[0026] The following further describes the present utility model in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0027] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is lower than that of the second feature.

[0029] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] In the dismantling operation of electric motors in power plants, it is often necessary to move the motors from the mounting base to the maintenance area, and then move them from the maintenance area to the mounting base. During this process, there may be limited space, which may make it impossible to install the lifting tools. As a result, it is necessary to carry the motors manually or to set up lifting scaffolding on site to assist in the transportation. In this way, workers will be at risk of personal health damage in the process of carrying motors or setting up lifting scaffolding, and the construction and dismantling of lifting scaffolding will also increase the workload. Therefore, in this embodiment, a lifting and transporting integrated trolley is provided, which can be used in the lifting and transportation operations of workpieces, including but not limited to electric motors in power plants, etc., to reduce damage to workers' health and reduce workload.

[0031] Please refer to Figures 1 to 3 As shown, the integrated lifting trolley in this embodiment is used to lift an object 100 to be lifted which is supported on the ground. The integrated lifting trolley includes a trolley body 1, a lifting mechanism 2, and a bearing member 3. Among them, the trolley body 1 is provided with an entry and exit channel 16, and an entrance and exit 161 is provided at one end of the entry and exit channel 16. When the trolley body 1 moves toward the object 100 to be lifted supported on the ground, the entrance and exit 161 can allow the object 100 to pass through and enter the entry and exit channel 16; the lifting mechanism 2 is arranged on the trolley body 1 and is located above the entry and exit channel 16. The lifting mechanism 2 is used to lift the object 100 entering the entry and exit channel 16 to lift the object 100 off the ground; the bearing member 3 is movably arranged on the trolley body 1, and the bearing member 3 has an avoidance position and a carrying position. When the bearing member 3 is located at the avoidance position, the bearing member 3 is located outside the entry and exit channel 16. When the bearing member 3 is located at the carrying position, the bearing member 3 is located inside the entry and exit channel 16 and is located below the object 100 lifted by the lifting mechanism 2.

[0032] Specifically, in this embodiment, an access passage 16 and an inlet / outlet 161 are provided on the trolley body 1. Through the access passage 16 and the inlet / outlet 161, the trolley can be moved above the object 100 to be lifted, and then the lifting mechanism 2 on the trolley body 1 is used to lift the object 100. In this way, the object 100 on the ground can be lifted. A carrier 3 is also installed on the trolley body 1. When the lifting mechanism 2 is lifting, the carrier 3 is located outside the access passage 16 to prevent interference with the object 100 and the lifting mechanism 2. After the object 100 is lifted, the carrier 3 can be moved inside the access passage 16 and located below the object 100, and then the object 100 is placed on the carrier 3. Finally, the object 100 is moved to the target area by the trolley. With this arrangement, the carrier 3 ensures that the object 100 can remain stable during the movement process and will not cause the trolley to tip over. And after the lifting mechanism 2 lifts the object, by moving the carrier 3 below the lifting mechanism 2 and then lowering the lifted object 100 onto the carrier 3, the object 100 can be carried. The structure is simple and the operation is convenient, which is conducive to improving the lifting operation efficiency of the trolley.

[0033] Among them, in this embodiment, a scheme is exemplarily given where the object 100 is a motor, and in other embodiments, it can also be set as needed.

[0034] Optionally, as Figure 1 shown, the lifting and transporting integrated trolley further includes a limiting member 4. The trolley body 1 is further provided with a first limiting hole 11, and the carrier 3 is provided with a second limiting hole 31. When the carrier 3 is in the carrying position, the first limiting hole 11 communicates with the second limiting hole 31, and the limiting member 4 sequentially passes through the first limiting hole 11 and the second limiting hole 31. Specifically, in this embodiment, when the carrier 3 is placed inside the access passage 16, the limiting member 4 can be used to fix the positions of the trolley body 1 and the carrier 3 through the first limiting hole 11 and the second limiting hole 31, preventing the carrier 3 from moving during the transportation process, facilitating ensuring that the carrier 3 remains stable when the trolley moves along the extending direction, so that the trolley is more stable during operation and ensuring that the transported object 100 will not fall.

[0035] In this embodiment, the limiting member 4 is a pin shaft, and the trolley body 1 and the carrier 3 are fixed through the pin connection of the pin shaft. In other embodiments, the limiting member 4 can also be a bolt, and the trolley body 1 and the carrier 3 are threadedly connected together through the bolt, thereby realizing the fixation of the trolley body 1 and the carrier 3.

