Description

Automatic car of cleaning of tunnel and ladder step

Technical Field

The invention belongs to the field of environment-friendly machinery, and particularly relates to an automatic car wiping and washing machine for tunnels and stairs.

Background

The existing railway station and subway station have wide tunnel, long ladder step and more ladder steps. Although the floor of the tunnel is cleaned by the floor mopping machine, the floor mopping machine mostly rotates by a disc and is matched with a small amount of water spraying, and the water sucking rake is arranged behind the disc to suck water. Such mopping machines have a narrow mopping area and have a non-clean floor after mopping. Because a thin layer of sewage always needs to be left on the ground, the ground is not clean after mopping, and the mopping is needed for multiple times. A long strip-shaped mop is also arranged in front of or behind the mopping machine. Although the mopping area is wide, the long-strip-shaped mop cannot be automatically cleaned, after a small amount of ground is mopped, the mop is dirty, an operator often continues mopping the ground, and when the operator cleans the mop, some ground is dirty. The ladder step mopping adopts machines such as ladder step mopping machines, but the mopping is also troublesome to clean. In most cases, the ladder steps are still manually dragged and wiped. Particularly, the underground passage and the stair step of the station have frequent times of stopping the train, and the time for mopping the ground each time is often very short, so that more cleaners are needed to mop the ground suddenly. The working efficiency is low, and the labor intensity of workers is high.

The height limiting wheel 21 is seen from the right position in fig. 1, and is used for limiting the height of the left frame part, the right frame part and the ground so that the mop can keep proper pressure to mop the ground.

Fig. 3 is a structural view of the corresponding mounting position of the mop and the inner hanging frame. In fig. 3, the upper part is provided with an inner hanging frame 29 and the lower part is provided with a mop. The inner hanging frame 29 is a rectangular frame strip. The two ends of the inner hanging frame 29 are connected with the side shafts 28. A gap is arranged in the middle of the inner hanging frame 29 and is used for enabling the clamping jaw in the drawing 1 to have a space when clamping the mop. The mop comprises a frame plate 37, a hanging block 36 and a handkerchief strip 38. The upper end of the handkerchief strip 38 is fixed under the frame plate 37. The lower end of the hanging block 36 is connected with the side edge of the middle part of the frame plate 37 into a whole. Two hooks 32 are fixed on both sides of the upper surface and the back surface of the hanging block 36. A notch 35 is arranged in the middle of the hanging block. A hanging card 33 is mounted in the slot 35. Two sides of the notch 35 are respectively provided with a clamping jaw hook groove 34. The jaw hook slot 34 is a hook-like space for the jaw tip when the jaw grips the hanger block. The inner hanging frame is provided with a fixture block 30 corresponding to the position of four hooks 32 on the hanging block. The thickness of the latch 30 is suitably smaller than the inter-hook width of the hook 32. The space for hanging the hook block in front of the hook is formed behind the two clamping blocks 30 on the upper edge of the inner hanging frame. The inner hanging frame is provided with bayonets 31 at the positions corresponding to the two hooks on the upper back of the hanging block. The width of the bayonet 31 is wider than the width of the hook. A latch 30 is formed below the bayonet 31. The rear side of the fixture block 30 is also provided with a hanging space for the hook block in front of the hook. Typically, the width of the hook and the thickness of the block in front of the hook are less than eight millimeters. A bayonet 31 is arranged below the middle gap of the inner hanging frame.

Fig. 4 is a diagram showing the condition that the hanging block of the mop in fig. 3 is hung on the inner hanging frame, and the hanging card is clamped in the bayonet of the inner hanging frame. The figure of fig. 4 is a drawing cut from the center of the notch of the inner hanging frame, and the hanging card 33 is not cut. The hanging card 33 is mounted in a notch on the hanging block with a shaft pin 2. The lower end of the hanging card is provided with a right-angle block. The front end of the right-angle block is inserted into the bayonet 31 of the inner hanging frame. A straight pressing block is arranged above the hanging card. A compression spring 39 is arranged between the left side above the pressing block and the rear wall of the notch of the hanging block. Pressing the pressing block above the hanging card. The right-angle block at the lower end of the hanging card exits from the bayonet 31 below the inner hanging frame. When the pressing block above the hanging card is loosened, the pressing block enables the right-angled block at the lower end of the hanging card to be inserted into the bayonet 31 under the pushing of the spring 39. Four hooks on the hanging block are hung on corresponding clamping blocks on the inner hanging frame.

