It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model. Example

[0018] In one embodiment of this application, such as Figures 1-3 , Figures 5-7 as well as Figure 10 , Figure 12 As shown, this embodiment provides a lightweight tilting electric palletizing cart, including a tilting frame 7, a lifting slide rail 1, a moving component 2, a lifting frame 3, a lifting drive device 4, a limit clamp 5, and a clamp drive device 6.

[0019] like Figure 1 and Figure 10As shown, the lifting slide rail 1 is a single rail, and a first groove 11 is formed along its length. The inclined frame 7 is a rectangular frame, and the angle between the inclined surface of the inclined frame 7 and the horizontal plane is an acute angle, ranging from 50° to 80°; in this embodiment, 70° is selected. One end of the inclined frame 7 along its length is connected to the lifting slide rail 1, and the end of the inclined frame 7 connected to the lifting slide rail 1 is mounted on the moving component 2. The other end of the inclined frame 7 along its length is away from the lifting slide rail 1, forming an acute angle between the inclined frame 7 and the lifting slide rail 1, ranging from 10° to 50°. Several connecting support rods 71 ​​connect the inclined frame 7 and the lifting slide rail 1. The inclined frame 7 and the back of the lifting slide rail 1 are connected by a support rod 71, which ensures the support of the lifting slide rail 1 and improves the overall load-bearing strength of the palletizing vehicle. The inclined frame 7 is mainly designed to make it easier for operators to operate the palletizing vehicle at a more suitable height. The overall center of gravity of the vehicle is shifted to the rear, making it easier for operators to operate the palletizing vehicle by using their own weight as a counterweight, making the whole vehicle lighter and more flexible.

[0020] like Figures 1-3 As shown, the lifting frame 3 is a rectangular frame, slidably mounted on the lifting rail 1. The lifting frame 3 is equipped with forks 31 suitable for inserting into the bottom of goods. The width of the forks 31 is less than the width of the lifting frame 3, forming an angle between the forks 31 and the lifting frame 3; this angle is 90°-120°, and in this embodiment, 90° is chosen. Furthermore, the forks 31 are detachably connected to the lifting frame 3, allowing for the selection and replacement of forks 31 of different widths and lengths depending on the type of goods, thus improving the adaptability of the palletizing vehicle of this application. A first slider 33 is located at the center of the lifting frame 3 in the width direction. Two first sliders 33 are provided, located at opposite ends of the lifting frame 3 in the length direction, and slidably mounted within the first groove 11. The two first sliders 33 are upper and lower limited to ensure the stability of the lifting frame 3 during sliding and lifting, and also provide greater stability when connected to the chain 43.

[0021] like Figure 10 as well as Figure 12As shown, the lifting drive device 4 is mounted on the moving component 2. The power output of the lifting drive device 4 is connected to the lifting frame 3 to drive the lifting frame 3 to move up and down along the lifting slide rail 1. The lifting drive device 4 includes two sprockets 42 and a power box. The power box contains a battery and a geared motor. The two sprockets 42 are respectively rotatably mounted at the upper and lower ends of the lifting slide rail 1. The output shaft of the geared motor is coaxially connected to the lower sprocket 42 and drives the sprocket 42 to rotate. A chain 43 is connected between the two sprockets 42 and is wound around the two sprockets 42. The first slider 33 of the lifting frame 3 is fixedly connected to the chain 43. The chain 43 drives the lifting frame 3 to move up and down along the first slide groove 11. With the battery and geared motor, the lifting frame 3 is driven by pure electricity and moved up and down by the chain 43. The structure is simpler and lighter, the operating cost is low, and it can also get rid of the regional limitation of the power supply, making its application range wider.

[0022] like Figures 1-10 as well as Figure 12 As shown, the moving component 2 is located at the lower part of the lifting slide rail 1. The moving component 2 includes a mounting frame 21. Two moving wheels 22 are rotatably mounted on the lower part of the mounting frame 21 near the lifting slide rail 1. A caster wheel 23 is mounted on the end of the mounting frame 21 away from the lifting slide rail 1. The diameter of the moving wheels 22 is larger than the diameter of the caster wheel 23.

