Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically to a device for drilling holes in photovoltaic brackets. Background Technology

[0002] In the assembly of photovoltaic (PV) brackets, drilling is often involved. The traditional drilling process involves on-site surveyors marking the locations on the PV brackets to be drilled according to work instructions. Then, construction workers carry the drilling equipment and drill at the corresponding marks. This method has relatively little negative impact on drilling quality and the drilling equipment for a small number of drilling operations. However, when large-scale drilling is required, it has been found to have significant negative impacts on both the drilling operation and the drilling equipment itself. The reasons are as follows: 1. Regarding hole quality, it is difficult for drilling workers to maintain a fixed posture for extended periods, causing the drill bit to shift, resulting in drilling direction deviation, reduced drilling accuracy, and excessively large holes; 2. The drilling equipment needs to be held and kept in the same position for a long time, which places high demands on the worker's physical strength. Workers are prone to fatigue during prolonged work, causing the drilling equipment to shift and affecting hole quality; 3. During the drilling process, the worker's strength decreases, causing the drill bit to shift direction, ultimately subjecting the drill bit to shear stress, which can easily lead to drill bit breakage and deformation.

[0003] In some current photovoltaic bracket drilling devices, lightweight, long-endurance drilling tools are gradually being considered for operation. These tools can solve the above problems to some extent, but the effect is not good, especially when long-term construction work is required, the above problems will also occur. In addition, the purchase and maintenance costs of such lightweight, long-endurance equipment are also high, which makes the construction cost increase sharply. Utility Model Content

[0004] To address the problems of poor hole quality, excessive physical demands on construction workers, easy deformation and breakage of drill bits, and high procurement and maintenance costs of drilling equipment, this utility model provides a drilling device for photovoltaic brackets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drilling device for photovoltaic mounting brackets, comprising:

[0007] A drilling assembly, wherein fixed handles are fixedly provided on both the left and right sides of the drilling assembly;

[0008] A connecting beam is fixedly connected to the side of the drilling assembly, and the length direction of the connecting beam is along the length direction of the impact drill bit of the drilling assembly. The end of the connecting beam away from the impact drill bit of the drilling assembly is extended to form an auxiliary part, and a stop bolt is fixedly connected to the top of the connecting beam.

[0009] A pull rope component, one end of which is connected to a stop bolt, and the other end of which is connected to a photovoltaic bracket;

[0010] The pull rope component includes: a rigid rope and an elastic rope arranged in parallel, with a first end of the rigid rope and the first end of the elastic rope connected together to a first hook, and a second end of the rigid rope and the second end of the elastic rope connected together to a second hook.

[0011] The length of an elastic rope in its natural state is less than the length of a rigid rope.

[0012] As a further description of the above technical solution:

[0013] Multiple stop bolts are provided along the length of the connecting beam, and the spacing between two adjacent stop bolts gradually decreases.

[0014] As a further description of the above technical solution:

[0015] The center of gravity of the drilling assembly is located between the stop bolt and the auxiliary part of the connecting beam.

[0016] As a further description of the above technical solution:

[0017] The drilling assembly includes:

[0018] A fixed bracket is fixedly connected to a connecting crossbeam, and the fixed bracket is a hollow frame structure;

[0019] The motor is fixedly installed inside the fixed bracket, and an impact drill bit is fixedly installed at the output end of the motor. Fixed handles are fixedly installed on both sides of the motor.

[0020] The fixed bracket is fixedly installed with a threaded cover plate and a shaft cover plate on both sides along the direction of the motor shaft. The shaft cover plate has a through hole corresponding to the motor shaft.

[0021] As a further description of the above technical solution:

[0022] A bearing is fixedly installed inside the through hole on the shaft cover plate, and the motor shaft is fixedly connected to the inner ring of the bearing.

[0023] As a further description of the above technical solution:

[0024] A power cord is provided at the tail of the motor.

[0025] The beneficial effects of this utility model are:

[0026] This invention, through the design of a pull rope component and a connecting beam, allows the user to support the drilling assembly by using the pull rope component in conjunction with the auxiliary part of the connecting beam supported by the user's shoulders during drilling. The user operates the fixed handle with both hands to position and drill the hole. Compared to the traditional method where the user's hands bear the weight of the drilling assembly, this method provides more stable force for manipulating the drilling assembly, resulting in better hole quality. Furthermore, it requires less physical strength from the operator (shoulder strength is easier than hand strength). The stable drilling operation also reduces the risk of drill bit deformation and breakage. Attached Figure Description

[0033] Please refer to the attached document. Figures 1-3 This application illustrates a drilling device for photovoltaic brackets, which is used for drilling photovoltaic brackets during photovoltaic installation. It is mainly suitable for drilling vertical brackets and specifically includes: a drilling assembly, a connecting beam 3, and a rope component 1.

