[0001] The invention relates to the technical field of rail transit, and in particular to a cleaning device for urban rail transit vehicles. Background Art

[0002] Subway floor renovation is a complex job involving multiple steps, aimed at restoring the flatness and beauty of the floor while ensuring the safety and comfort of passengers. After the removal and polishing of the old film, the cleaning stage is the key to ensure the next stage of re-coating goes smoothly.

[0003] The first task of cleaning the floor is to remove the debris and dust left by the grinding operation. Subsequently, the detergent and water are mixed in proportion, the floor is thoroughly rinsed, and at the same time, a large-scale floor washing equipment is used for in-depth scrubbing to ensure that old glue, grease and stubborn dirt are completely removed. However, when dealing with the area under the subway seats, due to the large size of the single floor washing machine and the difficulty in entering, it is still necessary to rely on manual handheld brushes for wiping, which not only requires workers to bend over frequently, but also difficult to fully reach due to the narrow space under the seat, thereby affecting the cleaning effect.

[0013] Beneficial effects of the present invention: 1. In the present invention, a person can stand and hold the hand-held rod to drag the machine body to move, thereby driving the first scrubbing plate and the second scrubbing plate to move and clean the dead corner area of ​​the floor under the seat, without manually bending over to drag and scrub the floor under the seat, and the first scrubbing plate and the second scrubbing plate reciprocate and the movement directions of the two are always opposite, which means that when the machine body stops moving, the reciprocating movement can scrub the floor of an area back and forth, and when the person drives the machine body to move by the hand-held rod, it is assumed that it moves from the second scrubbing plate to the first scrubbing plate. During the movement, the floor of a certain area has just been scrubbed from left to right by the first scrubbing plate, and will be scrubbed from right to left by the second scrubbing plate immediately after the movement, ensuring that old glue, grease and stubborn dirt are thoroughly cleaned; 2. In the present invention, through the rotation design of the bearing block and the addition of the extended scrubbing plate, the first scrubbing plate, the second scrubbing plate and the extended scrubbing plate form an "L" shape.

In the present invention, when the bearing block is in the initial state, the first scrubbing plate and the second scrubbing plate are located in the second opening. At this time, the lifting block abuts against the second scrubbing plate, thereby limiting the first scrubbing plate and the second scrubbing plate in the second opening to prevent the first scrubbing plate and the second scrubbing plate from moving. At the same time, the first support rod is located in the first L-shaped groove, which means that the bearing block is directly limited so that the bearing block cannot rotate. In this way, on the one hand, the first scrubbing plate and the second scrubbing plate are limited, and on the other hand, the rotation of the bearing block is directly limited, ensuring that the first scrubbing plate and the second scrubbing plate will not rotate when the car floor is moved for cleaning.

DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-Figure 11 As shown, the present invention is a cleaning device for urban rail transit vehicles, comprising: The machine body 1 is provided with a bearing block 3, and a third opening 17 is opened therein, a first scrubbing plate 5 and a second scrubbing plate 6 are slidably installed in the bearing block 3, the top end of which passes through the top plate of the machine body 1, and a hand-held rod 4 is rotatably installed at the end, a transmission assembly 7 is provided in the bearing block 3, the first scrubbing plate 5 and the second scrubbing plate 6 are both driven by the transmission assembly 7 to move synchronously, and the movement directions of the first scrubbing plate 5 and the second scrubbing plate 6 are always opposite, and both are slidably connected with the third opening 17; An abutment rod 11 is slidably mounted on the body 1. The body 1 is provided with an adjustment assembly 13. The adjustment assembly 13 is connected to the abutment rod 11 and is used to lock the abutment rod 11. A sleeve 12 is sleeved on the abutment rod 11 and the two are rotatably connected. The sleeve 12 abuts against the edge of the seat; and The counterweight block 16 is fixedly mounted on the machine body 1 , and is symmetrically arranged with the abutment rod 11 with respect to the machine body 1 .

