Description

Technical Field

[0001] This invention relates to the field of diaphragm wall rock trenching technology, specifically to a special equipment for trenching rock entry into diaphragm walls. Background Technology

[0002] Currently, the equipment used for excavating rock into diaphragm walls mainly comes in three forms: First, hydraulic grab buckets: the grab bucket is opened and closed by a hydraulic system, and cuts into the strata under the action of gravity, which can also play a certain role in excavation for softer rock layers; Second, drilling rigs: the weight and impact force of the drill bit are used to break the rock, or the drill bit is rotated by the drill rod, and the cutting edge of the drill bit cuts and breaks the rock during the rotation; Third, milling machines: two milling wheels rotate in opposite directions to mill and break the rock.

[0003] However, of the three types of rock-cutting equipment mentioned above, hydraulic grab buckets are mainly used for cutting softer rock layers, impact drills are suitable for rocks of various hardnesses, especially for hard bedrock such as quartzite and basalt, which have a good rock-cutting effect, rotary drills can take advantage of their high cutting efficiency for some rocks with a certain degree of hardness but not particularly hard, and milling machines are suitable for rock layers with complex geological conditions, such as hard rock and fractured zones.

[0004] As can be seen from the above, different types of rock-cutting equipment can only be used effectively for specific rock layers. However, the rock layers encountered during the excavation of underground walls are subject to uncertainties. Therefore, there is an urgent need for a special rock-cutting equipment that can be applied to all types of rock layers. Summary of the Invention

[0005] The purpose of this invention is to provide a special equipment for trenching into rock for diaphragm walls, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a special equipment for trenching and rock entry in underground continuous wall, comprising a body, a guide mechanism fixedly installed on the lower outer side of the body, a rock entry mechanism one provided on the lower side of the guide mechanism, and a rock entry mechanism two fixedly connected to the inner side of the body through a horizontal plate, wherein the rock entry mechanism two and the rock entry mechanism one are threadedly connected.

[0007] The rock-entry mechanism includes a connecting component and a crushing component. The connecting component is rotatably connected to the lower side of the guide mechanism, and the crushing component is fixedly installed on the inner side of the connecting component.

[0008] The crushing assembly includes a hydraulic breaker, a crushing block, a third hydraulic cylinder, a first piston motor, and a screw rod. The inner side of the connecting assembly is fixedly connected to a uniformly distributed hydraulic breaker. The head of the hydraulic breaker is fixedly connected to a crushing block. The upper inner side of the connecting assembly is fixedly connected to a third hydraulic cylinder. The output end of the third hydraulic cylinder is fixedly connected to a first piston motor. The output end of the first piston motor is fixedly connected to a screw rod.

[0009] Start hydraulic cylinder one, hydraulic cylinder one retracts, thereby driving the motion platform to reset, so that rock entry mechanism one resets, and then the bottom of the fixed shell contacts the rock layer, start hydraulic breaker hammer. Since the hydraulic breaker hammer is set with multiple evenly distributed sets in the fixed shell, the multiple sets of breaking blocks impact the rock layer to break it.

[0010] Through the cooperation between the second rock-entry mechanism and the first rock-entry mechanism, three different rock-entry modes—milling, crushing, and cutting—can be switched.

[0011] When encountering rock layers of moderate hardness, start the plunger motor one. The plunger motor one drives the screw to rotate, so that the rock is cut and broken by cutting force.

[0012] When facing rock layers of varying hardness, it can automatically switch between three modes of rock entry and grooving.

[0013] Furthermore, the guiding mechanism includes a guide block, a fixed shaft, a hydraulic cylinder, and a motion platform. Two sets of guide blocks are fixedly connected to the lower outer side of the machine body. A motion platform is slidably connected to the lower outer side of the guide blocks. A fixed shaft is fixedly connected to the outer side of the motion platform away from the machine body. Two connecting shafts are provided on the motion platform. A hydraulic cylinder is rotatably connected between the connecting shaft away from the machine body and the fixed shaft.

