Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Example

Figure 1 is a structural diagram of a fast bolt loading and unloading device provided in the embodiment of the present application

As shown in FIG. 1 , the bolt quick loading and unloading device provided in this embodiment includes a fixed rod 10 , a transmission rod 20 and a clip 30 , which are fixedly connected together in sequence, and keep the central axes of the three coincide with each other.

Fixing bar 10 is a cylindrical iron column, can select suitable steel bar or wire rod for use during making, and its diameter preferably 8 millimeters, can be placed in the drill chuck of electric drill like this, if too thin meeting clamping is not tight, too It may be too thick to be clamped by the drill chuck, and its length is preferably 28mm.

One end of the fixed rod 10 that needs to penetrate into the drill chuck needs to be polished with an emery wheel, so as to eliminate the burrs caused by cutting steel bars or wire rods during processing, and avoid causing damage to the electric drill.

The transmission rod 20 is used to connect the fixed rod 10 with the clip 30, and its diameter needs to be thicker than that of the fixed rod 10 to increase the strength. The transmission rod 20 can be processed with a cylindrical profile, its diameter is preferably 25 mm, and its length is preferably 40 mm.

One end of the transmission rod 20 and one end of the fixed rod 10 are connected together by welding, and attention should be paid to coincide their axes during processing, otherwise eccentric vibration will be caused during use, and even cannot be used when the eccentric distance is large.

The clip 30 is preferably a circular cylinder with a length of 33 mm, one end of which is connected to the other end of the transmission rod 20 by welding, and it is also necessary to pay attention to that the central axes of the two must coincide during processing, otherwise it will cause eccentric vibration until it cannot use.

A nut bayonet 31 is provided at the other end of the clip 30 , and the nut bayonet 31 is used for fastening a nut or a nut of a bolt, as shown in FIG. 2 .

When using this device, first the drill chuck of the electric drill is opened, then the fixed rod 10 is stretched into the opened drill chuck, and then the drill chuck is fastened; then the nut bayonet 31 of the clip 30 The nuts or nuts of the bolts that need to be dismantled or installed are stuck, and the electric drill is started to tighten the nuts or nuts. Because the electric drill has a forward and reverse function, the nut or nut can be loosened by controlling the reverse of the electric drill.

It can be seen from the above technical solutions that this embodiment provides a fast bolt loading and unloading device. The device includes a fixed rod, a transmission rod and a clip, the three are fixedly connected in sequence, and the central axes of the three are kept coincident with each other, the fixed rod is used to be fixed to the drill chuck of the electric drill, and the clip is provided with a nut bayonet. When it is necessary to install or remove bolts for maintenance of electric facilities, fix the fixing rod of this device in the drill chuck of the electric drill, and then clamp the nut or nut of the bolt with the bayonet, start the electric drill, and set the steering angle of the electric drill The bolts can be fastened or disassembled, because the electric drill has a higher speed, and the bolts can be fastened or disassembled at a higher speed, which is much more efficient than manual tightening or dismantling of the bolts with a wrench, so the installation or disassembly can be greatly improved. bolt efficiency.

In order to meet the loading and unloading requirements of bolts of different sizes, the nut bayonet 31 of the clip 30 of the bolt quick loading and unloading device provided in this embodiment can be of various sizes. Generally, the nominal diameter of electric facilities is more than 25 mm, 35 mm or 50 mm nut, for this reason, the nut bayonet 31 of the clip 30 can be any of the aforementioned sizes.

For the convenience of construction, it is also possible to manufacture one fast bolt loading and unloading device of the above three sizes, which can be carried as a complete set of tools when on-site maintenance of electric facilities, which can meet the loading and unloading of bolts of different sizes.

In addition, the clip 30 and the transmission rod 20 are also flexibly connected for selection, and a square cylinder (not shown) is arranged at the opposite end of the transmission rod 20 and the fixed rod 10; A square bayonet (not shown) is arranged at the end, and the outer diameter of the square cylinder matches the inner diameter of the square bayonet, so that different bolts can be adjusted by replacing the clip 30 with the nut bayonet 31 of different sizes. for installation or removal.

In this embodiment, the electric drill used to install the bolt quick installation tool is preferably a hand drill, and the hand drill can be equipped with a rechargeable battery, so that when working in the field, the operation can be carried out without an external power supply, which expands the functions of the bolt quick installation device. scope of use.

When it is necessary to drill a hole in a plank or an iron plate, the bolt quick loading and unloading device in this embodiment can also be removed, and then the drill bit can be loaded on to carry out the drilling operation.
