[0003] Currently, electric bolt removal devices have been developed, which use electric drills to loosen bolts and remove them. However, since bolts are often used in conjunction with washers, washers are very easy to fall off and be lost after the bolts are loosened, causing inconvenience to workers in picking them up and also causing property losses. Utility Model Content

[0004] In view of the defects in the prior art, the purpose of the present utility model is to provide an electric bolt removal device based on a photovoltaic bracket, which can prevent the washers from falling and being lost.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an electric bolt removal device based on a photovoltaic bracket for removing bolts, comprising an electric drill and also comprising:

In the description of this utility model, "plurality" means more than two, unless otherwise specifically defined.

[0027] like Figure 1-Figure 5 As shown, the utility model provides an electric bolt removal device based on a photovoltaic bracket, which is used to remove bolts 50, including an electric drill 10, a rotating shaft 20, a connecting shaft 30 and a clamping mechanism 40.

[0028] A limiting groove 21 extending inward is formed on the front end surface of the rotating shaft 20 , and the limiting groove 21 is adapted to the head of the bolt 50 .

[0029] The connecting shaft 30 is fixedly connected to the rotating shaft 20 and the output shaft of the electric drill 10 , and the connecting shaft 30 , the rotating shaft 20 and the output shaft of the electric drill 10 are coaxially arranged.

[0030] The clamping mechanism 40 includes a fixed plate 41, a guide rod, an L-shaped plate 42, a spring 43, and a limit plate 44. The fixed plate 41 is disposed on the outside of the rotating shaft 20. The first end of the guide rod is fixedly connected to the fixed plate 41, and the second end of the guide rod is inserted into the guide hole 22 on the rotating shaft 20 and is in sliding contact with the inner wall of the guide hole 22. The first end of the L-shaped plate 42 is fixedly connected to the fixed plate 41, and the second end of the L-shaped plate 42 is located in front of the rotating shaft 20 and extends inward. The spring 43 causes the fixed plate 41 to have a tendency to approach the rotating shaft 20. The first end of the limit plate 44 is fixedly connected to the housing 11 of the electric drill 10, and the second end of the limit plate 44 is in contact with the inner side surface of the first end of the L-shaped plate 42.

[0031] In the initial state, the second end of the limiting plate 44 contacts the inner side surface of the first end of the L-shaped plate 42 .

[0032] The specific working process of this device is:

[0033] First, the staff fits the limiting groove 21 on the rotating shaft 20 with the head of the bolt 50 .

[0034] The operator then starts the electric drill 10. The output shaft of the electric drill 10 rotates the rotating shaft 20 via the connecting shaft 30, which in turn rotates the bolt 50, thereby loosening the bolt 50. As the rotating shaft 20 rotates, the fixing plate 41 disengages from the limiting plate 44. Under the action of the spring 43, the L-shaped plate 42 moves inward, clamping the washer 51 between the L-shaped plate 42 and the rotating shaft 20. The washer 51 is then removed along with the bolt 50, thus preventing the washer 51 from falling or being lost.

[0035] Finally, the staff takes out the electric drill 10, and the bolt 50 and the washer 51 will be removed together, completing the disassembly of the bolt 50 on the photovoltaic bracket.

[0036] In one embodiment, a guide surface 45 is formed on the end surface of the second end of the L-shaped plate 42 and is inclined outward and extends backward.

[0037] The fixing plate 41 will be out of contact with the limiting plate 44 , and under the action of the spring 43 , due to the design of the guide surface 45 , the washer 51 will be more easily scooped up and enter between the L-shaped plate 42 and the rotating shaft 20 .

[0038] In one embodiment, there are two clamping mechanisms 40 , and the two clamping mechanisms 40 are respectively located on both sides of the rotating shaft 20 .

[0039] In this way, the two clamping mechanisms 40 can respectively clamp the two sides of the washer 51, thereby improving the stability of the device.

[0040] In one embodiment, an insert rod 23 is fixedly mounted on the rear end surface of the rotating shaft 20 . The insert rod 23 is coaxially arranged with the rotating shaft 20 , and a threaded hole 24 is formed on the outer peripheral surface of the insert rod 23 .

[0041] The front end surface of the connecting shaft 30 is provided with an inwardly extending socket 31, which is adapted to the insertion rod 23. A screw 32 is provided on the connecting shaft 30, and the threaded end of the screw 32 passes through the connecting shaft 30 and is threadedly matched with the threaded hole 24 on the insertion rod 23.

[0042] After removing the screw 32, the operator can remove the rotating shaft 20 for replacement by inserting the rod 23 on the new rotating shaft 20 into the socket 31 on the connecting shaft 30 and threading the threaded end of the screw 32 into the threaded hole 24 on the rod 23. The retaining groove 21 on each rotating shaft 20 is of different sizes, which can improve the versatility of the device and enable the device to remove bolts 50 of different sizes.

[0043] In one embodiment, a front end surface of the connecting shaft 30 is provided with a positioning groove 33 extending inward.

[0044] A positioning block 25 is fixedly mounted on the outer circumference of the insertion rod 23 , and the positioning block 25 is adapted to the positioning groove 33 .

[0045] When replacing the rotating shaft 20, insert the insertion rod 23 on the new rotating shaft 20 into the socket 31 on the connecting shaft 30, and insert the positioning block 25 into the positioning groove 33. At this time, the threaded end of the screw 32 will be aligned with the threaded hole 24 on the insertion rod 23, making it convenient to subsequently thread the threaded end of the screw 32 into the threaded hole 24 on the insertion rod 23.

[0046] In one embodiment, the spring 43 is sleeved on the guide rod, and both ends of the spring 43 are fixedly connected to the fixing plate 41 and the rotating shaft 20 respectively.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all points of view, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
