Wherein, the opening and closing equipment for trash rack and inspection gate can be independently or integrally arranged according to the arrangement.

In some embodiments, the multifunctional trash remover further comprises a hydraulic grabbing beam, and the lifting mechanism is connected with the trash rack or the gate through the hydraulic grabbing beam; the hydraulic grabbing beam comprises a grabbing beam body; two groups of upper hoisting points which are arranged on the upper side of the grabbing beam body and are used for being detachably connected with a movable pulley block of a hoisting mechanism; and a group of lower hoisting points arranged on the lower side of the grabbing beam body, wherein a group of lower hoisting points correspond to the single hoisting points of the trash rack or the gate.

Because for some apertures with a large aspect ratio, the gates and the trash racks are usually provided with only one lifting point according to the specifications; however, since the dirt under the trash rack at the water inlet is uneven, the single-lifting-point trash removal rake is prone to losing balance in the trash removal and lifting processes, and therefore, the trash removal rake is usually provided with two lifting points (i.e., double lifting points). Because the quantity of the lifting points of the gate, the trash rack and the trash-cleaning scraper bucket is different, the universality of the trash-cleaning machine on the trash-cleaning scraper bucket, the trash rack and the trash-cleaning scraper bucket is reduced.

The hydraulic grabbing beam is introduced, the upper parts of the hydraulic grabbing beam are provided with two groups of upper lifting points, the lower parts of the hydraulic grabbing beam are provided with one group of lower lifting points, the upper lifting points are detachably connected with a lifting mechanism of the trash remover, and when the trash rack or the gate needs to be controlled to lift through the trash remover so as to control the opening and closing of the trash rack or the gate, the hydraulic grabbing beam can be switched to realize the lifting and lowering of the trash rack or the gate; when dirt in front of the trash rack is cleaned by the trash cleaning machine control trash cleaning scraper bucket, the trash cleaning machine is directly connected with the trash cleaning scraper bucket, and at the moment, the hydraulic grab beam is connected to the trash rack or the gate. Therefore, the universality of the trash remover is improved.

In some embodiments, the multifunctional trash remover further comprises a stable guiding device which is arranged on the grabbing beam body and used for preventing the grabbing beam body from shaking in the lifting motion process. Therefore, the lifting stability of the trash rack and the gate which are connected to the hydraulic grabbing beam in a driving mode of the trash remover can be improved.

In some embodiments, the multifunctional trash remover further comprises two sets of guide positioning sleeves arranged on the grabbing beam body, and one set of guide positioning sleeve is arranged on each of two sides of the lower lifting point and corresponds to the guide rods arranged on the gate or the trash rack. Therefore, when the grabbing beam body is close to the gate or the trash rack, the hydraulic grabbing beam can be automatically aligned with the gate or the trash rack through the guiding effect of the guide rod and the guide positioning sleeve, so that the hydraulic pin penetrating device is coaxial with a lifting lug on a lifting point of the gate or the trash rack, and the grabbing beam and the gate or the trash rack are ensured to automatically penetrate and separate from each other.

In some embodiments, the multi-functional trash remover further comprises an adaptor detachably connected to the lower lifting point for detachable connection with at least one of the trash rack and the gate. Because the single hoisting point of trash rack and gate probably not all with the lower part hoisting point adaptation of hydraulic pressure grab beam, through introducing the adaptor, can set the lower part hoisting point to the single hoisting point adaptation with the trash rack to set the adaptor to can dismantle with another single hoisting point and be connected, under the condition that does not change the original structure of trash rack and gate from this, guarantee the commonality of hydraulic pressure grab beam and trash rack and gate.

Fig. 1 to 8 schematically show a multi-functional trash remover according to an embodiment of the present invention.

As shown in fig. 1 to 5, the multifunctional trash remover comprises a travelling mechanism 32, a lifting mechanism 31 and a trash removing rake 38; wherein, the running gear 32 is arranged on the gate pier 100; the hoisting mechanism 31 is arranged on the travelling mechanism 32; the traveling mechanism 32 is arranged to drive the hoisting mechanism 31 to reciprocate along the arrangement direction of the door slot 1021, the grid slot 1022 and the scraper bucket 1023; the lifting mechanism 31 is arranged to be detachably connected with the trash cleaning rake 38, the trash rack 104 and the gate 105, and the lifting mechanism 31 is also arranged to drive the trash cleaning rake 38, the trash rack 104 or the gate 105 connected with the lifting mechanism to move up and down and drive at least two of the trash cleaning rake 38, the trash rack 104 and the gate 105 to move at different speeds.

