Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of drainage engineering construction and the field of environmental protection, and particularly relates to a rainwater inlet edge cutting and removing device and method. BACKGROUND

[0002] In the construction process of carrying out rainwater grate combination transformation and daily maintenance of the urban rainwater collection system, the edge structure of the existing rainwater inlet needs to be removed after cutting the road. Figure 1 As shown in the figure, to cut and remove the edge of the rainwater inlet, vertical cutting needs to be performed on the periphery of the three edges of the rainwater inlet, then the cutting device is extended into the rainwater inlet to perform horizontal cutting on the three edges of the rainwater inlet, and finally the cut edge is removed.

[0003] At present, the construction method for cutting and removing the edge of the rainwater inlet is mostly: combined operation of marble machine, wind pick, edge cutting machine, breaking hammer, milling and other operations, which requires two or more devices to work together. The existing construction method has the following disadvantages:

[0004] 1. Multiple devices are needed for joint construction, the blocking and protection operation area is large, and the road traffic is seriously affected;

[0005] 2. Due to the limitation of the rainwater inlet transformation operation space, manual removal can only be performed from top to bottom on the road surface, the operation efficiency is low, the breaking operation time is long, the urban road traffic efficiency is greatly reduced, and traffic congestion is caused;

[0006] 3. There are problems such as large noise pollution and difficult dust control;

[0007] 4. Due to the influence of manual operation and device vibration, the breaking and removing depth of the rainwater inlet is difficult to unify, the straightness of the edge cutting is difficult to maintain, and the construction complexity of the subsequent operation is increased;

[0008] 5. The top-down operation method will damage the integrity of the target structure, and it is difficult to achieve smooth cutting and separation at a specified depth;

[0009] 6. The construction area uses traditional water spraying dust suppression, which has poor effect, large water consumption and difficult collection, and is easy to cause water accumulation on the surrounding roads.

[0010] Therefore, in order to effectively improve the construction efficiency, shorten the operation time, control the environmental noise, suppress the construction dust, realize standardized and unified construction operation, and guarantee the construction quality of the urban rainwater grate transformation and maintenance project, it is urgent to develop a multifunctional integrated collaborative rainwater inlet edge cutting and removing device to realize environment-friendly and efficient operation construction.

[0097] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings.

[0098] As Figure 2 shown, the rainwater inlet edge cutting and removal device provided by the present application comprises:

[0099] The cabinet 1 can be a hollow rectangular cuboid shape with an open lower part for accommodating other equipment of the device, and the closed shell can also prevent dust during construction. The rainwater inlet is generally rectangular, so the cross section of the cabinet 1 can also be rectangular. One side above the cabinet 1 can be fixed with an operation panel 4. The operation panel 4 can have control elements or indicator lights for controlling the start and stop of other equipment of the device. The operation panel 4 below can have an electrical cabinet box 2 embedded in the cabinet 1. The cabinet 1 side has an opening to expose the cabinet door of the electrical cabinet box 2, facilitating maintenance of the electrical cabinet box 2. One side of the cabinet 1 can also have an outlet of the dust extraction pipe 5 extending out of the cabinet. The cabinet 1 above can be fixedly installed with a display 3, which can be connected with a camera 11 (which can be referred to Figure 3 ) inside the cabinet 1, for real-time display of the construction situation inside the cabinet 1.

