Description

Technical Field

[0001] The utility model belongs to the field of steel bar tensioning force detection equipment, and in particular relates to a building steel bar tensioning force detection machine. Background Art

[0002] The building steel bar tension tester is a device used to test and evaluate the tension performance of steel bars in building structures. The tester generally clamps the two ends of the steel bar, uses a motor to stretch it, and uses a load sensor connected to the motor to detect the tension value of the steel bar. It quantitatively evaluates the tension performance of the steel bar. When performing outdoor engineering operations such as bridges and high-rise buildings, threaded steel bars with good tensile properties are usually used in large quantities. Therefore, there is often a need for outdoor sampling and testing of threaded steel bars.

[0003] However, existing threaded steel bar tension testing machines usually lack heat dissipation functions. When faced with extremely high outdoor temperatures, heat is easily accumulated inside the testing equipment, thereby reducing the performance of internal motors and electronic components, and further damaging the service life of the testing equipment.

[0004] Therefore, in view of the problem that the above-mentioned steel bar tension force testing machine lacks a heat dissipation device, it is easy to generate heat accumulation inside the testing equipment when facing extremely high temperature weather in summer, which in turn has an adverse effect on the performance of internal motors and electronic components and damages the service life of the equipment. A construction steel bar tension force testing machine is developed. By wrapping a device that uses circulating water cooling to dissipate heat around the base of the steel bar tension force testing machine, which is most prone to heat up, the temperature of the motor and electronic components in the base during operation is reduced, thereby improving the service life of the equipment. Utility Model Content

[0005] In order to overcome the lack of heat dissipation device in the steel bar tension tester, heat is easily accumulated inside when facing extremely high temperature weather in summer, which damages the performance of internal electronic components and motors and reduces the service life of the equipment.

[0006] The technical solution of the utility model is: a building steel bar tension detection machine, including a detection machine body, a rotating motor, a steel bar fixing structure, a water circulation component, a spiral water pipe, a heat dissipation structure, and a heat dissipation fin structure. The detection machine body is a frame-shaped detection structure with a tension motor and a load sensor inside, and the motor sensor and other heat-prone components of the detection machine body are concentrated on the protrusions of the lower surface. A rotating motor is arranged in the detection machine body frame, and a steel bar fixing structure is arranged at the end of the transmission element of the rotating motor. A water circulation component is arranged below the detection machine body, and a spiral water pipe for constructing a water channel is connected to the side of the water circulation component. A heat dissipation structure for cooling by a fan is arranged inside the water circulation component, and a heat dissipation fin structure is arranged outside the water circulation component.

[0007] Preferably, the rotating motor is combined with the steel bar fixing structure to facilitate the adaptive fixing of the threaded steel bar by using the rotating screw hole of the motor, thereby saving the labor cost when installing the steel bar. The water circulation component performs circulating heat exchange through the water cavity and the cold water tank that wrap the heat dissipation part of the detection machine, so as to facilitate the rapid heat dissipation of the core heating part of the detection machine. The spiral water pipe uses the centrifugal force of the rotating water flow to make the water flow fit more closely to the water pipe wall, thereby improving the cooling effect of the liquid. The heat dissipation structure uses a fan to cool the water inside the water tank that is not easily in contact with the air, thereby improving the cooling effect. The heat dissipation fin structure increases the contact area with the air through the concave-convex outer surface to increase the heat dissipation speed.

[0008] Preferably, a rotating motor is fixedly connected to the upper end of the detection machine body frame, and another rotating motor is fixedly connected to the end of the transmission element of the internal stretching motor at the lower end of the detection machine body frame. The threaded steel bars are automatically screwed and fixed by rotating the fixing screw holes through the transmission element of the rotating motor, thereby saving the labor cost when screwing and fixing the threaded steel bars.

[0009] Preferably, the steel bar fixing structure includes a fixing head and a fixing screw hole. The end of the transmission element of the rotating motor is fixedly connected to the fixing head. Fixing screw holes that are compatible with the threaded steel bars are opened on the opposite sides of the two fixing heads. The fixing screw holes that are compatible with the threads of the threaded steel bars processed by the thread making machine can be screwed and fixed using the processed threads, thereby increasing the firmness of the threaded steel bars.

