Description

Technical Field

[0001] This patent relates to the technical field of inspection equipment, and in particular to a track, inspection equipment and inspection system. Background Art

[0002] The suspended track inspection robot is a robot that is suspended on the track by a suspension mechanism and can move back and forth along the track. Different types of functional components can be replaced according to actual needs to achieve corresponding functions.

[0003] Existing inspection robots typically use drag cables or conductor rails for power supply. While drag cables can provide a higher current, they need to follow the robot's movements, placing strict limitations on cable stiffness and track length. Consequently, this approach can only achieve short, linear motions.

[0004] When using a busbar, it's typically necessary to lay a busbar parallel to the track on one side of the inspection robot's track. The inspection robot is equipped with a sliding contact mechanism, which contacts the busbar through this sliding contact mechanism to simultaneously achieve power supply and carrier communication. However, existing technologies for this type of structure require separate mobile tracks and busbar tracks, resulting in high system complexity and a high failure rate. Furthermore, since busbars with this structure are often exposed to the external environment, they are affected by moisture and dust, resulting in poor reliability. Summary of the Invention

[0017] The left guide part and the right guide part are respectively provided with a hoisting groove, which is located on the side opposite to the driving surface and is used for hoisting the rail.

[0018] A further technical solution may be that blocking eaves are provided on both sides of the opening of the cavity along the width direction, and the blocking eaves are used to prevent the sliding contact strip from leaving the cavity;

[0019] An elastic member is also provided in the chamber, the elastic member abuts against the sliding contact bar and pushes the sliding contact bar to move toward the direction of the cavity and abut against the blocking eaves;

[0020] The elastic member is fixed in a contracted state by wax sealing or glue sealing, and can be restored to a relaxed state by removing the wax seal or glue seal after being heated.

[0021] A further technical solution may be that the track further includes two sliding contact bars, which are respectively arranged in the left and right chambers, and the two sliding contact bars are in electrical contact with the inspection equipment connected to the chamber from the left and right sides respectively.

[0022] This patent also discloses a patrol device that can be installed on a track, including:

[0023] A guide wheel capable of being inserted into the cavity of the track;

[0024] A support rod, one end of which is connected to the guide wheel;

[0025] Conductive brushes, which can be connected to the cavity of the track and electrically contact the sliding contact strips arranged in the cavities on the left and right sides of the cavity;

[0026] The inspection platform is connected to the support rod and is suspended on the track through guide wheels and support rods. The conductive brush is connected to the inspection platform to power the inspection platform and provide a communication channel.

[0027] A further technical solution may also be that the guide wheel is carried on a protruding step provided on the track;

[0028] The inspection equipment also includes a driving wheel, which is connected to the inspection platform and abuts against the driving surface of the track. The driving surface is the side of the step opposite to the guide wheel.

Moreover, the single-track structure is simpler, which can significantly reduce the failure rate and save the maintenance cost. More importantly, the single-track structure significantly reduces the space occupation, which can save more space while avoiding possible interference and impact. BRIEF DESCRIPTION OF DRAWINGS

[0054] The technical solution in the embodiment of this patent will be described in detail below in conjunction with the drawings in the embodiment of this patent.

[0055] See also Figure 5 As shown, in some industrial scenarios, rows of electrical control boxes 4 are often installed. These boxes 4 continuously update their monitored readings. In the prior art, there is a need to aggregate the readings from the boxes 4 to a higher-level server for processing. Currently, many factories still rely on manual scheduled meter reading and aggregation, a process prone to errors and inefficient data feedback.

[0056] During the process of intelligent factory transformation, it is necessary to change the data feedback method of the electrical control box 4 from manual feedback to automatic feedback. Due to the complex electromagnetic conditions in some factories or the confidentiality issues involved, wireless data transmission is not allowed. Therefore, it may be necessary to add data output to each independent electrical control box 4. This not only requires adding connecting wiring harnesses and output structures, but also requires the electrical control box 4 itself to be capable of data output. Otherwise, the transformation cost will be very high, or even impossible.

