DETAILED DESCRIPTION

[0037] The embodiments of the utility model will be described by specific examples below, and those skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. Obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0038] For reference Figures 1-8The utility model discloses a transportation device for building construction to reduce the labor intensity of workers, and the specific structure includes frame 1, power -assisted wheel 3 and power supply system 5, wherein, power -assisted wheel 3 is under the power drive of power supply system 5 and rotates automatically, and power -assisted wheel 3 rotation sets up on frame 1 and contacts the ground. The tail end of frame 1 is provided with handrail 6, and frame 1 top installs dump 2, is used for transporting sandstone material and other building materials. Power -assisted wheel 3 is suitable for driving frame 1 to advance, and power -assisted wheel 3 is connected with the circuit of power supply system 5, and power supply system 5 can provide electric energy for power -assisted wheel 3, specifically, when frame 1 meets the situation of uphill, power supply system 5 can provide power for power -assisted wheel 3.

[0039] In the embodiment, power supply system 5 includes battery 51, casing 52, driver 53, singlechip 54, pressure sensor 55 and inclination sensor 56, as Figure 2 And Figure 5 Battery 51 is installed in casing 52, and battery 51 powers driver 53 and singlechip 54. Battery 51 is lithium battery, and power -assisted wheel 3 is mainly rotated through hub motor 31, since singlechip 54 cannot drive motor alone, therefore singlechip 54 drives hub motor 31 to rotate through driver 53, on the other hand, hub motor 31 is a reduction motor, and itself has higher output torque. Pressure sensor 55 and inclination sensor 56 are signal connected with singlechip 54, and pressure sensor 55 and inclination sensor 56 deliver the load weight of frame and the inclination angle value of frame to singlechip 54. Specifically, singlechip 54 controls the output power of hub motor 31 through the mode of pulse width modulation (pwn), and the power of power -assisted wheel 3 is positively related with the weight of dump 2 and the inclination angle of frame 1.

[0040] The internal processing formula of specific singlechip 54 is as follows:

[0041] T=H (sina+kcosa) / R;

[0042] Wherein, T is the output torque of hub motor 31, a is the slope, R is the radius of solid rubber wheel 35, and k is the friction coefficient. From the above, when inclination sensor 56 senses that frame 1 generates inclination angle, hub motor 31 can rotate, thereby driving frame 1 to advance and offsetting the resistance generated by the slope to frame 1.

[0043] In some embodiments, the bottom of the support leg 4 is provided with a power supply system 5, and the top of the support leg 4 is clamped and fixed with the frame 1. Specifically, the support leg 4 comprises a supporting steel pipe 41, a buckle 42 and a bracket 43. The bracket 43 is installed at the end of the supporting steel pipe 41, the supporting steel pipe 41 is in contact with the ground, and a plurality of buckles 42 are arranged on the pipe of the bracket 43 and are clamped and fixed with the bent pipe 11 through the plurality of buckles 42. In this embodiment, the supporting steel pipe 41 and the bent pipe 11 are both whole steel pipes which are bent by heating. The process is relatively simple and easy to mass produce.

[0044] In this embodiment, as Figure 6 , the bracket 43 and the supporting steel pipe 41 are integrally formed. Alternatively, the bracket 43 and the end of the supporting steel pipe 41 can also be rotatably connected, so that the bracket 43 can be folded in the supporting steel pipe 41. In order to disassemble and transport the support leg 4.

[0045] In some embodiments, as Figure 7 , the frame 1 comprises a pair of bent pipes 11 and a pair of wheel shafts 13. The tail end of the pair of bent pipes 11 is provided with a handrail 6, and the two bent pipes 11 are connected through a connecting shaft 12. The connecting shaft 12 is provided with a tipping bucket 2. The pair of wheel shafts 13 are arranged at the head end of the pair of bent pipes 11 and are aligned. The pair of wheel shafts 13 are provided with a motor mounting shaft 14, and the motor mounting shaft 14 is provided with a stator 32. The pair of wheel shafts 13 are rotatably provided with a solid rubber wheel 35, and the solid rubber wheel 35 can freely rotate on the pair of wheel shafts 13.

[0046] In this embodiment, the bent pipe 11 and the supporting steel pipe 41, the buckle 42 and the bracket 43 and the booster wheel 3 can be quickly disassembled and assembled, so that they can be disassembled and transported in large quantities to the construction site, and then assembled for large-scale use.

[0047] In one specific embodiment of the present application, as Figure 3 , the booster wheel 3 comprises a wheel hub motor 31 and a solid rubber wheel 35. The inside of the wheel hub motor 31 is provided with a stator 32. The stator 32 is fixedly arranged at the end of the frame 1, and the stator 32 is a coil which can be connected to a power supply to generate an excitation magnetic field to drive the rotor of the wheel hub motor 31 to rotate in the shell. The shell of the wheel hub motor 31 is provided with a pawl 34. On the other hand, the solid rubber wheel 35 is rotatably arranged at the end of the frame 1, and the solid rubber wheel 35 is provided with a ratchet groove 33 at the shaft center. The stator 32 is adapted to abut the ratchet groove 33 through the pawl 34 and drive the solid rubber wheel 35 to rotate.

[0048] In the embodiment, when the frame 1 is in the flat angle or downhill state, the pawl 34 can slide on the surface of the ratchet wheel groove 33 and does not drive the wheel hub motor 31 to rotate because the wheel hub motor 31 is not started, and when the frame 1 is in the uphill state, the wheel hub motor 31 drives the solid rubber wheel 35 to rotate through the pawl 34, so as to achieve the effect of assisting.

[0049] In some embodiments, as Figure 4 , the skip 2 comprises a connecting shaft 12 and a sleeve 22, the sleeve 22 is sleeved on the connecting shaft 12, the sleeve 22 is integrally formed with the connecting shaft 12, and the connecting shaft 12 is made of glass fiber reinforced plastic, so as to reduce the weight of the whole device.

The components mentioned in the present application are common techniques in the prior art, which should be understood by those skilled in the art. The present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the present application.
