Description

Technical Field

[0001] The invention relates to the field of construction engineering, and more specifically, to a device for dismantling and modifying an auxiliary structure used for a large railway station building on a subway station cover. Background Art

[0002] With the rapid development of my country's high-speed railways, the construction of large railway stations has shown a sharp growth trend. More and more large-scale railway integrated transportation hubs integrate subways, buses, and taxis, and are designed, constructed, and put into use at the same time, achieving smooth integration and greatly facilitating passenger travel.

[0003] Because the reserved entrances and exits and wind shelters of the existing operating subway overlap with the foundation of the newly built station building, the attached entrances and exits and wind shelters need to be demolished. When demolishing the side walls of the subway, manual handheld electric picks and cutting machines are usually used to break them. Commonly used cutting machines are mostly rope saws, but when the rope saws are cutting reinforced concrete side walls, water needs to be sprayed at the cutting point to cool and reduce dust on the diamond saw rope. However, this will also cause the saw rope segment removed from the concrete to be attached with a mixture of concrete slag and water. When passing the drive wheel, because the mixture is between the saw rope and the drive wheel, the soft mixture will cause sliding between the two, and sliding friction will be generated between the saw rope and the drive wheel. After long-term use, it is very easy to cause the drive wheel to be severely worn. Summary of the invention

DETAILED DESCRIPTION

[0029] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only intended to enable those skilled in the art to better understand and implement the subject matter described herein. In addition, the features described relative to some examples may also be combined in other examples.

[0030] like Figure 1-Figure 4 As shown, a device for dismantling and modifying ancillary structures for a large railway station building on a subway station roof comprises a linear moving mechanism, a moving platform 103 connected to the linear moving mechanism, an angle adjustment mechanism connected to the moving platform 103, a cutting mechanism connected to the angle adjustment mechanism, a cleaning mechanism 4 connected to the cutting mechanism, and a drying mechanism 5 connected to the cleaning mechanism 4;

[0031] The linear motion mechanism includes a sliding track and a linear motion component disposed on the sliding track. The mobile platform 103 is slidably connected to the sliding track. The linear motion component is used to drive the mobile platform 103 to move along the sliding track.

[0032] The angle adjustment mechanism includes an adjustable support assembly detachably connected to the mobile platform 103 and an angle adjustment assembly connected between the adjustable support assembly and the mobile platform 103, the cutting mechanism is detachably connected to the adjustable support assembly, and the angle adjustment assembly is used to adjust the angle between the cutting mechanism and the horizontal plane;

[0033] The cutting mechanism includes a circulating rotating assembly and a diamond saw rope 306 arranged on the circulating rotating assembly. The circulating rotating assembly is used to drive the end-to-end connected diamond saw rope 306 to circulate. The end-to-end connected diamond saw rope 306 passes through the cleaning mechanism 4 and the drying mechanism 5 in sequence during the circulatory rotation.

[0034] The cleaning mechanism 4 includes a limiting component, an annular liquid guiding component and an annular reflux component arranged on the limiting component, a wrapped flushing component movably connected to the limiting component, and a counterweight block 406 connected to the wrapped flushing component. The liquid inlet end and the liquid outlet end of the wrapped flushing component are respectively connected to the annular liquid guiding component and the annular reflux component. When the angle adjustment component adjusts the angle between the cutting mechanism and the horizontal plane, the gravity of the counterweight block 406 drives the wrapped flushing component to rotate around the central axis of the limiting component and makes its liquid inlet end and liquid outlet end always perpendicular to the horizontal plane.

