Description

Technical Field

[0001] The invention belongs to the technical field of cleaning up cut waste in tunnel construction, and in particular relates to an openable and closable shovel plate device of a tunnel cantilever boring machine. Background Art

[0002] At present, during the tunneling process, the cantilever tunnel boring machine performs rotary cutting on the mountain, and a large amount of waste rock is generated by cutting. These waste rock and the like are easily accumulated in the front area of ​​the cantilever tunnel boring machine. As the cantilever tunnel boring machine gradually moves forward, the waste rock and the like located in front of it will be removed by its own shovel plate, but the waste rock and the like in the rest of the parts are extremely difficult to handle, so they are easily accumulated on both sides of the cantilever tunnel boring machine, causing waste accumulation. Due to the accumulation of waste, the lateral movement of the cantilever tunnel boring machine along the tunnel is affected, so that the cutting part of the cantilever tunnel boring machine cannot fully cut the mountain, and the accumulated waste needs to be removed and transferred manually, which increases the workload and work intensity, and affects the efficiency of construction. In order to reduce labor intensity, a shovel is often used to remove the accumulated waste; however, due to the small working space of the tunnel being excavated, it is necessary to withdraw the cantilever tunnel boring machine, and then drive the shovel into the excavation area to remove the accumulated waste, and then carry out excavation operations. Although this method reduces the intensity of work, it also greatly reduces the efficiency of excavation construction. Summary of the invention

The working principle and advantages of the present invention are: in the process of cutting and excavating the mountain by the boom tunneling machine, the crushed stones gradually fall off the mountain and form waste materials, which are cleared by two active cleaning mechanisms 500, so that the waste materials gradually enter the opening and closing shovel plate 700, and are continuously supplied to the conveyor belt, and the waste materials are transported away from the front area of ​​the boom tunneling machine. When the present invention cleans the waste materials on both sides of the front of the boom tunneling machine, the active opening and closing mechanism 200 is controlled to gradually open to a certain extent, and the opening and closing shovel plate 700 is also opened to a corresponding extent. According to the opening and closing conditions, the two active cleaning mechanisms 500 are controlled to change their cleaning forms, so that the two active cleaning mechanisms 500 continuously and efficiently clean the waste materials on both sides of the front of the boom tunneling machine, so that the cleaned waste materials are transported to the conveyor belt and transported by the conveyor belt, thereby avoiding the accumulation of waste materials on both sides of the boom tunneling machine. Moreover, the present invention can adjust the distance between the two active cleaning mechanisms 500, the opening of the opening and closing shovel plate 700, etc. by adjusting the opening of the active opening and closing mechanism 200, and cooperate with the adjustment of the cleaning form of the two active cleaning mechanisms 500 to achieve the purpose of adjusting the cleaning area in the area. In summary, the present invention can efficiently remove the waste generated by cutting, avoid the accumulation of waste on both sides of the boom tunneling machine and affect the tunneling operation, reduce the intensity of waste removal work, and improve the tunneling efficiency of the boom tunneling machine.

[0037] As a preferred embodiment of the present invention, Figure 3 , 4As shown, the assembly frame 100 includes a transverse beam 101, two vertical beams 104 and two sliding seats 105. Among them, two adapter seats 102 are constructed at the upper end of the transverse beam 101, and the two adapter seats 102 are both connected and fixed to the body of the cantilever tunnel boring machine. The two vertical beams 104 are symmetrically constructed on the lower end surface of the transverse beam 101, and the two sliding seats 105 are detachably connected to the lower ends of the two vertical beams 104, respectively, and each sliding seat 105 is slidably connected to the corresponding part of the opening and closing seat 300. In addition, a connecting seat 103 is constructed on the transverse beam 101, and the connecting seat 103 is connected to the corresponding part of the active opening and closing mechanism 200.

