Description

Technical Field

[0001] This invention belongs to the technical field of underground construction equipment, specifically relating to a cutting and transferring device for underground construction. Background Technology

[0002] Underground construction typically refers to engineering construction activities carried out below the earth's surface, including the development of different types of underground space such as basements, underground passages, and underground parking lots. These projects aim to make full use of underground space resources, improve land use efficiency, and meet the needs of urban development.

[0003] When protecting an excavation pit, support beams need to be inserted to stabilize it. After the pit is stabilized, the support beams need to be removed. The following problems exist in the process of removing the support beams:

[0004] In underground foundation pits with two or more levels, the support beams are also divided into multiple beams, distributed vertically. During the transfer of support beams, the lower support beams are usually removed first, followed by the upper support beams. The lower and upper support beams are at different heights. Therefore, this application proposes a cutting and transferring device for underground construction, whose internal top plate has upper and lower transfer states, suitable for cutting and transferring the bottom and upper support beams in the foundation pit, respectively. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting and transferring device for underground construction, 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 cutting and transferring device for underground construction, comprising a cutting and transferring frame, which is entered into or pulled out of the foundation pit by a hoisting device. An upper support beam and a lower support beam are provided in the foundation pit. A top plate is provided on the cutting and transferring frame, and the top plate is connected to a height adjustment mechanism. The height adjustment mechanism is used to drive the top plate to move up and down, so that the top plate has at least two states, including an upper transfer state and a lower transfer state.

[0007] When the top plate is in the downward transfer state, the first bottom plate and the top plate in the cutting transfer frame are located on the upper and lower sides of the lower support beam, respectively. When the top plate is in the upward transfer state, the second bottom plate and the top plate in the cutting transfer frame are located on the upper and lower sides of the upper support beam, respectively.

[0008] A cutting device is installed on the underside of the top plate, and the cutting device is connected to a cutting lifting device;

[0009] Several transfer rings are installed on the upper side of the cutting transfer frame.

[0010] Preferably, the second base plate is connected to a telescopic unit, which is installed on the side of the cutting transfer frame away from the upper support beam, and a tripod is installed at the lower end of the telescopic unit.

[0011] Preferably, a pressure plate is installed on the lower side of the top plate. The pressure plate is L-shaped and connected to a pressure plate lifting unit. The pressure plate lifting unit is connected to the top plate via a bracket.

[0012] Preferably, the bottom of the cutting transfer frame is provided with a movable component, which includes two casters that are evenly distributed, and the rotating shafts installed on the upper ends of the casters are inserted into the support base.

[0013] Preferably, the support base is mounted on the lifting plate, and a transmission wheel is sleeved on the outside of the rotating shaft. The two transmission wheels on the two casters are connected by a transmission belt. One of the casters is connected to a drive motor, which drives the caster connected to it to rotate.

[0014] Preferably, the lifting plate is located in the lifting groove of the cutting transfer frame, and the lifting plate is connected to a buffer.

[0015] Preferably, a protective component is provided above the cutting and transfer frame. The protective component includes an adjustment plate, which is mounted on a support, which is located on the upper side of the top plate.

[0016] Preferably, two parallel protective plates are installed on the upper side of the adjustment plate, and an inclined plate is provided on the lower side of the adjustment plate, the inclined plate being connected to the output end of the protective power telescopic rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The top plate of this invention can move up and down under the drive of the height adjustment mechanism. When the top plate is in the downward transfer state, it is located above the lower support beam, while the first bottom plate is located below the lower support beam. The cutting device on the top plate can cut the lower support beam located between the two, cutting off the lower support beam in the corresponding area. The cut-off lower support beam falls onto the upper side of the first bottom plate. When the top plate is switched to the upward transfer state, it is located above the upper support beam. The position of the second bottom plate is adjusted by the telescopic unit, allowing the second bottom plate to move to the lower side of the upper support beam. At this time, the upper support beam is located between the top plate and the second bottom plate. After the cutting device on the top plate is activated, it cuts the upper support beam, and the cut-off upper support beam falls onto the upper side of the second bottom plate. These two states are respectively applicable to the cutting and dismantling work of the upper and lower support beams.

[0019] Second, before the cutting and transporting frame is pulled out of the pit by the hoisting equipment, the protective power telescopic rod is activated. It can drive the adjusting plate to rotate upward around the support through the inclined plate, so that the adjusting plate tilts upward. In this way, during the process of the cutting and transporting frame rising, if the upper support beam and the cutting and transporting frame overlap vertically, the adjusting plate on the upper side will contact the upper support beam first and press against the upper support beam, avoiding direct collision between the components on the cutting and transporting frame and the upper support beam, protecting the internal components of the cutting and transporting frame, and preventing the upper support beam from loosening prematurely due to the collision of the cutting and transporting frame.

