In these projects, the tension control of geotechnical anchor cable is crucial. If the anchor cable tension is too large, it may cause local damage to the geotechnical body; if the tension is too small, it cannot achieve the expected reinforcement effect. Therefore, in order to ensure that the geotechnical anchor cable can work stably and effectively, accurate tension adjustment technology is needed, and the geotechnical anchor cable tension regulator emerges as the times require.

[0005] The purpose of this invention is to address the shortcomings of existing technologies where anchor cables are directly installed within the constraint structure. During actual construction, the tension of the anchor cables needs to be adjusted according to construction requirements. When workers need to adjust the tension of the anchor cables, they need to use additional equipment. When using the equipment, it is also necessary to move the equipment to the site. Due to the harsh construction environment, it is not conducive to the movement of the equipment, which leads to a longer operation cycle and increased difficulty in the adjustment operation. Therefore, this invention proposes a geotechnical anchor cable tension adjuster.

A knob is fixedly connected to the center of the double-ended screw. A limit block is fixedly connected to the upper surface of the anchor cable fixing device.

[0007] Preferably, the number of positioning sleeves matches the anchor cable body. Through the connection between the positioning sleeves and the connecting plate, the anchor cable body can be connected while the connecting plate is under force, and tension can be applied to the anchor cable body to ensure that the tension of the anchor cable body is adjusted.

[0008] Preferably, both ends of the connecting arm are arc-shaped, and there are two connecting arms. The two connecting arms are symmetrically arranged about the anchor cable fixing device. The position of the connecting plate can be changed through the connecting arms, and then the connecting plate is subjected to force to ensure that the connecting plate can apply tension to the anchor cable body.

[0009] Preferably, the positioning block contacts the outer arc surface of the anchor cable fixing device. There are two positioning blocks, which are arranged symmetrically about the anchor cable fixing device. The position of the shaft can be precisely positioned by the positioning blocks to ensure the stability of the connecting arm in the linkage state.

[0010] Preferably, the mounting bracket is fixedly connected to the lower surface of the anchor cable fixing device. The mounting bracket is L-shaped and there are two mounting brackets.

[0014] 1. In this utility model, by setting an adjustment component, when the tension of the anchor cable body needs to be adjusted outward, the operator holds the knob with one hand and rotates it clockwise, driving the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw engages with the tooth groove inside the threaded sleeve, thereby driving the threaded sleeve to move towards the limiting block. The movement of the threaded sleeve causes the mounting plate and the linkage block to move synchronously. The linkage block moves towards the positioning block, and at the same time, the movement of the linkage block cooperates with the assembly frame, thereby driving the connecting arm to move, causing the angle of the connecting arm to change. While the angle of the connecting arm changes, it pushes the connecting plate upward. The connecting plate and the positioning sleeve cooperate to adjust the tension of the anchor cable. After the adjustment is completed, the operator can release the hand holding the knob and stop rotating, thus fixing the tension of the anchor cable. By setting an adjustment component, the tension of the anchor cable can be effectively adjusted. When the equipment needs to be used, the tension of the anchor cable in the equipment can be adjusted without the aid of other equipment, thereby reducing the situation of extending the operation cycle due to adjustment operations and further improving the convenience of using the equipment.

The adjusting component 4 is sleeved on the outer arc surface of the anchor cable body.

[0023] In this embodiment: the adjusting component 4 includes a positioning sleeve 41, the inner wall of which is fixedly connected to the anchor cable body.

A shaft 46 is fixedly connected to the side of the positioning block 45 away from the anchor cable fixing device 2. A mounting bracket 47 is fixedly connected to the end of the shaft 46 away from the positioning block 45. A linkage block 48 is slidably connected to the outer arc surface of the shaft 46. An assembly frame 49 is fixedly connected to the upper surface of the linkage block 48. A rotating hole is opened on the surface of the assembly frame 49. A connecting arm 44 is rotatably connected to the inner wall of the rotating hole of the assembly frame 49. An installation plate 410 is fixedly connected to one side of the linkage block 48. A threaded sleeve 411 is fixedly connected to the side of the installation plate 410 near the positioning block 45. A two-way screw 412 is threadedly connected to the inner wall of the threaded sleeve 411. A knob 413 is fixedly connected to the center of the two-way screw 412. A limit block 414 is fixedly connected to the upper surface of the anchor cable fixing device 2.

