Description

Technical Field

[0001] This utility model relates to the technical field of material handling equipment, and specifically to a high-level picking vehicle. Background Technology

[0002] High-bay picking is a specialized piece of equipment used in warehousing and logistics. It is mainly used for picking goods on high-rise shelves. With the rapid development of e-commerce and the continuous upgrading of the logistics industry, high-bay picking plays an increasingly important role in modern warehouse management.

[0003] However, existing high-bay picking vehicles still have some technical problems. First, the pallet size of existing picking vehicles is usually fixed, which can only accommodate goods of the corresponding size or small size, resulting in poor adaptability. When it is necessary to pick goods of different sizes, especially large goods that exceed the standard pallet size, existing picking vehicles are difficult to meet the needs, leading to reduced picking efficiency and even the need to replace them with picking vehicles of different specifications.

[0004] Secondly, during high-altitude operations, operators often forget to bring necessary tools. Because existing picking carts lack suitable tool storage areas, operators need to lower the platform to retrieve tools and then raise it again, a process that is not only cumbersome but also significantly reduces work efficiency. Especially in busy warehouse environments, this unnecessary up-and-down movement wastes time and impacts overall picking efficiency. Utility Model Content

[0005] This utility model addresses the aforementioned problems and aims to provide a high-level picking cart. Through the separate design of the pallet body and the supporting base plate, the overall size of the pallet can be adjusted to accommodate goods of different sizes. Furthermore, tools can be fixed on the mast via magnetic attraction, making operation more convenient.

[0006] To achieve the above objectives, this utility model provides a high-level picking cart, comprising:

[0007] A chassis mechanism, comprising a chassis, a drive wheel assembly disposed at the bottom of the chassis, and a mast disposed vertically on the chassis;

[0008] The operating mechanism includes an operating platform that can be lifted and lowered on the first side of the gantry;

[0009] A pallet mechanism, comprising a pallet that can be lifted and lowered on the second side of the gantry;

[0010] The pallet includes a supporting base plate and a pallet body. The pallet body is slidably disposed on the supporting base plate, and the pallet body has a first position retracted on the supporting base plate and a second position extended outside the supporting base plate.

[0011] According to the above-described high-level picking vehicle, the support base plate is provided with first guide grooves arranged along the front-rear direction of the base frame on both sides, and the pallet body is provided with guide blocks arranged along the front-rear direction of the base frame on both sides, and the two guide blocks are slidably arranged in the two first guide grooves.

[0012] According to the above-described high-level picking vehicle, both sides of the supporting base plate are provided with L-shaped positioning plates, and the positioning plates and the supporting base plate together form the first guide groove, with the openings of the two first guide grooves facing each other.

[0013] According to the above-described high-level picking vehicle, one side of the positioning plate is designated as the positioning side, and the positioning side is provided with a first positioning hole and a second positioning hole arranged along the front and rear direction of the base frame. The guide block is provided with a first positioning pin corresponding to the first positioning hole or the second positioning hole. When the pallet body is in the second position, the first positioning pin can be inserted into the second positioning hole.

[0014] According to the above-described high-level picking vehicle, a second positioning pin is provided at the rear of the supporting base plate, and a third positioning hole is provided at the rear of the pallet body. When the pallet body is in the first position, the second positioning pin can be inserted into the third positioning hole.

[0015] According to the above-described high-level picking vehicle, the front end of the guide block is provided with an unlocking block, which is configured to be pressed down to drive the rear of the pallet body upward, so that the pallet body disengages from the second positioning pin.

[0016] According to the above-described high-level picking vehicle, the pallet mechanism further includes a first lifting cylinder, and the two sides of the gantry are provided with second guide grooves arranged in a vertical direction. The two opposite sides of the support base plate are provided with connecting arms. One end of the connecting arm is connected to the support base plate, and the other end of the connecting arm is connected to the second guide groove through a first guide wheel. The first lifting cylinder is arranged in a vertical direction on the base frame, and the piston rod of the first lifting cylinder is connected to the support base plate.

[0017] According to the above-described high-level picking vehicle, the two sides of the operating platform are connected to the second guide groove through the second guide wheels, and the top of the gantry is provided with a control area.