[0010] Preferably, the water circulation component includes a cooling water chamber, a cooling water storage tank, and a water inlet and outlet. The outer side of the raised portion on the lower surface of the detection machine body is wrapped with a cooling water chamber with a matching shape and containing a water pump. A cooling water storage tank is provided on the side of the cooling water chamber. A pair of water inlets and outlets are provided on the sides of the cooling water chamber and the cooling water storage tank. Circulating heat exchange is carried out through the cooling water chamber and the cooling water storage tank that wrap the heating part of the detection machine, which facilitates rapid heat dissipation of the core part of the detection machine, thereby reducing the ambient temperature of the motor and electronic components when they are working, thereby increasing the service life of the detection machine.

[0011] Preferably, a spiral water pipe is a hard spiral metal pipe, and both ends of the spiral water pipe are respectively connected to the inlet and outlet of the cooling water chamber and the cooling water storage tank to jointly construct a circulating water circuit. The bending and winding of the spiral water pipe makes the actual length of the water pipe longer than that of a straight pipe. Therefore, water can contact more of the inner surface of the pipe when flowing through the spiral water pipe. At the same time, the rotating water flow causes eddy motion, so that the water source fits more closely to the inner surface of the pipe due to the rotating centrifugal force, thereby jointly improving the heat dissipation speed, and the heat-dissipated water flow is mixed with the non-heat-dissipated water flow through rotating stirring, so that the heat is evenly distributed in the water flow, and the cooling of the liquid is more uniform, thereby improving the cooling effect of water cooling.

[0012] Preferably, the heat dissipation structure includes a heat dissipation duct and a heat dissipation fan. A heat dissipation duct is opened on the side of the cooling water storage box, and heat dissipation fans are embedded and installed at both ends of the heat dissipation duct. The heat dissipation duct allows the water source inside the cooling water storage box, which is originally difficult to exchange heat with the air, to come into contact with the air, and is cooled in conjunction with the heat dissipation fan, thereby improving the cooling effect of the cooling water and thus improving the refrigeration efficiency of the water cooling.

[0013] Preferably, a number of concave-convex heat dissipation fin structures are arranged inside the heat dissipation duct and outside the cooling water storage box. The concave-convex outer surface of the heat dissipation fin structure increases the contact area with the air, thereby increasing the heat exchange rate between the cooling water and the air, and further improving the refrigeration efficiency of the water cooling.

[0014] Beneficial effects of the utility model:

[0015] 1. The rotating motor cooperates with the steel bar fixing structure to facilitate the adaptive fixing of the threaded steel bar by using the rotating screw hole of the motor, saving the labor cost when installing the steel bar. The water circulation component performs circulating heat exchange through the water cavity and cold water tank that wrap the heat dissipation part of the detection machine, which is convenient for rapid heat dissipation of the core heating part of the detection machine. The spiral water pipe makes the water flow fit closer to the water pipe wall through the centrifugal force of the rotating water flow, thereby improving the cooling effect of the liquid. The heat dissipation structure uses a fan to cool the water inside the water tank that is not easily in contact with the air, thereby improving the cooling effect. The heat dissipation fin structure increases the contact area with the air through the concave and convex outer surface to increase the heat dissipation speed.

[0016] 2. The threaded steel bars are automatically fixed by rotating the motor in conjunction with the fixing screw holes that match the shape of the threaded steel bars, saving the labor cost when installing the threaded steel bars.

[0017] 3. Use the cooling water storage tank to connect the cooling water chamber, and quickly cool the cooling water and the heat dissipation part through water circulation to exchange heat, thereby lowering the operating temperature of the equipment, reducing component damage, and increasing the service life of the equipment.

[0018] 4. Use fans and cooling fins, in conjunction with the central air duct, to quickly dissipate heat inside and outside the cooling water storage tank, increase the water cooling speed, and thus enhance the cooling effect of water cooling.

[0019] 5. The eddy current motion caused by the spiral pipe makes the water source fit closer to the inner wall of the pipe due to the centrifugal force, thereby increasing the heat dissipation speed of the water source and thus improving the cooling efficiency of the water cooling.

