Description

Technical Field

[0001] This invention relates to the field of high-frequency hydraulic breaker technology, specifically a high-frequency hydraulic breaker with a bracket structure. Background Technology

[0002] A high-frequency hydraulic breaker is a crushing device that operates on the core principle of high-frequency reciprocating impact. It typically generates high-frequency vibration and impact energy through an internal eccentric mechanism and vibration components driven by hydraulics or an electric motor. This energy is then transmitted to the objects to be crushed, such as rocks, concrete, and road surfaces, via actuators such as chisels, to achieve efficient crushing operations. It is a specialized attachment widely used in mining, road construction, and building demolition. Its core advantages lie in its high crushing frequency, high operating efficiency, and minimal disturbance to surrounding structures.

[0003] The core purpose of setting up the bracket structure is to provide stable support for the high-frequency breaker, optimize power transmission, and enhance operational safety. The bracket structure, through components such as connecting plates, transmission plates, and positioning rods, forms an integrated installation and support frame. It can accurately position and firmly connect core components such as the drive motor, eccentric transmission mechanism, and breaker body, ensuring the installation stability of each component in a high-frequency vibration environment and preventing loosening or displacement due to vibration. It can also provide a reliable carrier for power transmission, so that the reciprocating motion of the eccentric mechanism is efficiently converted into the lifting and lowering impact of the breaker body, reducing energy loss.

[0004] Currently, the bracket structures used in existing high-frequency hydraulic breakers are mostly driven by a single eccentric shaft or simple shaft contact transmission. The matching structures used for positioning and buffering are relatively simple, which makes the rotation trajectory prone to deviation. Moreover, the eccentric shafts mostly collide directly with each other. After frequent collisions, not only will severe vibrations be generated, but collision damage between the eccentric shafts will also be caused. After long-term collisions, the eccentric shafts will break, which can easily lead to transmission jamming problems, affecting the stability of the crushing frequency. There is a lack of effective buffering mechanism in the power transmission process. The vibration and impact generated by the reciprocating rotation of the eccentric shaft are directly transmitted to the whole equipment, resulting in poor stability of the reciprocating lifting and lowering motion of the hydraulic breaker body. It is prone to swaying and deviation, which reduces the crushing force and efficiency, causes wear on the core components of the equipment, and reduces the service life of the equipment.

[0005] Therefore, this invention proposes a high-frequency hydraulic breaker with a bracket structure to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a high-frequency hydraulic breaker with a bracket structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-frequency breaker with a bracket structure, including a control box and a drive motor, connecting plates are fixedly installed on both sides of the control box surface, a transmission plate is fixedly installed on one side of the connecting plate surface, and the drive motor is fixedly installed on one side of the transmission plate surface.

[0008] A positioning rod is fixedly installed on one side of the bottom of the connecting plate, and a breaker body is fixedly installed on one side of the surface of the positioning rod. A protective plate is fixedly installed on the outer surface of the breaker body. A sliding groove is opened at the center of one side of the top surface of the connecting plate, and an installation plate is slidably installed on the surface of the sliding groove. Grooves are opened on both sides of the surface of the control box.

[0009] A lower eccentric shaft is fixedly installed on one side of the transmission plate surface. A connecting rod is fixedly installed on one side of the lower eccentric shaft surface. A lower arc plate is fixedly sleeved on the top surface of the connecting rod. A fixed plate is fixedly installed on the top of the transmission plate. An upper eccentric shaft is rotatably installed at both ends on one side of the fixed plate surface. A fixed rod is fixedly installed at the center of the bottom of the inner side of the upper eccentric shaft. An upper arc plate is fixedly sleeved on the surface of the fixed rod.

[0010] Preferably, the lower eccentric shaft and the upper eccentric shaft are gourd-shaped, and the lower eccentric shaft is driven by a drive motor to rotate the transmission plate, which rotates on both sides inside the control box and makes rotational contact with one side of the surface of the upper eccentric shaft.

