[0041] 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.

[0042] Embodiment 1

[0043] See also Figure 1-4 A concrete precast block transport device includes a trolley 1, on which a loading and unloading assembly 2 is provided, and the loading and unloading assembly 2 includes: an inclined plate 21, which is arranged on the left side of the trolley 1; a bracket 22, which is arranged on the top of the trolley 1; a placement frame 23, one end of which is hinged to the top of the bracket 22; an electric push rod 24, the bottom of which is hinged in a through groove inside the trolley 1, and the top of the electric push rod 24 is hinged to the bottom surface of the placement frame 23; a frame 25, which is arranged on the top of the right side of the placement frame 23; and a pulling mechanism 26, which is arranged on the frame 25. The pulling mechanism 26 includes: a motor 261, which is arranged on the outer wall of the frame 25, and the output shaft of the motor 261 penetrates and extends into the frame 25; a rotating shaft 262, which is fixedly connected to the output shaft of the motor 261, and the rotating shaft 262 is rotatably connected to the frame 25; a rope 263, which is symmetrically sleeved on the outside of the rotating shaft 262, and one end of the rope 263 extends to the outside of the frame 25; a mat 264, which is fixedly connected to one end of the rope 263 extending to the outside of the frame 25. The pulling mechanism 26 also includes an anti-slip mat 265 arranged on the inner wall of the mat 264.

[0044] During use, the device is moved to the vicinity of the concrete precast block by using the trolley 1, and the concrete precast block is quickly loaded and unloaded by using the loading and unloading assembly 2: the staff pries one side of the precast block so that one side of the precast block is placed on the left edge of the inclined plate 21, and then the electric push rod 24 is started. When the electric push rod 24 is extended, the placement frame 23 is pushed upward, and the placement frame 23 rotates along the bracket 22 until the placement frame 23 and the inclined plate 21 have the same inclination angle. At this time, the pulling mechanism 26 is used to release the rope 263 from the inside of the frame 25: the motor 261 is started, and the motor 261 drives the rotating shaft 262 to rotate. When the rotating shaft 262 rotates, the rope 263 wrapped around it is gradually released. The staff puts the extended rope 263 on the outside of the concrete precast block, and the pad 264 contacts the left side wall of the precast block. Then the motor 261 is controlled to rotate in the opposite direction. After the motor 261 drives the rotating shaft 262 to rotate in the opposite direction, the rope 263 is released. 63 is retracted and wound, and the rope 263 and the pad 264 are retracted to drive the concrete precast block upward. After the precast block slides into the placement frame 23 through the inclined plate 21, the electric push rod 24 is retracted, and the electric push rod 24 drives the placement frame 23 to rotate back to a horizontal state. At this time, the rope 263 and the pad 264 fix the concrete precast block, and the trolley 1 can be pushed to transport the precast block. When the concrete precast block needs to be unloaded, the electric push rod 24 is controlled to rotate the placement frame 23 to an angle with the inclined plate 21, and the motor 261 is controlled to rotate slowly, and the shaft 262 releases the rope 263. After the rope 263 extends out of the frame 25, the concrete precast block slides downward from the placement frame 23, and the rope 263 is controlled to be slowly released. In order to control the speed at which the precast block slides down and avoid damage caused by excessive sliding speed, the concrete precast block slides to the ground through the inclined plate 21, thereby realizing convenient loading and unloading of the concrete precast block. The anti-skid pad 265 on the inner wall of the mat 264 increases the friction when in contact with the prefabricated concrete block, thereby improving the stability of the prefabricated block when being loaded and unloaded by the rope 263.

[0045] Embodiment 2

[0046] On the basis of the first embodiment, an auxiliary function is added.

[0047] See also Figure 1-4The top of the inclined plate 21 and the bottom surface of the placing frame 23 are both rotatably connected with rollers 28, and the rollers 28 are symmetrically arranged in multiple groups. The frame 25 and the rotating shaft 262 are provided with an anti-entanglement mechanism 27, and the anti-entanglement mechanism 27 includes: a gear 1 271, which is sleeved on the outside of the rotating shaft 262; a reciprocating screw rod 272, which is symmetrically and rotatably connected to the inner wall of the frame 25, and the two reciprocating screw rods 272 are fixedly connected; a gear 273, which is sleeved on the outside of the connection of the reciprocating screw rod 272, and the gear 273 is meshed with the gear 1 271; a threaded block 274, which is symmetrically and threadedly connected to the reciprocating screw rod 272; a ring body 275, which is arranged on the top of the threaded block 274, and the rope 263 passes through the middle of the ring body 275; a slider 276, which is arranged on the left side wall of the ring body 275, and a slide groove for the slider 276 to slide is arranged on the inner wall of the frame 25. The trolley 1 is movably connected with an ash collecting box 3 , and a handle is provided on the front side of the ash collecting box 3 .

[0048] When the concrete precast block slides on the upper surface of the inclined plate 21 and the placement frame 23, it passes through the roller 28, and the roller 28 rotates, which makes it easier for the concrete precast block to slide. The anti-entanglement mechanism 27 prevents the rope 263 from always being entangled at the same position of the rotating shaft 262: when the rotating shaft 262 rotates, the gear 1 271 rotates, and the gear 2 273 meshing with the gear 1 271 drives the two reciprocating screws 272 to rotate synchronously. The threaded block 274 threadedly connected to the reciprocating screw 272 drives the ring body 275 to reciprocate along the reciprocating screw 272. Since the rope 263 passes through the middle of the ring body 275, the ring body 275 guides the rope 263 when it reciprocates. The rope 263 is made to reciprocate and wind along the rotating shaft 262, and the rope 263 is prevented from being stacked and wound due to being wound around the same position of the rotating shaft 262. When the threaded block 274 reciprocates, the slider 276 slides in the slide groove of the left wall of the frame 25 along with the threaded block 274. The slider 276 guides the threaded block 274 to prevent the threaded block 274 from rotating along with the rotation of the reciprocating screw rod 272, thereby losing the guiding effect of the ring body 275 on the rope 263. When the electric push rod 24 pushes the placement frame 23 to tilt, the dust after loading and unloading the concrete prefabricated blocks in the placement frame 23 slides and falls into the ash collecting box 3, which collects the dust to reduce the subsequent cleaning pressure. When the dust in the ash collecting box 3 is full, the staff can pull the handle to take the ash collecting box 3 out of the trolley 1, which is convenient for cleaning the dust in the ash collecting box 3.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
