Description
Technical Field
[0001] This utility model relates to the technical field of anchor cable tensioning tools, and in particular to an anchor cable tensioning tool that is easy to clamp. Background Technology
[0002] Anchor cable tensioning devices are devices that inject hydraulic oil into their internal parts, using the hydraulic pressure to raise the central cylinder of the device, thereby providing tension to the device. Existing cable tensioning devices generally have a hollowed-out handle with grooves at the top and bottom to allow hydraulic oil to enter and flow out, thus increasing and decreasing the pressure of the device. However, due to the very heavy weight of the device itself, the hollowed-out handle is prone to bending or breakage, resulting in unstable hydraulic capacity. Furthermore, the interlocking between the anchor plate and the anchor cable during the raising of the central cylinder can cause the anchor cable to easily disengage. Therefore, the above problems need to be corrected. Utility Model Content

The connecting block is hollow inside, and two connection ports are opened on the bottom surface of the connecting block to facilitate the entry and exit of hydraulic oil; a fixed valve 3 is installed at the connection port, and a handle is installed on the upper end of the connecting block, with the other end of the handle fixed to the outer cylinder 1; an internal thread groove is opened on the bottom surface of the outer cylinder 1, and a base plate 2 is threadedly connected to the bottom surface of the outer cylinder 1. A middle cylinder 5 is provided on the upper end of the base plate 2. Thread grooves are opened on the outer sides of the upper and lower ends of the middle cylinder 5. A sealing ring 9 is threadedly connected to the lower end of the middle cylinder 5, and the outer side of the sealing ring 9 abuts against the inner wall of the outer cylinder 1 to facilitate sealing the space between the outer cylinder 1 and the middle cylinder 5; and an inner cylinder 7 is sleeved on the lower end of the middle cylinder 5, and an anchor cup 6 is sleeved on the upper end of the inner cylinder 7 to facilitate fixing the anchor cup 6.
[0020] In this utility model, the inner cylinder 7 is provided inside the middle cylinder 5. The lower end of the inner cylinder 7 has a through ring to facilitate the sealing of the space and abuts against the top surface of the base plate 2. An anchor cup 6 is provided at the upper end of the inner cylinder 7, and an inner nut 8 is provided at the upper end of the base plate 2. The inner nut 8 is threadedly connected to the lower end of the inner cylinder 7. A baffle is fixed to the outer side of the upper end of the inner cylinder 7 and abuts against the inner wall of the middle cylinder 5. An installation groove is opened in the middle of the top surface of the inner cylinder 7, and a first spring 10 is installed in the installation groove. A mushroom head 11 is fixed to the upper end of the first spring 10. Multiple anchor cups are opened on the inner wall of the anchor cup 6. The equidistant triangular grooves facilitate the movement of the anchor plate 14 inside and outside the grooves; the anchor plate 14 is installed in the grooves, with the upper end of the anchor plate 14 abutting against the upper end of the triangular grooves and the lower end of the anchor plate 14 abutting against the mushroom head 11; the upper end of the middle cylinder 5 is threadedly connected to the top pressure device 4, the top pressure device 4 has a groove inside, and a second spring 12 is installed in the groove. The lower end of the second spring 12 is installed with a retraction ring 13, and the bottom of the retraction ring 13 abuts against the anchor cup 6. The top pressure device 4, the inner cylinder 7 and the bottom plate 2 are provided with a guide hole through the middle to facilitate the entry of the steel cable.
[0021] Working principle: When using this utility model, first lift the device so that the anchor cable enters the anchor cup 6 through the hole in the middle of the top pressure device 4. At this time, start the device so that hydraulic oil enters from the fixed valve 3. Since the space where the hydraulic oil enters is closed, as the hydraulic oil enters, it begins to squeeze the inner cylinder 7, causing the inner cylinder 7 to rise, pushing the first spring 10, and then pushing the mushroom head 11 to rise. At this time, since the anchor plate 14 is installed in the groove on the inner side of the anchor cup 6 and is attached to the mushroom head 11, the lower end of the anchor plate 14 will shift outward, and the upper end of the anchor plate 14 will shift inward. At this time, due to the action of the second spring 12 and the anchor retraction ring 13, the anchor cup 6 will be fixed and will not shift upward, thus clamping the anchor cable and fixing the inner cylinder 7. At this time, as the hydraulic oil continues to enter, it will push the middle cylinder 5 to move upward, thus causing the top pressure device 4 to move upward, thus generating tension force between the middle cylinder 5 and the inner cylinder 7, thus tensioning the anchor cable. After the tensioning is completed, the hydraulic oil is discharged from the fixed valve 3, and then the device is taken out.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
