Referring to fig. 1 and fig. 2, fig. 1 is a perspective view of a partial structure of a fork lift according to an embodiment of the present disclosure, and fig. 2 is a front view of the structure shown in fig. 1.

A fork lift is a crane for lifting high loads by means of a fork arm 6, which should first of all have a body carrying its weight and having mobility. Correspondingly, a lifting mechanism is arranged on the vehicle body, and the fork arm 6 can lift and drop the goods through the lifting mechanism.

The lifting mechanism has various realization modes, such as a screw rod lifting mechanism, a hydraulic lifting mechanism, an electric push rod lifting mechanism and the like, and different lifting mechanisms can adapt to different use scenes. In this embodiment, a lifting mechanism which is more suitable for small goods and is lighter is provided, and the lifting mechanism mainly comprises a door-shaped lifting frame. The door type crane can be provided with two vertical sliding rail door feet 1, the sliding rail door feet 1 can be regarded as a sliding rail which is vertically arranged, but the door type crane also has the supporting function of the support, and a cross rod 2 is connected between the two sliding rail door feet 1 to form a door type structure. It should be noted that, in order to make the fork-lift crane more portable, the door-shaped lifting frame can be made of aluminum.

All can set up slider connecting piece 3 on two vertical slide rail door feet 1, rethread slider connecting piece 3 forms horizontal slide rail 4 and two slide rail door feet 1 and is connected, and at this moment, 4 horizontal settings of horizontal slide rail just in time are perpendicular two slide rail door feet 1.

Further, the yoke 6 can be slidably connected to the lateral slide rail 4, so that the yoke 6 can be adjusted in left and right positions based on the lateral slide rail 4. During the concrete connection, a slider connecting piece can also be arranged on the transverse sliding rail 4, and the fork arm 6 is further connected with the slider connecting piece. In this embodiment, the delta block 5 is selected as a connecting member between the yoke 6 and the lateral slide rail 4, which is practical and simple.

The arrangement of the transverse slide rails 4 provides the fork arms 6 with a base for transverse adjustment, but in practical applications, the fork arms 6 carrying heavy goods are difficult to adjust manually. Accordingly, a corresponding transverse drive mechanism may be provided. The transverse driving mechanism is a driving mechanism which can provide transverse push-pull force to the fork arm 6, and when the transverse driving mechanism is specifically implemented, the transverse driving mechanism also has multiple implementation modes. For example, a combination of a motor and a lead screw can be provided, specifically, the motor can be connected with the lead screw arranged along the length direction of the transverse slide rail 4, a slide block is arranged on the lead screw, and the slide block is connected with the fork arm 6 to change the rotation of the motor into the transverse linear motion of the fork arm 6. Of course, there are other implementations, such as motor and telescopic link, motor and chain, etc.

The present embodiment provides a more preferable implementation manner, and the transverse driving of the fork arm 6 is realized by arranging the windlass 8, the wheel seat 7 and the transmission belt. The windlass 8 can be a small direct current speed reducing motor connected with a winding drum, and is arranged on the transverse sliding rail 4, and the wheel seat 7 is also arranged on the transverse sliding rail 4. The winch 8 and the wheel seat 7 can be connected in a winding way through a transmission belt to form a loop capable of being transmitted, and the fork arm 6 is connected with the transmission belt, so that the fork arm 6 can be driven along with the transmission belt when the transmission belt is transmitted.

Generally, the number of the fork arms 6 is more than one, and for a fork-lift crane equipped with two fork arms 6, two sets of the above-mentioned transverse driving mechanisms can be symmetrically arranged on the transverse slide 4, so that one fork arm 6 capable of being transversely adjusted is arranged on the left side and the right side of the transverse slide 4. When the lifting fork is used, two fork arms 6 are matched to lift or drop larger cargos, and one fork arm 6 can be used corresponding to one cargo.

The wheel seat 7 of the transverse driving mechanism on one side of the middle point of the transverse sliding rail 4 can be arranged at the end part of the transverse sliding rail 4, and the corresponding winch 8 can be arranged at any position of the side part of the transverse sliding rail 4 according to requirements, of course, the distance between the winch 8 and the wheel seat 7 is the length of the fork arm 6 which can be transversely adjusted, so that the winch 8 can be close to the middle point of the transverse sliding rail 4 as much as possible to increase the transverse adjustable distance of the fork arm 6. And for the transverse driving mechanism on the other side of the transverse sliding middle point, the transverse driving mechanism and the transverse driving mechanism on the opposite side are symmetrically arranged.

A fixed fork arm 6 can be arranged in the middle of the transverse sliding rail 4, the fixed fork arm 6 is fixedly connected to the midpoint of the transverse sliding rail 4, and the fixed fork arm 6 and the left and right movable fork arms 6 which can move transversely are matched to finish the transportation of various goods.

It should be noted that the three yokes 6 (the middle fixed yoke 6 and the left and right movable yokes 6) may be the preferred Z-shaped yoke 6 provided in this embodiment. The Z-shaped fork arm 6 is in a Z shape from the side, the top of the Z-shaped fork arm 6 is a horizontal connecting plate and can be conveniently connected with the delta pulley 5 in the embodiment, and the middle part and the bottom part are respectively provided with inclined plates as fork plates. Wherein, the fork board is not horizontal setting, but sets up the rising of certain inclination, forms the effect similar to the hook with the swash plate at middle part, can prevent that the goods is artificial to drop. It can be understood that the fork arms 6 arranged in the Z shape can make the center of gravity of the goods just fall under the installation part mechanically, and the stress condition is better.

Furthermore, when the alignment is carried out, an alignment sensor can be used. The alignment sensor can be arranged on the fork arm 6 or can move along with the fork arm 6, can detect whether the front of the fork arm 6 is right opposite to a target position, and can send a signal to the motor when deviating from the target position so as to correspondingly adjust the position of the fork arm 6 to realize alignment.

The above is a detailed description of the forklift provided in the embodiment of the present application, and the forklift includes a body, a lifting mechanism is disposed on the body, a lifting movable part of the lifting mechanism is connected to a horizontal sliding rail 4, and a fork arm 6 is slidably connected to the horizontal sliding rail 4; the device also comprises a transverse driving mechanism, wherein the fork arm 6 is connected with the transverse driving mechanism and can slide on the transverse sliding rail 4 based on the transverse driving mechanism.

It can be seen that, because the fork arm 6 is slidably connected with the transverse slide rail 4, the fork arm 6 can be driven to perform transverse position adjustment under the action of the transverse driving mechanism. Meanwhile, the transverse slide rail 4 is connected with a movable part of the lifting mechanism, so that the fork arm 6 can also lift up and down under the action of the lifting mechanism. When goods at the designated position are lifted or placed at the designated position, the positions of the fork arms 6 can be adjusted vertically and horizontally, and only the method for adjusting the position of the whole fork crane is needed when the goods are aligned, so that the aligning efficiency is greatly improved.
