Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for temperature measurement in silos, specifically to a device for detecting the tensile strength of temperature measuring cables for cylindrical silos. Background Technology

[0002] In the grain storage industry, cylindrical silos are commonly used grain storage facilities. Temperature-sensing cables are used to monitor the temperature of the grain inside the silo in real time to ensure grain storage safety. These cables are typically laid along the height of the cylindrical silo, with one end fixed to the top and the other end hanging down to the bottom.

[0003] In related technologies, during the process of grain entering and leaving the warehouse, the grain will exert forces such as compression and friction on the temperature measuring cable; at the same time, as the storage time goes by, the aging of the temperature measuring cable itself, changes in its own weight, and fluctuations in temperature and humidity inside the warehouse will all cause changes in its stress state.

[0004] Currently, the industry lacks a dedicated testing device for the stress state of temperature measuring cables inside cylindrical silos. Most rely on manual, periodic inspections to observe the cables for obvious deformation or damage. However, manual inspections cannot obtain internal stress data, making it difficult to predict cracking risks in advance. Furthermore, the large size of cylindrical silos poses safety hazards for manual inspections, resulting in low testing efficiency. To address these issues, a tensile testing device for temperature measuring cables in cylindrical silos is proposed. Utility Model Content

[0005] In view of this, the present invention provides a tensile testing device for temperature measuring cables in cylindrical silos. The present invention clamps the temperature measuring cable with two arc-shaped sleeves of a clamping assembly, and then suspends the clamping assembly with a sling connected and fixed thereto. The temperature measuring cable is then suspended by the clamping assembly and connected to the detection end of the tensile tester via a lifting ring and connecting cable. Thus, when the temperature measuring cable is affected by dynamic feeding, the stress data of the temperature measuring cable can be recorded, thereby reducing the frequency of manual periodic inspection of the cable. This allows for convenient acquisition of the stress data of the temperature measuring cable, early prediction of crack risk, and improved inspection safety and testing efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a tensile testing device for a temperature measuring cable in a cylindrical silo. The device includes a support plate installed at the top of the cylindrical silo, with multiple openings on the support plate. A temperature measuring cable is suspended from each opening into the cylindrical silo. A protective sleeve is installed inside each opening, and the temperature measuring cable is placed inside the protective sleeve. A clamping assembly is installed at the upper part of each temperature measuring cable, and a sling is installed on each clamping assembly. The sling passes axially through the protective sleeve. A detachable lifting ring is installed at the upper part of the sling, and a connecting cable is installed above the lifting ring. A tensile detector is installed above the connecting cable, and a limit component is installed above the tensile detector. A communication component is installed adjacent to the limit component.

[0007] The protective sleeve includes two arc-shaped clamps for holding temperature measuring cables. The arc-shaped clamps are used to hold temperature measuring cables of different sizes. Each arc-shaped clamp has a pair of threaded holes at its end for inserting bolts. The bolts tighten the protective sleeve to fix it to the surface of the temperature measuring cable. The two arc-shaped clamps are connected in an adjustable manner by bolts. Each arc-shaped clamp has a protective groove on its inner arc surface for installing an anti-slip sleeve. The anti-slip sleeve is fixedly installed in the protective groove to increase the friction between the inner arc surface of the arc-shaped clamp and the surface of the temperature measuring cable.

[0008] Each arc-shaped jacket has a connecting block on its outer arc surface. The connecting block is used to open a screw hole. Each connecting block has a through screw hole. The screw hole is used to insert the two ends of the bottom of the sling. The sling is inverted U-shaped. The two ends of the bottom of the sling are fixed with a nut through the screw hole. The nut is used to fix the end of the sling that passes through the screw hole.

[0009] The lifting ring is G-shaped, with a rounded corner at the bottom of the opening to prevent excessive swaying of the top of the sling. A threaded lock is provided outside the opening to prevent the opening end of the lifting ring from moving.

[0010] The connecting cable includes a rope whose lower part is connected to the top of the lifting ring. The rope is used to connect the hanging lug to the lifting ring. The upper part of the rope is provided with a hanging lug, which is used to facilitate the rope to be hung on the detection groove of the tension detector. The hanging lug is connected to the detection end of the tension detector.

[0011] The limiting component includes a support plate connected to the inner top wall of the cylindrical hopper. The support plate is used to install the limiting plate and also to fix the upper part of the tensile detector. A pair of limiting plates are provided at the bottom of the support plate. The limiting plates are used to prevent the tensile detector from shaking and to protect the tensile detector from dust. The tensile detector is located between the two limiting plates.

[0012] The communication component includes a connecting plate connected to the support plate, which connects the power supply module to the top wall inside the cylindrical hopper. The power supply module is located at the bottom of the connecting plate and supplies power to the electrical components on the tensile testing device. A wireless transmission module is connected to the bottom of the power supply module via a partition and is used to transmit the data measured by the tensile detector. The power supply module is electrically connected to the input terminal of the tensile detector.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The temperature measuring cable is clamped by two arc-shaped sleeves of the clamping assembly, and then the clamping assembly is suspended by the sling connected to it. The temperature measuring cable is then suspended by the clamping assembly and then connected to the detection end of the tensile detector through the lifting ring and connecting cable. In this way, when the temperature measuring cable is affected by dynamic feeding, the stress data of the temperature measuring cable can be recorded. This reduces the frequency of manual periodic inspection of the cable, makes it convenient to obtain the stress data of the temperature measuring cable, can predict the risk of cracking in advance, and improves the safety and detection efficiency of the inspection.

[0014] 2. The arc-shaped sleeve is used to clamp temperature measuring cables of different sizes, and the threaded hole is used to insert bolts, so that the protective sleeve is fixed to the surface of the temperature measuring cable by the tightening of the bolts.

The anti-slip sleeve is used to increase the friction between the inner arc surface of the arc-shaped jacket and the outer sheath of the temperature measuring cable. Attached Figure Description
