Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Referring to fig. 1 to 6, a portable manhole cover lifting device according to an embodiment of the present invention includes a supporting rod 10, a swinging rod 20 rotatably connected to the supporting rod 10, and a lifting rod 30.

In this embodiment, the swing rod 20 of this embodiment is articulated to have a connecting sleeve 40 in one side tip that stretches out the bracing piece 10, and the lifting rod 30 runs through connecting sleeve 40 and sets up, and wherein the one end that the lifting rod 30 upwards stretches out connecting sleeve 40 is provided with spacing dog 31, and spacing dog 31 can support and lean on in connecting sleeve 40 to limiting lifting rod 30 on connecting sleeve 40, the one end that the lifting rod 30 stretches out connecting sleeve 40 downwards is provided with well lid fitting piece 50, and lifting rod 30 can act on well lid 200 through well lid fitting piece 50. It should be noted that the lifting rod 30 can sink relative to the connecting sleeve 40 under the action of its own gravity until being limited by the upper limit stopper 31 of the lifting rod 30.

Therefore, when the portable well lid lifting device works, the support rod 10 can be abutted against the ground 300, so as to support the portable well lid lifting device on the ground 300, then the swing rod 20 is driven to move on the support rod 10, the swing rod 20 drives the lifting rod 30 to move the well lid fitting piece 50 downwards to the lower side of the well lid 200 through the connecting sleeve 40, the well lid fitting piece 50 is limited upwards on the well lid 200 in a manner of driving the lifting rod 30 to rotate for 90 degrees, then the other end of the swing rod 20 is pressed downwards, so that the part of the swing rod 20 connected with the connecting sleeve 40 can drive the lifting rod 30 to ascend, the well lid fitting piece 50 on the lifting rod 30 lifts the well lid 200, and the lifting drive of the portable well lid lifting device to the well lid 200 is realized.

The position of the swing rod 20 connected to the support rod 10 of the present embodiment is provided with a pin 101, and the swing rod 20 is rotatably connected to the support rod 10 through the pin 101, so as to realize the rotatable connection between the support rod 10 and the swing rod 20, and the structure is simplified, so as to facilitate the assembly and connection between the swing rod 20 and the support rod 10.

The distance between the end of the swing rod 20 connected with the connecting sleeve 40 and the plug 101 is smaller than the distance between the end of the swing rod 20 at the other end and the plug 101, so that when the portable manhole cover lifting device works, the manhole cover 200 can be lifted by the connecting sleeve 40 and the lifting rod 30 when the swing rod 20 is pressed down by using the principle of a lever.

It can be understood that, because the swinging arms 20 can drive the well lid 200 to move simultaneously when rotating on the supporting rod 10, because the swinging arms 20 can drive the connecting sleeve 40 to perform circular arc motion, when the well lid 200 is lifted by the connecting sleeve 40 and the lifting rod 30, the well lid 200 can be driven to move towards the supporting rod 10, and the well lid 200 is lifted to the ground 300.

In the present embodiment, the pressing conical head 11 is disposed at one side end of the supporting rod 10 facing the ground 300, and the supporting rod 10 can act on the ground 300 through the pressing conical head 11, so as to improve the stability of the supporting rod 10 acting on the ground 300.

In addition, the distance between the pressing cone 11 and the plug 101 is smaller than the distance between the other end of the support rod 10 and the plug 101. When the portable well lid lifting device works, the lifting driving of the well lid 200 can be realized through the swinging motion of the driving supporting rod 10 and the swinging rod 20, the connecting sleeve 40 and the lifting rod 30.

In this embodiment, the lifting rod 30 of this embodiment is in clearance fit with the connecting sleeve 40, and the lifting rod 30 can rotate 90 ° relative to the connecting sleeve 40, so as to meet the use requirement when the lifting rod 30 acts on the well lid 200.

In this embodiment, the limit stopper 31, the lifting rod 30 and the manhole cover fitting piece 50 of this embodiment are arranged as an integrated structure, so as to facilitate the production and preparation of the lifting rod 30.

The well lid fitting 50 of the present embodiment includes two protruding pieces, and the two protruding pieces are symmetrically fixed on the lifting rod 30 to be adapted to the waist-shaped hole 201 on the well lid 200.

In summary, when the portable manhole cover lifting device of the present embodiment works, when the manhole cover engaging member 50 on the lifting rod 30 engages with the manhole cover 200, the downward pressing of the oscillating rod 20 and the oscillating movement of the supporting rod 10 can be alternatively operated to lift one side of the manhole cover 200 acted by the manhole cover engaging member 50 on the lifting rod 30 away from the wellhead and lift the side onto the ground 300, so as to facilitate the removal of the manhole cover 200 from the wellhead; meanwhile, the portable well lid lifting device is simple in structure, convenient to operate and capable of being integrally folded so as to further meet the use requirements of people.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