[0057] In view of this, a patrol device 2, such as a patrol robot, can be set up to use the camera set on the robot to obtain data on each electrical control box 4 in turn, and then combined with artificial intelligence technology, the data can be obtained through image text recognition (OCR) and fed back to the server.

[0058] There are many types of inspection robots, such as wheeled ones and those mounted on tracks. In factory environments, wheeled robots require additional navigation and obstacle avoidance features, which is costly. Therefore, track-mounted inspection robots are the preferred option. Furthermore, suspended track-mounted inspection robots are even more preferred.

[0059] In existing technology, inspection robots using track 1 face challenges in power supply and data transmission. As mentioned above, wireless data transmission is difficult in complex electromagnetic environments. Therefore, existing inspection robots generally rely on trailing cables or busbars for power supply. While using a trailing cable allows for higher supply current, the cable must move with the robot, placing strict limitations on cable stiffness and track 1 length. Therefore, this approach generally only allows for short-distance linear motion. For relatively large factories, the feasibility of using a trailing cable is questionable.

[0060] When using a busbar, it is usually necessary to lay a busbar parallel to the track 1 on one side of the inspection robot's track 1. The busbar includes a busbar 16. The inspection robot is provided with a sliding contact mechanism, which contacts the busbar 16 through this sliding contact mechanism to simultaneously achieve power supply and carrier communication. However, this type of structure in the prior art requires the separate provision of a mobile track 1 and a busbar track 1, resulting in a high system complexity and a high failure rate. In addition, since busbars of this type of structure are often exposed to the external environment and are affected by moisture and dust, their reliability is also poor.

[0061] In view of this, the present patent provides a track 1, an inspection platform 24 and an inspection system 3, which have a strong load-bearing capacity, can effectively protect the busbar, and have better reliability.

[0062] Implementation Method 1

[0063] See also Figure 2 As shown, the first embodiment of this patent proposes a track 1. Figure 1 、 Figure 2 and Figure 3 As shown, the track 1 can be applied to inspection equipment 2, such as an inspection platform 24 or specifically an inspection robot, inspection camera, etc. The track 1 includes:

[0064] A left guide portion 11, a right guide portion 12 and a connecting portion 13;

[0065] The left guide portion 11 and the right guide portion 12 are connected together by a connecting portion 13 to form a cavity 14 enclosed between the left guide portion 11, the connecting portion 13 and the right guide portion 12;

[0066] The left guide part 11 and the right guide part 12 each have a chamber 15 communicating with the cavity 14;

[0067] The chamber 15 is used to accommodate the slide strip 16, so that the slide strips 16 in the left and right chambers 15 respectively make electrical contact with the inspection device 2 accessing the cavity 14 from the left and right sides.

[0068] Correspondingly, the first embodiment of the patent also proposes an inspection device 2 capable of being installed on the track 1, comprising:

[0069] A guide wheel 21 capable of accessing the cavity 14 of the track 1; Specifically, the guide wheel 21 can be carried on the protruding step 17 provided on the track 1;

[0070] A support rod 22, one end of the support rod 22 is connected with the guide wheel 21;

[0071] A conductive brush 23 capable of accessing the cavity 14 of the track 1 and making electrical contact with the slide strip 16 provided in the chamber 15 provided on the left and right sides of the cavity 14;

[0072] An inspection platform 24 connected with the support rod 22 and suspended on the track 1 through the guide wheel 21 and the support rod 22, the conductive brush 23 accessing the inspection platform 24, providing power supply and communication channel for the inspection platform 24.