[0035] It should be noted that when cutting and demolishing the concrete reinforced concrete side wall to be demolished, the area to be cut is determined according to the design parameters, and then a manual hand-held electric pick is used to open holes for passing the saw rope at the edge of the area to be cut. The position and number of the holes are set based on the area to be cut. For example, for a quadrilateral area, only holes need to be set at the four corner points. This cutting path is the shortest cutting path. Then the two ends of the saw rope are respectively passed through two adjacent holes, and then connected to a complete circle on the circulating rotating component. Then, the saw rope is driven to move along the circle by the circulating rotating component, so as not to The reinforced concrete side wall is continuously ground and cut. At the same time, the linear moving component drives the mobile platform 103 to drive the circular rotating component to move slowly in the direction away from the wall, so as to continuously adapt the cutting process of the saw rope on the wall, that is, the change of the rope position after the saw rope cuts into the wall, so that the saw rope can always be in a taut state. If there is a cutting path with an inclination when cutting into a polygon, the angle between the adjustable support component and the horizontal plane can be adjusted through the angle adjustment component, so that the entire circular rotating component and the saw rope can cut the wall at a set inclination angle, that is, adapt to different The cutting path is controlled by the wrap-around flushing component. When the angle tilt adjustment occurs, the wrap-around flushing component, under the influence of the counterweight block 406, can always keep its water spraying point above the saw rope and the sewage discharge point below the rope saw to prevent the sewage from continuously affecting the saw rope. When the saw rope cuts the reinforced concrete side wall, water is required to cool the cutting point and reduce dust. When the saw rope moves out of the wall, a mixture of slag dust and water adheres to the saw rope. When passing through the wrap-around flushing component, clean water is continuously added to the wrap-around flushing component through the annular liquid guide component, which can effectively flush the surface of the saw rope, thereby removing the adhering mixed dust. The washed mixture is washed away, and the washed mixture is collected and processed in a centralized manner through the annular reflux component, thereby reducing the impact on the equipment and the environment around the equipment. After the rinsed saw rope passes through the drying mechanism 5, the surface can be dried. The drying method adopts a combination of air drying and wiping. The water stains attached to the saw rope can be dried without increasing the temperature of the saw rope, thereby effectively preventing the mixture or water from existing between the saw rope and the rotating component, preventing the wear caused by sliding friction between the saw rope and the circulating rotating component, and effectively improving the stability and service life of the equipment.

[0036] Among them, Figure 1 As shown, the sliding track includes a support frame 101 and a plurality of position-limiting guide rods 102 fixedly connected to the support frame 101, and the plurality of position-limiting guide rods 102 are all slidably connected to a mobile platform 103, and a first connecting bracket 106 is connected to the mobile platform 103;

[0037] The linear motion assembly includes a first motor 104 fixedly connected to the support frame 101 and a screw rod 105 movably connected to the support frame 101 . One end of the screw rod 105 is connected to the output shaft end of the first motor 104 , and the screw rod 105 is threadedly connected to the mobile platform 103 .

[0038] It should be noted that, as described above, during the cutting process, the moving platform 103 is driven away from the wall by the linear moving assembly. Specifically, the first motor 104 is used to drive the screw rod 105 to rotate. When the screw rod 105 rotates, the moving platform 103 threadedly connected thereto can be driven to slide along the limiting guide rod 102. The length direction of the limiting guide rod 102 points to the wall to be cut, so as to adapt to the cutting position change of the saw rope by adjusting the position change of the moving platform 103 and the wall.

[0039] The linear motion component may use not only the first motor 104 and the lead screw 105 , but also a pneumatic cylinder or a hydraulic cylinder.

[0040] Among them, Figure 1 As shown, the adjustable support assembly includes a second connecting bracket 201 detachably connected to the first connecting bracket 106 and a third connecting bracket 202 hinged on the second connecting bracket 201, and the cutting mechanism is detachably connected to the third connecting bracket 202;

[0041] The angle adjustment assembly includes an electric telescopic rod 203 connected between the third connecting bracket 202 and the mobile platform 103 , and two ends of the electric telescopic rod 203 are respectively hinged to the third connecting bracket 202 and the mobile platform 103 .

[0042] It should be noted that, as mentioned above, when the tilt setting angle of the adjustable support assembly is adjusted by the angle adjustment assembly, the third connecting bracket 202 is driven to rotate around the hinge with the second connecting bracket 201 by controlling the telescopic length of the electric telescopic rod 203, and the rotation angle is related to the telescopic length of the electric telescopic rod 203.

