Description

Technical Field

[0001] This invention relates to the field of hydraulic hammer technology, specifically to a support device for a hydraulic hammer. Background Technology

[0002] A hydraulic hammer is an engineering tool used to break and excavate various hard materials in construction, excavation, mining and demolition projects. It can crush rocks and reinforce and compact soft ground, and has a powerful impact force as well as a low level of vibration and noise.

[0003] Patent publication number CN209793640U discloses a support device for a hydraulic hammer in the field of crushing and compaction equipment. Specifically, it includes a support frame and baffles. The support frame is a frame structure fitted onto the outside of the hydraulic hammer body, allowing the hammer body to move up and down along the inside of the support frame. The lower end of the support frame rests on the ground or a supporting surface. Multiple baffles are installed on the outside of the support frame, enclosing its exterior. This patent provides effective support for the hydraulic hammer, preventing tilting and misfiring, and also prevents debris from flying everywhere. It features a reasonable structure and improves equipment safety.

[0004] Currently, hydraulic hammers on the market still have the following problems: In some construction engineering environments, a lot of broken stones will be ejected during the use of hydraulic hammers. These broken stones will pose a safety hazard to the construction workers. Furthermore, during the jumping process of the hydraulic hammer, once it collides with the inclined surface of the stone or solids that are not crushed in one go, it will cause the hydraulic hammer to tilt, which will bring even greater safety hazards. Therefore, it is necessary to design a hydraulic hammer with a support function. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a support device for a hydraulic hammer, which solves the problems mentioned in the background art, such as the ejection of many stones during the use of a hydraulic hammer in some construction engineering environments, which poses a safety hazard to construction workers, and the tilting of the hydraulic hammer during its movement if it collides with a sloping stone or a solid that is not crushed in one go, which would bring even greater safety hazards.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support device for a hydraulic hammer, comprising a hydraulic hammer with a vertical slide rail on its back, and a protective device, an adjustment device, a distance measuring device, and an anti-jamming device on the outside of the hydraulic hammer; the protective device includes a protective cover, a support foot, a hydraulic spring rod, and a support block; the inner wall of the protective cover is fixed to the back of the vertical slide rail, the support foot is fixed to the bottom of the outer wall of the protective cover, the top end of the hydraulic spring rod is hinged to the outside of the support foot, and the support block is hinged to the bottom end of the hydraulic spring rod. In engineering environments, when hydraulic hammers are used, the impact pressure often causes damage to ground stones, thus affecting some... When rock fragments fly out, they can easily injure people if they hit them. Furthermore, the impact can cause the hydraulic hammer to tilt and collapse, leading to more serious safety accidents. Therefore, during hydraulic hammer operation, an external protective cover is used to block flying rocks. At the same time, when the hydraulic hammer tilts due to impact, the support legs increase the contact area between the device and the bottom surface, improving stability. When the hydraulic hammer tilts, it causes the vertical slide rail to tilt, which in turn causes the protective cover to tilt. The protective cover then compresses the hydraulic spring rod, which, together with the support block, absorbs the kinetic energy generated by the tilt and springs back the device to straighten it, greatly improving the anti-tipping effect of the device.

[0007] According to the above technical solution, the protective device also includes a long frame, a hydraulic push rod, and an extended base plate. The long frame is fixed to the top of the support foot, the hydraulic push rod is fixed to the bottom surface of the long frame, and the telescopic end of the hydraulic push rod passes through the top surface of the support foot. The extended base plate is fixed to the telescopic end of the hydraulic push rod. Before placing the hydraulic hammer and the protective cover, the ground generally needs to be leveled to a certain extent. Uneven ground may prevent the device from being deployed. When there is a slight level difference in the ground, the hydraulic push rod can be activated to push the extended base plate, which fills the gap between the support foot and the ground, so that the entire device can maintain a horizontal working state, thereby avoiding tilting accidents.

