Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0024] First, the terms that may be used in this article are explained as follows:

[0025] The term “and / or” means that either or both of them can be realized at the same time. For example, X and / or Y means both “X” or “Y” and “X and Y”.

[0026] The terms "include", "comprises", "contains", "has" or other descriptions with similar semantics should be interpreted as non-exclusive inclusion. For example, including certain technical feature elements (such as raw materials, components, ingredients, carriers, dosage forms, materials, dimensions, parts, components, mechanisms, devices, steps, procedures, methods, reaction conditions, processing conditions, parameters, algorithms, signals, data, products or products, etc.) should be interpreted as including not only certain technical feature elements explicitly listed, but also other technical feature elements known in the art that are not explicitly listed.

[0027] The term "consisting of..." means excluding any technical feature elements not explicitly listed. If this term is used in a claim, it will make the claim closed, so that it does not contain technical feature elements other than the technical feature elements explicitly listed, except for the conventional impurities related to them. If this term only appears in a clause of a claim, it only limits the elements explicitly listed in the clause, and the elements recorded in other clauses are not excluded from the overall claim.

[0028] The term "parts by mass" refers to the mass ratio relationship between multiple components. For example, if it is described that component X is x parts by mass and component Y is y parts by mass, then the mass ratio of component X to component Y is x:y. 1 part by mass can represent any mass, for example, 1 part by mass can be represented as 1 kg or 3.1415926 kg. The sum of the parts by mass of all components is not necessarily 100 parts, but can be greater than 100 parts, less than 100 parts or equal to 100 parts. Unless otherwise specified, the parts, proportions and percentages described herein are all measured by mass.

[0029] Unless otherwise specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example: it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0030] When concentration, temperature, pressure, size or other parameters are expressed in the form of a numerical range, the numerical range should be understood to specifically disclose all ranges formed by the pairing of any upper limit, lower limit, and preferred value in the numerical range, regardless of whether the range is explicitly stated; for example, if a numerical range of "2 to 8" is stated, the numerical range should be interpreted as including ranges such as "2 to 7", "2 to 6", "5 to 7", "3 to 4 and 6 to 7", "3 to 5 and 7", "2 and 5 to 7", etc. Unless otherwise specified, the numerical ranges stated herein include both their end values ​​and all integers and fractions within the numerical range.

[0031] The orientation or position relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or position relationship shown in the drawings and are only for the convenience and simplification of description, and do not explicitly or implicitly indicate that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of this document.

[0032] The embodiments of the utility model will be described in further detail below in conjunction with the accompanying drawings.

[0033] Embodiment 1

[0034] like Figures 1 to 5As shown, a special trolley for rotating object handling tooling is used to carry rotating objects; the structure includes a bottom plate 1, a rotating body bracket 2 and a handrail 3; the rotating body bracket 2 is arranged above the bottom plate 1 to support the rotating object; specifically, as Figure 3 As shown, the rotating body bracket 2 has two side-by-side arrangements; they include a support plate 21, a bracket 22 and a pad 23; the lower part of the bracket 22 is fixedly connected to the upper part of the bottom plate 1; it is welded by section steel, and the whole can be fixed by welding or screw connection. The upper part of the bracket 22 is fixedly connected to the support plate 21; it can be fixed to the bracket 22 by welding or screw connection. The upper surface of the support plate 21 is a concave arc surface, and a pad 23 is provided on the upper part, and the pad 23 includes a rubber plate or a plastic plate. The pad 23 is fixed to the support plate 21 by countersunk screw bolts, or it can be bonded, depending on the shape of the upper surface of the support plate 21. It is used for appearance protection when supporting rotating body objects. The concave arc angle is 120 to 180°. Generally, it can be less than 180°, a little smaller. It is convenient to put in rotating body objects, and it is also better not to be less than 120° to prevent rotating body objects from falling. When carrying the rotating body articles, they can be stably placed on the rotating body bracket 2 of the trolley, and the pad 23 contacts the articles, thereby greatly reducing the damage to the articles during the transportation.

[0035] The upper surface of the support plate 21 can also be a concave spherical surface, a V-shaped surface or an inverted trapezoidal surface; wherein the cross-sectional sector angle of the spherical surface is 120-180°; generally, it may not reach 180°, but may be slightly smaller. It is convenient to put in the rotating object, and it is also better not to be less than 120° to prevent the rotating object from falling. The V-shaped surface or the inverted trapezoidal surface needs to be designed according to the size of the rotating object, and will not be repeated here.

