Description

Technical Field

[0001] This utility model belongs to the field of power electrical equipment technology, and specifically relates to an auxiliary equipment for power electrical equipment maintenance operations, and more specifically to an intelligent transfer vehicle. Background Technology

[0002] As is well known, the safety and reliability of the operation and maintenance of industrial electrical equipment is a primary concern for power supply departments.

[0003] For example, in the industrial power electrical equipment sector, 10kV power systems are commonly used. Indoor AC withdrawable switchgear is a complete set of power distribution equipment for single busbar and single busbar segmented systems. This type of switchgear can be used in power plants, power transmission from small and medium-sized generators, power distribution in industrial and mining enterprises, as well as power receiving and transmission in secondary substations of power systems and starting of large high-voltage motors. It plays an important role in controlling, protecting, and monitoring power equipment, and is crucial for the operation and protection of power equipment in power systems.

[0004] Transfer vehicles are essential maintenance tools for the distribution room in a substation. Specifically, intelligent transfer vehicles are mainly used for the transfer and maintenance of circuit breaker trolleys and current transformers in electrical equipment, in order to improve the efficiency of substation maintenance and reduce labor intensity.

[0005] The existing transfer vehicles do not have a structure to drive their movement. They rely entirely on manual pushing and pulling. The transfer vehicles themselves are heavy, and if the equipment to be maintained, such as circuit breaker trolleys or current transformers, is also carried on them, the overall weight of the transfer vehicle becomes even greater. This means that several operators are needed to push the transfer vehicle, which is quite time-consuming and labor-intensive, wasting human resources. Furthermore, the heavy transfer vehicle makes it difficult to control the pushing and pulling direction, which greatly reduces the efficiency of the transfer vehicle's movement. Utility Model Content

[0006] The purpose of this invention is to solve the problems of the prior art and provide an intelligent transfer vehicle that can travel along a predetermined path in a convenient, efficient and controllable manner.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An intelligent transfer vehicle includes: a frame, casters rotatably mounted on the side of the frame and partially protruding from the bottom of the frame, and a drive wheel capable of moving the casters.

[0009] Preferably, the frame includes a base and columns arranged longitudinally from the four corners of the base; the drive wheel is movably mounted between two adjacent columns.

[0010] More preferably, the casters are rotatably mounted on the base or column.

[0011] Preferably, a fixing plate is horizontally arranged between two adjacent columns, and an electric cylinder is provided at the bottom of the fixing plate to cause the drive wheel to move up and down.

[0012] More preferably, the electric cylinder has an electric cylinder body and an electric cylinder shaft extending from one end of the electric cylinder body, the electric cylinder shaft is mounted on the fixed plate, and the electric cylinder body is fixedly connected to the drive steering wheel.

[0013] Preferably, it further includes a steering wheel mounting plate, the electric cylinder body is fixed to one surface of the steering wheel mounting plate, and the drive steering wheel is mounted on the other opposite surface of the steering wheel mounting plate.

[0014] More preferably, it also includes a side plate, on which a first support wall and a second support wall located below the first support wall are provided; a guide rod is provided between the first support wall and the second support wall, the guide rod passing through the steering wheel mounting plate, so that the steering wheel mounting plate is slidably disposed between the first support wall and the second support wall.

[0015] Preferably, a compression spring sleeved on the guide rod is provided between the steering wheel mounting plate and the second support wall.

[0016] Preferably, the frame further includes a pair of longitudinal beams and a pair of transverse beams connecting two adjacent columns at their top ends.

[0017] More preferably, the pair of longitudinal beams are arranged in parallel, the pair of transverse beams are arranged in parallel, and each longitudinal beam is perpendicular to the adjacent transverse beam.

[0018] The beneficial effects of the technical solution provided by this utility model are as follows: In this utility model, since casters and drive wheels that drive the casters to rotate are installed on the frame of the intelligent transfer vehicle, when the drive wheels extend downward to contact the ground, the drive wheels roll relative to the ground, thereby providing a moving force for the entire intelligent transfer vehicle, allowing the intelligent transfer vehicle to move on the ground. The casters are located on the side of the frame and protrude from the bottom surface of the frame, which lowers the center of gravity of the intelligent transfer vehicle and improves the stability of the transfer vehicle device.

[0026] It should be noted that the concepts of "first" and "second" mentioned in this utility model are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to necessarily be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0027] refer to Figure 1-3 According to one embodiment of the present invention, an intelligent transfer vehicle 100 is provided, which has a walking device 50 for enabling the intelligent transfer vehicle 100 to travel along a predetermined path whether loaded or empty.

[0028] The intelligent transfer vehicle 100 includes a frame 10, casters 52 rotatably disposed on the side of the frame 10 and partially protruding from the bottom surface of the frame 10, and a drive steering wheel 54 that can be lifted and lowered on the frame 10. The drive steering wheel 54 can drive the casters 52 to move.

[0029] When the drive wheel 54 extends downward to a certain extent, the drive wheel 54 begins to contact the ground. Then, as the drive wheel 54 rolls relative to the ground, it provides a moving force to the entire intelligent transfer vehicle 100, causing the intelligent transfer vehicle 100 to move on the ground.

