Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically a heating device for disassembling locomotive bearings. Background Technology

[0002] In the maintenance and repair of railway locomotives, bearing removal is a common and crucial operation. To facilitate bearing removal, a specialized bearing heater is typically used to heat the bearing, causing the inner ring to expand and thus reducing the tightness of the fit between the bearing and the shaft, allowing the bearing to be easily removed from the shaft.

[0003] Existing bearing heaters pose certain safety hazards during practical use. Due to their extremely high surface temperatures, reaching hundreds of degrees Celsius or even higher, and the complex working environment of locomotive maintenance workshops with frequent personnel movement and relatively confined workspaces, workers are prone to accidentally touching the heater while it is in operation due to negligence or mishap. This can easily lead to serious burns, causing direct harm to workers and potentially interrupting maintenance work, affecting the efficiency and quality of locomotive maintenance, increasing maintenance costs and time, and causing considerable inconvenience. Therefore, based on these shortcomings, a heating device for locomotive bearing disassembly is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a heating device for disassembling locomotive bearings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating device for disassembling locomotive bearings, comprising a bearing heater body, a housing mounted on the right side of the bearing heater body, a motor screwed to the bottom of the inner cavity of the housing, a screw rod mounted on the output end of the upper surface of the motor, and the other end of the screw rod rotatably connected to the inner wall of the housing via a bearing, guide rods provided at both the front and rear ends of the right side of the inner cavity of the housing, a base sleeved on the outer wall of the screw rod and the guide rod, the base and the screw rod being threaded together, a connecting seat mounted on the left side of the base, and the other end of the connecting seat extending out of the left end face of the housing, coil springs mounted at both the front and rear ends of the left and right sides of the inner cavity of the bearing heater body, connecting rods mounted on the inner sides of the two coil springs, a protective cloth fixedly wrapped around the outer wall of the connecting rod, and the other end of the protective cloth extending out of the upper surface of the bearing heater body and fixedly connected to the bottom end of the connecting seat.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This heating device for locomotive bearing disassembly allows for conventional heating and disassembly operations of the bearing through the bearing heater body. Through the cooperation between the motor, screw, guide rod, base, and connecting seat, one end of the protective cloth can be pulled up or down, while the other end of the protective cloth will drive the connecting rod to rotate clockwise or counterclockwise through the cooperation of the coil spring. The device has a simple structure and reasonable design. Its lifting method can isolate the heater in operation from the outside world, thereby effectively avoiding accidental contact.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3This utility model provides a technical solution: a heating device for disassembling locomotive bearings, including a bearing heater body 1, a housing 2 installed on the right side of the bearing heater body 1, a motor 3 screwed to the bottom of the inner cavity of the housing 2, a screw 4 installed at the output end of the upper surface of the motor 3, and the other end of the screw 4 rotatably connected to the inner wall of the housing 2 through a bearing, guide rods 5 are provided at both the front and rear ends of the right side of the inner cavity of the housing 2, a base 6 is sleeved on the outer wall of the screw 4 and the guide rod 5, and the base 6 and the screw 4 are threaded together, a connecting seat 7 is installed at the left side of the base 6, and the other end of the connecting seat 7 extends out of the left end face of the housing 2, coil springs 8 are installed at both the front and rear ends of the left and right sides of the inner cavity of the bearing heater body 1, a connecting rod 9 is installed on the inner side of the two coil springs 8, a protective cloth 10 is fixedly wrapped around the outer wall of the connecting rod 9, and the other end of the protective cloth 10 extends out of the upper surface of the bearing heater body 1 and is fixedly connected to the bottom end of the connecting seat 7.

[0017] As a preferred option, furthermore, heat dissipation holes 11 are provided on the outer wall of the housing 2, through which ventilation and heat dissipation treatment can be carried out inside the housing 2.

[0018] As a preferred option, the length of the screw 4 is greater than the height of the heater on the bearing heater body 1, so as to ensure that when the protective cloth 10 is pulled out by the connecting seat 7, the protective cloth 10 can completely block the work station.

[0019] As a preferred option, the connector 7 is further shaped like a "C".

[0020] As a preferred option, a rubber pad is provided on the bottom surface of the connector 7. The rubber pad can reduce the hard contact between the connector 7 and other structural components and extend its service life.

[0021] All electrical components mentioned in this solution are existing technologies, and their models are only one of them. Any electrical component that meets the requirements of this solution can be used.

[0022] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control. The specific work is as follows.

[0023] In use, place the bearing to be processed on the workstation, turn on motor 3, and motor 3 will drive screw 4 to rotate. The rotating screw 4 will cause base 6, which is threaded onto its outer wall, to move connecting seat 7 and one end of protective cloth 10 upwards or downwards together. When one end of protective cloth 10 moves upwards with connecting seat 7, the other end of protective cloth 10 will pull connecting rod 9 to rotate clockwise and apply pressure to coil spring 8. At this time, protective cloth 10 will gradually be pulled out from the inner cavity of bearing heater body 1 and block the front and rear sides of the workstation. Protective cloth 10 can isolate the workstation from the outside world and prevent workers from accidentally touching it. Turn on bearing heater body 1. The bearing heater body 1 can perform conventional heating and disassembly operations on the bearing. After the bearing is processed, the control motor 3 moves the base 6 and the connecting seat 7 down together. At this time, since the external force pressing on the coil spring 8 disappears, it can return to its initial state. That is, the coil spring 8 will drive the connecting rod 9 to rotate counterclockwise, so that the protective cloth 10 can be moved back into the bearing heater body 1 and rolled up on the outer wall of the connecting rod 9. Finally, the processed bearing can be taken out. The device uses a lifting method to isolate the heater in operation from the outside world, thereby effectively avoiding accidental contact. It is highly safe, easy to use, practical, and suitable for promotion.
