Description

Technical Field

[0001] The utility model relates to the technical field of electric transport vehicles, in particular to an electric transport vehicle. Background Art

[0002] The electric transport truck is a small, convenient, flexible, heavy-duty, and durable cargo handling tool. In addition to the function of transporting goods, the transport truck has a hydraulic device between the chassis and the wheels to facilitate the lifting and lowering of goods. The vehicle can be easily pushed under the base of the cargo box, and then the chassis is raised by hydraulics to lift the goods, and the goods can be dragged to move. After arriving at the destination, the chassis is lowered by hydraulics, and the goods fall to the ground as well. The electric transport truck can be easily pulled out, eliminating the complicated process of manual handling and is widely used in logistics transportation.

[0003] For example, Chinese patent CN218290354U discloses an electric transport vehicle, including a transport frame and an auxiliary mechanism, which is symmetrically distributed on both sides of the transport frame. The auxiliary mechanism includes a mobile frame, a threaded rod, a rotating block and a limit rod. A connecting ring is provided below the rotating block, a connecting shaft is inserted between the rotating block and the connecting ring, the connecting ring is rotatably connected to the rotating block, and the connecting ring is fixedly connected to the side wall of the transport frame; a threaded rod is rotatably installed on a side of the rotating block away from the connection with the transport frame and a sliding rod is fixedly installed, the threaded rod and the sliding rod are spaced and parallel, the threaded rod is threadedly connected to the mobile frame, the threaded rod is inserted toward the inside of the mobile frame, the upper surface of the mobile frame has an embedded groove, and the inside of the embedded groove is rotatably connected to the limit rod.

[0004] However, in the prior art, when an electric transport truck is used to transport goods, it is necessary to push the handle so that the fork legs are located at the bottom of the goods, move the fork legs upward to fit the goods, and then pull the handle to move the goods. When the driving wheel is driven to move by the handle, the cylinder will also deflect multiple times. Over time, the cylinder and the entire oil pump are easily damaged, which greatly reduces the service life of the oil pump and the transport truck. In view of the above problems, an electric transport truck is proposed. Utility Model Content

[0027] Embodiment 2

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the utility model provides an electric transport vehicle, wherein a frame assembly 1 comprises a frame body 11, a connecting rod 15, a bracket 16 and a connecting rod 17, two fork legs 12 are symmetrically welded at both ends of the bottom of the frame body 11, the two ends of the bottom of the frame body 11 are fixedly installed with the two ends of the connecting rod 17, and the top of the frame body 11 is rotatably connected with the top of the piston rod 28, two rocker arms 14 are symmetrically arranged at both ends of the connecting rod 17, and one end of the two rocker arms 14 is rotatably connected with one end of the support plate 25, one end of the connecting rod 15 is rotatably connected with one end of the rocker arm 14, and the other end of the connecting rod 15 is rotatably connected with one end of the bracket 16, and one end of the bracket 16 is rotatably installed with two support wheels 13.

[0029] The effect achieved by the entire embodiment is that when the support plate 25 and the driving wheel 22 move / turn, the support plate 25 drives the connecting rod 15 and the support wheel 13 to move / turn through the rocker arm 14, and the hydraulic lifting system is used to realize the up and down lifting of the two fork legs 12. The driving wheel 22 and the support wheel 13 can control the moving speed and direction of the transport vehicle, and the moving and turning operations of the transport vehicle and the hydraulic lifting operations do not affect each other. At the same time, when turning, the driving wheel 22 turns first, and the support wheel 13 turns accordingly, thereby making the steering of the transport vehicle easier during movement.

[0030] The use method and working principle of the device: The electric transport vehicle is composed of a frame component 1 and a handle component 2. The hydraulic lifting system in the frame body 11 is used to realize the up and down lifting of the two fork legs 12 (the hydraulic lifting system is mainly composed of a hydraulic oil tank, a hydraulic oil pump and a control valve. The hydraulic oil tank is a place for storing hydraulic oil. The hydraulic oil pump is installed at the lower part of the oil tank. The hydraulic oil in the hydraulic oil pump can be transported to a high-pressure container through the work of the pump to form a liquid pressure of a certain pressure. The control valve is responsible for controlling the flow of hydraulic oil and the opening and closing of the valve, transferring the hydraulic oil into the hydraulic cylinder and controlling the piston movement of the hydraulic cylinder. The hydraulic cylinder is the lifting mechanism of the electric transport vehicle. The body is lifted to a certain height by compressing the hydraulic oil. When the operator needs to use the transport vehicle to transport the goods, the operator operates the control valve in the frame body 11, and the hydraulic oil pump presses the hydraulic oil into the hydraulic cylinder (cylinder barrel 26), and the piston 29 in the cylinder barrel 26 rises accordingly, and the piston rod 28 moves upward, thereby driving the fork legs 12 to move upward until the two fork legs 12 and the vehicle body reach the required height, which is convenient for transporting the goods. When the goods arrive at the destination and need to be landed, the operator only needs to operate the control valve in the frame body 11 (reverse the operating direction), and the hydraulic oil in the cylinder barrel 26 will flow back to the hydraulic oil tank, the piston 29 in the cylinder barrel 26 drops, the piston rod 28 moves downward, and the vehicle body drops accordingly, completing the unloading;

[0031] By setting the handle assembly 2, when the operator pulls the handle 24, the handle base 23 can be driven to move or deflect, and the handle base 23 can turn 180°. When the handle 24 drives the driving wheel 22 to move through the handle base 23, the cylinder 26 part does not rotate at this time. The advantage of this is that the friction between the piston 29, the piston rod 28 and the cylinder 26 is reduced, thereby reducing the wear of the internal seals, making the transport vehicle more durable.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
