Description

Technical Field

[0001] The utility model relates to the technical field of wire tensile testing, in particular to a fixture for a wire tensile testing machine in a high-temperature environment. Background Technique

[0002] Steel wire ropes are mainly used in hoisting, traction and other occasions, and the working conditions are relatively harsh. During use, friction and wear, fatigue failure, local wire breakage and deformation will occur, reducing the tensile strength of the steel wire rope. To ensure the reliability of repeated use of the steel wire rope, it is necessary to conduct tensile tests on it in accordance with relevant national standards. The steel wire rope tensile testing machine is mainly applicable to various physical and mechanical property tests of steel wire ropes, and uses a tensile testing machine to conduct mechanical property tests such as tension, compression, bending, shearing, and peeling on the steel wire rope. The fixture of the tensile testing machine is an important part of the instrument.

[0003] In a steel wire rope tensile testing machine of Chinese utility model patent CN208705169U, it includes a base and a support plate.

[0022] Please refer to Figures 1 - 4 As shown, a technical solution provided by the present invention: a fixture for a wire tensile testing machine in a high-temperature environment, including a base 1. A machine shell 2 is fixedly arranged at the top end of the base 1. A heating component is fixedly arranged at the top end inside the machine shell 2. A rectangular block 3 is fixedly arranged on the left side of the top end of the base 1. A connecting column 4 is fixedly arranged in the middle of the top end of the rectangular block 3. A first fixed fixture block 5 is fixedly arranged at the top end of the connecting column 4. A first threaded hole 6 is opened on the left side of the top end of the machine shell 2. A first screw rod 7 is threadedly arranged inside the first threaded hole 6.

A heat-resistant clamping block 34 is movably arranged inside the clamping groove 9;

[0023] In this embodiment, through the setting of the machine shell 2, when the steel wire rope inside the machine shell 2 breaks, the generated debris can be isolated by the machine shell 2, thereby achieving the effect of preventing the surrounding detection personnel from being injured by the debris. Through the setting of the first screw rod 7 and the clamping block 8, when in use, rotate the first screw rod 7 to make the first screw rod 7 rotate inside the first threaded hole 6, driving the heat-resistant clamping block 34 at the bottom end to move towards the heat-resistant clamping block 34 at the top end of the connecting column 4, thereby achieving the effect of facilitating the fixation of one end of the steel wire rope. Through the setting of the heat-resistant clamping block 34, when the temperature inside the machine shell 2 is relatively high, it can prevent oxidation on the surface of the clamping block caused by high temperature. Finally, through the setting of the clamping block 8, when the heat-resistant clamping block 34 is damaged, the heat-resistant clamping block 34 can be taken out from the clamping groove 9 inside the clamping block 8, facilitating timely replacement, thereby achieving the effect of improving the heat resistance and service life of the clamping block inside the machine shell;

[0024] As Figure 2 and Figure 4 shown, a fixed block 10 is fixedly arranged on the right side of the top end of the base 1. A cylinder 11 is fixedly arranged inside the fixed block 10. A connecting rod 12 is fixedly arranged at one end of the cylinder 11. A tensile force detection device 13 is fixedly arranged at one end of the connecting rod 12. A fixed frame 14 is fixedly arranged on one side of the tensile force detection device 13. A fixed clamping block 15 is fixedly arranged at the bottom end inside the fixed frame 14. A second threaded hole 16 is opened at the top end of the fixed frame 14. A second screw rod 17 is threadedly arranged inside the second threaded hole 16. The bottom end of the second screw rod 17 is rotatably arranged with a movable clamping block 18 through a rotating shaft. A plurality of grooves 35 are opened on the top end of the base 1. Protrusions 36 are arranged on both sides of the bottom end of the machine shell 2. The grooves 35 are movably connected with the protrusions 36;

