DETAILED DESCRIPTION
[0021] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0022] like Figures 1 to 4 As shown, a fork assembly 10 of a transport truck of the present application includes: a base frame 11, a scissor fork assembly 13 is provided on the left and right sides of the base frame 11, and a jacking drive assembly 15 is provided. A jacking plate 16 is installed above the scissor fork assembly 13 to support the goods plugged in above, so that the above-mentioned scissor fork assembly 13 is driven by the jacking drive assembly 15 to jack up, thereby realizing the plugging and transporting of the goods.
[0023] Specifically, the above-mentioned jacking drive assembly 15 includes: a jacking motor 151, a jacking screw 152 and a screw nut 153. During installation, one end of the jacking screw 152 is rotatably connected to the support seat 12 provided in the base frame 11, and the other end is connected to the output shaft of the jacking motor 151, and the screw nut 153 is threadedly sleeved on the outer periphery of the jacking screw 152 and slidably connected to the base frame 11. The two scissors fork assemblies 13 are respectively arranged on both sides of the screw nut 153. The above-mentioned scissors fork assembly 13 includes: an inner fork arm 132 and an outer fork arm 133, and the inner fork arm 132 and the outer fork arm 133 are hingedly connected by a hinge shaft 131, so that relative rotation can be achieved. During installation, the lower end of the inner fork arm 132 is rotatably connected to the corresponding side of the screw nut 153 via the push shaft 134, and the upper end thereof is rotatably connected to the lower side of the lifting plate 16 via the rotating shaft 135. The lower end of the outer fork arm 133 is rotatably connected to the base frame 11 via the rotating shaft 135, and the upper end thereof is rotatably connected to the push block 136. A push groove 161 is formed on the lower side of the lifting plate 16, and the push block 136 is slidably set in the push groove 161.
[0024] Based on the above structure, the jacking plate 16 is plugged into the bottom of the cargo pallet, and then the jacking motor 151 is started, and the jacking screw 152 drives the screw nut 153. Under the constraint of the sliding structure of the base frame 11, the screw nut 153 pushes the lower end of the inner fork arm 132 to translate, so that the upper end of the outer fork arm 133 can move along the lower side of the jacking plate 16, thereby making the inner fork arm 132 and the outer fork arm 133 rotate relative to each other, and realizing the jacking operation. Such a truck fork assembly 10 is lifted by the scissor-fork action of the inner fork arm 132 and the outer fork arm 133. It has a simple structure, a large jacking stroke, and a lower plug-in position, which makes it more versatile. Such a structure is stable and compact. The jacking structure stably lifts the cargo being forked from below, and the lifting force at each lifted position is balanced, which makes the handling stability higher.
[0025] As a specific embodiment, guide grooves 111 are formed on the inner side surfaces of the side plates on both sides of the base frame 11, and sliders 14 are provided at the ends of the push shafts 134 on both sides of the screw nut 153. The sliders 14 are slidably arranged in the corresponding guide grooves 111. This can improve the smoothness of the movement of the screw nut 153, thereby improving the lifting stability of the lifting plate 16.
[0026] Furthermore, a support block 154 is provided on the bottom side of the screw nut. The support block 154 is arranged in contact with the bottom side of the base frame 11. This can transfer the downward radial load force exerted on the lifting screw 152 by the cargo supported by the lifting plate 16 to the support block 154, that is, to the base frame 11, thereby ensuring the structural stability of the lifting screw 152 and making the screw drive structure operate more smoothly. A plurality of recessed holes 1541 are formed on the bottom surface of the support block 154 for contacting the bottom side of the base frame 11. The recessed holes 1541 can reduce sliding friction, thereby reducing energy consumption.
[0027] As a specific embodiment, the chassis 11 is further provided with a drive wheel 17, a drive motor 18, and a reducer 19. The output end of the drive motor 18 is connected to the reducer 19, and the output end of the reducer 19 is connected to the drive wheel 17. In this way, the drive wheel 17 can be electrically driven to drive the connected chassis 11 to move forward and backward, thereby improving the convenience of forklift transportation.
[0028] Furthermore, the reducer 19 is a bevel gear reducer 19 capable of adjusting the torque direction of the drive motor 18. The reducer 19 has output shafts on its left and right sides, perpendicular to the motor shaft of the drive motor 18, along a first straight line. Both output shafts are connected to the drive wheels 17. The provision of two drive wheels 17 on the left and right improves the stability of the rolling support for the chassis 11.
[0029] As a specific embodiment, auxiliary wheels 20 are rotatably mounted on the chassis 11 to assist in rolling support of the chassis 11, thereby improving the stability of the chassis 11 during operation. Specifically, a mounting block is provided within the chassis 11, and auxiliary wheels 20 are rotatably connected to the left and right sides of the mounting block on a second straight line parallel to the first straight line. The two auxiliary wheels 20 are arranged in a front-to-rear correspondence with the two drive wheels 17, further improving the support stability of the chassis 11.
[0030] Furthermore, a swing shaft 22 is provided through the mounting block, which rotates in the front-to-back direction. Both ends of the swing shaft 22 are fixed to mounting seats within the chassis 11. This allows the two auxiliary wheels 20 to swing up and down via the swinging mounting block. When encountering an uneven floor, the two auxiliary wheels 20 can adjust up and down within a certain range to adapt to the uneven ground.
[0031] As a specific fact, one end of the hinge shaft 131 is relatively rotatably mounted with an anti-slip member 23, which is fixed to the outer side of the outer fork arm 133 by screws. In this way, the anti-slip member 23 can ensure the stability of the hinge structure of the inner fork arm 132 and the outer fork arm 133.
[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the scope of protection of the present invention.
