Since the rails in the turning section of the railway are laid at an inclined angle, the monorail traveling device will still roll over when it travels along a single rail to the turning section of the railway.

[0008] Optionally, an end cap is provided at one end of the positioning column passing through the through slot or the through hole, and the size of the end cap is larger than the size of the through slot or the through hole, so as to limit the limit baffle from separating from the positioning column.

Compared with the setting method in which the electromagnet is fixed to the vehicle body and is always close to the top surface of the rail head, this can avoid the problem of increased energy consumption and affected walking speed of the monorail traveling device caused by the residual magnetic force of the electromagnet for a period of time due to the electromagnet still being close to the rail after power failure. In addition, the electromagnet restored to its initial position away from the top surface of the rail head can also avoid the electromagnet and the raised rail from colliding due to the height difference at the joint of the rails in the straight section of the rail, thereby affecting the walking operation of the monorail traveling device.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The technical solutions disclosed in various embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Please refer to Figures 1 to 3 As shown, the embodiment of the utility model discloses a magnetic assembly for a monorail walking device, and the disclosed magnetic assembly includes a mounting seat 164, an electromagnet 160, a guide column 161 and a spring 163; the mounting seat 164 is provided with a wiring hole 168 and a guide through hole adapted to the guide column 161; the wiring hole 168 is used for the wire of the electromagnet 160 to pass through the mounting seat 164 and connect with the circuit board in the vehicle body 100; one end of the guide column 161 passes through the guide through hole and is connected to the electromagnet 160 through a detachable structure such as a thread or a snap, and the other end of the guide column 161 is fixedly provided with a limit baffle 162, and the limit baffle 162 and the electromagnet 160 are respectively located on opposite sides of the mounting seat 164; the spring 163 is sleeved on the guide column 161 and is located between the limit baffle 162 and the mounting seat 164, and the two ends of the spring 163 respectively resist the limit baffle 162 and the mounting seat 164.

[0030] When the monorail traveling device runs along a single rail 200 and tilts at a turning section of the rail, the electromagnet 160 can be controlled to be energized to generate magnetic force, so that the electromagnet 160 is close to the top surface of the rail head of the rail 200 through the magnetic force, and the force of the vehicle body 100 adhering to the rail 200 is effectively increased, thereby solving the problem that the existing monorail traveling device is still prone to overturning when running on a turning section of the rail; at the same time, the spring 163 will undergo elastic deformation under the action of the magnetic force between the electromagnet 160 and the rail 200, so that the electromagnet 160 can be quickly reset by the elastic restoring force of the spring 163 when the power is cut off and the electromagnet 160 stops working.

[0031] When the monorail travel device runs along a single rail 200 from the turning section of the rail to the straight section and recovers to the horizontal level, the electromagnet 160 can be controlled to be powered off and stop working, eliminating the magnetic force between the electromagnet 160 and the rail 200, so that the electromagnet 160 can quickly return to the initial position away from the top surface of the rail head under the elastic restoring force of the spring 163. Compared with the setting method in which the electromagnet 160 is fixed to the vehicle body 100 and is always close to the top surface of the rail head of the rail 200, it can avoid the problem of increased energy consumption and affected walking speed of the monorail travel device caused by the residual magnetic force of the electromagnet 160 for a period of time due to the electromagnet 160 being still close to the rail 200 after power failure; and the electromagnet 160 restored to the initial position is away from the top surface of the rail head of the rail 200, which can also avoid the electromagnet 160 and the elevated rail 200 from tripping due to the height difference at the joint of the rail 200 in the straight section of the rail, thereby affecting the walking operation of the monorail travel device.

[0032] It is easy to understand that the magnetic force generated by the electromagnet 160 when it is working can also prevent the monorail traveling device from vibrating up and down when traveling along a single steel rail, thereby helping to improve the walking stability and detection structure accuracy of the monorail traveling device when it is equipped with detection equipment such as cameras or lasers for inspection operations.

[0033] At the same time, in the process of the monorail walking device walking along the rail 200, in order to avoid the problem of the electromagnet 160 and the mounting seat 164 rotating relative to each other due to vibration and other reasons, causing the wire of the electromagnet 160 to be worn. Figure 1 As shown, a positioning column 165 can also be set on the side of the mounting seat 164 facing the limit baffle 162, and the positioning column 165 is parallel to the guide column 161; the limit baffle 162 is provided with a through groove or a through hole adapted to the positioning column 165, and the positioning column 165 passes through the through groove or the through hole, so that the relative rotation of the electromagnet 160 and the mounting seat 164 can be effectively prevented through the positioning cooperation between the positioning column 165 and the limit baffle 162, thereby avoiding the problem of wire wear of the electromagnet 160.

