Description
Technical Field
[0001] The utility model relates to the technical field of anchor rod pulling devices, in particular to an anchor rod pulling device. Background Art
[0002] Anchor pulling device is hollow jack, which is often used in anchor pulling work. Hollow jack is also called hollow hydraulic jack or center hole jack. It is a special hydraulic lifting equipment, which is characterized by a central hollow design, that is, a large space is left in the middle of the lifting part of the jack. The main purpose of this design is to meet the lifting needs under special working conditions, such as lifting in the center of an object, passing through a fixed component or working in a confined space.
[0003] The existing anchor rod pulling device has some inconveniences when limiting and releasing the anchor rod. When limiting the anchor rod, due to its large center hole, the anchor rod will shake without additional fixing measures. Usually, the pin is hammered into the center hole of the hollow jack to achieve the fixing effect of the anchor rod. This method is more laborious and also makes it inconvenient to remove the pin when it is finally removed, and its applicability is poor. Utility Model Content
[0004] The utility model aims to provide an anchor rod pulling device, aiming to solve the problem that the anchor rod pulling device in the prior art has some inconveniences when limiting and releasing the anchor rod.

[0006] Preferably, the ring is coaxial with the axis of the hollow jack.
[0007] Preferably, the guide assembly includes a mounting plate, a guide plate and a limiting column, the mounting plate is arranged on the outer wall of the ring, the guide plate is arranged on the outer wall of the hollow jack, the limiting column is arranged at the bottom of the mounting plate, and the limiting column runs through the guide plate.
[0008] Preferably, the threaded hole is located directly below the guide hole.
[0009] Preferably, the inner side of the arc-shaped clamping plate is provided with an internal thread matching the outer surface of the anchor rod.
[0010] The beneficial effects of the utility model are:
[0011] When the utility model is in use, the end of the anchor rod is kept in the hollow of the circular ring, and the bolt is driven to rotate by turning the knob, and the rotation of the bolt drives the arc-shaped clamping plate to move. When the arc-shaped clamping plate moves, the guide column and the guide hole guide it, so that the arc-shaped clamping plate and the anchor rod are closely fitted, thereby achieving the purpose of fixing the anchor rod. When it is necessary to contact the fixing effect of the arc-shaped clamping plate on the anchor rod, the arc-shaped clamping plate can be moved away from the anchor rod by turning the knob in the opposite direction. The device has a simple structure, high practicality, and is suitable for market promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.
[0017] like Figures 1 to 3 As shown, an anchor rod pulling device includes a hollow jack 1, a circular ring 2 is arranged on the top of the hollow jack 1 through a guide assembly, guide holes 9 are penetrated on both sides of the circular ring 2, guide columns 8 are penetrated inside the guide holes 9, arc-shaped clamping plates 6 are symmetrically arranged inside the circular ring 2, and the guide columns 8 are connected to the arc-shaped clamping plates 6, threaded holes 10 are penetrated on both sides of the circular ring 2, bolts 11 are threadedly connected inside the threaded holes 10, a limiting hole 7 is arranged on the back side of the arc-shaped clamping plate 6, and one end of the bolt 11 is rotatably connected to the limiting hole 7, and a knob 12 is arranged on the other end of the bolt 11.
[0018] In this embodiment, when the anchor rod needs to be fixed, the end of the anchor rod is kept in the hollow part of the ring 2, and the knob 12 is turned to drive the bolt 11 to rotate. The rotation of the bolt 11 drives the arc clamp 6 to move. When the arc clamp 6 moves, the guide column 8 and the guide hole 9 guide it, so that the arc clamp 6 and the anchor rod are tightly fitted to achieve the purpose of fixing the anchor rod. When it is necessary to contact the arc clamp 6 to fix the anchor rod, the arc clamp 6 can be moved away from the anchor rod by screwing the knob 12 in the opposite direction. The device has a simple structure, high practicality, and is suitable for market promotion.
[0019] Specifically, the ring 2 is coaxial with the axis of the hollow jack 1 .
[0020] like Figure 2 As shown, the guide assembly includes a mounting plate 3, a guide plate 4 and a limiting column 5. The mounting plate 3 is arranged on the outer wall of the circular ring 2, the guide plate 4 is arranged on the outer wall of the hollow jack 1, the limiting column 5 is arranged at the bottom of the mounting plate 3, and the limiting column 5 passes through the guide plate 4. When the mounting plate 3, the guide plate 4 and the limiting column 5 cooperate with each other, the circular ring 2 is arranged above the hollow jack 1.
[0021] Specifically, the threaded hole 10 is located directly below the guide hole 9 .
[0022] like Figure 1 As shown, the inner side of the arc-shaped clamping plate 6 is provided with an internal thread 13 matching the outer surface of the anchor rod. The provision of the internal thread 13 strengthens the fixing effect of the arc-shaped clamping plate 6 on the anchor rod.
[0023] Working principle: During use, when the anchor rod needs to be fixed, the end of the anchor rod is kept in the hollow part of the ring 2, and the knob 12 is turned to drive the bolt 11 to rotate. The rotation of the bolt 11 drives the arc-shaped clamping plate 6 to move. When the arc-shaped clamping plate 6 moves, the guide column 8 and the guide hole 9 guide it, so that the arc-shaped clamping plate 6 and the anchor rod are closely fitted to achieve the purpose of fixing the anchor rod. When it is necessary to contact the arc-shaped clamping plate 6 to fix the anchor rod, the arc-shaped clamping plate 6 can be moved away from the anchor rod by screwing the knob 12 in the opposite direction. The device has a simple structure, high practicality, and is suitable for market promotion.
