Description

Technical Field

[0001] The present invention relates to the field of rail transportation equipment, and particularly to a raceway beam support assembly and a long rail transport vehicle. Background Art

[0002] In the construction of railways, long rail car sets are responsible for the tasks of loading, transporting, unloading long rails and recycling old rails. The long rail transport car set consists of various vehicle types, among which the rail transport vehicle with a raceway beam is the most numerous vehicle type in the long rail transport car set. The raceway beam is the main structure for carrying rails on the rail transport vehicle. Each rail transport vehicle is provided with a plurality of raceway beam supports. Every two of these raceway beam supports form a group and are arranged at intervals along the length direction of the vehicle body. The two raceway beam supports in each group of raceway beam supports are respectively installed on the left and right sides of the vehicle body. Among them, one of the raceway beam supports in each group of raceway beam supports includes a support column fixed on the vehicle body, and the other raceway beam support mainly consists of a column and a plurality of raceway beams arranged in sequence from top to bottom. Each raceway beam is rotatably connected to the column.

[0003] When the raceway beam rotates to be perpendicular to the length direction of the vehicle body and bears on the column and the support column, at this time, when the raceway beam is in the working state, the rail can be loaded on the raceway beam to realize the support of the long rail; when the raceway beam rotates to be parallel to the length direction of the vehicle body, the raceway beam is in the non - working state.

[0004] However, the rotation of the existing raceway beam relative to the column is realized through a hydraulic cylinder. That is to say, a separate hydraulic cylinder is provided for each layer of the raceway beam to drive the rotation of that layer of the raceway beam relative to the column, so as to make the raceway beam rotate to the working state and the non - working state. Specifically, the raceway beam is installed on a rotating sleeve sleeved outside the column, and the rotating sleeve is rotatably connected to the hydraulic cylinder through a crank. Thus, through the reciprocating movement of the hydraulic cylinder piston, the rotation of the rotating sleeve relative to the column can be realized, and then the raceway beam installed on the rotating sleeve can be driven to switch between the working state and the non - working state. However, this increases the manufacturing and operation and maintenance costs of the long rail transport vehicle, and the working efficiency of switching the working state and the non - working state of the raceway beam is low. Summary of the Invention

[0005] The present invention provides a raceway beam support assembly and a long rail transport vehicle to solve the problems in the prior art that the manufacturing, operation and maintenance costs of the long rail transport vehicle are high due to the hydraulic cylinder driving the raceway beam, and the working efficiency of switching the working state and the non - working state of the raceway beam is low.

[0007] In a possible implementation manner, the electric bolt includes an electric push rod and a bolt. The electric push rod is fixedly connected to the rotating sleeve, and the push rod end of the electric push rod is fixedly connected to the bolt. The elongation or contraction of the electric push rod can quickly and accurately insert or disengage the bolt from the card slot of the turntable, so that the rotating sleeve fixedly connected to the electric bolt can rotate synchronously with the rotation of the main shaft, thereby realizing the switching of the working state of the raceway beam on this rotating sleeve.

[0008] In a possible implementation manner, the electric bolt further includes a guide sleeve. The guide sleeve is arranged below the electric push rod and is fixedly connected to the rotating sleeve. A guide groove is provided on the inner wall of the guide sleeve, and a part of the bolt slides in the guide groove. Through the setting of the guide sleeve, the guide sleeve restricts the movement track of the bolt in the electric bolt, so that the bolt can quickly and accurately insert into the card slot.

[0009] In a possible implementation manner, a plurality of the card slots are evenly arranged on the turntable along the circumferential direction. A plurality of card slots are evenly arranged on the turntable along the circumferential direction, which is convenient for the corresponding bolt to insert into the card slot, so as to realize the synchronous rotation of the rotating sleeve with the turntable.

