DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Please see attached Figure 1 and attached Figure 2 A transport device for dismantling tunnel tracks comprises a vehicle body 1, tires 2, guide plates 3, traction mechanisms 4, side limit assemblies 6 and locking assemblies 7; a plurality of tires 2 are installed at intervals at the bottom of the vehicle body 1, the traction mechanism 4 is installed at the front end of the vehicle body 1, and the guide plate 3 is rotatably installed at the rear end of the vehicle body 1 through the traction mechanism 4; a pair of side limit assemblies 6 are symmetrically arranged on both sides of the vehicle body 1, each set of side limit assemblies 6 is located between the traction mechanism 4 and the guide plate 3, and the bottom of the side limit assemblies 6 is locked on the vehicle body 1 through the locking assemblies 7.

[0024] The vehicle body 1 can select a flatbed truck of corresponding specifications according to the size of the track to be transported, and the tire 2 can use rail wheels, universal wheels, etc. according to the movement requirements of the vehicle body 1 for loading and transportation on the track.

[0025] The traction mechanism 4 can be used as a limiter at the front end of the vehicle body 1 to prevent the track from sliding forward and falling, and can also be used to provide traction for the guide plate 3 to control the upward and downward rotation of the guide plate 3. When the guide plate 3 rotates upward, it can be used as a limiter at the rear end of the vehicle body 1. When the guide plate 3 rotates downward, it can be used as a guide slope between the vehicle body 1 and the ground, which is convenient for carrying the track to the vehicle body 1. The side limit assembly 6 is used as a limiter at the side end of the vehicle body 1. A pair of side limit assemblies 6, the guide plate 3 and the traction mechanism 4 are circumferentially enclosed on the vehicle body 1, so as to effectively limit and prevent the tracks stacked on the vehicle body 1 from falling.

[0026] Since the rails mostly slide sideways, the side limit assembly 6 is locked with the vehicle body 1 through the locking assembly 7 to improve the limiting effect of the side limit assembly 6 on the rails.

[0027] Please see attached Figure 1 and attached Figure 2 The traction mechanism 4 includes a traction frame 41, a traction rope 42 and a battery 5; the traction frame 41 is installed at the front end of the vehicle body 1, one end of the traction rope 42 is wound around the traction frame 41, and the other end of the traction rope 42 is connected to the guide plate 3, so that the guide plate 3 is rotatably installed at the rear end of the vehicle body 1 through the traction rope 42 via a rotating shaft; the battery 5 is installed at the bottom of the vehicle body 1 and is electrically connected to the traction frame 41, the battery 5 is located between the plurality of tires 2, and the bottom surface of the battery 5 is higher than the bottom surface of the tire 2.

[0028] Preferably, the traction frame 41 may include a control box, a traction motor, a mounting plate and a rope winding shaft, wherein the control box is mounted at the front end of the vehicle body 1, a pair of mounting plates are installed at intervals on the top of the control box, the traction motor is mounted on one of the mounting plates, the rope winding shaft is rotatably mounted between the pair of mounting plates through a rotating bearing, and one end of the rope winding shaft is coaxially fixedly connected to the output shaft of the traction motor. The traction motor is powered by a battery 5.

[0029] One end of the traction rope 42 is fixed on the rope winding shaft. When the traction motor drives the rope winding shaft to rotate in the forward direction, the traction rope 42 is wound on the rope winding shaft, the traction rope 42 shortens and pulls the guide plate 3 to rotate upward to a vertical state. On the contrary, when the traction motor rotates in the reverse direction, the traction rope 42 extends and moves down the guide plate 3, causing the guide plate 3 to rotate backward and downward and form a guiding slope, which is convenient for the rail to be transported to the vehicle body 1.

[0030] Please see attached Figure 3 A pair of latches 61 is provided at the bottom of each group of the side limit assemblies 6, and a pair of latch holes (not shown in the figure) are provided on the side of the vehicle body 1. The pair of latches 61 respectively pass through the pair of latch holes to the bottom of the vehicle body 1; the locking assembly 7 is arranged at the bottom of the vehicle body 1 and is movably connected with the pair of latches 61.

[0031] The plugging of the pair of latches 61 and the pair of latch holes can make the plugging of the side limit assembly 6 on the vehicle body 1 more convenient, which is conducive to ensuring the transportation efficiency after the rail is disassembled. At the same time, the pair of latches 61 are plugged and locked by the locking assembly 7 to ensure the installation stability of the side limit assembly 6. When the rail overturns and hits the side limit assembly 6, the side limit assembly 6 is not easy to fall off or deform and damage.

[0032] Please see attached Figure 3 The side limit assembly 6 includes a mounting rod 62, a positioning sleeve 63 and a load-bearing frame 64; the lower ends of a pair of mounting rods 62 are coaxially fixedly connected to the upper ends of a pair of pins 61, and the pair of mounting rods 62 are respectively inserted into a pair of positioning sleeves 63, and the pair of positioning sleeves 63 are respectively installed on the vehicle body 1 and aligned with a pair of pin holes; the load-bearing frame 64 is installed on the pair of positioning sleeves 63, so that the load-bearing frame 64 forms a fence structure on the side of the vehicle body 1.

[0033] Preferably, the mounting rod 62 and the latch pin 61 are an integral structure, and the positioning sleeve 63 is used to insert the mounting rod 62. After the latch pin 61 is inserted into the latch pin hole, the bottom surface of the positioning sleeve 63 fits against the top surface of the vehicle body 1, thereby increasing the contact area between the side limit assembly 6 and the vehicle body 1, and protecting and strengthening the mounting rod 62, thereby further improving the installation stability of the side limit assembly 6.

