[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] There are trolleys with different functions in the factory to assist in operations such as object handling and prying. However, the trolleys in the factory are generally single-function and can only provide a single function. Therefore, in the factory where many different operations are required, multiple trolleys with different functions need to be set up, resulting in too many trolleys and occupying more space.

[0028] Example 1

[0029] The present application discloses a multifunctional lifting and transporting trolley 100, which at least includes the functions of carrying and prying objects, such as Figure 1-3 As shown, the lifting trolley 100 in one embodiment of the utility model includes a main frame 10, wheels 20, a plurality of load-bearing arms 30 and a lifting arm 40. The wheels 20 are rotatably connected to the main frame 10 to reduce resistance during movement and facilitate movement of the trolley. The plurality of load-bearing arms 30 are connected to the main frame, and they cooperate with each other to carry goods. The lifting arm 40 is connected to and can be stored in the main frame 10, and the lifting arm has a fixing portion for fixing a chain 50, and the chain 50 is used to connect the object to be lifted.

[0030] The lift trolley 100 includes a load-bearing arm 30, so it can provide an article carrying function. At the same time, the lift trolley 100 is provided with a lifting arm 40 for providing a fixed position for the prying chain 50, and the lifting arm 40 can be stored in the main frame 10, so the lift trolley 100 can switch between the two working modes of the carrying mode and the prying mode, and has high flexibility.

[0031] Specifically, the lifting arm 40 is pivotally connected to the main frame 10 , and can rotate toward one side of the carrying arms 30 and be supported on one of the carrying arms 30 . The carrying arm 30 supporting the lifting arm 40 is used to provide a fulcrum for the lifting arm 40 .

[0032] Furthermore, in order to improve the stability during the lifting operation, the lifting arm 40 can be set in the middle position of the lifting vehicle 100, which can avoid the situation that the lifting vehicle 100 is overturned when it is set at both sides. Specifically, the main frame 10 includes a cross bar 11, the wheels 20 are set at both ends of the cross bar 11, and the bearing arms 30 are distributed on the cross bar 11, including a first bearing arm 31 set at the middle position of the cross bar 11, and second bearing arms 32 distributed on both sides of the first bearing arm 31, and the lifting arm 40 is correspondingly set above the first bearing arm 31.

[0033] Preferably, a receiving groove 121 for receiving the lifting arm 41 is provided on the main frame 10 , and when the lifting arm 40 rotates in a direction away from the first supporting arm 31 , it can be at least partially received in the receiving groove 121 and fixed.

[0034] In one embodiment, the main frame 10 further includes a vertical rod 12 connected to the cross bar 11, and the vertical rod 12 is fixed at the middle position of the cross bar 11, that is, corresponding to the connection position of the first load-bearing arm 31. Therefore, the main frame 10 is a T-shaped structure, and the overall material is less, and the cost and weight are lower while ensuring the structural rigidity. The storage slot 121 is opened on the vertical rod 12, and the lifting arm 40 is pivotally connected to the vertical rod 12 at the same time.

[0035] In one embodiment, the lengths of all the carrying arms 30 can be set to be the same or different, preferably all the same. The length of the lifting arm 40 can be set to be greater than the lengths of all the carrying arms 30 .

[0036] When the lifting arm 40 is stored in the storage slot 121, a fixing structure needs to be added to the lifting arm 40 to prevent the lifting arm 40 from rotating in the direction of the first bearing arm 31 when moving. Preferably, a first hole 41 is opened on the lifting arm 40, and a second hole 122 is opened on the vertical rod 12 accordingly. When the lifting arm 40 is in the storage position, the first hole 41 and the second hole 122 are coaxial. At this time, the lifting arm 40 can be fixed by setting a fixing pin 13 in the two holes.

[0037] Of course, in other embodiments, the lifting arm 40 may be fixed to the vertical rod 12 by using buckles or straps, etc., which is not limited in this embodiment.

[0038] After the lifting arm 40 is rotatably supported on the first bearing arm 31 , the fixing pin 13 can be inserted into the first hole 41 . Since the fixing pin 13 does not move after being inserted into the first hole 41 , the fixing pin 13 inserted into the first hole 41 constitutes a fixing portion for fixing the chain 50 .

[0039] Preferably, a plurality of first holes 41 can be provided on the lifting arm 40, wherein a certain first hole 41 is coaxial with the second hole 122 when the lifting arm 40 is received in the receiving groove 121, so that the fixing pin 13 can be placed in different first holes 41 to provide a fixed position for the lifting chain 50. Such a setting can provide different lengths of force arms for the lifting trolley 100, with a wider range of choices and higher flexibility.

[0040] In one embodiment, a baffle 14 is further provided on the frame 10 , which is connected to the cross bar 11 and the vertical bar 12 , and is used to provide a barrier for the objects when they are being transported, so as to prevent the objects from falling off the frame 10 .

[0041] Preferably, the notch of the storage groove 121 is flush with the plane where the baffle 14 is located, and when the lifting arm 40 is in the storage position, it is completely stored in the storage groove 121. At this time, the baffle 14 and the vertical rod 12 form a flat plane on the front side without any protrusions, thereby preventing the items from tilting or even sliding off the frame 10.

[0042] The carrying arm 30 constitutes a platform for supporting items. In one embodiment, the length of the carrying arm 30 is adjustable, so that the area of ​​the item support platform is variable. When the volume of the items to be transported is small, the length of the carrying arm 30 can be appropriately shortened to adapt; and when the volume of the items to be transported is large, the length of the carrying arm 30 can be appropriately increased to adapt, which is highly flexible. Of course, the carrying arm 30 can also be set to a fixed length, which is not limited in this embodiment.

[0043] It is easy to imagine that the tops of all the carrying arms 30 are in the same plane, so that the goods supported by the carrying arms 30 will not shake or fall over, thereby improving the stability of the goods during transfer.

[0044] Here, the lifting trolley 100 in this embodiment is further explained in combination with specific usage scenarios.

[0045] When the goods need to be transported, the lifting arm 40 is stored in the storage slot 121 and fixed with the fixing pin 13. Figure 1 As shown; when lifting operation is required (such as Figure 3As shown in the lifting manhole cover, pull out the fixing pin 13, rotate the lifting arm 40 and support it on the first support arm 31, pass the fixing pin 13 through the chain 50 and fix it in the first hole 41 therein, use the wheel 20 as a fulcrum to press down the handrail 15 in the oblique downward direction to the rear, and use the lever to lift the object away.

[0046] Example 2

[0047] exist Figure 4 and 5 In the embodiment shown, the lifting trolley 100 abandons the lifting arm 40, and the first carrying arm 31 is designed to be retractable, which can be extended along its own length direction (other structures are the same as those in embodiment 1 and are not repeated here). When in the retracted state, the length of the first carrying arm 31 is the shortest and can be used for carrying items; when in the extended state, the first carrying arm 31 enters the lifting mode, and the lifting operation can be performed by fixing the lifting chain to the first carrying arm 31 at this time.

[0048] Similar to the lifting arm 40 , the first load-bearing arm 31 in this embodiment may have a plurality of holes at the far end, and the fixing pins 13 are inserted into the holes on the first load-bearing arm 31 to form a fixing portion for fixing the chain 50 .

[0049] Preferably, the extension length of the first bearing arm 31 can be adjusted. In this case, the length of the force arm provided by the first bearing arm 31 can also be adjusted, which can cope with more scenarios and has higher flexibility.