[0010] In a possible implementation manner, the mounting plate includes a vertical plate and a horizontal plate. The vertical plate is arranged above the horizontal plate and is fixedly connected to the rotating sleeve. One end of the horizontal plate is fixedly connected to the rotating sleeve, and the other end of the horizontal plate extends towards the auxiliary column direction, and the horizontal plate is used to support the raceway beam. The horizontal plate is used to support the raceway beam, and the vertical plate is used to limit the position of the raceway beam on the horizontal plate, so as to realize that the raceway beam can be accurately installed on the mounting plate.

[0011] In a possible implementation, a rib plate is provided on the lower surface of the cross plate. One end of the rib plate is fixedly connected to the lower surface of the cross plate, and the other end of the rib plate is fixedly connected to the rotating sleeve. The cross plate needs to support the raceway beam. By providing the rib plate, the supporting force of the cross plate is increased, making the support of the cross plate more stable.

[0012] In a possible implementation, an upper mounting portion and a lower mounting portion are provided on the side wall of the main column.

[0015] According to an embodiment of the present invention, on the other hand, a long rail transport vehicle is provided, including: a vehicle body and the above-mentioned raceway beam support assembly. The long rail transport vehicle composed of the above-mentioned raceway beam support assembly and the vehicle body has low manufacturing and operation and maintenance costs, and high working efficiency in switching the working state and the non-working state of the raceway beam.

[0016] The raceway beam support assembly and the long rail transport vehicle provided by the present invention can first control the electric plug on the rotating sleeve to insert into the card slot of the rotating disc firmly connected to the main shaft through the configured controller, and then control the driving motor to drive the main shaft on the support to rotate, so as to drive the rotating disc to rotate synchronously, thereby enabling the rotating sleeve connected to the rotating disc through the electric plug to rotate synchronously, realizing the switching of the working state of the raceway beam on the rotating sleeve.

[0048] Through the above - mentioned drawings, specific embodiments of the present disclosure have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present disclosure in any way, but to illustrate the concept of the present disclosure to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0049] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0050] The roller beam support is an important part of the long rail transport vehicle. Through the roller beam support, long rails can be placed on the long rail transport vehicle one by one so as to transport these long rails. The existing roller beam support includes a main column and a secondary column, which are respectively installed on both sides of the body of the long rail transport vehicle; wherein the main column is provided with a parallel main shaft and multiple layers of rotatable roller beams are provided along the up and down directions, and multiple rotating sleeves that can rotate around the main shaft are sleeved on the main shaft, and each layer of roller beams is fixed to a rotating sleeve through a crank connecting rod, and each rotating sleeve is driven to rotate by a separate hydraulic cylinder.

[0051] Specifically, when the hydraulic cylinder piston reciprocates, it pushes the crank to move, and the crank is fixedly connected to the rotating sleeve, thereby realizing the rotation of the rotating sleeve relative to the column, and then driving the raceway beam installed on the rotating sleeve to switch between the working state and the non-working state.

[0052] Since each swivel sleeve is currently driven by a separate hydraulic cylinder, it is necessary to arrange multiple corresponding hydraulic oil circuits and multiple hydraulic pumps corresponding to the hydraulic cylinders, which makes the manufacturing and operation and maintenance costs of the long rail transport vehicle high. In addition, since each layer of the roller beam is driven by a separate hydraulic cylinder, it is inevitable that the working efficiency of the roller beam will be low when switching the working state.

[0053] The present disclosure provides a long rail transport vehicle, which includes a vehicle body and a plurality of roller beam support assemblies installed on the vehicle body. The roller beam support assemblies are arranged on the vehicle body at intervals along the length direction of the vehicle body, wherein each group of roller beam support assemblies includes a main column and a secondary column, the main column can be fastened and installed on the left or right side of the vehicle body by welding or screwing, and correspondingly, the main column can be fastened and installed on the right or left side of the vehicle body by welding or screwing.

