All-in-one assembling machine for road construction

Abstract

The invention relates to construction equipment for urban road construction, in particular to a high-efficiency assembling special all-in-one machine used for pre-assembling-type road base construction. The all-in-one machine comprises a truss, a main crane, crawler-type walking mechanisms, cantilever crane assemblies and an electric control cabinet, wherein the truss consists of a main transverse beam and two herringbone vertical beams which are respectively arranged at two ends of the main transverse beam; the main crane is arranged on the main transverse beam of the truss; the crawler-type walking mechanisms are respectively arranged under the herringbone vertical beams; each cantilever crane assembly is arranged on one side of the corresponding herringbone vertical beam; each cantilever crane assembly consists of a single column, a single-column rotating motor, a cantilever arranged on the single column, and a cantilever crane arranged on the cantilever; each crawler-type walking mechanism consists of a walking mechanism rack body and two triangular crawler assemblies arranged under the walking mechanism rack body. The all-in-one machine disclosed by the invention adopts a gantry type framework structure, is reasonable in arrangement, safe and reliable to use, convenient to load and unload, high in laying efficiency, and simple to operate; the all-in-one machine can be widely applied to the laying of prefabricated concrete blocks in municipal construction, the laying construction of prefabricated concrete inspection wells, and the laying construction of underground pipelines.

Description

technical field [0001] The invention relates to a construction equipment for urban road construction, in particular to a special all-in-one machine for high-efficiency assembly for prefabricated road base construction. Background technique [0002] The construction sequence of the road base in the current urban road construction is mainly: excavation of the foundation→measurement and lofting→installation of formwork→concrete mixing→concrete transportation→paving and vibration→full surface and formwork removal→maintenance. In road construction and maintenance projects, in order to reduce the interference of construction on urban life, resume traffic as soon as possible, and complete construction operations in a short period of time, prefabricated concrete blocks for concrete bases that replace traditional concrete cast-in-place construction were developed in the early stage.

Problems solved by technology

In road construction and maintenance projects, in order to reduce the interference of construction on urban life, resume traffic as soon as possible, and complete construction operations in a short period of time, prefabricated concrete blocks for concrete bases that replace traditional concrete cast-in-place construction were developed in the early stage. In actual projects During the pavement test, it was found that due to the lack of special machinery, many problems such as efficiency and cost were found in the process of paving with truck cranes. Equipment) takes up a lot of space in the plane and vertical directions, and requires a large site for parallel assembly. The narrow road surface cannot be constructed, and the requirements for half-width road operations and half-width road traffic cannot be realized; the empty return distance of the crane arms of the tandem assembly is long and the efficiency is low.

②. Sufficient clearance conditions are required. Since there are many power cables and communication and other pipe network infrastructures above the urban roads, it is easy to touch the cables during construction, resulting in power outages or even electric shock hazards, and affecting surrounding residents, businesses, etc. and similar events

③. Intermittent operation. Due to the limitation of the crane arm length during the assembly operation, the crane needs to be moved once for laying a section: retracting the arm, retracting the leg, moving, retracting, and extending the rod. It takes more than 10 minutes to move each time, regardless of whether it is parallel when unloading The operation is still a tandem operation. The crane must be moved every time a car of prefabricated blocks is unloaded, and the assembly efficiency is low. The average prefabricated block assembly (net) time is 2 minutes, and the car is moved every 4 rows, 96 minutes + 15 minutes, 27 hours of assembly per hour. piece

④, comprehensively lead to high assembly costs and increase the overall cost of road construction
