Description

Technical Field

[0001] The utility model relates to the technical field of static load anchoring auxiliary equipment, in particular to a static load anchoring support device. Background Art

[0002] After production, prestressed concrete tendons require static anchoring tests using a static anchoring tester. Currently, known static anchoring testers consist of a loading jack, a dynamometer sensor, a displacement sensor, and computer software. Anchors, clamps, or connectors are placed at both ends of the static anchoring tester. After assembly through the prestressed tendons, initial stress is applied according to specifications. The assembly is then loaded until failure. The ultimate tensile stress and corresponding displacement change are measured, which contribute to the calculation of the efficiency coefficient and total elongation.

[0003] The patent with announcement number CN207163813U discloses "a sample support device for static load anchoring test, including a vertically arranged front support frame, and the four end corners of the front support frame are connected with fixed connecting rods, the two fixed connecting rods located at the bottom are connected to the first side rib, and the other ends of the two fixed connecting rods located at the bottom are connected to the first connecting mechanism; the two fixed connecting rods located at the top are connected to the second side rib, and the other ends of the two fixed connecting rods located at the top are connected to the second connecting mechanism. This structure solves the problem that the existing support device cannot be applied to most samples."

[0004] Regarding the above-mentioned related technologies, the inventors believe that in actual use, the static load anchoring test may test multiple prestressed tendon samples at the same time, while it can only support a single prestressed tendon sample to assist in the test, with a relatively limited scope of use and low test efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention provides a static load anchoring support device, and the specific technical solution is as follows:

[0006] A static load anchoring support device, comprising a static load anchoring test body and a support mechanism mounted on the middle inner portion of the static load anchoring test body, the support mechanism comprising a plurality of support members sequentially arranged from top to bottom on the middle inner portion of the static load anchoring test body for supporting a test sample, and a height adjustment mechanism mounted on the middle inner portion of the static load anchoring test body for adjusting the height of the support members;

[0007] The height adjustment mechanism includes a base plate fixedly arranged in the middle of the inner side of the static load anchoring test body, and several groups of threaded rods rotatably arranged on the top of the base plate. The support member includes a connecting seat threaded on the outer wall of the threaded rod, a round rod fixed between two adjacent connecting seats, and a rotating drum rotatably arranged on the outer wall of the round rod for lifting the test sample.

[0008] By adopting the above technical solution, multiple prestressed tendon samples can be supported simultaneously by several support members of different heights to assist in testing, which can greatly improve the test efficiency. Moreover, since the support member is arranged in the middle of the static load anchor test body, when the sample is inserted from one end of the static load anchor test body to the other end, the middle support member can support the sample, so that one end of the sample is not easy to droop naturally during the insertion process and is difficult to enter the installation position at the other end of the static load anchor test body.

[0009] Optionally, a plurality of protective covers are rotatably provided on one side of the static load anchoring test body, and a handle is fixedly provided on the outside of the protective cover.

[0010] By adopting the above technical solution, the staff can hold the handle to open the protective cover.

[0011] Optionally, a plurality of rotation grooves are provided on the top of the base plate, a rotation plate is rotatably connected in the rotation grooves of the base plate, and the threaded rod is fixedly connected to the top center of the rotation plate.

[0012] By adopting the above technical solution, the rotating plate can connect the bottom plate and the threaded rod, so that the threaded rod can rotate on the top of the rotating plate without being separated.

[0013] Optionally, a lubricating oil groove for adding lubricating oil to the connection between the threaded rod and the connecting seat is opened on the top of the connecting seat, and a sealing ring for sealing between the threaded rod and the connecting seat is fixedly provided on the bottom of the connecting seat.

[0014] By adopting the above technical solution, the lubricating oil in the lubricating oil tank can continuously lubricate the connection between the threaded rod and the connecting seat, preventing the connection between the threaded rod and the connecting seat from rusting and becoming difficult to rotate.

[0015] Optionally, a transmission mechanism is provided between two adjacent threaded rods, and the transmission mechanism includes a flywheel fixed to the outer wall of the bottom end of the threaded rod, and a chain meshingly connected between the outer walls of the two adjacent flywheels, and a plurality of grips for holding are fixed on the outer wall of the chain, and an anti-slip sleeve is fixed on the outer wall of the grip.

