Description

Technical Field

[0001] The utility model relates to the technical field of anchor cables, in particular to a limiting device for processing anchor cables. Background Technique

[0002] An anchor cable is a prestressed member used in civil engineering, usually composed of high-strength steel strands or steel bars. They are fixed in stable rock masses or soil layers through anchor heads to improve the stability of structures such as slopes, tunnels, and bridges. Anchor cables can resist tensile forces. By applying prestress, stability can be provided before the structure is subjected to external forces, or used to control further movement when the structure has already deformed.

[0003] During the processing of anchor cables, heat treatment is required to improve the strength of the anchor cables. Quenching is a metal heat treatment process that involves heating the steel to a suitable temperature above, usually above the critical point Ac3 of hypoeutectoid steel or the critical point Ac1 of hypereutectoid steel, holding for a period of time to achieve austenitization, and then rapidly cooling, usually in water, oil, or other cooling media. The purpose of quenching is to improve the hardness, strength, and wear resistance of the metal, and at the same time, it can also improve the physical and chemical properties of some special steels.

[0004] During quenching, the anchor cable needs to be quickly placed in the oil for cooling. However, the commonly used method in the prior art is to fix one end of the anchor cable and use lifting equipment to put the anchor cable in. In this way, when the length of the anchor cable is large, a sufficiently large site is required to completely lift the anchor cable, which is inconvenient. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a limiting device for processing anchor cables is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a limiting device for processing anchor cables, including an electric telescopic rod and a connecting frame:

[0008] The upper end of the connecting frame is connected to the machine frame through several connecting rods, and the outer wall of the connecting frame is movably connected with an installation frame through a hinge;

[0009] A guiding hole is axially and penetratingly opened in the middle of the connecting frame, and the bottom of the electric telescopic rod penetrates through the guiding hole and extends below the connecting frame;

[0010] A hook is installed at the bottom of the installation frame;

[0011] A plurality of support components are installed on the outside of the electric telescopic rod, and each group of support components cooperates with the installation frame.

[0012] Preferably, the support assembly includes rollers and a baffle. The baffle is inclined and installed at the lower end outside the electric telescopic rod, and the rollers are rotatably arranged on the upper part of the baffle.

[0013] Preferably, a guide rail is provided on one side of the mounting frame close to the baffle. The rollers are rollingly arranged inside the guide rail, and the size of the rollers matches the size of the guide rail.

[0014] Preferably, a plurality of the baffles and the mounting frames are distributed in a circular array, and the positions of the baffles match the positions of the mounting frames.

[0015] Preferably, the hook is arranged in an upwardly curved state.

[0016] Preferably, a plurality of the hooks are all at the same horizontal height, and the cable anchor to be quenched is placed between the plurality of hooks.

[0017] A cable anchor limiting device for cable anchor processing proposed by the present utility model has the beneficial effects that: in this cable anchor processing limiting device, the cable anchor is placed in a coiled manner in the hooks distributed in a circular array. For a relatively long cable anchor, the cable anchor can be coiled several times in the hooks. In this way, not only can the problem of the cable anchor falling off during the cooling process be prevented, but also since it is placed in the hooks in a coiled manner, the requirement for the processing workshop to be large enough is solved.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Embodiment 1

[0026] Referring to Figures 1-5 , a limiting device for cable anchor processing includes an electric telescopic rod 2 and a connecting frame 4:

[0027] The upper end of the connecting frame 4 is connected to the machine frame through several connecting rods 1, and the outer wall of the connecting frame 4 is movably connected with a mounting frame 6 through a hinge 5;

[0028] A guiding hole 3 is axially penetrated through the middle of the connecting frame 4, and the bottom of the electric telescopic rod 2 penetrates through the guiding hole 3 and extends below the connecting frame 4;

[0029] A hook 10 is installed at the bottom of the mounting frame 6; the hook 10 is arranged in an upwardly curved state, and multiple hooks 10 are all at the same horizontal height, and the cable anchors to be quenched are placed between the multiple hooks 10.

[0030] Multiple groups of support components are installed on the outer side of the electric telescopic rod 2, and each group of support components cooperates with the mounting frame 6.

[0031] After the cable anchor is heated, its shape can change arbitrarily. Under the traction of the equipment, it is coiled between the inner sides of multiple hooks 10. After coiling multiple circles until all the cable anchors are placed inside the hooks 10. Since the hooks 10 are bent upward and the shape of the heated cable anchor can be changed, it can be very stably fixed in the hooks 10. Use a lifting device to move the machine frame fixing the electric telescopic rod 2 and the connecting frame 4 above the cooling pool and lower the height so that the cable anchor is completely immersed in the oil for cooling to complete the quenching process.

[0032] Embodiment 2

[0033] Refer to Figures 1-5 , the difference between this embodiment and Embodiment 1 is that the support component includes a roller 8 and a baffle 9. The baffle 9 is inclined and installed at the lower outer end of the electric telescopic rod 2, and the roller 8 is rotatably arranged on the upper part of the baffle 9. When the length of the cable anchor is relatively large, the operator controls the electric telescopic rod 2 to rise. At this time, the angle between the baffle 9 and the connecting frame 4 gradually becomes larger. Compared with the initial position, the distance between the hook 10 and the connecting frame 4 increases at this time. As a result, the annular diameter formed by the multiple hooks 10 arranged in an annular array also increases accordingly. In this way, when placing a cable anchor with a larger length, the length of one coil of the coiled cable anchor will be larger than before, and the coiling and limiting of a cable anchor with a larger length can be completed in fewer turns.

[0034] On one side of the mounting bracket 6 close to the baffle 9, a guide rail 7 is provided. The roller 8 is rotatably arranged inside the guide rail 7, and the size of the roller 8 matches the size of the guide rail 7. Both the baffle 9 and the mounting bracket 6 are distributed in an annular array, and the position of the baffle 9 matches the position of the mounting bracket 6. The cooperation between the roller 8 and the guide rail 7 ensures that the trajectory of the mounting bracket 6 does not deviate during angle adjustment.

[0035] The working principle of this device is as follows:

[0036] When the length of the anchor cable is relatively large, the operator controls the electric telescopic rod 2 to rise. At this time, the angle between the baffle 9 and the connecting frame 4 gradually increases. Compared with the initial position, the distance between the hook 10 and the connecting frame 4 increases at this time. As a result, the annular diameter formed by the multiple hooks 10 distributed in an annular array also increases accordingly. In this way, when placing an anchor cable with a larger length, the length of one coil of the coiled anchor cable will be larger than before, and the coiling and limiting of the anchor cable with a larger length can be completed in fewer turns.

[0037] After the anchor cable is heated, its shape can be changed arbitrarily. Under the traction of the device, it is coiled between the inner sides of multiple hooks 10. After coiling multiple turns until all the anchor cables are placed inside the hooks 10. Since the hooks 10 bend upward and the shape of the heated anchor cable can be changed, it can be very stably fixed inside the hooks 10. Then, use the lifting device to move the frame that fixes the electric telescopic rod 2 and the connecting frame 4 above the cooling pool and lower the height so that the anchor cable is completely immersed in the oil for cooling, completing the quenching process.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
