Description

Technical Field

[0001] This invention relates to the field of concrete pavement repair and construction machinery, specifically to a stacked impact crushing device and a high-energy crusher including the device. Background Technology

[0002] Cement concrete pavement structures possess high compressive, flexural, tensile, and abrasion resistance, resulting in excellent durability. They also exhibit good thermal, water, and time stability. Furthermore, they meet high requirements for smoothness and roughness, and require minimal routine maintenance. Based on these advantages, cement concrete pavement is widely used in heavy-duty applications such as highway construction, airport roads, runway construction, and port and dock areas. However, under high loads and natural factors, even high-strength, thick cement concrete pavements will exhibit various deterioration defects (such as cracks, misalignment, slab breaks, edge chipping, voids, and erosion). For safety reasons, high-strength, thick cement concrete pavements are often broken up, excavated, and repaved after reaching their service life or exhibiting deterioration. However, due to the limited thickness of existing crushing equipment, it is difficult to directly crush the entire structure in the thickness direction. The crushing of high-strength, thick cement concrete pavement is generally carried out by using large hydraulic breakers for layered crushing, which results in low construction efficiency. When the construction period is tight, in order to improve the efficiency of operation, a large-scale mechanized construction method is adopted. Although this can speed up the project progress, it will increase the labor intensity of construction workers, significantly increase the overall construction cost, and waste equipment resources. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a stacked impact crushing device and a high-energy crusher including the device, so as to solve the technical problems of low crushing thickness of concrete pavement and low working efficiency of existing crushing equipment when crushing thick concrete pavement.

[0004] To achieve the above and other related objectives, the present invention provides a stacked impact crushing device, comprising: a frame, a crushing device, a stacking device, and a pulling body. The frame is provided with a first lifting assembly having a first movable end extending vertically upwards; the crushing device is slidably disposed within the frame, and its lower end is provided with a crushing blade that can slide out of the bottom of the frame; the stacking device includes a lifting frame, a second lifting assembly, and a lifting wheel assembly; the lifting frame is slidably mounted on the frame and fixedly connected to the first movable end; the second lifting assembly is fixedly mounted on the lifting frame and has a second movable end extending vertically upwards; the lifting wheel assembly is fixedly mounted on the top of the second movable end; one end of the pulling body is fixedly connected to the crushing device, and the other end of the pulling body slides around the lifting wheel assembly and is fixedly connected to the frame; wherein the crushing device and the stacking device slide vertically within the frame.

[0005] In one example of the stacked impact crushing device of the present invention, the first lifting component includes two first hydraulic cylinders, which are respectively disposed on both sides of the stacking device. The first hydraulic cylinder is provided with a first oil supply pipe group. The second lifting component includes a second hydraulic cylinder, which is provided with a second oil supply pipe group. Both the first oil supply pipe group and the second oil supply pipe group include multiple oil supply pipes.

[0006] In one example of the stacked impact crushing device of the present invention, the lifting frame is further provided with two guiding mechanisms. The two guiding mechanisms are located on both sides of the second lifting assembly. Each guiding mechanism includes a guide sleeve and a guide rod. The top ends of the two guide rods are fixedly installed on the lifting wheel assemblies on both sides of the movable end of the second lifting assembly. The bottom ends of the guide rods are slidably installed inside the guide sleeve from the top end of the guide sleeve. The guide sleeve is fixedly installed on the lifting frame.

[0007] In one example of the stacked impact crushing device of the present invention, the frame includes an upper frame and a lower frame, which are rotatably connected. The upper frame and the lower frame are provided with a first slide rail group that cooperates with each other. The crushing device is slidably installed on the first slide rail group. The upper frame is also provided with a second slide rail group, and the stacking device is slidably installed on the second slide rail group. The first lifting component is installed in the upper frame.

[0008] In one example of the stacked impact crushing device of the present invention, the crushing device includes a hammer body, which is slidably mounted on the first slide rail group, and the crushing blade is detachably mounted on the lower end of the hammer body.

