Description

Technical Field

[0001] The utility model relates to the technical field of anchor cable anchoring, in particular to a mechanically pressure-regulated recyclable anchor cable structure. Background Art

[0002] Anchor cable reinforcement support is an important support method for building foundation pits. It is mostly used for foundation pit projects with high safety requirements or large-scale projects. Most of them are temporary supports. After the main structure is completed, these temporary support structures no longer play a role. Ordinary anchor cables cannot be recovered and are buried underground with the built structures, occupying a large amount of underground space, forming underground garbage, causing underground environmental pollution, and having a great impact on the excavation of adjacent plots. Recyclable anchor cables are the inevitable product of the development of anchor cable technology.

[0003] A recyclable anchor cable structure mentioned in the existing Chinese public patent (authorization announcement number: CN219862788U). It includes an anchor head, a plurality of anchor rods arranged in a matrix are arranged above the anchor head, the anchor rods are fixedly connected above by a fixing plate, the fixing plate is provided with four first through holes arranged in a matrix, the first through hole is provided with an anchor cable, a second through hole matching the first through hole is provided above the anchor head, the anchor cable passes through the second through hole below and is fixedly connected to a U-shaped plate, a connecting block is provided in the middle of the lower part of the U-shaped plate, mounting grooves are provided on both sides of the U-shaped plate, a shaft rod is provided in the mounting groove, the shaft rod is movably connected to a movable rod, and the movable rod is fixedly connected to the connecting block through a spring. This kind of anchor cable structure has a simple structure and is easy to operate. The anchor cable can be recovered by pulling the anchor cable, which effectively improves the convenience of anchor cable recovery.

[0004] In the process of installing the anchor cable of the existing recyclable anchor cable structure, the anchor cable needs to be inserted into the through hole on the anchor head, and then the end of the anchor head is limited by the connecting block arranged inside the through hole. However, this existing method of installing the anchor cable can only limit the anchor cable by driving the connecting block to limit the anchor cable by resetting the spring, and cannot adjust the bearing pressure of the anchor cable according to the soil layer where the anchor cable is located and the ultimate bearing capacity of the anchor cable design, thereby reducing the versatility of the device. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the pressure of the recyclable anchor cable structure cannot be adjusted according to the soil layer where the anchor cable is located. The present application provides a mechanically pressure-regulated recyclable anchor cable structure.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A mechanically pressure-regulated recyclable anchor cable structure comprises an anchor head, to which a cone head is fixedly connected, to which four circumferentially distributed anchor rods are fixedly connected, to which ends of the anchor rods are fixedly connected a fixing ring, to which a fixing plate is fixedly connected, to which four through holes are opened on the anchor head, in which anchor cables are slidably arranged, and an adjustment structure is arranged between the anchor head and the fixing plate.

[0008] By adopting the above technical solution, when the device needs to install an anchor cable, the end of the anchor cable is first inserted into the through hole, and the anchor cable is installed on the fixed plate through the adjusting structure, and its position is limited by the fixed plate. When the device is needed for support in the foundation pit, the limit between the anchor cable and the anchor head is adjusted through the adjusting structure, so that it can adapt to the ultimate bearing capacity of the soil layer and the anchor cable design in the corresponding foundation pit, so that the device can better meet the engineering needs when performing support work, and the versatility of the device in support work is improved. When the device completes the support and takes out the anchor cable, the adjustment structure facilitates the removal of the anchor cable, and improves the convenience of the device to recover the anchor cable.

[0009] Furthermore, the adjustment structure comprises a hose fixedly connected to the fixed plate, the anchor cable is slidably arranged inside the hose, and the hose is slidably arranged inside the through hole.

[0010] By adopting the above technical solution, the end of the hose is deformed so that the hose, which was originally loose between the hose and the anchor cable, can fit tightly on the anchor cable, and then the anchor cable can be adjusted according to different pressure requirements, reducing damage to the anchor cable during the adjustment process.

[0011] Furthermore, a rotating column is rotatably connected to the fixed disk, the rotating column is rotatably connected to the cone head, a main gear is fixedly connected to the end of the rotating column, the main gear is rotatably connected to the cone head, the main gear is meshed with a slave gear, the slave gear is fixedly connected to the end of the hose, and a gear ring is fixedly connected inside the anchor head, and the gear ring is meshed with the slave gear.

[0012] By adopting the above technical solution, the rotating plate drives the rotating column to rotate, so that the main gear rotates and drives the slave gear to rotate. At this time, the slave gear performs a circular motion along the gear ring as it rotates, thereby driving the end of the hose to perform a circular motion at the bottom of the through hole, causing the hose to deform inside the through hole and driving the anchor cable to move a certain amount, thereby limiting it inside the anchor head.

