Description

Technical Field

[0001] This application relates to the technical field of construction tools, and in particular to a handheld electric drill stand. Background Technology

[0002] Photovoltaic brackets are mounting frames used to support photovoltaic panels. They need to withstand various external forces such as the weight of the photovoltaic panels themselves, wind loads, and snow loads. The structural stability is directly related to the safety and service life of the photovoltaic system.

[0003] In existing technologies, photovoltaic support systems typically consist of multiple columns and support components. During the construction of photovoltaic support systems, drilling is required on the surface of the round steel pipes of the columns to connect the columns with the other support components.

[0004] In existing technology, workers typically use handheld electric drills to drill holes in the outer surface of round steel pipes. However, since the curved surface of the round steel pipe lacks flat support points, the drill bit is difficult to stably fit against the preset drilling position, causing the drill bit to easily slip on the outer surface of the steel pipe. This results in a deviation between the actual drilling position and the designed position, reducing the accuracy of the drilling and presenting significant shortcomings. Utility Model Content

[0005] To improve the accuracy of drilling operations, this application provides a handheld electric drill stand.

[0006] The handheld electric drill stand provided in this application adopts the following technical solution: A handheld electric drill holder includes a drilling section, which includes an electric drill body. The electric drill body is provided with a handle, and the handle is provided with a binding strap. It also includes a mounting frame, which is fitted onto the outer surface of the drilling section. The mounting frame is provided with a mounting rod, and the binding strap is wrapped around the mounting rod and tied to the mounting rod with a rope. The mounting frame is provided with a connecting rod, and the connecting rod is provided with a steel bar hook, which is hooked and engaged with a column.

[0007] By adopting the above technical solution, during drilling, the worker places the mounting frame on the drilling section, then wraps the binding strap around the mounting rod and uses rope to secure the drilling section. After securing, the worker hooks the rebar hook onto the column, aligns the drill bit of the electric drill body with the drilling position, holds the handle, and presses the button to drill. During the drilling process, the mounting frame forms a stable connection with the column through the rebar hook, providing a support point for the drilling operation, thereby reducing the possibility of the drill bit slipping on the arc surface, reducing the deviation between the actual drilling position and the design position, and thus improving the accuracy of the drilling operation.

[0008] Optionally, a limiting component is provided on the mounting frame. The limiting component includes a first limiting rod and a limiting band arranged along the width direction of the mounting frame. The first limiting rod and the limiting band are respectively arranged on opposite sides of the electric drill body, and the first limiting rod and the limiting band abut against the upper end surface of the electric drill body.

[0009] By adopting the above technical solution, during drilling, the drilling part and the mounting frame are lifted by the handle, making it less likely for the whole to shift downwards. At the same time, the first limiting rod and the limiting band restrict the upward displacement of the drill bit body, thus forming a limiting constraint on the drill bit body in the vertical direction, reducing drilling deviation caused by vertical shaking, and further improving the accuracy of drilling operations.

[0010] Optionally, the limiting component further includes two second limiting rods disposed along the length direction of the mounting frame, the two second limiting rods being disposed on opposite sides of the handle, and the two second limiting rods abutting against the outer surface of the handle.

[0011] By adopting the above technical solution, the two second limiting rods abut against each other from both sides of the handle, which can effectively limit the horizontal displacement of the drilling part, thereby reducing the drilling deviation caused by the horizontal shaking of the drilling part and further improving the accuracy of drilling operations.

[0012] Optionally, the outer surface of the mounting frame is provided with two guide rods, which are parallel to the length direction of the mounting frame and abut against the outer surfaces of the radial sides of the column.

[0013] By adopting the above technical solution, before drilling, the worker abuts two guide rods against the outer surface of the column to form a radial constraint on the installation frame, limiting the offset of the installation frame in the radial direction of the column, thereby reducing the deviation of the drill bit from the drilling direction caused by the shaking of the installation frame, and further improving the accuracy of the drilling operation.

[0014] Optionally, the rebar hook can be detachably connected to the connecting rod via a connecting assembly.

[0015] By adopting the above technical solution, when the specifications of the column to be drilled change, the worker can replace the steel bar hooks with those that are compatible with the column specifications through the connecting components. This allows the steel bar hooks to be stably attached to the outer surface of the column, ensuring the connection between the installation frame and the column and improving the adaptability of the electric drill frame.

[0016] Optionally, the connecting rod has a connecting groove for the end of the rebar hook to be inserted. The connecting assembly includes a pin rod. The rebar hook and the inner sidewall of the connecting groove have interconnected insertion grooves. The pin rod slides through the insertion groove. One end of the pin rod is provided with a limit block, and the other end extends out of the insertion groove and is threaded with a locking nut. The locking nut and the limit block abut against the outer surface of the connecting rod.

[0017] By adopting the above technical solution, when disassembly is required, the worker unscrews the locking nut, then pulls the pin out of the insertion slot, and finally pulls the rebar hook out of the connection slot to achieve disassembly; during installation, the worker first inserts the end of the new rebar hook into the connection slot, then holds the limiting block to insert the insertion post into the insertion slot. When the limiting block abuts against the end face of the connection post, the worker tightens the locking nut to achieve the connection between the rebar hook and the installation frame.

