[0027] Please refer to Figure 1 A walking cart provided by the embodiment of the application comprises a frame 8, walking wheels 9 and a walking motor position detection device, the walking wheels 9 are rotatably installed at the end of the frame 8, a mounting bracket 2 is fixed to the outer side of the frame 8, and the output shaft of the walking motor 1 is in transmission connection with the walking wheels 9.
[0028] Specifically, the overall contour shape of the frame 8 is a structure similar to a cuboid, and the frame 8 can be provided with a rotating mounting structure at the four corners, so that the walking wheels 9 can be rotatably installed at the four corners of the frame 8, that is, one set of walking wheels 9 is installed at each end of the frame 8, so that the frame 8 can be moved by the four sets of walking wheels 9, and the walking cart can be moved stably.
[0029] The mounting bracket 2 can be welded on the frame 8, and in the embodiment, one mounting bracket 2 is fixed at each corner of the frame 8, so that each mounting bracket 2 can correspond to one set of walking wheels 9, and the walking motor 1 is fixed on the mounting bracket 2, so that the walking motor 1 can be in driving connection with the walking wheels 9, so that the walking motor 1 can drive the walking wheels 9 to move the frame 8, and the position of the walking motor 1 can be detected in real time by the walking motor position detection device, so as to prevent the safety risk caused by continuing to start the walking motor 1 after the walking motor 1 loosens.
[0030] Please refer to Figure 1 In some embodiments, the walking cart can further comprise a buffer 10, and the buffer 10 is made of rubber material and has good elasticity and buffering performance.
[0031] Specifically, the buffer 10 is in the shape of a cylinder, and the opposite two end faces of the frame 8 are respectively provided with the buffer 10 along the moving direction of the walking trolley, more specifically, the end faces of the frame 8 at the four corners are respectively provided with the buffer 10 towards the moving direction of the walking trolley, and the buffer 10 can buffer the impact that the frame 8 may suffer during movement, thereby protecting the walking trolley.
[0032] Please refer to Figure 1 and Figure 2 In some embodiments, the walking motor position detection device can include a walking motor 1, a mounting bracket 2, and a plurality of normally closed inductive switches 4.
[0033] Specifically, the mounting bracket 2 has a mounting surface on which the walking motor 1 can be fixed, and a plurality of limiting plates 3 are provided on the mounting surface, each of which is perpendicular to the mounting surface. The plurality of limiting plates 3 are located around the walking motor 1, or in other words, the plurality of limiting plates 3 are arranged around the walking motor 1, and the plurality of normally closed inductive switches 4 are arranged on the plurality of limiting plates 3 respectively, so that each normally closed inductive switch 4 is arranged towards the walking motor 1, and each normally closed inductive switch 4 can be connected in series in the power supply circuit of the walking motor 1.
[0034] Each normally closed inductive switch 4 is a normally closed inductive switch 4. When the walking motor 1 is loosened due to long-term use and shakes during startup, the walking motor 1 will approach or directly contact a normally closed inductive switch 4 on one side during shaking, and trigger the normally closed inductive switch 4 to act. After the normally closed inductive switch 4 is triggered, the power supply circuit is disconnected, thereby rapidly cutting off the power supply of the walking motor 1, effectively preventing the risk that may be caused by the continuous startup of the walking motor 1, especially avoiding the serious consequences of the breakage of the connecting shaft of the walking motor 1 and the walking wheel 9 due to excessive stress.
[0035] Please refer to Figure 2 In some embodiments, the limiting plate 3 is in the shape of a long plate structure, and the limiting plate 3 is perpendicular to the mounting surface of the mounting bracket 2 along the length direction of the limiting plate 3, and a plurality of normally closed inductive switches 4 can be arranged on each limiting plate 3, and the plurality of normally closed inductive switches 4 are arranged in series along the length direction of the limiting plate 3, thereby enabling more detailed and comprehensive detection of the shaking of the walking motor 1.
[0036] When the walking motor 1 shakes or deviates during operation, multiple normally closed inductive switches 4 can be triggered in turn to provide accurate information about the degree and direction of shaking, and this design also helps to realize the function of hierarchical alarm or control. For example, when the walking motor 1 only shakes slightly, only part of the normally closed inductive switches 4 may be triggered; when the shaking exceeds a certain threshold, more normally closed inductive switches 4 are triggered, and higher-level safety measures or shutdown protection can be started to prevent equipment damage or accidents.
[0037] Please refer to Figure 2 In some embodiments, the walking motor position detection device can also include multiple inductive pieces 5, which can be arranged at different positions of the walking motor 1, and the multiple inductive pieces 5 correspond to the multiple normally closed inductive switches 4 respectively.