[0054] A plurality of mounting plates rotatable relative to the main column are mounted on the main column from top to bottom. The mounting plates are used to mount the roller beam, so that the roller beam can also rotate relative to the main column along with the mounting plates, so that the roller beam can switch between a non-working state parallel to the length direction of the vehicle body and a working state perpendicular to the length direction of the vehicle body. A bridging platform for bridging the mounting plates is provided on the secondary column. When the roller beam rotates from the non-working state to the working state, the free end of the mounting plate can be bridging the bridging platform, so as to well support the roller beam and the long steel rail mounted on the roller beam.

[0055] On the main column of this embodiment, a driving mechanism including a driving motor is also installed to drive all the mounting plates on the main column to rotate relative to the main column, thereby changing the state of the raceway beam. For example, assume that the mounting plate and the rolling beam are currently in a non-working state, that is, at this time, the mounting plate and the raceway beam are parallel to the length direction of the vehicle body; if the raceway beam needs to be switched to the working state, the above driving mechanism can be used to drive the mounting plate to rotate 90° clockwise or counterclockwise, so that the mounting plate and the rolling beam rotate relative to the main column to be perpendicular to the length direction of the vehicle body, so that long steel rails can be installed on the raceway beam; if the raceway beam is no longer needed at present, the driving mechanism can be used to drive the mounting plate to rotate 90° counterclockwise or clockwise, so as to rotate the mounting plate and the raceway beam to a position parallel to the vehicle body, that is, to switch the raceway beam from the working state to the non-working state.

[0056] In this embodiment, a separate electric locking mechanism is provided for each mounting plate. The electric locking mechanism can lock its corresponding mounting plate and the column, so that the mounting plate cannot rotate relative to the column. Of course, the electric locking mechanism can also unlock the mounting plate and the column, so that the mounting plate can rotate relative to the column, so as to switch between the working state and the non-working state. In other words, each layer of mounting plates on the column can be individually locked and unlocked with the column through their respective electric locking mechanisms, so that the state of the raceway beam on each layer of mounting plates can be switched according to actual needs during use.

[0057] This embodiment is also configured with a controller communicatively connected to the driving motor of the driving mechanism and the electric components of the electric locking mechanism. By controlling the electric locking mechanism and the driving mechanism through the controller, the switching of the state of the raceway beam on each layer of mounting plates can be automatically controlled.

[0058] For the raceway beam support assembly provided in this embodiment, since an electric driving mechanism including a driving motor and an electric locking mechanism are used, and the electric driving mechanism and the electric locking mechanism are controlled by a controller, there is no need to set up complex hydraulic pipelines, thereby reducing the manufacturing and maintenance costs of the raceway beam support assembly and the long steel rail transport vehicle, and also improving the operation efficiency of the long steel rail transport vehicle.

[0059] For example, assume that the uppermost raceway beam currently in the working state needs to be switched to the non-working state. It only needs to unlock the electric locking mechanism of the mounting plate and the main column for locking this raceway beam, and then drive the mounting plate to rotate 90° through the electric drive mechanism. Another example, assume that when the lowermost raceway beam currently in the non-working state needs to be switched to the working state, it only needs to unlock the electric locking mechanism of the mounting plate and the main column for locking this raceway beam, and then drive the mounting plate to rotate 90° through the electric drive mechanism. Another example, assume that the working states of multiple rolling beams need to be switched. It only needs to unlock the electric locking mechanisms for locking these raceway beams, and then the mounting plate can be driven to rotate through the electric drive mechanism.

[0060] The following combines the accompanying drawings to introduce the typical implementation manners of the present invention, so that those skilled in the art can more clearly understand the solution of the present disclosure. It should be noted that some or certain structures in the different implementation manners introduced below can be mutually replaced, and the implementation manners of the present disclosure are not limited to the following examples. Under the above concept, those skilled in the art can also obtain other possible implementation manners according to the examples below, and these implementation manners should also be regarded as the content of the present disclosure.

