Description

Technical Field

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

[0002] Metal tanks, as common industrial equipment, are frequently used as storage devices in industries such as petroleum, chemical, and brewing. Long-term use of metal tanks can lead to deformation and corrosion, which not only affects the accuracy of the tank's volume but may also weaken its structural strength. Therefore, regular volume measurement is necessary. Regular volume measurement allows for the timely detection of these problems, enabling appropriate measures to be taken to prevent safety accidents such as tank rupture. Currently, most tank volume measurement methods use 3D scanning to scan the inside of the tank and then calculate the actual internal volume. The current method requires placing the testing device inside the tank and removing it afterward, which increases the workload for workers and is inefficient. Given these issues, designing a testing device that improves efficiency is crucial. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a volume measurement and detection device that can be fixed at the inlet of the tank and extend the detection device into the tank through an inverted structure to detect the volume of the tank, thereby improving detection efficiency and reducing the workload of the staff.

[0004] To solve the above-mentioned technical problems, this utility model provides a volume measurement and detection device, including a lifting rod that can extend into the tank body, a rotary detection device that can move up and down around the outer side of the lifting rod, and a fixing device that can be fixed to the tank body at the upper end of the lifting rod; a lifting base that can slide along its vertical direction is provided on the lifting rod, and a lifting slider is provided between the lifting base and the lifting rod, one side of the lifting slider is fixedly connected to the lifting base, and the other side of the lifting slider is slidably connected to a lifting slide rail; a lifting rack is provided on one side of the lifting rod, the lifting rack meshes with a lifting gear, the lifting gear is connected to a lifting drive motor that drives its rotation, and the lifting drive motor is fixedly connected to the lifting base; the lifting base is connected to a rotary detection device, the rotary detection device including the lifting base... A fixed detection base is provided, with a through hole in the middle for the lifting rod to pass through. A rotary gear disk that rotates relative to the detection base is provided on the lower side of the detection base. A set of detection instruments for detection is fixedly connected to the lower side of the rotary gear disk. The fixing device includes a fixed base fixedly connected to the lifting rod. The fixed base can contact the flange of the tank. A linkage gear is rotatably connected to the fixed base. The linkage gear meshes with two sets of cleats for cooperation. The two sets of cleats are respectively arranged on both sides of the linkage gear. Each cleat includes a sliding rod that is slidably connected to the fixed base. A clamping block for fixing the flange of the tank is provided at one end of the sliding rod away from the linkage gear. A threaded rod is provided between the clamping block and the sliding rod. The threaded rod passes through the clamping block and is threadedly connected to the sliding rod.

[0005] This invention, through the above structure, allows for volume measurement of a tank. A lifting rod is inserted into the tank to fix the detection device to it. The fixing base is placed close to the flange end of the tank. Pulling one of the sliding rods causes the sliding rod to rotate, which in turn drives the other sliding rod to slide in the opposite direction. The two sliding rods slide in opposite directions, increasing the distance between the clamping blocks on them. The two clamping blocks are placed on the lower sides of both ends of the flange, positioning the flange between the clamping blocks and the sliding rods. Rotating the threaded rod brings the clamping blocks closer to the flange. After the clamping blocks contact the flange, tightening the threaded rod fixes the flange between the clamping blocks and the sliding rods. The detector is then started to perform a horizontal scan of the interior. Driven by the rotary drive motor, the detector rotates to measure the length or width of the horizontal plane. Starting the lifting drive motor, since the detection base and the lifting base are fixedly connected, allows the lifting base to move the detection base up and down, thus moving the detector up and down to measure the length or width at different heights within the tank, fulfilling the need for volume measurement.

[0006] Preferably, one side of the linkage gear is further provided with an anti-rotation device to limit its rotation. The anti-rotation device includes an anti-rotation plate that can mesh with the linkage gear. The end of the anti-rotation plate is provided with gear teeth that can mesh with the linkage gear. The anti-rotation plate is slidably connected to an anti-rotation seat that is fixed to the fixed base. The anti-rotation seat is provided with an anti-rotation driving device that drives the anti-rotation plate to slide left and right. When the anti-rotation plate meshes with the linkage gear, it can prevent the linkage gear from rotating.

[0007] Preferably, the anti-rotation drive device includes an adjusting rod capable of controlling the movement of the anti-rotation plate. The middle part of the anti-rotation plate is slidably connected to the anti-rotation seat, and the other end of the anti-rotation plate is provided with an adjusting rod rotatably connected thereto. The adjusting rod is threadedly connected to the anti-rotation seat. The end of the anti-rotation plate is provided with a T-slot, and the end of the adjusting rod is provided with a boss that mates with the T-slot. The middle part of the adjusting rod is threadedly connected to the anti-rotation seat, and the other end of the adjusting rod extends to the outside of the anti-rotation seat.