[0013] Furthermore, a sliding column is slidably connected inside the anchor head, and a clamping plate is fixedly connected to the end of the sliding column. The clamping plate is an arc-shaped plate, and the clamping plate is adapted to the hose.

[0014] By adopting the above technical solution, the clamping plate moves to both sides of the hose, thereby clamping both sides of the hose and limiting the anchor cable through the hose, thereby pre-fixing the anchor cable during the installation process.

[0015] Furthermore, a spring is sleeved on the sliding column, and two ends of the spring are fixedly connected to the clamping plate and the anchor head respectively.

[0016] By adopting the above technical solution, the clamping plate in the cone head is reset by the spring and moves along the sliding column to both sides of the hose, so that it can pre-fix anchor cables of different thicknesses.

[0017] Furthermore, a limiting column is fixedly connected inside the hose, a limiting plate is rotatably connected to the limiting column, and the limiting plate is adapted to the anchor cable.

[0018] By adopting the above technical solution, when the end of the anchor cable extends into the hose, it will resist the limit plate and continue to move inward, so that the limit plate rotates along the limit column, and its range of movement is limited by the limit plate.

[0019] Furthermore, a torsion spring is sleeved on the limiting column, and two ends of the torsion spring are respectively fixedly connected to the limiting plate and the hose.

[0020] By adopting the above technical solution, the limit plate is reset by the torsion spring, thereby limiting the shaking space of the anchor cable.

[0021] Furthermore, an arc-shaped groove is arranged inside the through hole, and the arc-shaped grooves are respectively on two sides of the through hole, and the two arc-shaped grooves and the through hole are in a Z shape.

[0022] By adopting the above technical solution, the arc groove and the through hole are in a Z shape, so that when the gear drives the hose to move in a circle, the hose also presents a Z shape, which better limits the anchor cable in the hose.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when the bearing pressure of the anchor cable needs to be adjusted, the rotating plate drives the rotating column to rotate, so that the main gear rotates and drives the slave gear to rotate. At this time, the slave gear performs a circular motion along the gear ring as it rotates, thereby driving the end of the hose to perform a circular motion at the bottom of the through hole, thereby deforming the end of the hose, so that the originally loose hose between the hose and the anchor cable fits tightly on the anchor cable, so that the anchor cable gradually becomes more and more tightly limited between the through hole on the anchor head as the rotating plate rotates, thereby adjusting the pressure of the anchor cable on the device, and also facilitating the setting of anchor cables of different thicknesses on the hose for supporting and installing, making the device more versatile.

[0025] 2. In the present application, when the anchor cable is installed on the device, the anchor cable is inserted into the hose, and the end of the anchor cable will resist the limit plate and continue to move inward, so that the limit plate rotates along the limit column, and then the limit plate is reset by the torsion spring to limit the swinging space of the anchor cable, and the clamping plate in the cone head is reset by the spring and moves along the sliding column to both sides of the hose, thereby clamping both sides of the hose and limiting the anchor cable through the hose, thereby pre-fixing the anchor cable during installation, reducing the misalignment of the anchor cable during adjustment and transportation of the device, and improving the stability of the device during use.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a mechanically pressure-regulated recoverable anchor cable structure.

[0035] Reference Figure 1 and Figure 2A mechanically pressure-regulated recyclable anchor cable structure comprises an anchor head 1, a cone head 2 is fixedly connected to the anchor head 1, four circumferentially distributed anchor rods 3 are fixedly connected to the anchor head 1, a fixing ring 4 is fixedly connected to the end of the anchor rod 3, a fixing plate 8 is fixedly connected to the fixing ring 4, four through holes 5 are opened on the anchor head 1, anchor cables 6 are slidably arranged in the through holes 5, and an adjustment structure is arranged between the anchor head 1 and the fixing plate 8.

[0036] When the device needs to install the anchor cable 6, the end of the anchor cable 6 is first inserted into the through hole 5, and the anchor cable 6 is installed on the fixed plate 8 through the adjustment structure, and its position is limited by the fixed plate 8. When the device is needed for support in the foundation pit, the limit between the anchor cable 6 and the anchor head 1 is adjusted through the adjustment structure, so that it can adapt to the ultimate bearing capacity of the soil layer and the anchor cable 6 designed in the corresponding foundation pit, so that the device can better meet the engineering needs when performing supporting work, and the versatility of the device in supporting work is improved. When the device completes the support and takes out the anchor cable 6, the adjustment structure facilitates the removal of the anchor cable 6, and improves the convenience of the device to recover the anchor cable 6.

