Description

Shield constructs quick-witted section of thick bamboo supporting mechanism

Technical Field

The utility model relates to a shield machine duct piece supporting mechanism.

Background

The pipe sealing piece in the pipe piece of the shield tunneling machine is easily influenced by surrounding soil or underground water to cause a falling phenomenon, so that the through hole for penetrating a screw on the pipe sealing piece and the through holes on the long pipe pieces on two sides are staggered, and the arc-shaped screw rod is difficult to penetrate between the pipe sealing piece and the long pipe pieces.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a shield tunneling machine segment supporting mechanism which is used for solving the problem that a shield tunneling machine segment falls down.

In order to solve the problems, the technical scheme of the utility model is as follows:

the utility model provides a shield constructs quick-witted section of jurisdiction supporting mechanism, includes a supporting beam, and a supporting beam both ends are respectively through adjustment mechanism and section of jurisdiction fixed connection, installs elevating system on a supporting beam, and the elevating system lift is served and is connected with the arc roof, and elevating system drive roof supports and leans on the section of jurisdiction.

Preferably, the adjusting mechanism comprises a portal with the lower end hinged with the supporting beam, and the upper end of the portal is connected with the segment hoisting hole through a screw.

Preferably, the lifting mechanism comprises a three-shaft bevel gear box fixedly connected to the supporting beam, the supporting beams on two sides of the three-shaft bevel gear box are respectively provided with a screw rod lifter, and output shafts on two sides of the three-shaft bevel gear box are respectively in transmission connection with the two screw rod lifters.

Preferably, a ribbed plate is fixedly connected to the arc-shaped top plate and is hinged to the lifting end of the screw rod lifter.

Preferably, a rubber plate is fixedly connected to the top plate.

The utility model has the beneficial effects that: after being connected a supporting beam and a long pipe piece on the two sides of the pipe sealing piece, the supporting beam supports the lifting mechanism, and then the lifting mechanism drives the top plate to support the pipe sealing piece so as to disperse the load of the pipe sealing piece onto other long pipe pieces, thereby preventing the pipe sealing piece from falling down on the one hand, and ensuring that the through holes of the screw through holes of the pipe sealing piece and the long pipe pieces cannot be dislocated on the other hand, thereby ensuring the quality safety of the shield tunnel.

Drawings

The utility model is further described below with reference to the accompanying drawings:

fig. 1 is a schematic front view of the present invention.

Fig. 2 is a left side view of the present invention, in which the elevating mechanism is not shown.

Fig. 3 is a schematic structural diagram of the lifting mechanism according to the present invention.

In the figure: long section of jurisdiction 1, portal 2, rubber slab 3, roof 4, a section of jurisdiction 5, floor 6, a supporting beam 7, triaxial bevel gear case 8, lead screw lift 9.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1 to 3, a shield constructs quick-witted section of jurisdiction supporting mechanism, a supporting beam 7 that square steel pipe made, supporting beam 7 both ends are respectively through adjustment mechanism and the long section of jurisdiction fixed connection in a tub piece both sides, install elevating system on supporting beam 7, and the last arc roof 4 that is connected with of elevating system lift end, and elevating system drive roof 4 supports and leans on the section of jurisdiction.

When the device is used, the lifting mechanism drives the top plate 4 to abut against the duct sealing piece 5 and the long duct piece 1, and the support beam 7 supports the duct sealing piece so as to prevent the duct sealing piece 5 from falling.

The adjusting mechanism comprises a portal 2, the lower end of the portal 2 is hinged to the supporting beam 7, and the upper end of the portal 2 is connected with the segment hoisting hole through a screw. The lifting hole and the standard dimension on the long pipe piece on the two sides of the pipe sealing piece can have a certain error, if the supporting beam 7 is directly connected with the long pipe piece through the screw, the screw can be difficultly screwed into the lifting hole due to the error, so that an adjusting mechanism is arranged, the adjusting mechanism can compensate the error, and a worker can install the supporting beam 7 quickly.

Elevating system includes triaxial bevel gear case 8 of fixed connection on a supporting beam 7, installs lead screw lift 9 on a supporting beam 7 of triaxial bevel gear case 8 both sides respectively, and triaxial bevel gear case 8 both sides output shaft is connected with two lead screw lift 9 transmissions respectively. During the use, the staff can use electric spanner with its input shaft in with triaxial bevel gear case 8, then goes up and down simultaneously through two lead screw lift 9 of triaxial bevel gear case 8 drive, realizes the quick support to the section of jurisdiction.

A ribbed plate 6 is fixedly connected to the arc-shaped top plate 4, and the ribbed plate 6 is hinged to the lifting end of the screw rod lifter 9. The rib 6 serves to increase the strength of the top plate 4.

A rubber plate 3 is fixedly connected to the top plate 4. The rubber plate 3 can not damage the shield segment in the supporting process and can better bear force uniformly.
