Description

Technical Field

[0001] This utility model relates to the technical field of underground continuous wall construction equipment, and in particular to a cutter box and TRD construction equipment. Background Technology

[0002] During the TRD (Traction Wall Method) construction process, as the depth of the diaphragm wall increases, the cutter head box needs to be configured into multiple interconnected sections according to the depth of the diaphragm wall.

[0003] In existing knife box connection structures, the upper and lower chain knife boxes are aligned and positioned by positioning pins and positioning holes on the upper and lower end faces of the two knife boxes, and are fastened together by multiple fastening bolts passing through the connection holes on the end faces of the upper and lower knife boxes. As the TRD construction depth increases, the chain knife boxes will generate a large shear force at the connection point between the knife boxes when moving laterally for construction. The lateral tensile force on the bolts increases, and the bolts are at risk of breaking. Bolt breakage can lead to chain knife breakage and chain detachment, affecting the stability of the knife box structure. It may even cause the knife boxes to separate and remain deep underground, seriously affecting the construction quality and progress, and increasing construction costs. Utility Model Content

[0004] The purpose of this invention is to provide a toolbox and TRD construction equipment that can effectively counteract the shearing force between guides and ensure construction quality.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The knife box includes:

[0007] The tool box segment is provided with multiple segments. The outer periphery of the upper end of the tool box segment is provided with a first connecting groove, and the outer periphery of the lower end is provided with a second connecting groove. In the vertical direction, when two tool box segments press against each other, the first connecting groove of one tool box segment can communicate with the second connecting groove of the other tool box segment to form a ring-shaped locking groove.

[0008] The splicing component is ring-shaped and can extend into the locking groove;

[0009] The first buffer member, when the splicing member extends into the locking groove, has one side that can press against the outer periphery of the splicing member, and the other side that can press against the joint of two adjacent blade box segments.

[0010] Preferably, a second buffer is also included. When the splicing member extends into the locking groove, one side of the second buffer can press against the inner circumference of the splicing member, and the other side can press against the joint of two adjacent blade box segments.

[0011] Preferably, the upper end face of the tool box segment is provided with a first splicing groove and the lower end face is provided with a second splicing groove. When two tool box segments press against each other, the first splicing groove of one tool box segment can communicate with the second splicing groove of the other tool box segment to form a buffer groove. The buffer groove is connected to the locking groove, and both the first buffer member and the second buffer member can extend into the buffer groove.

[0012] Preferably, one of the locking slots is configured with two locking slots.

[0013] Preferably, a locking element is also included, which is detachably disposed at the opening of the locking groove, and the locking element is configured to lock the splice in the locking groove.

[0014] Preferably, the locking member is provided with a pressing part, which can press against the first buffer member.

[0015] Preferably, the splicing component is in the shape of a ring.

[0016] Preferably, the first buffer member is provided with an arc-shaped first contact surface, which can be attached to the splicing member.

[0017] Preferably, multiple locking slots are spaced apart along the horizontal direction, and each locking slot is equipped with one splicing component and multiple first buffer components.

[0018] TRD construction equipment, configured to perform TRD operations, includes any of the aforementioned cutter boxes.

[0019] The beneficial effects of this utility model are:

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-5 As shown, this utility model provides a toolbox for TRD (Tracking, Detection, and Removal) construction operations. The toolbox includes toolbox segments 1, splicing components 2, and a first buffer component 3. Multiple toolbox segments 1 are provided. A first connecting groove 11 is formed on the outer periphery of the upper end of each toolbox segment 1, and a second connecting groove 12 is formed on the outer periphery of the lower end. In the vertical direction, when two toolbox segments 1 press against each other, the first connecting groove 11 of one toolbox segment 1 can communicate with the second connecting groove 12 of the other toolbox segment 1 to form a ring-shaped locking groove. The splicing component 2 is ring-shaped and can extend into the locking groove. When the splicing component 2 extends into the locking groove, one side of the first buffer component 3 can press against the outer periphery of the splicing component 2, and the other side can press against the joint between two adjacent toolbox segments 1.

