Description

Technical Field

[0001] The utility model relates to the technical field of locking head hoisting balance, in particular to a locking disk hoisting device. Background Art

[0002] Locking discs are a common method for external connection of mechanical components, especially in the wind turbine gearbox industry. Low-speed locking discs are large and heavy, typically weighing 1-3 tons. They are required for product testing and rack installation. They are typically installed vertically on the outer circle. Due to design strength issues, the outer circle of the locking disc cannot be designed with lifting holes. Using end-face screw holes for lifting not only makes it difficult to adjust the level, but also forces the inner ring of the locking disc to deform due to gravity. The thin inner ring is easily deformed, and the clearance between the inner ring's inner hole and the outer circle of the shaft is within 0.25mm. This deformation makes it difficult to fit the locking disc onto the outer circle of the shaft. Therefore, currently, the only way to lift the locking disc is to use a sling to hold the outer circle of the locking disc.

[0003] During the installation of the sling, if the operation is carried out on the ground, the locking disc is prone to tipping over. Therefore, the locking disc must be lifted through the inner hole first, and then the outer circle of the locking disc must be locked with the sling. This not only requires the coordination of large and small hooks on the crane, but also requires repeated adjustment of the locking disc position and leveling of the inner hole of the locking disc. This leads to low lifting efficiency and a large workload. In addition, there is a safety risk of the locking disc slipping during the lifting process using the sling. Therefore, when lifting medium and large locking discs, how to quickly balance the center of gravity of the locking disc and achieve safe lifting is an urgent problem that needs to be solved. Utility Model Content

[0004] The utility model aims to provide a locking disk hoisting device to solve the problems of low locking disk hoisting efficiency and high safety risks in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a locking plate lifting device, including a lifting assembly and a fixing assembly, the lifting assembly includes a balancing arm, an arm support plate and an arm fixing plate, the balancing arm and the arm fixing plate are respectively vertically fixed on both sides of the arm support plate, and a lifting hole is provided on the balancing arm; the fixing assembly includes a left hook and a right hook, the left hook is fixedly connected to the arm fixing plate, and a right connecting rod is provided between the right hook and the arm fixing plate, the upper end of the right connecting rod is fixed to the arm fixing plate, and the lower end is detachable and rotatably connected to the right hook, the bottom ends of the left hook and the right hook are vertically provided with support blocks, the support blocks are in contact with the outer circle of the outer ring of the locking plate, and the left hook, the right hook and the arm fixing plate are all provided with strip fixing holes, and the length and width of the strip fixing holes are both larger than the diameter of the bolt hole of the locking plate.

[0006] The principles and advantages of this solution are:

[0007] In actual application, place the left and right hooks on one side of the locking plate mounting bolts and make the lifting device contact with the locking plate, with the support plate close to the outer circle of the locking plate. Then adjust the position of the lifting device and swing the right hook so that the three strip fixing holes on the lifting device are aligned with the bolts on the locking plate respectively. Then remove the bolts at this location and use the bolts to pass through the strip fixing holes to fix the lifting device and the locking plate again. Then use the lifting equipment to lift the lifting device and the locking plate as a whole through the lifting holes on the balance boom for assembly with the shaft.

[0008] 1. Compared with the existing technology that uses slings for lifting, the lifting device of this solution does not need to lift the locking plate in advance. It only needs to align the bar fixing holes with the corresponding bolt holes on the locking plate to connect them. There is no need for frequent adjustments, and lifting can be achieved quickly. Moreover, whether the locking plate is in a horizontal or vertical state, the lifting and fixing operation can be achieved on the ground, which has high lifting efficiency and reduced lifting and assembly difficulty.

[0009] 2. Compared with the existing technology of using slings for lifting, the lifting device and the locking plate in this solution are fixed with bolts, and the three bolts are positioned in a triangle, so that a stable connection is achieved between the lifting device and the locking plate to avoid slipping, and effectively eliminate the safety hazard of the locking plate falling off during lifting.

[0010] 3. The strip-shaped fixing hole design and the rotation design of the right hook in this solution make the lifting device applicable to locking plates of different sizes, and the lifting device has good versatility.

