Track folding dynamic self-retracting type sandpit circulating self-supporting leveling device

Abstract

The invention discloses a track folding dynamic self-retracting type sandpit circulating self-supporting leveling device which comprises a sand surface connected dynamic balance circulating leveling mechanism, a folding portable guide track and a continuous crossing stable walking mechanism, and the continuous crossing stable walking mechanism is clamped on the folding portable guide track in a rolling mode. The sand surface connected dynamic balance circulating leveling mechanism is fixedly arranged on the upper wall of the continuous crossing stable walking mechanism in a penetrating mode. The invention belongs to the technical field of sports goods, and particularly provides a track folding dynamic self-retracting type sandpit circulating self-supporting leveling device which applies a self-service principle and a dynamic characteristic principle to automatic leveling of uneven positions on the surface of a sandpit to achieve intelligent dynamic leveling of the surface of the sandpit. According to the folding portable guide rail, the segmentation principle is applied, the turnover performance of sandpit leveling equipment is improved, the maintenance cost of the equipment is reduced, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention belongs to the technical field of sporting goods, in particular to a track-folding dynamic self-retracting type bunker circulating self-sufficient leveling device. Background technique [0002] Long jump, also known as rushing long jump, is a jumping event in track and field sports. The current long jump training competition is carried out in a sand pit. The long jumper's performance is reflected through the contact point between the long jumper and the fine sand in the sand pit. The sand pit improves the safety of long jump sports, but Each jump will leave a pit mark on the fine sand, which will affect the accuracy of subsequent performances. Therefore, the fine sand needs to be leveled repeatedly, which significantly increases the workload. [0003] The existing sand pit leveling device has the following problems: [0004] 1. The manually operated leveling device requires a lot of manpower, and the level of the operators is uneven, and...

AI Technical Summary

Problems solved by technology

[0004] 1. The manually operated leveling device requires a lot of manpower, and the level of the operators is uneven, and the leveling error of the bunker is relatively large;

[0005] 2. The automatic leveling device needs to be equipped with fixed guide rails along the length of the bunker. The size of the equipment is large and cannot be moved. If i
