Description

Technical Field

[0001] This application belongs to the field of shield construction devices. Specifically, it particularly relates to a flexible cable pay-off device for a shield machine. Background Art

[0002] When using shield cables, it is often necessary to pay off the flexible cable from the cable reel for use. To solve the natural drawbacks of traditional manual pay-off, the prior art provides a flexible cable pay-off device for a shield. Referring to the content disclosed in the patent document with the Chinese patent publication number CN214879109U, it includes a wire winding mechanism. A wire body is provided on the wire winding mechanism. Two mounting frames are provided outside the wire winding mechanism. A connecting roller is provided between the two mounting frames. The connecting roller is provided with a groove. A fixing component is provided in the groove. The fixing component includes a pressing plate, two positioning columns, and two tension springs. When paying off the wire, one end of the wire body can be inserted into the groove of the connecting roller, and the pressing plate is pulled to make the wire body located in the pressing hole. The pressing plate can press the wire body under the action of the tension spring, so that one end of the wire body can be quickly fixed. Then, the mounting frame is moved under the action of the casters, so that the wire body on the wire winding mechanism can be paid off to assist in paying off the wire, avoiding directly operating the wire body, reducing the labor intensity, and the mounting frame can limit the position of the paid-off wire body, facilitating the operation of the cable.

[0003] In the above structure, there are two problems that need to be further solved.

[0004] First, the wire winding mechanism disclosed in the patent document CN214879109U is composed of a wire winding roller and a frame body to facilitate paying off or winding the cable from the wire winding roller. However, in the actual wire pay-off process, the length of the cable is relatively long, and more wire winding rollers may be required. This wire pay-off and winding structure of the wire winding roller is not suitable for the situation of having more wire winding rollers.

[0005] Secondly, it needs to cooperate with the mounting frame. Although there is a fixing component for mounting the wire body on the mounting frame, limited by the left and right movement of the wire during winding on the wire winding roller (i.e., during the process of winding from one end of the wire winding roller to the other end), the winding and wire pay-off effects of the above structure are not ideal during use, and more manual labor is still required to manipulate the movement and movement path of the mounting frame to achieve adaptation to the wire pay-off direction of the cable. Summary of the Invention

[0006] The purpose of this application is to provide a flexible cable pay-off device for a shield machine, which can improve the cooperation degree between the cable reel and the pay-off device, improve the adaptability of the pay-off device to the cable reel, and facilitate guiding the direction of the cable during the wire pay-off process.

A corresponding shaft body connecting seat 35 is also arranged between the shaft bodies of the adjacent upper press wheels 19. The shaft body connecting seat 35 is located at the telescopic end of the corresponding bottom support adjuster 6. The bottom support adjuster 6 is located at the bottom end of the assembly fixing plate 25 and is fixedly connected to the assembly fixing plate 25 as a whole (in order to avoid the occlusion of overlapping components, it is not shown in the attached Figures 1 to 3 drawing).

[0031] A driving assembly 24 is fixedly connected to the top end of the assembly fixing plate 25. The driving assembly 24 is a driving motor with a speed reducer. The driving assembly 24 drives a driving shaft 22. The driving shaft 22 is connected to the assembly fixing plate 25 through a bearing seat 23.

The guide cylinder support rod 15 is connected to the guide cylinder vertical rod 8 as a whole through a fixing member after passing through the guide cylinder longitudinal hole 14.

[0033] Embodiment 2

[0034] As Figures 1 to 3 shown, for a flexible cable pay-off device of a shield machine, the bottom of the guide cylinder vertical rod 8 is connected with a U-shaped card seat 13. The U-shaped card seat 13 is clamped on the top ends of the adjacent side plates on the same side of the frame 9. The U-shaped card seat 13 is fixedly connected to the guide cylinder adjusting seat 11. The guide cylinder adjusting seat 11 is located between the adjacent side plates. The guide cylinder adjusting seat 11 is connected to the guide cylinder adjusting hole 12 on the side plate through an adjusting fixing member.

[0035] The frame 9 is fixedly connected to a traction seat 10 at one end away from the side plate inlet end 29, and an inlet inclined plate 28 is provided at the side plate inlet end 29. The structure and connection relationship of the remaining parts are the same as those described in any one of the above embodiments, and will not be repeated here to avoid cumbersome text.

[0036] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles played by the technical features in the present technical solution, so as to help technicians in this field to fully understand the technical solution and reproduce it.

[0037] The base 1 described in the present application may be provided with a walking structure so as to facilitate better movement through the traction seat 10 .

[0038] The side plate inlet end 29 with the inlet inclined plate 28 described in the present application can realize the rolling in of a wooden cable drum or a cable drum made of other materials, so that the circular edge of the cable drum can be supported by the bottom supporting wheel body 3 .

[0039] The bottom supporting wheel bodies 3 are located on both sides of the cable drum, and can support the cable drum and assist the rotation of the cable drum.

[0040] The upper pressure wheel 19 is arranged corresponding to the bottom supporting wheel body 3. The upper pressure wheel 19 follows the assembly fixing plate 25 and is lifted and lowered relative to the bottom supporting wheel body 3 under the action of the lifting cylinder 4. The upper pressure wheel 19 is driven by the driven wheel 18 arranged on the coaxial body. The driven wheel 18 is driven by the driving wheel 21 through the synchronous driving belt 20. The driving wheel 21 rotates following the driving shaft 22. The driving shaft 22 is driven by the driving assembly 24. The driving assembly 24 is a driving motor with a reduction mechanism or other mechanism that can drive the driving shaft 22 to rotate.

[0041] The assembly fixing plate 25 is lifted and lowered following the adjusting sleeve 17 at the corner position under the action of the lifting cylinder 4 . The adjusting sleeve 17 is a sleeve with a rectangular cross-section adapted to the cross-section of the lifting adjustment rod 7 .

[0042] The guiding cylinder 16 is located in the outlet direction of the frame 9 away from the inlet inclined plate 28. It includes a guiding inlet curled end 30 with a horn-shaped structure, a guiding straight cylinder section 31 with a straight cylinder structure, and a guiding outlet curled end 32 with a horn-shaped structure. The guiding inlet curled end 30 and the guiding outlet curled end 32 are arranged on both sides of the guiding straight cylinder section 31 and form an integral body with the guiding straight cylinder section 31. At the edge positions of the guiding inlet curled end 30 and the guiding outlet curled end 32, a smooth transition structural form is adopted to reduce the friction with the cable. At the same time, a number of ball bearings 33 are distributed on the inner walls of the guiding inlet curled end 30, the guiding straight cylinder section 31, and the guiding outlet curled end 32 in contact with the cable. The ball bearings 33 can ensure good passing performance when the cable contacts the above structures and reduce the friction area between the cable and the inner wall. At the same time, during actual use, the guiding cylinder 16 can also be adjusted in height relative to the frame 9. The height adjustment is mainly achieved by the guiding cylinder support rod 15 and the corresponding guiding cylinder longitudinal holes 14 and guiding cylinder vertical rods 8 on both sides.

[0043] The guiding cylinder vertical rod 8 can also be adjusted in distance on the horizontal plane, which is mainly achieved by the sliding of the guiding cylinder adjusting seat 11 between the adjacent side plates on both sides of the frame 9 along the guiding cylinder adjusting hole 12. The position of the guiding cylinder adjusting seat 11 and the guiding cylinder adjusting hole 12 is fixed through a fixing member.

[0044] Finally, although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
