Embodiment 1

[0026] Such as Figure 1-2 As shown, the narrow-gauge mine car maintenance device in this embodiment includes a support frame, and a rope tightening device is arranged on the support frame, and a lifting rope 1 is wound on the rope tightening device; the lifting rope 1 is connected to There is a connecting piece 2 for connecting with said narrow gauge mine car 8 .

[0027] In this embodiment, the support frame includes a base 3 and a vertical frame disposed above the base 3, and the rope tightening device is disposed on the top of the vertical frame. Wherein, the vertical frame includes two uprights 4 , and the lower ends of the two uprights 4 are fixed on the base 3 . A beam 5 is arranged between the top ends of the two columns 4 , and the rope tightening device is arranged on the beam 5 . In this embodiment, the base 3 is a steel plate, which plays the role of supporting the overall framework and stabilizing device of this embodiment. In order to ensure the strength and s...

Embodiment 2

[0042] see image 3 , the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, in this embodiment, a reinforcing rib 10 is provided between the column 4 and the base 3 . The rib plate 10 can improve the fixing strength between the column 4 and the base 3, and improve the firmness of the device. Avoid the separation of the column 4 from the base plate due to excessive force during the lifting of the mine car 8 .

[0043] Two reinforcing ribs 10 can be provided on both sides of the column 4; more reinforcing ribs 10 can also be provided, such as four, evenly distributed around the column 4, which can better improve the relationship between the column 4 and the base 3. Connection strength in different directions.

[0044] The usage method of this embodiment is the same as that of Embodiment 1, and reference can be made to the introduction about the usage method in Embodiment 1.

Abstract

The invention provides a maintenance device of a narrow-gauge mine car. The maintenance device comprises a support frame, wherein a rope tightening device is arranged on the support frame, a hoistingrope is wound around the rope tightening device, and the hoisting rope is connected with a connecting piece used for being connected with the narrow-gauge mine car. The maintenance device has the characteristics of strong practicability, good applicability, simple and reliable operation, and the like; in particular, the device is light and can be moved to a required position by a single person; overturn of the whole mine car to be maintained can be realized; it is not needed to turn over the whole mine car through an original method by using a crowbar through two persons; and the mine car weighing about one ton can be turned over by 90 degrees to one side of a track through single-person operation, so that the working efficiency and the safety and reliability of the mine car maintenance are improved.

Description

technical field [0001] The invention relates to the technical field of maintenance and repair application equipment for narrow-gauge mining vehicles, in particular to a maintenance device for narrow-gauge mining vehicles. Background technique [0002] Narrow-gauge mine cars are widely used as a carrier for transporting minerals in small and medium-sized coal mines or non-coal mines. Narrow-gauge mining vehicles have the characteristics of high flexibility and good reliability in transporting ore. However, due to the high frequency of use of mining vehicles in mine production, the repair and maintenance workload of mining vehicles in various mines is also relatively large. Small mining vehicles (carriage volume ≤1.1m 3 ) has a self-weight of nearly one ton, and the labor intensity of maintenance personnel is high. [0003] The prior art of narrow-gauge mine car maintenance mainly contains two kinds of modes. The first is the traditional human crowbar overturning scheme; th...
