A mechanism to prevent the wedges of a splitter from opening excessively.

Abstract

This utility model discloses a mechanism to prevent excessive opening of the wedges in a rock splitter, belonging to the field of rock splitter technology. It includes a housing with a drive module inside, a wedge tooth at one end of the housing, and a piston block on the outer wall of the drive module; a limiting component installed at one end of the housing, with the wedge tooth located inside the limiting component; and a protective component disposed between the piston block and the housing. In this utility model, after the wedge tooth is pulled out of the hole, the limiting ring and anti-slip block can restrict the wedge tooth, thereby preventing excessive opening angle caused by shaking due to device movement.

Description

Technical Field

[0001] This utility model belongs to the field of splitting machine technology, and in particular relates to a mechanism for preventing the wedges of a splitting machine from opening excessively. Background Technology

[0002] A rock splitter is a device used to statically fracture hard materials such as rocks and concrete. It is mainly operated by hydraulic or mechanical principles. When fracturing materials, the splitting gun is inserted into a pre-drilled hole. High pressure pushes the wedge in the splitting gun to move, thereby generating a large lateral thrust, which causes the object to crack.

[0003] During the use of a rock splitter, after the wedge is removed from the rock or other materials, the wedge itself is movable, and because it lacks a restraint after removal, it is prone to opening to both sides due to the shaking caused by the movement of the device. This will affect the insertion of it into the opening when used again. In order to solve the above problem, there is an urgent need for a mechanism to prevent the wedge of the rock splitter from opening excessively. Utility Model Content

[0004] The purpose of this invention is to provide a mechanism to prevent the wedges of a splitting machine from opening excessively, in order to solve the problem that the wedges may move and open due to the shaking of the device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mechanism for preventing excessive opening of the wedge block of a splitting machine, comprising a housing, a drive module provided inside the housing, a wedge tooth provided at one end of the housing, and a piston block provided on the outer wall of the drive module; a limiting component, the limiting component being installed at one end of the housing, with the wedge tooth located inside the limiting component; and a protective component, the protective component being disposed between the piston block and the housing. The limiting component includes a limiting ring sleeved on the outside of the wedge teeth, which limits the opening range of the wedge teeth, and the outer wall of the limiting ring is equipped with an anti-slip block.

[0006] As a further description of the above technical solution: The outer wall of the limiting ring is equipped with a pull rope, and the pull rope is made of a flexible material that can be bent.

[0007] As a further description of the above technical solution: The other end of the pull rope is equipped with a fixing plate, which is fixedly connected to the outer wall of the outer shell.

[0008] As a further description of the above technical solution: The protective component includes a protective cover, one end of which is fixedly connected to the inner wall of the outer shell, and the other end of which is fitted onto the outer wall of the piston block.

[0009] As a further description of the above technical solution: A connecting ring is installed on the inner wall of the protective cover, and the connecting ring is connected to the piston block through a groove opened on the outer wall of the piston block.

[0010] As a further description of the above technical solution: A fixing ring is installed on one side of the inner wall of the protective cover. A bolt is provided inside the fixing ring. The bolt is threadedly connected to the piston block through a threaded hole on one side of the piston block.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, after the wedge tooth is pulled out of the hole, the wedge tooth can be restricted by the limiting ring and the anti-blocking block, thereby avoiding the problem of the wedge tooth opening too large due to the shaking caused by the movement of the device. At the same time, when the wedge tooth is inserted into the ground, the limiting ring is blocked by the ground, so that the limiting ring no longer obstructs the wedge tooth, and the wedge tooth can open smoothly for operation.

[0012] In this invention, by installing a protective cover on one side of the piston block, and since the other end of the protective cover is fixed to the inner wall of the outer shell, the position where the outer side of the piston block contacts the inner wall of the outer shell can be isolated from the inside of the protective cover. This prevents dust and other contaminants from entering the inner wall of the outer shell and affecting the piston's seal, thereby ensuring the stable operation of the piston.

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In its specific implementation, such as Figures 1-4 This utility model provides a technical solution: a mechanism to prevent the wedge of a splitting machine from opening excessively, including a housing 1, a drive module 2 inside the housing 1, a wedge tooth 3 at one end of the housing 1, and a piston block 6 on the outer wall of the drive module 2; a limiting component 4, which is installed at one end of the housing 1 and the wedge tooth 3 is located inside the limiting component 4; and a protective component 5, which is disposed between the piston block 6 and the housing 1. The limiting component 4 includes a limiting ring 44 sleeved on the outside of the wedge tooth 3, which limits the opening range of the wedge tooth 3. The limiting ring 44 is equipped with an anti-slip block 43 on its outer wall and a pull rope 42 on its outer wall. The pull rope 42 is made of a flexible material that can be bent. A fixing plate 41 is installed at the other end of the pull rope 42, and the fixing plate 41 is fixedly connected to the outer wall of the outer shell 1.

[0020] Specifically, during use, as the wedge tooth 3 is inserted into the pre-drilled hole, the limiting ring 44 falls down and lands on the ground or the surface of the material to be mined, causing the pull rope 42 to bend. When the wedge tooth 3 is pulled out of the hole, the pull rope 42 is gradually stretched as the device moves upward. After the wedge tooth 3 is pulled out of the hole, the limiting ring 44 can be fitted onto the outer wall of the wedge tooth 3, and the anti-slip block 43 can be brought close to the wedge tooth 3. Thus, the limiting ring 44 and the anti-slip block 43 prevent the wedge tooth 3 from opening excessively. like Figure 4 As shown, the protective component 5 includes a protective cover 51. One end of the protective cover 51 is fixedly connected to the inner wall of the outer shell 1, and the other end of the protective cover 51 is sleeved on the outer wall of the piston block 6. A connecting ring 52 is installed on the inner wall of the protective cover 51. The connecting ring 52 is connected to the piston block 6 through a groove opened on the outer wall of the piston block 6. A fixing ring 53 is installed on one side of the inner wall of the protective cover 51. A bolt 54 is provided in the fixing ring 53. The bolt 54 is threadedly connected to the piston block 6 through a threaded hole opened on one side of the piston block 6. Specifically, when installing the protective cover 51, it is fixed to the piston block 6 by bolts 54. At the same time, as the bolts 54 are tightened, the protective cover 51 is squeezed by the fixing ring 53, which causes the protective cover 51 to deform to a certain extent. The deformation of the protective cover 51 allows the connecting ring 52 to fit tightly into the groove on the outer wall of the piston block 6, thereby ensuring the sealing of the connection between the protective cover 51 and the piston block 6.

[0021] Working principle: When installing the protective cover 51, it is fixed by connecting it to the piston block 6 with bolts 54. As the bolts 54 are tightened, the protective cover 51 is squeezed by the fixing ring 53, causing the protective cover 51 to deform. This deformation allows the connecting ring 52 to fit tightly into the groove on the outer wall of the piston block 6, ensuring the sealing of the connection between the protective cover 51 and the piston block 6. In use, when the wedge tooth 3 is inserted into the pre-drilled hole, the limiting ring 44 falls to the ground or the surface of the material to be mined. When the wedge tooth 3 is pulled out of the hole, the pull rope 42 is gradually stretched as the device moves upward. After the wedge tooth 3 is pulled out of the hole, the limiting ring 44 can be sleeved on the outer wall of the wedge tooth 3, allowing the anti-slip block 43 to come close to the wedge tooth 3. The limiting ring 44 and the anti-slip block 43 prevent the wedge tooth 3 from opening excessively.