[0100] As Figure 3As shown, the cabinet body 1 can have a rack 101 composed of multiple ribs inside the shell. The rack 101 serves as the framework of the cabinet body 1, supporting the shell of the cabinet body 1. Four universal wheel assemblies 12 are respectively fixed and connected below the four corners of the rack 101. When the universal wheel assemblies 12 are raised, the lower part of the cabinet body 1 can be raised to facilitate the movement of the device. When the device is moved above the rainwater inlet to be removed, the universal wheel assemblies 12 can be lowered to enable the cabinet body 1 to contact the road surface, ensuring the sealing of the construction environment during construction and preventing dust dispersion. The side of the electric cabinet box 2 is fixed with a water tank 6 to provide water for the water mist spraying equipment. The water mist spraying equipment has multiple spray heads fixed on the rack 101, which take water from the water tank 6 during operation and spray water mist to the working surface to suppress dust dispersion. One or more cameras 11 and lighting lamps are fixed below the ribs at the top of the rack 101 for real-time monitoring of the operation of the device. The two short sides inside the cabinet body 1 are respectively fixed with a first longitudinal cutting assembly 7 and a second longitudinal cutting assembly 8. One long side inside the cabinet body 1 is fixed with a third longitudinal cutting assembly 9, and the other side is fixed with a horizontal cutting assembly 10.

[0101] During construction, the cabinet body 1 completely covers the cutting equipment, preventing the cutting dust from overflowing, while also reducing noise. Compared with the original open-air construction and simple surrounding fence method, the device can greatly reduce the impact of dust and noise on the surrounding environment. By integrating all equipment into the cabinet body 1, the device also greatly reduces the occupation of the construction site, significantly reduces the range of the fence, and prevents the impact of construction on road traffic.

[0102] As shown in the drawings, Figure 4 The first longitudinal cutting assembly 7, the second longitudinal cutting assembly 8, and the third longitudinal cutting assembly 9 have basically the same structure, which can include a longitudinal driving device, a cutting machine frame, a cutting machine, and a horizontal driving device.

[0103] The longitudinal driving device can include a base 711 for fixing the longitudinal cutting assembly to the rack 101. The longitudinal driving device can also include four vertically installed cylindrical first guide columns 704, two of which are fixed at both ends of the base 711, and the first guide columns 704 can have external threads. A first electric push rod 714 can be provided above the first guide columns 704 at both ends of the base 711. The first electric push rod 714 can drive the first guide columns 704 to rotate.

[0104] The cutting machine frame can be a frame shaped like a mouth, which can be composed of a pair of long fixed rods 702 and a pair of cylindrical sliding rods 712. Two first guide sleeves 703 are fixedly installed on the outer side of each fixed rod 702. The inner side of the first guide sleeve 703 can have internal threads. Each first guide sleeve 703 can be sleeved on a first guide column 704 and be threadedly connected with the first guide column 704. When the first electric push rod 714 drives the first guide column 704 to rotate, the cutting machine frame can be moved up and down. The same side of the two fixed rods 702 can have a nut-shaped screw rod support 708.

[0105] The cutting machine can include a first motor 701 and a disc-shaped saw blade 705. The saw blade 705 is vertically installed, and the first motor 701 can drive the saw blade 705 to rotate, which is used for cutting the rainwater inlet in the vertical direction. The cutting machine can also include two second guide sleeves 715, which are respectively located on both sides of the saw blade 705. Each second guide sleeve 715 is sleeved on a sliding rod 712, so that the cutting machine can move horizontally along the sliding rod 712. The cutting machine can also include a nut-shaped third guide sleeve 710. The third guide sleeve 710 can have internal threads. The cutting machine can also include a micro switch 714, which is used for fine adjustment of the position of the saw blade 705 when the cutting machine is in place.

[0106] The horizontal moving device can include a second motor 706, a coupling 707 and a screw rod 709. The second motor 706 can be fixed at one end of a fixed rod 702. The rotating shaft of the second motor 706 can be fixedly connected with the coupling 707. The coupling 707 can be connected with a cylindrical screw rod 709 having external threads. The screw rod 709 passes through two screw rod supports 708 in sequence and remains in a horizontal state. The third guide sleeve 710 can be sleeved on the screw rod 709 and be threadedly connected with the screw rod 709. When the second motor 706 is started, the rotating shaft can drive the coupling 707 to rotate, the coupling 707 can drive the screw rod 709 to rotate, the screw rod 709 rotating can drive the third guide sleeve 710 to move back and forth in the horizontal direction along the screw rod 709, and the third guide sleeve 710 can drive the cutting machine to move back and forth in the horizontal direction.

