Description

Technical Field

[0001] This utility model relates to the field of shield tail brush assembly technology, and in particular to an automatic shield tail brush assembly device. Background Technology

[0002] A tunnel boring machine (TBM), also known as a shield tunneling machine, is a specialized engineering machine for tunnel excavation. Modern TBMs integrate optics, mechanics, electronics, hydraulics, sensing, and information technology, possessing functions such as excavating and cutting soil and rock, transporting excavated material, assembling tunnel lining, and measuring and guiding. They involve multiple disciplines including geology, civil engineering, mechanical engineering, mechanics, hydraulics, electrical engineering, control, and surveying. Furthermore, they require customized design and manufacturing based on different geological conditions, demanding extremely high reliability. TBMs are widely used in tunnel projects for subways, railways, highways, municipal works, and hydropower projects.

[0003] The tail brush is a component that prevents mud and water from seeping into the tail of the tunnel boring machine (TBM). There are generally two types: steel plate brushes and steel wire brushes. The steel wire brush is a mesh-like tail brush with a main sealing component formed by many folded, wavy steel wires. After grease is injected into the steel wire brush, the grease is absorbed into the wire network. During operation, the grease creates an oil seal between the steel wire brush and the inner wall of the TBM, thus preventing liquid from entering the TBM. A composite tail brush is a type of tail brush that combines the advantages of both steel wire brushes and steel plate brushes. However, a highly corrosive natural electrolyte exists, and oceans cover approximately 71% of the Earth's surface.

[0004] The existing technology, CN202121724289.3, describes a shield tail brush assembly machine that can prevent expansion before riveting. In the existing technology, after the shield tail brush is manually placed and assembled, the two ends of the wire clip need to be hammered again to press the two sides of the wire clip together to fix the internal steel wire. The production time is relatively long and the efficiency is low. In addition, the manual handling of the steel wire requires a certain amount of time.

[0005] Therefore, it is necessary to design an automatic assembly device for the tail brush to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an automatic assembly device for shield tail brushes, so as to overcome the above-mentioned shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An automatic shield tail brush assembly device includes an equipment platform, characterized in that: it further includes a pressing module disposed on the equipment platform, a coarse steel bar feeding module used to assemble the pressing module, and an assembly module disposed within the equipment platform. A pressing groove for pressing is provided on the equipment platform. The assembly module includes a mounting base, a pressing fixing block disposed on the mounting base, a pressing moving block that is installed in conjunction with the pressing fixing block and driven by a side pressing cylinder, an installation groove formed between the pressing moving block and the pressing fixing block, an end pressing cylinder disposed on one side of the pressing fixing block, and end pressing blocks driven by the end pressing cylinder and disposed at both ends of the installation groove opening.

[0010] Preferably, the front limit module and the rear limit module of the steel wire have the same structure and are respectively placed at both ends of the limit plate or the equipment platform. Each module includes a slide rail arranged parallel to each other on the limit plate, a baffle mounted on the slide rail by a slider, and a locking assembly for limiting and fixing the slider. The baffle is placed between the two limit plates.

[0011] Preferably, the pressing module includes a pressing bracket, a coarse steel bar picking pressing block disposed in the middle of the pressing bracket, a pressing cylinder for driving the coarse steel bar picking pressing block, steel wire limiting blocks disposed on both sides of the coarse steel bar picking pressing block, and a driving cylinder for driving the steel wire limiting blocks to move up and down.

[0018] Reference Figures 1 to 2 An automatic assembly device for shield tail brushes includes an equipment platform 1, a pressing module 2 set on the equipment platform, a coarse steel bar feeding module 3 used to assemble the pressing module, and an assembly module 4 placed in the equipment platform.

[0019] A pressing groove 11 for mating and pressing is provided on the equipment platform;

[0020] In order to enable the placement of steel wires of different sizes, a limiting component is provided on the equipment platform; the limiting component includes limiting plates 12 respectively placed on both sides of the pressing groove 11, a front limiting module 13 for steel wires set at one end of the equipment platform, and a rear limiting module 14 for steel wires set at the other end of the equipment platform.

[0021] The front and rear limiting modules of the steel wire have the same structure and are respectively placed at both ends of the limiting plate or the equipment platform. Each module includes a slide rail arranged parallel to each other on the limiting plate, a baffle mounted on the slide rail by a slider, and a locking assembly that limits and fixes the slider. The baffle is placed between the two limiting plates. By moving the baffle of the front limiting module, the position of the front end of the steel wire is limited. After the steel wire is laid between the limiting plates, one end is held against the baffle. The rear limiting module moves the baffle, and the baffle contacts the rear end of the steel wire, thereby bringing the steel wire together and limiting the rear end of the steel wire, thus completing the placement of the steel wire to be assembled.

