Description

Technical Field

[0001] This utility model relates to the field of shield tunneling technology, and in particular to a shield tunneling machine main unit overall translation device. Background Technology

[0002] In the current construction of underground transportation tunnels, most tunneling is carried out using tunnel boring machines (TBMs). After the tunneling of a section is completed, the receiving shaft often cannot be hoisted, so the tunnel can only be moved a long distance across the platform to the next launching shaft.

[0003] Currently, the main technology for the overall translation of the tunnel boring machine (TBM) involves receiving the TBM from a receiving frame, laying steel plates under the receiving frame and along the translation path, and then using hydraulic jacks to move the receiving frame and the TBM together by welding reaction supports onto the steel plates. However, this method of translating by laying steel plates has technical problems such as high cost, complicated implementation process, high labor input, and low translation efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an overall translation device for the main body of a tunnel boring machine. This translation device does not require the laying of steel plates, which can greatly improve the construction efficiency of tunnel boring machine translation, shorten the construction period, and reduce construction costs.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a shield tunneling machine main unit overall translation device, comprising a shield tunneling machine main unit and a receiving frame, wherein the shield tunneling machine main unit is detachably placed on the receiving frame. The device is characterized by further comprising a lifting cylinder, a translation cylinder, pulleys, and a slide rail. One end of the lifting cylinder is connected to the shield tunneling machine main unit, and the other end is detachably placed on the ground.

The pulley is disposed on one of the shield tunneling machine main unit and the receiving frame, and the slide rail is disposed on the other. The pulley and the slide rail are separately disposed. The lifting cylinder can lift the shield tunneling machine. When the shield tunneling machine main unit is not lifted, the translation cylinder can drive the shield tunneling machine main unit to translate. When the shield tunneling machine main unit is lifted, the pulley and the slide rail are connected to drive the receiving frame to lift synchronously. At this time, the translation cylinder can drive the receiving frame to translate along the slide rail direction.

[0006] As a further improvement of this utility model, it also includes a lifting base, which is fixed on the left and right sides of the shield machine host respectively, and the lifting cylinder is connected to the lifting base of the shield machine host.

[0007] As a further improvement of this utility model, it also includes a shield top code and a receiving frame top code. The shield top code is set on the shield machine host, and the receiving frame top code is set on the receiving frame. The shield top code and the receiving frame top code are spaced apart front and back. The two ends of the translation cylinder are respectively connected to the shield top code and the receiving frame top code.

[0008] As a further improvement of this utility model, the pulley is mounted on the receiving frame, and the slide rail is mounted on the main body of the tunnel boring machine.

[0009] As a further improvement of this utility model, it also includes a connecting support and a pulley fixing rod, wherein the connecting support is fixed on the receiving frame, the pulley fixing rod is connected to the connecting support, and the pulley is connected to the pulley fixing rod.

[0010] As a further improvement of this utility model, the slide is arranged along the translational direction of the tunnel boring machine host.

[0011] As a further improvement of this utility model, the cross-section of the slide is an I-shaped structure, and the pulleys are respectively arranged on the left and right sides of the I-shaped structure.

[0012] As a further improvement of this utility model, it also includes a fixed support, which is fixed on the main body of the tunnel boring machine, and the slide rail is fixed on the fixed support.

[0013] The beneficial effects of this utility model are as follows: By using the lifting cylinder, the translation cylinder, the pulley and the slide rail, the alternating translation between the shield machine host and the receiving frame can be realized.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-3 As shown, a shield tunneling machine main body overall translation device includes a shield tunneling machine main body 1, a receiving frame 2, a lifting cylinder 3, a translation cylinder 4, a pulley 5, and a slide rail 6.

[0020] The tunnel boring machine host 1 can be detachably placed at the foremost position of the receiving frame 2.

[0021] The shield machine host 1 has a lifting base 11 welded and fixed on the left and right sides respectively. One end of the lifting cylinder 3 is connected to the bottom of the lifting base 11 of the shield machine host 1 by bolts, and the other end can be detached and rest against the ground.

[0022] The shield machine host 1 is welded and fixed with shield top code 12, and the receiving frame 2 is welded and fixed with receiving frame top code 21. The translation cylinder 4 is extended to its maximum stroke, and then the two ends of the translation cylinder 4 are connected to the shield top code 12 and the receiving frame top code 21 respectively by bolts and fixing pins.

[0023] A connecting support 22 is welded and fixed to the receiving frame 2. A pulley fixing rod 23 is connected to the connecting support 22, and the receiving frame 2 is connected to the pulley 5 through the pulley fixing rod 23. Fixed supports 13 are welded and fixed to the shield machine host 1 at intervals along its translational direction. The slide rail 6 is welded and fixed to the fixed supports 13, so that the slide rail 6 is set along the translational direction of the shield machine host 1. The cross-section of the slide rail 6 is an I-shaped structure, and the pulleys 5 are respectively set on the left and right sides of the I-shaped structure. A height difference is left between the pulleys 5 and the slide rail 6, so that the pulleys 5 and the slide rail 6 are separated. It should be noted that in other embodiments, the pulleys 5 can also be set on the shield machine host 1, while the slide rail 6 is set on the receiving frame 2.

[0024] In the above-mentioned device, the shield machine can be lifted by the lifting cylinder 3. When the shield machine host 1 is not lifted, the shield machine host 1 can be moved horizontally by the translation cylinder 4. When the shield machine host 1 is lifted, the pulley 5 is connected to the slide rail 6 to drive the receiving frame 2 to be lifted synchronously. At this time, the receiving frame 2 can be moved horizontally along the slide rail 6 by the translation cylinder 4.

[0025] The steps for using the above device are as follows:

[0026] 1. The shield machine host 1 is lifted to a certain height by the lifting cylinder 3. The height difference between the pulley 5 and the slide rail 6 is gradually reduced until the pulley 5 is just stuck on the slide rail 6. At this time, the shield machine host 1 will be lifted at the same time, and the receiving frame 2 will be lifted synchronously until the receiving frame 2 is lifted off the ground and is in a suspended and movable state.

[0027] 2. The translation cylinder 4 retracts, driving the receiving frame 2. The receiving frame 2 moves horizontally with the help of pulley 5 and slide rail 6 until the translation cylinder 4 retracts completely.

[0028] 3. The lifting cylinder 3 retracts, and after the shield machine main unit 1 and the receiving frame 2 descend to the ground, the lifting cylinder 3 continues to retract until the lower end of the lifting cylinder 3 leaves the ground.

[0029] 4. The translation cylinder 4 extends and, under the reaction force of the receiving frame 2, pushes the shield machine host 1 to translate until the translation cylinder 4 is fully extended.

[0030] 5. Repeat the above steps to complete the overall stepping and translation of the tunnel boring machine host 1.

[0031] The above-mentioned device enables the overall translation of the tunnel boring machine host 1, which features high safety performance, strong practicality, high translation efficiency, and wide application range. It can be applied to the overall translation of tunnel boring machine host 1 of different sizes. At the same time, compared with the current method of translating by laying steel plates, its cost is greatly reduced, which can effectively save costs.

[0032] The above-described embodiments are only for illustrative purposes and are not intended to limit the present invention in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present invention without departing from the scope of the technical features of the present invention shall still fall within the scope of the technical features of the present invention.
