These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] Many pieces of equipment are currently installed at high locations, such as the cooling fans of wind turbine generators. When these high-altitude devices are damaged, disassembling and replacing them manually is an extremely time-consuming and labor-intensive task, and may result in falling objects, posing a serious safety risk.

[0048] In existing technologies, the aforementioned problems are generally solved by fixing and installing lifting auxiliary devices such as pulleys to hoist high-altitude equipment. However, existing high-altitude equipment hoisting auxiliary devices require drilling bolt holes or anchor bolts in the crossbars, and then fastening the hoisting auxiliary devices to the crossbars with bolts or anchor rods. Due to the height of the crossbars, existing hoisting auxiliary devices are difficult to install, causing inconvenience for the disassembly and replacement of high-altitude equipment.

[0049] I-beams, due to their strong load-bearing capacity, are widely used as load-bearing components in high-altitude applications; for example, the crossbars of wind turbine towers are made of I-beams. In light of this widespread use, the technical concept of this application is as follows: a pair of lugs, with a pulley sandwiched between them; a fixing plate mounted above each lug, with a gap between the fixing plates, allowing the fixing plates to slide along the flanges of the I-beam. Fastening components are provided on the lugs or fixing plates to secure them to the web of the I-beam.

[0050] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0051] In one possible embodiment of this application, a hoisting auxiliary device is provided. Figure 1 This is a side view of a hoisting auxiliary device provided in an embodiment of this application, such as... Figure 1 As shown, the hoisting auxiliary device is used to install on the I-beam 700 and includes a lug plate 100, a fixing plate 300, and a pulley 200.

[0052] Two ear plates 100 are symmetrically arranged, and at least two fixing plates 300 are arranged. The at least two fixing plates 300 are respectively symmetrically arranged above the opposite side of the two ear plates 100, and there is a gap between the two opposite fixing plates 300. When the two opposite fixing plates 300 abut against the flange 710 on the I-beam 700, the web plate 720 on the I-beam 700 is located within the gap.

[0053] The distance between the fixed plates 300 can be determined based on the cross-sectional width of the web 720 of the I-beam 700 to ensure that the fixed plates 300 can be pushed into the I-beam 700.

[0054] like Figure 1 As shown, in actual use, the gap between the fixed plates 300 installed in the ear plates 100 can be aligned with the web plate 720 of the I-beam 700, the hoisting auxiliary device can be pushed into the flange plate 710 of the I-beam 700, and the hoisting auxiliary device can be pushed to the required position.

[0055] The pulley 200 is installed between the two ear plates 100 and is located below the fixed plate 300, so that when the fixed plate 300 abuts against the flange 710 on the I-beam 700, the pulley 200 is located below the I-beam 700. Optionally, multiple pulleys 200 can be installed between the two ear plates 100, so that multiple aerial devices can be lifted at the same time.

[0056] A fastening assembly is disposed on at least one of the ear plate 100 and the fixing plate 300, and the fastening assembly is configured to secure at least one of the ear plate 100 and the fixing plate 300 to the web plate 720 of the I-beam 700.

[0057] Specifically, in actual use, after the hoisting auxiliary device is pushed to the required position according to the above steps, the fixed plate 300 is engaged with the wing plate 710 below, and the fixed plate 300 clamps the web plate 720, forming a relatively stable clamping structure. Therefore, the fastening components can improve the stability of the hoisting auxiliary device on the I-beam 700 by clamping. Then, by passing the chain hoist through the pulley 200 below, the hoisting work of the high-altitude equipment can be completed. It can be seen that the hoisting auxiliary device provided in this embodiment has the advantages of convenient and quick installation and good stability.

[0058] like Figure 1As shown, the fixed disk 300 has a connecting shaft 320, which is fixed to the fixed disk 300. Optionally, the ear plate 100 has a connecting hole, and the fixed disk 300 is rotatably connected to the ear plate 100 via the connecting shaft 320 and the connecting hole. When the fixed disk 300 is rotatable, it can be more easily pushed to the desired position on the wing plate 710.

