Description

Technical Field

[0001] This application belongs to the field of mechanical equipment technology, specifically relating to an automatic cable dragging device for a tunnel boring machine. Background Technology

[0002] The automatic cable dragging device for roadheaders is a piece of equipment used in roadheader operations. It is mainly used to automatically drag and manage the power supply cables and other related cables of the roadheader. Its working principle is that the drive system drives the cable reel or cable traction mechanism to automatically reel in and out the cable according to the forward or backward movement of the roadheader. This ensures that the cable always maintains appropriate tension and length, avoiding situations such as the cable dragging on the ground, tangling, or excessive stretching. This ensures the normal operation of the roadheader, improves work efficiency, reduces the risk of manual intervention and cable damage, and enhances the safety and reliability of the operation.

[0003] If the dragging force provided by the dragging device is too large, it may cause excessive stretching of the cable, damaging the internal structure of the cable, affecting its electrical performance, and may even cause the cable to break, affecting the normal power supply and operation of the roadheader. If the dragging force is insufficient, the cable may become loose and accumulate around the roadheader or drag on the ground. It is not only easy to be crushed and damaged by the tracks or other parts of the roadheader, but may also affect the passage and operation safety of the construction site. Therefore, we have proposed an automatic cable dragging device for roadheaders. Utility Model Content

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See also Figure 1-5 As shown, an embodiment of this application provides an automatic cable dragging device for a roadheader, comprising: Base 1; The cable feeding roller 2 is disposed on the first end of the base 1 and is used to collect the cable. Adjustment component 3 is disposed on the base 1 and located on one side of the wire feeding roller 2. The adjustment component 3 is used to adjust the tension of the cable between the wire feeding roller 2 and the tunneling machine.

[0023] In this technical solution, the automatic cable dragging device for a roadheader provided in this application is used in roadheader operation scenarios, including a base 1, a cable release roller 2, and an adjustment component 3. The base 1 is used to install and fix the cable release roller 2 and the adjustment component 3, and the cable release roller 2 is used to store the cable. During the operation of the roadheader, as the roadheader moves forward or backward, the cable release roller 2 can release or retrieve the cable synchronously. When the roadheader advances forward, the cable release roller 2 gradually releases the cable to meet the cable length requirements during the roadheader's movement; when the roadheader moves backward for adjustment, the cable release roller 2 retrieves the excess cable to prevent the cable from scattering randomly and effectively reduce wear caused by dragging and scattering. The adjustment component 3 is set on the base 1 and located on one side of the cable release roller 2. It is used to adjust the tension of the cable between the cable release roller 2 and the roadheader, effectively extending the cable's service life and reducing the frequency of cable replacement.

[0024] According to some embodiments of this application, the adjustment component 3 includes: A support frame assembly 31 is disposed on the base 1, and a slide rail is provided on the support frame assembly 31; An adjustment frame 32 is disposed on the support frame assembly 31 and moves along the slide rail. The adjustment frame 32 has an inlet hole for fixing the cable. The first driving member 33 has one end movably connected to the base 1 and the output end of the first driving member 33 connected to the adjustment frame 32. The first driving member 33 is used to drive the adjustment frame 32 to slide along the slide rail to adjust the height of the adjustment frame 32 relative to the base 1.

[0025] In this technical solution, the adjustment component 3 includes a support frame assembly 31, an adjustment frame 32, and a first driving component 33. The support frame assembly 31 is mounted on the base 1 and has a slide rail for guiding the movement of the adjustment frame 32, allowing the adjustment frame 32 to slide along the slide rail and reducing abnormal situations such as offset or jamming during adjustment. The adjustment frame 32 has an inlet hole for fixing the cable. After the cable passes through the inlet hole, it is relatively fixed to the adjustment frame 32. The inlet hole can limit the cable and prevent the cable from falling off the adjustment frame 32 during adjustment. When the adjustment frame 32 slides along the slide rail, it will drive the cable to move synchronously. By changing the height of the adjustment frame 32 relative to the base 1, the tension of the cable can be adjusted, thus achieving the adjustment of the cable tension. One end of the first driving component 33 is movably connected to the base 1, and the output end is movably connected to the adjustment frame 32. It is used to provide power for the movement of the adjustment frame 32, and drive the adjustment frame 32 to slide along the slide rail to adjust the height of the adjustment frame 32 relative to the base 1. When the staff finds that the cable is loose, the staff can control the first driving component 33 to drive the adjustment frame 32 to move, raise the height of the adjustment frame 32, tighten the cable, and prevent the cable from piling up, dragging on the ground and being crushed and damaged.

[0026] It is understandable that the first driving component 33 is an electric push rod. One end of the first driving component 33 is rotatably connected to the base 1, and its output end is rotatably connected to the adjustment frame 32. Therefore, the first driving component 33 can output to drive the adjustment frame 32 to move along the slide rail.

[0027] According to some embodiments of this application, the support frame assembly 31 includes a support plate 311, a first limiting plate 312, and a second limiting plate 313. The support plate 311 is symmetrically arranged on the base 1. The slide rail extends obliquely upward from one end of the support plate 311 near the wire feeding roller 2 to the end away from the wire feeding roller 2. The first limiting plate 312 is disposed on the support plate 311 and located on the slide rail near the wire feeding roller 2. The second limiting plate 313 is disposed on the support plate 311 and located on the slide rail away from the wire feeding roller 2.

