Description
Technical field
The utility model is related to a kind of tower crane hook, and in particular to a kind of tower crane hook with auto-lock function.
Background technology
Tower crane is a kind of crane gear also known as " derrick crane " the most frequently used 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 are transmitted, 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, and its function is supporting balance weight, is used
With hoisting moment trimming moment in opposite 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 occurring disorder cable phenomenon.It is flat
The consumption of weight and the length of counter-jib inversely, and balance and there is certain proportion between arm lengths and jib length
Relation.Counterpoise is considerable, and light-duty tower crane typically at least wants 3~4t, and heavy wants nearly 30t.
But, existing tower crane is in lifting, because suspension hook does not have protection device, it is possible that the rope of lifting is from hanging
Situation about being slid on hook.
Utility model content
Technical problem to be solved in the utility model is for tower crane hook protection device for installing, it is therefore intended that provide a kind of band
The tower crane hook of auto-lock function, solves existing tower crane in lifting, because suspension hook does not have protection device, it is possible that lifting
The problem of rope slides from suspension hook.
The utility model is achieved through the following technical solutions：
A kind of tower crane hook with auto-lock function, including suspension hook coupler body, the bottom on the inside of suspension hook coupler body is also provided with square recessed
Groove, it is y-axis positive direction, suspension hook opening direction upwardly as x-axis negative direction, groove floor to be hung down naturally using suspension hook with being perpendicular to
Center is that origin sets up coordinate system, is provided with connecting shaft, connecting shaft and is provided with and x on the cell wall top of groove x-axis negative direction
The parallel connecting rod of axle, connecting shaft is located at the midpoint of connecting rod, the bottom that connecting rod passes through spring and groove x-axis negative direction cell wall
Connection, is additionally provided with the grab extended to first quartile on the end points of connecting rod x-axis negative direction.Pass through said structure, suspension hook
When fishing takes rope, rope slides to suspension hook bottom due to Action of Gravity Field, and connecting rod is clockwise around connecting shaft in the presence of rope
Rotate, the grab in connecting rod is acted with connecting rod around connecting shaft, by rope lock by connecting rod, grab, groove floor and
In the space of groove x-axis positive direction cell wall, after the completion of lifting, connecting rod resets under the action of the spring.
The grab is with connecting rod into 60 degree of angles, and grab length is 0.85 times of connection pole length.Using above-mentioned data
Grab can preferably be coordinated with groove x-axis positive direction cell wall, and rope is locked.
One end of the connecting rod x-axis positive direction is additionally provided with the fastener of projection.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 arranged on into interior steel
The centre of circle and outer rim, the frictional force in power transmission process is reduced with roll mode and the transmission effect of machine power is improved
Rate.Ball bearing can not bear larger heavy load, due to connecting shaft not load-bearing, so can in light indusqtry machinery more typically
To use ball bearing.
The utility model compared with prior art, has the following advantages and advantages：
1st, a kind of tower crane hook with auto-lock function of the utility model, safe；
2nd, a kind of tower crane hook with auto-lock function of the utility model, can be transformed by existing suspension hook and obtained, improving cost is low.