[0073] The left guide part 11 and the right guide part 12 are connected together through the connecting part 13, as Figure 2 shown, the whole formed by the connection of the three is in an inverted U-shaped structure, or can be called a down C-shaped structure. The cavity 14 is located in the interior of the U-shaped structure. Of course, these structures can have corresponding deformations in form, but in general, the left guide part 11, the right guide part 12 and the connecting part 13 can basically be understood as a form structure having three closed surfaces and one open surface in a cross section. The opening is used for the inspection device 2 to extend into the cavity 14 to realize connection. In addition, the left guide part 11 and the right guide part 12 each have a chamber 15 communicating with the cavity 14 shown, which can be used to accommodate the slide strip 16. In this way, the slide strips 16 in the left and right chambers 15 can respectively make electrical contact with the inspection device 2 accessing the cavity 14 from the left and right sides.

[0074] The track 1 provided in the embodiment of this patent can accommodate the sliding contact bar 16 inside the guide rail through the setting of the cavity 14 and the chamber 15, and the inspection equipment 2 is connected to the cavity 14 and can be in electrical contact with the sliding contact bar 16. In other words, this patent integrates the sliding contact bar 16 into the interior of the track 1, so there is no need to set up the mobile track 1 and the sliding contact line track 1 separately, eliminating the installation, setting, and debugging operations for the synchronous movement of the two parallel tracks 1, thereby reducing the installation cost. Moreover, since the single-track structure is simpler, it can significantly reduce the occurrence rate of failures and save maintenance costs. More importantly, the single-track structure significantly reduces the space occupied, which can save more space while avoiding possible interference and collision.

[0075] In the embodiment of this patent, the track 1 itself may not include the sliding contact bar 16, which is installed by the user, or it may include two sliding contact bars 16, which are respectively arranged in the left and right chambers 15. The two sliding contact bars 16 are electrically contacted with the inspection equipment 2 connected to the cavity 14 from the left and right sides, respectively, to improve convenience.

[0076] In addition, since the sliding contact bar 16 is not exposed to the outside of the track 1, it can prevent the sliding contact bar 16 from being corroded by water vapor or accumulating excessive dust, which can simplify the structure and improve its connection reliability and working stability.

[0077] Further, such as Figure 2 and Figure 3 As shown, the left guide portion 11 and the right guide portion 12 can protrude toward each other to form a step 17, and the side of the step 17 facing the connecting portion 13 is used to support the guide wheel 21 of the inspection device 2. When the guide wheel 21 of the inspection device 2 is connected to the cavity 14, the step 17 can confine the guide wheel 21 inside the cavity 14, and the inspection device 2 can move along the length extension direction of the track 1 under the guidance of the guide wheel 21. Since the guide wheel 21 is embedded in the cavity 14, the enclosing structure formed by the left guide portion 11, the connecting portion 13 and the right guide portion 12 can also protect the guide wheel 21, thereby improving reliability. Obviously, the gap between the two steps 17 should be larger than the diameter of the support rod 22 to facilitate the support rod 22 to extend from the cavity 14 and connect to the inspection platform 24.

[0078] like Figure 2 As shown, at least one of the surfaces of the left guide portion 11 and the right guide portion 12 facing away from the connecting portion 13 is a driving surface 18 , which is used to provide friction for the driving wheel 25 of the inspection device 2 to drive the inspection device 2 to move.

[0079] Correspondingly, the inspection equipment 2 also includes a driving wheel 25, which is connected to the inspection platform 24 and abuts against the driving surface 18 of the track 1. The driving surface 18 is the side of the step 17 opposite to the guide wheel 21, that is, the surface of at least one part of the left guide part 11 and the right guide part 12 facing away from the connecting part 13.

[0080] When drive wheels 25 and drive surface 18 are provided, it's easy to understand that the guide wheels 21 and drive wheels 25 will clamp the step 17 from the top and bottom, respectively, to secure it. Specifically, the guide wheels 21 are positioned above the step 17 and supported by it, allowing the inspection device 2 to move back and forth along the length of the track 1. The drive wheels 25, on the other hand, are positioned on the inspection platform 24 and abut the drive surface 18 from below. When the drive wheels 25 rotate, the friction between them and the drive surface 18 drives the inspection device 2 along the track 1.