[0107] The third longitudinal cutting assembly 9 is used for cutting the long side of the rainwater inlet, and the distance that can be horizontally moved is longer than that of the first longitudinal cutting assembly 7 and the second longitudinal cutting assembly 8. Therefore, the length of the screw rod 709 of the third longitudinal cutting assembly 9 is longer than that of the screw rod 709 of the first longitudinal cutting assembly 7 and the second longitudinal cutting assembly 8.

[0108] During operation, the first electric push rod 714 drives the cutting machine frame and the cutting machine to move downward, and the first motor 701 drives the saw blade 705 to rotate and start longitudinal cutting of the rainwater outlet. After reaching the set cutting depth, the first electric push rod 714 stops working; the second motor 706 drives the cutting machine to move horizontally to complete the longitudinal cutting of one side of the rainwater outlet.

[0109] After the longitudinal cutting of the rainwater outlet is completed, the first electric push rod 714 is started again to drive the cutting machine frame and the cutting machine to move upward, so that the saw blade 705 is separated from the rainwater outlet.

[0110] like Figure 5 As shown, the structure of the horizontal cutting assembly 10 is essentially the same as that of the longitudinal cutting assembly, except that the circular saw blade 705 is replaced by a long folding chain saw 1001. Chain saw 1001 is mounted horizontally and driven by a motor to rotate, cutting the gully horizontally. When folded, the length of folding chain saw 1001 is less than the narrow width of the gully. When in operation, the length of the folding chain saw 1001 is equal to the sum of the narrow width of the gully and the thickness of the material to be cut.

[0111] During operation, the first electric push rod 714 drives the cutting machine frame and the cutting machine to move downward, so that the chain saw 1001 reaches the set depth inside the rainwater outlet along the inner side of a narrow side of the rainwater outlet, and the first electric push rod 714 stops working; the first motor 701 drives the chain saw 1001 to rotate and starts to cut the rainwater outlet horizontally; the second motor 706 starts, driving the cutting machine to move horizontally, and the chain saw 1001 first horizontally cuts the narrow side of the adjacent rainwater outlet, and then moves horizontally to horizontally cut the long side of the rainwater outlet, and finally horizontally cuts the narrow side of the other rainwater outlet.

[0112] After the horizontal cutting of the rainwater outlet is completed, the first electric push rod 714 is started again to drive the cutter frame and the cutter to move upward, so that the chain saw 1001 is separated from the rainwater outlet.

[0113] like Figure 6 As shown, the universal wheel assembly 12 may include a fourth guide sleeve 1203 fixed to a lower corner of the frame 101. The fourth guide sleeve 1203 may be in the shape of a nut and have an internal thread. The universal wheel assembly 12 may also include a second electric push rod 1201 and a second guide column 1202. The second guide column 1202 may be cylindrical and have an external thread. One end of the second guide column 1202 may be hinged to the second electric push rod 1201. The other end of the second guide column 1202 is fixedly connected to the universal wheel 1204. The fourth guide sleeve 1203 may be sleeved on the second guide column 1202 and threadedly connected to the second guide column 1202. The second electric push rod 1201 can drive the second guide column 1202 to rotate, driving the universal wheel 1204 to move up and down.

[0114] When working, the universal wheel assembly 12 can be lowered, so that the bottom of the cabinet 1 is higher than the road surface, and the operator can push the device to move; when reaching the appropriate position above the rainwater inlet, the universal wheel assembly 12 is raised, so that the bottom of the cabinet 1 is in contact with the road surface, thereby ensuring the closure of the construction operation area.

[0115] The rainwater inlet edge cutting and removing device provided by the application can also include a dust removal device, and the dust removal pipeline includes four dust removal openings respectively located near the three longitudinal cutting assemblies and the horizontal cutting assembly, and is connected in communication with the dust removal motor and the dust removal pipeline 5 after being converged. A dust storage bag can be connected outside the dust removal pipeline 5 outside the cabinet 1, and the dust removal motor is started to extract the dust in the cabinet 1. The dust removal motor is linked with the longitudinal cutting assembly and the horizontal cutting assembly, and the dust removal motor is automatically started when the cutting starts.

