Description

Technical Field

[0001] The present application belongs to the field of drainage engineering construction technology and environmental protection, and specifically relates to a rainwater inlet trimming and removal device and method. Background Art

[0002] During the construction process of the rainwater grating horizontal and vertical combination transformation and daily maintenance of the urban rainwater collection system, it is necessary to remove the edge structure of the existing rainwater outlet after cutting the road. Figure 1 As shown, to trim and remove the rainwater outlet, firstly, vertical cutting needs to be performed on the periphery of the three sides of the rainwater outlet, and then the cutting equipment is extended into the rainwater outlet to perform horizontal cutting on the three sides of the rainwater outlet, and finally the cut edge strips are removed.

[0003] At present, the construction methods for trimming and dismantling rainwater inlets are mostly: marble machine, pneumatic pick, trimming machine, breaker hammer, milling planer and other joint operations, which require more than two types of equipment to work together. The existing construction methods have the following disadvantages:

[0004] 1. It requires joint construction of multiple equipments, and the barrier operation area is large, which seriously affects the road traffic;

[0005] 2. Limited by the working space of the stormwater outlet renovation, manual demolition can only be carried out by top-down demolition on the road surface, which has low working efficiency and long demolition time, greatly reducing the traffic efficiency of urban roads and causing traffic congestion;

[0006] 3. There are environmental problems such as high noise pollution and difficulty in controlling dust;

[0007] 4. Affected by manual operation and equipment vibration, it is difficult to unify the depth of the rainwater outlet demolition and maintain the straightness of the cutting edge, which increases the complexity of subsequent construction operations;

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

[0009] 6. The traditional water sprinkling method in the construction area has poor dust suppression effect, consumes a lot of water and is difficult to collect, which can easily cause water accumulation in surrounding roads.

[0010] Therefore, in order to effectively improve construction efficiency, shorten operation time, control environmental noise, suppress construction dust, realize standardized and unified construction operations, and ensure the construction quality of urban rainwater grating renovation and maintenance projects, it is urgently necessary to develop a multifunctional integrated and coordinated rainwater outlet trimming and removal device to achieve environmentally friendly and efficient operation and construction.

[0097] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

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

[0099] The cabinet 1 may be in the shape of a hollow rectangular parallelepiped with an opening at the bottom, which is used to accommodate other equipment of the device. Its closed shell can also prevent dust during construction. The rainwater outlet is generally rectangular, so the cross-section of the cabinet 1 may also be rectangular. An operation panel 4 may be fixed to one side above the cabinet 1. The operation panel 4 may have control elements or indicator lights for controlling the start, stop and operation of other equipment of the device. An electric cabinet box 2 embedded in the cabinet 1 may be provided below the operation panel 4. The side of the cabinet 1 has an opening, exposing the cabinet door of the electric cabinet box 2, which is convenient for maintenance of the electric cabinet box 2. One side of the cabinet 1 may also have an outlet for a dust extraction duct 5 extending out of the cabinet. A display 3 may be fixedly installed above the cabinet 1, and the display 3 may be connected to a camera 11 inside the cabinet 1 (see FIG. 1 ). Figure 3 ) is connected to display the construction status inside the cabinet 1 in real time.

[0100] like Figure 3As shown, the cabinet 1 shell may have a frame 101 composed of multiple ribs inside. The frame 101 serves as the skeleton of the cabinet 1 and supports the shell of the cabinet 1. A liftable universal wheel assembly 12 is fixedly connected to the four corners below the frame 101. When the universal wheel assembly 12 is raised, the lower part of the cabinet 1 can be raised to facilitate the movement of the device. When the device is moved above the rainwater outlet to be cut off, the universal wheel assembly 12 can be lowered so that the cabinet 1 can contact the road surface, ensuring the sealing of the construction environment during construction and preventing dust from spreading. A water tank 6 is fixed on the side of the electrical cabinet 2 to provide a water source for the water mist spraying equipment. The water mist spraying equipment has multiple spray heads fixed on the frame 101. When working, water is taken from the water tank 6 and water mist is sprayed onto the working surface to inhibit dust diffusion. One or more cameras 11 and lighting lamps are fixed below the top ribs of the frame 101 to monitor the operation of the device in real time. The first longitudinal cutting assembly 7 and the second longitudinal cutting assembly 8 are respectively fixedly installed on the two short sides inside the cabinet 1. The third longitudinal cutting assembly 9 is fixedly installed on one long side inside the cabinet 1, and the horizontal cutting assembly 10 is fixedly installed on the other side.

[0101] During construction, the cabinet 1 completely covers the cutting equipment, which can prevent the dust from cutting from overflowing and reduce noise. Compared with the previous open-air construction and simple enclosure around it, the impact of dust and noise on the surrounding environment can be greatly reduced. This device integrates all equipment into the cabinet 1, which also greatly reduces the occupation of the construction site, greatly reduces the scope of the enclosure, and prevents the impact of construction on road traffic.

[0102] like Figure 4 As shown, the structures of the first longitudinal cutting assembly 7, the second longitudinal cutting assembly 8 and the third longitudinal cutting assembly 9 are basically the same, and may include: a longitudinal driving device, a cutting machine frame, a cutting machine and a horizontal driving device.

[0103] The longitudinal drive device may include a base 711 for fixing the longitudinal cutting assembly to the frame 101. The longitudinal drive device may also include four vertically mounted cylindrical first guide pillars 704, two of which are fixed at both ends of the base 711 in a group, and the first guide pillars 704 may have external threads. A first electric push rod 714 may be respectively disposed above the first guide pillars 704 at both ends of the base 711. The first electric push rod 714 may drive the first guide pillar 704 to rotate.