[0081] Under this structure, the driving force for driving the inspection equipment 2 to move is provided by the driving wheel 25, while the guide wheel 21 located inside the track 1 only serves as a driven wheel, used to guide the inspection equipment 2 to move, and does not provide driving force. In other words, the guide wheel 21 located inside the track 1 does not need to be connected to the drive mechanism for complex force transmission, so the connection relationship between the guide wheel 21 and the support rod 22 will be very simple. For example, the axle of the guide wheel 21 can be fixedly connected to the support rod 22, or even integrally formed. This not only reduces the space requirement for the connecting portion 13 of the guide wheel 21 and the support rod 22, but also enables the guide wheel 21 and the support rod 22 to have a stronger load-bearing capacity. Actual measurement results show that, under the premise of using conventional steel materials as the track 1, a cavity 14 with a width of about 10 cm can have a load-bearing capacity of more than 200 kg.

[0082] Further, see Figure 2 As shown, the driving wheel 25 is located below the track 1, so that the top of the track 1 is free, thereby providing the track 1 with the space required for hoisting. For example, a connecting mechanism can be provided above the track 1 and is evenly spaced along the length extension direction of the track 1. The connecting mechanism can be a sling, such as a lifting chain. One end of the sling is fixed to the roof, and the other end hangs down and is connected to the upper end face of the track 1. In actual application, the distribution interval of the connecting mechanism can be adjusted according to the load requirements of the track 1. It can be understood that the smaller the distribution interval of the connecting mechanism, the greater the number of connecting mechanisms, and the greater the load capacity of the track 1. The track 1 in the embodiment of this patent, through the setting of the driving surface 18, is arranged so that the driving wheel 25 that drives the inspection equipment 2 to move is arranged below the track 1, and the upper end face of the track 1 is used as the installation position for installing the track 1, so that the track 1 can provide a larger load.

[0083] Furthermore, the surfaces of the left and right guide portions 11 and 12 facing away from the connection portion 13 are located on the same plane and serve as drive surfaces 18. The term "same plane" as used herein refers to coplanarity, meaning that the two components are located at the same horizontal plane during hoisting. Obviously, if the two components are not located at the same horizontal plane, two or more drive wheels 25 can be provided, each with a corresponding drive wheel 25. Specifically, the drive wheels 25 are located below the track 1 and abut against the drive surfaces 18 of the left and right guide portions 11 and 12, respectively.

[0084] In the embodiment of the present invention, the track 1 is usually set as a straight line. At this time, the guide wheel 21 can be set to a state where it cannot rotate relative to the inspection platform 24, that is, the two ends of the support rod 22 are fixedly connected to the guide wheel 21 and the inspection platform 24 respectively.

[0085] In some applications, at least a portion of the track 1 may need to be curved to accommodate the movement of the inspection device 2. At a curve in the track 1, the outer and inner radii are unequal. When the drive wheel 25 simultaneously abuts the drive surfaces 18 of both the left and right guide sections 11, 12 while moving around the curve, the differential displacement between the outer and inner sides results in increased localized force, potentially causing the inspection device 2 to wobble slightly.

[0086] Therefore, to address the above issues, two drive wheels 25 can be provided, one corresponding to the drive surface 18 of the left guide portion 11 and the other corresponding to the right guide portion 12. When the inspection device 2 moves on a straight track 1, the two drive wheels 25 rotate at the same speed. However, when moving on a curved track 1, the rotational speeds of the two drive wheels 25 can be controlled based on the curvature of the track 1 to adapt to the path lengths on the inner and outer sides of the track 1, ensuring smooth movement of the inspection device 2 around curves in the track 1. Furthermore, by providing two drive wheels 25, the two drive wheels 25 can be controlled to move in opposite directions during movement, thereby achieving an emergency stop.

