[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The top plate of the present invention can move up and down driven by the height adjustment mechanism. When the top plate is in the lower transfer state, the top plate is located on the upper side of the lower support beam, and the first bottom plate is located on the lower side of the lower support beam. The cutting device on the top plate can cut the lower support beam between the two, cut off the lower support beam at the corresponding area, and the cut lower support beam falls to the upper side of the first bottom plate. When the top plate is converted to the upper transfer state, the top plate is located on the upper side of the upper support beam, and the position of the second bottom plate is adjusted by the telescopic unit to move the second bottom plate to the lower side of the upper support beam.

[0019] 2. According to the present invention, before the cutting and transfer frame is pulled out of the foundation pit by the lifting equipment, the protective power telescopic rod is started, which can drive the adjustment plate to rotate upward around the support through the inclined plate, so that the adjustment plate is tilted upward. In this way, during the rising process of the cutting and transfer frame, if the upper support beam and the upper and lower heights of the cutting and transfer frame overlap, the adjustment plate located on the upper side will first contact the upper support beam, and then it will rest on the upper support beam to avoid direct collision between the components on the cutting and transfer frame and the upper support beam, thereby protecting the components inside the cutting and transfer frame and preventing the upper support beam from loosening prematurely due to the collision with the cutting and transfer frame.

At the same time, in the above-mentioned moving method, during the process of cutting the lower support beam, the lower support beam can be moved to an area at a certain distance from the upper support beam through the moving component, so that the upper support beam can be avoided during the upward movement of the top plate to avoid collision.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 9 A cutting and transporting device for underground construction includes a foundation pit 1, an upper support beam 2, a lower support beam 3, and a cutting and transporting frame 4. A top plate 5 is arranged on the cutting and transporting 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 transport state and a lower transport state;

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

[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, and the first bottom plate 7 is located on the lower side of the lower support beam 3. In this way, 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 therebetween, cut off the lower support beam 3 at the corresponding area, and the cut lower support beam 3 falls to the upper side of the first bottom plate 7. The cutting and transporting frame 4 is pulled upward by the lifting rope to move the cut lower support beam 3 away from the foundation pit 1. By repeating the above operation, the entire lower support beam 3 can be transferred away, and then the cutting and transfer work of the upper support beam 2 can be carried out.

[0035] The height of the top plate 5 is adjusted by the height adjustment mechanism 6 to convert it into the upper transfer state. At this time, the top plate 5 is located on the upper side of the upper support beam 2. The position of the second bottom plate 8 is adjusted by the telescopic unit 9 to move the second bottom plate 8 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, the upper support beam 2 is cut off and falls to the upper side of the second bottom plate 8. The cutting and transfer frame 4 is pulled upward by the lifting rope, and the cut upper support beam 2 can be taken out from the foundation pit 1, thereby completing the cutting and removal of the upper support beam 2.

[0036] In a further embodiment, the second bottom plate 8 is connected to the telescopic unit 9, and the telescopic unit 9 can move the second bottom plate 8 to the lower side of the upper support beam 2 and also remove it from the lower side of the upper support beam 2. At this time, the second bottom plate 8 does not hinder the upper and lower movements of the top plate 5. Figure 5 The telescopic unit 9 is installed on a side of the cutting and transporting frame 4 away from the upper supporting beam 2, and a tripod is installed at the lower end of the telescopic unit 9.

[0037] In order to cut and transport the upper support beam 2 and the lower support beam 3 out of the foundation pit 1, a cutting device 10 is arranged 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 cooperates with the cutting lifting device 11 to cut off the corresponding upper support beam 2 and the lower support beam 3, so that the upper support beam 2 and the lower support beam 3 can be transferred in sections.

[0038] In order to prevent the upper support beam 2 or the lower support beam 3 from shaking during the process of the cutting device 10 cutting the above two beams, a pressure plate 12 is installed on the lower side of the top plate 5. The pressure plate 12 is set in an L shape. The pressure plate 12 is 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 started to drive the pressure plate 12 to move downward and fix the upper support beam 2 or the lower support beam 3, so that any one of the above two can remain stable during the cutting process, thereby ensuring stability and safety performance during the cutting process.

[0039] The cutting and transporting frame 4 can move inside the foundation pit 1. After the lifting equipment connected with the lifting rope sends the cutting and transporting frame 4 into the foundation pit 1, the moving assembly 14 connected to the cutting and transporting frame 4 can move it to a suitable position. There is no need for lifting equipment to send it to the cutting position. There are upper support beams 2 and lower support beams 3 near the cutting position. It is necessary to avoid collision between the cutting and transporting frame 4 and the upper support beams 2 and lower support beams 3 when directly lifting it to the position. By moving the cutting and transporting frame 4 to the cutting position through the moving assembly 14, the difficulty of lifting by the lifting equipment operator can be reduced. The moving assembly 14 is provided at the bottom of the cutting and transporting frame 4.