[0011] Preferably, the lower eccentric shaft rotates inside the control box and is engaged with the groove surface.

[0012] Preferably, the rotation of the lower eccentric shaft synchronously drives the connecting rod and the lower arc plate to rotate along the lower eccentric shaft, with one side of the surface of the lower arc plate corresponding to the surface of the upper arc plate, so that the surfaces of the lower arc plate and the upper arc plate rotate and engage.

[0013] Preferably, a torsion spring is fixedly sleeved on one side of the upper eccentric shaft surface, and the lower arc plate is rotatably engaged with the surface of the upper arc plate. The torsion spring drives the upper eccentric shaft to rotate and adjust, while the lower eccentric shaft drives the connecting rod and the lower arc plate to rotate. The lower eccentric shaft engages with the upper arc plate and, combined with the elastic reset effect of the torsion spring, enables the upper eccentric shaft to achieve smooth reciprocating rotation, reducing direct collision between the upper and lower eccentric shafts, providing a buffering and protective effect, and also preventing transmission jamming.

[0014] Preferably, the lower arc plate is located on one side of the lower arc plate surface. When the lower arc plate is rotated and engaged with the surface of the upper arc plate, and the highest position of the lower eccentric shaft is rotated and contacted again with the bottom of the upper eccentric shaft, the upper eccentric shaft is driven to rotate back and forth for adjustment.

[0015] Preferably, a push rod is fixedly installed on the top surface of the upper eccentric shaft, and a buffer spring is fixedly installed on the top of the push rod. The top of the buffer spring is fixedly connected to the bottom of the mounting plate.

[0016] Preferably, the upper eccentric shaft is adjusted by rotating and engaging with the lower arc plate and the upper arc plate, simultaneously driving the top rod and the buffer spring to rise and fall. The control box reciprocates at the top of the upper eccentric shaft via a sliding groove. The reciprocating rotation of the upper eccentric shaft is transmitted to the buffer spring through the top rod. The buffer spring not only absorbs vibration impact but also drives the mounting plate to slide along the sliding groove of the connecting plate, enabling the control box to drive the breaker body to achieve stable reciprocating lifting and crushing. The elastic buffering of the buffer spring effectively reduces vibration damage to the overall equipment during the crushing process.

[0017] Preferably, the breaker body is fixedly connected to the control box via a positioning rod and a protective plate, which synchronously drives the breaker body to reciprocate up and down at the bottom of the control box.

[0018] Preferably, the upper eccentric shaft is adjusted by reciprocating rotation on the top surface of the lower eccentric shaft via a torsion spring.

[0019] Compared with the prior art, the beneficial effects of the present invention are: The cooling device for cooling fine enameled wires proposed in this invention effectively resists flying debris and impacts during crushing operations through a protective plate, preventing damage to the device itself. When the drive motor drives the lower eccentric shaft to rotate, its gourd-shaped structure engages with the groove in the control box, ensuring precise rotation trajectory and driving the upper eccentric shaft through rotational contact. Simultaneously, the lower eccentric shaft drives the connecting rod and lower arc plate to rotate, engaging with the upper arc plate and combining with the elastic reset action of the torsion spring, enabling the upper eccentric shaft to achieve smooth reciprocating rotation. This reduces direct collision between the upper and lower eccentric shafts, providing a buffering and protective effect, and also avoids transmission... The reciprocating rotation of the upper eccentric shaft is transmitted to the buffer spring through the push rod. The buffer spring not only absorbs vibration impact but also drives the mounting plate to slide along the groove of the connecting plate, enabling the control box to drive the breaker body to achieve stable reciprocating lifting and crushing. The elastic buffer of the buffer spring effectively reduces the vibration damage to the overall equipment during the crushing process. The overall structure, through the coordinated transmission of the lower and upper eccentric shafts and the double elastic protection of the torsion spring and buffer spring, not only improves the reciprocating crushing frequency and force of the breaker body and ensures crushing efficiency, but also effectively enhances the operational stability of the equipment through the protective plate, multiple positioning structure and elastic buffer design.