[0087] It is worth mentioning that one of them can be set as a driving wheel 25 and the other as a driven wheel, so that the driven wheel follows the movement of the driving wheel 25 to avoid the shaking problem caused by different strokes. Furthermore, the driving surface 18 on either side can be released from the abutment relationship with the driving wheel 25 at the turning point of the track 1. For example, the raising and lowering of the driving wheel 25 can be controlled so that it cannot act on the driving surface 18. At this time, the driving wheel 25 that has temporarily lost connection plays a role similar to that of the driven wheel. By setting the driving wheel 25 in this way, it still has the ability of bilateral driving on the straight track 1, so it can prevent the problem of unbalanced force caused by long-term unilateral force when one driving wheel 25 and one driven wheel are added, and the friction loss on one side of the track 1 is greater than that on the other side.

[0088] Furthermore, to increase the friction between the drive surface 18 and the drive wheel 25, the surface of the drive surface 18 may be roughened, specifically, with a surface roughness greater than Ra 3.2. In this case, the friction between the drive surface 18 and the drive wheel 25 can substantially meet the requirements for driving the inspection device 2 to move.

[0089] It should be noted that the surface roughness of aluminum profiles produced by die-casting or extrusion is generally between Ra3.2 and Ra6.3. Therefore, aluminum profiles produced by die-casting can meet basic requirements without further processing. Preferably, to further improve friction, the driving surface 18 can be further processed to achieve a surface roughness greater than Ra6.3.

[0090] The surface of the metal drive surface 18 will wear due to long-term friction with the drive wheel 25, resulting in a decrease in surface roughness, which gradually reduces the friction between the drive surface 18 and the drive wheel 25. To solve this problem, a rubber layer can also be attached to the smooth drive surface 18, so that the rubber layer is in direct contact with the drive wheel 25 and provides the friction required to drive the inspection device 2. Rubber has strong wear resistance, and after the rubber layer is worn, the rubber layer can be replaced to ensure that the friction meets the use requirements. Compared with aluminum profiles, the rubber layer has a certain elasticity, can provide greater friction, and is less likely to generate noise, so it has many advantages.

[0091] Based on the above technical solution, in the embodiment of the present invention, a patrol inspection system 3 is also proposed, such as Figure 1 As shown, it includes the above-mentioned track 1 and the inspection device 2, which is installed on the track 1, and an image acquisition device 31, which is detachably installed on the inspection platform 24.

[0092] It is understood that the inspection device 2 in the embodiment of the present invention is installed on the track 1 and can move back and forth along the length of the track 1. The inspection platform 24 can be used as an installation location for other devices. In actual applications, corresponding devices can be installed on the inspection device 2 according to the use environment and actual needs of the inspection system 3 to achieve the intended functions.

[0093] For example, the inspection system 3, inspection equipment 2 and track 1 mentioned in the embodiment of this patent, and the image acquisition device 31 provided therein can not only be used for data collection of the electric control box 4 mentioned above, but also be applicable to some other application scenarios. For example, in the process of agricultural research, multiple experimental chambers may be set up to compare the growth of plants under different conditions. At this time, the track 1 provided by this patent can also be arranged around the experimental chamber, and the inspection equipment 2 provided by this patent can be used to obtain image data in the experimental chamber from multiple angles and with high precision.

[0094] In addition to the image acquisition device 31 , many other possible devices may be mounted on the inspection device 2 , such as a mechanical arm, a sound acquisition device, a rod-shaped operating device, a hook, and the like.

[0095] Implementation Method 2

[0096] This embodiment is a further improvement based on the first embodiment. Figure 2 and Figure 3 As shown, the improvements are:

[0097] Hanging grooves 191 are respectively provided on the opposite surfaces of the left guide part 11 and the right guide part 12. The hanging grooves 191 are side by side with the chamber 15 of the guide part and are separated by a partition wall. The hanging grooves 191 are used to hang the associated devices of the inspection equipment 2.

