Description

Technical Field

[0001] This application relates to the technical field of cold protection for diesel locomotives, and particularly to a cold protection device for diesel locomotives. Background Art

[0002] At the window positions of the power room, electrical room, cooling room, etc. of diesel locomotives, louver structures are adopted. The heat generated by the operation of the internal equipment of the diesel locomotive is discharged through the louvers to prevent danger caused by high temperature inside the diesel locomotive. In winter or cold regions, a cold protection device must be installed at the louver position to prevent the oil and water pipelines in the locomotive head and the braking system of the entire train from freezing due to low temperature, which affects the operation of the diesel locomotive. Most traditional cold protection devices use cold protection quilts, which are directly fixed outside the louvers with iron wires or ropes to play a heat preservation role. However, after the locomotive runs, the cooling water temperature rises with the operation of the diesel engine and needs to dissipate heat and cool down. At this time, the cold protection needs to be opened at a certain angle; when the locomotive stops running and is in a standby state, in order to prevent the cooling water from freezing, the cold protection quilt needs to be completely lowered. The process of opening and closing the above-mentioned cold protection quilt is completely manually operated by train personnel, which not only increases the work of train personnel, but also the cold protection quilt is easily fixed insecurely. If the existing rolling curtain structure is used to control the rolling and unrolling of the cold protection quilt, multiple guide wheels fixed beside the rolling curtain fight for positions when the cold protection quilt is rolled up, resulting in the cold protection quilt being squeezed out, affecting the rolling and unrolling effect, and at the same time, the equipment is easily damaged; if the guide wheels are cancelled, there is no restriction on both sides of the cold protection quilt, and it is easily blown up in strong wind weather, and the cold protection quilt cannot be rolled up flat, affecting the cold protection effect. Content of the Utility Model

[0003] The utility model aims to solve the problems that the manual operation of the cold protection quilt of the above-mentioned diesel locomotive is inconvenient and the existing rolling curtain structure is not suitable for the rolling and unrolling of the cold protection quilt, so as to provide an electronically controlled cold protection device for diesel locomotives.

[0004] The technical solution adopted by the utility model to solve the above problems is as follows:

[0005] A cold protection device for a diesel locomotive, which is applied to the louver of a diesel locomotive, includes a fixed frame, a cold protection quilt and a controller. The fixed frame is fixed on the diesel locomotive around the louver. Limit rings are fixed on both sides of the cold protection quilt, and the limit rings on both sides are respectively movably sleeved on the vertical edges on both sides of the fixed frame. A first motor and a second motor are respectively arranged at the upper end and the lower end of the fixed frame. A first transmission reel is fixed on the output shaft of the first motor, and the upper end of the cold protection quilt is fixed on the first transmission reel. The first motor drives the first transmission reel to rotate, driving the cold protection quilt to roll up or lower; a second transmission reel is fixed on the output shaft of the second motor, and a connecting piece is wound on the second transmission reel. The connecting piece is connected to the lower end of the cold protection quilt, and the controller is used to control the first motor and the second motor to rotate simultaneously.

[0006] The utility model adopting the above technical solution, compared with the prior art, has the following beneficial effects:

[0007] The utility model is provided with a first motor and a second motor, and the first motor and the second motor rotate simultaneously. The first motor drives the cold-proof quilt to roll up or lower, and the connecting piece on the second motor vertically limits the cold-proof quilt to prevent the cold-proof quilt from being blown up in strong wind weather; the two sides of the cold-proof quilt are fixed with limit rings, which are movably sleeved with the fixed frame. When the cold-proof quilt rolls up or lowers, the horizontal direction of the cold-proof quilt is fixed to prevent the cold-proof quilt from being blown up and offset by strong wind; through the device of the utility model, it can be ensured that the cold-proof quilt remains flat when it rolls up or lowers.

[0008] As a preference, a further technical solution of the utility model is:

[0009] A cold-proof quilt cover is sleeved on the first transmission reel, one end of the cold-proof quilt cover is fixed to the upper end of the fixed frame, and a through groove for the cold-proof quilt to pass through is opened on the bottom surface of the cold-proof quilt cover. The cold-proof quilt cover provides an accommodation cavity for the rolled-up cold-proof quilt and can provide shielding for the rolled-up cold-proof quilt.