[0009] In one example of the stacked impact crushing device of the present invention, the stacked impact crushing device further includes a stabilizing device, which is fixedly installed on one side of the lower frame. The stabilizing device includes a stabilizing arm and an auxiliary wheel. One end of the stabilizing arm is fixedly installed on the outside of the lower frame, and the auxiliary wheel is rotatably installed on the end of the stabilizing arm away from the lower frame. The auxiliary wheel is located on the crushing surface or other base surface.

[0010] In one example of the stacked impact crushing device of the present invention, the lower frame includes an outer frame and an inner frame. The inner frame is fixedly installed inside the outer frame. A shock-absorbing and buffering assembly is provided between the inner frame and the outer frame. The inner frame is provided with a first slide rail assembly that cooperates with the upper frame. The stabilizing arm is fixedly installed on the outside of the outer frame.

[0011] The present invention also provides a high-energy crusher, the crusher including the stacked impact crushing device, and the high-energy crusher further including a traction control device connected to the stacked impact crushing device via a connecting part.

[0012] In one example of the crusher of the present invention, the connecting part includes a tilting component, a connecting component, and a lifting component. The two ends of the tilting component are rotatably connected to the upper frame and the traction control device, respectively. The two ends of the connecting component and the lifting component are rotatably connected to the outer frame and the traction control device, respectively.

Utilizing the principle of a movable pulley, the lifting wheel assembly pulls the crushing device higher via the traction body. The lifting height of the crushing device is twice that of the lifting wheel assembly, allowing the crushing device to acquire greater gravitational potential energy in a shorter time and release it rapidly. This maximizes the kinetic energy of the crushing device when it falls onto the surface to be crushed, thereby achieving one-time crushing of thick concrete pavement in the thickness direction and improving work efficiency.

[0030] Please see Figures 1 to 9This invention provides a stacked impact crushing device and a high-energy crusher including the device. The stacked impact crushing device lifts the lifting frame 310 and the lifting wheel assembly 320 to a certain height through the first lifting assembly 130 and the second lifting assembly 330. Utilizing the principle of movable pulleys, the lifting wheel assembly 320 pulls the crushing device 200 up through the pulling body 400. The lifting height of the crushing device 200 is twice the lifting height of the lifting wheel assembly 320, which allows the crushing device 200 to obtain greater gravitational potential energy. This maximizes the kinetic energy of the crushing device 200 when it falls onto the base surface to be crushed, thereby achieving one-time crushing of thick concrete pavement in the thickness direction and improving work efficiency.

[0031] Please see Figure 1 , Figure 3 and Figure 6 , Figure 1 This is a schematic diagram of the overall structure of the stacked impact crusher and the high-energy crusher including the device in operation according to an embodiment of the present invention. Figure 3 This is a schematic diagram showing the state of the stacking impact crusher and the high-energy crusher including the device in one embodiment of the present invention when the stacking device is raised. Figure 6This is a front view of the crushing device in an embodiment of the stacked impact crushing device and the high-energy crusher including the device according to the present invention. The present invention provides a stacked impact crushing device, comprising: a frame 100, a crushing device 200, a stacking device 300, and a pulling body 400. The material of the frame 100 is not limited, but preferably, the frame 100 should have high structural strength. A first lifting assembly 130 is provided on the frame 100, the first lifting assembly 130 having a first movable end 131 extending upward in a vertical direction; the crushing device 200 is slidably disposed within the frame 100 and can slide up and down vertically on the frame 100; a crushing blade 220 is provided at the lower end of the crushing device 200, and the crushing device 200 can slide out of the bottom end of the frame 100 so that the crushing blade 220 acts on the surface to be crushed. The stacking device 300 includes a lifting frame 310, a second lifting assembly 330, and a lifting wheel assembly 320. The lifting frame 310 is slidably mounted on the frame 100 and fixedly connected to the first movable end 131. Under the action of the first lifting assembly 130, the lifting frame 310 can slide out of the top of the frame 100. The second lifting assembly 330 is fixedly mounted on the lifting frame 310 and has a second movable end 332 extending upward in a vertical direction. The lifting wheel assembly 320 is fixedly mounted on the top of the second movable end 332. The lifting wheel assembly 320 includes a lifting wheel 321 and a rotating shaft 322. The lifting wheel 321 is rotatably mounted on the rotating shaft 322. Both ends of the rotating shaft 322 are fixedly mounted on the top of the guide rod 342, and the middle part of the rotating shaft 322 is fixedly mounted on the top of the second movable end 332. The rotating shaft 322 of the lifting wheel 321 is horizontally positioned. One end of the pulling body 400 is fixedly connected to the crushing device 200, and the other end of the pulling body 400 is fixedly connected to the frame 100, passing around the lifting wheel assembly 320. The pulling body 400 slides in cooperation with the sliding groove of the pulley in the lifting wheel assembly 320. The pulling body 400 includes, but is not limited to, ropes, chains, etc. During operation, the frame 100 is set vertically, and the crushing device 200 and the stacking device 300 slide vertically within the frame 100.

