Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine transportation equipment, and particularly relates to an exhaust gas diversion device for a mine-used diesel single-rail hoist locomotive. Background Art

[0002] The single-rail hoist locomotive is the power device for the operation of the single-rail hoist. When the locomotive is going uphill or hoisting heavy objects, a large power demand is required. When the power is increased, it is easy to cause the accumulation of CO, resulting in frequent over-limit detection of CO by the probe, leading to the shutdown of the single-rail hoist and the inability to transport materials normally, affecting the tunneling construction progress of the mining area. Content of the Utility Model

[0003] The purpose of the utility model is to provide an exhaust gas diversion device for a mine-used diesel single-rail hoist locomotive to solve the problem of over-limit shutdown caused by the accumulation of CO at the tail of the single-rail hoist locomotive.

[0004] The technical solution of the utility model is an exhaust gas diversion device for a mine-used diesel single-rail hoist locomotive, which includes a T-shaped shunt pipe and a Z-shaped diversion pipe. The head end of the T-shaped shunt pipe is connected to the exhaust gas discharge port of the single-rail hoist locomotive, and both ends are respectively connected to the Z-shaped diversion pipe. A number of exhaust holes are spacedly arranged on the Z-shaped diversion pipe to disperse and discharge the exhaust gas.

[0005] Preferably, the above exhaust holes are opened at the bottom of the Z-shaped diversion pipe, the distance between adjacent exhaust holes is 60 mm, and the hole diameter is φ20 mm.

[0006] Preferably, 41 exhaust holes are opened on each Z-shaped diversion pipe, and an adjustment valve is installed every other hole.

[0007] Preferably, both the T-shaped shunt pipe and the Z-shaped diversion pipe are made of 160*80 mm square steel.

[0008] Compared with the prior art, the beneficial effect of the utility model is that the T-shaped shunt pipe is connected to the exhaust gas discharge port of the single-rail hoist locomotive, and the exhaust gas is shunted into the Z-shaped diversion pipes on both sides through the T-shaped shunt pipe, and then the exhaust gas is dispersed and discharged through the exhaust holes at the bottom of the Z-shaped diversion pipe, avoiding the frequent over-limit detection of CO by the probe caused by the accumulation of CO, enabling the single-rail hoist to carry out normal transportation operations, avoiding shutdown due to CO over-limit, ensuring that the material supply meets the production requirements of the mining area, and accelerating the tunneling construction progress of the mining area. The locomotive runs normally, avoiding manual material transportation, reducing labor intensity, and saving labor costs. Brief Description of the Drawings

[0011] The following will further explain and illustrate the present utility model in conjunction with the accompanying drawings of the specification, so as to facilitate better understanding by those skilled in the art.

[0012] Embodiment 1

[0013] As Figure 1-2 shown, a tail gas diversion device for a mine-used diesel single-rail hoist locomotive includes a T-shaped shunt pipe 1 and a Z-shaped diversion pipe 2. Both the T-shaped shunt pipe 1 and the Z-shaped diversion pipe 2 are made of 160*80mm square steel. The length of the T-shaped shunt pipe 1 is 500mm, and the length of the Z-shaped diversion pipe 2 is 2700mm. The materials are taken on-site for preparation, which is simple and convenient. The head end of the T-shaped shunt pipe 1 is connected to the tail gas discharge port of the single-rail hoist locomotive, and both ends are respectively connected to the Z-shaped diversion pipe 2. A number of exhaust holes 3 are spacedly arranged on the Z-shaped diversion pipe 2 to disperse and discharge the tail gas.

[0014] Further, the exhaust holes 3 are opened at the bottom of the Z-shaped diversion pipe 2. The distance between adjacent exhaust holes 3 is 60mm, and the hole diameter is φ20mm; 41 exhaust holes 3 are opened on each Z-shaped diversion pipe 2, and a regulating valve 4 is installed every other hole to control the tail gas discharge flow rate.

[0015] The tail gas is shunted into the Z-shaped diversion pipes 2 on both sides through the T-shaped shunt pipe 1, and then the tail gas is dispersed and discharged through the exhaust holes 3 at the bottom of the Z-shaped diversion pipe 2 to avoid the aggregation of CO.

[0016] The above-described embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit and principles of the present utility model, various deformations and improvements made by those skilled in the art to the technical solution of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
