Description

Technical Field

[0001] The present invention relates to the technical field of tunnel engineering, and in particular to a transfer device. Background Art

[0002] Excavation during excavation is an extremely important part of the construction of earth pressure balance shield tunnels, and the efficiency of excavation is an important factor affecting the construction progress of tunnel excavation. The traditional excavation method is to use a rail car to carry the slag box along the tunnel to the vertical shaft opening on the ground. The ground crane lifts the slag box vertically to the ground and transports the slag to the final storage place through the ground road transportation system. The full load weight of the slag box is large, generally more than 30 tons. With the development of cities, the limitation of ground space has made the excavation of urban underground tunnel construction more difficult. It is often encountered that there are immovable buildings or other facilities on the ground, which makes it impossible to construct a vertical shaft directly connected to the ground. Instead, it needs to be indirectly connected to the ground connecting shaft through a horizontal connecting channel, resulting in the inability to directly complete the vertical transportation of excavation and auxiliary materials in the construction. During construction, the slag and auxiliary materials need to be transported to the vertical shaft leading to the ground through the horizontal connecting channel to achieve vertical transportation. However, the horizontal connecting channel is usually limited in height and width due to structural limitations, and cannot meet the installation size and working range requirements of conventional large-tonnage lifting equipment and the minimum turning radius requirements of the excavation train. At present, the commonly used methods of transporting slag include turntable transfer device combined with rail car transfer and transportation, long-distance belt conveyor device, etc. The turntable transfer method can meet the requirements of height and width space without changing the previous transportation method, but each transfer must first disconnect the connection devices of each section of the rail car and the gas and electrical circuits, and then reconnect them, which has low transfer efficiency. The use of long-distance belt conveyor devices requires changing the previous transportation method and requires laying belt conveyors throughout the entire process, which has the disadvantages of high cost, occupying tunnel working space, and being easily restricted by construction conditions.

[0003] Therefore, there is an urgent need for a transfer equipment that can be used in a connecting channel at a lower height and has low cost and high efficiency. Summary of the invention

[0050] In order to enable those skilled in the art to better understand the technical solution of this embodiment, the technical solution of this embodiment is further described below with reference to the accompanying drawings and through specific implementation methods.

[0051] With the development of cities, the limitation of ground space has made the excavation of urban underground tunnel construction more difficult. It is often encountered that there are immovable buildings or other facilities on the ground, which makes it impossible to construct a vertical shaft directly connected to the ground. Instead, it is necessary to connect the vertical shaft connected to the ground indirectly through a horizontal connecting channel. However, the construction layout of the tunnel will result in the inability to directly complete the vertical transportation of excavated soil and auxiliary materials to the ground in the tunnel during construction. During construction, the slag and auxiliary materials need to be transported to the vertical shaft leading to the ground through the horizontal connecting channel to achieve vertical transportation. Specifically, if Figure 1 and Figure 2 The schematic diagram of the tunnel construction layout is shown in Figure 1 As shown, the open-cut shaft 300 is set at the open-cut tunnel 400, and the dark-cut tunnel 200 is connected to the open-cut shaft 300 through a connecting passage, and then the open-cut shaft 300 can be connected to the ground 500, so as to realize the excavation and material transportation in the dark-cut tunnel 200. Figure 2 As shown, the underground tunnel only includes a dark-cut tunnel 200, which is connected to an open-cut shaft 300 through a connecting passage, and excavation and material transportation in the dark-cut tunnel 200 can also be achieved.

[0052] The transfer equipment 100 in this embodiment is described with the first currently common tunnel construction layout, such as Figure 3 As shown, the transfer equipment 100 is arranged at the connecting passage, and is used to transfer the materials of the dark excavated tunnel 200 to the open excavated shaft 300. The transfer equipment 100 provided in this embodiment includes a support assembly 1, a driving assembly 2, a hydraulic drive assembly 3 and a hook assembly 4. The support assembly 1 is arranged along the length direction of the connecting passage, the driving assembly 2 is arranged on the support assembly 1 and can move relative to the support assembly 1 along the length direction of the connecting passage, and the hook assembly 4 for hanging the material is connected to the driving assembly 2 through the hydraulic drive assembly 3. Since the hydraulic drive assembly 3 has a compact structure and a large lifting force, the transfer equipment 100 provided by the present invention can be used in a connecting passage with a lower height. In addition, when the transfer equipment 100 provided by the present invention fails, only the corresponding parts need to be repaired, which can save the cost of changing the civil engineering structure. Compared with the transportation method using a long-distance belt conveyor, the cost of purchasing a complete set of equipment can be saved. Compared with the turntable transfer method, it helps to improve the efficiency of the slag box and material transfer. It can be reused, does not generate reinforcement and demolition waste, and meets the requirements of energy saving and environmental protection.

