Detailed Embodiments

[0025] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0026] As Figures 1 to 7As shown in the figure, an embodiment of the present invention provides a remote-controlled forklift truck for vehicles, which includes a chassis 101, on which a vertical arm 1 is vertically arranged. A support frame 4 is slidably arranged at the bottom of the vertical arm 1 through a reciprocating member. A roller 401 is arranged at one end of the support frame 4 away from the chassis 101; a hydraulic drive unit, which includes a lifting arm 2 slidably arranged in the vertical arm 1 through a lifting unit, a mounting frame 3 arranged on the lifting arm 2 through a transverse movement unit, and a hydraulic source component arranged on the chassis 101. Fork arms 301 are arranged on the mounting frame 3 in a mirror image manner. A storage groove 302 is formed on each fork arm 301. The support frame 4 is located in the corresponding storage groove 302. The hydraulic source component is respectively drivingly connected to the lifting unit and the transverse movement unit; a direction control unit, which includes a control member rotatably arranged on the chassis 101 and a direction wheel 505 rotatably arranged at the bottom of the control member; an electric control unit, which is arranged on the chassis 101 and is electrically connected to the reciprocating member, the hydraulic source component and the control member, and is used to drive each component to work together.

[0027] The detailed working process of this embodiment is as follows: By setting an electric control unit and electrically connecting it to the reciprocating member, the hydraulic source component and the control member. Through the electric control unit, the operator can remotely control the sliding of the support frame 4 of the forklift truck, the lifting and lowering of the lifting arm 2, the transverse movement of the fork arms 301, etc. Whether the forklift truck gets on and off the carriage or conducts handling operations on the goods in the carriage, there is no need for the operator to perform close-range operations near the forklift truck, thus avoiding the harm caused to the operator by possible collisions, tipping and other dangers during the working process of the forklift truck. At the same time, under the setting of the transverse movement unit, when the forklift truck rises to the height of the carriage, it is pulled into the carriage by controlling the transverse movement unit, avoiding the need to manually push the forklift truck into the carriage and reducing the problem of tipping and rolling over of the forklift truck when it is near the edge of the carriage.

[0028] The reciprocating member is used to control the support frame 4 to move away from or close to the fork arms 301, realizing the self-lifting function of the forklift truck. When the forklift truck lifts itself to the carriage, it is necessary to drive the support frame 4 in the direction away from the fork arms 301 to avoid interference.

[0029] In order to protect each component on the chassis 101, a housing 100 for protecting each component is installed on the chassis 101.

[0030] As Figure 3 And Figure 4 As shown in the figure, the reciprocating member includes two second drive sources 601 arranged on the chassis 101 in a mirror image manner and a sheave 6 fixedly arranged on the corresponding second drive source 601. A steel wire rope 603 is wound around each sheave 6. Each end of each steel wire rope 603 is respectively arranged at the corresponding end of the support frame 4.

[0031] The detailed working process of this embodiment is as follows: The second driving source 601 arranged on the chassis 101 through two mirrors helps to provide a stable driving force. By the cooperative work of the two driving sources, the sliding of the support frame 4 can be made more stable, avoiding problems of uneven force and inclination that may be caused by single-sided driving. By using the steel wire rope 603 as the transmission component, it has high strength and wear resistance, can withstand large tensile forces and repeated stretching movements. The steel wire rope 603 is wound around the sheave 6 for one to two turns, and then the two ends of the steel wire rope 603 are respectively connected to the corresponding ends of the support frame 4. When the sheave 6 rotates, it will traction the steel wire rope 603, thereby driving the support frame 4 to approach or move away from the fork arm 301.

[0032] In order to avoid the steel wire rope 603 from becoming loose or worn after long-term use and affecting the transmission, in this embodiment, a tension adjusting member 602 is arranged at one end of the support frame 4 away from the fork arm 301, and one end of the steel wire rope 603 is connected to the tension adjusting member 602 to ensure the tension of the steel wire rope 603.

[0033] The second driving source 601 in this embodiment is a reduction motor, and in other embodiments, a suitable driving source can be selected according to actual situations.

[0034] As Figure 6 shown, the lifting arm 2 includes a first lifting frame 305 and a second lifting frame 201 arranged on the top of the first lifting frame 305. Two groups of first bearings 304 are arranged on both sides of the first lifting frame 305 in a mirror image manner, and each first bearing 304 is in contact with the inner wall of the vertical arm 1 respectively.

