Description

Technical Field

[0001] This utility model relates to the field of construction technology for full-face tunnel boring machines for vertical shafts, and in particular to a support shoe structure. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Chinese invention patent application number CN202310466159.1 discloses a suspension system and method for a hanging platform used in the construction of a deep vertical shaft full-face tunneling machine. It discloses a hanging platform with a hydraulic support shoe, which is responsible for stabilizing and tightening the platform. The hydraulic support shoe can also control the thrust and stroke of the hydraulic support shoe to correct the deviation of the hanging platform.

[0004] However, because the support shoes bear the dynamic load of the hoisting platform (for example, when the formwork is suspended at the bottom of the hoisting platform, the load of the concrete is overcome by the friction generated by the support shoes tightening the well wall during concrete pouring, as well as the dynamic load of transportation and drainage, which is also borne by the support shoes), the support shoes not only need to have a large supporting force, but also need to have shear resistance performance requirements; however, the shear resistance performance of the hydraulic cylinder telescopic rod is relatively weak, and excessive shear force can easily cause damage to the hydraulic cylinder, affecting normal construction. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a boot support structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a boot support structure, comprising:

[0007] Mounting base;

[0008] The telescopic component has one end rotatably mounted on one side of the mounting base;

[0009] A support rod, one end of which is rotatably mounted on the opposite side of the mounting base relative to the telescopic component, and the other end of the support rod is rotatably connected to the telescopic component. The support rod, the telescopic component, and the mounting base form a triangular structure.

[0010] An abutment plate is set on one side of the corresponding well wall of the support rod and located in the middle of the support rod. A hinged ball head is provided at the position of the abutment plate of the support rod, and the ball head is hinged to the ball of the abutment plate.

[0011] Furthermore, the support rod is a triangular plate structure, and the abutment plate is located on one side of the corresponding well wall of the triangular plate.

[0012] Furthermore, the abutment plate is available in various sizes and is detachably connected to the hinge ball head.

[0013] Furthermore, one side of the abutment plate corresponding to the well wall has the same arcuate surface as the inner wall of the well wall, for fitting against the well wall.

[0014] According to the claim or the support structure, the support rod, the telescopic component and the mounting base are respectively provided with a rotating shaft at the three rotating endpoints of the triangle formed by them, so that two adjacent components can rotate relative to each other, and the rotating shaft is fixedly connected to one of the components respectively.

[0015] It also includes a locking device, which is located at at least one rotating shaft to prevent the rotating shaft from rotating relative to another component.

[0016] Furthermore, the locking device includes a fixing plate fixedly mounted on the corresponding rotating shaft. One side of the fixing plate extends toward another component that is not fixed to the rotating shaft. The component has a screw hole at the position corresponding to the fixing plate, and the fixing plate has a through hole at the position corresponding to the screw hole. The included angle between two adjacent components is locked by passing a bolt through the through hole and the screw hole.

[0017] Furthermore, the support rod of the triangular plate structure is hollow inside, and a first reinforcing plate is provided at the corresponding hinge ball head position inside the support rod. The first reinforcing plate is connected to three sides of the triangular plate structure.

[0018] Furthermore, it also includes a second reinforcing plate, which is disposed inside the triangular plate structure and is parallel to the side of the triangular plate structure away from the abutment plate. It is connected to the other two sides of the triangular plate structure and is fixedly connected to the first reinforcing plate.

[0019] Furthermore, the triangular plate structure consists of three sides and two side plates. The second reinforcing plate is provided with protrusions at the positions of the corresponding two side plates, and the side plates are provided with through grooves at the positions of the corresponding protrusions, so that the protrusions can be inserted into the through grooves.

[0020] A shaft sinking platform for a full-face tunnel boring machine, wherein multiple support shoe structures as described above are installed around the bottom of the platform.

[0021] The beneficial effects of this utility model are reflected in:

[0022] In this invention, when the abutment plate contacts the well wall, the reaction force of the abutment plate is first transmitted to the support rod, and then to the mounting base and the telescopic component. The direction of the force transmitted to the telescopic component is along the axis of the telescopic component, so the shear force on the telescopic component is small, greatly reducing the probability of damage to the telescopic component. At the same time, this structure can also amplify the thrust output by the telescopic component, achieving multiple benefits. Furthermore, by using a ball joint connection to connect the abutment plate and the support rod, a perfect fit between the abutment plate and the well wall is achieved, which can reduce the damage of the support shoe to the well wall.

[0029] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figure 1-4 This utility model discloses a boot support structure, comprising:

[0031] Mounting base 1;

[0032] Telescopic component 2, one end of which is rotatably mounted on one side of mounting base 1;

[0033] The support rod 3 has one end rotatably mounted on the other side of the mounting base 1 opposite to the telescopic component 2, and the other end of the support rod 3 is rotatably connected to the telescopic component 2. The support rod 3, the telescopic component 2 and the mounting base 1 form a triangular structure.

[0034] The abutment plate 4 is set on one side of the corresponding well wall of the support rod 3 and is located in the middle of the support rod 3. The support rod 3 is provided with a hinge ball head 31 at the position of the abutment plate 4, and is ball-hinged with the abutment plate 4 through the hinge ball head 31.

[0035] In practice, by setting the abutment plate 4 on one side of the corresponding well wall of the support rod 3, when the telescopic component 2 extends or retracts, the abutment plate 4 contacts the well wall under the action of the support rod 3. The reaction force of the abutment plate 4 is first transmitted to the support rod 3, and then to the mounting base 1 and the telescopic component 2. The direction of the force transmitted to the telescopic component 2 is along the axis of the telescopic component 2. Therefore, the shear force on the telescopic component 2 is small, which greatly reduces the probability of damage to the telescopic component 2. At the same time, this structure can also amplify the thrust output by the telescopic component 2, achieving multiple benefits in one fell swoop.