[0061] Figure 1 It is a structural schematic diagram of a raceway beam support assembly provided for this embodiment, and it also schematically shows the positions of the raceway beam in the working state and the non-working state; Figure 2 is Figure 1 a cross-sectional view of the partial structure of the raceway beam support assembly in Figure 1 and Figure 2 As shown in

[0062] A main column 10 is provided with a main shaft 20 and a driving motor 70 for driving the main shaft 20 to rotate. A plurality of rotating sleeves 30 are sleeved on the main shaft 20 from top to bottom, and each rotating sleeve 30 can rotate around the main shaft 20. An installation plate 50 and an electric bolt 60 are provided on each rotating sleeve 30. Among them, the installation plate 50 is used for installing a raceway beam 80, and the electric bolt 60 is fixedly connected to the rotating sleeve 30. A turntable 40 is provided above or below each rotating sleeve 30. Each turntable 40 is fixedly connected to the main shaft 20, and a plurality of card slots are provided on the edge of each turntable 40. Each electric bolt 60 can cooperate with a turntable 40 above or below it. Specifically, the electric bolt 60 can be inserted into the card slot of the turntable 40 that cooperates with it to lock the turntable 40 and the rotating sleeve 30 where the electric bolt 60 is installed, so that the rotating sleeve 30 can rotate together with the turntable 40. And the electric bolt 60 can also be disengaged from the card slot, so that the turntable 40 and the rotating sleeve 30 where the electric bolt 60 is installed are unlocked, and thus the rotating sleeve 30 does not rotate with the turntable 40.

[0063] The driving motor 70 and the electric bolt 60 are electrically connected to a controller, so as to control the working states of the driving motor 70 and the electric bolt 60 through the controller to flexibly control the rotating state of each layer of installation plate 50. For example, when it is necessary to adjust the raceway beam 80 on a certain layer of rotating sleeve 30, the controller controls the electric bolt 60 located on the rotating sleeve 30 to insert into the card slot above or below it, and then the driving motor 70 rotates. Then, the driving motor 70 drives the installation plate 50 to rotate through the main shaft 20, the turntable 40, the electric bolt 60 and the rotating sleeve 30, so as to realize the rapid switching between the working state and the non-working state of the raceway beam 80.

[0064] The raceway beam support assembly provided in this embodiment drives the rolling beam 80 to switch between the working state and the non-working state in an electric control manner, avoiding the use of a large number of hydraulic cylinders and reducing the manufacturing cost of the rail transport vehicle. In addition, since the controller controls the electric bolt 60 on the rotating sleeve 30 to insert into the card slot of the turntable 40 fixedly connected to the main shaft 20, and then the controller controls the driving motor 70 to drive the main shaft 20 on the support to rotate. After the main shaft 20 rotates, it drives the turntable 40 to rotate synchronously, so that the rotating sleeve 30 fixed to the turntable 40 rotates, realizing the synchronous rotation of the installation plate 50 installed on the rotating sleeve 30 and the raceway beam 80 installed on the installation plate 50, thereby changing the working state of the raceway beam 80, which is beneficial to improving the working efficiency when the working state of the raceway beam 80 is switched.

[0065] Figure 3 is Figure 2 a partial structure enlarged view; Figure 4 is Figure 3 a partial structure enlarged view. As Figure 3 and Figure 4As shown in the figure, there are three rotating sleeves 30 provided on the main shaft 20, and each sleeve 30 can rotate around the main shaft 20. An installation plate 50 is provided on each sleeve 30, and the installation plate 50 is used to install the raceway beam 80. In addition, an electric bolt 60 is provided on each sleeve 30. A turntable 40 is provided below each rotating sleeve 30. The turntable 40 is fixedly connected to the main shaft 20, and a card slot is provided on the turntable 40. When the electric bolt 60 is inserted into the card slot of the turntable 40 below it, the sleeve 30 and the turntable 40 can rotate synchronously. When the electric bolt 60 disengages from the card slot of the turntable 40 below it, the sleeve 30 does not rotate with the turntable 40.

