[0021] 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.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, this utility model provides a field simulation device for pull-out resistance test of support anchor rods, including a base plate 1, a sliding sleeve 2 fixedly installed on the top of the base plate 1, a through shaft 3 inserted into the inside of the sliding sleeve 2, an assembly plate 4 fixedly installed on the top of the through shaft 3, a screw 5 fixedly installed on the bottom of the assembly plate 4, the screw 5 being slidably connected to the base plate 1, a jack base 6 fixedly installed on the top of the assembly plate 4, a through jack 7 fixedly installed on the top of the jack base 6, a tool anchor 11 fixedly installed on the top of the through jack 7, and a support anchor rod 10 inserted into the inside of the tool anchor 11.

[0024] The support anchor 10 passes through the tool anchor 11, the through jack 7, the assembly plate 4, the through shaft 3, and the base plate 1 respectively. The upper part is fixed by the tool anchor 11. When the hydraulic hose 13 is activated to push the internal output shaft of the through jack 7 upward, a large tensile force will be generated in the middle of the support anchor 10. At this time, the tensile force will test the pull-out resistance of the support anchor 10, and the support anchor 10 used in the construction site will be tested to see if it has a qualified effect.

[0025] Among them, a limiting sleeve 8 is fixedly installed at the bottom of the base plate 1, and an anchor plate 9 is inserted into the inside of the limiting sleeve 8. The support anchor rod 10 is located inside the limiting sleeve 8.

[0026] The top of the anchor plate 9 is located inside the limiting sleeve 8, and the inner side of the anchor plate 9 is in contact with the through-hole jack 7. When it is necessary to conduct a simulated test on the support anchor rod 10, the bottom of the support anchor rod 10 is fixed, which makes it convenient for the whole device to pull the middle part of the support anchor rod 10.

[0027] Among them, a limiting piece 14 is fixedly installed on the outer side of the screw 5, and a nut 15 is engaged on the outer side of the screw 5. The limiting piece 14 is located at the bottom of the base plate 1.

[0028] The main function of the limiting piece 14 is to limit the bottom of the base plate 1 to maintain a certain degree of stability.

[0029] The hydraulic hose 13 is fixedly installed on the outside of the through-hole jack 7, and a hydraulic system is fixedly installed on the end of the hydraulic hose 13 away from the jack base 6.

[0030] The hydraulic system controls the internal pressure of the through-hole jack 7 through the hydraulic hose 13, thereby causing the output end of the through-hole jack 7 to extend and retract, thus providing a pulling force.

[0031] The top of the support anchor 10 is fixedly equipped with a displacement measuring instrument 12, which is located above the tool anchor 11.

[0032] The main function of the displacement measuring instrument 12 is to detect the distance that the support anchor rod 10 is pulled out, so as to provide accurate data.

[0033] There are three screws 5, and the bottom diameter of the three screws 5 is smaller than the diameter of the three screws 5 above the limiting plate 14.

[0034] In addition to supporting the device, the three screws 5 also fix the entire device in the testing position during simulated testing, thus maintaining overall stability.

[0035] Among them, the diameter of the sliding sleeve 2 is greater than the diameter of the through shaft 3, the diameter of the sliding sleeve 2 is less than the diameter of the assembly plate 4, and the inside of the sliding sleeve 2 is hollow.

[0036] The main function of the sliding sleeve 2 is to connect the through shaft 3. The height of the through shaft 3 is higher than that of the sliding sleeve 2. The main function is to make the sliding sleeve 2 slide with the reserved height, so as to clearly simulate the elongation of the free section of the support anchor rod and make it have the effect of simulation detection.

[0037] Example 2

[0038] like Figures 4 to 5 As shown, the difference from Embodiment 1 is that a spring 16 is fixedly installed on the top of the base plate 1. The spring 16 is located at the bottom of the through shaft 3 and is fixedly connected to the through shaft 3. The spring 16 is located on the outside of the support anchor rod 10.

[0039] The main function of spring 16 is to activate the hydraulic system when the device is performing simulated testing on the support anchor rod 10. This allows the output shaft of the through-hole jack 7 to slide up and down through the hydraulic hose 13, thereby causing the tool anchor 11 to drive the support anchor rod 10 to generate an upward pulling force. At this time, the sliding sleeve 2 will pull upward, causing the base plate 1 to slide on the outside of the screw rod 5. Simultaneously, spring 16 will contract, causing the sliding sleeve 2 to slide on the outside of the through-hole shaft 3, so that it can also clearly simulate the elongation of the free section of the support anchor rod, achieving the effect of simulated testing.

[0040] Working principle and usage process of this utility model:

[0041] First, the support anchor rod 10 is passed through the anchor plate 9, the limiting sleeve 8, the base plate 1, the sliding sleeve 2, the through shaft 3, the assembly plate 4, the jack base 6, the through jack 7, and the tool anchor 11 in sequence so that the bottom end of the screw rod 5 contacts the ground. At the same time, the bottom of the nut 15 is fixed to ensure the overall stability during the simulation test. Meanwhile, the anchor plate 9 is inserted into the limiting sleeve 8 so that the anchor plate 9 completely wraps around the support anchor rod 10, so that the support anchor rod 10 is limited and locked.

[0042] Meanwhile, a jack base 6 is fixedly installed above the assembly plate 4, and a hydraulic hose 13 is fixedly installed on the outside of the through jack 7. A hydraulic system is connected to the end of the hydraulic hose 13 away from the jack base 6. A through jack 7 is fixedly installed above the jack base 6, and a tool anchor 11 is fixedly installed above the through jack 7. When the support anchor 10 is inserted into the tool anchor 11 and the through jack 7, the tool anchor 11 clamps and fixes the support anchor 10. The hydraulic system is started, and the output end of the through jack 7 is pushed upward through the hydraulic hose 13 to generate a pulling force, thereby testing the pull-out resistance of the support anchor 10 and achieving the effect of facilitating simulation testing.

[0043] Three screws 5 are fixedly installed at the bottom of the jack base 6. The three screws 5 are slidably connected to the base plate 1, and the diameter of the bottom of the three screws 5 is smaller than the diameter of the three screws 5 above the limiting plate 14. Before the simulation test, the three screws 5 drive the whole device to be fixed in the designated position for the test, so that the device maintains a certain stability during the simulation test.

[0044] Finally, since the bottom of the base plate 1 is fixedly installed with a limiting sleeve 8, and an anchor plate 9 is inserted inside the limiting sleeve 8, when the support anchor rod 10 is inserted into the limiting sleeve 8 through the base plate 1, the anchor plate 9 fits with the support anchor rod 10 and is limited by the limiting sleeve 8, so that the position of the support anchor rod 10 is limited and the bottom of the support anchor rod 10 is fixed.
