Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic bracket installation, and in particular relates to a photovoltaic bracket installation wrench device. Background Art

[0002] The photovoltaic bracket commonly used on sloping roofs is the U41X62X2.0 model photovoltaic bracket, which is connected to the aluminum alloy photovoltaic clamp on the steel roof with bolts.

[0003] During the photovoltaic bracket installation process, the hidden location between the photovoltaic bracket and the steel roof makes it difficult to place the nuts and mounting screws and align them with the mounting holes. Specifically, the bolts that secure the photovoltaic bracket are usually installed by holding the nuts at the bottom with your hand and tightening the bolts from above with a wrench.

[0004] There are usually the following states when the bolts are tightened:

[0005] 1. The bolts and nuts are tightened and the spring washers are flattened;

[0006] 2. When tightening the bolt, the bottom nut and bolt rotate together, resulting in ineffective tightening. If the bolt is loosened, the bolt and nut will basically rotate synchronously, making it difficult to loosen. If the bottom nut is tightened with a wrench, the clearance is small and the operation is difficult. Even if the operation is done properly, removing the nut is time-consuming and laborious.

[0007] Furthermore, during the actual installation process, since there are many types of bolts to be installed, it is necessary to frequently replace wrenches of different types during the actual installation process. Utility Model Content

[0008] Based on the above background, the purpose of the present invention is to provide a photovoltaic bracket installation wrench device.

[0009] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0010] A photovoltaic bracket installation wrench device includes a wrench bracket, the wrench bracket includes an upper bracket part and a lower bracket part, and the upper bracket part and the lower bracket part are assembled and connected by a spring structure;

[0011] The upper bracket portion is rotatably connected to an upper rotating rod, and the bottom of the upper rotating rod is equipped with an upper screw head for plugging into the screw head;

[0012] The lower bracket portion is fixedly assembled with a lower nut placement mechanism used in conjunction with the upper screw head;

[0013] The lower nut placement mechanism includes a fixing seat fixedly mounted on the lower bracket portion, the top of the fixing seat is rotatably connected to a rotary adjustment frame, and the rotary adjustment frame is fixedly connected to a plurality of nut barrels for placing nuts of different models;

[0014] The nut barrel is provided with a limiting groove for limiting the nut.

[0015] Preferably, the upper bracket portion includes an upper vertical bracket portion, an upper horizontal bracket portion is integrally formed on the upper end of the upper vertical bracket portion, a rotating connecting seat is fixedly connected to the upper horizontal bracket portion, and the upper rotating rod is rotatably connected to the rotating connecting seat.

[0016] Preferably, a bearing is installed in the rotating connecting seat, and the upper rotating rod is fixedly installed on the inner ring of the bearing.

[0017] Preferably, the lower bracket portion includes a lower vertical bracket portion, the lower vertical bracket portion is integrally formed with a lower horizontal bracket portion, the outer end of the lower horizontal bracket portion is integrally formed with a vertically arranged upper vertical portion, and the fixing seat is fixedly connected to the upper vertical portion;

[0018] The bottom of the rotation adjustment frame is fixedly connected with a rotation shaft which is rotatably connected to the fixing seat.

[0019] Preferably, an oblique bracket is welded between the upper vertical portion and the lower horizontal bracket portion.

[0020] Preferably, the upper vertical bracket portion is slidably connected within the lower vertical bracket portion;

[0021] The spring structure comprises spring seats respectively fixedly connected to the upper vertical support portion and the lower vertical support portion, and a telescopic spring is fixedly connected between the spring seats;

[0022] The lower end of the upper vertical bracket part and the upper end of the lower vertical bracket part are sleeved in the telescopic spring.

[0023] Preferably, the rotary adjustment frame has a plurality of connection ends, and a nut barrel is fixedly connected to each of the connection ends.

[0024] Preferably, a connector is fixedly connected to the top of the upper rotating rod, and a hexagonal slot is provided in the connector.

[0025] Preferably, a locking screw structure for locking the rotation adjustment frame is installed on the top of the fixing seat;

[0026] When the rotary adjustment frame is rotated to the position where the nut barrel of the corresponding model is located below the upper screw head, it is locked in position by the locking screw structure;

[0027] The locking screw structure includes a pair of locking screws separated at two sides of the rotation adjustment frame.