Detailed Implementation

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figure 1-3 As shown, a high-level picking vehicle includes a frame mechanism 100, an operating mechanism 200, and a pallet mechanism 300.

[0033] The frame mechanism 100 includes a base frame 110, a drive wheel assembly 120 arranged at the bottom of the base frame 110, and a mast 130 arranged vertically on the base frame 110. The base frame 110 is made of steel and has sufficient strength to support the weight of the entire high-level picking cart. The drive wheel assembly 120 includes four wheels, which are arranged at the four corners of the base frame 110. One or two wheels are designated as drive wheels, and the other wheels are designated as driven wheels. The drive wheels are connected to a motor, which drives the entire high-level picking cart to move through the rotation of the motor. The mast 130 is made of high-strength aluminum alloy and is fixed vertically on the base frame 110. The mast 130 is approximately 3 meters high, which can meet the needs of high-level picking.

[0034] The operating mechanism 200 includes an operating platform 210 that can be raised and lowered and is installed on the first side of the gantry 130. The operating platform 210 is provided with anti-slip texture and can accommodate one or two operators to stand and operate. The operating platform 210 can move up and down along the gantry 130 to adapt to picking needs at different heights.

[0035] The pallet mechanism 300 includes a pallet that can be lifted and lowered and is mounted on the second side of the gantry 130. The pallet includes a supporting base plate 310 and a pallet body 320. The pallet body 320 is slidably mounted on the supporting base plate 310. The pallet body 320 has a first position retracted on the supporting base plate 310 and a second position extended outside the supporting base plate 310. When the pallet body 320 is in the first position, the overall volume of the pallet is small, which facilitates the movement of the high-level picking cart in narrow aisles and is suitable for small-sized goods. When the pallet body 320 is in the second position, the area of ​​the pallet increases, which can hold larger-sized goods and more goods. Of course, it needs to be used in a relatively spacious place. Therefore, in this embodiment, the pallet can be used for goods of different sizes and different sites, and has good overall applicability.

[0036] In this embodiment, the support base plate 310 is made of high-strength steel, which has sufficient strength to support the weight of the goods, and the pallet body 320 is made of lightweight high-strength material, which is lightweight but has a strong load-bearing capacity.

[0037] Furthermore, in order to achieve stable adjustment of the pallet body 320, the support base plate 310 is provided with first guide grooves 311 arranged along the front and rear direction of the base frame 110 on both sides, and guide blocks 321 arranged along the front and rear direction of the base frame 110 on both sides of the pallet body 320. The two guide blocks 321 are slidably arranged in the two first guide grooves 311. When the guide blocks 321 are located in the first guide grooves 311, the outer sides of the two guide blocks 321 can respectively abut against the side walls of the two first guide grooves 311 to achieve horizontal limitation of the pallet body 320. Through the cooperation of the first guide grooves 311 and the guide blocks 321, the pallet body 320 can slide smoothly on the support base plate 310 without shaking or falling off.

[0038] Furthermore, both sides of the support base plate 310 are provided with L-shaped positioning plates 312. The positioning plates 312 and the support base plate 310 together form a first guide groove 311. The openings of the two first guide grooves 311 face each other, which can restrict the lateral movement of the pallet body 320. In this embodiment, the height of the guide block 321 is lower than the height of the first guide groove 311, so that the pallet body 320 has a certain displacement space in the vertical direction. However, at the same time, the positioning plates 312 can provide a limit for the pallet body 320 to prevent it from rising excessively and detaching from the support base plate 310.

[0039] Furthermore, one side of the positioning plate 312 is designated as a positioning side 312a. The positioning side 312a has a first positioning hole 312b and a second positioning hole 312c arranged along the front-rear direction of the base frame 110. The guide block 321 has a first positioning pin 321a corresponding to either the first positioning hole 312b or the second positioning hole 312c. The first positioning hole 312b is located at the rear of the positioning side 312a, and the second positioning hole 312c is located at the front of the positioning side 312a. Multiple first positioning holes 312b and multiple second positioning holes 312c are provided on the guide block 321. Multiple first positioning pins 321a are provided. When the pallet body 320 is in the first position, the multiple first positioning pins 321a can be inserted into multiple first positioning holes 312b respectively to lock the pallet body 320 in the retracted position. When the pallet body 320 is in the second position, the multiple first positioning pins 321a can be inserted into multiple second positioning holes 312c to lock the pallet body 320 in the unfolded position, ensuring the stability of the pallet body 320. At the same time, the first positioning pins 321a can be pulled out to unlock and facilitate the displacement of the pallet body 320.

