Description

Technical Field

[0001] The utility model relates to the technical field of storage tank construction, in particular to a plate-inverting transport trolley. Background Art

[0002] In petrochemical projects, the construction of double-layer vaulted storage tanks is often involved. This type of storage tank is often constructed using the inverted method, which involves on-site assembly and welding. The outer tank is constructed first, and then the inner tank. It is inevitable that the inner tank wall panel assembly and welding in the confined space are involved. However, it is difficult to lift the crane into place, and the steel plate is difficult to transport to the designated welding position of the inner tank. Larger steel plates can weigh up to 2 tons. In some installation scenarios, only small vehicles are allowed to transport steel plates. However, existing small vehicles cannot efficiently transport large-mass and large-area steel plates. This plan is launched in this context. Utility Model Content

[0031] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0033] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0034] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0035] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0036] like Figure 1-5 The illustrated inventive plate transport trolley comprises a rectangular frame 1, which serves as the main body of the frame, and a support beam 2 is arranged above the rectangular frame 1, which is parallel to the long side of the rectangular frame 1 and located in the middle, and a vertical support column 3 is arranged on the rectangular frame 1 for supporting the support beam 2. A mobile lifting ring 4 is sleeved on the support beam 2, and a fall chain 5 is hung on the mobile lifting ring 4. The chain hook of the fall chain 5 is placed under the rectangular frame 1 and is hung with the lifting ear on the steel plate to be installed. A connecting column 8 is vertically connected to the bottom of the long side of the rectangular frame 1, and a universal wheel 6 is installed at the bottom of the connecting column 8.

[0037] The length and width of the rectangular frame 1 can be designed to be 5000*1800mm, and the load of the fall chain 5 is designed to be 2t. In order to match steel plates of different specifications and sizes, it is necessary to change the position of the movable lifting ring 4 on the support beam 2. In this solution, a notch 7 is opened on the support beam 2, and the bottom of the notch 7 forms an arc bottom that matches the movable lifting ring 4. The inner side wall of the movable lifting ring 4 has more contact points with the arc bottom, and the side of the notch 7 can effectively prevent the movable lifting ring 4 from moving. The trolley moves slowly under the push of the workers and is used for horizontal lifting of small-scale steel plates in the tank installation area.

[0038] The rectangular frame 1 is welded from square steel of 50*50*4mm. In order to improve the structural strength of the trolley, a number of connecting beams with parallel short sides are welded on the rectangular frame 1. Preferably, three groups of connecting beams are provided, and they are respectively located at the four equal points of the long sides of the rectangular frame 1. The three groups of connecting beams are defined as the middle beam 12 in the middle and the side beams 13 on both sides, that is, the middle beam 12 divides the rectangular frame 1 into two symmetrical areas on the left and right, and the side beams 13 on each side divide each area into two smaller areas. A support column 3 is also welded in the middle of the middle beam 12 to support the support beam 2. In order to improve the stability of the support beam 2, a fourth reinforcing rib 14 is welded in the middle of the support beam 2 and in the middle of the two long sides of the rectangular frame 1.

[0039] Specifically, first reinforcing ribs 9 connected to the long sides of the rectangular frame 1 are welded on both sides of the connecting column 8. Second reinforcing ribs 10 connected to the middle of the side beam 13 extend outward from the inner corner of the rectangular frame 1, and third reinforcing ribs 11 connected to the middle of the side beam 13 extend outward from the inner corner formed by the middle beam 12 and the long sides of the rectangular frame 1. The first reinforcing ribs 9, the second reinforcing ribs 10, the third reinforcing ribs 11 and the fourth reinforcing ribs 14 can all be made of square steel of the rectangular frame 1.

[0040] Preferably, the second reinforcement rib 10 and the third reinforcement rib 11 are symmetrically arranged about the center beam 12, and the end edge of the second reinforcement rib 10 is in contact with the side center line of the side beam 13, so that the second reinforcement rib 10 or the third reinforcement rib 11 is directly welded to the side beam 13, and different small areas are divided into multiple triangular structures, so that the force is more reasonable and the load is larger.

[0041] 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 protection scope of the present invention.
