[0032] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0033] like Figure 1-Figure 10 As shown, the cargo transport device of the utility model comprises:

[0034] A traveling assembly 1, the traveling assembly 1 comprises a frame 11, wheels 12 and a driving unit 13, the driving unit 13 and the wheels 12 are both arranged on the frame 11, and the driving unit 13 drives the wheels 12 to rotate around their own axis;

[0035] The load-bearing frame 2 is fixed on the upper part of the vehicle frame 11, and the load-bearing frame 2 has a load-bearing surface for carrying goods and shelves;

[0036] The surrounding frame 3 rotates around the width direction of the bearing surface at the end of the carrier frame 2, and the two end positions of the rotation path are respectively the surrounding position and the loading and unloading position. In the surrounding position, the surrounding frame 3 and the carrier frame 2 are enclosed to form an enclosure cavity with an open top. In the loading and unloading position, the surrounding frame 3 is used for the transportation of goods and shelves;

[0037] The locking assembly 4 is used to lock the surrounding frame 3 on the supporting frame 2 .

[0038] When the cargo transport device is in use, the driving unit 13 drives the wheels 12 to rotate so as to realize the movement of the frame 11 on the ground. In the initial state of the device, the surrounding frame 3 is in the surrounding position, and the surrounding frame 3 is locked in position by the locking component 4; after the device travels to the location of the cargo and the shelf through the driving unit 13 and the wheels 12, the locking operation of the surrounding frame 3 by the locking component 4 is removed, and the surrounding frame 3 is rotated to the loading and unloading position, so that one end of the surrounding frame 3 contacts the ground, and the surrounding frame 3 forms a slope for the cargo shelf to be transported from the ground to the supporting frame 2 through the slope, and then the surrounding frame 3 is rotated to the surrounding position, so that the surrounding frame 3 and the supporting frame 2 are enclosed to form an enclosed cavity and the cargo shelf is located in the enclosed cavity at this time, thereby preventing the cargo shelf from escaping from the enclosed cavity during transportation.

[0039] Then the device moves to the unloading position, removes the lock of the surrounding frame 3 by the locking assembly 4, and rotates the surrounding frame 3 to the loading and unloading position. The rotated surrounding frame 3 facilitates the passage of the cargo rack on the supporting frame 2 and moves it to the ground, thereby completing the unloading operation.

[0040] Therefore, in the above-mentioned cargo transportation device, the surrounding frame 3 can adjust its own position. At the loading and unloading position, it can form a slope between the ground and the supporting frame 2 to facilitate the loading and unloading of goods. At the surrounding position, it can form an surrounding cavity by enclosing itself and the supporting frame 2 to protect the safe transportation of the cargo shelf. Therefore, the operation is convenient and labor-saving, and it is easy to use.

[0041] The specific structure of the travel component 1 of the utility model is as follows Figure 5 and Figure 6As shown, in the traveling assembly 1, the projection of the frame 11 on the horizontal plane is rectangular as a whole, and two pairs of wheels 12 are provided, which are arranged on both sides of the frame 11. Each pair of wheels 12 includes a front wheel and a rear wheel, and the front wheel and the rear wheel rotate around their own axis at the end position of the frame 11. Two driving units 13 are provided, which are connected to the two pairs of wheels 12 in a one-to-one correspondence. The two pairs of wheels 12 are driven to rotate by the two driving units 13 respectively. When the rotation speeds of the two pairs of wheels 12 are consistent, the frame 11 keeps moving forward, and when the rotation speeds of the two pairs of wheels 12 are inconsistent, the frame 11 turns; because the two pairs of wheels 12 are driven to rotate by two independent driving units 13, the two pairs of wheels 12 can have a large rotation speed difference, and can rotate at different speeds in different directions, thereby realizing a sharp turn of the device, reducing the turning radius, thereby reducing the requirements for the use of the site, and improving the turning efficiency.

