When the tractor travels along a double-track track, the front axle assembly 110 and the rear axle assembly 120 are connected as a whole; the traction assembly 20 is fixed to the bottom of the front axle assembly 110, and includes a drive motor 210 and a wheel axle 220 perpendicular to the traveling direction, and the drive motor 210 is used to drive the wheel The shaft 220 rotates, and the wheel shaft 220 is rotatably fixed to the bottom surface of the front axle assembly 110; the wheel assembly 30 includes a driving wheel group 310 and a driven wheel group 320, the driving wheel group 310 is fixed to both ends of the wheel shaft 220, and the driven wheel group 320 is rotatably fixed to both sides of the bottom surface of the rear axle assembly 120, and the rotating shaft of the driven wheel group 320 is parallel to the axis of the wheel shaft 220; the battery assembly 40 is electrically connected to the control assembly 50, and is configured to supply power to the control assembly 50 and to supply power to the drive motor 210 through the control assembly 50; the control assembly 50 is used to control the operating state of the drive motor 210 to control the driving state of the tractor.

[0032] In this embodiment, the control component 50 may include a main control circuit board and a driver for the drive motor 210. The main control circuit board is connected to the driver to control the operation state of the drive motor 210. The control circuits of other components may be integrated on the main control circuit board, such as the control circuits of the ball camera component 80 and the joystick 90, wherein the ball camera component 80 is used to collect video during the movement of the tractor, and the joystick 90 is used by the staff to control the direction of travel of the tractor. The battery component 40 is electrically connected to the control component 50 through a wire, and the current is input into the main control circuit board, and the main control circuit board inputs the current into each control circuit and the driver to realize the control of the tractor.

[0033] In practice, workers usually use tractors to conduct track inspections, and use various detection equipment to detect the track, such as flaw detection, while the tractor is moving along the track. The control component 50 may further be provided with an external power supply interface, which is connected to a transformer circuit or a rectifier circuit on the main control circuit board to access a preset voltage or current, so that the detection equipment can be powered.

[0034] In this embodiment, the body 10 of the tractor is used to carry other components and staff. The body 10 is divided into a front axle assembly 110 and a rear axle assembly 120 along the traveling direction of the tractor. The front axle assembly 110 may include the front part of the tractor, and the rear axle assembly 120 may include the rear part of the tractor. Other components of the tractor may be arranged on the front axle assembly 110 or the rear axle assembly 120. For example, the rocker 90, the ball machine assembly 80, and the brake assembly 70 may be arranged on the front axle assembly 110, and the seat may be arranged on the rear axle assembly 120. For another example, the battery assembly 40 and the control assembly 50 may also be arranged on the front axle assembly 110 or the rear axle assembly 120, or separately.

[0035] The front axle assembly 110 and the rear axle assembly 120 adopt a detachable connection structure, for example, the connection structure of the traction pin and the traction plate in the semi-trailer can be adopted. In this way, the vehicle body 10 can be split or connected according to actual needs. For example, when the tractor needs to be put on or off the track, the connection between the front axle assembly 110 and the rear axle assembly 120 can be disconnected, and then the front axle assembly 110 and the rear axle assembly 120 can be moved off the track respectively. When the tractor needs to be driven on the track, the front axle assembly 110 and the rear axle assembly 120 can be moved to the track respectively, and then the front axle assembly 110 and the rear axle assembly 120 can be connected as a whole. For reference Figure 3 , Figure 3 A schematic diagram of the overall structure of an embodiment of a tractor disclosed herein in a connected state is shown.

[0036] In this embodiment, the traction assembly adopts a single-motor dual-output shaft power output method, and the driven wheel group adopts a broken-arm type with separate loads on both sides.

[0037] The tractor provided by the embodiment of the present disclosure adopts a split vehicle body 10. When the tractor moves along the track, the front axle assembly 110 and the rear axle assembly 120 are connected as a whole, and the tractor can travel normally. When the tractor needs to go up or down the track, the connection between the front axle assembly 110 and the rear axle assembly 120 can be disconnected, and the front axle assembly 110 and the rear axle assembly 120 can be operated separately, without the need to operate the operation of going up or down the track at a designated operation location, thereby improving the flexibility of the tractor going up or down the track.