[0066] Specifically, when it is necessary to adjust the working state of the topmost first-layer raceway beam 80, first, the electric bolt 60 of the topmost first-layer sleeve 30 needs to be inserted into the card slot provided on the turntable 40 below it. Then, the main shaft 20 is driven to rotate by the drive motor 70 (see Figure 2 ), so as to drive the turntable 40 and the sleeve 30 to rotate synchronously by 90°, so that the raceway beam 80 on the installation plate 50 rotates to the working state or the non-working state. In this way, the switching of the working state of the raceway beam 80 of this layer is realized. The working modes of the second-layer and third-layer installation plates 50 below the first-layer installation plate 50 are similar to that of the first-layer installation plate 50, and will not be elaborated here.

[0067] Please continue to refer to Figure 4 , in some implementation manners, the rotating sleeve 30 can be connected to the main shaft 20 through a bearing, so that each rotating sleeve 30 can rotate around the main shaft 20. A turntable 40 is provided below each rotating sleeve 30. Of course, a turntable 40 can also be provided above each rotating sleeve 30. The turntable 40 and the main shaft 20 can be fixedly connected by a flat key. Three evenly distributed card slots are provided on the outer edge of the turntable 40. An installation plate 50 is provided on the left side wall of the rotating sleeve 30, and the installation plate 50 is used to install the raceway beam 80. An electric bolt 60 is provided on the right side wall of the rotating sleeve 30, and the electric bolt 60 is used to insert into the card slot of the turntable 40 below it, so as to realize the synchronous rotation of the rotating sleeve 30 and the main shaft 20.

[0068] In some implementations, the electric bolt 60 on the upper swivel sleeve 30 is used in cooperation with a separate turntable 40, which can be located, for example, at the uppermost part of the main shaft 20; while the electric bolts 60 of the middle and lower swivel sleeves 30 share a single turntable 40, which can be located, for example, between these two swivel sleeves 30. The electric bolt 60 of the lower swivel sleeve 30 extends upward, and the electric bolt 60 of the middle swivel sleeve 30 extends downward. Both the electric bolt 60 of the lower part and the electric bolt 60 of the middle part can be inserted into different or the same card slots of the turntable 40 between them. In this way, when the raceway beam 80 on the upper swivel sleeve 30 needs to switch its working state, it is only necessary to insert the electric bolt 60 on this swivel sleeve 30 into the upper turntable 40, and then rotate the main shaft 20. At this time, when the swivel sleeve 30 rotates 90°, the switching of the working state of the raceway beam 80 on this swivel sleeve 30 can be achieved. The same method is also used for the middle swivel sleeve 30 and the lower swivel sleeve 30 to switch the working state of the raceway beam 80 on the corresponding swivel sleeve 30.

[0069] It should be noted that the initial state of the raceway beam 80 can be a non-working state, that is, the raceway beam 80 is parallel to the length direction of the vehicle body. When it is necessary for the raceway beam 80 to support the long rail, that is, to adjust the raceway beam 80 to the working state, it is necessary to rotate the raceway beam 80 to be perpendicular to the length direction of the vehicle body. Generally speaking, during the unloading process of the long rail, it is necessary to unload the upper long rail first, and then unload the long rail on the second upper layer, unloading the long rail from the upper layer to the lower layer in sequence. Therefore, it is necessary to adjust the working state and non-working state of the raceway beams 80 on each layer multiple times.

[0070] Among them, the starting positions of the raceway beams 80 can all be configured as non-working states, for example. When it is necessary to adjust the raceway beams 80 to the working state, in this embodiment, it is only necessary to insert the electric bolt 60 on the upper swivel sleeve 30 into the card slot of the upper turntable 40. Since there is no load in the non-working state, at this time, the electric bolt 60 on the lower swivel sleeve 30 can be inserted into the lower part of the card slot of the lower turntable 40, and the electric bolt 60 on the middle swivel sleeve 30 can be inserted into the upper part of the card slot of the lower turntable 40. That is, the electric bolts 60 in the lower swivel sleeve 30 and the middle swivel sleeve 30 are both inserted into the lower turntable 40. Then, by driving the main shaft 20 to rotate, the raceway beams 80 on multiple layers are synchronously switched to the working state, improving the efficiency of switching from the non-working state to the working state.