[0035] The detailed working process of this embodiment is as follows: With the arrangement of the first bearings 304, the first bearings 304 are respectively in contact with the inner wall of the vertical arm 1, providing a good guiding effect for the lifting of the lifting arm 2. At the same time, the use of bearings can convert sliding friction into rolling friction, greatly reducing the wear between the lifting arm 2 and the vertical arm 1.

[0036] As Figure 6 shown, the lifting unit includes a lifting oil cylinder 204 arranged in the lifting arm 2. The bottom of the lifting oil cylinder 204 is arranged on the chassis 101, and its output end is connected to the top of the second lifting frame 201.

[0037] The detailed working process of this embodiment is as follows: With the arrangement of the lifting oil cylinder 204, the lifting of the lifting arm 2 is controlled through the lifting oil cylinder 204.

[0038] As Figure 5As shown in the figure, the lateral translation unit includes a scissors frame 8 with one end disposed inside the first lifting frame 305, and a hydraulic cylinder 306 disposed on the mounting frame 3. The other end of the scissors frame 8 is disposed on the mounting frame 3. The scissors frame 8 includes a fixed end and a movable end. Second bearings 801 are disposed at the movable ends. Each second bearing 801 is respectively disposed inside the corresponding mounting frame 3 and the first lifting frame 305. The fixed ends are respectively disposed inside the first lifting frame 305 and the mounting frame 3. The output end of the hydraulic cylinder 306 is connected to the movable end of the scissors frame 8.

[0039] The detailed working process of this embodiment is as follows: The scissors frame 8 is divided into a fixed end and a movable end. The fixed ends are respectively fixedly disposed inside the corresponding first lifting frame 305 and the mounting frame 3, and second bearings 801 are installed at the movable ends. The second bearings 801 are respectively located inside the corresponding first lifting frame 305 and the mounting frame 3. The scissors frame 8 arranged in this way has good extensibility and stability. It can achieve a large range of lateral movement in a relatively small space. By the relative rotation between the various rods, the overall length is changed, thereby driving the mounting frame 3 to perform lateral translation. At the same time, when bearing a large load, the force can be evenly distributed to each rod, ensuring the smoothness and reliability of the lateral translation process. Using the hydraulic cylinder 306 as the driving source can provide a powerful and stable driving force to drive the scissors frame 8. Through the cooperation between the scissors frame 8 and the lifting arm 2, the forklift can be flexibly operated in three-dimensional space.

[0040] As Figure 2 and Figure 6 As shown in the figure, the hydraulic source component includes a hydraulic tank 901 disposed on the chassis 101 and a hydraulic pump 9 disposed on the hydraulic tank 901. The output end of the hydraulic pump 9 is provided with a first control valve 902 and a second control valve 903. The first control valve 902 is connected to the lifting cylinder 204, and the second control valve 903 is connected to the hydraulic cylinder 306.

[0041] The detailed working process of this embodiment is as follows: By connecting the lifting cylinder 204 and the hydraulic cylinder 306 through the first control valve 902 and the second control valve 903 respectively, independent control of the lifting unit and the lateral translation unit is achieved. According to the actual operation requirements, the two control valves can be adjusted respectively to precisely control the actions of the lifting cylinder 204 and the hydraulic cylinder 306, thereby realizing the lifting and lowering of the lifting arm 2 and the lateral translation of the mounting frame 3. This independent control method improves the flexibility and accuracy of forklift operation and can better adapt to different working scenarios.

[0042] As Figure 3As shown in the figure, the control member includes a connecting shaft 501 rotatably arranged on the chassis 101 and a first driving source 502 fixedly arranged on the chassis 101. A control arm 5 is arranged at the upper end of the connecting shaft 501, a steering wheel 505 is arranged at the bottom end of the connecting shaft 501, sprockets 503 are arranged on both the connecting shaft 501 and the output end of the first driving source 502, and a chain 504 is arranged on the two sprockets 503.

[0043] The detailed working process of this embodiment is as follows: The connecting shaft 501 is rotatably arranged on the chassis 101, and this design provides a basic rotating structure for the direction control of the forklift. By rotating the connecting shaft 501, the steering wheel 505 at the bottom end can be driven to change the direction, so as to adjust the driving direction of the forklift. With the setting of the first driving source 502, by controlling the operation of the first driving source 502, the connecting shaft 501 is driven to rotate through the transmission of the sprockets 503 and the chain 504, and finally the direction of the steering wheel 505 is changed, thereby reducing or directly replacing the manual steering action. With the setting of the first driving source 502, a dual-control mode that can be used both electrically and manually is realized, and remote over-control steering can be implemented, and manual precise operation can be carried out when needed.

