DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] Embodiment 1: A subway track material transfer trolley comprises a fixed base 1 and a square groove 2, wherein the square groove 2 is provided on one side of the upper surface of the fixed base 1, a buffer mechanism is provided on the bottom surface of the fixed base 1, and a unloading mechanism is provided on the upper surface of the fixed base 1;

[0027] The buffer mechanism includes a damping rod 312, a base plate 313, a fixed block 316, a rotating shaft groove 317, a rotating shaft 318, an oblique connecting plate 319, a slide groove 320, a slider 321 and a compression spring 322. The damping rod 312 is fixedly connected to the bottom surface of the fixed base 1, the base plate 313 is fixedly connected to the bottom end of the damping rod 312, the fixed block 316 is fixedly installed on the bottom surface of the fixed base 1, the rotating shaft groove 317 is opened on the side of the fixed block 316, the rotating shaft 318 is connected to the inner wall of the rotating shaft groove 317, the oblique connecting plate 319 is fixedly installed on the outer surface of the rotating shaft 318, the slide groove 320 is opened on the upper surface of the base plate 313, the slider 321 is installed on the inner bottom surface of the slide groove 320, and the compression spring 322 is fixedly connected to the inner wall of the slide groove 320.

[0028] A square plate 314 is fixedly installed on the bottom surface of the bottom plate 313, and a moving wheel 315 is connected to the bottom surface of the square plate 314. The square plate 314 is symmetrically distributed at the four corners of the bottom surface of the bottom plate 313, and the slide groove 320 is symmetrically distributed on both sides of the upper surface of the bottom plate 313. One end surface of the slider 321 is fixedly connected to the lower end of the oblique connecting plate 319, and the other end surface of the slider 321 is fixedly connected to one end of the compression spring 322. The slider 321 is symmetrically distributed on both sides of the bottom surface of the slide groove 320, and the fixed blocks 316 are symmetrically distributed on both sides of the bottom surface of the fixed base 1. The shaft grooves 317 are symmetrically distributed on both sides of the fixed blocks 316, and the damping rods 312 are symmetrically distributed at the four corners of the bottom surface of the fixed base 1. By setting the buffer mechanism, it is convenient to use a trolley to transport materials in the subway track to buffer the vibration caused by road bumps, so that the movement is smooth to avoid damage caused by material falling.

[0029] The fixed base 1 is connected to the base plate 313 through the damping rod 312. When the push rod 301 is pushed to cooperate with the moving wheel 315 on the bottom surface of the base plate 313 to move, the road bumps and vibrations are generated. At this time, the damping rod 312 performs a reciprocating motion in the opposite direction of the vibration transmission to buffer the vibration. At the same time, when the damping rod 312 moves up and down, the oblique connecting plate 319 drives the rotating shaft 318 to rotate. One end of the oblique connecting plate 319 pushes the sliding block 321 to slide on the bottom surface of the slide groove 320 to squeeze the compression spring 322 fixedly connected to the inner wall of the slide groove 320, so that the compression spring 322 generates a restoring elastic force to buffer the vibration, achieve smooth transportation and avoid material falling.

[0030] Embodiment 2: Based on embodiment 1, the unloading mechanism includes a hydraulic cylinder 305, a lifting column 306, a placement plate 307, a horizontal column 308, a vertical plate 309, a rotating shaft 310 and a connecting block 311. The hydraulic cylinder 305 is fixedly installed on the inner bottom surface of the square groove 2, the lifting column 306 is installed on the output end of the hydraulic cylinder 305, the placement plate 307 is fixedly installed on the upper surface of the lifting column 306, the horizontal column 308 is fixedly installed on one side of the upper surface of the fixed base 1, the vertical plate 309 is fixedly installed on the side of the horizontal column 308, the rotating shaft 310 is installed on the upper part of the side of the vertical plate 309, and the connecting block 311 is fixedly installed on the bottom surface of the placement plate 307.

[0031] The hydraulic cylinders 305 are symmetrically distributed on both sides of the bottom surface of the square groove 2, and the connecting blocks 311 are symmetrically distributed on both sides of the bottom surface of the placement plate 307. There are holes passing through the sides of the connecting blocks 311, and the outer surface of the rotating shaft 310 contacts the inner wall of the hole. A concave baffle plate 3 is fixedly installed on the upper surface of the fixed base 1, and push rods 301 are fixedly installed on both sides of the upper part of one end surface of the concave baffle plate 3. A slot 302 is opened on one side of the upper surface of the concave baffle plate 3, and a plug rod 303 is inserted inside the slot 302. A connecting plate 304 is fixedly installed on the surface of one end of the plug rod 303, and one end surface of the connecting plate 304 contacts the side surface of the placement plate 307. By setting up the unloading mechanism, after the material is transported to the specified position, the hydraulic cylinder 305 can lift the lifting column 306 to drive one side of the placement plate 307 to rise, so that the transported material can slide to one side for unloading, thereby improving work efficiency.

[0032] After the material is placed on the placement plate 307 for storage, the connecting plate 304 and the insertion rod 303 are placed on the surface of one end of the concave baffle 3. After the insertion rod 303 is inserted into the slot 302, the connecting plate 304 shields and protects the material. After the trolley is transported to the designated position, the insertion rod 303 and the connecting plate 304 are pulled out for unloading. The hydraulic cylinder 305 lifts the lifting column 306 to drive the placement plate 307 to rise. The connecting block 311 fixedly installed on the bottom surface of the other end of the placement plate 307 rotates on the outer surface of the rotating shaft 310. After the placement plate 307 forms an angle with the ground level, the material above the placement plate 307 naturally slides down to complete the unloading.
