With the development of technology, the existing container gantry crane is generally provided with a current collecting mechanism and a wireless communication mechanism, and is matched with a trolley wire in a guide rail arranged in a goods yard to realize power supply of the crane and communication with a central control room. When the crane moves to hoist the container, the load is heavier, the working environment of a goods yard is complex, the crane is easy to shake and even move, and the current collecting mechanism on the crane is in poor contact with the power supply trolley wire, so that the power supply of the crane is unstable, and the normal operation of the crane is influenced.

For solving the problem that crane current collecting mechanism gets electrical stability not high, chinese patent application publication No. CN206432541U discloses a novel low altitude wiping line and gets electrical apparatus, and it drives the frame and sets up the current collector on the driving, is provided with the current collector equipment frame on the current collector, drives the driving and is provided with on the frame and drives the frame mounting panel, drives and is provided with the elasticity on the frame mounting panel and gets the electric arch, and the current collector equipment frame is through elasticity and get electric arch and drive frame mounting panel elastic connection, spacing subassembly including spacing track and rather than the spacing wheel of adaptation. The current collector is arranged on the current collector assembly frame, the current collector assembly frame is arranged on the driving frame through the springs, and when equipment such as a stacker, a stacker-reclaimer and a reclaimer shakes, the springs arranged between the current collector assembly frame and the driving frame deform and can absorb shaking energy, so that the stability of the current collector can be greatly ensured. The limiting component can further improve the stability of the current collector assembly frame, and further improves the power taking stability of the device.

Although the above patent application can reduce the influence on the power taking stability caused by shaking of the equipment to a certain extent, the current collector and the sliding contact wire are of a simple plug-in type connection structure, the connection is unstable, and the problem that the power supply stability of the equipment is influenced due to poor contact between the current collector and the sliding contact wire still exists.

The special structural design of the current collection/communication mechanism in the communication power supply system is adopted, so that the current collection/communication mechanism is assembled and disassembled with the guide rail more conveniently, meanwhile, the contact stability between the sliding contact wire and the electric brush is ensured, the occurrence of poor contact phenomenon is reduced, the current collection/communication mechanism is smoother when moving along with the crane, and the power supply stability of the crane is improved.

Fig. 1 to 3 show an embodiment of a container gantry crane communication power supply system, wherein fig. 1 is a perspective view of the embodiment, and fig. 2 and 3 are an exploded view of the structure and a sectional view of a part of the structure, respectively.

As shown in fig. 1 to 3, the container gantry crane communication power supply system of this embodiment includes a bracket 1, a guide rail 2, a power supply/communication trolley line 3, and a power collection/communication mechanism 4.

The supports 1 are arranged on the ground, and the number of the supports is a plurality of supports, and the specific number of the supports is determined according to the requirements of places, crane operation and the like. A guide rail 2 is provided on the bracket 1, in particular at the upper part of the bracket 1 near its top. The opening of the guide rail 2 faces downwards, and a plurality of power supply/communication trolley wires 3 are arranged inside the guide rail 2. The power supply trolley wire for transmitting electric energy is a metal guide rail wrapped with an insulator, the communication trolley wire for transmitting information is in a semi-closed catheter shape, and a groove is formed in the communication trolley wire. The ground communication device and the ground power supply device are arranged on the ground on one side of the bracket 1, and the power supply trolley wire is connected with the ground power supply device through a circuit. The ground communication device is connected with the central control room through optical fibers, receives optical fiber signals sent by the central control room, converts the optical fiber signals into radio signals and then transmits the radio signals to the communication trolley wire in the guide rail 2; the ground communication device also receives wireless signals from the communication trolley wire, converts the wireless signals into optical fiber signals and transmits the optical fiber signals to the central control room.

The collecting/communicating means 4 are connected to the rail 2 and the crane (not shown in the figures), respectively, which will slide on the rail 2 following the movement of the crane as it moves along the rail 2, for obtaining the electrical energy required by the crane from the rail 2, and also for communication between the crane and the communication trolley in the rail 2. The current collecting/communicating mechanism 4 includes a moving portion 41, a mounting portion 42, an adjusting portion 43, a follower portion 44, a transmitting portion 45, a holding portion 46, and a brush and communicating antenna 47. The respective partial structures of the current collecting/communicating mechanism 4 are described in detail below.

