Description

Technical Field

[0001] The invention relates to the field of crushing technology, and in particular to a stone crushing device for bridge and tunnel construction. Background Art

[0002] During the construction of bridges and tunnels, a large number of stones will be generated. Since the stones are of different sizes and some are large in size, they are inconvenient to transport and need to be crushed.

[0003] Choosing the right crushing equipment is crucial to improving construction efficiency and reducing costs. Jaw crushers are generally used for the initial crushing of stones, which can handle large stones with higher hardness. However, there are still the following problems in actual projects: (1) Since water is sprayed during the cutting or dust removal operation, the stones to be crushed are relatively wet, forming wet materials. The wet materials are easily adhered to the inner wall of the crushing chamber, resulting in a reduction in the crushing space and affecting the fluidity of the materials, causing blockage. At the same time, due to the adhesion of the materials, the friction between the movable jaw and the fixed jaw increases, requiring the motor to have a greater power to drive the equipment, thereby increasing energy consumption. If there is a large amount of adhered wet material in the crushing chamber at startup, the starting current will also increase accordingly. The adhered materials may be mixed with hard particles, causing additional wear on the jaw plate and other key components. Therefore, regular manual cleaning is required, which increases maintenance and operating costs.

[0004] (2) For larger stones, it is easy for the stone and the jaw plate to slip, which requires manual handling or the addition of hammering equipment. Manual handling is unsafe, and the addition of hammering equipment is cumbersome and costly because the hammering equipment is large in size and requires manual adjustment of the hammering position.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] Example 1 like Figure 1 As shown, a stone crushing device for bridge and tunnel construction includes a frame 1 and a control terminal. A jaw crushing mechanism 2 and a crushing drive mechanism 3 are arranged on the frame 1. The crushing drive mechanism 3 is connected to the jaw crushing mechanism 2. The crushing drive mechanism 3 includes a crushing drive motor 31 installed on the frame 1. The crushing drive motor 31 is connected to a pulley 32 through a belt. The pulley 32 is connected to an eccentric shaft 33 on the frame 1. The jaw crushing mechanism 2 includes a jaw plate, and the jaw plate includes a fixed jaw plate 21 and a movable jaw plate 22. The fixed jaw plate 21 is installed on the frame 1 through an adjustment component. The adjustment component adopts the existing structure without improvement, and the specific structure is not limited here. The movable jaw plate 22 is arranged opposite to the fixed jaw plate 21 and is connected to the eccentric shaft 33. The crushing drive motor 31 is electrically connected to the control terminal for regulating the operation of the crushing drive motor 31.

[0024] A cleaning mechanism 4 is provided inside the jaw plate. Figure 2 - Figure 3 As shown, the cleaning mechanism 4 includes a clearing unit 41 for clearing adhesive materials and a skipping stone unit 42. The clearing unit 41 for clearing adhesive materials includes a scraper plate 411. The scraper plate 411 is connected to an extension drive hydraulic cylinder 412. The extension drive hydraulic cylinder 412 is electrically connected to the control terminal and is used to drive the scraper plate 411 to move along the jaw plate. The bottom of the scraper plate 411 is provided with a telescopic adapting bottom. The telescopic adapting bottom includes a telescopic plate 413 and a flexible scraper strip 414 (rubber material) arranged on the bottom side of the telescopic plate 413. The flexible scraper strip 414 is adapted to the jaw plate so that the flexible scraper strip 414 fits the jaw plate, which is convenient for scraping the adhesive materials on the jaw plate. The top side of the telescopic plate 413 is connected to a telescopic drive telescopic rod 415. The telescopic drive telescopic rod 415 is arranged on the scraper plate 411. The telescopic drive telescopic rod 415 is electrically connected to the control terminal and is used to adjust the positions of the telescopic plate 413 and the flexible scraper strip 414.