[0038] Reference below Figure 4 , Figure 4 A cross-sectional view of the connection between the front axle assembly 110 and the rear axle assembly 120 in one embodiment of the tractor of the present disclosure is shown. Figure 4As shown, a first connection surface is provided on the chassis of the front axle assembly 110, and a guide hole 111 is formed on the first connection surface, and the axis of the guide hole 111 is the same as the direction of travel; a vertical mounting hole 113 is formed on the chassis of the front axle assembly 110, and the portion of the mounting hole 113 located below the guide hole 111 is provided with a thread; a second connection surface is provided on the chassis of the rear axle assembly 120, and a connecting shaft 121 extending outwardly along the direction of travel is formed on the second connection surface, and a vertical through hole is formed on the connecting shaft 121, and the second connection surface is in contact with the first connection surface, The connecting shaft 121 extends into the guide hole 111, and the through hole is concentric with the mounting hole; the tractor also includes a connecting assembly 60, which includes a locking bolt 610, a locking chain (not shown in the figure) and an anti-slip bolt 620. The end face of the bolt head of the locking bolt 610 is formed with a threaded hole, and the locking bolt 610 passes through the mounting hole and the through hole to engage with the thread of the mounting hole; the first end of the locking chain is fixed to the chassis of the rear axle assembly 120, and the anti-slip bolt 620 passes through the second end of the locking chain to engage with the threaded hole of the bolt head of the locking bolt 610.

[0039] An example is given in combination with a specific application scenario. When the tractor needs to be put on track, the front axle assembly 110 and the rear axle assembly 120 can be placed on the horizontal straight track respectively, and then the front axle assembly 110 or the rear axle assembly 120 can be moved, and the connecting shaft 121 can be inserted into the guide hole 111 until the first connecting surface is in contact with the second connecting surface, and then the locking bolt 610 can be inserted into the mounting hole 113, so that the locking bolt 610 passes through the through hole on the connecting shaft 121 and engages with the threaded portion at the lower part of the mounting hole 113. After that, the second end of the locking chain is sleeved on the anti-detachment bolt 620, and the anti-detachment bolt 620 is fixed in the threaded hole of the bolt head of the locking bolt 610, so that the front axle assembly 110 and the rear axle assembly 120 are connected as a whole. After that, the power supply assembly and the control assembly 50, as well as the control assembly 50 and the operation panel can be connected through the wiring harness to complete the operation of putting the tractor on track. When the tractor needs to get off the track, the tractor can be driven onto a horizontal track and the front axle assembly 110 can be locked by the brake assembly 70, and then the wiring harness between the power assembly and the control assembly 50 and between the control assembly 50 and the operation panel can be disconnected, and then the locking bolt 610 can be removed from the mounting hole 113, and the rear axle assembly 120 can be moved so that the connecting shaft 121 is partially disengaged from the guide hole 111, and then the anti-detachment bolt 620 can be removed from the threaded hole of the bolt head of the locking bolt 610, and the connection between the locking chain and the front axle assembly 110 can be disconnected, and the rear axle assembly 120 can be moved again so that the connecting shaft 121 is completely disengaged from the guide hole 111, and the separation of the tractor body 10 can be completed, and finally the rear axle assembly 120 and the front axle assembly 110 can be moved off the track respectively, and the tractor can be completed from the track.

[0040] Furthermore, a conical guide structure is provided at one end of the guide hole 111 close to the first connection surface and at the end of the connecting shaft 121 away from the second connection surface. The conical guide structure can guide the connecting shaft 121 to be inserted into the guide hole 111, thereby reducing the difficulty of connecting the front axle assembly 110 and the rear axle assembly 120.

[0041] It is understandable that the guide hole 111 in this embodiment can also be set on the chassis of the rear axle assembly 120, the connecting shaft 121 can also be set on the front axle assembly 110, and the first end of the locking chain can be fixed on the chassis of the front axle assembly 110. In addition, multiple groups of guide holes 111 and connecting shafts 121 can be set according to actual needs, and this application does not limit this.