[0036] Furthermore, this application uses a ball joint connection to connect the abutment plate 4 to the support rod 3, achieving a perfect fit between the abutment plate 4 and the well wall, which can reduce the damage of the support shoe to the well wall.

[0037] Preferably, the telescopic component 2 is a hydraulic telescopic rod, but electric or pneumatic telescopic rods from the prior art can also be used.

[0038] In one embodiment, the support rod 3 is a triangular plate structure, and the abutment plate 4 is located on one side of the corresponding well wall of the triangular plate. This design can further reduce the extension stroke of the telescopic component 2.

[0039] In one embodiment, the abutment plate 4 is provided in various sizes and is detachably connected to the hinge ball head 31. This design allows for the replacement of different abutment plates 4 as needed, ensuring that the area of ​​the abutment plate 4 varies according to the tensioning force of the support shoe, thus guaranteeing that the contact pressure on the well wall does not exceed 2 MPa, in order to avoid damaging the well wall that has just been constructed.

[0040] In one embodiment, one side of the abutment plate 4 corresponding to the well wall has the same arcuate surface as the inner wall of the well wall, for better fit with the well wall.

[0041] In one embodiment, a rotating shaft 5 is provided at each of the three rotating endpoints of the triangle formed by the support rod 3, the telescopic component 2, and the mounting base 1, so that two adjacent components can rotate relative to each other, and the rotating shaft 5 is fixedly connected to one of the components respectively.

[0042] It also includes a locking device 6, which is disposed at at least one rotating shaft 5 to prevent the rotating shaft 5 from rotating relative to another component. In this design, the locking device 6 prevents another component that is not fixed to the rotating shaft 5 from rotating relative to the rotating shaft 5, thus fixing one corner of the triangle, which facilitates the transportation and installation of the support boot.

[0043] In one embodiment, the locking device 6 includes a fixing plate 61 fixedly mounted on the corresponding rotating shaft 5. One side of the fixing plate 61 extends toward another component that is not fixed to the rotating shaft 5, and the component has a screw hole 62 at the position corresponding to the fixing plate 61. The fixing plate 61 has a through hole at the position corresponding to the screw hole 62. The included angle between two adjacent components is locked by passing a bolt 63 through the through hole and the screw hole 62.

[0044] In one embodiment, the support rod 3 of the triangular plate structure is hollow inside, and a first reinforcing plate 32 is provided at the position of the corresponding hinge ball head 31 inside the support rod 3. The first reinforcing plate 32 is connected to the three sides of the triangular plate structure. This design reduces the weight of the support rod 3 while improving the mechanical properties at the hinge ball head 31.

[0045] In one embodiment, a second reinforcing plate 33 is also included. This second reinforcing plate 33 is disposed inside the triangular plate structure and is parallel to the side of the triangular plate structure away from the abutment plate 4. It is connected to the other two sides of the triangular plate structure and is fixedly connected to the first reinforcing plate 32. This design can further ensure the mechanical properties of the triangular plate structure, enabling the strut 3 to withstand greater forces.

[0046] It should be noted that the first reinforcing plate 32 can pass through the second reinforcing plate 33 and be fixedly welded to the second reinforcing plate 33 while being welded to the side of the triangular plate structure away from the abutting plate 4; of course, with the second reinforcing plate 33, the first reinforcing plate 32 can also be directly fixedly connected to the second reinforcing plate 33 and no longer connected to the side of the triangular plate structure away from the abutting plate 4.

[0047] In one embodiment, the triangular plate structure consists of three sides and two side plates 34. The second reinforcing plate 33 is provided with protrusions 331 at the positions corresponding to the two side plates 34, and the side plate 34 is provided with through grooves 341 at the positions corresponding to the protrusions 331, and the protrusions 331 can be inserted into the through grooves 341.

[0048] In practice, when processing the triangular plate structure, it is necessary to first weld the three sides of the triangular plate structure and the internal first reinforcing plate 32 and second reinforcing plate 33, and finally install the two side plates 34. When installing the last side plate 34, it is difficult for the side plate 34 to be fixed with the second reinforcing plate 33. Therefore, the form of the protrusion 331 and the slot 341 can not only position the side plate 34 through the protrusion 331, but also facilitate the welding and fixing of the protrusion 331 and the side plate 34 from the outside. Furthermore, even if welding is not performed or the weld is detached later, under the limitation of the slot 341, the second reinforcing plate 33 can still transmit the force to the side plate 34 through the protrusion 331, ensuring the mechanical performance of the strut 3.

[0049] In one embodiment, a third reinforcing plate 35 is fixed to the side of the side plate 34 away from the abutment plate 4. This is used to further reinforce the side plate 34.

[0050] This utility model also discloses a shaft sinking platform for a full-face tunnel boring machine. Multiple support shoes are evenly distributed around the bottom of the platform, and the support shoes are installed at the bottom of the platform via a mounting base 1.

[0051] The suspended platform has two or more layers, with four sets of support shoes evenly distributed around the perimeter of each layer. These support shoes are driven by hydraulic oil, and the hydraulic stations that output the hydraulic oil are located on the corresponding sections of the suspended platform.

[0052] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0053] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0054] Additionally, "multiple" refers to two or more.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