[0053] The support assembly 1 is arranged in the connecting channel, so that the civil engineering structure and the previous transportation method are not changed, and the maintenance cost is low; the hydraulic drive assembly 3 has a compact structure and a large lifting force, and can lift large-tonnage materials in a low space, and is used to drive the hook assembly 4 to move in the vertical direction. The transfer equipment 100 provided in this embodiment can lift and transfer large-tonnage materials in a low space without changing the civil engineering structure and the previous transportation method, and has the advantages of low maintenance cost, simple installation, and not occupying the tunnel operation space. The transfer equipment 100 provided in this embodiment can be used to transport slag boxes, and can also be used to transport other materials.

[0054] In this embodiment, the support assembly 1 includes columns, beams, rails, end pieces, connectors and embedded parts. The height of the lower edge of the beam should allow the muck transport train to pass through, and a safe distance should be reserved; the columns and beams can be made of steel plate welded structure or profiles plus welded ribs to strengthen the structure, which is convenient for installation and transportation; the length of the beam should not be too long; the rail model is selected according to the lifting tonnage; the columns and embedded parts, the columns and beams, and the beams can be connected by bolts, which is convenient for installation and disassembly. It should be noted that the "front" in this embodiment refers to the side of the crane assembly 2 close to the dark tunnel 200, the "rear" refers to the side of the crane assembly 2 close to the open shaft 300, and the "left" and "right" refer to the positions determined by referring to the "front" and "rear" directions.

[0055] For example, Figure 3 Combination Figure 4 As shown, the transfer equipment 100 further includes a driving safety component 6, which includes a driving switch 61 and a driving limit plate 62. In this embodiment, the driving switch 61 includes a front limit switch and a rear limit switch, which are respectively arranged at the front end and the rear end of the right side of the driving component 2, and the driving limit plate 62 includes a front limit plate and a rear limit plate, which are respectively arranged at the front and rear positions on the track of the support component 1 corresponding to the driving switch 61. During the movement of the driving component 2, when the driving switch 61 touches the driving limit plate 62, the driving component 2 can stop automatically, which can effectively protect the driving component 2 and prevent the driving component 2 from rushing out of the track of the support component 1 due to failure to stop in time and causing damage.

[0056] In other embodiments, the driving switch 61 can be set on any track of the two tracks of the support assembly 1, and the driving limit plate 62 can be set at a position of the driving assembly 2 corresponding to the driving switch 61, which can also achieve the above-mentioned effect.

[0057] For example, Figure 5As shown, the transfer equipment 100 provided in this embodiment also includes a lifting safety component 7, and the lifting safety component 7 includes a lifting switch 71 and a lifting limit plate 72. In this embodiment, the lifting switch 71 is set on the hook component 4, and the lifting limit plate 72 includes an upper limit plate and a lower limit plate, which are set at a position corresponding to the lifting switch 71 on the driving component 2. When the hook component 4 is connected to the material box, the hydraulic drive component 3 is started to drive the hook component 4 to move upward. When the lifting switch 71 touches the upper limit plate, the hydraulic drive component 3 stops driving the hook component 4, which can effectively protect the hook component 4; similarly, when the hook component 4 needs to put down the material box, the hydraulic drive component 3 drives the hook component 4 to move downward. When the lifting switch 71 touches the lower limit plate, the hydraulic drive component 3 stops driving to prevent the hook component 4 from colliding with the driving component 2 when it descends, which can effectively protect the hook component 4 and the driving component 2.

[0058] In other embodiments, the lifting switch 71 can be set on the driving component 2, and the lifting limit plate 72 can be set on the hanging component 4 at a position corresponding to the lifting switch 71, which can also achieve the above-mentioned effect.

[0059] Specifically, if Figure 6 As shown, the traveling assembly 2 includes a traveling frame 21 and a traveling driving mechanism 24 . The traveling frame 21 is provided with traveling wheels 23 . The traveling driving mechanism 24 is used to drive the traveling wheels 23 to rotate, thereby realizing the movement of the traveling assembly 2 along the supporting assembly 1 .