[0028] The utility model has the following beneficial effects:

[0029] 1. During the working process, the installation position of the photovoltaic bracket is inserted between the upper screw head and the nut barrel. The operator rotates the fixing seat in advance according to the model of the nut to switch the nut barrel of the corresponding model to the bottom of the upper screw head. At this time, the screw head of the mounting screw is inserted into the upper screw head, and the upper rotating rod is driven to rotate by a wrench or electric screwdriver.

[0030] Since the nut is pre-placed in the nut tube, the operator does not need to support the nut with one hand and operate the installation screw with the other hand, and the hidden installation position is relatively hidden. This method makes it easy to align the nut with the installation hole on the photovoltaic bracket, thereby facilitating installation.

[0031] 2. During the working process, the operator presses the upper bracket and the lower bracket. At this time, the spring is compressed, and the downward pressure is always maintained during the process of twisting the installation screw, so that the installation screw is installed and lowered at the same time. After the installation is completed, the pressing force is released. At this time, the upper bracket and the lower bracket quickly move away from each other under the restoring force of the spring, and then quickly detach from the installation screw and the limiting installation nut to complete the installation.

[0032] 3. During operation, when it is necessary to rotate and adjust the nut barrels of different models, screw the locking screw down until the top is lower than the bottom of the rotary adjustment frame (maintain a certain distance between the rotary adjustment frame and the fixed base). This will not affect the rotation of the rotary adjustment frame. After adjusting the position, raise the locking screw to the spacers on both sides of the rotary adjustment frame. Under the spacers, when turning the screw, the rotary adjustment frame remains in a locked position, thereby ensuring that it does not rotate during installation, effectively increasing installation efficiency.

[0042] Example 1

[0043] like Figure 1-4 As shown, a photovoltaic bracket installation wrench device includes a wrench bracket, and the wrench bracket includes an upper bracket part and a lower bracket part. The upper bracket part and the lower bracket part are assembled and connected by a spring structure.

[0044] Specifically, the upper bracket part is rotatably connected to the upper rotating rod 2, and the bottom of the upper rotating rod 2 is equipped with a screw head 3 for plugging into the screw head (the screw head 3 is provided with a hexagonal groove with a limited position on the screw head, which is adapted to the shape of the screw head).

[0045] During actual working process, the top of the screw head 3 is fixedly connected to the screw, and the screw is fastened to the bottom of the upper rotating rod 2. The tightening direction of the thread is the same as the tightening direction of the upper rotating rod 2, so as to realize the replacement of different models of screw heads on different models of screws (most of the screw heads are universal models).

[0046] Specifically, the upper bracket portion includes an upper vertical bracket portion 1, the upper end of which is integrally formed with an upper horizontal bracket portion. A rotating connection seat 11 is fixedly connected to the upper horizontal bracket portion, and the upper rotating rod 2 is rotatably connected to the rotating connection seat 11. A bearing is installed in the rotating connection seat 11, and the upper rotating rod 2 is fixedly mounted on the inner ring of the bearing 111.

[0047] At the same time, the top of the upper rotating rod 2 is fixedly connected to a connector 21, and a hexagonal slot is provided in the connector 21. During operation, a hexagonal wrench or an electric screwdriver is inserted into the hexagonal slot to rotate the upper rotating rod 2 and tighten the thread.

[0048] At the same time, in order to limit the nut, a lower nut placement mechanism used in conjunction with the upper screw head 3 is fixedly assembled and connected on the above-mentioned lower bracket part.

[0049] Specifically, the lower nut placement mechanism includes a fixed seat 54 fixedly mounted on the lower bracket portion, the top of the fixed seat 54 is rotatably connected to a rotary adjustment frame 51, and the rotary adjustment frame 51 is fixedly connected to a number of nut tubes 53 for placing nuts of different models; a limiting groove for a limiting nut is provided on the nut tube 53.

[0050] Specifically, different types of hexagonal limiting grooves are provided in different nut barrels 53 so that nuts with different proportions can be placed and limited in the limiting grooves during operation.

