[0002] The sky anchor device is a device used to hoist and install large-tonnage equipment in hydropower stations or water conservancy projects. It is widely used in water conservancy and hydropower projects. Especially when the space of a truck crane or other hoisting equipment is insufficient to install the equipment to the designated position, the sky anchor device can effectively avoid the problem of insufficient hoisting space.

[0003] Therefore, the performance of the sky anchor device directly affects the reliability and working efficiency of hoisting and installing equipment. During the use of the current sky anchor device, the fixation of the anchor rod and the ceiling installation hole is carried out by using a grouting pipe for concrete fixation. Since the installation hole at the top is usually perpendicular to the ground, during the process of inserting the anchor rod into the installation hole for grouting, external fixation of the anchor rod is required, which increases the connection steps and reduces the fixation efficiency of the anchor rod.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6 , the present invention provides a technical solution: a limited-space hoisting sky anchor device, including an anchor plate 1, a reinforcing plate 2, a connection hole 3, an anchor rod 4, a wedge block 5, a connector 6, an upper pulley 7, a lower pulley 8, a steel wire rope 9, and a winch 10.

[0031] The anchor plate 1 is a rectangular steel plate structure. The surface of the anchor plate 1 is penetrated by a reinforcing plate 2. The reinforcing plate 2 is an octagonal structure, and the thickness of the reinforcing plate 2 is greater than that of the anchor plate 1. The surfaces of the anchor plate 1 and the reinforcing plate 2 are penetrated by circular connection holes 3. A connection structure is arranged on the surface of the anchor plate 1. The connection structure arranges a bolt 4 to be welded to the anchor plate 1 to connect the anchor plate 1 to the ceiling. The connection structure includes the bolt 4. The bolt 4 is a long rod-shaped structure with a threaded structure on its outer surface. One end of the bolt 4 is provided with a long strip-shaped wedge slot. A wedge block 5 is clamped in the wedge slot of the bolt 4. The cross-section of the wedge block 5 is a triangular structure, and the width of the wedge block 5 is equal to the diameter of the bolt 4. The other end of the bolt 4 is welded to the surface of the anchor plate 1. An arc-shaped weld bead is arranged on the surface of the anchor plate 1 in contact with the bolt 4. Two weld beads are respectively arranged on the two side surfaces of the anchor plate 1, and the weld beads on the two side surfaces of the anchor plate 1 are arranged in a staggered manner;

[0032] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, when using this device, the anchor plate 1, the reinforcing plate 2 and the connection hole 3 are all prefabricated in the factory. Use a three-boom rock drill to drill an installation hole in the ceiling. Insert the wedge slot end of the bolt 4 and the wedge block 5 together into the installation hole, and continuously hammer the bolt 4, so that the bolt 4 drives the wedge block 5 to move into the installation hole. Under the reaction force of the bottom surface of the installation hole, the wedge block 5 moves into the wedge slot at one end of the bolt 4, so that the wedge slot at the anchoring end of the bolt 4 opens to both sides and tightly fits with the inner wall of the installation hole, so that the bolt 4 is fixed in the installation hole. Use a grouting machine to grout into the installation hole to complete the installation of the bolt 4. Similarly, fix the remaining bolts 4. After the age reaches 100%, conduct a pull-out test on each bolt 4. Each bolt 4 should withstand a tensile force of 7.5t to meet the requirements. After the pull-out test meets the requirements, weld the anchor plate 1. Make the arc-shaped weld bead on the surface of the anchor plate 1 contact the bolt 4, and use a multi-arm drill basket or a support vehicle to cooperate to weld the anchor plate 1 and the bolt 4.

[0033] A hoisting structure is arranged below the anchor plate 1. The hoisting structure arranges an upper pulley 7 and a lower pulley 8 to realize a two-fold pulley block to increase the load capacity of the device. The hoisting structure includes a connecting piece 6. The cross-section of the connecting piece 6 is a closed U-shaped structure, and the connecting piece 6 is sleeved on the inner wall of the connection hole 3 on the surface of the anchor plate 1. The lower part of the connecting piece 6 is connected with an upper pulley 7. The upper pulley 7 is a fixed pulley structure. A lower pulley 8 is arranged below the upper pulley 7. The lower pulley 8 is a movable pulley structure. A steel wire rope 9 is arranged on the groove surface of the upper pulley 7. One end of the steel wire rope 9 bypasses the lower pulley 8 below and is fixed to the lower end of the upper pulley 7. The other end of the steel wire rope 9 is fixed to the rotating shaft of a winch 10. The structure connected to the surface of the anchor plate 1 and the anchor plate 1 constitutes a set of hoisting mechanisms, and 2 sets of hoisting mechanisms are symmetrically arranged;

[0034] As Figure 1 ,Figure 5 and Figure 6 As shown in Figure 6 , after the anchor plate 1 is welded, the upper pulley 7 is fixed to the anchor plate 1 by the connecting member 6, and the wire rope 9 is passed through the upper pulley 7. One end of the wire rope 9 is fixed to the lower end of the upper pulley 7 after passing around the lower pulley 8, and the other end is fixed to the rotating shaft of the hoist 10, so that the upper pulley 7 and the lower pulley 8 form a pulley block structure to increase the load capacity of the device. Two sets of lifting mechanisms composed of the anchor plate 1 and the pulley block are symmetrically arranged and are respectively connected to two hoists 10. During the subsequent lifting process, the lower pulley 8 is connected to the object to be lifted, and the hoist 10 and the wire rope 9 can be used to perform the lifting process.

[0035] Working principle: When using the sky anchor device for hoisting in a confined space, the wedge slot end of the anchor rod 4 and the wedge block 5 are jointly inserted into the installation hole. The wedge block 5 is used to drive the wedge slot at the anchoring end of the anchor rod 4 to open to both sides, so that the anchor rod 4 is tightly attached to the inner wall of the installation hole. After the installation of the anchor rod 4 is completed, the anchor plate 1 and the anchor rod 4 are welded, and the pulley block composed of the upper pulley 7 and the lower pulley 8 is connected to the anchor plate 1. The pulley block composed of the upper pulley 7 and the lower pulley 8 can increase the load capacity of the device. The lower pulley 8 is connected to the object to be lifted, and the hoist 10 is started. The hoist 10 drives the wire rope 9 to move, and the lifting process of the device can be carried out, which increases the overall practicability.
