Description

Technical Field

[0001] This utility model relates to the field of shield tunneling translation technology, and in particular to a portable shield tunneling translation tool. Background Technology

[0002] In subway tunnel construction, depending on the specific subway plan, sometimes after the left-line tunnel boring machine (TBM) has successfully completed its breakthrough, it will be used to proceed to the right-line of the next section (and vice versa). The TBM needs to be moved laterally within the station to reach the next starting position. Alternatively, due to heavy surface traffic, one side of the station roof may be closed in advance, requiring the TBM to be moved to the other side of the hoisting opening for dismantling after receiving the machine; this also necessitates lateral movement. The overall lateral movement of the TBM is a common working condition.

[0003] Currently, the traditional method of lateral translation for tunnel boring machine (TBM) crossing mainly involves installing steel plates or rails on the foundation (base plate) under the TBM bracket. Hinged clamping walls are installed on both sides of the bracket, with the upper end of the clamping wall hinged to one end of a connecting rod, and the other end of the connecting rod hinged to the telescopic end of the clamping cylinder. The hydraulic system is connected to the propulsion cylinder and the clamping cylinder, and the reciprocating cycle controlled by the cylinders completes the TBM translation. Current testing presents challenges.

[0004] The aforementioned translation operation method involves many influencing factors and is easily affected by the construction environment, thus having limitations. If there is no main sidewall or other structure to provide reaction force, a reaction frame must be constructed separately, which seriously affects the construction period. At the same time, it also requires a large investment of manpower, material resources, and financial resources, increasing construction costs. Therefore, a portable shield tunneling translation tool is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable shield tunneling translation tool, which aims to improve the problem that the existing technology usually requires the construction of a reaction frame during lateral translation, which increases the construction cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable shield tunneling machine translation tooling includes a translation tooling and a shield tunneling machine body. A translation tooling stiffener is fixedly connected to the side of the translation tooling, and a fixing component is installed on the side of the translation tooling stiffener. A lifting component is installed on the side of the shield tunneling machine body. The fixing component includes a tooling male head, a reaction seat female head is slidably connected to the side of the tooling male head, and a tooling reaction seat is fixedly connected to the top of the reaction seat female head.

[0008] As a further description of the above technical solution:

[0009] The lifting assembly includes a vertical jack, and a bracket is fixedly connected to the side of the tunnel boring machine body. The output end of the vertical jack is fixedly connected to the bottom of the bracket.

[0010] As a further description of the above technical solution:

[0011] The top of the translation tool is slidably connected to a bracket, and the top of the bracket is fixedly connected to a fixing block;

[0012] As a further description of the above technical solution:

[0013] A horizontal jack is fixedly connected to the side of the tooling reaction seat, and the output end of the horizontal jack is fixedly connected to the side of the bracket.

[0014] As a further description of the above technical solution:

[0015] The male tool head has a pin hole 1 inside, and the female reaction seat head has a pin hole 2 inside. The pin hole 2 and the pin hole 1 are horizontally aligned.

[0016] As a further description of the above technical solution:

[0017] The male tool head is internally slidably connected with a pin, and the female reaction seat head is internally slidably connected with a pin;

[0018] As a further description of the above technical solution:

[0019] The brackets and vertical jacks are specifically configured in four sets, and all four sets of brackets and vertical jacks are installed on both sides of the tunnel boring machine body.

[0020] As a further description of the above technical solution:

[0021] The translation fixture specifically uses six H-beams, with two of them forming a set and being welded together.

[0022] This utility model has the following beneficial effects:

[0023] 1. Similar to large-scale shield tunneling machine translation equipment, this portable device helps to achieve the translation and adjustment of the shield machine, ensuring tunnel accuracy and construction safety. By reducing the need for construction reaction frames or borrowing the main structure of the site, it also reduces the impact of construction on existing structures, resulting in higher safety and reliability.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a portable shield tunneling machine translation fixture, comprising a translation fixture 6 and a shield machine body 1. A translation fixture stiffener 601 is fixedly connected to the side of the translation fixture 6, increasing its rigidity. A fixing component is installed on the side of the translation fixture stiffener 601, and a lifting component is installed on the side of the shield machine body 1. The fixing component includes a male fixture head 8, a female reaction seat head 10 slidably connected to the side of the male fixture head 8, a fixture reaction seat 7 fixedly connected to the top of the female reaction seat head 10, and a horizontal jack 5 fixedly connected to the side of the fixture reaction seat 7. The output end of the horizontal jack 5 is fixedly connected to the side of a bracket 4, and the horizontal jack 5 operates by means of the horizontal jack 5. At this time, one end of the horizontal jack 5 is connected to the fixture... The reaction seat 7 contacts the output end and the side of the bracket 4. The horizontal jack 5 is extended and retracted to realize the lateral translation of the tunnel boring machine. The operation is convenient, reduces the requirements for the construction site, and improves the practicality of the device. The tooling reaction seat 7 is used to resist the horizontal reaction force of the horizontal jack 5. The tooling male head 8 has a pin hole 11 inside, and the reaction seat female head 10 has a pin hole 13 inside. The pin hole 13 is horizontally aligned with the pin hole 11. The tooling male head 8 and the reaction seat female head 10 are slidably connected with a pin 9 inside. By inserting the reaction seat female head 10 into the tooling male head 8, the pin 9 is inserted into the pin hole. This allows for the installation and disassembly of the tooling male head 8 and the reaction seat female head 10, which is convenient for assembly and improves the convenience of the device.

[0034] Reference Figure 1 The lifting assembly includes a vertical jack 3. A bracket 2 is fixedly connected to the side of the tunnel boring machine body 1. The output end of the vertical jack 3 is fixedly connected to the bottom of the bracket 2. When the tunnel boring machine body 1 is moved laterally, when the horizontal jack 5 has reached its limit, the vertical jack 3 works under the action of the bracket 2 to lift the tunnel boring machine body 1, thus facilitating the lateral movement of the translation tool 6. After the translation tool 6 reaches the designated position, the vertical jack 3 is retracted, and the next cycle of translation begins. This ensures that the tunnel boring machine body 1 is not affected by the construction environment during lateral movement, reducing construction costs. There are four sets of brackets 2 and vertical jacks 3, all of which are installed on both sides of the tunnel boring machine body 1 to facilitate the lifting of the tunnel boring machine body 1.

[0035] Reference Figure 2 and Figure 4 The top of the translation fixture 6 is slidably connected to a bracket 4, and the top of the bracket 4 is fixedly connected to a fixing block 12, which supports and fixes the shield machine body 1, improving the stability of the shield machine body 1 when it moves. The translation fixture 6 is made of six H-beams, two of which are welded together as a group. Since the shield machine is heavy, this ensures that the translation fixture 6 does not deform when the shield machine moves on it.

[0036] Working principle: First, the horizontal jack 5 is installed on top of the translation fixture 6. One end of the horizontal jack 5 contacts the top of the bracket 4, and the other end contacts the reaction seat 7 of the fixture. The horizontal jack 5 is then extended and retracted to achieve lateral translation of the tunnel boring machine. If the horizontal jack 5 has reached its limit, the vertical jack 3 is used to lift the bracket 2, causing the bracket 4 and the tunnel boring machine to rise together. When the bracket 4 leaves the translation fixture 6, the lifting stops. At this point, the translation fixture 6 is moved laterally. After reaching the designated position, the vertical jack 3 is retracted, thus starting the next cycle of translation. This method enables lateral translation of the tunnel boring machine, is easy to operate, and greatly reduces dependence on the construction site.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
