Description

Technical Field

[0001] The utility model relates to the technical field of pantographs, in particular to a monitoring device for overall dynamic monitoring of a pantograph. Background Art

[0002] The power source of high-speed trains is obtained through the sliding contact between the pantograph and the contact network. Therefore, the relationship between the pantograph and the contact network affects the running safety of the train. Due to the presence of uneven parts such as wire switches and anchor joints on the contact network, the contact network may drill under the pantograph head during the operation of the high-speed train, causing damage to the contact network or the pantograph, and then a pantograph accident may occur.

[0003] The existing monitoring device for the overall dynamic monitoring of the pantograph cannot perform dynamic monitoring according to the changing angle of the pantograph, resulting in that once the pantograph is in the lowered state and the insulation performance of the supporting insulator is normal, the bow angle of the pantograph is close to the roof of the train, and the insulation strength between the two is relatively weak, resulting in the equipment being unable to monitor and adjust it in time. At the same time, when the equipment is in use, the pantograph is prone to vibration when it contacts the contact network, which reduces the stability of the equipment. The pantograph is easily affected by the comprehensive environment, and the insulation performance is further reduced. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a monitoring device for overall dynamic monitoring of a pantograph, which has the advantages of dynamic monitoring and stability, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a monitoring device for overall dynamic monitoring of a pantograph, comprising a base, a bow lifting mechanism fixedly installed on the top of the base, a controller fixedly installed on the top of the bow lifting mechanism, a block fixedly installed on the top of the base, an active rod fixedly installed on the outer wall of the block, a lower arm rotatably connected to the outer wall of the active rod, an upper arm rotatably connected to the inner wall of the lower arm, a rotating rod rotatably connected to the outer wall of the upper arm, a support rod fixedly installed on the outer wall of the rotating rod, a long rod fixedly installed on the top of the support rod, a slide plate provided on the top of the long rod, a round block fixedly installed on the inner wall of the support rod, a magnet provided on the inner wall of the round block, a round rod provided on the bottom of the round block, a guide rod rotatably connected to the outer wall of the base, and a monitoring device provided on the top of the base.

[0006] As a preferred technical solution of the utility model: the output end of the controller is electrically connected to the input end of the lifting bow mechanism, and the outer wall of the slide plate is trapezoidal in shape.

[0007] As a preferred technical solution of the utility model: the monitoring device includes a resistor block, the outer wall of the resistor block is slidably overlapped with a pointer, the outer wall of the lower arm is fixedly connected to the pointer, and the outer wall of the resistor block is fixedly connected to the outer wall of the block.

[0008] As a preferred technical solution of the utility model: the number of the monitoring devices is three, and the monitoring devices are respectively located at the rotation connection between the active rod and the lower arm, the rotation connection between the lower arm and the upper arm, and the rotation connection between the rotating rod and the upper arm.

[0009] As a preferred technical solution of the utility model: the number of the magnets and the round rods are both two, and the two magnets are respectively clamped on the inner walls of the two round rods, and the N poles of the two magnets are arranged correspondingly.

[0010] As a preferred technical solution of the utility model: the number of the round rods is four, and the four round rods are evenly distributed at the four corners of the bottom of the round block, the two round blocks are respectively located at the two ends of the round rod, and the round block close to the bottom of the round rod forms a sliding sleeve connection with the outer wall of the round rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The monitoring device for overall dynamic monitoring of the pantograph, when the lower arm rotates on the outer wall of the active rod, the lower arm drives the pointer to achieve sliding overlap on the outer wall of the monitoring device, and is electrically connected to the pointer through the resistance block. The lower arm is used to drive the pointer to rotate, so that the positions of the resistance block and the pointer are changed, thereby changing the current and resistance formed between the pointer and the resistance block, and then calculating the change angle between the lower arm and the block through the change value of the current, so that the angle changes during the angular movement of the equipment, thereby achieving dynamic monitoring.

[0013] 2. The monitoring device for overall dynamic monitoring of the pantograph, when the slide plate comes into contact with the contact network, the equipment vibrates. The contact between the slide plate and the contact network is unstable, so the slide plate vibrates through the long rod. The magnets at the bottom of the long rod are respectively clamped on the inner wall of the round block. The corresponding surfaces of the two magnets are of the same polarity. The repulsion between the two magnets of the same polarity is utilized to make the two magnets produce shock absorption, thereby increasing the stability of the equipment.

Based on the embodiments in 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.

[0023] In the above structure, the guide rod 5 is installed to provide auxiliary support for the rotation of the lower arm 6 and the monitoring device 7, thereby increasing the operating stability of the equipment.

[0024] In a preferred embodiment: the output end of the controller 3 is electrically connected to the input end of the bow lifting mechanism 2, and the outer wall of the slide plate 9 is in a trapezoidal shape.

