Description
Technical field
The utility model relates to the haulage equipment of building materials, is specially a kind of hand barrow for building.
Background technology
When transport building materials, the situation of descending often can be run into.Workman is when push the hand barrow descending that material is housed, and hand barrow can be subject to the component along oblique prone gravity, thus makes spontaneous the moving down of hand barrow.Now, workman often needs hand barrow to haul to move down.When the weight ratio of material is larger time, workman often utilizes the friction on the strut bar on hand barrow and ground too fast to prevent hand barrow from moving.Thus, the friction on strut bar and ground and make strut bar be subject to larger moment of flexure, thus usually make strut bar occur bending and deformation or come off.And workman uses also very inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of hand barrow for building, needs the hand barrow of pulling backward firmly, thus make workman use inconvenient problem to solve workman when workman in prior art pushes away material descending with hand barrow.
To achieve these goals, the one that the utility model provides hand barrow for building, comprises hopper, and hopper is provided with handle and strut bar, and the bottom of hopper is provided with adapter shaft, and adapter shaft is provided with wheel, and wheel and adapter shaft are rotationally connected; The below of described strut bar is provided with pulley, Connection Block is provided with between pulley and strut bar, Connection Block is connected with pulley rotation, Connection Block and strut bar sliding block joint, strut bar offsets through Connection Block and pulley, and strut bar is arranged with spring, and one end of spring is fixedly connected with strut bar, the other end and the Connection Block of spring offset, the lower end of strut bar be provided with antifriction rubber block.
Hopper is set, for holding material.Hopper arranges handle, by hand-held lever operated when workman moves hopper.Hopper arranges strut bar, and in time not needing mobile hopper, strut bar is for supporting hopper not run-off the straight.Arrange adapter shaft in the bottom of hopper, adapter shaft is provided with wheel, and wheel and adapter shaft are rotationally connected, and wheel is used for support and connection axle and moves, and adapter shaft moves for supporting hopper.Be provided with pulley in the below of strut bar, be provided with Connection Block between pulley and strut bar, Connection Block is connected with pulley rotation, and during use, strut bar, by pulley and Connection Block and earth surface, avoids strut bar directly and earth surface and produce friction.Connection Block and strut bar sliding block joint, strut bar offsets through Connection Block and pulley, realizes by the position controlling strut bar and pulley the rotation controlling pulley.Strut bar is arranged with spring, and one end of spring is fixedly connected with strut bar, and the other end and the Connection Block of spring offset, during use, workman, by pressing down strut bar, making strut bar and pulley offset, thus making can not relatively rotate between pulley and Connection Block.The lower end of strut bar is provided with antifriction rubber block, realizes by the pressure controlled between antifriction rubber block and pulley the brake applications controlling pulley.
Principle of work: time workman pushes hand barrow descending, workman regulates the distance between strut bar and pulley by the height of regulating handle, thus antifriction rubber block on adjustment strut bar and the friction force between pulley, and then realize the velocity of rotation controlling pulley.When the component of the hopper gravity downward along slope is larger, workman by increasing the friction force between antifriction rubber block and pulley, thus makes the velocity of rotation of pulley reduce, and produces larger friction force, make the moving velocity of hand barrow slower between pulley and ground.
Compared with prior art, the advantage of this programme is: workman, when promotion hand barrow descending, just can reach the object of the moving velocity controlling hand barrow by the height of control handle, thus facilitates workman's use.
Further, described Connection Block and strut bar are rotationally connected.During use, pulley can rotate around strut bar, thus makes the convenient turning of hand barrow.
Further, the surface of described pulley is provided with anti-skidding indenture.Increase the friction coefficient of pulley, and then increase pulley and ground, friction force between pulley and antifriction rubber block.
Further, described antifriction rubber block and strut bar are bolted.Antifriction rubber block belongs to consumable accessory, changes after using a period of time with regard to needs, by using bolt to connect, facilitates the replacement operation of antifriction rubber block.
Further, described Connection Block is provided with pedal, pedal and Connection Block hinged, pedal is provided with brake plate.By push down on the pedal, brake plate and pulley are offseted, thus make can not relatively rotate between pulley and Connection Block, prevent hand barrow automatic moving.
Further, be provided with the pipe link of inclination between described strut bar and hopper, pipe link is vertical with adapter shaft.During hand barrow motion, when pulley and earth surface, strut bar mainly bears the diametral load parallel with sense of motion, by arranging the pipe link of inclination between strut bar and hopper, enhances the stability of strut bar.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the utility model hand barrow for building.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
In figure: hopper 1, handle 2, adapter shaft 3, wheel 4, pipe link 5, strut bar 6, spring 7, Connection Block 8, antifriction rubber block 9, pulley 10, pedal 11.
Hand barrow for building as shown in Figure 1, comprises hopper 1, and the right side at hopper 1 top is welded with handle 2.The bottom of hopper 1 is provided with adapter shaft 3, and adapter shaft 3 is provided with wheel 4, and wheel 4 and adapter shaft 3 are rotationally connected.The right side of hopper 1 bottom is provided with vertical strut bar 6, is provided with the pipe link 5 of inclination between the bottom of strut bar 6 and hopper 1, and one end of pipe link 5 is welded with strut bar 6, and the other end of pipe link 5 and the bottom welding of hopper 1, pipe link 5 is vertical with adapter shaft 3.The bottom of strut bar 6 is provided with block, and the downside of block is provided with spring 7, and spring 7 is set on strut bar 6.The lower end of spring 7 is provided with Connection Block 8, and the position of the side that keeps left of the upper end of Connection Block 8 is provided with sleeve pipe, and casing pipe sleeve is located on strut bar 6.The lower end of strut bar 6 is through Connection Block 8.The bottom of Connection Block 8 is provided with pulley 10, and pulley 10 and Connection Block 8 are rotationally connected.The right side of Connection Block 8 is hinged with pedal 11, and the downside of pedal 11 is provided with the brake plate of elastomeric material.The periphery of pulley 10 is provided with anti-skidding indenture.Be provided with antifriction rubber block 9 between pulley 10 and strut bar 6, antifriction rubber block 9 is bolted on the lower end of strut bar 6.Antifriction rubber block 9 is offseted by the slip of strut bar 6 and pulley 10.
During use, time workman pushes hand barrow descending, workman regulates the distance between strut bar 6 and pulley 10 by the height of regulating handle 2, thus regulates the friction force between antifriction rubber block 9 on strut bar 6 and pulley 10, and then realizes the velocity of rotation controlling pulley 10.When the component of hopper 1 gravity downward along slope is larger, workman is by increasing the friction force between antifriction rubber block 9 and pulley 10, thus the velocity of rotation of pulley 10 is reduced, larger friction force is produced between pulley 10 and ground, make the moving velocity of hand barrow comparatively slow, thus facilitate workman's use.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
