Description

Technical Field

[0001] This utility model relates to the field of fastening tool technology, and in particular to a quick fastening tool for mounting bolts of photovoltaic flexible support components. Background Technology

[0002] Currently, because photovoltaic modules in flexible photovoltaic support systems are generally installed at a high position above the ground, often beyond the reach of workers, it is difficult for workers to tighten the mounting bolts and nuts on the photovoltaic modules without the aid of other tools.

[0003] To address the aforementioned technical issues, existing bolt tightening methods primarily rely on installation platforms where workers operate wrenches. However, this method has numerous drawbacks. The most obvious is the long assembly and disassembly time required. Furthermore, the large size and dispersed location of bolts mean that frequent movement can disrupt the workflow. While elevators or aerial work platforms can be used, equipment scheduling requires coordination. In some photovoltaic power plants with complex terrain, limited construction space and inconvenient worker operation further increase the difficulty and time cost of bolt tightening, resulting in low bolt tightening efficiency.

[0004] Therefore, developing an auxiliary tool that can quickly, efficiently, and accurately tighten various types of bolts is of great significance for improving the construction efficiency and quality of photovoltaic power plants. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a quick-tightening tool for photovoltaic flexible support component mounting bolts, so as to solve the technical problem of low efficiency in the tightening of existing photovoltaic flexible support component mounting bolts.

[0006] To achieve the above objectives, this utility model provides a quick-tightening fixture for mounting bolts of photovoltaic flexible support components, used for fastening mounting bolts and nuts of components at high locations, comprising:

[0007] Torque transmission rod;

[0008] A nut sleeve is provided at one end of the torque transmission rod, and a screwing groove adapted to the shape of the nut is formed on the nut sleeve;

[0009] Support rod;

[0010] A bolt sleeve is provided at one end of the support rod. The bolt sleeve has a positioning groove that matches the shape of the bolt head of the component mounting bolt. When tightening, the bolt sleeve is fitted onto the surface of the bolt head to restrict the axial rotation of the component mounting bolt. The nut sleeve is connected to the nut, and a driving force is applied to the torque transmission rod to generate torque, thereby driving the nut sleeve to tighten the nut.

[0011] As a preferred embodiment of this utility model, the torque transmission rod is provided with a wrench sleeve at its other end relative to the nut sleeve, and the wrench sleeve has an interface at its bottom end that is adapted to the output end of the electric wrench.

[0012] As a preferred embodiment of this utility model, the torque transmission rod is provided with a first connector and a second connector at its top and bottom ends, respectively. The first connector engages with a first connecting groove at the bottom end of the nut sleeve, and the second connector engages with a second connecting groove at the top end of the wrench sleeve.

[0013] As a preferred embodiment of this utility model, both the first connector and the second connector are polygonal prisms. Correspondingly, the first connecting groove and the second connecting groove are polygonal prism grooves. Through the insertion and extraction of the polygonal groove and the polygonal prism, rotation between the nut sleeve and the wrench sleeve relative to the torque transmission rod is prevented.

[0014] As a preferred embodiment of this utility model, the support rod includes an upright and a connecting rod with one end connected to the top of the upright, and the upright is fixedly connected to the bolt sleeve.

[0015] As a preferred embodiment of this utility model, the upright and the connecting rod are perpendicular to each other.

[0016] As a preferred embodiment of this utility model, a stop structure is provided in the positioning groove of the bolt sleeve. The stop structure is used to abut against the bolt head to prevent the bolt from rising or falling during the tightening process.

[0017] As a preferred embodiment of this utility model, the stop structure is a baffle plate disposed in the positioning groove of the bolt sleeve.

[0018] As a preferred technical solution of this utility model, the tooling further includes a hollow tube with an internal hollow structure and open ends. The torque transmission rod is sleeved in the hollow tube so that the torque transmission rod can be raised, lowered, and rotated relative to the hollow tube. The hollow tube is fixedly connected to the support rod, and the centerlines of the bolt sleeve and the nut sleeve coincide with each other.

[0019] As a preferred embodiment of this utility model, the hollow tube is provided with a connecting rod on its outer circumference, and one end of the connecting rod is fixedly connected to the support rod.

[0020] The beneficial effects of this utility model are as follows: By setting up a torque transmission rod and a nut sleeve, the worker can hold the torque transmission rod and connect the nut sleeve to the nut at a high position. Applying a driving force to the torque transmission rod generates torque, which drives the nut sleeve to tighten the nut. At the same time, a support rod and a bolt sleeve are set up. When the bolt sleeve is fitted on the surface of the bolt head, it can restrict the axial rotation of the component mounting bolt, ensuring that the component mounting bolt does not rotate synchronously when tightening the nut, thus guaranteeing the tightening effect. The component mounting bolt at a high position can be tightened without raising the working surface, which greatly improves the tightening efficiency. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0029] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0030] like Figure 1 As shown, a quick-tightening fixture for mounting bolts of photovoltaic flexible support components is used to tighten bolts and nuts at high positions. It includes: a torque transmission rod 1; a nut sleeve 4, which is located at one end of the torque transmission rod 1, and has a turning groove 5 that matches the shape of the nut; a support rod; and a bolt sleeve 12, which is located at one end of the support rod, and has a positioning groove that matches the shape of the bolt head of the component mounting bolt. When tightening, the bolt sleeve 12 is fitted onto the surface of the bolt head to restrict the axial rotation of the component mounting bolt. The nut sleeve 4 is connected to the nut, and a driving force is applied to the torque transmission rod 1 to generate torque, which drives the nut sleeve 4 to tighten the nut.

