[0036] In view of the technical problem that the storage tank 1 is currently generally lifted by a crane or a crane during transportation, and the lifting equipment used in this transportation method is large and has poor maneuverability, low transportation efficiency, and high cost, this embodiment provides a tank transportation accessory that is used in conjunction with a forklift to achieve efficient transportation of the storage tank 1, improve the transportation maneuverability of the storage tank 1, and reduce the transportation cost of the storage tank 1.

[0037] The tank handling attachment of this embodiment is applied to a forklift to carry a tank 1. The forklift includes a forklift mast 3, and the bottom of the tank 1 has a support frame 2. Figure 1-Figure 4The tank handling attachment of this embodiment includes a connecting mechanism 4, a bottom supporting mechanism 5 and a top protecting mechanism 6.

[0038] In this embodiment, the connecting mechanism 4 includes a rear connecting frame 41, a front connecting frame 42 and a driving member, wherein the rear connecting frame 41 is used to connect to the forklift mast 3, the front connecting frame 42 is connected to the rear connecting frame 41 and is used to connect to the bottom supporting mechanism 5 and the top protection mechanism 6, and the driving member is used to drive the front connecting frame 42 to move horizontally on the rear connecting frame 41.

[0039] Combination Figure 5 , the rear connecting frame 41 is arranged vertically, and one side of the rear connecting frame 41 is provided with two rolling connecting members, each rolling connecting member includes a vertically arranged connecting plate 44, and two connecting plates 44 are installed with two main rollers 45 arranged up and down on one side away from each other, and the connecting plate 44 is installed with side rollers 46 on both sides above and below the main roller 45, and the axial direction of the side roller 46 is perpendicular to the axial direction of the main roller 45. It should be noted that the existing forklift mast 3 is generally provided with two vertically oppositely arranged C-shaped channel steels 31, and the two rolling connecting members on the rear connecting frame 41 of this embodiment are respectively arranged in a one-to-one correspondence with the two channel steels 31 of the forklift mast 3, and the two main rollers 45 and the two side rollers 46 of the rolling connecting member are both arranged in the corresponding channel steel 31, wherein the main roller 45 is in rolling contact with the two wing plates of the channel steel 31, and the side roller 46 is in rolling contact with the web of the channel steel 31. During installation, the two rolling connectors are respectively matched with the two channel steels 31 of the forklift mast 3, and the main rollers 45 and side rollers 46 of the rolling connector are inserted into the corresponding channel steels 31, so that the connection between the rear connecting frame 41 and the forklift mast 3 can be realized, and the main rollers 45 and side rollers 46 can roll up and down in the channel steels 31. Figure 6 In this embodiment, two oppositely arranged connecting seats 47 are provided at the top of the side of the rear connecting frame 41 away from the forklift mast 3, and a sliding hole is horizontally penetrated through the connecting seat 47, and the central axes of the sliding holes of the two connecting seats 47 coincide. A fixing seat 411 is also provided at the middle position of the side of the rear connecting frame 41 away from the forklift mast 3, and two oppositely arranged sliding grooves 49 are provided at the bottom of the side of the rear connecting frame 41 away from the forklift mast 3.

[0040] The front connecting frame 42 is arranged vertically and is located on the side of the rear connecting frame 41 away from the forklift mast 3. Two horizontally arranged side shift shafts 48 are arranged on the top of the front connecting frame 42. Both ends of the side shift shafts 48 are fixed to the front connecting frame 42 by bolts. The two side shift shafts 48 pass through two sliding holes respectively and the two side shift shafts 48 are respectively slidably matched with two connecting seats 47. Two oppositely arranged sliders 410 are installed at the bottom of the side of the front connecting frame 42 facing the rear connecting frame 41. The two sliders 410 are respectively slidably connected with two slide grooves 49 of the rear connecting frame 41. In this embodiment, a plurality of slots 412 arranged side by side are also opened at the bottom of the front connecting frame 42.

[0041] The driving member includes a side shift cylinder 43, which is arranged horizontally. The fixed end of the side shift cylinder 43 is fixed to the fixed seat 411 of the rear connecting frame 41 by bolts, and the telescopic end of the side shift cylinder 43 is fixed to the front connecting frame 42 by bolts. Due to the sliding cooperation between the side shift shaft 48 and the connecting seat 47 and the sliding cooperation between the slider 410 and the slide groove 49, when the side shift cylinder 43 is extended or retracted, the front connecting frame 42 can move horizontally to the left or right.