[0025] The telescopic part of the telescopic drive telescopic rod 415 is provided with an engagement groove, which is engaged with the transmission gear 416 in the scraper plate 411, and the transmission gear 416 is engaged with the lifting rack 417 slidably arranged inside the scraper plate 411, and the top of the lifting rack 417 is connected with a baffle plate 418, so as to realize the synchronous movement of the flexible scraper strip 414 and the baffle plate 418. The scraper plate 411 is provided with a material removal mechanism 5, which includes an L-connecting plate 51 installed on both sides of the baffle plate 418, and a material removal plate 52 is connected between the two L-connecting plates 51, and the material removal plate 52 is arranged opposite to the scraper plate 411.

[0026] When the jaw plate needs to be cleaned, the feeding equipment stops feeding. When there is no material in the crushing chamber between the fixed jaw plate 21 and the movable jaw plate 22, the extension drive hydraulic cylinder 412 is started to make the scraper plate 411 move along the jaw plate, and the baffle plate 418 and the flexible scraper strip 414 are in an extended state, so that the material adhering to the jaw plate is scraped off. When it reaches the bottom of the jaw plate, the telescopic drive telescopic rod 415 is started to contract, so that the flexible scraper strip 414 and the baffle plate 418 are retracted into the scraper plate 411 at the same time, so that the material adhering to the flexible scraper strip 414 and the baffle plate 418 is also scraped off by the edge of the scraper plate 411. At the same time, during the descending process of the baffle plate 418, the material removal plate 52 further scrapes the material on the scraper plate 411, thereby realizing the removal of the material adhering to the jaw plate. At the same time, no material will remain on the scraper plate 411, which will not affect the next cleaning, and the cleaning efficiency is high.

[0027] Since stones vary in shape and size, sometimes they are too large or have a smooth surface, so they are prone to jumping in the crushing chamber, causing the subsequent materials to be unable to be crushed. In this embodiment, a jumping stone unit 42 is provided. The jumping stone unit 42 includes a plurality of delivery components arranged on the scraper plate 411. The delivery components are connected with anti-skid teeth 422 (the material is the same as the jaw plate or the material with the same hardness as the jaw plate) for increasing the friction between the stone and the jaw plate.

[0028] The delivery component includes a winch 421 arranged in a protective cover 423 on the back of the scraper blade. The wire rope of the winch 421 passes through the protective cover 423 and the wire ring 424 in turn and is connected to the anti-slip tooth 422. The guide ring is installed on the protective cover 423. The first distance sensor 425 is installed on the guide ring. The anti-slip tooth 422 is arranged on one side of the material baffle plate 418. The front end of the anti-slip tooth 422 is triangular, and the rear end of the anti-slip tooth 422 is cylindrical and fixedly connected to the wire rope; the winch 421 and the first distance sensor 425 are both electrically connected to the control terminal, and the delivery amount of the corresponding winch 421 is calculated according to the distance data of the first distance sensor 425.

[0029] When the bouncing stone occurs, the telescopic driving rod 415 is started to contract, so that the flexible scraper strip 414 and the baffle plate 418 are simultaneously retracted into the scraper plate 411, and the approximate position of the bouncing stone is determined by the distance data of the first distance sensor 425. When the distance of the bouncing stone is greater than or equal to the maximum delivery amount of the winch 421, the position of the scraper plate 411 is adjusted by extending the driving hydraulic cylinder 412, and then the winch 421 is started to deliver the anti-slip teeth 422. When the distance of the bouncing stone is less than the maximum delivery amount of the winch 4 When the maximum delivery amount is 21, the winch 421 is directly started to deliver the anti-skid tooth 422. During the bouncing of the stone, the triangular front end of the anti-skid tooth 422 is inserted between the bouncing stone and the jaw plate, so that the stone does not bounce. At this time, the stone is broken after being subjected to force. After the stone is broken, the winch 421 is started to retract the anti-skid tooth 422, and at the same time, the hydraulic cylinder 412 is extended to return to the initial position, and the flexible scraper strip 414 and the baffle plate 418 return to the extended state to protect the anti-skid tooth 422 and other components.

