Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic breaker hammers, and in particular relates to a pressure stabilizing and dust reducing mechanism for a hydraulic breaker hammer. Background Art

[0002] Hydraulic breaker is an important engineering crushing tool. It is an impact device that converts hydraulic energy into mechanical energy. The hydraulic breaker is installed on the machine and connected to the hydraulic system. The high-pressure fluid of the hydraulic system is supplied to the hydraulic breaker to drive the piston rod to reciprocate. The piston rod hits the drill rod at high speed during the stroke, and the drill rod breaks the ore, concrete and other solids to complete the crushing task.

[0003] A hydraulic oil distribution and pressure constant device is arranged in the cylinder body of the hydraulic breaker. Since the hydraulic breaker is mostly used in some harsh environments, the hydraulic oil distribution and pressure constant device need to be frequently inspected and maintained. Therefore, the pressure stabilizing device inside the hydraulic breaker needs to be frequently disassembled. However, the existing hydraulic breakers mostly adopt an integrated or fixed installation manufacturing method, resulting in great resistance when disassembling the internal pressure stabilizing device. Furthermore, due to the complexity of the applicable environment, when performing the crushing task, the broken stones will generate a large amount of dust, and the emitted dust will block the user's sight and also pollute the on-site environment, affecting the crushing operation and construction. Finally, when disassembling the drill rod of the existing hydraulic breaker, it is necessary to manually hammer and knock it to remove it from the drill rod barrel. This method of operation is also very difficult.

[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes a hydraulic breaker pressure stabilizing and dust reduction mechanism. Summary of the invention

[0005] The purpose of the embodiment of the present invention is to provide a pressure stabilizing and dust reducing mechanism for a hydraulic breaker, in order to solve the problem.

[0006] The present invention is implemented in this way. A hydraulic breaker hammer pressure stabilizing dust reduction mechanism comprises: a hammer body, the interior of the hammer body is set as a cavity structure and a hydraulic oil cylinder lifting inlet and outlet are opened on the top, a hydraulic oil cylinder is installed inside the hammer body along the hydraulic oil cylinder lifting inlet and outlet, a drill rod barrel is connected and installed on the lower side of the hammer body corresponding to the output end at the bottom of the hydraulic oil cylinder, a drill rod is clamped and installed inside the drill rod barrel, a piston chamber is opened on the upper side of the drill rod barrel, the top of the piston chamber is connected with the bottom of the hydraulic oil cylinder, when the hydraulic oil cylinder is running, the bottom end of the piston rod inside the piston chamber is placed in the piston chamber for cyclic lifting, and then the top end of the drill rod placed in the piston chamber is cyclically hammered, thereby driving the outer end of the drill rod to be crushed;

[0007] The side wall of the hydraulic cylinder is elastically connected with the inner wall of the hammer body, that is, after the hydraulic cylinder moves to a certain distance along the lifting inlet and outlet of the hydraulic cylinder toward the inside of the hammer body, the hydraulic cylinder and the hammer body are automatically connected and positioned. At the same time, a lifting and splitting mechanism is arranged on the lower side of the hammer body, and the top of the lifting and splitting mechanism extends into the inner wall of the hammer body, squeezes and pushes out the side wall of the hydraulic cylinder and the inner wall of the hammer body, and the two are released from the locking and positioning, and then the hydraulic cylinder is pulled upward along the lifting inlet and outlet of the hydraulic cylinder to be disassembled and output. The cooperation between the lifting and splitting mechanism, the hydraulic cylinder and the hammer body is utilized to facilitate the rapid installation and disassembly and separation of the hydraulic cylinder and the hammer body, thereby facilitating the maintenance and replacement of the pressure stabilizing device inside the hydraulic cylinder, and ensuring that the drill rod can be in a stable pressure state during operation;

[0008] The atomizing dust suppression mechanism is installed on the outer side of the drill rod barrel in a lifting manner to atomize and clean the dust around the drill rod when it is running, reduce the diffusion of dust, and increase the protection of the construction personnel as well as the protection of the hammer and the drill rod itself;

[0009] The power transmission control component is arranged between the top of the atomizing dust reduction mechanism and the lifting and splitting mechanism, and the power transmission control component is controlled to operate so that the atomizing dust reduction mechanism is connected with the lifting and splitting mechanism for synchronous operation, or the lifting and splitting mechanism is separated from the atomizing dust reduction mechanism to release the power transmission operation, that is, the power transmission control component is used to transfer the kinetic energy in the atomizing dust reduction mechanism to the lifting and splitting mechanism, so as to provide power for the lifting and splitting mechanism to drive the hydraulic cylinder to dismantle, thereby increasing the kinetic energy utilization rate of the mechanism;

