Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grain pile inspection machinery technology, specifically relating to an anti-fall-off grain pile height measuring device. Background Technology
[0002] Modern grain storage warehouses, when full of grain, typically have a grain pile height of 6-10 meters. To ensure accurate grain quantity measurement, it is necessary to check various data points, including the grain pile height. Currently used connected grain pile height gauges usually consist of four rods connected by screws. During the retraction of the height gauge after measuring the grain pile height, due to the nature of the screw connection, the bottom rods can easily detach and fall into the grain surface if not handled carefully. Once the height gauge rods detach, it not only affects the efficiency of the measurement work but may also lead to the loss of the height gauge components, increasing equipment maintenance costs. Furthermore, it may cause unnecessary disturbance to the grain pile, affecting the stability of grain storage. Therefore, it is necessary to improve the system to solve these problems. Utility Model Content
[0003] This utility model provides an anti-fall-off grain pile height measuring device to solve at least one of the above-mentioned technical problems.
[0004] The technical solution adopted by this utility model is as follows: a grain pile height measuring device with anti-fall-off function, comprising a head measuring rod and a body measuring rod that can be connected as one piece. The head measuring rod is a hollow tube including a pointed section and a connecting section. The body measuring rod is a hollow tube including an insertion section and a connecting section. The outer diameter of the insertion section is the same as the inner diameter of the connecting section, so that the insertion section extends into the connecting section to connect the head measuring rod and the body measuring rod. A head anti-fall-off ring is fixedly connected to the inner side of the head measuring rod. A head anti-fall-off rope is connected to the head anti-fall-off ring. The head anti-fall-off rope passes through the inner side of the head measuring rod and the body measuring rod and extends out from the connecting section.
[0005] In a preferred embodiment, the device further includes a body anti-detachment ring, the outer diameter of which is larger than the inner diameter of the insertion section, and a body anti-detachment rope connected to the body anti-detachment ring, the body anti-detachment rope passing through the inner side of the body height measuring rod and extending out from the connecting section.
[0006] In a preferred embodiment, either the anti-slip ring or the insertion section has a connecting groove, and the other has a connecting protrusion, so as to restrict the rotation of the anti-slip ring by the cooperation of the connecting groove and the connecting protrusion.
[0007] In a preferred embodiment, the device further includes an end fixing ring connected to the end of the body height measuring rod connecting section. The outer diameter of the end fixing ring is larger than the outer diameter of the connecting section. The end fixing ring has a fixing rod, and the head anti-slip rope and the body anti-slip rope are connected to the fixing rod.
[0008] In a preferred embodiment, either the end height measuring rod connecting section or the end fixing ring has a mating groove, and the other has a mating protrusion, so as to restrict the rotation of the end fixing ring by means of the mating groove and the mating protrusion.
[0009] In a preferred embodiment, the ends of the head anti-slip rope and the body anti-slip rope have connecting hooks.
[0010] In a preferred embodiment, the insertion segment has a variable diameter portion, and the connecting segment has a connecting portion that mates with the variable diameter portion.
[0011] In a preferred embodiment, the insertion segment is threadedly connected to the connecting segment.
[0012] In a preferred embodiment, the lengths of the head height measuring rod and the body height measuring rod are whole meters, and scale lines are formed on the outer surfaces of the head height measuring rod and the body height measuring rod.
[0013] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0014] 1. As a preferred embodiment of this utility model, the anti-detachment grain pile height measuring device is equipped with a head anti-detachment ring and a head anti-detachment rope, which connect the head measuring rod and all the body measuring rods in series. When a section of the measuring rod falls off, all the measuring rods can be pulled out together by pulling the head anti-detachment rope, which reduces the time spent searching for the fallen rods, makes the measurement work more efficient, and ensures the timeliness of data measurement in grain storage management.
[0015] 2. As a preferred embodiment of this utility model, when a section of the height measuring pole falls off, during the upward pulling process using the head anti-fall rope, the fallen height measuring pole may be at a certain angle to the remaining height measuring pole due to uneven force. If the head anti-fall rope is forcibly pulled, it may break. However, by using the body anti-fall ring and body anti-fall rope, the height measuring pole at a certain angle can be straightened during the pulling process by simultaneously pulling the head anti-fall rope and the body anti-fall rope, thus avoiding the problem of the anti-fall rope breaking during the pulling process.
