First, as shown in Figs. 4 and 5, the housing unit 110 is provided to cover the rails R. As shown in Fig.

The housing unit 110 preferably covers the upper surface and both sides of the rail R. The housing unit 110 includes a space that is slidable on both sides and both sides of the rail R .

The housing unit 110 may form the concept of a housing formed integrally with the housing unit 110. However, as shown in FIG. 5, the housing unit 110 may include a side frame 112 or a ceiling frame 111). When the side frames 112 and the sealing frames 111 are provided, the side frames 112 may be worn by the frictional force generated when the housing unit 110 slides in the longitudinal direction of the rail R. [ Or simply by replacing the sealing frame 111, the worn portion can be handled.

The blocking unit 120 is disposed on one side of the housing 110, preferably in contact with the wheel 32 of the tripper 30, so that the blocking of the tripper 30 is directly blocked.

The blocking unit 120 is preferably formed in a vertically standing plate shape as shown in FIGS. 6 and 7, but the blocking unit 120 is not necessarily limited to such a shape.

The blocking unit 120 directly contacts the tripper 30 wheel 32 to prevent rotation of the wheel 32 that rolls on the rail R as shown in FIG. Accordingly, when the blocking unit 120 has a vertical plate shape, it is preferable that the up and down length of the blocking unit 120 is equal to or larger than the radius of the wheel 32, but it is not necessarily larger than the diameter of the wheel 32.

The blocking unit 120 preferably has mechanical strength so as not to be damaged by the collision of the wheel 32 in the configuration in which the collision with the wheel 32 occurs, It is also preferable that heat resistance is provided so that thermal damage does not occur.

A side fastening unit 130 is provided on at least one side or preferably both sides of the housing unit 110 so as to press both sides of the rail R and generate a frictional force so that the housing unit 110 Is fixed on the rail (R) so as not to move.

More specifically, the side fastening unit 130 includes a fastening cam 131; A shaft 132; And a side lever 133. [0034]

5, the fastening cam 131 is disposed apart from the side surface of the rail R, and the pressure applied to the side surface of the rail R is adjusted according to the angle of rotation, that is, do.

As shown in Fig. 5, the fastening cam 131 has an axis connected to a somewhat bowed portion from the center of rotation, similar to a general cam, which is provided with a shaft 132 to rotate the shaft 132 The fastening cam 131 is rotated.

5, when the shortest radius of the fastening cam 131 faces the rail R in accordance with the rotation of the shaft 132, the fastening cam 131 is separated from the side of the rail R And the shaft 132 is slightly rotated so that the middle radius of the fastening cam 131 faces the rail R to press the side surface of the rail R. [ When the shaft 132 further rotates so that the longest radius of the fastening cam 132 faces the rail R, the force that the fastening cam 131 presses the side surface of the rail R reaches the apex.

As shown in FIG. 5, a side lever 133 is provided on one side of the shaft 132, which serves as a knob for a kind of operator. When the side lever 133 is rotated, the shaft 132 rotates, and thereby the pressure that the fastening cam 131 applies to the rail R, that is, a change in the frictional force occurs.

It is preferable that the above-described fastening cam 131 presses the neck portion rather than presses the side of the head portion of the rail R. This is because the wheel 32 is pressed against the rail R to be conveyed, So as to ensure the life of the rail R itself. It is also undesirable to press the head portion of the rail R because there is a risk that the portion to be pressed is peeled off over the rail R. [ Conventional prior art techniques have very disparate effect differences in pressing the head of the rail R and the neck of the rail R because they do not even recognize this problem.

As described above, in the system of the side fastening unit 130, there is a possibility that any rotation of the fastening cam 131 may occur, which means that any movement of the wheel 32 to be blocked is possible. Accordingly, the present invention may further include a fixing unit 150.

As shown in FIGS. 5 and 6, the fixing unit 150 is a kind of safety device that applies a pressing force, that is, a frictional force to the fastening cam 131 to prevent any rotation of the fastening cam 131.

More specifically, the fixing unit 150 includes a fixing screw 151; And a screw handle 152.

The fixing screw 151 is inserted through the side surface of the housing unit 11 so that one end presses one side of the fastening cam 131.

As can be seen from the terminology, the fixing screw 151 is formed with threads on the outer circumferential surface, and one end of the fixing screw 151 presses the fastening cam 131 or the pressurized pressure is released.

The other end of the fixing screw 151 is provided with a screw handle 152. The pressing force applied thereto can be easily adjusted only by the rotation of the naphthene handle 152. [

As shown in FIGS. 4 and 5, the present invention may further comprise a top fastening unit 140 as an auxiliary.

The top fastening unit 140 is provided on the upper portion of the housing unit 110 to press the upper surface of the rail R rather than the side surface thereof to fix the housing unit 110 to the rail R.

To this end, the top fastening unit 140 comprises a pressure pad 141; A screw 142; And a nut ring (143).

First, in the case of the nut ring 143, the nut ring 143 is fixed to the housing unit 110 and is provided at a position above the rail R in the housing unit 110. The nut ring 143 is formed with an opening, which has the same structure as that of a nut in which a thread is formed on the inner peripheral surface of the opening formed. When the nut ring 143 is provided in the housing unit 110, the formed opening is arranged to penetrate up and down.

The screw 142 has a hexagonal bolt or the like formed at the upper end thereof and a pressing pad 141 to be described later is pressed at the lower end thereof.

The screw 142 has a thread formed on the outer circumferential surface thereof and functions to fasten the screw 142 to the inner circumferential surface of the nut ring 143. When the screw 142 rotates, And is vertically conveyed.

A pressing pad 141 is provided below the screw 142. When the screw 142 is conveyed downward, the pressing pad 141 presses the upper surface of the rail R on the lower surface thereof So that the housing unit 110 is fixed to the rail R.

When the screw 142 rotates in the opposite direction, the pressing pad 141 is separated from the upper surface of the rail R, and the frictional force is released.

4, irregularities are formed on the lower surface of the pressing pad 141 to maximize the frictional force applied between the pressing pad 141 and the upper surface of the rail R. [

The housing unit 110 is not lifted from the rail R and is not detached even if the pressing pad 141 presses the upper surface of the rail R. This is because the side fastening unit 130, This is because the fastening cam 131 of the rail R presses the neck of the rail R.
