Description

Technical Field

[0001] The invention relates to the field of locomotive maintenance equipment, in particular to a method and a disassembly tool for window glass of an electric locomotive. Background Art

[0002] The front window glass of electric locomotives needs to be replaced or repaired regularly due to long-term use or accidental damage. Especially when the locomotive enters the overhaul stage, some large equipment needs to be removed from the position of the front window glass, and almost all front window glass needs to be removed from the vehicle for inspection or replacement. The traditional disassembly method usually relies on manual labor. The operator uses a step ladder or an elevator to stand on the outside of the locomotive, in front of the front window glass, and uses manual tools (such as wallpaper knives, cutting knives, etc.) to remove the adhesive between the glass and the body mounting frame, so that the glass is separated from the body mounting frame, and then the glass is disassembled through the collaboration of multiple people on both sides. The disadvantage is that it relies too much on manual tools and multi-person collaboration, which is time-consuming and labor-intensive. Not only is the glass easily damaged during the disassembly process due to differences in the skill level of the operators (the glass cannot be used again after partial damage), but there are also safety hazards because the operators need to be in a state of climbing for a long time.

[0020] The present invention provides a method for disassembling window glass of an electric locomotive, comprising the following steps: (i) using a wallpaper knife or a cutting knife to cut off a part of adhesive connecting the glass and a vehicle body mounting frame in advance to form a reserved gap; (ii) using a strip-shaped metal cutting tool to pass through the reserved gap in step (i) and moving the cutting tool back and forth to cut the adhesive, while moving the cutting tool horizontally until all the adhesive around the glass is cut; and (iii) using a lifting tool to move the glass out of the vehicle window.

[0021] like Figure 1 , Figure 3 As shown, the present invention also provides an electric locomotive window glass removal tool, comprising two brackets 1, the bracket 1 comprising a bottom mounting beam 1-1, a middle mounting beam 1-2 and a lead screw 1-3 which are arranged between two side plates and are parallel from bottom to top;

[0022] Two groups of suction cup units 2 are connected to the bottom mounting beam 1-1. The suction cup unit 2 includes a fixed clamping plate 2-1, an L-shaped connecting rod 2-2 and a suction cup 2-3. The fixed clamping plate 2-1 is connected to the bottom mounting beam 1-1 by bolts. The upper end of the L-shaped connecting rod 2-2 is fixed to the fixed clamping plate 2-1, and the lower end is connected to the suction cup 2-3.

[0023] The middle mounting beam 1-2 is located between the lead screw 1-3 and the bottom mounting beam 1-1, and a guide long hole is provided on the length surface of the middle mounting beam 1-2;

[0024] One end of the lead screw 1-3 is rotatably connected to a side plate of the bracket 1, and a group of wire cutting units 3 are connected to the lead screw 1-3. The wire cutting unit 3 includes a lead screw motor 1-4, a slider 3-3, a connecting rod 3-4, a pulley motor 3-1 and a pulley 3-2. The lead screw motor 1-4 is fixed to the bracket 1, and the other end of the lead screw 1-3 is connected to the output shaft of the lead screw motor 1-4. The slider 3-3 is sleeved on the lead screw 1-4, and the slider 3-3 has a threaded hole adapted to the lead screw 1-3. The upper end of the connecting rod 3-4 is fixed to the bottom of the slider 3-3, and the connecting rod 3-4 passes through the guide long hole of the middle mounting beam 1-2. The pulley motor 3-1 is connected to the connecting rod 3-4, and the central axis of the pulley 3-2 is connected to the output shaft of the pulley motor 3-1. The outer periphery of the pulley 3-2 has an annular groove;

[0025] The pulleys on the two brackets 1 are connected by a steel wire 3-5, and the steel wire 3-5 is wound in the annular groove on the pulley 3-2.

[0026] In order to make the contact area between the steel wire 3-5 and the rubber strip smaller and the cutting more sharp, the surface of the steel wire 3-5 has strip-shaped ridges, and metal protrusions with sharp corners can also be welded on the surface of the steel wire 3-5.

[0027] A lifting ring (not shown) for lifting is provided on the bracket 1 or the L-shaped connecting rod 2-2.

[0028] When the above structure is used, the working space is first pre-processed to create space for the cutting wire 3-5 to pass through the glass bonding place. A wallpaper knife or a cutting knife is used to cut off part of the adhesive (strip) connecting the glass and the vehicle body mounting frame to form a reserved gap, such as Figure 2As shown, two brackets 1 are fixed to the inner and outer surfaces of the glass with the cut window by suction cups 2-3 respectively, so that the suction cups 2-3 are adsorbed on the glass surface. At this time, the suction cups 2-3 on the two brackets 1 are arranged opposite to each other, and the wire cutting units 3 on the two brackets 1 are located on the same side of the lead screw 1-3. The pulleys 3-2 at the lower part of the wire cutting units 3 are located at the reserved holes. The cutting wire 3-5 is passed through the reserved holes and installed in the annular grooves of the two pulleys 3-2. The power button is turned on to make the two brackets 1 The two screw motors 1-4 rotate synchronously, the two pulley motors 3-1 rotate synchronously, and the cutting wire 3-5 cuts the adhesive (i.e., the rubber strip) longitudinally under the drive of the pulley motor 3-1, and moves horizontally under the drive of the screw motor 1-4, and the adhesive connecting the glass window 4 and the mounting frame of the vehicle body 6 is cut; after the peripheral adhesive of the vehicle window glass 4 is cut according to the above steps, the unloaded glass can be connected to the above-mentioned tooling through the lifting ring and lifted off the vehicle by an overhead crane, and properly placed in the designated position.

[0029] The bonding position of locomotive windows and window frames is usually closely connected to the steel structure on the locomotive, especially Figure 4 As shown, when cutting the adhesive in the installation groove arranged near the corner of the glass, the cutting tool is easy to touch the steel structure around the adhesive during cutting, thereby causing damage to the surface of the locomotive. The cutting member of the present invention adopts a flexible cutting form of a steel wire 3-5 combined with a pulley 3-2 structure with an annular groove, which can minimize damage to the steel structure around the adhesive.

[0030] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