[0014] The external control system starts the hydraulic cylinder to extend outward, which in turn drives the motion platform to slide outward along the guide block. Then the motion platform drives the rock entry mechanism to slide outward synchronously, and the rock entry mechanism moves outward into place.

[0015] Furthermore, the connecting assembly includes a fixed housing, a second fixed shaft, a second hydraulic cylinder, a third fixed shaft, and a fixed base. The fixed base is fixedly connected to the lower side of the motion platform, the third fixed shaft is rotatably connected to the lower side of the fixed base, the fixed housing is fixedly connected to the lower side of the third fixed shaft, the second fixed shaft is fixedly connected to the side of the fixed housing away from the center of the machine body, and the second fixed shaft is rotatably connected to the second fixed shaft and the connecting shaft near the side of the machine body.

[0016] By activating hydraulic cylinder two to extend and retract, the fixed housing can be moved to rotate in an arc around the fixed seat, thereby achieving the purpose of breaking the rock layer from multiple angles and further improving the effect of rock entry and trenching.

[0017] Furthermore, the rock-entry mechanism two includes a hydraulic cylinder four, a main structure, a transmission component, and a drive component. The hydraulic cylinder four is fixedly connected to the inner side of the machine body through a horizontal plate. The output end of the hydraulic cylinder four is fixedly connected to the main structure. The transmission component and the drive component are provided on the main structure.

[0018] The control starts the hydraulic cylinder four, which drives the main structure, transmission components and drive components to move upward as a whole. Since the inner side of the machine body has a cavity for receiving the rock receiving mechanism two, the main structure, transmission components and drive components move into the receiving cavity.

[0019] Furthermore, the main structure includes a connecting frame, a connecting cylinder, a rotating shaft, and milling wheels. The output end of the hydraulic cylinder is fixedly connected to the connecting frame, and two sets of connecting cylinders are fixedly connected to the connecting frame. The inner side of the connecting cylinder is provided with a spiral groove corresponding to the spiral rod. Two sets of rotating shafts are provided on the lower side of the connecting frame, and milling wheels that are evenly distributed are fixedly connected to the outer side of the rotating shafts.

[0020] Furthermore, the transmission assembly includes a machine plate, a gearbox, a main gear, a driven gear, and a transmission gear. The machine plate and the gearbox are fixedly connected to the lower ends of the connecting frame, respectively. The main gear is provided inside the gearbox, the driven gear meshes with the outer side of the main gear, and the transmission gear meshes with the lower side of the driven gear. The transmission gear is fixedly connected to the rotating shaft.

[0021] Furthermore, the drive assembly includes a second piston motor, a drive shaft, a transmission box, a worm gear, and a turbine. The second piston motor is fixedly connected to one end of the connecting frame near the gear box. The output end of the second piston motor is fixedly connected to the worm gear. A turbine gear meshes with the lower side of the worm gear. The drive shaft is fixedly connected to the inner side of the turbine gear. A transmission box is provided on the outer side of the worm gear and the turbine gear. The worm gear and the drive shaft are rotatably connected to the inner wall of the transmission box. The transmission box is fixedly connected to the connecting frame.

[0022] Start the second piston motor. The second piston motor drives the worm to rotate. As the worm rotates, it meshes with and drives the turbine to rotate. The turbine drives the transmission shaft, which is fixedly connected to it, to rotate synchronously. The transmission shaft drives a driven gear to rotate. The driven gear meshes with and drives the transmission gear and the main gear. Then, through another driven gear meshing with another transmission gear, the purpose of driving the two sets of rotating shafts to rotate synchronously is achieved.

[0023] Furthermore, each of the main gear and one of the driven gears is fixedly connected to a mounting shaft, and bearings are connected to the end connections of the mounting shaft, transmission shaft, worm gear, and rotating shaft, which are used to maintain their rotation.

[0024] As the shaft rotates, it drives the milling wheel, which is fixedly connected to it, to rotate, thereby milling and grooving the underground. When encountering rock layers with complex geological conditions, the milling wheel can achieve a better grooving effect.

