Description

Technical Field

[0001] This utility model relates to the field of anchor testing technology, specifically a testing device for pull-out force testing. Background Technology

[0002] Anchors, also known as anchor bolts, are a general term for all post-anchoring components. They are broad in scope and can be divided into metal anchors and non-metal anchor bolts according to different raw materials. After the anchors are produced, the pull-out force of the anchors needs to be tested to ensure the quality of the anchors.

[0003] For example, patent application number CN202420077347.5 discloses an anchor pull-out force testing device, belonging to the field of anchor pull-out testing technology. It mainly includes a bracket with a downward-facing drive unit mounted on its top, the output rod of which is fitted with a tension detector; a pressing plate mounted on the bottom of the tension detector; and a pull-out assembly including a support plate with a guide post mounted on its top. The pressing plate is sleeved on the outer surface of the guide post, and a stop block is provided on the top of the guide post. A limit component is provided on the pull-out assembly. This anchor pull-out force testing device, through the limit component, can initially fix the anchor, drive the output rod of the drive unit to extend and cause the pressing plate to press the anchor into the material to be tested. After the output rod of the drive unit retracts, the anchor can be pulled out, and the pull force required for the anchor to be pulled out is measured simultaneously. This makes it easier to drive the anchor into the material, and the testing process is simpler and faster.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, although the aforementioned equipment can solve the problem of having to use tools such as hammers to drive anchors into the material, then move the testing device in the aforementioned technical solution to the anchor, drive two fixing plates to stably clamp and fix the outer wall of the anchor bolt, and finally pull it out with a cylinder, the operation is relatively cumbersome and affects the time required for testing.

[0005] However, during use, the force generated when the anchor is pulled out by the pull-out test device is usually large. The anchor will lose its fixing force after being pulled out, which makes it easy for the anchor to fly out. Moreover, the staff are right next to the pull-out test device, which can easily cause injury to the user. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a testing device for pull-out force testing, which has the advantage of preventing anchors from flying out. It solves the problem that the force generated when anchors are pulled out through the pull-out testing device is usually large, and the anchors will lose their fixing force after being pulled out, which makes it easy for the anchors to fly out when they are pulled out. Moreover, the staff are right next to the pull-out testing device, which can easily cause injury to the user.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a testing device for pull-out force testing, comprising a pull-out force tester, a pull-out component, and an anchor pin. The anchor pin is inserted into the front side of the pull-out component. The two sides of the top of the pull-out component are fixedly connected to the output end of the pull-out force tester. A protective cover is fixedly connected to the top of the pull-out component. A protective plate is slidably connected to the front side of the protective cover. Limiting components are fixedly connected to the bottom of both sides of the back of the protective plate. Positioning components are fixedly connected to the top of both sides of the front of the pull-out component.

[0008] As a preferred embodiment of the present invention, the limiting component includes a limiting slider, the front of which is fixedly connected to the bottom of both sides of the back of the protective plate, and limiting grooves are provided on both sides of the front of the protective cover, with the inner wall of the limiting grooves slidably connected to the surface of the limiting slider.

[0009] In a preferred embodiment of this invention, the positioning component includes an electromagnet, the back of which is fixedly connected to the top of both sides of the front of the puller, an iron plate is magnetically attracted to the top of the electromagnet, and the back of the iron plate is fixedly connected to the bottom of both sides of the front of the protective plate.

[0010] As a preferred embodiment of this utility model, a transmission plate is fixedly connected to the top of the protective plate, and a tension spring is fixedly connected to the top of the transmission plate. Three tension springs are arranged in a triangular pattern and are evenly distributed. The other end of the tension spring is fixedly connected to the bottom of the pull-out force tester.

[0011] As a preferred embodiment of this invention, limit strips are fixedly connected to the front sides of both sides of the top of the protective cover, and the limit strips are located at the top of the limit slider.

[0012] As a preferred embodiment of this invention, a protective pad is provided on the top of the electromagnet, and the protective pad is arranged in a mesh pattern.

