Description

Technical Field

[0001] This utility model relates to the technical field of beverage production equipment, specifically to an assembled anchor cable tensioning device. Background Technology

[0002] Anchor cables are steel strands that are divided into many strands and anchored into anchorages when securing the main cable in the side openings of a suspension bridge. Anchor cables are prestressed steel strands that pass through the slope's sliding surface, with one end fixed to the slope surface and the other end anchored in stable rock mass within the sliding surface. They directly generate anti-sliding resistance on the sliding surface, increasing anti-sliding frictional resistance and keeping the structural surface under compression. This improves the integrity of the slope rock mass, fundamentally improving its mechanical properties, effectively controlling displacement, and promoting stability, thus achieving the purpose of controlling bedding planes, landslides, and unstable rocks.

[0003] A search revealed that Chinese Patent CN218971225U discloses a positioning structure and a mining anchor cable tensioning mechanism, comprising: a pneumatic hydraulic pump, a fixing block and a support plate on the back of the pneumatic hydraulic pump, a traction rope at the bottom of the fixing block, a baffle on the back of the pneumatic hydraulic pump, a connecting rod on the side of the baffle, a positioning plate sleeved on the surface of the connecting rod, and a positioning groove on the surface of the positioning plate. When using this patent, after the anchor cable tensioning equipment is used and needs to be moved, the hook is first removed from the pull ring, then the positioning plate is lowered, and the tensioning jack is placed on the positioning plate. Then, only one hand is needed to lift the pneumatic hydraulic pump for easy and convenient transport. This avoids the inconvenience of using a conventional anchor cable tensioning equipment where one hand needs to hold the tensioning jack and the other hand the pneumatic hydraulic pump, and the lack of a positioning device for the tensioning jack makes it difficult to move.

[0004] Based on the search and existing technology, it was found that the existing technology uses jacks to tension the anchor cable, but the above-mentioned patents do not have a locking structure at the lifting end of the jack. A search revealed that Chinese patent CN221321818U discloses an anchor cable tensioner, in which the lifting end of the jack is equipped with a locking structure, but the locking structure is too complicated and the maintenance is cumbersome.

[0025] 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 protection scope of the present utility model.

[0026] Please see Figures 1-8In this embodiment of the utility model, the assembled anchor cable tensioning device includes a hollow jack 1 and a locking structure 3. The hollow jack 1 has handles 2 fixed on both sides of the cylinder body. The hollow jack 1 has a hydraulic system that provides hydraulic drive on its outer side. The locking structure 3 includes a sleeve 4. The sleeve 4 is slidably sleeved on the lifting end of the hollow jack 1. The sleeve 4 has multiple inner conical holes 7 on its circular surface. Each inner conical hole 7 has a conical sleeve inside it. The conical sleeve is divided into multiple locking petals 5 of equal size. The sleeve 4 has an adjustment structure on its outer side that applies downward pressure to each locking petal 5.

[0027] As can be seen from the above connection relationship, each anchor cable passes through each inner conical hole 7, and then the locking petal 5 in each inner conical hole 7 contacts the anchor cable. At this time, downward pressure is applied to the locking petal 5 to make the locking petal 5 contact the anchor cable. When the hollow jack 1 pushes the entire sleeve 4 outward, the sleeve 4 tends to push outward relative to the anchor cable. At this time, the anchor cable causes the locking petal 5 to move towards the small diameter end of the inner conical sleeve through friction, so that the locking petal 5 presses the anchor cable, and the anchor cable is pulled by the sleeve 4. It can be seen that the locking structure 3 has a simple overall structure, no tight parts, is easy to manufacture, and is easy to operate, reducing installation time and improving work efficiency.

[0028] Specifically, the hydraulic system includes a controller, a hydraulic pump 15, a directional valve 16, and an oil tank 14. The pumping end of the hydraulic pump 15 and the return end of the directional valve 16 are both connected to the oil tank 14. The outlet end of the hydraulic pump 15 is connected to the inlet end of the directional valve 16. The two output ends of the directional valve 16 are respectively connected to the two oil ends of the hollow jack. The hydraulic pump 15 and the directional valve 16 are both electrically connected to the controller.

[0029] The hydraulic system described above is provided for reference only. It can be replaced with other hydraulic systems, and no limitation is made here.

[0030] Specifically, multiple annular grooves are formed on the inner side of the cone sleeve, and the multiple annular grooves form a friction groove 12. The friction groove 12 is designed to increase the friction inside the cone sleeve.

[0031] Specifically, the adjustment structure includes an adjusting bolt 6 and a pressure plate 9. The pressure plate 9 is circular in shape and is coaxially arranged with the sleeve 4. An internal threaded hole is provided at the center of the circular surface of the pressure plate 9. The outer side of the adjusting bolt 6 is threaded into the internal threaded hole. One end of the adjusting bolt 6 is rotatably installed on the sleeve 4. A first guide groove 13 with a T-shaped cross-section is provided on the outer side of the locking flap 5. A first guide bar 8 adapted to it is slidably arranged in the groove of the first guide groove 13. The first guide bar 8 is fixed in the inner conical hole 7. A second guide groove 11 with a T-shaped cross-section is provided at the top of the locking flap 5. A second guide bar 10 adapted to it is slidably arranged in the groove of the second guide groove 11. The second guide bar 10 is fixed on the pressure plate 9.

[0032] As can be seen from the above connection relationship: rotating the adjusting bolt 6 causes the pressure plate 9 to move towards the sleeve 4 through the outer side of the adjusting bolt 6 via thread transmission. The pressure plate 9 applies pressure to the locking petal 5, and the locking petal 5 moves along the first guide bar 8 towards the inner conical hole 7. At this time, each locking petal 5 in each inner conical hole 7 approaches each other, squeezing the anchor cable and increasing the friction between the inner side of the conical sleeve and the anchor cable.

[0033] Specifically, multiple through holes are opened on the circular surface of the pressure plate 9. The multiple through holes are aligned one-to-one with multiple inner conical holes 7, and the diameter of the through holes is larger than the inner diameter of the inner conical sleeve. The anchor cable passes through the through holes, so the through holes are designed to facilitate the anchor cable to pass through.

[0034] Working principle:

[0035] The first step is to pass each anchor cable through each inner conical hole 7;

[0036] The second step is to rotate the adjusting bolt 6. The outer side of the adjusting bolt 6 moves the pressure plate 9 toward the sleeve 4 through the threaded transmission. The pressure plate 9 applies pressure to the locking petal 5. The locking petal 5 moves along the first guide bar 8 toward the inner cone hole 7. At this time, each locking petal 5 in each inner cone hole 7 approaches each other and squeezes the anchor cable, increasing the friction between the inner side of the cone sleeve and the anchor cable.

[0037] The third step is that when the hollow jack 1 pushes the entire sleeve 4 outward, the sleeve 4 tends to push outward relative to the anchor cable. At this time, the anchor cable causes the locking disc 5 to move towards the small diameter end of the inner cone sleeve through friction, so that the locking disc 5 presses the anchor cable and the anchor cable is pulled by the sleeve 4.

[0038] In summary, the locking structure 3 has a simple overall structure with no tightly fitted parts, making it easy to manufacture and operate, reducing installation time and improving work efficiency.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