[0008] According to the above technical solution, the adjusting device includes a telescopic slider, a sliding frame, a telescopic rod, a connecting plate, a first telescopic plate, a scraper ring, and a push plate. The telescopic slider is slidably installed on the inner wall of the vertical slide rail. The sliding frame is fixed to the telescopic end of the telescopic slider. The telescopic rod is fixed to both sides of the inner wall of the sliding frame, and the telescopic end of the telescopic rod is fixed to both sides of the hydraulic hammer. The connecting plate is fixed to the bottom of the sliding frame. The first telescopic plate is fixed to the bottom of the connecting plate. The scraper ring is fixed to the side of the first telescopic plate away from the connecting plate. The push plate is fixed to the top surface of the telescopic end of the first telescopic plate. The push plate is located on the movement trajectory of the hydraulic hammer. Because of the protective cover, the hydraulic hammer may not be accurately positioned at the work site when placed there. Therefore, the telescopic slider can be activated, which pushes the sliding frame, and the sliding frame pushes the hydraulic hammer. This allows for adjustment of the hydraulic hammer's front and rear positioning. Then, the telescopic rod is activated, pushing the hydraulic hammer left and right to further adjust its position. This enables the hydraulic hammer to move within the protective cover, allowing for secondary positioning after device placement and expanding the construction area beyond the designated point. When the hydraulic hammer adjusts its position, it pushes the push plate, which in turn pushes the telescopic plate, causing it to retract. The telescopic plate then pulls the scraper ring, ensuring synchronized movement between the scraper ring and the hammer head. During operation, some soil and stones may adhere to the bottom and sides of the hammer head. The scraper ring is used to remove and clean the soil around the hammer head, preventing it from reducing impact force and hindering the hammer's crushing effect.

[0009] According to the above technical solution, the adjusting device further includes an elastic block and a semi-cylinder. The elastic block is fixed on the top surface of the scraper ring, and the semi-cylinder is fixed on the outer wall of the hammer head of the oil hammer. The elastic block is located on the movement trajectory of the oil hammer. When the hammer head is hammering, the hammer head drives the semi-cylinder to move up and down. During the up and down movement, the semi-cylinder repeatedly squeezes the elastic block, and the elastic block repeatedly hits the outer wall of the hammer head, causing the stones adhering to the bottom of the hammer head to fall off, avoiding the stones from causing the hammer head to tilt at the hammering angle, and further reducing the risk of the oil hammer causing the device to tip over due to the hammering angle.

[0010] According to the above technical solution, the ranging device includes a folding plate, a second telescopic plate, a first scale, a square plate, a vibration damping rod, a support rod, and a second scale. One end of the folding plate is hinged to the outer wall of the middle part of the hydraulic hammer, and the other end of the folding plate is hinged to the inner wall of the sliding frame. The second telescopic plate is slidably installed on the inner wall of the sliding frame and is located on the movement trajectory of the folding plate. The first scale is fixed to the top surface of the second telescopic plate, the square plate is fixed to the inner wall of the sliding frame, the top end of the vibration damping rod is fixed to the bottom surface of the square plate, and the bottom end of the vibration damping rod is fixed to the top surface of the second telescopic plate. One end of the support rod is hinged to the top of the hydraulic hammer, and the second scale is hinged to the other end of the support rod. The second scale is slidably installed on the front of the vertical slide rail. With a protective cover installed, the operation of the adjusting device is obstructed, making it difficult for the operator. Understanding the specific internal positioning details makes secondary positioning ineffective. Therefore, when the hydraulic hammer moves, it presses against the folding plate, causing the folding plate to fold upwards. The folding plate then pushes the telescopic plate two upwards, which in turn pushes the scale one upwards. The height of the scale one protruding from the protective cover is used to quantitatively observe the lateral distance of the hydraulic hammer. Simultaneously, the square plate and vibration damping rod prevent the telescopic plate two from violently moving up and down due to inertia during hydraulic hammer operation, thus avoiding impacts on the internal structure. When adjusting the front-to-back positioning of the hydraulic hammer, the hammer pushes and pulls the support rod, which in turn pushes and pulls the scale two. The change in the height of the scale two allows for quantitative observation of the front-to-back positioning of the hydraulic hammer. This enables operators outside the protective cover to observe and measure the status of the adjustment device, resulting in more accurate positioning.

