Abstract

A sliding trolley for installing an air pipe in a limited area belongs to the technical field of installation of large-scale ventilation pipelines in sports stadiums. Comprises a top joist (1), a middle joist (2), a bottom joist (3), rolling wheels (4) and rolling wheel shafts (9); the top joist (1) is welded with the middle joist (2), the middle joist (2) is welded on the bottom joist (3), the two bottom joists (3) are connected and welded by the rolling wheel shaft (9), and the rolling wheel (4) is arranged below the bottom joist (3). The method has the advantages that the installation of the air pipes in the limited area is simple and easy to operate, the roof panel is prevented from being dismantled and restored, labor, time and mechanical machine shifts are saved, and the construction cost is greatly reduced.

Description

Sliding trolley for installing air pipe in limited area

Technical Field

The utility model belongs to the technical field of the installation of the large-scale air pipe in sports stadium, especially, a sliding trolley who installs the tuber pipe in the restriction region and use is provided.

Background

When the large-scale ventilation duct of sports stadium is installed, for the tuber pipe on the platform of stadium top, because the later stage installation, all demolish partial roofing roof, reuse large-scale hoisting equipment and hoist the tuber pipe and take one's place, resume the roofing after the tuber pipe takes one's place to install, take a lot of work, waste time, take mechanical shift, increased construction cost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sliding trolley that installation tuber pipe used in the limitation region, when venue top tuber pipe erection construction, use a sliding trolley, the tuber pipe that will install in advance is chosen from the venue tip and is placed on sliding trolley on the temporary platform outward, sliding trolley lays on the guide rail, bottom roll wheel and guide rail contact under the slip, and form and slide, then utilize the hoist to stimulate to slide and get off, after sliding trolley moves tuber pipe mounted position, recycle top chain fall and hang the tuber pipe from the slip and get off, the hoist drives and drags from sliding trolley, the tuber pipe installation is taken one's place.

The utility model discloses a top joist 1, middle part joist 2, bottom joist 3, roll wheel 4, roll wheel axle 9. The top joist 1 is welded with the middle joist 2, the middle joist 2 is welded on the bottom joist 3, the rolling wheel shaft 9 is connected with and welded with the two bottom joists 3, and the rolling wheel 4 is arranged below the bottom joist 3. The top joist 1, the middle joist 2, the bottom joist 3 and the rolling wheel 4 are all two. (see FIGS. 1 and 2)

The top joist 1 is an I-shaped steel section, and the top surface of the I-shaped steel is processed into an arc surface; the middle joist 2 and the bottom joist 3 are both rolled H-shaped steel.

The method comprises the steps that a pre-installed air pipe 5 is picked out from the end part of a venue and placed on a temporary platform on a joist at the top of a sliding trolley 1, the sliding trolley is placed on a guide rail 6, a rolling wheel 4 at the bottom of the sliding trolley is in contact with the guide rail 6 to form sliding (shown in figures 3 and 4), then the sliding trolley is pulled by a winch 7 to slide to get off (shown in figure 5), when the sliding trolley runs to the installation position of the air pipe 5, the air pipe is lifted away from the sliding trolley by a top chain block 8, the winch 7 is driven to be pulled away from the sliding trolley, and the air pipe 5 is.

The use of the sliding trolley enables the installation of the air pipe in the limited area to be simple and easy to operate, avoids the dismantling and the recovery of the roof panel, saves labor, time and mechanical machine shifts, greatly reduces the construction cost and obtains good economic benefit for companies.

Detailed Description

Fig. 1-6 show a specific embodiment of the present invention. The present invention will be further explained with reference to the accompanying drawings.

The utility model discloses a top joist 1, middle part joist 2, bottom joist 3, roll wheel 4, roll wheel axle 9. The top joist 1 is welded with the middle joist 2, the middle joist 2 is welded on the bottom joist 3, the rolling wheel shaft 9 is connected with and welded with the two bottom joists 3, and the rolling wheel 4 is arranged below the bottom joist 3. (see FIGS. 1 and 2)

The method comprises the steps that a pre-installed air pipe 5 is picked out from the end part of a venue and placed on a temporary platform on a joist at the top of a sliding trolley 1, the sliding trolley is placed on a guide rail 6, a rolling wheel 4 at the bottom of the sliding lower car is in contact with the guide rail 6 to form sliding, then the sliding lower car is pulled by a winch 7, after the sliding trolley runs to the installation position of the air pipe 5, the air pipe is lifted away from the sliding lower car by a top chain block 8, the winch 7 is driven to be pulled away from the sliding trolley, and the air pipe 5 is installed in.
