Description

Technical Field

[0001] The utility model belongs to the technical field of railway rescue, in particular to a device for straightening and lifting wheels of a train after it tilts. Background Art

[0002] Trains, also known as railway trains, refer to vehicles running on railway tracks, usually composed of multiple carriages. They are one of the important modern means of transportation for humans. Derailment may occur during the running of trains. In order to rescue derailed trains in a timely manner, a large number of rescue equipment will be used. Among them, the jacking wheel device is one of the most common train rescue tools. The jacking wheel device is generally called a rerailer, which is mainly used to help the train to straighten and realize the rerailing of the train;

[0003] The existing document with publication number CN210234982U discloses a hydraulic rerailer, including a hanger for fixing the beam of a derailed vehicle, two hydraulic cylinders hinged on both sides of the hanger to provide lifting force and translation force and arranged in a herringbone shape, and a fixing seat hinged to the bottom end of the hydraulic cylinder for fixing, the hanger includes a support rod with two ends hinged to the top of the two hydraulic cylinders for supporting function and a hanger hinged to the bottom of the support rod through a hinged rod and a through groove arranged in the middle, the hinged rod is provided with two and the two ends are hinged to the two ends of the hanger and the support rod respectively, and the two ends of the bottom of the groove on the hanger are respectively provided with a hook ring and a rope;

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The hydraulic rerailer mentioned above has a lifting device including a supporting rod and a lifting seat, and hooks and ropes are respectively provided at both ends of the bottom of the lifting seat. The lifting device is connected to the train through the hooks and ropes, so as to ensure that the hydraulic cylinder can lift and straighten the train. However, the setting of the hooks and ropes leads to rapid loading and unloading between the lifting device and the train, which increases the workload of the staff and has low work efficiency.

[0006] 2. The hydraulic rerailer in the above-mentioned method has a sling hinged on the top of its two hydraulic cylinders, and a fixed seat hinged on the bottom of the hydraulic cylinder. The derailed train is fixed by the sling, and the hydraulic cylinder is used to provide lifting force and translational force to the derailed train, and the hydraulic cylinder is fixed by the fixed seat. It lacks a positioning structure, which requires the staff to observe whether the train is straightened by the naked eye, which has poor accuracy and also increases the workload of the staff.

[0007] For this reason, we provide a train tilting rear straightening and top wheel device to solve the above-mentioned problems. Utility Model Content

[0040] Specifically, the bidirectional screw rod 201 is connected to the inner side of the crossbeam 1 along the transverse rotation, and the moving rod 202 is threadedly sleeved on both sides of the outer wall of the bidirectional screw rod 201. The outer wall of the bidirectional screw rod 201 is respectively provided with left-handed and right-handed threads on both sides. When the bidirectional screw rod 201 rotates forward, it drives the moving rod 202 to move backwards, and when the bidirectional screw rod 201 is reversed, it drives the moving rod 202 to move towards each other. One end of the moving rod 202 passes through the two ends of the crossbeam 1 and is welded with a side plate 203. The side plate 203 is rotatably connected to a clamping plate 204 at the center position of the outer wall of one side away from the moving rod 202, and an electromagnet 205 is fixedly connected to the outer wall of one side of the clamping plate 204. The setting of the side plate 203 is used to install the clamping plate 204, and the two sides of the train chassis are clamped by the setting of the clamping plate 204. At the same time, the magnetic field generated after the electromagnet 205 is energized will firmly adsorb the clamping plate 204 on both sides of the train chassis.

[0041] Furthermore, the inner sides of the crossbeam 1 are fixedly connected with bearing seats 201a, and both ends of the bidirectional screw rod 201 rotate through the bearing seats 201a. The setting of the bearing seats 201a is used to install the bidirectional screw rod 201;

One end of the baffle 206 away from the mounting rod 206a is clearance-fitted on the inner side of the L-shaped seat 206b. The rotation of the clamping plate 204 is limited by the setting of the baffle 206. The setting of the mounting rod 206a and the fastening nut 206c realizes the rotatable installation of the baffle 206 on the side plate 203. The setting of the L-shaped seat 206b is used to limit the rotation of the baffle 206, thereby fixing the baffle 206.

[0045] The operation process of this embodiment is as follows: first, the crossbeam 1 is placed on the train chassis, and the first knob 201d is turned.

When the card plate 204 moves to both sides of the train chassis, the first knob 201d stops rotating. Knob 201d, then rotate the card plate 204, so that the side of the card plate 204 equipped with the electromagnet 205 is respectively in contact with the two sides of the train chassis, and the electromagnet 205 is energized, so that the card plate 204 is adsorbed on both sides of the train chassis through the magnetic field generated by the electromagnet 205 after being energized, thereby completing the fixation of the train, and finally separate the fixing seat 4, and install the bottom end of the hydraulic cylinder 3 through the fixing seat 4, and at the same time provide liquid to the hydraulic cylinder 3 through the hydraulic station, so that the hydraulic cylinder 3 drives the crossbeam 1 and the train to lift and move, completing the straightening of the train.