Fig. 5 is a view showing a structure of a jaw. The hanging and the taking off of the hanging block on the inner hanging frame are completed by a clamping jaw clamping arm mechanism. Jaws 14 are mounted on chuck 13. The clamping jaw consists of a plate clamp and a jaw clamp. The middle and upper sections of the clamping jaws are of plate-shaped structures, namely two clamping jaws on each side are connected into a whole by using a plate, the plate part is a plate clamp, and the lower claw-shaped part of the plate clamp is a claw clamp. Two claw clamps are arranged below the plate clamp on each side, and the front ends of the claw clamps are provided with proper hooks. The clamping jaw clamping arm mechanism is widely applied in the prior art. A hydraulic cylinder 6 is arranged between the clamping head and the front arm frame. The chuck is internally provided with a device for controlling the integral rotation of the clamping jaws and the opening and closing of the clamping jaws.

The process of hanging the hanging block of the mop on the inner hanging frame by the clamping jaw clamping arm mechanism is as follows: 1. the jaws are opened to clamp the block from the middle of the front and back of the block in FIG. 3. The board clamp part on the clamping jaw presses the hanging card 33 in place, so that the front end of the right-angle block at the lower end of the hanging card is retracted into the back board surface of the hanging block. The hook at the front end of the clamping jaw is clamped into the corresponding clamping jaw hook groove 34 at the front and the back of the hanging block. Hooks 32 are provided on both sides of the jaws. 2. The gripper arm mechanism lifts the hanger block and moves to the upper inner hanger frame 29 in figure 3. The clamping jaw is just facing to the gap in the middle of the inner hanging frame, so that the lower end of the front hook block of each hook is higher than the corresponding clamping block 30 by a certain height according to a program. Then the clamping jaw approaches the hanging block to the inner hanging frame and is attached to the corresponding surface of the inner hanging frame. Two hooks 32 on the upper side of the hanging block are opposite to the upper part of the fixture block 30. The two hooks below the hanging block enter the bayonet 31 and are opposite to the fixture block 30 below the bayonet 31. Subsequently, the clamping jaws move the hanging block downwards for a certain distance according to the program, and then the four hooks are hung on the inner hanging frame, as shown in fig. 4. Then, the clamping jaws are loosened, moved away, the pressing block above the hanging card 33 is released, and then the front end of the right-angle block below the hanging card is clamped into the corresponding bayonet 31 of the inner hanging frame. At this time, the hanging block and the mop can not move back and forth, left and right, up and down on the inner hanging frame.

The mop is taken down from the inner hanging frame and the process is carried out reversely. The clamping jaw clamps the hanging block from the center of the inner hanging frame and presses the pressing block above the hanging block. The right-angle block at the lower end of the hanging block retreats and exits from the bayonet 31. Then, the clamping jaw moves the hanging block upwards for a set height, and each hook exits from the clamping block. The hanging block is taken down, and then the mop can be moved away by the clamping jaw.

The structure of the mop hanging block hung in the middle of the inner hanging frame 29 and the outer hanging frame 19 is the same. The space coordinate positions of the hanging frame and the outer hanging frame in each block are in the program of the automatic control system. The clamping jaws take down and hang up the hanging blocks, and the rotating angles of the rear clamping arms, the telescopic distances of the rear clamping arms and the front clamping arms, the extending lengths of piston rods of the hydraulic cylinders and the rotating angles of the clamping heads are respectively set in a program according to different space positions of the inner hanging frame and the outer hanging frame. The clamping jaw can be positioned accurately. The position sensors are arranged on the attaching surfaces of the inner hanging frame and the outer hanging frame for attaching the mop, which are not shown in the figure, and are more beneficial to the attaching of the hanging blocks of the mop on the inner hanging frame and the outer hanging frame.

Fig. 6 is a view showing the state where the inner hanging frame is attached to the rotating frame. The rotating frame comprises a front end plate 42, a rear end plate 42, a main shaft 41 and two supporting plates 44. The two supporting plates 44 are connected and fixed with the two upper sides of the two end plates 42 into a whole. The two end plates 42 are connected to a main shaft 41. Two side shaft holes and shaft sleeves are arranged on the two end plates. The side shafts 28 at two ends of the two inner hanging frames 29 are arranged in side shaft holes on the end plates side by side. One of the end plates, i.e. the front end plate in fig. 6, is provided with a main gear 40 and two side gears 43, which are engaged with each other. An intermediate gear 45 is mounted between the main gear and one of the side gears in meshing engagement with each other. The main gear 40 has a sleeve which is fitted over the main shaft 41. Two side gears are mounted and fixed on the side shaft 28. An intermediate gear 45 is pivotally mounted to the end plate. The main gear and the two side gears have the same number of teeth. The main gear is rotated ninety degrees in the forward and reverse directions, and then the middle gear 45 drives the two side gears 43, namely the inner hanging frame 29, to rotate ninety degrees in the forward and reverse directions. Two mops are arranged at two sides of the inner hanging frame of the two blocks.

