DETAILED DESCRIPTION

[0041] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] Embodiment 1:

[0044] A hydraulic self-propelled train set, such as Figures 1 to 10As shown, it includes a car body that uses a track assembly to move itself, and the two car bodies are connected by a connecting section. Lifting parts are fixed on both sides of the car body, and a bracket 2 18 is welded to the bottom of the car body, and the inner wall of the bracket 2 18 is rotatably connected to a hydraulic cylinder 3 16 through a rotating shaft, and the end of the hydraulic cylinder 3 16 away from the bracket 2 18 is rotatably connected to a bracket 15 through a rotating shaft, and the bracket 15 and the track assembly are fixedly connected, and a clamping assembly for fixing the track assembly is fixed to the bottom of the car body;

[0045] When the vehicle body needs to use the track assembly to move itself, the vehicle body and the track assembly are slidably connected. When the track assembly is laid flat on the ground, the vehicle body moves relative to the track assembly by sliding. When the vehicle body moves, its power source relies on the extension of the output end of the hydraulic cylinder three 16, that is, when the track assembly remains stationary, the output end of the hydraulic cylinder three 16 pushes the vehicle body to slide along the track assembly when it is extended. When the vehicle body moves to the end of the track assembly, the jacking piece is used to lift the vehicle body a certain distance, so that the vehicle body and the track assembly are synchronously moved up a certain distance. At this time, the output end of the hydraulic cylinder three 16 is adjusted from the extended state to the contracted state, so that the track assembly moves forward a certain distance relative to the vehicle body. When the jacking piece puts down the vehicle body and the track assembly, the vehicle body can move forward along the track assembly again in a manner similar to creeping, and the cyclic self-movement of the vehicle body is realized in this way.

[0046] The vehicle body moves by itself in this way, so that the track components can be laid flexibly, and the vehicle body does not need to move according to a fixed motion trajectory, thereby improving the flexibility of the vehicle body when moving underground.

[0047] Furthermore, the track assembly includes a lateral slide plate 14 and a track body 23, and the two lateral slide plates 14 are fixed to the top outer wall of the track body 23 by bolts;

[0048] The vehicle body is supported by the lateral slide plate 14 and the track body 23 so that the vehicle body can move by itself.

[0049] Furthermore, the vehicle body includes a frame 17 and a roller 19, the roller 19 is rotatably connected to the bottom of the frame 17, and the top outer walls of the two frames 17 are fixed with the same base 1 by bolts, and the top outer wall of the base 1 is fixed with a guardrail 2 by bolts;

[0050] When the vehicle body is moving, the two sets of rollers 19 are respectively inserted into the side walls of the two lateral slides 14, thereby limiting the position of the rollers 19. When the rollers 19 slide along the lateral slides 14, they can drive the base 1 and the guardrail 2 to move, and the base 1 can be used to place objects to be transported.

[0051] Further, the lifting member includes a hydraulic cylinder 15, a lifting plate 6 and a mounting plate 7, wherein the mounting plate 7 is fixed to the side wall of the base 1 by bolts, and the hydraulic cylinder 15 is fixed to the top outer wall of the mounting plate 7 by bolts, and the lifting plate 6 is fixed to the output end of the hydraulic cylinder 15 by a pin;

[0052] The hydraulic cylinder 5 is used to drive the lifting plate 6 to move downward. When the lifting plate 6 contacts the ground, the output end of the hydraulic cylinder 5 continues to move, so that the entire vehicle body can be lifted a certain distance.

[0053] Further, the clamping assembly includes a hydraulic cylinder 20, a receiving plate 21 and a clamping plate 22, the receiving plate 21 is welded to the inner wall of the frame 17, and the hydraulic cylinder 20 is fixed to the outer wall of one side of the receiving plate 21 by bolts, and the clamping plate 22 is fixed to the output end of the hydraulic cylinder 20 by pins;

[0054] When the vehicle body moves to the set position, the hydraulic cylinder 20 is used to drive the clamping plate 22 to move laterally, so that the clamping plate 22 is pressed against the side wall of the lateral slide plate 14, thereby improving the stability of the vehicle body relative to the track assembly.

