Abstract
The utility model relates to a key component of a lifting appliance, particularly relates to a crane hook, and aims to provide an improvement of a crane hook. The crane hook can be adaptable to various hanging positions, and is safe in using, convenient in operation, simple in structure and easy in manufacturing. The technical scheme of the utility model includes that the crane hook is positionedat the front end of a crane cantilever, and is characterized in that the top end of a hanging handle of the crane hook vertically upwardly passes through a U-shaped sheet and then is inserted and positioned in an internal slotted hole of a positioning block, two parallel sheets of the U-shaped sheet are hinged at the front end of the crane cantilever through a pin shaft, and a rotatable positioning structure is formed between the top end of the hanging handle of the crane hook and the internal slotted hole of the positioning block through a group of roll balls.
Description
Technical field
The utility model relates to a kind of critical component of weight-lifting equipment, specifically is the suspension hook of loop wheel machine.
Background technology
Loop wheel machine is widely used weight-lifting equipment, and is indispensable especially in vehicle maintenance and repair and metal work place.Suspension hook is to be used to collude the parts of hanging weight and bearing weight weight on the loop wheel machine.In the structure (as shown in Figure 3) of existing loop wheel machine, suspension hook 1 all is fixed on the front end of loop wheel machine cantilever 2 by load-bearing chain 6.The shortcoming of this kind structure is that suspension hook can not be around the chain line of centers rotation perpendicular to horizontal surface; When hanging the lift heavy thing, heavy-duty ropes or chain can only could be hung in the suspension hook in certain angle.Because what need lifting all is weight, heavy-duty ropes or chain generally all have certain diameter and weight; Therefore, operating personal is often felt inconvenience, the working strength when also having increased operation when the operation loop wheel machine.
The utility model content
The purpose of this utility model is to overcome the deficiency that the above-mentioned background technology exists, and a kind of improvement of loop wheel machine suspension hook is provided, and this suspension hook should be able to be applicable to that various extensions hang the position, has safe in utilization, convenience operation, and simple in structure, easy to manufacture.
The technical solution adopted in the utility model is: a kind of loop wheel machine suspension hook is positioned at the front end of loop wheel machine cantilever; It is characterized in that hanging of this suspension hook was inserted and positioned on again in the interior slotted eye of a positioning block after a U-shaped sheet was vertically up passed through on the handle top, two parallel plates of U-shaped sheet are hinged on the front end of loop wheel machine cantilever by a bearing pin; Suspension hook hangs in the position, top of handle and the locating piece between the slotted eye also by one group of ball and forms between the two rotatable location structure.
Described rotatable location structure is: the outer circumference surface that hangs position, handle top is shaped on a circle ball grooves, the inner peripheral surface of slotted eye is shaped on the corresponding ball grooves of a circle in the locating piece, described one group of ball embeds two ball grooves simultaneously, has realized the rotating location between suspension hook and the locating piece.
The beneficial effects of the utility model are: owing to suspension hook is rotatably positioned on the U-shaped sheet of loop wheel machine by one group of ball, thereby suspension hook can rotate around the handle line of centers that hangs perpendicular to horizontal surface neatly; During use no matter heavy-duty ropes or chain in which angle can both hang easily in the suspension hook, and use fool proofly, labour intensity also obviously reduces; In addition, because structure design uses simply again, it is also easy to make, so cost is also low.
Description of drawings
Fig. 1 is the perspective view that adopts loop wheel machine of the present utility model.
Fig. 2 is the main TV structure scheme drawing of amplification of the present utility model.
Fig. 3 is the perspective view of existing loop wheel machine.
The specific embodiment
As shown in Figure 3, the conventional structure of loop wheel machine comprises that the bottom is equipped with pivotally attached column on the base, base of road wheel, a hinged cantilever on the described column, a suspension hook is located on the cantilever top, other has the two ends of an oil cylinder to be hinged on respectively on the column and on the cantilever, and oil cylinder just can make cantilever rotate to promote weight around hinge-point when starting.
In the utility model, the handle top 1-1 that hangs of this suspension hook makes cylindric, be inserted and positioned on again in the interior slotted eye of a positioning block 5 after up passing through the position, plane in the middle of the U-shaped sheet 3, in this position, top of hanging handle and the locating piece between the slotted eye also by one group of ball, 4 formation rotating location structure between the two.
Described location structure is: the outer circumference surface that hangs position, handle top is shaped on a circle ball grooves (being linked to be a circle around outer circumference surface), the inner peripheral surface of slotted eye is shaped on the corresponding ball grooves of a circle in the locating piece, one group of ball embeds two ball grooves simultaneously, has realized the rotating location of suspension hook and locating piece.During concrete the installation, ball can be imported from the lateral opening 5-2 of locating piece 5 one by one, treat that all balls all enter assigned address after, screw in from screw 5-1 with a screw, and then sealed lateral opening 5-2, the control position that all balls are located reliably.Also as can be known, after two parallel plates of described U-shaped sheet 3 up bend, be hinged on the front end of loop wheel machine cantilever 2 by a bearing pin among the figure.
Claims (2)
1, a kind of loop wheel machine suspension hook is positioned at the front end of loop wheel machine cantilever; It is characterized in that hanging of this suspension hook was inserted and positioned on again in the interior slotted eye of a positioning block (5) after a U-shaped sheet (3) was vertically up passed through on handle top (1-1), two parallel plates of U-shaped sheet are hinged on the front end of loop wheel machine cantilever by a bearing pin; Suspension hook hangs in the position, top of handle and the locating piece between the slotted eye also by one group of ball (4) and forms between the two rotatable location structure.
2, a kind of loop wheel machine suspension hook according to claim 1, it is characterized in that described rotatable location structure is: the outer circumference surface that hangs position, handle top is shaped on a circle ball grooves, the inner peripheral surface of slotted eye is shaped on the corresponding ball grooves of a circle in the locating piece, described one group of ball embeds two ball grooves simultaneously, has realized the rotating location between suspension hook and the locating piece.