In some embodiments, as shown in fig. 3, the hoisting mechanism 31 is further configured to move at least two of the trash rake 38, the trash rack 104, and the gate 105 at different speeds, implemented to include: a function selection switch 300 and a control system 200 are arranged; the control system 200 is configured to start the trash removal switch according to the function selection switch 300, and control the driving device of the lifting mechanism 31 to drive the trash removal rake 38 to move at a high speed; the control system 200 is further configured to activate the on-off switch according to the function selection switch 300, and control the driving device of the hoisting mechanism 31 to drive the trash rack 104 or the gate 105 to move at a low speed. Therefore, the present invention can adjust the speed of the driving device of the lifting mechanism 31 driving the dirt-removing rake 38, the trash rack 104 and the gate 105 to do lifting movement by the way that the control system 200 controls the driving speed of the driving device of the lifting mechanism 31.

Illustratively, as shown in fig. 4, the first embodiment in which the control system 200 is configured to activate the purge switch according to the function selection switch 300 and control the driving device of the lifting mechanism 31 to drive the purge rake 38 to move at a high speed is: the control system 200 of the hoisting mechanism 31 is provided with a hoisting frequency converter 316, the driving device of the hoisting mechanism 31 is a first motor 312, the control system 200 is configured to start the decontamination switch according to the function selection switch 300, a high-frequency instruction is sent to the hoisting frequency converter 316, and the hoisting frequency converter 316 controls the first motor 312 to drive the decontamination rake 38 to move at a high speed according to the high-frequency instruction. Preferably, the first motor 312 is a variable frequency motor.

Illustratively, with continued reference to fig. 4, the first embodiment in which the control system 200 is configured to activate the on/off switch according to the function selection switch 300 and control the driving device of the hoisting mechanism 31 to drive the trash rack 104 or the gate 105 to move at a low speed is: the lifting mechanism 31 is provided with a lifting frequency converter 316, the driving device of the lifting mechanism 31 is a first motor 312, the control system 200 is configured to start the on-off switch according to the function selection switch 300, send a low-frequency instruction to the lifting frequency converter 316, and the lifting frequency converter 316 controls the first motor 312 to drive the trash rack 104 or the gate 105 to move at a low speed according to the low-frequency instruction. Preferably, the first motor 312 is a variable frequency motor.

As shown in fig. 5, the second embodiment in which the control system 200 is configured to activate the purge switch according to the function selection switch 300 and control the driving device of the lifting mechanism 31 to drive the purge rake 38 to move at a high speed is: the drive equipment of the hoisting mechanism 31 is a two-speed motor 317, and the control system 200 is configured to activate the trash removal switch according to the function selection switch 300, and control the two-speed motor 317 to drive the trash removal rake 38 to move at a high speed.

With continued reference to fig. 5, the second embodiment of the control system 200 configured to activate the on/off switch according to the function selection switch 300 and control the driving device of the hoisting mechanism 31 to drive the trash rack 104 or the gate 105 to move at a low speed is: the driving device of the hoisting mechanism 31 is a two-speed motor 317, and the control system 200 is configured to start the on-off switch according to the function selection switch 300, and control the two-speed motor 317 to drive the trash rack 104 or the gate 105 to move at a low speed.

A third embodiment of the control system 200 configured to activate the trash removal switch according to the function selection switch 300 and control the driving device of the lifting mechanism 31 to drive the trash removal rake 38 to move at a high speed is as follows: the drive for the hoist 31 is a first motor 312 and the control system 200 is arranged to activate the purge switch in response to the function selector switch 300 to control the reduction of a resistor 44 (not shown) connected in the circuit of the first motor 312.

The third embodiment of the control system 200, which is configured to start the on-off switch according to the function selection switch 300 and control the driving device of the hoisting mechanism 31 to drive the trash rack 104 or the gate 105 to move at a low speed, is as follows: the drive for the hoist 31 is a first motor 312 and the control system 200 is arranged to activate the on/off switch in response to the function selector switch 300 to control the increase of the resistance 44 (not shown) connected to the circuit of the first motor 312.

