[0053] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0054] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0055] EMBODIMENT

[0056] Please refer to Figure 1 , Figure 2 and Figure 3 The present embodiment provides a drum lifting device. The drum lifting device can be applied to a front-shovel excavator.

[0057] The drum lifting device provided by the embodiment comprises a base 100, a driving device 200, a side support 300 and a drum body 400. The base 100 is arranged on a rotary platform, and a first mounting seat 110 and a second mounting seat 120 are arranged on the base 100 in a spaced manner. The distance between the first mounting seat 110 and the second mounting seat 120 is used to accommodate the drum body 400.

[0058] The driving device 200 is arranged on the first mounting seat 110, and a threaded connection seat 220 is arranged on the side of the driving device 200 facing the second mounting seat 120.

[0059] Specifically, the driving device 200 comprises a speed reduction mechanism 210 and a motor or an engine in transmission connection with the speed reduction mechanism 210. The speed reduction mechanism 210 is mounted on the second mounting seat 120.

[0060] The side support 300 is arranged on the second mounting seat 120, and the side support 300 is provided with a first pin hole 310 penetrating in the thickness direction of the side support 300.

[0061] The drum body 400 is provided with a side plate 410 and a drum shaft 420 at both ends thereof. The side plate 410 is provided with a lifting through hole 411 and an assembly through hole 412, and the assembly through hole 412 is aligned with a threaded hole on the threaded connection seat 220. The drum shaft 420 at both ends of the drum body 400 is connected with the speed reduction mechanism 210 of the driving device 200 and the side support 300, respectively. In the embodiment, the drum shaft 420 and the speed reduction mechanism 210 can be connected by means of spline connection.

[0062] Further, the end of the drum body 400 close to the side support 300 is also provided with a second pin hole. When the drum body 400 is lifted, a limiting pin 500 is arranged to pass through the first pin hole 310 and the second pin hole, so as to constrain the bottom of the side support 300 upward.

[0063] In the embodiment, a plurality of lifting through holes 411 are arranged on the side plate 410 around the axis of the drum body 400, so as to select different lifting holes according to the length of the lifting rope (steel wire rope or lifting belt) on the crane. The plurality of lifting through holes 411 on each side plate 410 are arranged symmetrically about one of the radial planes passing through the axis of the drum body 400. In this way, two symmetric lifting holes can be selected on each side plate 410 to install the lifting rope each time the drum body 400 is lifted, and the lifting ropes on both sides are gathered on the lifting hook of the crane, so as to ensure the safety and stability of lifting.

[0064] Further, the deceleration mechanism 210 of the driving device 200 is provided with at least two threaded connection seats 220, and the at least two threaded connection seats 220 are symmetrically arranged about the output end of the driving device 200. The side wall plate 410 is provided with at least one assembly through hole 412 corresponding to each threaded connection seat 220. In order to facilitate subsequent assembly, at least two push modules 600 are used to simultaneously apply a transverse force, so that the winding drum body 400 can be stably pushed forward, and the safety of assembly is improved.

[0065] The bottom of the side support 300 is provided with an ear 320, so as to facilitate hoisting of the side support 300 during assembly.

[0066] As shown in the drawings, further, the embodiment also provides a push module 600 for assembling the winding drum lifting device, which is applied to the winding drum lifting device and is used during assembly of the winding drum lifting device. Figure 3

[0067] In the use state, the push end of the hand cylinder 620 is arranged to face one end of the long screw rod 610, and the stop nut 630 is screwed on the other end of the long screw rod 610 to abut against the hand cylinder 620.

[0068] It can be understood that, during assembly of the winding drum lifting device, one end of the long screw rod 610 is used to pass through the assembly through hole 412 and be connected with the threaded connection seat 220, the other end of the long screw rod 610 is exposed on the side of the side wall plate 410 away from the threaded connection seat 220, the push end of the hand cylinder 620 abuts against the side of the side wall plate 410 away from the threaded connection seat 220, and is used to apply a transverse force along the length direction of the long screw rod 610, and the stop nut 630 abuts against the hand cylinder 620. In this way, after the push module 600 is installed between the winding drum body 400 and the threaded connection seat 220, due to the existence of the stop nut 630 and the freedom of transverse movement of the winding drum body 400 (along the length direction of the long screw rod 610), when the push end of the hand cylinder 620 is extended, the winding drum body 400 can be pushed to move in the direction of approaching the deceleration mechanism 210. Since the stroke of the hand cylinder 620 is limited, a single push cannot push the winding drum body 400 to the assembly position, so after one push is completed, the hand cylinder 620 can be pushed forward by screwing the stop nut 630, so that the push end of the hand cylinder 620 continues to abut against the side wall plate 410, and the hand cylinder 620 is started to repeat the above operation until the winding drum shaft 420 of the winding drum body 400 is assembled to the position of the deceleration mechanism 210, and then the entire push module 600 is removed.