[0010] The pneumatic knocking assembly is arranged on one side of the outside of the drill rod tube. The pneumatic knocking assembly is used to automatically knock the positioning connection between the drill rod and the drill rod tube to release the clamping positioning restriction between the drill rod and the drill rod tube, that is, to speed up the disassembly of the drill rod. Compared with manual knocking, the knocking force and efficiency can be greatly increased.

[0011] The hydraulic breaker provided by the present invention provides a pressure stabilizing dust reduction mechanism, which starts the operation of the atomizing dust reduction mechanism, sprays water toward the outer end of the drill rod, and quickly settles and cleans the dust around the drill rod, thereby realizing the efficient dust reduction function of the breaker.

[0012] By starting the pneumatic knocking assembly, the restrictions on the drill rod and the drill rod barrel are released, and then the drill rod can be quickly dropped and disassembled. When it is necessary to disassemble the hydraulic cylinder from the inside of the hammer body for inspection and treatment, the jacking and disassembling mechanism is connected with the atomizing dust reduction mechanism by controlling the power transmission control member, so as to drive the jacking and disassembling mechanism to rise upward, release the elastic clamping connection between the hydraulic cylinder and the inner wall of the hammer body, and then pull the hydraulic cylinder to move outward along the hydraulic cylinder lifting inlet and outlet. That is, by combining the elastic clamping connection on the contact side between the hydraulic cylinder and the hammer body with the jacking and disassembling mechanism, the hydraulic cylinder can be quickly installed and disassembled, which is beneficial to the voltage stabilization and maintenance operation, and increases the voltage stabilization function of the breaker.

[0013] By arranging a pneumatic knocking assembly on the outside of the drill rod barrel to automatically knock and disassemble the drill rod, the convenience of replacing the drill rod is further increased. By arranging a power transmission control component to coordinate the atomization dust reduction mechanism with the lifting and splitting mechanism, the energy utilization efficiency of the mechanism is fully improved.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1-9 As shown, it is a structural diagram of a hydraulic breaker pressure stabilizing and dust reduction mechanism provided by an embodiment of the present invention, comprising: a hammer body 10, the interior of the hammer body 10 is set as a cavity structure and a hydraulic cylinder lifting inlet and outlet 13 is opened on the top, a hydraulic cylinder 14 is installed along the hydraulic cylinder lifting inlet and outlet 13 inside the hammer body 10 for lifting, a drill rod barrel 11 is connected and installed on the lower side of the hammer body 10 corresponding to the output end at the bottom of the hydraulic cylinder 14, a drill rod 12 is installed in the drill rod barrel 11, a piston chamber 15 is opened on the upper side of the drill rod barrel 11, and the top of the piston chamber 15 is connected to the bottom of the hydraulic cylinder 14. When the hydraulic cylinder 14 is running, the bottom end of the piston rod inside it is placed in the piston chamber 15 for cyclic lifting, and then the top end of the drill rod 12 placed in the piston chamber 15 is cyclically hammered, thereby driving the outer end of the drill rod 12 to be crushed;

[0032] The side wall of the hydraulic cylinder 14 is elastically connected with the inner wall of the hammer body 10, that is, after the hydraulic cylinder 14 moves to a certain distance along the hydraulic cylinder lifting inlet and outlet 13 toward the inside of the hammer body 10, the hydraulic cylinder 14 and the hammer body 10 are automatically connected and positioned. At the same time, a lifting and splitting mechanism 21 is provided on the lower side of the hammer body 10, and the top of the lifting and splitting mechanism 21 extends into the inner wall of the hammer body 10, and the side wall of the hydraulic cylinder 14 and the inner wall of the hammer body 10 are squeezed and pushed out, and the two are released from the locking and positioning, and then the hydraulic cylinder 14 is pulled upward along the hydraulic cylinder lifting inlet and outlet 13 to be disassembled and output. The cooperation between the lifting and splitting mechanism 21, the hydraulic cylinder 14, and the hammer body 10 is utilized to facilitate the rapid installation and disassembly of the hydraulic cylinder 14 and the hammer body 10, thereby facilitating the maintenance and replacement of the pressure stabilizing device inside the hydraulic cylinder 14, and ensuring that the drill rod 12 can be in a stable pressure state during operation;

