Embodiment Construction

[0018] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.

[0019] image 3 It is a schematic diagram of a support base provided by the present invention. The support base includes a central disc 1, and one end of three near support claws 2 is uniformly mounted on the central disc 1 through a hinge, and can be put down and folded. Among the three near support claws 2, one is longer than the other two, and is used to prevent the device from tilting.

[0020] The front end of the far support claw 3 is connected with the other end of the near support claw 2 by a hinge 8, and the first slider 9 is equipped with the hinge 8 front portion on the far support claw 3, and the second slider 9 is equipped with the hinge 8 front portion on the near support claw 2. The block 7, the first slider 9 and the second slider 7 are connected by a connecting rod 6. When positioning is required, the bolts 10 o...

Abstract

The invention provides a supporting base. The supporting base is characterized by comprising a center round disk; one end of each of three near support pawls is evenly arranged on the center round disk, and one end of each of three remote support pawls is moveably connected to the other end of each of the three near support pawls; a fan-shaped baffle is coaxially arranged at the upper part of the center round disk, the center of the upper part of the center round disk is provided with a spherical pair. By adopting the supporting base, shortcomings of the prior art are overcome; due to the supporting pawls capable of adjusting angle, the grounding state is adjusted very good, the contact area with the ground is enlarged, and the supporting scope is expanded; the supporting base is suitable for a relatively complex pavement; moreover, the device is simple and flexible in structure and strong in maneuverability.

Description

technical field [0001] The invention relates to a support base, which belongs to the technical field of support bases of engineering vehicles. Background technique [0002] Engineering vehicles are the backbone of engineering construction. Due to construction requirements, only when engineering vehicles can be positioned stably can they carry out relevant engineering operations reliably. Such as figure 1 with figure 2 As shown, existing engineering vehicles all rely on four disc-shaped bases with smaller diameters to contact and locate with the ground. However, only when the disc-shaped base bears the force in the vertical direction can it be positioned stably. This disc-shaped base has a small contact area with the ground and can only be used on flat roads. It has poor adaptability to slope roads, and when it is subjected to a large rolling force during construction, it is easy to cause the rollover of the engineering vehicle. Contents of the invention [0003] The ...