The moving part 41 is slidably mounted at the bottom of the guide rail 2 and connected to the crane, and is capable of driving the whole collecting/communicating mechanism 4 to slide on the guide rail 2 following the movement of the crane.

The mounting portion 42 is connected to the moving portion 41, the follower portion 44 is slidably mounted on the moving portion 41, and the mounting portion 42 and the follower portion 44 are further connected through a transmission portion 45. The adjustment portion 43 is used to adjust the mounting portion 42 so that the mounting portion 42 can move relative to the moving portion 41. Further, the transmission portion 45 is provided such that the mounting portion 41 and the follower portion 44 move in opposite directions on the moving portion 41. Specifically, if the mounting portion 42 moves upward on the moving portion 41, the follower portion 44 slides downward on the moving portion 41; when the mounting portion 42 moves downward on the moving portion 41, the follower portion 44 slides upward on the moving portion 41.

The top of the mounting part 42 is provided with a brush and a communication antenna 47, the brush is used for taking electricity from the power supply trolley wire after contacting with the power supply trolley wire in the guide rail 2, and transmitting the obtained electric energy to an electric energy receiving device of the crane, and the communication antenna is used for communicating with the communication trolley wire in the guide rail 2, so that information transmission between the crane and a central control room is realized.

The holding portion 46 is rotatably connected to the moving portion 41, and the holding portion 46 is rotatable relative to the moving portion 41 about a rotation axis. The clamping portion 46 is further slidably connected to the following portion 44, and the following portion 44 is further connected to the mounting portion 42, where the connection relationship between the three is as follows: when the mounting portion 42 moves on the moving portion 41 and approaches the power supply/communication trolley wire 3, the follower portion 44 slides in the opposite direction to the mounting portion 42, and the holding portion 46 will hold the guide rail 2 by the follower portion 44; while the mounting portion 42 moves on the moving portion 41 and moves away from the power supply/communication trolley wire 3, the follower portion 44 slides in the opposite direction to the mounting portion 42, and the holding portion 46 releases the guide rail 2 by the follower portion 44.

With the container gantry crane communication power supply system having the above-described structure, in the process of adjusting the upward movement of the mounting portion 42 on the moving portion 41 by the adjusting portion 43 to bring the power supply/communication trolley wire 3 in the guide rail 2 closer to contact, the follower portion 44 is driven by the transmission portion 45 to slide in the direction opposite to the moving direction of the mounting portion (i.e., in the downward direction away from the guide rail 3), and the sliding of the follower portion 44 drives the clamping portion 46 to rotate on the moving portion 41 and clamp the guide rail 2, so that the installation of the power collection/communication mechanism 4 and the guide rail 2 is realized. In the process of adjusting the mounting part 42 to move downwards on the moving part 41 and away from the power supply/communication trolley wire 3 in the guide rail 2 by using the adjusting part 43, the driving part 45 drives the follower part 44 to slide towards the upward direction opposite to the moving direction of the mounting part 42, and the sliding of the follower part 44 drives the clamping part 46 to rotate on the moving part 41 and release the guide rail 2, so that the power supply/communication mechanism 4 is detached from the guide rail 2. By utilizing the current collecting/communicating mechanism provided by the invention, only the adjusting part 43 is required to be operated, so that the assembly and disassembly of the current collecting/communicating mechanism 4 and the guide rail 2 of the crane are conveniently realized, and when the current collecting/communicating mechanism is assembled to the guide rail, the tight and stable connection between the current collecting/communicating mechanism and the guide rail can be realized by utilizing the clamping effect of the clamping part 46, so that the stable contact between the electric brush on the mounting part 42 and the power supply trolley wire in the guide rail 2 is ensured, and the problem of unstable power supply caused by poor contact between the electric brush and the power supply trolley wire is avoided.

In other embodiments, the communication power supply system further comprises a buffer mechanism 48 connected to the crane and the collecting/communicating mechanism 4, so as to reduce the problem that the power supply cannot be stably supplied due to the fact that the collecting/communicating mechanism 4 is pulled when the crane vibrates and deflects.