[0071] When unloading the long rail, it is necessary to insert the electric bolt 60 corresponding to the topmost raceway beam 80 into the corresponding turntable 40, and then drive the main shaft 20 to rotate to switch the raceway beam 80 of this layer to the non-working state; when it is necessary to unload the long rail on the second top layer, it is necessary to insert the electric bolt 60 corresponding to the raceway beam 80 of the second top layer into the corresponding turntable 40, and then drive the main shaft 20 to rotate to switch the raceway beam 80 of this layer to the non-working state. The unloading methods of the raceway beams 80 on other layers for the long rail are the same as the above-mentioned unloading method, which will not be elaborated here.

[0072] Please refer to Figure 4 , the mounting plate 50 is fixedly connected to the rotating sleeve 30. The middle part of the rotating sleeve 30 is rotatably connected to the main shaft 20 through a bearing. The raceway beam 80 is fixedly connected to the mounting plate 50. The shaft sleeve 30 and the mounting plate 50 can be fixedly connected by welding. Thus, when the rotating sleeve 30 rotates, the raceway beam 80 on the mounting plate 50 can be driven to rotate accordingly to realize the switching between the working state and the non-working state of the raceway beam 80.

[0073] Specifically, the mounting plate 50 includes a vertical plate 501 and a horizontal plate 502, and both the vertical plate 501 and the horizontal plate 502 can be made of steel plates; among them, the vertical plate 501 is arranged above the horizontal plate 502 and is fixedly connected to the rotating sleeve 30. One end of the horizontal plate 502 is fixedly connected to the rotating sleeve 30, and the other end of the horizontal plate 502 extends towards the auxiliary column 90. The horizontal plate 502 is used to support the raceway beam 80. Both the vertical plate 501 and the horizontal plate 502 can be fixedly connected to the rotating sleeve 30 by welding. By fixedly connecting the horizontal plate 502 to the rotating sleeve 30, the horizontal plate 502 can rotate synchronously with the rotating sleeve 30. Through the arrangement of the horizontal plate 502 and the vertical plate 501, the raceway beam 80 mounted on the mounting plate 50 can be limited. When the raceway beam 80 switches from the non-working state to the working state, the horizontal plate 502 needs to support the long rail on the raceway beam 80. Therefore, after the horizontal plate 502 rotates through the rotating sleeve 30, it overlaps with the auxiliary column 90 so that the horizontal plate 502 has sufficient supporting force to support the long rail on the raceway beam 80.

[0074] Figure 5 For Figure 4 the left view. As Figure 4 and Figure 5As shown, in some implementations, a rib plate 503 is provided on the lower surface of the cross plate 502. The rib plate 503 can be a steel plate. One end of the rib plate 503 is fixedly connected to the lower surface of the cross plate 502, and the other end of the rib plate 503 is fixedly connected to the rotating sleeve 30. The cross plate 502 supports the raceway beam 80. By providing the rib plate 503 on the lower surface of the cross plate 502, the supporting force of the cross plate 502 on the raceway beam 80 is further increased, making the raceway beam 80 more stable on the cross plate 502. In this embodiment, the number of rib plates 503 can be three. One rib plate 503 is provided at the center of the cross plate 502, and the other two rib plates 503 are provided at both ends of the cross plate 502. One end of the rib plate 503 can be fixedly connected to the lower surface of the cross plate 502 by welding, and the other end of the rib plate 503 can be fixedly connected to the rotating sleeve 30 by welding. Of course, the number of rib plates 503 is only illustrative, and in other embodiments, it can be any other number.

[0075] Figure 6 The structure of an electric bolt is shown. As Figure 6 shown, the electric bolt 60 includes an electric push rod 601 and a bolt 602. The electric push rod 601 is fixedly connected to the rotating sleeve 30. The push rod end of the electric push rod 601 is fixedly connected to the bolt 602. The electric bolt 60 is electrically connected to the controller. The electric push rod 601 can be composed of a push rod motor, reduction gears, a screw, a nut, a guide sleeve, a push rod, a sliding seat, a spring, a housing, a turbine, a micro motion control switch, etc. It is a power-driven device that converts the rotational motion of an electric motor into the linear reciprocating motion of a push rod. The bolt 602 can be, for example, a long strip-shaped steel block so that the bolt 602 can be inserted into the card slot of the turntable 40.

