Description

Conductor rail blowing trolley

The present invention relates to a blow-off cart, and more particularly to a conductive rail blow-off cart.

The applicant's factory has a number of independent lanes for high-speed steel coil trolleys. The conductive rails of each lane need to be cleaned regularly to ensure the stability of the equipment operation.

Referring to Figure 1, the conventional method of blowing the conductor rails is to provide a vehicle 110 on the lane that can travel on the two rails 120. A blow tube 130 is also disposed on both sides of the trolley 110, and is opposed to the conductive rails 140 on both sides of the rail 120. When the conductive rail blowing operation is performed, the blow pipe 130 is connected to the pressurized air line, and the trolley 110 is pushed by a person to allow the pressurized air ejected from the blow pipe 130 to blow the conductive rail. In this way, the entire section of the conductive rail 140 can be cleaned by blowing.

Since the applicant's factory has multiple independent lanes for high-speed steel coil trolleys, the tracks on each lane are not connected. To blow the conductive rails on different lanes, it is necessary to manually move the trolley 110 to another lane. However, since the track on the driveway is about two meters wide, the trolley is not only bulky but also heavy, which makes the trolley movement not very easy.

In view of this, there is a need to propose a solution to solve Describe the problem.

The present invention provides a conductive rail blowing cart.

To achieve the above objective, the conductive rail blowing cart of the present invention comprises: a base; at least one first roller disposed on the base, the first roller is used for rolling on a track, wherein the track is disposed at a second roller connected to the base for rolling on the ground on both sides of the track; and at least one blow pipe connected to the base for blowing air.

According to the present invention, the conductive rail blowing trolley is only standing on a single track, and the volume of the blowing trolley is only one quarter of the original, and the weight is also greatly reduced, and it can be easily moved by one person. It is quite light and flexible.

The above and other objects, features, and advantages of the present invention will become more apparent from the accompanying drawings. In the description of the present invention, the same components are denoted by the same reference numerals and will be described.

Referring to Fig. 2, the conductive rail blowing cart 200 of the present invention has a U-shaped base 210 with recesses facing downward. A roller 222 is connected to each side of the base 210. In addition, the base 210 is further provided with at least one roller 224, preferably two rollers 224 arranged in a front-to-back arrangement. At least one detachable connection is connected to the base 210 The blow tube 230 is in communication with a pressurized air line. A horizontal fulcrum roller 240 extends from above the base 210, and the direction of the rolling is perpendicular to the rolling direction of the roller 222. In addition, the base 210 further extends a pair of handles 250 extending in a direction perpendicular to the two phases, wherein the extending direction of the handle 250 is parallel to the direction of the connection of the two rollers 224.

Referring to Fig. 3, when the conductive rail 140 is blown off using the conductive rail blowing cart 200 of the present invention, the recess of the U-shaped base 210 is placed over a single rail 120, that is, the upper surface of the rail 120 is Both sides are received in the recess of the U-shaped base 210, at which time the two rollers 222 will be positioned on the ground on either side of the track 120, while the roller 224 is positioned on the track 120. The horizontal fulcrum roller 240 is inserted into one of the conductive rails 140 as a horizontal support point for the blown cart 200. In addition, the position of the blow tube 230 is adjusted to be aligned with the conductive rail 140, and pressurized air is introduced into the pressurized air line from the joint 260 so that the pressurized air can be ejected from the blow tube 230.

During the blowing operation, the personnel hold each hand 250 with both hands and push the cleaning cart 200, wherein the extending direction of the one hand 250 is parallel to the traveling direction of the base 210 on the rail 120. While the blower cart 200 is moving, the rollers 222 will roll on the ground on either side of the track 120, the rollers 224 will roll on the track 120, and the horizontal fulcrum rollers 240 will roll within the conductive track 140. The function of the horizontal fulcrum roller 240 is to serve as the level of the blow-up cart 200 The support points are such that the blow-up cart 200 does not sway when moved so that the blow tube 230 can be aligned with the conductive rails 140. In order for the horizontal fulcrum roller 240 to not damage the conductive rail 140 when it is rolled, the horizontal fulcrum roller 240 is preferably made of a material that is not rigid, such as rubber or bakelite.

When the conductive rails 200 are blown using the conductive rail of the present invention to blow the conductive rails 140, when the blown cart 200 is smoothly stood on the rails 120, the two sides of the recesses of the U-shaped base 210 are tied to the rails. The sides of 120 are about 0.5 cm apart. When the cart is not stable and tilted, the blow tube 230 will not be able to perform the blow clearing operation for the conductive rail 140. At this time, the two sides of the recess of the U-shaped base 210 will rub against the rail 120 to cause the cart to advance. Resistance, therefore, can alert the operator that the position of the blow tube 230 has deviated.

According to the present invention, the conductive rail blowing trolley is only standing on a single track, and the volume of the blowing trolley is only one quarter of the original, and the weight is also greatly reduced, and it can be easily moved by one person. It is quite light and flexible.

While the present invention has been disclosed by the foregoing examples, it is not intended to be construed as limiting the scope of the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
