Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a motor hoisting bracket. Background Technology

[0002] The motor hanger is an important component of the bogie crossbeam, used to suspend the motor during lifting. Figure 1 As shown, the existing motor mounting bracket is generally composed of an upper cover plate 1.1, a lower cover plate 1.2, a side upright plate 1.3, and a stiffening plate 1.4. The motor is fastened with bolts at the holes of the auxiliary parts of the upper cover plate 1.1 and the holes of the auxiliary parts of the side upright plate 1.3. The built-in stiffening plate 1.4 enhances the overall structural rigidity.

[0003] However, because the weld at the intersection of the top cover plate, the side upright plate, and the seamless steel pipe of the crossbeam is relatively sharp, sharp points are easily formed when welding the seamless steel pipe of the crossbeam, making it difficult to penetrate the weld and hindering the welding operation. This makes it impossible to guarantee the quality of the weld. Since the entire motor hanger is heavy, the weld is subjected to impact loads, which increases the risk of fatigue cracks and affects the stability of the motor hanger.

[0004] Therefore, there is an urgent need for a motor hanger to solve the above-mentioned technical problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] like Figure 2 As shown, this utility model provides a motor mounting bracket. The motor mounting bracket includes a first upper cover plate 1, a second upper cover plate 2, a vertical plate 3, a lower cover plate 4, and a front end plate 5.

[0030] Specifically, the first upper cover plate 1 is connected to the top wall of the vertical plate 3, the lower cover plate 4 is connected to the bottom wall of the vertical plate 3, the second upper cover plate 2 is arc-shaped, and part of the second upper cover plate 2 is connected to the top wall of the first upper cover plate 1, while the remaining part of the second upper cover plate 2 bends towards the lower cover plate 4. The rear end of the vertical plate 3 is recessed with an arc-shaped groove 31, and the seamless steel pipe is welded to the groove wall of the arc-shaped groove 31. The front end plate 5 is connected to the front end of the vertical plate 3. Compared with the prior art, the motor hanger, by setting the first upper cover plate 1 and the second upper cover plate 2, connects the second upper cover plate 2 to the top wall of the first upper cover plate 1, raising the height of the second upper cover plate 2, thereby increasing the distance between the second upper cover plate 2 and the seamless steel pipe, thus improving the weld space. This avoids the weld joint of the second upper cover plate 2, the vertical plate 3, and the seamless steel pipe being too sharp, facilitating welding operations, improving welding effect, and enhancing the stability of the motor hanger.

[0031] Optionally, the top wall of the first upper cover plate 1 is provided with a plurality of first connecting holes 11 at intervals. The plurality of first connecting holes 11 are used to connect the traction motor, which can improve the stability of the connection between the motor hanger and the traction motor.

[0032] Furthermore, the first connecting hole 11 is a threaded hole, through which the bolt passes and is threaded to the wall of the traction motor, facilitating the installation and removal of the motor mount and the traction motor.

[0033] Optionally, the front end of the upright plate 3 is recessed with a weight-reducing groove 32, so that a first connecting part 33 and a second connecting part 34 are respectively protruding on both sides of the weight-reducing groove 32. The first upper cover plate 1 is connected to the first connecting part 33, and the front end plate 5 is connected to the second connecting part 34. Specifically, the weight-reducing groove 32 recessed at the front end of the upright plate 3 makes the front end of the motor mount have a hollow structure. The open front end can effectively reduce the weight of the motor mount and achieve the lightweighting of the motor mount; at the same time, it increases the welding operation space, which facilitates welding of the first upper cover plate 1, the upright plate 3 and the front end plate 5.

[0034] Optionally, the first upper cover plate 1 is provided with a first mounting portion 12 and a second mounting portion 13. The first mounting portion 12 and the second mounting portion 13 are connected at an angle. The first mounting portion 12 is connected to the first connecting portion 33, and the second mounting portion 13 is connected to the top wall of the upright plate 3. A plurality of first connecting holes 11 are provided in the second mounting portion 13, and a portion of the second upper cover plate 2 is connected to the top wall of a portion of the second mounting portion 13. Specifically, the first mounting portion 12 and the second mounting portion 13 are connected perpendicularly. The first mounting portion 12 is welded to the first connecting portion 33, and the second mounting portion 13 is welded to the top wall of the upright plate 3.

[0035] Furthermore, in this embodiment, the first upper cover plate 1 is provided with two first connecting holes 11, which are spaced apart on the top wall of the remaining second mounting portions 13. Of course, in some other embodiments, the number of first connecting holes 11 is determined according to the actual situation, and will not be described in detail here.

[0036] Optionally, the second mounting part 13 is provided with a protrusion 131, and two first connecting holes 11 are spaced apart on the protrusion 131. Specifically, the first connecting holes 11 are formed on the protrusion 131, which can increase the length of the first connecting holes 11 and improve the stability of the connection between the motor hanger and the traction motor.

[0037] Optionally, the front end plate 5 is provided with a plurality of second connecting holes 51 at intervals. These second connecting holes 51 are used to connect to the lifting motor, which improves the stability of the connection between the motor mount and the lifting motor. Further, the front end plate 5 is provided with two second connecting holes 51. These second connecting holes 51 are open holes. The motor mount also includes fasteners that can pass through the second connecting holes 51 and connect to the lifting motor. Specifically, the fasteners are bolts, which pass through the second connecting holes 51 and are screwed into the threaded holes of the lifting motor for fastening.

[0038] Optionally, in this embodiment, the motor mounting bracket is provided with three upright plates 3, which are spaced apart. The top walls of all three upright plates 3 are connected to the first upper cover plate 1, and the bottom walls of all three upright plates 3 are connected to the lower cover plate 4. Specifically, the three upright plates 3 are parallel and spaced apart, which can improve the overall stability of the motor mounting bracket. Of course, in some other embodiments, the number of upright plates 3 is determined according to the actual situation, which will not be elaborated here.

[0039] Optionally, the first upper cover plate 1 and the second upper cover plate 2 are integrally cast structures, which effectively reduces welding deformation and improves the stability of the motor hanger.