[0076] Since the electric push rod 601 is fixedly connected to the rotating sleeve 30, when the controller controls the micro motion control switch of the electric bolt 60 to insert the bolt 602 at the push rod end of the electric push rod 601 into the corresponding card slot of the turntable 40, the turntable 40 and the rotating sleeve 30 are connected together. The turntable 40 rotates with the main shaft 20. At this time, the rotating sleeve 30 will also rotate with the main shaft 20, so that the rotation of the main shaft 20 can drive the raceway beam 80 on the rotating sleeve 30 to quickly switch between the working state and the non-working state.

[0077] Specifically, the electric push rod 601 and the rotating sleeve 30 can be fixedly connected by means of bolt fastening. The push rod end of the electric push rod 601 and the bolt 602 can also be fixedly connected by means of bolt fastening. The electric push rod 601 is fixedly connected to the rotating sleeve 30 and the electric push rod 601 is fixedly connected to the bolt 602, so that the bolt 602 of the electric push rod 601 is inserted into the card slot of the turntable 40, realizing that the rotating sleeve 30 can rotate synchronously with the turntable 40.

[0078] It should be noted that the electric push rod 601 and the rotating sleeve 30 are fixedly connected by means of bolts, which is only a schematic way. The electric push rod 601 and the rotating sleeve 30 can also be fixedly connected by other ways that can be fixed together, such as welding. The push rod end of the electric push rod 601 and the pin 602 are fixedly connected by means of bolts, which is also a schematic way. The push rod end of the electric push rod 601 and the pin 602 can also be fixedly connected by other ways that can be fixed together, such as welding.

[0079] In some realizable ways, the electric plug 60 further includes a guide sleeve 603. The guide sleeve 603 is arranged below the electric push rod 601 and the guide sleeve 603 is fixedly connected to the rotating sleeve 30. A guide groove is provided on the inner wall of the guide sleeve 603, and a part of the pin 602 slides in the guide groove, so that the pin 602 moves along the trajectory preset by the guide groove, improving the accuracy of the pin 602 inserted into the card slot of the turntable 40. The guide sleeve 603 can be fixedly connected to the rotating sleeve 30 by welding or by means of bolt fastening. In this embodiment, the guide sleeve 603 is fixedly connected to the rotating sleeve 30 by welding.

[0080] Figure 7 Shows the structure of a turntable. As Figure 7 shown, a mounting hole is opened in the middle of the turntable 40 and two key grooves are opened in the mounting hole. A flat key is installed in the key groove in the turntable 40, and the turntable 40 is fixedly connected to the main shaft 20. A stepped shaft is provided outside the mounting hole of the turntable 40, which is convenient for installing bearings. Three card slots 401 are provided on the outer edge of the turntable 40. The three card slots 401 are evenly arranged on the turntable 40. The three card slots 401 are evenly arranged specifically by evenly distributing the three card slots 401 on the turntable 40 at equal intervals. In this way, when the card slots 401 on the turntable 40 switch working states on different layers of the raceway beams 80, each layer of the raceway beam 80 will correspond to a turntable 40. When adjusting a certain layer of the raceway beam 80, the turntables 40 of the other two layers will also rotate synchronously. The evenly arranged card slots 401 on the turntable 40 can make the turntables 40 of the other two layers rotate synchronously when adjusting a certain layer. At this time, the card slots 401 on the turntables 40 of the other two layers can still make the pins 602 of the corresponding electric plugs 60 inserted into the card slots 401, avoiding readjusting the centering of the card slots 401 and the corresponding pins 602 and improving the efficiency.