[0024] Specifically, the number of positioning sleeves 41 matches the number of anchor cable bodies.

[0025] The effect achieved by the above components is that, through the connection between the positioning sleeve 41 and the connecting plate 42, the anchor cable body can be connected while the connecting plate 42 is under force, and tension can be applied to the anchor cable body to ensure that the tension of the anchor cable body is adjusted.

[0026] Specifically, both ends of the connecting arm 44 are arc-shaped, and there are two connecting arms 44. The two connecting arms 44 are arranged symmetrically about the anchor cable fixing device 2.

[0027] The effect achieved by the above components is that the position of the connecting plate 42 can be changed through the connecting arm 44, and then the connecting plate 42 is subjected to force to ensure that the connecting plate 42 can apply tension to the anchor cable body.

[0028] Specifically, the positioning block 45 contacts the outer arc surface of the anchor cable fixing device 2. There are two positioning blocks 45, which are arranged symmetrically about the anchor cable fixing device 2.

[0029] The effect achieved by the above components is that the position of the shaft 46 can be precisely positioned by the positioning block 45 to ensure the stability of the connecting arm 44 in the linkage state.

[0030] Specifically, the mounting bracket 47 is fixedly connected to the lower surface of the anchor cable fixing device 2. The mounting bracket 47 is L-shaped and there are two mounting brackets 47. The two mounting brackets 47 are arranged symmetrically about the anchor cable fixing device 2.

[0031] The effect achieved by the above components is that the other end of the shaft 46 can be supported by the mounting bracket 47, and the position of the linkage block 48 can be constrained.

[0032] Specifically, the toothed groove inside the threaded sleeve 411 meshes with the bidirectional lead screw 412. When the threaded sleeve 411 is under full tension, it contacts the side surface of the limiting block 414. There are two threaded sleeves 411, which are arranged symmetrically about the bidirectional lead screw 412.

[0033] The effect achieved by the above components is that, through the threaded sleeve 411, when the operator turns the knob 413, the threaded screw drives the threaded sleeve 411 to unfold to both ends, so as to ensure that the position of the mounting plate 410 can be moved.

[0034] Specifically, the surface of the limiting block 414 is provided with a through hole, the limiting block 414 passes through the bidirectional lead screw 412, the limiting block 414 contacts the side surface of the knob 413, there are two limiting blocks 414, and the two limiting blocks 414 are arranged symmetrically about the knob 413.

[0035] The effect achieved by the above components is that the position of the knob 413 can be restricted by the limiting block 414, so as to prevent the knob 413 from shifting when the bidirectional lead screw 412 and the threaded sleeve 411 are engaged, thus ensuring that the knob 413 is always in the center position.

[0036] Working principle: When the tension of the anchor cable body needs to be adjusted outward, the operator holds the knob 413 with one hand and rotates it clockwise, which drives the double-acting screw 412 to rotate. The rotation of the double-acting screw 412 engages with the toothed groove inside the threaded sleeve 411, thereby driving the threaded sleeve 411 to move towards the limiting block 414. The movement of the threaded sleeve 411 causes the mounting plate 410 and the linkage block 48 to move synchronously. The linkage block 48 moves towards the positioning block 45. At the same time, the movement of the linkage block 48 cooperates with the assembly frame 49, thereby driving the connecting arm 44 to move, so that the connecting arm 44... As the angle changes, the connecting arm 44 pushes the connecting plate 42 upward while changing its angle. The connecting plate 42 and the positioning sleeve 41 work together to adjust the tension of the anchor cable. Once the adjustment is complete, the operator can release the knob 413 and stop rotating, thus fixing the tension of the anchor cable. By setting the adjustment component 4, the tension of the anchor cable can be effectively adjusted. When the equipment needs to be used, the tension of the anchor cable inside the equipment can be adjusted without the aid of other equipment, thereby reducing the extension of the operation cycle due to adjustment operations and further improving the convenience of using the equipment.
