Description

Technical Field

[0001] The utility model relates to the technical field of mechanical accessories, in particular to a special tool for storing and accommodating anchor nuts. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The anchor bolts of power transmission lines are divided into two parts: screws and nuts. After the foundation of the tower is poured, the anchor nuts need to be recycled. They can only be used again when the foundation strength reaches the standard and the tower can be assembled. Therefore, the anchor nuts are stored separately for a certain period of time. Since there are many types of anchor bolts for the tower foundation of a single overhead line project, ranging from M24 to M100, it is easy to have the problem of confusing the storage of nuts of different specifications during the nut recycling process. When the staff use them again, it is very easy to confuse the use and use large nuts instead of small ones in an irregular way. Once the nuts are used incorrectly, it is easy to cause the connection between the anchor nuts and the tower to be loose, and may even cause safety accidents such as the overturning of the tower. Utility Model Content

[0004] The utility model aims to provide a storage box for anchor nuts, comprising a box body, a box cover and a column; the box body and the box cover are connected by a hinge, and a column for supporting nuts is welded at the bottom of the box body.

[0005] As a further technical solution, the box body, box cover and columns are all made of stainless steel.

[0006] As a further technical solution, a plurality of hollow grooves are provided on the surface of the box body.

[0007] As a further technical solution, a rubber pad is provided inside the box cover.

[0008] As a further technical solution, a lock is provided between the box body and the box cover.

[0009] As a further technical solution, the surface of the box cover is also provided with specification identification information of the anchor nuts to be stored.

[0010] As a further technical solution, handles are provided on both sides of the box body.

[0011] As a further technical solution, the diameter of the column is smaller than the inner diameter specification size of the anchor nut to be accommodated, and larger than the inner diameter size of a nut that is one specification smaller than the anchor nut to be accommodated.

[0012] As a further technical solution, the spacing between the columns is larger than the opposite side dimension of the anchor nut to be received, and smaller than half of the sum of the opposite side dimension of the anchor nut to be received and the opposite side dimension of a nut one size larger than the anchor nut to be received.

[0013] As a further technical solution, the height of the column is less than the thickness of the two anchor nuts to be received. Beneficial effects of one or more of the above technical solutions:

[0014] Adjust the diameter of the column according to the specifications of the nuts to be collected, ensuring that the nuts to be collected can easily pass through the columns, while nuts smaller than the specifications of the nuts to be collected cannot be inserted into the columns. By setting the spacing between the columns, ensure that adjacent columns can be inserted into the nuts to be collected. Nuts larger than the specifications of the nuts to be collected can be inserted individually, but cannot be inserted into two adjacent columns at the same time. The problem of chaotic storage of nuts of different specifications during nut recycling is effectively solved. During the secondary use, the nut specification identification information on the surface of the box cover can be used to quickly confirm the nut model, effectively avoiding the problem of replacing small with large during use. Set the column to a smooth stainless steel material to facilitate the storage and use of anchor nuts. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The drawings in the specification, which constitute a part of the present application, are used to provide a further understanding of the present application. The illustrative embodiments of the present application and their descriptions are used to explain the present application and do not constitute a limitation on the present application.

[0016] Figure 1 It is a structural schematic diagram of the utility model.

[0017] In the figure, 1 is the box cover; 2 is the box body; 3 is the column; 4 is the hinge; 5 is the rubber pad; 6 is the lock; 7 is the hollow groove; 8 is the handle. DETAILED DESCRIPTION

[0018] The following is combined with Figure 1 , describing the specific implementation of this embodiment.

[0019] Combination Figure 1 The embodiment of the present application provides a storage box for anchor nuts, including a box body 2, a box cover 1, and a column 3; the box body 2 and the box cover 1 are both made of stainless steel, which has high strength and can effectively bear the weight of the anchor nuts. The box body 2 and the box cover 1 are connected by a hinge 4, and a lock 6 is also provided between the box body 2 and the box cover 1. The fixed part of the lock 6 is installed on the box cover 1, and the movable part of the lock 6 is installed on the box body 2 corresponding to the fixed part of the lock 6. The lock 6 can be used to fix the box body 2 and the box cover 1 to reduce shaking.

[0020] Furthermore, the box cover 1 is provided with specification identification information of the anchor nut, which can be highlighted by fixing a specification identification information nameplate on the box cover 1 or by directly engraving the identification information on the surface of the box cover 1, which is not specifically limited here. A rubber pad 5 is also provided inside the box cover 1, and the position of the rubber pad 5 corresponds to the position of the column 3. The rubber pad 5 can reduce the impact of the anchor nut on the box cover 1 during transportation.

[0021] Furthermore, the surface of the box body 2 is hollowed out, and a plurality of hollow grooves 7 are opened on the surface of the box body 2, which can effectively reduce the weight of the box body 2 without destroying the storage function of the box body 2. Handles 8 are also provided on both sides of the box body 2, so that the staff can move the anchor nut storage box by grasping the handles 8, which is convenient for the workers to extract and move.

