Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a transfer device for moving a device or the like in a straight or backward direction. .

[0002]

[Prior art]

  For example, long pipes such as electric resistance welded pipes are inspected for their inner surface after manufacturing and added if necessary. It is necessary to perform maintenance. In this case, the required equipment is moved along the entire length of the pipe. The so-called push-in / pull-out operation is performed. A bar jig comparable to the target pipe length was used.

[0003]

[Problems to be solved by the device]

  However, in the operating means using the rod-shaped jig as described above, It requires an operation space to insert it inside and pull it out of the pipe, and it can be used as a valuable factory site. There was a problem of occupying.

[0004]   The present invention has been made to solve such a problem, and it is better than the target pipe length. Can be installed in a much shorter site space, and surely achieves the intended purpose. It is an object of the present invention to provide a transfer device that can be formed.

[0005]

[Means for Solving the Problems]

  In order to achieve the above-mentioned object, the transfer device according to the present invention is configured to be phase-bonded on the back surface of the node. Both chains are equipped with a pair of chains equipped with engaging members to prevent bending in the opposite direction. The chain is connected at the tip and connected to the equipment, and one chain is connected at the rear. A drive sprocket that engages with the sprocket is provided. A chain that joins and separates both chains to store the separated chains. It is equipped with a guide and controls the equipment connected to the ends of both chains. ・ Cable for operation ・ Air hose support is provided on either chain Of.

[0006]

[Action]

  In the transfer device of the present invention having the above-described structure, both chains are driven by driving the sprocket. Moves back and forth as a unit, starting from the outer peripheral required position of the sprocket Let go. The joined chains move back and forth as a rigid rod, allowing devices to be Push and pull. Separated chains are each shaped as a chain guide. The shape of the chain guide is selected according to the shape of the device. The installation space can be reduced.

【Example】

  The present invention will be described below based on an embodiment shown in FIGS.   FIG. 1 is an overall front view showing an embodiment of the present invention, and FIG. 2 shows one chain, (a) is a front view, (b) is a bottom view, FIG. 3 shows the other chain, and (a) is a front view. , (B) is a bottom view, FIG. 4 (a) is a sectional view taken along line AA of FIG. 2 (b), and (b) is FIG. 3 (a). ) BB cross-sectional view, FIG. 5 (a) ~ (d) is a front view showing the joining and separating operation of the chain It is a figure.

[0008]   1 to 5, reference numerals 1 and 2 are chains that face each other (hereinafter, "1 One chain, the other chain is referred to as "the other chain", and they are connected together by the connecting pin 3. And a roll 3a is loosely fitted to the outer end of the pin 3, respectively. Has been.

[0009]   Further, engaging members 4 are provided on the back surfaces of both chains 1 and 2, and these engaging members 4 are When the chains 1 and 2 are joined, they are superposed and engaged at their respective nodes, It is configured so as to prevent bending of 1 and 2 in opposite directions. And an example The engaging member 4 in is a U-shaped or L-shaped unit that constitutes the chains 1 and 2. It is constructed by folding it in.

[0010]   The both chains 1 and 2 have a male and female coupling structure at their ends, and the pins 5a and 5b are This is what is connected to a device, etc., and the substantial coupling of both chains 1 and 2 is Only the portion of the pin 5a.

[0011]   6 is the front end position of the back surface of the other chain 2, for example, at intervals of every other single unit. It is a hook piece provided, and the position where the engaging member 4 on the back surface of the one chain 1 side faces A slit 7 into which the hook piece 6 is fitted is provided in the. That is, the hook piece 6 and the pickpocket When the chains 1 and 2 are joined, the hood 7 maintains the integral joining rigidity of the two. It is a fixing means for, and its configuration, installation interval, etc. are not specified.

[0012]   Reference numeral 8 denotes a sprocket that is engaged with one of the chains 1 and transmits a driving force to the chain 1. , Joining and separating both chains 1 and 2 from the required position on the outer periphery of the sprocket 8 as a starting point. Separate and store the separated chains 1 and 2 in the narrow space as limited as possible. The chain guides 9 and 10 are provided for this purpose.

[0013]   That is, the chain guide 9 that holds one of the chains 1 is It is curved along the outer half of No. 8 and is extended further forward so that The chain guide 10 that guides one chain 1 and retains the other chain 2 is Extends horizontally further from the joining / separation starting point of chains 1 and 2 and pushes equipment such as a The inner rail 10a that guides the other chain 2 at the time of construction and the connection of the chains 1 and 2 At the time of pulling operation of equipment, etc. with the joining / separation starting point as the base end and facing the rail 10a. The outer rail 10b that guides the other chain 2 to the chain Like the main guide 9, it is greatly curved and extends forward. The chain One of the parts of the guide 10 facing the inner extension of the inner rail 10a An auxiliary rail 11 is provided to guide the chain 1 when the chain 1 is pushed.

[0014]   By the way, as shown in FIG. 4, the width of the link plates constituting the chains 1 and 2 is By making it wider, as shown in FIG. A space for inserting and supporting the air hose 12 is formed.

[0015]   As described above, the present invention has a structure in which the chains 1 and 2 prevent the opposite bending in both directions. Moreover, one chain 1 is provided with a hook piece 6 for attracting the other chain 2. , The other chain 2 is provided with a slit 7 for receiving the hook piece 6 to form a pair of both. At the starting point of the required position on the outer peripheral portion of the drive sprocket 8, the two chains 1 and 2 are connected. Together to maintain a stronger rigidity and straightness to secure pushing force. At the time of reverse feeding, separate the chains 1 and 2 at the starting point and send each to the storage space The above operation is performed by the forward and reverse rotation of the drive sprocket 8. As a result, the insertion / movement / drawing of the device (a) into the long tube is achieved.

[0016]

[Effect of device]

  As described above, according to the present invention, two devices that are connected at the tip and have a reverse bending prevention mechanism are provided. Set a chain as a pair and start from the required position on the outer periphery of the sprocket that drives this chain. The two chains are joined or separated and the separated chains are each stored in the storage space. It is equipped with an internal chain guide and is shorter than the target pipe length for inspection, etc. It can be installed in the site space. In addition, it is directly connected to equipment etc. and moves forward and backward. The two chains that are joined and integrated to transmit power are kept rigid and straight. Therefore, it exerts a reliable action and achieves the intended purpose.