[0016] In addition, the rotation of the anti-slip ring can be restricted by the cooperation of the connecting groove and the connecting protrusion, ensuring that it always stays in the designed position and avoiding the problem of the anti-slip rope breaking due to the rotation of the anti-slip ring during the traction process.
[0017] 3. As a preferred embodiment of this utility model, by setting a fixed rod, the head anti-slip rope and the body anti-slip rope are uniformly fixed on the fixed rod. Through the traction of the anti-slip rope, the circumferential rotation between the height measuring rods can be reduced or avoided, thereby preventing the height measuring rods from loosening or falling off and improving the reliability of anti-slip.
[0018] In addition, the mating groove and mating protrusion restrict the rotation of the end fixing ring and form a mating with the body fixing ring, further restricting the circumferential rotation between the height measuring rods, which can effectively prevent the connection parts from loosening.
[0019] 4. As a preferred embodiment of this utility model, by setting connecting hooks at the ends of the head anti-slip rope and the body anti-slip rope, the purpose of quick connection and disassembly is achieved, and the hooks replace the traditional knots, avoiding the rope ends from breaking due to repeated friction.
[0020] 5. In a preferred embodiment of this utility model, a variable diameter part is provided on the insertion section and a connecting part is provided on the connecting section. By setting the outer diameter of the variable diameter part to be smaller than the inner diameter of the connecting part, the variable diameter part can be easily inserted into the connecting part, thereby achieving the purpose of mutual connection between the two.
[0021] In addition, by setting threaded connections on the insertion section and the connecting section, the reliability and fastening force of the insertion section and the connecting section are improved, and it is easy to disassemble and reuse.
[0022] Furthermore, by setting the lengths of the head and body height measuring rods to whole meters and adding graduation lines, the combination of whole meters and clear graduation lines can reduce calculation errors, improve measurement efficiency and accuracy, and achieve precise measurement.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0039] Example 1
[0040] like Figure 1 and Figure 2 As shown, a grain pile height measuring device designed to prevent detachment.
[0041] The system includes a head height measuring rod and a body height measuring rod that can be connected as one unit. The head height measuring rod is a hollow tube consisting of a pointed section 1 and a connecting section 2. The pointed section 1 reduces the resistance of the grain to the insertion of the height measuring rod into the grain pile, making the insertion process easier and thus reducing labor intensity and improving work efficiency. The body height measuring rod is also a hollow tube consisting of an insertion section 3 and a connecting section 2. The outer diameter of the insertion section 3 is the same as the inner diameter of the connecting section 2, allowing the insertion section 3 to extend into the connecting section 2 to connect the head and body height measuring rods. The purpose of having multiple height measuring rods is to reduce their length, making them easier to carry. Furthermore, each height measuring rod can be inserted into the grain pile individually, facilitating operation and reducing the difficulty of operation, thus enabling a single person to operate the system. This design allows for easy operation and further improves work efficiency. During use, a head anti-detachment ring 11 is fixedly connected to the inner side of the head height measuring rod, and a head anti-detachment rope 12 is connected to the head anti-detachment ring 11. The head anti-detachment rope 12 passes through the inner side of the head height measuring rod and the body height measuring rod and extends out from the connecting section 22. When extending the height measuring device, the head anti-detachment rope 12 passes through the body height measuring rod before connecting the head height measuring rod and the body height measuring rod. This connects the head height measuring rod and connects all the body height measuring rods in series. When a section of the height measuring rod falls off, all the height measuring rods can be pulled out together by pulling the head anti-detachment rope 12 and fall into the grain pile. This reduces the time spent searching for the fallen rods and makes the measurement work more efficient.
