Abstract

The invention discloses an electric forklift without batteries. The electric forklift comprises an electric forklift body and further comprises a vertical rod, a cable relay device, a telescopic winder and a winder guide rail, wherein the vertical rod is arranged at the tail part of the electric forklift body; the cable relay device is installed at the top of the vertical rod, a cable is downwardsled out of the cable relay device to be electrically connected with a power circuit of the electric forklift body, and a cable is upwards led out of the cable relay device to be electrically connected with a cable of the telescopic winder; and the telescopic winder is arranged on the winder guide rail in a sliding mode. By means of the simple structure, when the electric forklift is used in a factory building, no battery module needs to be arranged in the electric forklift body, the problem of maintenance and replacement of battery modules caused by using an existing electric forklift with the batteries in the factory building is effectively solved, and then the use cost of the electric forklift is further saved.

Example Embodiment

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] The embodiment of the present invention discloses a battery-free electric forklift, which can realize the retracting and using of cables in a workshop through a retractable reel. The electric forklift body does not need to be equipped with a battery module, which effectively solves the problem of using belts in the workshop. The maintenance and replacement of battery modules caused by battery electric forklifts saves the cost of using electric forklifts.

[0024] The invention discloses a battery-free electric forklift, which includes an electric forklift 1, and also includes a vertical rod 2, a cable relay device 3, a telescopic reel 4 and a reel guide rail 5; the vertical rod 2 is installed at the tail of the electric forklift 1; The cable relay device 3 is installed on the top of the vertical pole 2, the cable relay device 3 leads downwards and the cable is electrically connected with the power circuit of the electric forklift 1, and the cable relay device 3 leads upwards the cable and the cable of the retractable reel 4 Electrical connection; the retractable cord reel 4 is slidably arranged on the cord reel guide rail 5.

[0025] In order to further optimize the above technical solution, the telescopic reel 4 is slidably arranged on the reel guide rail 5 through a sliding seat 6; the sliding seat 6 includes a base 61 and a pulley 62 arranged on the base 61 through a bearing; The cross section is circular, the pulley 62 is provided with an arc-shaped groove matching the outer contour of the reel guide 5, two pulleys 62 are provided, and they are respectively located on both sides of the reel guide 5, the reel guide 5 Clamp into the arc-shaped grooves of the pulleys 62 on both sides.

[0026] In order to further optimize the above technical solution, the reel guide rail 5 is installed on the top of the movable area of the electric forklift 1.

[0027] In order to further optimize the above technical solution, the reel guide rail 5 is installed on the roof of the factory 7 where the electric forklift 1 is located.

[0028] In order to further optimize the above technical solution, the reel guide rail 5 is an annular guide rail.

[0029] In order to further optimize the above technical solution, the reel guide rail 5 is a non-closed guide rail, and two ends of the reel guide rail 5 are provided with sliding seat limiters.

[0030] In order to further optimize the above technical solution, the sliding seat limiter is a baffle plate welded on both ends of the reel guide rail 5.

[0031] In order to further optimize the above technical solution, the cable relay device 3 is a junction box.

[0032] In order to further optimize the above technical solution, the telescopic cord reel 4 is a telescopic cord reel drum, and the telescopic cord reel drum adopts the giant brand ZYE 06-315/215 model hose reel drum.

[0033] In order to further optimize the above technical solution, the cable of the retractable cord reel 4 is electrically connected to the factory power supply.

[0034] working principle:

[0035] A vertical rod 2 is erected in the middle of the tail of the electric forklift 1, and a cable relay device 3 on the top of the vertical rod 2 connects the cables leading into the power circuit of the electric forklift 1 and the retractable cord reel 4 on the reel guide 5 on the top of the plant For laying out the cables, the electric connection between the power circuit on the electric forklift 1 and the retractable cables on the retractable cord reel 4 can be realized through the cable relay device 3.

[0036] The retractable cord reel drum is equipped with an automatic reel to retract and unwind the cable. When the electric vehicle moves, the retractable cord reel drum first slides on the reel guide rail 5 under the action of the sliding seat 6, When the distance reached by the electric forklift 1 continues to expand outward, the electric forklift 1 will drive the vertical rod 2 to drag the cable of the telescopic winding drum outwards, thereby releasing the cable; when the electric forklift 1 returns, this At this time, the pulling force of the electric forklift 1 to the cable will be lost, and the telescopic reel drum will rewind the cable. The telescopic cord-winding drum is an existing mature technology, and the principle of cord-winding is not repeated here.

[0037] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0038] The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined in this document can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown in this document, but should conform to the widest scope consistent with the principles and novel features disclosed in this document.
