Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer to shown in Fig. 1-5：
A kind of lifting device of town road well lid of the present embodiment, it includes portal frame 1 and lifts arm, and lifting arm includes
Arranged in a crossed manner first lifts arm 2a, second lifts arm 22b.
Above-mentioned portal frame 1 is made up of two legs 14 of the rounded cross bar 10 in section and connection cross bar 10 two ends, cross bar
10 middle parts are arranged with the sleeve pipe 11 that can be rotated along the side face of cross bar 10.Meanwhile, the middle part of cross bar 10 is provided with a pair of limiting boots 11 along horizontal stroke
The spacing block piece 12 in axial sliding of bar 10, sleeve pipe 11 is limited between spacing block piece 12, can not slide axially, but can be along cross bar
10 circumferentially rotate.The outside of sleeve pipe 11 is fixedly arranged in the middle of hinged seat 25, and first lifts arm 2a and second lifts arm 2b middle parts infall
It is hinged on hinged seat 25.
Above-mentioned first lifts arm 2a and the second front end for lifting arm 2b is equipped with the carrying up component 20 for extending downwardly from, and lifts structure
The lower end of part 20 is provided with the fastener 21 coordinated with the hole on well lid 3.The upper end of carrying up component 20 is rotatably connected with arm front end is lifted.The
One lifts arm 2a and the second rear end for lifting arm 2b is equipped with handle 27.Wherein first lifts arm 2a and second lifts arm 2b front ends
Distance to infall is less than infall to the distance of rear end, so meets the principle of lever force-saving.
As shown in figure 4, lifting arm front end is provided with installation shoulder hole, all portions of the upper end of carrying up component 20 offer annular groove
23, the upper end of carrying up component 20 is stretched into the installation shoulder hole for lifting arm front end.Shoulder hole step is installed upward, spring 24 is located at ring
Connected in star 23 and install in the spring retention space that surrounds of shoulder hole, the lower end of spring 24 is pressed on the installation shoulder hole that lifts arm
On step, upper end is pressed on the cell wall of annular groove 23 of carrying up component 20.The top of carrying up component 20 is provided with knob 22, such one
Come, can with friction adjust the direction of fastener 21, make fastener 21 motionless because being maintained at a direction and position with friction.
After the direction of fastener 21 determines, it is not necessary to adjust, only need to open first when using and lift arm 2a and second and lift arm 2b, make
Fastener 21 directly snap in the through hole 31 of town road well lid 3 can be to use.Certainly, the mode that fastener 21 is set is a lot, most
It is simply T-shaped fastener as shown in Figure 4.
The lower end of two legs 14 on above-mentioned portal frame 1 is equipped with roller 15, and roller 15 is provided with brake gear 15a,
There is roller 15 to be advantageous in that the carrying for facilitating town road well lid 3, direct image go-cart is the same, allow the load-bearing of portal frame 1, use effect
Fruit is very good.
As shown in figure 5, this case using very simple, need only lift arm 2a and second by first and lift arm 2b and open, yes
Through hole 31 on two fasteners 21 and town road well lid 3 is adapted to, you can completion lifts.
Releasing of brake device 15a, is pushed away before holding handle, you can town road well lid 3 is removed in transport.For this case,
Those skilled in the art have many general knowledge, such as, the width of portal frame 1 is greater than the diameter of town road well lid 3, and this is aobvious
And be clear to.Auditor can not be because of the common-sense details not limited, and to illustrate this case insufficient disclosure.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be in other specific forms realized.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires to be limited rather than described above, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined
