A hydraulic grabbing mechanical arm for anti-collapse rock-soil retaining wall

Abstract

The invention relates to a hydraulic grabbing mechanical arm for an anti-collapsing rock-soil retaining wall. The hydraulic grabbing mechanical arm comprises a damping supporting mechanism, wherein the damping supporting mechanism comprises a fixed platform; three parallel-connection branch chains are evenly mounted on the upper end face of the fixed platform in the direction of the axis, and the top ends of the three parallel-connection branch chains are mounted on the lower end face of a movable platform; each parallel-connection branch chain comprises a concave support welded to the upper end face of the fixed platform, a lower limiting shaft is mounted between middles of two sides of each concave support, and two arc limiting grooves are symmetrically formed in the inner wall of the upper end of each concave support; each lower limiting shaft is sleeved with a first hydraulic cylinder, two limiting rods are arranged on the two sides of the bottom end of each first hydraulic cylinder, and the tail ends of two limiting rods are connected with corresponding two arc limiting grooves in a sliding fit manner; and a hydraulic grabbing device is mounted at the upper end face of the movable platform. According to the mechanical arm, the stable automatic hydraulic grabbing function of masonry can be achieved, the phenomenon of vertical shaking or left-and-right shaking in the carrying process can be avoided, and stability performance is good.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a hydraulic grabbing mechanical arm for anti-collapse rock-soil retaining walls. Background technique [0002] There are generally retaining walls on both sides of the expressway section and the urban highway section near the mountain. The types of retaining walls are divided into two types: masonry retaining walls and concrete retaining walls. The main functions of the retaining walls are: 1. Support roadbed filling or hillside soil; 2. Prevent filling or soil deformation and instability; 3. Prevent landslides and landslides, so retaining walls play a vital role in road safety; The earth walls are all set up next to the mountain, and the raw materials for masonry masonry are abundant, so the masonry masonry retaining wall is mainly used. The grouted masonry is manually grabbed and placed in the transport trolley, the operator pushes the trolley to the conveying...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a hydraulic grabbing mechanical arm for anti-collapse rock-soil retaining walls, which can solve the problems of the existing artificial stacking methods of retaining walls that require manual full-process operation, low construction efficiency, and serious safety hazards , During the masonry handling process, there are problems such as shaking up and down or left and right, poor stability, manual grabbing of the masonry, high labor intensity, slow grabbing speed and low grabbing efficiency, etc., which can realize the stability of the masonry The hydraulic automatic grab function eliminates the phenomenon of shaking up and down or left and right during the handling process. It has good stability, high construction efficiency, and no potential safety hazards. Take advantage of high efficiency
