Technical Field

[0001] This utility model belongs to the field of steel strand cutting technology, and in particular relates to a steel strand cutting device after a static load anchoring test. Background Technology

[0002] In static load anchorage tests of steel strands, after the anchorage is installed, a predetermined load needs to be applied using testing equipment to determine the anchorage performance under the predetermined load, thereby judging the reliability of the anchorage. After the test, it is often necessary to cut the bundled steel strands from the middle of the equipment. However, traditional cutting methods have many shortcomings, such as the steel strands easily scattering and causing injury during the cutting process, complex operation and low efficiency, and a lack of effective safety protection measures.

[0003] To address the above issues, we designed a steel strand cutting device after a static load anchoring test. Utility Model Content

[0004] The purpose of this utility model is to provide a steel strand cutting device after a static load anchoring test. By designing a clamping sleeve and a semi-circular groove to securely clamp the steel strand and prevent it from spreading out, combined with a hydraulically driven rapid cutting method, it solves the problems of easy spreading and injury, complicated operation and low efficiency in the existing steel strand cutting process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a steel strand cutting device after a static load anchoring test, comprising a hydraulic cylinder, a manual hydraulic pump, a shearing head, a steel strand mounting and shearing guide frame, and a wire clamping sleeve; the manual hydraulic pump is connected to the hydraulic cylinder via two high-pressure oil pipes; the hydraulic cylinder has an insertion hole at its telescopic end; the shearing head is inserted and installed in the insertion hole; the steel strand mounting and shearing guide frame includes a circular groove that mates with the bottom of the hydraulic cylinder; two arc plates are axially symmetrically fixed at the upper end of the circular groove; the upper ends of the two arc plates are connected by two connecting... The connecting horizontal plates are integrated; an inverted L-shaped end seat is fixed on each of the two connecting horizontal plates; one end of the shearing head contacts the vertical surface of the L-shaped end seat; a semi-circular groove that mates with the steel strand is opened on the inner wall of the horizontal part of the L-shaped end seat; a V-shaped groove that is perpendicular to the semi-circular groove is opened at the center of the horizontal part of the L-shaped end seat, and the end of the shearing head mates with the V-shaped groove; semi-circular groove bodies that are coaxially arranged with the semi-circular groove are symmetrically installed on both sides of the L-shaped end seat; the wire clamping sleeve is sleeved on the semi-circular groove body.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:

[0026] Please see Figure 1-5As shown, after the static load anchorage test of the steel strand is completed, in order to cut the steel strand safely and effectively, this utility model provides a steel strand cutting device after the static load anchorage test, including a hydraulic cylinder 1, a manual hydraulic pump 2, a shearing head 3, a steel strand mounting shearing guide frame 4, and a clamping sleeve 5. The manual hydraulic pump 2 is connected to the hydraulic cylinder 1 through two high-pressure oil pipes 6. The telescopic end of the hydraulic cylinder 1 has an insertion hole. The shearing head 3 is inserted and installed in the insertion hole. The steel strand mounting shearing guide frame 4 includes a circular groove 41 that mates with the bottom of the hydraulic cylinder 1. Two arc plates 42 are fixed symmetrically at the upper end of the circular groove 41. The upper ends of the two arc plates 42 are connected as one piece by two connecting horizontal plates 43. An inverted L-shaped end seat 44 is fixed on the two connecting horizontal plates 43. One end of the shearing head 3 contacts the vertical surface of the L-shaped end seat 44. The horizontal inner wall of the L-shaped end seat 44 has a semi-circular groove 45 that mates with the steel strand. The horizontal part of the L-shaped end seat 44 has a V-shaped groove 46 that is perpendicular to the semi-circular channel 45, and the end of the shear head 3 mates with the V-shaped groove 46. Semi-circular groove bodies 47, which are coaxially arranged with the semi-circular channel 45, are symmetrically installed on both sides of the L-shaped end seat 44. The wire clamping sleeve 5 is fitted onto the semi-circular groove body 47.

[0027] One of the arc plates 42 has a handle 48 fixed to its outer wall, which facilitates the movement of the steel strand and its attachment to the shearing guide frame 4.

[0028] The shearing head 3 includes a plug 31 that mates with a socket. A trapezoidal block 32 is fixed to the end of the plug 31. A cutting blade 33 is integrally formed on the top of the trapezoidal block 32. When the cutting blade 33 of the shearing head 3 comes into contact with the steel strand, it applies sufficient shearing force to cut the steel strand.

[0029] The clamping sleeve 5 includes a circular tube 51 fitted outside the semi-circular groove 47. The side wall of the circular tube 51 has a V-shaped through groove 52 arranged axially, and the width of the V-shaped through groove 52 is greater than the diameter of the steel strand. At least two shank bolts 53 are threaded through the circular tube 51, and the shank bolts 53 point towards the center of the V-shaped through groove 52, thereby clamping the steel strand and preventing it from slipping or spreading during cutting.

[0030] To prevent the V-shaped through groove 52 of the clamp sleeve 5 from flipping downwards, a semi-circular tube plug 54 is fixed at one end of the round tube 51, which mates with the inner wall of the horizontal part of the L-shaped end seat 44. The semi-circular tube plug 54 is positioned relative to the V-shaped through groove 52.

[0031] When using Figure 1In the shown configuration, first, hang the shearing guide frame 4 on the steel strand, and fasten the semi-circular channel 45 and two semi-circular grooves 47 onto the steel strand. Then, take the clamping sleeve 5, first pass the steel strand through the V-shaped through groove 52, and then put the clamping sleeve 5 on the semi-circular groove 47. The V-shaped through groove 52 is completely covered upwards by the semi-circular groove 47. Tighten the bolts 53 on both sides to clamp the steel strand. Manually press the manual hydraulic pump 2 to drive the piston end of the hydraulic cylinder 1 to extend and push the shearing head 3 towards the L-shaped end seat 44 to cut the steel strand. After cutting, the clamping sleeve 5 and the semi-circular grooves 47 protect the broken steel strand, preventing it from breaking apart and injuring people. After cutting, release the handle of the manual hydraulic pump 2, switch the oil circuit, and retract the piston end of the hydraulic cylinder 1. Because the clamping sleeve 5 and the semi-circular grooves 47 protect the broken steel strand, they prevent the steel strand from breaking apart and injuring people after cutting. Loosen the bolt 53 with handle, remove the wire clamp sleeve 5, and remove the shearing guide frame 4 from the steel strand.
