In addition, it should be understood that when the terms "comprise" and / or "include" are used in this description, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 3 As shown, a pouring head wire rope clamping device according to an embodiment of the present invention comprises a frame 1 and a centering load-bearing clamp 2 having a conical sleeve, wherein the frame 1 is connected to the centering load-bearing clamp 2, and the conical sleeve is used to be sleeved on the pouring head wire rope to be clamped, so as to utilize the conical structure of the conical sleeve to clamp the pouring head of the pouring head wire rope to be clamped.

[0032] Among them, the cone angle of the cone structure of the cone sleeve can be set according to actual conditions, the centering load-bearing clamp 2 is fixedly connected to the frame 1 by threaded fixing or by a detachable connecting part available on the market, and the structure of the centering load-bearing clamp 2 can also be set according to actual conditions, which will not be elaborated here.

[0033] Through the conical structure of the conical outer sleeve of the centering load-bearing clamp 2, different specifications of the casting head wire rope to be clamped can be firmly clamped, which has wide applicability and good fastening effect, so as to facilitate dynamic and static tests of the casting head wire rope, and is simple to operate and low in cost.

[0034] Preferably, in the above technical solution, it also includes an auxiliary clamp block 6 adapted to the conical structure of the conical sleeve, the auxiliary clamp block 6 is detachably arranged in the conical structure of the conical sleeve, and the conical auxiliary clamp block 6 is used to be sleeved on the steel wire rope of the casting head to be clamped, so as to utilize the conical structure of the conical auxiliary clamp block 6 to clamp the casting head of the casting head wire rope to be clamped.

[0035] Among them, the cone angle of the conical structure of the auxiliary clamp 6 can be set according to actual conditions. Preferably, the cone angle of the conical outer shell is set to 40°, and the cone angle of the inner conical structure of the auxiliary clamp 6 is set to 18°. The outer surface of the auxiliary clamp 6 is fitted with the conical structure of the auxiliary clamp 6; wherein the auxiliary clamp 6 can be formed in one piece.

[0036] Preferably, in the above technical solution, the frame 1 is a cubic structure composed of connecting rods 5 and steel plates 12, and any steel plate 12 is provided with an opening for passing the steel wire rope of the pouring head to be clamped.

[0037] The frame 1 may be a four-column structure composed of connecting rods 5 and steel plates 12. The four columns of the four-column structure are four connecting rods 5. That is, four connecting rods 5 are connected between two oppositely arranged steel plates 12, and the two ends of any connecting rod 5 are fixedly connected to the two oppositely arranged steel plates 12 by threaded connection or welding.

[0038] Preferably, the above technical solution further comprises a disassembly auxiliary device 4 , which passes through the opening and is connected to the auxiliary clamp 6 .

[0039] Among them, the unloading auxiliary device can be connected to the auxiliary clamp block 6 by means of a tenon bite, or connected to the auxiliary clamp block 6 by means of a hinge, so that the disassembly auxiliary device 4 can accurately separate the auxiliary clamp block 6 from the inner cone structure of the conical outer sleeve. At the same time, due to the different angles of the inside and outside of the auxiliary clamp block 6, when the outer surface of the auxiliary clamp block 6 is in contact with the conical outer sleeve, the inner surface is inclined at 18°, which ensures the axial tension of the steel wire rope of the pouring head to be clamped, and the outer surface is 40°, which is the same as the angle of the inner cone structure of the conical outer sleeve, ensuring that the disassembly auxiliary device 4 can accurately separate the auxiliary clamp block 6 from the inner cone structure of the conical outer sleeve. By disassembling the auxiliary device 4, it is convenient to quickly and flexibly realize the clamping and disassembly of the steel wire rope of the pouring head to be clamped, and the operation is simple.

[0040] Preferably, in the above technical solution, the conical auxiliary clamp block 6 includes a first clamp block 14 and a second clamp block 10, the first clamp block 14 and the second clamp block 10 are detachably connected, and the disassembly auxiliary device 4 is connected to the first clamp block 14, so that it is easier to disassemble the casting head wire rope to be clamped;

[0041] The disassembly of the wire rope of the pouring head to be clamped requires a disassembly auxiliary device 4, and the disassembly auxiliary device 4 may be, but is not limited to, a metal rod adapted to the opening.