[0008] In summary, this utility model, by setting a fixing device that is fixed to the tank body, adopts an inverted method to inspect the inside of the tank. The fixing device is fixed to the flange of the tank body by the fixing device. By setting a lifting base that slides up and down on the lifting rod, the rotating inspection device is driven to inspect the length and width dimensions at different heights inside the tank. This avoids the problem of having to place the inspection device inside the tank during inspection and improves the efficiency of the inspection work. Attached Figure Description

Detailed Implementation

[0017] See attached document Figure 1 To the attached Figure 4 The volume measurement and detection device provided by this utility model includes a lifting rod 301 that can extend into the tank body, a rotating detection device that can move up and down is provided on the outer ring of the lifting rod 301, and a fixing device that can be fixed to the tank body is provided at the upper end of the lifting rod 301.

[0018] The lifting rod 301 is provided with a lifting base 302 that can slide along its vertical direction. A lifting slider 303 is provided between the lifting base 302 and the lifting rod 301. One side of the lifting slider 303 is fixedly connected to the lifting base 302, and the other side of the lifting slider 303 is slidably connected to the lifting rail 304. The lifting slider 303 is provided with a dovetail groove, and the lifting rail 304 is provided with a slide rail that mates with the dovetail groove. The lifting rail 304 is arranged along the vertical direction of the lifting rod 301 and is fixedly connected to the lifting rod 301. One side of the lifting rod 301 is provided with a vertically arranged lifting rack 305. The lifting rack 305 meshes with a lifting gear, and the lifting gear is connected to a lifting drive motor that drives its rotation. The lifting drive motor is fixedly connected to the lifting base 302. Those skilled in the art can select a motor with a braking function as the lifting drive motor to avoid the problem of the lifting structure losing traction and falling to the bottom of the lifting rod 301 and causing a collision due to a sudden power failure during operation.

[0019] With the above structure, when the lifting drive motor drives the lifting gear to rotate, the lifting gear rotates relative to the lifting rack 305. The lifting drive motor is fixed to the lifting base 302, so the lifting base 302 can move up and down along the lifting rack 305.

[0020] See appendix Figures 1 to 3The lifting base 302 is connected to a rotary detection device, which includes a detection base 201 fixedly connected to the lifting base 302. The detection base 201 has a through hole in the middle for the lifting rod 301 to pass through. A rotary gear disk 203 rotating relative to the lower side of the detection base 201 is provided. A set of detection instruments 204 for detection is fixedly connected to the lower side of the rotary gear disk 203. A rotating component 202 is provided at the lower end of the detection base 201, and the rotating component 202 is connected to the rotary gear disk 203. The outer side of the rotary gear disk 203 is provided with a rotating component 202 connected to the rotary gear disk 203. The rotating gear meshes with a rotary gear, which is connected to a rotary drive motor that drives its rotation. The rotary drive motor is fixedly connected to the detection base 201. In this utility model, the rotating component 202 can be a bearing with a seat. The seat of the bearing with a seat is connected to the detection base 201, and the rotating part of the bearing with a seat is connected to a rotary gear disk 203, so that the rotary gear disk 203 can rotate relative to the detection base 201. At the same time, the detector 204 rotates relative to the detection base 201, so that the detector 204 rotates relative to the lifting rod 301.

[0021] With the above structure, when the rotary drive motor drives the rotary gear to rotate, the rotary gear meshes with the rotary gear disk 203 and drives the rotary gear disk 203 to rotate. At the same time, the rotary gear disk 203 drives the detector 204 to rotate relative to the detection base 201. By using the detectors 204 in groups and placing them on both sides of the rotary gear disk 203, the balance of the rotary gear disk 203 can be maintained. Furthermore, by using two detectors 204 as the main detector and the auxiliary detector, respectively, the accuracy of the detection data can be improved.

[0022] With the above structure, this utility model requires that, for safety reasons, the tank interior must be cleaned and fully ventilated before volume testing. The lifting rod 301 is inserted into the tank, and the detector 204 is activated to perform a horizontal scan. Driven by the rotary drive motor, the detector 204 rotates to measure the length or width of the horizontal plane. The lifting drive motor is then activated. Since the detection base 201 is fixedly connected to the lifting base 302, the lifting base 302 can move the detection base 201 up and down, thus moving the detector 204 up and down to measure the length or width at different heights within the tank, thereby achieving the detection of the tank's internal volume.

