The invention relates to construction, and in particular, to devices for removing developed soil from the face during trenchless laying of underground utilities, but can also be used in other areas of the national economy, in all cases when the transportation of goods requires the transfer of a cable of hoisting-and-transport equipment ,

Known devices for trenchless laying of pipelines, including a transporting scoop, a cable stored through a block mounted on the cutting head of a trenchless laying machine, and a pull winch (ed. St. USSR No. 1051182 and No. 960394, class E 02 F 5 / 18, 1982).

However, to install the next pipe to be laid, it is necessary either to unload the cargo cable of the scoop from the block mounted on the cutting head, or move the towing winch together with the cable inside the laid pipe. This winch is large-sized, mounted permanently. Carrying it would be very time consuming or even impossible if its dimensions would not allow it to be installed in the laid pipe. Therefore, it is necessary to carry out the unpacking of the cargo cable. This operation in the prototype is carried out manually, it is very time-consuming and causes a large overhead, because during the sinking process, it is made repeatedly.

The purpose of the invention is to reduce the complexity of unpacking a freight cable when building up a laid pipeline.

This goal is achieved in that the device for trenchless laying of pipelines, including a scoop, cables, pull winch, further comprises a portable winch with a cable provided at the end with a connecting device made in the form of a flexible element and a clamp.

The proposed technical solution contains new features: the presence of an additional winch with a cable equipped with a connecting element, which ensure the achievement of a positive effect, therefore, it has novelty. As a result of the search, no technical solutions were found containing features similar to the distinguishing features of the proposed solution, which allows us to conclude that the invention meets the criterion of significant differences.

In FIG. 1 shows a device in the process of unpacking a scoop cable and storing an auxiliary cable; figure 2 is the same with

a stored auxiliary cable in the process of building up the laid pipeline; nafig. Z-also, in stocking the scoop cable after joining the pipes; on the

figure 4 - node I in figure 1; figure 5 - connecting device in a perspective view.

A device for trenchless laying of pipelines contains a scoop 1, a cargo cable 2 and a powerful pull winch

3. When feeding the scoop 1 to the bottom and the bottom during the sinking, the cable 2 is stored through the block 4, mounted on the cutting head 5 of the installation for trenchless laying of pipelines installed in the first

the pipe being laid 6. The device comprises a small-sized winch 7 with a cable 8 of small diameter. The winch 7 is made portable or with a removable portable drum. At the end of the cable 8 there is

a connecting device 9, including a flexible element 10, forming a loop 11, and a clamp 12. The flexible element 10 can be attached to the end of the cable 8 by any known method, for example, woven,

moreover, its ends are pre-missed in the holes 13 in the jaws of the clamp 12. As the flexible element 10, the end of the cable 8 itself can be used, from which the loop 11 is formed. The clamp 12 is provided with a fastener, for example a screw 14. The installation for trenchless laying of pipelines also a guide 15 for laying the next pipe to be laid 16.

The device operates as follows.

At the beginning of the driving, the cable 2 from the winch drum 3 is reserved through block 4, and the end

it is connected to the scoop 1 and the scoop is fed into the bottom and out of the bottom into the foundation pit using the pulling winch. Before laying the next pipe 16 to be laid on the guide 15, it is necessary to unfasten the cable 2 from block 4. Disconnect the cable 2 from the scoop 1 make a loop 11 from the flexible element 10 of the cable 8, put the loop 11 and the clip 12 on the end of the cable 2 and tighten it with the screw 14. Turn on the winch 3 (the direction of rotation n is shown by the arrow in Fig. 1), the cargo cable 2 of the scoop 1 is wound on the drum of the winch 3, and the cable 8 from the winch 7 is stored on the block to 4. Disconnect the cable 8 from the cable 2 and lay

it is on the drum of the winch 7 (figure 2), while the cable 8 is stocked through the block 4. The winch 4 or its removable portable drum with a cable 8 is installed inside the laid pipe 6, near its rear end. Set on the guide 15 next

pipe 16 and join it, After that, in the manner described above, the ends of the cables 2 and 8 are connected, the winch (or drum) 7 is taken out of the pipe into the pit, the winch 7 is turned on (the direction of rotation is shown in Fig. 3) and the cable 2 of the scoop 1 is stored through the unit 4. Due to the fact that the flexible element 10 passes through the hole 13 in the jaws of the clamp 12, with the stock of the cable 2 of the scoop 1 through the block 4, the clamp cheeks are closer to the center of the block 4 than the end of the cable of the scoop and under the action of the tension of the cable 8, the end of the cable 2 of the scoop 1 is pressed to the tray of the block 4. The cable 8 is disconnected and the scoop 1 is attached to the end of cable 2

soil handling and transportation from the scoop 1.

The proposed device allows to reduce the cost of manual labor and time for the operation of transferring the scoop cable, which is repeatedly performed during trenchless laying of pipelines, depending on the length of the penetration, and generally improves the productivity of the installation.

The cable can be rearranged using the device described above not only in the horizontal direction, but also in any other, on various types of material handling equipment.