[0060] Preferably, a transmission shaft 22 is rotatably provided on the traveling frame 21, and a traveling wheel 23 is provided on the outer periphery of the transmission shaft 22; the traveling driving mechanism 24 is connected to the transmission shaft 22 through a gear mechanism 25, and the traveling driving mechanism 24 drives the transmission shaft 22 to rotate. In this embodiment, the traveling driving mechanism 24 includes a motor, and the gear mechanism 25 includes an upper gear set and a lower gear set. The output shaft of the motor is connected to the upper gear set and drives the upper gear set to rotate, and the upper gear set drives the lower gear set to rotate. The lower gear set is connected to the transmission shaft 22, and the two sides of the transmission shaft 22 are provided with traveling wheels 23. The traveling wheels 23 can reduce the friction force of the traveling assembly 2 moving relative to the supporting assembly 1. The motor is connected to the transmission shaft 22 through the gear mechanism 25, which can ensure stable rotation transmission on the one hand, and on the other hand, the moving speed of the traveling assembly 2 can be effectively adjusted through the gear mechanism 25.

[0061] In other embodiments, the driving mechanism in the travel driving mechanism 24 can also be a hydraulic motor that directly drives the travel wheel 23 to rotate. Specifically, the hydraulic motor is connected to the hydraulic reducer and connected to the travel wheel through a flange bearing, so that the hydraulic motor drives the travel wheel to rotate.

[0062] Exemplarily, the hook assembly 4 includes a detachably connected lifting beam 41 and a hanger 42. In this embodiment, the lifting beam 41 is a plate-welded or profile-and-plate-welded structure, and the hanger 42 is different according to the different structures of the hoisted objects, and adopts a detachable connection method to facilitate the transportation of slag boxes or materials of different specifications.

[0063] Specifically, the hanger 42 includes a box hanger 421 and a material hook 422. The box hanger 421 is symmetrically arranged on both sides of the lifting beam 41 for hanging the material box; the material hook 422 is arranged in the middle of the lifting beam 41 for hanging the material bag. The large-tonnage box hangers 421 are arranged on both sides of the lifting beam 41 to facilitate lifting the material box and ensure that the lifting beam 41 is evenly stressed. The small-tonnage material hook is arranged in the middle of the lifting beam 41 to facilitate lifting the pipe segment, rail and other auxiliary materials. In other embodiments, the hanger 42 may also include only the box hanger 421 or the material hook 422.

[0064] Optionally, the transfer device 100 further includes a guide assembly 5, which enables the hook assembly 4 to move along a specified direction relative to the traveling assembly 2. Figure 7 As shown, the guide assembly 5 in this embodiment includes a guide sleeve 51 and a guide column 52, wherein the guide sleeve 51 is arranged on the traveling assembly 2, and the guide column 52 is arranged on the hanging assembly 4. The guide column 52 can slide up and down in the guide sleeve 51 on the traveling assembly 2, and a sliding sleeve is arranged between the guide column 52 and the guide sleeve 51, and the sliding sleeve is nested in the guide sleeve 51, which plays a wear-resistant lubricating role, and can ensure the vertical lifting of the lifting beam 41, and avoid the hydraulic drive assembly 3 being damaged by the lateral force during the walking process of the traveling assembly 2, and the lifting beam 41 being destabilized as a whole. Specifically, the lower part of the guide column 52 adopts an anti-slip design to prevent the guide column 52 from slipping out of the guide sleeve 51 during the lifting process of the hanging assembly 4. In other embodiments, the guide sleeve 51 is arranged on the hanging assembly 4, and the guide column 52 is arranged on the traveling assembly 2, which can also achieve the above-mentioned effect.

[0065] For example, Figure 8 Combination Figure 3As shown, the hydraulic drive assembly 3 includes a hydraulic pump 31 and a lifting drive mechanism 32, wherein the hydraulic pump 31 is arranged on the traveling frame 21; the lifting drive mechanism 32 includes a piston rod 321 and a cylinder barrel 322, the free end of the piston rod 321 is connected to the lifting beam 41 through the cylinder seat 323, and the cylinder barrel 322 is connected to the traveling frame 21 through the positioning plate 33. The cylinder seat 323 is fixed on the lifting beam 41. In order to adapt to the shaking of the traveling assembly 2 when the hanging assembly 4 is traveling, the piston rod 321 and the cylinder seat 323 are set to a swingable connection mode. The head of the piston rod 321 is a spherical joint with a through hole. The piston rod 321 is connected to the cylinder seat 323 through a positioning pin, and the piston rod 321 can swing slightly with the positioning pin as the center. The driving mechanism of the lifting drive mechanism 32 is a hydraulic cylinder, which has a compact structure, a large lifting force, and can ensure smooth operation.

