In addition, if the detailed description of the known technology is unnecessary for showing the features of the present invention, it will be omitted.

[0027] Please refer to Figures 1 to 3 , Figure 1 a multi-purpose bolt hanger 1 provided by the present invention (hereinafter referred to as "bolt hanger 1"), Figure 2 is Figure 1 a view of the bolt hanger in the A-A direction in Figure 3 is Figure 1 a view of the bolt hanger in the B-B direction in. Among them, the A-A direction can be understood as the rear view, and correspondingly, the B-B direction can be understood as the front view. Of course, when Figure 1 is understood as the front view, the A-A direction can be understood as the perspective of the left view, and correspondingly, the B-B direction can be understood as the perspective of the right view.

[0028] A bolt hanger 1 provided in this embodiment includes a support frame, a fastener disposed inside the support frame, and an ear plate 111 disposed on the support frame for easy lifting. The fastener fixes the bolt 2 when the bolt 2 penetrates into the support frame. The support frame includes lateral support plates 112 located on the upper and lower and left and right opposite sides of the support frame, a front end plate 113 located at the front end of the support frame, and a sealing end plate 114 located at the rear end of the support frame. The sealing end plate 114 is used to tightly press the fastener. Please refer to Figure 2 , the sealing end plate 114 is provided with a first bolt hole 114-1 for the bolt 2 to pass through (in Figure 3 ).

[0029] Please continue to refer to Figure 1, in this embodiment, the fastener includes a fastening nut 121 and a locking nut 122. The fastening nut 121 and the locking nut 122 are sleeved on the anchor rod 2 in ( Figure 3 ), the fastening nut 121 and the locking nut 122 are arranged axially, and the locking nut 122 is located between the fastening nut 121 and the front end plate 113. In this embodiment, in order to facilitate the lifting ear plate 111, a lifting hole 111-1 is provided on the ear plate 111, and a steel cable can pass through the lifting hole 111-1 to facilitate lifting the anchor rod hanger 1 with the anchor rod 2. The fastening nut 121 and the locking nut 122 can also be used for subsequent tensioning of the anchor rod 2.

[0030] Please continue to refer to Figure 2 and Figure 3 , in this embodiment, the lateral support plates 112 on the upper and lower opposite sides and the left and right opposite sides of the support frame are also provided with hollow areas 115, and the hollow areas 115 expose the fasteners (including the fastening nut 121 and the locking nut 122), which is convenient for the fasteners to lock the anchor rod 2 inside the support frame. Setting the hollow area 115 can reduce the self-weight of the anchor rod hanger 1. In addition, since the fastener penetrates deep into the support frame, the hollow area is provided to expose other components such as the fastener located inside the support frame, which is convenient for the rotation in and out of the fastener and other components, and is convenient for the anchor rod 2 to be locked.

[0031] Please refer to Figure 1 , the hollow area 115 is also provided at the rear end of the lateral support plate 112, and the hollow area 115 is also used to expose the preset position of the end plate 114, and can also indicate the installation position of the end plate 114. Specifically in this embodiment, the hollow area 115 is provided on both sides at the rear end of the lateral support plate 112. The end plate 114 can be pushed from the rear end to the front end direction of the hollow area 115, and the end plate 114 can be installed at the designated position.

[0032] Please continue to refer to Figure 1 and Figure 2 , the end plate 114 is connected to the rear end of the support frame through a fixing structure - a pin 13. The fixing structure uses a pin 13, and fixing holes 14 matching the pin 13 are provided on the lateral support plate 112 and the end plate 114. In other possible embodiments, the fixing structure can also adopt at least one connection or fixing method or component such as a welding structure, a screw, and a key, and the fixing hole 14 can be matched with fixing structures such as screws. The pin 13 is driven behind the end plate 114 to fix the end plate 114. The pin 13 can prevent the end plate 114 from accidentally falling off and ensure the locking of the fastening nut 121 and the locking nut 122. In other possible embodiments, when the thickness of the end plate 114 is sufficient to accommodate the pin 13, the pin 13 can be driven into the inside of the end plate 114. In addition to using the pin 13, components such as screws can also be used as the fixing structure accordingly.

