[0002] In the production process of precast concrete components, magnetic box holders are commonly used to fix the precast component production molds to the work platform. Before leaving the factory, these magnetic box holders generally undergo fatigue testing, which tests the maximum number of pull-out operations they can withstand.
[0003] In the existing technology, fatigue testing of magnetic box holders is generally carried out manually by using a pry bar to pull them out. The whole process is not only inefficient, but more importantly, the testers need to use their physical strength to pull them out, which is very physically demanding.
[0004] Therefore, how to construct a new fatigue detection device that can automatically perform the pulling operation without requiring the testing personnel to perform the pulling operation by human force is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation
[0023] The technical solutions of specific embodiments of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the teachings of the following embodiments are within the protection scope of this utility model.
[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.
[0025] like Figures 1 to 4 As shown, the fatigue testing device based on the magnetic box holder of this utility model adopts the following overall concept: the magnetic box holder is pressed and fixed on the pressing platform, and a driver is set up. Utilizing the characteristic that the output end of the driver can output linear reciprocating motion, after connecting the pull-out component to the output end, the switch end of the pressed magnetic box holder is clamped in the pull-out end. In this way, under the drive of the output end of the driver, the pull-out component can perform pull-out tests on the switch end repeatedly. The entire testing process does not require the testing personnel to operate online at all times, and the whole process is carried out automatically, with a very high degree of automation.
[0026] The following describes specific embodiments, still referring to the appendix. Figure 1 To be continued Figure 4 In this embodiment, the fatigue detection device based on the magnetic box holder includes: a frame 1, a driver 2, and a pulling member. The driver 2 is mounted on the frame 1 and has an output end 3 for outputting linear motion. The frame 1 has a clamping platform 4, which is used for placing the magnetic box holder 5 and can fix the position of the placed magnetic box holder 5. The pulling member has a pulling end 6, and the switch end 7 of the magnetic box holder 5 is snapped into the pulling end 6. The pulling member is also connected to the output end 3 of the driver 2 to realize the pulling operation of the switch end 7.
[0027] Specifically, in this embodiment, for the frame 1, in addition to setting the clamping platform 4, an installation platform 8 is also set above the clamping platform 4. The driver 2 is installed on the installation platform 8. At this time, the driver 2 is installed on the installation platform 8 with its output end 3 facing upward. Thus, the installation platform 8 and the clamping platform 4 are arranged vertically in the setting direction, and the clamping platform 4 and the installation platform 8 are also supported and connected by a vertical support beam 9, thereby improving the overall structural strength.
[0028] Regarding the bottom structure of the frame 1, in this embodiment, the frame 1 is further provided with a base plate 10 below the pressure platform 4. The base plate 10 and the pressure platform 4 have a vertical distance, and the base plate 10 and the pressure platform 4 are connected by a supporting vertical beam 22. With this arrangement, the vertical height of the pressure platform 4 can be effectively raised during testing, avoiding the need for the testing personnel to squat down and bend over to the maximum extent to perform the clamping and testing of the magnetic box holder due to the excessively low height.
[0029] In this embodiment, the frame 1 is constructed as an installation platform 8, a pressure platform 4, and a base plate 10 arranged vertically, so that the power mechanism is located on the top and the pulling mechanism is located on the bottom, and the pulling position is raised at the same time. The whole structure is expanded in the vertical direction, which effectively reduces the amount of horizontal area occupied, saves more floor space, and the overall vertical layout is orderly, compact and reasonable.
[0030] It should be noted that the driver 2 can be a pneumatic cylinder, a hydraulic cylinder, or a linear motor. In this embodiment, a hydraulic cylinder is preferred as the driver 2 because the hydraulic cylinder has a large pulling force, which can meet the pulling force required for the pulling operation.
[0031] In this embodiment, the pulling member is constructed in the following manner: the pulling member has an upper connecting part 11 and a lower connecting part 12, the output end 3 of the driver 2 is connected to the middle part of the upper connecting part 11, and the pulling end 6 is connected to the middle part of the lower connecting part 12.
[0032] Meanwhile, a first connecting rod 13 and a second connecting rod 14 are symmetrically arranged on both sides of the output end 3. The upper ends of the first connecting rod 13 and the second connecting rod 14 are respectively connected to the two ends of the upper connecting part 11, and the lower ends of the first connecting rod 13 and the second connecting rod 14 are respectively connected to the two ends of the lower connecting part 12. In this embodiment, the first connecting rod 13 and the second connecting rod 14 also serve as components of the pulling member, jointly realizing the pulling operation.
