DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The lifting low bed semi-trailer provides two technical solutions:

[0027] like Figure 1-3 The first embodiment is shown: it includes a front vehicle 1 and a semi-trailer 2 hung behind it, and a cargo lifting and transporting mechanism is arranged at the rear of the semi-trailer 2, and the cargo lifting and transporting mechanism includes:

[0028] The lifting and flipping assembly 3 is a bilaterally symmetrical structure. The lifting and flipping assembly 3 includes a slide rail 31, which is fixedly connected to the rear end of the semi-trailer car 2. A limited guide groove 32 is provided on the left and right sides of the slide rail 31. A support plate 33 is movably connected between the two limited guide grooves 32. A hydraulic cylinder 34 is rotatably connected to the front of the slide rail 31. A slide groove 35 is provided at the bottom of the support plate 33, and a rotating connecting piece 36 is slidably connected to the inner surface of the slide groove 35. The telescopic end of the hydraulic cylinder 34 is rotatably connected to the rotating connecting piece 36. The limited guide groove 32 consists of a long groove and a circular groove. The support plate 33 is connected to the limited guide groove 32 through two left and right square blocks. The limited guide groove 32 can rotate after entering the circular groove. A T-slot 37 is provided inside the support plate 33. A T-block 38 is slidably connected inside the T-slot 37. The T-block 38 is fixedly connected to the bottom of the bottom plate 41.

[0029] The transport trolley 4 is composed of a bottom plate 41 and four universal wheels 42 at the bottom, and the transport trolley 4 can be installed on the lifting and flipping assembly 3 to move the goods up and down and transport them.

[0030] The locking assembly 6 is used to lock and fix the transport trolley 4 after it is installed on the lifting and flipping assembly 3. The locking assembly 6 includes a bolt head 61, and the bolt head 61 is fixed to the bottom of the T-block 38. A positioning groove 62 is provided at the bottom of the support plate 33. The bolt head 61 is locked by a locking nut 63 when it enters the positioning groove 62.

[0031] When loading and unloading goods, the goods are loaded and unloaded by the lifting assembly 3 and the transport trolley 4. The goods can be quickly transported by the transport trolley 4, and the transport trolley 4 can be turned over to form a baffle to protect the goods, thereby improving the practicability of the device when in use.

[0032] like Figure 3 A second embodiment is shown, which mainly differs from the first embodiment in that a fixing component 5 is arranged on the transport trolley 4 for fixing the goods, and the fixing component 5 includes two left and right mounting blocks 51, and the two mounting blocks 51 are fixedly connected to the bottom of the base plate 41, a bidirectional threaded rod 52 is rotatably connected between the two mounting blocks 51, and the left and right side surfaces of the bidirectional threaded rod 52 are threadedly connected with connecting blocks 53, and the top of the base plate 41 is provided with two left and right through grooves 54, and the two connecting blocks 53 extend from the two through grooves 54 to the top of the base plate 41, and the tops of the two connecting blocks 53 are respectively fixedly connected with clamping plates 55.

[0033] When the goods are transported by the transport trolley 4, the left and right sides of the goods are clamped and fixed by the fixing group 5, thereby ensuring the stability of the goods during transportation.

[0034] When in use, place the goods on the bottom plate 41, rotate the two-way threaded rod 52 so that the two connecting blocks 53 drive the two clamping plates 55 to approach the left and right sides of the goods, thereby clamping the goods and pushing the trolley to transport the goods. When transporting to the tail of the semi-trailer body 2, align and insert the T-block 38 with the T-slot 37. After insertion, start the two hydraulic cylinders 34 to make the two support plates 33 move up and down, so that the transport trolley 4 moves upward with the goods, and moves the goods to the semi-trailer body 2 after moving into place. After the goods are transported, the hydraulic cylinder 34 continues to push the transport trolley 4 upward, so that the square blocks on both sides of the support plate 33 enter the circular grooves of the limiting guide grooves 32. At this time, the transport trolley 4 will be turned over, so that the transport trolley 4 enters the vertical position, and finally the locking nut 63 is screwed into the bolt head 61, and the locking nut 63 is pressed tightly against the support plate 33.
