[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0018] like Figure 1 and Figure 2 As shown, the trolley capable of transporting objects in narrow spaces includes a frame 1, with a mounting frame 2 at one end of the frame 1. A lifting seat 3 is located within the mounting frame 2, and a gripping mechanism is located at the bottom of the lifting seat 3. The gripping mechanism connected to the lifting seat 3 can transport objects in narrow spaces, improving object handling efficiency. A servo motor 32 provides power for the opening and closing of the gripping mechanism, enabling it to handle objects of a certain size. A drive motor 21 provides power for the lifting and lowering of the gripping mechanism, allowing the gripper 4 to reach different required heights, thus meeting the requirements of various gripping scenarios.

[0019] like Figure 4As shown, the gripping mechanism includes two opposing grippers 4. A mounting plate 31 is connected to the bottom of a lifting seat 3, perpendicular to the lifting seat 3. Two drive gears 33 are rotatably connected to the bottom of the mounting plate 31, meshing together. A servo motor 32 is mounted on the mounting plate 31, with its output end connected to the drive gears 33. Each drive gear 33 is fixedly connected to a first link 34, the end of which is hinged to the end of the gripper 4. A second link 35 is hinged between the gripper 4 and the mounting plate 31. Each gripper 4 forms a four-bar linkage via the first link 34 and the second link 35. The servo motor 32 provides power to control the opening and closing of the grippers 4 and precisely adjust their angle. The gripping force can be flexibly adjusted according to the actual situation of the object, ensuring a firm grip during the gripping phase and a smooth release during the release phase, guaranteeing the smooth operation of the entire gripping and handling process. The output end of the servo motor 32 is connected to a drive rod 37. One of the drive gears 33 has a groove at the bottom that matches its shape. The drive rod 37 is located in the groove and is connected by bolts to ensure a tight connection between it and the drive gear 33. This prevents the entire device from malfunctioning due to loose connections during operation, thus maintaining the integrity of the overall structure and the stability of collaborative work.

[0020] like Figure 3 As shown, racks 38 are fixedly connected to both sides of the lifting seat 3. The racks 38 are vertically arranged. A drive motor 21 is mounted on the mounting frame 2. The output end of the drive motor 21 is connected to a gear set 22, which meshes with the racks 38. The gear set 22 includes four gears. The output end of the drive motor 21 drives one of the gears, and two of the gears mesh with the two racks 38 respectively, realizing the stable lifting and lowering movement of the lifting seat 3. The mounting frame 2 serves as the moving track for the lifting seat 3, ensuring smooth linear movement of the lifting seat 3. This, in turn, enables the gripping mechanism to achieve stable lifting and lowering, providing accurate height adjustment for precise gripping.

[0021] like Figure 5 As shown, multiple sliding shafts 36 are provided on both sides of the lifting seat 3, and sliding grooves 23 are provided on both sides of the mounting frame 2. The sliding shafts 36 are slidably connected in the sliding grooves 23. During the lifting movement of the lifting seat 3, the sliding shafts 36 slide synchronously with the lifting seat 3 in the sliding grooves 23. The diameter of the sliding shafts 36 is slightly smaller than the width of the sliding grooves 23. The sliding grooves 23 limit the sliding shafts 36 in the horizontal direction, that is, they limit and support the lifting seat 3 and its components. This can firmly fix the rack 38 in the predetermined position, so that it will not deviate or loosen when meshing with the gear. This prevents the lifting seat 3 from tilting forward due to the weight of the object being gripped, avoiding affecting the smooth meshing of the gear and rack 38. This helps maintain the stability of the lifting mechanism and the overall stability of the gripping mechanism structure, providing a stable basis for the height adjustment of the gripping mechanism, and thus ensuring that the gripping mechanism can accurately perform gripping work.

