DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0028] like Figure 1 and 2As shown, a single-rod lifting device for a large depth-to-diameter ratio manhole desilting robot provided according to the present invention includes: a lifting connecting rod, a connecting rod lifting mechanism, a cleaning device mounting mechanism, an electric hoist 7 and a working platform 3; the lifting connecting rod, the connecting rod lifting mechanism and the electric hoist 7 are all installed on the working platform 3; the lifting connecting rod is transmission-connected to the connecting rod lifting mechanism, and the lifting connecting rod is rotationally matched with the working platform 3 through the connecting rod lifting mechanism; the cleaning device mounting mechanism is installed on the lifting connecting rod, the cleaning device mounting mechanism is transmission-connected to the electric hoist 7, and the cleaning device mounting mechanism is slidingly matched with the lifting connecting rod through the electric hoist 7.

[0029] The present application provides a detachable, easy-to-transport, portable lifting device. The lifting link in the present application includes a horizontal state and a vertical state. The lifting link is assembled in a horizontal state, lifted to a vertical state by a link lifting mechanism, and fastened to the working platform 3. Driven by the electric hoist 7, the cleaning device mounting mechanism on the lifting link slides up and down along the lifting link, thereby driving the silt removal robot installed on the cleaning device mounting mechanism to perform cleaning actions. After the work is completed, the lifting link is laid down to a horizontal state by the link lifting mechanism for disassembly. The present application has a simple structure, can be quickly assembled and disassembled, is easy to transport, and greatly saves labor and transportation costs.

[0030] like Figure 3 As shown, the lifting link comprises multiple aluminum square tubes 1 connected end to end, with any two adjacent aluminum square tubes 1 being detachably connected. The adjacent ends of the two aluminum square tubes 1 are formed with a protrusion and a recessed hole, respectively. The protrusion and recessed holes are correspondingly provided with fixing holes 2. The protrusion and recessed holes are joined together and secured through the fixing holes 2. Typically, the top of the aluminum square tubes 1 protrudes to form a protrusion, while the tail is recessed to form a recessed hole. After the two aluminum square tubes 1 are joined end to end, they are screwed together at the fixing holes 2 to form a horizontal lifting link.

[0031] like Figure 4 As shown, the bottom of the lifting link is provided with an articulated sleeve 14, which is provided with a connecting rod connection hole 16 and a fixing base fixing hole 15. After the lifting link is assembled, the bottom of the lifting link is fixed to the articulated sleeve 14 through the connecting rod connection hole 16 and screws. The working platform 3 is mounted with an articulated fixing base 4, and the articulated sleeve 14 is hingedly connected to the articulated fixing base 4. After the lifting link is raised to a vertical position by the link lifting mechanism, the articulated fixing base 4 is fixed to the articulated fixing base 4 through the fixing base fixing hole 15 and screws and nuts, thereby ensuring the vertical stability of the lifting link.

[0032] like Figure 5As shown, a pull ring 17 is provided on the side of the articulated sleeve 14 near the connecting rod lifting mechanism. The connecting rod lifting mechanism includes an electric winch 5 and a reversing column 6. The pulling rope of the electric winch 5 passes through the reversing column 6 and is connected to the pull ring 17. A reversing column fixed pulley is installed on the top of the reversing column 6. After the rope of the electric winch 5 passes through the reversing column fixed pulley on the reversing column 6, it is fixed to the articulated sleeve 14, thereby pulling up or down the lifting link.

[0033] A fixed pulley 8 is located at the top of the lifting link. The steel cable of the electric hoist 7 passes over this fixed pulley 8 and connects to the cleaning device mounting mechanism. The rope of the electric hoist 7 passes upward through the fixed pulley 8 at the top of the lifting link and is secured to the cleaning device mounting mechanism or to the cleaning device of the dredging robot. By retracting and releasing the rope of the electric hoist 7, the dredging robot can be pulled up or down, completing the cleaning task.

[0034] like Figure 6 As shown, the cleaning device mounting mechanism includes a sliding square tube 9, which is sleeved onto the lifting connecting rod. Ball bearings 10 are installed inside the sliding square tube 9, through which the sliding square tube 9 slides with the lifting connecting rod. A fixed plate 13 is provided on the side of the sliding square tube 9 away from the electric hoist 7. Fixed plate 13 is used to mount the cleaning device. A deflection push rod 12 is provided on the side of the sliding square tube 9 away from the fixed plate 13. The head of the deflection push rod 12 is transmission-connected to the cleaning device. By extending and retracting the deflection push rod 12, the cleaning device can be deflected and positioned left and right during operation, thereby accurately adjusting the dredging direction.

[0035] The square cross-sectional dimensions of the articulated sleeve 14 and the sliding square tube 9 are consistent and both are larger than the dimensions of the aluminum square tube 1, so that after the lifting link is pulled up to a vertical state, the initial position of the sliding square tube 9 is at the top of the articulated sleeve 14, thereby ensuring that the fixed plate 13 is at a certain height away from the working platform 3, which is convenient for the installation of the dredging robot.

[0036] The main body of the present application is a multi-section lifting connecting rod that can be disassembled, greatly reducing the volume occupied during transportation. The vertical and horizontal states are switched by the electric winch 5, making the installation process easier and reducing the manpower requirements. The cleaning device installation mechanism is driven up and down by the electric hoist 7, driving the dredging robot to rise or descend for cleaning operations, effectively improving the cleaning efficiency. The present application has a simple structure, strong stability, easy assembly and disassembly, and convenient transportation, which can effectively expand the scope of application.

[0037] How it works

[0038] Multiple aluminum square tubes 1 are connected end to end in a horizontal state to form a lifting link. The bottom end of the lifting link is connected to the work platform 3 via a hinged sleeve 14. The rope of the electric winch 5 is wrapped around the reversing column 6 and fixed to the hinged sleeve 14, thereby pulling the lifting link to a vertical state. At this time, the sliding square tube 9 is mounted on the lifting link and located on the top of the hinged sleeve 14. Then, the cleaning device of the dredging robot is installed on the fixed plate 13. The rope of the electric hoist 7 passes from bottom to top around the fixed pulley 8 at the top of the lifting link. By retracting and releasing the rope of the electric hoist 7, the dredging robot can be pulled up or down. By extending and retracting the deflection push rod 12, the cleaning device can be deflected left and right during operation to accurately adjust the dredging direction, thereby accurately completing the cleaning work.