[0098] The mounting slot 191 provides a mounting location for associated devices of the inspection device 2. Such associated devices are typically fixed to the track 1 and do not move with the inspection device 2. In actual use, the associated devices may be environmental monitoring devices such as temperature sensors, humidity sensors, or other devices that meet actual needs.

[0099] In addition, a hoisting groove 192 is provided on the left guide portion 11 and the right guide portion 12 respectively. The hoisting groove 192 is located on the side opposite to the driving surface 18 , and is used for hoisting the rail 1 .

[0100] It is worth noting that the track 1 is typically made of aluminum profiles produced by die-casting or extrusion. The mounting slots 191 and 192 are directly provided on the track 1 and can be directly formed during the production process of the track 1. Furthermore, the provision of the mounting slots 191 and 192 reduces the amount of aluminum used, thereby reducing production costs and the weight of the track 1 while ensuring that the structural strength of the track 1 meets the requirements.

[0101] In addition, blocking eaves 193 may be provided on both sides of the opening of the cavity 15 along the width direction, respectively. The blocking eaves 193 are used to prevent the sliding contact strip 16 from separating from the cavity 15 .

[0102] Implementation Method 3

[0103] This embodiment is a further improvement based on the first or second embodiment, and its main improvement is that, see Figure 3 and Figure 4 As shown, the inspection equipment 2 includes:

[0104] The fixed shaft 252 type motor includes a motor wheel 251 and a fixed shaft 252 extending from the motor wheel 251; the motor wheel 251 constitutes at least a part of the driving wheel 25;

[0105] The elastic device is provided on the inspection platform 24 , and the fixed shaft 252 is mounted on the elastic device so as to be held against the driving surface 18 of the track 1 under the elastic force of the elastic device.

[0106] It is worth noting that commonly used motors usually include a stator and a rotor as a rotating output shaft. During actual use, the stator is fixed in the installation position, and the rotor rotates relative to the stator and transmits the rotational driving force outward. However, when a motor of this structure is applied to the structure of the present invention, a transmission structure needs to be set up to connect the output shaft and the drive wheel 25, so it takes up a large amount of space. Since the diameter of the output shaft is very small, the transmission structure usually also includes a series of components such as a reducer and a pulley to transmit torque, increase the torque output, and control the speed of the drive wheel 25. The reducer brings power loss in the process of transmitting torque, and also increases the extra space occupied, reducing the reliability of the system.

[0107] The difference from the commonly used motors is that the fixed shaft 252 type motor used in this patent, as the fixed shaft 252 of the stator is fixed on the inspection platform 24, and the motor housing as the rotor, that is, the motor wheel 251, rotates with the fixed shaft 252 as the rotation axis. On this basis, the motor wheel 251 itself constitutes the drive wheel 25. The motor wheel 251 has a considerable diameter, so the rotation speed will not be too fast and the torque is sufficient, so there is no need to set up an additional transmission structure. The motor wheel 251 can be placed in the center under the track 1 and does not need to be offset, so it is beneficial to maintain the center of gravity of the inspection equipment 2. In summary, in the embodiment of this patent, the fixed shaft 252 type motor is used, which has the advantages of simple structure, small space required, good stability and long service life.

[0108] For this patent, the elastic device can be any structure that can push the fixed shaft 252 so that the motor wheel 251 is held against the track 1. For example, the elastic device can be provided by a plurality of mechanisms such as a spring 265 and a spring 264.

[0109] Specifically, if Figure 3 and Figure 4As shown, the elastic means may include:

[0110] A clamping plate 261, on which the fixed shaft 252 is mounted;

[0111] The spring piece 265 is connected to one side of the clamping plate 261 and fixed on the inspection platform 24;

[0112] A fixed column 262 is fixed on the inspection platform 24. A blocking piece 263 is provided on the fixed column 262. The clamping plate 261 is sleeved on the fixed column 262.

