Abstract
The utility model provides a construction elevator standard knot rack bar device, wherein a mounting hole on a rack bar is arranged into a threaded hole, and a rack bar connecting block is welded on a standard knot frame. When the rack bar is installed, the fixed bolt is threaded through the standard knot frame and the rack bar connecting block, and enters the mounting hole of the rack bar to screw and fix the bolt. The arrangement can satisfy the installation demands of rack bars with various mode numbers to the maximum, the installation quality is guaranteed, the space is saved, and the outer shape is more beautiful.
Description
Technical field
The utility model relates to building hoist standard knot field, refers more particularly to building hoist standard knot rack gear arrangement.
Background technology
Present domestic general-duty building hoist standard knot is connected with tooth bar, be fixed on the standard knot framework after all adopting high strength bolt to pass the mounting hole of tooth bar, its fixed form has two kinds: the one, and tapping on the standard knot framework directly is fixed on bolt on the standard knot framework; The 2nd, bolt is directly passed the standard knot framework, and then fix with nut.When adopting above dual mode, the mounting hole on the tooth bar is unthreaded hole, and the mounting hole on the standard knot is a tapped bore.When adopting little modulus tooth bar,, can't adopt socket bolt during installation because the tooth bar oad diminishes, but adopt the outer-hexagonal bolt, and therefore can cause bolt tail to expose, it is not attractive in appearance again promptly to have taken the space, when the lifting thing is overweight, also might the generation accident.
Summary of the invention
The purpose of this utility model is to provide a kind of mounting hole on the tooth bar is become the building hoist standard knot rack gear arrangement of tapped bore, the installation requirement when being connected with standard knot to satisfy little modulus tooth bar.
For achieving the above object, the technical solution of the utility model is:
Mounting hole on the tooth bar of building hoist standard knot rack gear arrangement is a tapped bore, and the tooth bar mounting hole on the standard knot framework is a unthreaded hole, and the tooth bar contiguous block is welded on the tooth bar mounting hole place of standard knot framework.When tooth bar is installed, bolt of rear end plate passed unthreaded hole and tooth bar contiguous block on the standard knot framework after, be connected with tapped bore on the tooth bar.
Good effect of the present utility model is:
After mounting hole on the tooth bar is set to tapped bore, and the tooth bar contiguous block is welded on the standard knot framework, so just make when standard knot adopts the tooth bar of different moduluses, can satisfy the installation requirement of various modulus tooth bars to the full extent, and installation quality and convenient the installation have been guaranteed, saved the space, made outward appearance more attractive in appearance.

Fig. 2, building hoist standard knot rack gear arrangement structural representation.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing 1～2:
In Fig. 2, the two ends of standard knot framework 2 are welded with tooth bar contiguous block 4 respectively, when tooth bar 1 is installed, bolt of rear end plate are passed standard knot framework 2 and tooth bar contiguous block 4, enter in the mounting hole of tooth bar 1, tighten bolt of rear end plate 3 tooth bar 1 is fastened on the standard knot framework 2.
Fig. 1 is for installing the constitution diagram after tooth bar 1 is finished.
Claims (1)
1, a kind of building hoist standard knot rack gear arrangement that constitutes by tooth bar (1), standard knot framework (2), bolt of rear end plate (3) and tooth bar contiguous block (4), it is characterized in that, mounting hole on the tooth bar (1) is a tapped bore, tooth bar on the standard knot framework (2) is installed as unthreaded hole, tooth bar contiguous block (4) is welded on the tooth bar mounting hole place of standard knot framework (2), after bolt of rear end plate during installation (3) passes unthreaded hole and tooth bar contiguous block (4) on the standard knot framework (2), be connected with tapped bore on the tooth bar (1).