Because the sum of the weight of the dirt removing rake 38 and the weight of the dirt is far less than the weight of any one of the gate 105 and the trash rack 104, the lifting mechanism 31 can be set to drive the dirt removing rake 38 to move at a speed higher than the speed for driving the gate 105 or the trash rack 104 to move, so that the power consumed when the lifting mechanism 31 drives the dirt removing rake 38, the gate 105 and the trash rack 104 to move is approximately equal, and the purposes of improving the dirt removing efficiency and saving energy are achieved. Especially when the control speed adopts a scheme including the first motor 312 and the lifting frequency converter 316, the control system 200 may adopt a conventional PLC, for example, because the transmission ratio on the transmission chain is a fixed value in the same lifting mechanism 31, the speed of the lifting mechanism 31 driving the trash rack 104, the gate 105 or the trash rack 38 to do lifting motion is proportional to the rotation speed of the first motor 312, and the rotation speed formula of the first motor 312 is:

in the formula:

p is the number of pole pairs of the stator of the motor; f1 is the power frequency; s is the slip.

The boost converter 316 may convert a fixed frequency 50Hz (or 60Hz) power supply to a variable frequency power supply of 0Hz to 120Hz (or higher) via rectification and an inverter. When the first motor 312 is a variable frequency motor, corresponding to a variable frequency motor of the same model, the number p of pole pairs of a stator of the motor and the slip ratio s are not changed, but the frequency f1 of a driving power supply is changed, so that the speed of the lifting mechanism 31 driving the dirt removing rake 38, the gate 105 and the trash rack 104 to move can be adjusted according to the frequency of the driving power supply for adjusting the first motor 312, that is, the speed of the lifting mechanism 31 driving the dirt removing rake 38, the gate 105 and the trash rack 104 to move is changed. Taking 380V of power voltage connected to the first motor 312 and 50Hz as an example, when the lifting mechanism 31 drives the gate 105 or the trash rack 104 to perform lifting movement at a speed of 2m/min, the driving frequency of the first motor 312 is 50Hz of the rated frequency of the first motor 312; when the frequency of a power supply with the frequency of 50Hz is adjusted to 80Hz through a frequency converter, the speed of the first motor 312 for driving the cleaning rake 38 to move up and down is 3.2m/min according to a formula, and the requirement of the specification that the speed is 3-10 m/min during cleaning is met.

When the inverter motor as the first motor 312 is operated within 50Hz of the rated frequency, the motor has a constant torque characteristic in which the output torque of the motor is constant, the output power increases with the increase of the rotation speed, and reaches the rated power at 50 Hz. When the inverter motor as the first motor 312 is operated at over 50Hz, it has an operation characteristic of constant power, that is, the output power is constant, and the output torque is inversely proportional to the rotation speed. According to the working characteristic of the variable frequency motor, the high-speed requirements of large opening and closing force (corresponding to the requirement that the large output torque of the first motor 312 is lower than the rated rotating speed) for opening and closing the gate 105 or the trash rack 104 (driving the gate 105 or the trash rack 104 to do lifting motion) and small opening and closing force (corresponding to the requirement that the small output torque of the first motor 312 is higher than the rotating speed) during trash cleaning can be realized.

Meanwhile, the variable frequency motor and the control thereof are adopted, so that the operation of the trash remover is more green and energy-saving.

Preferably, the variable frequency motor as the first motor 312 adopts a variable frequency technology or an over-frequency technology, so as to achieve the purpose of further saving energy.

In the preferred embodiment, the purge switch and the on-off switch of the function selecting switch 300 are interlocked with each other. So as to ensure that only one operation can be carried out in one time period and ensure the stability of each operation.

In a preferred embodiment, as shown in fig. 1, 2 and 6 to 8, the multi-functional trash remover further comprises a hydraulic grab beam 20.

As shown in fig. 6, the hydraulic grab beam 20 includes a grab beam body 21; an upper suspension point 211 provided on the upper side of the grab beam body 21; and a lower hoisting point 212 provided on the lower side of the grab beam body 21; wherein, two groups of upper hoisting points 211 are arranged and are used for being detachably connected with a movable pulley block 311 of a lifting mechanism 31 of the trash remover; the lower lifting points 212 are provided in a group, and a group of the lower lifting points 212 correspond to the single lifting points 1041 of the trash rack 104 or the gate 105.

When the hydraulic grab beam 20 is used, the upper lifting point 211 of the hydraulic grab beam 20 is detachably connected with the movable pulley block 311 of the lifting mechanism 31 of the trash remover, and the lower lifting point 212 of the hydraulic grab beam 20 is detachably connected with the trash rack 104 or the gate 105 (as shown in fig. 1 and 2), wherein the trash remover is arranged on the bent frame 101 of the gate pier 100, the travelling mechanism 32 of the trash remover is arranged on the bent frame 101, and the lifting mechanism 31 of the trash remover is arranged on the travelling mechanism 32. Due to the introduction of the hydraulic grab beam 20 which is provided with two groups of upper lifting points 211 at the upper part and one group of lower lifting points 212 at the lower part and is detachably connected with the movable pulley block 311 of the lifting mechanism 31 of the trash remover and the trash rack 104 or the gate 105, when the lifting of the trash rack 104 or the gate 105 needs to be controlled by the trash remover to control the opening and closing of the trash rack 104 or the gate 105, the switching of the hydraulic grab beam 20 can be realized, namely, the trash remover can be connected with the trash rack 104 through the hydraulic grab beam 20 (as shown in fig. 2) or connected with the gate 105 through the hydraulic grab beam 20 (as shown in fig. 1); when the trash cleaning rake 38 is required to be controlled by the trash cleaning machine to clean up the trash on the trash rack 104, the gate 105 can be locked on the gate pier 100 through the locking beam 106, then the trash cleaning machine passing walking mechanism 32 is moved to the position corresponding to the trash cleaning rake 38, the movable pulley block 311 of the lifting mechanism 31 of the trash cleaning machine is directly connected with the double lifting points 381 of the trash cleaning rake 38, and at the moment, the hydraulic grab beam 20 is connected to the trash rack 104 or the gate 105. Therefore, the universality of the trash remover is improved.

In a preferred embodiment, as shown in fig. 6 and 7, the hydraulic grab beam 20 further includes a smooth guide 24 provided on the grab beam body 21, and the smooth guide 24 is used to prevent the grab beam body 21 from shaking during the lifting movement.

Illustratively, gate channels 1021 and grid channels 1022 are provided on the gate pier 100 to provide vertical guidance for the gate 105 and the trash rack 104, respectively. So as to prevent the grabbing beam body 21 from shaking during the lifting movement through the first roller 241 abutting against the vertical guide groove 102; moreover, as the first roller 241 is pivotally connected to the grabbing beam body 21, the resistance of the first roller 241 to the movement of the vertical guide groove 102 can be reduced, and the lifting movement of the grabbing beam body 21 can be kept smooth while the lifting stability of the grabbing beam body 21 is ensured. Preferably, the first roller 241 is provided at least one of the upper and lower portions of the grab beam body 21. When the upper and lower portions of the grab beam body 21 are provided with the first rollers 241, the shaking of the grab beam body 21 when it is lifted and lowered can be further reduced. In general, in order to provide better guidance for the gates 105 and the trash rack 104, the gate pier 100 is provided with vertical guide grooves 102 at positions corresponding to both sides of the gates 105 and the trash rack 104, and in this case, it is preferable that the first rollers 241 are provided at both ends of the grab beam body 21.

Therefore, the second roller 242 can limit the grabbing beam body 21 to shake during the lifting movement, so that the stability of the grabbing beam body 21 during the lifting movement is ensured; moreover, since the second roller 242 is pivotally connected to the grab beam body 21, the resistance of the second roller 242 to the movement of the vertical guide groove 102 or the gate pier 100 can be reduced, and the lifting movement of the grab beam body 21 can be kept smooth while the stability of the lifting of the grab beam body 21 is ensured.

Therefore, the shaking of the grabbing beam body 21 in two directions can be limited through the first roller 241 and the second roller 242, and therefore the stability of the grabbing beam body 21 in the lifting motion is further guaranteed.

Specifically, the guide rods 1051 are connected to the top surface of the trash rack 104 or the gate 105 through the connection plate 1052. Therefore, when the grabbing beam body 21 approaches the gate 105 or the trash rack 104, the grabbing beam body 21 can be automatically aligned with the gate 105 or the trash rack 104 through the guiding action of the guide rod 1051 and the guide positioning sleeve 25, so that the hydraulic pin penetrating device 23 is ensured to be coaxial with a lifting lug on a lifting point of the gate 105 or the trash rack 104, and the grabbing beam body 21 is ensured to be automatically penetrated and detached from the gate 105 or the trash rack 104.

