Description

Technical Field

[0001] The invention belongs to the technical field of electromechanical installation construction, and in particular relates to a novel electromechanical pipeline construction transport trolley and a use method thereof. Background Art

[0002] my country's construction industry has been booming for 30 years. Buildings with different functions and purposes have gradually enriched our lives. The mechanical and electrical pipeline installation tools that meet the needs of construction sites are also constantly being updated, moving towards a more practical direction that adapts to the actual construction environment on site.

[0003] Existing applications for transporting pipes, such as CN202020269560.8, are a pipe transport system for construction. Two sets of pipe transport devices are used to fix and transport the pipes from both ends of the pipes. However, the disadvantage is that only a single pipe can be transported, which is inefficient.

[0004] CN202322496345.8, a moving mechanism of a pipeline transport trolley, one end of the moving mechanism is provided with a pipeline limiter that cooperates with the moving mechanism to complete the work, and the other end of the moving mechanism is provided with a push-pull component that facilitates the movement of the moving mechanism. Its disadvantage is that it can only transport a single pipeline, and the pipe diameter and length are limited.

[0005] CN202221976257.7, a multifunctional water conservancy project pipeline transporting device, which uses a base and a pallet to place the pipeline during transportation, and can stably limit each pipeline to avoid damage or falling of the pipeline during transportation, which is beneficial to improving the practicality of the transporting device. The disadvantage is that the whole vehicle is bulky and cannot realize remote control of the power, which will have a serious impact on the construction efficiency.

[0006] Based on the above patents and the actual construction site conditions, the following problems are summarized when using pipeline handling tools:

[0007] 1. The number, volume and weight of pipes carried at a time are limited when carried by hand, and manual handling is the only option, resulting in low construction efficiency and failure to meet the requirements of efficient construction.

[0008] 2. The use of hydraulic trucks to transport pipes is limited by the fact that hydraulic trucks are unpowered devices and require human labor to pull them, which reduces construction efficiency. Moreover, if the pipes exceed a certain weight or length, the hydraulic truck carrying the pipes cannot be moved by human labor.

[0009] 3. When using a forklift to transport pipes, the pipes are easy to roll and slide on the fork angle of the dismantling truck, which is very unsafe. In addition, forklifts usually transport pipes horizontally. The length of electromechanical pipes generally ranges from 6m to 12m. Pipes transported by forklift cannot pass through narrow passages.

[0010] 4. Although using a small crane to transport pipes can meet the requirements of carrying weight and quantity, the use environment is limited. The crane can only be used in open spaces and is not suitable for pipes that have been unloaded into floor passages.

[0011] Therefore, in order to solve the above problems, a mechanical and electrical pipeline construction transport trolley is urgently needed. Summary of the invention