[0042] Preferably, in the above technical solution, a clamp block two-dimensional lifting module 3 is further included, which is provided with an elevator 8, and the clamp block two-dimensional lifting module 3 is connected to the frame 1, and the elevator 8 is connected to the second clamp block 10. That is, by lifting and lowering the elevator 8, the second clamp block 10 is controlled to approach or separate from the first clamp block 14, which makes it easier to clamp and disassemble the pouring head wire rope to be clamped, and the operation is simple.

[0043] The clamp block two-dimensional lifting module 3 further includes a rolling wheel 7 , and the rolling wheel 7 is movably connected to the connecting rod 5 of the frame 1 .

[0044] The clamp block two-dimensional lifting module 3 translates in three directions of freedom to accurately determine the installation position of the steel wire rope of the pouring head to be clamped, thereby ensuring the stability and safety of the steel wire rope of the pouring head to be clamped during installation.

[0045] Moreover, the elevator 8 is equipped with two guide columns 9, which are relatively arranged on both sides of the elevator 8. The elevator 8 and the guide columns 9 are fixed together through a flat plate 13. A second clamping block 10 is connected above the elevator 8, and a first clamping block 14 is carried above the second clamping block 10. A stabilizing structure 11 is also arranged at the front and rear of the elevator 8. The stabilizing structure 11 is specifically a cross bar or other structure that carries the second clamping block 10. When the elevator 8 is maintained to move in the lifting direction by the guide columns 9, the second clamping block 10 will not deflect. By setting the stabilizing structure 11, when the second clamping block 10 and the first clamping block 14 are fixed to obtain the auxiliary clamping block 6, they will not move forward and backward.

[0046] refer to Figure 1 and Figure 2 , the rolling wheel 7 rolls along the connecting rod 5, the elevator 8 moves vertically at the bottom of the clamp block two-dimensional lifting module 3, and the rolling wheel 7 drives the clamp block two-dimensional lifting module 3 to move horizontally along the connecting rod 5. The elevator 8 is manually displaced in the lifting direction, and is also lifted and lowered under electric power. At the same time, with the help of the tension applied to the steel wire rope of the pouring head to be clamped, it automatically moves in the tensile direction of the tension. Through the cooperation of the rolling wheel 7 and the connecting rod 5, the sliding of the rolling wheel 7 is conveniently realized, thereby driving the clamp block two-dimensional lifting module 3 to move, realizing the installation and positioning of the steel wire rope of the pouring head to be clamped, and fixing the auxiliary clamp block 6 at the same time.

[0047] Compared with the prior art, the clamping device for dynamic and static testing of steel wire ropes according to the present invention has the following advantages:

[0049] 2) The centering load-bearing fixture 2 composed of the conical outer sleeve and the auxiliary clamp block 6 can be loaded and disassembled, so that the test device can perform both dynamic and static tests;

[0050] 3) The clamp block two-dimensional lifting module 3 can translate in three degrees of freedom to accurately complete the installation and positioning of the wire rope sample, and at the same time has the function of clamp block fixing to ensure the stability and safety of the clamp block and the sample during installation;

[0051] 4) The test device adopts electric or manual adjustment of the displacement of the clamp block two-dimensional lifting module 3 in the lifting direction, and at the same time uses the tensile force of the main machine to make the clamp block automatically move into position in the tensile direction, which is convenient to operate, easy to control, and saves manpower.

[0052] The test device of the present invention is used to clamp the steel wire rope sample, and the centering load-bearing fixture 2 composed of the conical outer sleeve and the auxiliary clamp block 6 and the disassembly auxiliary device 4 are used to perform fast and flexible loading and disassembly, that is, to perform dynamic tests and static tests. Compared with the traditional test method of clamping the steel wire rope sample directly by the clamp, the clamping method of the present invention for dynamic and static tests of the steel wire rope for mechanical property testing is convenient for disassembly of the sample by adding a sample clamp block between the clamp and the sample, so the method of the present invention has a wide range of applications, a short test time, and makes installation, static testing, dynamic testing and disassembly of damaged samples easier to perform.