[0038] As a preferred embodiment of the present invention, Figure 4 , 5 As shown in Figures 7 and 8, the opening and closing seat 300 includes two symmetrically arranged sub-seat bodies, the active opening and closing mechanism 200 is arranged between the two sub-seat bodies, and the active opening and closing mechanism 200 is connected to the two sub-seat bodies. In this embodiment, each sub-seat body includes a horizontal arm 301, a vertical arm 302 and an adapter plate 305. Among them, the horizontal arm 301 is slidably connected with the corresponding sliding seat 105 on the assembly frame 100, the vertical arm 302 is constructed at the lower end of the horizontal arm 301, the adapter plate 305 is fixed at the lower end of the vertical arm 302, and each adapter plate 305 is connected to the corresponding vertical driving mechanism 600. In order to strengthen the connection strength between the horizontal arm 301 and the vertical arm 302, an oblique reinforcing rod 304 is fixedly connected between the two in this embodiment. The working principle and advantage of this embodiment are as follows: this embodiment controls the action of the active opening and closing mechanism 200 to drive the two sub-seat bodies to move closer to or farther away from each other (i.e., to make an opening and closing movement), thereby making the two sub-seat bodies drive the two active cleaning mechanisms 500 to move closer to or farther away from each other through the two transfer rods 400, and at the same time, the two sub-seat bodies drive the opening and closing shovel plates 700 to make corresponding opening and closing movements, thereby achieving the purpose of clearing waste at different positions.

[0039] As a preferred embodiment of the present invention, Figure 4-6As shown, the active opening and closing mechanism 200 includes a transverse driving member 205, a transverse elastic rod group and two vertical connecting members 202, and the two vertical connecting members 202 are symmetrically arranged between the two sub-seat bodies. Among them, the transverse elastic rod group includes a transverse sleeve 206 and two transverse rods 207, the transverse sleeve 206 is arranged at the middle position of the front end of the two vertical connecting members 202, and the two vertical connecting members 202 are respectively constructed with assembly ears 209, and the two transverse rods 207 are respectively fixed on the two assembly ears 209, and the ends of the two transverse rods 207 close to each other are respectively inserted into the two ends of the transverse sleeve 206, and a telescopic spring is installed in the transverse sleeve 206, and the two ends of the telescopic spring are respectively connected to the ends of the two transverse rods 207 close to each other. The transverse driving member 205 of this embodiment is arranged between the two vertical connecting members 202, and the two ends of the transverse driving member 205 are respectively connected to the two vertical connecting members 202, and the two vertical connecting members 202 are connected to the two vertical arms 302 one by one. The working principle and advantage of this embodiment are: when it is necessary to adjust the distance between the two active cleaning mechanisms 500 and adjust the opening and closing degree of the opening and closing shovel plate 700, the control method adopted is to control the movement of the horizontal driving member 205 so that it drives the two vertical connecting members 202 to approach or move away from each other. In this process, the two horizontal rods 207 move closer to or away from each other as the two vertical connecting members 202 approach or move away from each other, that is, the horizontal elastic rod group expands and contracts accordingly, and the movement distances of the two vertical connecting members 202 are the same, so that the two vertical connecting members 202 drive the two active cleaning mechanisms 500 to open and close through the two transfer rods 400. The transverse driving member 205 of the present embodiment is a transverse oil cylinder, at the end of the cylinder rod of the transverse oil cylinder is installed a movable rod movably connected, the movable rod extending out of the cylinder rod of the transverse oil cylinder is fixed on the corresponding vertical connecting member 202, a fixed spring is sleeved on the movable rod, the two ends of the fixed spring are respectively fixedly connected to the cylinder rod of the transverse oil cylinder and the corresponding vertical connecting member 202; in this way, when the active cleaning mechanism 500 is cleaning the waste, the active cleaning mechanism 500 encounters a hard object and transmits the external force it bears to the vertical connecting member 202 through the adapter rod 400, thereby adjusting the depth of the movable rod inserted into the cylinder rod of the transverse oil cylinder, thereby forcing the fixed spring to undergo elastic deformation, thereby avoiding the active cleaning mechanism 500 from having excessive hard contact with a large volume of waste stone in the waste, thereby causing damage to the active cleaning mechanism 500.