[0010] An upward limit switch and a downward limit switch are respectively arranged at the upper end and the lower end of the fixed frame, and the upward limit switch and the downward limit switch are connected to the controller. When the limit ring contacts the upward limit switch and the downward limit switch during the process of the cold-proof quilt rolling up or lowering, the first motor and the second motor stop rotating. The upward limit switch and the downward limit switch provide signals for the controller to stop rising and stop descending, which is convenient for intelligent control of the rolling up and lowering of the cold-proof quilt.

[0011] The fixed frame includes a top frame, a bottom frame and a connecting rod connecting the top frame and the bottom frame. The first motor is fixed on one side of the top frame, and the first transmission reel is rotatably connected to the other side of the top frame; the second motor is fixed on one side of the bottom frame, and the second transmission reel is rotatably connected to the other side of the bottom frame.

[0012] The connecting piece is a pull rope, and a plurality of pull ropes are provided. A plurality of sleeves are fixedly sleeved on the second transmission reel, and circumferential grooves are opened on the sleeves. One end of each pull rope is wound in the circumferential groove, and a plurality of pull holes are opened at the bottom end of the cold-proof quilt. The other end of each pull rope is fixed in each pull hole. Through the above structure, it is convenient to limit the cold-proof quilt in multiple vertical directions and increase the vertical limiting effect.

[0013] The upward limit switch and the downward limit switch are arranged on the fixed frame on the same side of the connecting rod, and the cold-proof quilt contacts the other side of the connecting rod. Through the above structure, it is convenient for the cold-proof quilt to drive the limit ring to contact the upward limit switch and the downward limit switch when it rolls up or lowers.

[0019] Refer to Figures 1-3 , an anti-freezing device for diesel locomotives, which is applied to the louvers of diesel locomotives, and includes a fixed frame, a cold-proof quilt 3 and a controller. The fixed frame is fixed on the diesel locomotive around the louvers. The fixed frame includes a top frame 1, a bottom frame 4 and two connecting rods 2. The top frame 1 is fixed on the diesel locomotive above the louvers, and the bottom frame 4 is fixed on the diesel locomotive below the louvers. The top frame 1 and the bottom frame 4 are connected by the connecting rod 2. A first motor 11 is fixed on one inner side of the top frame 1, the output shaft of the first motor 11 is parallel to the length direction of the top frame 1, and the output shaft of the first motor 11 is coaxially fixed with a first driving reel 12, and the other end of the first driving reel 12 is rotatably connected to the other inner side of the top frame 1; A second motor 41 is fixed on one inner side of the bottom frame 4, the output shaft of the second motor 41 is coaxially fixed with a second driving reel 42, and the other end of the second driving reel 42 is rotatably connected to the other inner side of the bottom frame 4; The upper end of the cold-proof quilt 3 is fixed on the first driving reel 12, and the first motor 11 drives the first driving reel 12 to rotate, driving the cold-proof quilt 3 to roll up or lower; The distance between the two connecting rods 2 is slightly smaller than the length of the cold-proof quilt 3. Limit rings 31 are fixed at the lower left corner and the lower right corner of the cold-proof quilt 3, and the limit rings 31 on both sides are respectively movably sleeved on the connecting rods 2 on both sides; A connecting member is wound on the second driving reel 42, and the connecting member is connected to the lower end of the cold-proof quilt 3. The controller is used to control the first motor 11 and the second motor 41 to rotate forward or reverse simultaneously.

[0020] The utility model is provided with a first motor 11 and a second motor 41, and the first motor 11 and the second motor 41 rotate simultaneously. The first motor 11 drives the cold-proof quilt 3 to roll up or lower. The connecting piece on the second motor 41 vertically limits the cold-proof quilt 3 to prevent the cold-proof quilt 3 from being blown up in strong wind weather. Fixed limit rings 31 are provided on both sides of the cold-proof quilt 3 and are movably sleeved with the fixed frame. When the cold-proof quilt 3 rolls up or lowers, the horizontal direction of the cold-proof quilt 3 is fixed to prevent the cold-proof quilt 3 from being blown up by strong wind and offset. Through the device of the utility model, it can be ensured that the cold-proof quilt 3 remains flat when rolling up or lowering.

[0021] In this embodiment, a cold-proof quilt housing 13 is sleeved on the first transmission reel 12. One end of the cold-proof quilt housing 13 is fixed to one inner side of the top frame 1. A through groove for the cold-proof quilt 3 to pass through is formed in the bottom surface of the cold-proof quilt housing 13, and the length and width of the through groove are greater than the length and thickness of the cold-proof quilt 3. When the first motor 11 drives the first transmission reel 12 to rotate forward, the cold-proof quilt 3 is gradually wound around the first transmission reel 12 through the through groove under the drive of the first transmission reel 12. When the first motor 11 drives the first transmission reel 12 to rotate reversely, the cold-proof quilt 3 is gradually lowered through the through groove under the drive of the first transmission reel 12 and covers the fixed frame. The cold-proof quilt housing 13 provides an accommodation cavity for the rolled-up cold-proof quilt 3, can provide shielding for the rolled-up cold-proof quilt 3, and at the same time has effects such as dust prevention and rain protection.

