[0043] In the embodiments of the present application, the bearing member 200 is used to bear the bearing object which needs to be lifted or moved, and the bearing object can be a person or goods. The fork member 100 is used to lift or move the bearing member 200, wherein the fork 110 is used to implement a specific lifting action, the bearing seat 210 is used to implement a specific bearing action, and the fixing seat 220 is used to fix the fork 110. The fixing seat 220 is arranged at the bottom of the bearing seat 210, which is beneficial to the insertion of the fork 110. When the fork 110 is inserted into the fixing seat 220, the fork 110 can limit the freedom degree of the bearing member 200 in the left-right direction and the rotation freedom degree through the fixing seat 220. When the fork 110 is completely inserted into the bottom of the bearing seat 210, the positioning part 111 abuts against the bearing seat 210, and the extension part 230 is extended to abut against the limiting block 120, so that the positioning part 111 can limit the displacement of the bearing member 200 in the direction towards the positioning part 111, and the limiting block 120 can limit the displacement of the bearing member 200 in the direction away from the positioning part 111, so that all the freedom degrees of the bearing member 200 relative to the fork member 100 are limited, the relative position between the bearing member 200 and the fork member 100 cannot be changed, the bearing member 200 cannot shake on the fork member 100, and the safety is high. When the forklift is applied to high construction, the safety of construction can be ensured.

[0044] In some embodiments of the present application, the extension part 230 includes a fixed sleeve 231, an extension rod 232 and a driving element (not shown in the figure). The extension rod 232 is arranged on the fixed sleeve 231 in an extendable manner, and is arranged vertically and can be extended in the up-down direction. The driving element is used to drive the extension rod 232 to extend. The forklift-in-position sensor 211 is further arranged on the bearing member 200. When the fork 110 is not inserted into the bottom of the bearing member 200, the extension part 230 is in a retracted state. When the forklift-in-position sensor 211 senses that the fork 110 reaches a predetermined position, the driving element drives the extension rod 232 to extend and abut against the limiting block 120, so that the limiting block 120 can limit the displacement of the bearing member 200 in the direction away from the positioning part 111. After the fork reaches the above-mentioned predetermined position, the positioning part 111 abuts against the bearing seat 210, so that the positioning part 111 can limit the displacement of the bearing member 200 in the direction towards the positioning part 111, and the freedom degree of the bearing member 200 in the front-rear direction is limited. The bearing member 200 cannot swing in the front-rear direction when it is forked by the forklift, and the safety is high.

[0045] In order to save cost and simplify structure, in some embodiments, the telescopic part 230 comprises a fixed sleeve 231 and a telescopic rod 232, the telescopic rod 232 is telescopically arranged on the fixed sleeve 231, the telescopic rod 232 is vertically arranged and can be telescopically arranged in the up-down direction, the limiting stopper 120 comprises an inclined surface 121 and a limiting surface 122, the inclined surface 121 is used for pushing the telescopic part to retract, and the limiting surface 122 is used for abutting against the telescopic part 230 to limit the displacement of the bearing member 200 away from the positioning part 111. Specifically, when the fork 110 is not inserted into the bottom of the bearing member 200, the telescopic part 230 is in an extended state and can be telescopically arranged under the action of an external force, when the fork member 100 moves towards the bearing member 200, the inclined surface 121 of the limiting stopper 120 faces the telescopic part 230, after the inclined surface 121 of the limiting stopper 120 contacts the telescopic rod 232, during the continuous forward movement of the fork member 110, because the height of the part where the inclined surface 121 contacts the telescopic rod 232 gradually increases, the limiting stopper 120 will exert an upward force on the telescopic rod 232 to lift the telescopic rod 232, so that the telescopic rod 232 retracts, after the limiting stopper 120 passes the position of the telescopic part 230, the limiting stopper 120 no longer pushes against the telescopic rod 232, the telescopic rod 232 can extend under the action of gravity and abut against the limiting surface 122 of the limiting stopper 120, so that the limiting stopper 120 can limit the displacement of the bearing member 200 away from the positioning part 111, at this time, the positioning part 111 abuts against the bearing seat 210, thereby limiting the displacement of the bearing member 200 towards the positioning part 111, so that the freedom of the bearing member 200 in the front-back direction is limited, after the bearing member 200 is lifted by the fork member 100, the bearing member 200 will not swing in the front-back direction, and the safety is higher. By arranging the inclined surface 121 and the limiting surface 122 on the limiting stopper 120, the fork member 100 can naturally lift the telescopic part 230 during the movement process, and make the telescopic part 230 naturally fall and extend after the limiting stopper 120 passes, so as to lock the bearing member 200, the structure is reliable, the operation is simple, the quick locking of the bearing member 200 can be realized, and the work efficiency is improved.

[0046] In order to further improve the reliability of the equipment, in the embodiments of the present application, the telescopic part 230 further comprises a spring (not shown in the figure), the spring is sleeved on the telescopic rod 231, when the inclined surface 121 of the limiting stopper 120 lifts the telescopic rod 232 upwards, the spring will be compressed, after the limiting stopper 120 passes, the telescopic rod 232 automatically pops out under the action of the elastic force and abuts against the limiting surface 122, so as to lock the freedom of the bearing member 200 in the front-back direction, after the telescopic rod 232 pops out, because of the tensioning action of the spring, the telescopic rod 232 can maintain a relatively stable state and will not sway or swing up and down, and the safety is higher.

The embodiment of the present application greatly enhances the stability and safety of the fork member 100 when the fork member 100 forks the bearing member 200 by setting the fixing seat 220, the telescopic part 230 and the positioning part 111. On this basis, the safety of the bearing member 200 is further improved by setting the protective fence 240 around the periphery of the bearing member 200, so that the bearing member 200 can be used as a safety cage for manned construction at high altitudes, and the safety and reliability are high. The protective fence 240 comprises a closable protective door 241, which is convenient for workers to enter and exit, and the protective door 241 is provided with a door detection sensor 242 on one side to ensure that the protective door 241 is in a closed and locked state when the fork 110 is raised, further ensuring the safety of the bearing member 200, and the protective fence 240 is provided with a top touch detection sensor 243 on the top to prevent the bearing member 200 from being raised too high to touch the ceiling. Further, the bearing member 200 is provided with a fork in place sensor 211 at the bottom to ensure the accurate position of the fork when the fork member 100 is raised, further ensuring safety.

[0048] In the embodiment of the present application, under the support of the top touch detection sensor 243, it can be ensured that the operator and the bearing member 200 will not touch the ceiling or beam and other fixed structures during use when the forklift assembly is used for construction operation, further improving the safety factor. The fork in place sensor 211 is responsible for monitoring whether the bearing member 200 is accurately in place, so as to judge whether the lifting operation can be carried out under the premise of ensuring safety, and to comprehensively guarantee the safety and efficiency of operation.