[0025] In this embodiment, through the settings of the fixed clamping block 15 and the movable clamping block 18, when it is necessary to pull the steel wire rope, the second screw rod 17 is rotated. The second screw rod 17 rotates inside the second threaded hole 16, causing the movable clamping block 18 to move towards the fixed clamping block 15, fixing the other end of the steel wire rope inside the fixing frame 14. Through the setting of the cylinder 11, when in use, it drives the connecting rod 12 to pull the fixing frame 14, thereby achieving the effect of detecting the tensile force of the steel wire rope. Finally, through the setting of the tensile force detection device 13, when in use, it can detect the change of the tensile force of the pulled steel wire rope in real time, thereby achieving the effect of facilitating the operator to observe and record. Through the setting of the convex block 36, when in use, the convex block 36 at the bottom end of the casing 2 is inserted into the groove 35 at the top end of the base 1, fixing the casing 2 at the top end of the base 1. When the steel wire rope inside the casing 1 breaks, the generated debris can be isolated by the casing 1, preventing the surrounding detection personnel from being injured by the debris. When the detection is completed, the casing 1 is pulled out from the top end of the base 2, facilitating the cleaning of the debris after the breakage of the internal steel wire rope, thereby achieving the effect of protecting the safety of the surrounding test personnel;

[0026] As Figure 1 , Figure 2 and Figure 3 shown, the heating component includes a fixing plate 19, a fixing column 20 and a heating wire 21. Fixing plates 19 are arranged on both sides at the top end inside the casing 2. A fixing column 20 is fixedly arranged on one side of the fixing plate 19, and a heating wire 21 is fixedly arranged on the surface of the fixing column 20. A temperature detection device 22 is fixedly arranged on the left side at the top end inside the casing 2. A first rotating block 23 is fixedly arranged at the top end of the first screw rod 7, and a second rotating block 24 is fixedly arranged at the top end of the second screw rod 17. A first connection hole 25 is opened in the middle of the front surface of the casing 2, and a second connection hole 26 is opened in the middle of the back surface of the casing 2;

[0027] In this embodiment, through the settings of the fixing plate 19, the fixing column 20 and the heating wire 21, when it is necessary to detect the tensile force detection condition of the steel wire rope in a high-temperature environment, the heating wire 21 is energized for heating, increasing the temperature inside the casing 2. Then, the temperature detection device 22 detects the change of the temperature inside the casing 2 in real time, thereby achieving the effect of simulating a high-temperature environment and facilitating the improvement of the accuracy of the tensile force detection of the steel wire rope. Through the settings of the first rotating block 23 and the second rotating block 24, when in use, the first rotating block 23 and the second rotating block 24 are rotated, thereby achieving the effect of facilitating the operator to rotate the first screw rod 7 and the second screw rod 17. Through the opening of the first connection hole 25 and the second connection hole 26, when in use, it is convenient for the steel wire rope to pass through the inside of the casing 2, thereby achieving the effect of performing tensile force detection on the steel wire rope inside the casing 2;

[0028] As Figure 1 and Figure 2As shown, on one side of the casing 2, an observation window 27 is fixedly arranged. On both sides of the top end of the clamping block 8, positioning columns 28 are arranged. A fixing sleeve 29 is movably arranged on the surface of the positioning column 28. The top end of the fixing sleeve 29 is fixedly connected to the inner top end of the casing 2. On the left side of the casing 2, a support column 30 is fixedly arranged. On the top end of the support column 30, a rectangular plate 31 is fixedly arranged. On one side of the rectangular plate 31, a display screen 32 is fixedly arranged. Below the display screen 32, a number of control buttons 33 are fixedly arranged;

[0029] In this embodiment, through the arrangement of the observation window 27, during use, the internal situation of the casing 2 can be observed through the observation window 27, thus achieving the effect of facilitating the operator's observation. Through the arrangement of the positioning column 28, when the first screw 7 rotates during use, the positioning column 28 is restricted inside the fixing sleeve 29 and can only move up and down inside the fixing sleeve 29, thus achieving the effect of preventing the first screw 7 from driving the clamping block 8 to rotate synchronously. Through the arrangement of the support column 30 and the rectangular plate 31, during use, the display screen 32 and the control buttons 33 can be fixed on the top end of the base 1. Then, through the arrangement of the display screen 32 and the control buttons 33, during use, the display screen 32 can display the specific values detected by the temperature detection device 22 and the tensile force detection device 13, and the control buttons 33 can control the temperature inside the casing 2 and the change of the pulling force, thus achieving the effect of facilitating the operator to control the overall device.