[0032] Please see Figure 3 , Figure 4 and Figure 6 , Figure 4This is a schematic diagram of the initial state of the stacking impact crusher and the high-energy crusher including the device in one embodiment of the present invention. During crushing operations, the first lifting component 130 first lifts the stacking device 300, and then the second lifting component 330 lifts the lifting wheel component 320. During this process, the lifting wheel 321 pulls the crushing device 200 up through the rotating chain. Since one end of the pulling body 400 is fixed, the height to which the crushing device 200 is lifted will reach twice the height to which the lifting wheel component 320 is lifted, so that the crushing device 200 obtains the maximum gravitational potential energy. Then, the lifting action of the first lifting component 130 and the second lifting component 330 is released, so that the crushing device 200 falls under the action of gravity, so that the kinetic energy of the crushing blade 220 is maximized when it touches the surface to be crushed, that is, the crushing effect on the surface to be crushed is maximized.

[0033] Please see Figure 1 and Figure 3 In one example of the stacked impact crushing device of the present invention, the first lifting assembly 130 includes two first hydraulic cylinders, which are symmetrically arranged on both sides of the stacked device 300. Each first hydraulic cylinder is equipped with a first oil supply pipe assembly (not shown, see reference). Figure 3 The second lifting assembly 330 includes a second hydraulic cylinder, on which the second hydraulic cylinder is equipped with the second oil supply pipe group 331. Both the first and second oil supply pipe groups 331 include multiple oil supply pipes 3312. Multiple oil supply pipes 3312 simultaneously supply or discharge oil, thereby enabling rapid extension and retraction of the first and second hydraulic cylinders, shortening the lifting and lowering cycle time of the telescopic crushing device 200, and further improving work efficiency. The number of oil supply pipes 3312 is not limited. If one oil supply pipe 3312 is provided in one oil supply pipe group, then the oil supply pipe 3312 needs to have a sufficiently large inner diameter. However, larger-sized oil supply pipes 3312 have poor bending flexibility. Therefore, in this embodiment, one oil supply pipe group includes multiple oil supply pipes 3312. In this embodiment, both the first and second oil supply pipe groups 331 include four oil supply pipes 3312. Simultaneously, both the inlet and outlet ends of the first and second oil supply pipe groups 331 are equipped with rotary joints 3311 that converge the four corresponding oil supply pipes 3312. The rotary joints 3311 at both ends of each oil supply pipe group are rotatably and sealingly connected to the oil supply device and the corresponding oil cylinder, respectively. When the first and second oil cylinders are operating, the rotation function of the rotary joints 3311 can prevent the oil supply pipes 3312 from bending and affecting the oil supply and unloading speeds, while also reducing the risk of breakage of the oil supply pipes 3312. It should be noted that the connection between the oil supply pipes and the oil cylinders, which is not described in detail, is prior art and will not be elaborated upon further.