[0022] The coarse steel bar feeding module 3 transmits coarse steel bars in groups to cooperate with the pressing module 2 for picking up and pressing. Specifically, it can be a combination of a vibratory plate and a conveyor belt structure. The coarse steel bars are driven to the bottom of the pressing module 2 for feeding through a telescopic mechanism.

[0023] The pressing module 2 includes a pressing bracket 21, a coarse steel bar picking pressing block 22 disposed in the middle of the pressing bracket, a pressing cylinder 23 for driving the coarse steel bar picking pressing block, wire limiting blocks 24 respectively disposed on both sides of the coarse steel bar picking pressing block, and a driving cylinder 25 for driving the wire limiting blocks to move up and down. In order to adsorb and clamp the coarse steel bar, a contour groove is provided at the bottom of the coarse steel bar picking pressing block, and an adsorption hole is provided in the contour groove. An external vacuum adsorption device is connected to the block. The vacuum adsorption device provides adsorption force to the adsorption hole. The pressing cylinder drives the coarse steel bar picking pressing block to move down and stick to the coarse steel bar. The coarse steel bar is adsorbed by the adsorption force.

[0024] The assembly module 4 includes a mounting base 41, a pressing and fixing block 42 disposed on the mounting base, a pressing and moving block 44 that is driven by a side pressing cylinder 43 to be installed in conjunction with the pressing and fixing block, an installation groove 45 formed between the pressing and moving block and the pressing and fixing block, an end pressing cylinder 46 disposed on one side of the pressing and fixing block, and an end pressing block 47 that is driven by the end pressing cylinder and disposed at both ends of the installation groove.

[0025] An installation groove is provided between the pressing moving block and the pressing fixing block, and a wire clip is laid in the installation groove; the pressing groove is connected to the installation groove and is used to place the wire clip for pressing.

[0026] To save space, a connecting rod assembly 48 is provided between the end pressing cylinder and the end pressing block. The connecting rod assembly converts the horizontal force into a vertical force, thereby driving the end pressing block to press the two ends of the slot, thus achieving the pressing of the two ends of the wire clip. Specifically, the connecting rod assembly 48 includes a mounting block driven by the end pressing cylinder, a first connecting rod that is respectively set on both sides of the mounting block and arranged outward in a figure-eight shape via a rotating shaft, a second connecting rod that is connected to the first connecting rod via a rotating shaft, and an end pressing block 47 that is connected to the second connecting rod via a rotating shaft. The end pressing block 47 is respectively set corresponding to the slots at both ends of the mounting groove, and a stop block 49 is also provided on the side to limit its movement.

[0027] In order to limit the direction of movement of the end pressing block, a stop 49 is also provided on the mounting base to limit the direction of movement of the end pressing block.

[0028] In this implementation, the wire clip is first drilled into the pressing groove 11 (i.e., the installation groove 45). Then, the steel wire to be pressed is laid on the equipment platform between the limiting plates 12. The position of the steel wire is then adjusted by the front and rear limiting modules. After adjustment, the equipment is started. The coarse steel bar feeding module 3 moves the coarse steel wire to the bottom of the coarse steel bar picking and pressing block of the pressing module. The coarse steel wire is then attracted to the bottom of the coarse steel bar picking and pressing block 22 through the suction holes. Then, the steel wire limiting blocks on both sides are driven downward by the driving cylinder to press down the two ends of the steel wire. The pressing cylinder then moves downward. The moving cylinder continuously moves the thick steel wire downwards and presses it into the corresponding pressing groove 11. At the same time, it enters the installation groove and places the thick steel wire in the wire clip, completing the initial pressing. At this time, the side pressing cylinder drives the pressing moving block 44 to approach the pressing fixing block 42, pressing and fixing the steel wires on both sides of the wire clip. The end pressing cylinder drives the connecting rod assembly 48 to drive the end pressing blocks 47 at both ends of the wire clip to press and fix the two ends of the wire clip. Thus, both sides and ends of the wire clip are pressed and fixed, ensuring that the internal steel wire and thick steel wire are placed inside the wire clip, and the wire clip is assembled in one press.

[0029] The advantages of this utility model are that the technical solution sets a limiting component on the equipment platform to quickly limit and adjust the steel wire to be pressed, preventing the front and rear lengths of the steel wire from being inconsistent and affecting the pressing efficiency. In addition, it can be adjusted according to the pressing size. Furthermore, a connecting rod component is set to cooperate with the pressing and fixing of the two ends of the wire clip, eliminating the need for manual additional fixing, saving time, and completing the assembly in one go.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
