Description

Technical Field

[0001] The utility model belongs to the technical field of equipment related to train rescue, in particular to a suspension wheel device for train rescue. Background Art

[0002] During the operation of locomotives, the reliability of the running gear is of vital importance. Once a wheel pair fails, the locomotive cannot operate normally. In order to maintain the order of locomotive operation and save rescue time, when a wheel pair of a locomotive fails, a rescue suspension wheel device is used to replace the faulty wheel and transport the locomotive to a designated location for maintenance work to reduce the loss caused by the failure.

[0003] However, the existing wheel suspension device does not have the function of controlling the temperature of the wheel group position of the wheel suspension device when in use. Therefore, when the wheel suspension device is running at high speed, the surface of the wheel group is prone to high temperature, which is easy to cause damage. At the same time, when the wheel suspension device is used, it is not capable of limiting the position of the device, so the device is prone to position deviation. To this end, we provide a train rescue wheel suspension device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a wheel suspension device for train rescue, which limits the temperature sensor and the nozzle on the surface of the wheel set through an arc plate, so as to achieve temperature control of the wheel set, and at the same time, the combined rod and the sleeve are used in coordination to limit the distance of the support frame, so as to ensure the stable sliding of the wheel set on the rail.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a wheel suspension device for train rescue, comprising a support plate; two support plates are symmetrically arranged front and back to form a support plate frame, wheel groups are spirally arranged on both ends of the support plate frame, two wheel support cylinders which are symmetrical on the left and right are arranged on the inner side of the support plate frame between the two wheel groups, combination rods are arranged on the left and right parts between the two support plates in the front and back directions, sleeves which are connected with support plate bolts are arranged on the front and rear ends of the combination rods, cooling boxes are arranged on the left and right ends of the two support plates, arc plates are fixed on the end faces of the cooling boxes relative to the wheel groups, a square opening is opened in the middle of the arc plate, a nozzle which is connected with the inside of the cooling box is arranged on the inner side of the square opening, a temperature sensor is fixed on the side wall of the arc plate above the nozzle, and an alarm which is electrically connected with the temperature sensor is fixed on the upper end face of the cooling box.

[0007] The utility model is further configured that a rotation hole is opened at a position of the support plate corresponding to the support roller cylinder, and a T-shaped rod passing through the rotation hole and the inner position of the support roller cylinder is arranged at one end of the support plate.

[0008] The utility model is further configured that the diameter of the end of the T-shaped rod is larger than the hole diameter of the rotating hole, the end of the T-shaped rod passing through the rotating hole is fixed with a screw rod, and the circumferential side of the screw rod is spirally sleeved with a nut.

[0009] The utility model is further configured that through holes are provided on the side walls of the support plate between the two rotating holes, and fastening bolts are provided inside the through holes.

[0010] The utility model is further configured such that mounting strips are fixed to the front and rear end surfaces of the cooling box, and the other end of each mounting strip is respectively bolted to the end surface of the support plate which is in the same position as the mounting strip.

[0011] The utility model is further configured that the end surface of the cooling box opposite to the supporting plate is fixed with a water injection pipe connected with the interior thereof.

[0012] The utility model is further configured that a screw barrel connected to the inside of the sleeve is fixed at the middle position of the circumference of the sleeve, and a locking hole consistent with the upper and lower positions of the screw barrel is opened at the end of the combination rod inside the sleeve.

[0014] The utility model has the following beneficial effects:

[0015] 1. When the utility model is in use, the wheelset travels at a high altitude on the rails, thereby monitoring the temperature of the wheelet surface in real time through the temperature sensor. When the temperature of the wheelet surface exceeds the threshold set by the temperature sensor, the temperature sensor transmits a signal to the alarm, and the alarm sounds. At the same time, the water pump inside the cooling box works to spray the cooling box from the position of the nozzle, thereby cooling the surface of the wheelset to ensure the service life of the wheelset.