[0022] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0023] Please see Figure 1 A high-frequency breaker with a bracket structure includes a control box 100 and a drive motor 200. A connecting plate 101 is fixedly installed on both sides of the surface of the control box 100, and a transmission plate 201 is fixedly installed on one side of the surface of the connecting plate 101. The drive motor 200 is fixedly installed on one side of the surface of the transmission plate 201.

[0024] A positioning rod 212 is fixedly installed on one side of the bottom of the connecting plate 101. A breaker body 103 is fixedly installed on one side of the surface of the positioning rod 212. A protective plate 213 is fixedly installed on the outer surface of the breaker body 103. A sliding groove 105 is opened at the center of one side of the top surface of the connecting plate 101. An installation plate 102 is slidably installed on the surface of the sliding groove 105. Grooves 104 are opened on both sides of the surface of the control box 100.

[0025] The lower eccentric shaft 207 rotates inside the control box 100 and is rotatably engaged with the surface of the groove 104.

[0026] In use, the control box 100 forms a stable mounting and transmission base with the transmission plate 201 via the connecting plates 101 on both sides. The drive motor 200 is fixed to one side of the transmission plate 201 to provide a power source. The positioning rod 212 at the bottom of the connecting plate 101 provides reliable positioning support for the breaker body 103. At the same time, the protective plate 213 on the outer surface of the breaker body 103 forms a protective layer for operation. After the drive motor 200 starts, it drives the lower eccentric shaft 207 to rotate inside the control box 100. The lower eccentric shaft 207 and the grooves 10 on both sides of the surface of the control box 100 are connected. 4. A rotating snap-fit ​​is formed to ensure that the rotation trajectory of the lower eccentric shaft 207 is stable and without deviation. The eccentric power generated during the rotation of the lower eccentric shaft 207 is transmitted to the connecting plate 101 through the transmission structure, which drives the connecting plate 101 and the control box 100 fixed thereto to move synchronously. The sliding fit between the top slide groove 105 of the connecting plate 101 and the mounting plate 102 provides guidance and limit for the movement of the control box 100, so that the control box 100 drives the breaker hammer body 103 fixed at the bottom by the positioning rod 212 to achieve stable reciprocating motion, thereby completing the high-frequency crushing operation.

[0027] Combined with the appendix Figure 3-6 As shown, a lower eccentric shaft 207 is fixedly installed on one side of the surface of the transmission plate 201, a connecting rod 208 is fixedly installed on one side of the surface of the lower eccentric shaft 207, a lower arc plate 209 is fixedly sleeved on the top surface of the connecting rod 208, a fixing plate 202 is fixedly installed on the top of the transmission plate 201, an upper eccentric shaft 203 is rotatably installed at both ends on one side of the surface of the fixing plate 202, a fixing rod 210 is fixedly installed at the center of the bottom of the inner side of the upper eccentric shaft 203, and an upper arc plate 211 is fixedly sleeved on the surface of the fixing rod 210.

[0028] The lower eccentric shaft 207 and the upper eccentric shaft 203 are gourd-shaped. The lower eccentric shaft 207 drives the transmission plate 201 to rotate through the drive motor 200, rotating on both sides inside the control box 100 and rotating in contact with one side of the surface of the upper eccentric shaft 203.

[0029] The lower eccentric shaft 207 rotates, synchronously driving the connecting rod 208 and the lower arc plate 209 to rotate along the lower eccentric shaft 207. One side of the surface of the lower arc plate 209 corresponds to the surface of the upper arc plate 211, so that the lower arc plate 209 and the surface of the upper arc plate 211 rotate and engage.

[0030] A torsion spring 206 is fixedly sleeved on one side of the surface of the upper eccentric shaft 203. The lower arc plate 209 is rotatably engaged with the surface of the upper arc plate 211. The upper eccentric shaft 203 is rotated and adjusted by the torsion spring 206.

