In order to reduce the friction between the roller and the support roller during the rotation of the mixing drum, the operator usually applies lubricant to the surface of the roller regularly. The lubrication work requires the operator to climb to the predetermined position of the mixer truck to apply the lubricant to the roller, and in order to apply it in place, the mixing drum usually needs to be rotated. This lubrication method increases the workload of the operator and poses a hidden danger to the operator's personal safety. Summary of the Invention

[0003] This invention provides a lubrication method, device, and mixer truck to solve the defects of existing technologies that require operators to climb to a predetermined position on the mixer truck to apply lubricant to the raceway, which increases the workload of operators and poses a safety hazard. The invention achieves automatic control of raceway lubrication through vibration detection, eliminating the need for operators to periodically apply grease to the raceway, reducing the workload of operators, and ensuring their safety.

[0004] This invention provides a lubrication method for a mixer truck, the mixer truck including a support roller and a raceway, wherein the outer peripheral surface of the support roller contacts the outer peripheral surface of the raceway, comprising:

[0005] Obtain the vibration parameters of the roller;

[0006] Once the vibration parameters are determined to be within the set parameter range, the lubrication device is controlled to lubricate at least one of the raceway and the support roller.

[0007] A lubrication method according to the present invention further includes:

[0008] Obtain the first lubrication time;

[0009] If the first lubrication time is determined to be greater than the second lubrication time, the vibration parameters of the roller are obtained, and the second lubrication time is the previous lubrication time plus a first preset time.

[0010] According to a lubrication method provided by the present invention, the vibration parameters include at least one of vibration frequency and vibration amplitude.

[0011] According to a lubrication method provided by the present invention, the first preset time is inversely proportional to the vibration parameter.

[0012] A lubrication method according to the present invention further includes:

[0013] Obtain the third lubrication time;

[0014] The third lubrication time is increased by a second preset time to obtain a fourth lubrication time;

[0015] The current time is determined to be equal to the fourth lubrication time, and the lubrication device is controlled to lubricate at least one of the raceway and the support roller.

[0018] If the current time is determined to be equal to the fourth lubrication time, a control signal is output.

[0019] Once the mixing drum is in operation, the lubrication device is controlled to lubricate at least one of the raceway and the support rollers according to the control signal.

[0020] According to a lubrication method provided by the present invention, before obtaining the third lubrication time, the method further includes:

[0021] If the start-up time is determined to be greater than the fifth lubrication time, the lubrication device is controlled to lubricate at least one of the raceway and the support roller, wherein the fifth lubrication time is the previous lubrication time plus the second preset time.

[0023] A liquid storage device, the liquid storage device being adapted to hold a lubricant;

[0031] The lubrication method provided by this invention is applicable to the lubrication of raceways in concrete mixer trucks. Since the rollers support the raceways, insufficient lubrication on the surfaces of the raceways and rollers in rolling contact can cause abnormal noise and vibration during roller rotation, generating specific vibration signals. Therefore, the vibration of the rollers can be detected to control the lubrication of the raceways. By detecting the vibration parameters of the rollers, the relationship between these parameters and a set parameter range is determined. When the vibration parameters are determined to be within the set parameter range, the lubrication device is controlled to lubricate at least one of the raceway surface and the surface of the rollers supporting the raceways, thereby achieving lubrication of the raceway surface and reducing friction between the raceways and rollers.

Furthermore, compared to manual lubrication based on experience, this invention provides more precise and rational lubrication control. The vibration parameters more directly reflect the friction between the raceway and the support rollers, allowing for more timely and effective control of the lubrication system.

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0046] like Figure 1 and Figure 2 As shown, this embodiment of the invention provides a lubrication method for a mixer truck. The mixer truck includes a support roller 100 and a raceway 200, with the outer peripheral surface of the support roller 100 contacting the outer peripheral surface of the raceway 200. The method includes:

[0047] 001, Obtain the vibration parameters of roller 100;

[0048] 002, Determine that the vibration parameters are within the set parameter range, and control the lubrication device to lubricate at least one of the raceway 200 and the support roller 100.

[0049] The lubrication method of this invention is applicable to the lubrication of the raceway 200 of a mixer truck. Since the support roller 100 supports the raceway 200, insufficient lubrication on the rolling contact surface between the raceway 200 and the support roller 100 will cause abnormal noise and vibration when the support roller 100 rotates, generating a specific vibration signal. Therefore, the vibration of the support roller 100 can be detected to control the lubrication of the raceway 200. By detecting the vibration parameters of the support roller 100, the relationship between the vibration parameters and a set parameter range is determined. When the vibration parameters are determined to be within the set parameter range, the lubrication device is controlled to lubricate at least one of the surfaces of the raceway 200 and the support roller 100 supporting the raceway 200, thereby achieving lubrication of the raceway 200 surface and reducing friction between the raceway 200 and the support roller 100.

[0050] This invention automatically controls the lubrication of the raceway 200 through vibration detection, eliminating the need for operators to periodically apply grease to the raceway 200, thus reducing operator workload and ensuring operator safety. Furthermore, compared to manual lubrication based on experience, the lubrication control of this invention is more precise and rational. The vibration parameters provide a more direct reflection of the friction between the raceway 200 and the support roller 100, allowing for more timely and effective control of the lubrication device on the raceway 200.