[0066] Specifically, Fig. 9 Combination Fig.10 As shown, the outer periphery of the oil cylinder barrel 322 in this embodiment is provided with an ear shaft 324, which is limited by the positioning plate 33. The purpose of using the ear shaft 324 is to allow the oil cylinder barrel 322 to swing at a certain angle to compensate for the error caused by installation or deformation, ensure that the force on the oil cylinder barrel 322 is more uniform, and thus better protect the oil cylinder barrel 322. Among them, the positioning plate 33 includes a first positioning plate 331 and a second positioning plate 332, wherein the first positioning plate 331 is connected to the traveling frame 21, and a first opening groove 3311 is opened on the first positioning plate 331; the ear shaft 324 of the oil cylinder barrel 322 passes through the second positioning plate 332 and can be accommodated in the first opening groove 3311, and the first positioning plate 331 and the second positioning plate 332 are fixedly connected. Specifically, the first positioning plate 331 is fixedly connected to the traveling frame 21 by welding. The two first positioning plates 331 are symmetrically arranged with the oil cylinder barrel 322 as the center to limit the movement of the oil cylinder barrel 322 in the direction perpendicular to the first positioning plates 331, and to ensure that the forces on both sides of the traveling component 2 are uniform. The first opening groove 3311 is provided on the first positioning plate 331, so that the oil cylinder barrel 322 with the ear shaft 324 can be inserted between the two first positioning plates 331, so as to facilitate the installation of the oil cylinder barrel 322. The second positioning plate 332 is connected to the ear shaft 324 on the oil cylinder barrel 322. When the oil cylinder barrel 322 is placed between the two first positioning plates 331, the first positioning plate 331 and the second positioning plate 332 are fixed together by the fixing member 333. The fixing member 333 can be a bolt, a pin, etc.

[0067] For example, Fig.11As shown, in this embodiment, a through hole 3321 is provided on the second positioning plate 332, and the ear shaft 324 on the oil cylinder barrel 322 is inserted into the through hole 3321 on the second positioning plate 332, and then the second positioning plate 332 is fixedly connected to the first positioning plate 331 through the fixing member 333. In other embodiments, a second opening groove is provided on the second positioning plate 332, and the second opening groove cooperates with the first opening groove 3311 to limit the movement of the ear shaft 324 relative to the first positioning plate 331 and the second positioning plate 332, which can also achieve the above-mentioned effect.

[0068] It should be noted that the transfer equipment 100 provided in this embodiment also includes a buzzer. When the traveling component 2 is moving, the buzzer makes a sound to remind the staff.

[0069] Fig.12 Combination Figure 4 As shown, the transfer equipment 100 provided in this embodiment further includes a control system 8, which includes a drive control module 81 and a safety control module 82. The drive control module 81 includes a driving unit 811 and a lifting unit 812. The driving unit 811 is electrically connected to the driving mechanism 24 for controlling the driving mechanism 24; the lifting unit 812 is electrically connected to the lifting mechanism 32 for controlling the hydraulic pump 31. The safety control module 82 includes a driving safety unit 821 and a lifting safety unit 822. The driving safety unit 821 is electrically connected to the driving safety mechanism for receiving a signal from the driving switch 61; the lifting safety unit 822 is electrically connected to the lifting safety mechanism for receiving a signal from the lifting switch 71.

[0070] Specifically, the control system 8 in this embodiment also includes a remote control panel to facilitate the staff to remotely operate the transfer equipment 100.

[0071] The working principle of the transfer device 100 provided in this embodiment is as follows, and is described by taking the transfer of materials and a slag box in a dark tunnel 200 to the ground as an example:

[0072] First, the support assembly 1 is installed in the connecting passage, and the track of the support assembly 1 is perpendicular to the transport train track in the open-cut shaft 300 and the dark-cut tunnel 200;

[0073] Secondly, when the transport train in the dark tunnel 200 reaches the bottom of the track of the support assembly 1, it stops, starts the lifting drive mechanism 32 to drive the material hook 422 or the box hanger 421 to descend to the material or slag box, and closes the lifting drive mechanism 32. After the staff connects the material hook 422 with the material or connects the box hanger 421 with the slag box, restarts the lifting drive mechanism 32, and lifts the material or slag box to leave the transport train, and closes the lifting drive mechanism 32;

[0074] Again, start the crane drive mechanism 24. When the crane component 2 moves along the track on the support component 1 with the material or the slag box to the crane limit plate 62 at the open-cut shaft 300, the crane component 2 stops automatically. The staff can start the lifting drive mechanism 32 through the remote control control panel of the control system 8 to lower the material box to the slag truck or the stand in the open-cut shaft 300, close the lifting drive mechanism 32, separate the material hook 422 from the material or separate the box hanger 421 from the slag box, and start the lifting drive mechanism 32 to return the material hook 422 or the box hanger 421 to its original position.

[0075] Finally, the materials or slag box transferred to the open-cut shaft 300 are hoisted to the ground by the lifting equipment on the ground, and the materials and slag box are transported out.