[0013] As a preferred embodiment of this utility model, a first Velcro fastener is fixedly connected to the rear side of both sides of the protective pad, and a second Velcro fastener is attached to the back of the first Velcro fastener. The back of the second Velcro fastener is fixedly connected to the top of both sides of the front of the puller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting a protective cover, can cover the top of the anchor nail surface, and then cover the front of the protective cover with a protective plate. This ensures that if the anchor nail flies out during the pulling process, it is fully blocked by the protective cover and the protective plate, preventing the anchor nail from flying out and hitting the user and causing injury. It solves the problem that the force generated when the anchor nail is pulled out by the pull-out test device is usually large, and the anchor nail loses its fixing force after being pulled out, which makes it easy for the anchor nail to fly out when it is pulled out. Moreover, the staff are right next to the pull-out test device, which can easily cause injury to the user. This invention achieves the effect of preventing the anchor nail from flying out.

[0015] 2. By setting a limiting component, when the user needs to insert the pull-out piece with another anchor that needs to be tested and prepares to pull it out, the user can move the protective plate upward so that the front of the protective cover is exposed, so that the user can connect the pull-out piece with the anchor. During the movement of the protective plate, the limiting slider will move along the inner wall of the limiting groove, thereby limiting the movement of the protective plate in the left, right and forward and backward, and preventing the protective plate from separating from the protective cover.

[0016] 3. By setting a positioning component, after the anchor and the pull-out piece are connected and the protective plate covers the opening of the protective cover, the protective plate will drive the iron plate to move downward synchronously, so that the bottom of the iron plate is close to the top of the electromagnet. Then the electromagnet is activated, so that the electromagnet generates an attraction force to attract the iron plate, so that the protective plate can be fixed during the protection process, thereby ensuring the stability of the protective plate during use.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, the present invention provides a testing device for pull-out force testing, including a pull-out force tester 1, a pull-out component 2, and an anchor 3. The anchor 3 is inserted into the front of the pull-out component 2. The two sides of the top of the pull-out component 2 are fixedly connected to the output end of the pull-out force tester 1. A protective cover 4 is fixedly connected to the top of the pull-out component 2. A protective plate 5 is slidably connected to the front of the protective cover 4. Limiting components 6 are fixedly connected to the bottom of both sides of the back of the protective plate 5. Positioning components 7 are fixedly connected to the top of both sides of the front of the pull-out component 2.

[0021] refer to Figure 3 The limiting component 6 includes a limiting slider 61. The front of the limiting slider 61 is fixedly connected to the bottom of both sides of the back of the protective plate 5. Limiting grooves 62 are opened on both sides of the front of the protective cover 4. The inner wall of the limiting groove 62 is slidably connected to the surface of the limiting slider 61.

[0022] As a technical optimization of this utility model, by setting a limiting component 6, when the user needs to insert the puller 2 into the anchor 3 that needs to be tested and prepare to pull it out, the user can move the protective plate 5 upward so that the front of the protective cover 4 is exposed, so that the user can connect the puller 2 and the anchor 3. During the movement of the protective plate 5, the limiting slider 61 will move along the inner wall of the limiting groove 62, thereby limiting the movement of the protective plate 5 in the left, right and forward and backward, so as to prevent the protective plate 5 from separating from the protective cover 4.

[0023] refer to Figure 2 The positioning component 7 includes an electromagnet 71, the back of which is fixedly connected to the top of both sides of the front of the puller 2, and an iron plate 72 is magnetically attracted to the top of the electromagnet 71. The back of the iron plate 72 is fixedly connected to the bottom of both sides of the front of the protective plate 5.

[0024] As a technical optimization of this utility model, by setting the positioning component 7, after the anchor 3 and the puller 2 are connected and the protective plate 5 covers the opening of the protective cover 4, the protective plate 5 will drive the iron plate 72 to move downward synchronously, so that the bottom of the iron plate 72 is close to the top of the electromagnet 71. Then the electromagnet 71 is activated, so that the electromagnet 71 generates an attraction force to attract the iron plate 72, so that the protective plate 5 can be fixed during the protection process, thereby ensuring the stability of the protective plate 5 during use.

[0025] refer to Figure 1 A transmission plate 8 is fixedly connected to the top of the protective plate 5, and a tension spring 13 is fixedly connected to the top of the transmission plate 8. Three tension springs 13 are provided and are distributed in a triangular shape at equal intervals. The other end of the tension spring 13 is fixedly connected to the bottom of the pull-out force tester 1.