[0043] Among them, Figure 1 As shown, the circulating rotating component includes a mounting frame 301 detachably connected to the third connecting bracket 202, a second motor 302 fixedly connected to the mounting frame 301, a driving wheel 303 movably connected to the mounting frame 301 and a plurality of fixed tensioning wheels 304 and an adjustable tensioning wheel 305 installed on the mounting frame 301, and the output shaft end of the second motor 302 is connected to the axle of the driving wheel 303.

[0044] It should be noted that when the saw rope is driven to cut the wall, the driving wheel 303 is driven to rotate by the second motor 302. Driven by the driving wheel 303, the saw rope forming a closed loop can be driven to move back and forth. The tension of the saw rope can be adjusted by a number of fixed tension wheels 304 and an adjustable tension wheel 305.

[0045] Among them, Figure 4 As shown, the limiting assembly includes a square limiting rod 401 fixedly connected to the mounting frame 301, a first connecting plate 402 fixedly connected to one end of the square limiting rod 401, a first limiting ring body 403 fixedly connected to the first connecting plate 402, and a plurality of clamping ring bodies 4030 connected to the inner circumferential surface of the first limiting ring body 403;

[0046] The annular liquid guiding component includes an annular liquid guiding groove 4031 provided on the inner circumference of the first limiting ring body 403, and a liquid guiding tube 4033 connected to the outer circumference of the first limiting ring body 403, one end of the liquid guiding tube 4033 passes through the first limiting ring body 403 and communicates with the annular liquid guiding groove 4031;

[0047] The annular reflux assembly includes an annular reflux groove 4032 provided on the inner circumference of the first limiting ring body 403 , and a reflux pipe 4034 connected to the outer circumference of the first limiting ring body 403 . One end of the reflux pipe 4034 passes through the first limiting ring body 403 and is connected to the annular reflux groove 4032 .

[0048] The wrapped flushing assembly includes a movable tube body 404, a cleaning chamber 4040 and an air-drying chamber 4041 arranged in the movable tube body 404, a liquid guiding cavity 4042 and a reflux hole 4045 arranged on the outer circumferential surface of the movable tube body 404, a liquid collecting groove 4044 and a plurality of liquid spraying holes 4043 arranged on the inner wall of the cleaning chamber 4040, and a plurality of annular brush bodies 405 connected to the inner wall of the cleaning chamber 4040. A diversion channel is provided inside the movable tube body 404, and the plurality of liquid spraying holes 4043 are all connected to the liquid guiding cavity 4042 through the diversion channel. The liquid guiding cavity 4042 is connected to the annular liquid guiding groove 4031, and the cleaning chamber 4040 is connected to the annular reflux groove 4032 through the reflux hole 4045. The movable tube body 404 is provided with an annular clamping groove matching the clamping ring body 4030.

[0049] It should be noted that, as mentioned above, when the saw rope passes through the wrapped flushing assembly, the clean water introduced from the liquid guide tube 4033 flows through the annular liquid guide groove 4031 and the liquid guide cavity 4042 in sequence, and then is sprayed out from the liquid spray hole 4043. A plurality of liquid spray holes 4043 are distributed in an arc shape on the inner wall of the cleaning chamber 4040. Due to the gravity of the counterweight block 406, the counterweight block 406 is always at the position closest to the ground. The liquid spray holes 4043 are distributed above and on the side of the saw rope, so that the saw rope can be flushed, and the annular brush body 405 can be used to brush the saw rope, which can effectively improve the cleaning efficiency and cleanliness of the saw rope, and the flushing The sewage is gathered at the bottom of the cleaning chamber 4040 and flows from the collecting tank 4044 to the reflux hole 4045. The sewage flows into the annular reflux groove 4032 from the reflux hole 4045 and is extracted by the reflux pipe 4034, so that the sewage can be centrally recycled. In order to adapt to the change of the cutting path, that is, when the cutting mechanism is deflected at an angle, the gravity of the counterweight block 406 can make the entire movable tube body 404 rotate adaptively, so that the counterweight block 406 is always in the lowest position, that is, the liquid guiding cavity 4042 and the reflux hole 4045 are always in a state perpendicular to the horizontal plane, so that the saw rope cleaning process is not affected.

