Description

Attached lift scaffold

Technical field

The utility model relates to the improvement technology of high-building construction with attached lift scaffold, is specifically related to a kind of force-bearing situation that improves anti-drop device and anti-tilt device, realizes even running, effectively fixing and anti-fall attached lift scaffold.

Background technology

Flourish along with domestic construction market also arises at the historic moment as the various scaffolds of construction equipment.Wherein attached lift scaffold with its save material, safe and practical and particularly vast unit in charge of construction favored.Attached lift scaffold mainly comprises three parts such as frame structure, jacking system and electrical apparatus control system.Described frame structure is made up of vertical main frame, horizontal beam frame and framework; Described adhering lifting system is made up of attached support structure, elevating mechanism and safety guard.Most importantly vertical main frame in the frame structure, its inboard is provided with guide rail and anti-fall tooth.Guide rail matches with leading anti leaning equipment, plays guiding and anti-dumping effect; Under the work operating mode, generally be to withstand the anti-fall tooth on the vertical main frame and frame structure is fixed on the building by falling proof device.Device such as leading anti leaning equipment, falling proof device 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 realized lifting by jacking equipment.

The disclosed ZL00222196.9 of Chinese patent " attachment type raise scaffold ", can realize the anti-fall of lifting process easily, but anti-fall push rod adopts the circle screw rod, its threaded portion effect is to regulate push rod length, push rod head chamfering is bigger, so that push rod puts in anti-fall tooth root portion, withstand anti-fall tooth.But because anti-fall tooth is a steel plate, and push rod is a round bar, so its contact is a contact, cause local stress excessive easily, next is not enough owing to contact area owing to this some contact causes between push rod and the anti-fall tooth easily, causes the easy slippage of push rod, the situation that push rod withstands on anti-fall tooth bracketed part often occurs, cause anti-fall tooth to be subjected to the moment of flexure effect and be out of shape even destroy, influence is normally used.Simultaneously, leading anti leaning equipment adopts round steel to bend the guide grab that forms, insert the interior anti-dumping guide effect of gathering sill of guide rail, be sliding friction between guide grab and the guide rail like this, verticality occurs under the situation of deviation when guide rail is installed, often make the bigger jam power of formation, guide rail or guide grab are caused moderate finite deformation damage or destruction.

The utility model content

At the prior art above shortcomings, the purpose of this utility model provides the attached lift scaffold that a kind of running resistance is little, anti-drop device is safe and reliable.

The technical scheme that its technical problem that solves the utility model adopts is such: a kind of attached lift scaffold comprises and adheres to supporting arrangement that jacking equipment and frame structure, frame structure comprise horizontal beam frame, vertical main frame and support body framework; Horizontal beam frame is connected with vertical main frame bottom; The support body framework is connected with vertical main frame with horizontal beam frame respectively; Frame structure by vertical main frame with adhere to supporting arrangement and be connected; Adhering to supporting arrangement is connected on the building by through-wall bolt, adhere to supporting arrangement and be provided with leading anti leaning equipment and falling proof device, the anti-fall tooth that vertical main frame is provided with guide rail and is provided with according to a determining deviation, leading anti leaning equipment is connected with the guide rail sliding sleeve, and scaffold play the guiding role when playing operation; Falling proof device is detachable the connection with anti-fall tooth on the main frame, and when scaffold fell fixedly the time or in the running, falling proof device withstood anti-fall tooth, plays anti-fall effect; When scaffold moved, falling proof device and anti-fall tooth broke away from, and make the scaffold trouble-free operation, and it is characterized in that: leading anti leaning equipment and guide rail are rolling friction; When anti-drop device withstood anti-fall tooth, its contact position was an anti-fall tooth root portion, and the way of contact is the face contact.

Compared to existing technology, the utlity model has following useful technique effect: increased the contact area between anti-drop device and the anti-fall tooth, reduced the pressure that is subjected on the unit area, in addition, anti-fall push rod changes rectangle into from circle, can withstand on anti-fall tooth root portion when making anti-drop device stressed, thereby has improved the force-bearing situation of anti-fall tooth, change the friction mode between leading anti leaning equipment and the guide rail simultaneously, the jam power when reducing to move.Even running, effectively fixing and anti-fall effect have been realized.

Below in conjunction with the description of drawings and the specific embodiment the utility model is further described.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, a kind of attached lift scaffold of the utility model comprises leading anti leaning equipment 4, falling proof device 5, adheres to supporting 3, jacking equipment 6 and frame structure.Leading anti leaning equipment 4 and falling proof device 5 are installed in and adhere in the supporting 3, describedly adhere to supporting 3 and be installed on the building 8 by through-wall bolt 7, its effect is to comprise that with adhering to supporting 3 load of being born support body deadweight and the working load that acts on the support body effectively pass to building 8.Frame structure comprises horizontal beam frame 1, vertical main frame 2 and support body framework.The support body framework adopts building operations scaffolding steel pipe and fastener commonly used to set up, and its vertical rod is bearing on the horizontal beam frame 1, and its inside and outside horizon bar forms the structure of mass action respectively by being connected with vertical main frame 2 respectively with fastener; Horizontal beam frame 1 adopts U-bolt 11 to be connected with vertical main frame 1 bottom; Guide rail 21 on the vertical main frame inboard is installed in the leading anti leaning equipment 4; Guide rail 21 is two round steel pipe that are parallel to each other and keep at a certain distance away, and is provided with the anti-fall tooth 22 that many groups are welded by steel plate according to a determining deviation between the round steel pipe.Vertical main frame 7 is connected with attached support structure 1.Anti-tilt device 4 is such with the annexation of guide rail 2, as shown in Figure 3: be fixed by bolts at anti-dumping pivot pin 41 and adhere in the supporting 3, anti-dumping pivot pin 41 overhead cover axle sleeves 42, axle sleeve 42 can rotate along anti-dumping pivot pin 41 centres of gyration.The front, rear, left and right of guide rail 2 are equipped with on four anti-tilt devices with structure altogether, and when scaffold moved, guide rail 22 rose or descends with scaffold, when contacting with anti-tilt device 4, axle sleeve 42 withstands on guide rail 22 peripheries, and rotates, thereby has reduced the operating resistance of scaffold greatly.Scaffold is operated steadily, avoided common jam phenomenon.

Falling proof device 5 comprises tongue 51 and body 52, tongue 51 sliding sleeves are installed in the body 52, its top is protruding, tongue 51 cross sections are rectangle, falling proof device 5 withstood anti-fall tooth 22 when its anti-fall effect was achieved in that work, the bottom of tongue 51 withstands on to be regulated on the bolt 53, regulating bolt 53 other ends stretches out outside the body 52, match with the nut that is welded on body bottom 52, rotate and regulate bolt 53 heads, just can regulate the length that tongue 51 stretches out body 52, thereby make the many groups falling proof device 5 that is installed on the same facade can withstand anti-fall tooth 22 simultaneously, guarantee safety.