[0011] Furthermore, the right connecting rod and the right hook are both provided with connecting holes, which are aligned with each other and are equipped with joint bolts, so as to facilitate the adjustment of the position of the right hook, realize quick adjustment and assembly, and improve the efficiency of hoisting and assembly.

[0012] Furthermore, the right connecting rod is in a broken line shape, and its lower end is bent in a direction deviating from the left hook.

[0013] On the one hand, the above arrangement increases the overall rotation range of the right hook, making it suitable for locking plates of more sizes. On the other hand, it makes the distance between the left and right hooks farther, ensuring that the connection points between the lifting device and the locking plate are more dispersed and the connection is more stable.

[0014] Furthermore, the hoisting holes on the balancing boom are arranged in two rows transversely, and the two rows of hoisting holes are staggered.

[0015] The two rows of staggered lifting holes are designed to allow for lifting adjustments of locking discs of different sizes and weights to be adjusted during lifting, thereby achieving rapid lifting.

[0016] Furthermore, both the left and right hooks are equipped with positioning blocks above the support blocks and inside the boom fixing plate. These positioning blocks contact the outer end surface of the locking plate. These positioning blocks effectively ensure that the entire lifting device remains flush with the end surface of the locking plate, thereby ensuring that the inner hole of the locking plate is vertical and accurately assembled with the shaft. Furthermore, the positioning blocks reduce the contact area between the lifting device and the end surface of the locking plate, thereby reducing friction and wear.

[0017] Furthermore, horizontal lifting holes are provided on the left hook, the right hook and the boom fixing plate.

[0018] The lifting device of this solution is mainly for medium and large locking discs. The outer diameter of the locking disc is 1000mm-2000mm, so the overall size of the lifting device is relatively large. When the locking disc is in a horizontal state, the horizontal lifting hole can facilitate the rapid leveling of the entire lifting device, reducing manual labor intensity and improving lifting and assembly efficiency.

[0019] Furthermore, the positioning block and the support plate are both provided with protective pads on the side facing the locking disc, and the protective pads are made of rubber material to avoid scratching the surface of the locking disc and maintain the appearance of the product.

[0020] Furthermore, reinforcing ribs are provided between the boom support plate, the boom fixing plate, and the balance boom and the boom support plate to ensure the rigidity of the main body of the hoisting device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is further described in detail through specific implementation methods:

[0024] The reference numerals in the drawings of the specification include: lifting device 100, balancing boom 101, boom support plate 102, boom fixing plate 103, left hook 104, right hook 105, right connecting rod 106, joint bolt 107, positioning block 108, support block 109, connecting bolt 110, strip fixing hole 111, horizontal lifting hole 112, locking plate 300, outer ring 301, inner ring 302 and bolt 303

[0025] The embodiment is basically as shown in the attached Figure 1-Figure 2 As shown:

[0026] A locking plate lifting device 100 includes a lifting component and a fixing component. The lifting component includes a balancing arm 101, an arm support plate 102 and an arm fixing plate 103. The balancing arm 101 and the arm fixing plate 103 are respectively fixed vertically on both sides of the arm support plate 102, and reinforcing ribs are provided between the arm support plate 102 and the arm fixing plate 103, as well as between the balancing arm 101 and the arm support plate 102 to ensure the rigidity of the lifting device 100 body; lifting holes are opened on the balancing arm 101, which are arranged in two rows horizontally, and the two rows of lifting holes are staggered to meet the lifting adjustment of locking plates 300 of different sizes and different weights during lifting, thereby realizing rapid lifting.