Referring to fig. 1 to 5, the buffer mechanism 48 includes a first connection portion 481 fixedly connected to the crane, a second connection portion 482 slidably connected to the first connection portion 481, an elastic member 483 and a third connection portion 484 respectively connected to the first connection portion 481 and the second connection portion 482, and the third connection portion 484 is rotatably connected to the second connection portion 482 through a second hinge shaft 4821 and is rotatably connected to the moving portion 41 through a first hinge shaft 417. The connection of the crane to the power collecting/communicating means 4 is achieved by the first connection 481, the second connection 482 and the third connection 484 of the buffer means 48, on the one hand, and the crane also pulls the moving part 41 to slide on the guide rail 2 by the buffer means 48, in particular the third connection 484 thereof.

After the crane is connected to the collecting/communicating means 4 via the buffer means 48, if a change in distance and/or height occurs between the crane and the collecting/communicating means 4, the first connection portion 481 fixedly connected to the crane changes in accordance with the crane. If the first connection portion 481 moves horizontally and moves closer to the current collecting/communicating means 4, since the second connection portion 482 and the first connection portion 481 are in sliding connection, and the elastic member 483 is further connected between the second connection portion 482 and the first connection portion 481, the connection between the current collecting/communicating means 4 and the guide rail 2 can be kept stable by pressing the elastic member 483 (when the elastic member is in a free state) or reducing the tension of the elastic member 483 (when the elastic member is in a stretched state), so that the second connection portion 482 and the first connection portion 481 slide relatively to change the horizontal distance between them and the first connection portion 481, but the connection position between the second connection portion 482 and the third connection portion 484 is kept unchanged. If the first connection portion 481 moves in the horizontal direction and moves away from the current collecting/communicating mechanism 4, the second connection portion 482 and the first connection portion 481 can slide relative to each other to change the horizontal distance between the second connection portion 482 and the first connection portion 481 by stretching the elastic element 483 (when the elastic element is in a free state) or reducing the compression of the elastic element 483 (when the elastic element is in a compressed state), but the connection position between the second connection portion 482 and the third connection portion 484 is kept unchanged, the position of the current collecting/communicating mechanism 4 is not affected, and the connection between the current collecting/communicating mechanism 4 and the guide rail 2 is kept stable.

If the first connection portion 481 changes its height in the vertical direction along with the crane, the height between the second connection portion 482 and the third connection portion 484 also changes, and the third connection portion 484 is rotatably connected to the second connection portion 482 and also rotatably connected to the moving portion 41, the third connection portion 482 adjusts its position by rotation without affecting the position of the current collecting/communicating mechanism 4, so that the connection between the current collecting/communicating mechanism 4 and the guide rail 2 is kept stable.

By utilizing the buffer mechanism, the pulling of the current collecting/communicating mechanism 4 during the operation of the crane is reduced, so that the current collecting/communicating mechanism 4 can actively keep the position of the guide rail 2 stable, and the stability of power supply is further ensured.

Since the crane mainly pulls the moving part 41 to slide on the guide rail 2 through the third connecting part 484, the third connecting part 484 needs to be made of a rigid material. While the rigid third connection 484 can function as a buffer to some extent, it is difficult to achieve accurate buffering, so that there is a risk of the collector/communicator 4 being pulled by the crane. To solve this problem, in other embodiments, the cushioning mechanism further includes a sprocket and chain structure. Specifically, a first sprocket 485 rotatably connected to the first hinge shaft 417 is provided on the first hinge shaft 417, a second sprocket 486 fixedly connected to the second hinge shaft 4821 is provided on the second hinge shaft 4821, and chains 487 are provided on the first sprocket 485 and the second sprocket 486. Through setting up the flexible buffer structure that sprocket and chain constitute, can comparatively accurately respond to abnormal movements such as displacement and vibrations of hoist to carry out buffer adjustment accurately, and then further reduce the risk that current collection/communication mechanism 4 was pulled, improved the stable connection of current collection/communication mechanism 4 and guide rail 2.

The structure of the communication power supply system of this embodiment is specifically described below with further reference to fig. 1 to 5.

The moving portion 41 includes an upper plate 411 and a lower plate 412, which form an operation space therebetween. The middle positions of the left side edge and the right side edge of the upper plate 411 are respectively provided with a turnover part 413 extending upwards, and a front avoidance part 414 and a rear avoidance part 414 are formed between each turnover part 413 and the side edge of the upper plate 411.

A screw hole 415 penetrating therethrough is formed on the bottom surface of the upper plate 411, and a downward extending extension 416 is provided at the bottom of the lower plate 412. Specifically, the extension portion 416 includes two extension plates disposed at a front-rear interval, and a first hinge shaft 417 is disposed between the two extension plates.

