Abstract

The utility model relates to a rail-lifting scaffold for construction works, which comprises a rail, an external frame, a plurality of bearing guide pulley sets, a gourd, a lifting seat, a frame connecting rod, an adjustable wall connecting rod, and a structure for supporting and fixing the rail and the external frame. The utility model is characterized in that each of the guide pulley sets are arranged into a vertical line which is parallel with a wall surface; the rail is arranged on a railway line which is constrained by the guide pulley sets and can slide up and down along the railway line; the external frame is installed in parallel and connected into an integral body with the rail through the frame connecting rod. The rail-lifting scaffold for construction works eliminates the assembling and disassembling procedure of a guide way. The utility model not only reduces the erecting cost and the labor intensity of the external frame, but also makes construction safer, more convenient, and more efficient.

Description

The track hoisting scaffold

The utility model relates to the exterior wall scaffold of construction work.

The outrigger tradition of construction work is set up to completely taking along building height, needs to drop into lot of materials and artificial, the cost height, and work efficiency is low.Gradually reinstate hoisting frame at present and replace shelfful, guide tracked as a kind of DP--00 type from climbing scaffold, by outrigger, be fixed in guide wheel on the outrigger, connect and be fixed in guide rail in the building structure, promote hanging seat and pulley is formed by wall connecting rod.During use, outrigger and guide wheel along lifting rail, after putting in place, are locked on the guide rail with the supporting outrigger being contained in spacing lock on the outrigger under the effect of electric block, provide construction required bearing capacity.Because its guide rail is fixed on the building, guide rail can not be with the outrigger lifting, for reducing cost, adopt five joint guide rail turnovers to use, every joint rail length equals building typical floor floor height, connects with bolt between last lower guideway, will produce a guide rail dismounting operation in the use.The dismounting of high aerial heavy guide rail has brought unsafe factor, especially after outrigger climbs one deck, when dismantling below it one deck, or outrigger is each descend before, when one deck guide rail was installed below it, the workman was in the floor marginal operation.And when building is shear wall structure, also need under climbing frame, to increase the dismounting that a suspension bracket satisfies guide rail, and not only increased labour intensity, also buried potential safety hazard.Simultaneously because its rail length is pressed the design of typical floor floor height, thereby be not suitable for the floor floor height and change the more building and the building of two different floor heights, versatility is poor, and for the engineering of different floor heights, used guide rail needs preparation again, has increased cost.

The purpose of this utility model is: a kind of novel track hoisting scaffold is provided, lifting very easily, remove the dismounting operation of guide rail from, both reduce outrigger and set up cost and labour intensity, make building operations safer, more convenient and more efficient again, simultaneously, the utility model also has the advantage of highly versatile.

The technical solution of the utility model is: a kind of track hoisting scaffold comprises track, outrigger, some load guide wheel group, cucurbit and upgrade block; The top of described cucurbit is hung on the suspension ring that link to each other with described guide wheel group, and its lower end suspension hook is pulled on the described upgrade block; Described upgrade block is fixed in the lower end of described track, it is characterized in that: described track hoisting scaffold also comprises side link, adjustable wall connecting rod and with described track and external frame rest and fixing structure; Described load guide wheel group links by adjustable wall connecting rod and bolt and skin or beam, and each guide wheel group is arranged in a vertical straight line parallel with metope; Described track is positioned on the railway line that described guide wheel group retrains and can slides up and down along it; Described outrigger is connected with described parallel track installation and by described side link and forms a common integral body.

Aforesaid track hoisting scaffold, outrigger is connected as a whole with track, can slide up and down along the railway line that guide wheel group retrained very easily, removed the dismounting operation of guide rail from, both reduced outrigger and set up cost and labour intensity, and made building operations safer, more convenient and more efficient again.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the cell floor plan of an exemplary embodiments of the utility model;

Fig. 2 cuts open elevation for A--A among Fig. 1;

Fig. 3 is the enlarged drawing of the node that guide wheel group is connected with exterior wall among Fig. 2;

As Fig. 1--the track hoisting scaffold shown in 3 comprises track 1, outrigger 2, some load guide wheel group 4, cucurbit 7 and upgrade block 8; The top of described cucurbit 7 is hung on the suspension ring 11 that link to each other with described guide wheel group 4, and its lower end suspension hook is pulled on the described upgrade block 8; Described upgrade block 8 is fixed in the lower end of described track 1; Described track hoisting scaffold also comprises side link 3, adjustable wall connecting rod 6 and with described track and external frame rest and fixing structure; Described load guide wheel group 4 links with skin or beam by adjustable wall connecting rod 6 and bolt 9, and each guide wheel group is arranged in a vertical straight line parallel with metope; Described track 1 is positioned on the railway line that described guide wheel group 4 retrained and can slides up and down along it; Described outrigger 2 is connected to a common integral body with described track 1 parallel installation and by described side link 3.

As shown in Figure 3, described track and external frame rest and fixing structure are comprised the base plate 14 that the top with described guide wheel group 4 is fastenedly connected, on this base plate 14 with described track 1 on the force-bearing pin 12 that is processed with corresponding load pin-and-hole 15 and matches with the load pin-and-hole.

For the purpose of improving structural strength, can in the structure of this scaffold, increase adjustable drawbar 5, described adjustable drawbar 5 one ends connect with the link plate of adjustable wall connecting rod 6 by the wall place, and the other end and a following adjacent load guide wheel group 4 link; Described adjustable drawbar 5 is made up of the swivel nut 10 of two sections pull bar and connection top and the bottom, and its connecting mode is a thread connection.Twisting swivel nut 10 is the length of compensation linkage 5.The structure of adjustable wall connecting rod 6 similarly, different is that its connection part will have enough flexural strengths.Referring to Fig. 2 and Fig. 3.

For further improving the safety of scaffold, safety stop lever 13 of design on the limit of described track 1 can leaned on the described guide wheel group 4, one end of this pin 13 is hinged on the described guide wheel group 4, the other end is a free end, this free end can upwards rotate, but it is subjected to guide wheel group 4 constraints and can not rotates; Side by described pin 13 on described track 1 is provided with some positive stops, two bolt of mounting method for being connected with track 1 by side link 3.Referring to Fig. 3.

Use of the present utility model is as follows: start cucurbit 7, after track 1 rises together with outrigger 2 or drops to preposition, force-bearing pin is inserted in the pin-and-hole 15 corresponding mutually on described base plate and the track 1, and fastening with nut, provide bearing capacity by force-bearing pin to outrigger 2 and working load.If in lifting process, occur unexpected (malfunctioning) as cucurbit 7, the situation of outrigger 2 together with track 1 tenesmus takes place, safety pole 13 will stop the limited block on the track 1, and makes track 1 stop tenesmus together with outrigger 2, guarantees safe construction.