[0030] Working principle: through the setting of the casing 2, when the steel wire rope inside the casing 2 breaks, the generated debris can be isolated by the casing 2, thereby achieving the effect of preventing the surrounding inspection personnel from being accidentally injured by the debris. Through the setting of the first screw rod 7 and the clamping block 8, the first screw rod 7 is rotated during use to make the first screw rod 7 rotate inside the first threaded hole 6, driving the bottom end heat-resistant clamping block 34 to move toward the top end heat-resistant clamping block 34 of the connecting column 4, thereby achieving the effect of facilitating the fixing of one end of the steel wire rope. Through the setting of the heat-resistant clamping block 34, when the internal temperature of the casing 2 is high, it can prevent the high temperature from causing oxidation on the surface of the clamping block. Finally, through the setting of the clamping block 8, when the heat-resistant clamping block 34 is damaged, the heat-resistant clamping block 34 can be taken out from the internal card slot 9 of the clamping block 8, which is convenient for timely replacement. Thus, the effect of improving the heat resistance and service life of the clamping block inside the casing is achieved. At the same time, through the setting of the fixed clamping block 15 and the movable clamping block 18, when it is necessary to pull the wire rope, the second screw 17 is rotated, and the second screw 17 is rotated inside the second threaded hole 16, so that the movable clamping block 18 moves toward the fixed clamping block 15, so that the other end of the wire rope is fixed inside the fixed frame 14, and then through the setting of the cylinder 11, the connecting rod 12 is driven to pull the fixed frame 14 when in use, thereby achieving the effect of performing tension detection on the wire rope. Finally, through the setting of the tension detection device 13, the tension change of the pulling wire rope can be detected in real time when in use, thereby achieving the effect of facilitating the operator to observe and record. Through the setting of the protrusion 36, the protrusion at the bottom of the casing 2 is set when in use. 36 is inserted into the groove 35 at the top of the base 1, so that the casing 2 is fixed on the top of the base 1. When the wire rope inside the casing 1 breaks, the generated debris can be isolated by the casing 1 to prevent the surrounding test personnel from being accidentally injured by the debris. When the test is completed, the casing 1 is pulled away from the top of the base 2, which is convenient for cleaning the debris after the internal wire rope breaks, thereby achieving the effect of protecting the safety of the surrounding test personnel. Through the arrangement of the fixing plate 19, the fixing column 20 and the heating wire 21, when it is necessary to detect the tension test condition of the wire rope in a high temperature environment, the heating wire 21 is energized and heated to increase the internal temperature of the casing 2. The temperature detection device 22 detects the temperature change inside the casing 2 in real time, thereby simulating a high temperature environment and facilitating the improvement of the wire rope tension. The effect of detecting accuracy is achieved by setting the first rotating block 23 and the second rotating block 24. When in use, the first rotating block 23 and the second rotating block 24 are rotated, so as to achieve the effect of facilitating the operator to rotate the first screw 7 and the second screw 17. By opening the first connecting hole 25 and the second connecting hole 26, it is convenient for the wire rope to pass through the inside of the casing 2 when in use, so as to achieve the effect of making the wire rope perform tension detection inside the casing 2. By setting the observation window 27, the internal situation of the casing 2 can be observed through the observation window 27 when in use, so as to achieve the effect of facilitating observation by the operator. By setting the positioning column 28, when the first screw 7 is rotated during use, the positioning column 28 is restricted inside the fixing sleeve 29 and can only move up and down inside the fixing sleeve 29.Thus, the effect of preventing the first screw rod 7 from driving the clamping block 8 to rotate synchronously is achieved. Through the arrangement of the support column 30 and the rectangular plate 31, the display screen 32 and the control buttons 33 can be fixed to the top of the base 1 during use. Furthermore, through the arrangement of the display screen 32 and the control buttons 33, the display screen 32 can display the specific values detected by the temperature detection device 22 and the tensile force detection device 13 during use, and the control buttons 33 can control the temperature inside the machine housing 2 and the change in the pulling force, thereby achieving the effect of facilitating the operator to control the overall device.