[0059] In one possible embodiment of this application, another hoisting auxiliary device is provided. Figure 2 This is a front view of another hoisting auxiliary device provided in the embodiments of this application, such as... Figure 2 As shown, each ear plate 100 is provided with at least two fixed plates 300. When multiple fixed plates 300 slide on the wing plate 710, the stability is better than when a single fixed plate 300 slides on the wing plate 710, thereby further improving the stability of the hoisting auxiliary device on the I-beam 700 and reducing the risk of falling from a height.

[0060] In this embodiment, the fastening assembly includes at least two fasteners, each fastener being correspondingly provided with the fixing plate 300. The fasteners are configured to fasten the fixing plate 300 to the I-beam 700.

[0061] Optionally, the fastener is a fastening bolt. Figure 3 This is a side view of another hoisting auxiliary device provided in an embodiment of this application, such as... Figure 3 As shown, the fixed plate 300 has a through hole 310, and the fastening bolt threaded through the through hole 310. The fastening bolt fastens the fixed plate 300 to the I-beam 700 through the through hole 310.

[0062] It should be noted that, since the fixing discs 300 symmetrically arranged on both sides of the ear plate 100 are provided with through holes 310, after the fastening bolts are driven into the through holes 310, the fastening bolts on both sides of the web plate 720 clamp the middle web plate 720. In addition, since each ear plate 100 is provided with at least two fixing discs 300, and two fastening bolts are driven into each ear plate 100, the clamping stability is good.

[0063] like Figure 2 As shown, since the connecting shaft 320 is fixed to the fixed plate 300, and the hoisting auxiliary device is clamped and fastened by the fastening bolts on both sides of the web plate 720, the through hole 310 can be set on the connecting shaft 320. When the fixed plate 300 can rotate, since the connecting shaft 320 is the axis of rotation, setting the through hole 310 on the connecting shaft 320 can keep the position of the through hole 310 fixed, thereby facilitating the installation of the fastening bolts.

[0064] In one possible embodiment of this application, yet another hoisting auxiliary device is provided. Figure 4 This is a front view of another hoisting auxiliary device provided in this application, such as... Figure 4As shown, the ear plate 100 has at least one auxiliary through hole 120, and at least two auxiliary through holes 120 are symmetrically arranged below the two ear plates 100 respectively.

[0065] The purpose of setting an auxiliary through hole 120 below the ear plate 100 is to allow ropes to pass through the auxiliary through hole 120 and pull the hoisting auxiliary device to a suitable position on the I-beam 700, considering that it is not convenient to directly push the hoisting auxiliary device in a confined space.

[0066] like Figure 4 As shown, the fastening assembly also includes auxiliary fasteners, which include a connecting plate 400, an abutment block 500, and a connecting screw 510 connected to the abutment block 500. The connecting plate 400 is connected to the ear plate 100, the connecting screw 510 passes through the connecting plate 400, and the abutment block 500 is configured such that tightening the nut on the connecting screw 510 moves the abutment block 500 toward or away from the web 720 of the I-beam 700.

[0067] Figure 5 This is a schematic diagram of an auxiliary fastening component provided in an embodiment of this application, such as... Figure 5 As shown, the connecting plate 400 has a fixing through hole 410 with its axis perpendicular to the inner side; the abutting block 500 has a connecting screw 510 on one side.

[0068] In practical applications, while the fixed plate 300 alone can secure the hoisting auxiliary device, considering its primary use in high-altitude operations, additional auxiliary fasteners are installed outside the fixed plate 300 to improve its stability on the I-beam 700. For example... Figure 4 As shown, the auxiliary clamping device is located on the side of the ear plate 100 where the mounting plate 300 is installed, thereby serving to clamp the I-beam 700 together with the mounting plate 300.

[0069] Figure 6 This is a side view of another hoisting auxiliary device provided in the embodiments of this application, such as... Figure 6 As shown, the abutment blocks 500 on both sides abut against the web plate 720, the connecting screw 510 passes through the connecting plate 400, and the exposed part of the connecting screw 510 outside the connecting plate 400 is fitted with a nut.

