[0017] Firstly, this invention uses several support components to place the transport frame on a steep mountain slope. Then, two walking components work together to move the railcar body on two tracks. Construction materials are placed on the top of the support plate. A limiting mechanism clamps and limits the construction materials on the support plate.

[0019] Thirdly, this invention uses a drive motor to drive a drive gear to rotate. The drive gear uses two moving racks to move two moving frames closer or further apart, thereby adjusting the distance between the two limiting frames. This allows the two limiting components to clamp and limit construction materials of different lengths.

[0020] Fourthly, this invention uses a rotating handle to drive a screw to rotate within a screw sleeve for lifting and lowering. The screw then drives a support plate to lift and lower, thus facilitating the placement of the transport frame on steep mountain slopes. Attached Figure Description

Detailed Implementation

[0037] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides, through improvements, a construction material transport device for steep mountain slopes, such as... Figures 1-13As shown, the system includes a transport frame 1, with several support components 2 at its bottom. Two rails 11 are symmetrically arranged at the top of the transport frame 1, and railcar bodies 12 are mounted on the two rails 11. A support plate 3 is slidably installed inside the railcar body 12. Two buffer components 4 are symmetrically arranged between the interior of the railcar body 12 and the bottom of the support plate 3. A limiting mechanism 5 is provided at the top of the railcar body 12. Two anti-detachment racks 6 are symmetrically arranged on the outer wall of the transport frame 1, and two anti-detachment components 7 are symmetrically arranged on the outer wall of the railcar body 12. The bottom ends of the two anti-detachment components 7 respectively engage with the two anti-detachment racks 6. Two traveling components 8 are symmetrically arranged at the top of the transport frame 1. One end of each walking component 8 is connected to the bottom outer wall of the railcar body 12. Several support components 2 are used to place the transport frame 1 on a steep mountain slope. Then, the two walking components 8 work together to drive the railcar body 12 to move on two tracks 11. Construction materials are placed on the top of the bearing plate 3. The limiting mechanism 5 clamps and limits the construction materials on the bearing plate 3. At the same time, two anti-detachment components 7 perform anti-detachment operations on the railcar body 12 during its movement to prevent the railcar body 12 from falling off the track 11 and causing damage to the construction materials. Two buffer components 4 provide shock absorption for the bearing plate 3 to prevent vibration damage to the construction materials and reduce transportation costs.

[0039] Specifically, the anti-derailment assembly 7 includes a belt 71 and two anti-derailment components 72. The two anti-derailment components 72 are symmetrically arranged on the outer wall of the railcar body 12, and the bottom ends of the two anti-derailment components 72 mesh with corresponding anti-derailment racks 6. The anti-derailment component 72 includes a mounting frame 73, a rotating shaft 74, an anti-derailment gear 75, a pulley 76, and a locking component 77. The mounting frame 73 is arranged on the outer wall of the railcar body 12. The rotating shaft 74 is rotatably mounted on the bottom end of the mounting frame 73. The anti-derailment gear 75 is mounted on the bottom end of the rotating shaft 74 and meshes with the corresponding anti-derailment rack 6. The pulley 76 is mounted on the top end of the rotating shaft 74 and has several insertion holes 78. The locking component 77 is located at the top of the mounting bracket 73, and the bottom end of the locking component 77 is inserted into the corresponding insertion hole 78. The belt 71 is sleeved on the outside of the pulleys 76 in the two anti-detachment components 72. The anti-detachment gear 75 is driven to rotate by the anti-detachment rack 6. The anti-detachment gear 75 drives the pulleys 76 in the two anti-detachment components 72 to rotate synchronously by the belt 71. When it is necessary to prevent the railcar body 12 from detaching, the locking component 77 works to drive its bottom end to be inserted into the corresponding insertion hole 78. At this time, the pulleys 76 and the anti-detachment gear 75 cannot rotate, thereby realizing the anti-detachment operation of the railcar body 12 and preventing the railcar body 12 from falling off the rail 11 and causing damage to the construction materials.

[0040] Specifically, the locking component 77 includes a hydraulic push rod 771, a locking block 772, and a pin 773. The hydraulic push rod 771 is vertically mounted on the top of the mounting bracket 73. The locking block 772 is mounted on the output end of the hydraulic push rod 771. The pin 773 is mounted on the bottom of the locking block 772, and the bottom end of the pin 773 is inserted into the corresponding insertion hole 78. The operation of the hydraulic push rod 771 drives the locking block 772 and the pin 773 to move downward. The bottom end of the pin 773 moves downward until it is inserted into the corresponding insertion hole 78, and the pin 773 prevents the pulley 76 from rotating.

[0041] Specifically, the buffer assembly 4 includes a first slide rail 41, a second slide rail 42, and two buffer components 43. The first slide rail 41 is horizontally disposed at the bottom of the inner side of the railcar body 12, and the second slide rail 42 is horizontally disposed at the bottom of the support plate 3.

The top of the first slider 44 is provided with a first hinge seat 441, and the bottom of the second slider 45 is provided with a second hinge seat 451. The bottom end of the sleeve 46 is hinged to the first hinge seat 451. Inside 41, buffer block 48 is hinged in the second hinge seat 451, buffer rod 47 is slidably installed in sleeve 46, and the top of buffer rod 47 is connected to the bottom of buffer block 48. Spring 49 is sleeved on the outside of buffer rod 47, and the two ends of spring 49 are respectively connected to sleeve 46 and buffer block 48. During the movement of the railcar body 12, the construction material on the top of the bearing plate 3 will move with the movement, causing the bearing plate 3 to move downward. Then, the bearing plate 3 will drive the first slider 44 and the second slider 45 to move on the first slide rail 41 and the second slide rail 42 for initial buffering and shock absorption. At the same time, buffer block 48, buffer rod 47, spring 49 and sleeve 46 cooperate to perform secondary buffering and shock absorption, preventing construction material vibration damage and reducing transportation costs.

Two limiting components 57 are respectively set on the top of the two limiting frames 54. The drive motor 51 drives the drive gear 52 to rotate. The drive gear 52 uses the two movable racks 56 to drive the two movable frames 55 to move closer or further apart, thereby adjusting the distance between the two limiting frames 54, which facilitates the two limiting components 57 to clamp and limit construction materials of different lengths.

[0043] Specifically, the limiting component 57 includes a U-shaped frame 571, a limiting motor 572, a limiting rod 573, two limiting rails 574, two clamping plates 575, and two pull rods 576.

The first gear 834 drives the take-up shaft 831 and the take-up reel 832 to rotate through the second gear 835. The take-up reel 832 causes the tail end of the steel rope 86 to wind around the surface of the take-up reel 832. The tail end of the steel rope 86 in the other traveling component 8 is released on the surface of the take-up reel 832, thereby enabling the railcar body 12 to move and transport on the two tracks 11.
