[0002] At present, my country is the world's largest producer and consumer of calcium carbide, and the calcium carbide industry is developing rapidly. However, as an important equipment in the field of calcium carbide production technology, the transportation system of the calcium carbide furnace trolley has many problems.

[0003] The transportation system of the trolley for calcium carbide furnace out of the furnace is mainly composed of a winch, a traction wire rope, a track, a ground roller, etc., among which the ground roller is located in the middle of the track. However, due to the gap between the two ends of the ground roller and the track, the wire rope often deviates from the ground roller and falls into the gap, which makes the wire rope easy to cause serious friction or jamming. Over time, the wire rope may break, causing the calcium carbide pot to fall off the track, which increases the workload of on-site personnel and brings many safety hazards. Utility model content:

[0004] The utility model aims to provide a device for preventing a steel wire rope from running off track for a calcium carbide furnace, so as to solve the problems raised in the above-mentioned background technology.

[0006] A device for preventing a steel wire rope from running off track for a calcium carbide furnace comprises two rails arranged parallel to the ground, a support seat, a stepped shaft, a cylindrical roller bearing, a cylinder, a round rod, a buffer spring and a limit sleeve; grooves are provided at the bottoms of the inner surfaces of the two rails that are opposite to each other, a support seat is fixedly arranged in the groove, a stepped shaft is fixedly connected between the two support seats, two cylindrical roller bearings are symmetrically fixedly sleeved on the stepped shaft, and a cylinder is fixedly sleeved on the outer ring surfaces of the two cylindrical roller bearings; at least one limit assembly is distributed between the two rails; the limit assembly comprises: a round rod fixedly connected between the two rails, two buffer springs and a limit sleeve are sleeved on the round rod, and the limit sleeve is arranged between the two buffer springs.

[0007] Preferably, the inner surface of the track is in contact with the outer surface of the support seat.

[0008] Preferably, both ends of the cylinder are in a "cone" structure, and the two end surfaces of the cylinder are in contact with the opposite inner surfaces of the two support seats.

[0009] Preferably, the limiting sleeve is in an "H" structure, and the limiting sleeve is formed as one piece by welding two flanges relative to each other.

[0010] Preferably, one end of the buffer spring abuts against the inner surface of the track, and the other end of the buffer spring abuts against the outer end surface of the limiting sleeve.

[0011] The advantages of the utility model are as follows: by reducing the gap between the two end surfaces of the ground roller and the inner surface of the track, the problem of the wire rope getting stuck after deviating is solved; at the same time, the inner surfaces at both ends of the limiting sleeve on the limiting assembly are used to limit and intercept the wire rope, preventing the wire rope from deviating from the middle of the cylinder, and under the action of two buffer springs, the limiting sleeve is prevented from hard surface contact with the surface of the wire rope, causing serious wear, ensuring that the limiting sleeve is in the middle of the two tracks, correcting the position of the wire rope, and improving the safety of the production process.

[0021] The two ends of the cylinder 5 are in a "conical" structure, and the two end faces of the cylinder 5 are in contact with the inner surfaces of the two supporting seats 2. The purpose is to utilize the fitting relationship between the two end faces of the ground roller and the inner surface of the track in the absence of a limiting component to avoid the problem of the wire rope 9 getting stuck after deviation, thereby extending the service life of the wire rope 9 and improving safety.