[0019] The working principle of the present invention is as follows: after polishing the floor of the subway car, a simple sweep is first performed, and then the detergent and water are mixed and sprinkled on the floor, especially under the seats. Then the staff holds the hand-held rod 4, moves and adjusts the position of the machine body 1, extends the first scrubbing plate 5 and the second scrubbing plate 6 into the area under the seat, and ensures that the sleeve 12 on the abutting rod 11 abuts against the edge of the seat, and then drives the first scrubbing plate 5 and the second scrubbing plate 6 to move back and forth through the transmission assembly 7, and the movement directions of the two are always opposite, and the third opening 17 provides space for the movement of the first scrubbing plate 5 and the second scrubbing plate 6, which means that when the machine body 1 stops moving, the reciprocating movement can scrub the floor of an area back and forth, without the need for manual back and forth movement of the hand-held rod 4 to drive the machine body 1 to move, that is, an automatic scrubbing process is performed, and when the machine body 1 is driven to move by the hand-held rod 4 manually, it is assumed that it is from the second scrubbing plate 6 to the first scrubbing plate 5. The first scrub plate 5 and the second scrub plate 6 move in opposite directions, and the first scrub plate 5 and the second scrub plate 6 move in opposite directions, so that the old glue, grease and stubborn dirt can be cleaned thoroughly. In addition, when the first scrub plate 5 and the second scrub plate 6 move back and forth, when the first scrub plate 5 and the second scrub plate 6 are not attached to the side wall of the subway car, it is difficult to manually control the moving direction of the machine body 1. Therefore, the design of the abutment rod 11 allows the sleeve 12 to abut against the edge of the seat, so as to provide a stable support position for the movement of the machine body 1. The abutment rod 11 is a movable design and is locked by the adjustment component 13, so that the distance between the machine body 1 and the seat can be adjusted, so that the first scrub plate 5 and the second scrub plate 6 can just clean the place where the floor and the side wall of the car are connected when they move back and forth. The counterweight of the counterweight block 16 can prevent the body 1 from shifting due to the friction of the first scrubbing plate 5 and the second scrubbing plate 6 against the ground when the body 1 is moved, resulting in the body 1 moving but the first scrubbing plate 5 and the second scrubbing plate 6 not moving synchronously, thereby ensuring the smoothness of the movement.

[0020] like Figure 3-Figure 5As shown, as a preferred embodiment of the present invention, the transmission assembly 7 includes a rotating wheel 701, a gear 702, an active rack plate 703, a driven rack plate 704, an eccentric wheel 705 and a waist-shaped groove 706. The rotating wheel 701 and the gear 702 are both rotatably installed in the supporting block 3. The rotating wheel 701 is driven to rotate by a driving source. The waist-shaped groove 706 is opened on the first scrubbing plate 5. The eccentric wheel 705 is slidably installed in the waist-shaped groove 706, and its eccentricity is fixedly installed on the rotating wheel 701. The active rack plate 703 and the driven rack plate 704 are both slidably installed in the supporting block 3, and both are fixedly connected to the first scrubbing plate 5 and the second scrubbing plate 6, respectively, and both are meshed with the gear 702.

[0021] In one case of this embodiment, the driving source may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0022] When the present embodiment is actually applied, when the driving source drives the rotating wheel 701 to rotate, it drives the eccentric wheel 705 to change its position in the waist-shaped groove 706, so that when the first scrubbing plate 5 reciprocates, the movement of the first scrubbing plate 5 drives the active rack plate 703 to move synchronously. Since the gear 702 is meshed with the active rack plate 703 and is meshed with the driven rack plate 704, the movement of the active rack plate 703 drives the gear 702 to rotate, and the gear 702 drives the driven rack plate 704 to move, but the moving direction of the driven rack plate 704 is opposite to that of the active rack plate 703. Therefore, the driven rack plate 704 drives the second scrubbing plate 6 to move, but the moving direction of the second scrubbing plate 6 is opposite to that of the first scrubbing plate 5, so that the reciprocating movement of the first scrubbing plate 5 and the second scrubbing plate 6 can enhance the scrubbing effect on the floor, thereby completely removing the stains left over from the grinding on the floor, which is beneficial to the subsequent gluing work. The sleeve 12 is rotatably mounted on the abutment rod 11. When the body 1 moves, the friction between the sleeve 12 and the edge of the seat causes the sleeve 12 to rotate, converting the sliding friction between the sleeve 12 and the edge of the seat into rotational friction, thereby reducing the resistance encountered by the body 1 during movement.

[0023] like Figure 6 As shown, as a preferred embodiment of the present invention, the adjustment assembly 13 includes a threaded segment 1301 and a nut 1302, the threaded segment 1301 is arranged on the abutment rod 11, the nut 1302 is rotatably installed on the abutment rod 11, and it is threadedly connected with the threaded segment 1301, when the nut 1302 is tightened on the threaded segment 1301, it abuts against the body 1.

