Ordinal words such as "first" and "second" are referred to herein merely as labels, and do not have any other meaning, e.g., a particular order, etc.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the invention is not limited to the specific details known to a person skilled in the art. The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

The utility model provides an electricity-taking device. Referring to fig. 1 to 4, the power-taking device is used for a rail vehicle. The rail vehicle is a straddle type monorail system rail vehicle. The railway vehicle comprises a bogie and a vehicle body. The bogie comprises a bogie member 140. The bogie member 140 is connected to the vehicle body. The straddle monorail system comprises a track beam 120 and a contact rail 110. The bogie is disposed on the track beam 120 such that the track beam 120 supports the railway vehicle. The contact rail 110 is located at a side of a portion of the rail beam 120 in a width direction (left-right direction of fig. 2) of the rail beam 120, and is connected to the rail beam 120.

Referring to fig. 1 to 8, the power-taking device includes an insulating support 130. The insulating support 130 includes an insulating body 131. The insulating body 131 is an insulating material. For example, the insulating body 131 is a rubber member, a nylon member, or an SMC (Sheet molding compound) composite member. Thus, the insulating body 131 cannot conduct electricity.

Referring back to fig. 2, the insulating support 130 is located at a side of the track beam 120 in a width direction of the track beam 120. The insulating bracket 130 is fixedly connected to the bogie member 140.

As shown in fig. 7, a first metal sleeve 133 is embedded in one end of the insulating body 131. The first metal sleeve 133 is provided with an internal thread. Thereby, the first metal cover 133 can increase the strength of the insulating support 130.

As shown in fig. 1 to 8, the current-taking device further includes a guiding current-taking wheel 150 and a wheel axle 200. The axle 200 and the guide pick-up wheel 150 are both conductive elements. In this way, the directional pick-up wheel 150 may be conductive. The guided pick-up wheel 150 includes a wheel body 151. The wheel body 151 has a disc structure. The axial direction of the wheel body 151 and the axial direction of the axle 200 are both parallel to the height direction of the bogie member 140 (i.e., the height direction of the track beam 120, i.e., the up-down direction of fig. 2). The wheel body 151 is located at a side of the contact rail 110 in a width direction of the rail beam 120.

As shown in fig. 7 and 8, one end of the axle 200 is provided with an external thread. The axle 200 is screwed to the first metal sleeve 133. The take-off guide wheel 150 is rotatably connected to the axle 200 by a later bearing 170. In this way, the directional pick-off wheel 150 may rotate relative to the axle 200.

Referring back to fig. 2, the wheel body 151 is rollably connected to the contact rail 110. Specifically, the outer periphery of the wheel main body 151 abuts against the contact rail 110 from the side of the contact rail 110 in the width direction of the rail beam 120. When the rail vehicle moves in the extending direction of the rail beam 120, the wheel main body 151 rolls on the contact rail 110 to guide the movement of the bogie, and thus the rail vehicle. At the same time, the electrical energy on the contact rail 110 can be conducted to the wheel body 151.

Referring to fig. 8, the power-taking device further includes a slip ring assembly 160. The slip ring assembly 160 includes a stator 162 and a rotor 161. The stator 162 and the rotor 161 are both conductive members. The stator 162 and the rotor 161 are slidably coupled. Thus, when the rotor 161 rotates relative to the stator 162, electric power can flow between the stator 162 and the rotor 161. The stator 162 and the rotor 161 are connected in substantially the same manner as the stator and the rotor of the slip ring assembly of the related art, and thus, will not be described herein.

Further preferably, at least one of the axle 200, the flow guide wheel 150, the stator 162 and the rotor 161 may be a metal piece.

It will be appreciated that in embodiments not shown, at least one of the axle, the directional pick-off wheel, the stator, and the rotor may be made of other electrically conductive materials.

The rotor 161 is fixedly connected to the directional tapping wheel 150. The stator 162 is connected to the hub 200, and is further connected to the insulating support 130 through the hub 200. Thus, when the guide pickup wheel 150 rotates, the rotor 161 rotates together with the guide pickup wheel 150 about the axis of the hub 200, and the rotor 161 rotates about the axis of the hub 200 relative to the stator 162.

The axle 200 may be connected to the power supply circuit of the rail vehicle by a wire 210. In this way, the stator 162 is connected to the power supply circuit of the rail vehicle via the axle 200 in order to supply the electrical consumers of the rail vehicle with power. In this way, when the guide pickup wheel 150 rotates, the electric energy on the contact rail 110 can sequentially flow through the guide pickup wheel 150, the rotor 161, the stator 162 and the axle 200, and then is conducted to the power supply circuit of the rail vehicle, so as to supply power to the rail vehicle.

As shown in fig. 1 to 4, power-taking devices are disposed on both sides of the track beam 120 along the width direction of the track beam 120.