[0050] Among them, Figure 3 and Figure 4 As shown, the drying mechanism 5 includes a reciprocating telescopic pump air assembly connected to one end of the wrapped flushing assembly, an injection assembly and an expandable wiping assembly arranged inside the wrapped flushing assembly, and the injection assembly and the expandable wiping assembly are both connected to the reciprocating telescopic pump air assembly.

[0051] The reciprocating pump air assembly includes a second connecting plate 501 slidably connected to the square limit rod 401, a second limit ring body 502 connected to the second connecting plate 501, a movable ring body 503 movably connected to the second limit ring body 502, a first telescopic bellows 504 and a second telescopic bellows 505 connected between the movable ring body 503 and the movable tube body 404, a third motor fixedly connected to the mounting frame 301, and a reciprocating screw 508 connected to the output shaft end of the third motor. A slider matching the reciprocating screw 508 is provided on the second connecting plate 501, and a sealed pump air chamber is formed between the movable ring body 503, the first telescopic bellows 504, the movable tube body 404 and the second telescopic bellows 505.

[0052] The jet assembly includes a ventilation cavity 506 disposed inside the movable tube body 404 and a plurality of jet holes 507 disposed on the inner wall of the air-drying chamber 4041 . The plurality of jet holes 507 are all connected to the sealed pump air chamber through the ventilation cavity 506 .

[0053] It should be noted that, as mentioned above, the saw rope cleaned in the cleaning chamber 4040 is moved to the air-drying chamber 4041, and the reciprocating screw 508 is driven to rotate by the third motor. The reciprocating screw 508 can drive the second connecting plate 501 to continuously move back and forth towards and away from the movable tube body 404. In this process, whether approaching or moving away, the volume of the sealed pump air chamber formed between the movable ring body 503, the first telescopic bellows 504, the movable tube body 404 and the second telescopic bellows 505 can change, and the second connecting plate 501 can move back and forth. When the connecting plate 501 is close to the movable tube body 404, the internal volume of the sealed pump air chamber decreases, generating positive pressure, squeezing out the gas inside the sealed pump air chamber, and the gas flows through the ventilation cavity and is ejected from the jet hole 507. The saw rope with clean water attached to it can be air-dried during the flow of gas. When the second connecting plate 501 is away from the movable tube body 404, the internal volume of the sealed pump air chamber increases, generating positive pressure, thereby drawing external gas into the sealed pump air chamber, and also generating airflow flowing through the saw rope, thereby preventing water stains from affecting the space between the saw rope and the driving wheel 303.

[0054] Among them, Figure 4 As shown, the expandable wiping assembly includes an annular capsule 509 connected to the inner wall of the air-drying chamber 4041 , the outer surface of the annular capsule 509 is provided with a flexible water-absorbing layer, and the internal space of the annular capsule 509 is connected to the sealed pump air chamber through the ventilation cavity 506 .

[0055] It should be noted that in order to further improve the degree of drying of water stains on the surface of the saw rope, the annular capsule 509 can be intermittently expanded during the change of the sealing pump air chamber as mentioned above. Specifically, the volume of the sealing pump air chamber is reduced, and the gas is discharged into the ventilation cavity 506. The ventilation cavity 506 connected to the annular capsule 509 is a separate channel, so that a part of it enters the annular capsule 509, causing the annular capsule 509 to bulge. During the bulging time period, two-thirds of the middle position of the connecting section between adjacent diamond cutting parts on the saw rope contacts the flexible water absorption layer on the annular capsule 509, and then the volume of the sealing pump air chamber is increased, and the gas inside the annular capsule 509 is extracted, so that the diamond cutting part only contacts the flexible water absorption layer when passing through the annular capsule 509, but does not contact the annular capsule 509, which can effectively reduce the loss of the annular capsule 509 caused by the contact between the diamond cutting part and the annular capsule 509.

[0056] The present embodiment is described above, but the present embodiment is not limited to the above-mentioned specific implementation manner. The above-mentioned specific implementation manner is merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, which are all within the protection of the present embodiment.