[0033] In this embodiment, the pin 13 can be driven into the lateral support plates 112 from the upper and lower sides, or into the lateral support plates 112 on the left and right sides. Correspondingly, fixing holes 14 can be reserved at the corresponding positions of the pin 13.

[0034] Please continue to refer to Figures 1 to 3 , the lateral support plates 112 on the left and right sides extend towards the bottom, that is, at the bottom of the anchor rod hanger 1, in the direction away from the ear plates 111. The bottom support plates 116 extend from the lateral support plates 112 on the left and right sides to the bottom of the support frame. The height of the part of the bottom support plate 116 that extends beyond the lateral support plates 112 at the bottom is greater than or equal to the length of the fixing structures such as the pin 13 that extend beyond the support frame. When the anchor rod hanger 1 is placed, the design that the bottom support plates 116 on the left and right sides extend beyond the lateral support plates 112 allows the bottom support plates 116 to directly contact the placement surface, avoiding the fixing structures such as the pin 13 from directly contacting the placement surface and causing wear of the pin 13. In some embodiments, the lateral support plates 112 on the left and right sides can be appropriately extended beyond the lower lateral support plates 112, and the extension length is greater than the length after the pin 13 is screwed in. In addition, during the manufacturing process, the lateral support plates 112 on the left and right sides and the bottom support plates 116 can be integrally formed and cut. In Figure 1 and Figure 2 the design, the lateral support plates 112 and the bottom support plates 116 are integrally formed.

[0035] Please refer to Figure 3 , the front end plate 113 is provided with a second anchor rod hole 113-1 for the anchor rod 2 to pass through. The first anchor rod hole 114-1 and the second anchor rod hole 113-1 are coaxially arranged, and their centers are on the same axis. The diameter of the second anchor rod hole 113-1 is smaller than the diameter of the fastener, that is, the diameter of the check nut 122. The diameter of the second anchor rod hole 113-1 is larger than the diameter of the anchor rod 2, and the anchor rod 2 can extend out of the second anchor rod hole 113-1, facilitating the subsequent tensioning of the anchor rod 2. In this embodiment, the diameter of the second anchor rod hole 113-1 can be larger than that of the first anchor rod hole 114-1 to facilitate the subsequent tensioning of the anchor rod 2.

[0036] Please refer to Figure 1, the ear plate 111 is integrally connected to the lateral support plates 112 on the left and right sides. In terms of manufacturing process, after directly welding and assembling the anchor rod hanger 1, the ear plate 111 and the lifting hole 111-1 on the ear plate 111 can be directly cut out. In other possible embodiments, the ear plate 111 can also be movably connected to the lateral support plates 112 on the left and right sides. Such a design enables the ear plate 111 to adaptively change its angle along with the angle of the sling during the lifting process, reducing the wear probability between the sling and the ear plate 111 and extending the service life of the components.

[0037] In this embodiment, the anchor rod hanger 1 can be assembled through the following exemplary assembly process. First, the vertically opposed lateral support plates 112 and the horizontally opposed lateral support plates 112 can be welded to form a basic shape. Subsequently, the front end plate 113 is welded to the front end of the lateral support plate 112. Among them, the hollow area 115 can be cut at this time or pre-cut and formed on the original lateral support plate 112.

[0038] After the basic shape is formed, the anchor rod 2 can be installed at the position of the front end plate 113, and the fastening nut 121 and the anti-loosening nut 122 are assembled. The anti-loosening nut 122 locks the anchor rod 2 towards the front end plate 113, and the fastening nut 121 further locks the anti-loosening nut 122 and the anchor rod 2 towards the front end plate 113. During the locking process, the hollow area 115 can be utilized to achieve the locking of the fastening nut 121 and the anti-loosening nut 122.

