DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The technical means that are not described in detail in this application and are not used to solve the technical problems of this application are all set according to the common knowledge in the field, and can be implemented in a variety of common knowledge settings.

[0032] See also Figures 1 to 3 The turning device for overhauling a reducer provided in the present application includes: a base 1, a support plate 11, a bolt assembly 4, a turning pocket 2, a bearing seat 21, an end cover 22, a connecting arm 23, a rotating shaft 212, a back plate 241, an inclined plate 242, a bottom plate 243, a reinforcing plate 244, a hydraulic cylinder assembly 3, a telescopic rod 31, a hydraulic disc 32, a through hole 33, and a support seat 35.

[0033] Rotating shafts 212 are symmetrically arranged on the two side walls of the flip pocket 2, and the rotating shafts 212 are rotatably arranged in the bearing seat 21, and the bearing seat 21 is installed on the top surface of the support plate 11. The support plate 11 is arranged on the top surface of the base 1. The base 1 is disassembled and arranged on the ground through the bolt assembly 4. The base 1 and the support plate 11 can provide reliable support force for the flip pocket 2 when flipping and bearing weight, so as to prevent the overall equipment from tipping over.

[0034] The extended end of the rotating shaft 212 is rotatably mounted in the bearing seat 21, and an end cover 22 is provided on the extended end of the rotating shaft 212 to facilitate protection and maintenance of the rotating shaft 212. The extended end of the rotating shaft 212 is connected to one end of the connecting arm 23, and the other end of the connecting arm 23 is connected to the telescopic rod 31, and the other end of the telescopic rod 31 is drivingly connected to the hydraulic cylinder assembly 3, and the hydraulic cylinder assembly 3 drives the telescopic rod 31 to telescope in the horizontal direction.

[0035] The hydraulic cylinder assembly 3 is installed on the ground outside the flip pocket 2. Driven by the hydraulic cylinder assembly 3, the flip pocket 2 converts the telescopic movement of the telescopic rod 31 into a 90° rotation of the rotating shaft 212 through the connecting arm 23, thereby driving the flip pocket 2 to flip 90°.

[0036] When in use, the reducer to be repaired is transferred by a crane and placed on the flip pocket 2. The flip pocket 2 can be flipped 90° by driving the hydraulic cylinder assembly 3 arranged on both sides of the flip pocket 2. After the telescopic rod 31 arranged on the hydraulic cylinder assembly 3 extends horizontally along the flip pocket 2, it abuts against the connecting arm 23 and drives the rotating shaft 212 to rotate, thereby achieving a 90° flip. Figure 4 As shown, the connecting arm 23 is an arc segment, and the area enclosed by the vertical line connecting the first end and the second end of the connecting arm 23 and the arc segment is 1 / 4 of the full circle area, so the 90° flipping of the flip pocket 2 between two positions can be achieved through the connecting arm 23. The angle between the extended line passing through the center of the rotating shaft 212 connected to the first end of the connecting arm 23 and the extended line passing through the center of the second end of the connecting arm 23 and extending along the telescopic rod 31 at the intersection point is 90°.

[0037] In a specific embodiment, in order to improve the force-bearing reliability of the flip pocket 2, multiple reinforcing plates 44 are arranged at intervals at the top corners of the inner cavity of the flip pocket 2. At the same time, multiple reinforcing plates 44 are also arranged on the outer wall of the back plate 241 of the flip pocket 2.

[0039] In a specific embodiment, it further includes: a connecting sleeve 311 , which is disposed on the extended end of the telescopic rod 31 and connected to one end of the connecting arm 23 .

[0040] In a specific embodiment, the flip pocket 2 includes: a back plate 241, end plates, and a bottom plate 243; the end plates are symmetrically arranged on both sides of the back plate 241; and the bottom plate 243 is arranged on the bottom surfaces of the back plate 241 and the end plates.

[0041] In a specific embodiment, it further includes: an inclined plate 242 ; in order to expand the inner volume of the flip pocket 2 and prevent the reducer from falling out of the flip pocket 2 , the inner side edge of the bottom plate 243 is connected to the back plate 241 through the inclined plate 242 .

[0042] In a specific embodiment, hydraulic discs 32 are respectively provided at both ends of the hydraulic cylinder assembly 3, and through holes 33 are provided on the hydraulic discs 32 to facilitate the hydraulic oil circuit to be connected and provide driving force through hydraulic oil. The hydraulic cylinder assembly 3 is used to drive the turning pocket 2 to turn stably and reliably.

[0043] In a specific embodiment, the single-side support plates 11 of the flip pocket 2 are arranged in pairs to provide reliable supporting force.

[0044] The use of the above-mentioned turning device for speed reducer maintenance can reduce the labor intensity of workers, save time for replacing the oil cylinder, increase the operating rate, and bring significant benefits to the company.
