Abstract
The utility model discloses a rock breaking cylinder, which comprises a cylinder body, wherein one end of the cylinder body is provided with a filling port, and the side wall of the cylinder body is contracted in the radial direction to be in a fold shape; by injecting the filler into the cylinder, the side walls are gradually stretched so that the cylinder expands outwards and forms pushing against the surrounding rock mass. The rock breaking cylinder gradually pushes the rock mass under the pressure effect, the process is mild and controllable, and severe vibration can not be generated, so that the influence on the nearby environment can be effectively reduced.
Description
Technical Field
The utility model mainly relates to the technical field of rock mass breaking, in particular to a rock breaking cylinder.
Background
In the prior art, rock is crushed in a blasting or impact mode, and the two crushing modes generate severe vibration in the operation process, and high decibel noise and dust are formed along with the severe vibration, so that the nearby environment is seriously affected. Accordingly, there is a need for a rock breaking device with less vibration.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide a rock breaking cylinder.
In order to solve the technical problems, the utility model adopts the following technical scheme:
a rock breaking cylinder comprises a cylinder body, wherein one end of the cylinder body is provided with a filling opening, and the side wall of the cylinder body is contracted in the radial direction to be in a fold shape; by injecting the filler into the cylinder, the side walls are gradually stretched so that the cylinder expands outwards and forms pushing against the surrounding rock mass.
As a further improvement of the above technical scheme:
the filling port is internally provided with a one-way valve.
Compared with the prior art, the utility model has the advantages that:
the rock breaking cylinder gradually pushes the rock mass under the pressure effect, the process is mild and controllable, and severe vibration can not be generated, so that the influence on the nearby environment can be effectively reduced.
Drawings
FIG. 1 is a schematic structural view of a rock breaking drum;
FIG. 2 is a schematic longitudinal section of the broken cylinder of example 1;
FIG. 3 is a schematic cross-sectional view of the rock breaking drum of example 1;
FIG. 4 is a schematic diagram of the working principle of a rock breaking cylinder;
fig. 5 is a schematic longitudinal section of the rock breaking cylinder of example 2.
The reference numerals in the drawings denote: 1. a filler neck; 2. a cylinder; 3. a sidewall; 4. a rock mass; 5. a one-way valve; 6. and (3) a hole.
Detailed Description
The utility model will be described in further detail with reference to the drawings and the specific examples.
Example 1
As shown in fig. 1 to 4, the rock breaking barrel of the present embodiment includes a barrel 2 having a filler opening 1 at one end, the filler opening 1 being adapted to be connected to an external injection device so that the external injection device injects filler into the barrel 2. The diameter of the cylinder 2 is reduced by the radial contraction of the side wall 3 thereof in the form of a corrugation, and in general, the diameter R1 of the corrugated cylinder 2 is equal to or slightly smaller than the diameter of the hole 6 in the rock mass 4, thereby enabling the cylinder 2 to be inserted smoothly into the hole 6. When the rock breaking operation is performed, the external injection device injects the filler (the filler can be high-pressure liquid or high-pressure gas) into the cylinder 2, the corrugated side wall 3 is gradually stretched due to the pressure difference between the inside and outside of the cylinder 2, the circumference of the side wall 3 is unchanged, the cylinder diameter of the cylinder 2 is gradually increased in the stretching process (when the side wall 3 is in a fully stretched state, the cylinder diameter R2 of the cylinder 2, R2 is more than R1), and after the cylinder diameter of the cylinder 2 is expanded to be consistent with the aperture of the hole 6 on the rock mass 4, the external injection device continuously pressurizes and injects the filler, so that the cylinder 2 is continuously expanded outwards to push the rock mass 4, and the rock mass 4 can be further driven to be broken. Compared with the prior art that rock is broken in a blasting or impact mode, the rock breaking barrel disclosed by the utility model gradually pushes the rock mass under the pressure effect, the process is mild and controllable, and severe vibration can not be generated, so that the influence on the nearby environment can be effectively reduced.
Example 2
As shown in fig. 5, a second embodiment of the present utility model, which is substantially the same as embodiment 1, is different in that: in this embodiment, the filler neck 1 has a check valve 5 built therein. After the rock breaking operation is finished, when the filling port 1 is separated from external injection equipment, the check valve 5 is arranged in the filling port 1, so that the filler can be effectively prevented from flowing back and out, and damage to personnel and equipment is avoided.
While the utility model has been described in terms of preferred embodiments, it is not intended to be limiting. Many possible variations and modifications of the disclosed technology can be made by anyone skilled in the art, or equivalent embodiments with equivalent variations can be made, without departing from the scope of the utility model. Therefore, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present utility model shall fall within the scope of the technical solution of the present utility model.
Claims (2)
1. A broken rock section of thick bamboo, its characterized in that: comprises a cylinder body (2) with a filling opening (1) at one end, wherein the side wall (3) of the cylinder body (2) is contracted in the radial direction to be in a fold shape; by injecting the filler into the cylinder (2), the side wall (3) is gradually stretched, so that the cylinder (2) expands outwards and pushes the surrounding rock mass (4).
2. A rock breaking cylinder according to claim 1, characterized in that: the filling port (1) is internally provided with a one-way valve (5).