[0034] Fixed handles 6 are fixedly installed on both the left and right sides of the drilling assembly. The fixed handles 6 are used to operate the drilling assembly to perform drilling operations. The connecting beam 3 is fixedly connected to the side of the drilling assembly, and the length direction of the connecting beam 3 is along the length direction of the impact drill bit 5 of the drilling assembly. The end of the connecting beam 3 away from the impact drill bit 5 of the drilling assembly is extended to form an auxiliary part. The top of the connecting beam 3 is fixedly connected to the stop bolt 2. One end of the pull rope 1 is hooked to the stop bolt 2, and the other end of the pull rope 1 is hooked to the photovoltaic bracket.

[0035] like Figure 1 As shown, the pull rope 1, the drilling assembly, and the connecting beam 3 form a right-angled triangle structure with the vertical support. At this time, the pull rope 1 pulls the drilling assembly and the connecting beam 3 diagonally upwards, and with the user's shoulder supporting the auxiliary part of the connecting beam 3, the two forces can balance the weight of the drilling assembly (basically balanced). At this time, the user manually operates the fixed handle 6 to stabilize the impact drill bit 5 of the drilling assembly (in the process of stabilizing the impact drill bit 5 of the drilling assembly, a large stabilizing force is required in the early stage, otherwise the impact drill bit 5 is easy to slide on the surface of the vertical support. After the initial hole is formed, the requirement for stabilizing force is not high), so that it can stably drill holes on the vertical support. During the drilling process, the drilling assembly and the connecting beam 3 move laterally, the connecting beam 3 slides on the user's shoulder / the user's body moves forward in coordination, the pulling force provided by the pull rope 1 decreases, and the user provides part of the vertical support force for the drilling assembly through the fixed handle 6.

[0036] In one embodiment, the pull rope component 1 includes: a rigid rope 101 and an elastic rope 102 arranged in parallel. The first end of the rigid rope 101 and the first end of the elastic rope 102 are connected to a first hook 103. The second end of the rigid rope 101 and the second end of the elastic rope 102 are connected to a second hook 104. The first hook 103 is connected to the top of the vertical bracket, and the second hook 104 is connected to the stop bolt. For example, the second hook 104 can be a ring hook (which cooperates with the stop bolt 2) or an arc hook (which cooperates with the fixing ring on the stop bolt 2). The first hook 103 can be a pin that can be inserted into the top of the hollow vertical bracket. The length of the elastic rope 102 in its natural state is less than the length of the rigid rope 101.

[0037] like Figure 1 In the state shown, the rigid rope 101 is in a taut state and the elastic rope 102 is in an elastically stretched state. Due to the restriction of the rigid rope 101, the rope member 1 cannot be stretched as a whole. During the drilling process of the drilling assembly and the connecting beam 3, the rope member 1 is relaxed, that is, the rigid rope 101 is in a relaxed state, the elastic tension provided by the elastic rope 102 is reduced, and the user provides part of the vertical support force for the drilling assembly by fixing the handle 6.

[0038] In one embodiment, a plurality of stop bolts 2 are provided along the length of the connecting beam 3. Among the plurality of stop bolts 2, the spacing between two adjacent stop bolts 2 gradually decreases, such as... Figure 3 As shown, the user can interchange the connection between the pull rope component 1 and the multiple stop bolts 2, thereby achieving the purpose of drilling a vertically distributed row of holes on the same vertical bracket. To ensure that the hole spacing is all of length L, it can be done according to... Figure 3 The distribution of multiple stop bolts 2 is designed in the manner described in the text.

[0039] When switching between different bolt positions 2 to drill holes, the user can use a semi-squatting posture to control the height of the shoulder, thereby ensuring that the connecting beam 3 is basically in a horizontal state.

[0040] In one embodiment, the center of gravity of the drilling assembly is located between the stop bolt 2 and the auxiliary part of the connecting beam 3. This design can avoid the problem of tilting torque caused by an unstable center of gravity of the drilling assembly, which makes it inconvenient for the user to operate.

[0041] In one embodiment, the drilling assembly includes: a fixed bracket 4, a motor 7, a threaded cover plate 9, and a shaft cover plate 10.

[0042] The fixed bracket 4 is fixedly connected to the connecting beam 3. The fixed bracket 4 is a hollow frame structure, generally made of 12 square tubes welded together. The motor 7 is fixedly installed on the inner side of the fixed bracket 4. The output end of the motor 7 is fixedly installed with an impact drill bit 5. The motor 7 drives the impact drill bit 5 to rotate. Generally, the output end of the motor 7 is fixedly installed with a quick connector (a universal drill quick connector). The impact drill bit 5 is installed on the quick connector. Fixed handles 6 are fixedly installed on both sides of the motor 7. Threaded cover plates 9 and shaft cover plates 10 are fixedly installed on both sides of the fixed bracket 4 along the rotation axis of the motor 7. The shaft cover plate 10 has through holes corresponding to the rotation axis of the motor 7.

[0043] In one embodiment, in order to improve the stability of the motor 7's shaft, a bearing is fixedly installed inside the through hole on the shaft cover plate 10, and the motor 7's shaft is fixedly connected to the inner ring of the bearing.

[0044] In one embodiment, a power cord 8 is provided at the tail of the motor 7. The power cord 8 is designed to face backward so as not to interfere with the drilling operation.
