Description

Technical Field

[0001] The utility model belongs to the technical field of building detection, and in particular relates to an anchor anti-pullout force testing device. Background Art

[0002] After the anchor is fixed, it needs to be pulled out to detect the construction quality of the anchor in real time.

[0003] A Chinese patent document with authorization publication number CN221405023U discloses an anchor pull-out force test device. After the test device is placed on the anchor to be tested, the anchor is clamped by a wedge-shaped steel plate whose movable range is limited by the trapezoidal hole in the rectangular block. This ensures the service life of the wedge-shaped steel plate while allowing the test device to be more securely connected to the anchor.

[0004] However, in the prior art, when the anchor is extremely resistant to pull-out, the parts in the experimental device that clamp the anchor are at risk of getting stuck as the force applied to the anchor increases during the process of pulling out the anchor. Therefore, an anchor pull-out resistance experimental device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an anchor anti-pullout force testing device.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] An anchor pullout test device includes a support assembly capable of limiting the pulling direction of the anchor by the device, a pulling assembly capable of pulling the anchor and transmitting the magnitude of the force applied during the pulling in real time, and a clamping assembly capable of stably clamping the anchor and allowing the device and the anchor to be easily separated after the test is completed.

[0008] The clamping assembly includes a clamping plate that can fully contact the part of the anchor to be tested that is exposed outside the building, a limiter that allows the clamping plate to initially clamp the anchor before the testing work begins, and a scissor member that can transmit the power from the pulling assembly to the clamping plate after the testing begins and enable the clamping plate to further clamp the anchor.

[0009] Preferably, the scissor fork member includes supports respectively fixedly connected to the front and rear of the pulling assembly, a connecting rod is movably connected below the support, a support arm is movably connected to the lower end of the connecting rod, and a plug rod is movably connected to the lower end of the support arm.

[0010] Preferably, a clamping plate is fixedly connected between two insertion rods at the same transverse position.

[0011] Preferably, the limiting member includes a limiting rod movably connected between the clamping plates, both ends of the limiting rod are fixedly connected with anti-slip rings, and the outer side surface of the limiting rod is movably connected with a spring.

[0012] Preferably, the support seat and the support arm are both rotatably connected to the connecting rod, the support arm is rotatably connected to the insertion rod, and the insertion rod is connected to the splint via threads.

[0013] Preferably, two adjacent supporting arms are rotatably connected.

[0014] Preferably, the clamping plate and the spring are both slidably connected to the limiting rod.

[0015] The beneficial effects of the present invention are: the two clamps that are conveniently separated and limited by the limit parts and the scissor parts through the movable range can clamp the anchor from both sides, so that the device can be quickly connected to the anchor before testing, and can clamp the anchor more stably during testing. After the test is completed, the device can be easily separated from the anchor, thereby ensuring the smooth progress of the testing work and effectively avoiding the jamming of the components that clamp the anchor.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.

[0026] like Figure 1-Figure 4 As shown, an anchor pull-out force test device includes a support component 1 that can limit the pulling direction of the anchor by the device, a pulling component 2 is provided on the support component 1, which can pull the anchor and transmit the force applied when it is pulled out in real time, and a clamping component 3 is provided on the pulling component 2, which can stably clamp the anchor and make the device and the anchor conveniently separable after the test is completed.

[0027] In this embodiment: the support assembly 1 includes a base 101, on which a vertical rod 102 is fixedly mounted, and an anti-drop block 103 is fixedly connected between the upper ends of the vertical rod 102;

[0028] The base 101 provides an installation position for the vertical rod 102 and some parts of the pulling assembly 2 without interfering with the lifting and lowering of the clamping assembly 3. The vertical rod 102 improves the stability of the pulling assembly 2 when driving the clamping assembly 3 to lift and lower, and avoids shaking of the clamping assembly 3 when lifting and lowering. The anti-slip block 103 prevents the pulling assembly 2 from being accidentally separated from the vertical rod 102.

[0029] In this embodiment: the pulling assembly 2 includes a hydraulic rod 201 fixedly installed in the base 101, the telescopic end of the hydraulic rod 201 is fixedly connected to a pressure sensor 202, and a bracket 203 is fixedly connected above the pressure sensor 202;

[0030] The vertical pole 102 is slidably connected to the bracket 203; the length change of the telescopic end of the hydraulic rod 201 is transmitted to the bracket 203 whose movable range is limited by the vertical pole 102 through the pressure sensor 202, so that the bracket 203 can drive the clamping assembly 3 to move up and down. At the same time, the pressure sensor 202 can detect the magnitude of the force applied to the bracket 203 by the hydraulic rod 201 in real time, and transmit it to its own external signal processing equipment in the form of a signal.

[0031] The cam 306 is fixedly connected to the cam 308 at the rear of the cam 309, and the cam 309 is fixedly connected to the rear of the cam 309.

[0032] The support 301 and the support arm 303 are both rotatably connected to the connecting rod 302, the support arm 303 is rotatably connected to the insertion rod 304, the insertion rod 304 is connected to the clamping plate 305 through a threaded connection, the two adjacent support arms 303 are rotatably connected, and the clamping plate 305 and the spring 308 are both slidably connected to the limit rod 306;

[0033] The connecting rod 302 is installed under the bracket 203 through the support 301, and the splint 305 is suspended through the connecting rod 302, the support arm 303, and the insertion rod 304, and the height change of the bracket 203 is transmitted to the splint 305, and the two splints 305 are prevented from being misaligned by the limiting rod 306, and the anti-slip ring 307 is used to prevent the spring 308 from falling off the limiting rod 306. The spring 308 makes the two splints 305 that are not subjected to external force tend to move toward each other.

[0034] Working Principle: When the device is installed and used for anchor pull-out test, it is necessary to move the device to the location of the anchor and align the anchor with the gap between the two clamps 305. The staff then pulls the two clamps 305 apart and puts the clamps 305 on the exposed part of the anchor outside the building. When the staff releases the clamps 305, the two clamps 305 will move toward each other under the action of the spring 308 to clamp the anchor, thus completing the initial connection between the device and the anchor.

[0035] After that, the hydraulic rod 201 can be operated to adjust the height of the bracket 203 so as to pull out the anchor away from the building. During the process of pulling out the anchor, the thrust from the hydraulic rod 201 applied to the bracket 203 will be transmitted to the clamping plate 305 through the support 301, the connecting rod 302, the support arm 303, and the insertion rod 304. Since the connecting rod 302 and the support arm 303 can change the direction in which the thrust is applied to the clamping plate 305, the clamping plate 305 will have a tendency to move upward and toward another clamping plate 305 under the action of the thrust. In this case, as the thrust from the hydraulic rod 201 gradually increases, the clamping plate 305 will pull out the anchor with greater force and increase the degree of clamping on the anchor, so that the anchor can be pulled out of the building while being stably clamped.

[0036] During the process of pulling out the anchor, the thrust applied by the hydraulic rod 201 to the bracket 203 can be detected and transmitted in real time by the pressure sensor 202. After the detection is completed, the connection between the device and the anchor can be quickly disconnected by pulling the splint 305 apart.

[0037] The preferred embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of technicians in the relevant technical field without departing from the purpose of the present invention.