[0028] In this technical solution, the support frame assembly 31 includes a support plate 311, a first limiting plate 312, and a second limiting plate 313. Two support plates 311 are symmetrically mounted on the base 1 to provide double-sided support for the adjusting frame 32, improving the stability of the adjusting frame 32 as it moves along the slide rail on the support plate 311. The slide rail of the support plate 311 extends upwards at an angle from the end of the support plate 311 closest to the wire feeding roller 2 to the end furthest from the wire feeding roller 2. This means that as the adjusting frame 32 moves away from the wire feeding roller 2 along the slide rail, its height relative to the base 1 gradually increases, allowing for simultaneous cable tightening and resolving cable slack. Conversely, as the adjusting frame 32 moves closer to the wire feeding roller 2, its height gradually decreases, releasing cable tension and preventing excessive cable stretching. By mounting the first limiting plate 312 and the second limiting plate 313 on the support plate 311 at both ends of the slide rail, the stroke of the adjusting frame 32 can be limited, preventing the adjusting frame 32 from slipping off the support frame.

[0029] According to some embodiments of this application, the first drive member 33 is an electric push rod.

[0030] According to some embodiments of this application, the adjustment frame 32 includes: Transmission plate 321, wherein a wire inlet hole is provided on the transmission plate 321; The slider 322 is disposed on the transmission plate 321 and is slidably connected to the slide rail.

[0031] In this technical solution, the adjustment frame 32 includes a transmission plate 321 and a slider 322. The slider 322 is symmetrically installed at the bottom of the transmission plate 321. The transmission plate 321 can slide on the slide rail on the top of the support plate 311 through the slider 322. The cable inlet is opened on the transmission plate 321. When in use, the cable passes through the cable inlet. The cable inlet is used to constrain the cable. Therefore, when the transmission plate 321 slides on the slide rail through the slider 322, the tightness of the cable can be adjusted.

[0032] According to some embodiments of this application, a transmission assembly 4 is provided on the base 1 and located on both sides of the adjustment assembly 3, the transmission assembly 4 comprising: A limiting frame 41 is disposed on the base 1; The base 1 has a limiting hole, and the fixing plate 42 is disposed in the limiting hole. Limiting balls 43 are spaced apart in the fixing plate 42. Sliding plate 44, the sliding plate 44 being slidably disposed within the limiting frame 41; A connecting plate 45 is provided, the first end of which is connected to the side wall of the sliding plate 44, and the second end of the connecting plate 45 is provided with a limiting groove, which is movably connected to the limiting ball 43.

[0033] In this technical solution, the transmission assembly 4 includes a limiting frame 41, a fixing plate 42, limiting balls 43, a sliding plate 44, and a connecting plate 45. The limiting frame 41 is a frame structure with a sliding chamber inside for the sliding plate 44 to move. The limiting frame 41 is used to limit the sliding trajectory of the sliding plate 44. The fixing plate 42 is installed in a limiting hole on the base 1, and the limiting balls 43 are spaced apart on the fixing plate 42. When the sliding plate 44 moves within the limiting frame 41, the limiting balls 43 can limit and fix the limiting groove of the connecting plate 45, thereby limiting the movement of the sliding plate 44 so that it can slide to the target position according to the usage requirements.

[0034] The wire feeding roller 2 includes: Connecting piece 21, which is rotatably mounted on the top of the sliding plate 44; A connecting frame 22 is rotatably mounted on the connecting piece 21, and a rotating shaft 23 is rotatably mounted between the connecting frames 22; Roller body 24, the roller body 24 being disposed on the rotating shaft 23; The second driving component 25 is disposed on one side of the connecting frame 22. The output end of the second driving component 25 is connected to the rotating shaft 23 and is used to drive the rotating shaft 23 to rotate.

[0035] The pay-off roller 2 also includes: The limiting frame 26 has its first end connected to the connecting frame 22 and its second end in contact with the base 1.

[0036] In this technical solution, the wire feeding roller 2 includes a connecting piece 21, a connecting frame 22, a rotating shaft 23, a roller body 24, a second driving component 25, and a limiting frame 26. The connecting piece 21 is rotatably mounted on the top of the sliding plate 44, allowing the connecting frame 22 to be installed. The rotating shaft 23 is rotatably mounted between the connecting frames 22. The roller body 24 is fixedly mounted on the rotating shaft 23. The cable is wound around the outer surface of the roller body 24 and is wound and unwound as the rotating shaft 23 rotates. The output end of the second driving component 25 is connected to the rotating shaft 23 to drive the rotating shaft 23 to rotate. The second driving component 25 provides power for the winding and unwinding of the wire feeding roller 2 and can adaptively adjust the output speed according to the tunneling speed of the roadheader to ensure that the cable winding and unwinding speed matches the moving speed of the roadheader, avoiding cable tension or slack accumulation due to untimely winding and unwinding. The first end of the limiting frame 26 is connected to the connecting frame 22, and the second end contacts the base 1, used to limit and fix the connecting frame 22. During use, when the operator slides the sliding plate 44 to move it within the limiting frame 41, the roller 24 cannot move with the sliding plate 44 when the limiting frame 26 limits and fixes the connecting frame 22 and the roller 24. However, the connecting piece 21 is rotatably connected to the top of the sliding plate 44. Therefore, as the sliding plate 44 moves continuously, the angle of the connecting piece 21 relative to the sliding plate 44 changes, which can change the height of the connecting frame 22 and the roller 24 relative to the base 1, thereby adjusting the height of the roller 24.

[0037] According to some embodiments of this application, a rotating shaft 27 is provided between the top of the sliding plate 44 and the connecting piece 21.

[0038] According to some embodiments of this application, the base 1 is provided with support legs 5 at its four corners.

[0039] In this technical solution, the support legs 5 are installed at the four corners of the base 1 to support and fix the base 1.