[0033] To maintain stable operation, the lower ends of the first connecting rod 13 and the second connecting rod 14 pass through the mounting platform 8 and are respectively connected to the two ends of the lower connecting part 12.
[0034] The pulling component of the above structure adopts a central connection method. For example, the output end 3 is connected to the middle of the upper connecting part 11, and the pulling end 6 is connected to the middle of the lower connecting part 12. The first connecting rod 13 and the second connecting rod 14 are symmetrically arranged on both sides of the output end 3. The overall layout is symmetrical, and the force distribution is also centrally transmitted and symmetrically distributed. The overall force is balanced. During the pulling process, especially during numerous pulling processes, the occurrence of swaying can be avoided as much as possible, and the pulling accuracy can be maintained to the greatest extent.
[0035] The fatigue detection device of this utility model also pays special attention to the structural design of the pull-out end 6, and has been optimized in particular to facilitate the insertion and snapping of the switch end 7. Specifically, in this embodiment, the pull-out end 6 has a mounting cavity 15 for the switch end to be inserted into. The mounting cavity 15 has symmetrically arranged limiting parts 16. After the switch end 7 is inserted into the mounting cavity 15, the head of the switch end 7 is supported and limited by the limiting parts 16. The mounting cavity 15 is also provided with a lateral insertion opening (unmarked) to facilitate the insertion of the switch end 7 from the insertion opening. The pull-out end 6 is constructed as a single unit with a mounting cavity 15. The mounting cavity 15 has a lateral insertion opening and a bottom opening (unmarked). The limiting parts 16 are located on both sides of the bottom opening. Thus, the switch end 7 is inserted from the insertion opening and enters the mounting cavity 15 along the bottom opening. At this time, the limiting parts 16 on both sides of the bottom opening support and limit the head of the switch end 7. It should be noted that the head of the switch terminal 7 extends radially outward by a certain distance, thus forming a radially outward flange, which is used to support and limit the position on the limiting part 16. This method uses lateral insertion and lateral release to achieve snap-fit, which is relatively convenient and time-saving in operation, and does not require the use of bolts or other tightening operations.
[0036] In this embodiment, the pressure platform 4 has a pressure plate component for fixing the magnetic box holder 5. The pressure plate component is pressed against the top of the magnetic box holder 5, and there are two pressure plate components, which are symmetrically arranged on both sides of the magnetic box holder 5.
[0037] Specifically, the pressure plate component includes a pressure plate 17. One end of the pressure plate 17 is screwed onto the pressure platform 4 via a connector 18, and the other end of the pressure plate 17 is pressed tightly against the top of the magnetic box holder 5. In this embodiment, the connector 18 is provided on one end of the pressure plate 17, and the connector 18 is screwed onto one end of the pressure platform 4. This achieves a tight connection between one end of the pressure plate 17 and the pressure platform 4. When it is necessary to remove the pressure plate 17 from the top of the magnetic box holder 5, the pressure plate 17 can be rotated slightly. At this time, the pressure plate 17 can rotate around the connector 18 by a certain angle and move away from the top of the magnetic box holder 5.
[0038] It should be noted that the magnetic box holder 5 has a magnetic box housing 20 and a switch end 7, with the switch end 7 extending from the center of the top of the magnetic box housing 20. When the switch end 7 of the magnetic box holder 5 is in the pressed-down state, the magnetic block of the magnetic box holder 5 is attracted and fixed on the pressure platform 4, while the two ends of the magnetic box housing 20 are pressed and fixed by two pressure plates 17. During the pulling process, the pulling end 6 pulls the switch end 7 upward, causing the magnetic block of the magnetic box holder 5 to detach from the pressure platform 4, thus completing one pulling operation. After this pulling operation is completed, during the return stroke of the driver 5, the pulling end 6 is driven to return downward, pressing the switch end 7 downward back to its original position, causing the magnetic block of the magnetic box holder 5 to be attracted on the pressure platform 4, thus completing the return operation. Then the pulling operation is repeated, and so on, automatically, until the magnetic box holder 5 shows partial damage, malfunction, or weakened adsorption strength. At this point, the maximum number of pulls that the magnetic box holder 5 can achieve can be detected, thus obtaining the final fatigue test.
[0039] It should be noted that the fatigue detection device of this utility model can be automated throughout the entire detection process, eliminating the need for personnel to manually pull and stretch the device. Specifically, personnel can observe the device after multiple pulls and stretches of the magnetic box holder 5, when a problem is anticipated. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