[0113] The spring 264 is mounted on the fixing column 262 . Both sides of the spring 264 respectively abut the blocking piece 263 and the clamping plate 261 to push the clamping plate 261 toward the guide wheel 21 , thereby abutting against the driving surface 18 of the track 1 .

[0114] The above elastic device is only an illustration of this patent. It is understandable that a large number of elastic devices in the prior art can achieve the technical purpose of this application. The spring 264 and the spring piece 265 provided can push the clamping plate 261 to move toward the direction of the track 1. This allows the fixed shaft 252 installed on the clamping plate 261 to move toward the direction of the track 1, and allows the driving wheel 25 to always be held against the driving surface 18 of the track 1. In this elastic device, the spring 264 provides the main elastic force, while the spring piece 265 plays an auxiliary role, making the movement of the clamping plate 261 more stable and even having a good shock-absorbing effect.

[0115] In addition, the driving wheel 25 may further include:

[0116] The rubber ring is removably mounted on the motor wheel 251. The rubber ring is elastic and wear-resistant, increasing the contact friction between the drive surface 18 and the drive wheel 25. Furthermore, if the rubber ring wears out and the friction is insufficient, it can be replaced to restore the friction. Furthermore, the rubber ring acts as an elastic buffer, preventing hard contact between the motor wheel 251 and the drive surface 18, effectively reducing noise.

[0117] Implementation Method 4

[0118] The inventors of this patent have discovered that, in actual use, due to the long-term movement of the inspection device 2 on the track 1, the conductive brush 23 presses on the sliding contact bar 16, which may cause the sliding contact bar 16 to loosen or deform. This embodiment provides a further improvement based on any of the first to third embodiments. The main improvement is that an elastic member is further provided in the chamber 15. The elastic member abuts against the sliding contact bar 16 and pushes the sliding contact bar 16 toward the direction of the cavity 14 and abuts against the blocking eaves 193.

[0119] When leaving the factory, the elastic part and the sliding contact bar 16 can be pre-installed in the track 1. The elastic part can push the sliding contact bar 16 to move toward the cavity 14, that is, the direction of the conductive brush 23, so that when the sliding contact bar 16 becomes loose or deformed, it can still always be supported on the blocking eaves 193, thereby maintaining its electrical contact with the conductive brush 23, thereby extending the service life of the track 1.

[0120] This patent does not provide detailed restrictions on the specific structure of the elastic member; for example, a flexible sponge structure can be used. However, this embodiment still provides an improved elastic member arrangement. In this arrangement, as shown in Figure 6 , the elastic member can include a support block 151 and a compression spring 152 connected to the support block 151. The other end of the compression spring 152 is connected to the bottom wall of the chamber 15. The compression and expansion of the compression spring 152 can push the support block 151 to move, thereby pressing against the sliding contact bar 16.

[0121] When users need to adjust the length of the track 1 according to actual site requirements and need to assemble the sliding contact bar 16 themselves, the presence of the elastic member may hinder the installation of the sliding contact bar 16. In view of this, the elastic member can be fixed in a contracted state by wax or glue sealing, and the wax or glue seal can be released after heating to restore it to the expanded state.

[0122] That is, at the factory, the elastic member is compressed to its limit by wax or glue sealing. The user only needs to insert the sliding contact bar 16 into the cavity 15 and then heat the track 1 to remove the wax or glue seal, so that the elastic member can abut against the sliding contact bar 16 to achieve the above technical purpose. Specifically, the wax or glue sealing method can be achieved by bonding the abutment block 151 to the bottom wall of the cavity 14 with wax or hot melt adhesive.

[0123] It will be apparent to those skilled in the art that this patent is not limited to the details of the exemplary embodiments described above, and that this patent can be implemented in other specific forms without departing from the spirit or essential characteristics of this patent. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of this patent is defined by the appended claims rather than the foregoing description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims be encompassed within this patent. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