[0022] Furthermore, a plurality of columns 3 are welded to the bottom of the box body 2. The column 3 is also made of stainless steel and is a cylindrical structure with a smooth surface. The purpose of quickly storing and taking out the anchor nuts can be achieved. In this embodiment, the number of columns 3 is set to four. Those skilled in the art can also set the number of columns 3 to other numbers as needed to increase the number of anchor nut storage boxes. For example, the number of columns 3 can be designed to be six, eight, etc., and the size of the box body 2 and the box cover 1 only needs to be adjusted accordingly. No specific limitation is made here.

[0023] In this embodiment, the diameter of the column 3 is strictly calculated to ensure that the anchor nuts of the same specification can be inserted into the column 3, and nuts smaller than this specification cannot be inserted. At the same time, the distance between the columns 3 is also strictly calculated to ensure that the anchor nuts of the same specification can be inserted into the column 3, and nuts larger than this specification can be inserted individually, but cannot be inserted into two adjacent columns 3 at the same time. Based on the power industry standard "Anchor Bolts and Nuts for Transmission Towers" (DL / T1236-2013), the inner diameter of the anchor nut is represented by the symbol da, and the inner diameter of the anchor nut includes the upper limit value and the lower limit value of the inner diameter size; the opposite side size of the anchor nut is represented by the symbol s, and the opposite side size of the anchor nut is also divided into the upper limit value and the lower limit value of the opposite side size; the diameter of the column 3 in the box body 2 is d1; the distance between adjacent columns 3 (measured with the center of the column as the distance) is d2; the height of the column is h.

[0024] As for the diameter of the column 3, in this embodiment, the diameter of the column 3 is slightly smaller than the inner diameter specification size of the nut to be stored, and larger than the inner diameter size of the nut that is one specification smaller than the nut to be stored. As shown in Table 1, taking the M30 anchor nut as the reference, when the specification of the anchor nut is less than or equal to M30, at this time, the diameter d1 of the column 3 in the anchor nut storage box is the upper limit da of the inner diameter size of the anchor nut to be stored minus 1mm; when the specification of the anchor nut is greater than M30, the diameter d1 of the column 3 in the anchor nut storage box is the lower limit da of the inner diameter size of the anchor nut to be stored minus 2mm. For example, the upper limit of the inner diameter size of the M30 anchor nut is 32.4mm, at this time, the diameter of the column 3 in the M30 anchor nut storage box is 31.4mm; the lower limit of the inner diameter size of the M36 anchor nut is 36mm, at this time, the diameter of the column 3 in the M36 anchor nut storage box is 34mm.

[0025] The purpose of the above setting is that when the specification of the anchor nut is less than or equal to M30, for example, the M30 anchor nut and the M27 anchor nut, the upper limit of the inner diameter size of the M27 anchor nut is close to the lower limit of the inner diameter size of the M30 anchor nut. At this time, if 1mm is subtracted from the lower limit of the inner diameter size of the M30 anchor nut, the M27 anchor nut will still pass through the column 3 in the M30 anchor nut storage box; when the specification of the anchor nut is greater than M30, although subtracting 2mm from the upper limit of the inner diameter size of the anchor nut can ensure that the low-specification nut cannot pass through the column 3, it will cause the diameter of the column 3 to become larger, increasing the production cost.

[0026]

[0027] Table 1 Anchor nut inner diameter dimensions (unit: mm)

[0028] Regarding the spacing between the columns 3, in the present embodiment, the spacing between the columns 3 is larger than the opposite side dimension of the nut to be received, and smaller than one-half of the sum of the opposite side dimension of the nut to be received and the opposite side dimension of a nut one size larger than the nut to be received. Similarly, taking the M36 nut as an example, the horizontal spacing between the columns 3 should satisfy that two M36 nuts can be placed at the same time, but one M36 nut, one M42 nut or even two M42 nuts cannot be placed at the same time. The upper limit of the opposite side dimension of the M36 nut is 55mm, and the lower limit of the opposite side dimension is 53.8mm. The minimum opposite side dimension of the M42 nut is 63.1mm, that is, the spacing between adjacent screws should be greater than 55mm and less than (53.8+63.1) / 2mm. At the same time, considering the internal tooth depth of the nut and the actual manufacturing factors, it can be designed to be 57mm.

[0029] Furthermore, in this embodiment, the height h of the column 3 is slightly smaller than the thickness of two anchor nuts to be received. Specifically, the height of the column 3 can be set to 1.6-1.8 times the height of a single anchor nut to be received. Through the above setting, during use, the staff can easily and quickly access the anchor nuts.

[0030] Working principle:

[0031] Different anchor nut storage boxes are selected according to the anchor nuts of different specifications. When the anchor nuts are inserted into the column 3, the staff can screen out the anchor nuts of different specifications in time by observing whether the anchor nuts can pass through the column 3 smoothly and the storage situation of the anchor nuts on the adjacent columns, so as to prevent the problem of storage confusion during the storage process.

[0032] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