[0016] By adopting the above technical solution, the chain is pulled by the grip rod, and in conjunction with the connection of the flywheel, the two adjacent threaded rods can be driven to rotate, thereby driving the support member to rise and fall, making it easy to adjust the support member's lifting and support height for the test sample.

[0017] In summary, the present invention has at least one of the following beneficial effects:

[0018] 1. Several supports of different heights can simultaneously support multiple prestressed tendon samples to assist in the static load anchoring test, which can greatly improve the test efficiency. Moreover, since the support is arranged in the middle of the static load anchoring test body, when the sample is inserted from one end of the static load anchoring test body to the other end, the middle support can support the sample, so that one end of the sample is not easy to sag naturally during the insertion process and enter the installation position at the other end of the static load anchoring test body. In addition, the rotation of the outer rotating drum of the support can reduce the resistance of the staff when pushing the sample, which is convenient and practical.

[0019] 2. By pulling the chain through the grip and coordinating with the connection of the flywheel, the two adjacent threaded rods can be driven to rotate, thereby driving the support to rise and fall, which is convenient for adjusting the support and support height of the test sample. It has a wide range of applications. The lubricating oil in the lubricating oil tank can continuously lubricate the connection between the threaded rod and the connecting seat, avoiding rust and difficulty in rotation at the connection between the threaded rod and the connecting seat. As the support rises and falls, the lubricating oil in the connecting seat can lubricate other positions of the threaded rod, thereby extending the service life of the threaded rod.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-5 The utility model is described in further detail.

[0027] The utility model discloses a static load anchoring support device, referring to Figure 1-3, including a static load anchoring test body 1, a support member 2 and a height adjustment mechanism, the support member 2 and the height adjustment mechanism constitute a support mechanism for supporting prestressed tendon samples.

[0028] Reference Figure 1-2 A plurality of protective covers 11 are rotatably provided on one side of the static load anchoring test body 1, and a handle 12 is fixedly provided on the outside of the protective cover 11. The protective cover 11 can cover the static load anchoring test body 1 during testing and experimenting to prevent the prestressed tendon sample from splashing out after breaking and injuring surrounding objects and people. The staff can hold the handle 12 to open the protective cover 11. The static load anchoring test body 1, the protective cover 11 and the handle 12 constitute the existing static load anchoring test machine, which can perform static load anchoring tests on prestressed tendon samples. Its internal structure and principle have been disclosed and will not be elaborated on here.

[0029] Reference Figure 2-4 The height adjustment mechanism includes a base plate 3 fixedly arranged at the middle part of the inner side of the static load anchoring test body 1, and several groups of threaded rods 31 rotatably arranged at the top of the base plate 3. Several groups of rotating grooves 32 are opened on the top of the base plate 3. A rotating plate 33 is rotatably connected in the rotating groove 32 of the base plate 3. The threaded rod 31 is fixedly connected at the top center of the rotating plate 33. The rotating plate 33 is a circular plate shape. The base plate 3 can connect and limit the rotating plate 33 through the rotating groove 32. The rotating plate 33 can connect the base plate 3 and the threaded rod 31, so that the threaded rod 31 can rotate on the top of the rotating plate 33 without disengaging.

[0030] Reference Figure 3-5 A transmission mechanism is provided between two adjacent threaded rods 31, and the transmission mechanism includes a flywheel 4 fixed on the outer wall of the bottom end of the threaded rod 31, and a chain 41 meshedly connected between the outer walls of the two adjacent flywheels 4. The chain 41 can connect the two adjacent threaded rods 31 through the flywheel 4.

[0031] Reference Figure 3-5 The outer wall of the chain 41 is fixed with a plurality of grips 42 for holding, and the outer wall of the grip 42 is fixed with an anti-slip sleeve 43. The anti-slip sleeve 43 can reduce the chance of the staff's hand slipping when holding the chain 41. The staff can hold the grip 42 to pull the chain 41. After the chain 41 moves, it can drive the two adjacent meshing flywheels 4 to rotate synchronously in the same direction, thereby driving the two adjacent threaded rods 31 to rotate synchronously in the same direction.