[0039] The end sealing plate 114 has been pre-sleeved on the anchor rod 2. Relying on the design of the hollow area 115, the end sealing plate 114 further presses tightly the fastening nut 121 and the anti-loosening nut 122 to prevent the fastening nut 121 and the anti-loosening nut 122 from loosening. After the end sealing plate 114 is pressed to the designated position, the pin 13 is inserted from the fixing hole 14 inside the end sealing plate 114 to fix the end sealing plate 114 at the preset position. After the pin 13 is driven in, the fastening nut 121 and the anti-loosening nut 122 can be further tightened. Of course, the end sealing plate 114 can also be fixed at the rear side of the end sealing plate 114 through pins and screws, and the end sealing plate 114 is thereby fixed to the lateral support plate 112.

[0040] In some embodiments, the end sealing plate 114 can also be connected to the lateral support plate 112 through the empty slots and card slots provided on the lateral support plate 112. Additionally, the lateral support plate 112 can be designed as a ring shape, with internal threads provided on the lateral support plate 112. The end sealing plate 114 can be screwed in behind the fastening nut 121 and the anti-loosening nut 122 by means of the threads and press tightly the fastening nut 121 and the anti-loosening nut 122.

[0041] After the anchor rod hanger 1 is installed at both ends of the anchor rod 2, the anchor rod 2 can be integrally lifted to the designated position by lifting the anchor rod hanger 1 with a crane. After the anchor rod 2 is lifted to the designated position, the step-by-step tensioning of the anchor rod 2 can be achieved by means of the compression fastening nut 121 and the anti-return nut 122 in the anchor rod hanger 1. In other possible embodiments, the pin 13 and the fixing hole 14 correspondingly limit the position of the end sealing plate 114, and the step-by-step limitation of the end sealing plate 114 can assist in the step-by-step tensioning of the anchor rod 2.

[0042] In other possible embodiments, an anchor rod hanger 1 provided in this embodiment can be used as an anchor rod hanger unit. By assembling multiple anchor rod hanger units, multiple anchor rods 2 can be lifted at one time. The ear plates 111 can be arranged on the top or the lateral support plates 112 on the four peripheral edges, which is convenient for the crane to lift. The assembly between multiple anchor rod hanger units can be achieved by bolt connection. After multiple anchor rod hanger units together with the anchor rod 2 are lifted to the preset position, multiple anchor rod hanger units can be disassembled, and then the anchor rod hanger units are respectively transported to the positions where the anchor rods 2 need to be installed.

[0043] The present invention provides an anchor rod hanger 1, which can provide components convenient for lifting the anchor rod 2 through the ear plates 111 and fasteners on the support frame. The anchor rod hanger 1 also has a hollowed-out area 115. In addition to reducing the self-weight of the anchor rod hanger 1, the hollowed-out area 115 can also expose the positions of the fastening nut 121 and the anti-return nut 122, which is convenient for locking the exposed fastening nut 121 and anti-return nut 122. The anchor rod hanger 1 also has a fixing structure, such as a pin 13 and a fixing hole 14, which can fix the end sealing plate 114, and further compress the fastening nut 121 and the anti-return nut 122, and finally lock the anchor rod 2 in a fixed position. The lateral support plates 112 on the left and right sides of the anchor rod hanger 1 exceed the lateral support plates 112 at the bottom, and the exceeding part can prevent fasteners, such as pins 13, from directly contacting the contact surface of the anchor rod hanger 1 and prevent the fasteners from being damaged. A second anchor rod hole 113-1 is opened on the front end plate 113 of the anchor rod hanger 1, which can be further used for tensioning the anchor rod 2. The anchor rod hanger 1 of the present invention can not only lift the anchor rod 2, but also, after the anchor rod 2 is lifted to the preset position, has the function of continuously tensioning the anchor rod 2.

[0044] Although some exemplary embodiments of the present invention have been shown above, those skilled in the art will understand that changes can be made to these exemplary embodiments without departing from the principle or spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