Fig. 7 is a view showing an installation position during mop cleaning. The hanging blocks of the mop are hung on the inner hanging frame 29 according to the descriptions in the figures 3, 4 and 6, and two mops are symmetrically arranged on the outer side edges of the two inner hanging frames. The inner hanging frame 29 and the hanging block 36 are in a vertical state. The frame plate 37 of the mop is horizontal. This is the case when the mop plate and the handkerchief strip 38 are in position when the mop is being washed.

Fig. 8 is a view showing the installation position of the mop in dehydration. Based on the mop position of fig. 7, the main gear is rotated ninety degrees counterclockwise, which in turn rotates the right side gear ninety degrees counterclockwise. The right side gear drives the left side gear to rotate ninety degrees clockwise. Therefore, the right inner hanging frame drives the right mop to rotate ninety degrees to the right, and the left inner hanging frame drives the left mop to rotate ninety degrees to the left. The two mops are both in an upward vertical state and are respectively positioned at two sides of the main shaft 41, which is the position of the mops during dehydration.

Fig. 9 is a structural view of a driving and locking device of the main gear. A main gear 40 to which a hub 50 is coupled is mounted on a main shaft 41 of a head plate 42 of the spin stand in the wash tank. See main gear position in fig. 6. The sleeve 50 is fitted over the main shaft 41 and can rotate with the main shaft. The sleeve 50 is connected integrally with an outer dog clutch disc 51 through a wash tank shell plate 49 at one end of the wash tank. The right hand side of figure 9 mounts a motor 11 to the wash tank housing plate 49 by means of a bracket 53. The front end of the motor output shaft carries a clutch plate 51 which mates with a dog clutch plate attached to the sleeve 50, this clutch plate not being shown in cross-section. In the cleaning tank, a cassette block 47 is symmetrically fixed on both sides of the main shaft 41 between the main gear 40 and the end plate 42. A flat notch is made in the block. The slot extends up and down through the cassette block of fig. 9, and is hollowed out along with the spindle. The strength reduction of the main shaft digging-through part is compensated by the support of the upper box block and the lower box block. In the cassette block, a clutch card 46 is mounted. The lower end of the clutch block 46 is hinged on wall blocks at two sides of the lower end of the box block 47. The upper end of the clutch clamp is a clamping block, a compression spring hole is arranged in the clamping block, and a spring 39 is arranged in the spring hole. The left end of the spring 39 is abutted against the pit hole on the box block wall opposite to the left side of the clamping block. The main gear 40 has a positioning opening or a bayonet which is matched with the latch block. The block of the clutch block 46 is just blocked in the bayonet of the main gear, namely the positioning hole, under the action of the spring 39. The main gear 40 is provided with two positioning holes, and the two positioning holes are arranged on the same circumference at a distance of ninety degrees. Namely, the connecting lines from the centers of the two positioning ports to the center of the main gear are mutually vertical. A round hole is arranged in the main shaft. A push rod 48 is mounted in the circular hole. The left end of the push rod 48 is hinged with the middle part of the clutch clamp. The right end of the push rod has a certain gap with the round hole in the main shaft, and the push rod can be properly swung up and down a little. The left end and the middle part of the push rod have larger clearance with the round hole in the main shaft, and can do larger upper and lower deflection. In fig. 9, a prop 52 is mounted in the middle of the clutch disc connected with the right motor. When the clutch plate is disengaged, there is a slight clearance between the abutment 52 and the push rod 48.