[0042] The tractor in this embodiment can realize the rapid disassembly of the front axle assembly 110 and the rear axle assembly 120 by respectively providing the connecting shaft 121 and the guide hole 111 on the front axle assembly 110 and the rear axle assembly 120, and fixing the connecting shaft 121 in the guide hole 111 by the locking bolt 610. Moreover, when disconnecting, the locking chain can prevent the safety hazard caused by the connecting shaft 121 being completely separated from the guide hole 111 at one time, thereby improving the safety during operation.

[0043] Next reference Figure 3 In some optional implementations of the present embodiment, the front axle assembly 110 is formed with a first accommodating cavity 112 on the side away from the first connecting surface, the first accommodating cavity 112 is used to accommodate the control assembly 50, the opening direction of the first accommodating cavity 112 is the same as the traveling direction, and a wiring window is provided on the side of the first accommodating cavity 112 opposite to the opening.

[0044] In this implementation, the control assembly 50 can be placed in the first accommodating chamber 112, and then the wiring or disconnection operation of the control assembly 50 can be realized through the wiring window. In this way, the control assembly 50 can be quickly installed and removed. When the tractor is mounted on or off the track, the control assembly 50 can be first taken out of the first accommodating chamber 112, which can reduce the weight of the vehicle body.

[0045] Further integration Figure 5 , Figure 5 FIG. 1 shows a schematic diagram of the structure of the first accommodation chamber 112 in an embodiment of a tractor. Figure 5 As shown, a first guide plate 114 is provided at the connection between the bottom surface of the first accommodating cavity 112 and the two side walls. The first guide plate 114 is a plate-like structure with an "L"-shaped cross-section, and extends toward the interior of the first accommodating cavity 112 along the depth direction of the first accommodating cavity 112. The two outer planes of the first guide plate 114 are simultaneously in contact with the bottom surface and side walls of the first accommodating cavity 112, so as to guide the control component 50 to be placed in or removed from the first accommodating cavity 112.

[0046] In this implementation, the first guide plate 114 can guide the control assembly 50 to be placed into or removed from the first accommodating cavity 112 to simplify the installation and removal operations of the control assembly 50 .

[0047] Furthermore, the inner plane of the first guide plate 114 can be machined into a relatively smooth plane to reduce the sliding friction between the control component 50 and the first guide plate 114 , thereby further reducing the working intensity of the mobile control component 50 .

[0048] Furthermore, a first limiting assembly 115 is also provided at the opening of the first accommodating chamber 112, and the first limiting assembly 115 includes a first blocking block and a first reset device, the first blocking block is connected to the first reset device, and the first reset device is used to drive the first blocking block to move from the second position to the first position; when the first blocking block is in the first position, the first blocking block intersects with the projection of the first accommodating chamber 112 in a plane perpendicular to the depth direction of the first accommodating chamber 112, so as to limit the movement of the control assembly 50 in the first accommodating chamber 112; when the first blocking block is in the second posture, the first blocking block does not intersect with the projection of the first accommodating chamber 112 in a plane perpendicular to the depth direction of the first accommodating chamber 112, so as to move the control assembly 50 out of the first accommodating chamber 112.

[0049] As an example, a pressing head can be used as the first limiting component 115, the stopper of the pressing head is the first stopper, and the spring in contact with the stopper is the first reset device. The pressing head is set at the bottom opening of the first accommodating chamber 112. When the control component 50 is located in the first accommodating chamber 112, the stopper of the pressing head extends upward into the opening area of ​​the first accommodating chamber 112, so as to prevent the control component 50 from sliding toward the opening. When the control component 50 needs to be taken out of the first accommodating chamber 112, the stopper can be pressed downward so that the height of the top of the stopper of the pressing head is not higher than the bottom surface of the first accommodating chamber 112, and then the control component 50 can be dragged.

[0050] Next reference Figure 3 In some optional implementations of the present embodiment, a seat 125 is fixed on the chassis of the rear axle assembly 120, and a second accommodating cavity 122 is formed under the seat 125. The second accommodating cavity 122 is used to accommodate the battery assembly 40, and the opening direction of the second accommodating cavity 122 is the same as the traveling direction.