[0040] Specifically, the mobile component 14 includes a caster 1401, two casters 1401 are provided, and the two casters 1401 are arranged in parallel, the rotating shaft installed on the upper end of the caster 1401 is inserted into the support seat 1402, the support seat 1402 is installed on the lifting plate 1405, the caster 1401 and the support seat 1402 are rotatably connected through the rotating shaft and the bearing, the outer side of the rotating shaft is sleeved with a transmission wheel 1404, the two transmission wheels 1404 on the two casters 1401 are connected through a transmission belt 1403, and the transmission belt 1403 is a type with teeth, so that the two casters 1401 can rotate synchronously when rotating, one of the casters 1401 is connected to a driving motor, and the driving motor is used to drive the caster 1401 connected thereto to rotate;

[0041] The driving motor can drive the rotating shaft and caster 1401 to rotate, and the two casters 1401 rotate synchronously through the transmission wheel 1404 and the transmission belt 1403, so that the direction of the caster 1401 can be adjusted. The caster 1401 has a power function. The direction of the caster 1401 changes and its moving direction also changes accordingly. The moving component 14 composed in this way can allow the cutting and transfer frame 4 to move to multiple areas in the foundation pit 1. At the same time, in the above-mentioned moving method, during the process of cutting the lower support beam 3, the lower support beam 3 can be moved to an area at a certain distance from the upper support beam 2 through the moving component 14, so that the top plate 5 can avoid the upper support beam 2 during the upward movement to avoid collision.

[0042] More specifically, the lifting plate 1405 is located in the lifting slot in the cutting transfer frame 4, and the lifting plate 1405 is connected to the buffer 1406. The buffer 1406 cooperates with the casters 1401 to allow the cutting transfer frame 4 to move stably when moving without load or driving the upper support beam 2 and the lower support beam 3 after cutting.

[0043] In order to facilitate the connection between the cutting and transporting frame 4 and the lifting rope and lifting equipment, a plurality of transporting lifting rings 15 are provided on the upper side of the cutting and transporting frame 4 .

[0044] In the process of dismantling the upper support beam 2 and the lower support beam 3 in the foundation pit 1, in order to prevent the foundation pit 1 from collapsing, the lower support beam 3 located on the lower side is usually dismantled first. After the lower support beam 3 is cut off, it is easy to collide with the upper support beam 2 located on its upper side during its movement to the upper side. In order to avoid the collision, a protective component 16 is arranged above the cutting and transporting frame 4. The protective component 16 includes an adjusting plate 1601, and the adjusting plate 1601 is arranged on a support 1603. The support 1603 is arranged on the upper side of the top plate 5. Two parallel distributed protective plates 1602 are installed on the upper side of the adjusting plate 1601, and an inclined plate 1604 is arranged 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 adopts a hydraulic cylinder. After a section of the lower support beam 3 is cut off, it needs to be transported away by a lifting rope and lifting equipment. Before transportation, the protective power telescopic rod 1605 needs to be started, which can drive the adjustment plate 1601 to rotate upward around the support 1603 through the inclined plate 1604, so that the adjustment plate 1601 can tilt upward. In this way, during the rising process of the cutting and transfer frame 4, if there is a partial overlap between the upper support beam 2 and the cutting and transfer frame 4 in the upper and lower heights, the adjustment plate 1601 located on the upper side will first contact the upper support beam 2, and then it will rest on the upper support beam 2 to prevent other components on the cutting and transfer frame 4 from directly colliding with the upper support beam 2.

[0046] Working principle:

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

[0048] The cutting and transferring frame 4 first moves 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 and 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 to the upper side of the first bottom plate 7. The cutting and transferring frame 4 needs to be pulled out of the foundation pit 1 by hoisting equipment.

[0049] Before the cutting and transfer frame 4 is pulled out of the foundation pit 1 by the lifting equipment, the protective power telescopic rod 1605 is started, which can drive the adjustment plate 1601 to rotate upward around the support 1603 through the inclined plate 1604, so that the adjustment plate 1601 is tilted upward. In this way, during the rising process of the cutting and transfer frame 4, if the upper support beam 2 and the cutting and transfer frame 4 partially overlap in height, the adjustment plate 1601 located on the upper side will first contact the upper support beam 2, and then it will rest on 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 present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
