Abstract

The invention relates to a rectangular jacking pipe for a pipe jacking construction machine. The rectangular jacking pipe comprises a rectangular shell of the rectangular jacking pipe, a mud water bin is formed on the right side of the rectangular shell, and a work chamber is formed on the left side of the rectangular shell. Motors A and B are arranged in the work chamber. Other parts such as excavation cutter heads, cutting heads, sprocket wheels and caterpillars are arranged in the mud water bin. Four motors A are arranged at the four corners of the rectangular section of the jacking pipe respectively. The right end of each motor A is connected to a cutter head A through a short shaft A. The sprocket wheels are arranged on the short shafts A. The caterpillars are wound on the four sprocket wheels. Cutting heads A are arranged on the caterpillars. The motor B is arranged in the center of the rectangular shell of the jacking pipe, and is connected to a cutter head B through a short shaft B. A plurality of cutting heads B are arranged on each of the cutter heads A and B. The cutting heads on the caterpillars are used for cutting along the rectangular section, and a cut cross section is a standard rectangle, so that the resistance is low during pipe jacking, and construction is facilitated.

Description

Rectangular top pipe

One, technical field

The present invention relates to a kind of push pipe, particularly a kind of rectangular top pipe of jacking construction machinery.

Two, background technology:

At present, the rectangular top pipe construction machinery all is to form an approximate rectangle cutterhead with the drill bit of a plurality of circles, during the rectangle cutting face of this knife cutting rectangular top pipe, have a lot of knife cuttings less than the place, resistance is big especially during push pipe, constructional difficulties.

Three, summary of the invention:

The present invention has remedied the shortcoming of above pipe jacking equipment, and the rectangular top pipe of the full section cutting of a kind of ability is provided.

The present invention realizes through following technical scheme:

A kind of rectangular top pipe comprises the rectangular housing of rectangular top pipe, the muddy water storehouse on the right, the work chamber on the left side; Motor A, motor B all are located in the work chamber, and other excavation cutterhead, cutter head and sprocket wheel, chain rail all are located in the muddy water storehouse, and work chamber and muddy water storehouse are separated by partition panel; Motor A is four, and be located at the push pipe square-section respectively four jiaos, every motor A right-hand member is connected in cutterhead A through minor axis A; Each minor axis A is provided with sprocket wheel, and around the chain rail, the chain rail is provided with cutter head A on four sprocket wheels; Motor B is located in the middle of the push pipe square-section, and motor B is connected in cutterhead B through minor axis B, is equipped with several cutter heads B on cutterhead A, the cutterhead B.

The present invention has following characteristics:

The present invention adopts the cutter head on the chain rail to cut along the square-section, and the cross section of cutting is the rectangle of a standard, and the resistance that receives during push pipe is little, easy construction.

Four, description of drawings:

Below in conjunction with accompanying drawing the present invention is further described:

Fig. 1 is a structural representation of the present invention.

Fig. 2 is a lateral view of the present invention.

Among the figure: 1, motor A, 2, motor B, 3, sprocket wheel, 4, the chain rail, 5, cutter head A, 6, cutterhead A, 7, cutterhead B, 8, cutter head B, 9, partition panel, 10, housing, 11, work chamber, 12, the muddy water storehouse, 13, minor axis A, 14, minor axis B.

Five, the specific embodiment:

Accompanying drawing is a kind of specific embodiment of the present invention, and this embodiment comprises the rectangular housing 10 of rectangular top pipe, the muddy water storehouse 12 on the right; The work chamber 11 on the left side, motor A, motor B all are located in the work chamber, and other excavation cutterhead, cutter head and sprocket wheel, chain rail all are located in the muddy water storehouse; Work chamber and muddy water storehouse are separated by partition panel, and motor A1 is four, be located at the push pipe square-section respectively four jiaos; Every motor A right-hand member is connected in cutterhead A6 through minor axis A13, and each minor axis A is provided with on 3, four sprocket wheels of sprocket wheel around chain rail 4; Chain rail 4 is provided with cutter head A5; Motor B2 is located in the middle of the push pipe square-section, and motor B is connected in cutterhead B7 through minor axis B14, is equipped with several cutter heads B8 on cutterhead A, the cutterhead B.

When the present invention worked, motor B drives cutterhead B just to be changeed, and when four motor A drove cutterhead A counter-rotating, also through four chain wheel drive chain rail counter-rotatings, when the chain rail moved along the square-section that four circles are formed, the cutter head on the chain rail cut into rectangle with the cross section of cutting.
