Description
Technical field
The present invention 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; Life-span arranged side by side like criss-crosss such as cable, gas pipe line, drain hoses, that heat that pipeline produces and aggressive fume have a strong impact on 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, add the weight of itself owing to various situation influences such as well lid pushes through vehicle, and are freezing; Brought great inconvenience for the folding well lid, and the most general method lean on several staff to utilize lever principle with the well lid perk exactly in the prior art, well lid is lifted remove again; 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, and the chain of being with suspension hook is placed on the drive link, through hydraulic efficiency gear chain is promoted, and realizes the lifting of well lid.CN201317648Y discloses a kind of well lid lifting appliance, and the lifting rope of being with suspension hook is spirally wound on the cylinder, impels cylinder to rotate through 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 through 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 received 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 invention is to provide a kind of dismantled and assembled well lid lifting appliance, 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 invention provides a kind of dismantled and assembled well lid lifting appliance, comprising: a cross bar, two hoisting brackets that structure is identical with the function of pulling a cart; Said whippletree upper center is provided with positioning groove, and said whippletree both sides are provided with the positioning sleeve that movably is used for confirming the device span, and said 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; Said 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 said top fixed link is fixed the support framework, and the outside of fixed way was liftoff bottom said two rollers were arranged on; Said whippletree places the position-limited trough of two side stands, confirmed span after, regulate said positioning sleeve, cross bar and two side stands are fixed, the chain sling of two ends band suspension hook is placed the positioning groove of said cross bar.
Each parts of said device are all dismantled and assembled, and the support after disassembling fell the back as pulling a cart loaded with articles, and said roller is used as the wheel of pulling a cart.
Said fluid pressure type jack adopts hand or foot pedal type.
The invention has the beneficial effects as follows the device simplicity of design, each parts is convenient to dismounting, is easy to carry about with one and transports, and support can be used as pulls a cart diverse in function; The construction span is adjustable flexibly, has wide range of applications.