[0018] Optionally, the mounting frame is provided with an adjustment assembly, which includes an adjustment plate on the mounting frame. The adjustment plate has an adjustment groove, and a bidirectional lead screw is rotatably connected inside the adjustment groove. The ends of the two guide rods are each provided with an adjustment block that is slidably connected inside the adjustment groove. The two adjustment blocks are respectively threaded to the two ends of the bidirectional lead screw with opposite thread directions.

[0019] By adopting the above technical solution, the worker rotates the bidirectional lead screw. Under the limit of the adjustment groove and the adjustment block, the bidirectional lead screw drives the two adjustment blocks to move away from or closer to each other along the direction of the adjustment groove, thereby realizing the adjustment of the distance between the two guide columns. This allows the guide columns to fit against the outer surface of columns with different diameter specifications, thus ensuring the limiting effect of the guide columns on the installation frame and improving the adaptability of the electric drill frame.

[0020] Optionally, the end of the bidirectional lead screw extends out of the adjustment groove and is coaxially fixed with a handwheel.

[0021] By adopting the above technical solution, the handwheel makes it easy for workers to rotate the bidirectional lead screw, thereby realizing the adjustment of the guide column spacing.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up an installation frame and steel bar hooks, the installation frame forms a stable connection with the column through the steel bar hooks during the drilling process, providing a support point for the drilling operation, thereby reducing the possibility of the drill bit slipping on the arc surface, reducing the deviation between the actual drilling position and the design position, and thus improving the accuracy of the drilling operation. 2. This application sets up a limiting component, which works in conjunction with the lifting operation of the handle to form a dual constraint on the drilling part in both the horizontal and vertical directions, thereby reducing the possibility of drilling deviation caused by the shaking of the drilling part and improving the accuracy of drilling operations. 3. By setting up a connecting component and an adjusting component, when the specifications of the column change, the worker can replace the steel bar hook with one that matches the specifications of the column through the connecting component, so that the steel bar hook can be stably attached to the outer surface of the column. Then, the worker can adjust the distance between the two guide columns through the adjusting component, so that the guide columns can be attached to the outer surface of columns with different diameter specifications, thereby ensuring the limiting effect of the guide columns on the installation frame, thus improving the adaptability of the electric drill frame.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a handheld electric drill holder. Example

[0030] Reference Figure 1 and Figure 2A handheld electric drill holder includes a mounting frame 1, which is constructed by welding multiple columns 01. The mounting frame 1 has a drilling section 2 inside, which includes an electric drill body 21. A handle 22 for easy gripping is fixedly installed on the electric drill body 21. A binding strap 23 is fixedly connected to the end of the handle 22 away from the electric drill body 21. The mounting frame 1 is sleeved on the outer surface of the drilling section 2.

[0031] Reference Figure 1 and Figure 2 An installation rod 101 is fixedly connected to the installation frame 1. The installation rod 101 is L-shaped. When connecting the installation frame 1 and the drilling part 2, the worker wraps the binding strap 23 around the installation rod 101 and then ties the installation rod 101 and the binding strap 23 with a rope.

[0032] Reference Figure 1 and Figure 2 A steel bar hook 3 is fixedly welded to the mounting frame 1. The steel bar hook 3 is hooked and engaged with the column 01. After the drilling part 2 is installed, the worker hooks the steel bar hook 3 onto the column 01, aligns the drill bit of the electric drill body 21 with the drilling position, holds the handle 22 and presses the button to drill. During the drilling process, the mounting frame 1 forms a stable connection with the column 01 through the steel bar hook 3, providing a support point for the drilling operation, thereby reducing the possibility of the drill bit slipping on the arc surface, reducing the deviation between the actual drilling position and the design position, and thus improving the accuracy of the drilling operation.

[0033] Reference Figure 1 and Figure 2 A limiting component 4 is provided on the mounting frame 1. The limiting component 4 includes a first limiting rod 41, a limiting band 42 and a second limiting rod 43, which are fixedly welded to the mounting frame 1. The first limiting rod 41 and the limiting band 42 are arranged along the width direction of the mounting frame 1 and distributed on opposite sides of the electric drill body 21. The first limiting rod 41 and the limiting band 42 abut against the upper end face of the electric drill body 21.

[0034] Reference Figure 1 and Figure 2 There are two second limiting rods 43. The two second limiting rods 43 are arranged along the length of the mounting frame 1 and distributed on opposite sides of the handle 22. The two second limiting rods 43 abut against the outer surface of the handle 22.

[0035] During the drilling process, the drilling section 2 and the mounting frame 1 are lifted by the handle 22, making it difficult for the whole to shift downwards. The first limiting rod 41 and the limiting band 42 restrict the upward displacement of the drill bit body. The two second limiting rods 43 abut from both sides of the handle 22, which can effectively limit the horizontal displacement of the drilling section 2. This limiting effect, together with the lifting operation of the handle 22, forms a double constraint on the drilling section 2 in both the horizontal and vertical directions, thereby reducing the possibility of drilling deviation caused by the shaking of the drilling section 2 and improving the accuracy of the drilling operation.