[0011] According to the above technical solution, the ranging device further includes a connecting block, a concentric frame, a base block, and a rotating cylinder. One end of the connecting block is fixed to the inner wall of the sliding frame, and the concentric frame is fixed to the other end of the connecting block. The base block is slidably installed on the inner wall of the concentric frame, and the rotating cylinder is rotatably installed inside the base block. A spring is provided between the base block and the inner wall of the concentric frame. Because the scale is very long, the vibration generated during the operation of the hydraulic hammer may damage the scale. The connecting block and the concentric frame limit the scale, the rotating cylinder ensures smooth up and down movement of the scale, and the spring between the base block and the inner wall of the concentric frame protects and dampens the slight swaying of the scale, thereby achieving the purpose of protecting the scale and preventing it from breaking.

[0012] According to the above technical solution, the anti-jamming device includes an elastic rod, a long plate, a rebound column, a trapezoidal block, a concentric circle block, and a triangular block. A vertical square groove is formed on the inner wall of the vertical slide rail. The elastic rod is fixed to the inner wall of the vertical square groove. The long plate is fixed to the telescopic end of the elastic rod. One end of the rebound column is fixed to the top surface of the telescopic slider. The trapezoidal block is fixed to the other end of the rebound column. The concentric circle block is fixed to the bottom surface of the trapezoidal block. The triangular block is slidably mounted on the top surface of the telescopic slider. The triangular block is located on the movement trajectory of the concentric circle block. The long plate is located on the movement trajectory of the triangular block. When the hydraulic hammer is in use, in addition to the movement of the hammer head, the rebound force from the impact also causes the hydraulic hammer to move up and down to a certain extent. The telescopic slider slides within the track of the vertical slide rail. The limiting position of the telescopic slider and the vertical slide rail is... The reason why the hydraulic hammer can hit the same target every time it falls is that it can also absorb energy from the rebound of the hydraulic hammer. During the up and down movement of the telescopic slider, stones often splash into the slide rail, causing the telescopic slider to get stuck and unable to slide normally. This will affect the fall of the hydraulic hammer. When a stone gets stuck in the vertical slide rail, the stone will first squeeze the inclined surface of the trapezoidal block, the trapezoidal block will squeeze the rebound column, the trapezoidal block will drive the concentric block to move downward, the concentric block will squeeze and push the triangular block, the triangular block will squeeze and push the long plate, causing the long plate to retract. The long plate will push the elastic rod to contract. Because of the retraction of the long plate, the vertical slide rail expands, the compression of the stone will disappear, the rebound column will rebound, the rebound column will push the trapezoidal block to move upward, the trapezoidal block will push the stone out of the track, thus clearing the stone and preventing the track from getting stuck.

[0013] According to the above technical solution, the anti-jamming device also includes a rotating rod and a spring plate. The trapezoidal block has an indented square groove on its inclined surface. The rotating rod is fixed to the inner wall of the indented square groove. The spring plate is rotatably installed on the outer wall of the rotating rod. A spring is provided between the spring plate and the inner wall of the indented square groove. When the trapezoidal block pushes the stone out, although the trapezoidal block contacts the stone on an inclined surface, the stone may still be thrown upwards and re-jammed into the track. Therefore, by using the combination of the rotating rod and the spring plate, the spring plate rotates under the action of the spring force. The spring plate provides an outward force to the stone, ensuring that the force angle of the stone is outward and ensuring the effect of throwing the stone.

[0014] This invention provides a support device for a hydraulic hammer. It has the following beneficial effects:

[0015] (1) The present invention, through the setting of the protective device, enables the protective cover, supporting feet, hydraulic spring rod and supporting block to cooperate. The protective cover set on the outside blocks the flying stones. When the oil hammer tilts due to impact, the supporting feet increase the contact area between the device and the bottom surface, improving stability. When the oil hammer tilts, the protective cover squeezes the hydraulic spring rod. The hydraulic spring rod and the supporting block cooperate to absorb the kinetic energy generated by the tilt and rebound the device to straighten it, which greatly improves the anti-tipping effect of the device. The long frame, hydraulic push rod and extension base plate cooperate to start the hydraulic push rod. The hydraulic push rod pushes the extension base plate and uses the extension base plate to fill the gap between the supporting feet and the ground, so that the whole device can maintain a horizontal working state, thereby avoiding the occurrence of tilting accidents.