[0034] Preferably, the load-bearing frame 64 can be composed of horizontal bars and oblique bars, and the positioning sleeve 63 serves as the vertical bar of the load-bearing frame 64, so that the load-bearing frame 64 has good structural strength, strong bearing capacity, and is not easy to deform or damage.

[0035] Please see attached Figure 4 The two sides of the load-bearing frame 64 are provided with side support plates 65 , and a pair of side support plates 65 are respectively located at the front and rear sides of a pair of positioning sleeves 63 .

[0036] A pair of side support plates 65 serve as vertical rods of the load-bearing frame 64 to further improve the structural strength of the load-bearing frame 64 .

[0037] Please see attached Figure 3 Anti-collision pads 66 are provided on the inner walls of both sides of the load-bearing frame 64 , and the disassembled rails rest against the anti-collision pads 66 .

[0038] Preferably, the anti-collision gasket 66 can be made of rubber material, which has good anti-slip and shock-absorbing effects, and can buffer the impact force of the track on the load-bearing frame 64, thereby ensuring the installation stability of the side limit assembly 6.

[0039] Please see attached Figure 3 and attached Figure 4The locking assembly 7 includes a mounting frame 71, a restraining frame 72, a forward and reverse threaded rod 73 and a limit pin 74; the mounting frame 71 is fixedly mounted on the side bottom surface of the vehicle body 1, and the forward and reverse threaded rod 73 is rotatably mounted on the mounting frame 71 through a plurality of restraining frames 72; one end of a pair of limit pins 74 is respectively threadedly screwed on the two ends of the forward and reverse threaded rod 73, and the other ends of the pair of limit pins 74 are respectively correspondingly inserted into the limit pin holes of the latch 61.

[0040] The forward and reverse threaded rod 73 is installed to the bottom of the vehicle body 1 through the mounting frame 71 and the restraining frame 72. Two sections of external threads with opposite thread directions are formed on the forward and reverse threaded rod 73, which are used to control the limit pin 74 to extend into the limit pin hole inserted into the latch 61, thereby locking the latch 61.

[0041] Please see attached Figure 4 , both sides of the bottom of the mounting frame 71 are installed with limit frames 75, and a through hole is formed in the limit frame 75 for the limit pin 74 to pass through, and a convex strip 77 is formed on the inner wall of the through hole along the axial direction of the limit frame 75, and a groove 78 matching the convex strip 77 is formed on the surface of the limit pin 74 along the axial direction of the limit pin 74, so that the limit pin 74 can coaxially move through the limit frame 75.

[0042] When the forward and reverse threaded rods 73 are rotated, the limit frame 75 is fixed on the mounting frame 71 and cannot rotate, and the limit pin 74 cannot rotate under the limitation of the convex strip 77 and the groove 78. Under the transmission of the thread, the rotation of the forward and reverse threaded rods 73 is converted into a linear motion of the limit pin 74 along the axial direction of the forward and reverse threaded rods 73, so that a pair of limit pins 74 are simultaneously pushed outward and inserted into the limit pin holes of the latch 61 by using two sections of external threads with opposite thread directions, or a pair of limit pins 74 are simultaneously retracted and disengaged from the limit pin holes of the latch 61, thereby ensuring the quick locking and unlocking function of the latch 61.

[0043] Preferably, the convex strips 77 and the concave grooves 78 are arranged in pairs, at least one pair is arranged, and the number of pairs and the arrangement spacing can be adaptively adjusted according to actual use requirements.

[0044] Please see attached Figure 3 A non-slip handle 76 is provided in the middle of the forward and reverse threaded rod 73.

[0045] Preferably, the anti-slip handle 76 can be made of rubber material, which has good grip comfort and anti-slip effect, and is convenient for driving the forward and reverse threaded rods 73 to rotate through the anti-slip handle 76.

[0046] Please see attached Figure 1 To Attachment Figure 4 , the usage method and working principle of the utility model are:

[0047] The vehicle body 1 can be a conventional flatbed truck, the traction mechanism 4 can be used as the front end limit of the flatbed truck, the guide plate 3 can be used as the rear end limit of the flatbed truck, and a pair of side limit assemblies 6 can be used as the side limits of the flatbed truck, thereby ensuring that the tracks stacked on the flatbed truck will not overturn or fall out of the flatbed truck due to external forces during transportation.

[0048] When the traction motor on the traction frame 41 is started and rotates in the reverse direction, the traction rope 42 is released, causing the guide plate 3 to rotate toward the rear and lower side of the vehicle body 1, forming a guiding slope, which is convenient for loading the disassembled track onto the vehicle body 1; when the traction motor rotates forward, the traction rope 42 is reeled in, causing the guide plate 3 to rotate upward to a vertical state, so as to prevent the track from sliding backward.

[0049] A pair of side limit assemblies 6 are plugged and locked on both sides of the vehicle body 1. The plugging and locking method of each set of side limit assemblies 6 is as follows:

[0050] A pair of latch pins 61 are vertically passed through the latch pin holes on the side of the vehicle body 1, so that the bottom of the positioning sleeve 63 abuts against the top surface of the vehicle body 1, and the anti-slip handle 76 is held and the positive and negative threaded rod 73 is rotated. While the positive and negative threaded rod 73 is rotated, a pair of limit pins 74 are coaxially moved away from the positive and negative threaded rod 73 through thread transmission, and a pair of limit pins 74 are laterally inserted into the limit pin holes reserved on the latch pin 61, and the latch pin 61 is locked on the vehicle body 1, so that the side limit assembly 6 forms a fence structure with stable installation and high structural strength on the side of the vehicle body 1, which is used to prevent the track from sliding sideways.

[0051] When unloading the track, the above steps are performed in reverse, the side limit assembly 6 is removed from the vehicle body 1, and the guide plate 3 is flipped backward and downward to an inclined state, which will not be repeated here.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