One end of the reinforcing support rod 24 is connected to the mounting frame 21, and the other end is connected to the upper part of the inclined frame 7. The caster wheel 23 facilitates the adjustment of the direction of the palletizing cart. Through the cooperation of the foot pedal 25 and the inclined frame 7, the entire cart does not require additional counterweight. The operator's foot on the foot pedal 25 becomes the counterweight, making the entire cart lighter and more flexible.

[0023] like Figures 5-7As shown, the limiting clamp 5 is slidably mounted on the lifting frame 3. The limiting clamp 5 is located at the end of the lifting frame 3 away from the fork plate 31. The limiting clamp 5 cooperates with the fork plate 31 to clamp the goods. The limiting clamp 5 includes a sliding plate 51, a clamping plate 52 and a limiting plate 53. The sliding plate 51 is slidably engaged with the lifting frame 3 and is connected to the power output part of the clamp driving device 6. The clamping plate 52 is connected to the sliding plate 51 and is arranged parallel to the fork plate 31. The limiting plate 53 is mounted on the clamping plate 52 and is used to limit the goods in a direction different from the clamping direction. The position of the limiting plate 53 in the horizontal direction is adjustable. There is one limiting plate 53, which is located at one end of the clamping plate 52 in the length direction. The limiting plate 53 is an angle steel plate. One inner side of the limiting plate 53 is in contact with the upper surface of the clamping plate 52. Several first connecting holes 54 are opened at the position where the limiting plate 53 is in contact with the clamping plate 52. Several second connecting holes 55 are opened at the corresponding positions where the clamping plate 52 is in contact with the limiting plate 53. The several second connecting holes 55 are arranged along the length direction of the clamping plate 52. The first connecting holes 54 are arranged in a row. The spacing between the first connecting holes 54 is the same as the spacing between the second connecting holes 55. The first connecting holes 54 and the second connecting holes 55 are connected by bolts provided inside them. The lifting frame 3 is a rectangular frame, and two limiting slide rods 32 are installed inside the lifting frame 3. The two limiting slide rods 32 are arranged parallel to the length direction of the lifting slide rail 1. The limiting slide rods 32 pass through the sliding plate 51, and the two ends of the limiting slide rods 32 are respectively connected to the opposite inner side of the lifting frame 3. Through the setting of multiple first connecting holes 54 and second connecting holes 55, the horizontal position of the limiting plate 53 can be adjusted by the connection and cooperation of different first connecting holes 54 and second connecting holes 55, thereby facilitating the adaptation of the limiting plate 53 to the size of the goods. A single limiting plate 53 limits and clamps the side of the goods from the horizontal direction, preventing them from slipping, saving the labor cost of manually supporting the goods.

[0024] like Figure 1As shown, a clamp driving device 6 is mounted on the lifting frame 3. The power output of the clamp driving device 6 is connected to the limiting clamp 5 and drives the limiting clamp 5 to slide on the lifting frame 3. In this embodiment, the clamp driving device 6 uses an electric push rod, model DT500-300, and its output end is connected to the sliding plate 51. Two handles 72 are provided at the end of the inclined frame 7 away from the moving component 2. The two handles 72 are respectively located on both sides of the inclined frame 7 and extend into two long rods. This arrangement facilitates the application of pressure more easily and makes it easier for workers to apply force to move the palletizing cart. The handles 72 are equipped with control switches 73 for controlling the opening and closing of the lifting drive device 4 and the clamp driving device 6. The control switches 73 include a general power switch, a first button switch for controlling the forward or reverse rotation of the reduction motor of the lifting drive device 4, and a second button switch for controlling the extension or retraction of the clamp driving device 6. The control switches 73 are conventional mechanical and electrical control switches, which are conventional technical means in this field, and their structure and principle will not be described in detail here.

[0028] like Figure 10 and Figure 12 As shown, the lifting drive device 4 is mounted on the moving component 2. The power output of the lifting drive device 4 is connected to the lifting frame 3 to drive the lifting frame 3 to move up and down along the lifting slide rail 1. The lifting drive device 4 includes two sprockets 42 and a power box. The power box contains a battery and a geared motor.