[0025] Furthermore, the fixed housing is trapezoidal, and a through hole corresponding to the screw rod is provided on the upper part of the fixed housing.

[0026] Furthermore, the inner side of the body has a cavity for receiving the second rock-collecting mechanism, and the motion platform has a groove corresponding to the guide block, so that the motion platform can slide linearly along the guide block.

[0027] Compared with the prior art, the present invention provides a special equipment for trenching into rock for diaphragm walls, which has the following beneficial effects:

[0028] 1. This invention, through the coordinated action of the guiding mechanism, rock entry mechanism one, and rock entry mechanism two, allows for free change of the device's shape during the construction of diaphragm wall trenching. It can be directly aligned with rock layers of different hardness and can freely switch between three different rock entry trenching methods: milling, crushing, and cutting. It has the effect of multi-purpose machine, changing the existing method of switching rock entry trenching methods by requiring the replacement of different equipment or disassembly and assembly of different components, and greatly improving the efficiency and quality of rock entry trenching.

[0029] 2. Through the coordinated action of the connecting components and the crushing components, the present invention can adjust the fixed shell to rotate in an arc around the fixed seat, thereby achieving the purpose of crushing and cutting the rock layer from multiple angles, and further improving the effect of rock grooving.

[0030] 3. This invention improves the quality and efficiency of rock trenching by automatically switching between three modes when facing rock layers of different hardness, reduces equipment costs, and extends equipment lifespan. In different modes, rock debris is discharged through an external slag removal system. At the same time, the modes can cooperate with each other to quickly break large pieces of rock debris into smaller pieces, which facilitates slag removal. Attached Figure Description

[0046] The crushing assembly 32 includes a hydraulic breaker 321, a crushing block 322, a hydraulic cylinder 323, a piston motor 324, and a screw rod 325. The hydraulic breaker 321 is fixedly connected to the inner side of the connecting assembly 31. The crushing block 322 is fixedly connected to the head of the hydraulic breaker 321.

[0047] Start hydraulic cylinder 23, retract hydraulic cylinder 23, thereby driving the motion platform 24 to reset, so that the rock entry mechanism 3 is reset, and then the bottom of the fixed housing 311 contacts the rock layer, and start hydraulic breaker 321. Since the hydraulic breaker 321 is provided with multiple evenly distributed sets in the fixed housing 311, the multiple sets of breaking blocks 322 impact the rock layer to break it.

[0048] Through the cooperation between rock entry mechanism 24 and rock entry mechanism 13, three different rock entry modes—milling, crushing, and cutting—can be switched.

[0049] When encountering rock layers of moderate hardness, the plunger motor 324 is activated, which drives the screw 325 to rotate, thereby using cutting force to cut and break the rock.

[0050] When facing rock layers of varying hardness, it can automatically switch between three modes of rock entry and grooving.

[0051] Furthermore, the guiding mechanism 2 includes a guide block 21, a fixed shaft 22, a hydraulic cylinder 23, and a motion platform 24. Two sets of guide blocks 21 are fixedly connected to the lower outer side of the machine body 1. The motion platform 24 is slidably connected to the lower outer side of the guide blocks 21.

The hydraulic cylinder 23 is rotatably connected between the connecting shaft away from the machine body 1 and the fixed shaft 22.

[0052] The external control system starts the hydraulic cylinder 23 to extend outward, which in turn drives the motion platform 24 to slide outward along the guide block 21. Then the motion platform 24 drives the rock entry mechanism 3 to slide outward synchronously, and the rock entry mechanism 3 moves outward into position.

[0053] Furthermore, the connecting assembly 31 includes a fixed housing 311, a second fixed shaft 312, a second hydraulic cylinder 313, a third fixed shaft 314, and a fixed base 315.

The second hydraulic cylinder 313 is rotatably connected between the second fixed shaft 312 and the connecting shaft near the side of the machine body 1.

[0054] By activating hydraulic cylinder 313 to extend and retract, the fixed housing 311 can be moved to rotate in an arc around the fixed seat 315, thereby achieving the purpose of breaking the rock layer from multiple angles and further improving the effect of rock entry and trenching.