[0069] ​Further, the embodiment is provided with a first plane part penetrating along the length direction of the long screw rod 610 on the outer circumferential surface of the long screw rod 610, and a second plane part penetrating along the axial direction of the assembly through hole 412 on the inner wall of the assembly through hole 412. In this way, when the winding drum lifting equipment is assembled, the first plane part is arranged towards the second plane part. Thus, the winding drum body 400 will not be affected by the thread on the long screw rod 610 when moving, the relative sliding friction between the two plane parts is smaller, and at the same time, the thread on the surface of the long screw rod 610 will not be damaged, prolonging the service life of the long screw rod 610 and the whole jacking module 600.

[0070] Please refer to Figure 4 The embodiment also provides a jacking module 700 for assembling the winding drum lifting equipment.

[0071] The jacking module 700 provided by the embodiment comprises a base 710, a top base 720 and an adjusting part 730. The base 710 is used for providing support; the top base 720 is arranged in position with the base 710, and an arc-shaped supporting surface 7210 for adapting to the shape of the outer circumferential surface of the winding drum body 400 is arranged on the end of the top base 720 away from the base 710, so as to reduce the damage to the outer circumferential surface of the winding drum body 400 when supporting.

[0072] The adjusting part 730 is arranged between the base 710 and the top base 720 and is adjustably connected with the base 710 and the top base 720, and is used for adjusting the distance between the base 710 and the top base 720.

[0073] In this way, when the winding drum lifting equipment is assembled, the whole jacking module 700 is placed below the winding drum body 400, the base 710 abuts against the base 100, and the arc-shaped supporting surface 7210 of the top base 720 supports the outer circumferential surface of the winding drum body 400 in the vertical direction. When the supporting distance is not enough, the distance between the base 710 and the top base 720 can be adjusted through the adjusting part 730, so as to ensure that the arc-shaped supporting surface 7210 of the top base 720 abuts against the outer circumferential surface of the winding drum body 400.

[0074] It should be noted that the number of jacking modules 700 can be multiple, and multiple jacking modules 700 jointly support the winding drum body 400 to improve safety.

[0075] Specifically, the adjusting part 730 is a screw shaft, and the screw shaft is sequentially provided with a first screw segment 731, a screwing segment 732 and a second screw segment 733 along the axial direction. The screw threads of the first screw segment 731 and the second screw segment 733 are in different directions, and the radial cross section of the screwing segment 732 is hexagonal or polygonal, so as to facilitate the screwing of a tool.

[0076] The base 710 is provided with an internal threaded hole threadedly matched with the first screw rod segment 731, and the top base 720 is provided with an internal threaded hole threadedly matched with the second screw rod segment 733. In this way, the distance between the top base 720 and the base 710 can be adjusted by rotating the screwing segment 732 clockwise or counterclockwise.

[0077] Further, the top base 720 comprises a first support plate 721, a first support cylinder 722 and a first reinforcing rib plate 723. One side of the first support plate 721 is provided with an arc-shaped support surface 7210, and the other side of the first support plate 721 is connected with the first support cylinder 722. The first support cylinder 722 is internally provided with an internal threaded hole threadedly matched with the second screw rod segment 733, and the outer circumferential surface of the first support cylinder 722 is provided with a plurality of first reinforcing rib plates 723, which are respectively welded and connected with the first support cylinder 722 and the first support plate 721. The arrangement of the first reinforcing rib plates 723 can improve the structural strength of the entire top base 720.

[0078] The base 710 comprises a second support plate 711, a second support cylinder 712 and a second reinforcing rib plate 713. One side of the second support plate 711 is provided with a support flat surface, and the other side of the second support plate 711 is connected with the second support cylinder 712. The second support cylinder 712 is internally provided with an internal threaded hole threadedly matched with the first screw rod segment 731, and the outer circumferential surface of the second support cylinder 712 is provided with a plurality of second reinforcing rib plates 713, which are respectively welded and connected with the second support cylinder 712 and the second support plate 711. The arrangement of the second reinforcing rib plates 713 can improve the structural strength of the entire base 710.
