Abstract

The invention provides a hook for opening well lids. The hook comprises a pull rod and a hook cover. A through hole is formed in the hook cover. The pull rod is movably sleeved with the hook cover through the through hole. The pull rod can move up and down relative to the hook cover. A plurality of notches are formed in the opening of the lower end of the hook cover at equal intervals. Hook heads are arranged in the notches respectively and are fixedly connected through a connection ring. A supporting block used for propping the hook heads open is arranged at the tail end of the pull rod. A connection rope is arranged at the upper end of the pull rod. The supporting block is in the shape of a sphere or a cone, and the maximum diameter of the sphere or the cone is larger than the diameter of the through hole of the hook cover. The hook has the beneficial effects that the well lids can be lifted reasonably and effectively through the hook, the situation that since the well lids are not well hooked, the well lids are damaged or fall on feet is avoided, and the hook is very convenient to use, simple in structure, low in manufacturing cost and suitable for various well lids.

Description

A kind of hook for the lid that drives a well

Technical field

The present invention relates to a kind of hook, particularly a kind of hook for the lid that drives a well.

Background technology

In the road administration in urban district, general employing is circular, because the well lid of circle not easily tilts, the safety of pedestrian and vehicle can be protected preferably, utilize with cable shaft in the country, general employing is square, like this can the entering of the liquid such as pre-rainwater-proof better, but well lid is opened now is all adopt manually to have been dug by well lid substantially, requires great effort very much, and fragile well lid, very inconvenient;

The applicant has applied for that patent name is a kind of well cover opening device early stage, and during this device open manhole cover, well lid easily drops, inconvenient, so need a kind of hook being mated the lid that drives a well of use just can address these problems.

Summary of the invention

For existing technical deficiency, the invention provides a kind of hook for the lid that drives a well.

To achieve these goals, the technical solution used in the present invention is: a kind of hook for the lid that drives a well, comprise pull bar and rhampotheca, described rhampotheca is provided with through hole, and rhampotheca is actively socketed on pull bar by through hole, and described pull bar can relative to rhampotheca up-and-down movement, described rhampotheca lower ending opening place is provided with the equal otch of some spacing, be equipped with gib head in described otch, and be connected and fixed by coupling link, described pull bar end is provided with the back-up block for strutting gib head.

Described pull bar upper end is provided with connection cord.

Described back-up block is spheroidal or taper shape, and spheroidal or cylindrical-conical maximum gauge are greater than the diameter of rhampotheca through hole.

Beneficial effect of the present invention: the design can rationally actv. be by well lid pull-up, and pin can not be broken or be pounded to well lid because of not having hook good, very easy to use, structure is simple, and cost of manufacture is low, is applicable to various well lid.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is use shape body schematic diagram of the present invention.

Detailed description of the invention

As shown in Fig. 1 ~ Fig. 2, a kind of hook for the lid that drives a well, comprise pull bar 1 and rhampotheca 2, described rhampotheca 2 is provided with through hole, and rhampotheca 2 is actively socketed on pull bar 1 by through hole, and described pull bar 1 can relative to rhampotheca 2 up-and-down movement, described rhampotheca 2 lower ending opening place is provided with the equal otch of some spacing, be equipped with gib head 3 in described otch, and be connected and fixed by coupling link, described pull bar 1 end is provided with the back-up block 4 for strutting gib head 3.

Described pull bar 1 upper end is provided with connection cord 5.

Described back-up block 4 is spheroidal or taper shape, and spheroidal or cylindrical-conical maximum gauge are greater than the diameter of rhampotheca through hole.

When using this device, first this device is in the raw put into the hole of well lid, then apply a pulling force upwards to pull bar, the back-up block tension power effect upward movement of pull bar lower end, struts some gib heads, thus reaches the object mentioning well lid.
