Description

Technical Field

[0001] The utility model relates to the field of lifting tools, in particular to a lifting tool specially used for invisible manhole covers. Background Art

[0002] With the continuous improvement of the level of urban construction infrastructure, urban road sidewalks are generally upgraded to granite paving, and the style requirements for pipeline manhole covers are also upgraded to invisible manhole covers. Invisible manhole covers have the function of beautifying urban infrastructure, but they are also bulky and cannot be opened by one person, which increases the difficulty of workers when inspecting valves or reading meters. In most cases, only one person participates in the inspection and maintenance of pipelines, and opening invisible manhole covers becomes a major problem. For this reason, we propose a special lifting device for invisible manhole covers. Utility Model Content

[0003] The purpose of the utility model is to provide a special lifting device for invisible manhole cover to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special lifting device for invisible manhole covers, including a hydraulic lifting forklift, a lifting mechanism is installed on the surface of the hydraulic lifting forklift, and the lifting mechanism includes two groups of lifting blocks installed on the surface of the hydraulic lifting forklift, the upper end surfaces of the two groups of lifting blocks are fixedly connected with mounting blocks, a sleeve is installed between the two groups of mounting blocks, both ends of the sleeve are threadedly installed with telescopic tubes, the two groups of telescopic tubes are adaptively inserted in the two groups of mounting blocks, and the outer ends of the two groups of telescopic tubes are installed with lifting rods.

[0005] Preferably, the suspension rod is arranged in a "T" shape or a "J" shape.

[0006] Compared with the prior art, the beneficial effects of the utility model are: this solution can lift and open invisible manhole covers of different types and lengths through the structural setting of the hydraulic lifting forklift and the lifting mechanism, and the device can be operated by a single person, which greatly reduces manpower and solves the difficulty of opening, saving water meter reading time and labor during maintenance.

[0010] Example

[0011] See also Figure 1-2 , the utility model provides a technical solution:

[0012] A special lifting device for invisible manhole cover, a detachable lifting mechanism 2 is installed on the surface of a hydraulic lifting forklift 1. When in use, after the lifting mechanism 2 is assembled above the invisible manhole cover, the hydraulic lifting forklift 1 is moved to the bottom of the lifting mechanism 2 and the lifting mechanism 2 is loaded, and the hydraulic lifting forklift 1 is further controlled to rise, so as to drive the lifting mechanism 2 to rise and lift the invisible manhole cover, thereby realizing the opening of the invisible manhole cover. In addition, through the use of this device, the actual opening difficulties of the staff can be reduced, and the operation can be completed by a single person, which greatly reduces manpower and solves the difficulty of opening, saving water meter reading time and labor during maintenance.

[0013] The lifting mechanism 2 includes two groups of lifting blocks 201 installed on the hydraulic lifting forklift 1. The lifting blocks 201 are set to a "U"-shaped structure. When in use, the two groups of lifting blocks 201 are placed at both ends of the surface of the invisible manhole cover according to the diameter of the invisible manhole cover. By moving the hydraulic lifting forklift 1 above the invisible manhole cover and inserting the two groups of fork plates of the hydraulic lifting forklift 1 under the two groups of lifting blocks 201, the hydraulic lifting forklift 1 can lift the lifting mechanism 2 during the lifting process. The upper end surfaces of the two groups of lifting blocks 201 are fixedly connected with mounting blocks 202, and sleeves 203 are installed between the two groups of mounting blocks 202. Both ends of the sleeves 203 are threadedly inserted with telescopic tubes 204, and the two groups of telescopic tubes 204 are inserted in the two groups of mounting blocks 202 in an adaptive manner. Further, when the hydraulic lifting forklift 1 lifts the two groups of lifting blocks 201, the sleeves 203 and the telescopic tubes 204 can be lifted as a whole. The outer ends of the two sets of telescopic tubes 204 are fixedly connected with a suspension rod 205, which is further inserted into the holes on the surface of the invisible manhole cover, so that the lifting mechanism 2 can lift the invisible manhole cover through the suspension rod 205 during the lifting process, thereby further realizing the rapid opening of the invisible manhole cover.

[0014] And as the distance between the two sets of lifting blocks 201 is adjusted, the telescopic tube 204 is rotated inside the sleeve 203 to adjust the overall length of the sleeve 203 and the telescopic tube 204, so that the device can be applied to invisible manhole covers of different lengths, thereby improving the practicality and practicability of the device.

[0015] The lifting mechanism 2 is provided in two groups, and the front-rear spacing of the two groups of lifting mechanisms 2 on the hydraulic lifting forklift 1 is adjustable to be suitable for invisible manhole covers of different types and to improve the stability and safety of the lifting mechanism 2 when lifting the invisible manhole cover.

[0016] The suspension rod 205 is provided in two types, namely, a "T" shape and a "J" shape, so as to be suitable for different invisible manhole cover surface openings, meet the needs of opening different types of invisible manhole covers, and improve the practicality and applicability of the device. The suspension rod 205 can also be installed on the surface of the telescopic tube 204 using a chain structure, which further facilitates the flexible adjustment of the direction of the suspension rod 205 when in use.