[0026] As a technical optimization of this utility model, by setting a transmission plate 8 and a tension spring 13, when the protective plate 5 moves downward to cover the front of the protective cover 4, the transmission plate 8 will move downward simultaneously, causing the transmission plate 8 to pull one end of the tension spring 13 downward. Then the tension spring 13 will generate tension. When the user needs to open the protective cover 4 to close the electromagnet 71, the tension of the tension spring 13 will be released, thereby automatically pulling the protective plate 5 upward to open.

[0027] refer to Figure 3 Limiting strips 9 are fixedly connected to the front sides of both sides of the top of the protective cover 4, and the limiting strips 9 are located on the top of the limiting slider 61.

[0028] As a technical optimization of this utility model, by setting a limiting strip 9, which is located at the top of the limiting slider 61, the maximum upward movement distance of the limiting slider 61 is limited by the limiting strip 9, thus preventing the protective plate 5 from disengaging from the limiting groove 62 when it drives the limiting slider 61 to move upward.

[0029] refer to Figure 2 The top of the electromagnet 71 is provided with a protective pad 10, which is arranged in a mesh pattern.

[0030] As a technical optimization of this utility model, by setting a protective pad, the impact force generated when the electromagnet 71 is turned on to attract the iron plate 72 can be buffered by the protective pad, so as to avoid the electromagnet 71 being damaged due to excessive impact force. Furthermore, by using the protective pad to be set in a mesh shape, the protective pad does not affect the magnetic attraction effect of the electromagnet 71 during the process of protecting the electromagnet 71.

[0031] refer to Figure 2The back sides of both sides of the protective pad 10 are fixedly connected with the first hook and loop fastener 11, and the back of the first hook and loop fastener 11 is attached with the second hook and loop fastener 12. The back of the second hook and loop fastener 12 is fixedly connected to the top of both sides of the front of the puller 2.

[0032] As a technical optimization of this utility model, by setting the first hook and loop fastener 11 and the second hook and loop fastener 12, when the protective pad 10 is damaged after long-term use and needs to be replaced, the user can pull the protective pad 10 to the front, so that the protective pad 10 causes the first hook and loop fastener 11 and the corresponding second hook and loop fastener 12 to separate. Then the user can stick the first hook and loop fastener 11 and the corresponding second hook and loop fastener 12 on the new protective pad 10, thus giving the user a point of force that is easy to apply.

[0033] The working principle and usage of this utility model are as follows: When the user starts the pull-out force tester 1 to drive the pull-out component 2 to pull out the anchor 3, the protective cover 4 covers the top of the anchor 3, and then the protective plate 5 covers the front of the protective cover 4. This ensures that if the anchor 3 flies out during the pulling process, it is adequately blocked by the protective cover 4 and the protective plate 5, preventing the anchor 3 from flying out and hitting the user and causing injury. When the user needs to insert the pull-out component 2 into another anchor 3 that needs to be tested and prepare to pull it out, the user can move the protective plate 5 upwards to expose the front of the protective cover 4, making it easier for the user to pull out the pull-out component 2. When the protective plate 5 is connected to the anchor 3, it will move the limiting slider 61 along the inner wall of the limiting groove 62 during the movement of the protective plate 5, thereby limiting the movement of the protective plate 5 in the left, right and forward and backward, so as to prevent the protective plate 5 from separating from the protective cover 4. After the anchor 3 is connected to the puller 2 and the protective plate 5 covers the opening of the protective cover 4, the protective plate 5 will move the iron plate 72 downward in sync, so that the bottom of the iron plate 72 is close to the top of the electromagnet 71. Then the electromagnet 71 is activated, so that the electromagnet 71 generates an attraction force to attract the iron plate 72, so that the protective plate 5 can be fixed during the protection process, thereby ensuring the stability of the protective plate 5 during use.

[0034] In summary, this pull-out force testing equipment, by setting up a protective cover 4, can cover the top of the anchor nail 3, and then cover the front of the protective cover 4 with a protective plate 5. This ensures that if the anchor nail 3 flies out during the pull-out process, it is adequately blocked by the protective cover 4 and the protective plate 5, preventing the anchor nail 3 from flying out and hitting the user and causing injury. This solves the problem that the force generated when the anchor nail is pulled out by the pull-out testing device is usually large, and the anchor nail loses its fixing force after being pulled out, making it easy for the anchor nail to fly out when pulled out, and the staff is right next to the pull-out testing device, which can easily cause injury to the user.
