CN-224225175-U - Crawler-type walking structure of cement rotary masonry equipment

Abstract

The utility model relates to a crawler-type walking structure of cement rotary masonry equipment, which comprises a main connecting seat structure and a transmission crawler structure, wherein the main connecting seat is in a splayed shape, and a connecting part is arranged at the upper part of the main connecting seat. A group of overturning oil cylinder assemblies are arranged between the two side ends of the main body connecting seat and each crawler belt driving inner seat structure. The crawler carrying mechanism is optimally designed for the inner cambered surface walking of the rotary kiln. The equipment structure has the requirements of light weight and high adaptability of the running mechanism in the overhaul and monitoring of the kiln. In the adaptation of the reducing position of the kiln body, the angle of the crawler belt is dynamically adjusted, and cambered surfaces with different diameters are attached. The friction pressure of the equipment to the kiln body lining is reduced, the stability is high in use, and the overturning caused by the heart deviation during walking is avoided.

Description

Crawler-type walking structure of cement rotary masonry equipment Technical Field The utility model relates to the field of cement rotary kiln masonry equipment, in particular to a crawler-type travelling structure of cement rotary masonry equipment. Background Along with the development of social economy, the labor cost of the building industry is continuously increased, and the shortage of skilled brickwork workers promotes enterprises to seek automatic brickwork equipment so as to reduce the cost and improve the efficiency. The manual brickwork is easily influenced by the technical level and working state of workers, and the quality stability is poor. The robot can ensure the consistency of brickwork quality, and can operate in dangerous environment, ensure workman safety. The wheel type, crawler type, leg type and other travelling mechanisms are widely applied in the field of mobile robots, and a technical reference is provided for the travelling mechanism of the automatic bricklaying robot. For example, the wheel type travelling mechanism has high speed and efficiency, and the crawler type travelling mechanism has good stability and adapts to complex terrains. Some bricklaying robots designed for complex terrains or severe construction environments can adopt crawler-type travelling mechanisms, such as those used for working on uneven ground such as coal mine tunnels. The crawler-type travelling mechanism has good stability and strong adaptability to the ground, can walk on soft and rugged ground, and is not easy to slip or sink. The existing running gear (such as a pipeline detection robot, kiln maintenance equipment and the like) inside the barrel has the following problems: 1. The adaptability is poor, the crawler belt structure with a fixed angle cannot adapt to cylinder environments with different diameters or obstacles; 2. The adjustment is inflexible, the angle of the crawler belt is manually adjusted after the traditional travelling mechanism is stopped, and the efficiency is low; 3. The stability is insufficient, the inner wall of the cylinder body can have working conditions such as greasy dirt, scaling and the like, and the single-angle crawler belt is easy to slip; 4. the control is complex, the multi-degree-of-freedom adjustment is dependent on a complex transmission mechanism, and the maintenance cost is high. Some bricklaying robots designed for complex terrains or severe construction environments can adopt crawler-type travelling mechanisms, such as those used for working on uneven ground such as coal mine tunnels. The crawler-type travelling mechanism has good stability and strong adaptability to the ground, can walk on soft and rugged ground, and is not easy to slip or sink. The rotary cement kiln cylinder has a variable diameter cambered surface structure (such as a phi 6.96 multiplied by 52m ultra-large kiln body), and the traditional wheel type or fixed crawler running mechanism is difficult to adapt to the diameter change (such as gradual change or abrupt change area from kiln head to kiln tail). The existing equipment walks Shi Yi in the kiln, and friction damage is caused by the fact that the existing equipment is not attached to the cylinder body due to contact, and even the stability of the kiln body is affected. For example, patent CN110979035A proposes a variable diameter arc traveling trolley, but it relies on wheel angle adjustment, and has a complex structure and limited bearing capacity. The wheel type travelling device has the advantages that the wheel angle is required to be frequently regulated, the maintenance cost is high, the surface pressure of the kiln body is unevenly distributed, and the local abrasion is easy to cause. The fixed track mechanism has small ground specific pressure, but is easy to be blocked or slipped in the reducing section due to rigid connection of the track, and has huge volume and difficult adaptation to the space in a narrow kiln. Disclosure of utility model The utility model aims to use a crawler-type travelling mechanism to bear an automatic bricklaying machine in a rotary kiln to move bricklaying. The whole machine is supported by the hydraulic oil cylinder, then the crawler-type travelling wheels are unfolded for a certain angle, and when the crawler-type travelling wheels are uniformly contacted with the inner surface of the cylinder body, the hydraulic oil cylinder is contracted, and the crawler-type travelling mechanism falls on the surface of the cylinder body and can travel in a movable manner. The crawler-type walking structure of the cement rotary masonry equipment comprises a main connecting seat structure and transmission crawler structures arranged on two sides of the main connecting seat structure, wherein the main connecting seat structure is a splayed main connecting seat, connecting components are arranged on the upper portion of the main connecting seat, the transmission crawler structures comprise crawler-driven inner se
