Abstract
The invention relates to the technical field of a hoisting claw device and in particular relates to a hoisting claw device for a travelling crane. The hoisting claw device for the travelling crane comprises four claw hooks which are paired in a corresponding manner, wherein the top part, the middle part and the tail part of each claw hook are provided with pin holes, pins of which the middle parts are sheathed with fixing sleeves are arranged in four pin holes at the top parts of the four claw hooks correspondingly, two pins of which the middle parts are sheathed with fixing sleeves are arranged in two groups of pin holes in the middle parts of the four claw hooks correspondingly, two pins of which the middle parts are sheathed with fixing sleeves are arranged in the two groups of pin holes at the tail parts of the four claw hooks correspondingly, and claws for holding an article are arranged at the tail ends of the four claw hooks. According to the hoisting claw device for the travelling crane, the claws are arranged at the grabbing parts of the claw hooks, and therefore, the hoisting claw has a good locating effect, and the article cannot be separated from the hoisting claw easily.
Description
Technical field
The present invention relates to the technical field of hanging jaw arrangement, especially a kind of driving is with hanging jaw arrangement.
Background technology
Drive a vehicle substantially the same with the hoisting crane now alleged by us, be roughly divided into two classes: a class is centralized driving, namely drive long pass moving axis to drive the adhesion wheel on both sides with an electrical motor; Another kind of for driving, the i.e. adhesion wheel on both sides respectively use a direct motor drive respectively.Medium and small crane in bridge type more employing drg, retarder and motor unit incorporated " three-in-one " type of drive, the ordinary bridge crane of big elevating capacity is for ease of install and adjust, and actuating device often adopts universal coupling.
One of parts important in driving a vehicle when hanging jaw arrangement, but still there is certain deficiency in the existing jaw arrangement that hangs, the existing jaw arrangement that hangs is at crawl article, usually because the polarization hanging pawl is poor, and crawled article are come from hanging pawl disengaging, accidentally also likely cause the injures and deaths of personnel.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem proposed in above-mentioned background technology, the invention provides a kind of driving with hanging jaw arrangement, grasping part at claw hook is provided with claw, makes the good positioning effect of hanging pawl, article are not easy to come from hanging pawl disengaging.
The technical solution adopted for the present invention to solve the technical problems is: a kind of driving is with hanging jaw arrangement, comprise four claw hooks be oppositely arranged between two, the top of each claw hook, middle part and afterbody all offer pin hole, the pin of the sheathed fixed cover in middle part is provided with in four pin holes of corresponding position, four claw hook tops, in the middle part of four claw hooks corresponding position two groups of pin holes in be provided with the pin of two sheathed fixed covers in middle part, the pin of two sheathed fixed covers in middle part is provided with in two groups of pin holes of four claw hook afterbody corresponding positions, the tail end of four claw hooks is provided with the claw for firmly grasping article.
Further restriction: in the middle part of four claw hooks corresponding position two groups of pin holes in fixed cover in the middle part of two pins arranging all offers connecting bore.
Further restriction: be connected with the wirerope for reducing angle between four claw hooks being oppositely arranged between two between the connecting bore that two fixed covers in the middle part of four claw hooks are offered.
Beneficial effect of the present invention: this driving, with hanging jaw arrangement, is provided with claw by the grasping part at claw hook, makes the good positioning effect of hanging pawl, article are not easy to come from hanging pawl disengaging, ensure that life security and the social property safety of operating personal; Simultaneously owing to being connected with the wirerope for reducing angle between four claw hooks being oppositely arranged between two between connecting bore that two fixed covers in the middle part of four claw hooks are offered, play the effect of second protection, safety factor is higher further.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is decomposition texture schematic diagram of the present invention.
In figure: 1, claw hook, 2, pin hole, 3, fixed cover, 4, pin, 5, claw, 6, connecting bore.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Driving is as depicted in figs. 1 and 2 with hanging jaw arrangement, comprise four claw hooks 1 be oppositely arranged between two, the top of each claw hook 1, middle part and afterbody all offer pin hole 2, the pin 4 of the sheathed fixed cover 3 in middle part is provided with in four pin holes 2 of corresponding position, four claw hook 1 tops, in the middle part of four claw hooks 1 corresponding position two groups of pin holes 2 in be provided with the pin 4 of two sheathed fixed covers 3 in middle part, the pin 4 of two sheathed fixed covers 3 in middle part is provided with in two groups of pin holes 2 of four claw hook 1 afterbody corresponding positions, the tail end of four claw hooks 1 is provided with the claw 5 for firmly grasping article.
Wherein in the middle part of four claw hooks 1 corresponding position two groups of pin holes 2 in arrange two pins 4 in the middle part of fixed cover 3 on all offer connecting bore 6.The wirerope for reducing angle between four claw hooks 1 being oppositely arranged between two is connected with between the connecting bore 6 that two fixed covers 3 in the middle part of four claw hooks 1 are offered.
This driving, with hanging jaw arrangement, by being provided with claw 5 in the grasping part of claw hook 1, makes the good positioning effect of hanging pawl, and article are not easy to come from hanging pawl disengaging, ensure that life security and the social property safety of operating personal; Simultaneously owing to being connected with the wirerope for reducing angle between four claw hooks being oppositely arranged between two between connecting bore that two fixed covers 3 in the middle part of four claw hooks 1 are offered, play the effect of second protection, safety factor is higher further.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine its technical scope according to right.