[0036] The bottom plate 1 is provided with armrest accommodating cavities 11 in the front-to-back direction on the left and right sides respectively; the armrest accommodating cavity 11 is formed by folding and pressing a steel plate and welded on the bottom plate 1, and the armrest accommodating cavity 21 is provided with slide grooves 12 in the front-to-back direction on the left and right sides; specifically, the slide grooves 12 can be processed on both sides of the armrest accommodating cavity 21; the armrest 3 is U-shaped, specifically, a round tube is bent into a U-shape; the lower ends of the two straight arm sections 31 are connected to the slide grooves 12 respectively through two connecting pins 4; the armrest accommodating cavity 11 is used to accommodate the straight arm sections 31 of the armrest 3. Pin holes are opened at the lower ends of the two straight arm sections 31, and the connecting pins 4 pass through the slide grooves 12 on both sides and the pin holes at the lower ends of the straight arm sections 31. Retaining rings 8 are installed on both sides of the straight arm section 31, and a split pin 10 is installed on the other side to achieve the connection between the armrest 3 and the armrest accommodating cavity 21.

[0037] The armrest 3 is laid flat and moved from the rear end to the front end along the slide groove 12 by the connecting pin 4; the straight arm section 31 of the armrest 3 is placed in the armrest accommodating cavity 21; the armrest 3 is pulled out backward and folded upward, and the lower ends of the two straight arm sections 31 of the armrest 3 are locked by the locking mechanism to position the armrest 3.

[0038] Here, the locking mechanism includes a locking groove 13 provided at the rear end of the slide groove 12 and extending downward, and a locking stopper 5 provided below the armrest accommodating cavity 21 in front of the locking groove 13; the locking groove 13 is integrally processed along the slide groove 12. The locking stopper 5 is welded below the armrest accommodating cavity 21.

[0039] When the armrest 3 is used, the armrest 3 is pulled out and then folded upward, and the connecting pins 4 at the lower ends of the two straight arm sections 31 of the armrest 3 are inserted into the locking grooves 13 downward, and the lower ends of the straight arm sections 31 abut against the locking block 5, thereby locking and positioning the armrest 3. When the special trolley is pushed, the armrest 3 is prevented from rotating, and the special trolley can be pushed away safely.

[0040] When the armrest 3 needs to be stored, the armrest 3 is lifted upward, the connecting pin 4 is lifted upward from the locking groove 13, and placed in the slide groove 12. After the armrest 3 is rotated around the connecting pin 4 and laid flat, it can be pushed into the armrest accommodating cavity 11 along the slide groove 12 and hidden and stored. This can prevent the armrest 3 from affecting the placement of items when carrying large items. It does not affect the carrying of items on the trolley at all, and also reduces the floor space. It reduces the occupied space and does not block the carrying of items at all.

[0041] A front caster 6 is installed on the left and right sides of the bottom of the base plate 1, which can be installed by screws through the mounting seat 9; a rear universal caster 7 is installed on the left and right sides of the rear, which can be installed by screws; the rear universal caster 7 is provided with a brake pedal 71. The base plate 1 is welded from steel plates, which is strong and reliable. The front caster 6 and the rear universal caster 7 are heavy-duty casters to meet the load-bearing requirements. The base plate 1 can also be composed of other materials, such as plastic, stainless steel, aluminum plate, etc.

[0042] When the connecting pin 4 of the handrail 3 is in the locking groove 13, the trolley can be pushed away. When the connecting pin 4 is lifted upward from the locking groove 13 and placed in the slide groove 12, the handrail 3 is rotated around the connecting pin 4 and laid flat, and can be pushed into the handrail accommodating cavity 11 along the slide groove 12 and hidden and retracted.

[0043] This example has the following advantages:

[0044] 1. Special rotating object handling, special bracket with special rotating object, fixed reliably and not easy to fall.

[0045] 2. Simple structure, large load-bearing capacity, strong and durable, not easy to damage.

[0046] 3. The armrest can be rotated and stored under the vehicle, which does not take up space and does not affect the transportation of items.

[0047] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