[0042] Specifically, the drive unit 13 includes a motor 131, a driving wheel 132, a driven wheel 133 and a crawler 134. The housing of the motor 131 is fixed to the frame 11, the output shaft is fixedly connected to the driving wheel 132, the driving wheel 132 is fixedly connected to the front wheel coaxially, and the driving wheel 132 is transmission-connected to the driven wheel 133 through the crawler 134, and the driven wheel 133 is fixedly connected to the rear wheel coaxially. In this way, after the motor 131 is started, it drives the driving wheel 132 to rotate, and the driving wheel 132 acts on the driven wheel 133 through the crawler 134, so that the driven wheel 133 rotates. Since the driving wheel 132 and the driven wheel 133 are respectively fixedly connected to the front wheel and the rear wheel coaxially, the front wheel and the rear wheel rotate at the same time, realizing the driving function of the device.

[0043] A further improvement is that two surrounding frames 3 are provided, which are arranged at both ends of the carrier frame 2. After adopting this structure, the surrounding frame 3 can be operated from any one of the front and rear ends of the carrier frame 2 to adjust the surrounding frame 3 to the surrounding position or the loading and unloading position, making the loading and unloading operation of the cargo rack more convenient.

[0044] A further improvement is that the surrounding frame 3 includes a rotating frame 31 and a guide side frame 32 . The rotating frame 31 is rotatably connected to the supporting frame 2 and has the same width direction. The guide side frames 32 are arranged on both sides of the rotating frame 31 .

[0045] After adopting this structure, two guide side frames 32 are provided and fixed to both sides of the rotating frame 31 respectively, so that the rotating frame 31 and the two guide side frames 32 form a limit groove to guide the direction of the cargo rack when loading and unloading the cargo rack to avoid deviation. Figure 7-10As shown, the carrier frame 2 includes a horizontal base frame 23 and a bottom frame 24 fixed on the base frame 23. The base frame 23 is fixed directly above the vehicle frame 11. The four corners of the bottom frame 24 are provided with convex shafts 22. The axis of the convex shaft 22 is parallel to the width direction of the vehicle frame 11. The rotating frame 31 is provided with sleeve holes 311 on both sides of the end adjacent to the bottom frame 24. The sleeve holes 311 are adapted to the convex shaft 22, so that the rotating frame 31 can rotate around the axis of the convex shaft 22, thereby realizing the rotation connection between the surrounding frame 3 and the carrier frame 2. The guide side frame 32 is fixed on the rotating frame 31. The plane where the guide side frame 32 is located is perpendicular to the plane where the rotating frame 31 is located. When loading and unloading goods, the guide side frame 32 can guide the loading and unloading direction of the cargo shelf. When the surrounding frame 3 moves to the surrounding position, the guide side frame 32 and the rotating frame 31 are both in the following positions. Figure 1 and Figure 2 The plumb direction shown can surround the cargo shelves on the carrier frame 2 from four sides, intercept and limit them, and prevent the cargo shelves from falling during transportation, thus achieving safe transportation.

[0046] A further improvement is that the locking assembly 4 includes a fixed locking sleeve 41, a movable locking sleeve 42 and a locking pin 43. The fixed locking sleeve 41 and the movable locking sleeve 42 are respectively connected to the carrier frame 2 and the surrounding frame 3, and the movable locking sleeve 42 is plugged into and matched with the fixed locking sleeve 41 through the locking pin 43; when the carrier frame 2 and the surrounding frame 3 are locked and connected through the locking assembly 4, the coaxial centerline of the movable locking sleeve 42 is located above the fixed locking sleeve 41.

