[0001] The utility model belongs to the technical field of shield construction, and particularly relates to a novel shield whole machine translation device. Background Art

[0002] Shield construction is relatively mature, with the advantages of low labor intensity, high efficiency, high quality, safety and low impact on the external environment. It is widely used in the construction of underground pipelines and tracks. When the station construction is completed, it is an important work link for the shield machine to pass through the station and enter the next work area. In this process, translation technology is required to ensure that the quality machine can move smoothly to the next work area or reach the predetermined position.

Under the bracket, 10 Teflon slides are symmetrically distributed, and steel plates with a thickness of 16mm or more are laid on the station floor. At the same time, butter is applied to reduce the friction between objects so that the shield can move horizontally on the backfilled and laid steel plates. There are the following problems: 1. High costs in the early and late stages; 2. The Teflon slides are easy to fall off during construction; 3. The direction of travel is easy to deviate during the translation and jacking process; 4. The backfill cushion and steel plate laying accuracy requirements are high, and the construction is complicated. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to better understand the purpose, structure and function of the utility model, a new type of shield machine translation device of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1~Figure 4 As shown, a new type of shield machine translation device includes a force-bearing bracket 1 and a reaction frame 2 of a frame structure. A shield body 6 of a shield machine is placed on the force-bearing bracket 1, and translation tracks 5 are arranged on both sides of the lower side of the force-bearing bracket 1. A reinforcing steel plate 3 is arranged at the lower end of the force-bearing bracket 1 to contact the translation track 5. Anti-deviation blocks 4 are arranged on both sides of the translation track 5 of the reinforcing steel plate 3. The reaction frame 2 is arranged at the rear end of the force-bearing bracket 1 and abuts against the tail of the shield body 6 of the shield machine. A track clamp 7 is arranged at the rear of the reaction frame 2 for the translation track 5, and a translational pushing hydraulic jack 8 is arranged between the track clamp 7 and the reaction frame 2 to push the reaction frame 2.

[0018] In this embodiment, the load-bearing bracket 1 includes support frames 11 arranged in parallel, and the support frames 11 are connected by connecting beams 12. A plurality of support legs 13 extending along the radial direction of the shield machine are arranged at intervals on the support frames 11, and support I-beams 14 are arranged on the support legs 13 to contact the shield body 6 of the shield machine.

[0019] The reinforcing steel plate 3 strengthens and thickens the translation friction contact surface of the bottom of the force-bearing bracket 1, does not damage the overall structure of the force-bearing bracket 1 during translation, and can be easily replaced when it is severely worn. In this embodiment, four reinforcing steel plates 3 are provided, with a size of 600mm*400mm*50mm, respectively located at the four corners of the force-bearing bracket 1, and the front end of the reinforcing steel plate 3 needs to be sloped to avoid the situation of track jamming during translation.

[0020] After the bottom of the load-bearing bracket 1 is reinforced with a reinforcing steel plate 3, a small iron block made of a 3cm steel plate is used as an anti-deviation block 4, which is welded and fixed on both sides of the reserved track position at the bottom of the reinforcing steel plate 3 according to the spacing of the laid tracks to achieve the purpose of anti-deviation, making it a simple train wheel device. At least two pairs of anti-deviation blocks 4 are set on the front and back of each reinforcing steel plate 3.

[0021] A translation track 5 is arranged on each side below the force-bearing bracket 1 at the starting position, and the spacing is adjusted to be consistent with the spacing distance of the anti-deviation block 4. The backfill concrete surface elevation at the installation location of the translation track 5 is flush with the bottom surface of the translation track 5, and the other concrete surface elevations are not less than 70mm above the translation track 5.

[0022] The track clamp 7 adopts a 50T hydraulic track clamp, and the translational jacking hydraulic jack 8 adopts two 200T hydraulic jacks. The track clamp 7 is used to clamp the top of the translational track 5 laid at the bottom, so as to generate a forward reaction force for the translational jacking hydraulic jack 8 to push forward, so that the shield body 6 of the shield machine moves forward along the axis above the laid translational track 5.

[0023] During translation, the anti-deviation block 4 set at the bottom of the force-bearing bracket 1 after being reinforced with a reinforcing steel plate 3 is stuck above the translation track 5. When the force-bearing bracket 1 is lowered into the well, ensure that the anti-deviation block 4 welded at the four corners is completely engaged with the translation track 5 used for laying translation, so that it forms a simple train wheel. Then, the shield body 6 of the shield machine is assembled in sequence. After the assembly is completed, the reaction frame 2 is lowered into the well as a whole and located at the tail of the force-bearing bracket 1. Adjust its center deviation and vertical deviation to make it coincide with the center (design axis) of the shield body 6 of the shield machine. The installation and positioning are completed at one time to avoid secondary adjustment after translation to the starting position. Then, reinforcement welding is performed. After completion, the whole machine is translated with the shield body 6 of the shield machine. The translation track 5 is laid to fit the translation axis to achieve controllable direction. The tail cylinder reaction device adopts a track clamp 7, which is more convenient, simple to construct, safe and controllable.

[0024] This device was implemented in the shield starting shaft of Yingzeqiao West Station of Taiyuan Metro Line 1, which solved the problem of the shield machine moving 48 meters horizontally in the station for positioning before starting. Compared with the existing technology, the actual construction process has low investment cost, low construction cost, relatively convenient and easy to create construction conditions, and is safer and more stable. There are no construction obstacles such as faults during construction, which shortens the construction period, improves efficiency, and brings certain economic benefits.