[0051] Specifically, the bottom of the rotating adjustment frame 51 is fixedly connected to a rotating shaft that is rotatably connected to the fixed base 54. According to the existing method, the rotating shaft is rotatably connected to the top center position of the fixed base 54. For example, a mounting groove is opened at the top center position of the fixed base 54, and a bearing is installed in the mounting groove, and the rotating shaft is fixed to the inner ring of the bearing.

[0052] The rotation adjustment frame 51 has a plurality of connection ends 52, each of which is fixedly connected to a nut barrel 53. The nut barrel 53 has a groove 531 such as a hexagonal groove for limiting the nut.

[0053] During the operation, the installation position of the photovoltaic bracket is extended between the upper screw head 3 and the nut tube 53. The operator rotates the fixing seat 54 in advance according to the model of the nut to switch the nut tube 53 of the corresponding model to be located below the upper screw head 3. At this time, the screw head of the installation screw is extended into the upper screw head 3, and the upper rotating rod 2 is driven to rotate by a wrench or electric screwdriver. During the rotation process, the installation screw is installed on the photovoltaic bracket.

[0054] Since the nut is pre-placed in the nut tube 53, the operator does not need to support the nut with one hand and operate the installation screw with the other hand, and the hidden installation position is relatively hidden. This method makes it easy to align the nut with the installation hole on the photovoltaic bracket, thereby facilitating installation.

[0055] The lower bracket portion includes a lower vertical bracket portion 33, which is integrally formed with a lower horizontal bracket portion 4. The outer end of the lower horizontal bracket portion 4 is integrally formed with a vertically disposed upper vertical portion, to which the fixing seat 54 is fixedly connected. Furthermore, an inclined bracket 41 is welded between the upper vertical portion and the lower horizontal bracket portion 4 (the inclined bracket 41 is used for reinforcement).

[0056] The above-mentioned upper vertical bracket part 1 is slidably connected in the lower vertical bracket part 33 (an adaptive sliding cavity is opened in the lower vertical bracket part 33); during the working process, the sliding connection is realized, and as the installation screw is continuously lowered (tightened into the nut), the upper bracket part is continuously pressed down to cooperate with the advancement of the installation screw.

[0057] Example 2

[0058] like Figure 1-4 As shown, based on the structure of Example 1, in order to facilitate the installation of the screw and the nut during the installation process, the installation screw is lowered, and the above-mentioned spring structure includes spring seats 31 respectively fixedly connected to the upper vertical bracket part 1 and the lower vertical bracket part 33, and a telescopic spring 32 is fixedly connected between the spring seats 31; specifically, the lower end of the upper vertical bracket part 1 and the upper end of the lower vertical bracket part 33 are sleeved in the telescopic spring 32.

[0059] During the operation, the operator presses the upper bracket part and the lower bracket part. At this time, the telescopic spring 32 is compressed, and the downward pressure is always maintained during the process of twisting the installation screw, so as to promote the installation screw to descend while being installed. After the installation is completed, the pressing force is released. At this time, the upper bracket part and the lower bracket part quickly move away from each other under the restoring force of the telescopic spring 32, and then quickly detach from the installation screw and the limiting installation nut to complete the installation.

[0060] Example 3

[0061] like Figure 1-4As shown, this embodiment builds on the structure of Example 2. To prevent the rotating adjustment frame 51 from rotating during the screw tightening process, a locking screw structure is mounted on the top of the fixing seat 54. This structure is used to lock the rotating adjustment frame 51. When the rotating adjustment frame 51 is rotated to a position where the corresponding nut barrel 53 is located below the upper screw head 3, the locking screw structure locks the frame in place. Specifically, the locking screw structure includes a pair of locking screws 6 that block the rotating adjustment frame 51 on either side.

[0062] During operation, when it is necessary to rotate and adjust the nut barrel 53 of a different size, the locking screw 6 is screwed down until the top is lower than the bottom of the rotating adjustment frame 51 (a certain distance is maintained between the rotating adjustment frame 51 and the fixing seat 54). This does not affect the rotation of the rotating adjustment frame 51. After adjusting the position, the locking screw 6 is raised to block the two sides of the rotating adjustment frame 51. Under the block, the rotating adjustment frame 51 remains locked in place while the screw is turned, thereby ensuring that it does not rotate during installation, effectively improving installation efficiency.

[0063] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
