Description

Novel attachment type raise scaffold

Technical field

The utility model relates to the scaffold production technical field, especially relates to the raise scaffold that is used for highrise building.

Background technology

Builing industry extensively adopts attachment type raise scaffold in construction engineerings such as reinforced concrete structure highrise building, bridge protection, chimney king-post.Attachment type raise scaffold mainly comprises frame structure, jacking system and electrical apparatus control system three parts.Wherein, frame structure is made up of vertical framework and connection framework etc.; Jacking system is made up of attached support structure, elevating mechanism.Vertical framework inboard in the frame structure is provided with guide rail.Guide rail matches with leading anti leaning equipment, plays guiding and anti-dumping effect; Under working condition, leading anti leaning equipment, falling proof device etc. is installed on the attached support structure, and usually attached support structure adopts through-wall bolt to be installed in the building structure, and with the various loading transfer of frame structure to building structure.Attached lift scaffold is all realized lifting by jacking equipment.

But present attached lift scaffold exists more or less still that overall structure is unreasonable, and safety has certain hidden danger, defectives such as running stability difference.

The utility model content

The purpose of this utility model provides a kind of novel attachment type raise scaffold of rational in infrastructure, safe and reliable, operational excellence.

The purpose of this utility model is achieved through the following technical solutions: novel attachment type raise scaffold, comprise supporting arrangement, frame structure, jacking equipment and safety guard, and frame structure comprises horizontal tray, vertical framework; Horizontal tray is connected with vertical base of frame; Vertical framework is connected with supporting arrangement, supporting arrangement is connected on the building by through-wall bolt, supporting arrangement is provided with lifting appliance, anti-tilt device and anti-drop device, vertical framework is provided with guide rail, guide rail is restricted by guide wheel group, rely on building to fix and promote, it is characterized in that: the guide wheel of guide wheel group contacts for the elasticity extrusion rolling with guide rail.

The utility model also can further be realized by following scheme:

The structure of described guide wheel group is: wheel frame is the rectangle cell body, on be installed with the guide wheel shaft of several horizontal distribution, the outer end of guide wheel shaft is fixed by bolt, guide wheel shaft the inner is installed with guide wheel, and the guide wheel shaft in the guide wheel outside is provided with spring, spring extruding guide wheel, guide wheel contact guide rail, be provided with in the wheel frame outside and protect frame, protect frame and be connected with link, link by bolt on bearing support.Because the guide wheel of wheel frame contacts for the elasticity extrusion rolling with guide rail, so leave certain activity space, even verticality occurs under the situation of deviation when guide rail is installed, or certain reason causes the inclination of guide wheel group, the jam phenomenon can be do not occurred yet, thereby damage or destruction can be prevented effectively guide rail or guide wheel group.

The structure of described anti-drop device is: an end of two screw rods connects swivel nut separately, and the end of two swivel nuts is individually fixed on bearing support and the main frame by screw, connects by adjustable bolt in the middle of two screw rods.By regulating adjustable bolt, can regulate the tightness of anti-drop device.Three high anti-drop devices of difference are one group, are provided with some groups by horizontal distribution.When falling fast, because the effect of anti-drop device, connected scaffold is withstood, thereby reaches the effect of falling of preventing.

The structure of described lifting appliance is: jacking equipment adopts the loop chain motor hoist, and rope chain upper end hangs on to be fixed on the bearing support, and the lower end is provided with suspension hook, and suspension hook is hung on the hook of horizontal tray.

The utlity model has following beneficial effect: prove that by engineering practice the utility model is not only safe, stable, simple to operate, efficiency of construction is high, and compare with other scaffold, less investment, cost are low, the comprehensive benefit height, comprehensive above-mentioned situation, advantage has: 1, economical with materials expense.The utility model height is about 14.4 meters (being generally 4～5 layer heights of building), promotes according to construction speed, in high-building construction, will save a large amount of steel pipes, fastener etc. than single scaffold, double-pole scaffold.2, save labour cost.After the utility model is set up, only need a small amount of personnel carry out the lifting of support body, saves a large amount of manually.3, save machinery expenses.After the utility model is set up, utilize the jacking system of self just can carry out lifting, than a large amount of tower crane machine-team time of boat scaffold saving.4, high efficiency.After the utility model was set up, the whole lifting time did not influence other work, saved the duration, reduced expenditure cost.
