Abstract
The invention provides an automobile braking trolley for a construction site. The automobile braking trolley comprises an automatic braking mechanism composed of circular gears, levers and a push rod. The circular gears are fixedly arranged on an axle of the trolley. One ends of the levers are each provided with a straight tooth. The middles of the levers are hinged to the bottom of the trolley and the straight tooth parts are located above the circular gears. The other ends of the levers are hinged to one end of the push rod. Supporting legs of the trolley are provided with push rod limiting sliding ways. The push rod is placed in the push rod limiting sliding ways. The length of the push rod is equal to or larger than the length of the supporting legs of the trolley. According to the automobile braking trolley, a common trolley for the construction site is improved, the simple automatic braking mechanism is additionally arranged, the braking effect is achieved through the weight of the trolley and the weight of a loaded object, and the requirements for use convenience and safety of tools in the construction process can be met.
Description
Technical field
What the present invention relates to is a kind of hand barrow, specifically a kind of can the building site hand barrow of autobrake.
Background technology
Building site hand barrow is a kind of People-Powered Vehicle that construction site is common both at home and abroad at present, is often used for carrying the building materialss such as fragment of brick, sandstone, cement concrete.Owing to being manpower operation; the senses of discomfort such as tired may be there is in workman in transportation; the rugged place on road surface is caused to occur parking improper maloperation of Denging; and in Practical Project; workyard usually neither be very smooth; often have fluctuating section in transit; in order to avoid the potential safety hazard that may occur because of workman's maloperation; the automatic brake arrangement that hand barrow installs additional is very necessary; ensure that hand barrow in use stable is parked; meanwhile, guarantee to transport the personal safety in weight process.
Conventional brake equipment normally needs to be braked brake equipment operation by user during braking, seldom can reach the effect of autobrake.Some automatic brake arrangements based on security consideration often design complexity, need other auxiliary power unit supports, and in building construction process, environmental conditions are poor, and the auxiliary construction instrument that workman uses often requires simply light, sturdy and durable.
Summary of the invention
The object of the present invention is to provide a kind ofly do not need to add engine installation, do not need that manual operation, structure are simple, cost is low can the building site hand barrow of autobrake.
The object of the present invention is achieved like this:
Comprise the self-sustaining gear be made up of Knucle-gear, lever and push rod, described Knucle-gear is fixedly mounted on the wheel shaft of hand barrow, one end of described lever is with straight-tooth, the middle part of lever is hinged on the bottom of hand barrow and straight-tooth part is positioned at the top of Knucle-gear, the other end of lever and one end of push rod hinged, the supporting leg of hand barrow is arranged the spacing slideway of push rod, push rod is placed in the spacing slideway of push rod, and the length of push rod is equal to or greater than the length of hand barrow supporting leg.
The present invention can also comprise:
1, comprise two cover self-sustaining gears, two cover self-sustaining gears lay respectively at the both sides bottom hand barrow, and two supporting legs of hand barrow arrange the spacing slideway of push rod respectively.
2, the structure of the spacing slideway of push rod is hand barrow supporting leg is sleeve-shaped, and the upper end of sleeve-shaped hand barrow supporting leg has groove, and push rod is placed in sleeve-shaped hand barrow supporting leg, and lever is arranged in the groove of hand barrow supporting leg upper end.
3, sleeve-shaped hand barrow supporting leg has position-limited trough, with locating dowel pin on push rod, locating dowel pin is arranged in described position-limited trough.
4, the spacing slideway of push rod comprises at least two spacing rings be fixed on hand barrow supporting leg.
5, on push rod with locating dowel pin, locating dowel pin is between two spacing rings.
6, the lower end of push rod is with supporting seat.
The present invention improves on the basis of common building site hand barrow, has installed simple automatic brake arrangement additional, utilizes the own gravity of hand barrow and loads to reach braking effect, can meet the easy to use and security requirement of instrument in work progress.Consider save construction cost, the operating time of not adding in extra transport, the automatic brake arrangement that installs additional of the present invention should be lightweight and be easy to dismounting, maintenance, meanwhile, when brake equipment lost efficacy, do not affect and transport use normally.
The invention has the advantages that and do not need to add other engine installations and manual operation, rely on the gravity of car body and loads just can realize autobrake, and due to primary member great majority employing pin connection and welding, facilitate the autonomous dismounting and change of workman, effectively can save financial cost, simultaneously, when brake equipment lost efficacy, can dismantle brake equipment, the transport meeting normal hand barrow uses, and does not affect normal construction schedule requirement.

Detailed description of the invention
Below in conjunction with Fig. 1-4 citing, a specific embodiment of the present invention is described in more detail.
Can the building site hand barrow of autobrake, comprise car body and brake equipment.Car body is common building site hand barrow, and bottom is provided with wheel and supporting leg, and end is provided with two handles, and handle end bends.Brake equipment mainly comprises set of gears group and rod gear.Rod gear mainly adds in a steel hollow in common hand barrow supporting leg pipe manages, and slot in pipe upper end outside, so that interior pipe is connected with lever.Interior pipe is directly inserted in bearing pipe, in order to avoid interior pipe skids off from bearing pipe, welds bayonet lock on inner pipe, and slots in the middle part of outer tube, limits the movement of bayonet lock thus the slip of the interior pipe of restriction.Meanwhile, the boring of end fluting, is connected with lever one end by pin, lever energy is rotated around pin on inner pipe.Gear cluster is made up of one group of Knucle-gear and straight-tooth, and Knucle-gear is welded on wheel shaft, and straight-tooth is welded on the other end of lever.In vehicle bottom welded connections, use pin truck dead lever, lever energy is freely rotated around pin.
When dolly is in parked state, due to Gravitative Loads, two bearings contact to earth, and interior pipe 3 can be headed in bearing outer tube 2 completely, interior pipe 3 upper end moves up, drive lever 4 one end to lift, meanwhile, lever 4 other end having welded straight-tooth 6 then declines, straight-tooth 6 blocks in Knucle-gear 5, thus limit the rotation of wheel shaft 7, tire 8 locking, and then the movement of restriction dolly.And along with the increase of dolly weight, interior pipe 3 is increased by the power heading into bearing outer tube 2, more increases the occlusion between gear cluster, and the locking power of dolly tire 8 is larger.Owing to being by deadweight to provide braking, therefore parking at any time and can play autobrake, play the effect of security insurance, and do not need to carry out operation bidirectional.
When lifting handle 1 and promoting dolly, because two bearings leave ground, the interior pipe 3 in bearing to glide out outer tube 2 in the effect of gravity own, due to the bayonet lock that middle part adds, what limit interior pipe 3 skids off length, and what make interior pipe 3 skids off the normal movement not affecting dolly.Along with interior pipe 3 skids off a part, interior pipe 3 upper end declines, and drive lever 4 to decline near one end of handle, thus the other end straight-tooth 6 of lever 4 lifts, and departs from Knucle-gear 5, dolly wheel shaft 7 and tire 8 recover turning power again.
