Description

Fork truck Technical Field The utility model relates to the technical field of intelligent logistics equipment, in particular to a forklift structure suitable for a pallet in a shape like a Chinese character 'tian'. Background The forklift device is increasingly widely applied to carrying scenes such as storage, production lines and the like. The existing fork-lift truck is generally a fork-lift truck or a front fork-lift truck, however, when the fork-lift truck is adapted to a standard field-shaped cargo pallet (i.e. a field-shaped structure with a transverse partition plate at the bottom of the pallet), the fork-lift truck still faces the following defects that (1) the fork-lift truck generally integrates a fixed walking wheel set on a fork so as to ensure the movement stability. However, when the fork truck is used for forking the field-shaped pallet, the travelling wheels at the bottom of the fork truck can physically interfere with the transverse partition plate at the bottom of the pallet, so that the insertion action cannot be completed, and the fork truck cannot be suitable for the field-shaped pallet. (2) The front fork truck realizes carrying through the direct insertion tray clearance of fork tooth that stretches forward, but though the flexible Tian Zituo dish, its fork tooth can produce great overturning moment when bearing the goods, in order to balance the moment, load great balancing weight in automobile body rear end generally, leads to whole car weight and size to increase by a wide margin, can't adapt to narrow and small space. Therefore, there is a need to design a new forklift to overcome the above-mentioned drawbacks. Disclosure of utility model The utility model aims to provide a forklift, wherein a load wheel group at the front end of a fork arm assembly can extend or retract, the load wheel group at the front end of the fork arm assembly can retract to lift off the ground when in idle load, the front end of an extension arm is suspended to penetrate through a transverse gap of a Chinese character 'tian' shaped tray, interference is avoided, the fork arm is lifted by falling down through the load wheel group when in load, the load wheel is matched with a forklift body to directly bear the gravity of goods, additional counterweight balance is not needed, and the forklift can be adapted to a narrow space. In order to achieve the above purpose, the utility model provides a forklift, which comprises a forklift body, wherein a driving source is arranged on the forklift body; The fork arm assembly is arranged on one side of the vehicle body and comprises a connecting part connected with the driving source, and an extension arm fixedly arranged at the lower end of the connecting part, wherein the bottom of the extension arm is provided with a mounting groove which is pivotally connected with a load wheel set; a rotating member pivotally arranged on the connecting portion and hinged with the vehicle body, and The transmission piece is provided with a first end and a second end which are opposite, the first end is hinged with the rotating piece, and the second end is hinged with the load wheel group; when the driving source drives the connecting part to lift, the rotating piece rotates along with the lifting of the connecting part and drives the transmission piece to swing so as to drive the load wheel set to pivotally extend out of the mounting groove and press against the ground, and the cargo tray is jointly borne by the vehicle body and the load wheel set; When the driving source drives the connecting part to descend, the rotating part reversely rotates along with the descending of the connecting part and drives the transmission part to reversely swing so as to drive the load wheel set to reversely pivot and retract to the mounting groove, thereby suspending the mounting groove of the extension arm. Preferably, the bottom of the rear end of the extension arm is connected with a supporting wheel set, the bottom of the front end of the extension arm is connected with the load wheel set, the rear end is close to the connecting part, and the front end is far away from the connecting part; When the connecting part is lifted, the fork arm assembly rotates based on the supporting wheel set supported on the ground, the load wheel set pivotally extends out of the mounting groove and presses against the ground, the extending arm is further lifted, and the supporting wheel set is lifted off the ground; When the connecting part descends, the fork arm assembly reversely rotates based on the load wheel set supported on the ground, and the rotating part reversely rotates and drives the load wheel set to upwards pivot and retract to the mounting groove through the transmission part, so that the support wheel set is grounded and the front end of the extension arm is suspended. Preferably, the two extension arms are flush with each other and symmetrically arranged at the lower end of the connecting part; T