A chain 43 is connected between the two sprockets 42 in each set. The chain 43 is wound around the two sprockets 42. The power box 41 contains a battery and a double-headed geared motor. The internal structure of the power box 41 is relatively conventional and is not shown in the figure. It mainly houses the battery and the double-headed geared motor to form an electric drive system, which is a conventional technology that those skilled in the art can conceive of. The two output shafts of the dual-head geared motor are coaxially connected to two sprockets 42 located at the lower end of the second slide groove 12, driving the sprockets 42 to rotate. The second slider 34 of the lifting frame 3 is fixedly connected to the chain 43, and the chain 43 drives the lifting frame 3 to move up and down along the second slide groove 12. Through the bidirectional output of the dual-head geared motor, the transmission of the two sets of sprockets 42 is realized, and thus the two chains 43 drive the lifting frame 3 to run more smoothly through the two sets of second sliders 34.

[0037] like Figure 1 and Figure 11As shown, the moving component 2 is located at the lower part of the lifting slide rail 1. The moving component 2 includes a mounting frame 21. Two moving wheels 22 are rotatably mounted on the lower part of the mounting frame 21 near the lifting slide rail 1. A caster wheel 23 is mounted on the end of the mounting frame 21 away from the lifting slide rail 1. The diameter of the moving wheels 22 is larger than the diameter of the caster wheel 23. The moving wheels 22 play a major load-bearing role. A foot pedal 25 is mounted above the caster wheel 23 and is connected to the mounting frame 21. A reinforcing support rod 24 is mounted on the end of the mounting frame 21 away from the lifting slide rail 1. One end of the reinforcing support rod 24 is connected to the mounting frame 21, and the other end is connected to the upper part of the inclined frame 7. The caster wheel 23 facilitates the adjustment of the direction of the palletizing cart. Through the cooperation of the foot pedal 25 and the inclined frame 7, the entire cart does not require additional counterweight. The operator's foot on the foot pedal 25 becomes the counterweight, making the entire cart lighter and more flexible.

[0038] like Figures 5-7 As shown, the limiting clamp 5 is slidably mounted on the lifting frame 3. The limiting clamp 5 is located at the end of the lifting frame 3 away from the fork plate 31. The limiting clamp 5 cooperates with the fork plate 31 to clamp the goods. The limiting clamp 5 includes a sliding plate 51, a clamping plate 52 and a limiting plate 53. The sliding plate 51 is slidably engaged with the lifting frame 3 and is connected to the power output part of the clamp driving device 6. The clamping plate 52 is connected to the sliding plate 51 and is arranged parallel to the fork plate 31. The limiting plate 53 is mounted on the clamping plate 52 and is used to limit the goods in a direction different from the clamping direction. The position of the limiting plate 53 in the horizontal direction is adjustable. There is one limiting plate 53, which is located at one end of the clamping plate 52 in the length direction. The limiting plate 53 is an angle steel plate. One inner side of the limiting plate 53 is in contact with the upper surface of the clamping plate 52. Several first connecting holes 54 are opened at the position where the limiting plate 53 is in contact with the clamping plate 52. Several second connecting holes 55 are opened at the corresponding positions where the clamping plate 52 is in contact with the limiting plate 53. The several second connecting holes 55 are arranged along the length direction of the clamping plate 52. The first connecting holes 54 are arranged in a row. The spacing between the first connecting holes 54 is the same as the spacing between the second connecting holes 55. The first connecting holes 54 and the second connecting holes 55 are connected by bolts provided inside them. The lifting frame 3 is a rectangular frame, and two limiting slide rods 32 are installed inside the lifting frame 3. The two limiting slide rods 32 are arranged parallel to the length direction of the lifting slide rail 1. The limiting slide rods 32 pass through the sliding plate 51, and the two ends of the limiting slide rods 32 are respectively connected to the opposite inner side of the lifting frame 3. Through the setting of multiple first connecting holes 54 and second connecting holes 55, the horizontal position of the limiting plate 53 can be adjusted by the connection and cooperation of different first connecting holes 54 and second connecting holes 55, thereby facilitating the adaptation of the limiting plate 53 to the size of the goods. A single limiting plate 53 limits and clamps the side of the goods from the horizontal direction, preventing them from slipping, saving the labor cost of manually supporting the goods.

