Description

Technical Field

[0001] This utility model relates to the technical field of logistics and warehousing equipment, and more precisely to a telescopic fork that can be raised and lowered. Background Technology

[0002] With the continuous development of the logistics industry, the volume of freight and warehouse goods is constantly increasing. To meet warehousing demands, the adoption rate of automated storage and retrieval systems (AS / RS) is gradually increasing. AS / RS can increase storage capacity by adding vertical storage space within the same area, and can achieve efficient retrieval and placement of goods through automated systems. Adopting AS / RS helps shorten logistics time, save logistics costs, and improve logistics efficiency. However, AS / RS and other new types of warehousing have high storage density, smaller space for goods retrieval and placement, and increasingly complex operating environments. Existing telescopic forks are insufficient to meet the diverse needs of confined spaces and complex operating environments.

[0003] Existing telescopic forks only have the function of forward and backward extension. Vertical movement relies on the relevant structure of the stacker crane to complete. The vertical movement range is generally large and the accuracy is poor. The relevant drive structure is also large in size, making it difficult to operate in narrow spaces, difficult to control accurately, and difficult to handle non-standard sized goods.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] like Figure 2 The diagram shown is a structural schematic of the lifting adjustment component of a telescopic fork that can be raised and lowered according to this application. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this application discloses an adjustable telescopic fork comprising two lifting components 1, a lifting drive motor 2, a roller chain 3, and a telescopic fork assembly 4. The lifting drive motor 2 is driven by one of the lifting components 1, and the two lifting components 1 are driven by the roller chain 3. The telescopic fork assembly 4 is mounted on top of the two lifting components 1. The lifting drive motor 2 drives one lifting component 1 to extend and retract vertically, and the other lifting component 1 is driven to extend and retract synchronously vertically, driving the telescopic fork assembly 4 to move vertically and horizontally, thus realizing the lifting adjustment function. The telescopic fork assembly 4 itself has a horizontal extension function. The adjustable telescopic fork can adjust its height and has a telescopic function, which can meet the needs of use in more different scenarios; the adjustable telescopic fork is more convenient and precise to operate.

[0022] The telescopic fork assembly 4 includes a base plate 40, and the bottom of the base plate 40 has a connecting plate 401 that is connected to the lifting assembly 1. The connecting plate 401 and the lifting assembly 1 are fixedly connected by bolts.

[0023] Specifically, the lifting assembly 1 includes a lifting base 10, a lifting bracket 11, a drive assembly 12, and a driven assembly 13. The lifting bracket 11 is slidably mounted on top of the lifting base 10, and the telescopic fork assembly 4 is mounted on top of the lifting bracket 11. The drive assembly 12 is connected to the lifting base 10, and the driven assembly 13 is connected to the lifting bracket 11. The drive assembly 12 and the driven assembly 13 are connected by a transmission. The drive assembly 12 is driven by the lifting drive motor 2 or the roller chain 3, which pushes the driven assembly 13 to raise or lower the lifting bracket 11, thereby raising or lowering the telescopic fork assembly 4.

[0024] The lifting base 10 is a U-shaped base, and the two side plates of the lifting base 10 have grooves 100 with the openings of the grooves 100 facing upwards. The lifting bracket 11 is slidably inserted into the two grooves 100. Preferably, the two side walls of the grooves 100 have slide rails 101, and the lifting bracket 11 has a slider 111 that can be slidably inserted into the slide rails 101. By combining the slide rails 101 and the slider 111, the sliding stroke and direction of the lifting bracket 11 are limited, preventing slippage and ensuring pointing accuracy.

[0025] The drive assembly 12 includes a drive shaft 120 rotatably connected to the lifting base 10. A drive eccentric gear 121 is fixedly mounted on the drive shaft 120. One end of the drive shaft 120 extends out of the lifting base 10, and a sprocket 14 is mounted on the end of the drive shaft 120 extending out of the lifting base 10 or is connected to the lifting drive motor 2. Roller chains 3 are wound around the two sprockets 14. The driven assembly 13 includes a driven shaft, which is rotatably connected to the lifting bracket 11. A driven eccentric gear 131 is fixedly mounted on the driven shaft, and the driven eccentric gear 131 meshes with the drive eccentric gear 121. When the two eccentric gears rotate, they drive the lifting bracket 11 to move up and down.

[0026] Furthermore, the drive shaft 120 is connected to the lifting base 10 via a bearing 1201. The bearing 1201 is fixedly connected to the lifting base 10, and the drive shaft 120 is rotatably inserted into the bearing 1201. By setting the bearing 1201, the smoothness of the rotation of the drive shaft 120 can be ensured, while extending its service life. Shaft end caps 1301 are respectively provided at both ends of the driven shaft to protect the driven shaft.

[0027] A concave wheel 122 is preferably fixedly installed on the drive shaft 120, and a cam 132 is fixedly installed on the driven shaft. The concave wheel 122 and the cam 132 engage to limit the movement.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