In the present embodiment, the guiding and current-taking wheel 150 is rotatably connected to the bogie member 140 through the wheel axle 200 and the insulating support 130, the guiding and current-taking wheel 150 is configured to be disposed on the lateral side of the track beam 120 in the width direction of the track beam 120, and the outer periphery of the guiding and current-taking wheel 150 is configured to be abutted to the contact rail 110 from the lateral side of the contact rail 110 in the width direction of the track beam 120, so that the guiding and current-taking wheel 150 can be used for guiding the movement of the bogie, and can also guide the electric energy of the contact rail 110 to the power supply circuit of the railway vehicle, and a collector shoe is not required to be disposed, thereby reducing the cost of the railway vehicle; in addition, the guide flow taking wheel 150 is in rolling connection with the contact rail 110, and the friction force and the impact force of the guide flow taking wheel 150 and the contact rail 110 are small, so that the impact between the guide flow taking wheel 150 and the contact rail 110 can be reduced, the abrasion of the guide flow taking wheel 150 and the contact rail 110 is further reduced, and the service lives of the guide flow taking wheel 150 and the contact rail 110 are prolonged; in addition, since the impact between the guide pick-up wheel 150 and the contact rail 110 is small, the pick-up quality can be improved.

Preferably, as shown in fig. 2, 5 and 7, a portion of the outer peripheral surface of the wheel body 151 of the guide pick-up wheel 150 is extended and projected radially outward to constitute a wheel flange 152. The wheel flange 152 is used to lap to the side of the contact rail 110 in the height direction of the bogie member 140. In this way, in the case where the guide pick-up wheel 150 is to be moved in the height direction of the bogie member 140, the contact rail 110 can block the wheel flange 152, thereby blocking the movement of the guide pick-up wheel 150 in the height direction of the bogie member 140, reducing the possibility that the guide pick-up wheel 150 leaves the contact rail 110.

There are two wheel flanges 152. The two wheel flanges 152 are spaced apart in the axial direction of the guide pick-off wheel 150 to form an abutment recess. One wheel flange 152 is located on one side of the contact rail 110 and the other wheel flange 152 is located on the other side of the contact rail 110 along the axis of the leading pick-up wheel 150. The contact rail 110 abuts to the bottom surface of the abutment recess. Thus, wheel flanges 152 are provided on both sides of the contact rail 110 in the axial direction of the guide pick-up wheel 150. This can further reduce the possibility of guiding the pickup wheel 150 away from the contact rail 110.

Further preferably, the wheel flange 152 is located at an end of the wheel body 151 in the axial direction leading to the pick-up wheel 150. This simplifies the structure of the guide pick-up wheel 150.

Referring to fig. 7, a second metal sleeve 134 is embedded in an end of the insulating body 131 away from the first metal sleeve 133. The second metal sleeve 134 is provided with an internal thread. The power-taking device further comprises a buffer assembly 240. The damping assembly 240 may be a prior art shock absorber for a vehicle. One end of the cushion assembly 240 is connected to the bogie member 140 by a bolt 280. The other end of the damping member 240 is threadedly coupled to the second metal shell 134. The buffer assembly 240 can be extended and contracted in the axial direction of the guide pick-up wheel 150. In this way, the buffer assembly 240 can buffer the movement of the bogie member 140 in the case that the bogie member 140 moves up and down, thereby preventing the guide pick-up wheel 150 from being separated from the contact rail 110.

Preferably, the insulating body 131 is embedded with a reinforcement 132. The reinforcing member 132 is a metal member. The first metal cover 133, the second metal cover 134, and the reinforcing member 132 are spaced apart from each other. This can further increase the strength of the insulating support 130. Further preferably, the reinforcement 132 is a metal bushing. This can further improve the strength of the insulating holder 130.

It will be appreciated that in embodiments not shown, where the strength of the insulating body is sufficient, the reinforcing member may not be embedded in the insulating body.

As shown in fig. 5 and other fig. 7, the insulating body 131 has a cylindrical structure. The axial direction of the insulating body 131 is parallel to the axis of the guide pick-up wheel 150. Thus, the structure of the insulating body 131 is simple.

A portion of the outer circumferential surface of the insulation body 131 protrudes radially outward to constitute a serration structure 135. The width of the sawtooth structures 135 is parallel to the axis of the leading pick-off wheel 150. The saw-tooth structure 135 is plural. The plurality of saw-tooth structures 135 are sequentially arranged along the axial direction of the insulation body 131. Accordingly, a creepage distance between the buffer member 240 and the axle 200 can be increased, and an insulation capability between the buffer member 240 and the axle 200 can be further improved.

