Description

Technical Field

[0001] The invention belongs to the technical field of warehousing and logistics, and in particular relates to a packaging box beam type sling transfer vehicle. Background Art

[0002] During the lifting process, packaging boxes usually need to be lifted using beam-type slings. Large-sized and heavy-loaded packaging boxes require special slings for use, so the slings need to be frequently loaded and unloaded, transferred and stored. Currently, there is a lack of transfer vehicles or placement racks on the market that can meet the needs of both sling transfer and placement. The slings need to be repeatedly moved between the placement racks and transfer vehicles, which is not only inefficient but also easy to cause damage to the slings. Common sling transfer devices have poor versatility and are not compatible with most beam-type slings. They are prone to damage to the slings during loading, unloading and transfer. In the prior art, sling placement racks are mostly ordinary cantilever racks. Due to the complex structure and different sizes of the slings, cantilever racks cannot meet the placement requirements of most slings. Therefore, it is necessary to improve the existing sling placement racks. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a packaging box beam type spreader transfer vehicle.

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] A packaging box beam type sling transfer vehicle comprises a lower support structure, an upper support structure and two groups of side support units; the lower support structure comprises an H-shaped underframe, with bottom beams respectively provided on the front and rear sides of the H-shaped underframe, and each group of side support units comprises side support structures symmetrically arranged on both sides of the bottom beam, the side support structure comprises inner pillars and outer pillars, the top end of the inner pillars is lower than the outer pillars, a top beam is horizontally provided between the top end of the inner pillars and the outer pillars, a cross beam is provided between the two inner pillars of each group of side support units, and the upper end faces of the cross beams in each side support structure are of the same height; the upper support structure comprises two upper pillars arranged in parallel, each upper pillar is respectively fixed at both ends to the inner pillars of the corresponding side support structure, and the upper end face of the upper pillar is lower than the inner pillar; a number of reinforcing pillars are provided between the two upper pillars, and a walking wheel is installed at the lower end of each outer pillar.

[0006] Furthermore, the upper supporting structure also includes a pad, which covers the upper end surfaces of the two upper pillars at the same time.

[0007] Furthermore, a hollow portion is provided in the middle of the pad.

[0008] Furthermore, the base frame includes two lower supports arranged in parallel, a transverse connecting column is provided between the two lower supports, and the transverse connecting column is arranged corresponding to the middle part of the lower supports.

[0009] Furthermore, an electrostatic belt is installed on the lower support or the cross-connecting column.

[0010] Furthermore, a reinforcing rib plate is provided between the inner support and the bottom beam.

[0011] Furthermore, a reinforcing rib is provided between each inner support and the cross beam.

Those skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] A packaging box beam type spreader transfer vehicle, such as Figures 1 to 4 As shown, it includes a lower support structure, an upper support structure and two groups of side support units. Each structural member adopts square tubes and steel plates respectively, which are welded together to form a frame structure; the lower support structure includes an H-shaped underframe 1, and bottom beams 2 are respectively provided on the front and rear sides of the H-shaped underframe. Each group of side support units includes side support structures symmetrically arranged on both sides of the bottom beam. The side support structure includes inner pillars 3 and outer pillars 4. The top of the inner pillar is lower than the outer pillar. A top beam 5 is horizontally provided between the top of the inner pillar and the outer pillar.

[0026] A crossbeam 6 is provided between the two inner pillars of each group of side support units, and the upper end surfaces of the crossbeams in each side support structure are of the same height; the upper support structure includes two upper pillars 7 arranged in parallel, and the two ends of each upper pillar are respectively fixed to the inner pillars of the corresponding side support structure, the upper end surface of the upper pillar is lower than the inner pillar, and the crossbeam is arranged at the same height as the upper pillar.

[0027] Several reinforcing columns 8 are provided between the two upper pillars, and a running wheel 9 is installed at the lower end of each outer pillar. As an example, the running wheel adopts a universal wheel with a built-in brake device. A fixed plate is provided at the lower end of the outer pillar, and the running wheel can be detachably installed on the fixed plate. An anti-static belt is installed on the lower pillar or the cross-connecting column to effectively eliminate static electricity. The anti-static belt can be a commercially available product. In a further improved solution, anti-static rubber is provided on the upper surface of the top beam and the upper surface of the pad to provide protection, shock absorption and anti-static effects. In order to improve the stability of the structure, a reinforcing rib is provided between the inner pillar and the bottom beam. A reinforcing rib is provided between each inner pillar and the cross beam.

[0028] The upper support structure also includes a pad 10, which covers the upper end surfaces of the two upper pillars. Preferably, the pad has a hollow 11 in the middle. As an example, the chassis includes two lower pillars 12 arranged in parallel, with a cross-connecting column 13 provided between the two lower pillars, and the cross-connecting column is arranged corresponding to the middle of the lower pillar. In the scheme with the hollow in the middle of the pad, a space is formed in the middle of the spreader transfer vehicle for the lifting ring to settle, which can be used to place the lifting ring of the spreader to prevent squeezing and damage to the spreader.

[0029] When in use, the spreader is inverted, with the lifting ring placed in the reserved ring-settling space in the middle of the upper support structure. The small crossbeam is placed on the upper support structure's pad and restrained by the inner support pillars, while the large crossbeam is placed in the groove between the two sets of side support units and restrained by the outer support pillars. For safety, two tie-down straps can be used for fastening and reinforcement. To move the spreader, simply release the travel wheel brakes and gently push the carrier to transport it. After moving it to the tooling storage area, the travel wheels can be braked and the spreader can be stored.

[0030] The invention adopts a frame structure, which is easy to process and has low cost. After the lifting is completed, the sling is placed in the support frame and can be transported to the tooling storage area over a long distance. There is no need to repeatedly move the sling between the placement frame and the transfer vehicle. Since the upper side of the pad of the upper support structure and the upper side of the top beam of the side support structure respectively form storage spaces for slings of different specifications, it can adapt to long-term storage and convenient transportation of beam-type slings of different specifications.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