[0027] The fixing assembly includes a left hook 104 and a right hook 105, the left hook 104 is fixedly connected to the boom fixing plate 103, and a right connecting rod 106 is provided between the right hook 105 and the boom fixing plate 103, the upper end of the right connecting rod 106 is fixed to the boom fixing plate 103, and the lower end is detachably and rotatably connected to the right hook 105, and the right connecting rod 106 and the right hook 105 are both provided with connecting holes, and the connecting holes of the two are aligned and joint bolts 107 are installed in the connecting holes to realize rotation adjustment of the right hook 105; the right connecting rod 106 is in a broken line shape, and its lower end is bent in a direction deviating from the left hook 104, on the one hand, the overall rotation range of the right hook 105 is increased, and more sizes of locking plates 300 can be applied, and on the other hand, the distance between the left hook 104 and the right hook 105 is made farther, ensuring that the connection points between the lifting device 100 and the locking plate 300 are more dispersed and the connection is more stable. The left hook 104, the right hook 105 and the boom fixing plate 103 are all provided with a strip-shaped fixing hole 111, and the length and width of the strip-shaped fixing hole 111 are both larger than the bolt hole diameter of the locking plate 300; the above-mentioned strip-shaped fixing hole 111 design and the rotation design of the right hook 105 enable the lifting device 100 to be suitable for locking plates 300 of different sizes, and the lifting device 100 has good versatility.

[0028] A support block 109 is vertically provided at the bottom end of the left hook 104 and the right hook 105. The support block 109 contacts the outer circle of the outer ring 301 of the locking disk 300. The left hook 104 and the right hook 105 are provided with a positioning block 108 above the support block 109 and on the inner side of the boom fixing plate 103. The positioning block 108 contacts the end face of the outer ring 301 of the locking disk 300, and the positioning block 108 and the support plate facing the locking disk 300 are provided with a protective pad (not shown in the figure). The protective pad is made of rubber material to avoid scratching the surface of the locking disk 300 and ensure the appearance of the product.

[0029] Preferably, horizontal lifting holes 112 are provided on the left hook 104, the right hook 105 and the boom fixing plate 103. The lifting device 100 of this scheme is mainly aimed at medium and large locking plates 300. The outer diameter of the locking plate 300 is close to or even exceeds 1 meter. Therefore, the overall size of the lifting device 100 is relatively large. When the locking plate 300 is in a horizontal state, the horizontal lifting holes 112 can facilitate the rapid leveling of the lifting device 100 as a whole, reduce manual labor intensity, and improve lifting and assembly efficiency.

[0030] Compared with the prior art that uses slings for lifting, the lifting device 100 of this solution does not need to lift the locking plate 300 in advance. It only needs to align the bar-shaped fixing holes 111 with the corresponding bolt holes on the locking plate 300 for connection. No frequent adjustments are required, and lifting can be achieved quickly. Moreover, regardless of whether the locking plate 300 is in a horizontal or vertical state, the lifting and fixing operation can be achieved on the ground, which has high lifting efficiency and reduced lifting assembly difficulty. Secondly, in this solution, the lifting device 100 and the locking plate 300 are fixed with bolts, and the three bolts are positioned in a triangle, so that a firm connection is achieved between the lifting device 100 and the locking plate 300 to avoid slipping, effectively eliminating the safety hazard of the locking plate 300 falling off during lifting.

[0031] The specific implementation process is as follows:

[0032] The locking disc 300 has a structure as follows: Figure 2 As shown, it consists of an outer ring 301 , an inner ring 302 and bolts 303 .

[0033] When the locking plate 300 is placed horizontally, the lifting device 100 is hoisted levelly through the lifting hole and placed above the locking plate 300. The position of the right hook 105 is adjusted so that the three strip fixing holes 111 correspond to the bolt holes on the locking plate 300. The bolts at the corresponding positions on the locking plate 300 are removed, and the support block 109 contacts the outer circle of the outer ring 301 of the locking plate 300, and the positioning block 108 contacts the end face of the outer ring 301 of the locking plate 300. The connecting bolts 110 are passed through the strip fixing holes 111 to fix the lifting device 100 to the locking plate 300. The locking plate 300 is lifted by the lifting hole on the balancing arm 101 to be placed vertically and the center of gravity is adjusted to achieve horizontal lifting and assembly onto the axis.

[0034] When the locking plate 300 is placed vertically, the lifting device 100 is adjusted to a vertical state through the lifting hole on the balancing arm 101, and placed at the front end of the locking plate 300. The bolts at the corresponding position of the locking plate 300 are removed, and the lifting device 100 is installed. After fixing, the center of gravity is adjusted to lift the locking plate 300.

[0035] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
