Description

Technical Field

[0001] This utility model belongs to the field of hanging point technology, and in particular relates to a safety belt hanging point clamping device for edge operations in the operation and maintenance and construction of photovoltaic modules. Background Technology

[0002] During the construction of photovoltaic power generation and charging stations, as well as the daily operation and maintenance of photovoltaic systems, near-edge work occurs frequently. These work areas often lack stable anchor points for safety belts, posing a significant risk of falls to workers at height. When the work area has steel structural support, the usual practice is to rely on safety belts being knotted around the steel structure or using strong ropes wrapped around it as anchor points to ensure personnel safety. However, in locations such as the edges of rooftops where there is insufficient space or structure for knotting, the serious problem of lacking reliable anchor points for safety belts arises.

[0003] Therefore, it is essential to invent a safety belt hanging point clamping device for edge operations in the operation, maintenance and construction of photovoltaic modules. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a safety belt hanging point clamping device for edge operations in photovoltaic module operation and maintenance and construction, comprising a spiral shaft housing, a bearing, a hanging point clamping mechanism, a bearing sleeve, a handle plate, a carrying port, and a rope hanging hole. The spiral shaft of the hanging point clamping mechanism is rotatably mounted inside the spiral shaft housing via a bearing, and the bearing sleeve is rotatably mounted on the outside of the spiral shaft housing via a bearing. A handle plate is fixedly mounted on the outside of the bearing sleeve, with a carrying port through the middle of the handle plate and rope hanging holes through both ends.

[0005] Preferably, the hanging point clamping mechanism further includes a spiral sleeve, a clamping arm, and a clamping arm head. Two spiral sleeves are mirror-symmetrically installed on the spiral shaft. Each spiral sleeve is fixedly installed with a clamping arm. The clamping arm protrudes through a groove through the spiral shaft housing. A clamping arm head is fixedly installed at one end of the clamping arm protruding through the groove.

[0006] Preferably, each of the clamping arm heads is fixedly fitted with an anti-slip pad by bolts.

[0007] Preferably, the helical shaft is provided with two sections of threads with opposite directions of rotation, namely a left-handed helix and a right-handed helix, and two mirror-symmetrically arranged helical sleeves are installed on the helix that matches the helical shaft.

[0008] Preferably, bearing caps are fixedly installed at both ends of the spiral shaft housing, and two bearing caps are provided in total.

[0009] Preferably, both ends of the spiral shaft rotate through the bearing cover and protrude outwards.

[0010] Preferably, a hexagonal head and a knob are fixedly installed at both ends of the protruding spiral shaft, and the hexagonal head and the knob are located outside the bearing cover.

[0011] Preferably, the handle plate has a through-hole for carrying between the two hook holes, and each handle is equipped with a reliable safety belt hook.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention effectively solves the problem of missing safety belt attachment points during edge work through an innovative design of the spiral shaft housing, bearing, and attachment point clamping mechanism. The bearing sleeve design is particularly crucial; it rotates under lateral tension from the attachment rope, effectively dispersing and reducing the lateral tension on the spiral shaft housing body, thereby improving the device's durability and service life. Simultaneously, this design enhances the device's stability, avoiding the risk of tilting or overturning due to uneven force distribution, providing a safer and more reliable working environment for personnel.

[0014] This utility model is not only compact, durable, and reliable, but also easy to operate and carry. The design of the handle plate, carrying port, and lanyard hole allows operators to easily operate and carry the device with one hand, improving work efficiency. Meanwhile, the clamping mechanism employs a spiral sleeve, clamping arms, and clamping arm heads. The clamping arms open and close by rotating the spiral shaft, and the anti-slip pads on the clamping arm heads further enhance the clamping force, ensuring the device can be firmly fixed to various steel structures or similar supports, demonstrating strong adaptability and a wide range of applications. Furthermore, the bidirectional spiral design makes the clamping force more balanced, further improving the stability and safety of the device and providing operators with a superior working experience.

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides a safety belt hanging point clamping device for edge operations in the operation and maintenance and construction of photovoltaic modules, including a spiral shaft housing 1, a bearing 2, a hanging point clamping mechanism 3, a bearing sleeve 4, a handle plate 5, a carrying port 6, and a rope hanging hole 7. The spiral shaft housing 1 is rotatably mounted with the spiral shaft 31 of the hanging point clamping mechanism 3 through the bearing 2 inside. The bearing sleeve 4 is rotatably mounted with the bearing 2 in the middle of the outer side of the spiral shaft housing 1. The handle plate 5 is fixedly mounted on the outer side of the bearing sleeve 4. The carrying port 6 is opened through the middle of the handle plate 5, and the rope hanging hole 7 is opened through both ends of the handle plate 5.