[0023] See Figure 2 , Figure 5 and Figure 6 The fixing device includes a fixing base 101 fixedly connected to the lifting rod 301. The fixing base 101 can contact the flange of the tank body. See [link to documentation]. Figure 5A linkage gear 105 is rotatably connected to the fixed base 101. The linkage gear 105 meshes with two sets of pawls for cooperative use. The two sets of pawls are respectively set on both sides of the linkage gear 105. Each pawl includes a sliding rod 102 that is slidably connected to the fixed base 101. The sliding rod 102 is L-shaped. A slide rail is provided between the long end of the sliding rod 102 and the fixed base 101. The sliding rod 102 is provided with gear teeth that mesh with the linkage gear 105. The end of the sliding rod 102 away from the linkage gear 105 is provided with a clamping block 104 for fixing the tank flange. That is, the short end of the sliding rod 102 is provided with a clamping block 104 for fixing the flange. A threaded rod 103 is provided between the clamping block 104 and the sliding rod 102. The threaded rod 103 passes through the clamping block 104 and is threadedly connected to the sliding rod 102.

[0024] With the above structure, when the detection device needs to be fixed to the tank, the fixing base 101 is placed close to the flange end of the tank. For ease of connection and sealing, the tank generally has a flange at the inlet. Pulling one of the sliding rods 102 causes the sliding rod 102 to drive the linkage gear 105 to rotate, and through the linkage gear 105, it drives the other sliding rod 102 to slide in the opposite direction. The two sliding rods 102 slide in opposite directions, increasing the distance between the locking blocks 104 on the two sliding rods 102. Two clamping blocks 104 are placed on the lower side of both ends of the flange, so that the flange is between the clamping blocks 104 and the sliding rod 102. Rotating the threaded rod 103, since the threaded rod 103 is threadedly connected to the sliding rod 102, the threaded rod 103 can drive the clamping blocks 104 to move closer to the sliding rod 102 as the threaded rod 103 rotates. After the clamping blocks 104 come into contact with the flange, the flange is fixed between the clamping blocks 104 and the sliding rod 102 by tightening the threaded rod 103, thereby realizing the fixation of this detection device to the tank.

[0025] See Figure 5 and Figure 6 The linkage gear 105 is also provided with an anti-rotation device on one side to limit its rotation. The anti-rotation device includes an anti-rotation plate 107 that can mesh with the linkage gear 105. The end of the anti-rotation plate 107 is provided with gear teeth that can mesh with the linkage gear 105. The anti-rotation plate 107 is slidably connected to the anti-rotation seat 106 that is fixed to the fixed base 101. The anti-rotation seat 106 has a groove from one side close to the linkage gear 105 to the other side, and the anti-rotation plate 107 is disposed in the groove. The anti-rotation seat 106 is provided with an anti-rotation drive device that drives the anti-rotation plate 107 to slide left and right. When the anti-rotation plate 107 meshes with the linkage gear 105, it can prevent the linkage gear 105 from rotating.

[0026] Those skilled in the art can use a cylinder or electric cylinder as an anti-rotation drive device to control the anti-rotation plate 107 to slide relative to the anti-rotation seat 106.

[0027] The cylinder requires an additional air source to operate, while the electric cylinder is expensive and heavy. To simplify the structure, an alternative embodiment of the anti-rotation drive device is provided. The anti-rotation drive device includes an adjusting rod 108 that controls the movement of the anti-rotation plate 107. One end of the anti-rotation plate 107 has teeth that can mesh with the linkage gear 105. The middle part of the anti-rotation plate 107 is slidably connected to the anti-rotation seat 106. The other end of the anti-rotation plate 107 has an adjusting rod 108 that is rotatably connected to it. The adjusting rod 108 is threadedly connected to the anti-rotation seat 106. The end of the anti-rotation plate 107 has a T-slot, and the end of the adjusting rod 108 has a boss that mates with the T-slot, so that the adjusting rod 108 can rotate relative to the anti-rotation plate 107. The middle part of the adjusting rod 108 is threadedly connected to the anti-rotation seat 106, and the other end of the adjusting rod 108 extends to the outside of the anti-rotation seat 106.

[0028] With the above structure, after the detection device is fixed to the tank, rotating the adjusting rod 108 causes it to move closer to the linkage gear 105 due to its threaded connection with the anti-rotation seat 106. Since the anti-rotation plate 107 is slidably connected to the anti-rotation seat 106, the adjusting rod 108 can drive the anti-rotation plate 107 closer to the linkage gear 105. When the anti-rotation plate 107 meshes with the linkage gear 105, the linkage gear 105 cannot rotate under the restriction of the anti-rotation plate 107. At this time, since the sliding rod 102 meshes with the linkage gear 105 and the linkage gear 105 cannot rotate, the sliding rod 102 cannot slide relative to the fixed base 101. The positions of the sliding rod 102 and the clamping block 104 are limited, ensuring the reliable fixation of the clamping block 104 relative to the flange.

[0029] This invention utilizes a fixing device that is fixed to the tank body, and adopts an inverted method to inspect the inside of the tank. The fixing device is fixed to the tank flange, and a lifting base that slides up and down on the lifting rod drives the rotating inspection device to inspect the length and width dimensions at different heights inside the tank. This avoids the problem of having to place the inspection device inside the tank during inspection, and improves the efficiency of the inspection work.

[0030] 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.
