Description

Technical Field

[0001] The invention relates to the technical field of high slope support testing, and more specifically to a testing device and a construction method for mechanized high slope support. Background Art

[0002] High slope terrains need proper support to prevent landslides or collapses. High slope support is a special engineering technology that aims to protect the stability of high slope terrain. This technology usually involves a series of complex engineering operations, including soil stabilization, drainage system design, vegetation restoration, etc. Mechanized support is a support, reinforcement and protection measure for the side walls and surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit;

[0003] Slope support can effectively prevent soil from being eroded by natural forces such as wind, rain, and water flow. By installing mechanical support structures, the exposed area of ​​soil can be reduced and the speed of water flow can be reduced, thereby protecting the soil from being damaged. The support structure can provide additional support to help the slope resist the effects of external loads such as gravity and earthquakes, which helps to reduce the possibility of slope deformation and sliding and ensure its long-term stability. Through reasonable support design, the risk of accidents such as slope collapse can be reduced, and the safety of life and property of construction workers and surrounding residents can be guaranteed;

[0004] When the slope support device is used, its support performance needs to be tested. Only the support structure that passes the test can be used to ensure its support effect. When the current support device is tested, the test device needs to apply pressure to the support device, and judge its support performance according to the size of the applied force. However, the actual support environment is more complicated, and the force applied to the support device is not uniform. The current test device cannot apply different forces to the support device, so the test effect is limited.

[0005] When pressure is applied to the support device during testing, the support device is prone to move under the action of the force, so the support device needs to be fixed. Current test devices cannot quickly fix the support device, and it is more troublesome to remove and place the support device during testing. Summary of the invention

[0015] Technical effects and advantages of the present invention:

[0016] 1.

The through holes of the shielding plate and the pressure block are staggered with each other.

[0017] 2. The present invention is provided with an output screw, a moving block, and a pressure mechanism. When the servo motor is started, the output screw is driven to rotate. When the output screw rotates, the moving block is driven to move. When the moving block moves, the moving platform is driven to move. When the moving platform moves, the pressure mechanism above is driven to move synchronously. The pressure mechanism can move close to or away from the test bench. When the pressure mechanism is away from the test bench, it is convenient to put it into the mechanical support frame. When the pressure mechanism is close to the mechanical support frame, the mechanical support frame can be clamped to facilitate the test.

[0018] 3. In the present invention, when the output screw rotates, the driven bevel gear is driven to rotate through the output bevel gear. When the moving platform is close to the test platform, the synchronous screw rotates to make the lifting block move upward. When the lifting block moves upward, the connecting rod is driven upward through the lifting plate. The connecting rod moves upward in the sliding groove and drives the rotating plate to rotate around the connecting axis. At this time, the rotating plate moves downward away from the lifting plate, automatically pressing the mechanical support frame downward to prevent the mechanical support frame from moving during the test.

[0031] In the embodiment of the present application, the adjusting mechanism 8 is connected to the mobile platform 3 and the control end 6 respectively. When the adjusting mechanism 8 is in operation, the mobile platform 3 will be moved away from the test bench 2 as a whole. When the mechanical support frame 7 is placed above the test bench 2, it can be automatically fixed by moving the pressure-applying mechanism 4. In addition, it should be noted that when the hydraulic rod 402 in the pressure-applying mechanism 4 of the present application is working, the hydraulic pipeline connected to it is distributed on the side of the pressure-applying mechanism 4 away from the fixing mechanism 5.

