DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide a rope-driven sluice wire rope automatic climbing device, which utilizes a traction rope to assist climbing and ensure climbing efficiency and stability.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 9The present embodiment provides a rope-driven sluice wire rope automatic climbing device (hereinafter referred to as the automatic climbing device), including a climbing device body and a rope driving mechanism. The climbing device body includes a device frame 4. The rope driving mechanism includes a hook 2, a traction rope 3 and a rope driving transmission mechanism 5. The rope driving transmission mechanism 5 includes a winding wheel 57 and a driving motor 52. The driving motor 52 is connected to the device frame 4. The driving motor 52 is connected to the winding wheel 57. One end of the traction rope 3 is connected to the winding wheel 57. The other end of the traction rope 3 is connected to the hook 2. The hook 2 is used to be hung in a fixed position.

[0034] Exemplarily, the driving motor 52 is a DC reduction motor to improve the control accuracy of the traction rope 3. The diameter of the traction rope 3 is a steel wire rope 1 of 1mm to 3mm, and the user can choose a traction rope 3 of other diameters according to different actual loads. The device frame 4 is built of industrial aluminum profiles.

[0035] The working principle of the automatic climbing device is as follows:

[0036] The climbing device body is a robot that has the function of climbing along the steel wire rope 1, but it usually slips when climbing along the oily steel wire rope 1. In this embodiment, a rope drive mechanism is added, and the rope drive mechanism is used to unwind the traction rope 3 to realize the downward movement of the climbing device body, and the rope drive mechanism is used to rewind the traction rope 3 to realize the upward movement of the climbing device body, thereby ensuring the position control of the climbing device body, so that it can move to the specified position of the steel wire rope 1 within a limited time, and avoid being damaged due to slipping.

[0037] The rope drive transmission mechanism 5 can be of various types, as long as it can realize the unwinding and rewinding of the traction rope 3. As a possible example, in this embodiment, the rope drive transmission mechanism 5 also includes a pinion, a coupling 56, a large gear 53 and a support frame 50, the pinion is connected to the output shaft of the drive motor 52 through the coupling 56, the pinion is meshed with the large gear 53, the large gear 53 is coaxially fixed with the winding wheel 57, the pinion and the large gear 53 are both rotatably mounted on the support frame 50, and the support frame 50 is connected to the device frame 4.

[0038] The driving motor 52 drives the small gear to rotate through the coupling 56, and the small gear drives the large gear 53 to rotate through meshing transmission, and the large gear 53 drives the winding wheel 57 to rotate, thereby realizing the winding and unwinding of the traction rope 3 on the winding wheel 57.

[0039] As a possible example, in this embodiment, the rope-driven transmission mechanism 5 further includes a V-shaped fixed pulley 55 , which is rotatably mounted on the support frame 50 , and the traction rope 3 passes around the V-shaped fixed pulley 55 .

[0040] By providing the V-shaped fixed pulley 55 , the path of the traction rope 3 can be controlled to avoid friction between the traction rope 3 and the climbing device body, thereby reducing transmission resistance and wear of the traction rope 3 .

[0041] As a possible example, in this embodiment, the axle 59 of the pinion gear and the axle 59 of the large gear 53 (the axle 59 has a center hole) are both sleeved on the corresponding center bolt 58, and the center bolt 58 is fixed on the support frame 50. The support frame 50 is a U-shaped structure, and the center bolt 58 passes through the two vertical plates of the U-shaped structure respectively and is locked by the corresponding locking nut 54. By directly sleeved the axles 59 of the pinion gear and the large gear 53 on the corresponding center bolt 58, the installation process of the bearing is omitted, thereby reducing the manufacturing cost of the device, simplifying the assembly process, and facilitating maintenance.

[0042] As a possible example, in this embodiment, the rope-driven transmission mechanism 5 also includes an L-shaped bracket 51, the drive motor 52 is fixedly connected to the L-shaped bracket 51, and the L-shaped bracket 51 is fixedly connected to the device frame 4 to achieve an indirect connection between the drive motor 52 and the device frame 4.

[0043] As a possible example, in this embodiment, the automatic climbing device further includes a traction rope guide block 11, the traction rope 3 passes through the traction rope guide hole on the traction rope guide block 11, and the traction rope guide block 11 is connected to the device frame 4. The function of the traction rope guide block 11 is similar to that of the V-shaped fixed pulley 55, both of which limit the position of the traction rope 3. The traction rope guide block 11 is preferably arranged near the geometric center of the upper end of the device frame 4, so as to keep the device frame 4 in a nearly vertical posture as much as possible.

[0044] As a possible example, in this embodiment, the automatic climbing device also includes an anti-deviation mechanism 10, and the anti-deviation mechanism 10 includes four L-shaped anti-deviation brackets 100. The device frame 4 is a rectangular structure with an internal space, including a left frame 20 and a right frame 21, and the left frame 20 and the right frame 21 both include beams 203 and columns 202, and the L-shaped anti-deviation brackets 100 connect the beams 203. Two L-shaped anti-deviation brackets 100 and the two beams 203 of the upper layer form an upper anti-deviation hole, and the other two L-shaped anti-deviation brackets 100 and the two beams 203 of the lower layer form a lower anti-deviation hole, and the upper anti-deviation hole and the lower anti-deviation hole are aligned vertically, and the upper anti-deviation hole and the lower anti-deviation hole are for the steel wire rope 1 to pass through.

