Description
Technical Field
[0001] The utility model relates to the technical field of reaction frames, in particular to a reaction frame assembly. Background Art
[0002] The reaction frame mainly consists of a cross beam, columns, a base, a lifting system, a hydraulic system, adjusting pads, etc. It is mainly used for the calibration of jacks and can also be used for the compressive testing of various materials such as large concrete components and large workpieces.
[0003] The existing reaction frames have the following problems:
[0004] 1. There is no guiding component on the existing reaction frame for guiding the output end of the hydraulic device. Without a guiding device, the hydraulic device is prone to hydraulic fluid leakage after being subjected to non-axial forces. Once the hydraulic fluid leakage occurs, the staff needs to repair the reaction frame, which reduces the detection efficiency to a certain extent.
[0005] 2. The output end of the existing hydraulic device usually uses a spherical hinge or a fixed hinge support to achieve force transmission. Among them, although the spherical hinge allows the test piece to rotate freely in multiple directions, the processing requirements of the spherical hinge are high, increasing the manufacturing cost.
[0006] Therefore, it is necessary to design a reaction frame assembly with tilt limitation for the output end of the hydraulic device and cost reduction of the equipment. Summary of the Utility Model
[0007] In order to solve the above problems, the utility model proposes a reaction frame assembly to more precisely solve the above problems.

[0014] Further, in the present utility model, the hydraulic loading assembly includes a hydraulic cylinder, an output end connected to the hydraulic rod and performing lifting, and a force sensor connected to the conveying end. A bearing mounting plate is connected to the bottom of the force sensor, a spherical roller thrust bearing is connected to the bottom of the bearing mounting plate, a hoisting plate is disposed below the spherical roller thrust bearing, lifting rings are connected to both sides of the hoisting plate, and the other ends of the lifting rings are connected to the bearing mounting plate.
[0015] Further, in the present utility model, at least one box seat is disposed on the top of the lower crossbeam, and a hinge support is disposed on the box seat.
[0016] Further, in the present utility model, the hinge support includes a seat body, a radian groove formed in the seat body, and a radian block disposed in the radian groove and concentric with the radian groove. A placement plate is fixedly installed on the top of the radian block.

The setting of the guiding assembly can limit the position and moving position of the output end of the hydraulic loading assembly.

In addition, the setting of the guide component 3 can also limit the moving position of the output end 22 of the hydraulic loading component 2, thereby making the loading position of the output end 22 of the hydraulic loading component 2 on the specimen more accurate.
[0034] Specifically, refer to Figure 2 and Figure 3 The guide assembly 3 includes a guide plate 31 connected to the output end 22 of the hydraulic loading assembly 2, an inner hole 32 provided on the guide plate 31 and used for the output end 22 of the hydraulic loading assembly 2 to pass through, and a guide foot 33 provided in the circumferential direction of the guide plate 31, and the guide foot 33 is connected to the inner side of the reaction frame 1 through the sliding assembly 4;
[0035] The inner hole 32 is provided to allow the output end 22 of the hydraulic loading assembly 2 to pass through, and to achieve the connection between the guide plate 31 and the output end 22 of the hydraulic loading assembly 2. The guide foot 33 cooperates with the sliding assembly 4 to fix the four sides of the guide plate 31, thereby limiting the position of the output end 22 of the hydraulic loading assembly 2. The inner hole 32 and the guide plate 31 are provided to limit the left and right movement range of the output end 22 of the hydraulic loading assembly 2, thereby avoiding the occurrence of tilting or bending of the output end 22 of the hydraulic loading assembly 2.
[0036] Preferably, reference Figure 2 and Figure 4 The sliding assembly 4 includes a sliding rail 41 connected to the inner side of the reaction force frame, and a slider 42 connected to the guide foot 33 is slidably matched outside the sliding rail 41; the setting of the sliding assembly 4 can make the guide plate 31 move upward or downward synchronously with the movement of the output end 22 of the hydraulic loading assembly 2, thereby ensuring the position limitation work of the output end 22 of the hydraulic loading assembly 2, and at the same time, the existence of the sliding assembly 4 can make the up and down movement of the output end 22 of the hydraulic loading assembly 2 more precise.
[0037] In this embodiment, referenceFigure 3 The connection mode between the guide plate 31 and the output end 22 of the hydraulic loading assembly 2 is fixed connection.

On the output end 22 of the hydraulic loading assembly 2, second fixing holes 36 are provided that are in alignment with the positions of the number of first fixing holes 35. A fixing member (not shown in the figure) is connected within the first fixing holes 35 and the second fixing holes 36;
[0038] Optionally, the fixing member includes a screw;

When the placement plate 64 rotates, the specimen will be driven to rotate synchronously. That is, when the specimen is loaded with force, after the specimen deforms under force, the presence of the radian block 63 and the radian groove 62 allows the specimen to rotate within a certain range;