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] See also Figure 1-2 The utility model provides an embodiment: a building steel bar tension tester, comprising a tester body 1, a rotating motor 2, a steel bar fixing structure 3, a water circulation component 4, a spiral water pipe 5, a heat dissipation structure 6, and a heat dissipation fin structure 7. The tester body 1 is a frame-shaped test structure with a tension motor and a load sensor inside, and the motor sensor and other heat-prone components of the tester body 1 are concentrated at the protrusions on the lower surface. The tester body 1 is provided with a rotating motor 2 in the frame, and the end of the transmission element of the rotating motor 2 is provided with a steel bar fixing structure 3. A water circulation component 4 is provided below the tester body 1, and a spiral water pipe 5 for constructing a waterway is connected to the side of the water circulation component 4. A heat dissipation structure 6 for cooling by a fan is provided inside the water circulation component 4, and a heat dissipation fin structure 7 is provided outside the water circulation component 4. By wrapping a device for dissipating heat by circulating water cooling around the base of the steel bar tension tester, which is most prone to heat, the temperature of the motor and electronic components in the base during operation is reduced, thereby improving the service life of the equipment.

[0029] See also Figure 3In this embodiment, a rotating motor 2 is fixedly connected to the upper frame-shaped end of the detection machine body 1, and another rotating motor 2 is fixedly connected to the end of the transmission element of the internal stretching motor at the lower frame-shaped end of the detection machine body 1. The steel bar fixing structure 3 includes a fixing head 301 and a fixing screw hole 302. The end of the transmission element of the rotating motor 2 is fixedly connected to the fixing head 301. The opposite sides of the two fixing heads 301 are provided with fixing screw holes 302 that are compatible with the threaded steel bars. The threaded steel bars are automatically screwed and fixed by rotating the fixing screw holes 302 through the transmission element of the rotating motor 2, which saves the labor cost when screwing and fixing the threaded steel bars. The fixing screw holes 302 that are compatible with the threads of the threaded steel bars processed by the thread making machine can be used for screwing and fixing, thereby increasing the firmness of the threaded steel bars.

[0030] See also Figure 4-6In this embodiment, the water circulation component 4 includes a cooling water chamber 401, a cooling water storage tank 402, and a water inlet and outlet 403. The outer side of the raised portion on the lower surface of the detection machine body 1 is wrapped with a cooling water chamber 401 with a shape adaptation and containing a water pump. The cooling water storage tank 402 is arranged on the side of the cooling water chamber 401. The cooling water chamber 401 and the cooling water storage tank 402 are both provided with a pair of water inlets and outlets 403, and a spiral water pipe 5. The spiral water pipe 5 is a hard spiral metal pipe. The two ends of the spiral water pipe 5 are respectively connected to the cooling water chamber 401 and The water inlet and outlet 403 of the cooling water storage tank 402 jointly construct a circulating water circuit, and the heat dissipation structure 6 includes a heat dissipation duct 601 and a heat dissipation fan 602. The heat dissipation duct 601 is opened through the side of the cooling water storage tank 402, and the heat dissipation fans 602 are embedded and installed at both ends of the heat dissipation duct 601. A plurality of concave and convex heat dissipation fin structures 7 are arranged inside the heat dissipation duct 601 and outside the cooling water storage tank 402. The cooling water chamber 401 of the heating part of the package inspection machine and the cooling water storage tank 402 are used for circulating heat exchange. The invention can quickly dissipate heat from the core part of the detection machine, thereby reducing the ambient temperature of the motor and electronic components when they are working, thereby increasing the service life of the detection machine. The bending and winding of the spiral water pipe 5 makes the actual length of the water pipe longer than that of the straight pipe. Therefore, when water flows through the spiral water pipe 5, it can contact more inner surfaces of the pipe. At the same time, the rotating water flow causes eddy current motion, so that the water source fits more closely to the inner surface of the pipe due to the rotating centrifugal force, thereby jointly increasing the heat dissipation speed. The heat-dissipated water flow is mixed with the non-heat-dissipated water flow through rotating stirring, so that the heat is evenly distributed in the water flow, and the cooling of the liquid is more uniform, thereby improving the cooling effect of water cooling. The heat dissipation duct 601 allows the water source inside the cooling water storage box 402, which was originally difficult to exchange heat with the air, to contact the air, and is cooled in cooperation with the heat dissipation fan 602, thereby increasing the cooling effect of the cooling water, thereby increasing the cooling efficiency of the water cooling. The concave-convex outer surface of the heat dissipation fin structure 7 increases the contact area with the air, thereby increasing the heat exchange speed between the cooling water and the air, thereby increasing the cooling efficiency of the water cooling.