[0033] The atomizing dust suppression mechanism 20 is arranged on the outer side of the drill rod tube 11 in a lifting manner, and is used to atomize and clean the dust around the drill rod 12 when it is running, thereby reducing the diffusion of dust, increasing the protection of the construction personnel, and the protection of the hammer body 10 and the drill rod 12 itself;

[0034] The power transmission control member is arranged between the top of the atomizing dust reduction mechanism 20 and the lifting and splitting mechanism 21, and controls the operation of the power transmission control member, so that the atomizing dust reduction mechanism 20 and the lifting and splitting mechanism 21 are connected and run synchronously, or the lifting and splitting mechanism 21 and the atomizing dust reduction mechanism 20 are separated and the power transmission operation is released, that is, the power transmission control member is used to transfer the kinetic energy in the atomizing dust reduction mechanism 20 to the lifting and splitting mechanism 21, so as to provide power for the lifting and splitting mechanism 21 to drive the hydraulic cylinder 14 to disassemble, thereby increasing the kinetic energy utilization rate of the mechanism;

[0035] The pneumatic knocking assembly 19 is arranged on one side of the outside of the drill rod tube 11. The pneumatic knocking assembly 19 is used to automatically knock the positioning connection between the drill rod 12 and the drill rod tube 11 to release the clamping positioning restriction between the drill rod 12 and the drill rod tube 11, that is, to speed up the disassembly of the drill rod 12. Compared with manual knocking, the knocking force and efficiency can be greatly increased;

[0036] The hydraulic cylinder 14 is moved toward the inside of the hammer body 10 through the hydraulic cylinder lifting inlet and outlet 13. When the output end at the bottom of the hydraulic cylinder 14 moves to the top of the drill rod tube 11 and is connected to the piston chamber 15, the two sides of the hydraulic cylinder 14 are elastically positioned between the inner wall of the hammer body 10, and then the top of the drill rod 12 is clamped into the inside of the drill rod tube 11. At this time, the breaker hammer is installed. Under the operation of the hydraulic cylinder 14, the drill rod 12 is driven to cyclically rise and fall to knock and crush the external ground or rock. At this time, the atomizing dust reduction mechanism 20 is started during the operation, and water is sprayed toward the outer end of the drill rod 12 to quickly settle and clean the dust around the drill rod 12. When the drill rod 12 needs to be replaced and disassembled, the pneumatic knocking assembly 19 is started to operate, and the restrictions on the drill rod 12 and the inside of the drill rod tube 11 are released. Then the drill rod 12 can be quickly dropped and disassembled. When the hydraulic cylinder 14 needs to be disassembled from the inside of the hammer body 10 for inspection and treatment, the power is controlled. The transmission control component transmits and connects the lifting and splitting mechanism 21 with the atomizing dust reduction mechanism 20, drives the lifting and splitting mechanism 21 to rise upward, releases the elastic clamping connection between the hydraulic cylinder 14 and the inner wall of the hammer body 10, and then pulls the hydraulic cylinder 14 to move outward along the hydraulic cylinder lifting inlet and outlet 13, that is, by elastically clamping the lifting and splitting mechanism 21 on the contact side between the hydraulic cylinder 14 and the hammer body 10, the hydraulic cylinder 14 can be quickly installed and removed, which is beneficial to the voltage stabilization and maintenance operation. By arranging the atomizing dust reduction mechanism 20 in a lifting manner on the outside of the drill rod barrel 11, it is convenient to carry out adjustable dust reduction treatment for dust of different densities, and a pneumatic knocking assembly 19 is arranged on the outside of the drill rod barrel 11 to automatically knock and disassemble the drill rod 12, further increasing the convenience of replacing the drill rod 12, and by arranging the power transmission control component, the atomizing dust reduction mechanism 20 is transmitted and matched with the lifting and splitting mechanism 21, so as to fully improve the energy utilization efficiency of this mechanism.

The positions of the above structures distributed in the hydraulic cylinder 14 and the connection and operation relationship between them are all conventional structures, which will not be described in detail here.

[0039] It should be noted that the bottom output end of the hydraulic cylinder 14 is in contact communication with the top of the piston chamber 15, and a sealing ring is provided at the edge of the connection to maintain the sealing after the two are connected, that is, to prevent the liquid inside the hydraulic cylinder 14 from leaking out.

