Description

Technical Field

[0001] This utility model relates to the field of tunneling machine technology, specifically to a tunneling machine chain baffle. Background Technology

[0002] A tunneling machine (TBM) is a piece of equipment used for excavating underground tunnels, mines, or other underground projects. Its core functions include cutting, loading and transporting, self-propelled movement, and dust suppression. It mainly consists of a traveling mechanism, a working mechanism, a loading mechanism, and a transfer mechanism. As the traveling mechanism advances, the cutting head in the working mechanism continuously breaks up the rock and transports the broken rock away. The chain and tracks drive the TBM to move, and chain guards protect the chain.

[0003] The conveying mechanism includes a chain, sprockets, and chain plates. The chain and chain plates work together, with the chain plates driving the chain and thus rotating the chain plates. However, poor meshing between the sprockets and chain can cause chain skipping or derailment, affecting the normal operation of the tunneling machine. Therefore, those skilled in the art have provided a tunneling machine chain baffle to solve the problems mentioned in the background section. Utility Model Content

[0004] To solve the above technical problems, this utility model provides a tunneling machine chain baffle, including a baffle body, on which multiple positioning mechanisms are installed. Each positioning mechanism includes a mounting base, on which a mounting rod is horizontally mounted. A connecting rod is mounted at one end of the mounting rod, and a rotating sleeve is mounted on both the connecting rod and the mounting base.

[0005] A protective mechanism is installed on one side of the baffle body. The protective mechanism includes a fixed groove, one side of which is fixedly connected to the baffle body. Fixed rods are fixedly connected to both ends of the fixed groove. Movable grooves are slidably connected to the fixed rods. A protective plate is installed between the movable groove and the fixed groove.

[0006] Preferably, the baffle body is equipped with multiple connecting plates, which are located between the positioning mechanisms.

[0007] Preferably, the positioning mechanism is located on the upper and lower sides of the baffle body.

[0008] Preferably, the other end of the mounting rod is fixedly connected to a threaded rod, and an internal threaded sleeve is rotatably connected to one side of the baffle body. The internal threaded sleeve is located on one side of the threaded rod, and one end of the threaded rod is screwed into the internal threaded sleeve.

[0009] Preferably, one end of the internal threaded sleeve has a regular hexagonal cross-section.

[0010] Preferably, a spring is provided between the upper end of the fixed rod and the movable groove.

[0011] Preferably, the protective plate includes a raised back, the protective plate is made of elastic material, the upper end of the protective plate passes through the movable groove, and limit blocks are fixedly connected to both sides of the protective plate, with the limit blocks located below the movable groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model is designed with a positioning mechanism, which can limit the chain plate and the chain, prevent the chain from disengaging from the sprocket, and improve the stability of the chain operation.

[0014] 2. This utility model is designed with a protective mechanism. When the protective plate is squeezed and deformed, the external impact force is buffered. It is elastically connected to the fixed rod through the movable groove. After the protective plate is deformed, the movable groove moves upward, which can further buffer the impact and improve the pressure resistance. After the movable groove moves upward, the protective plate can be removed for easy replacement of the damaged protective plate. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4This embodiment provides a tunneling machine chain baffle, including a baffle body 1. Multiple positioning mechanisms 3 are installed on the baffle body 1. Each positioning mechanism 3 includes a mounting base 31. A mounting rod 32 is horizontally mounted on the mounting base 31. A connecting rod 33 is mounted on one end of the mounting rod 32. A rotating sleeve 34 is mounted on both the connecting rod 33 and the mounting base 31. The rotating sleeve 34 is located on both sides of the chain plate, thereby restricting the left and right displacement of the chain and preventing the chain from disengaging from the sprocket.

[0023] A protective mechanism 4 is installed on one side of the baffle body 1. The protective mechanism 4 includes a fixed groove 41, one side of which is fixedly connected to the baffle body 1. Fixed rods 42 are fixedly connected to both ends of the fixed groove 41. A movable groove 43 is slidably connected to the fixed rods 42. A protective plate 45 is installed between the movable groove 43 and the fixed groove 41. During installation, the movable groove 43 is moved upward, and the protective plate 45 is placed inside the movable groove 43. Then, the movable groove 43 is moved downward so that the upper end of the protective plate 45 passes through the top of the movable groove 43. The chain is protected by the baffle body 1. The protective plate 45 forms another layer of protection on one side of the baffle body 1, improving the protective performance of the baffle body 1. After the movable groove 43 is moved upward, the protective plate 45 can be removed and replaced. If a single protective plate 45 is damaged, it can be quickly replaced.

[0024] In a further embodiment, see Figure 1 The baffle body 1 is equipped with multiple connecting plates 2, which are located between the positioning mechanisms 3. The connecting plates 2 can connect the baffle body 1 to the tunneling machine body, thereby providing effective protection for the traveling mechanism.

[0025] In a further embodiment, see Figure 1 The positioning mechanism 3 is located on the upper and lower sides of the baffle body 1. The positioning mechanism 3 limits the upper and lower areas of the circular moving chain plate (the two ends of the lower chain plate do not contact the ground, so the chain plate in contact with the ground is limited and is not easy to deviate), thereby ensuring the overall transportation stability.

[0026] In a further embodiment, see Figures 1-2 The other end of the mounting rod 32 is fixedly connected to a threaded rod 35, and an internal threaded sleeve 36 is rotatably connected to one side of the baffle body 1. The internal threaded sleeve 36 is located on one side of the threaded rod 35, and one end of the threaded rod 35 is screwed into the internal threaded sleeve 36.

[0027] By rotating the internal threaded sleeve 36, the length of the mounting rod 32 inserted into the mounting base 31 can be changed, thereby making the mounting rod 32 movable. This allows the non-rotatable part of the mounting rod 32 to disengage from the mounting base 31 (the cylindrical threaded rod 35 moves into the through hole of the mounting base 31). The mounting rod 32 can rotate so that one end of the rotating sleeve 34 can be horizontal, allowing it to pass over the chain plate. When the connecting rod 33 moves to the other side of the chain plate, rotating the mounting rod 32 again will make the rotating sleeve 34 vertically positioned on one side of the chain plate, thereby limiting the movement of both sides of the chain plate.

[0028] In a further embodiment, see Figure 2 The internal threaded sleeve 36 has a regular hexagonal cross-section at one end. Because one end has a regular hexagonal cross-section, the internal threaded sleeve 36 can be rotated using common tools, thereby adjusting the shape of the mounting rod 32.

[0029] In a further embodiment, see Figure 3 A spring 44 is provided between the upper end of the fixed rod 42 and the movable groove 43. The spring 44 maintains pressure between the movable groove 43 and the fixed groove 41, thereby pressing the multiple protective plates 45 onto the fixed groove 41 to form protection.

[0030] In a further embodiment, see Figures 3-4 The protective plate 45 includes a raised back 451. The protective plate 45 is made of elastic material. The upper end of the protective plate 45 passes through the movable groove 43. Limiting blocks 452 are fixedly connected to both sides of the protective plate 45. The limiting blocks 452 are located below the movable groove 43.

[0031] The thickness of the protective plate 45 is reduced by the deformation of the raised back 451 under pressure. The pressure is buffered by the elasticity of the anti-slip plate 45 itself. At the same time, when the raised back 451 deforms, the two ends of the protective plate 45 extend to both sides. Since the fixing groove 41 below is fixed, the overall deformation of the protective plate 45 can only seek space upward. Thus, the movable groove 43 is lifted by the upward movement of the limiting block 452, and the buffering capacity of the protective mechanism is further improved by the spring 44.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