[0104] The frame of the cutting machine can be a square-shaped frame, which can be composed of a pair of long strip-shaped 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 an internal thread. Each first guide sleeve 703 can be sleeved on a first guide column 704 and 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. A nut-shaped screw support seat 708 can be provided on the same side of the two fixed rods 702.

[0105] The cutting machine may include a first motor 701 and a disc-shaped saw blade 705. The saw blade 705 is installed vertically, and the first motor 701 can drive the saw blade 705 to rotate, so as to cut the rainwater outlet in the vertical direction. The cutting machine may 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 slide bar 712, so that the cutting machine can move horizontally along the slide bar 712. The cutting machine may also include a nut-shaped third guide sleeve 710. The third guide sleeve 710 may have an internal thread. The cutting machine may also include a micro switch 714, which is used to fine-tune the position of the saw blade 705 when the cutting machine is in place.

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

[0107] The third longitudinal cutting component 9 is used to cut the long side of the rainwater outlet. Its horizontal movable distance is longer than the horizontal movable distance of the first longitudinal cutting component 7 and the second longitudinal cutting component 8. Therefore, the length of the screw rod 709 of the third longitudinal cutting component 9 is longer than the length of the screw rod 709 of the first longitudinal cutting component 7 and the second longitudinal cutting component 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 basically the same as that of the longitudinal cutting assembly, except that the disc-shaped saw blade 705 is replaced by a long folding chain saw 1001. The chain saw 1001 is installed horizontally, and the motor drives the chain saw 1001 to rotate to cut the rainwater outlet from the horizontal direction. When the folding chain saw 1001 is folded, the length is less than the narrow side width of the rainwater outlet, and when it is open, the length is equal to the sum of the narrow side width of the rainwater outlet and the thickness to be cut in the rainwater outlet.

[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 in the rain outlet along the inner side of a narrow side of the rain 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 rain outlet horizontally; the second motor 706 starts, driving the cutting machine to move horizontally, and the chain saw 1001 first horizontally cuts the adjacent narrow side of the rain outlet, and then moves horizontally to horizontally cut the long side of the rain outlet, and finally horizontally cuts the narrow side of the other rain outlet.

[0112] After the horizontal 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 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 corner below 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 may drive the second guide column 1202 to rotate, thereby driving the universal wheel 1204 to move up and down.

[0114] During operation, 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 it reaches a suitable position above the rainwater outlet, the universal wheel assembly 12 is raised so that the bottom of the cabinet 1 contacts the road surface, thereby ensuring the closure of the construction area.

[0115] The rainwater inlet trimming and removal device provided in the present application may also include dust removal equipment, and the dust extraction pipeline includes four dust extraction ports, which are respectively located near the three longitudinal cutting components and the horizontal cutting component, and are connected to the dust extraction pipeline 5 through the dust extraction motor after convergence. A dust collection bag can be connected to the outside of the dust extraction pipeline 5 outside the cabinet 1, and the dust in the cabinet 1 can be extracted after the dust extraction motor is started. The dust extraction motor is linked with the longitudinal cutting component and the horizontal cutting component, and the dust extraction motor is automatically started when cutting starts.

[0116] The water mist spraying equipment in the rainwater outlet trimming and removal device has four spray outlets, which are respectively located above the three longitudinal cutting components and the horizontal cutting component. The spray water pump takes water from the water tank 6 and is linked with the longitudinal cutting component and the horizontal cutting component. It starts automatically when cutting starts and sprays from the four spray outlets through the spray pipe.

[0117] The present application also provides a method for trimming and removing a rainwater inlet, which is implemented based on the above-mentioned rainwater inlet trimming and removing device, and the method comprises:

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

[0119] The movable state of the device is specifically as follows: the universal wheel assembly 12 is in a lowered state, and the bottom of the cabinet 1 is off the road surface; the cutters 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 components and the horizontal cutting components to cut the rainwater outlet longitudinally and horizontally. The order of cutting can be arbitrarily combined, for example, longitudinal cutting first and then horizontal cutting, or vice versa. There is no restriction on the order of using the three longitudinal cutting components during longitudinal cutting, and they can be combined arbitrarily. During the cutting operation, the dust removal equipment automatically starts to extract the dust generated by the cutting; the water mist spraying equipment is also started at the same time to spray water mist at 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 situation in real time.

[0121] The longitudinal cutting process includes:

[0122] Start the first electric push rod 714 to drive 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, stop the first electric push rod 714; the second motor 706 drives the cutting machine to move horizontally to complete the longitudinal cutting of one side of the rainwater outlet.

[0123] After the longitudinal cutting 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 saw blade 705 is separated from the rainwater outlet.

[0124] The horizontal cutting process 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 inside the rainwater outlet along the inner side of a narrow side of the rainwater outlet, and stop the first electric push rod 714; start the first motor 701, drive the chain saw 1001 to rotate, and start cutting the rainwater outlet from the horizontal direction; start the second motor 706 to drive the cutting machine to move horizontally, the chain saw 1001 first horizontally cuts the adjacent narrow side of the 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.

[0126] After the horizontal cutting 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.

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

[0128] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application is described in detail with reference to the embodiments, a person skilled in the art should understand that any modification or equivalent replacement of the technical solution of the present application does not depart from the spirit and scope of the technical solution of the present application and should be included in the scope of the claims of the present application.
