DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Such as Figures 1 to 2As shown in the figure, a strength testing device for concrete components has been improved through a series of design modifications on the structure of the original single-functional equipment. The improved testing device can conduct compressive strength and tensile strength tests on concrete components. At the top of the chassis 1 of the testing device, there is a test bench 11. On the test bench 11, there is a movable test base 2. At the top of the test base 2, there is a base fixture detachably connected for clamping and limiting the concrete component. At the same time, on both sides of the top of the test bench 11, there are parallel first side frames 4 and second side frames 5. Between the first side frame 4 and the second side frame 5, there is a test movable top seat 3. The test movable top seat 3 is movably arranged above the test base 2. One end of the test movable top seat 3 close to the test base 2 is detachably connected with a top seat fixture for clamping and limiting the concrete component. By removing the base fixture and the top seat fixture, the compressive strength test of the concrete component placed on the test base 2 can be carried out by controlling the test movable top seat 3. After installing the base fixture and the top seat fixture, the concrete component is clamped and limited between the base fixture and the top seat fixture, and then by controlling the test movable top seat 3 to drive the top seat fixture to move, the tensile strength test of the concrete component can be carried out.

[0027] Furthermore, in the embodiment, one end of the test base 2 close to the test bench 1 is connected with a rotating pedestal. At the end of the rotating pedestal away from the test base 2, there is a lifting and translation structure for driving the rotating pedestal to move up and down. The lifting and translation structure includes a hydraulic lifting rod 21, and the hydraulic lifting rod 21 is arranged in the chassis 1. One end of the hydraulic lifting rod 21 can move up and down through the test bench 11, and the end is fixedly connected to the bottom end of the rotating pedestal. The other end of the hydraulic lifting rod 21 is installed and connected to the chassis 1 through a fixed bracket. At the same time, the tops of the first side frame 4 and the second side frame 5 are fixedly connected through a cross beam. A first movable structure is installed and connected on the first side frame 4, and one side end of the test movable top seat 3 is used to be connected to the first movable structure. And a second movable structure is installed and connected on the second side frame 5, and the other side end of the test movable top seat 3 is used to be connected to the second movable structure. By controlling the synchronous lifting and moving of the first movable structure and the second movable structure, the test movable top seat 3 can be driven to move up and down.

[0028] When it is necessary to conduct a compressive strength test on a concrete member, the base fixture and the top seat fixture are removed at this time. By controlling the synchronous downward movement of the first movable structure and the second movable structure, it is used to drive the test movable top seat 3 to move downward, so as to conduct a compressive strength test on the concrete member placed on the test base 2; when it is necessary to conduct a tensile strength test on a concrete member, the base fixture and the top seat fixture are installed at this time. The concrete member is clamped and limited on the base fixture and the top seat fixture, and then by controlling the synchronous upward movement of the first movable structure and the second movable structure, it is used to drive the test movable top seat 3 to drive the top seat fixture to move upward, so as to conduct a tensile strength test on the concrete member.

[0029] Further, in the embodiment, the first movable structure provided includes a first movable lead screw 41; the top end of the first movable lead screw 41 is rotatably connected to the top end of the first side frame 4 through a bearing; the top end of the first movable lead screw 41 rotatably passes through the test bench 11 through a bearing, and the end is connected to a first lead screw machine 42. The first lead screw machine 41 is arranged in the chassis 1, and the outer shell of the first lead screw machine 42 is fixedly connected to the inside of the chassis 1 through a bracket; one side end of the test movable top seat 3 close to the first movable lead screw 41 is connected with a first movable guide seat, and the first movable guide is arranged in a liftable connection with the first movable lead screw 41. At the same time, the second movable structure provided includes a second movable lead screw 51; the top end of the second movable lead screw 51 is rotatably connected to the top end of the second side frame 5 through a bearing; the top end of the second movable lead screw 51 rotatably passes through the test bench 11 through a bearing, and the end is connected to a second lead screw machine 52. The second lead screw machine 52 is arranged in the chassis 1, and the outer shell of the second lead screw machine 52 is fixedly connected to the inside of the chassis 1 through a bracket; one side end of the test movable top seat 3 close to the second movable lead screw 51 is connected with a second movable guide seat, and the second movable guide is arranged in a liftable connection with the second movable lead screw 51. Designed in this way, when it is necessary to control the lifting and moving of the test movable top seat 3, by synchronously controlling the start of the first lead screw machine 42 and the second movable lead screw 51, at this time the first lead screw machine 42 drives the first movable lead screw 41 connected to its output end to "rotate", and the second lead screw machine 52 drives the second movable lead screw 51 connected to its output end to rotate. Thus, the first movable lead screw 41 and the second lead screw machine 52 rotate synchronously, driving the test movable top seat 3 connected to the first movable lead screw 41 through the first movable guide seat and the second movable lead screw 51 through the second movable guide seat to "move up and down", thereby facilitating the implementation of strength (tensile and compressive, etc.) tests on the concrete member placed between the test movable top seat 3 and the test base 2. This test device can not only overcome the defect of the original device's single test, but also facilitate the test through the test device, saving test time and cost.
