Abstract
The invention discloses a tower crane hook which comprises a connection rod. A rectangular through hole is formed in the connection rod in the axial direction. A hook body is arranged on the outer circle face of the bottom of the connection rod. A push rod is arranged in the rectangular through hole of the connection rod. The bottom end of the push rod extends out of the connection rod and is connected with a check block in a barb shape. A tooth strip is arranged on the side face of the push rod. One side of the connection rod is provided with a through groove made communicated with the rectangular through hole. Grooves are formed in the two sides of the through groove. A worm is installed in the through groove and engaged with the tooth strip of the push rod. A supporting shaft of the worm is arranged in the grooves in the two sides of the through groove in a sliding mode. A spring is arranged between the supporting shaft of the worm and the side face of each groove. The tower crane hook has the advantages of being simple in structure, reliable in operation and low in cost.
Description
Technical field
The present invention relates to crane technical field, in particular to a kind of tower crane lift hook.
Background technology
Crane refers to many actions hoisting machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, with China
Economic continuous development, the range of application of crane and also more and more extensive using field.
Crampon, is a kind of vitals of crane, is used for hooking up workpiece；But at traditional tower crane lift hook
In opening-wide state, heavier or have under certain wind state in workpiece, because tower crane lift hook bottom is smooth, crampon
It is easily caused workpiece to slip, in turn result in certain danger.
Content of the invention
It is an object of the invention to provide a kind of tower crane lift hook, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is：
A kind of tower crane lift hook it is characterised in that：Including connecting rod；The rectangle that offers vertically of described connecting rod leads to
Hole；The periphery of described connecting rod bottom is provided with suspension hook；The push rod being provided with described connecting rod rectangular through-hole；The bottom of described push rod
Connecting rod is stretched out at end, and is connected with barb-shaped block；The side of described push rod is provided with bar tooth；The side of described connecting rod be provided with
The groove that rectangular through-hole communicates, groove both sides are provided with groove, are provided with worm screw in groove, and worm screw is nibbled with the bar tooth phase of push rod
Close, the support shaft of worm screw is slidably arranged in the groove of groove both sides, is provided with bullet between the support shaft of worm screw and the side of groove
Spring；Described suspension hook is provided with gravity sensor；Described connecting rod is provided with alarm and controller；Described gravity sensor and control
Device processed connects, and controller is electrically connected with alarm.
The invention has the beneficial effects as follows,
By pulling out worm screw, so that worm screw is separated with the bar tooth of push rod, then promote again push rod make barb-shaped block quickly to
Suspension hook moves, and when the bottom of barb-shaped block is close to suspension hook, unclamps worm screw, by spring reset, makes the bar of worm screw and push rod
Tooth coordinates again, then rotary worm, the bottom of the barb-shaped block of trace regulation and the spacing of suspension hook, thus the bottom of barb-shaped block
End is in close contact with suspension hook；Restart crane movable workpiece, due to the bar tooth cooperation of worm screw and push rod, it is to avoid other active forces
Make push rod drive barb-shaped block to move up, the danger of workpiece landing suspension hook occurs.
After the workpiece that gravity sensor detects suspension hook reaches the preset value of gravity sensor, gravity sensor will
Send a signal to controller, controller process signal, and close alarm circuit, alarm starts to report to the police, thus pointing out to operate
This workpiece of workman is overweight；It is effectively improved the service life of crane and avoid the occurrence of potential safety hazard.
Brief description
Fig. 1 is the structural representation of Suspension hook structure；
Fig. 2 is the structural representation of worm screw and connecting rod cooperation；
Fig. 3 is the connection diagram of gravity sensor, controller and alarm.
Specific embodiment
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
The tower crane lift hook that the shown present invention of Fig. 1-3 provides, including suspension hook 1, barb-shaped block 2, connecting rod
3rd, worm screw 4, rectangular through-hole, groove 5, bar tooth 6, push rod 7, groove 8 and spring 9.This tower crane lift hook, including connecting rod 3；
Described connecting rod 3 offer rectangular through-hole vertically；The periphery of described connecting rod 3 bottom is provided with suspension hook 1；Described connecting rod
The push rod 7 being provided with 3 rectangular through-hole；Connecting rod 3 is stretched out in the bottom of described push rod 7, and is connected with barb-shaped block 2；Described
The side of push rod 7 is provided with bar tooth 6；The side of described connecting rod 3 is provided with the groove 8 communicating with rectangular through-hole, and groove 8 both sides are provided with
Groove, is provided with worm screw 4 in groove 8, and worm screw 4 is meshed with the bar tooth of push rod 7, and the support shaft of worm screw 4 is slidably arranged in logical
In the groove 5 of groove 8 both sides, between the support shaft of worm screw 4 and groove 5 side, it is provided with spring 9；The top of described push rod 7 passes through even
The top of extension bar 3；Described suspension hook 1 is provided with gravity sensor；Described connecting rod 3 is provided with alarm and controller；Described heavy
Force snesor is connected with controller, and controller is electrically connected with alarm.
Operation principle：By pulling out worm screw 4, so that worm screw 4 is separated with the bar tooth 6 of push rod 7, then promote push rod 7 again
Make barb-shaped block 2 quick mobile to suspension hook 1, when the bottom of barb-shaped block 2 is close to suspension hook 1, unclamp worm screw 4, by bullet
Spring 9 resets, and so that worm screw 4 and the bar tooth 6 of push rod 7 is again coordinated, then rotary worm 4, the bottom of the barb-shaped block of trace regulation 2 with
The spacing of suspension hook 1, thus the bottom of barb-shaped block 2 is in close contact with suspension hook 1；Restart crane movable workpiece, due to snail
Bar 4 is coordinated with the bar tooth 6 of push rod 8, it is to avoid other active forces make push rod 7 drive barb-shaped block 2 to move up, and workpiece and slides
Fall the danger of suspension hook.
After the workpiece that gravity sensor detects suspension hook reaches the preset value of gravity sensor, gravity sensor will
Send a signal to controller, controller process signal, and close alarm circuit, alarm starts to report to the police, thus pointing out to operate
This workpiece of workman is overweight；It is effectively improved the service life of crane and avoid 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, made any repair