[0040] As a preferred embodiment of the present invention, Figure 5-7As shown, a vertical driving member 208 is connected between the horizontal sleeve 206 and the assembly frame 100. The vertical driving member 208 is a vertically arranged driving oil cylinder. The cylinder body of the driving oil cylinder is detachably connected to the connecting seat 103 on the assembly frame 100, and the cylinder rod of the driving oil cylinder is fixedly connected to the horizontal sleeve 206.

In this embodiment, connecting ears 203 are respectively constructed on the two vertical connecting members 202, and the two ends of the horizontal driving member 205 are respectively connected to the two connecting ears 203.

The working principle and advantages of this embodiment are: this embodiment can adjust the cleaning form of the active cleaning mechanism 500 for waste. Specifically, the vertical driving member 208 is controlled to move so that it drives the active opening and closing mechanism 200 to move in the vertical direction; during the movement of the active opening and closing mechanism 200, it drives the two transmission gears 210 to rotate in opposite directions through the two vertical racks 201, and drives the two transfer rods 400 to rotate, and finally makes the two active cleaning mechanisms 500 rotate a certain angle in opposite directions. Generally, the rotation angle range of each active cleaning mechanism 500 is 0-90°, thereby changing the cleaning form of each active cleaning mechanism 500 and changing the angle between the two active cleaning mechanisms 500, so as to achieve targeted cleaning of waste materials of different forms.

[0041] As a preferred embodiment of the present invention, Figure 1 , 7 As shown in , 8, the transfer rod 400 includes a rod-shaped body 401, one end of which is connected to the corresponding active cleaning mechanism 500, and the other end of the rod-shaped body 401 is configured with a tubular joint 404, which is assembled on the corresponding vertical arm 302 and connected with a pumping rubber hose, and the pumping rubber hose is connected to the suction end of the sludge pump. A second drainage channel 402 is configured in the rod-shaped body 401, and the second drainage channel 402 is connected to the pumping rubber hose through the tubular joint 404. Moreover, the rod-shaped body 401 is rotatably connected to the corresponding vertical connecting member 202, and the transmission gear 210 is assembled on the rod-shaped body 401. A conduction channel 403 is also configured in the rod-shaped body 401, and a hydraulic hose is installed at one end of the rod-shaped body 401 away from the active cleaning mechanism 500, one end of the hydraulic hose is connected to the conduction channel 403, and the other end of the hydraulic hose is connected to the hydraulic pump station.

