Description

Technical Field

[0001] The utility model relates to the technical field of railway locomotives, in particular to a lifting stopper. Background Art

[0002] In the field of transportation equipment, lifting stops are often needed. When lifting a railway locomotive, the locomotive may shake during the lifting process, so the car body and the running gear of the locomotive are usually lifted separately, that is, the car body is lifted first and then the running gear is lifted. This lifting method has certain defects. First, the two liftings will take a certain amount of time. Secondly, the operation is cumbersome. When lifting the car body, it is usually necessary to prepare the running gear of another locomotive to place the car body, and then after the running gear of the car body itself lands, the car body is placed on its own running gear. The operation is more complicated and troublesome. For this reason, we propose a lifting stop. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] See also Figure 1-6 The utility model provides a technical solution: a lifting stopper, including a frame 1, the frame 1 is the running part of the rail locomotive, including locomotive wheels, a base, a fixing frame, etc., and a vehicle body is placed on the frame 1. This is the existing technology, and also includes:

[0028] A lifting block 2, the lifting block 2 is rotatably arranged on the vehicle frame 1, and a hole for lifting is opened on the lifting block 2;

[0029] A stop rod 3, which is slidably disposed in the frame 1, and is provided in plurality, and is respectively located on both sides of the frame 1;

[0030] The transmission assembly 4 is arranged on the vehicle frame 1, and the lifting block 2 is rotated, and the stop rod 3 is driven to slide through the transmission assembly 4, so as to stop the vehicle body on the vehicle frame 1. Specifically, the transmission assembly 4 includes a shaft 1 41 rotatably arranged on the vehicle frame 1, the shaft 1 41 is fixedly connected to the lifting block 2, a transmission pulley 42 is installed on the shaft 1 41, a shaft 2 43 is rotatably arranged in the vehicle frame 1, and a transmission pulley 42 is also fixedly connected to the shaft 2 43, a transmission belt 1 44 is arranged between the two transmission pulleys 42, and the transmission belt 1 44 contacts and resists the two transmission pulleys 42 at the same time and rotates;

[0031] When the entire rail locomotive needs to be lifted up, the lifting block 2 is rotated. The lifting block 2 is originally located under the frame 1 and is put away when not in use to save space. The lifting operation is performed through the lifting holes on the lifting block 2. After the lifting block 2 is rotated, it drives the shaft 1 41 to rotate, and then drives the transmission pulley 42 to rotate, thereby driving the transmission belt 1 44 to rotate, and then drives another transmission pulley 42 to rotate, thereby driving the shaft 2 43 to rotate, and then drives the gear plate 51 to rotate, thereby driving another gear plate 51 to rotate, and then drives the shaft 3 52 to rotate, thereby driving the rod 1 53 to deflect and tilt, and then drives the stop rod 3 to deflect and tilt, and slide out through the frame 1. At this time, the stop rod 3 is located obliquely above the frame 1, and is used to horizontally stop the car body on the frame 1 to facilitate lifting.

[0032] A sliding assembly 5 is provided on the second shaft 43, and the stop rod 3 is driven to move by the sliding assembly 5. Specifically, a toothed disc 51 is fixedly connected to the second shaft 43, and a third shaft 52 is rotatably provided in the frame 1. The toothed disc 51 is also fixedly provided on the third shaft 52. The two toothed discs 51 are meshed with each other. A rod 1 53 is fixedly installed on the third shaft 52. The rod 1 53 is rotatably connected to the stop rod 3 through a rotating shaft, and the stop rod 3 is located in the frame 1 and slides.

[0033] A torsion spring 6 is provided on the second shaft 43, and the two ends of the torsion spring 6 are respectively fixedly connected to the second shaft 43 and the frame 1, so as to drive the second shaft 43 to automatically return to its position through the elastic force of the torsion spring 6. The advantage of the torsion spring 6 is that when the lifting block 2 is not in use, it automatically drives the lifting block 2 to return to its position, and then drives the stop rod 3 to return to its position, so that the stop rod 3 can be folded up when not in use to save space.

[0034] A stop seat 7 is installed on the frame 1, and there are two of them, which are located on both sides of the frame 1 to stop the vehicle body on the frame 1. The advantage of two is that it is more stable and reliable. The function of the stop seat 7 is to stop the locomotive on the frame 1 when the train is running to increase stability.

[0035] There are also multiple lifting blocks 2, which correspond to multiple stop rods 3 respectively. The advantage of multiple stop rods is that the force is shared to prevent the lifting block 2 from being damaged due to excessive force.
