Abstract
The invention discloses a multifunctional crane hook. The multifunctional crane hook is characterized by comprising a connecting rod; a rectangular through hole is formed in the connecting rod in the axial direction; a hook body is arranged on the outer round face at the bottom of the connecting rod; a push rod is arranged in the rectangular through hole of the connecting rod; the bottom end of the push rod stretches out of the connecting rod and is connected with a barb-shaped check block; a rack is arranged on the side face of the push rod; one side of the connecting rod is provided with a through groove communicating 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 rack of the push rod; a supporting shaft of the worm is slidably arranged in the grooves in the two sides of the through groove; a spring is arranged between the supporting shaft of the worm and the side faces of the grooves; a gravity sensor is arranged on the hook body; an alarm and a controller are arranged on the connecting rod; the gravity sensor is connected with the controller; and the controller is electrically connected with the alarm. The multifunctional 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 multifunctional crane suspension 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 traditional multifunctional crane suspension hook
It is in opening-wide state, heavier or have under certain wind state in workpiece, because multifunctional crane suspension hook bottom is smooth, lifting
Suspension hook is easily caused workpiece and slips, and in turn results in certain danger.
Content of the invention
It is an object of the invention to provide a kind of multifunctional crane suspension 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 multifunctional crane suspension 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, is provided with worm screw in groove, worm screw is meshed with the bar tooth of push rod；Described suspension hook is provided with gravity
Sensor；Described connecting rod is provided with alarm and controller；Described gravity sensor is connected with controller, controller and warning
Device electrically connects.
The invention has the beneficial effects as follows,
By pulling out worm screw, because worm screw makes barb-shaped block quickly move to suspension hook with the cooperation of bar tooth, so that barb
The bottom of shape block is in close contact with suspension hook；Restart crane movable workpiece, the bar tooth due to worm screw and push rod coordinates, it is to avoid
Other active forces make push rod drive barb-shaped block to move up, and the danger of workpiece landing 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.
Brief description
Fig. 1 is the structural representation of Suspension hook structure；
Fig. 2 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 multifunctional crane suspension hook that the shown present invention of Fig. 1-2 provides, includes suspension hook 1, barb-shaped block 2, connection
Bar 3, worm screw 4, rectangular through-hole, bar tooth 6 and push rod 7.This multifunctional crane suspension 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；In the rectangular through-hole of described connecting rod 3
The push rod 7 being provided with；Connecting rod 3 is stretched out in the bottom of described push rod 7, and is connected with barb-shaped block 2；The side of described push rod 7 sets
There is bar tooth 6；The side of described connecting rod 3 is provided with the groove 8 communicating with rectangular through-hole, is provided with worm screw 4 in groove 8, worm screw 4 with
The bar tooth of push rod 7 is meshed；The top of described push rod 7 passes through the top of connecting rod 3；Described suspension hook 1 is provided with gravity sensor；
Described connecting rod 3 is provided with alarm and controller；Described gravity sensor is connected with controller, and controller is electrically connected with alarm
Connect.
Operation principle：By pulling out worm screw 4, because worm screw 4 and bar tooth 6 cooperation make barb-shaped block 2 quick to hanging
Hook 1 is mobile, thus the bottom of barb-shaped block 2 is in close contact with suspension hook 1；Restart crane movable workpiece, due to worm screw 4 with
The bar tooth 6 of push rod 8 coordinates, it is to avoid other active forces make push rod 7 drive barb-shaped block 2 to move up, and workpiece landing and hang
The danger of 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
Change, equivalent, improvement etc., should be included within the scope of the present invention.
