Description

Wheel skating pendulum pile car based on the principle of screw mechanism

technical field

The invention belongs to the field of gear transmission, and relates to a device for a wheel-sliding swing pile vehicle, in particular to a wheel-sliding swing pile vehicle based on the principle of a screw mechanism.

Background technique

With the development of roller skating, more and more people are involved in this sport, including not only young people, but also children and even middle-aged and elderly people. Among all kinds of roller skating sports, flat fancy roller skating has become the most fashionable highlight in roller skating because of its elegant and unrestrained characteristics, and is widely loved by roller skating enthusiasts.

The so-called flat fancy roller skating refers to wearing roller skates to do various continuous sliding without jumping between a fixed number of standard pile distances. The competition is generally divided into 3 rows of piles, with 20 piles in each row, and the pile spacing of each row is 0.5m, 0.8m, and 1.2m respectively, to arrange different pile passing difficulties and techniques. In competitions, practices or performances, we often see roller skating enthusiasts use a ruler to measure a certain distance on the ground and mark it. This method is not only laborious, but also not accurate.

Contents of the invention

The object of the present invention is to solve the above problems and provide a wheel-sliding pile car based on the principle of a screw mechanism. This wheel-sliding pile car has a simple structure, is easy to operate, and is small in size. In order to accurately place the piles, it meets the needs of the majority of roller skating enthusiasts.

The purpose of the present invention is solved by the following technical solutions:

This kind of roller skating pendulum pile vehicle based on the principle of screw mechanism includes a power input part, an intermediate transmission part and a screw mechanism; the power input part includes a rear axle and a wheel and a pulley driving pulley arranged on the rear axle; the intermediate transmission part It includes a pulley driven wheel, a bevel gear pair, a single-stage pulley driving wheel and a single-stage pulley driven wheel; the pulley driven wheel is connected to the pulley driving wheel through a belt, and a bevel gear of the pulley driven wheel and the bevel gear pair is fixed on on one shaft; the other bevel gear of the bevel gear pair is fixed on one shaft with the single-stage pulley driving wheel; the single-stage pulley driving wheel is connected with the single-stage pulley driven wheel through a belt; the The screw mechanism is a screw pair, and the two components of the screw pair are respectively coaxially fixed with the single-stage pulley driving wheel and the single-stage pulley driven wheel; the space between the two members of the screw pair is a place for placing piles.

The distance between the adjacent threads of the above-mentioned screw mechanism is smaller than the gap when two piles are stacked.

The screw threads of the above two screw mechanisms are in opposite directions.

The present invention is a device that can replace people to measure the standard pile distance and can directly place the piles down, and realizes the accurate placement of the piles stably through the internal transmission system with fixed transmission ratio. Since the pile distances in the competition are 0.5m, 0.8m, and 1.2m, the preliminary design is a mechanism that can meet the requirement of placing a pile every 0.8m. Other pile distances can be realized by changing the internal transmission mechanism according to specific needs.

Detailed ways

The present invention is described in further detail below in conjunction with accompanying drawing:

Referring to Fig. 1, this wheel-skating pendulum pile vehicle based on the principle of the screw mechanism includes a power input part, an intermediate transmission part and a screw mechanism 9; Wheel 3; the intermediate transmission part includes a pulley driven wheel 4, a bevel gear pair 5, a single-stage pulley driving wheel 6 and a single-stage pulley driven wheel 7; the pulley driven wheel 4 is connected to the pulley driving wheel 3 by a belt, And the pulley driven wheel (4) and a bevel gear of the bevel gear pair 5 are fixed on one shaft; the other bevel gear of the bevel gear pair 5 and the single-stage pulley driving wheel 6 are fixed on one shaft; The single-stage pulley driving wheel 6 is connected with the single-stage pulley driven wheel 7 through a belt; Moving wheel 7 is coaxially fixed. As shown in Figure 2, the space between the two components of the screw pair is the space for placing the pile 8, the distance between adjacent threads of the screw mechanism 9 is smaller than the gap when the two piles are overlapped, and the screw threads of the two screw mechanisms 9 have opposite directions.

Working process of the present invention is as follows:

Through the non-sliding contact between the wheel 1 and the ground, the rotation of the rear axle 2 drives the driving wheel 3 of the three-stage pulley to rotate, drives the driven wheel 4 of the three-stage pulley to rotate, makes the bevel gear pair 5 rotate, and drives the coaxial single-stage pulley driving wheel 6 rotates so that the single-stage pulley driven wheel 7 rotates, and the two single-stage pulleys 6 and 7 drive the coaxial screw mechanism 9 to rotate. Cooperate, make the bottom pile separate from the stacked pile 8, and fall to the designated position.

In order to meet the requirements of roller skating and accurately control the distance between every two piles, the whole mechanism has a more precise transmission ratio. The following is the relevant data of the transmission ratio: the circumference of the wheel is 800mm, to ensure that the axis 2 rotates once every time it advances 800mm, and the transmission ratio of the sports pair is 1:1, so as to achieve the purpose of laying down a pile every 800mm.

The present invention is a device that can replace people to measure the standard pile distance and can directly place the piles down, and realizes the accurate placement of the piles stably through the internal transmission system with fixed transmission ratio. Since the pile distances in the competition are 0.5m, 0.8m, and 1.2m, the preliminary design is a mechanism that can meet the requirement of placing a pile every 0.8m. Other pile distances can be realized by changing the internal transmission mechanism according to specific needs.