[0024] Furthermore, the hanging point clamping mechanism 3 also includes a spiral sleeve 32, a clamping arm 33, and a clamping arm head 34. Two spiral sleeves 32 are mounted mirror-symmetrically on the spiral shaft 31, a design that ensures a balanced distribution of clamping force. Each spiral sleeve 32 is fixed with a clamping arm 33, which extends outward through a groove in the spiral shaft housing 1. The extended end of the clamping arm 33 is fixed with a clamping arm head 34 for close contact with the support and to provide a stable clamping effect.

[0025] Furthermore, to further enhance the stability of the clamping mechanism, anti-slip pads 9 are bolted to each clamping arm head 34. This anti-slip pad design not only increases the friction between the clamping mechanism and the support, but also ensures that the device maintains a stable clamping state even in harsh operating environments.

[0026] Furthermore, the helical shaft 31 is provided with two sections of threads with opposite directions of rotation, namely a left-handed helix and a right-handed helix. This design allows two mirror-symmetrical helical sleeves 32 to be installed on their respective matching helices. When the helical shaft 31 rotates, the two helical sleeves 32 move synchronously and in opposite directions, thereby driving the clamping arms 33 and clamping arm heads 34 to open and close.

[0027] Furthermore, bearing covers 8 are fixedly installed at both ends of the spiral shaft housing 1. These bearing covers not only protect the spiral shaft 31 but also ensure that the spiral shaft can rotate smoothly. Both ends of the spiral shaft 31 pass through the bearing covers 8 and protrude outwards. This design allows operators to easily operate the spiral shaft to adjust the clamping mechanism.

[0028] Furthermore, a hexagonal head 35 and a knob 36 are fixedly mounted at both ends of the protruding spiral shaft 31. The hexagonal head 35 allows operators to rotate the spiral shaft 31 using tools such as wrenches, while the knob 36 provides convenient manual adjustment. This design not only improves work efficiency but also makes the device more flexible to operate.

[0029] Furthermore, a carrying port 6 is provided through the handle plate 5 between two lanyard holes 7, a design that allows operators to easily carry and move the device. At the same time, each carrying port 6 is equipped with a reliable safety harness hook, a design that ensures the safety harness can be securely attached to the device, providing additional safety for the operator.

[0030] The working principle is as follows: First, when the safety belt attachment point clamping device for edge operations in the operation and maintenance and construction of this photovoltaic module needs to be used, the operator will carry and move the device to the work site through the handle 6 and the rope hanging hole 7. The design of the handle 6 makes the device easy to lift and put down, while the rope hanging hole 7 allows the operator to hang the device on their body or other fixed points for easy access.

[0031] Then, the operator selects a suitable support according to the operational requirements and places the device on the support. At this time, the hanging point clamping mechanism 3 begins to function. The operator rotates the hexagonal head 35 using a hex wrench, or drives the rotation of the screw shaft 31 by hand using the knob 36. Since the screw shaft 31 has two sections of threads with opposite directions of rotation (left-hand and right-hand threads), when the screw shaft 31 rotates, the two mirror-symmetrical screw sleeves 32 will move synchronously and in opposite directions.

[0032] Next, as the spiral sleeve 32 moves, the clamping arms 33 fixed to it also move accordingly. The clamping arm heads 34, fixed at the extended ends of the two clamping arms 33, gradually approach the support until the anti-slip pads 9 on the clamping arm heads 34 are in close contact with the support, providing a stable clamping effect. In addition, by rotating the spiral shaft 31 in different directions, the operator can adjust the degree of closure of the clamping arms 33 and clamping arm heads 34 until they are firmly clamped to the support.

[0033] During the clamping process, the bearing sleeve 4 and bearing 2 play a crucial role. They allow relative rotation between the helical shaft housing 1 and the helical shaft 31, thereby ensuring the flexibility and stability of the clamping mechanism. At the same time, the bearing cover 8 protects the end of the helical shaft 31, preventing the ingress of dust and debris and extending the service life of the device.

[0034] Finally, once the device is securely clamped to the support, the operator can attach their safety belt to the safety belt hook on the carrying port 6. This provides additional safety for the operator, even when working at height. By adjusting the rotation of the screw shaft 31, the operator can also adjust the clamping force and position of the device at any time to adapt to different working environments and needs.

[0035] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