In a preferred embodiment, as shown in fig. 6 and 8, the hydraulic grab beam 20 further includes a lift sensor 22 provided on the grab beam body 21, the lift sensor 22 being used to detect the lift position of the grab beam body 21. Thus, the operator can know whether the grab beam body 21 moves to a position corresponding to the trash rack 104 or the gate 105 through the elevation sensor 22 to grasp a time for connecting the hydraulic grab beam 20 to the trash rack 104 or the gate 105. Illustratively, lift sensor 22 may be implemented as a travel switch or proximity switch.

In a preferred embodiment, as shown in FIG. 8, the lower suspension point 212 is a locking hole 2121; and the hydraulic grabbing beam 20 further comprises a hydraulic pin penetrating device 23 arranged on the grabbing beam body 21 and a pin penetrating piston rod 231 arranged on the hydraulic pin penetrating device 23, the hydraulic pin penetrating device 23 is arranged to drive the pin penetrating piston rod 231 to be inserted into the locking hole 2121 and the single lifting point 1041, and the hydraulic pin penetrating device 23 is further arranged to drive the pin penetrating piston rod 231 to be extracted from the locking hole 2121 and the single lifting point 1041. While the lower suspension point 212 is configured to lock the hole 2121, typically the single suspension point 1041 is also implemented as a hole configuration. At this time, when the hydraulic grab beam 20 moves to a position where the locking hole 2121 corresponds to the single lifting point 1041 under the driving of the trash remover, the pin-penetrating piston rod 231 can be driven to be inserted into the locking hole 2121 and the single lifting point 1041 by the hydraulic pin-penetrating device 23 to realize the connection of the hydraulic grab beam 20 with the trash rack 104 or the gate 105 (as shown in fig. 1 and 2); when the hydraulic grab beam 20 needs to be transferred between the trash rack 104 and the gate 105, that is, the hydraulic grab beam 20 is detached from one of the trash rack 104 and the gate 105 and connected with the other, the insertion and extraction of the penetrating pin piston rod 231 in the locking hole 2121 can be driven by the hydraulic penetrating pin device 23 to realize the automatic connection and the automatic disconnection of the hydraulic grab beam 20 with the trash rack 104 and the gate 105.

Fig. 9 to 14 schematically show a multi-function trash remover according to another embodiment of the present invention, which can be further modified as described below on the basis of the previous embodiment.

As shown in fig. 9, the trash remover with the precise alignment mechanism comprises a travelling mechanism 32, a lifting mechanism 31, a limit switch 41, a trigger unit 42 and a control system 200; wherein, the running gear 32 is arranged on the gate pier 100; the hoisting mechanism 31 and the limit switch 41 are arranged on the travelling mechanism 32; the trigger unit 42 is arranged on the gate pier 100; the traveling mechanism 32 is configured to drive the hoisting mechanism 31 to move along the arrangement direction of at least one of the gate chute 1021 and the gate chute 1022 and the gate chute 1023 on the gate pier 100 (i.e., along the gate chute 1023 and the gate chute 1022 on the gate pier 100, along the gate chute 1021 and the gate chute 1023 on the gate pier 100, or along the gate chute 1023, the gate chute 1022 and the gate chute 1021 on the gate pier 100); the trigger units 42 are at least provided in two groups, and at least two groups of trigger units 42 are respectively provided at positions corresponding to at least one of the bucket grooves 1023, the grid grooves 1022 and the door grooves 1021 (that is, the bucket grooves 1023 and the grid grooves 1022, the bucket grooves 1023 and the door grooves 1021, or the bucket grooves 1023, the grid grooves 1022 and the door grooves 1021); the control system 200 is configured to control the traveling mechanism 32 to drive the hoisting mechanism 31 to perform deceleration movement when the limit switch 41 detects the trigger unit 42.

As a first embodiment of the control system 200 controlling the traveling mechanism 32 to drive the hoisting mechanism 31 to perform the deceleration movement, the control system 200 controls the traveling mechanism 32 to drive the hoisting mechanism 31 to perform the deceleration movement by increasing the resistance value of the resistor 44 connected to the circuit of the traveling mechanism 32. Thus, when the decelerating resistor 44 is connected to the electric circuit of the traveling mechanism 32, the electric current in the electric circuit of the traveling mechanism 32 can be reduced, and the traveling mechanism 32 can be decelerated. Preferably, the resistor 44 is a variable resistor. This allows the resistance value of the resistor 44 connected to the electric circuit of the traveling mechanism 32 to be adjusted more smoothly.

Fig. 9, 10 and 12 show one embodiment of the running gear 32 by way of example, and the running gear 32 includes a running rail 322 provided on the gate pier 100; a traveling wheel 321 rotatably fitted on the traveling rail 322; a frame 35 pivotally connected to the road wheel 321 via a rotation shaft thereof; and a traveling motor 37 provided on the frame 35; wherein the hoisting mechanism 31 is arranged on the frame 35. Therefore, the walking wheels 321 can drive the frame 35 and the hoisting mechanism 31 arranged on the frame 35 to move along the walking rails 322 by driving the walking wheels 321 to rotate through the walking motors 37, and the walking direction of the walking wheels 321 along the walking rails 322 can be controlled by controlling the rotation direction of the walking motors 37. The control system 200 can control the walking motor 37 to perform deceleration movement until stopping movement according to the received signal that the limit switch 41 detects the trigger unit 42; can learn through the experiment that control system 200 control walking motor 37 is started to do the distance that running gear 32 walked during to its motion that stops the action of driven road wheel 321 when doing deceleration motion, also can learn through the experiment that running gear 32 is the distance that the deceleration motion walked, thereby can set up the position of trigger unit 42 accurately, can stop the corresponding position in door slot 1021, bars groove 1022 or rake fill groove 1023 accurately with the hoisting mechanism 31 of guaranteeing running gear 32 drive under control system 200's control, thereby obtain and can be general in the multi-functional trash cleaning machine of trash cleaning and opening and close trash rack 104 and/or gate 105 high-efficiently. Illustratively, the walking motor 37 is a wound-rotor motor, and the controlling system 200 may control the walking motor 37 to perform the deceleration movement according to the received signal of the trigger unit 42 detected by the limit switch 41, and may be implemented as follows: the control system 200 increases the resistance of the resistor 44 connected to the circuit of the wound-rotor motor according to the signal received from the trigger unit 42 detected by the limit switch 41, so as to reduce the current in the circuit of the wound-rotor motor, thereby achieving the purpose of slowing down the rotation speed of the wound-rotor motor.

Therefore, when the control system 200 controls the limit switch 41 to detect the trigger unit 42, a control signal is sent to the traveling mechanism 32, the control traveling mechanism 32 starts to perform deceleration movement until stopping movement, the distance from the control system 200 to the stop movement of the control traveling mechanism 32 when the control traveling mechanism 32 starts to perform deceleration movement can be known through experiments, that is, the distance from the traveling mechanism 32 to perform deceleration movement can be known through experiments, so that the position of the trigger unit 42 can be accurately set, the lifting mechanism 31 driven by the traveling mechanism 32 can be accurately stopped at the corresponding position in the door slot 1021, the gate slot 1022 or the rake bucket slot 1023 under the control of the control system 200, and the trash remover which can be efficiently and commonly used for cleaning, opening and closing at least two functions of the trash rack 104 and the gate 105 is obtained.

As a second embodiment of the control system 200 controlling the traveling mechanism 32 to drive the hoisting mechanism 31 to perform the deceleration movement, as shown in fig. 13, a further improvement is obtained on the basis of the first embodiment, specifically, the trash remover with the accurate alignment mechanism further includes a second brake 43; the trigger unit 42 comprises a deceleration trigger 421 and a stop trigger 422; the control system 200 is arranged to increase the resistance of the resistor 44 connected into the electric circuit of the running gear 32 to slow down the movement speed of the running gear 32 when the limit switch 42 detects the deceleration triggering device 421; when the limit switch 41 detects the stop trigger 422, the second brake 43 is controlled to brake the traveling mechanism 32. Therefore, when the hoisting mechanism 31 driven by the traveling mechanism 32 approaches the target position (the door slot 1021, the grid slot 1022 or the rake slot 1023), the limit switch 42 detects the deceleration trigger 421, and can control the traveling mechanism 32 to perform deceleration movement through the control system 200; when the hoisting mechanism 31 moves to the target position quickly, the limit switch detects the stopping trigger 422, the control system 200 can control the second brake 43 to brake the travelling mechanism 32, and the speed of the travelling mechanism 32 is lower when the second brake 43 brakes the travelling mechanism 32, so that the sliding distance of the travelling mechanism 32 after being braked by the second brake 43 can be reduced, and the hoisting mechanism 31 can be ensured to be stopped at the target position accurately and not to shake greatly.