[0032] Reference Figure 3 , Figure 4 , Figure 5 as well as Figure 6 The pressure mechanism 4 includes a support frame 401 fixedly connected to the moving platform 3, a hydraulic rod 402 is fixedly connected inside the support frame 401, a side of the hydraulic rod 402 away from the support frame 401 is fixedly connected to an ejector rod 403, and a pressure block 409 is movably connected to the side of the ejector rod 403, and the four corners of the top of the moving platform 3 are fixedly connected to a fixed plate 404, the top of the fixed plate 404 is fixedly connected to a connecting plate 405, the inside of the fixed plate 404 is fixedly connected to a fixed rod 407, and the side of the pressure block 409 is fixedly connected to a connecting block 406, and the inside of the pressure block 409 is provided with an avoidance hole adapted to the fixed rod 407, and the side of the fixed rod 407 is sleeved with a support spring 408. The bottom end of block 409 is fixedly connected to a placement frame 410, the bottom end of the placement frame 410 is fixedly connected to an electromagnet 411, the top of the electromagnet 411 is provided with a magnetic plate 412, the top of the magnetic plate 412 is fixedly connected to a baffle plate 413, the inside of the pressure block 409 is provided with a avoidance groove for the baffle plate 413 to move, the inside of the pressure block 409 and the baffle plate 413 are both provided with through holes adapted to the baffle plate 413, the number of ejector rods 403 and pressure blocks 409 are both four, and the four pressure blocks 409 are arranged in two rows and two columns, the four pressure blocks 409 are symmetrical about their center, and the support spring 408 is located on the side of the connecting block 406 away from the driven bevel gear 502.

[0033] In the embodiment of the present application, when the through hole of the shielding plate 413 and the through hole of the pressure block 409 overlap with each other, the ejection rod 403 can directly pass through the pressure block 409 and the shielding plate 413 when being ejected. The side of the pressure block 409 is connected to the connecting block 406, and the supporting spring 408 will apply elastic force to the connecting block 406, thereby preventing the ejection rod 403 from driving the pressure block 409 to move when passing through the pressure block 409. At this time, the ejection rod 403 will directly hit the side of the mechanical support frame 7 and apply force to the mechanical support frame 7 in a point manner. When the shielding plate 413 moves upward and the through hole of the pressure block 409 and the through hole of the shielding plate 413 are staggered with each other, the ejection rod 403 will be ejected again and will directly hit the side of the shielding plate 413, which will drive the shielding plate 413 to move. The plate 413 and the pressure block 409 move synchronously, and the pressure block 409 is pressed against the side of the mechanical support frame 7 as a whole, so that pressure is applied to the mechanical support frame 7 in a surface manner. Therefore, the present application can apply force in different ways of point or surface, and there are more ways to conduct tests, which can better test the support performance of the mechanical support frame 7. There are four structures such as the ejector rod 403, the pressure block 409 and the hydraulic rod 402. Therefore, the four ejector rods 403 and the pressure block 409 can perform point or surface ejection work respectively, which is more adapted to the complex environment during support. When the pressure block 409 moves, it will synchronously drive the connection block 406 to move. When the connection block 406 moves, it will compress the support spring 408, so it is convenient for the pressure block 409 to reset.

[0034] Reference Figure 3 and Figure 7 The adjustment mechanism 8 includes a servo motor 801 for providing power, an output screw 802 is fixedly connected to the side of the servo motor 801, a moving block 803 is threadedly connected to the side of the output screw 802 away from the servo motor 801, the top of the moving block 803 is fixedly connected to the bottom of the moving platform 3, the side of the output screw 802 close to the servo motor 801 is fixedly connected to the output bevel gear 806, both sides of the bottom of the moving platform 3 are fixedly connected with synchronization blocks 805, the internal movability of the synchronization block 805 is connected to the support rod 804, the side of the support rod 804 is fixedly connected to the side of the support leg 1, the bottom end of the control end 6 is fixedly connected to the mounting plate 807, and the side of the mounting plate 807 is fixedly connected to the side of the servo motor 801.

[0035] In the embodiment of the present application, when the moving block 803 moves away from the test bench 2, the moving block 803 synchronously drives the moving table 3 and the pressure mechanism 4 above the moving table 3 to move away from the test bench 2. At this time, the mechanical support frame 7 can be placed in. After the servo motor 801 controls the output screw 802 to reverse, the output screw 802 reverses, so that the moving table 3 drives the pressure mechanism 4 to move toward the test bench 2, and when the pressure mechanism 4 moves, it will push the mechanical support frame 7 toward the pressure mechanism 4, and the pressure mechanism 4 and the fixing mechanism 5 will automatically fix the mechanical support frame 7.

