Description

Technical Field

[0001] This utility model relates to the field of transportation equipment, and in particular to a prefabricated small component ramp loading and transportation tool. Background Technology

[0002] In slope protection engineering, precast arched frame structures are commonly used for single-level slopes, while multi-level slopes utilize a composite protection system formed by combining arched frames with cast-in-place frame beams. The arched frames are typically constructed by assembling and masonry precast concrete blocks on-site. Traditionally, the transportation of precast blocks relies on two main methods:

[0003] Manual staircase transport: Workers carry precast blocks on their backs along the slope steps or on temporary scaffolding. Manual transport wastes a lot of manpower and is also highly dangerous.

[0004] Slope top chute lowering: A simple chute is set up at the top of the slope, and the precast blocks slide freely down to the working surface. However, the end lacks an effective braking device, which can easily cause block collision damage or personnel injury accidents. Utility Model Content

[0027] Example 1

[0028] See Figures 1 to 4 This utility model provides a prefabricated small component ramp loading and transportation tool, including a winch 1 and a transport vehicle 2 connected to the winch 1, and also includes a generator 3 that provides power to the winch 1;

[0029] The transport vehicle 2 includes a base frame 4, a platform plate 5 is rotatably mounted at one end of the base frame 4, and a roller 6 is mounted at each of the four corners of the lower surface of the base frame 4;

[0030] A locking buckle 7 is fixedly installed in the middle of the base frame 4 near the rotating end of the platform plate 5. The locking buckle 7 is connected to the winch 1 by a steel rope.

[0031] Two fixed rods 8 are fixedly installed at the rotating end of the base frame 4 away from the platform plate 5. A sliding groove 9 is opened on the rod body of each fixed rod 8. A sliding rod 10 is slidably installed in the sliding groove 9. A nut 11 is fixedly installed in the middle of the sliding rod 10.

[0032] A lead screw 12 is also rotatably mounted on the base frame 4. The lead screw 12 is located between two fixed rods 8 and is threadedly connected to the nut 11.

[0033] A connecting rod 13 is rotatably installed at each end of the fixed rod 8, and the movable end of the connecting rod 13 is rotatably connected to the middle of the platform plate 5.

[0034] The transport vehicle 2 is placed on the slope, and the user drives the lead screw 12 to rotate, which drives the nut 11 to move along the axis of the lead screw 12, forcing the sliding rod 10 to slide in the groove 9 of the fixed rod 8;

[0035] When the sliding rod 10 moves, the platform plate 5 is pushed to rise synchronously around the rotating end of the base frame 4 through the connecting rods 13 at both ends of the fixed rod 8. The tilt angle of the platform plate 5 is observed. The platform plate 5 maintains the set tilt angle during the movement of the transport vehicle 2 to ensure the stability of the center of gravity of the precast components during the transport on the slope.

[0036] The generator 3 is started to supply power to the winch 1, and the winch 1 pulls the transport vehicle 2 along the slope via a steel rope.

[0037] The winch 1 includes a frame 14, on which a drum 15 is rotatably mounted. A steel rope is wound on the drum 15. One end of the steel rope is fixed to the drum 15, and the other end is detachably connected to the lock 7 of the transport vehicle 2.

[0038] A drive motor 16 is fixedly installed on the frame 14 on one side of the roller 15. A reduction gearbox 17 is installed between the drive motor 16 and the roller 15. The drive motor 16 drives the roller 15 to rotate through the reduction gearbox 17.

[0039] After the generator 3 starts, the drive motor 16 of the winch 1 reduces the speed and increases the torque through the reduction gearbox 17, driving the drum 15 to rotate at a constant speed.

[0040] As the drum 15 rotates, the steel rope is simultaneously wound up and down, and the transport vehicle 2 is pulled along the slope by the locking buckle 7.

[0041] A mounting hole is made at each of the four corners of the frame 14, and a steel rod 18 is inserted into each mounting hole.

[0042] Position the frame 14 of the winch 1 in the working area at the top of the slope, align the four mounting holes with the preset anchor points, insert the steel rod 18 vertically into each mounting hole, and drive the steel rod 18 into the soil by hammering until the top of the steel rod 18 is flush with the surface of the frame 14.

[0043] After the transport vehicle 2 is loaded with prefabricated components, the winch 1 is started. During the steel rope traction process, the friction between the steel rod 18 and the soil resists the overturning torque of the winch 1 when it is working.

[0044] After transportation is completed, the steel rod 18 can be pulled out, and the surface dirt can be cleaned and reused.

[0045] A handwheel 19 is fixedly installed at one end of the lead screw 12.

[0046] A level bubble is set on platform 5.

[0047] The bubble level provides an immediate visual indication of the tilt status of the platform 5.

[0048] When using this utility model, the transport vehicle 2 is placed on a slope, and the user drives the lead screw 12 to rotate, which drives the nut 11 to move along the axial direction of the lead screw 12, forcing the sliding rod 10 to slide in the groove 9 of the fixed rod 8.

[0049] When the sliding rod 10 moves, the platform plate 5 is pushed to rise synchronously around the rotating end of the base frame 4 through the connecting rods 13 at both ends of the fixed rod 8. The tilt angle of the platform plate 5 is observed. The platform plate 5 maintains the set tilt angle during the movement of the transport vehicle 2 to ensure the stability of the center of gravity of the precast components during the transport on the slope.

[0050] The generator 3 is started to supply power to the winch 1, and the winch 1 pulls the transport vehicle 2 along the slope via a steel rope.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
