Description

Technical Field

[0001] The utility model relates to the technical field of a mechanical arm base, in particular to a vertical arm lifting type mechanical arm. Background Art

[0002] Vertical arm lift (also called vertical lifting platform or lift) plays an important role in baggage handling. The following are its main functions and advantages: lifting and lowering luggage, saving manpower, adapting to the needs of different heights, improving work efficiency, versatility and other characteristics, which play an important role in baggage handling.

[0003] However, in order to increase the storage coverage space of a single robotic arm, the vertical arm lifting arm for luggage storage and transportation is often provided with a mobile structure at the bottom to enable the entire device to move. However, due to the large or small weight of the luggage, when carrying luggage that is too heavy, it is easy to cause the center of gravity at the bottom of the device to shift, causing the device to tilt and topple over. For this reason, we provide a vertical arm lifting robotic arm to solve the above problem. Utility Model Content

[0016] 1. The utility model cooperates between the load-bearing plate, the protective shell, the motor, the water pump, the counterweight box and the extension mechanism. The load-bearing plate constitutes the main load-bearing and supporting function of the bottom of the equipment.

A protective shell 7 is fixedly connected to the outer surface of the load-bearing plate 1. The load-bearing plate 1 constitutes the main load-bearing and supporting function of the bottom of the equipment. The protective shell 7 is used to protect the components below and to install the mechanical arm body. When the mechanical arm is carrying heavy luggage, it will detect the weight of the luggage hoisted by the mechanical arm. When the weight exceeds the limit, a signal will be sent to the central console. After receiving the signal, the central console will suspend the operation of the robot arm and start the motor 4 and the water pump 3. The motor 4 can drive the extension mechanism 6 to extend the comprehensive contact surface between the bottom of the robot and the ground. The water pump 3 can transport the balancing liquid in the balancing box 2 close to the inside of the luggage to the balancing box 2 far away from the luggage, so that the center of the equipment is level when it is connected with the luggage, thereby reducing the bottom volume of the equipment as a whole while increasing the limit of the luggage weight, thereby solving the problem of the center of gravity shifting at the bottom of the equipment due to excessive luggage, causing the equipment to tilt and tip over.

[0025] A mounting frame 1 8 and a mounting frame 2 9 are installed on the bottom surface of the load-bearing plate 1. The outer surface of the mounting frame 1 8 is fixedly connected to the outer surface of the motor 4, and the outer surface of the mounting frame 2 9 is fixedly connected to the outer surface of the water pump 3. The mounting frame 1 8 and the mounting frame 2 9 can install the motor 4 and the water pump 3 under the load-bearing plate 1 so that the motor 4 and the water pump 3 are as close to the ground as possible. Since the overall weight of the motor 4 and the water pump 3 is relatively large, the overall top-heavy situation of the equipment can be prevented.

[0026] A water pipe 10 is installed on the inner side of the counterweight box 2, and the outer surface of the water pipe 10 is fixedly connected to the inner side of the load-bearing plate 1. The water pipe 10 is fixedly connected to the output end of the water pump 3 at the end away from the counterweight box 2. The load-bearing plate 1 can provide a fixing function for the water pipe 10. The water pump 3 can freely control the counterweight liquid inside the two counterweight boxes 2 through the water pipe 10, so that it can stabilize the center of gravity of the equipment in real time.

[0027] The extension mechanism 6 includes a telescopic arm 601, the outer surface of the telescopic arm 601 is slidably connected to the inner wall of the sleeve 5, the outer surface of the telescopic arm 601 is provided with teeth 602, one end of the telescopic arm 601 is rotatably connected to a wheel frame 603, a roller 604 is installed inside the wheel frame 603, the telescopic arm 601 is located on the bottom surface of the wheel frame 603 and a bearing is installed, the bearing is sleeved on the wheel frame 603, so that the wheel frame 603 is more flexible when rotating and can also be more convenient to change direction, the inner wall of the sleeve 5 is provided with an I-shaped groove, the outside of the telescopic arm 601 is provided with an I-shaped plate, the I-shaped plate slides on the I-shaped groove, so that the telescopic arm 601 will not be offset or tilted when moving in the sleeve 5.

[0028] The inner wall of the sleeve 5 is rotatably connected to several gear columns 11, and the outer surface of the gear column 11 is meshed with the outer surface of the teeth 602. When the telescopic arm 601 moves, the teeth 602 can drive the gear column 11 to rotate. When the gear column 11 rotates, it can drive the other telescopic arm 601 to move in the opposite direction.

[0029] The output end of the motor 4 is fixedly connected to a rotating rod 14, and the outer surface of the rotating rod 14 is fixedly connected to a gear 2 15. The motor 4 can drive the rotating rod 14 to rotate. A bearing is installed inside the load-bearing plate 1, and the bearing is sleeved on the outer surface of the rotating rod 14, so that the rotating rod 14 is more flexible when rotating, thereby facilitating the motor 4 to drive the gear 2 15 to rotate through the rotating rod 14.

[0030] The outer surface of one of the gear columns 11 is fixedly connected to a transmission rod 12, the outer surface of the transmission rod 12 is fixedly connected to a gear 13, the gear 13 is meshed with a transmission chain 16, the inner surface of the transmission chain 16 and the outer surface of the gear 2 15 are meshed with each other, and when the gear 2 15 rotates, the transmission chain 16 can drive the gear 2 15 and the transmission rod 12 to rotate, thereby enabling the motor 4 to extend or retract simultaneously by driving the two integral extension mechanisms 6.

[0031] Working principle: When the luggage is too heavy, the weight detector on the mechanical arm can send the excess weight data to the central console, and then the central console will control the water pump 3. The water pump 3 can transport the balancing liquid in the balancing box 2 close to the luggage to the balancing box 2 far away from the luggage, so that the center of the equipment is level when carrying the luggage. At the same time, when the mechanical arm is extended in a single direction in the vertical and horizontal directions, the central console will start the motor 4. The motor 4 can drive the transmission chain 16 and the gear 2 15 through the rotating rod 14 and the gear 1 13. The gear 2 15 can drive the gear column 11 to rotate through the transmission rod 12. The gear column 11 can drive the telescopic arm 601 to move in two opposite directions through the teeth 602, so that the center of gravity of the equipment can remain stable and not shift.