[0034] Please see Figure 3In one example of the stacked impact crushing device of the present invention, the lifting frame 310 is further provided with two guide mechanisms 340. The two guide mechanisms 340 are located on both sides of the second lifting assembly 330. The guide mechanisms 340 are used to fix the direction of the rotation shaft 322 of the lifting wheel assembly 320, and prevent the extension rod of the second hydraulic cylinder from rotating with the cylinder body, thereby causing the lifting wheel assembly 320 to rotate. The guide mechanism 340 includes a guide sleeve 341 and a guide rod 342. The top ends of the two guide rods 342 are fixedly installed on the lifting wheel assemblies 320 on both sides of the movable end of the second lifting assembly 330. The bottom ends of the guide rods 342 are slidably installed in the guide sleeve 341 from the top end of the guide sleeve. The guide sleeve 341 is fixedly installed on the lifting frame 310. In this embodiment, to ensure smooth sliding of the guide rod 342 within the guide sleeve 341 and to prevent excessive friction between the inner wall of the guide sleeve 341 and the outer wall of the guide rod 342, which could affect the conversion efficiency of the crushing device 200 from gravitational potential energy to kinetic energy, the side wall of the guide sleeve 341 is also provided with multiple guide wheels 350. These guide wheels 350 are distributed circumferentially around the guide rod 342 and roll along the sliding direction of the guide rod 342. In this embodiment, each guide sleeve 341 is provided with eight guide wheels 350, which are divided into two groups. One group has four guide wheels 350 located at the top of the corresponding guide sleeve 341, evenly distributed circumferentially, with the rolling surface of the guide wheels 350 engaging with the cylindrical side surface of the guide rod 342. The other group has four guide wheels 350 located at the middle of the corresponding guide sleeve 341, also evenly distributed circumferentially. This allows the guide rod 342 to slide within the guide sleeve 341 via the guide wheel 350, reducing sliding resistance and ensuring the efficiency of the conversion of the gravitational potential energy to kinetic energy in the crushing device 200.

[0035] Please see Figure 1 , Figure 3 and Figure 5 , Figure 5 This is a top view of the lower frame in an embodiment of the stacked impact crusher and high-energy crusher including the present invention. In one example of the stacked impact crusher of the present invention, the frame 100 includes an upper frame 110 and a lower frame 120, which are rotatably connected by a connecting shaft 150. The connecting shaft 150 is located on one edge of the connecting surface between the upper frame 110 and the lower frame 120 to prevent interference between the upper frame 110 and the lower frame 120 during rotation and to limit the rotation angle.

[0036] Please see Figure 5In one embodiment of the present invention, the upper frame 110 and the lower frame 120 are provided with a first slide rail assembly that cooperates with each other, and the crushing device 200 is slidably mounted on the first slide rail assembly. In this embodiment, the first slide rail assembly includes two opposing U-shaped slide rails 140, which form a sliding space, thereby restricting the path of the crushing device 200 during its rising and falling process, allowing the crushing device 200 to slide to the surface to be crushed below the lower frame 120. This prevents the crushing device 200 from deviating in its falling direction and exerting impact force on the frame 100, causing equipment damage or even a safety accident. Rollers that cooperate with the U-shaped slide rails 140 may also be provided on the crushing device 200 to increase the smoothness of sliding.

[0037] Please see Figures 2 to 4 In one embodiment of the present invention, a second slide rail assembly is further provided inside the upper frame 110. The stacking device 300 is slidably mounted on the second slide rail assembly, which is located on one side. The second slide rail assembly includes two slide grooves 360, which are arranged opposite to each other. The stacking device 300 slides between the two slide grooves 360 at least partially via pulleys. The top of the stacking device 300 is provided with lifting rods extending to both sides to the outside of the two slide grooves 360 for connecting to the first lifting assembly 130. The first lifting assembly 130 is installed inside the upper frame 110. The two first hydraulic cylinders of the first lifting assembly 130 are respectively located on the side of the two slide grooves 360 away from the stacking device 300. The cylinder body end of the first hydraulic cylinder is fixedly connected to the upper frame 110, and the movable end of the first hydraulic cylinder is fixedly connected to the corresponding end of the lifting rod. To increase the coordination between the first hydraulic cylinder and the upper frame 110 and the stacking device 300, the cylinder end of the first hydraulic cylinder and the upper frame 110, as well as the movable end of the first hydraulic cylinder and the stacking device 300, can be rotatably connected to accommodate reasonable deviations between the positions of the stacking device 300 and the upper frame 110.

