As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] like Figures 1 to 5 As shown, this embodiment provides a slope membrane lifting mechanism for a hazardous waste landfill, comprising a plurality of pulling components 3 located on a horizontal ground 2 on a high side of a slope 1, wherein the pulling components correspond one to one with a plurality of anti-seepage membranes 4 spliced ​​and covered on the upper surface of the slope;

[0024] The pulling components all include a mobile cart 5, to which a winch 6 is fixedly connected. One end of a pulling rope 7 wound on the reel of the winch is tied and connected to the corresponding lower side of the anti-seepage membrane. A positioner is provided on the side of each mobile cart on the horizontal ground on the high side of the slope.

[0025] In an embodiment of the utility model, the anti-seepage membranes are laid along a part of the horizontal ground on the high side of the slope to the lowest side of the slope, and adjacent anti-seepage membranes are connected and spliced ​​at their long sides, and the distance between the pulling assembly and the highest point of the slope is greater than the slope length of the slope.

[0026] In the embodiment of the utility model, a plurality of universal casters 8 with brakes are installed on the bottom surface of the mobile cart.

[0027] In the embodiment of the utility model, the lower side of the anti-seepage membrane is fixedly connected with a rigid pipe 9, and the rigid pipe is arranged along the width direction of the lower side of the anti-seepage membrane.

[0028] In the embodiment of the utility model, a circular ring 10 is fixedly provided on the upper outer periphery of the rigid pipe, and the pulling rope is tied to the circular ring.

[0029] In the embodiment of the utility model, the positioner includes two columns 11 vertically fixed on the horizontal ground. The back of the mobile cart away from the pulling rope is connected to a circular positioning ring 12 with a vertical axis through a vertical slider and rail moving pair. The circular positioning ring corresponds to the column one by one and is sleeved on the outer periphery of the column, and the circular positioning ring is evenly distributed with a plurality of fixing screws 13 on the circumference. The fixing screws are radially screwed to the circular positioning ring and tighten the column. The slider 14 in the slider and rail moving pair used to be fixedly connected to the circular positioning ring is also screwed with a fixing screw for tightening the rail 15.

[0030] In the embodiment of the utility model, each group of pulling components includes two moving carts, and the two moving carts are symmetrically arranged along the width direction of the corresponding anti-seepage membrane.

[0031] In the embodiment of the utility model, the working principle of the slope membrane lifting mechanism of the hazardous waste landfill is as follows: the slope membrane lifting mechanism of the hazardous waste landfill replaces manual membrane lifting by setting up several groups of pulling components, and each anti-seepage membrane has a corresponding pulling component. The mobile cart located on the horizontal ground on the high side of the slope can gradually pull the anti-seepage membrane from the low side to the high side through a winch and a pulling rope, thereby realizing the lifting of the anti-seepage membrane, saving manpower and improving work efficiency.

[0032] Specifically, during operation, the mobile cart is first moved to the positioner, and by adjusting the height of the circular positioning ring on the mobile cart, the circular positioning ring is matched with the column one by one and is sleeved on the outer periphery of the column, and finally the fixing screws between the circular positioning ring and the column, as well as the fixing screws on the sliding block and the slide rail moving pair are locked to achieve temporary positioning of the mobile cart. Then the staff pulls one end of the pulling rope on the winch downward and ties it to the circular ring of the rigid pipe on the lower side of the corresponding anti-seepage membrane, and then gradually pulls the corresponding anti-seepage membrane from the lower side of the slope to the higher side of the slope through the winch and the pulling rope. During the pulling process, the lower side of the anti-seepage membrane becomes located on the upper surface of the anti-seepage membrane, that is, the pulling side of the anti-seepage membrane is rolled into a U shape. Since "the distance between the pulling component and the highest point of the slope is greater than the slope length of the slope", the anti-seepage membrane of the slope can be completely lifted. After the slope is completely lifted, the position of the anti-seepage membrane located on the horizontal ground portion remains unchanged, while the lower side of the anti-seepage membrane of the slope is pulled close to the winch.

[0033] Each pulling assembly includes two mobile carts, and the two mobile carts are symmetrically arranged along the width direction of the corresponding anti-seepage membrane. When lifting the membrane, the winches of the two mobile carts of each pulling assembly pull synchronously at a uniform speed, which can ensure that each anti-seepage membrane remains balanced and difficult to tilt during the lifting process.

[0034] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
