DETAILED DESCRIPTION

[0023] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0024] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a force-transmitting steel post-casting strip detection device.

[0025] See also Figure 1 - Figure 6 A force-transmitting steel post-casting strip detection device comprises a detection rod 1, a hardness tester 2 movably installed at the bottom front end of the detection rod 1, and a connecting block 3. A fixing rod 101 is fixedly installed at the front end of the detection rod 1, a stretching rod 102 is movably installed inside the fixing rod 101, a first spring 103 is sleeved and installed on the outer side of the stretching rod 102, a baffle 104 is fixedly connected to the outer side of the stretching rod 102 and is located at the bottom of the first spring 103, a connecting rod 105 is rotatably connected between the bottom of the stretching rod 102 and the connecting block 3, a rotating rod 106 is rotatably installed inside the top of the stretching rod 102, a first through slot 107 is provided at the front end of the rotating rod 106, a first limiting rod 108 fixed to the front end of the rotating rod 106 is slidably installed inside the first through slot 107, and a second through slot 109 is provided on the top of the fixing rod 101.

[0026] Specifically, the elastic force of the first spring 103 acts on the baffle 104 to keep the hardness tester 2 in a vertical state, and the first limit rod 108 is driven by the rotating rod 106 to keep it horizontal to limit the stretching rod 102, so that the hardness tester 2 can be fixed in a vertical state, so that the hardness tester 2 will not rotate when it touches the horizontally placed force transmission steel downward. When the first limit rod 108 is driven by the rotating rod 106 to keep it vertical, the first limit rod 108 can pass through the second through groove 109, and then the hardness tester 2 can be pulled to rotate to a horizontal state through the stretching rod 102 and the connecting rod 105, so as to test the supporting strength of the vertically placed force transmission steel, thereby solving the problem that the force transmission steel with different installation methods is inconvenient to test.

[0027] Further, the hardness tester 2 is movably mounted on the front end of the connecting block 3, the connecting block 3 is rotatably connected to the bottom of the detection rod 1, the rear end of the hardness tester 2 is fixedly mounted with a connecting frame 201, the bottom of the front end of the connecting block 3 is provided with a slot 301, and the rear end of the connecting frame 201 extends to the inside of the slot 301;

[0028] Furthermore, the rear end of the connecting frame 201 is evenly fixed with a supporting block 202, and the rear end of the supporting block 202 is fixedly connected to a rubber pad and closely fits with the front end of the connecting block 3;

[0029] Specifically, the hardness tester 2 slides into the interior of the slot 301 through the rear end of the connecting frame 201, so that the hardness tester 2 is installed at the front end of the connecting block 3. At this time, the rubber pad at the rear end of the support block 202 contacts the front end of the connecting block 3, so that the hardness tester 2 will not shake when installed at the front end of the connecting block 3, thereby making the hardness tester 2 more stably installed.

[0030] Furthermore, a second limiting rod 302 is movably installed inside the cavity of the connecting block 3, and the second limiting rod 302 extends into the circular hole inside the connecting frame 201. A second spring 303 is fixedly installed inside the cavity of the connecting block 3, and the second spring 303 is fixedly connected to the top end of the second limiting rod 302;

[0031] Furthermore, a third through slot 304 is provided at the rear end of the connection block 3, and the third through slot 304 is connected to the cavity inside the connection block 3, and a shift block 305 is slidably installed inside the third through slot 304, and the shift block 305 is fixedly connected to the top end of the second limiting rod 302;

[0032] Specifically, by moving the shift block 305 to slide upward inside the third through slot 304, the second limiting rod 302 slides upward inside the cavity of the connecting block 3. At this time, the second spring 303 is squeezed to generate elastic force. When the rear end of the connecting frame 201 slides into the interior of the slot 301, due to the elastic force of the second spring 303, the bottom of the second limiting rod 302 slides into the circular hole inside the connecting frame 201 to limit the connecting frame 201, so that the connecting frame 201 is fixedly installed inside the slot 301, so that the hardness tester 2 can be more firmly installed at the front end of the connecting block 3 to perform strength testing on the force-transmitting steel.

[0033] Furthermore, the detection rod 1 includes a handle 4 and a pull rod 5 movably mounted on the top of the fixed rod 101, the handle 4 is fixedly mounted on the top of the detection rod 1, and the pull rod 5 is fixedly connected to both sides of the top of the stretching rod 102;

[0034] Specifically, by holding the handle 4, it is convenient to extend the detection rod 1 into the interior of the post-cast strip, which is beneficial for the staff to exert force downward to make the hardness tester 2 perform strength testing on the force-transmitting steel. By holding the pull rod 5, it is convenient to pull the stretching rod 102 upward, so that the hardness tester 2 can be easily pulled to a horizontal position to perform strength testing on the vertically placed force-transmitting steel.

[0035] Working principle: First, the staff slides the connecting frame 201 into the slot 301 to install the hardness tester 2 on the front end of the connecting block 3. Due to the elastic force of the second spring 303 acting on the second limiting rod 302, the bottom of the second limiting rod 302 slides into the circular hole inside the connecting frame 201, so that the second limiting rod 302 limits the connecting frame 201, so that the hardness tester 2 is fixedly installed on the front end of the connecting block 3. Then, the rotating rod 106 is rotated to keep the first limiting rod 108 in a horizontal state to limit the stretching rod 102 so that it cannot move upward. By holding the handle 4, the detection rod 1 is extended. The hardness tester 2 is inserted into the interior of the post-cast strip, and then force is applied downward to make the bottom of the hardness tester 2 act on the horizontally placed force-transmitting steel for strength testing. When the vertically placed force-transmitting steel needs to be tested, the first limit rod 108 is rotated to vertical through the rotating rod 106, and then the stretching rod 102 is pulled by the pull rod 5. At this time, the first limit rod 108 passes through the second through groove 109, and the stretching rod 102 drives the connecting block 3 to rotate through the connecting rod 105, so that the hardness tester 2 is rotated to a horizontal state, and then the detection end of the hardness tester 2 can be applied to the surface of the vertically placed force-transmitting steel to perform a strength test on it.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
