Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1, the embodiment provides a concrete hand truck, which comprises a flat plate 1, a material frame 3, a first pulley 21, a second pulley 23, a lever 25, a roller 11, a slide rail 24 and a slide block 26. The flat plate 1 is horizontally arranged, and a plurality of rollers 11 are fixed at the bottom of the flat plate 1. The right-hand member of dull and stereotyped 1 upper surface is fixed with first pulley 21, and the bottom of material frame 3 rotates through first pulley 21 and dull and stereotyped 1 to be connected, and dull and stereotyped 1 upper surface is fixed with support column 22, and the bottom of material frame 3 supports on support column 22, and the slope of the right side wall of material frame 3 sets up and extends to the upper right side of dull and stereotyped 1, and the upper end of the left side wall of material frame 3 is fixed with handle 31. The lever 25 is arranged between the material frame 3 and the flat plate 1, the slide rail 24 is fixed at the bottom of the material frame 3, the slide block 26 is movably connected with the slide rail 24, the right end of the lever 25 is movably connected with the slide block 26, the second pulley 23 is fixed at the left end of the upper surface of the flat plate 1, the lever 25 is rotatably connected with the flat plate 1 through the second pulley 23, the left end of the lever 25 extends to the left side of the flat plate 1, and the left end of the lever 25 is fixed with the pedal 27.

When the handcart is used, concrete is stacked on the material frame 3 of the handcart, and the handcart can be pushed randomly. The trolley can be conveniently moved to a required place under the action of the rollers 11. After moving to the place where the concrete is needed, the unloading can be carried out. When unloading, the user holds the handle 31 to push the material frame 3 upward, and then steps on the pedal 27. When the pedal 27 is stepped on by foot, a downward force is applied to the pedal 27, the pedal 27 drives the left end of the lever 25 to move downward, and the right end of the lever 25 is lifted up under the action of the second pulley 23. The right end of the lever 25 is connected with the bottom of the material frame 3 in a sliding mode through the sliding block 26, so that the material frame 3 is jacked up in the process that the right end of the lever 25 rises, the material frame 3 can be easily turned over around the first pulley 21 under the lifting force of the handle 31 in combination with the lifting force brought by the lever 25, concrete in the material frame 3 is poured out, and discharging is achieved. The staff makes the unloading become more convenient through the cooperation of hand and foot, has alleviateed the burden that the staff unloaded, has improved the efficiency of unloading.

In an embodiment of the utility model, the concrete handcart further includes a supporting rod 41, the supporting rod 41 is vertically arranged, the upper end of the supporting rod 41 is fixed on the right side wall of the material frame 3, the lower end of the supporting rod 41 is fixed with a pressure spring 42, and the lower end of the pressure spring 42 is fixed with a barbed nail 43. When the material frame 3 is lifted and turned over through the first pulley 21, the distance between the right end of the material frame 3 and the ground is closer and closer, and at the moment, the barbed nails 43 on the supporting rods 41 are inserted into the ground to provide fixing acting force so as to prevent the trolley from sliding in the unloading process.

In an embodiment of the present invention, the handle 31 is sleeved with an anti-slip rubber strip 32. The anti-slip rubber strip 32 can increase the friction between the hand of the user and the handle 31 to prevent the occurrence of slip.

In an embodiment of the present invention, a lighting lamp 5 is fixed on the right side wall of the material frame 3. In the not good construction place of illumination two, open light 5 and illuminate the direction that gos forward, facilitate for the constructor.

In one embodiment of the present invention, a baffle 33 is fixed on the upper end of the left side wall of the material frame 3. If scram or sharp start all can make the concrete in the material frame 3 take place to rock at the in-process of shallow, baffle 33 can prevent that the concrete from rocking to dash staff's on one's body.

In an embodiment of the present invention, a wheel locking device 13 is disposed on the roller 11. The wheel locking device 13 in this embodiment is a wheel locking device 13 commonly used in the roller 11, and presses the roller 11 tightly to lock the roller 11 by pressing the wheel locking device down, so that the roller 11 can be locked without using a cart, and the roller 11 is prevented from sliding.

In an embodiment of the present invention, the roller 11 is sleeved with a rubber tire 12. The rubber tire 12 has a strong compression buffering capacity, and can reduce the influence of uneven road surface on the trolley when sliding.
