Description

Technical Field

[0001] The utility model relates to the technical field of cable reel supports, in particular to a support device for a cable reel of a crawler single-arm tunneling jumbo. Background Art

[0002] The cable reel of a crawler single-arm tunneling jumbo is used for winding explosion-proof cables. The existing cable reel is supported by a single support base, and its support capacity is relatively strong. If the length of the wound cable is too long, its load-bearing capacity is relatively large, so it cannot wind long cables. At the same time, its support height cannot be adjusted, and its height from the base is a fixed value, so it cannot wind long cables and cannot meet the use requirements. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a support device for a cable reel of a crawler single-arm tunneling jumbo, which has good support stability and adjustable support height, so that the cable reel can wind longer cables and can effectively solve the problems in the background art.

[0022] The driving mechanism 3 includes a rotating shaft 31, a driven gear 32, a driving gear 33 and a rotating shaft 37. The driven gear 32 is rotatably mounted on the top of the vehicle-mounted connecting seat 1 through the rotating shaft 31, and the driving gear 33 is rotatably mounted on the middle of the vehicle-mounted connecting seat 1 through the rotating shaft 37. The driving gear 33 is meshed with the driven gear 32. The driving mechanism 3 also includes a servo motor 34, a chain 35, a driven sprocket 36 and a driving sprocket 38. The servo motor 34 is mounted at the bottom of the vehicle-mounted connecting seat 1, and the driving sprocket 38 is fixed to the servo motor 34. On the output shaft, the driven sprocket 36 is sleeved and fixed on the rotating shaft 37, and the driving sprocket 38 is connected to the driven sprocket 36 through the chain 35. The servo motor 34 is electrically connected to the on-board controller of the excavation vehicle. The output shaft of the servo motor 34 drives the driving sprocket 38 to rotate. The driving sprocket 38 is transmitted to the driven sprocket 36 through the chain 35. The driven sprocket 36 drives the driving gear 33 to rotate through the rotating shaft 37. The driving gear 33 is meshed with the driven gear 32 for transmission. Multiple lifting mechanisms 4 can be driven by this driving structure.

[0023] The lifting mechanism 4 includes a screw rod 43 and a threaded cylinder 44. The screw rod 43 is fixed at the end of the rotating shaft 31. The threaded cylinder 44 is threadedly connected to the screw rod 43. The lifting mechanism 4 also includes a telescopic rod 41 and a lifting seat 42.

The driven gear 32 drives the screw rod 43 to rotate through the rotating shaft 31. The screw rod 43 and the threaded cylinder 44 are threadedly transmitted. The threaded cylinder 44 drives the lifting seat 42 to perform a lifting movement, thereby adjusting the support height of the cable reel support seat 2. The lifting seat 42 drives the telescopic rod 41 to perform a telescopic movement during the lifting process. By adjusting the support height of the cable reel support seat 2, the space at the bottom of the cable reel is made large enough so that it can be wound with longer cables, which is convenient for meeting usage requirements.

[0024] The working principle of a cable drum support device for a crawler single-arm tunneling trolley provided by the utility model is as follows: the output shaft of a servo motor 34 drives a driving sprocket 38 to rotate, and the driving sprocket 38 is transmitted through a chain 35 and a driven sprocket 36, and the driven sprocket 36 drives a driving gear 33 to rotate through a rotating shaft 37, and the driving gear 33 is meshed with a driven gear 32 for transmission, and the driven gear 32 drives a screw rod 43 to rotate through a rotating shaft 31, and the screw rod 43 is threadedly transmitted with a threaded cylinder 44, and the threaded cylinder 44 drives a lifting seat 42 to perform a lifting movement, thereby adjusting the support height of a cable drum support seat 2, and the lifting seat 42 drives the telescopic rod 41 to perform a telescopic movement during the lifting process, and by adjusting the support height of the cable drum support seat 2, the space at the bottom of the cable drum is made large enough so that it can wind longer cables, and there are two groups of cable drum support seats 2, thereby ensuring the stability of the cable drum support.
