Description

[0001] POWER RAIL UNIT FOR DRIVING TRANSPORTATION LOGISTICS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power rail unit for driving a goods conveyance device, and more particularly, to a power rail unit for driving a goods conveyance device by safely supplying power to a goods conveyance device such as a crane, a hoist, To a power rail unit for driving a logistics conveying apparatus.

Generally, a power rail is a means for supplying electric power to a load-carrying device such as a crane or a hoist, and is installed on a moving path of the load-carrying device to guide the running of the load. And maintains contact with a conductor mounted inside the power rail to supply power to the goods transporting apparatus.

These power rails are produced by extrusion molding of hard plastic material and have high insulation power. By inserting 7 copper conductors into the power rail, it is possible to prevent safety accidents that may occur in the industrial field.

Meanwhile, the power flowing into the power rail is supplied to the goods conveyance device through the collector, and the lower end of the power rail is opened to a width of about 11 mm so that the collector can be moved. It is sealed by using rubber so that foreign substances can be prevented from entering into the place where the environment is poor (outdoor place, dust, water vapor and vapor).

Generally, the power rails are manufactured to have a length of 4M, and a plurality of the power rails are connected to each other in the field. However, due to the characteristics of the poor places where the power rails are installed, There was a problem. That is, when neighboring power rails do not exactly coincide with each other, collectors moving along the power rails engaged with the power rails are caught by the connecting portions of the power rails, thereby causing safety problems. The cross section of the power rail must be precisely matched and installed in the field. However, in the field where the power rail is installed, since the environment is usually poor, it is difficult to install the power rails adjacent to each other exactly and the installation time is very long There was a problem.

Also, a plurality of copper conductors to be mounted in the power rails are connected to each other or a copper conductor wound in a roll form must be inserted continuously in a very long line. On the condition that the copper conductors are mounted in the power rail, There is a problem that it is very troublesome and takes a long time to connect and insert.

Meanwhile, although the copper conductor is inserted into a conductor coupling groove formed in the power rail, the copper conductor is electrically connected to each other due to an external factor on the condition of a poor industrial field, resulting in electrical short circuit .

FIG. 2 is a perspective view showing a power rail unit for driving a goods conveyance device according to a first embodiment of the present invention Fig. 3 is a view showing a state in which a collector is installed in the power rail unit according to the first embodiment of the present invention. Fig.

1 to 3, the power rail unit for driving the goods conveying apparatus according to the present embodiment may include a rail 110, a pair of sealing members 120, and a connecting means 130.

The rail 110 may be elongated in the form of a square pipe. For example, the rail 110 may be made of a hard plastic insulator. The rail part 110 may have a length of 4 m and may be connected to a required length.

The rail part 110 may include a body part 111, an opening part 112, a guide groove part 113, and a seal fixing groove part 114.

The body part 111 may be elongated in the form of a square pipe. Meanwhile, the upper and lower corners of the body 111 may be rounded. That is, when the two rail parts 110 are connected to each other, a connection cover (not shown) is attached after taping the connection part with an insulating tape (not shown), and both side edges of the upper part of the body part 111 So that the degree of adhesion between the insulating tape and the connecting lid can be greatly improved.

On the other hand, both side portions of the body portion 111 extend in the lower end direction of the opening portion 112 so that the lower end portion can maintain a lower position than the opening portion 112. Both side portions of the body portion 111 extending in the lower end direction of the opening portion 112 flow along the side portion of the body portion 111 and the rainwater located at the end portion of the body portion 111 rises in the opposite direction, So that it is possible to prevent the phenomenon of being inserted into the body part 111 through the opening 112.

Further, a ground line 115 may be further formed on the side surface of the body part 111. [

The opening 112 may be formed on a lower surface of the body part 111 to be penetrated by a current collector 200 that is slidably coupled to the body part 111. [

In addition, the partition wall portion 117 reinforces the rail portion 110 to improve the flexural strength and the impact strength of the rail portion 110.

The pair of sealing members 120 are in close contact with the current collector 200 passing through the opening 112 to prevent foreign substances from entering the inside of the rail 110. [ 114). Here, the sealing member 120 may be made of a soft plastic material.

For example, the sealing member 120 may include an engaging protrusion 121 and a sealing portion 122.

The engaging projection 121 may be resiliently inserted into the sealing fixing groove 114. For example, the engaging protrusions 121 may be formed in the shape of an arrow.

The hermetic portion 122 may extend from the engaging projection 121 to a central portion of the rail portion 110 so as to be inclined downward. That is, when the pair of sealing members 120 are coupled to the sealing fixing grooves 114, the sealing portion 122 may be formed so as to extend from the engaging protrusion 121 to the lower portion of the rail 110, And may be formed so as to be inclined downward toward the center portion side. The lower end of the sealing part 122 is rounded in a streamlined shape so as to smoothly contact with the current collector 200 to minimize wear of the neck of the current collector 200 due to frictional heat, So that the service life of the member 120 can be prolonged.

The sealing member 120 may be formed by easily engaging the engaging protrusion 121 with the sealing fixing groove 114 or by inserting the engaging protrusion 121 inserted into the sealing fixing groove 114 And an elastic space portion 123 formed on the engaging protrusion 121 so as to be easily removed from the sealing fixing groove 114. [

The connecting means 130 may include a pair of rail portions 110 connected to each other when the other rail portion 110 is connected to the rail portion 110 to extend the rail portion 110 Thereby preventing the collector 200, which is slidably moved along the rail 110, from being caught on the connection portion of the rail 110.

For example, the connection means 130 may include a connection groove 131 and a connection pin 132.

At least one pair of the connection groove 131 may be formed in the rail 110. For example, the connection groove 131 may be formed at the upper end of the cross section of the rail 110.

The connection pin 132 may be inserted into the connection groove 131 formed in the rail part 110 to be connected to each other so that the pair of rail parts 110 may be precisely aligned and connected without being stepped.

The connection pin 132 may further include a stopper 133 for preventing insertion of the connection pin 132 into the connection groove 131 by a predetermined depth or more.