Fig. 9 to 11 exemplarily show one embodiment of the trigger unit 42, as shown in the figure, each trigger unit 42 includes a group of deceleration trigger devices 421 and a group of parking trigger devices 422, and all the deceleration trigger devices 421 are located at the first side position of the same group of parking trigger devices 422, the deceleration trigger devices 421 and the parking trigger devices 422 are arranged according to the direction in which the travelling mechanism 32 drives the hoisting mechanism 31 to move, that is, the deceleration trigger devices 421 and the parking trigger devices 422 are arranged on the gate pier 100 along the x direction. Therefore, when the travelling mechanism 32 drives the hoisting mechanism 31 to move from the first side of the stop trigger device 422 to the opposite side thereof, the limit switch 41 can detect the deceleration trigger device 421 first, so that the travelling mechanism 32 performs deceleration movement first; then, when the limit switch 41 detects the parking trigger 422, the traveling motor 37 is de-energized, and the traveling mechanism 32 is braked by the second brake 43.

In another embodiment of the triggering unit 42, the triggering unit 42 includes two sets of deceleration triggering devices 421 and one set of stopping triggering devices 422, the deceleration triggering devices 421 and the stopping triggering devices 422 are arranged according to the direction in which the traveling mechanism 32 drives the hoisting mechanism 31 to move, and the two sets of deceleration triggering devices 421 in each set of triggering unit 42 are respectively located on two opposite sides (not shown in the figure) of the stopping triggering devices 422 in the set of triggering unit 42. Therefore, no matter which side of the lifting mechanism 31, provided with the speed reduction trigger device 421, moves to the opposite side of the stop trigger device 422 under the driving of the travelling mechanism 32, the limit switch 41 can detect the speed reduction trigger device 421 firstly and then detect the stop trigger device 422, so that the travelling mechanism 32 firstly performs speed reduction movement and then stops moving due to the fact that the travelling motor 37 loses power and is braked by the second brake 43.

Fig. 11 and 13 exemplarily show one embodiment of the deceleration trigger 421 and the parking trigger 422, and as shown in the drawings, the deceleration trigger 421 and the parking trigger 422 each include a base 4211 provided on the gate pier 100 and a shift lever 4212 provided on the base 4211; the shift lever 4212 extends in a horizontal plane toward a side where the limit switch 41 is located along a movement direction perpendicular to the traveling mechanism 32. Therefore, when the limit switch 41 arranged on the traveling mechanism 32 moves to be close to the shift lever 4212, the limit switch 41 detects the shift lever 4212, and when the control system 200 receives that the limit switch 41 detects the shift lever 4212 for the first time, the control system 200 controls the traveling mechanism 32 to perform deceleration movement; when the control system 200 receives the second detection of the shift lever 4212 by the limit switch 41, the control system 200 controls the traveling motor 37 to lose power and controls the second brake 43 to brake the traveling mechanism 32.

Preferably, with continued reference to fig. 9-11 and 13, when the trigger unit 42 includes a deceleration trigger 421 and a park trigger 422; the traveling mechanism 32 includes a traveling rail 322 provided on the gate pier 100; a traveling wheel 321 rotatably fitted on the traveling rail 322; a frame 35 pivotally connected to the traveling wheels 321 via their rotation shafts and connected to the hoisting mechanism 31; and a traveling motor 37 provided on the frame 35. The control system 200 is configured such that, when the limit switch 41 detects the deceleration triggering means 421, increasing the resistance value of the resistor 44 connected to the electric circuit of the traveling mechanism 32 is implemented to include: the control system 200 is arranged to increase the resistance of the resistor 44 connected into the circuit connected to the travel motor 37 when the limit switch 41 detects the deceleration triggering means 421. When the traveling motor 37 is a winding motor, specifically, the control system 200 may control the relay or the thyristor to connect the deceleration resistor 44 with the winding motor according to the signal received from the deceleration trigger 421 detected by the limit switch 41. The control system 200 is configured to control the second brake 43 to brake the traveling mechanism 32 when the limit switch 41 detects the parking trigger 422, and the control system is configured to include: the control system 200 is configured to control the traveling motor 37 to lose power and control the second brake 43 to brake the traveling motor 37 when the limit switch 41 detects the stop trigger 422.

