Description
Technical field
The present invention relates to a kind of tower crane hook, and in particular to a kind of new to avoid sliding tower crane hook structure.
Background technology
Tower crane is most common a kind of lifting equipment also known as " derrick crane " on construction site, is connect with a section
It is long, for hanging the raw material of the constructions such as working reinforcing bar, wood stupefied, concrete, steel pipe.Tower crane is a kind of essential on building site
Equipment.The function of tower crane point is subject to the upper load that arm support drawstring and counter-jib drawstring transmit, and by turning round pylon, turning
The structure member formula of platform, bearing etc. directly passes to tower body structure by turntable.There is truncated cone pillar from a liter tower top, lean forward or hypsokinesis
Truncated cone pillar, herringbone posture and diagonal brace posture.Every upper rotary tower crane is both needed to set balance weight, its function is supporting balance weight, is used
The trimming moment opposite with hoisting moment direction in terms of with effect required on Construction designing.In addition to balance weight, also Chang Qi
Afterbody installs lifting mechanism.Why homostasis weight is placed in counter-jib tail end to lifting mechanism together, first can play part and match somebody with somebody
Recast is used, and second increases the distance between rope reel and pinnacle of a pagoda guide wheel, with the row of sharp steel wire rope around and avoid that disorder cable phenomenon occurs.It is flat
The dosage of weight and the length of counter-jib inversely, and balance between arm lengths and jib length that there are certain proportion
Relation.Counterpoise is considerable, and light-duty tower crane generally at least wants 3~4t, and heavy wants nearly 30t.
But existing tower crane is in lifting, since suspension hook does not have protective device, it is possible that the rope of lifting is from hanging
Situation about being slid on hook.
The content of the invention
The technical problems to be solved by the invention are, and it is an object of the present invention to provide a kind of new for tower crane hook protection device for installing
Avoid sliding tower crane hook structure, solve existing tower crane in lifting, since suspension hook does not have protective device, it is possible that lifting
Rope the problem of being slid from suspension hook.
The present invention is achieved through the following technical solutions：
It is a kind of it is new avoid sliding tower crane hook structure, including suspension hook coupler body, the bottom on the inside of suspension hook coupler body are also provided with
Square groove, to be hung down naturally using suspension hook be upwardly positive direction of the y-axis with being perpendicular to, suspension hook opening direction is negative direction of the x-axis, recessed
Coordinate system is established in groove bottom center for origin, and the groove wall top of groove negative direction of the x-axis is provided with connecting shaft, is set in connecting shaft
There is the connecting rod parallel with x-axis, connecting shaft is located at the midpoint of connecting rod, and connecting rod passes through spring and groove negative direction of the x-axis cell wall
Bottom connection, be additionally provided with the endpoint of connecting rod negative direction of the x-axis to first quartile extend grab.Pass through above-mentioned knot
Structure, for suspension hook when fishing takes rope, rope is since gravity slides to suspension hook bottom, and connecting rod is around connecting shaft under the action of rope
Rotate clockwise, the grab in connecting rod is acted with connecting rod around connecting shaft, and rope is locked by connecting rod, grab, groove-bottom
In face and the space of groove positive direction of the x-axis cell wall, after the completion of lifting, connecting rod resets under the action of the spring.
For the grab with connecting rod into 60 degree of angles, grab length is 0.85 times of connection pole length.Using above-mentioned data
Grab can preferably be coordinated with groove positive direction of the x-axis cell wall, and rope is locked.
One end of the connecting rod positive direction of the x-axis is additionally provided with the fastener of protrusion.Said structure is taken to avoid hoisting process
Middle rope skids with connecting rod causes connecting rod to be upspring.
Connecting shaft uses ball bearing.Ball bearing is one kind of rolling bearing, and spherical alloy steel ball is installed on interior steel
The centre of circle and outer rim, is imitated with roll mode to reduce the frictional force in power transmission process and improve the transmission of machine power
Rate.Ball bearing cannot bear larger heavy load, due to connecting shaft not load-bearing, so can in light indusqtry machinery more typically
To use ball bearing.
Compared with prior art, the present invention have the following advantages and advantages：
1st, the present invention it is a kind of it is new avoid sliding tower crane hook structure, it is safe；
2nd, the present invention it is a kind of it is new avoid sliding tower crane hook structure, the transformation of existing suspension hook can be passed through and obtained, improving cost
It is low.
