Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and particularly relates to a disassembly and suspension device for a feeding crane reduction motor. Background Art

[0002] The function of the feeding crane is to pick up the materials transported from the upstream and feed them into the storage cabinet to form a stored material with a certain layer height. According to the structural characteristics of the feeding crane equipment, the feeding crane is respectively driven by a reduction motor for the conveyor belt and a reduction motor for the wheel to travel. Both reduction motors are directly connected to the transmission shaft of the feeding crane, and all connecting components are rigidly connected. Since the feeding crane starts, reverses, and operates frequently, and the starting torque impact force of the reduction motor is large during the reverse operation, the connecting components often become loose or the transmission shaft breaks, resulting in equipment failures. When the transmission shaft of the feeding crane becomes loose or breaks, the transmission shaft needs to be replaced. At this time, professional tools are required to disconnect the motor from the transmission shaft of the feeding crane, then replace the new transmission shaft, and then install the reduction motor on the new transmission shaft. The entire process is carried out at high altitude, which is dangerous and has a high maintenance cost. Multiple people are required to operate to disconnect the reduction motor from the crane transmission shaft. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a disassembly and suspension device for a feeding crane reduction motor, so as to realize that the disassembly and installation of the feeding crane reduction motor can be carried out by only one person.

[0004] The present invention is realized through the following technical solutions:

[0005] A disassembly and suspension device for a feeding crane reduction motor, the transmission shaft of the feeding crane is connected to the output shaft of the reduction motor. It is assumed that the axis of the transmission shaft of the feeding crane extends in the left-right direction. A motor suspension part is provided at the top of the reduction motor, and a suspension hole extending in the left-right direction is opened on the motor suspension part. The suspension device includes a connecting plate detachably installed on the feeding crane frame. One side of the connecting plate is provided with a mounting plate. The mounting plate is located above the feeding crane. Two suspension components are provided at the bottom of the mounting plate opposite to each other left and right. A suspension rod extending in the left-right direction is detachably installed on the two suspension components. The suspension hole of the motor suspension part is sleeved on the suspension rod, and the motor suspension part can slide left and right at the part between the two suspension components on the suspension rod.

[0006] Further, in the two suspension components at the bottom of the connecting plate, a through hole is opened on one suspension component, and a threaded hole is opened on the other suspension component. The suspension rod is a screw rod. The rod part of the screw rod passes through the through hole and the threaded hole in sequence and then a nut is screwed on to realize the detachable installation between the screw rod and the two suspension components, and the screw rod, the through hole, and the threaded hole are coaxially arranged.

[0007] Further, a plurality of waist-shaped holes are formed in the connecting plate, and bolts are passed through the waist-shaped holes and screwed into the laying trolley frame to realize the installation of the connecting plate and the laying trolley frame.

[0008] The present invention has the following advantages compared with the prior art:

[0009] A suspension device for disassembling a reduction motor of a laying trolley provided by the present invention installs a suspension device on the laying trolley frame. The suspension rod on the suspension device is slidably matched with the suspension hole of the motor suspension part. On the one hand, it realizes the suspension support of the reduction motor, and on the other hand, it realizes the guiding of the left and right sliding of the reduction motor, which is convenient for the reduction motor to leave the transmission shaft of the laying trolley and leave space for the replacement of the transmission shaft. After the transmission shaft is replaced, the reduction motor is slid back to the original position along the same path, ensuring the accuracy of the cooperation between the reduction motor and the transmission shaft. It can be operated by a single person in a narrow space at high altitude, and the operation is time-saving and labor-saving, effectively improving the maintenance efficiency of the equipment.

[0015] The embodiments of the present invention will be described in detail below. The following embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments.

[0016] See Figures 1 to 4 , this embodiment provides a suspension device for disassembling a reduction motor of a laying trolley. The transmission shaft 2 of the laying trolley 1 is connected to the output shaft of the reduction motor 3. It is assumed that the axis of the transmission shaft 2 of the laying trolley 1 extends in the left-right direction. A motor suspension part 4 is provided at the top of the reduction motor 3, and a suspension hole extending in the left-right direction is formed in the motor suspension part 4.

[0017] The suspension device includes a connecting plate 5 detachably mounted on the frame of the material spreading trolley 1. On one side of the connecting plate 5, there is a mounting plate 6 which can be a U-shaped channel steel. The mounting plate 6 is located above the material spreading trolley 1. At the bottom of the mounting plate 6, there are two hanging components 7 opposite to each other left and right. A hanging rod 8 extending in the left-right direction is detachably mounted on the two hanging components 7. The hanging hole of the motor hanging part 4 is sleeved on the hanging rod 8, and the motor hanging part 4 can slide left and right on the part of the hanging rod 8 between the two hanging components 7.

[0018] Of the two hanging components 7 at the bottom of the connecting plate 5, a through hole is opened on one hanging component 7, and a threaded hole is opened on the other hanging component 7. The hanging rod 8 is a screw rod. The rod part of the screw rod sequentially passes through the through hole and the threaded hole and then a nut 9 is screwed on to realize the detachable installation between the screw rod and the two hanging components 7, and the screw rod, the through hole, and the threaded hole are coaxially arranged.

[0019] A number of waist-shaped holes 10 are opened on the connecting plate 5. The connecting plate 5 is installed on the frame of the material spreading trolley 1 by bolts 11 passing through the waist-shaped holes 10 and screwing into the frame of the material spreading trolley 1. By adjusting the up and down positions of the bolts 11 in the waist-shaped holes 10, the vertical position of the connecting plate 5 can be adjusted, and further the up and down positions of the hanging rod 8 can be finely adjusted to accurately match the hanging holes of the motor hanging part 4 of the reduction motor 3.

[0020] When it is necessary to replace the transmission shaft 2 of the material spreading trolley 1, first install the connecting plate 5 on the frame of the material spreading trolley 1, then the rod part of the screw rod sequentially passes through the through hole of one hanging component 7, the hanging hole of the motor hanging part 4 and then screws into the threaded hole of the other hanging component 7. The rod part of the screw rod passes through the threaded hole of the other hanging component 7 and a nut 9 is screwed on. Under the limiting action of the head of the screw rod and one hanging component 7, and the limiting action of the nut 9 and the other hanging component 7, the screw rod will not move left and right. At this time, the suspension support of the reduction motor 3 is completed. Then use a disassembly tool to remove the reduction motor 3 from the transmission shaft 2 of the material spreading trolley 1, and let the reduction motor 3 slide left along the hanging rod 8 to make the reduction motor 3 leave the transmission shaft 2. After replacing the new transmission shaft 2, then move the reduction motor 3 to the right to install the reduction motor 3 with the transmission shaft 2.

[0021] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