The other end of the cleaning pool is connected with and provided with a servo motor, hereinafter referred to as a left motor, on the main shaft for driving the main shaft to rotate. An angle detection device is arranged between the left motor shaft and the corresponding cleaning pool shell plate. In the automatic control system, when the spindle is operated and stopped, the scale corresponding to the spindle when the mop is in the horizontal state as shown in fig. 7 is set, that is, the scale corresponding to the spindle when the mop is in the cleaning state is used as a stop point. The right side of fig. 9 is provided with a motor for driving the clutch disc, hereinafter referred to as a right motor. The right motor is also a servo motor. An angle detection device is also arranged between the back of the clutch disc on the right motor and the shell at the front end of the motor which is opposite to the back of the clutch disc on the right motor, so that after the clutch disc on the right motor is jointed with the clutch disc on the shaft sleeve, the right motor rotates only ninety degrees in positive rotation and negative rotation every time. The left motor, the clutch disc, the gear and the clutch card are arranged, and the two inner hanging frames in the cleaning pool can rotate forward and backward by ninety degrees. When cleaning, the mop is in a cleaning state as shown in fig. 7; during dehydration, the mop is brought to the dehydrated state as described in fig. 8.

The right motor drives the main gear to rotate, and the working process of driving the inner hanging frame and the mop to rotate ninety degrees is as follows: when the left motor is stopped, the control system stops the main shaft under the condition that two mops are in a horizontal state in the figure 7 according to the angle detector matched with the left motor. During the rotation of the left motor, the clutch card is always clamped in a bayonet representing the vertical state of the mop in the main gear wheel disc, and the main gear rotates along with the main shaft. After the left motor is stopped, the clamping block of the clutch clamp is still in the bayonet on the main gear wheel disc. The mop is switched between a vertical state and a horizontal state, and the working process is as follows: 1. the automatic control system is set, in the process of cleaning the mop, a clutch disc on the right motor is disconnected and powered off, and the left motor rotates forwards and backwards at an angle to be matched with a stirring and cleaning rod arranged in the cleaning pool for cleaning; when dehydration is required, the left motor stops at the set position of the main shaft, and at the moment, the clamping block of the clutch clamp is still clamped in the bayonet on the main gear wheel disc. 2. The right motor is energized and the clutch plate is engaged. In the process of engaging the clutch disc, in the process of inserting the jaw on the clutch disc on the right motor into the clutch disc on the shaft sleeve, the abutting column 52 also moves towards the left side in the figure 9 at the end of the abutting push rod 48, and the clamping block at the upper end of the push clutch clamp 46 is pushed to exit from the clamping opening on the main gear wheel disc. After the jaw of the clutch disc is inserted in place, the right motor rotates ninety degrees according to the set direction and then stops. At this time, the two inner hanging frames and the hung mop in the cleaning pool rotate ninety degrees in the respective corresponding directions to become a dehydration state, as shown in the position of fig. 8. Then, the clutch on the right motor is disengaged, and the prop 52 is retracted accordingly. The clutch block swings towards the right side in figure 9 under the action of the spring 39, and the block at the upper end of the clutch block is inserted into the other bayonet of the main gear. 3. The left motor is electrified to drive the main shaft to rotate for dehydration. 4. After the dehydration is finished, the left motor is stopped, and when the left motor needs to be cleaned again, the right motor is electrified, and according to the process, the clutch disc jaw is inserted, the support column supports the push rod to retreat, and the clutch card retreats. The right motor rotates ninety degrees in the reverse direction, namely the inner hanging frame and the mop are rotated from the dehydration state to the cleaning state. For later use, the above-described operations are repeated.

The left motor rotates a small angle, generally about ten degrees, leftwards and rightwards according to a set speed. The main shaft rotates counterclockwise for an angle, and the mop moves to the right. At this time, a motor connected with a rotating shaft of the stirring and washing device drives the stirring and washing bar to rotate a set angle towards the left side in the figure 10 according to a set speed, and the stirring and washing bar moves towards the left side to stir and wash the handkerchief strips. Otherwise, the main shaft rotates clockwise, the mop moves leftwards, the stirring and washing rod rotates anticlockwise for an angle under the driving of the motor, and the stirring and washing rod moves rightwards to stir and wash the handkerchief strip. FIG. 10 shows the case where the agitation washing bar, the crank, and the rotary shaft are mounted on the washing tub, and the case where the agitation washing device is in the mop position in the washing state. When the cleaning is finished, the left and the right stirring and cleaning bars respectively rotate towards the directions of the adjacent cleaning pool shell plates, so that the left and the right stirring and cleaning bars are close to the adjacent cleaning pool shell plates. At the moment, the stirring and washing rod leaves the position of the mop, the mop can be taken away by the clamping jaw or hung on the inner hanging frame or rotated to a dehydration state for dehydration operation, and the stirring and washing rod cannot interfere with the mop.