[0081] It should be noted that Figure 7 the number of the card slots 401 shown on the turntable 40 is only schematic, and of course, the specific number can be determined according to the specific structure of the bracket on the vehicle body.

[0082] Figure 8Shows the structure of a main column. As Figure 8 shown, on the side wall of the main column 10, there are an upper mounting portion 101 and a lower mounting portion 102. An upper fixing sleeve 103 is mounted on the upper mounting portion 101, and a lower fixing sleeve 104 is mounted on the lower mounting portion 102. The main shaft 20 passes through the upper fixing sleeve 103 and the lower fixing sleeve 104 and is fixedly connected to the upper fixing sleeve 103 and the lower fixing sleeve 104.

[0083] Optionally, both the upper mounting portion 101 and the lower mounting portion 102 are ear plates extending outwards. Then, the upper fixing sleeve 103 and the lower fixing sleeve 104 are fixedly connected to each ear plate by bolts. Among them, the upper fixing sleeve 103 and the lower fixing sleeve 104 can be bearing sleeves, and the upper and lower ends of the main shaft 20 can be mounted in the upper fixing sleeve 103 and the lower fixing sleeve 104.

[0084] By respectively arranging the upper end and the lower end of the main shaft 20 in the upper fixing sleeve 103 and the lower fixing sleeve 104 on the main column 10, the main shaft 20 is rotatably mounted in the main column 10. There is a certain space between the main shaft 20 and the main column 10 through the upper mounting portion 101 and the lower mounting portion 102 on the side wall of the main column 10, which is convenient for the installation of other parts.

[0085] Figure 9 Shows the structure of a secondary column. As Figure 9 shown, on the secondary column 90, there is a lapping platform 901, and the lapping platform 901 is used for lapping the mounting plate 50. By providing the lapping platform 901 on the secondary column 90, it is convenient to support and limit the free end of the mounting plate 50 when the raceway beam 80 provided on the mounting plate 50 switches to the working state, so that the long rail can be stably placed on the raceway beam 80.

[0086] A spring pin can be provided on the lapping platform 901. So that when the raceway beam 80 contacts the lapping platform 901, the spring pin can be compressed first. When the whole mounting plate 50 passes over the spring pin, the spring pin pops up and catches the mounting plate 50, so that the raceway beam 80 on the mounting plate 50 can be stably placed on the lapping platform 901. When switching the working state to the non - working state, rotate the cross - plate 502 in the reverse direction so that the mounting plate 50 compresses the spring pin. When the whole mounting plate 50 passes over the spring pin, the spring pin pops up and the mounting plate 50 is separated from the lapping platform 901.

[0087] Figure 10 Shows a transmission mechanism. As Figure 10As shown in the figure, the transmission mechanism may include a driving motor 70, a reducer 100, an elastic coupling 110, a transmission shaft 120, and a gear 130. The controller is electrically connected to the driving motor 70. By controlling the driving motor 70 to rotate, the power of the driving motor 70 is transmitted to the main shaft 20 through the reducer 100, the elastic coupling 110, the transmission shaft 120, and the gear 130. The driving motor 70 is a forward and reverse motor. When the driving motor 70 rotates forward, it drives the main shaft 20 to rotate forward, providing power for the raceway beam 80 to switch from the non-working state to the working state. When the driving motor 70 rotates in reverse, it drives the main shaft 20 to rotate in reverse, providing power for the raceway beam 80 to switch from the working state to the non-working state.

[0088] Optionally, the gear 130 is a bevel gear; the raceway beam support assembly further includes a bearing seat 140 for supporting the transmission shaft 120. The bevel gear has the advantages of stable operation, large torque, high load-bearing capacity, high transmission efficiency, etc., so that the transmission between the transmission shaft 120 and the main shaft 20 through the bevel gear is stable and efficient; by arranging the bearing seat 140 on the transmission shaft 120, the transmission between the transmission shaft 120 and the main shaft 20 is smooth and has high precision. Of course, other types of gears can also be selected for the gear 130 as long as the transmission requirements are met.