[0042] As a preferred embodiment of the present invention, Figure 8-13As shown, the active cleaning mechanism 500 includes a driving member, a mounting shaft 501 and a plurality of scraping members, and the driving member generally adopts a power motor or a hydraulic motor 514. The power motor or the hydraulic motor 514 is fixedly mounted on the adapter rod 400, and the output shaft of the power motor or the hydraulic motor 514 is coaxially connected with the mounting shaft 501. The plurality of scraping members are installed on the mounting shaft 501 at intervals along the axial direction of the mounting shaft 501. The scraping member far from the adapter rod 400 is fixedly connected to the mounting shaft 501, and a buffer spring 508 is connected between two adjacent scraping members, and each buffer spring 508 is sleeved outside the mounting shaft 501. In this embodiment, a strip assembly groove 502 is constructed on the outer circumferential surface of the installation shaft 501, and the strip assembly groove 502 extends along the axial direction of the installation shaft 501. The scraper part of this embodiment includes a basic sleeve 516, and an assembly block 507 is constructed on the inner wall of the basic sleeve 516. The assembly block 507 is slidably assembled in the strip assembly groove 502, and a plurality of cleaning teeth 506 are evenly constructed on the outer wall of the basic sleeve 516 along its circumference. In this embodiment, an adapter sleeve 510 is configured on the adapter rod 400, and a connecting flange 515 is configured on the upper end of the adapter sleeve 510. The connecting flange 515 is connected and fixed to the power motor or hydraulic motor 514. The adapter sleeve 510 is connected and fixed to the adapter rod 400, and the adapter sleeve 510 is rotatably assembled outside the mounting shaft 501. The adapter sleeve 510 has a hydraulic chamber 511. A driving sleeve 509 is configured on the base sleeve 516 close to the adapter rod 400. The driving sleeve 509 extends into the hydraulic chamber 511, and the above-mentioned conducting channel 403 is connected with the hydraulic chamber 511. The working principle and advantages of this embodiment are: this embodiment controls the action of the power motor or hydraulic motor 514, so that it drives the installation shaft 501 to rotate and drives each scraper to rotate, thereby achieving the purpose of scraping waste and continuously conveying it to the conveyor belt through the opening and closing shovel plate 700. In the process of scraping, when the scraper encounters a large volume of waste stone or touches a hard object, the scraper moves axially along the mounting shaft 501 under the action of external force, which, on the one hand, enables the large volume of waste stone located between the two active cleaning mechanisms 500 to be engaged and transported to the conveyor belt, and on the other hand, avoids the situation where the cleaning teeth 506 of the scraper are damaged. During the cleaning process, the scraper is passively displaced axially under the action of external force, and at the same time, the buffer spring 508 undergoes elastic deformation and stores energy to facilitate the return of the scraper. In this embodiment, the spacing between the scrapers can be actively adjusted to facilitate the transportation of slightly larger volumes of waste stone. The means adopted are to inject or discharge hydraulic oil into the hydraulic chamber 511 through the conducting channel 403, so that the hydraulic oil or the buffer spring 508 drives the drive sleeve 509 to move axially along the mounting shaft 501. In this way, under the pressure or traction of the drive sleeve 509, the elastic deformation of the buffer spring 508 is coordinated to adjust the spacing between two adjacent scrapers.The two active cleaning mechanisms 500 of this embodiment can be driven by the active opening and closing mechanism 200 to move closer to or farther from each other, or rotate a certain angle, so that the distance between the two active cleaning mechanisms 500 gradually increases from bottom to top, thereby facilitating the synchronous cleaning of waste materials of different volumes. When the two active cleaning mechanisms 500 are both in a horizontal state, the mounting shaft 501 is in a horizontal state. At this time, the power motor or hydraulic motor 514 is controlled to operate so that it drives the mounting shaft 501 to drive each scraper to rotate synchronously. During the rotation of the scraper, the cleaning teeth 506 thereon rotate along the axis of the mounting shaft 501 and perform rotary excavation and transportation of the waste. When the two active cleaning mechanisms 500 are adjusted to a horizontal state, the opening and closing degree of the active opening and closing mechanism 200 is adjusted so that the distance between the two active cleaning mechanisms 500 is adjusted, thereby achieving the purpose of clearing waste materials at different positions.

[0043] As a preferred embodiment of the present invention, Figure 9-11 As shown, a shaft head 503 is configured at one end of the installation shaft 501 away from the adapter rod 400, and a blocking edge 504 is configured between the shaft head 503 and the installation shaft 501, and the blocking edge 504 extends radially outwardly along the installation shaft 501. In this embodiment, a first drainage channel 505 is opened in the installation shaft 501, and the first drainage channel 505 is connected to the shaft head 503. A drainage chamber 512 is configured in the adapter sleeve 510, and the drainage chamber 512 and the hydraulic chamber 511 are separated from each other, so that the drainage chamber 512 and the hydraulic chamber 511 are independent of each other, ensuring that different media pass through the drainage chamber 512 and the hydraulic chamber 511 respectively. The first drainage channel 505 and the second drainage channel 402 of this embodiment are connected through a transfer tube 513, and the two ends of the transfer tube 513 are fixedly connected to the transfer sleeve 510 and the transfer rod 400 respectively. A plurality of water holes are configured on the shaft head 503 and / or the installation shaft 501, and each water hole is connected to the first drainage channel 505. In this embodiment, the accumulated water in the tunnel can be sucked out by the silt extraction pump to prevent the excessive accumulation of water from affecting the efficiency of excavation. Specifically, under the suction of the silt extraction pump, the accumulated water enters the first drainage channel 505 through the water hole at the shaft head 503 and / or the installation shaft 501, and then passes through the drainage channel in the drainage cavity 512 in turn, and is finally discharged from the outlet of the silt extraction pump.