[0034] Preferably, an end cap 166 is provided at one end of the positioning column 165 passing through the through slot or through hole of the limit baffle 162, and the size of the end cap 166 is larger than the size of the through slot or through hole, so that the positioning column 165 forms a limiting fit with the limit baffle 162 of the guide column 161 in the vertical direction through the end cap 166, which can prevent the electromagnet 160 from moving excessively upward and causing the limit baffle 162 to separate from the positioning column 165.

[0035] In this embodiment, an oil-free bushing 167 can be fixedly installed in the guide hole of the mounting seat 164, so that the guide column 161 cooperates with the guide hole of the mounting seat 164 through the oil-free bushing 167. The oil-free bushing 167 can play a good guiding and friction reducing role for the up and down sliding of the guide column 161, thereby ensuring the smooth movement of the electromagnet 160. Compared with linear bearings, the oil-free bushing 167 has the advantages of simple structure, high strength and little or no need to add lubricating oil.

[0036] In order to realize automatic detection of whether the monorail walking device is tilted, the disclosed magnetic assembly may further include an inclination sensor, and the inclination sensor is connected to the electromagnet 160 through a corresponding control circuit; when the inclination sensor detects and generates a tilt signal, the control circuit controls the electromagnet 160 to work and generate magnetic force according to the received tilt signal; when the inclination sensor does not detect and generate a tilt signal, the control circuit controls the electromagnet 160 to stop working.

[0037] Example 2

[0038] Based on the magnetic assembly disclosed in Example 1, this embodiment discloses a monorail walking device, such as Figure 2 and Figure 3 As shown, the disclosed monorail traveling device includes a car body 100 and the magnetic assembly described in the embodiment; wherein, the car body 100 is provided with an opening adapted to the electromagnet 160 at the bottom facing the rail 200, the mounting seat 164 is detachably provided on the upper end surface of the opening by means of bolts and other structures, and the electromagnet 160 is located on the lower end surface of the opening, thereby facilitating the assembly and disassembly of the magnetic assembly and the car body 100, and facilitating the magnetic assembly to complete the corresponding action.

[0039] Typically, the vehicle body 100 is provided with a walking mechanism, which includes a driving wheel 130 arranged at the front end area of ​​the bottom of the vehicle body 100 and a driven wheel 140 arranged at the rear end area of ​​the bottom of the vehicle body 100. The driving wheel 130 adopts a wheel motor structure to provide walking power for the vehicle body 100, and cooperates with the driven wheel 140 to realize the walking function of the vehicle body. It belongs to the prior art and will not be described in detail in this embodiment; and, in order to enable the magnetic component to play a better role, the electromagnet 160 is located on the center line of the driving wheel 130 and the driven wheel 140, and is located between the driven wheel 140 and the driving wheel 130, thereby ensuring that the magnetic force generated by the electromagnet 160 can act on the vehicle body 100 in a balanced manner.

[0040] At the same time, the shapes of the driving wheel 130 and the driven wheel 140 can be set to be roller-shaped, and as Figure 4As shown, an annular groove 1401 extending along the circumference of the driven wheel 140 is opened in the middle position of the driven wheel 140. The annular groove 1401 structure allows the driven wheel 140 to form a two-point matching walking structure with the arc structure on the top surface of the rail head of the rail 200, thereby effectively avoiding the left and right shaking of the monorail walking device and improving the stability of walking along the single rail 200.

[0041] In the monorail running device disclosed in this embodiment, a driven wheel mounting support 141 is provided at the bottom of the vehicle body 100, so as to facilitate the installation of the driven wheel 140; wherein the driven wheel mounting support 141 can be designed as a frame structure, but in order to prevent dust and other debris from entering the interior of the vehicle body 100 through the driven wheel mounting support 141 and causing damage to the circuit board and other components, as shown in FIG. Figure 5 As shown, the driven wheel mounting support 141 is preferably designed as a semi-cylindrical protective cover structure adapted to the driven wheel 140, and a rotating shaft is set on the end faces of both ends of the driven wheel mounting support 141, so that the driven wheel 140 is assembled on the rotating shaft through bearings, that is, the inner ring of the bearing is fixed on the rotating shaft 142, and the driven wheel 140 is sleeved and fixed on the outer ring of the bearing.

[0042] In order to prevent the end surface of the driven wheel 140 from rubbing against the driven wheel mounting support 141 at both ends of the rotating shaft 142, as shown in FIG. Figure 5 As shown, the driven wheel 140 mounting seat is provided with an annular boss 143 distributed along the circumference of the rotating shaft 142, so that the annular boss 143 abuts against the inner ring of the bearing, so that the end surface of the driven wheel 140 maintains a certain distance from the driven wheel mounting support 141 at both ends of the rotating shaft 142, avoiding frictional contact between the two.

[0043] It should be noted that a circuit board is provided inside the vehicle body 100, and the circuit board is designed with a control circuit and a power supply circuit for controlling the electromagnet 160. The corresponding circuit adopts the existing circuit design, and the above embodiment will not describe the circuit structure of the circuit board in detail.

[0044] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