[0031] When working, first, select the threaded steel bars that need to be sampled and tested, use a thread making machine to process threads suitable for screwing into the fixing screw holes 302 at both ends of the threaded steel bars, and then place the processed threaded steel bars vertically on the fixing head 301 at the lower end of the frame of the detection machine body 1, so that the threads at the lower end of the threaded steel bars are aligned with the fixing screw holes 302, then hold the threaded steel bars, start the stretching motor inside the detection machine body 1, and make the transmission element of the motor push the threaded steel bars upward so that the upper end of the steel bars contact the fixing head 301 at the upper end of the frame of the detection machine body 1 and press and fix it, then start the two rotating motors 2, and use the threads on the inner side of the fixing screw holes 302 to fix the two ends of the threaded steel bars in the two fixing heads 301 respectively;

[0032] The detection machine body 1 uses the JITAI-5000N model, and then the tension motor inside the detection machine body 1 can be used to stretch the fixed steel bar for tension testing, and the internal load sensor uses the resistance value change caused by the small deformation of the internal strain gauge, and uses the bridge circuit to perform differential measurement, and compares the changes between different resistances to detect the strain size, and converts the resistance change into a voltage change, generating an electrical signal proportional to the tensile force, and the value of the tensile force is calculated by reverse calculation through the size of the electrical signal;

[0033] When the tensile test is performed in an outdoor high temperature environment, the water pump inside the cooling water chamber 401 starts to work, and the water in the cooling water chamber 401 that wraps the heating part of the detection machine body 1 is used to exchange heat with the detection machine body 1, and then the cooled water source is continuously pumped from the cooling water storage tank 402 to the cooling water chamber 401, and the heated water source in the cooling water chamber 401 is sent to the cooling water storage tank 402, and the water source inside the cooling water storage tank 402, which was originally difficult to exchange heat with the air, is allowed to contact with the air through the heat dissipation duct 601, and is cooled by the heat dissipation fan 602, and the contact area with the air is increased by the concave-convex outer surface of the heat dissipation fin structure 7, thereby increasing the heat exchange rate between the cooling water and the air, and jointly cooling the heated water source, and at the same time, the spiral water pipe 5 uses the centrifugal force of the rotating water flow to make the water flow fit the water pipe wall more closely, thereby improving the cooling effect of the liquid, and further improving the refrigeration effect of the water cooling, and the above-mentioned heat dissipation process is used to continuously and quickly dissipate the heat of the core heating part at the bottom of the detection machine body 1, reduce the damage of components running at high temperature, and increase the service life of the detection machine body 1.

[0034] Through the above steps, the water circulation component 4 performs circulating heat exchange through the water cavity and the cold water tank that wrap the heat dissipation part of the detection machine, which is convenient for quickly dissipating the heat of the core heat-generating part of the detection machine. The spiral water pipe 5 makes the water flow fit closer to the water pipe wall through the centrifugal force of the rotating water flow, thereby improving the cooling effect of the liquid. The heat dissipation structure 6 uses a fan to cool the water inside the water tank that is not easily in contact with the air, thereby improving the cooling effect. The heat dissipation fin structure 7 increases the contact area with the air through the concave-convex outer surface to increase the heat dissipation speed, thereby solving the problem that the steel bar tension tester lacks a heat dissipation device, and is prone to heat accumulation in the face of extremely high temperature weather in summer, which damages the performance of internal electronic components and motors, resulting in a reduction in the service life of the equipment.

[0035] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