[0116] The water mist spraying equipment in the rainwater inlet edge cutting and removing device has four spraying openings respectively located above the three longitudinal cutting assemblies and the horizontal cutting assembly. The water mist pump takes water from the water tank 6 and is linked with the longitudinal cutting assembly and the horizontal cutting assembly, and is automatically started when the cutting starts, and sprays water mist through the spraying pipe from the four spraying openings.

[0117] The application also provides a method for cutting and removing a rainwater inlet, which is realized based on the rainwater inlet edge cutting and removing device, and the method comprises the following steps:

[0118] Step 1: Ensure that the device is in a movable state, push the device above the rainwater inlet to be removed, and raise the universal wheel assembly 12.

[0119] The movable state of the device is that the universal wheel assembly 12 is in a lowered state, and the bottom of the cabinet 1 is separated from the road surface; the cutting machines in the three longitudinal cutting assemblies and the horizontal cutting assembly are in a raised state, and the saw blade 705 and the chain saw 1001 are not in contact with the road surface.

[0120] Step 2: Operate the three longitudinal cutting assemblies and the horizontal cutting assembly to cut the rainwater inlet longitudinally and horizontally. The cutting sequence can be arbitrarily combined, for example, longitudinal cutting is performed first, and then horizontal cutting is performed, or vice versa. There is also no limitation on the use sequence of the three longitudinal cutting assemblies during longitudinal cutting, and the use sequence can be arbitrarily combined. When cutting is performed, the dust removal device is automatically started to extract the dust generated during cutting from the device; the water mist spraying equipment is also started to spray water mist to the cutting position to reduce dust. The camera 11 transmits the real-time cutting status to the display 3 outside the cabinet 1, and the operator can observe the cutting status in real time.

[0121] The process of longitudinal cutting comprises the following steps:

[0122] Start the first electric push rod 714 to drive the cutting machine frame and the cutting machine to move downward, the first motor 701 drives the saw blade 705 to rotate to start the longitudinal cutting of the rainwater inlet, and when the set cutting depth is reached, stop the first electric push rod 714 from working; the second motor 706 drives the cutting machine to move horizontally, and the longitudinal cutting of one side of the rainwater inlet is completed.

[0123] After the longitudinal cutting is completed, the first electric push rod 714 is started again to drive the cutting machine frame and the cutting machine to move upward, so that the saw blade 705 is separated from the rainwater inlet.

[0124] The process of horizontal cutting includes:

[0125] Start the first electric push rod 714 to drive the cutting machine frame and the cutting machine to move downward, so that the chain saw 1001 reaches the set depth in the rainwater inlet along the inside of one narrow edge of the rainwater inlet, and stop the first electric push rod 714 from working; start the first motor 701 to drive the chain saw 1001 to rotate, and start cutting the rainwater inlet from the horizontal direction; start the second motor 706 to drive the cutting machine to move horizontally, and the chain saw 1001 first cuts the narrow edges of the adjacent rainwater inlets horizontally, then moves horizontally to cut the long edges of the rainwater inlets, and finally cuts the other narrow edges of the rainwater inlets horizontally.

[0126] After the horizontal cutting is completed, the first electric push rod 714 is started again to drive the cutting machine frame and the cutting machine to move upward, so that the chain saw 1001 is separated from the rainwater inlet.

[0127] Step 3: After the cutting is completed, lower the universal wheel assembly 12 to separate the bottom of the cabinet 1 from the road surface, and push the device away from the rainwater inlet. At this time, three edges of the rainwater inlet have been cut and separated, and the cut edges are directly taken out, which completes the cutting edge removal work of the rainwater inlet.

[0128] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and they should be covered in the scope of the claims of the present application.
