Description
Technical field
It the utility model is related to a kind of tower crane device, the standard knot unit of more particularly to a kind of tower crane.
Background technology
Tower crane is crane gear the most frequently used on a kind of construction site, and high composition is connect using a section assembly of standard knot
Its tower body, for the construction raw material such as the reinforcing bar of lifting construction, wood stupefied, concrete and steel pipe.
At present, the standard knot of the tower crane of in the market as shown in Figure 1, including support bar 21 and connecting rod 22 form it is rectangular
Body frame structure, the angle of standard knot 2 are provided with screw 4, when installing standard knot 2, upper strata standard knot 2 are hung into lower floor's standard knot 2
Top, the screw 4 on each angle are interconnected, and operating personnel are inserted in screw 4 using bearing pin and fix the adjacent standard of two sections
Section 2.
Although this kind of standard knot can respectively save and be overlapped mutually fixation, when installing standard knot, it is necessary to which operating personnel exist
It is upper at the standard knot lifted after carrying out safety measure, manually it is fixed；And standard knot hoisting process is unstable
Property, very big potential safety hazard is brought to operating personnel.
Utility model content
The purpose of this utility model is to provide a kind of standard knot unit of tower crane, is carried out without operating personnel close to standard knot
It is fixed, so as to ensure that the safety of operating personnel.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of standard knot of tower crane
Unit, including the vertical standard knot placed on the ground, the standard knot is in cuboid framework structure, is set at the top of the standard knot
There is screw, the standard knot bottom is fixed with motor, and the motor is provided with downward output shaft, pressure is fixed with the output shaft
Contracting elastic component, the one end of the compression elastic piece away from output shaft are fixed with the bolt coordinated with screw.
By using above-mentioned technical proposal, during assembling, upper strata standard knot is placed into lower floor's standard knot using boom hoisting
On, after the mutual pairing of screw of bolt and lower floor's standard knot on the standard knot of upper strata, start motor driven bolt and rotate, screw up into
To fix two adjacent sections standard knot in screw.And the compression elastic piece set between bolt and the output shaft of motor, give
The space that bolt moves along screw direction.During dismounting, start motor reversal, bolt exits from screw, you can separate upper strata mark
Quasi- section and lower floor's standard knot；This standard knot uses during installation and removal without being arrived on operating personnel at standard knot
Bolt fixed standard section, but motor driven bolt lock standardization section is utilized, the safety of operating personnel is not only ensure that, is also improved
The automaticity of tower crane installation, accelerate the speed of the installation and removal of tower crane.
Further, the standard knot top horizontal is provided with steel wire rope.
By using above-mentioned technical proposal, when standard knot is installed, operating personnel are generally required first on standard knot in connection
The part of convenient lifting, after good standard knot to be fixed, then it is upper remove part to standard knot top, it is cumbersome；Therefore each
Save standard knot top horizontal and one steel wire rope is set, need to only catch on steel wire rope when lifting by crane standard knot can complete to lift by crane, and fix
After standard knot, unclamping steel wire rope can continue to lift by crane next section standard knot；Without, to operation on standard knot, ensureing on operating personnel
The safety of operating personnel, and without the part of the convenient lifting of repeated disassembled and assembled, save the plenty of time.

By using above-mentioned technical proposal, when lifting standard knot is installed, boom hoisting be placed on two pieces of sandwich panels it
Between, to hang oneself dynamic standard knot when, loose steel wire rope stress is exceptionally straight, make originally the sandwich panel in vertical state to boom hoisting
Rotate, two pieces of sandwich panel lower ends are mutually supported and closed, and so as to pin boom hoisting, prevent boom hoisting from rocking on a steel cord, influence
Lifting safety.
Further, the standard knot bottom is equiped with fixed bin, and the motor is placed in fixed bin, the fixed bin
Bottom, which is provided with, supplies the perforate that shaft stretches out.
By using above-mentioned technical proposal, because mounted standard knot can be long-term use of in outdoor, therefore, in order to prevent
Motor is put into the fixed bin of standard knot bottom setting by rain erosion by motor.And in order to not influence the use of motor, solid
Determine cassette bottom portion and be provided with perforate, the output shaft of power supply machine passes through.
Further, the standard knot bottom is corresponding with screw is fixed with sleeve, the output shaft, compression elastic piece and spiral shell
Bolt is placed in sleeve.
By using above-mentioned technical proposal, due to the setting of compression elastic piece, when motor driven bolt rotates, bolt can be with
Shaken with compression elastic piece, influence the installation of standard knot；Therefore, one on output shaft, compression elastic piece and bolt coat
It individual sleeve, can not only protect bolt not to be etched, extend its usage time, bolt can also be prevented to rock, facilitate motor will
Bolt is screwed into screw.In addition, bolt is stabilized in sleeve, and sleeve is fixed on standard knot, and then consolidated upper strata mark
The connection of quasi- section and lower floor's standard knot.
Further, fixed block is fixed with the top of the standard knot, the screw is arranged in fixed block, the fixed block
Bottom is fixed with the nut coordinated with bolt.
By using above-mentioned technical proposal, a nut is placed in fixed block bottom, after bolt is screwed into nut, to bolt
When applying pulling force, fixed block can block nut, prevent bolt from departing from fixed block, so as to the company between further stability criteria section
Connect.
Further, some guide grooves to stretch out are provided with the top of the standard knot, some guide grooves are in outside
Open shape to set, the directive wheel that the standard knot bottom is provided with and guide groove coordinates.
By using above-mentioned technical proposal, when installing standard knot, in order that bolt and screw alignment, using guide groove and lead
Coordinate to wheel, standard knot is progressively alignd in lifting, so as to facilitate motor driven bolt to be screwed among screw.
Further, the surface of the guide groove and directive wheel is coated with identification layer.
By using above-mentioned technical proposal, because no operating personnel are guided on standard knot, lifting personnel are difficult to
Align standard knot；Therefore, applied on guide groove and directive wheel and be covered with identification layer, make the quick capturing position of lifting personnel, and by
Guide groove and directive wheel alignment standard knot.
In summary, the utility model has the advantages that：
1. by the bolt of motor driven, automatic rotating bolt is sealed into screw progress, realizes the automatic of standard knot
Change sealed installation, without, to installing manually on standard knot, ensure that the safety of operating personnel on operating personnel；
2. by guide groove and directive wheel, when lifting by crane installation, the placement of standard knot is oriented to, realizes the quick of standard knot
Alignment.