[0022] like Figure 1 and Figure 2 As shown, the trolley capable of transporting objects in narrow spaces also includes wheels 11. The frame 1 includes platforms 12, with three platforms 12 arranged in parallel. Support rods 13 are fixedly connected between adjacent platforms 12. Each platform 12 has multiple mounting holes 14 and mounting slots 15. The platform 12 at the bottom of the frame 1 has a wheel motor 16 and a battery compartment 17. The main body of the frame 1 consists of three identical platforms 12. Adjacent platforms 12 are fixed and supported by multiple vertical profiles, giving the trolley a certain load-bearing capacity. The bottom platform 12 is used to install the battery, wheels 11, and wheel motor 16. The middle and top platforms 12 have a certain space above them, and each platform 12 is equipped with multiple mounting holes 14 and mounting slots 15 for installing or selecting other components or meeting the needs of temporary storage of items.

[0023] like Figure 4 As shown, the inner side of the end of the gripper 4 is provided with pressure teeth 41. The pressure teeth 41 increases the friction between the gripper 4 and the object being gripped, increases the stability of the object being gripped during the handling and transfer process, and also serves as a safety measure to effectively prevent accidents and improve the safety of the trolley operation process.

[0024] like Figure 5 As shown, a horizontal plate 24 is provided on one side of the mounting frame 2. The horizontal plate 24 is perpendicular to the mounting frame 2 and is fixedly connected to the front end of the frame 1. The platform 12 is fixed to the horizontal plate 24 with bolts to ensure the stable installation of the mounting frame 2. The overall width of the trolley is consistent with the wheelbase width, and the lifting seat 3 is located at the front end of the frame 1, making the structure more compact.

[0025] like Figure 1 and Figure 2 As shown, an infrared sensor 18 is provided at the end of the platform 12 in the middle of the frame 1. There are four infrared sensors 18, which are located at the four ends of the middle platform 12 respectively. The infrared sensors 18 are used to measure the distance between the vehicle and surrounding obstacles, so that the external controller can adjust the position of the vehicle according to the distance feedback of the infrared sensors 18, which facilitates the movement and operation of the vehicle in narrow spaces.

[0026] like Figure 5 As shown, both the mounting frame 2 and the lifting base 3 are provided with multiple weight-reducing holes 25. The above structure plays a role in structural weight reduction, which helps to reduce the moving resistance of the trolley.

[0027] The servo motor 32 is an SG90 servo motor, and the drive motor 21 is a stepper motor. The lifting mechanism and the gripping mechanism work together. Under the coordination of the control system, the servo motor 32 and the drive motor 21 can precisely control the lifting and lowering of the gripping mechanism as well as its opening and closing movements. The close cooperation between the gripping and lifting mechanisms can effectively meet the gripping needs of objects at different heights and positions. Compared with traditional handling equipment or tools, this trolley has a higher degree of automation and flexibility, is easier to operate, has a certain load capacity, and is safer to use.

[0028] The handling process is divided into four stages: positioning, where the target object is precisely located by moving the trolley and adjusting the position of the gripping mechanism; clamping, where the gripper 4 is driven by the servo motor 32 to clamp the object; transport, where the trolley moves to transport the clamped object to the designated location; and release, where the servo motor 32 again controls the gripper to open and close, releasing the object. Through the orderly operation of positioning, clamping, transport, and release, and in coordination with the lifting of the gripping mechanism and the movement of the trolley in each stage, objects of different shapes and sizes can be stably gripped and transported, achieving efficient object transfer operations.

[0029] This trolley, capable of transporting objects in confined spaces, integrates a gripping mechanism with the trolley. The gripping mechanism and gripper are equipped with a drive motor 21 for lifting and lowering, and a 180-degree servo motor 32 for opening and closing the gripper. These two drive systems coordinate their movements under the control system to complete the object gripping, solving the problem of gripping objects of different positions and sizes in confined spaces. It also solves the problems of difficult and inefficient object transport in confined spaces, making transport work in limited spaces more convenient and efficient.