[0041] The atomization height lifting component includes a nut 32 installed on a water tank fixing ring 33, a lead screw 31 is connected to the middle of the nut 32 through a longitudinal thread, a guide device for limiting its rotation is provided on the nut 32, a servo motor 29 is connected to the bottom end of the lead screw 31, and the servo motor 29 is detachably installed on the outer wall of the drill rod tube 11 through a telescopic positioning member 30 on one side of the drill rod tube 11, that is, the servo motor 29 is started to drive the lead screw 31 to rotate, and then the nut 32 is driven to move up and down along the lead screw 31, and then the height of the atomization nozzle 35 is adjusted under the connection with the water tank fixing ring 33;

[0042] The telescopic positioning member 30 includes two telescopic screws and a screw barrel. The two telescopic screws are respectively threadedly connected to the two ends of the screw barrel. The ends of the two telescopic screws away from the screw barrel are respectively fixedly connected to the side wall of the servo motor 29 and plugged into the outer wall of the drill rod barrel 11. The telescopic screws are provided with a clamping hole on the outer wall of the drill rod barrel 11.

The limit block 24 is used to prevent the elastic locating pin 22 from escaping from the buffer cavity 23. A spring 25 is elastically connected to the side of the limit block 24 facing the inner wall of the buffer cavity 23. Under the elastic action of the spring 25, the lateral elastic movement ability of the elastic locating pin 22 is realized. When the spring 25 is in a free state, the elastic locating pin 22 is controlled to be in a maximum extension state, and the end of the elastic locating pin 22 is set to an arc structure. When the elastic locating pin 22 follows the hydraulic cylinder 14 to move toward the inside of the hammer body 10, when moving the corresponding clamping hole, under the rebound force of the spring 25, the elastic locating pin 22 is automatically clamped into the clamping hole, that is, the hydraulic cylinder 14 and the hammer body 10 are laterally positioned, and the elastic locating pins 22 at the upper and lower parts of the same side are synchronously clamped or separated with the clamping holes on the inner wall of the corresponding hammer body 10.

When the push block 50 is driven to move to the clamping hole, the elastic positioning pin 22 inserted into the clamping hole is pushed by the push block 50 to move it out of the clamping hole. At this time, the lateral resistance between the hydraulic cylinder 14 and the hammer body 10 is lost, and then the hydraulic cylinder 14 can be pulled upward to realize the automatic lifting and disassembly function of the hydraulic cylinder 14;

[0048] The bottom of the lifting and lowering assembly is connected to the power transmission control component. The lifting and lowering assembly includes a U-shaped rod installed at the bottom of the lifting rods 49 on both sides. A nut 48 is connected to one side of the U-shaped rod.

A pin cap 18 is installed on the outer end of the locking pin 17. A fastening expansion groove is provided on the outer side of the end of the locking pin hole 16 corresponding to the pin cap 18. When the locking pin 17 is inserted into the drill rod barrel 11 along the locking pin hole 16, the two sides of the locking pin 17 are clamped at the arc-shaped notches on both sides of the drill rod 12, that is, it is used to prevent the drill rod 12 from escaping outward along the drill rod barrel 11, and at the same time, the pin cap 18 is secured. When the external force is applied, the locking pin 17 is inserted into the fastening expansion groove and is fully fixed in the locking pin hole 16. When the drill rod 12 needs to be disassembled, the locking pin 17 needs to be moved out of the locking pin hole 16 in advance. At this time, the pneumatic knocking assembly 19 is arranged outside the locking pin hole 16 away from the fastening expansion groove. The pneumatic knocking assembly 19 is started to apply a thrust toward the inside of the locking pin hole 16, and the locking pin 17 is knocked from the other end to push the locking pin 17 out of the locking pin hole 16, thereby realizing the automatic operation when the drill rod 12 is disassembled;

[0053] The pneumatic knocking assembly 19 includes two push rods located outside the locking pin hole 16, and the ends of the two push rods are connected to a connecting rod 28. One end of the connecting rod 28 is connected to a cylinder 26. The bottom of the cylinder 26 is installed on the outer wall of the drill rod tube 11 through a base plate 27. That is, starting the cylinder 26 drives the connecting rod 28 to move radially, and then drives the push rod to move toward the locking pin hole 16, applying an outward thrust to the locking pin 17.