[0032] Reference Figure 3-4The support member 2 includes a connecting seat 21 threaded on the outer wall of the threaded rod 31, a round rod 22 fixed between two adjacent connecting seats 21, and a rotating drum 23 rotatably arranged on the outer wall of the round rod 22 for lifting the test sample. The threaded rod 31 can support and limit the connecting seat 21, the round rod 22 can connect two adjacent connecting seats 21, and can carry and support the rotating drum 23. The rotating drum 23 can rotate on the round rod 22. Several support members 2 with different heights can simultaneously support multiple prestressed tendon samples on the top through the rotating drum 23 to assist in testing, which can greatly improve the test efficiency. After the two adjacent threaded rods 31 rotate, they can drive the two connecting seats 21, the round rod 22 and the rotating drum 23 to move up and down, thereby driving the support member 2 to move up and down, which is convenient for adjusting the lifting and support height of the test sample by the support member 2, and has a wide range of applications.

[0033] And because the support member 2 is arranged in the middle of the static load anchoring test body 1, when the sample is inserted from one end of the static load anchoring test body 1 to the other end, the middle support member 2 can support the sample, so that one end of the test sample is not easy to droop naturally during the insertion process and is difficult to enter the installation position at the other end of the static load anchoring test body 1.

[0034] Reference Figure 4 A lubricating oil groove 24 is provided on the top of the connecting seat 21 for adding lubricating oil to the connection between the threaded rod 31 and the connecting seat 21. The staff can add lubricating oil into the lubricating oil groove 24. The lubricating oil in the lubricating oil groove 24 can continuously lubricate the connection between the threaded rod 31 and the connecting seat 21, preventing the connection between the threaded rod 31 and the connecting seat 21 from rusting and becoming difficult to rotate. Moreover, as the support member 2 rises and falls, the lubricating oil in the connecting seat 21 can lubricate other positions of the threaded rod 31, thereby extending the service life of components such as the threaded rod 31.

[0035] Reference Figure 4 A sealing ring 25 is fixedly provided at the bottom of the connecting seat 21 for sealing between the threaded rod 31 and the connecting seat 21. A fixing hole is opened at the bottom of the connecting seat 21. The sealing ring 25 is fixed in the fixing hole of the connecting seat 21. The fixing hole can hide the sealing ring 25. The sealing ring 25 can seal between the threaded rod 31 and the bottom of the connecting seat 21, so that the lubricating oil is not easy to leak from the bottom of the connecting seat 21, thereby extending the service life of the lubricating oil.

[0036] The implementation principle of a static load anchor support device according to an embodiment of the present invention is as follows:

[0037] During use, the staff can hold the handle 12 to open the protective cover 11 from the static load anchoring test body 1, and then insert multiple prestressed tendon samples from one end of the static load anchoring test body 1 into the other end. During the insertion process, several support members 2 of different heights can simultaneously support multiple prestressed tendon samples from the middle of the static load anchoring test body 1 to assist the static load anchoring test, which can greatly improve the test efficiency.

[0038] At the same time, during the insertion process, the drum 23 can reduce the resistance of the staff when inserting and pushing the sample by rotating itself;

[0039] When the height of the support member 2 needs to be adjusted, the staff can hold the handle 42 to pull the chain 41. After the chain 41 moves, it can drive the two adjacent meshing flywheels 4 to rotate synchronously in the same direction, thereby driving the two adjacent threaded rods 31 to rotate synchronously in the same direction. After the two adjacent threaded rods 31 rotate, they can drive the two connecting seats 21, the round rod 22 and the rotating drum 23 to move up and down, thereby driving the support member 2 to move up and down, which is convenient for adjusting the support member 2 to lift and support the test sample, and has a wide range of applications.

[0040] The staff can add lubricating oil into the lubricating oil tank 24. The lubricating oil in the lubricating oil tank 24 can continuously lubricate the connection between the threaded rod 31 and the connecting seat 21 to prevent the connection between the threaded rod 31 and the connecting seat 21 from rusting and becoming difficult to rotate. Moreover, as the support member 2 rises and falls, the lubricating oil in the connecting seat 21 can lubricate other positions of the threaded rod 31, thereby extending the service life of components such as the threaded rod 31. The sealing ring 25 can seal between the threaded rod 31 and the bottom of the connecting seat 21, so that the lubricating oil is not easy to leak from the bottom of the connecting seat 21, thereby extending the service life of the lubricating oil.
