Description

Technical Field

[0001] This utility model belongs to the technical field of testing equipment, and relates to a sliding hinge support for testing and testing equipment. Background Technology

[0002] In structural model tests, loading tests, and bridge teaching experiments, bearings are key components for transferring loads, controlling boundaries, and simulating stress states. Common bearing types include fixed bearings, hinged bearings, and sliding bearings, which respectively provide rigid constraints, rotational freedom, and / or horizontal sliding degrees of freedom. However, these common bearings have limited functions and lack flexible switching capabilities.

[0003] In practical engineering or experimental teaching, it is often necessary to simulate sliding hinge supports with rotatable and sliding boundary conditions to adapt to different working conditions, loading schemes, or thermal expansion and contraction deformation. Commercially available sliding hinge supports achieve rotation and sliding through the cooperation of rollers and elongated slots. Specifically, the rollers can rotate relative to the elongated slots of the double-ear plates, and sliding is achieved by the rollers moving within the elongated slots of the double-ear plates. While this type of sliding hinge support is commonly used in practical engineering, its rotational and sliding friction is relatively high, affecting experimental accuracy when used in testing equipment. Furthermore, the sliding distance of the rollers relative to the elongated slots is short, and flexible switching is not possible, making it unsuitable for testing.

[0004] Therefore, developing a sliding hinge support that has both rotation and sliding functions and can ignore friction in experiments has significant scientific research application value. Summary of the Invention

[0005] The purpose of this invention is to provide a sliding hinge support and testing equipment for testing, which is suitable for testing and can realize the functions of rotation and sliding.

[0011] A brake clamp is connected to the slider. The brake clamp is equipped with a clamping drive mechanism and a clamping block. Under the drive of the clamping drive mechanism, the clamping block can abut against the linear slide rail, or the clamping block can disengage from the linear slide rail.

[0012] Rotate the support frame, which is mounted on the slider;

[0013] The rotating platform is rotatably connected to the rotating support frame via bearings.

[0014] Preferably, the clamping drive mechanism includes a slide groove and a lead screw.

[0016] The clamping blocks are configured as two, with the positive and negative external threads of the screw thread each engaging with the threaded holes of one clamping block.

[0017] Preferably, a handle is provided at one end of the lead screw.

[0052] Example 1

[0053] like Figures 1 to 20 As shown, the experimental sliding hinge support in this embodiment includes a base plate 1, a linear slide rail 2, a slider 3, a brake clamp 4, a rotating support frame 5, and a rotating table 6.

[0054] The base plate 1 has an assembly hole at its edge, and a first assembly bolt 11 is fitted into the assembly hole to assemble the entire test sliding hinge support onto the test equipment.

[0055] The linear slide rail 2 is located at the middle position on the upper surface of the base plate 1. The linear slide rail 2 is assembled and connected to the base plate 1 by the second mounting bolt 21. The second mounting bolt 21 at both ends of the linear slide rail 2 in the length direction can act as limit posts to prevent the slider 3 from continuing to slide, thus limiting the extreme position of the slider 3 relative to the linear slide rail 2.

[0056] The slider 3 is slidably fitted onto the linear slide rail 2. The linear slide rail 2 has limiting grooves on both sides in the width direction, and the slider 3 has limiting protrusions on both sides in the width direction, with the protrusions fitting into the limiting grooves. This ensures that the slider 3 is in a limiting fit with the linear slide rail 2, and that the slider 3 can slide along the length direction of the linear slide rail 2.

[0057] The brake clamp 4 is connected to the slider 3. The brake clamp 4 is provided with a clamping drive mechanism and a clamping block 41. Under the drive of the clamping drive mechanism, the clamping block 41 can abut against at least one side of the linear slide rail 2 in the width direction, or, under the drive of the clamping drive mechanism, the clamping block 41 can disengage from the linear slide rail 2.

