[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-Figure 3 As shown, a preferred embodiment of the utility model proposes a compressive testing device for an elevator straight beam, which mainly includes a convex base 1, an n-shaped frame 2 fixedly installed between the two sides of the middle of the convex base 1, a telescopic cylinder 3 installed in the middle of the top of the n-shaped frame 2, and an extrusion block 4 fixedly installed at the telescopic end of the telescopic cylinder 3 located on the inner side of the n-shaped frame 2, wherein two installation slots 5 are symmetrically opened on the top of the convex base 1, a pair of moving blocks 6 are installed inside each installation slot 5, and fixed clamping blocks 7 are installed on the opposite sides of the upper parts of the two pairs of moving blocks 6;

[0019] A mounting plate 8 is fixedly installed at the telescopic end of the telescopic cylinder 3 located on the inner side of the n-shaped frame 2, and transmission fixtures 9 are fixedly installed on both sides of the bottom of the mounting plate 8. The two transmission fixtures 9 are respectively connected to the two pairs of moving blocks 6 for transmission. A round block 25 is fixedly installed at the telescopic end of the telescopic cylinder 3, and reinforcing rods 26 are fixedly connected between the surface of the round block 25 and the four corners of the top of the mounting plate 8, thereby effectively maintaining the stability of the pressurization of the mounting plate 8.

[0020] refer to Figure 3An inner cavity 10 is opened in the middle of the upper part of the convex base 1, and a plurality of through grooves 11 connected with the inner cavity 10 are opened at equal distances on the top of the convex base 1. A lifting plate 12 is installed on the top of the inner cavity 10, and a plurality of pairs of fixed blocks 13 located inside the through groove 11 are installed at equal distances on the top of the lifting plate 12. A roller 14 is fixedly installed between the upper parts of a pair of fixed blocks 13 inside the through groove 11, so that the elevator straight beam can be effectively placed and moved; the elevator straight beam is placed between the surfaces of the roller 14, and then the elevator straight beam is moved by the roller of the roller 14, so as to adjust the detection position of the elevator straight beam.

[0021] refer to Figure 3 Two ends of the lower part of the inner cavity 10 are rotatably connected with bidirectional threaded shafts 15, and both sides of the two bidirectional threaded shafts 15 are threadedly connected with moving sleeves 16. The top of the moving sleeve 16 and the bottom of the lifting plate 12 are rotatably connected with adjustment blocks 17, so that the roller 14 can be effectively adjusted to move the elevator straight beam to the top of the convex base 1 for placement, so that the elevator straight beam can stably perform pressure resistance testing.

[0022] like Figure 3 As shown, both ends of the two bidirectional threaded shafts 15 extend to the inside of the two mounting grooves 5 respectively, and the ends of the bidirectional threaded shafts 15 located inside the mounting grooves 5 are fixedly connected with threaded shafts 18. The two threaded shafts 18 on the same bidirectional threaded shaft 15 are symmetrically arranged, and the lower part of the moving block 6 is threadedly connected to the threaded shaft 18. One end of the threaded shaft 18 extends to the side of the convex base 1 and is fixedly connected with a gear 19, so that the lifting plate 12 can be effectively adjusted.

[0023] When the four threaded shafts 18 rotate synchronously, the two bidirectional threaded shafts 15 will rotate, and the rotation of the two bidirectional threaded shafts 15 will cause the two movable sleeves 16 on their surfaces to move back to each other. The movement of the movable sleeves 16 will drive the lifting plate 12 to move downward through the four adjustment blocks 17, and the downward movement of the lifting plate 12 will drive the fixed block 13 and the roller 14 to move downward, and finally the roller 14 will move down to the inside of the through groove 11, so that the elevator straight beam placed on the surface of the through groove 11 can be stably placed on the top of the convex base 1.

[0024] like Figure 3 As shown, a sleeve 20 is fixedly installed on the upper part of the moving block 6, and a T-shaped block 21 is movably inserted at one end of the sleeve 20.

[0025] When the four threaded shafts 18 rotate synchronously, the moving block 6 on the surface thereof will move toward the roller 14, so that the moving block 6 drives the sleeve 20, the T-shaped block 21, the strong spring 22 and the fixed clamping block 7 to move toward the elevator straight beam, and finally the four fixed clamping blocks 7 effectively clamp and fix the convex base 1.

[0026] like Figure 2 As shown, the transmission fixture 9 includes a vertical plate 23, two vertical plates 23 are fixedly connected to the two sides of the bottom of the mounting plate 8, and racks 24 are fixedly installed at both ends of the two vertical plates 23, and the four racks 24 are respectively located above the four gears 19, so that the transmission can be effectively performed; vertical slide grooves 27 are opened in the middle of both sides of the inside of the n-shaped frame 2, and inverted T-shaped sliders 28 are slidably installed inside the two vertical slide grooves 27, and one end of the two inverted T-shaped sliders 28 is respectively fixedly connected to the lower part of one side of the vertical plate 23, so that the vertical plate 23 can be stably and effectively moved;

[0027] By starting the telescopic cylinder 3 to extend, the telescopic cylinder 3 drives the mounting plate 8 and the extrusion block 4 to move downward and toward the elevator straight beam. The downward movement of the mounting plate 8 drives the two vertical plates 23 and the four racks 24 to move downward, so that the four racks 24 transmit and rotate the four gears 19, and the rotation of the four gears 19 causes the four threaded shafts 18 to rotate synchronously; finally, the extrusion block 4 pressurizes the top of the elevator straight beam to perform a compression test, and as the mounting plate 8 and the extrusion block 4 continue to move downward, the strong spring 22 is compressed, so that the four fixing clamps 7 effectively clamp and fix the convex base 1.

[0028] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
