The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The utility model provides a municipal pipeline manhole cover lifting device, such as Figure 1-Figure 5 As shown, the municipal pipeline manhole cover lifting device comprises:

[0026] A main frame 100, the main frame 100 comprises a bottom frame 110 and a top frame 120, the top frame 120 is provided with a support plate 130 for arranging the lifting and lowering equipment; the bottom frame 110 is provided with a guide rail for limiting and guiding the supporting equipment;

[0027] The sliding support plate 200 includes a main plate body 210 and an upper slide plate 230. Both sides of the main plate body 210 slide on the bottom frame 110. The upper slide plate 230 extends from the bottom frame 110 to the outside of the bottom frame 110.

[0028] The lifting and traction equipment 300 is a set. The lifting and traction equipment 300 uses a conventional winch as a lifting and lowering device. The figure only shows the core components and related auxiliary fixed bearings and cables. The technical personnel in this field can refer to the existing mature winch equipment for the specific structure. The winch uses the cable and the hook at the front end of the cable to pull the manhole cover 400. When the manhole cover 400 is lifted, the sliding support plate 200 is pushed to reach the gap between the manhole cover 400 and the manhole body, and then the manhole cover 400 is put down so that it is laid flat on the sliding support plate 200, and the sliding support plate 200 supports the manhole cover 400.

[0029] The bottom of the bottom frame 110 and the bottom of the sliding support plate 200 are both provided with universal wheels. Before lifting, the main frame 100 is moved above the manhole cover 400, and the lifting and traction equipment 300 is used to pull the opening hole at one end of the manhole cover 400 with the help of the hook. Since one end of the manhole cover 400 is subjected to force, it will be lifted and tilted under the action of the traction force. At this time, the sliding support plate 200 is lifted from the manhole cover 400 and one end is pushed under the manhole cover 400, and then the manhole cover 400 is put down, so that part of the structure of the manhole cover 400 falls on the sliding support plate 200. Under the action of the lever principle, the manhole cover 400 will also be separated from the manhole during the placement process because the end that is lifted is not lifted.

[0030] In the present application, the lifting and traction device 300 adopts existing mature equipment as the traction power source, and the movable sliding pallet 200 acts as a supporting component. When the manhole cover 400 falls on the sliding pallet 200, the manhole cover 400 can be freely moved away from the manhole with the help of the universal wheel, reducing the operation of manual lifting and manual handling during the entire operation process, thereby improving the opening efficiency of the manhole cover 400;

[0031] It should be noted that in the present application, there is no hinged connection between the manhole cover 400 and the manhole, and it is mainly a heavy-duty split manhole cover 400. The sliding support plate 200 is mainly used to lift the manhole cover 400 after opening, and there is no need to lift the flip-type manhole cover 400. The present application can also open the flip-type manhole cover 400, and when the lifting and traction equipment 300 is pulled up, the main frame 100 is pushed synchronously to open it. This process does not require the intervention of the sliding support plate 200;

[0032] As a preferred implementation in this embodiment, the bottom frame 110 includes two sets of guide frames 111, a limit frame 112 and a rear frame 113; the guide frames 111 are arranged in parallel, and the limit frame 112 and the rear frame 113 are connected to both ends of the guide frame 111;

[0033] The guide frame 111 is provided with a guide groove 114, and the middle section of the limit frame 112 is provided with a limit slide groove; the side slider 220 provided on the side wall of the main body 210 slides along the limit slide groove, and the upper slide plate 230 slides in the limit slide groove; the side slider 220 abuts against the end surface of the guide groove 114 facing the ground, and the upper slide plate 230 is pressed against the end surface of the limit slide groove facing the top frame 120;

[0034] In this embodiment, the bottom frame 110 limits the sliding support plate 200 with the help of the guide groove 114 and the limiting sliding groove to prevent the sliding support plate 200 from being separated from the bottom frame 110 during the lifting process;

[0035] As a preferred implementation in this embodiment, the lifting and traction devices 300 are two sets, and the lifting and traction devices 300 are respectively connected to the two opening holes of the manhole cover 400 through cables and hooks. When the two sets of lifting and traction devices 300 move at the same time, the manhole cover 400 will rise horizontally. When the manhole cover 400 is suspended in the air, the sliding support plate 200 is immediately pushed under the manhole cover 400, and then the lifting and traction devices 300 put down the manhole cover 400 and the sliding support plate 200 lifts it.

[0036] As a preferred implementation in this embodiment, a screw hole is provided at the end of the upper slide plate 230 away from the main body 210, and a positioning screw hole is provided on the limiting slide groove; after the sliding support plate 200 completes lifting the manhole cover 400, the upper slide plate 230 is pushed so that the screw hole and the positioning screw hole are connected, and the limiting bolt is used for fixed connection, and the sliding support plate 200 and the main frame 100 form an integral structure for movement;

[0037] When the side slide block 220 slides to the end of the guide groove 114, the edge of the upper slide block 230 remains flush with the outer edge of the limit frame 112, ensuring that the sliding support plate 200 does not slip off the main frame 100;