[0045] Exemplarily, one of the two beams 203 that enclose the upper anti-bias hole is located on the left frame 20, and the other is located on the right frame 21. One of the two beams that enclose the lower anti-bias hole is located on the left frame 20, and the other is located on the right frame 21. In this way, the upper anti-bias hole and the lower anti-bias hole are both located between the left frame 20 and the right frame 21, that is, located at the center of the device frame 4, thereby ensuring that the steel wire rope 1 passes through the center position of the device frame 4, so that the device frame 4 can maintain a vertical posture as much as possible.

[0046] As a possible example, in this embodiment, the device frame 4 further includes a hinge 204 and a locking assembly 201, the front end of the left frame 20 and the front end of the right frame 21 are hingedly connected through the hinge 204, and the rear end of the left frame 20 and the rear end of the right frame 21 are detachably locked and connected through the locking assembly 201. The locking assembly 201 includes a pull ring and a hook, and the pull ring is used to be hung with the hook.

[0047] The hinge 204 is provided to realize the relative rotation of the left frame 20 and the right frame 21. The pull ring is hung on the hook to lock the position of the left frame 20 and the right frame 21, so that the device frame 4 is kept closed. When in use, the device frame 4 is first opened, the steel wire rope 1 passes through the device frame 4 in the up and down direction, and then the device frame 4 is closed.

[0048] As a possible example, in this embodiment, the climbing device body also includes a guiding mechanism, which includes a fixed frame 6, a movable frame 7, a U-shaped wheel 600, a clamping assembly and a spring 705. The fixed frame 6 is fixedly connected to the left frame 20, and the movable frame 7 is slidably connected to the right frame 21 along the left and right directions. The U-shaped wheel 600 is rotatably installed on both the fixed frame 6 and the movable frame 7 to clamp the wire rope 1 through the U-shaped wheels 600 on the left and right sides of the wire rope 1 to prevent the wire rope 1 from detaching. The clamping assembly is installed on the right frame 21, and the distance between it and the movable frame 7 is adjustable. The spring 705 is arranged between the movable frame 7 and the clamping assembly to change the pre-compression amount of the spring 705 by adjusting the position of the clamping assembly.

[0049] When in use, by adjusting the position of the clamping assembly on the right frame 21 and changing the distance between the clamping assembly and the movable frame 7, the pre-compression amount of the spring 705 is adjusted, thereby realizing the adjustment of the clamping force of the U-shaped wheel 600 on the fixed frame 6 and the movable frame 7 on the wire rope 1.

[0050] As a possible example, in this embodiment, the clamping assembly includes a position adjustment screw 708, a handle 709 and a pressing plate 710. The position adjustment screw 708 is threadedly connected to the right frame 21, the handle 709 is connected to the end of the position adjustment screw 708 away from the movable frame 7, the end of the position adjustment screw 708 close to the movable frame 7 is in contact with the pressing plate 710, and the spring 705 is arranged between the movable frame 7 and the pressing plate 710. A clamping block 707 is arranged at the end of the position adjustment screw 708 close to the movable frame 7, and the cross-sectional area of ​​the clamping block 707 is larger than that of the position adjustment screw 708, thereby increasing the contact area with the pressing plate 710, so that the pressing plate 710 is translated with the axial movement of the position adjustment screw 708, and the pressing plate 710 is prevented from rotating.

[0051] When in use, by turning the handle 709, the adjusting screw is driven to rotate, thereby changing the axial position of the adjusting screw, and then changing the position of the pressure plate 710 and the pre-compression amount of the spring 705, thereby adjusting the clamping force of the U-shaped wheel 600 on the fixed frame 6 and the movable frame 7 on the wire rope 1.

[0052] As a possible example, in this embodiment, the fixed frame 6 includes a left upper bracket 601, a left lower bracket 604, a left vertical plate 603 and a left support shaft 602. The left upper bracket 601 is fixed to the upper part of the left frame 20, and the left lower bracket 604 is fixed to the lower part of the left frame 20. Three left support shafts 602 are installed on the left vertical plate 603 from top to bottom, and a U-shaped wheel 600 is rotatably installed on each left support shaft 602. The upper left support shaft 602 passes through the left upper bracket 601, and the lower left support shaft 602 passes through the left lower bracket 604.

[0053] As a possible example, in this embodiment, the movable frame 7 includes a right upper bracket 704, a right lower bracket 702, a right vertical plate 703, a right support shaft 701 and a guide shaft 706. Three right support shafts 701 are installed on the right vertical plate 703 from top to bottom, and a U-shaped wheel 600 is rotatably installed on each right support shaft 701. The upper right support shaft 701 passes through the right upper bracket 704, and the lower right support shaft 701 passes through the right lower bracket 702. The right upper bracket 704 and the right lower bracket 702 are fixedly connected to the guide shaft 706, which extends in the left-right direction and is slidably connected to the right frame 21, and is used to guide the sliding of the movable frame 7 in the left-right direction. A spring 705 is sleeved on the outer side of each guide shaft 706. The middle part of the right vertical plate 703 is rotatably connected to the adjusting screw, so that the right upper bracket 704 and the right lower bracket 702 move synchronously. The threaded hole matching the adjusting screw and the guide through hole matching the guide shaft 706 are both arranged on the column 202 of the right frame 21. The ends of the left support shaft 602 and the right support shaft 701 are both locked by the fastening nut 605.

[0054] As a possible example, in this embodiment, the climbing device body further includes a controller 9 and a counterweight 8. The controller 9 is electrically connected to the drive motor 52 and is used to control the direction and speed of the drive motor 52. The counterweight 8 is fixed to the right frame 21 and is close in weight to the rope drive transmission mechanism 5, so that the center of gravity of the automatic climbing device is located at its center, so that the device frame 4 can maintain a vertical posture as much as possible.
