Description
Technical field
The utility model relates to a kind of cranes, fast more particularly, to a kind of tower type crane boom root section and tower crane pin shaft
Mounting mechanism.
Background technique
Derrick crane is also known as tower crane, it is mainly used in housing construction, be suitble to the material in construction into
The horizontal and vertical conveying of row, can be used for the installation to building element, be the common transporting equipment in construction, and tower
The general height of heavy-duty machine is tens meters to several hundred rice.Boom is the important building block of derrick crane, since length is big, in order to
It is readily transported, by several Duan Zucheng, is assembled in working site, then in vertical tower, with tower crane upper bracket or tripod or tower
First-class component connects in the air.The cantilever crane root section of derrick crane connect general straight with tower crane tripod or upper bracket or tower head at present
Connect using pin shaft connect, be directly connected to form as shown in Figure 1 for existing pin shaft: i.e. using pin shaft 652 to be welded on tripod or
Otic placode 62 on upper bracket 61 is directly connected to the pin shaft otic placode 64 being welded on boom root section 63.Using this direct with pin shaft
The mode of connection has the disadvantage in that
1, high to upper bracket or tripod otic placode connecting hole concentricity machining needs；
2, high to cantilever crane root section pin shaft otic placode connecting hole concentricity requirement, while needing strict control welding deformation amount；
3, when high-altitude connects, it is desirable that connecting hole centering simultaneously in two sides is difficult；
4, sledgehammer is needed to strike pin shaft, large labor intensity, risk height when live high-altitude installation.
Summary of the invention
The purpose of the utility model is to provide a kind of tower type crane boom root sections and tower crane pin shaft quick assembling mechanism.The fast-assembling
Mechanism can reduce tower crane installment work intensity, reduce the set-up time, reduce peace and split into this.
Of the existing technology in order to solve the problems, such as, the utility model uses following technical scheme:
A kind of tower type crane boom root section and tower crane pin shaft quick assembling mechanism, including otic placode, fast-assembling connection frame and pin shaft ear
Plate, the otic placode are welded on the tripod, upper bracket or tower head of tower crane；The pin shaft otic placode is welded on boom root section；Ear
It is connected between plate and pin shaft otic placode by fast-assembling connection frame；The fast-assembling connection frame includes connection frame body, connection pin shaft, peace
Full pin shaft, spacer, axle sleeve, oscillating bearing and hand handle pin shaft, connection pin shaft are mounted on one end of connection frame body by pin shaft hole,
Spacer, axle sleeve and oscillating bearing are provided on connection pin shaft, and safe pin shaft and hand handle pin shaft are mounted on connection frame by pin shaft hole
The other end of body；Connection pin shaft is connect with otic placode, and safe pin shaft is connected with pin shaft otic placode.
The otic placode is borehole structure, and the pin shaft otic placode is semicircle pore structure.
The safe pin shaft and hand handle pin shaft are setting up and down.
The pin shaft hole for connecting with hand handle pin shaft being arranged on the connection frame body is long hole.
The safe pin shaft is positioning pin.
Due to the adoption of the above technical scheme, so that the utility model has the advantages that
The utility model due to use oscillating bearing, solve structural member bi-lug plate processing connecting hole concentricity it is poor, and
The problem of deformation generated in welding and transportational process.
Since pin shaft otic placode is to facilitate connection using half pore structure, reduces high-altitude installation strength, improves high-altitude installation
Safety.
Due to using hand handle pin shaft pre-assembled, facilitate this large-sized structural parts space lifting of cantilever crane in place, installing mechanism connects
Connecing hand handle pin shaft hole on frame body is long hole, wears pin shaft and is very easy to conveniently.
Since safe pin shaft uses positioning pin, it effectively prevent cantilever crane root section and tripod or upper bracket or tower head to be detached from, protects
The security reliability for demonstrate,proving connection, prevents the generation of failure.
It, can be with using the quick-connect machanism of the utility model when arm frame of tower crane and tripod, upper bracket or tower head are installed
Simplify the processing of tower crane structural member, installation and maintenance, reduce high altitude operation time and difficulty, reduces production cost, improve safety
Property.
