The reciprocating motion of the incinerator drive device causes the grates to move alternately, pushing the domestic waste to the next level of grate, thereby achieving drying, combustion and burnout of the domestic waste.

[0003] The driving device is the core unit of the mechanical grate furnace. The incinerator needs to operate in a high-temperature, pressurized, sealed, and corrosive environment. The operating environment conditions of the equipment are extremely harsh. Once the related parts of the driving device inside the incinerator fail and the furnace has to be shut down, it will not only affect the operation of the domestic waste incineration plant, but also bring greater environmental risks.

[0004] In the transmission mechanism driven by hydraulic cylinders or pneumatic cylinders, the connection between the drive shaft and the drive arm can be keyed or connected by a locking sleeve. If the locking sleeve fails to detect failure in time, the drive shaft and the drive arm will be out of the designed motion trajectory and fixed position, causing the incinerator to fail, resulting in economic losses and environmental risks that require shutdown.

[0026] like Figure 1 , Figure 2 , Figure 3As shown, a garbage incinerator driving device of the present invention comprises a driving arm 11, a driving shaft 12, a tightening sleeve 13, and a deformation indicating card plate 14. One end of the driving arm 11 is connected to a power assembly, and the other end of the driving arm 11 is connected to an input end of the driving shaft 12 through the tightening sleeve 13. The deformation indicating card plate 14 is a long strip plate-shaped body, and the deformation indicating card plate 14 is connected between the outer end surface of the driving shaft 12 and the outer end surface of the driving arm 11. The driving arm 11 is connected to the driving shaft 12 through the tightening sleeve 13, and the driving arm 11 and the driving shaft 12 transmit torque, axial force or a composite load of torque and axial force through the pressure between the contact surfaces and the friction force generated by the accompanying friction. If the tightening sleeve 13 fails during use, relative sliding occurs between the driving arm 11 and the driving shaft 12, and the deformation indicating card plate 14 is deformed. The operator can timely discover the failure of the tightening sleeve 13 through the deformation of the deformation indicating card plate 14 and handle it in time. The invention discloses a garbage incinerator driving device, which comprises a driving arm 11, a driving shaft 12, a tightening sleeve 13 and a deformation indicating card plate 14. The deformation indicating card plate 14 is connected between the outer end surface of the driving shaft 12 and the outer end surface of the driving arm 11. Therefore, when the tightening sleeve 13 fails and the deformation indicating card plate 14 is deformed, it can be discovered in time, thereby avoiding further increase of the relative sliding angle between the driving arm and the driving shaft, causing dislocation, deformation and even damage of the connected parts on the driving shaft, resulting in the incinerator having to be shut down for treatment, thereby avoiding the expansion of losses. At the same time, the deformation indicating card plate 14 can also play a positioning role in the relative position of the driving arm and the driving shaft during installation, thereby simplifying the installation process. The invention has a simple structure, low processing cost, and convenient and quick assembly and maintenance.

[0027] Alternatively, if Figure 4 , Figure 5 As shown, the driving arm 11 includes a sleeve 111, a first connecting plate 112, and a second connecting plate 113. The first connecting plate 112 and the second connecting plate 113 are respectively connected to the two ends of the sleeve 111 in the axial direction. The first connecting plate 112 and the second connecting plate 113 are parallel to each other. The deformation indicating card plate 14 is connected between the outer end surface of the driving shaft 12 and the outer end surface of the sleeve 111. The expansion sleeve 13 is arranged in the sleeve 111. The ends of the first connecting plate 112 and the second connecting plate 113 away from the sleeve 111 are connected to the power assembly. Specifically, the first connecting plate 112, the second connecting plate 113 and the sleeve 111 are welded to each other, the inner ring of the sleeve 111 is connected to the outer ring of the expansion sleeve 13, the inner ring of the expansion sleeve 13 is connected to the driving shaft 12, the sleeve 111 bears the radial force and friction force of the expansion sleeve 13, and the sleeve 111 is made of high-strength material to ensure strength and stability.