[0070] Specifically, in practical application, firstly, align the gap between the fixing plates 300 installed in the ear plates 100 with the web plate 720 of the I-beam 700. Push the lifting auxiliary device into the flange plate 710 of the I-beam 700 and move it to the required position. Then, drive in the fastening bolts through the through holes 310. Since fastening bolts are driven into the through holes 310 on both sides, the paired fastening bolts can clamp the middle I-beam 700, thus completing the initial fixation of the lifting auxiliary device on the I-beam 700. Next, pass the connecting bolt 510 through the fixing through hole 410, put the nut on the connecting bolt 510, and tighten the nut to make the abutment block 500 abut against the web plate 720.

[0071] The technical effect of this embodiment is:

[0072] Since each ear plate 100 is equipped with an auxiliary fastener, the abutment block 500 can clamp the middle I-beam 700, thereby providing additional clamping force in addition to the bolts on the fixing plate 300, improving the stability of the hoisting auxiliary device on the I-beam 700 and preventing it from falling from a height.

[0073] In one possible embodiment of this application, another auxiliary fastener is provided. Figure 7 This is a schematic diagram of another auxiliary fastener provided in an embodiment of this application, such as... Figure 7 As shown, the connecting plate 400 has a plurality of fixing through holes 410 through which the connecting screws 510 pass, and each fixing through hole 410 is spaced apart along the height direction of the connecting plate 400.

[0074] In practical use, due to the complex environment at high altitudes, there may be other objects near the I-beam 700. In this case, it may be necessary to adjust the height of the hoisting auxiliary device to avoid interference between the pulleys below and other objects. Multiple fixing through holes 410 are provided along the height direction on the connecting plate 400. The connecting bolt 510 can be selected to pass through which fixing through hole 410 as needed. After tightening the abutment block 500, the web plate 720 is clamped between the abutment block 500 and the abutment block 500. This allows for adjustment of the hoisting auxiliary device's height within a certain range.

[0075] In one possible embodiment of this application, another hoisting auxiliary device is provided. Figure 8 This is a side view of another hoisting auxiliary device provided in the embodiments of this application, such as... Figure 8 As shown, the ear plate 100 is provided with at least one auxiliary wheel 600 between the fixed plate 300 and the pulley 200. The auxiliary wheel 600 is used to abut against one side of the flange 710 in the I-beam 700, so that after the fixed plate 300 is pushed into the I-beam 700, the auxiliary wheel 600 can contact the side of the flange 710 of the I-beam 700, which plays a role in stabilizing the hoisting auxiliary device and preventing the hoisting auxiliary device from swaying left and right.

[0076] like Figure 8 As shown, each ear plate 100 has at least one protective plate 110, which is located between the two ear plates 100, and the lower end face of the protective plate 110 is higher than the lower end face of the fixed plate 300, thus protecting the fixed plate 300.

[0077] The actual operation steps of the hoisting auxiliary device provided in this embodiment are as follows:

[0078] Step 1: Align the middle gap of the fixed plate 300 with the web plate 720 of the I-beam 700, while ensuring that the sliding surface of the auxiliary wheel 600 is in contact with the side of the flange 710, and push the hoisting auxiliary device into the predetermined position of the I-beam 700.

[0079] Step 2: According to the installation height requirements of the hoisting auxiliary device, the height of the hoisting auxiliary device is adjusted by passing the connecting screw 510 through different fixing through holes 410. After adjustment, tighten the nut to secure the abutment block 500 and clamp the middle web plate 720 with the abutment block 500.

[0080] Step 3: Drive the fastening bolts into the through holes 310 on the fixed plate 300. The fastening bolts clamp the H-beam 700 in the middle to complete the fixing of the hoisting auxiliary device.

[0081] Step 4: Check whether the I-beam 700 is deformed and whether the hoisting auxiliary device is normal. Check whether the fastening bolts are rusted or deformed, and whether the pulley 200 is damaged or jammed. If there are no abnormalities, proceed to the next step.

[0082] Step 5: Pass the chain hoist through pulley 200, fix one end of the chain hoist to the high-altitude equipment, and pull the other end of the chain hoist to lift it.

[0083] Finally, it should be noted that other embodiments of this utility model will readily occur to those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This utility model is intended to cover any variations, uses, or adaptations of this utility model that follow the general principles of this utility model and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