[0024] In actual application of this embodiment, when the nut 1302 is tightened, it will move downward on the abutment rod 11 under the action of the threaded section 1301, and will eventually abut against the machine body 1. The movement of the abutment rod 11 is limited by the interaction force between it and the machine body 1. This operation is simple and allows workers to quickly adjust the position of the abutment rod 11.

[0025] like Figure 1-Figure 11 As shown, as a preferred embodiment of the present invention, an extended scrubbing plate 2 is fixedly mounted on the body 1, and is perpendicular to the line connecting the abutting rod 11 and the counterweight block 16, the bearing block 3 is rotatably mounted in the body 1, and its rotation axis is perpendicular to the rotation axis of the hand-held rod 4, and a locking assembly 8 is provided on the body 1, and the locking assembly 8 divides the body 1 into a first opening 14 and a second opening 15, when the bearing block 3 is in the initial state, the first scrubbing plate 5 and the second scrubbing plate 6 are located in the second opening 15, when the bearing block 3 is rotated ninety degrees, the first scrubbing plate 5 and the second scrubbing plate 6 are located in the first opening 14, and at this time the first scrubbing plate 5, the second scrubbing plate 6 and the extended scrubbing plate 2 form a whole.

[0026] In actual application of this embodiment, since the rotation axis of the bearing block 3 is perpendicular to the rotation axis of the hand-held rod 4, the hand-held rod 4 can be rotated around the axis of the bearing block 3 by holding the hand-held rod 4 with the fingers. At this time, the hand-held rod 4 can drive the bearing block 3 to rotate. In the initial state of the bearing block 3, that is, Figure 1 As shown, the first scrubbing plate 5, the second scrubbing plate 6 and the extended scrubbing plate 2 form an "L" shape. At this time, the first scrubbing plate 5 and the second scrubbing plate 6 clean the floor area under the seat of the carriage. During the movement, the extended scrubbing plate 2 can also clean other areas of the floor of the carriage. After the hand-held rod 4 is rotated, as shown in FIG. Fig.11 As shown, the first scrubbing plate 5, the second scrubbing plate 6 and the extended scrubbing plate 2 form an "I" shape and are arranged to be rotatable. That is, considering the existence of a vertical pole in the middle of the subway car, the "I" shape state can also clean under the seat, but it will be blocked by the vertical pole when moving, while the "L" shape state can ignore the obstruction of the vertical pole, and the "I" shape state can improve the cleaning efficiency in the empty car area without obstacles.

[0027] like Figure 1-Figure 9As shown in the figure, as a preferred embodiment of the present invention, the locking assembly 8 includes a lifting block 801, a first L-shaped groove 802, a second L-shaped groove 803, a first support rod 804 and a second support rod 805. The lifting block 801 is slidably installed on the body 1 and is located between the first opening 14 and the second opening 15. The first L-shaped groove 802 and the second L-shaped groove 803 are both opened on the lifting block 801 and are symmetrically arranged. The first support rod 804 and the second support rod 805 are both fixedly installed. It is installed on the supporting block 3, and both of them slide with the first L-shaped groove 802 and the second L-shaped groove 803 respectively. When the supporting block 3 is in the initial state, the lifting block 801 abuts against the second scrubbing plate 6, and the first support rod 804 is located in the first L-shaped groove 802. When the supporting block 3 rotates ninety degrees, the lifting block 801 abuts against the first scrubbing plate 5, and the second support rod 805 is located in the second L-shaped groove 803. A reset component 9 is provided on the body 1, and the reset component 9 is connected to the lifting block 801.

[0028] When the present embodiment is actually applied, the first scrubbing plate 5 and the second scrubbing plate 6 can be restricted by the setting of the lifting block 801. When the supporting block 3 is in the initial state, the first scrubbing plate 5 and the second scrubbing plate 6 are located in the second opening 15. At this time, the lifting block 801 abuts against the second scrubbing plate 6, thereby limiting the first scrubbing plate 5 and the second scrubbing plate 6 in the second opening 15 to prevent the first scrubbing plate 5 and the second scrubbing plate 6 from moving. At the same time, the first support rod 804 is located in the first L-shaped groove 802, which means that the supporting block 3 is directly limited so that the supporting block 3 cannot rotate. In this way, on the one hand, the first scrubbing plate 5 and the second scrubbing plate 6 are limited, and on the other hand, the rotation of the supporting block 3 is directly restricted, ensuring that the first scrubbing plate 5 and the second scrubbing plate 6 will not rotate when the carriage floor is moved for cleaning. Only after the locking assembly 8 rises, the first opening 14 and the second opening 15 will be connected, and the entrances and exits of the first L-shaped groove 802 and the second L-shaped groove 803 will be opened, and the supporting block 3 can rotate at this time.