[0042] Example 2
[0043] like Figure 3 and Figure 4As shown, a type of anti-detachment grain pile height measuring device, differing from Embodiment 1, has an outer diameter of the anti-detachment ring 31 larger than the inner diameter of the insertion section 3. An anti-detachment rope 32 is connected to the anti-detachment ring 31, extending from the connecting section 2 through the inner side of the height measuring rod. An anti-detachment ring 31 is provided at one end (near the connecting end) of each section of the height measuring rod. One end of the anti-detachment rope 32 is securely tied to the anti-detachment ring 31. When a section of the height measuring rod detaches, the head anti-detachment rope is used. During the upward pulling process, uneven force may cause the detached height measuring pole to form an angle with the remaining height measuring pole. If the head anti-detachment rope 12 is pulled upwards alone, it may break due to angle jamming or friction. Therefore, the head anti-detachment rope 12 and the body anti-detachment rope 32 can be pulled simultaneously. During the pulling, the tension of the body anti-detachment rope 32 will force the tilted detached section to gradually straighten and align with the remaining section, thus preventing the head anti-detachment rope 12 from breaking. The anti-detachment device prevents the height measuring rod from breaking during retraction. Even if the bottom rod breaks during retraction, the operator can easily pull it out using the head anti-detachment rope 12 and body anti-detachment rope 32 simultaneously. This avoids the loss of height measuring device components, reduces equipment maintenance costs, and reduces the time spent searching for the detached rod, allowing for more efficient measurement and ensuring the timeliness of data measurement in grain storage management. Simultaneously, either the body anti-detachment ring 31 or the insertion section 3 has a connecting groove 311, and the other has a connecting protrusion 312. The cooperation of the connecting groove 311 and the connecting protrusion 312 restricts the rotation of the body anti-detachment ring 31. In use, by rotating the insertion section 3, the connecting groove 311 engages the connecting protrusion 3123, causing the body anti-detachment ring 31 to be tightly engaged within the insertion section 3. This prevents the body anti-detachment ring 31 from rotating unexpectedly due to external force or vibration, ensuring it remains in its designed position and avoiding breakage of the anti-detachment rope due to rotation of the anti-detachment ring during traction.
[0044] Meanwhile, by setting connecting hooks 321 at the ends of the head anti-slip rope 12 and the body anti-slip rope 32, the height measuring device can be quickly connected and disassembled when used or stored. The connecting hooks 321 have locks to prevent accidental disengagement, which is safer than directly tying the rope. If the anti-slip rope is worn, it can be replaced simply by unhooking the hook, without disassembling the entire structure.
[0045] Furthermore, by setting a variable diameter part 34 on the insertion section 3 and a connecting part 22 on the connecting section 2, and by setting the outer diameter of the variable diameter part 34 to be smaller than the inner diameter of the connecting part 22, the variable diameter part 34 can be easily inserted into the connecting part 22, ensuring smooth assembly and alignment. Moreover, the variable diameter part 34 acts as a "guide head," allowing the inner diameter of the connecting part 22 to closely fit the outer diameter of the variable diameter part 34, improving reliability and achieving the purpose of mutual connection between the two. At the same time, by setting a threaded connection on the insertion section 3 and the connecting section 2, the purpose of fastening the connection is achieved through the cooperation of internal and external threads. The threaded connection can be tightened and loosened multiple times, facilitating maintenance and replacement of parts.
[0046] Example 3
[0047] like Figure 5 and Figure 6 As shown, a grain pile height measuring device with anti-detachment feature, differing from Embodiment 1, has an end fixing ring 21 connected to the end section 2 of the measuring rod. The outer diameter of the end fixing ring 21 is larger than the outer diameter of the connecting section 2. The end fixing ring 21 has a fixing rod 211. In use, the anti-detachment ropes of the head and body are uniformly fixed to the fixing rod 211. Through the traction of the anti-detachment ropes, the measuring rods can be physically tightened together, reducing or avoiding circumferential rotation between the measuring rods and thus preventing loosening, enhancing the overall anti-detachment effect. Furthermore, the fixing rod 211 serves as a common anchor point, allowing the tension of the two anti-detachment ropes to be increased. The stress is transmitted more evenly to the end of the height measuring rod, reducing local stress concentration, enhancing the overall anti-detachment effect, and improving the reliability of the anti-detachment. At the same time, either the end height measuring rod connecting section 2 or the end fixing ring 21 has a mating groove 212, and the other has a mating protrusion 213. When in use, by rotating the end fixing ring 21, the mating protrusion 213 is engaged into the mating groove 212, thereby restricting the rotation of the end fixing ring 21. This prevents the anti-detachment ring from rotating unexpectedly due to external force or vibration, ensuring that it always remains in the designed position, thereby further restricting the circumferential rotation between the height measuring rods and avoiding the risk of loosening or falling off.
[0048] In addition, such as Figure 6 As shown, the lengths of the head and body height measuring rods are whole meters. Scale lines 23 are formed on the outer surfaces of the head and body height measuring rods. By using whole meters in conjunction with clear scale lines 23, calculation errors can be reduced. Furthermore, segmenting into whole meters can avoid the superposition of deviations during continuous measurements, reducing cumulative errors and improving measurement efficiency and accuracy.

[0050] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
[0051] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