[0037] Reference Figure 3 and Figure 4 , Figure 5 The adjustment structure includes a hose 7 fixedly connected to a fixed disk 8, an anchor cable 6 is slidably arranged inside the hose 7, and the hose 7 is slidably arranged inside the through hole 5. A rotating column 10 is rotatably connected to the fixed disk 8, a rotating plate 9 is fixedly connected to the rotating column 10, the rotating column 10 is rotatably connected to the cone head 2, a main gear 11 is fixedly connected to the end of the rotating column 10, the main gear 11 is rotatably connected to the cone head 2, the main gear 11 is meshed with a slave gear 16, the slave gear 16 is fixedly connected to the end of the hose 7, a gear ring 12 is fixedly connected inside the anchor head 1, and the gear ring 12 is meshed with the slave gear 16.

[0038] When the bearing pressure of the anchor cable 6 needs to be adjusted, the rotating plate 9 drives the rotating column 10 to rotate, so that the main gear 11 rotates and drives the slave gear 16 to rotate. At this time, the slave gear 16 performs a circular motion along the gear ring 12 as it rotates, thereby driving the end of the hose 7 to perform a circular motion at the bottom of the through hole 5, thereby deforming the end of the hose 7, so that the originally loose hose 7 between it and the anchor cable 6 fits tightly on the anchor cable 6, so that the anchor cable 6 gradually becomes more and more tightly limited between the through hole 5 on the anchor head 1 as the rotating plate 9 rotates. When the anchor cable 6 is taken out, the rotating plate 9 is rotated in the direction to loosen the hose 7, so that the anchor cable 6 can be taken out, thereby facilitating the device to adjust the pressure of the anchor cable 6, and also facilitating the setting of anchor cables 6 of different thicknesses on the hose 7 for supporting and installing, making the device more versatile.

[0039] Reference Figure 3A sliding column 14 is slidably connected in the anchor head 1, and a clamping plate 13 is fixedly connected to the end of the sliding column 14. The clamping plate 13 is an arc-shaped plate, and the clamping plate 13 is adapted to the hose 7. A spring 15 is sleeved on the sliding column 14, and the two ends of the spring 15 are respectively fixedly connected to the clamping plate 13 and the anchor head 1. A limiting column 18 is fixedly connected inside the hose 7, and a limiting plate 17 is rotatably connected to the limiting column 18, and the limiting plate 17 is adapted to the anchor cable 6. A torsion spring 19 is sleeved on the limiting column 18, and the two ends of the torsion spring 19 are respectively fixedly connected to the limiting plate 17 and the hose 7.

[0040] When the anchor cable 6 is installed on the device, the anchor cable 6 is inserted into the hose 7, and the end of the anchor cable 6 will resist the limit plate 17 and continue to move inward, so that the limit plate 17 rotates along the limit column 18, and then the limit plate 17 is reset by the torsion spring 19 to limit the swinging space of the anchor cable 6, and the clamping plate 13 in the cone head 2 is reset by the spring 15 and moves along the sliding column 14 to both sides of the hose 7, thereby clamping both sides of the hose 7 and limiting the anchor cable 6 through the hose 7, thereby pre-fixing the anchor cable 6 during the installation process, reducing the misalignment of the anchor cable 6 during the adjustment and transportation of the device, and improving the stability of the device during use.

[0041] Reference Figure 3 An arc groove 20 is arranged inside the through hole 5. The arc grooves 20 are respectively on both sides of the through hole 5. The two arc grooves 20 and the through hole 5 are in a Z shape.

[0042] The arc groove 20 and the through hole 5 are in a Z shape, so that when the gear 16 drives the hose 7 to move in a circle, the hose 7 also presents a Z shape, which better limits the anchor cable 6 in the hose 7.

[0043] Working principle: When the bearing pressure of the anchor cable 6 needs to be adjusted, the rotating plate 9 drives the rotating column 10 to rotate, so that the main gear 11 rotates and drives the slave gear 16 to rotate. At this time, the slave gear 16 performs a circular motion along the gear ring 12 as it rotates, thereby driving the end of the hose 7 to perform a circular motion at the bottom of the through hole 5, thereby deforming the end of the hose 7, so that the hose 7, which was originally loose between the anchor cable 6, fits tightly on the anchor cable 6, so that the anchor cable 6 gradually becomes more and more tightly limited with the through hole 5 on the anchor head 1 as the rotating plate 9 rotates, thereby adjusting the pressure of the anchor cable 6 on the device;

[0044] When the anchor cable 6 is installed on the device, the anchor cable 6 is inserted into the hose 7, and the end of the anchor cable 6 will resist the limit plate 17 and continue to move inward, so that the limit plate 17 rotates along the limit column 18, and then the limit plate 17 is reset by the torsion spring 19 to limit the swinging space of the anchor cable 6, and the clamping plate 13 in the cone head 2 is reset by the spring 15 and moves along the sliding column 14 to both sides of the hose 7, thereby clamping both sides of the hose 7 and limiting the anchor cable 6 through the hose 7, so that the anchor cable 6 is pre-fixed during the installation process, reducing the misalignment of the anchor cable 6 during the adjustment and transportation of the device.
