Description

The pallet fork of fork truck and goods shelf unitized construction

Technical field

The utility model relates to pallet fork and the goods shelf unitized construction on the fork truck.

Background technology

Pallet fork and goods shelf that existing hand fork lifter is provided with are fixed to each other, transmission by the lifting mechanism on the door frame, pallet fork and goods shelf can together move up and down, and the pallet fork of this fork truck can only hold up goods from the bottom surface of goods, realizes the carrying to goods.For some special equipment, be provided with repeated hole in its both sides usually, the fork truck of said structure then can't utilize the repeated hole that rises of equipment both sides that it is carried.

The utility model content

The purpose of this utility model is to provide a kind of pallet fork and goods shelf unitized construction of fork truck, and it can utilize the repeated hole that rises of equipment both sides that it is carried with after the door frame of existing fork truck combines.

For achieving the above object, the utility model adopts following scheme: the pallet fork of fork truck and goods shelf unitized construction, include two pallet forks and a goods shelf, at the track that is provided with on the goods shelf more than two, two pallet forks cooperate with slide, on two pallet forks, all be installed with bearing with threaded hole, and the thread rotary orientation of the tapped bore of two pallet fork upper brackets is opposite, leading screw is housed on goods shelf, bearing on two pallet forks is contained on the leading screw, inboard at two pallet fork front ends respectively is fixed with a bolt, and two bolts are positioned opposite.The unitized construction of the pallet fork of above-mentioned formation and goods shelf is replaced pallet fork and goods shelf on the existing forklift door frame, drive the lifting of pallet fork and goods shelf by the lifting mechanism on the forklift door frame, can make fork truck have the slave unit both sides and play repeated hole its function that holds up.

By such scheme as seen, the fork truck that possesses the unitized construction of pallet fork provided by the utility model and goods shelf, when the equipment that both sides has been had repeated hole is carried, the bolt of two pallet fork front end positioned opposite is distinguished the repeated hole that rises of aligning equipment both sides, rotational lead screw, two bolts are moved in opposite directions stretched into two repeated holes respectively, by the lifting mechanism on the door frame pallet fork and goods shelf are together risen then, equipment can be held up and realize carrying.When equipment is transported to the appointed place, pallet fork and goods shelf are together fallen, the backward rotation leading screw oppositely moves two bolts again, and two bolts then can withdraw from repeated hole.

The utility model is rational in infrastructure, use is reliable, and it and existing fork truck are equipped with, and can solve the carrying problem of some special equipments.

The specific embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, the pallet fork of the fork truck that the utility model provides and goods shelf unitized construction, it includes two pallet forks 2 and a goods shelf 1, on goods shelf 1, be provided with four parallel track 1a, two pallet forks 2 respectively with wherein two track 1a bearing fits, be in the pallet fork 2 in left side and first and third track 1a bearing fit of several from top to bottom, be in the pallet fork 2 on right side and second, four track 1a bearing fit of several from top to bottom.

Referring to Fig. 2, Fig. 2 has illustrated to be in the pallet fork 2 in left side and the combination of goods shelf 1 among Fig. 1, and two pallet forks 2 are identical with the combination of goods shelf 1 among Fig. 1.As seen from Figure 2, the track 1a that goods shelf 1 is provided with is that the cross section is "T"-shaped chute, pallet fork 2 with the mode of track 1a bearing fit is: the slide block 8 with its bearing fit is housed in track 1a, tool bolt cap 8a on the slide block 8, bolt cap 8a passes pallet fork 2 backs and connects with nut 9, and pallet fork 2 is connected with slide block 8.All be connected with bearing with threaded hole 10 on two pallet forks 2, bearing 10 is an one with pallet fork 2, and the rotation direction of the screw thread of the tapped bore of two pallet forks, 2 upper brackets 10 is opposite.

In conjunction with Fig. 1, Fig. 2, be contained on the leading screw 3 at the bearing 10 that is equipped with on the goods shelf 1 on leading screw 3, two pallet forks 2, promptly the tapped bore of the bearing 10 on two pallet forks 2 cooperates with leading screw 3.The mode that leading screw 3 is located on the goods shelf 1 is: be provided with groove 1b at the middle part of goods shelf 1, bearing seat 5 is equipped with at the two ends in groove 1b respectively, and leading screw 3 is loaded on the bearing seat 5.On goods shelf 1, also open four through hole 1c, goods shelf 1 can be installed on the door frame of fork truck by through hole 1c.In addition, as seen from Figure 1, be fitted with rocking handle 4 at an end of leading screw 3.In addition, can also by being equipped with other driving device transmission gear or belt pulleys, also can realize the rotation of leading screw 3 at an end cogged or a belt pulley of leading screw 3.

Referring to Fig. 1, Fig. 3, respectively be fixed with a bolt 6 that is positioned opposite in the inboard of two pallet forks, 2 front ends, bolt 6 is cylindric, the front end tool chamfering of bolt 6.

In conjunction with Fig. 1, Fig. 2 as seen, rotation crank 4 makes leading screw 3 cws or rotates counterclockwise, can be by leading screw 3 driving support seat 10, make two pallet forks 2 and on bolt 6 move in opposite directions or oppositely move.

Referring to Fig. 1, Fig. 4, the front portion of bolt 6 has a groove 6a, and the bottom surface of groove 6a is the face of cylinder, is positioned at groove 6a rear side edge and is installed with block 7.The generation type of groove 6a is: make the diameter of the one section cylinder 6b in position that bolt 6 has groove 6a less than the diameter of bolt 6 base portions, and the axis runout of the axis of this section cylinder 6b and bolt 6 base portions.

The pallet fork that present embodiment provides and the unitized construction of goods shelf replace pallet fork and the goods shelf on the door frame of existing fork truck, and drive the lifting of pallet fork and goods shelf by the lifting mechanism on the existing forklift door frame, can make fork truck have the slave unit both sides and play repeated hole its performance that holds up.As seen from Figure 5, this fork truck is when carrying the used VS1 series middle switchgear of power supply industry, after bolt 6 enters a repeated hole 12 of VS1 series middle switchgear 11 both sides, location by block 7, can guarantee that groove 6a has aimed at the edge of repeated hole 12, after bolt 6 rose, groove 6a can closely engage with the edge that plays repeated hole 12, with the safety of guaranteeing to carry.When equipment is transported to the appointed place, when pallet fork and goods shelf were together fallen, the edge that groove 6a then can play repeated hole 12 separated, and 6 of bolts can withdraw from repeated hole 12 smoothly.