Grooves are formed in the middle of the inner sides of the front side frame and the rear side frame of the closed frame 441 respectively, a first sliding groove 444 is arranged on each groove respectively, and the first sliding groove 444 extends left and right in the groove of the side frame where the first sliding groove 444 is located to form a strip-shaped groove-shaped structure. The follower inclined surfaces 443 are formed on the outer sides of the left and right side frames of the closed frame 441, respectively, and the follower inclined surfaces 443 are inward-folded inclined surfaces from top to bottom. The follower portion 44 is integrally located on the moving portion 41, specifically, in an area surrounded by the bottom plate of the upper plate 411 and the two turnups 413.

The mounting portion 42 has a block structure adapted to the shape of the cavity 442 of the follower portion 44, and the size of the outer rim thereof is slightly smaller than the largest dimension of the cavity 442, so that the mounting portion 42 can be accommodated in the cavity 442 and can freely enter and exit the cavity 442. A brush and a communication antenna 47 are provided on the top surface of the mounting portion 42, and a positioning hole (not shown) is provided on the bottom surface of the mounting portion 42. The positioning hole is a blind hole, and corresponds in position to the screw hole 415 in the moving part 41 in the up-down direction. Second sliding grooves 421 are respectively arranged in the middle of the outer side surfaces of the front side frame and the rear side frame of the mounting part 42, and the positions of the second sliding grooves 421 correspond to the first sliding grooves 444 in the follow-up part 44.

The transmission part 45 includes two sets of cross lifting mechanisms, namely a first cross lifting mechanism 451 and a second cross lifting mechanism 452, which are symmetrically disposed inside the closed frame 441 of the follower part 44. The structure and connection relationship of the first cross lifting mechanism 451 will be described by way of example.

The first cross lifting mechanism 451 includes a support plate 4511 located in the cavity 442 of the follower portion 44, adjacent to and fixed to the front side frame of the closed-type frame 441, specifically, fixed at the front side frame corresponding to the middle position of the first chute 444. A transmission part hinge shaft (not shown) extending toward the inside of the hermetic frame 441 is provided at an upper portion of the supporting plate 4511, and a first cross lifter 4513 and a second cross lifter 4514 are hinged to the transmission part hinge shaft, each of which is provided at both ends thereof with a stopper post 4515, respectively. Wherein, the limit post 4515 at one end of the first cross lifting lever 4513 is disposed in the first chute 444 on the follower portion 44, and the limit post 4515 at the other end thereof is disposed in the second chute 421 on the mounting portion 42; similarly, the limit post 4515 at one end of the second cross lifter 4514 is disposed in the first slide groove 444 on the follower portion 44, and the limit post 4515 at the other end thereof is disposed in the second slide groove 421 on the mount portion 42. By the cooperation of the limit post 4515 and the first chute 444, the sliding connection of the follower 44 with the first cross lifting mechanism 451 and the second cross lifting mechanism 452 is realized; the sliding connection of the mounting portion 42 with the first and second cross lifting mechanisms 451, 452 is also achieved through the cooperation of the limit post 4515 and the second slide slot 444. Further, by the transmission portion 45 constituted by the two sets of intersecting elevating mechanisms, it is realized that the follower portion 44 and the mounting portion 42 can slide in opposite directions on the moving portion 41.

The adjustment portion 43 is an adjustment bolt, the stud of which passes through the threaded hole 415 on the moving portion 41, and the top of which is placed in the positioning hole of the mounting portion 42. The connection and positioning between the mounting portion 42 and the moving portion 41 are achieved by the fitting of the adjustment portion 43, the screw hole 415, and the positioning hole. Since the follower portion 44 and the mounting portion 42 are connected and limited by the transmission portion 45, connection and limitation among the moving portion 41, the mounting portion 42 and the follower portion 44 are further realized, and stable movement of the mounting portion 42 and the follower portion 44 relative to the moving portion 41 is ensured.

The clamping portion 46 includes two half-surrounding frames, i.e., a first half-surrounding frame 461 and a second half-surrounding frame 462, which are symmetrically disposed, and are respectively located on the left and right sides of the follower portion 44. The structure and connection relationship of the first half enclosure 461 will be described below by taking the first half enclosure 461 as an example.