[0020] Third, the cutting and transfer frame of this invention is equipped with a moving component. The internal drive motor can drive the rotating shaft and casters to rotate. The two casters rotate synchronously through a transmission wheel and a transmission belt, which can adjust the orientation of the casters. The casters have a power function, and the direction of movement changes accordingly when the orientation of the casters changes. The moving component composed of this component can move the cutting and transfer frame to multiple areas in the foundation pit. At the same time, in the process of cutting the lower support beam, the moving component can move the lower support beam to an area at a certain distance from the upper support beam. In this way, the top plate can avoid the upper support beam and avoid collision during the upward movement. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1-9 A cutting and transfer device for underground construction includes a foundation pit 1, an upper support beam 2, a lower support beam 3, and a cutting and transfer frame 4. A top plate 5 is provided on the cutting and transfer frame 4. The top plate 5 is connected to a height adjustment mechanism 6. The height adjustment mechanism 6 is used to drive the top plate 5 to move up and down, so that the top plate 5 has at least two states, including an upper transfer state and a lower transfer state.

[0033] Specifically, when the top plate 5 is in the downward transfer state, the first bottom plate 7 and the top plate 5 in the cutting transfer frame 4 are located on the upper and lower sides of the lower support beam 3, respectively. When the top plate 5 is in the upward transfer state, the second bottom plate 8 and the top plate 5 in the cutting transfer frame 4 are located on the upper and lower sides of the upper support beam 2, respectively.

[0034] The top plate 5 can move up and down under the drive of the height adjustment mechanism 6. The top plate 5 is located on the upper side of the lower support beam 3, while the first bottom plate 7 is located on the lower side of the lower support beam 3. Thus, the lower support beam 3 is located between the top plate 5 and the first bottom plate 7. The cutting device 10 on the top plate 5 can cut the lower support beam 3 located between the two, cutting off the lower support beam 3 in the corresponding area. The cut lower support beam 3 falls on the upper side of the first bottom plate 7. The cutting transfer frame 4 is pulled upward by the hoisting rope, which can transfer the cut lower support beam 3 from the pit 1. Repeat the above operation to transfer the entire lower support beam 3. Then, the cutting and transfer work of the upper support beam 2 is carried out.

[0035] The height of the top plate 5 is adjusted by the height adjustment mechanism 6, so that it is converted to the upward transfer state. At this time, the top plate 5 is located above the upper support beam 2. The position of the second bottom plate 8 is adjusted by the telescopic unit 9, so that the second bottom plate 8 moves to the lower side of the upper support beam 2. At this time, the upper support beam 2 is located between the top plate 5 and the second bottom plate 8. After the cutting device 10 on the top plate 5 is started, it cuts the upper support beam 2. The cut upper support beam 2 falls to the upper side of the second bottom plate 8. The cutting transfer frame 4 is pulled upward by the hoisting rope, so that the cut upper support beam 2 can be taken out from the pit 1, thereby completing the cutting and dismantling work of the upper support beam 2.

[0036] In a further embodiment, the second base plate 8 is connected to the telescopic unit 9. The telescopic unit 9 can move the second base plate 8 to the lower side of the upper support beam 2 and also pull it away from under the upper support beam 2. At this time, the second base plate 8 does not obstruct the vertical movement of the top plate 5. (Refer to...) Figure 5 The telescopic unit 9 is installed on the side of the cutting and transfer frame 4 away from the upper support beam 2, and a tripod is installed at the lower end of the telescopic unit 9.

[0037] In order to cut and transfer the upper support beam 2 and the lower support beam 3 from the pit 1, the cutting device 10 is set on the lower side of the top plate 5, and the cutting device 10 is connected to the cutting lifting device 11. The cutting device 10 and the cutting lifting device 11 work together to cut the corresponding upper support beam 2 and lower support beam 3, so that the upper support beam 2 and lower support beam 3 can be transferred in sections.

[0038] To prevent the upper support beam 2 or the lower support beam 3 from swaying during the cutting process of the cutting device 10, a pressure plate 12 is installed on the lower side of the top plate 5. The pressure plate 12 is L-shaped and connected to the pressure plate lifting unit 13. The pressure plate lifting unit 13 is connected to the top plate 5 through a bracket. The pressure plate lifting unit 13 can drive the pressure plate 12 to move up and down. Before the cutting device 10 cuts the upper support beam 2 and the lower support beam 3, the pressure plate lifting unit 13 is activated to move the pressure plate 12 downward and fix the upper support beam 2 or the lower support beam 3, so that either of them remains stable during the cutting process, ensuring the stability and safety of the cutting process.

[0039] The cutting and transfer frame 4 can move inside the pit 1. After the hoisting equipment connected by the hoisting rope sends the cutting and transfer frame 4 into the pit 1, the moving component 14 connected to the cutting and transfer frame 4 can move it to a suitable position. It is not necessary to use the hoisting equipment to send it to the cutting position. There are upper support beams 2 and lower support beams 3 near the cutting position. If the cutting and transfer frame 4 is hoisted directly to the position, it is necessary to avoid collisions between the cutting and transfer frame 4 and the upper support beams 2 and lower support beams 3. However, by moving the cutting and transfer frame 4 to the cutting position through the moving component 14, the difficulty of hoisting by the hoisting equipment operator can be reduced. The moving component 14 is provided at the bottom of the cutting and transfer frame 4.

