Description

Technical Field

[0001] This utility model relates to the field of handling device technology, and in particular to a lifting device for a fan. Background Technology

[0002] During the replacement of the annealing furnace blower, the improper specifications of the lifting water pipes used created significant safety hazards. Normally, 6-point water pipes should be used for lifting, but the pipes used were too large to pass through the pre-drilled holes in the blower base. Replacing them with two 4-point pipes proved ineffective due to their insufficient size and load-bearing capacity, causing the pipes to sink during lifting. To prevent the equipment from falling, workers had to lift it by hand, greatly increasing the risk of falling objects and personal injury. This lifting method was not only inefficient but also highly susceptible to pipe slippage or unstable load-bearing, leading to equipment collisions with personnel and seriously threatening operational safety. This highlights the inconvenience and safety hazards caused by the lack of specialized lifting tools in existing technologies. Utility Model Content

Detailed Implementation

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Reference Figures 1 to 4 This utility model provides a lifting device for a fan, and the following embodiments are provided: A lifting device for a fan includes a fixing sleeve 100 and at least two support rods 200. The fixing sleeve 100 includes two fixing walls 110, which are detachably connected circumferentially. When lifting the fan, the two fixing walls 110 of the fixing sleeve 100 are held tightly against the lower part of the fan, and the two fixing walls 110 are connected and fixed to each other. The fixing sleeve 100 is cylindrical, adapted to the shape of the lower end of the fan. In some other embodiments, the cross-section of the fixing sleeve 100 may also be elliptical or rectangular, adapted to the shape of the fixed position.

[0021] The support rod 200 has a fixed end and a connecting end at its two ends. The two fixed ends are fixedly connected to the outer peripheral wall of the fixed sleeve 100 at an annular interval. The connecting end is provided with a laterally extending sleeve 300, which is perpendicular to the extension direction of the support rod 200. The sleeve 300 is used for the lifting rod 400 to pass through. The lifting rod 400 is passed through the sleeve 300, and the fan is lifted for maintenance work. The fan can be lifted with a lifting rod 400 of any diameter, and the fan is firmly fixed, improving maintenance safety. It is compatible with various models of fans, improving adaptability.

[0022] Specifically, the two ends of the two fixed walls 110 are hinged together by a hinge structure and detachably connected by a locking structure. The hinge structure is preferably a hinge, which is fixedly installed at the corresponding ends of the two fixed walls 110, so that the fixed walls 110 can rotate relative to each other, facilitating installation and storage.

[0023] The locking structure includes two fixing rings 111 respectively fixedly disposed on two fixed walls 110, and a pin 112 for insertion and fixation. The four fixing rings 111 are arranged vertically at intervals, that is, two fixing rings 111 are provided at the end of each fixed wall 110. In the fixed state, the pin 112 passes through the four fixing rings 111 in sequence, thereby firmly locking the two fixed walls 110. Further, the pin 112 is provided with an integrally formed or fixedly connected stop 113. The stop 113 is located on the upper part of the pin 112. When the pin 112 is inserted into the fixing ring 111, the stop 113 abuts against the uppermost fixing ring 111, effectively preventing the pin 112 from accidentally slipping downwards due to vibration or gravity, thereby improving the reliability and safety of locking.

[0024] During use, the two fixed walls 110 are first unfolded and positioned at the lower end of the fan via the hinge structure. Then, the pins 112 are inserted from top to bottom into the four fixing rings 111 until the stop block 113 contacts the upper fixing ring 111, thus completing the locking and fixing. This structure is easy to operate, provides a stable connection, and enables quick installation and disassembly of the fixed walls 110, which improves assembly efficiency and facilitates subsequent maintenance and cleaning.

[0025] As one embodiment of the present invention, the locking structure may also adopt other forms of plug-in locking, such as providing a pin hole at the end of the pin 112 and using a cotter pin for fixing, or using a spring pin structure to achieve self-locking, all of which are within the protection scope of the present invention.

[0026] The beneficial effects of this structure are as follows: through the cooperation of the hinge structure and the latch 112, the fixed wall 110 can be opened and closed quickly and reliably fixed, which greatly improves the ease of assembly and operational efficiency; the setting of the stop block 113 further enhances the anti-disengagement performance of the latch 112, is suitable for vibration environments, and improves the stability and safety of the overall structure; at the same time, the latch structure is simple, low in cost, and easy to promote and use.

[0027] In some other embodiments, the two fixed walls 110 may also be fixed together by screws.

[0028] In some other embodiments, the number of fixed walls 110 can be three or four, and corresponding support rods 200 can be provided so that multiple people can lift the fan at the same time, depending on the weight of the fan.

[0029] Furthermore, the inner wall of the fixing sleeve 100 can be provided with an anti-slip pad layer. This anti-slip pad layer is made of rubber and has a diamond-shaped anti-slip texture on its surface, which can effectively increase the friction between the fixing sleeve 100 and the outer peripheral wall of the fan, preventing relative slippage of the fan during lifting and transportation, and further improving the stability and safety of lifting and transportation. The anti-slip pad layer is glued to the inner wall of the fixing ring 111 with strong adhesive. Its thickness can be adjusted according to the actual size of the outer peripheral wall of the fan to ensure a tight fit on fans of different diameters. At the same time, the anti-slip pad layer has a certain elastic deformation capacity, which can play a buffering role when the fixing sleeve 100 clamps the fan, avoiding scratch damage to the fan surface caused by rigid contact.

[0030] Furthermore, referring to Figure 3 Multiple diagonal braces 310 are provided between the sleeve 300 and the support rod 200. The stability of the triangle enhances the structural strength. Furthermore, a lifting rod 400 is inserted inside the sleeve 300, and the two are detachably connected for easy storage and transportation. The sleeve 300 has a rectangular cross-section, and the lifting rod 400 has a connecting section that snaps into and fits into the sleeve 300. Compared to a circular section, a square tube is less prone to lateral movement. Furthermore, when both cross-sections are circular, the sleeve 300 and the lifting rod 400 are interlocked and fixed to each other to prevent relative sliding along the circumference.

[0031] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