The first half surrounding frame 461 includes a first half surrounding frame 4611, a second half surrounding frame 4612, and a connecting frame 4613, and the first half surrounding frame 4611 and the second half surrounding frame 4612 are disposed at intervals in the longitudinal direction of the rail 2, and are connected by the connecting frame 4613 in the lateral direction.

The first half surrounding frame 4611 includes a first lateral extension 46111, a first longitudinal extension 46113, and a first diagonal adduction 46114, which are connected in sequence. The first lateral extension 46111 extends from an outer side (left side in this embodiment) of the bottom of the rail 2 to the follower 44 in the width direction of the rail 2, and the free end of the first lateral extension 46111 at the bottom of the rail 2 is slidably connected to the follower 44. Specifically, the free end of the first lateral extension 46111 has a clamping portion inclined surface 46112 that is folded inwardly from bottom to top, and the follower portion inclined surface 443 of the closed frame 441 of the follower portion 44 that faces the first lateral extension 46111 slides against the clamping portion inclined surface 46112. The first longitudinally extending portion 46113 extends from the bottom of the rail 2 to the top of the rail 2 in the height direction of the rail 2, and the first obliquely-folded portion 46114 is folded inwardly from the outside of the rail 2 to the top of the rail 2 in a direction surrounding the rail 2. The first half surrounding frame 4611 further includes a first roller 46115 disposed on the first angled inner portion 46114. When the clamping portion 46 clamps the rail 2, the first roller 46115 is closely attached to the rail 2, and thus, when the crane moves along the rail 2, the current collecting/communicating mechanism 4 can slide on the rail 2 by the first roller 46115, thereby improving the smoothness of the sliding.

The second half surrounding bezel 4612 includes a second lateral extension 46121, a second longitudinal extension 46123, and a second diagonal adduction 46124, which are connected in sequence. The second lateral extension 46121 extends from an outer side (left side in this embodiment) of the bottom of the guide rail 2 to the follower 44 in the width direction of the guide rail 2, and the free end of the second lateral extension 46121 at the bottom of the guide rail 2 is slidably connected to the follower 44. Specifically, the free end of the second lateral extension 46121 has a bottom-up inwardly received clamping portion slope 46122, and the follower portion slope 443 of the enclosed frame 441 of the follower portion 44, facing the second lateral extension 46121, slides against the clamping portion slope 46122. The second longitudinally extending portion 46123 extends from the bottom of the rail 2 to the top of the rail 2 in the height direction of the rail 2, and the second obliquely-folded portion 46124 is folded inwardly from the outside of the rail 2 to the top of the rail 2 in a direction surrounding the rail 2. The second half surrounding frame 4612 further includes a second roller 46125 disposed on the second angled inner portion 46124. When the clamping portion 46 clamps the rail 2, the second roller 46125 is also closely attached to the rail 2, so that the current collecting/communicating mechanism 4 can slide on the rail 2 by the second roller 46125 when the crane moves along the rail 2, thereby improving the smoothness of the sliding.

In addition, the first lateral extension portion 46111 is further formed with a shaft hole 46116, and the second lateral extension portion 46121 is further formed with a shaft hole 46126, both of which are rotatably connected to the first rotation shaft 418 of the moving portion 41, so that the first half surrounding frame 461 is rotatably connected to the moving portion 41. Correspondingly, the second half surrounding frame 462 is also provided with a shaft hole for rotationally connecting with the second rotating shaft 419 on the moving part 41, so as to realize the rotational connection of the second half surrounding frame 462 and the moving part 41.