[0016] (2) The present invention adjusts the setting of the device so that the telescopic slider, sliding frame, telescopic rod, connecting plate, telescopic plate, scraper ring and push plate cooperate. The telescopic slider pushes the sliding frame, and the sliding frame pushes the oil hammer, thereby achieving the purpose of adjusting the front and rear positioning of the oil hammer. Then, the telescopic rod is activated, and the telescopic rod pushes the oil hammer to move left and right, thereby achieving the purpose of adjusting the left and right positioning of the oil hammer. This not only allows for secondary positioning after the device is placed, but also expands the construction range. Furthermore, the scraper ring is used to scrape and clean the soil around the hammer head, avoiding soil adhesion that reduces the impact force of the hammer head and makes the hammer head's crushing effect poor. The elastic block and the semi-cylinder cooperate, and the semi-cylinder repeatedly squeezes the elastic block during the up and down movement. The elastic block repeatedly hits the outer wall of the hammer head, causing the stones adhering to the bottom of the hammer head to fall off, avoiding the stones causing the hammer head to tilt at the striking angle, and further reducing the risk of the device tipping over due to the striking angle of the oil hammer.

[0017] (3) The present invention, through the setting of the distance measuring device, enables the folding plate, the telescopic plate II, the scale I, the square plate, the vibration damping rod, the support rod and the scale II to cooperate. The folding plate pushes the telescopic plate II to move upward, and the telescopic plate II pushes the scale I to move upward. The height of the scale I protruding from the protective cover is used to make actual quantitative observation of the left and right distance of the oil hammer. At the same time, the oil hammer pushes and pulls the support rod, and the support rod pushes and pulls the scale II. The front and rear positioning of the oil hammer is made quantitatively observed according to the height change of the scale II. This allows the operator to observe and measure the state of the adjustment device even outside the protective cover, making the positioning more accurate. The connecting block, the concentric square frame, the bottom block and the rotating cylinder cooperate. The connecting block and the concentric square frame limit the scale I. The rotating cylinder ensures the smooth up and down movement of the scale I. The spring between the bottom block and the inner wall of the concentric square frame protects and dampens the slight shaking of the scale I, thereby achieving the purpose of protecting the scale I and preventing the scale I from breaking.

[0018] (4) The present invention, through the setting of the anti-jamming device, makes the elastic rod, long plate, rebound column, trapezoidal block, concentric circle block and triangular block cooperate. When a stone gets stuck in the vertical slide rail, the stone will first squeeze the inclined surface of the trapezoidal block, the trapezoidal block squeezes the rebound column, the trapezoidal block drives the concentric circle block to move downward, the concentric circle block squeezes and pushes the triangular block, the triangular block squeezes and pushes the long plate, causing the long plate to retract. The long plate pushes the elastic rod to contract. Because of the retraction of the long plate, the vertical slide rail expands, so the compression of the stone disappears, the rebound column rebounds, the rebound column pushes the trapezoidal block to move upward, and the trapezoidal block pushes the stone out of the track, achieving the purpose of clearing the stone and avoiding track jamming; the rotating rod and the spring plate cooperate. With the cooperation of the rotating rod and the spring plate, the spring plate rotates under the action of spring force. The spring plate provides an outward force to the stone, ensuring that the force angle of the stone is outward, ensuring the effect of throwing the stone. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figure 1-5 One embodiment of the present invention is a support device for a hydraulic hammer, including a hydraulic hammer 11, a vertical slide rail 12 provided on the back of the hydraulic hammer 11, and a protective device 2, an adjusting device 3, a ranging device 4, and an anti-jamming device 5 provided on the outside of the hydraulic hammer 11. The protective device 2 includes a protective cover 21, a supporting foot 22, a hydraulic spring rod 23, and a supporting block 24. The inner wall of the protective cover 21 is fixed to the back of the vertical slide rail 12. In engineering environments, when hydraulic hammers are used, the impact pressure often causes ground stones to break, resulting in some stone fragments flying out. Stone fragments hitting people can easily cause injuries, and during the impact process, the hydraulic hammer can easily tilt and collapse, causing more serious safety accidents. Therefore, When the hydraulic hammer 11 is in operation, the protective cover 21 set on the outside is used to block the flying stones. The support foot 22 is fixed to the bottom of the outer wall of the protective cover 21. When the hydraulic hammer 11 tilts due to impact, the support foot 22 increases the contact area between the device and the bottom surface, improving stability. The top of the hydraulic spring rod 23 is hinged to the outside of the support foot 22, and the support block 24 is hinged to the bottom of the hydraulic spring rod 23. When the hydraulic hammer 11 tilts, the hydraulic hammer 11 drives the vertical slide rail 12 to tilt, and the vertical slide rail 12 drives the protective cover 21 to tilt. The protective cover 21 squeezes the hydraulic spring rod 23. The hydraulic spring rod 23 and the support block 24 work together to absorb the kinetic energy generated by the tilt and rebound the device to straighten it, which greatly improves the anti-tipping effect of the device.