[0047] Specifically, the fixed locking sleeve 41 extends in the vertical direction, the fixed locking sleeve 41 is fixed to the outside of the bottom frame 23 and the bottom frame 24, and the movable locking sleeve 42 is fixed to the guide side frame 32. After adopting the above improvement, when the surrounding frame 3 rotates to the surrounding position, the coaxial centerline of the movable locking sleeve 42 is located directly above the fixed locking sleeve 41, and the locking pin 43 is inserted into the inner side of the movable locking sleeve 42 and the fixed locking sleeve 41, which can prevent the surrounding frame 3 from rotating and realize the locking of the position of the surrounding frame 3. The locking pin 43 relies on its own gravity to penetrate the inner side of the fixed locking sleeve 41 and the movable locking sleeve 42. A limiting boss is provided at one end of the locking pin 43 adjacent to the movable locking sleeve 42, and the outer diameter of the limiting boss is larger than the inner diameter of the movable locking sleeve 42. In this way, while realizing the locking connection between the fixed locking sleeve 41 and the movable locking sleeve 42, the locking pin 43 is prevented from being separated from the fixed locking sleeve 41 and the movable locking sleeve 42.

[0048] A further improvement is that the inner diameter of the fixed lock sleeve 41 is larger than the inner diameter of the movable lock sleeve 42, and the lock pin 43 includes a first plug-in portion 431 adapted to the fixed lock sleeve 41 and a second plug-in portion 432 adapted to the movable lock sleeve 42. In this way, the outer diameter of the first plug-in portion 431 is larger than the inner diameter of the movable lock sleeve 42, that is, the first plug-in portion 431 cannot pass through the movable lock sleeve 42, thereby achieving a limited connection between the lock pin 43 and the movable lock sleeve 42, and preventing the lock pin 43 from being disengaged. Specifically, as Fig. 9 and Fig.10 As shown, the first plug-in portion 431 and the second plug-in portion 432 are threadedly connected, the first plug-in portion 431 is a threaded sleeve, one end of which is closed, and the closed end is hemispherical, which is convenient for inserting and fixing the lock sleeve 41, and the second plug-in portion 432 is a bolt. In this way, the first plug-in portion 431 and the second plug-in portion 432 are conveniently threadedly connected to form a lock pin 43, thereby completing the assembly operation of the locking assembly 4.

[0049] A further improvement is that closely distributed support rollers 5 are provided on the support frame 2 and / or the rotating frame 31, and the support rollers 5 rotate around their own axis and the distribution direction is parallel to the length direction of the support frame 2 and / or the rotating frame 31 where they are located.

[0050] Specifically, Figure 7 and Fig. 9 As shown, closely distributed supporting rollers 5 are provided on the bottom frame 24 and the rotating frame 31, wherein the supporting rollers 5 on the carrier frame 2 are distributed along the length direction of the bottom frame 24, and the supporting rollers 5 on the rotating frame 31 are distributed along the length direction of the rotating frame 31. In this way, during the process of loading and unloading the cargo rack, the supporting rollers 5 rotating around their own axis can reduce the friction force during loading and unloading, making transportation more convenient and labor-saving.

[0051] A further improvement is that a support member 21 is further provided on the carrier frame 2 , and when the surrounding frame 3 rotates to the surrounding position, the top of the support member 21 abuts against the guide side frame 32 .

[0052] Specifically, the support member 21 is fixed just above the bottom frame 24, and there are four support members 21, which are arranged two by two on both sides of the bottom frame 24. The support members 21 can limit the rotation range of the surrounding frame 3, so that when the support member 21 abuts against the guide side frame 32, the surrounding frame 3 is located in the surrounding position, and the movable locking sleeve 42 is aligned with the fixed locking sleeve 41, which facilitates the insertion of the locking pin 43 for locking.

[0053] A further improvement is that the support member 21 is magnetically matched with the guide side frame 32. Specifically, the support member 21 is a magnet, and the guide side frame 32 is an iron frame. In this way, when the surrounding frame 3 rotates to the supporting position, the support member 21 can not only position the surrounding frame 3 to ensure that the movable locking sleeve 42 is aligned with the fixed locking sleeve 41, but also attract the guide side frame 32 through the magnetic field force, thereby playing a role in initially fixing the guide side frame 32.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
