Abstract
The utility model discloses a detachable ground anchor of a tower crane, which comprises a base, main limb angle steel, four rib plates and two mounting devices. The main limb angle steel is fixedly arranged on the base; the center of form of the main limb angle steel is coincident with that of the base; the two mounting devices are respectively arranged at the top ends of two sides of the main limb angle steel fixedly and extend out from the top end of the main limb angle steel upwards; the rib plates are fixedly connected with the main limb angle steel and the base and play a role in supporting the main limb angle steel; two of the four rib plates are respectively arranged on two wing plates of the main limb angle steel; and the setting positions of the rest two rib plates ensure that extended lines of longitudinal centerlines of the rest two rib plates pass through the center of form of the main limb angle steel. The base is provided with eight mounting holes, and the mounting holes are uniformly distributed along a circumference using the center of form of the base as a center of a circle. By using the ground anchor, the tower crane can be applicable to various construction places.
Description
Technical field
The utility model relates to a kind of tower crane lower margin, particularly a kind of detachable lower margin.
Background technique
Tower crane is widely used in the construction projects such as industrial premises, power station, bridge, civil building; Its mounting type is now mainly based on fixed, as shown in Figure 1, the concrete foundation of promptly making a special use with the tower machine fixedly lower margin 11(be called for short lower margin) be embedded in the basis 14, during use, as shown in Figure 2, the body of the tower 12 with tower crane is connected by erecting device 13 with lower margin 11.But along with the development of Building technology, a lot of construction project can't be made special concrete foundation so that the tower machine to be installed.Especially large-scale steel structure is built, and some project tower crane can only be installed on steel structure girder or the pillar; And most steel structure also do not allow welding.And the means of fixation that tower crane of the prior art was suitable for is and is fixed on the concrete embedded lower margin; And do not consider that tower crane will be installed on the steel structure, so when concrete embedded lower margin can't be used in the job site, tower crane then can't use.
The model utility content
The problem that is run into when tower crane being installed at prior art, the detachable lower margin that the utility model provides a kind of novel being used to that tower crane is installed, this detachable lower margin comprises: base, main limb angle steel, four gussets and two erecting devices.Main limb angle steel is fixedly installed on the base, and the centre of form of main limb angle steel overlaps with the centre of form of base; Two erecting devices are fixedly installed on the top on two limits of main limb angle steel respectively, and are protruded upward by the top of main limb angle steel; Gusset is fixedlyed connected with base with main limb angle steel, and main limb angle steel is played a supporting role; In four gussets two are separately positioned on two wing plates of main limb angle steel, two other the elongation line that the position should guarantee its vertical center line is set should be by the centre of form of main limb angle steel.Base is provided with 8 mounting holes, and mounting hole is the circumference uniform distribution in the center of circle along the centre of form with base.
Detachable lower margin in the utility model, can will be arranged on the steel structure by bolt, the installation and removal of tower crane have been made things convenient for, and, four positions that are provided with that position and 8 mounting holes are set of strengthening gusset on the main limb angle steel make lower margin each several part more reasonable stress, improve the installation stability of tower crane, prolonged the working life of lower margin.

Embodiment
As shown in Figure 3, the detachable lower margin 1 in the utility model comprises: base 2, main limb angle steel 3, gusset 4 and erecting device 5.Main limb angle steel 3 is fixedly installed on the base 2, and main limb angle steel 3 is the angle steel of certain specification, and its centre of form overlaps with the centre of form of base 2.Two erecting devices 5 are fixedly installed on the top on two limits of main limb angle steel 3 respectively, and are protruded upward by the top of main limb angle steel 3.Gusset 4 is fixedlyed connected with base 2 with main limb angle steel 3, and main limb angle steel 3 is played a supporting role.The quantity of gusset 4 is generally 4, from four direction, main limb angle steel 3 is played a supporting role, it should be noted that, in four gussets 4 two are separately positioned on two wing plates of main limb angle steel 3, two other the elongation line that the position should guarantee its vertical center line is set should be by the centre of form of main limb angle steel 3.Make the more reasonable stress of gusset 4 like this, firm more, stable to the support of main limb angle steel 3.As shown in Figure 4, also be provided with 8 mounting holes 6 on the base 2, mounting hole 6 is the circumference uniform distribution in the center of circle along the centre of form with base 2.
As shown in Figure 5, during use, at first, use bolt, detachable lower margin 1 is fixedly installed on the steel structure 7, by erecting device 5 stacker crane body 12 is connected with detachable lower margin 1 then by the mounting hole on the base 26.Because mounting hole 6 is to be provided with along the circumference uniform distribution that is the center of circle with the centre of form of base 2, so each is bolt strained evenly rationally.
Disclosed detachable lower margin in the utility model can either be arranged on the steel structure frame of building by bolt, also can equally be embedded in the concrete foundation with fixedly lower margin of the prior art.So this lower margin is applicable to various building site.Made things convenient for the layout of tower crane.And the main limb angle steel centre of form of this lower margin overlaps with the base centre of form, and the position that is provided with of four gussets has guaranteed that also each gusset is stressed evenly, and it is the circumference in the center of circle that the mounting hole that is used for being connected with steel structure that is provided with on the base is distributed on the base centre of form.Detachable lower margin and steel structure or other basic connection stability have further been guaranteed.In detachable lower margin with said structure characteristics and the prior art fixedly lower margin compare that it is highly low, so have than advantages of higher stability and rigidity.