[0051] This implementation method can realize the rapid disassembly and assembly of the battery assembly 40. When the tractor is dismounted or mounted on the track, the battery assembly 40 can be taken out from the second accommodating cavity 122 first to reduce the weight of the vehicle body.

[0052] Furthermore, a first power interface is provided on the side of the second accommodating cavity 122 opposite to the opening, and the first power interface is electrically connected to the control component 50 through a wire; a second power interface is provided on the outer shell of the battery assembly 40, and the second power interface is electrically connected to the battery assembly 40. When the battery assembly 40 is located inside the second accommodating cavity 122, the first power interface and the second power interface are in an aligned state.

[0053] In this implementation, the battery assembly 40 only needs to be pushed into the second accommodating cavity 122 to realize the connection between the first power interface and the second power interface, thereby realizing the electrical connection between the battery assembly 40 and the control assembly 50, which can simplify the connection operation of the battery assembly 40.

[0054] Further integration Figure 6 , Figure 6 FIG. 1 shows a schematic diagram of the structure of the second accommodation chamber 122 in an embodiment of a tractor. Figure 6 As shown, a second guide plate 123 is provided at the connection between the bottom surface of the second accommodating cavity 122 and the two side walls. The second guide plate 123 is a plate-like structure with an "L"-shaped cross-section, and extends toward the interior of the second accommodating cavity 122 along the depth direction of the second accommodating cavity 122. The two outer planes of the second guide plate 123 are simultaneously in contact with the bottom surface and side walls of the second accommodating cavity 122, so as to guide the battery assembly 40 into or out of the second accommodating cavity 122.

[0055] In this implementation, the second guide plate 123 can guide the battery assembly 40 to be placed into or removed from the second accommodating cavity 122 to simplify the installation and removal operations of the battery assembly 40 .

[0056] Furthermore, the inner plane of the second guide plate 123 can be processed into a relatively smooth plane through mechanical processing to reduce the sliding friction between the battery assembly 40 and the second guide plate 123, thereby further reducing the working intensity of moving the battery assembly 40.

[0057] Furthermore, a second limiting assembly 124 is also provided at the opening of the second accommodating cavity 122, and the second limiting assembly 124 includes a second blocking block and a second reset device, and the second blocking block is connected to the second reset device, and the second reset device is used to drive the second blocking block to move from the third position to the fourth position, and when the second blocking block is in the third position, the second blocking block intersects with the projection of the second accommodating cavity 122 in a plane perpendicular to the depth direction of the second accommodating cavity 122, so as to limit the movement of the battery assembly 40 in the second accommodating cavity 122, and when the second blocking block is in the fourth position, the second blocking block does not intersect with the projection of the second accommodating cavity 122 in a plane perpendicular to the depth direction of the second accommodating cavity 122, so as to move the battery assembly 40 out of the second accommodating cavity 122.

[0058] As an example, a pressing head can be used as the second limiting component 124, the stopper of the pressing head is the second stopper, and the spring in contact with the stopper is the second reset device. The pressing head is set at the top opening of the second accommodating chamber 122. When the battery assembly 40 is located in the second accommodating chamber 122, the stopper of the pressing head extends downward into the opening area of ​​the second accommodating chamber 122, thereby preventing the battery assembly 40 from sliding toward the opening. When the battery assembly 40 needs to be taken out of the second accommodating chamber 122, the stopper can be pressed upward so that the height of the end of the stopper of the pressing head is not lower than the bottom surface of the first accommodating chamber 112, and then the battery assembly 40 can be dragged.

[0059] It should be noted that the tractor in this embodiment can be provided with a first accommodating chamber and a second accommodating chamber at the same time, which are used to accommodate the control component and the battery component respectively, and the positions of the first accommodating chamber and the second accommodating chamber can be exchanged, and this application does not limit this. In this way, when the tractor is on or off the track, the control component and the battery component can be quickly disassembled to reduce the weight of the vehicle body. When the operation is completed, the control component and the battery component can be quickly placed in the first accommodating chamber and the second accommodating chamber, thereby simplifying the operation and reducing the work intensity.
