Description

Pull laborsaving well lid car of opening of formula

Technical Field

The utility model relates to a well lid opening device specifically is a pull laborsaving well lid car of opening of formula.

Background

As an infrastructure, an urban pipe network plays an important role in urban development and production and life of people, every section of pipelines needs to be provided with an inspection well which leads to the ground, the pipelines are covered by a well cover in normal times, and before the pipelines are inspected and maintained, people need to open the well cover of the inspection well. At the present stage, the well opening cover is generally opened manually by using crowbars, ocean pickaxes and the like. When the well lid was not opened for a long time, had debris such as silt to fill into (perhaps rolled deformation by the car between its well lid and the well hoop, blocked the well hoop), constructor need use very energetically just can open the well lid this moment, not only wastes time and energy, can form the harm to constructor lumbar vertebrae moreover, probably can cause relevant occupational disease even.

Disclosure of Invention

To the problem that exists among the above-mentioned prior art, the utility model provides a convenient to use is laborsaving pulls formula laborsaving and opens well lid car reduces the intensity of labour that the well lid was opened to the constructor.

The utility model adopts the technical scheme as follows: the utility model provides a pull formula laborsaving well lid car, includes the frame body, the walking wheel is installed to frame body bottom, the vertical lead screw that is provided with in frame body middle part, both ends respectively with the frame body rotates to be connected about the lead screw, the upper end of lead screw is connected with and is used for driving lead screw pivoted drive arrangement, threaded connection has screw-nut on the lead screw, screw-nut and lifting by crane a set fixed connection, it is connected with the chain of taking T shape hook to play the hanging scaffold bottom.

Further, a plurality of guide rods are fixedly mounted on the frame body, the guide rods are arranged in parallel with the screw rod, and the hoisting plate is in sliding fit with the guide rods.

Further, the driving device is a hand crank or a driving motor.

Further, the number of the chains with the T-shaped hooks is two.

Furthermore, the front end of the frame body is connected with a traction frame.

The utility model discloses a laborsaving well lid car of opening of pull formula only needs to use car or tricycle to pull this equipment to well lid top, then inserts the hole of well lid with the terminal T shape hook of chain, then makes its card in the hole with T shape hook rotation 90, then drives the lead screw and rotates, drives through screw-nut and rises the platform sling, makes the well lid not hard up and finally mentions the well lid, then turns over it through the manual work again. Through the device, the labor intensity of constructors can be reduced, and the risk of occupational diseases is reduced.

Fig. 2 is a schematic view of the usage state of the present invention.

Detailed Description

To facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the specific embodiments described below.

As shown in fig. 1, the well lid car is opened to drag formula laborsaving of this embodiment, including the frame body 1, walking wheel 2 is installed to frame body 1 bottom, and the front end of frame body 1 is connected with traction frame 8, can be connected with car or tricycle through traction frame 8, is convenient for it to remove. The vertical lead screw 4 that is provided with in 1 middle part of the frame body, lead screw 4 about both ends respectively with 1 rotates the frame body and is connected, still is connected with in the upper end of lead screw 4 and is used for driving 4 pivoted cranks 3 of lead screw, threaded connection has screw-nut 6 on the lead screw 4, screw-nut 6 with lift by crane a set 7 fixed connection, go back fixed mounting on the frame body 1 and have many guide bars 5, guide bar 5 with 4 parallel arrangement of lead screw, lift by crane set 7 with 5 sliding fit of guide bar. Two hanging rings are arranged at the bottom of the lifting disc 7, and chains 9 with T-shaped hooks are respectively connected to the two hanging rings.

As shown in fig. 2, during the use, will pull laborsaving well lid car of opening of formula through car or tricycle and pull to well lid 10 top, then insert T shape hook in the hole of well lid 10 (resin well lid generally has two holes, need insert simultaneously this moment, cast iron well lid generally has only a hole, its other side generally is the hinge, only need insert a hole this moment), then make its card in the hole with the rotatory 90 of T shape hook, artifical rotatory crank again, it rises to drive hoisting plate 7 through screw-nut 6, make the well lid not hard up and finally lift well lid 10, then turn over it again through the manual work and open.

Many modifications and other embodiments of the invention will come to mind to one skilled in the art to which this invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