[0036] Reference Figure 1 and Figure 2 Two guide rods 5 are fixedly welded to the surface of the mounting frame 1 facing the column 01. The two guide rods 5 are set parallel to the length direction of the mounting frame 1. Before drilling, the worker abuts the two guide rods 5 against the outer surface of the radial sides of the column 01 to form a radial constraint on the mounting frame 1, which restricts the offset of the mounting frame 1 in the radial direction of the column 01, thereby reducing the deviation of the drill bit from the drilling direction caused by the shaking of the mounting frame 1.

[0037] The implementation principle of a handheld electric drill frame in this application embodiment is as follows: When drilling, the worker places the mounting frame 1 on the drilling part 2, then wraps the binding strap 23 around the mounting rod 101, and uses rope to tie it to fix the drilling part 2. After fixing, the worker hooks the steel bar hook 3 onto the column 01, aligns the drill bit of the electric drill body 21 with the drilling position, holds the handle 22 and presses the button to drill. During the drilling process, the mounting frame 1 forms a stable connection with the column 01 through the steel bar hook 3, providing a support point for the drilling operation, thereby reducing the possibility of the drill bit slipping on the arc surface, reducing the deviation between the actual drilling position and the design position, and thus improving the accuracy of the drilling operation. Example

[0038] Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the rebar hook 3 is detachably connected to the connecting rod 102 via the connecting assembly 6, and the connecting rod 102 has a connecting groove 7 for inserting the end of the rebar hook 3.

[0039] Reference Figure 3 and Figure 4 The connecting component 6 includes a pin rod 61, a steel bar hook 3, and a connecting groove 7. The inner wall of the connecting groove 7 has interconnected insertion grooves (not shown in the figure). The insertion grooves are parallel to the radial direction of the connecting rod 102. The pin rod 61 slides through the insertion groove. One end of the pin rod 61 is fixedly connected to a limit block 62, and the other end extends out of the insertion groove and is threadedly connected to a locking nut 63. The locking nut 63 and the limit block 62 abut against the outer surface of the connecting rod 102.

[0040] When the specifications of the column 01 to be drilled change, the worker unscrews the locking nut 63, then pulls the pin rod 61 out of the insertion slot, and finally pulls the rebar hook 3 out of the connecting slot 7 to disassemble it. When installing the rebar hook 3 that matches the specifications of the column 01, the worker first inserts the end of the new rebar hook 3 into the connecting slot 7, then holds the limiting block 62 and inserts the insertion post into the insertion slot. When the limiting block 62 abuts against the end face of the connecting post, the worker tightens the locking nut 63 to connect the rebar hook 3 to the mounting frame 1. This allows the rebar hook 3 to be stably attached to the outer surface of the column 01, ensuring the connection between the mounting frame 1 and the column 01 and improving the compatibility of the electric drill frame.

[0041] Reference Figure 3 and Figure 4 An adjustment component 8 is provided on the mounting frame 1. The adjustment component 8 includes an adjustment plate 81 fixedly welded to the mounting frame 1. An adjustment groove 9 is provided on the adjustment plate 81 along the width direction of the mounting frame 1. A bidirectional lead screw 82 is rotatably connected inside the adjustment groove 9. The end of the bidirectional lead screw 82 extends out of the adjustment groove 9 and is coaxially fixedly connected to a handwheel 83.

[0042] Reference Figure 3 and Figure 4 Both guide rods 5 are fixedly connected to adjusting blocks 84 that are slidably connected in adjusting grooves 9. The cross-sections of adjusting blocks 84 and adjusting grooves 9 are T-shaped. The two adjusting blocks 84 are threadedly connected to the two ends of the bidirectional lead screw 82 with opposite thread directions.

[0043] When the specifications of column 01 are changed, the worker rotates the double-acting screw 82. Under the limit of the adjusting groove 9 and the adjusting block 84, the double-acting screw 82 drives the two adjusting blocks 84 to move away from or closer to each other along the direction of the adjusting groove 9, thereby realizing the adjustment of the distance between the two guide columns. This allows the guide columns to fit against the outer surface of columns 01 with different diameter specifications, thus ensuring the limiting effect of the guide columns on the mounting frame 1 and further improving the adaptability of the electric drill frame.

[0044] The implementation principle of Example 2 is as follows: When the specifications of column 01 change, the worker replaces the steel bar hook 3 with a steel bar hook 3 that is compatible with the specifications of column 01 through the connecting component 6, so that the steel bar hook 3 can be stably attached to the outer surface of column 01. Then, the worker adjusts the distance between the two guide columns through the adjusting component 8, so that the guide columns can be attached to the outer surface of column 01 with different diameter specifications, thereby ensuring the limiting effect of the guide columns on the installation frame 1, thus improving the adaptability of the electric drill frame.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