[0031] The above technical solution uses the original ground as the working surface, eliminating the need to raise the working surface to form a point-to-surface operating surface corresponding to each bolt. Workers can stand on the original ground and adjust the fastening fixture to the position of the corresponding component mounting bolt, then use the fastening fixture to tighten the component mounting bolt. The specific operating steps are as follows: During use, the worker holds the torque transmission rod 1 in one hand and the support rod in the other. The support rod is operated so that the bolt sleeve 12 at one end is fitted onto the bolt head of the component mounting bolt. Then, the torque transmission rod 1 is operated so that the turning groove 5 of the nut sleeve 4 at one end is aligned with and inserted into the nut. When tightening the nut, simply rotate the torque transmission rod 1 to rotate the nut sleeve 4, thereby rotating the nut. The support rod and bolt sleeve 12 remain separate, thus restricting the rotation of the component mounting bolt through the bolt sleeve 12, preventing the component mounting bolt from rotating with the nut during tightening, which would prevent the component mounting bolt and nut from being unable to be tightened.

[0032] like Figure 1As shown, in this embodiment, the torque transmission rod 1 is provided with a wrench sleeve 7 at its other end relative to the nut sleeve 4, and the wrench sleeve 7 has an interface 8 at its bottom end that is adapted to the output end of the electric wrench.

[0033] The above technical solution can further improve the efficiency of tightening nuts. By inserting the output end of the electric wrench into the interface 8 at the bottom of the wrench sleeve 7, when the output end of the electric wrench rotates, it will drive the wrench sleeve 7 to rotate synchronously, thereby causing the wrench sleeve 7 to drive the torque transmission rod 1 to rotate synchronously. The torque transmission rod 1 drives the nut sleeve 4 to tighten the nut. Compared with manually tightening the torque transmission rod 1, the efficiency is significantly improved. The nut sleeve 4 is a national standard part.

[0034] like Figure 2 and Figure 3 As shown, in this embodiment, the torque transmission rod 1 is provided with a first connector 2 and a second connector 3 at its top and bottom ends, respectively. The first connector 2 engages with the first connecting groove 6 at the bottom end of the nut sleeve 4, and the second connector 3 engages with the second connecting groove 9 at the top end of the wrench sleeve 7. Preferably, the first connector 2 and the second connector 3 are both polygonal prisms, and correspondingly, the first connecting groove 6 and the second connecting groove 9 are polygonal prism grooves. The insertion and extraction of the polygonal grooves and the polygonal prisms prevents the nut sleeve 4 and the wrench sleeve 7 from rotating relative to the torque transmission rod 1.

[0035] The above technical solution allows for easy replacement of the nut sleeve 4 and the wrench sleeve 7 to accommodate nuts and electric wrenches of different specifications. Taking the nut sleeve 4 as an example, when the nut sleeve 4 needs to be replaced, a force is applied to the nut sleeve 4 in the axial direction away from the first connector 2, causing the nut sleeve 4 to overcome resistance until the first connecting groove 6 inside it is disengaged from the first connector 2, thus completing the disassembly. The first connecting groove 6 of the required nut sleeve 4 is then inserted into the first connector 2 to complete the replacement.

[0036] like Figure 2 and Figure 3 As shown, in this embodiment, the support rod includes a vertical rod 10 and a connecting rod 11 with one end connected to the top of the vertical rod 10. The vertical rod 10 is fixedly connected to the bolt sleeve 12. Preferably, the vertical rod 10 and the connecting rod 11 are perpendicular to each other.

[0037] The above technical solution ensures that the bolt sleeve 12 and the nut sleeve 4 can be coaxial when tightening bolts and nuts. By arranging the upright 10 and the torque transmission rod 1 in parallel and at intervals, it can be ensured that the nut sleeve 4 is connected to the nut, while the bolt sleeve 12 is connected to the bolt head.

[0038] Furthermore, in order to better tighten the bolts and nuts, in this embodiment, a stop structure is provided in the positioning groove of the bolt sleeve 12; the stop structure is a baffle provided in the positioning groove of the bolt sleeve 12, which is not shown in the figure.

[0039] The above technical solution can improve the stability of bolts and nuts during tightening. Since the torque transmission rod 1 applies an upward force to the nut from bottom to top, a baffle is provided to prevent the bolt from swaying up and down with this force. The baffle is used to abut against the bolt head to prevent the bolt from rising and falling during tightening.