[0038] Please see Figure 6 and Figure 7 , Figure 7 This is a side view of the crushing device in one embodiment of the stacked impact crushing device and the high-energy crusher including the device of the present invention. In one example of the stacked impact crushing device of the present invention, the crushing device 200 includes a hammer 210, which is slidably mounted on a first slide rail assembly, and a crushing blade 220 is detachably mounted on the lower end of the hammer 210. Hammers 210 of different weights can be replaced according to different applications. The shape of the crushing blade 220 is not limited; different types of crushing blade heads can be selected according to the crushing surface conditions and crushing requirements. The crushing blade 220 has a small contact area with the surface to be crushed, so that the impact force of the crushing device 200 on the surface to be crushed acts on a smaller range, increasing the crushing depth. At the same time, if the crushing blade 220 is damaged during use, it can be replaced at any time.

[0039] Please see Figure 1, Figure 8 and Figure 9 , Figure 8 This is a side view of a stabilizing device in one embodiment of the stacked impact crusher and the high-energy crusher including the present invention. Figure 9 This is a top view of a stabilizing device in an embodiment of the stacked impact crusher and high-energy crusher including the present invention. In one example of the stacked impact crusher, the device further includes a stabilizing device 500, which is fixedly installed on one side of the lower frame 120. The stabilizing device 500 is used to balance the reaction force of the dispersed crushing device 200 on the frame 100 during operation, ensuring the stability of the frame 100 and preventing problems such as tilting or overturning. The stabilizing device 500 includes a stabilizing arm 510 and an auxiliary wheel 520. One end of the stabilizing arm 510 is fixedly installed on the outside of the lower frame 120, and the auxiliary wheel 520 is rotatably installed on the end of the stabilizing arm 510 away from the lower frame 120. The auxiliary wheel 520 is located on the crushing surface or other base surface. There is at least one stabilizing arm 510, and at least one auxiliary wheel 520 on each stabilizing arm 510. In this embodiment, there are two stabilizing arms 510, and each stabilizing arm 510 is equipped with two auxiliary wheels 520. The included angle and distance between the two stabilizing arms 510 are adjustable. The auxiliary wheels 520 not only serve as stabilizing fulcrums for the stabilizing device 500, but also assist in the movement and transportation of the stacked impact crusher. Since the stacked impact crusher has a large overall mass, it is easy to cause the center of gravity of the traction equipment to shift when moving, especially on uneven roads, which could lead to safety accidents. By using the side of the stacked impact crusher away from the stabilizing device 500 as the traction position, the stabilizing device 500 on the other side can balance the overall center of gravity of the traction equipment and the stacked impact crusher.

[0040] Please see Figure 1 and Figure 5 In one example of the stacked impact crushing device of the present invention, the lower frame 120 includes an outer frame 121 and an inner frame 122. The inner frame 122 is fixedly installed inside the outer frame 121, and a shock-absorbing buffer assembly 123 is provided between the inner frame 122 and the outer frame 121. Dividing the lower frame 120 into an inner frame 122 and an outer frame 121 can increase the shock resistance of the lower frame 120 and reduce rigid damage to the lower frame 120. The shock-absorbing buffer assembly 123 can further absorb the impact energy of the crushing device 200 on the lower frame 120 when it slides in the first slide rail group. The inner frame 122 is provided with a first slide rail group that cooperates with the upper frame 110, and the stabilizing arm 510 is fixedly installed on the outside of the outer frame 121.