[0029] like Figure 1-Figure 9 As shown, as a preferred embodiment of the present invention, the reset assembly 9 includes a bracket 901 and a first spring 902, the bracket 901 is fixedly mounted on the body 1, and is slidably connected to the lifting block 801, the top of the lifting block 801 is connected to the bracket 901 through the first spring 902, and a limiting assembly 10 is arranged in the bracket 901, and the limiting assembly 10 cooperates with the lifting block 801.

[0030] In actual application of this embodiment, since the lifting block 801 needs to rise before it can rotate the supporting block 3, and the lifting block 801 can lock the supporting block 3 after it falls, through the bracket 901 and the first spring 902, when the lifting block 801 rises, it will compress the first spring 902, and then the supporting block 3 will be rotated. After the rotation, the preload force of the first spring 902 will push the lifting block 801 to automatically fall, thereby completing the locking of the supporting block 3, and can prevent the lifting block 801 from rising due to bumps during the moving and cleaning process, thereby ensuring the stable locking effect of the supporting block 3.

[0031] like Figure 1-Figure 9 As shown, as a preferred embodiment of the present invention, the limit assembly 10 includes a cavity 1001, a limit block 1002, a second spring 1004 and an extension plate 1005. The cavity 1001 is opened in the bracket 901, and the limit block 1002 is slidably installed in the cavity 1001, and it is connected to the cavity 1001 through the second spring 1004. The preload force of the second spring 1004 makes the limit block 1002 extend in the cavity 1001. When the limit block 1002 extends, it blocks the lifting and lowering of the lifting block 801. The extension plate 1005 is fixedly installed on the top of the limit block 1002, and it is located on the outside of the bracket 901. It is used to control the contraction of the limit block 1002 in the cavity 1001. When the limit block 1002 contracts, the lifting block 801 rises and falls.

[0032] In actual application of this embodiment, the limit block 1002 is driven to retract into the cavity 1001 by moving the extension plate 1005. At this time, the limit block 1002 compresses the second spring 1004 and can move the lifting block 801 upward. When the lifting block 801 is higher than the limit block 1002, the extension plate 1005 is released, and the second spring 1004 makes the limit block 1002 extend, thereby blocking the lifting block 801 and preventing the lifting block 801 from descending. At this time, the supporting block 3 can be rotated. After the adjustment of the supporting block 3 is completed, the extension plate 1005 is pushed to make the limit block 1002 retract into the cavity 1001. Under the action of the first spring 902, the lifting block 801 will be pushed down, thereby locking the supporting block 3. Such a setting can further simplify the operation of the lifting block 801 and facilitate workers to rotate the supporting block 3.

[0033] like Figure 1-Figure 9 As shown, as a preferred embodiment of the present invention, the limit assembly 10 also includes an angle 1003, and the angle 1003 is opened on the limit block 1002. When the lifting block 801 rises, it abuts against the angle 1003, and the lifting block 801 squeezes the limit block 1002 and causes the limit block 1002 to shrink into the cavity 1001.

[0034] When this embodiment is actually used, when the lifting block 801 rises, it will abut against the bevel 1003. As it rises, it will squeeze the limit block 1002, thereby squeezing it into the cavity 1001, so that the limit block 1002 cannot block the rise of the lifting block 801. When the top of the lifting block 801 is higher than the limit block 1002, the limit block 1002 loses its obstruction and will re-extend under the elastic force of the second spring 1004, thereby blocking the lifting block 801 from descending. This can simplify the operation of the lifting block 801 when it rises. Workers can even directly hook the lifting block 801 with their feet to rise, and then after completing the rotation of the supporting block 3, they can use their feet to push the extension plate 1005 to complete the descent of the lifting block 801, thereby locking the supporting block 3. There is no need for workers to bend over to operate, which is more convenient.

[0035] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
