Technical Field

The invention relates to a mining device, in particular to a sanding device for a mining electric locomotive.

Background

The sanding device for the mining storage battery electric locomotive increases the friction coefficient between the wheels and the track through sanding, prevents the wheel set from slipping, improves the traction force and the braking force, and ensures the driving safety of a train. In the prior art, a pair of sand boxes are respectively arranged at the bottom of a driver control chamber, a pedal is arranged at the bottom of the control chamber and used for controlling sand spreading, when a locomotive brakes, a driver firstly treads the pedal to enable a sand guide pipe to face a rail surface to form sand spreading, and meanwhile, the locomotive brakes are implemented. This structural form has the following disadvantages in practical use:

firstly, because the sand box is placed in the bottom of controlling the room, in the use, extremely be unfavorable for the driver to observe the condition of spilling sand, fail in time to discover the condition of no sand leakage or lack sand, all are the potential safety hazard.

Secondly, because the sand box and the pedals are arranged at the bottom of the control chamber, the sand box is low in position, sand in the sand box is easily affected with damp, and the damp sand cannot be evenly spread or smoothly spread; the transmission part that is driven by pedal is because of the position is low, often takes place because of the condition of the corrosion of weing, especially in plum rain season, and humidity is great in the pit, and the problem of weing has increased and has controlled the degree of difficulty, has more increased insecurity.

Thirdly, because the sand box is placed at the bottom of the control room, the sand adding is inconvenient in the using process, and the cleaning of the sand barrel and the maintenance of the sand spreading device are inconvenient.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides the sanding device of the electric locomotive, so that the sanding process of the mining electric locomotive can be smoothly carried out, the production safety is ensured, and the convenience degree of operation and maintenance is improved.

the sanding device of the electric locomotive has the structural characteristics that: in an operation room of the mining electric locomotive, a sand box is fixed above the side inside the operation room and is positioned at a position convenient for a driver to observe and operate; a manual gate plate is arranged on the outlet of the sand box, and the outlet of the sand box can be opened or closed by controlling the manual gate plate through a handle; the outlet pipe of manual flashboard is connected with left way sand pipe and right way sand pipe in parallel, left way sand pipe and right way sand pipe downwardly extending and run through respectively and set up the tube-through hole on controlling the room bottom plate, make the end opening of left way sand pipe and right way sand pipe divide and locate the dead ahead at a pair of wheels of mining electric locomotive to the branch is directly over a pair of track, make the end opening of left way sand pipe and right way sand pipe can be towards the track surface sanding of the one side of place separately one-to-one.

The sanding device of the electric locomotive is also structurally characterized in that: the sand box is suspended below a ceiling of the mining electric locomotive by using a bracket.

The sanding device of the electric locomotive is also structurally characterized in that: and a sand twisting shaft is arranged in the sand box, the sand twisting shaft is connected with the manual gate plate, and a handle connected to the manual gate plate extends out of the sand box.

The sanding device of the electric locomotive is also structurally characterized in that: a pair of sand twisting shafts are arranged on the manual gate in a V shape, so that each sand twisting shaft and the vertical handle form a crank arm form.

The sanding device of the electric locomotive is also structurally characterized in that: set up the observation hole on the control chamber bottom plate, the driver observes the condition of left side way sand pipe and right side way sand pipe on the track surface sanding through the observation hole.

Compared with the prior art, the invention has the beneficial effects that:

1. the invention adopts the structural form of the top sand box, and is convenient for a driver to observe the sand box at any time and find the condition of no sand leakage or lack of sand in time in the using process;

2. the sand box is arranged on top, so that the sand can be effectively prevented from being affected with damp, the smooth sand discharging and the uniform sand spreading of the dried sand are kept;

3. according to the invention, the manual gate plate is arranged on the sand box outlet at the bottom of the sand box, namely the manual gate plate is also arranged at the top, so that the drying is kept, the damp is avoided, the operation and the control are reliable, and the safety is improved.

4. The top-mounted structure is convenient for adding sand and cleaning and maintaining the sand box.