[0028] Optionally, a first groove passing through the axis and radially penetrating the drive shaft 12 is provided on the outer end surface of the drive shaft 12, and a second groove 114 passing through a side wall of the sleeve 111 in the radial direction is provided on the outer end surface of the sleeve 111. The first groove and the second groove 114 match the deformation indicating card plate 14, and the deformation indicating card plate 14 is arranged in the first groove and the second groove 114. The deformation indicating card plate 14 is connected to the drive shaft 12 through a fastener, and the deformation indicating card plate 14 is clamped in the second groove 114. Specifically, the deformation indicating card plate 14 is connected to the drive shaft 12 through a fastening bolt 141, and a fastening gasket 142 is arranged between the fastening bolt 141 and the deformation indicating card plate 14. The second groove 114 is processed after the sleeve 111 is welded to the first connecting plate 112 and the second connecting plate 113 to ensure that the center line of the second groove 114 passes through the axis of the sleeve 12. The deformation indicating card plate 14 is disposed in the first groove and the second groove 114 , so that the deformation indicating card plate 14 is easy to install.

[0029] Optionally, a plurality of second grooves 114 are provided, the center of each second groove 114 passes through the axis of the sleeve 111, and the plurality of second grooves 114 are distributed along the circumference of the sleeve 111. A plurality of second grooves 114 are provided to meet different angle requirements when the drive arm is assembled with the drive shaft, thereby improving the versatility of the drive arm.

[0030] Optionally, a garbage incinerator drive device of the present invention further includes a locking sleeve failure warning element, which is connected to the deformation indication card plate 14. The locking sleeve failure warning element is located at a position corresponding to the area of ​​15mm-40mm between the outer diameter of the drive shaft 12 and the inner diameter of the sleeve 111. In the area of ​​about 15mm-40mm between the outer diameter of the drive shaft 12 and the inner diameter of the sleeve 111, the deformation indication card plate 14 is subjected to the greatest force, the deformation is most obvious, and the deformation signal is easy to collect. The locking sleeve failure warning element is arranged on the deformation indication card plate 14, so that a small amount of relative sliding between the drive arm and the drive shaft can be detected at the early stage of the locking sleeve failure, thereby avoiding the damage to the incinerator drive equipment caused by the large-angle relative sliding between the drive arm and the drive shaft after the locking sleeve completely fails, and reducing the operating pressure of the garbage incineration plant.

[0031] Optionally, the expansion sleeve failure warning element is a strain gauge 15, such as Figure 6As shown, it also includes an amplifier, an AD converter, and a control unit. The strain gauge 15 is connected to the amplifier, the amplifier is connected to the converter, and the converter is connected to the control unit. When the deformation indication card plate 14 is slightly deformed by torque at the initial stage of failure of the expansion sleeve 13, the strain gauge 15 is deformed, and the deformation signal of the strain gauge 15 is amplified by the amplifier. The deformation signal amplified by the amplifier is converted into a torque value by the converter and then transmitted to the control unit. The control unit is preset with a torque setting value. When the torque value is greater than the torque setting value, the control unit sends an alarm message. Specifically, strain gauges 15 are pasted on both sides of the indicator card in the gap between the inner diameter of the sleeve 111 and the outer diameter of the drive shaft 12. The strain gauges 15 and the balancing resistor together form a Wheatstone bridge. An excitation signal is applied to the Wheatstone bridge, and the positive and negative signals of the output signal are connected to an amplifier. The amplifier is a low-noise amplifier. When the deformation indicator card 14 is slightly deformed by torque at the initial stage of failure of the expansion sleeve 13, a weak voltage difference is generated between the positive and negative signals of the Wheatstone bridge, which is amplified by the amplifier, converted into a torque digital signal by an AD converter and sent to the control unit. When the torque digital signal value is greater than the torque setting value, that is, when the torque applied to the deformation indicator card 14 exceeds the set threshold, the control unit sends an alarm. After receiving the alarm information in the combustion control room of the incinerator, the operating personnel can promptly check whether the installation of the drive arm and the drive shaft has been loosened, and perform tightening and maintenance in time. Through the strain gauge 15, amplifier, AD converter and control unit, the failure of the expansion sleeve can be discovered in the early stage, which can avoid serious accidents such as dislocation of the drive shaft and damage to the incinerator driving equipment caused by the complete failure of the expansion sleeve. The operating personnel can get the alarm information in time in the combustion control room of the incinerator to ensure the timeliness of accident handling.
