Description
Technical field
The utility model relates to a kind of hanging apparatus, particularly a kind of dismantled and assembled well lid lifting appliance.
Background technology
Needs according to urban infrastructure, the laying project of underground utilities increases day by day, because underground utilities all are embedded in underground, arranged side by side as criss-crosss such as cable, gas pipe line, drain hoses, heat and aggressive fume that pipeline produces have a strong impact on the life-span of underground utilities easily, even cause failure accident.For fear of the generation of above-mentioned situation, municipal sector needs the periodic inspection underground utilities, need carry earlier before the maintenance and open well lid.But because well lid is through the vehicle extruding, various situations influence such as freezing, add the weight of itself, brought great inconvenience for the folding well lid, and the most general method utilizes lever principle with the well lid perk by several staff exactly in the prior art, again well lid is lifted and remove, retract original position after the maintenance, so repeatedly, not only consuming time but also consume power, it is bad not only easily well lid to be prized rhegma, also may produce as squeeze personal injuries such as hand has one's foot squashed to the staff.
CN201172616Y discloses a kind of well lid lifting appliance, with being with the chain of suspension hook to place on the drive link, by hydraulic efficiency gear chain is promoted, and realizes the lifting of well lid.CN201317648Y discloses a kind of well lid lifting appliance, will be with the lifting rope of suspension hook to be spirally wound on the cylinder, impels cylinder to rotate by hand turbine, and cylinder rotates and makes the lifting rope contraction in length, realizes the lifting of well lid.Said method has all been realized the purpose by the mechanical lifting well lid, has saved certain manpower.But the said apparatus complex structure, each parts is not removable, the not portable and preservation of package unit; In addition, because above-mentioned lifting appliance relative fixed, therefore the span of device is fixed, and the size that can not be used for well lid surpasses the lifting construction of this device span, and field of application has been subjected to great constraint.Therefore, need a kind of easy accessibility, the construction span is adjustable well lid lifting appliance flexibly.
Summary of the invention
The purpose of this utility model provides a kind of dismantled and assembled well lid lifting appliance, and this installs each parts easy accessibility, be easy to carry about with one and preserve, and the construction span is adjustable flexibly, can be applicable to the well lid lifting construction under the various conditions.
The utility model provides a kind of dismantled and assembled well lid lifting appliance, comprise: a cross bar, two hoisting brackets that structure is identical with the function of pulling a cart, described whippletree upper center is provided with hold down groove, and described whippletree both sides are provided with the positioning sleeve that movably is used for determining the device span, described support has the bottom fixed way, the fluid pressure type jack, jack fixed strip, support framework, the radius stay of band position-limited trough, top fixed link and two rollers; Described jack bottom is fixed on the fixed way of bottom, the middle part of jack is fixed on the support framework by the jack fixed strip, jack top connects radius stay, and described top fixed link is fixed the support framework, and the outside of fixed way was liftoff bottom described two rollers were arranged on; Described whippletree places the position-limited trough of two side stands, determined span after, regulate described positioning sleeve, cross bar and two side stands are fixed, the chain sling of two ends band suspension hook is placed the hold down groove of described cross bar.
Each parts of described device are all dismantled and assembled, and the support after disassembling fell the back as pulling a cart loaded with articles, and described roller is used as the wheel of pulling a cart.
Described fluid pressure type jack adopts hand or foot pedal type.
The beneficial effects of the utility model are device simplicity of design, and each parts is convenient to dismounting, are easy to carry about with one and transport, and support can be used as pulls a cart diverse in function; The construction span is adjustable flexibly, has wide range of applications.