[0044] As a preferred embodiment of the present invention, Figure 1 , 14As shown, the vertical drive mechanism 600 includes a plug-in rod 602 of a vertical oil cylinder 601, a plug-in sleeve 603 and a connecting spring 604. The plug-in rod 602 is connected to the oil cylinder rod of the vertical oil cylinder 601, and one end of the plug-in rod 602 away from the vertical oil cylinder 601 is movably inserted in the plug-in sleeve 603, and the lower end of the plug-in sleeve 603 is fixedly connected to the corresponding position of the opening and closing type shovel board 700, and the connecting spring 604 is sleeved outside the plug-in rod 602, and the two ends of the connecting spring 604 are respectively connected to the plug-in rod 602 and the plug-in sleeve 603. The working principle and advantages of this embodiment are: when the spacing and / or angle of the two active cleaning mechanisms 500 are adjusted, in order to avoid the opening and closing shovel plate 700 interfering with the movement of the two active cleaning mechanisms 500, the two vertical oil cylinders 601 are controlled to act synchronously, so that the two drive the opening and closing shovel plate 700 to move downward, thereby avoiding the path track of the active cleaning mechanism 500. After the two active cleaning mechanisms 500 are adjusted, the vertical drive mechanism 600 is controlled to act so that the upper end of the opening and closing shovel plate 700 is close to the lower end of the active cleaning mechanism 500. In the process of waste removal in this embodiment, when the opening and closing shovel plate 700 contacts a hard object, the external force generated acts on the opening and closing shovel plate 700, and the opening and closing shovel plate 700 transmits this part of the external force to the connecting spring 604, so that the connecting spring 604 undergoes elastic deformation, and finally absorbs this part of the external force, thereby avoiding the situation where the opening and closing shovel plate 700 is damaged due to the concentrated force.

[0045] As a preferred embodiment of the present invention, Figure 1 , 15As shown in Figures 16 and 17, the retractable shovel plate 700 comprises a first shovel plate body 701 and a second shovel plate body 706 which are arranged opposite to each other. A fixing ear 703 is respectively configured on the side of the first shovel plate body 701 and the second shovel plate body 706 which are away from each other. The lower ends of the two plug-in sleeves 603 of the two vertical drive mechanisms 600 are respectively detachably connected to the two fixing ears 703. In this embodiment, a plurality of first shovel teeth 702 are configured at the front end of the first shovel plate body 701, and a plurality of second shovel teeth 709 are configured at the front end of the second shovel plate body 706; a first notch 705 is configured at the rear end of the first shovel plate body 701 and on the side close to the second shovel plate body 706, and a second notch 707 is configured at the rear end of the second shovel plate body 706 and on the side close to the first shovel plate body 701. A plug-in board 704 is configured in the middle of the first shovel board body 701 and close to one side of the second shovel board body 706, and a plug-in port 708 is configured in the middle of the second shovel board body 706 and close to one side of the first shovel board body 701, and the plug-in board 704 is movably inserted in the plug-in port 708. The feed end of the conveyor belt of this embodiment is arranged between the first notch 705 and the second notch 707, and the feed end of the conveyor belt is located below the rear end of the opening and closing shovel board 700, and the width of the conveyor belt is not less than the sum of the width of the first notch 705, the width of the second notch 707 and the width of the plug-in board 704, thereby ensuring that the waste cleaned by the two active cleaning mechanisms 500 can be fully conveyed out after entering between the first notch 705 and the second notch 707. This embodiment controls the active opening and closing mechanism 200 to perform opening and closing movements, so that it drives the two sub-seat bodies of the opening and closing seat 300 to perform corresponding opening and closing movements, and then the two sub-seat bodies drive the first shovel plate body 701 and the second shovel plate body 706 to perform opening and closing movements through two vertical driving mechanisms 600, thereby achieving the purpose of adjusting the shoveling range.