[0039] like Figure 1 As shown, a clamp driving device 6 is mounted on the lifting frame 3. The power output of the clamp driving device 6 is connected to the limiting clamp 5 and drives the limiting clamp 5 to slide on the lifting frame 3. In this embodiment, the clamp driving device 6 uses an electric push rod, model DT500-300, and its output end is connected to the sliding plate 51. Two handles 72 are provided at the end of the inclined frame 7 away from the moving component 2. The two handles 72 are respectively located on both sides of the inclined frame 7 and extend into two long rods. This arrangement facilitates the application of pressure more easily and makes it easier for workers to apply force to move the palletizing cart. The handles 72 are equipped with control switches 73 for controlling the opening and closing of the lifting drive device 4 and the clamp driving device 6. The control switches 73 include a general power switch, a first button switch for controlling the forward or reverse rotation of the reduction motor of the lifting drive device 4, and a second button switch for controlling the extension or retraction of the clamp driving device 6. The control switches 73 are conventional mechanical and electrical control switches, which are conventional technical means in this field, and their structure and principle will not be described in detail here.

[0041] like Figure 11 As shown, the lifting slide rail 1 is a cuboid frame, and two second slide grooves 12 are provided along its length, respectively located on both sides of the width direction of the lifting slide rail 1. The tilting frame 7 is a rectangular frame, and the angle between the tilting surface of the tilting frame 7 and the horizontal plane is an acute angle, ranging from 50° to 80°; in this embodiment, 70° is selected. One end of the tilting frame 7 along its length is connected to the lifting slide rail 1, and this end is mounted on the moving component 2. The other end of the tilting frame 7 along its length is away from the lifting slide rail 1, forming an acute angle between the tilting frame 7 and the lifting slide rail 1, ranging from 10° to 50°. Several connecting support rods 71 ​​connect the tilting frame 7 and the lifting slide rail 1. The inclined frame 7 and the lifting slide rail 1 are connected by a support rod 71, which ensures the support of the lifting slide rail 1 and improves the overall load-bearing strength of the palletizing vehicle. The inclined frame 7 is mainly designed to make it easier for operators to control the palletizing vehicle at a more suitable height. The overall center of gravity of the vehicle is shifted backward, making it easier for operators to control the palletizing vehicle by using their own weight as a counterweight, making the whole vehicle lighter and more flexible.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, the lifting frame 3 is a rectangular frame, slidably mounted on the lifting rail 1. The lifting frame 3 is equipped with fork plates 31 suitable for inserting into the bottom of goods. The width of the fork plates 31 is less than the width of the lifting frame 3, forming an angle between the fork plates 31 and the lifting frame 3; this angle is 90°-120°, and in this embodiment, 90° is chosen. Furthermore, the fork plates 31 are detachably connected to the lifting frame 3, allowing for the selection and replacement of fork plates 31 of different widths and lengths according to different types of goods, thus improving the adaptability of the palletizing vehicle of this application. The lifting frame 3 is equipped with two sets of second sliders 34, located on both sides of the width direction of the lifting frame 3. Each set of second sliders 34 is slidably connected to two second sliding grooves 12, with at least one slider in each set. The two sets of second sliders 34 provide horizontal limiting, making the vertical sliding of the lifting frame 3 more stable and smooth, increasing its load-bearing capacity, and extending its service life.

[0043] like Figure 11 , Figure 13 as well as Figure 4 As shown, the lifting drive device 4 is mounted on the moving component 2. The power output of the lifting drive device 4 is connected to the lifting frame 3 to drive the lifting frame 3 to move up and down along the lifting slide rail 1. The lifting drive device 4 includes a power box 41, two sprockets 42 and a chain 43. There are two sets of sprockets 42 and chains 43. The two sprockets 42 in each set are rotatably mounted at the upper and lower ends of the second slide groove 12 of the lifting slide rail 1. A chain 43 is connected between the two sprockets 42 in each set. The chain 43 is wound around the two sprockets 42. The power box 41 contains a battery and a double-headed geared motor. The internal structure of the power box 41 is relatively conventional and is not shown in the figure. It mainly houses the battery and the double-headed geared motor to form an electric drive system, which is a conventional technology that those skilled in the art can conceive of. The two output shafts of the dual-head geared motor are coaxially connected to two sprockets 42 located at the lower end of the second slide groove 12, driving the sprockets 42 to rotate. The second slider 34 of the lifting frame 3 is fixedly connected to the chain 43, and the chain 43 drives the lifting frame 3 to move up and down along the second slide groove 12. Through the bidirectional output of the dual-head geared motor, the transmission of the two sets of sprockets 42 is realized, and thus the two chains 43 drive the lifting frame 3 to run more smoothly through the two sets of second sliders 34.