Preferably, referring to fig. 8, the power taking device further includes a bearing housing assembly 180 and a bearing 170. The inner race of the bearing 170 is fitted over and fixedly coupled to the outer circumferential surface of the wheel shaft 200. The bearing housing assembly 180 includes a flange 181 and a bearing housing 182. The bearing 170 includes a first bearing 171 and a second bearing 172. The guide pickup wheel 150 is sleeved and fixedly connected to an outer ring of the first bearing 171. The flange 181 is disposed around the axle 200. A space is provided between the center hole of the flange 181 and the outer circumferential surface of the hub 200.

The bearing seat 182 is sleeved on the outer circumference of the axle 200. The flange 181 and the bearing housing 182 are respectively located on both sides of a portion of the guide pick-up wheel 150 in the axial direction of the guide pick-up wheel 150. Both the flange 181 and the bearing housing 182 are fixedly connected to the wheel body 151 by bolts 280. A second bearing 172 is disposed within the bearing housing 182. In the axial direction of the guide pick-up wheel 150, a flange 181 is located on the side of the first bearing 171 away from the second bearing 172, for fixing the position of the first bearing 171 in the axial direction of the guide pick-up wheel 150.

In the axial direction of the guide pick-up wheel 150, the rotor 161 is located on the side of the bearing seat 182 away from the flange 181. The rotor 161 includes a rotor body 163. The rotor body 163 is a sleeve-like structure. One end of the rotor body 163 is extended and projected radially outward to constitute a rotor flange 164. The rotor flange 164 abuts and is connected to the bearing housing 182 by bolts 280.

The stator 162 is a sleeve-like structure. The stator 162 is sleeved and connected to the outer circumference of the wheel shaft 200. The rotor body 163 is disposed around the stator 162 and slidably connected to the stator 162.

Preferably, the electricity taking device further comprises a retaining ring 270. The retainer ring 270 is disposed around the axle 200. The hub 200 and the stator 162 are threadedly coupled. The retaining ring 270 is located between the stator 162 and the second bearing 172 in the axial direction of the leading pick-up wheel 150. Accordingly, the stator 162 can block the movement of the retainer ring 270 in the axial direction of the guide pickup wheel 150, and the retainer ring 270 blocks the movement of the second bearing 172 to fix the second bearing 172.

The power-taking device further comprises a bottom cover 260 and a lug 250. The bottom cover 260 includes a bottom cover body 261. The bottom cover body 261 is a sleeve structure. One end of the lower cap body 261 extends and protrudes radially outward to constitute a lower cap flange 262. The end of the rotor 161 away from the rotor flange 164 is sleeved on the outer circumference of the bottom cover flange 262. A gap exists between the bottom cover flange 262 and the rotor 161. The bottom cover body 261 is sleeved on the outer periphery of the wheel axle 200. The bottom cover body 261 is coupled to the axle 200 by bolts 280. Thus, the stator 162 is positioned in the region formed by the bottom cover 260 and the rotor 161, and the stator 162 can be protected.

The lug 250 is fixedly attached to the bottom cover body 261 (e.g., welded). Therefore, when the lug 250 is damaged, the lug 250 can be replaced conveniently.

The lug 250 is connected to the power supply circuit of the rail vehicle by means of a conductor 210. In this way, when the current-drawing guiding wheel 150 rotates, the electric energy on the contact rail 110 can be conducted to the power supply circuit of the railway vehicle through the current-drawing guiding wheel 150, the bearing seat 182, the rotor 161, the stator 162, the axle 200, the bottom cover 260 and the lug 250 in sequence. Furthermore, part of the electrical energy can be conducted to the supply circuit of the rail vehicle via the directional tapping wheel 150, the first bearing 171, the wheel axle 200, the bottom cover 260 and the lug 250 in that order. Part of the electrical energy can be conducted to the supply circuit of the rail vehicle via the guide pick-up wheel 150, the bearing block 182, the second bearing 172, the axle 200, the bottom cover 260 and the lug 250 in sequence.

The power take-off device further comprises a sealing ring and a clamping hoop (not shown). The sealing rings include a first sealing ring 191 and a second sealing ring 192. The clamp includes first clamp and second clamp.

As shown in fig. 8, a portion of the flange 181 extends and projects along the axis of the guide pick-off wheel 150 to form a shoulder 183. The first end of the first sealing ring 191 is sleeved on the periphery of the shoulder 183. A first end of the first seal 191 compresses the outer circumference of the shoulder 183. The second end of the first sealing ring 191 is sleeved on the outer circumference of the axle 200. The first clamp is sleeved on the periphery of the second end of the first sealing ring 191. The first band is used to hold the second end of the first seal 191 tightly to the axle 200. In this way, the first seal 191 can seal the gap between the axle 200 and the shoulder 183.

The first end of the second sealing ring 192 is sleeved on the outer circumference of the end of the rotor 161 far away from the rotor flange 164. The second clamp is sleeved on the periphery of the first end of the second sealing ring 192. The second clip is used to clasp the first end of the second seal 192 to the rotor 161. A second end of the second seal 192 abuts a surface of the bottom cap flange 262 distal from the second bearing 172.
