Abstract
The utility model discloses a creeping formwork structure with the self-locking function. The creeping formwork structure with the self-locking function comprises a workbench, a formwork, a creeping rod and an anchor cone. The formwork is arranged on the upper working surface of the workbench. One end of the anchor cone is fixed in a concrete structure, and the other end of the anchor cone is matched with the creeping rod. A rack is arranged at the lower portion of the creeping rod and matched with a transmission gear. The transmission gear and a worm wheel rotate coaxially. The worm wheel is driven by a worm. The worm is driven by a motor. The lead angle of the worm is smaller than the equivalent frictional angle between meshed gear teeth so that the self-locking function of a worm wheel and worm structure can be ensured. The creeping formwork structure with the self-locking function has the advantages that the defects brought by a hydraulic transmission mode can be overcome, the creeping rod is driven by the worm wheel and worm structure to be lifted, and due to the self-locking function of the worm wheel and the worm, reliability is largely improved.
Description
Technical field
The utility model relates to building machinery field, is a kind of creeping formwork specifically.
Background technology
Existing creeping formwork structure generally adopts hydraulic-driven, as the Chinese Patent Application No. Patent Application Publication that is 200310108851X a kind of double-acting hydraulic climbing die block system, it is attached to surface of wall, comprise: template system, attached wall system, guidance system, anti-drop system, climbing scaffold system, synchronously climb monitoring system, hydraulic system, similar patent is many in addition; Their common feature is to adopt hydraulically powered mode to promote creeping formwork, at the scene in work progress, because the pipe joint of hydraulic system is more, once cause and in the process of climbing, joint occur or pipeline leakage can cause serious accident, in addition, hydraulic test is heavier, and transport is inconvenient, and cost is higher.For this reason, Chinese Patent Application No. 201110064786.X discloses a kind of electronic climb formwork platform; Include template body; climbing frame, guide rail, anti-fall anti-dumping supporting seat; wherein template body is arranged on climbing frame top; guide rail is vertically fixed on climbing frame; anti-fall anti-dumping supporting seat is arranged on building and with guide rail and matches; it is characterized in that: anti-fall anti-dumping supporting seat below is provided with electric block, and electric block is connected with the bottom of climbing frame by chain; Although this technology adopts electronic mode to drive creeping formwork, owing to adopting electric block structure, and its anti-fall anti-dumping employing rack structure, reliability is poor.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of electronic creeping formwork, can solve the defect that hydraulic transmission mode brings on the one hand, on the other hand, the utility model adopts worm gear structure to drive pole-climbing to promote, and utilizes the auto-lock function of worm and gear, and reliability improves.Concrete technical scheme is as follows:
With a creeping formwork structure for auto-lock function, comprise workbench, mould bases, pole-climbing, anchor cone, described mould bases is arranged on the upper work plane of workbench; Described anchor cone one end is fixed in concrete structure, and the other end coordinates with pole-climbing; The bottom of described pole-climbing arranges tooth bar, and described tooth bar coordinates with travelling gear; Described travelling gear and worm gear coaxial rotation, described worm gear is by worm drive, and described worm screw is driven by motor, and the lead angle of described worm screw is less than the equivalent friction angle of meshing wheel between cog to ensure the self-locking of worm gear structure.
For ensureing that the pressure that upper work plane bears is directly delivered to lower work plane, alleviate the anti-fall pressure that the structure of inclining is born of putting, described anchor cone also coordinates with the main support column that supports upper and lower work plane.
The utility model has the advantages that: can solve the defect that hydraulic transmission mode brings on the one hand, on the other hand, the utility model adopts worm gear structure to drive pole-climbing to promote, and utilizes the auto-lock function of worm and gear, and reliability improves.

Detailed description of the invention
Illustrate the utility model below in conjunction with accompanying drawing, as Figure 1-Figure 4, the utility model comprises workbench, mould bases 2, pole-climbing 8, anchor cone 3, and described mould bases 2 is arranged on the upper work plane of workbench; Described anchor cone 3 one end are fixed in concrete structure 1, and the other end coordinates with pole-climbing 8; The bottom of described pole-climbing 8 arranges tooth bar 95, and described tooth bar 95 coordinates with travelling gear 94; Described travelling gear 94 and worm gear 91 coaxial rotation, described worm gear 91 is driven by worm screw 92, and described worm screw 92 is driven by motor 94, and the lead angle of described worm screw 2 is less than the equivalent friction angle of meshing wheel between cog to ensure the self-locking of worm gear structure.
For ensureing that the pressure that upper work plane bears is directly delivered to lower work plane, alleviate the anti-fall pressure that the structure of inclining is born of putting, described anchor cone 3 also coordinates with the main support column 5 that supports upper and lower work plane.
Described workbench comprises work plane 7, lower work plane 8, main support column 5;
The described anti-fall structure of inclining of putting comprises two guide grooves 4 that are arranged between work plane 7 and lower work plane, the interior travelling gear 94 that pole-climbing 8 is set and coordinates with pole-climbing 8 bottom tooth bars of described guide groove 4, pole-climbing 8 tops coordinate to ensure that pole-climbing is stable, do not reverse with pole-climbing through hole and the guide groove 4 of upper work plane.
The drive units such as described motor are fixed on lower work plane 8.
When the utility model uses, can drive worm gear to rotate by motor, worm gear band nutating gear, travelling gear drive tooth bar to move upward, and then move in driving pole-climbing; Move on to permanent position in pole-climbing time, coordinate with pre-buried anchor cone, then motor reversal, drives work plane to be promoted to predetermined altitude, worm gear structure self-locking.
The structure that anchor cone of the present utility model coordinates with pole-climbing can adopt known technology, as all open in patents such as Chinese Patent Application No. 2004200763546.
