Embodiment Construction

[0020] Combine below Figure 1-4 A specific embodiment of the present invention will be described in more detail with an example.

[0021] A construction site trolley capable of automatic braking, including a vehicle body and a braking device. The car body is a trolley for common construction sites, with wheels and supporting legs arranged at the bottom, and two handles at the end, the ends of which are bent. The braking device mainly includes a gear set and a lever transmission. The lever transmission device is mainly to add a steel hollow inner tube to the round tube of the ordinary trolley support leg, and slot the upper end of the outer tube so that the inner tube can be connected with the lever. The inner tube is directly inserted into the support round tube. In order to prevent the inner tube from slipping out of the support round tube, a bayonet pin is welded on the inner tube, and a slot is made in the middle of the outer tube to limit the movement of the bayonet pin...

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 [0001] The invention relates to a trolley, in particular to a construction site trolley which can be automatically braked. Background technique [0002] Construction site trolleys are a common means of human transportation in construction sites at home and abroad, and are often used to carry bricks, sandstone, concrete and other building materials. Due to the manual operation, workers may experience fatigue and other discomfort during transportation, resulting in improper parking and other misoperations on rough roads. In actual engineering, the construction site is usually not very smooth, and there are often ups and downs during transportation. In the road section, in order to avoid possible safety hazards due to worker misuse, it is necessary to install an automatic braking device on the trolley to ensure the stable parking of the trolley during use, and at the same time, ensure personal safety during the transportation of heavy objects. [0003] Commonly...
