[0024] Example See attached Figures 1-4This embodiment provides a movable trench-anchored base 1, including a base 1 and several sets of liftable and movable components, suitable for fixing and moving test components during seismic testing. The base 1 adopts a three-layer steel plate structure design, with the three layers of steel plates arranged in parallel, from top to bottom as an upper layer, middle layer, and lower layer. The three layers of steel plates are fixedly connected by several steel pipes to form an overall frame. The two ends of the steel pipes are welded to adjacent steel plates, and the weld joints are ground to ensure a smooth transition, thereby improving the overall rigidity and deformation resistance of the base 1. It can withstand the longitudinal and transverse loads generated during seismic testing, avoiding structural deformation of the base 1 due to excessive test loads. Several tooling connection bolt holes 4 are evenly distributed on each of the three layers of steel plates, arranged in a matrix pattern along the transverse and longitudinal directions of the steel plates. This distribution allows the base 1 to adapt to seismic test components or tooling of different sizes and types. By selecting different positions of the tooling connection bolt holes 4, the fixing position of the test component can be flexibly adjusted to meet diverse testing needs. The tooling connection bolt 6 is installed in the tooling connection bolt hole 4. During the test, the tooling connection bolt 6 is passed through the tooling connection bolt hole 4 on the base 1 and threadedly connected to the preset mounting hole of the test component or tooling and tightened. This achieves a detachable and fastened connection between the test component or tooling and the base 1, with high connection strength and convenient assembly and disassembly.
[0025] In this embodiment, several anchor bolt holes 3 are evenly spaced laterally along the middle of each of the three steel plates. The diameter of the anchor bolt holes 3 is larger than the diameter of the tooling connection bolt holes 4. Anchor bolts 5 are installed in the anchor bolt holes 3. When the base 1 moves above the trench, the anchor bolts 5 pass through the anchor bolt holes 3 and are threadedly connected to the pre-embedded nuts in the trench of the test site. By tightening the anchor bolts 5, the base 1 can be firmly anchored to the trench. Since the anchor bolt holes 3 are located in the middle of the steel plates, the anchoring force can be evenly distributed in the central area of the base 1, effectively improving the horizontal resistance of the base 1, avoiding horizontal displacement or shaking of the base 1 during the test, and ensuring the stability of the test.
[0026] In this embodiment, several sets of liftable and movable components are evenly installed on the base 1. The number can be adjusted according to the weight of the base 1. Each set includes a connecting seat, a telescopic cylinder, and rollers 2. The connecting seat can be a rectangular steel plate structure with several through holes. The diameter of the through holes is the same as the diameter of the tooling connection bolt holes 4. During installation, the connecting seat is placed against the lower surface of the middle layer steel plate, aligning the through holes on the connecting seat with the corresponding tooling connection bolt holes 4 on the middle layer steel plate. Then, the tooling connection bolts 6 are passed through the through holes and tooling connection bolt holes 4 and tightened to achieve detachable fixation between the connecting seat and the middle layer steel plate. This connection method is not only reliable but also facilitates maintenance or replacement of the liftable and movable components in the future. The cylinder body of the telescopic cylinder is fixedly connected to the lower surface of the connecting seat by bolts. The telescopic end of the cylinder is vertically downward, and the end of the telescopic end is connected to the rollers 2 by a bushing. The axle of the rollers 2 passes through the bushing of the telescopic end of the telescopic cylinder and is limited by a retaining ring to ensure that the rollers 2 can rotate flexibly. Roller 2 can be a universal wheel with braking function. Its wheel body is made of high-strength rubber material, which has good load-bearing capacity and can reduce friction noise with the ground when moving.
[0027] In this embodiment, a storage hole is provided on the lower steel plate corresponding to the position of the liftable movable component. The size of the storage hole is slightly larger than the outer diameter of the roller 2. When the telescopic cylinder is in the retracted state, the roller 2 can be completely stored in the space between the middle steel plate and the lower steel plate. At this time, the lower surface of the lower steel plate can be in complete contact with the ground, ensuring the stability of the base 1 when it is placed. When the telescopic cylinder is extended, the roller 2 passes through the storage hole and extends under the lower steel plate until the roller 2 completely supports the base 1, causing the lower steel plate to detach from the ground. At this time, the base 1 can be moved flexibly through the roller 2.
[0028] In this embodiment, a push rod is welded to the middle of one side of the base 1, and its two ends are welded and fixed to the sides of the upper and middle steel plates to form a triangular support structure. The operator can control the movement direction of the base 1 by pushing the push rod, and with the steering function of the casters, the base 1 can flexibly adjust its movement path.
[0029] The working principle of this utility model is as follows: When it is necessary to move the base 1, the telescopic cylinder is activated to extend it. The roller 2 extends out of the lower steel plate through the storage hole and supports the base 1. The operator pushes the push rod, and the universal wheels move the base 1 to the target position directly below the multi-channel combined loading frame. After reaching the position, the telescopic cylinder is controlled to retract, and the roller 2 is stored between the middle steel plate and the lower steel plate. The lower steel plate contacts the ground, and then the anchor bolts 5 are passed through the anchor bolt holes 3 and anchored to the ground groove, completing the fixation of the base 1. The seismic test component or tooling is placed on the upper steel plate of the base 1. The tooling connection bolt holes 4 are selected according to the size of the component, and the component is fastened to the base 1 through the tooling connection bolts 6. Then, the component or tooling is connected and fixed to the multi-channel combined loading frame, and the seismic test can be carried out. After the test is completed, if the component and base 1 need to be removed as a whole, the connecting bolts between the component and the loading frame and the anchor bolts 5 can be removed. The telescopic cylinder is controlled to extend so that the roller 2 supports the base 1 and pushes the base 1 to move the component away from the test area. If only the component is replaced, it is only necessary to remove the connecting bolts between the component and the loading frame and the tooling connecting bolts 6 between the component and the base 1. After removing the old component, the new component is replaced. The base 1 remains anchored to the ground trench. There is no need to repeatedly adjust the position of the base 1, which improves the test efficiency.
[0030] This utility model achieves convenient movement and stable fixation of the base 1 through a liftable and movable component. Combined with the design of multiple bolt holes, it enhances adaptability. The two post-test operation modes can flexibly meet different test requirements, effectively improving the operation efficiency and stability of the seismic test.