[0036] Reference Figure 7 , Figure 8 as well as Fig. 9 The fixing mechanism 5 includes a limit plate 501 for supporting, a synchronous screw 503 is movably connected to the bottom end of the limit plate 501, and a driven bevel gear 502 is fixedly connected to the bottom end of the synchronous screw 503, and the driven bevel gear 502 is meshed with the output bevel gear 806 in the adjusting mechanism 8, and a lifting block 504 is threadedly connected to the top of the synchronous screw 503, and a lifting plate 505 is fixedly connected to the top of the lifting block 504, and an avoidance groove for movement of the lifting block 504 and the lifting plate 505 is provided inside the limit plate 501, and a connecting rod 506 is fixedly connected to the top of the lifting plate 505, and sliding grooves 507 are movably connected to both sides of the connecting rod 506, and a rotating plate 508 is fixedly connected to the top of the sliding groove 507, and a rotating plate 508 is movably connected to the rotating plate 508. A connecting shaft 509 is movably connected inside the rotating plate 508, and a avoidance groove for rotation of the rotating plate 508 is provided at the top of the limit plate 501, and both sides of the connecting shaft 509 are fixedly connected to the avoidance groove at the top of the limit plate 501.

[0037] In the embodiment of the present application, when the output screw 802 rotates, the driven bevel gear 502 is synchronously rotated through the output bevel gear 806, and the driven bevel gear 502 drives the synchronous screw 503 to rotate. When the synchronous screw 503 rotates, the lifting block 504 can move up and down. When the lifting block 504 moves downward, the connecting rod 506 is driven downward by the lifting plate 505. The connecting rod 506 is in the sliding groove 507 and drives the sliding groove 507 to move, so that the sliding groove 507 drives the rotating plate 508 to rotate around the connecting shaft 509, and the connecting shaft 509 moves upward away from the side of the connecting rod 506. At this time, the mechanical support frame 7 can be placed in it, and the lifting plate 505 moves upward. When the connecting rod 506 drives the connecting rod 506 to move upward in the sliding groove 507, the rotating plate 508 moves downward away from the side of the lifting plate 505 and presses the mechanical support frame 7 to prevent the mechanical support frame 7 from moving during the test.

[0038] The working principle of the present invention is as follows: before the test, the servo motor 801 is started and drives the output screw 802 to rotate. When the output screw 802 rotates, the moving block 803 moves away from the test bench 2. The moving block 803 synchronously drives the moving platform 3 and the pressure mechanism 4 above the moving platform 3 to move away from the test bench 2. When the output screw 802 rotates, it synchronously drives the output bevel gear 806 to rotate. When the output bevel gear 806 rotates, it drives the synchronous screw 503 to rotate through the driven bevel gear 502. When the synchronous screw 503 rotates, the lifting block 504 moves downward. When the lifting block 504 moves downward, it drives the connecting rod 506 to move downward through the lifting plate 505. The connecting rod 506 is in the sliding groove 507 and drives the sliding groove 507 to move, so that the sliding groove 507 drives the rotating plate 508 to rotate around the connecting shaft 509. The connecting shaft 509 moves upward away from the side of the connecting rod 506. At this time, the mechanical support frame 7 can be placed.

[0039] When the mechanical support frame 7 is placed on the top of the test bench 2, the servo motor 801 controls the output screw 802 to reverse. When the output screw 802 reverses, the movable platform 3 drives the pressure mechanism 4 to move toward the test bench 2, and when the pressure mechanism 4 moves, it pushes the mechanical support frame 7 toward the pressure mechanism 4. The pressure mechanism 4 and the fixing mechanism 5 automatically fix the mechanical support frame 7. When the output screw 802 reverses, the driven bevel gear 502 reverses synchronously. At this time, the lifting block 504 drives the lifting plate 505 to move upward. When the connecting rod 506 drives the connecting rod 506 to move upward in the sliding groove 507, the rotating plate 508 moves downward away from the lifting plate 505 and contacts the mechanical support frame 7, thereby pressing the mechanical support frame 7.

[0040] After the mechanical support frame 7 is pressed and fixed, the electromagnet 411 is reversely energized to generate magnetic repulsion between the magnetic plate 412, and the magnetic plate 412 contacts the electromagnet 411. At this time, the through hole in the shielding plate 413 above the magnetic plate 412 coincides with the through hole of the pressure block 409. When the hydraulic rod 402 is started to drive the ejection rod 403 to be ejected, the ejection rod 403 will pass through the through hole of the pressure block 409 and the shielding plate 413. At this time, the ejection rod 403 will press against the side of the mechanical support frame 7 to apply force at a point position.