[0055] Furthermore, the rock-entry mechanism 4 includes a hydraulic cylinder 41, a main structure 42, a transmission component 43, and a drive component 44. The hydraulic cylinder 41 is fixedly connected to the inner side of the machine body 1 via a horizontal plate. The output end of the hydraulic cylinder 41 is fixedly connected to the main structure 42. The transmission component 43 and the drive component 44 are provided on the main structure 42.

[0056] The hydraulic cylinder 41 is controlled to start, which drives the main structure 42, transmission assembly 43, and drive assembly 44 to move upward as a whole. Since the inner side of the machine body 1 has a cavity for receiving the rock receiving mechanism 4, the main structure 42, transmission assembly 43, and drive assembly 44 move into the receiving cavity.

[0057] Furthermore, the main structure 42 includes a connecting frame 421, a connecting cylinder 422, a rotating shaft 423, and milling wheels 424. The output end of the hydraulic cylinder 41 is fixedly connected to the connecting frame 421. Two sets of connecting cylinders 422 are fixedly connected to the connecting frame 421. The inner side of the connecting cylinder 422 is provided with a spiral groove corresponding to the spiral rod 325. Two sets of rotating shafts 423 are provided on the lower side of the connecting frame 421. Milling wheels 424 are evenly distributed and fixedly connected to the outer side of the rotating shafts 423.

[0058] Furthermore, the transmission assembly 43 includes a machine plate 431, a gearbox 432, a main gear 433, a driven gear 434, and a transmission gear 435. The machine plate 431 and the gearbox 432 are fixedly connected to the lower ends of the connecting frame 421, respectively. The main gear 433 is provided on the inner side of the gearbox 432. The driven gear 434 meshes with the outer side of the main gear 433. The transmission gear 435 meshes with the lower side of the driven gear 434. The transmission gear 435 is fixedly connected to the rotating shaft 423.

[0059] Furthermore, the drive assembly 44 includes a second piston motor 441, a drive shaft 442, a transmission box 443, a worm gear 444, and a turbine 445. The second piston motor 441 is fixedly connected to one end of the connecting frame 421 near the gearbox 432. The output end of the second piston motor 441 is fixedly connected to the worm gear 444. The turbine 445 is meshed on the lower side of the worm gear 444. The drive shaft 442 is fixedly connected to the inner side of the turbine 445. The transmission box 443 is provided on the outer side of the worm gear 444 and the turbine 445. The worm gear 444 and the drive shaft 442 are rotatably connected to the inner wall of the transmission box 443. The transmission box 443 is fixedly connected to the connecting frame 421.

[0060] When the plunger motor 441 is started, it drives the worm gear 444 to rotate. As the worm gear 444 rotates, it meshes with and drives the turbine 445 to rotate. The turbine 445 drives the transmission shaft 442, which is fixedly connected to it, to rotate synchronously. The transmission shaft 442 drives a driven gear 434 to rotate. The driven gear 434 meshes with and drives the transmission gear 435 and the main gear 433. Then, through another driven gear 434 meshing with another transmission gear 435, the purpose of driving the two sets of rotating shafts 423 to rotate synchronously is achieved.

[0061] Furthermore, a mounting shaft is fixedly connected to one end of both the main gear 433 and a set of driven gears 434. Bearings 5 ​​are connected to the end connections of the mounting shaft, transmission shaft 442, worm gear 444, and rotating shaft 423. The bearings 5 ​​are used to maintain their rotation.

[0062] While the rotating shaft 423 rotates, it drives the milling wheel 424, which is fixedly connected to it, to rotate, thereby milling and grooving the underground. When encountering rock layers with complex geological conditions, the milling wheel 424 can achieve a better grooving effect.

[0063] Furthermore, the fixed housing 311 is trapezoidal, and a through hole corresponding to the screw rod 325 is provided on the upper part of the fixed housing 311.