[0058] The rotating support frame 5 is assembled and connected to the slider 3 and the brake clamp 4 via screws 50, so that the brake clamp 4 is connected to the slider 3. This makes the entire support structure compact and facilitates the miniaturization design of the support.

[0059] The clamping drive mechanism includes a slide groove 42, a lead screw 43, and a handle 44. The slide groove 42 is formed on the brake block 4, and the upper end of the clamping block 41 is slidably fitted into the slide groove 42. The clamping block 41 has a threaded hole, and the lead screw 43 is rotatably connected to the brake block 4, engaging with the threaded hole. A support plate 40 is provided at one end of the brake block 4, and one end of the lead screw 43 is rotatably connected to the support plate 40. Thus, rotating the lead screw 43 forward causes the clamping block 41 to approach and abut against the linear slide rail 2, and rotating the lead screw 43 in the reverse direction causes the clamping block 41 to disengage from the linear slide rail 2. After the clamping block 41 approaches and abuts against the linear slide rail 2, the slider 3 is locked to the linear slide rail 2. After the clamping block 41 disengages from the linear slide rail 2, the lock between the slider 3 and the linear slide rail 2 is released. This allows for flexible switching between "sliding + rotation" boundary conditions and "rotation" boundary conditions.

[0060] The lead screw 43 is configured as a counter-rotating lead screw, with a forward external thread and a reverse external thread at each end. Two clamping blocks 41 are configured, each with a threaded hole in one of the clamping blocks 41, the forward and reverse external threads of the lead screw respectively engaging with the threaded hole of the clamping block 41. Thus, rotating the lead screw 43 forward causes the two clamping blocks 41 to approach and abut against the linear slide rail 2, while rotating the lead screw 43 in the reverse direction causes the two clamping blocks 41 to disengage from the linear slide rail 2. This ensures a more secure locking between the slider 3 and the linear slide rail 2.

[0061] A handle 44 is provided at one end of the lead screw 43. The tester can manually crank the handle 44 to drive the lead screw 43 to rotate in the forward or reverse direction.

[0062] A rotating support frame 5 is mounted on the slider 3, and a rotating platform 6 is rotatably connected to the rotating support frame 5 via a bearing 61. Specifically, ear plates 51 are provided on opposite sides of the rotating support frame 5, arranged vertically, and a hinge shaft 52 is connected between the ear plates 51 on opposite sides. The rotating platform 6 is rotatably connected to the hinge shaft 52 via the bearing 61. A bearing mounting hole 60 is provided on the rotating platform 6, and retaining rings 7 are provided on both sides of the outer ring of the bearing 61. The retaining rings 7 limit the bearing 61 to prevent it from falling out of the bearing mounting hole 60. A shaft hole 511 is provided on the ear plate 51, and the hinge shaft 52 is fitted into the shaft hole 511. The inner ring of the bearing 61 is fitted into the hinge shaft 52, and a retaining ring 7 is provided at the outer end of the hinge shaft 52 to limit the hinge shaft 52 to prevent it from falling out of the shaft hole 511.

[0063] Example 2

[0064] A testing apparatus, the testing apparatus comprising the sliding hinge support for testing as described in Example 1.

[0065] The present invention has been described in detail above with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the experimental sliding hinge support and experimental equipment of this utility model. The experimental sliding hinge support of this utility model, when applied to experimental equipment, achieves long-distance sliding by sliding the slider 3 in conjunction with the linear slide rail 2, and achieves rotation by rotating the rotating table 6 relative to the rotating support frame 5 via the bearing 61. This effectively reduces frictional resistance during sliding and rotation, better simulates the actual stress state of the structural boundary, and improves experimental accuracy. During the experiment, the clamping block 41 abuts against the linear slide rail 2, locking the slider 3 and the linear slide rail 2, thus enabling flexible switching between "sliding + rotation" boundary conditions and "rotation" boundary conditions. It is widely applicable to structural model experiments, loading tests, and bridge teaching experiments.

[0066] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