[0031] In use, after the drive motor 200 starts, it drives the transmission plate 201 to rotate, which in turn drives the lower eccentric shaft 207 to rotate on both sides inside the control box 100. During the rotation, not only does the surface of the lower eccentric shaft 207 form rotational contact with one side of the surface of the upper eccentric shaft 203, but it also simultaneously drives the connecting rod 208 and the lower arc plate 209 fixedly sleeved on its top to rotate around the lower eccentric shaft 207. Since one side of the surface of the lower arc plate 209 corresponds to the position of the upper arc plate 211 on the bottom fixing rod 210 of the upper eccentric shaft 203, when the lower arc plate 209 rotates to the corresponding position, it forms a rotational engagement with the upper arc plate 211. At this time, the upper... The torsion spring 206, which is sleeved on one side of the surface of the eccentric shaft 203, is compressed and undergoes elastic deformation. When the lower arc plate 209 rotates with the lower eccentric shaft 207 and disengages from the upper arc plate 211, the torsion spring 206 releases elastic potential energy to drive the upper eccentric shaft 203 to rotate in the opposite direction and reset. Through the continuous rotation of the lower eccentric shaft 207, the lower arc plate 209 and the upper arc plate 211 are periodically engaged and disengaged. Combined with the elastic reset effect of the torsion spring 206, the upper eccentric shaft 203 is finally driven to complete a stable reciprocating rotation, providing a power transmission basis for the subsequent reciprocating crushing motion of the breaker body 103.

[0032] Finally, combined with the appendix Figure 2 and Figure 5 As shown, the lower arc plate 209 is disposed on one side of the surface of the lower arc plate 209. When the lower arc plate 209 is rotated and engaged with the surface of the upper arc plate 211, and the highest position of the lower eccentric shaft 207 is rotated and contacted with the bottom of the upper eccentric shaft 203 again, the upper eccentric shaft 203 is driven to reciprocate and adjust.

[0033] A push rod 204 is fixedly installed on the top surface of the upper eccentric shaft 203, and a buffer spring 205 is fixedly installed on the top of the push rod 204. The top of the buffer spring 205 is fixedly connected to the bottom of the mounting plate 102.

[0034] The upper eccentric shaft 203 is adjusted by rotating and engaging with the upper arc plate 211 and the lower eccentric shaft 207 via the lower arc plate 209, which simultaneously drives the top rod 204 and the buffer spring 205 to rise and fall. The control box 100 reciprocates and rises and falls on the top of the upper eccentric shaft 203 via the slide groove 105.

[0035] The upper eccentric shaft 203 is adjusted by reciprocating rotation on the top surface of the lower eccentric shaft 207 via a torsion spring 206.

[0036] The breaker body 103 is fixedly connected to the control box 100 via the positioning rod 212 and the protective plate 213, which synchronously drives the breaker body 103 to reciprocate up and down at the bottom of the control box 100.

[0037] In use, the top rod 204 fixed to the top of the upper eccentric shaft 203 moves up and down synchronously with its reciprocating rotation, thereby driving the buffer spring 205 connected to the top to extend and retract. The top of the buffer spring 205 is fixedly connected to the bottom of the mounting plate 102, and the mounting plate 102 is slidably installed in the slide groove 105 of the connecting plate 101. This allows the up and down movement of the top rod 204 and the buffer spring 205 to be converted into the reciprocating up and down movement of the control box 100 through the guide limit of the slide groove 105. Since the breaker body 103 is fixedly connected to the control box 100 through the positioning rod 212 and the protective plate 213, the reciprocating up and down movement of the control box 100 will synchronously drive the breaker body 103 to achieve reciprocating up and down movement at its bottom. At the same time, the buffer spring 205 absorbs vibration and impact during the movement, ensuring the stability of the overall movement. Finally, the breaker body 103 completes the crushing operation through high-frequency reciprocating up and down movement.

[0038] 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.