As a third embodiment in which the control system 200 controls the traveling mechanism 32 to drive the hoisting mechanism 31 to perform a deceleration motion, as shown in fig. 14, in some embodiments, the precise alignment mechanism for a hoist further includes a traveling frequency converter 45, and the traveling frequency converter 45 and the hoisting frequency converter 316 may be implemented by one frequency converter, or by two frequency converters respectively; the control system 200 is configured to control the traveling frequency converter 45 to reduce the frequency and feed the reduced frequency back to the circuit of the traveling mechanism 32 when the limit switch 41 detects the deceleration trigger 421; when the limit switch 41 detects the stop trigger 422, the travel frequency converter 45 is controlled to feed back the frequency of 0Hz to the circuit of the travel mechanism 32. Therefore, when the limit switch 41 detects the deceleration trigger 421, the circuit of the traveling mechanism 32 can make the traveling mechanism 32 perform deceleration movement according to the received reduced frequency; when limit switch 41 detects stall trigger 422, circuitry of travel mechanism 32 may stop travel mechanism 32 from moving based on the received 0Hz frequency. By adopting the method, the movement speed of the travelling mechanism 32 can be controlled and the time when the travelling mechanism 32 starts to move and the time when the travelling mechanism 32 stops moving can be controlled only by controlling the frequency fed back to the circuit of the travelling mechanism 32 by the travelling frequency converter 45, so that the implementation means is simpler and more convenient. In a specific implementation manner, the circuit for feeding back the frequency to the traveling mechanism 32 by the traveling frequency converter 45 is specifically implemented as: the frequency of the traveling frequency converter 45 is fed back to a circuit connected to a driving device of the traveling mechanism 32, the driving device is generally the traveling motor 37, and a frequency conversion motor can be used as an example. Therefore, the purposes of decelerating the traveling mechanism 32 and stopping the movement of the traveling mechanism 32 can be achieved by slowing down the driving speed of the driving device such as the traveling motor 37 or stopping the driving of the traveling motor 37. Preferably, the implementation manner of the trigger unit 42 in this embodiment may refer to the trigger unit 42 in the previous embodiment, and is not described herein again.

Thus, when the limit switch 41 detects the trigger unit 42, the travel motor 37 can be controlled to perform a deceleration motion by the control system 200. When the trigger unit 42 of the hoist comprises the deceleration trigger device 421 and the stop trigger device 422, the control system 200 can control the motor of the walking machine to perform deceleration movement when the limit switch 41 detects the deceleration trigger device 421; when the limit switch 41 detects the parking trigger 422, the control system 200 controls the traveling motor 37 to stop driving the traveling wheel 321, specifically, the traveling motor 37 can be controlled to stop driving by controlling the traveling motor 37 to be disconnected from the power supply. When the hoist further comprises the traveling frequency converter 45, when the limit switch 41 detects the speed reduction trigger 421, the control system 200 controls the traveling frequency converter 45 to reduce the frequency and feed the reduced frequency back to the motor of the traveling machine, so that the traveling motor 37 performs speed reduction movement; when the limit switch 41 detects the parking trigger 422, the control system 200 can control the traveling frequency converter 45 to feed back the frequency of 0Hz to the traveling motor 37, so that the traveling motor 37 stops driving the traveling wheel 321.

In the invention, the hoisting mechanism 31 is a mechanism used for driving the trash rack 104 or the gate 105 to do lifting movement in the existing hoist, and generally, the hoisting mechanism 31 is connected with the trash rack 104 or the gate 105 through the hydraulic grabbing beam 20; the limit switch 41 is also a travel switch, and the limit switch 41 commonly used in the prior art is adopted; the control system 200 comprises a PLC commonly used in the prior art; the walking frequency converter 45 is a walking frequency converter 45 commonly used in the prior art; the second brake 43 may be a second brake 43 commonly used in the prior art, as long as the second brake can stop the traveling motor 37 from driving the traveling wheels 321 to travel along the traveling rail 322.
