Support base with biasing support legs

Abstract

The invention relates to a support base with biasing support legs. The base consists of at least two support rods and a support pipe, wherein the at least two support rods are respectively hinged on the support pipe; a near-end pulley is arranged at one end, close to the support pipe, of the support rod; a far-end pulley is arranged at one end away from the support pipe; the support legs are also arranged on the support rods in a sliding manner and are connected with a driving mechanism; the support legs are arranged close to the near-end pulleys; the driving mechanism is used for driving the support legs to move up and down to separate from or resist against the ground corresponding to the lower ends of the support legs; a linkage mechanism is also arranged on the base and is used for driving the two support rods to be in an inclined angle increasing or decreasing state; the up-down motions of the support legs coordinate with the change of the inclined angles of the support rods, and the motions and the change can be simultaneously carried out. When the support legs move downwards, the linkage mechanism drives the two support rods to be in the inclined angle increasing state, the occupied area of the support base is increased, the gravity center is fallen in the range of a supporting point to realize stable support of the equipment.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment support, in particular to a support base. Background technique [0002] Many devices in the prior art are arranged on a base. In order to facilitate the movement of the device, universal wheels are generally provided under the base, so that the device can be moved from one position to another conveniently. When the equipment is moved to the designated position, the base needs to be fixed. In the prior art, foot brakes are generally installed on the universal wheels, and the universal wheels are locked by the foot brakes to fix the base. However, the universal wheels are in contact with the ground. The small surface makes the fixation unstable and in some environments it is impossible to lock all the universal wheels on the base at the same time. For some large-scale equipment, in order to ensure the reliability of the base, there are also multiple fixed piles arranged at intervals un...

AI Technical Summary

Problems solved by technology

When the equipment is moved to the designated position, the base needs to be fixed. In the prior art, foot brakes are generally installed on the universal wheels, and the universal wheels are locked by the foot brakes to fix the base. However, the universal wheels are in contact with the ground. The small surface makes the fixation unstable and in some environments it is impossible to lock all the universal wheels on the base at the same time

For some large-scale equipment, in order to ensure the reliability of the base, there are also multiple fixed piles arranged at intervals under the base. When the equipment moves to the designated position, the driving mechanism is used to drive the fixed piles to move down and touch the ground, and then Support the base to improve the reliability of the equipment support. However, in order to ensure that the center of gravity of the equipment is placed within the range of the contact surface between the fixed pile and the ground, the fixed pile is generally set near the outside of the equipment, which increases the occupied space of the equipment. Not suitable for small devices

[0003] In this regard, the applicant applied for a patent application document entitled "A Multifunctional Supporting Base" (Application No.: 2017102477023), which discloses a base that can effectively support equipment. One end is hingedly arranged on the support tube, and the two ends of the two support rods are respectively provided with a proximal support foot and a distal support foot, and the linkage mechanism drives the support rod to rotate around the support feet respectively, and makes the proximal support foot reach the far end The supporting feet at the end show two states of moving up and down and the supporting rods rotating around the supporting feet. When the above-mentioned supporting base is in use, since the supporting tube is arranged above the two supporting rods where the supporting feet are located, the center of gravity of the equipment is mainly concentrated It falls near the support tube, specifically near the support feet. Therefore, during the actual use of the above-mentioned support base, since the center of gravity is too close to the support feet, it is easy to cause the whole equipment to roll over.