The first connection portion 481 of the buffer mechanism 48 is a frame-like structure having a cavity, and is fixedly connected to the crane. A plurality of cables (not shown) are provided on the surface of the first connection portion 481, one end of each cable is connected to an electric component and a communication component in the crane, and the other end is connected to the current collecting/communication mechanism 4. The second connecting portion 482 is also a frame structure, and part of the second connecting portion is located in the cavity of the first connecting portion 481 and can be slidably connected with the first connecting portion 481 through a sliding rail and a sliding groove structure (not shown). Also provided inside the cavity of the first connection portion 481 is an elastic member 483, and specifically, the elastic member 483 may be a spring. One end of the spring is connected to the bottom wall of the cavity (right side wall of the cavity in the drawing) of the first connecting portion 481, and the other end is connected to the side wall of the second connecting portion 482 close to the bottom wall of the cavity. A second hinge shaft 4821 is provided at an end of the second connection portion 482 remote from the elastic member 483. The third connecting portion 484 of the buffer mechanism 48 is a racetrack frame structure, and an inner wall of an arc portion at one end thereof is rotatably connected to a portion of the first hinge shaft 417, and an inner wall of an arc portion at the other end thereof is rotatably connected to a portion of the second hinge shaft 4821. The first hinge shaft 417 is further sleeved with a first sprocket 485, the first sprocket 485 is rotatably connected to the first hinge shaft 417, and the position of the first sprocket 485 on the first hinge shaft 417 is different from the position of the third connecting portion 484 rotatably connected to the first hinge shaft 417. A second sprocket 486 is further sleeved on the second hinge shaft 4821, the second sprocket 486 is fixedly connected with the second hinge shaft 4821, and the position of the second sprocket 486 on the second hinge shaft 4821 is different from the position of the third connecting portion 484 rotatably connected with the second hinge shaft 4821. In this embodiment, the frame structure of the third connecting portion 484 extends in the width direction toward the first sprocket 485 and the second sprocket 486 for the chain 487 until the outer surfaces of the two sprockets and the chain are enclosed (but not in contact with the sprockets and the chain), thereby providing protection and aesthetic effects to the sprocket and chain structure.

The assembly process of the communication power supply system with the specific structure is as follows:

first, the guide rail 2 is mounted to a position on one side of a crane movement path by using the bracket 1.

Then, the current collecting/communicating mechanism 4 is mounted to the guide rail 2. Specifically, the top of the moving part 41 is attached to the bottom of the guide rail 2; then the adjusting bolt as the adjusting part 43 is turned to move upwards, the stud thereof pushes the mounting part 42 upwards until the brushes at the top of the mounting part 42 and the brushes in the communication antenna 47 are contacted with the power supply trolley line of the power supply/communication trolley line 3 in the guide rail 2, and the communication antennas in the brushes and the communication antenna 47 enter into the inner groove of the communication trolley line of the power supply communication trolley line 3. After assembly, the communication antenna is not contacted with the inner wall of the communication sliding contact line, so that friction is reduced. In the process of upward movement of the mounting portion 42, the limit posts at the upper ends of all lifting rods of the two crossed lifting mechanisms of the transmission portion 45 slide in opposite directions in the second sliding groove 421 of the mounting portion 42, so as to drive the crossed lifting rods to rotate on the hinge shaft of the transmission portion, further drive the limit posts at the lower ends of the lifting rods to slide in opposite directions in the first sliding groove 444 of the follow-up portion 44, and finally enable the follow-up portion 44 to move downward. The follower 44 moves downward, so that the follower inclined surface 443 and the clamping part inclined surfaces 46112, 46122 slide against each other, and under the pressing action of the follower inclined surface 443, the two half-enclosed frames of the clamping part 46 rotate along the first rotating shaft 418 and the second rotating shaft 419, so that the top ends of the two inclined adduction portions of each half-enclosed frame move toward the direction of clamping the guide rail 2, and each roller abuts against the guide rail 2. At this time, the current collecting/communicating mechanism 4 assumes the first state as shown in fig. 4.

Finally, the current collecting/communicating mechanism 4 is fixed with the crane through the buffer mechanism 48, and the arrangement and the assembly of the communication power supply system are completed.

If the current collecting/communicating mechanism 4 is to be detached from the guide rail 2, only the adjusting bolt is required to be turned to move downwards, the mounting part 42 moves downwards along with the adjusting bolt, the mounting part 42 and the transmission part 45 drive the follower part 44 to move upwards, the pressing force of the follower part 44 to the clamping part 46 is relieved, the semi-enclosed frame bodies of the clamping part 46 rotate along the rotating shaft, and the top ends of the two inclined inward-folding parts of each semi-enclosed frame body move towards the direction far away from the guide rail 2 to loosen the guide rail 2. At this time, the current collecting/communicating mechanism 4 assumes the second state as shown in fig. 5. Finally, the moving part 41, the mounting part 42, the adjusting part 43, the follower part 44, the transmission part 45 and the clamping part 46 are removed from the guide rail 2, and the current collecting/communicating mechanism 4 is removed from the guide rail 2.

The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