[0042] The bottom supporting mechanism 5 is used to support the support frame 2 at the bottom of the storage tank 1. In this embodiment, the bottom supporting mechanism 5 includes a guide shaft 51, two forks 52 and a screw rod 53. The guide shaft 51 is arranged horizontally and parallel to the side shift shaft 48. The middle and both ends of the guide shaft 51 are fixed to the front connecting frame 42. The screw rod 53 is located below the guide shaft 51 and is parallel to the guide shaft 51. The middle and both ends of the screw rod 53 are fixed to the front connecting frame 42. Two moving blocks 55 are slidably connected to the screw rod 53. The two forks 52 are arranged parallel and opposite to each other. Each fork 52 includes a horizontal section inserted at the bottom of the support frame 2 and a vertical section vertically connected to the horizontal section. A sleeve 54 is provided at the top of the vertical section and the sleeve 54 is slidably mounted on the guide shaft 51. The vertical sections of the two forks 52 are respectively connected to the two moving blocks 55 on the screw rod 53. In this embodiment, in order to prevent the forks 52 from moving left and right during the transportation process, chains 56 are connected to the vertical sections of the two forks 52, and a latch 57 is connected to the end of the chain 56 away from the forks 52. The latch 57 can be inserted into one of the slots 412 of the front connecting frame 42. Of course, in other embodiments, other means such as ropes can be used instead of the chain 56. In this embodiment, when transporting the storage tank 1, the two forks 52 are first pushed to move on the guide shaft 51 to adjust the distance between the two forks 52 according to the size of the support frame 2 at the bottom of the storage tank 1. After the distance between the two forks 52 is adjusted, the two latches 57 are respectively clamped in the two slots 412, and then the fork parts of the two forks 52 are inserted into the bottom of the support frame 2. Through the setting of the driving component, when transporting the storage tank, the fork 52 of the transport attachment needs to be forked into the bottom support frame 2 of the storage tank 1. If there is a left-right deviation between the fork 52 and the support frame 2, the front connecting frame 42 can be directly driven by the side shift cylinder 43 to move horizontally left and right to adjust the position of the fork 52, ensuring that the fork 52 is aligned with the bottom support frame 2 of the storage tank 1, thereby eliminating the need to reverse to adjust the fork position and improving the transport efficiency.

[0043] The top support mechanism is used to support the top of the storage tank 1 to prevent the storage tank 1 from tipping over. Figure 7 In this embodiment, the top support mechanism includes a protective frame 61 and two protective rods 62. The protective frame 61 is located above the front connecting frame 42. Two mounting frames 63 are provided at the bottom of the protective frame 61. The two mounting frames 63 are respectively located on both sides of the front connecting frame 42 and the two mounting frames 63 are connected to the front connecting frame 42 by bolts. The two protective rods 62 are located on both sides of the storage tank 1 and the distance between the two protective rods 62 is adjustable. The two protective rods 62 are vertically mounted on the protective frame 61. When in use, the distance between the two protective rods 62 is adjusted in advance according to the size of the storage tank 1, and then the two protective rods 62 are fixed to the protective frame 61.

[0044] Next, combine Figure 3 , the working principle of the tank handling attachment of this embodiment is explained.

[0045] Since the sizes of the storage tanks 1 are various, the size of the support frame 2 at the bottom of the storage tank 1 will also change with the size of the storage tank 1. When the storage tank 1 is transported by using this embodiment, the two rolling connectors of the rear connecting frame 41 are first respectively matched with the two channel steels 31 of the forklift gantry 3, and the main rollers 45 and the side rollers 46 of the rolling connector are inserted into the tops of the corresponding channel steels 31. Due to gravity, the main rollers 45 and the side rollers 46 roll along the channel steels 31, driving the rear connecting frame 41 to move to the bottom of the forklift gantry 3; then, according to the size of the storage tank 1 to be transported, the distance between the two protective rods 62 is adjusted, and according to the size of the support frame 2, the distance between the two forks 52 is adjusted; after the distance is adjusted, the forklift is started, driving the fork parts of the two forks 52 to be inserted into the bottom of the support frame 2, and at the same time, the two protective rods 62 are located on both sides of the storage tank 1 to protect the storage tank 1, and then the storage tank 1 can be transported to the designated position by the forklift.