[0041] Please see Figure 1 and Figure 2The present invention also provides a high-energy crusher, which includes a stacked impact crushing device and a traction control device 600. The stacked impact crushing device is connected to the traction control device 600 via a connecting part 700. The connecting part 700 is located on the side of the stacked impact crushing device away from the stabilizing device 500, and the traction control device 600 moves the stacked impact crushing device through the connecting part 700. The traction control device 600 includes, but is not limited to, a vehicle. In this embodiment, the traction control device 600 is a tractor.

[0042] Please see Figure 1 and Figure 2 In one example of the crusher of the present invention, the connecting part 700 includes a tilting assembly 710, a connecting assembly 720, and a lifting assembly 730. The two ends of the tilting assembly 710 are rotatably connected to the upper frame 110 and the tractor, respectively. The two ends of the connecting assembly 720 and the lifting assembly 730 are rotatably connected to the outer frame 121 and the tractor, respectively. One end of the tilting assembly 710 is rotatably connected to the upper frame 110, and the other end is rotatably connected to the tractor. One end of the connecting assembly 720 is rotatably connected to the outer frame 121, and the other end is rotatably connected to the tractor. One end of the lifting assembly 730 is rotatably connected to the outer frame 121, and the other end is rotatably connected to the tractor. The tilting assembly 710 includes a tilting cylinder, the two ends of which are rotatably connected to the upper frame 110 and the tractor, respectively. The tilting cylinder controls the rotation of the upper frame 110 and the lower frame 120, and the connecting shaft 150 is located on the side of the frame 100 closest to the tractor. During operation, the tilting cylinder is in the extended state, and the upper frame 110 and the lower frame 120 are in the same vertical plane; during transportation, the tilting cylinder is adjusted to the retracted state, causing the upper frame 110 to tilt towards the tractor, thereby reducing the overall height of the stacked impact crusher and balancing the center of gravity for easier transportation.

[0043] Please see Figure 1 and Figure 2 The lifting assembly 730 includes a lifting cylinder, with both ends rotatably connected to the outer frame 121 and the traction control device 600, respectively. One end of the connecting assembly 720 is rotatably connected to the side of the outer frame 121 away from the stabilizing device 500, and the other end is rotatably connected to the tractor. The connecting assembly 720 includes, but is not limited to, a four-bar linkage mechanism. The connecting assembly 720, through its extension and retraction cooperation with the lifting cylinder, enables the lifting and lowering of the stacked impact crusher. During operation, the stacked impact crusher is adjusted to a suitable height, so that the lower end of the lower frame 120 is a certain distance above the surface to be crushed, allowing the crushing blade 220 to fully act on the surface after falling. During transportation and relocation, the stacked impact crusher is raised to a certain height to increase the departure angle, facilitating transportation, avoiding interference with uneven road surfaces, and increasing ground clearance for easy replacement of the crushing blade 220.

[0044] This invention relates to a stacked impact crushing device and a high-energy crusher including the device. The invention uses a first lifting assembly and a second lifting assembly to raise the lifting frame and lifting wheel assembly to a certain height. Utilizing the principle of a movable pulley, the lifting wheel assembly pulls the crushing device higher via a traction body. The lifting height of the crushing device is twice that of the lifting wheel assembly, allowing the crushing device to acquire greater gravitational potential energy in a shorter time. This maximizes the kinetic energy of the crushing device when it falls onto the surface to be crushed. Simultaneously, the multi-oil pipe arrangement of the oil supply assembly allows for rapid oil supply and unloading of the hydraulic cylinders, thereby increasing the lifting speed of the crushing device and avoiding interference from the hydraulic cylinders during the fall. This enables rapid and effective one-time crushing of thick concrete pavements in the thickness direction, improving work efficiency. Furthermore, the stabilizing device of this invention increases its stability during operation and movement, and the tilting mechanism of the frame facilitates transportation. Therefore, this invention effectively overcomes some practical problems in the prior art, thus having high utilization value and practical significance. The above embodiments are merely illustrative of the principles and effects of the invention and are not intended to limit the invention. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this invention should still be covered by the claims of this invention.
