It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0025] like Figure 1As shown, a preferred embodiment of the present invention provides a bearing transfer device for a narrow space, which includes a first transfer mechanism 100, a second transfer mechanism 200 and a first screw 300. The first transfer mechanism 100 and the second transfer mechanism 200 both include a pressure plate 101, a sleeve 102, a lower support leg assembly 103 and a roller 1047 assembly 104. The pressure plate 101 is fixedly connected to the sleeve 102, the upper end of the lower support leg assembly 103 is fixedly connected to the sleeve 102, and the lower end of the lower support leg assembly 103 is fixedly connected to the roller 1047 assembly 104. The first screw 300 is connected to the two sleeves 102 and extends at both ends. One end of the first screw 300 is provided with a first threaded portion, and the other end of the first screw 300 is provided with a second threaded portion. A first nut 105 is threadedly connected to the first threaded portion, and a second nut 106 is threadedly connected to the second threaded portion.

[0026] During installation, the bearing is connected to the first screw 300 and is located between the first pressure plate 101 and the second pressure plate 101, and the first nut 105 and the second nut 106 are rotated respectively, so that the first pressure plate 101 and the second pressure plate 101 are close to each other until they respectively abut against the two sides of the bearing to fix the bearing; after the tail pipe is formed, the entire transfer device is hoisted into the end of the tail pipe, and the hoist and the extended cloth belt are used to slowly pull the bearing inside the tail pipe to the installation position, and the setting of the roller 1047 component 104 can ensure that the entire device moves smoothly inside the tail pipe, facilitating the entire transfer process; the use of the utility model can avoid putting the bearing into the tail pipe in advance, thereby avoiding bearing damage and rust, reducing unnecessary rework and equipment replacement work, improving installation efficiency, shortening the construction period, and achieving the purpose of reducing costs and increasing efficiency.

[0027] For example, Figure 2 As shown, there are two lower leg assemblies 103, which are arranged at 90 degrees. A reinforcing rib 108 is provided between the two lower leg assemblies 103 to strengthen the connection strength between the two lower leg assemblies 103 and ensure the stability of the entire device.

Therefore, during specific use, the overall length of the support leg assembly can be adjusted according to the size of the internal space of the tail pipe, which facilitates the transportation of the bearing and has strong adaptability.

[0030] For example, Figure 5 As shown, the roller 1047 assembly 104 includes a top plate 1041, a first side support plate 1042, a second side support plate 1043, a second screw 1044, a third nut 1045, a fourth nut 1046 and a roller 1047, the top plate 1041 is fixed on the first support leg 1031, the first side support plate 1042 and the second side support plate 1043 are fixed on the top plate 1041 and are arranged at intervals, the second screw 1044 is connected to the first side support plate 1042 and the second side support plate 1043, the roller 1047 is provided on the second screw 1044 and is located between the first side support plate 1042 and the second side support plate 1043, the third nut 1045 is threadedly connected to one end of the second screw 1044, and the fourth nut 1046 is threadedly connected to the other end of the second screw 1044.