[0041] When the ejection rod 403 retreats and leaves the baffle plate 413, the electromagnet 411 is energized in the forward direction, and there is a magnetic repulsion force between the electromagnet 411 and the magnetic plate 412. The magnetic plate 412 drives the baffle plate 413 to move upward. At this time, the through hole of the baffle plate 413 and the through hole of the pressure block 409 are staggered with each other. When the ejection rod 403 is ejected again and contacts the baffle plate 413, it will drive the baffle plate 413 to move. When the baffle plate 413 moves, it drives the pressure block 409 to move as a whole toward the mechanical support frame 7. At this time, pressure can be applied to the entire surface of the mechanical support frame 7. When the pressure block 409 moves, it will drive the side connecting block 406 to move and compress the support spring 408. When the ejection rod 403 retracts, the support spring 408 will reset and drive the pressure block 409 to reset.

[0042] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

The moving block (803) synchronously drives the moving platform (3) and the pressure mechanism (4) above the moving platform (3) to move away from the test bench (2). When the output screw (802) rotates, the output bevel gear (806) is synchronously driven to rotate. When the output bevel gear (806) rotates, the synchronous screw (503) is driven through the driven bevel gear (502). ) rotates, and when the synchronous screw (503) rotates, the lifting block (504) moves downward. When the lifting block (504) moves downward, the connecting rod (506) is driven downward through the lifting plate (505). The connecting rod (506) is in the sliding groove (507) and drives the sliding groove (507) to move, so that the sliding groove (507) drives the rotating plate (508) to rotate around the connecting shaft (509). The side of the connecting shaft (509) away from the connecting rod (506) moves upward, and the mechanical support frame (7) can be placed in it at this time; Step S2, when the mechanical support frame (7) is placed above the test bench (2), the servo motor (801) controls the output screw (802) to reverse, and when the output screw (802) reverses, the movable platform (3) drives the pressure mechanism (4) to move toward the test bench (2), and when the pressure mechanism (4) moves, it pushes the mechanical support frame (7) toward the pressure mechanism (4), and the pressure mechanism (4) and the fixing mechanism (5) automatically fix the mechanical support frame (7), and when the output screw (802) reverses, the driven bevel gear (502) is synchronously reversed, and at this time, the lifting block (504) drives the lifting plate (505) to move upward, and when the connecting rod (506) drives the connecting rod (506) to move upward in the sliding groove (507), the rotating plate (508) moves downward away from the lifting plate (505) and contacts with the mechanical support frame (7), thereby pressing the mechanical support frame (7); Step S3, after the mechanical support frame (7) is pressed and fixed, the electromagnet (411) is reversely energized to generate a magnetic repulsive force between the electromagnet (411) and the magnetic plate (412), and the magnetic plate (412) contacts the electromagnet (411). At this time, the through hole in the shielding plate (413) above the magnetic plate (412) coincides with the through hole of the pressure block (409). When the hydraulic rod (402) is started to drive the ejection rod (403) to be ejected, the ejection rod (403) will pass through the through hole of the pressure block (409) and the shielding plate (413). At this time, the ejection rod (403) will press against the side of the mechanical support frame (7) to apply force at a point position; Step S4, when the ejector rod (403) retreats and leaves the shielding plate (413), the electromagnet (411) is energized in the forward direction, and there is a magnetic repulsion force between the electromagnet (411) and the magnetic plate (412), and the magnetic plate (412) drives the shielding plate (413) to move upward. At this time, the through hole of the shielding plate (413) and the through hole of the pressure block (409) are staggered with each other, and the ejector rod (403) will be ejected again and contact the shielding plate (413) when it will bring The movable shielding plate (413) moves, and when the shielding plate (413) moves, it drives the pressure block (409) to move as a whole toward the mechanical support frame (7). At this time, pressure can be applied to the entire surface of the mechanical support frame (7). When the pressure block (409) moves, it drives the side connection block (406) to move and compress the support spring (408). When the ejection rod (403) retracts, the support spring (408) will reset and drive the pressure block (409) to reset.
