Background technique:

Due to the improvement of test requirements and the need to complete multi-parameter tests in a certain limited space at one time, instrument manufacturers are increasingly inclined to integrate multiple mechanical parameters in the same device or integrate multiple devices to meet the needs of limited space. In order to carry out a certain mechanical test, it is necessary to have a corresponding bearing device. However, there are few load-bearing devices on the market that are specially used to place large-scale mechanical testing instruments, and the current devices used for tensile tests are stretched in one direction, and there is no device that can stretch in both directions up and down at the same time, or provide corresponding power source.

The two are integrated and powered by an external hydraulic power unit; the surface of the multi-functional platform contains two tracks; Composed of a drive rod and an adjustable locking device, the hydraulic drive rod is powered by an external hydraulic power unit to achieve vertical expansion and contraction; Composed of grooves and hexagonal bolts, the hexagonal bolts can move along the longitudinal and transverse cross-shaped grooves to lock the equipment placed on the surface of the second-level platform; the supporting columns are made of high-strength materials, supporting The entire structure, and vibration isolation;

The imported platform module is composed of the second base and the mobile platform. The second base is composed of two guide rails. The guide rail moves, and the distance between a pair of pulleys in the horizontal direction of the mobile platform is consistent with the distance between the two rails above the first-stage hydraulic lifting platform. The size of the pulleys corresponds to the track on the first-stage hydraulic lifting platform. move;

The fixed module is composed of a flexible locking device. The flexible locking device is located on the upper surface of the first-stage hydraulic lifting platform and is distributed symmetrically in the lateral direction. The flexible locking device is composed of a support base, a small hydraulic drive rod and a flexible arc-shaped contact head. The flexible arc-shaped The contact head is connected with a small hydraulic drive rod, the small hydraulic drive rod can be stretched horizontally, and the flexible arc-shaped contact head can be deformed to a certain extent so as to be close to the object to be contacted.

Compared with the existing caps, the present invention has the following advantages:

1. Provide the corresponding conditions for the tensile test or compression strength test, and combine the flexible locking device on the same platform so that the placed object and the platform can keep rising or falling in the vertical direction at the same time, which can be compressed or pulled ;

2. Corresponding multi-stage caps can be placed to integrate instruments and equipment.

Detailed ways:

Figure 1 is a three-dimensional view of the present invention. As shown in Figure 1, the present invention is a multi-stage open main platform for large-scale mechanical tests, which is composed of a multi-level main platform module A, an introduction platform module B and a fixed module C. Each module is relatively independent and can be used for Integrate more instruments to work together.

Figure 2 is a structural diagram of the main platform module. As shown in Figure 2, the multi-stage main platform module A is composed of a first base A1, a first-stage hydraulic lifting platform A2, a second-level platform A3, a top cover A4 and a support column A5. The support column A5 is composed of high-strength materials, supporting the entire structure and isolating vibrations. As shown in Figure 3, the first-stage hydraulic lifting platform A2 is composed of a hydraulic lifting column A2-1 and a multifunctional platform A2-2. , the rising and falling power is provided by an external hydraulic power unit; the surface of the multifunctional platform A2-2 contains two rails A2-3. The fixed module C is composed of a pair of flexible locking devices C1, which are located on the upper surface of the first-stage hydraulic lifting platform A2 and distributed symmetrically in the lateral direction. As shown in Figure 4, the flexible locking device C1 is composed of a support base C1-1, a small hydraulic drive rod C1-2 and a flexible arc-shaped contact head C1-3, and the flexible arc-shaped contact head C1-3 and the small hydraulic drive rod C1- 2 connections, the small hydraulic drive rod C1-2 can expand and contract in the horizontal direction according to actual needs, and the flexible arc-shaped contact head C1-3 is deformed to a certain extent, so as to be close to the object to be contacted, so that the object and the first-stage hydraulic lifting platform A2 forms a whole, so that it can provide upward or downward power to the instruments and equipment entering the platform. As shown in Figure 5, the second-stage cap A3 is composed of a hydraulic drive rod A3-1 at the bottom and an adjustable locking device A3-2 distributed on the surface of the cap. unit to realize the expansion and contraction in the vertical direction. When the equipment on the first-stage hydraulic lifting platform A2 needs the platform to provide tension or pressure from the upper part of the equipment, the hydraulic drive rod A3-1 can be connected with the equipment to realize Power is provided for upward or downward movement from the top of the device. The adjustable locking device A3-2 is inlaid on the upper surface of the second stage cap, and consists of a cross-shaped groove A3-2-1 and the corresponding hexagonal bolt A3-2-2, and the bolt A3-2-2 can be The cross-shaped groove A3-2-1 moves in two directions and can be used to lock the equipment placed on the platform surface as required.