[0055] Furthermore, the connecting section includes a connecting frame 3 and a fixing plate 9, one end of the connecting frame 3 is rotatably connected to the end of the base 1 of one of the vehicle bodies through a rotating shaft, and the fixing plate 9 is welded to the other end of the connecting frame 3, and a plug hole is opened on the surface of the fixing plate 9, and the connecting section also includes a latch member, and the latch member includes:

[0056] Connecting frame 13: It is welded to one end of the base 1 of another vehicle body;

[0057] Sleeve 8: It is fixed to one end of the connecting frame 13 by screws;

[0058] Pin 27: It is slidably connected to one end of the sleeve 8, and the pin 27 and the socket are used in conjunction with each other;

[0059] Spring 26: two ends of which are respectively clamped to the inner wall of one side of the sleeve 8 and the outer wall of one side of the pin rod 27;

[0060] Pull rod 24: It is fixed to one end of pin rod 27 by screws, and a handle 25 is fixed to one end of pull rod 24;

[0061] Locking nut 33: threadedly connected to one end of the pin rod 27;

[0062] When it is necessary to connect the two car bodies, the socket on the fixing plate 9 is moved to a position opposite to the pin rod 27, and the pin rod 27 is inserted into the inner wall of the socket by utilizing the elastic force of the spring 26. The connecting frame 3 and the connecting frame 13 are connected by utilizing the pin rod 27 and the socket, and the pin rod 27 and the connecting frame 13 can be locked by providing a locking nut 33.

[0063] Further, an offset assembly is installed on the outer wall of one side of the base 1, and the offset assembly includes a side plate 10 and a bracket 3 28. The side plate 10 is welded to one side of the base 1, and the bracket 3 28 and the side plate 10 are welded and fixed. The inner wall of the bracket 3 28 is rotatably connected to the hydraulic cylinder 2 11 through a rotating shaft, and the output end of the hydraulic cylinder 2 11 is fixed to the support block 12 through bolts. The side wall of the side plate 10 is rotatably connected to the hydraulic cylinder 5 29, and the output end of the hydraulic cylinder 5 29 and the outer wall of the hydraulic cylinder 2 11 are rotatably connected.

[0064] When the vehicle body needs to turn, the hydraulic cylinder 2 11 of one group of offset components is driven according to the turning angle and the turning direction. When the support block 12 contacts the ground, the hydraulic cylinder 2 11 is used to lift the track assembly and the vehicle body as a whole. At this time, after the output end of the hydraulic cylinder 2 11 continues to move, the track assembly and the vehicle body are offset to the left or right by a certain angle, thereby realizing the turning of the vehicle body and the track assembly.

[0065] Furthermore, a limiting column 30 is welded to the outer wall of the top of the guardrail 2, and a vertical plate 32 is welded to the end of the connecting frame 3, and a snap-on buckle 31 is rotatably connected between the two vertical plates 32;

[0066] When the connection between the two vehicle bodies needs to be disconnected, the connecting frame 3 is folded and stowed, and the snap-fit ​​buckle 31 is rotated to the inside of the limiting column 30 to ensure the stability of the connecting frame 3 .

[0067] Furthermore, a control box 4 is fixed to the outer wall of one side of the base 1 by bolts;

[0068] The control box 4 is provided with various control switches, which can control the activation of various components such as hydraulic cylinder 1 5, hydraulic cylinder 2 11, hydraulic cylinder 3 16, hydraulic cylinder 4 and hydraulic cylinder 5 29 to realize the self-movement of the vehicle body.

[0069] When this embodiment is in use, the vehicle body and the track assembly are slidably connected so that when the track assembly is laid flat on the ground, when the vehicle body is moving, the output end of the hydraulic cylinder three 16 is extended to push the vehicle body to slide along the track assembly. When the vehicle body moves to the end of the track assembly, the jacking piece is used to lift the vehicle body for a certain distance, and the vehicle body and the track assembly are synchronously moved up a certain distance. At this time, the output end of the hydraulic cylinder three 16 is adjusted from the extended state to the contracted state, and the track assembly moves forward a certain distance relative to the vehicle body. When the jacking piece puts down the vehicle body and the track assembly, the vehicle body moves forward again along the track assembly in a manner similar to creeping.