[0031] The protective device 2 also includes a long frame 25, a hydraulic push rod 26, and an extension base plate 27. The long frame 25 is fixed to the top of the support foot 22, and the hydraulic push rod 26 is fixed to the bottom of the long frame 25. Before placing the hydraulic hammer 11 and the protective cover 21, the ground generally needs to be leveled to a certain extent. Uneven ground may prevent the device from being deployed. When there is a slight level difference in the ground, the hydraulic push rod 26 can be activated. The telescopic end of the hydraulic push rod 26 passes through the top surface of the support foot 22, and the extension base plate 27 is fixed to the telescopic end of the hydraulic push rod 26. The hydraulic push rod 26 pushes the extension base plate 27, using the extension base plate 27 to fill the gap between the support foot 22 and the ground, so that the entire device can maintain a horizontal working state, thereby avoiding the occurrence of tilting accidents.

[0032] The adjusting device 3 includes a telescopic slider 31, a sliding frame 32, a telescopic rod 33, a connecting plate 34, a telescopic plate 35, a scraper ring 36, and a push plate 37. The telescopic slider 31 is slidably installed on the inner wall of the vertical slide rail 12. Due to the protective cover 21, the hydraulic hammer 11 may not be accurately positioned at the work site when placed there. Therefore, the telescopic slider 31 can be activated. The sliding frame 32 is fixed to the telescopic end of the telescopic slider 31. The telescopic slider 31 pushes the sliding frame 32, and the sliding frame 32 pushes the hydraulic hammer 11, thereby adjusting the front-to-back positioning of the hydraulic hammer 11. The telescopic rod 33 is fixed to both sides of the inner wall of the sliding frame 32. The telescopic rod 33 is then activated. The telescopic end of the telescopic rod 33 is fixed to both sides of the hydraulic hammer 11. The telescopic rod 33 pushes the hydraulic hammer 11 to move left and right, thereby adjusting the left-to-right positioning of the hydraulic hammer 11, allowing the hydraulic hammer 11 to move within the protective cover 21. It can be used for secondary positioning after the device is placed, and can also expand the construction range to carry out construction outside the fixed point. The connecting plate 34 is fixed to the bottom of the sliding frame 32, the telescopic plate 35 is fixed to the bottom of the connecting plate 34, the scraper ring 36 is fixed to the side of the telescopic plate 35 away from the connecting plate 34, and the push plate 37 is fixed to the top surface of the telescopic end of the telescopic plate 35. The push plate 37 is located on the movement trajectory of the hydraulic hammer 11. When the hydraulic hammer 11 adjusts its position, the hydraulic hammer 11 pushes the push plate 37, the push plate 37 pushes the telescopic plate 35 to retract the telescopic plate 35, and the telescopic plate 35 pulls the scraper ring 36, so that the scraper ring 36 and the hammer head keep moving synchronously. When the hydraulic hammer 11 is working, some soil and stones may adhere to the bottom and around the hammer head. The scraper ring 36 is used to scrape and clean the soil around the hammer head to avoid the soil adhesion causing the hammer head's impact force to decrease, resulting in poor hammer head crushing effect.

[0033] The adjusting device 3 also includes an elastic block 38 and a semi-cylinder 39. The elastic block 38 is fixed to the top surface of the scraper ring 36, and the semi-cylinder 39 is fixed to the outer wall of the hammer head of the oil hammer 11. When the hammer head is hammering, the hammer head drives the semi-cylinder 39 to move up and down. The elastic block 38 is located on the movement trajectory of the oil hammer 11. During the up and down movement, the semi-cylinder 39 repeatedly squeezes the elastic block 38, and the elastic block 38 repeatedly hits the outer wall of the hammer head, causing the stones adhering to the bottom of the hammer head to fall off, avoiding the stones from causing the hammer head to tilt at the hammering angle, and further reducing the risk of the oil hammer 11 tipping over due to the hammering angle.

