slide normally by avoiding the lifting slide 303. When the detection device is suddenly powered off, the electromagnet 306 loses its magnetic force, and the return spring resets, causing the lifting rack 305 to move downward. When the lifting rack 305 moves downward, the inner wall of the avoidance hole 310 contacts the inclined surface of the lifting stop 307 and pushes the lifting stop 307 away from the avoidance hole 310. The lifting stop 307 moves forward. As the lifting rack 305 moves downward, the avoidance hole 310 and the lifting stop 307 are misaligned. At this time, when the lifting slider 303 contacts the inclined surface of the lifting stop 307, the other end of the lifting stop 307 contacts the lifting rack 305 and cannot move. The lifting slider 303 cannot push the lifting stop 307, and the lifting stop 307 restricts the lifting slider 303 from continuing to slide. To prevent the lifting drive motor from losing power and causing the detection component to fall to the lower end of the lifting rod 301 and collide with the tank, thus damaging the detector, when the equipment experiences a power outage for other reasons. Since multiple lifting stops 307 are provided in the vertical direction, the corresponding lifting stops 307 can prevent the lifting slider 303 from falling at any position on the lifting rod 301, thus avoiding a collision between the detector and the tank. When the power is off, if it is necessary to move the detection component connected to the lifting base 302, i.e., when the lifting slider 303 needs to continue sliding, the traction screw 312 is rotated. Since the traction screw 312 is threadedly connected to the fixed base 101 and passes through the inner side of the magnetic block 311, rotating the traction screw 312 can drive the magnetic block 312 to move upward. Since the magnetic block 312 is fixedly connected to the lifting rack 305, rotating the traction screw 312 can position the lifting rack 305 at the upper end. At this time, the lifting base 302 can be manually slid. This invention, through this structure, allows the power supply system of the detection component to be grouped, supplying power to the lifting device and the detection component separately. Even after the lifting device is powered off, the magnetic block 311 and the lifting rack 305 can still be positioned at the upper end by rotating the traction screw 312, allowing manual driving of the lifting base 302 to move up and down to complete the tank volume detection.

[0023] This invention utilizes a locking assembly between the lifting rack and the lifting rod. A lifting stop within this assembly restricts or releases the sliding motion of the lifting slider based on the position of the lifting rack, thus limiting the sliding of the lifting base, which houses the detection component, relative to the lifting rod. Electromagnets fixed to the base and magnetic blocks fixed to the lifting rack alter the position of the lifting rack relative to the lifting rod through electromagnetic interaction. When the equipment experiences a sudden power outage, the electromagnetic effect disappears, the lifting rack is at its lower position, and the lifting stop prevents the sliding slider from sliding. This avoids the problem of the detection component falling to the lower end of the lifting rod and colliding with the tank, potentially damaging the instrument, if the lifting drive motor loses power due to a power outage. When the instrument needs to be raised or lowered during a power outage, the lifting rack can be manually moved to its upper position by rotating the traction screw, allowing the lifting slider to continue sliding.

[0024] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
