Description

Lifting support of the rail conduction from promotion discharging platform

Technical field

The utility model relates to a kind of ancillary equipment of building and its applications, pick up by oneself more particularly, to a kind of rail conduction Rise the lifting support of discharging platform.

Background technique

As the skyscraper of China's expanding economy, social progress, city is more and more, in Construction of High-rise, week Turn material it is upper and lower have bad luck often become engineering constraint progress bottleneck, the terminal that discharging platform is had bad luck as circulation material, Its property easy to use and safety are often the emphasis of each engineering safety management.Traditional fashioned iron overhanging unloading platform often leads to Field fabrication is crossed, the artificial displacement of tower crane cooperation, process is tedious, and security risk is big.For this purpose, how scientifically to improve discharging platform makes With efficiency and security performance, select that there is high technology content, easy to operate, safe and reliable novel discharging platform, e.g., by certainly The guide rail and lifting device of body can successively climb with structural floor or drop to the discharging platform of designated position, be met with this The demand in market.

Summary of the invention

The purpose of this utility model be for prior art shortcoming and provide a kind of structure it is simple, can be with structural floor It successively climbs or declines and promote discharging certainly in the rail conduction of suitable position from the track frame detent for promoting discharging platform for rail conduction The lifting support of platform.

The purpose of this utility model is realized by following measures: a kind of rail conduction promotes the lifting branch of discharging platform certainly Seat, which is characterized in that it includes wall-attached supporting seat frame, the cylindricality rail rods arranged side by side for rail conduction from promotion discharging platform track frame Two groups of roller groups of sliding and the ratchet mechanism for preventing track frame from falling；The wall-attached supporting seat, which is provided with, is fixed on building side Through-wall bolt on beam, the roller group are made of a pair of parallel idler wheel, space that two idler wheel wheel rims surround and rail rods Diameter matches, and two groups of roller groups are fixed on wall-attached supporting seat frame, the space spacing that the wheel rim of two groups of roller group idler wheels surrounds with The spacing of cylindricality rail rods arranged side by side matches, and the ratchet mechanism is made of ratchet, L-type pawl, the long pommel hinge of L-type pawl It connects and is connected on the horizontal gird of attached wall carrier base, the short handle end of L-type pawl is oblique, and ratchet is fixed on attached wall by shaft On the side wall of support saddle frame, the vertical plane C of the short handle end of L-type pawl and two groups of roller group idler wheel symmetrical centres is located at ratchet In the gear teeth scope of activities of two sides.

Compared with prior art, using the utility model proposes a kind of rail conduction from promoted discharging platform lifting Support, have the advantages that overcome traditional fashioned iron hang discharging platform by tower crane cooperation manually shift, use drawback, Especially in Construction of High-rise, the novel standardization torn open that is not necessarily to repeatedly pacify of one kind is provided and promotes discharging platform certainly, it can be with structure Floor, which successively climbs or declines, promotes the track frame detent of discharging platform in place certainly for rail conduction.With standardization, Intelligence high construction efficiency, has a safety feature, the features such as economic benefit is obvious, fundamentally solves discharging in building engineering construction Platform safety management problems.

Detailed description of the invention

Fig. 1 be the utility model proposes one embodiment structural schematic diagram.

Fig. 2 is two groups of roller group structure schematic diagrames of rail rods sliding of Fig. 1 A-A section for track frame.

Fig. 3 is the ratchet mechanism schematic diagram that Fig. 1 B-B section prevents track frame from falling.

Specific embodiment

The utility model will be further described with reference to the accompanying drawings and embodiments: it is practical new that Fig. 1 ~ Fig. 3 shows this One embodiment structural schematic diagram of type.In figure, a kind of rail conduction promotes the lifting support of discharging platform certainly, it includes: Wall-attached supporting seat frame (1), the two groups of rollings slid for rail conduction from the cylindricality rail rods (41) arranged side by side for promoting discharging platform track frame (4) Wheel group (2) and the ratchet mechanism for preventing track frame (4) from falling.The wall-attached supporting seat frame (1) is equipped with and is fixed on building side bar Through-wall bolt (3).The roller group is made of a pair of parallel idler wheel (21), the space and rail rods that two idler wheel wheel rims surround (41) diameter matches, and two groups of roller groups (2) are fixed on wall-attached supporting seat frame (1), the wheel of two groups of roller group (2) idler wheels (21) The space spacing that edge surrounds matches with the spacing of cylindricality rail rods (41) arranged side by side.When the utility model is used, track frame and Two groups of roller group idler wheels of colonnade shape rail rods and wall-attached supporting seat frame form prismatic pair, and track frame is surrounded in two groups of idler wheel wheel rims It is slid in space.The ratchet mechanism is made of ratchet (51), L-type pawl (52), and the long pommel of L-type pawl (52) hingedly connects It connects on the horizontal gird of attached wall carrier base (1), the short handle end of L-type pawl (52) is oblique, and ratchet (51) is solid by shaft It is scheduled on the side wall of wall-attached supporting seat frame (1), the short handle end of L-type pawl (52) and two groups of roller group (2) idler wheel (21) symmetrical centres Vertical plane C be located in the gear teeth scope of activities of ratchet (51) two sides.Two groups of roller group idler wheels in this structure are symmetrical Plane where the vertical plane, that is, track frame at center cylindricality rail rods arranged side by side, the fall arrest of track frame are marked time bar (42) and L-type The short handle end of pawl (52) is located at the two sides of ratchet, and when track frame is elevated under the effect of external force, track frame is prevented The bar of marking time of falling rises ratchet is driven to rotate counterclockwise, and the gear teeth of ratchet slide along the short handle inner surface of L-type pawl, enable L-type spine Pawl rotates clockwise, and L-type pawl, which concedes space, rises track frame smoothly.When track frame will fall, track frame Fall arrest is marked time bar downslide, and the short handle end of L-type pawl is influenced by itself weight, short handle end can be stuck in ratchet two gear teeth it Between, it blocks ratchet and is not able to rotate, track frame is prevented to drop, it is ensured that accidents happened for safety.

The embodiments of the present invention is described above in conjunction with embodiment, the structure that embodiment provides is not constituted to this The limitation of utility model, those skilled in the art in the art make various deformations or amendments within the scope of the appended claims In protection scope.
