Abstract
The utility model discloses a tower base component which comprises a standard knot, and fixing devices for fixing the standard knot on ground, and is characterized by further comprising mounting supports, wherein the mounting supports are welded at the bottoms of four main chord members of the standard knot respectively; the fixing devices are foundation bolts; and square plates are welded at hook ends of the foundation bolts. The component has the benefits that the standard knot is fixed on the ground by the foundation bolts; since the foundation bolts are simple in manufacturing technology and lower in cost, the cost of the tower base component is lowered; the foundation bolts are round; the square plates are welded at the hook ends of the foundation bolts, so that friction between the bolts and a foundation is effectively ensured; the bolts are not damaged; and the mounting supports are welded at the bottoms of the main chord members, so that the mounting of the foundation bolts is greatly facilitated.
Description
Technical field
The utility model relates to a kind of column foot assembly, belongs to hoisting crane and manufactures field.
Background technology
The tower machine, the abbreviation of tower crane, be a kind of weight-lifting equipment for building operation.In general, the tower machine can be divided into by the function of each several part: column foot, tower body, turn round, hoist, the part such as equilibrium arm, crane arm, crane carriage, tower top, driver's cab.Wherein, column foot is that the tower machine is installed essential on the ground foundation, and with reference to Fig. 1, it comprises: standard knot 101, and the basic pin tool 102 that standard knot 101 is fixed on the ground.The basic pin tool 102 now used, its complex manufacturing technology, and also cost of manufacture is higher, so, make the also corresponding raising of cost of tower machine.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of manufacture craft is relatively simple, the relatively low column foot assembly of cost.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of column foot assembly comprises: standard knot, and the anchor fitting that standard knot is fixed on the ground, it is characterized in that, and aforementioned anchor fitting is holding-down bolt.
Aforesaid column foot assembly, is characterized in that, also comprises: erection support, aforementioned erection support is welded on respectively the bottom of four main chords of standard knot.
Aforesaid column foot assembly, is characterized in that, 4 holding-down bolts are installed on each erection support.
Aforesaid column foot assembly, is characterized in that, aforementioned holding-down bolt is light foot bolt circularly.
Aforesaid column foot assembly, is characterized in that, aforementioned light is the crotch end side of the being welded with plate of foot bolt circularly.
Usefulness of the present utility model is: adopt holding-down bolt that standard knot is fixed on ground, because the holding-down bolt manufacture craft is simple, cost is relatively low, so reduced the cost of column foot assembly; Holding-down bolt is light foot bolt circularly, and at the crotch end side of being welded with plate, has effectively guaranteed bolt and basic friction force, is unlikely to make bolt to extract destruction; Bottom welding erection support at main chord, greatly facilitated the installation of holding-down bolt.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing column foot assembly;
Fig. 2 is the structural representation of a specific embodiment of column foot assembly of the present utility model.
The implication of Reference numeral in figure: 101-standard knot, 102-basis pin tool, 201-standard knot, 202-holding-down bolt, 203-erection support, 204-main chord, 205-side's plate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
With reference to Fig. 2, column foot assembly of the present utility model comprises: standard knot 201, and the anchor fitting that standard knot 201 is fixed on the ground, concrete, this anchor fitting is holding-down bolt 202.
In the utility model, adopt holding-down bolt that standard knot is fixed on ground, replaced the basic pin tool of original use standard knot is fixed on ground, because the holding-down bolt manufacture craft is simple, cost is relatively low, so adopt holding-down bolt to reduce the cost of column foot assembly.
As a kind of preferred scheme, column foot assembly of the present utility model also comprises: erection support 203.Erection support 203 amounts to 4, is welded on respectively the bottom of four main chords 204 of standard knot 201, for the installation of foot bolt 202 easily.
More preferably, 4 holding-down bolts 202 are installed on each erection support 203, for the fastness of guaranteeing that the column foot assembly is installed.
In the utility model, holding-down bolt 202 is preferably light foot bolt circularly.
More preferably, light is the crotch end side of the being welded with plate 205 of foot bolt circularly, light circularly the crotch end of foot bolt do a major part, for guaranteeing holding-down bolt and basic friction force, be unlikely to make holding-down bolt to extract destruction, guarantee the safety that the tower machine uses.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
Claims (3)
1. a column foot assembly comprises: standard knot, and the anchor fitting that standard knot is fixed on the ground, it is characterized in that, and above-mentioned anchor fitting is light foot bolt circularly, and the light crotch end side of the being welded with plate of foot bolt circularly.
2. column foot assembly according to claim 1, is characterized in that, also comprises: erection support, above-mentioned erection support is welded on respectively the bottom of four main chords of standard knot.
