DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0019] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 3 As shown, a lifting device for a decorative manhole cover includes a fixed platform 14, an electric cylinder 3 and a sliding assembly 4. The fixed platform 14 is fixedly connected to the outer wall of the valve well 1. A plurality of ribs 13 are arranged between the bottom surface of the fixed platform 14 and the outer wall of the valve well 1. The ribs 13 are circumferentially distributed along the bottom surface of the fixed platform 14 and are evenly spaced. The ribs 13 can improve the load-bearing capacity of the fixed platform 14 and slow down the deformation of the fixed platform 14 in the vertical direction. A plurality of electric cylinders 3 are arranged on the top of the fixed platform 14, and the telescopic ends of the electric cylinders 3 are fixedly connected to the bottom surface of the sliding assembly 4. A group of sliding assemblies 4 symmetrically distributed on both sides of the wellhead are arranged above the fixed platform 14, and electric cylinders 3 are arranged at both ends of the bottom of the sliding assembly 4. The sliding assembly 4 includes a slide 41 and a moving member 42. One end of the slide 41 is open, and a limit plate 411 is arranged at the other end. The moving member 42 is embedded in the slide 41 and wheels 421 are arranged at both ends. The wheels 421 are in contact with the bottom of the slide 41. The top surface of the moving part 42 is provided with a plurality of positioning pins 422, and the bottom surface of the manhole cover 2 is provided with positioning holes that match the positioning pins 422. The detachably connected manhole cover 2 and the moving part 42 facilitate the disassembly of the manhole cover 2. The sliding part moves along the slide 41, and the limit plate 411 facilitates the moving part 42 to move the manhole cover 2 to the top of the wellhead, and the wheel 421 reduces the friction between the moving part 42 and the slide 41. A locking mechanism is provided in the middle of the sliding assembly 4, and the locking mechanism includes a fixing plate 412, a protrusion 423 and a fixing bolt 413. A fixing plate 412 is provided in the middle of one side of the slide 41, and a protrusion 423 is provided in the middle of the top surface of the moving part 42. A through hole is provided on the fixing plate 412, and a threaded hole is provided at the position of the protrusion 423 corresponding to the through hole, and the fixing bolt 413 passes through the through hole and is screwed into the threaded hole. When one end of the moving member 42 is in contact with the stop plate 411, the through hole and the threaded hole are exactly concentric, and the fixing bolt 413 fixes the moving member 42 to the slide slot 41. The electric cylinder 3 drives the sliding assembly 4 to move up and down. When the sliding assembly 4 drives the manhole cover 2 to be lifted to a distance away from one end of the wellhead, the fixing bolt 413 is unscrewed, so that the moving member 42 moves out along the open end of the slide slot 41, and the manhole cover 2 leaves the top of the wellhead.

[0021] An electrical module 12 is provided on the fixed platform 14, and a control circuit is provided in the electrical module 12. Multiple electric cylinders 3 are electrically connected to the same control circuit, so that multiple electric cylinders 3 can work or stop at the same time, ensuring that the manhole cover 2 remains stable when it is lifted or lowered. The control circuit is provided with a remote control receiver, which can receive signals outside the manhole cover 2 and send control signals to the control circuit through an external remote control device. A wellhead is provided at the top of the valve well 1, and a rubber ring 11 is provided at the edge of the wellhead. The top surface of the rubber ring 11 contacts the bottom surface of the manhole cover 2. The rubber ring 11 forms a buffer layer between the wellhead and the manhole cover 2 to prevent rigid collision from causing damage to the manhole cover 2 or the wellhead.

[0022] The working principle of the specific embodiment of the utility model is as follows: when the manhole cover 2 needs to be raised, a start signal is sent to the electrical module 12 through an external remote controller, and the telescopic end of the electric cylinder 3 extends to push the sliding assembly 4 and the manhole cover 2 out a certain distance. The fixing bolt 413 is unscrewed to push the moving member 42 along the open end of the slide slot 41, so that the manhole cover 2 is away from the top of the wellhead.
