Description
Technical field
The present invention relates to crane technical field, in particular to a kind of crane hook assembly.
Background technology
Crane refers to many actions hoisting machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, along with China
Economic development, the range of application of crane and the field of use are more and more extensive.
Crampon, is the vitals of a kind of crane, is used for hooking up workpiece；But traditional crane hook is in spacious
Open state, heavier at workpiece or have under certain wind state, due to smooth bottom crane hook, crampon is easily caused
Workpiece slips, and in turn results in certain danger.
Summary of the invention
It is an object of the invention to provide a kind of crane hook assembly, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is:
A kind of crane hook assembly, it is characterised in that: include connecting rod；Described connecting rod offer through hole vertically；Institute
State the periphery bottom connecting rod and be provided with suspension hook；Being provided with the push rod running through through hole in described connecting rod, the bottom of push rod connects to be had
Barb-shaped block；Described push rod periphery is provided with helical tooth；The gear matched with helical tooth it is provided with in the middle part of described connecting rod；Institute
State suspension hook and be provided with gravity sensor；Described connecting rod is provided with alarm and controller；Described gravity sensor and controller
Connecting, controller electrically connects with alarm.
Further, the through-hole wall on described connecting rod top is provided with a tapered enlarging expanded outwardly；Described connecting rod
Top is provided with locking cap, and the outer surface on connecting rod top is connected by threaded engagement with locking cap inner surface；Described push rod stretches out
Connecting rod；Described push rod is arranged with snap ring at tapered enlarging.By tightening locking cap, owing to snap ring is positioned at tapered enlarging,
So that snap ring compresses push rod, it is prevented effectively from barb-shaped block and moves up and down after fixation.
Further, described snap ring is annular snap ring, and annular snap ring is provided with opening.
Further, described push rod is slidably matched with connecting rod.
Further, the periphery in the middle part of described connecting rod offers the arc groove communicated with through hole；Described gear can turn
Move and be arranged in circular arc, and be connected with helical tooth.
Further, described connecting rod is welded with suspension hook.
The invention has the beneficial effects as follows,
By swing pinion, owing to gear coordinates with the helical tooth of push rod, making push rod move up and down, push rod drives barb-shaped block
Quickly move to suspension hook, when the bottom of barb-shaped block touches suspension hook, thus complete suspension hook and close；Avoid traditional lifting
Machine suspension hook is in opening-wide state, heavier at workpiece or have under certain wind state, due to smooth bottom crane hook, and lifting
Suspension hook is easily caused workpiece and slips, and in turn results in certain danger.
After detecting, by gravity sensor, the preset value that the workpiece of suspension hook reaches gravity sensor, gravity sensor will
Sending a signal to controller, controller processes signal, and closes alarm circuit, and alarm starts to report to the police, thus points out operation
This workpiece of workman is overweight；It is effectively improved the service life of crane and avoids the occurrence of potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the structural representation of Suspension hook structure；
Fig. 2 is the connection diagram of gravity sensor, controller and alarm.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
The crane hook assembly that the present invention that Fig. 1-2 is shown provides, including suspension hook 31, barb-shaped block 32, connects
Bar 33, gear 34, push rod 35, snap ring 36, helical tooth 37 and locking cap 38.This crane hook assembly, including connecting rod 33；Institute
That states connecting rod 33 offers through hole vertically；Periphery bottom described connecting rod 33 is provided with suspension hook 31；Described connecting rod 33
Inside being provided with the push rod 35 running through through hole, the bottom of push rod 35 connects barb-shaped block 32；Described push rod 35 periphery is provided with spiral shell
Rotation tooth 37；The gear 34 matched with helical tooth 37 it is provided with in the middle part of described connecting rod 33；Described suspension hook 31 is provided with gravity sensitive
Device；Described connecting rod 33 is provided with alarm and controller；Described gravity sensor is connected with controller, controller and alarm
Electrical connection.
The through-hole wall on the top of connecting rod 33 is provided with a tapered enlarging expanded outwardly；The top of described connecting rod 33 sets
Locking cap 38, the outer surface on the top of connecting rod 33 is had to be connected by threaded engagement with locking cap 38 inner surface；Described push rod 35
Stretch out connecting rod 33；Described push rod 35 is arranged with snap ring 36 at tapered enlarging.By tightening locking cap 38, due to snap ring 36
At tapered enlarging, so that snap ring 36 compresses push rod 35, it is prevented effectively from barb-shaped block 32 and moves up and down after fixation.
Snap ring 36 is annular snap ring, and annular snap ring is provided with opening；Described push rod 35 is slidably matched with connecting rod 33；
Periphery in the middle part of described connecting rod 33 offers the arc groove communicated with through hole；Described gear 34 may be rotatably mounted at circular arc
In, and be connected with helical tooth 37；Described connecting rod 33 is welded with suspension hook 31.
Operation principle: by swing pinion 34, owing to gear 34 coordinates with the helical tooth 37 of push rod 35, make push rod about 35
Mobile, push rod 35 drives barb-shaped block 32 quickly to move to suspension hook 31, when the bottom of barb-shaped block 32 touches suspension hook 31
Time, thus complete suspension hook and close；Finally tighten locking cap 38, make snap ring 36 gripping push rods 35, it is to avoid push rod 35 is moved, and has
Effect avoids, owing to barb block 32 is upwards backed down by the active force of workpiece, the shortcoming that workpiece slips occur.
After detecting, by gravity sensor, the preset value that the workpiece of suspension hook reaches gravity sensor, gravity sensor will
Sending a signal to controller, controller processes signal, and closes alarm circuit, and alarm starts to report to the police, thus points out operation
This workpiece of workman is overweight；It is effectively improved the service life of crane and avoids the occurrence of potential safety hazard.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