[0034] In engineering environments, hydraulic hammers often break ground rocks due to impact pressure, causing some fragments to fly out. These fragments can easily injure people and can also cause the hammer to tilt and collapse, leading to more serious accidents. Therefore, when the hydraulic hammer 11 is in operation, an external protective cover 21 is used to block the flying rocks. Simultaneously, when the hydraulic hammer 11 tilts due to impact, the support legs 22 increase the contact area between the device and the ground, improving stability. Furthermore, when the hydraulic hammer 11 tilts, it causes the vertical slide rail 12 to tilt, which in turn causes the protective cover 21 to tilt. 1. When tilted, the protective cover 21 compresses the hydraulic spring rod 23. The hydraulic spring rod 23 and the support block 24 work together to absorb the kinetic energy generated by the tilt and rebound the device to straighten it, which greatly improves the anti-tipping effect of the device. Before the oil hammer 11 and the protective cover 21 are placed, the ground generally needs to be leveled to a certain extent. Uneven ground may prevent the device from being deployed. When there is a slight level difference in the ground, the hydraulic push rod 26 can be activated. The hydraulic push rod 26 pushes the extension base plate 27 and uses the extension base plate 27 to fill the gap between the support foot 22 and the ground, so that the entire device can maintain a horizontal working state, thereby avoiding the occurrence of tilting accidents.

[0035] Because of the protective cover 21, the hydraulic hammer 11 may not be accurately positioned when placed at the work site. Therefore, the telescopic slider 31 can be activated, which pushes the sliding frame 32, which in turn pushes the hydraulic hammer 11, thus adjusting the front-to-back positioning of the hydraulic hammer 11. Then, the telescopic rod 33 is activated, which moves the hydraulic hammer 11 left-to-right, thus adjusting its left-to-right positioning. This allows the hydraulic hammer 11 to move within the protective cover 21, enabling secondary positioning after installation and expanding the construction area beyond the fixed-point location. When the hydraulic hammer 11 is adjusted, it pushes the push plate 37, which in turn pushes the telescopic plate 35, causing it to retract. The telescopic plate 35 pulls the scraper ring 36, ensuring synchronous movement between the scraper ring 36 and the hammer head. During operation, some soil and stones may adhere to the bottom and sides of the hammer head; these are removed by scraping. Ring 36 scrapes and cleans the soil around the hammer head to prevent soil adhesion from reducing the impact force of the hammer head and resulting in poor crushing effect. At the same time, when the hammer head is hammering, the hammer head drives the semi-cylinder 39 to move up and down. During the up and down movement, the semi-cylinder 39 repeatedly squeezes the elastic block 38. The elastic block 38 repeatedly hits the outer wall of the hammer head, causing the stones adhering to the bottom of the hammer head to fall off. This prevents the stones from causing the hammer head to tilt at the hammering angle, further reducing the risk of the device tipping over due to the hammer 11 hitting angle.

[0036] Please see Figure 1-9 Based on the above embodiments, another embodiment of the present invention further includes a ranging device 4 and an anti-jamming device 5.

[0037] The ranging device 4 includes a folding plate 41, a second telescopic plate 42, a first scale 43, a square plate 44, a vibration damping rod 45, a support rod 46, and a second scale 47. One end of the folding plate 41 is hinged to the outer wall of the middle part of the hydraulic hammer 11, and the other end of the folding plate 41 is hinged to the inner wall of the sliding frame 32. With the protective cover 21 installed, the operation of the adjusting device 3 will be obstructed, making it difficult for the operator to understand the specific internal positioning, resulting in poor secondary positioning effect. Therefore, when the hydraulic hammer 11 moves, the hydraulic hammer 11 presses the folding plate 41, and the folding plate 41 is pressed and folded upward. The second telescopic plate 42 is slidably installed on the inner wall of the sliding frame 32. The second telescopic plate 42 is located on the movement trajectory of the folding plate 41. The folding plate 41 pushes the second telescopic plate 42 to move upward. The first scale 43 is fixed to the top surface of the second telescopic plate 42. The second telescopic plate 42 pushes the first scale 43 to move upward, utilizing the protrusion of the first scale 43 from the protective cover 21. The height of the hydraulic hammer 11 is quantitatively observed. The square plate 44 is fixed to the inner wall of the sliding frame 32. The top of the vibration damping rod 45 is fixed to the bottom surface of the square plate 44, and the bottom of the vibration damping rod 45 is fixed to the top surface of the telescopic plate 42. The square plate 44 and the vibration damping rod 45 prevent the telescopic plate 42 from moving violently up and down due to inertia when the hydraulic hammer 11 is working, thus avoiding the telescopic plate 42 from hitting the internal structure. One end of the support rod 46 is hinged to the top of the hydraulic hammer 11. When adjusting the front and rear positioning of the hydraulic hammer 11, the hydraulic hammer 11 pushes and pulls the support rod 46. The scale 47 is hinged to the other end of the support rod 46. The support rod 46 pushes and pulls the scale 47. The scale 47 is slidably installed on the front of the vertical slide rail 12. The front and rear positioning of the hydraulic hammer 11 is quantitatively observed according to the height change of the scale 47, so that the operator can observe and measure the status of the adjustment device 3 even outside the protective cover 21, making the positioning more accurate.