[0022] In this embodiment, an upward limit switch 14 and a downward limit switch 45 are respectively fixed to the lower end of the top frame 1 and the upper end of the bottom frame 4. The upward limit switch 14 and the downward limit switch 45 are connected to the controller. When the limit ring 31 contacts the upward limit switch 14 and the downward limit switch 45 during the process of the cold-proof quilt 3 rolling up or lowering, the first motor 11 and the second motor 41 stop rotating. The upward limit switch 14 and the downward limit switch 45 provide signals for the controller to stop rising and stop descending, so that the cold-proof quilt 3 automatically stops when rolling up or lowering to a certain position, and the control is more intelligent.

[0023] In this embodiment, the connecting member is a drawstring 44. There are multiple drawstrings 44. A plurality of collars 43 are fixedly sleeved on the second transmission reel 42. A circumferential groove is formed in the collar 43. One end of each drawstring 44 is wound in the circumferential groove of the collar 43. A plurality of draw holes 32 are formed at the bottom end of the cold-proof cover 3. The other end of each drawstring 44 is fixed in each draw hole 32. When the first motor 11 and the second motor 41 rotate forward simultaneously, the cold-proof cover 3 is rolled up. Driven by the second motor 41, the drawstring 44 is gradually unfolded. When the first motor 11 and the second motor 41 rotate reversely simultaneously, the cold-proof cover 3 is lowered. Driven by the second motor 41, the drawstring 44 is gradually wound around the collar 43. During the unfolding and winding process of the drawstring 44, the drawstring 44 is always kept taut, so as to ensure that the drawstring 44 straightens the cold-proof cover 3. Through the above structure, it is convenient to limit the cold-proof cover 3 in multiple vertical directions and increase the vertical limiting effect.

[0024] In this embodiment, the upward limit switch 14 and the downward limit switch 45 are arranged on the top frame 1 and the bottom frame 4 on the same side of the connecting rod 2, and the side walls of the upward limit switch 14 and the downward limit switch 45 are in contact with the connecting rod 2. The cold-proof cover 3 is in contact with the other side of the connecting rod 2. Through the above structure, it is convenient for the cold-proof cover 3 to drive the limit ring 31 to contact the upward limit switch 14 and the downward limit switch 45 when the cold-proof cover 3 is rolled up or lowered.

[0025] The working principle of this embodiment is as follows: When the cold-proof cover 3 needs to be rolled up, control the first motor 11 and the second motor 41 to rotate forward simultaneously. Under the action of the first transmission reel 12, the cold-proof cover 3 is gradually wound around the first transmission reel 12. The second motor 41 drives the drawstring 44 to gradually extend. The upper end of the drawstring 44 gradually moves upward under the drive of the cold-proof cover 3, so as to ensure that the cold-proof cover 3 is straightened as a whole when rising. The limit ring 31 gradually moves upward on the connecting rod 2 under the drive of the cold-proof cover 3, ensuring that the cold-proof cover 3 moves upward straight in the horizontal direction. When the limit ring 31 contacts the upward limit switch 14, the upward limit switch 14 sends a signal to stop rising to the controller, and the controller controls the first motor 11 and the second motor 41 to stop rotating forward. When the cold-proof cover 3 needs to be lowered, control the first motor 11 and the second motor 41 to rotate reversely simultaneously. Under the action of the first transmission reel 12, the cold-proof cover 3 is gradually unfolded. The second motor 41 drives the drawstring 44 to gradually wind around the collar 43, so as to straighten the cold-proof cover 3 as a whole when descending. The limit ring 31 gradually moves downward on the connecting rod 2 under the drive of the cold-proof cover 3, ensuring that the cold-proof cover 3 descends vertically straight in the horizontal direction. When the limit ring 31 contacts the downward limit switch 45, the downward limit switch 45 sends a signal to stop descending to the controller, and the controller controls the first motor 11 and the second motor 41 to stop rotating reversely. At this time, the cold-proof cover 3 completely covers the fixed frame, that is, covers the outside of the shutter.