[0030] Specifically, after receiving an external drive signal, such as a drive signal from an external electrical control box, the drive wheel 54 begins to roll relative to the ground. Due to the relative relationship between action and reaction forces, the drive wheel 54, together with the casters 52, rolls relative to the ground, thereby realizing the walking function of the entire intelligent transfer vehicle 100.

[0031] In addition, a direction control mechanism (not shown) is installed inside the drive wheel 54. When an external steering drive signal is received, the drive wheel 54 deviates at a certain angle relative to the frame 10, thereby realizing the steering function during the movement of the intelligent transfer vehicle 100.

[0032] In one embodiment, the frame 10 includes a base 12, columns 14 arranged longitudinally from the four corners of the base 12, and a pair of longitudinal beams 18 and a pair of transverse beams 16 connecting two adjacent columns 14 at their top ends. The pair of longitudinal beams 18 are arranged in parallel, the pair of transverse beams 16 are arranged in parallel, and each longitudinal beam 18 is perpendicular to the adjacent transverse beam 16.

[0033] The drive wheel 54 is movably mounted between two adjacent columns 14. Since the drive wheel 54 needs to generate sufficient power to move the entire intelligent transfer vehicle 100, it must be securely fixed to resist the strong reaction force generated when it rolls, thus preventing structural deformation at the mounting location and avoidance of the drive wheel 54 becoming loose. Therefore, the drive wheel 54 needs to be fixed to a component with sufficient structural strength and rigidity. For example, in one embodiment, the drive wheel 54 is fixed between two adjacent columns 14.

[0034] More preferably, the casters 52 are rotatably mounted on the base 12 or the column 14. Since the base 12 is lower in height than the rest of the frame 10, its center of gravity is lower. Mounting the casters 52 on the base 12 improves the stability of the entire intelligent transfer vehicle during movement and avoids the risk of the intelligent transfer vehicle overturning due to hitting obstacles when its center of gravity is higher.

[0035] In one embodiment, a fixing plate 56 is horizontally arranged between two adjacent columns 14, and an electric cylinder 542 is provided at the bottom of the fixing plate 56 to cause the drive steering wheel 54 to move up and down. In this way, the electric cylinder 542 is fixed between the two adjacent columns 14, that is, fixed to the frame 10. The electric cylinder 542 is used to rotatably extend the drive steering wheel 54 out of the base 12 to contact the ground or retract it back into the base 12 to disengage from the ground.

[0036] For example, the electric cylinder 542 has an electric cylinder body 5422 and an electric cylinder shaft 5424 extending from one end of the electric cylinder body 5422. The electric cylinder shaft 5424 is mounted on the fixed plate 56, and the electric cylinder body 5422 is fixedly connected to the drive steering wheel 54.

[0037] When an external drive signal is applied to the electric cylinder 542, the electric cylinder shaft 5424 extends relative to the electric cylinder body 5422. Since the electric cylinder shaft 5424 is fixed to the fixed plate 56, and the fixed plate 56 itself is fixed relative to the two adjacent columns 14, the electric cylinder body 5422 moves downward. Correspondingly, the drive steering wheel 54, which is fixedly connected to the electric cylinder body 5422, also moves downward and comes into contact with the ground. As the drive steering wheel 54 rolls relative to the ground, the intelligent transfer vehicle 100 moves as a whole, thereby realizing the transportation of the equipment to be repaired, such as current transformers and circuit breakers, on the intelligent transfer vehicle 100 to the destination for maintenance.

[0038] Preferably, the electric cylinder body 5422 is fixed to one surface of a steering wheel mounting plate 59, while the drive steering wheel 54 is mounted on the other opposite surface of the steering wheel mounting plate 59. In this way, the power of the electric cylinder body 5422 is transmitted to the drive steering wheel 54 through the steering wheel mounting plate 59, causing it to contact the ground.

[0039] Further preferably, the walking device 50 further includes a side plate 51, on which a first support wall 514 and a second support wall 512 located below the first support wall 514 are provided; a guide rod 516 is provided between the first support wall 514 and the second support wall 512, the guide rod 516 passing through the steering wheel mounting plate 58, so that the steering wheel mounting plate 58 is slidably disposed between the first support wall 514 and the second support wall 512; a compression spring 53 sleeved on the guide rod 516 is provided between the steering wheel mounting plate 58 and the second support wall 512. By providing the compression spring 53, the vibration of the drive steering wheel 54 when rolling relative to the ground is reduced. For example, if the intelligent transfer vehicle 100 walks bumpily due to uneven road surface, which may damage the equipment, the compression spring 53 can play a shock absorption role, thereby making the walking process more stable and smooth.

[0040] In the above embodiments, the base 12 of the frame 10 can be constructed by connecting multiple, for example, four, profiles of suitable length, such as aluminum alloy profiles or stainless steel profiles. Considering that the entire intelligent transfer vehicle 100 needs to transfer heavy current transformers or circuit breakers inside the electrical switch cabinet, it needs to have a certain load capacity. Therefore, the base 12 needs to have sufficient structural strength, so it is preferable to use steel, such as stainless steel, to form the base 12. Multiple profiles can be fixed to each other in an appropriate way, such as riveting, threaded connection, or welding. In another embodiment, the frame 10 adopts a square tube integral welded structure, which ensures the strength of the entire vehicle body and meets the load-bearing requirements.
