Problems solved by technology

Due to the crowded production roads in the factory, a large number of production vehicles drive every day, and it is impossible to break the road and occupy the assembly for a long time
Therefore, there are the following disadvantages in this assembly method of the prior art: 1. In the process of making and assembling into a whole, modular transportation and hoisting are all difficult and costly tasks; 2. Long assembly time leads to Parts occupy the construction site for a long time
[0003] In summary, the prior art still lacks an efficient and low-cost method for the overall transportation of long-span corridor trusses

Embodiment 1

[0040] Such as Figure 1-2 As shown, a schematic diagram of hoisting and transportation in a large-span corridor truss overall transportation method is shown, including a corridor truss 1 , a crawler crane 2 , and a pallet truck 3 . The overall transportation method of the corridor truss is briefly summarized as the following steps:

[0041] S1. Selection of assembly site, choose a site suitable for assembly;

[0042] S2, assembling, assembling corridor trusses;

[0043] S3. Hoisting. Use a crawler crane to lift the corridor truss assembled in step S2 off the ground, and reverse the two trolleys back and forth to under the corridor truss, so that the portal frame of the corridor truss is located lowered onto the cart;

[0044] S4, transportation, two pallet trucks start at the same time, one moves forward and the other retreats, and transports the corridor truss to the hoisting position;

[0045] S5. Unloading: use a crawler crane to unload the corridor truss, hoist the co...

Embodiment 2

[0051] Construction environment and requirements: The engineering project of the entire blast furnace feeding and returning system is mainly composed of corridor structure and commissioner's station. The corridor along the Weisan section of the road in the factory area is a sinter corridor and a blast furnace return corridor. The average length of the corridor is 24m, of which two sections are 60m long.

[0052] Adopt the traditional method: first transport the scattered components to the hoisting area for assembly. The assembly time is 10 days, and the hoisting is 2 days. It is necessary to close the Weisan Road and Jinger Road in the factory area for 15 days. According to the evaluation of the owner, if the road is closed for 15 days, it will affect production. , a loss of about 6 million.

[0053] Using the method provided in Example 1: put the assembly site at a position about 800m away from the hoisting position and assemble it into a whole, and then transport it to the h...

Embodiment 3

[0056] Construction environment and requirements: The corridor passes through Weisan Road. The length of the corridor is 47m, the height is 7.5m, and the weight is 220 tons.

[0057] Adopt the method of Example 1 for construction and transportation, overcome the impact of narrow site and road blockage, save 100,000 yuan for two shifts of special vehicles, and reduce the production loss of 2.8 million yuan.

[0058] In summary, the method of the present invention has the following advantages: 1. The 17.5m pallet truck belongs to a commonly used transport vehicle, which is convenient to rent, and the rental price is cheap, while the rental cost of special low-board vehicles used in the prior art is high, and it is not easy Find the vehicle source, and the manufacturer is unwilling to rent short-term; 2. The floor of the 17.5m pallet truck is high and limited by the terrain, while the distance between the floor and the ground of the special low-board vehicle required by the existi...

Abstract

The invention discloses a large-span vestibule truss integral transportation method. The large-span vestibule truss integral transportation method comprises the following steps that S1, an assembling site is selected, specifically, the site suitable for assembling is selected; S2, assembling is conducted, specifically, a vestibule truss is assembled; S3, hoisting is conducted, specifically, the vestibule truss assembled in the step S2 is hoisted away from the ground through a crawler crane, two platform plate trailers slowly back to the position below the vestibule truss in the front-back direction, a portal of the vestibule truss is located in the center of rear wheels of the platform plate trailers, and the vestibule truss is slowly lowered onto the platform plate trailers; S4, transportation is conducted, specifically, the two platform plate trailers are started simultaneously, one platform plate trailer moves forwards, the other platform plate trailer moves backwards, and the vestibule truss is transported to the hoisting position; and S5, unloading is conducted, specifically, the vestibule truss is unloaded through the crawler crane, the platform plate trailers are driven away after the vestibule truss is hoisted away from the platform plate trailers, and then the vestibule truss is put down. The large-span vestibule truss integral transportation method is efficient and low in cost.

Description

technical field [0001] The invention relates to the technical field of transportation equipment, in particular to an integral transportation method for large-span corridor trusses. Background technique [0002] The large-span corridor truss mobile transportation technology is a construction technology developed and used in the construction process of the project. In the previous construction scheme of long-span corridor trusses, they were all fabricated in sections and assembled on site. Due to the crowded production roads in the factory, a large number of production vehicles drive every day, and it is impossible to break the road and occupy the assembly for a long time. Therefore, there are the following disadvantages in this assembly method of the prior art: 1. In the process of making and assembling into a whole, modular transportation and hoisting are all difficult and costly tasks; 2. Long assembly time leads to Parts occupy the construction site for a long time. [...
