Description

Split lifting construction trolley

technical field

The utility model relates to a construction trolley, in particular to a split lifting construction trolley.

Background technique

At present, in the construction of hydropower projects, construction trolleys are mostly used for cavern support and grouting. Since the height of the construction trolley is fixed, when the elevation of the excavation surface of the cavern changes, the construction trolley needs to be remade or refitted, not only Increase the cost input, and affect the construction progress.

Contents of the invention

The technical problem to be solved by the utility model is to provide a split-type elevating construction trolley device, which can overcome the problem of remaking or refitting the construction trolley when the elevation of the working surface changes, and has a simple structure and is easy to operate.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a split lifting construction trolley, including a lower working platform,

The lower working platform is combined with the upper working platform through the connecting frame to form an overall structure;

The connecting frame body is composed of multiple sets of vertically adjustable devices and multiple horizontal connecting rods connecting two sets of vertically adjustable devices;

In the vertically adjustable device, the first rod is fixedly connected to the top of the lower working platform, the second rod is fixedly connected to the bottom of the upper working platform, the second rod is sleeved in the first rod, and the second rod is connected to the first rod. A rod is fixed by multiple sets of bolts.

An oblique support rod is also arranged between the second rod and the upper working platform.

A plurality of elliptical holes are drilled equidistantly in the middle of the first rod, and a plurality of circular holes are drilled equidistantly in the middle of the second rod.

A first climbing ladder is arranged on the lower working platform, and a second climbing ladder is arranged between the lower working platform and the upper working platform.

The first rod is fixedly connected to the top of the lower working platform through bolts.

The split-type lifting construction trolley provided by the utility model can adapt to the change of the elevation of the working surface by adjusting the height of the vertical adjustment device connecting the frame body and the height of the upper working platform, and solves the problem of remaking or refitting the construction trolley. The problem is that the setting structure is simple and easy to operate, which can reduce the construction cost and speed up the construction progress; the first rod and the top of the lower working platform are fixedly connected by bolts, which is easy to dismantle. After removing the upper working platform and the connecting frame body, the lower working platform can be used independently, achieving the effect of one thing with multiple functions.

Detailed ways

As shown in Figures 1-5, a split-type lifting construction trolley includes a lower working platform 1,

The lower working platform 1 is combined with the upper working platform 2 through the connecting frame body 3 to form an overall structure;

The connecting frame body 3 is composed of multiple sets of vertically adjustable devices and multiple transverse connecting rods 6 connecting two sets of vertically adjustable devices;

In the vertically adjustable device, the first rod 4 is fixedly connected to the top of the lower working platform 1, the second rod 5 is fixedly connected to the bottom of the upper working platform 2, and the second rod 5 is sleeved in the first rod 4. The height of the upper working platform 2 can be adjusted; the second bar 5 and the first bar 4 are connected and fixed by multiple sets of bolts 7 .

An oblique supporting rod 12 is also arranged between the second rod 5 and the upper working platform 2 .

The lower working platform 1 and the upper working platform 2 are preferably frame-structured working platforms made of profiled steel. Platform boards are arranged on the top of the platform, and there are guardrails around to facilitate construction workers' operations and ensure the safety of operators.

The first rod 4 and the second rod 5 are preferably channel steel or square steel members. In this embodiment, the first rod 4 is preferably No. 20 channel steel, and the second rod 5 is preferably No. 18 channel steel.

A plurality of elliptical holes 8 are equidistantly drilled in the middle of the first rod 4 , and a plurality of circular holes 9 are drilled equidistantly in the middle of the second rod 5 , and the pitch and diameter of the elliptical holes 8 and circular holes 9 are equal.

A first climbing ladder 10 is arranged on the lower working platform 1, and a second climbing ladder 11 is arranged between the lower working platform 1 and the upper working platform 2, which is convenient for construction workers to go up and down.

The first bar 4 is fixedly connected to the top of the lower working platform 1 by bolts, so that the lower working platform 1 can be used independently after the bar is removed.

The working steps of the present utility model are as follows:

Use the lower working platform 1 of the present utility model to carry out operations such as cavern support and grouting. When the height of the construction work surface increases, the upper working platform 2 and the connecting frame body 3 are installed on the upper part of the lower working platform 1, and the second rod member 5 is adjusted. The length extending into the inside of the first rod 4, when the height of the upper working platform 2 meets the height of the working surface, use the bolt 7 to connect and fix the first rod 4 and the second rod 5 firmly, so that the trolley can be moved Heightened. When the height of the working surface changes again and increases (decreases), hang the upper working platform 2 with a truck crane, loosen the bolts 7 connecting the first rod 4 and the second rod 5, and the upper working platform 2 follows the second The rod 5 slides up (down) in the first rod 4, and the upper working platform 2 rises (down) to the specified height, and is connected and fixed with the bolt 7 again, so that the construction trolley can be quickly and safely lifted.