[0036] Optionally, as Figure 1 and Figure 2As shown, along the extending direction of the access passage 16, the trolley body 1 is provided with a sliding groove 12, and the carrier 3 is slidably arranged in the sliding groove 12. Specifically, in this embodiment, a sliding groove 12 is formed on the trolley body 1. The sliding groove 12 is communicated with the access passage 16 and the access port 161. The carrier 3 slides in and out of the trolley body 1 through the sliding groove 12, which is convenient for ensuring the stability of the carrier 3 when the trolley moves in the width direction, with convenient operation and simple structure, which is beneficial to manual operation and reduces the manufacturing cost.

[0037] Furthermore, as Figure 1 and Figure 2 shown, in this embodiment, the trolley body 1 includes a chassis 13, wheels 14 arranged on the chassis 13, and a frame 15 arranged above the chassis 13. The chassis 13 and the frame 15 enclose an access passage 16. The sliding groove 12 is arranged on the chassis 13, and the carrier 3 is slidably connected to the chassis 13. In other embodiments, the sliding groove 12 can also be arranged on the frame 15 according to needs.

[0038] Furthermore, as Figure 1 and Figure 2 shown, in this embodiment, the chassis 13 includes two U-shaped support plates 131 arranged in parallel and spaced apart in the vertical direction, as well as a first side plate 132 and a second side plate 133. The U-shaped support plate 131 includes a first plate 1311 and a second plate 1312 arranged in parallel and spaced apart, and a third plate 1313 connecting the first plate 1311 and the second plate 1312. The first side plate 132 is connected between the first plates 1311 of the two U-shaped support plates 131, and the second side plate 133 is connected between the second plates 1312 of the two U-shaped support plates 131. The two U-shaped support plates 131, the first side plate 132, and the second side plate 133 enclose the sliding groove 12. Such an arrangement facilitates the processing of the chassis 13 and is convenient for ensuring the support stability of the chassis 13 for the carrier 3.

[0039] Furthermore, as Figure 1 and Figure 2 shown, in this embodiment, the frame 15 includes a plurality of vertical rods 151, a top frame 152, and a mounting seat 153. The top frame 152 is arranged in parallel and spaced apart from the chassis 13 in the vertical direction. A plurality of vertical rods 151 are connected between the chassis 13 and the top frame 152. A part of the plurality of vertical rods 151 is located on one side of the access passage 16 in the width direction, and another part of the plurality of vertical rods 151 is located on the other side of the access passage 16 in the width direction. The width direction, the extending direction, and the vertical direction of the access passage 16 are perpendicular to each other pairwise. The mounting seat 153 is arranged on the top frame 152, and the lifting mechanism 2 is arranged on the mounting seat 153. The structure is simple and can ensure the support stability.

[0040] Furthermore, as Figure 1 andFigure 2 As shown, the position of the mounting seat 153 relative to the top frame is adjustable in the width direction. With this setting, the position of the lifting point of the lifting mechanism 2 can be adjusted according to actual needs in the width direction. The lifting point of the lifting mechanism 2 is moved along the width direction according to the lifting point of the object 100 to be lifted, ensuring the stability of the center of gravity during lifting. Specifically, as Figures 1 to 3 shown, in this embodiment, the mounting seat 153 includes a cross bar 1531 and two supports 1532 provided at both ends of the cross bar 1531. The two supports 1532 are fixedly provided on the top frame 152. The lifting mechanism 2 includes a sliding sleeve 21 and a lifting tool 22 provided on the sliding sleeve 21. The sliding sleeve 21 is slidably provided on the cross bar 1531.

[0041] In other embodiments, the position of the lifting mechanism 2 relative to the top frame 152 can also be made adjustable along the extending direction according to needs.

[0042] Furthermore, as Figure 3 shown, in this embodiment, the lifting tool 22 and the sliding sleeve 21 are snap-connected. With this setting, it is convenient to disassemble the lifting tool 22 from the sliding sleeve 21, and the corresponding specification of the lifting tool 22 can be replaced according to the weight of the object 100 to be lifted, thereby improving the practicality of the trolley.

[0043] Further, as Figure 1 and Figure 2 shown, the support 1532 includes two support rods 15321. The two support rods 15321 are arranged at an angle. The bottom end of the support rod 15321 is connected to the top frame 152, and the top end of the support rod 15321 is connected to the cross bar 1531. With this setting, the support 1532 can be made triangular, increasing the stability of the support 1532, thereby ensuring the stability of the lifting mechanism 2 during lifting.

[0044] Further, as Figure 3 shown, the lifting tool 22 is a chain block or an electric hoist. In this embodiment, the lifting tool 22 is specifically a chain block. The chain block has a relatively low cost and is not easily damaged. In other embodiments, the lifting tool 22 can also be an electric hoist, and the specific type of the lifting tool 22 is selected according to needs.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