[0044] The first driving source 502 in this embodiment is a motor, and a suitable driving source can be selected according to actual conditions in other embodiments.

[0045] As Figure 2 shown, adjustable hydraulic pressure sensors are arranged at the output ends of the first control valve 902 and the second control valve 903.

[0046] The detailed working process of this embodiment is as follows: Due to the setting of the transverse moving member, when the scissors lift 8 is opened, the distance between the goods and the vehicle body is far, the force arm is large, and the vehicle body and the bottom will be subjected to greater stress, resulting in a reduction in the load capacity. With the setting of the adjustable hydraulic pressure sensor, the hydraulic pressure at the output ends of the first control valve 902 and the second control valve 903 can be monitored in real time. When the pressure of the hydraulic system exceeds the preset safety value due to reasons such as excessive load, the sensor will send a signal in time. The control system of the forklift can take corresponding measures according to this signal, such as restricting the actions of the lifting cylinder 204 or the hydraulic cylinder 306, to avoid damage to hydraulic components due to excessive pressure, such as cylinder bursting, oil pipe rupture or even rollover, and effectively protect the safety of the hydraulic system and the overall structure of the forklift.

[0047] As Figure 2 shown, a hub motor is arranged inside the steering wheel 505.

[0048] The detailed working process of this embodiment is as follows: The hub motor is integrated inside the steering wheel 505, and the structure is relatively independent, reducing the mutual influence between transmission components.

[0049] As Figure 2As shown, the electronic control unit includes a remote control module, a receiving module, a control circuit, and a power supply module. The first drive source 502, the second drive source 601, the hydraulic pump 9, and the in-wheel motors are all electrically connected to the control circuit.

[0050] The detailed working process of this embodiment is as follows: Under the setting of the electronic control unit, the electronic control unit is provided with a remote control module and a receiving module, enabling the operator to remotely control the forklift at a certain distance. The remote control module is used to send control instructions, and the receiving module is responsible for receiving signals from the remote control end. This design greatly improves the operation safety. The operator does not need to operate closely near the forklift, avoiding the harm caused to the operator by possible collisions, falling goods, etc. during the operation of the forklift. At the same time, remote operation also increases the operation flexibility. The operator can choose a more favorable position to observe the working conditions of the forklift, thereby more accurately controlling the actions of the forklift.

[0051] The control circuit is electrically connected to the first drive source 502, the second drive source 601, the hydraulic pump 9, and the in-wheel motors to achieve precise control of these components. Through the control circuit, according to the received instructions, the working states of each drive source and motor can be adjusted. For example, control the first drive source 502 to rotate the connecting shaft 501 to change the driving direction of the forklift, control the second drive source 601 to adjust the position of the support frame 4, control the hydraulic pump 9 to provide appropriate pressure and flow rate for the hydraulic system, and control the in-wheel motors to drive the steering wheel 505. This precise control can ensure the coordinated operation of each action of the forklift, improving the working efficiency and operation accuracy of the forklift.

[0052] The above electronic control unit technology is relatively mature, and its function is a conventional control circuit. The principle of its implementation will not be elaborated in detail in this embodiment.

[0053] The implementation principle of this application embodiment is as follows:

[0054] When it is necessary to move the forklift into the carriage for operation, first move the forklift to the rear side of the carriage body 111, and then control the scissor lift 8 to open, so that the fork arm 301 extends away from the forklift body, as Figure 7 shown. Then control the lifting cylinder 204 to lift the fork arm 301 so that its height exceeds the bottom surface of the carriage. Then drive the in-wheel motors forward so that the fork arm 301 enters the carriage. Stop when the vertical arm 1 is close to the side of the carriage. At the same time, drive the second drive source 601 to control the support frame 4 to move away from the fork arm 301 to the limit position. Then control the lifting cylinder 204 to contract. At this time, since the fork arm 301 abuts against the bottom surface of the carriage, when the lifting cylinder 204 contracts, the forklift body can be lifted until the support frame 4 exceeds the bottom surface of the carriage. Then control the second drive source 601 to flip, reset the support frame 4, control the scissor lift 8 to retract, and retract the forklift body suspended outside the carriage into the carriage. The above operations are all remotely controlled.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