[0040] like Figure 4 and Figure 5 As shown, in this embodiment, the tooling also includes a hollow tube 13 with an internal hollow structure and open ends. The torque transmission rod 1 is sleeved in the hollow tube 13 so that the torque transmission rod 1 can be raised, lowered, and rotated relative to the hollow tube 13. The hollow tube 13 is fixedly connected to the support rod, and the center lines of the bolt sleeve 12 and the nut sleeve 4 coincide with each other. A connecting rod 14 is provided on the outer circumference of the hollow tube 13. One end of the connecting rod 14 is fixedly connected to the support rod. Specifically, the connecting rod 14 is fixed to the lower end of the upright 10 of the support rod.

[0041] The above technical solution can further improve the fastening efficiency of bolts and nuts. In practice, it has been found that when the bolts and nuts are high off the ground, especially when the bolt head is above the photovoltaic module, they will be blocked, making it difficult to observe the position. Only the approximate position can be inferred from the nut. In this case, it is quite challenging for workers to align the two completely separate nut sleeves 4 and bolt sleeves 12 with the bolt head and nut respectively.

[0042] To improve this situation, the torque transmission rod 1 and the connecting rod 11 are integrated, so that the nut sleeve 4 and the bolt sleeve 12 are coaxial. When the nut sleeve 4 is aligned with the nut, the bolt sleeve 12 is also located on the extension line of the bolt head's axis, eliminating the need for separate positioning. Then, the hollow tube 13 is pulled down to drive the connecting rod 14, the upright rod 10, the connecting rod 11, and the bolt sleeve 12. The bolt sleeve 12 is used to press down and position the bolt head. Then, the torque transmission rod 1 is pushed up to rise relative to the hollow tube 13 until the nut sleeve 4 at the upper end of the torque transmission rod 1 contacts the nut. The output end of the electric wrench is inserted into the interface 8 of the wrench sleeve 7, and the electric wrench is started to rotate the output end, which in turn rotates the wrench sleeve 7. The wrench sleeve 7 rotates the torque transmission rod 1, and the torque transmission rod 1 rotates the nut through the nut sleeve 4, thereby tightening the bolt and nut.

[0043] The relevant process parameters for this fixture are as follows:

[0044] 1. The electric wrench and the wrench sleeve 7 on the torque transmission rod 1, the wrench sleeve 7 is a national standard electric wrench sleeve, the sleeve diameter is ≤ the diameter of the required fastening bolt;

[0045] 2. The connection nodes of the torque transmission rod 1, the first connector 2, and the second connector 3 are either welded together or integrally formed using mold castings;

[0046] 3. Corresponding to the second connector 3, the diameter of the hexagonal head of the second connector 3 is equal to the inner diameter of the second connecting groove 9 in the wrench sleeve 7, and the length of the hexagonal head is greater than or equal to the inner depth of the second connecting groove 9; the diameter of the torque transmission rod 1 is less than or equal to the diameter of the hexagonal head of the required fastening bolt, and the length of the torque transmission rod 1 is equal to the height of the fastening bolt from the ground - the height of the operator + 500mm; the first connector 2 is a square head, the diameter of the square head is equal to the inner diameter of the first connecting groove 6 in the nut sleeve 4, and the length of the square head is greater than or equal to the inner depth of the first connecting groove 6;

[0047] 4. The support rod consists of two parts: the upright 10 and the connecting rod 11. The connection between the two parts is made by welding or casting a single piece using a mold, or by bending a single pipe with a bending angle of 90 degrees. The diameter of the support rod is less than or equal to the diameter of the hexagonal head of the required fastening bolt. The bolt sleeve 12 has an inner diameter of the positioning groove equal to the diameter of the hexagonal head of the required fastening bolt, and an inner depth of the sleeve greater than or equal to the thickness of the hexagonal head of the required fastening bolt.

[0048] Working principle: In use, the worker holds the torque transmission rod 1 in one hand and the upright rod 10 in the other. The upright rod 10 is operated so that the connecting rod 11 fits the bolt sleeve 12 onto the bolt head of the component mounting bolt. Then, the torque transmission rod 1 is operated so that the turning groove 5 of the nut sleeve 4 at one end is aligned with the nut and inserted. When turning the nut, only the torque transmission rod 1 needs to be rotated to drive the nut sleeve 4 to rotate, thereby driving the nut to rotate. The upright rod 10, the connecting rod 11, and the bolt sleeve 12 remain at different positions, thereby restricting the rotation of the component mounting bolt through the bolt sleeve 12. This prevents the component mounting bolt from rotating with the nut during the turning process, which would cause the component mounting bolt and nut to be unable to be tightened. Thus, the component mounting bolt can be tightened using fastening fixtures without raising the working surface, which greatly improves the tightening efficiency of the component mounting bolt.