[0030] Example 2 The difference between this embodiment and embodiment 1 is that an independent hammer mechanism 6 is provided on the top of the jaw crushing mechanism 2. Figure 4 As shown, the independent hammer mechanism 6 adopts an independent driving mode, and the independent hammer mechanism 6 includes a gantry 61, and the gantry 61 is arranged on the top of the jaw crushing mechanism 2 through a first transverse moving module 62, and a first longitudinal moving module 63 and a scanning component 64 are arranged on the gantry 61, and a hammer component 66 is arranged on the first longitudinal moving module 63 through a first height adjustment module 65, and the first transverse moving module 62, the first longitudinal moving module 63, the first height adjustment module 65, the hammer component 66 and the scanning component 64 are all electrically connected to the control terminal.

[0031] The scanning component 64 includes a plurality of linearly distributed second distance sensors and image collectors, both of which are electrically connected to the control terminal. The image collector is used to collect images of stones to determine the shape of the stones, and the second distance sensor is used to collect the height of the second distance sensor above the stone. The scanning component 64 collects the stones stuck in the jaw crushing mechanism 2 to obtain the specific shape and height of the stones. When a large stone is stuck in the crushing chamber, or when the stone-jumping unit 42 cannot fail, the feeding is stopped, the independent hammer mechanism 6 is started, the hammer position is determined according to the specific shape and height of the stone, the position of the hammer assembly 66 is adjusted by the first lateral moving module 62, the first longitudinal moving module 63 and the first height adjustment module 65, and the hammer assembly 66 is started to hammer and crush the stone. During normal crushing, the hammer assembly 66 and the scanning assembly 64 are moved to one side by the first longitudinal moving module 63 to avoid affecting the feeding.

[0032] Example 3 The difference between this embodiment and embodiment 1 is that a linked hammer mechanism 7 is provided on the top of the jaw crushing mechanism 2. Figure 5 - Figure 6 As shown, the linked hammer mechanism 7 includes a guide frame 71, a plurality of guide through holes 711 are provided on the guide frame 71, hammer rods 72 are slidably arranged in the guide through holes 711, one end of the plurality of hammer rods 72 is rotatably connected to a crankshaft 73, the crankshaft 73 is rotatably mounted on the guide frame 71, the guide frame 71 is connected to a camera 75 through an extension rod 74, the camera 75 is arranged opposite to the feed conveying device for collecting stone images. The crankshaft 73 is connected to the crushing drive mechanism 3 through a belt, a tensioning mechanism 8 is arranged on one side of the guide frame 71, the tensioning mechanism 8 includes a tensioning wheel 81, and the tensioning wheel 81 is mounted on one side of the guide frame 71 through a tensioning adjustment telescopic rod 82; a second height adjustment module 76 is connected to the bottom of the guide frame 71, the second height adjustment module 76 is connected to a second lateral adjustment module 77, the second lateral adjustment module 77 is mounted on the frame 1, and the tensioning adjustment telescopic rod 82, the second height adjustment module 76 and the second lateral adjustment module 77 are all electrically connected to the control terminal.

[0033] The specific process is as follows: The camera 75 is electrically connected to the control terminal, and the control terminal analyzes the image collected by the camera 75. When there are stones exceeding the set size, the second lateral adjustment module 77 and the second height adjustment module 76 are activated to move the guide frame 71 to one side and rise. At the same time, the tension adjustment telescopic rod 82 is adjusted according to the movement amount of the second lateral adjustment module 77 and the second height adjustment module 76, so that the belt remains in a tensioned state. When the oversized stone is crushed, the second lateral adjustment module 77 and the second height adjustment module 76 are activated to return the guide frame 71 to the initial position. Compared with Example 2, this embodiment is suitable for the case where the stone is not large. Under the drive of the crushing drive motor 31, the hammer rod 72 hammers the stone while jaw crushing to improve the crushing efficiency.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