[0038] The ranging device 4 also includes a connecting block 48, a concentric square frame 49, a base block 410, and a rotating cylinder 411. One end of the connecting block 48 is fixed to the inner wall of the sliding frame 32, and the concentric square frame 49 is fixed to the other end of the connecting block 48. Because the scale 43 is very long, the vibration generated during the operation of the oil hammer 11 may damage the scale 43. The connecting block 48 and the concentric square frame 49 are used to limit the scale 43. The base block 410 is slidably installed on the inner wall of the concentric square frame 49, and the rotating cylinder 411 is rotatably installed on the inner side of the base block 410. The rotating cylinder 411 is used to ensure the smooth up and down movement of the scale 43. A spring is provided between the base block 410 and the inner wall of the concentric square frame 49. The spring between the base block 410 and the inner wall of the concentric square frame 49 is used to protect and dampen the slight shaking of the scale 43, thereby achieving the purpose of protecting the scale 43 and preventing the scale 43 from breaking.

[0039] The anti-jamming device 5 includes an elastic rod 51, a long plate 52, a rebound post 53, a trapezoidal block 54, a concentric block 55, and a triangular block 56. A vertical square groove is formed on the inner wall of the vertical slide rail 12. The elastic rod 51 is fixed to the inner wall of the vertical square groove. The long plate 52 is fixed to the telescopic end of the elastic rod 51. One end of the rebound post 53 is fixed to the top surface of the telescopic slider 31, and the trapezoidal block 54 is fixed to the other end of the rebound post 53. When the hydraulic hammer 11 is in use, in addition to the movement of the hammer head, the rebound force from the impact also causes the hydraulic hammer 11 to move up and down to a certain extent. The telescopic slider 31 moves along the vertical slide rail 12... The sliding within the track, the limiting of the telescopic slider 31 and the vertical slide rail 12, is the reason why the hydraulic hammer 11 can hit the same target every time it falls, and it can also absorb the energy of the rebound of the hydraulic hammer. However, during the up and down movement of the telescopic slider 31, flying stones often get stuck in the slide rail, causing the telescopic slider 31 to be stuck and unable to slide normally. This will affect the fall of the hydraulic hammer. When a stone gets stuck in the vertical slide rail 12... Inside the track, the stone first presses against the inclined surface of the trapezoidal block 54, which in turn presses against the rebound post 53. The concentric block 55 is fixed to the bottom surface of the trapezoidal block 54, and the trapezoidal block 54 drives the concentric block 55 to move downwards. The triangular block 56 is slidably mounted on the top surface of the telescopic slider 31 and is located on the movement trajectory of the concentric block 55. The concentric block 55 presses against and pushes the triangular block 56, and the long plate 52 is located on the movement trajectory of the triangular block 56. The triangular block 56 presses against and pushes the long plate 52, causing the long plate 52 to retract. The long plate 52 pushes the elastic rod 51 to contract. Because of the retraction of the long plate 52, the vertical slide rail 12 expands, causing the stone's pressure to disappear. The rebound post 53 rebounds and pushes the trapezoidal block 54 upwards. The trapezoidal block 54 pushes the stone out of the track, achieving the purpose of clearing the stone and preventing the track from getting stuck.

