Crawler-type carrier vehicle

Abstract

The invention relates to a traffic and transport means, in particular to a crawler-type carrier vehicle. The invention provides the crawler-type carrier vehicle which is provided with a front portal frame component and a back portal frame component, the positions of which can be adjusted, wherein transported building materials and the like are arranged on the front and the back portal frame components; the upward movement, the downward movement, the left movement and the right movement of the front and the back portal frame components can be realized under the actions of a translation drivingcomponent and a lifting driving component, therefore, the building materials can be moved upwards, downwards, to the left and to the right according to the specific transportation conditions of the carrier vehicle, so that the center of gravity of the carrier vehicle is changed and the running dynamics of the whole vehicle during transportation is balanced to conform with the road condition and the condition of the carrier vehicle, thus easily realizing one-time variable speed turning, playing important role in adjusting the center of gravity of the carrier vehicle when ascending or descending, greatly improving the transportation efficiency, improving the safety performance of the carrier vehicle, and being consistent with the requirements of safe production and construction; and the crawler-type carrier vehicle is an innovative invention in the filed of the crawler-type carrier vehicle, thus having significant meaning.

[0002] Chinese patent ZL200610031819.X discloses a fully hydraulic driving method and device for rubber crawler transportation, and discusses that in the prior art, transportation in mountainous and hilly areas is a very difficult problem

For example, in the construction of some electric power and communication, it is often necessary to build base stations and erect lines in uninhabited areas. However, these areas are uninhabited and roads are not developed. The traffic conditions are very bad, often bumpy, steep, and road conditions are very poor. Poor, building materials need to be carried to the designated place by manpower, or rented local caravans, the efficiency is extremely low, so the construction time is also long. The construction of electric power, communication and other industries in China is extremely unfavorable

[0003] The above-mentioned patent adopts a full-hydraulic driving method and device for crawler belt transportation, which solves the above-mentioned problems. However, the disadvantage of this technology is that although it changes or cuts off the flow of pressure oil flowing to the motor through the adjustment mechanism on the motor, thereby Change the movement speed of the left and right motors of the machine to solve the problem of changing the direction of the machine in the transport direction, but it does not take into account that the building materials with a certain weight on the transport vehicle are fixed and installed. Under severe traffic conditions, the heavy building materials may make the transport When the vehicle changes speed, it produces too much centripetal force or centrifugal force, which makes it difficult for the transport vehicle to complete the variable speed turning at one time. The installation causes the center of gravity of the transport vehicle to be fixed. When going uphill or downhill, once the slope is too large, the transport vehicle will not escape the misfortune of overturning, which will have a great impact on the personal safety of the transport vehicle driver.