[0064] Furthermore, the inner side of the body 1 has a cavity for receiving the rock-collecting mechanism 2 4, and the motion platform 24 has a groove corresponding to the guide block 21, so that the motion platform 24 can slide linearly along the guide block 21.

[0065] The specific usage and function of this embodiment are as follows:

[0066] When using it, first fix the device to the external crawler crane. After determining the slotting location, start the external crawler crane to move the device to the area where it needs to be worked.

[0067] The device is then moved downwards, and the external hydraulic system is controlled to start the second piston motor 441. The second piston motor 441 drives the worm gear 444 to rotate. While rotating, the worm gear 444 meshes with and drives the turbine 445 to rotate. The turbine 445 drives the transmission shaft 442, which is fixedly connected to it, to rotate synchronously. The transmission shaft 442 drives a driven gear 434 to rotate. The driven gear 434 meshes with and drives the transmission gear 435 and the main gear 433. Then, through another driven gear 434 meshing with another transmission gear 435, the purpose of driving the two sets of rotating shafts 423 to rotate synchronously is achieved.

[0068] While the rotating shaft 423 rotates, it drives the milling wheel 424, which is fixedly connected to it, to rotate, thereby milling and grooving the underground. When encountering rock layers with complex geological conditions, the milling wheel 424 can achieve a better grooving effect.

[0069] When encountering a very hard rock layer, the external system switches to a new mode. The external control system activates hydraulic cylinder 23 to extend outward, which in turn drives the motion platform 24 to slide outward along the guide block 21. Then, the motion platform 24 drives the rock-entry mechanism 3 to slide outward synchronously. When the rock-entry mechanism 3 moves into position, the screw rod 325 and the piston motor 324 retract through hydraulic cylinder 323 and are returned to the inside of the fixed housing 311 without affecting the movement of the rock-entry mechanism 3.

[0070] Then, control the start hydraulic cylinder 41 to drive the main structure 42, transmission component 43, and drive component 44 to move upward as a whole. Since the inner side of the machine body 1 has a cavity for receiving the rock receiving mechanism 4, the main structure 42, transmission component 43, and drive component 44 move into the receiving cavity.

[0071] Then, the hydraulic cylinder 23 is activated again, and the hydraulic cylinder 23 is retracted, which in turn drives the motion platform 24 to reset, so that the rock entry mechanism 3 is reset. Then, the bottom of the fixed housing 311 contacts the rock layer, and the hydraulic breaker 321 is activated. Since the hydraulic breaker 321 has multiple evenly distributed sets in the fixed housing 311, the multiple sets of breaking blocks 322 impact the rock layer to break it.

[0072] At the same time, by activating hydraulic cylinder 313 to extend and retract, the fixed housing 311 can be moved to rotate in an arc around the fixed seat 315, thereby achieving the purpose of breaking the rock layer from multiple angles and further improving the effect of rock entry and trenching.

[0073] When encountering rock layers of moderate hardness, hydraulic cylinder 323 is activated. Hydraulic cylinder 323 drives the spiral rod 325 and piston motor 324 to extend outward. At the same time, piston motor 324 drives the spiral rod 325 to rotate, so that the rock is cut and broken by cutting force.

[0074] When the rock-entry mechanism 24 needs to work again, the hydraulic cylinder 23 is activated to extend, thereby driving the motion platform 24 to move outward again. Then, the hydraulic cylinder 41 is activated to drive the main structure 42, transmission component 43, and drive component 44 to move downward as a whole, so that the rock-entry mechanism 24 extends. Then, the motion platform 24 is controlled to reset again, and the rock-entry mechanism 3 abuts against the upper side of the rock-entry mechanism 24 to fix it.

[0075] When facing rock layers of different hardness, it can automatically switch between three modes of rock entry and trenching, which improves the quality and efficiency of rock entry and trenching, reduces equipment costs, and extends the service life of the equipment.

[0076] All of the above different modes use an external slag removal system to discharge rock debris during rock excavation. At the same time, the different modes can cooperate with each other to quickly break large pieces of rock debris into smaller pieces, which facilitates the slag removal work.

[0077] 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.