[0040] The anti-jamming device 5 also includes a rotating rod 57 and a spring plate 58. The trapezoidal block 54 has a recessed square groove on its inclined surface. The rotating rod 57 is fixed to the inner wall of the recessed square groove. The spring plate 58 is rotatably installed on the outer wall of the rotating rod 57. A spring is provided between the spring plate 58 and the inner wall of the recessed square groove. When the trapezoidal block 54 pushes the stone out, although the trapezoidal block 54 contacts the stone on an inclined surface, the stone may still be thrown upwards and re-jammed into the track. Therefore, by using the cooperation of the rotating rod 57 and the spring plate 58, the spring plate 58 rotates under the action of the spring force. The spring plate 58 provides an outward force to the stone, ensuring that the force angle of the stone is outward and ensuring the effect of throwing the stone.

[0041] When in use, with the protective cover 21 in place, the adjustment device 3 will have its view obstructed, making it difficult for the operator to understand the specific internal positioning, resulting in poor secondary positioning. Therefore, when the hydraulic hammer 11 moves, it presses against the folding plate 41, causing the folding plate 41 to fold upwards. The folding plate 41 pushes the telescopic plate 42 upwards, which in turn pushes the scale 43 upwards. The height of the scale 43 protruding from the protective cover 21 is used to quantitatively observe the left and right distance of the hydraulic hammer 11. At the same time, the square plate 44 and the vibration damping rod 45 prevent the telescopic plate 42 from moving violently up and down due to inertia during the operation of the hydraulic hammer 11, thus avoiding the telescopic plate 42 from impacting the internal structure. When adjusting the hydraulic... When positioning the hammer 11 forward and backward, the hammer 11 pushes and pulls the support rod 46, and the support rod 46 pushes and pulls the scale 47. The forward and backward positioning of the hammer 11 is quantitatively observed based on the height change of the scale 47, so that the operator can observe and measure the status of the adjustment device 3 even outside the protective cover 21, making the positioning more accurate. Because the scale 43 is very long, the vibration generated during the operation of the hammer 11 may damage the scale 43. The connecting block 48 and the concentric square frame 49 are used to limit the scale 43. The rotating cylinder 411 is used to ensure the smooth up and down movement of the scale 43. The spring between the bottom block 410 and the inner wall of the concentric square frame 49 is used to protect and dampen the slight shaking of the scale 43, thereby achieving the purpose of protecting the scale 43 and preventing the scale 43 from breaking.

[0042] When the hydraulic hammer 11 is in use, in addition to the movement of the hammer head, the rebound force from the impact also causes the hydraulic hammer 11 to move up and down to a certain extent. The telescopic slider 31 slides within the track of the vertical slide rail 12. The limiting of the telescopic slider 31 and the vertical slide rail 12 is the reason why the hydraulic hammer 11 can hit the same target every time it falls, and it can also absorb the energy of the rebound of the hydraulic hammer. However, during the up and down movement of the telescopic slider 31, flying stones often get stuck in the slide rail, causing the telescopic slider 31 to be stuck and unable to slide normally. This will affect the fall of the hydraulic hammer. When a stone gets stuck in the vertical slide rail 12 Within the track, the stone first presses against the inclined surface of trapezoidal block 54, which in turn presses against the rebound post 53. Trapezoidal block 54 then moves concentric block 55 downwards, which in turn presses against and pushes triangular block 56. Triangular block 56 presses against and pushes long plate 52, causing long plate 52 to retract. Long plate 52 then pushes elastic rod 51 to contract. Because of the retraction of long plate 52, the vertical slide rail 12 expands, causing the stone's pressure to disappear. The rebound post 53 then rebounds, pushing the trapezoidal block 54... 4. Moving upwards, trapezoidal block 54 pushes the stone out of the track, achieving the purpose of clearing the stone and preventing the track from getting stuck. At the same time, when trapezoidal block 54 pushes the stone out, although trapezoidal block 54 contacts the stone at an angle, the stone may still be thrown upwards and get stuck back into the track. Therefore, by using the cooperation of rotating rod 57 and spring plate 58, the spring plate 58 rotates under the action of spring force, and the spring plate 58 provides an outward force to the stone, ensuring that the force angle of the stone is outward, ensuring the effect of throwing the stone.