[0040] Specifically, the movable component 14 includes two casters 1401, which are arranged side by side. The rotating shaft mounted on the upper end of the caster 1401 is inserted into the support base 1402. The support base 1402 is mounted on the lifting plate 1405. The caster 1401 and the support base 1402 are rotatably connected by the rotating shaft and bearings. A transmission wheel 1404 is sleeved on the outside of the rotating shaft. The two transmission wheels 1404 on the two casters 1401 are connected by a transmission belt 1403. The transmission belt 1403 is toothed, so that the two casters 1401 can rotate synchronously. One of the casters 1401 is connected to a drive motor, which drives the caster 1401 connected to it to rotate.

[0041] The drive motor can drive the rotating shaft and casters 1401 to rotate. The two casters 1401 rotate synchronously through the transmission wheel 1404 and the transmission belt 1403, which can adjust the orientation of the casters 1401. The casters 1401 have a power function. The direction of movement changes accordingly when the orientation of the casters 1401 changes. The moving assembly 14 composed of these components can move the cutting transfer frame 4 to multiple areas in the pit 1. At the same time, in the process of cutting the lower support beam 3, the moving assembly 14 can move the lower support beam 3 to an area at a certain distance from the upper support beam 2. In this way, the top plate 5 can avoid the upper support beam 2 during the upward movement, thus avoiding collision.

[0042] More specifically, the lifting plate 1405 is located in the lifting groove of the cutting transfer frame 4, and the lifting plate 1405 is connected to the buffer 1406. The buffer 1406 cooperates with the caster 1401 to enable the cutting transfer frame 4 to move stably forward and backward when moving under no load or when moving the upper support beam 2 and lower support beam 3 after cutting.

[0043] To facilitate the connection between the cutting transfer frame 4 and the lifting rope and hoisting equipment, several transfer lifting rings 15 are provided on the upper side of the cutting transfer frame 4.

[0044] During the dismantling of the upper support beam 2 and lower support beam 3 in the foundation pit 1, in order to avoid the collapse of the foundation pit 1, the lower support beam 3 located on the lower side is usually dismantled first. After the lower support beam 3 is cut, it is easy to collide with the upper support beam 2 located on its upper side during its upward movement. In order to avoid the collision, a protective component 16 is set above the cutting and transfer frame 4. The protective component 16 includes an adjusting plate 1601, which is set on the support 1603. The support 1603 is set on the upper side of the top plate 5. Two parallel protective plates 1602 are installed on the upper side of the adjusting plate 1601. An inclined plate 1604 is set on the lower side of the adjusting plate 1601. The inclined plate 1604 is connected to the output end of the protective power telescopic rod 1605.

[0045] The protective power telescopic rod 1605 uses a hydraulic cylinder. After cutting a section of the lower support beam 3, it needs to be transferred away by a hoisting rope and hoisting equipment. Before the transfer, the protective power telescopic rod 1605 needs to be activated. It can drive the adjusting plate 1601 to rotate upward around the support 1603 through the inclined plate 1604, so that the adjusting plate 1601 tilts upward. In this way, during the process of the cutting transfer frame 4 rising, if there is a partial overlap between the upper support beam 2 and the cutting transfer frame 4, the adjusting plate 1601 located on the upper side will contact the upper support beam 2 first and press against the upper support beam 2 to avoid direct collision between other parts on the cutting transfer frame 4 and the upper support beam 2.

[0046] Working principle:

[0047] The cutting and transfer frame 4 is sent into the pit 1 by hoisting equipment. The moving component 14 inside the cutting and transfer frame 4 contacts the ground of the pit 1. The moving component 14 can drive the cutting and transfer frame 4 to move inside the pit 1 and move it to the position of the lower support beam 3 and the upper support beam 2.

[0048] The cutting transfer frame 4 is first moved to the position of the lower support beam 3. At this time, the top plate 5 is located on the upper side of the lower support beam 3. The cutting device 10 and the cutting lifting device 11 on the lower side of the top plate 5 are started to cut the lower support beam 3. After cutting, the lower support beam 3 falls on the upper side of the first bottom plate 7. The cutting transfer frame 4 needs to be pulled out of the pit 1 by the hoisting equipment.

[0049] Before the cutting and transfer frame 4 is pulled out of the pit 1 by the hoisting equipment, the protective power telescopic rod 1605 is activated. It can drive the adjusting plate 1601 to rotate upward around the support 1603 through the inclined plate 1604, so that the adjusting plate 1601 tilts upward. In this way, if the upper support beam 2 and the cutting and transfer frame 4 overlap in height during the rising process of the cutting and transfer frame 4, the adjusting plate 1601 located on the upper side will contact the upper support beam 2 first and press against the upper support beam 2 to avoid direct collision between the components on the cutting and transfer frame 4 and the upper support beam 2.

[0050] 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.