[0038] Specifically, the inductive piece 5 is also a long plate structure, which can be welded on the walking motor 1, and the multiple inductive pieces 5 are located on opposite sides of the walking motor 1 respectively. Each inductive piece 5 corresponds to at least one normally closed inductive switch 4, that is, each inductive piece 5 can correspond to one normally closed inductive switch 4, or each inductive piece 5 corresponds to multiple normally closed inductive switches 4.
[0039] When the walking motor 1 shakes, the inductive piece 5 will move and approach the corresponding normally closed inductive switch 4, and the approach action can be quickly captured by the normally closed inductive switch 4 to trigger the corresponding signal or action. This design not only improves the sensitivity of shaking detection, but also enables a faster response to shaking events and takes appropriate measures.
[0040] In addition, the distributed layout of the multiple inductive pieces 5 and the normally closed inductive switches 4 also enhances reliability and stability. Even if part of the inductive pieces 5 or the normally closed inductive switches 4 fail for some reason, the other normal inductive pieces 5 and the normally closed inductive switches 4 can still continue to work, ensuring that the detection function is not affected.
[0041] Please refer to Figure 2 In some embodiments, the walking motor position detection device can also include a U-shaped plate 6, which can be fixed on the walking motor 1. Specifically, the U-shaped plate 6 can be fixed on the walking motor 1 in the horizontal direction, so that the open end of the U-shaped plate 6 can face one side of the walking motor 1. When the inductive piece 5 is fixed on the open end of the U-shaped plate 6 in the vertical direction, the inductive piece 5 can be arranged opposite to the limiting plate 3, so that the inductive piece 5 can be arranged opposite to the normally closed inductive switch 4. By arranging the U-shaped plate 6 on the walking motor 1, the inductive piece 5 can be conveniently installed.
[0042] Please refer to Figure 2In some embodiments, the distance between the inductor 5 and the normally closed inductive switch 4 ranges from greater than or equal to 5 cm to less than or equal to 10 cm.
[0043] Specifically, when the distance between the inductor 5 and the normally closed inductive switch 4 is within the range of 5 cm to 10 cm, the normally closed inductive switch 4 can sensitively detect the approaching action of the inductor 5, and can ensure that the slight changes in the shaking of the walking motor 1 can be captured in time. At the same time, setting the lower limit of the distance to 5 cm can ensure that under normal operating conditions, the inductor 5 will not accidentally contact the normally closed inductive switch 4, thereby avoiding system instability or false alarms caused by false actions.
[0044] Please refer to Figure 2 In some embodiments, the limiting plate 3 can be provided with a reinforcing plate 7, and the reinforcing plate 7 is in the shape of a triangular plate and can be located at the connection between the limiting plate 3 and the mounting bracket 2.
[0045] Specifically, the reinforcing plate 7 is provided on the side of the limiting plate 3 away from the walking motor 1, and the adjacent two sides of the reinforcing plate 7 can be connected with the limiting plate 3 and the mounting bracket 2 respectively. The reinforcing plate 7 can increase the structural strength of the limiting plate 3, so that the limiting plate 3 can effectively limit the movement range of the walking motor 1, and prevent the walking motor 1 from falling off the mounting bracket 2 due to excessive shaking.
[0046] In some embodiments, the normally closed inductive switch 4 is one of an electromagnetic inductive switch and a capacitive inductive switch. The electromagnetic inductive switch can achieve the closing and opening of the switch through the change of the magnetic field, and can well cooperate with the inductor 5. The capacitive inductive switch has the characteristics of high sensitivity, good stability, and strong reliability, and has the advantages of waterproof and strong anti-interference ability, so that the walking motor position detection device can more accurately detect the shaking condition of the walking motor 1.
[0047] In some embodiments, the walking motor position detection device further comprises an alarm, and the alarm is connected in parallel in the power supply circuit and is connected in series with a normally open inductive switch.
[0048] Specifically, the alarm can be fixed on the vehicle frame 8 at a position that can be easily observed by the operator. The alarm can be connected in parallel in the power supply circuit of the walking motor 1, so that the power supply for the walking motor 1 can also power the alarm. In addition, the alarm can be connected in series with a normally open inductive switch, which can be provided on the limiting plate 3.
[0049] When the walking motor 1 shakes, the normally open inductive switch is triggered and closed, so that the current passes through the alarm, and the alarm can issue a warning to prompt the operator that the walking motor 1 has loosened and needs to be repaired or replaced in time.
[0050] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