[0037] The two adjacent tool box segments 1 press against each other, so that the first connecting groove 11 and the second connecting groove 12 can be connected to each other and spliced ​​into a locking groove. When the splicing piece 2 is inserted into the locking groove, the two adjacent tool box segments 1 are locked to each other. The operation is simple and convenient, and the structure is solid and reliable. The setting of the first buffer 3 can alleviate the shearing force on the splicing piece 2 in the horizontal direction and protect the splicing piece 2, thereby further improving the connection strength and durability of the two adjacent tool box segments 1.

[0038] For example, in this embodiment, the splice 2 is annular. This design prevents stress concentration on the splice 2 and improves structural durability.

[0039] For example, in this embodiment, the first buffer 3 is provided with an arc-shaped first contact surface, which can be attached to the splicing member 2. The above configuration can increase the contact area between the first buffer 3 and the splicing member 2, thereby increasing the friction between them.

[0040] More specifically, multiple locking slots are spaced horizontally, and each locking slot is equipped with a splicing component 2 and multiple first buffer components 3. This arrangement makes the force on the tool box segment 1 more balanced and its stability higher.

[0041] For example, in this embodiment, seven locking slots are provided at intervals on both sides of the tool box segment 1 along the vertical direction. In other embodiments, the number of locking slots can be determined according to actual needs, and no specific limitation is made here.

[0042] Specifically, the tool box also includes a second buffer 4. When the splice 2 extends into the locking groove, one side of the second buffer 4 can press against the inner circumference of the splice 2, and the other side can press against the joint of two adjacent tool box segments 1. The above-mentioned second buffer 4 can further buffer the shear force on the splice 2 in the horizontal direction and protect the splice 2.

[0043] Preferably, in this embodiment, the second buffer 4 is provided with an arc-shaped second contact surface, which can fit against the inner circumference of the splicing member 2. This arrangement increases the contact area between the second buffer 4 and the splicing member 2, thereby increasing the friction between them.

[0044] More specifically, the upper end face of the tool box segment 1 is provided with a first splicing groove 13, and the lower end face is provided with a second splicing groove 14. When two tool box segments 1 press against each other, the first splicing groove 13 of one tool box segment 1 can communicate with the second splicing groove 14 of the other tool box segment 1 to form a buffer groove. The buffer groove is connected to the locking groove, and the first buffer member 3 and the second buffer member 4 can both extend into the corresponding buffer groove. The above configuration and the above buffer groove configuration can increase the contact area between the first buffer member 3 and / or the second buffer member 4 and the outer surface of the tool box segment 1, thereby improving the structural stability.

[0045] More specifically, each locking slot is configured with two locking slots. This configuration further improves structural stability.

[0046] Specifically, the toolbox also includes a locking element 5, which is detachably disposed at the opening of the locking groove. The locking element 5 is configured to lock the splice 2 in the locking groove. The locking element 5 prevents the splice 2 from sliding out of the locking groove during operation.

[0047] More specifically, the locking member 5 is provided with a pressing part 51, which can press against the first buffer member 3. The aforementioned pressing part 51 can prevent the first buffer member 3 from sliding out of the buffer groove during operation.

[0048] Preferably, in this embodiment, the locking member 5 is cross-shaped, so that the pressing part 51 presses against the first buffer member 3 while also pressing against the second buffer member 4.

[0049] For example, in this embodiment, the locking member 5 is connected to the tool box section 1 by a bolt structure to achieve a detachable connection.

[0050] This utility model also provides a TRD construction device configured to perform TRD operations, which includes the aforementioned toolbox. It is understood that this TRD construction device possesses all the beneficial effects of the aforementioned toolbox, which will not be elaborated upon here.

[0051] It is understandable that the number and height of the cutter box segment 1 can be determined according to the actual needs of the construction operation, and no specific limit is made here.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
