[0014] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein, and therefore the present invention is not limited to the specific embodiments disclosed below.
[0016] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not specifically singular and may include plural forms. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.
[0017] The frequency converter unit weighs about 165 kg. During installation, it needs to be lifted from the wooden base and then installed. Without the aid of lifting equipment, it is not easy to lift and install manually.
[0018] Therefore, a more efficient installation hoisting tool for frequency converter devices is needed.
[0019] like Figures 1-4 As shown, a mounting fixture for a frequency converter device includes:
[0020] The top frame 101 is connected by four vertically downward support rods 102 installed at the four corners of the top frame. A handle 103 is installed at one end of each support rod 102 that passes through the top frame 101.
[0021] In one embodiment, the top frame 101 includes: two crossbeams 1012, a longitudinal beam 1011 installed between the two crossbeams 1012, and a reinforcing angle 1013 installed between the crossbeams 1012 and the longitudinal beam 1011.
[0022] In one embodiment, at least one reinforcing longitudinal beam is installed between the two crossbeams 1012.
[0023] In one embodiment, the support rod 102 is installed through the connection position between the crossbeam 1012 and the longitudinal beam 1011.
[0024] The top frame 101 is provided with a lifting ring 104, which is installed on the top frame through a split pin 105 and a nut 106.
[0025] In one embodiment, the lifting ring 104 is installed on the cross beam 1012, and the split pin 105 penetrates the cross beam 1012 to fix the lifting ring 104 with the nut 106.
[0026] Specifically, the lifting ring can be fastened by means of a washer and a nut.
[0027] When the lifting device hoists the frequency converter device 200, the support rod 102 is connected to the frequency converter device at the other end of the top frame 101, and the lifting belt 300 of the crab is connected to the lifting ring 104, so that the lifting device and the frequency converter device 200 are lifted and moved to a designated position by lifting the lifting belt 300 of the crab.
[0028] In one embodiment, the support rod 102 is rotated by rotating the handle 103, so that the thread at one end of the support rod 102 connected to the frequency converter device is rotated into the screw hole of the frequency converter device for connection.
[0029] Specifically, the four lifting device handles are manually rotated to rotate the lower end stud of the support rod into the corresponding mounting hole of the frequency converter device, so as to ensure that the lifting device is firmly connected to the device.
[0030] In one embodiment, when the lifting device unloads the frequency converter device, the support rod 102 is rotated by rotating the handle 103, so that the thread at one end of the support rod 102 connected to the frequency converter device is rotated out of the screw hole of the frequency converter device to disconnect, and the lifting device is lifted away by the lifting belt of the crab.
[0031] Specifically, the four lifting device handles are manually rotated in reverse to unload the lifting device from the device, and the lifting device is hoisted back to the lifting device storage place by the crab, completing the installation process. By changing the installation position of the support rod on the frame, the lifting device can be applied to different models of devices.
[0032] Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments according to the needs in order to adapt to specific application occasions without deviating from the principles of the present application.
[0033] It should be noted that in the description of the utility model, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other terms indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is merely for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0034] In addition, it should be further pointed out that in the description of the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0035] In this paper, the orientation terms such as "front", "front side", "front part", "rear", "rear side" and "rear part" are based on the front-rear direction of the vehicle after the component is installed to the vehicle. In this paper, "longitudinal", "longitudinal direction", "longitudinal section" are based on the front-rear direction of the component after the component is installed to the vehicle, and "horizontal", "horizontal direction", "cross section" means perpendicular to the longitudinal direction.
[0036] It should be understood that although the present specification is described according to each embodiment, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be combined to form other embodiments that those skilled in the art can understand.