[0040] Furthermore, a second positioning pin 313 is provided vertically at the tail of the support base plate 310, and a third positioning hole is provided at the tail of the pallet body 320. When the pallet body 320 is in the first position, the second positioning pin 313 can be inserted into the third positioning hole. Through the cooperation of the second positioning pin 313 and the third positioning hole, the pallet body 320 can be locked in the retracted position.

[0041] Furthermore, the front end of the guide block 321 is provided with an unlocking block 321b. The unlocking block 321b is configured to be pressed down to drive the tail of the tray body 320 upward, so that the tray body 320 disengages from the second positioning pin 313. When the tray body 320 is in the first position, part of the front end of the tray body 320 will also extend out of the outside of the support base plate 310, while the bottom of the unlocking block 321b is suspended. When the unlocking block 321b is pressed down, it can drive the front end of the tray body 320 downward, thereby causing the tail of the tray body 320 to tilt slightly upward, so that the third positioning hole disengages from the second positioning pin 313, thereby releasing the locked state and facilitating the movement of the tray body 320.

[0042] Furthermore, the pallet mechanism 300 also includes a first lifting cylinder 330. The gantry 130 has second guide grooves 131 arranged vertically on both sides. The supporting base plate 310 has connecting arms 314 on opposite sides. One end of the connecting arm 314 is connected to the supporting base plate 310, and the other end of the connecting arm 314 is connected to the second guide groove 131 via a first guide wheel. The first lifting cylinder 330 is arranged vertically on the base frame 110. The piston rod of the first lifting cylinder 330 is connected to the supporting base plate 310. The first lifting cylinder 330 can drive the supporting base plate 310 to move up and down, thereby driving the entire pallet mechanism 300 to rise or fall, achieving independent lifting of the pallet mechanism 300 and simplifying operation.

[0043] Furthermore, the two sides of the operating platform 210 are connected to the second guide groove 131 via second guide wheels. The top of the gantry 130 is provided with a control area, which is equipped with a first lifting switch 132 for controlling the lifting of the operating platform 210 and a second lifting switch 133 for controlling the lifting of the support base plate 310. Both the first lifting switch 132 and the second lifting switch 133 are push-button switches, which control the lifting of the operating platform 210 and the support base plate 310 respectively, so as to realize the independent lifting of the two.

[0044] Furthermore, the top of the gantry 130 is also provided with a magnetic area 134, which is located on one side of the control area and is used to place tools. The magnetic area 134 is made of a strong magnet and has an area of ​​about 30 square centimeters. It can attract metal tools such as wrenches and screwdrivers, making it convenient for operators to use. There is no need to carry tools with them, and it can also avoid the inconvenience caused by forgetting to bring tools.

[0045] Furthermore, the operating platform 210 is equipped with a rotatable guardrail 211. When the operating platform 210 is detached from the base frame 110, the guardrail 211 can be locked onto the operating platform 210. The guardrail 211 can be rotated to fold up or unfold, thereby switching its usage state. When the operating platform 210 is raised to a certain height, the guardrail 211 will automatically lock to ensure the safety of the operator.

[0046] In use, the operator stands on the operating platform 210 and controls the platform 210 to rise to an appropriate height via the first lifting switch 132, and then controls the tray to rise to an appropriate height via the second lifting switch 133. When the tray area needs to be increased, the operator can press down the unlocking block 321b to disengage the tray body 320 from the second positioning pin 313, and then pull the tray body 320 outward until the first positioning pin 321a is inserted into the second positioning hole 312c, locking the tray body 320 in the unfolded position. When the tray area needs to be reduced, the operator can pull the first positioning pin 321a out of the second positioning hole 312c, and then push the tray body 320 inward until the second positioning pin 313 is inserted into the third positioning hole, locking the tray body 320 in the retracted position.