[0044] like Figure 1 and Figure 11As shown, the movable component 2 is located at the lower part of the lifting slide rail 1; the movable component 2 includes a mounting frame 21, with two movable wheels 22 rotatably arranged at the lower part of the mounting frame 21 near the lifting slide rail 1, and a universal wheel 23 arranged at the end of the mounting frame 21 away from the lifting slide rail 1.

The limiting clamp 5 includes a sliding plate 51, a clamping plate 52 and a limiting plate 53. The sliding plate 51 is slidably engaged with the lifting frame 3 and is connected to the power output part of the clamp driving device 6. The clamping plate 52 is connected to the sliding plate 51 and is arranged parallel to the fork plate 31. The limiting plate 53 is mounted on the clamping plate 52 and is used to limit the goods in a direction different from the clamping direction. The horizontal position of the limiting plate 53 is adjustable. There are three limiting plates 53, which are respectively set at one end of the length direction and both sides of the width direction of the clamping plate 52. The limiting plates 53 are angle steel plates. The inner side of one of the three limiting plates 53 is in contact with the upper surface of the clamping plate 52. Several first connecting holes 54 are opened at the center of the part of the three limiting plates 53 that are in contact with the clamping plate 52. Several second connecting holes 55 are opened at the corresponding positions of the clamping plate 52 that are in contact with the three limiting plates 53. The limiting plates 53 on both sides of the clamping plate 52 are staggered. Only one second connecting hole 55 is provided on the clamping plate 52 corresponding to the two limiting plates 53 on both sides. A plurality of second connecting holes 55 on the limiting plate 53 at one end of the clamping plate 52 are arranged along the length direction of the clamping plate 52. First connecting holes 54 on the limiting plate 53 at one end of the clamping plate 52 are arranged in a row, with the spacing between the first connecting holes 54 on the limiting plate 53 being the same as the spacing between the corresponding second connecting holes 55 on the clamping plate 52. The first connecting holes 54 and second connecting holes 55 are connected by bolts installed inside them. The lifting frame 3 is a rectangular frame, and two limiting slide rods 32 are installed inside the lifting frame 3. The two limiting slide rods 32 are arranged parallel to the length direction of the lifting slide rail 1, and pass through the sliding plate 51. The two ends of the limiting slide rods 32 are respectively connected to the opposite inner surfaces of the lifting frame 3. Through the arrangement of multiple first connecting holes 54 and second connecting holes 55, and through the connection and cooperation of different first connecting holes 54 and second connecting holes 55, the horizontal position of the limiting plate 53 can be adjusted, thereby facilitating the adaptation of the limiting plate 53 to the size of the goods. Three limiting plates 53 limit and clamp the side of the goods from three horizontal directions to prevent them from slipping, making them more secure and saving the labor cost of manually supporting the goods.

[0046] The aforementioned limiting plate 53 is made of angle steel, and the method of adjusting the position of the limiting plate 53 by cooperating with the first connecting hole 54 and the second connecting hole 55 is only one embodiment of this application.

These will not be described in detail here.

[0047] A clamp drive device 6 is mounted on the lifting frame 3.

These handles 72 are respectively located on both sides of the inclined frame 7 and extend into two long rods. This arrangement facilitates easier application of pressure and allows workers to apply force to move the palletizing cart. Control switches 73 are provided on the handles 72 to control the opening and closing of the lifting drive device 4 and the clamp drive device 6.

[0048] In another embodiment of this application, the difference between this embodiment and other embodiments is that both the lifting drive device 4 and the clamp drive device 6 are pneumatic devices. The clamp drive device 6 uses a pneumatic linear actuator, specifically an HFB type pneumatic-hydraulic actuator. The lifting drive device 4 uses a linear cylinder, specifically an SA40*85M16 type. A chain 43 is fixedly connected to the output shaft end of the linear cylinder. A sprocket 42 is rotatably mounted on the upper end of the lifting slide rail 1. The chain 43 passes around the sprocket and is fixedly connected to the lifting frame 3, thereby realizing the up-and-down drive of the lifting frame 3.
