Description

A kind of pallet lifting appliance

Technical field

The utility model relates to a kind of lifting appliance, particularly a kind of pallet lifting appliance when pallet implement is changed.

Background technology

At present pallet is implemented to change and realize by steel rope, one of steel rope hangs on the travelling crane hook earlier, the other end by another workman by two the wheel axles of hand with steel wire penetrating chassis one side, the axle of two wheels of pallet is caught, pass a workman on the chassis, steel rope is hung on the suspension hook of driving.The chassis opposite side also is by artificial steel rope to be caught the axle of chassis wheel, thereby by two steel ropes of symmetry whole pallet is caught, and realizes the replacing of driving to chassis.The steel rope at two ends can produce bigger thrust to the pallet breast board when changing chassis like this, the heavy more thrust of chassis is also big more, not only bigger destructive effect to being fastened with of breast board on the chassis, also can make the steel rope that contacts with the chassis breast board that bigger wearing and tearing take place, thereby have certain potential safety hazard.

And need drive a vehicle worker and several each and every one professional crane man of the operation of this replacing chassis carries out the contact operation and finishes, therefore used time of this replacing chassis is longer, and crane man needs well muscle power could obtain to change than faster chassis speed, there is certain potential safety hazard again in this simultaneously, therefore lacks the device of the safety quick replacing pallet of a kind of energy at present.

The utility model content

For addressing the above problem, the utility model provides a kind of pallet lifting appliance, can implement the replacing of pallet safely and fast with the pallet lifting.

For achieving the above object, pallet lifting appliance of the present utility model comprises two movable hooks and a crossbeam, and described two movable hooks are installed in the two ends of described crossbeam respectively; Described movable hook comprises vertical anchor shaft, mobile axle sleeve, first hook and second hook, the top of described vertical anchor shaft is fixed on the described crossbeam, described shifting axle cover is sleeved on described vertical anchor shaft, and can move up and down by described relatively vertical anchor shaft, the upper end of described first hook and second hook is connected with described crossbeam by bearing pin, and the middle part of described first hook and second hook is connected with described shifting axle cover by connecting rod respectively.

Pallet lifting appliance of the present utility model, also comprise two operating handles, two described operating handles lay respectively at the two ends of described crossbeam, and the end of described operating handle is connected with described crossbeam by bearing pin, and described operating handle is connected with described shifting axle cover by connecting rod.

The two ends of described crossbeam have been respectively arranged with hanger.

Adopt pallet lifting appliance of the present utility model, can reduce and change the consuming time of pallet, reduced labor intensity of operating personnel, increase work efficiency, reduced the danger coefficient of execute-in-place simultaneously.

The specific embodiment

Fig. 1 is the block diagram of pallet lifting appliance of the present utility model, and Fig. 2 is the plan sketch of pallet lifting appliance of the present utility model, and Fig. 3 is the left view of pallet lifting appliance among Fig. 2.Shown in Fig. 1～3, pallet lifting appliance of the present utility model comprises two movable hooks 10 and a crossbeam 20, and described two movable hooks 10 are installed in the two ends of described crossbeam 20 respectively; Described movable hook 10 comprises vertical anchor shaft 11, mobile axle sleeve 12, first hook, 13 and second hook 14, the top of described vertical anchor shaft 11 is fixed on the described crossbeam 20, described mobile axle sleeve 12 is sleeved on described vertical anchor shaft 11, and can move up and down by described relatively vertical anchor shaft 11, the upper end of described first hook 13 and second hook 14 is connected with described crossbeam 20 by bearing pin 111, and the middle part of described first hook 13 and second hook 14 is connected with described mobile axle sleeve 12 by connecting rod 131,132 respectively.

The two ends of described connecting rod 131,132 are connected with second hook 14 and described mobile axle sleeve 12 with described first hook 13 by bearing pin or hinge respectively, to keep alerting ability in relative rotation.When the described relatively vertical anchor shaft 11 of described mobile axle sleeve 12 moves down, promote described first hook, 13 and second hook 14 by two connecting rods 131,132 and rotate and open, so that described first hook, 13 and second hook 14 hangs on the axle of two wheels of pallet to be replaced around bearing pin 111.

The top of described vertical anchor shaft 11 the mode on the described crossbeam 20 of being fixed on can adopt welding fixing, also can adopt be threaded, other fixed forms such as bolted connection.

Be the handled easily personnel operation, pallet lifting appliance of the present utility model also comprises two operating handles 14, lay respectively at the two ends of described crossbeam 20, the end of described operating handle 14 is connected with described crossbeam 20 by bearing pin, and described operating handle 14 is connected with described mobile axle sleeve 12 by connecting rod 141.The two ends of described connecting rod 141 are connected with described mobile axle sleeve 12 with operating handle 14 by bearing pin respectively.The point of connection position of described connecting rod 141 and described operating handle 14 is reasonable to be between the mid point and crossbeam 20 point of connection of operating handle 14.Most preferred point of connection position be from crossbeam 20 point of connection 1/3rd operating handle length places.

When operating personal is depressed operating handle 14, connecting rod 141 drives mobile axle sleeve 12 and moves down, and drives described first hook, 13 and second hook 14 simultaneously and separately makes angle become big, and movable hook 10 opens.Otherwise when promotion operating handle 14 made progress, described first hook, 13 and second hook, 14 angles diminished movable hook 10 closures.

The two ends of described crossbeam 20 have been respectively arranged with hanger 21, are used for reeve 100, convenient driving lifting.

Fig. 4 is the scheme drawing of pallet lifting appliance running condition of the present utility model, and Fig. 5 is the left view of pallet lifting appliance running condition among Fig. 4.Shown in Figure 4 and 5, described first hook, 13 and second hook 14 be hung on the axle of 200 two wheels of pallet to be replaced.At first operating personal is depressed operating handle 14, after treating two of movable hook 10 hooks promptly first hook, 13 and second hook 14 being positioned at that 200 two wheels of pallet are other and becoming, dotted line state as shown in Figure 5, operating personal upwards lifts operating handle 14 then, first hook, 13 and second hook 14 is hung on the axle of 200 two wheels of pallet, operating personal leaves then, and driving just can begin to lift by crane pallet 200.