[0025] In the above structure, the slide plate 9 slides on the guide rail. Therefore, when the high-speed rail receives a bow raising command, the long rod 11 can slide outward along the guide rail, thereby fully extending to contact the contact network. When the high-speed rail receives a bow lowering command, the bow raising and lowering mechanism 2 drives the rotating rod 16 through the upper arm 8 to achieve rotation and lifting. The long rod 11 can slide inward along the guide rail, thereby shrinking away from the contact network.

[0026] In a preferred embodiment: the monitoring device 7 includes a resistor block 701, the outer wall of the resistor block 701 is slidably overlapped with a pointer 702, the outer wall of the lower arm 6 is fixedly connected to the pointer 702, and the outer wall of the resistor block 701 is fixedly connected to the outer wall of the block 4.

[0027] In the above structure, when the lower arm 6 rotates on the outer wall of the active rod 15, the lower arm 6 drives the pointer 702 to achieve sliding overlap on the outer wall of the monitoring device 7, and is electrically connected to the pointer 702 through the resistor block 701. The lower arm 6 drives the pointer 702 to rotate, so that the positions of the resistor block 701 and the pointer 702 are changed, thereby changing the current and resistance formed between the pointer 702 and the resistor block 701, and then calculating the change angle between the lower arm 6 and the block 4 through the change value of the current.

[0028] In a preferred embodiment, there are three monitoring devices 7 , and the monitoring devices 7 are respectively located at the rotation connection between the active rod 15 and the lower arm 6 , the rotation connection between the lower arm 6 and the upper arm 8 , and the rotation connection between the rotating rod 16 and the upper arm 8 .

[0029] In the above structure, by rotating between the lower arm 6 and the active rod 15, rotating between the upper arm 8 and the lower arm 6, and rotating between the upper arm 8 and the rotating rod 16, the angle of the equipment changes during the angular movement, thereby realizing dynamic monitoring to determine whether the outer wall of the slide plate 9 is in contact with the contact network.

[0030] In a preferred embodiment, the number of the magnets 13 and the number of the round rods 14 are both two, and the two magnets 13 are respectively clamped on the inner walls of the two round rods 14, and the N poles of the two magnets 13 are arranged correspondingly.

[0031] In the above structure, when the device is installed on the top of the train, when the slide plate 9 is used to make contact with the contact network, the device vibrates, and the contact between the slide plate 9 and the contact network is unstable, so that the slide plate 9 vibrates through the long rod 11, and the magnets 13 at the bottom of the long rod 11 are respectively clamped on the inner wall of the round block 12. The corresponding surfaces of the two magnets 13 are of the same sex. The repulsion between the two magnets 13 is used to make the two magnets 13 produce shock absorption, thereby increasing the stability of the equipment.

[0032] In a preferred embodiment, there are four round rods 14 , which are evenly distributed at the four corners of the bottom of the round block 12 . Two round blocks 12 are respectively located at both ends of the round rod 14 , and the round block 12 close to the bottom of the round rod 14 forms a sliding sleeve connection with the outer wall of the round rod 14 .

[0033] In the above structure, the four round rods 14 are evenly distributed at the four corners of the bottom of the round block 12, so that the round rods 14 can limit the round block 12, thereby preventing the round block 12 from shifting in position during the shock absorption process, thereby increasing the stability of the device.

[0034] Working principle: By installing the device on the top of the train and sliding the slide plate 9 on the guide rail, when the high-speed rail receives the bow raising command, the long rod 11 can slide outward along the guide rail, so as to fully extend to contact the contact network. When the high-speed rail receives the bow lowering command, the bow raising and lowering mechanism 2 drives the rotating rod 16 through the upper arm 8 to realize rotation and lifting. The long rod 11 can slide inward along the guide rail, so as to shrink away from the contact network. When the lower arm 6 rotates on the outer wall of the active rod 15, the lower arm 6 drives the pointer 702 to achieve sliding overlap on the outer wall of the monitoring device 7, and is electrically connected to the pointer 702 through the resistor block 701. The lower arm 6 drives the pointer 702 to rotate, so that the positions of the resistor block 701 and the pointer 702 are changed, thereby making the pointer The current and resistance formed between 702 and the resistor block 701 change, and then the change angle between the lower arm 6 and the block 4 is calculated through the change value of the current, so that the angle changes during the angular movement of the equipment, and then dynamic monitoring is realized to determine whether the outer wall of the slide plate 9 is in contact with the contact network. When the equipment is installed on the top of the train, when the slide plate 9 is in contact with the contact network, the equipment vibrates, and the contact between the slide plate 9 and the contact network is unstable, so that the slide plate 9 vibrates through the long rod 11, and the magnets 13 at the bottom of the long rod 11 are respectively clamped on the inner wall of the round block 12. The corresponding surfaces of the two magnets 13 are of the same sex. The same-sex repulsion between the two magnets 13 is used to make the two magnets 13 produce shock absorption, thereby increasing the stability of the equipment.
