Detailed Embodiments

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0017] Example 1. Please refer to Figure 1-4 The present utility model provides a technical solution: a tank trailer trolley, including a base 2; a lifting component is provided on the upper surface of the base 2, and an arc-shaped supporting portion is provided at the top of the lifting component for supporting the bottom of the tank 1; a through hole 21 penetrating the left and right ends is opened on the side wall of the base 2 for connecting the forklift forks; a pull ring 22 is fixedly connected to each of the left and right ends of the base 2, one end of a binding strap is tied to one pull ring 22, and the other end bypasses the top of the tank 1 and is tied to the other pull ring 22 for fixing the tank 1; a walking wheel 3 is detachably connected to each of the four corners at the lower end of the base 2 for the base 2 to be movable; at least a trailer hook 23 is connected to one of the side walls of the base 2 for driving the base 2 to move by connecting a trailer.

[0018] During use, take the tank 1 placed on the supporting wheel device in the background technology as an example; in the initial state, the walking wheels 3 are not installed on the base 2 to reduce the overall height. The forklift forks are inserted into the through holes 21 to place the base 2 at the bottom of the tank 1, and then lifted until the top of the lifting component supports the bottom of the tank 1, and at the same time the tank 1 leaves the supporting wheel device; then, the tank 1 is tied up with a binding strap so that the tank 1 and the base 2 are integrated to prevent the tank 1 from rolling over; then, after relying on the forklift to transfer the tank 1 away from the supporting wheel device station, the walking wheels 3 are installed one by one at the four corners of the base 2, and the base 2 is put down so that the walking wheels 3 support the ground. Then, the trailer is hooked to the trailer hook 23 to drag the tank 1 to move to the next station. At this time, not only is there no request for the overhead crane, but the forklift is also only a temporary handling device. When transferring the tank 1, the forklift can also be liberated and can work for another station. The equipment occupation is small, and the overall working efficiency of the workshop is improved.

[0019] An exemplary detachable connection method of the walking wheel 3. Threaded holes 24 are respectively opened at the four corners of the lower end of the base 2. An insertion shaft 32 is sleeved on the wheel shaft of the walking wheel 3. A threaded section 33 is provided at the upper end of the insertion shaft 32 for threaded connection in the threaded hole 24; on the insertion shaft 32, a limiting shoulder 34 is fixedly provided below the threaded section 33, and the limiting shoulder 34 abuts against the lower end surface of the base 2. It can be seen that the limiting shoulder 34 bears the main weight, avoiding the thread from bearing the weight and improving the bearing capacity. Among them, the lower end of the insertion shaft 32 is a sleeve portion sleeved on the wheel shaft, so that the wheel shaft can rotate, that is, the insertion shaft 32 does not move, while the wheel shaft is rotatable.

[0020] Exemplary lifting components, the lifting components include a pair of bottom plates 5, a pair of supports 51 are fixedly connected to the bottom plates 5, the top end of the support 51 is hinged to one of the corner parts of the triangular seat 52, and the other two corner parts of the triangular seat 52 are respectively rotatably connected with support rollers 53; the support rollers 53 abut against the bottom of the tank body 1, and are used for a plurality of the support rollers 53 to be distributed in an arc along the bottom of the tank body 1 to form the arc-shaped support part. In other words, the two groups of triangular seats 52 are symmetrically distributed before and after with the center of gravity of the tank body 1 as the reference, each group of two triangular seats 52 are symmetrically distributed left and right with the axis of the tank body 1 as the reference, each triangular seat 52 has two support rollers 53, and the four support rollers 53 are distributed along the bottom arc surface 41 of the tank body 1, and the connection line of the four support points forms an arc to constitute the arc-shaped support part. It can be seen that since the triangular seat 52 can swing, when the lifting base 2 is lifted, the four support rollers 53 can automatically find the support position.

[0021] A further optimization is that the bottom plate 5 is slidably connected to the base 2; a row of equally spaced pin holes 26 are provided on the upper surface of the base 2; a through hole 55 corresponding to the position of the pin holes 26 is provided in the middle of the bottom plate 5, and is used for fixing the position of the bottom plate 5 after inserting a pin through the through hole 55 and into the pin hole 26. As Figure 1 shown, by adjusting the distance between the two bottom plates 5, the tank body 1 with different diameters can be adapted, the versatility is improved, the cost is reduced, and it can be flexibly adjusted to adapt to the tank bodies 1 of different sizes, and it is suitable for the production needs of small batches and multiple batches. Among them, an exemplary sliding connection method is that a chute 25 is provided on the base 2, a convex block 54 is provided under the bottom plate 5, and the convex block 54 is inserted into the chute 25 to limit the linear translation of the bottom plate 5 to form a sliding connection.

[0022] Embodiment 2, please refer to Figure 5 ; This embodiment is based on Embodiment 1, the difference is that the lifting components are different, the lifting components are a pair of symmetrically arranged left and right support plates 4, the top end of each support plate 4 is set as an arc surface 41, and is used for forming the arc-shaped support part; the bottom end of the support plate 4 is detachably connected to the upper surface of the base 2. An exemplary detachable method is, for example, to install the support plate 4 on the base 2 through bolts.

[0023] Although the arc surface 41 of the support plate 4 is fixed, the cost of the support plate 4 itself is lower than that of the support roller 53. It is applicable to the mass production of the same type of tank body 1, and since the support plate 4 is detachable, even when the model of the tank body 1 is changed, the production needs can be met by replacing the support plate 4. Therefore, on the basis of having the advantages of Embodiment 1, the cost of this embodiment can be further reduced.

[0024] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