[0051] In this embodiment, the lubrication device can directly lubricate the surface of the raceway 200 or the surface of the support roller 100. Since the support roller 100 and the raceway 200 are in rolling contact, the surface of the support roller 100 carries lubricant onto the surface of the raceway 200, thus achieving lubrication. A brush can also be provided on one side of the support roller 100, and the lubrication device can place lubricant on the brush. During the rotation of the raceway 200, the brush contacts the surface of the raceway 200, thereby brushing the lubricant onto the surface of the raceway 200 to achieve lubrication. Lubricant can also be sprayed at the contact point between the raceway 200 and the support roller 100.

[0052] In this embodiment, the lubrication device performs lubrication for 5 to 6 seconds, that is, the lubrication device is controlled to lubricate at least one of the raceway 200 and the support roller 100, and the lubrication is stopped after 5 to 6 seconds.

[0053] According to one embodiment of the present invention, the lubrication method further includes:

[0054] Obtain the first lubrication time;

[0055] Determine that the first lubrication time is greater than the second lubrication time, obtain the vibration parameters of the support roller 100, and the second lubrication time is the previous lubrication time plus the first preset time.

[0056] In this embodiment, after the lubrication device completes one lubrication of the raceway 200, the current lubrication time is recorded as the first lubrication time. The relationship between the first lubrication time and the second lubrication time is determined. The second lubrication time is the time after adding a first preset time to the previous lubrication time adjacent to the current lubrication time. When the first lubrication time is greater than the second lubrication time, that is, when the current lubrication has occurred after the previous lubrication has elapsed by the first preset time, it proves that the current lubrication time has passed the time limit of the lubricant in the previous lubrication. Therefore, vibration control lubrication can continue to be detected to obtain the vibration parameters of the roller 100 and realize the control cycle. When the first lubrication time is less than or equal to the second lubrication time, that is, when the current lubrication has not occurred after the previous lubrication has elapsed by the first preset time, it proves that the current lubrication time has not yet passed the time limit of the lubricant in the previous lubrication. Therefore, vibration control lubrication can no longer be detected.

[0057] By limiting the lubrication time to a first preset time limit for lubricant failure, the timing and frequency of lubrication device activation can be controlled, maximizing the effect of each lubrication cycle, reducing energy consumption and lubricant waste, and avoiding over-lubrication.

[0058] In this embodiment, the first preset time can be 2.5 to 3.5 hours.

[0059] According to an embodiment of the present invention, the vibration parameters include at least one of vibration frequency and vibration amplitude. In this embodiment, the vibration parameters can be one or more of vibration frequency and vibration amplitude. The measured vibration frequency is the number of vibrations of the support roller 100 per unit time, and the measured vibration amplitude is the displacement of the cylinder body during each vibration of the support roller 100. Both vibration frequency and vibration amplitude can reflect the vibration status of the support roller 100. The set parameter range corresponds to a corresponding change in the measured vibration parameters; the vibration frequency corresponds to a set frequency parameter range, and the vibration amplitude corresponds to a set amplitude parameter range. When the friction between the raceway 200 and the support roller 100 increases to the point where lubrication is required, both the vibration frequency and vibration amplitude may reach their respective set parameter ranges.

[0060] In this embodiment, only the vibration frequency can be acquired, and if the vibration frequency is within the set frequency parameter range, the lubrication device can be controlled to perform lubrication. Alternatively, only the vibration amplitude can be acquired, and if the vibration amplitude is within the set amplitude parameter range, the lubrication device can be controlled to perform lubrication. Or, both the vibration frequency and vibration amplitude can be acquired, and the control method of the lubrication device can be obtained by comparing them sequentially with the set parameter range.

[0061] In this embodiment, vibration parameters can be obtained by receiving vibration frequency signals or vibration amplitude signals through vibration sensor 440, strain gauges, etc.

[0062] According to one embodiment of the present invention, the first preset time is inversely proportional to the vibration parameter. In this embodiment, the first preset time is a manually set time during which the lubricant can function in conjunction with the rotation of the raceway 200 and the support roller 100 for lubrication, i.e., the lubricant failure time. It is inversely proportional to the vibration parameter; that is, the larger the vibration parameter, the greater the frictional force generated when the raceway 200 and the support roller 100 rotate, and the shorter the time during which the lubricant can function in conjunction with the rotation of the raceway 200 and the support roller 100 for lubrication; conversely, the smaller the vibration parameter, the smaller the frictional force generated when the raceway 200 and the support roller 100 rotate, and the longer the time during which the lubricant can function in conjunction with the rotation of the raceway 200 and the support roller 100 for lubrication. By adjusting the period of vibration parameter detection in this way, the lubricant can be more rationally distributed and the timing of lubrication can be selected, resulting in more precise lubrication control and improved lubrication effect.

[0063] like Figure 3As shown, according to an embodiment of the present invention, the lubrication method further includes:

[0064] Obtain the third lubrication time;

[0065] The third lubrication time is increased by the second preset time to obtain the fourth lubrication time;

[0066] The current time is determined to be equal to the fourth lubrication time, and the lubrication device is controlled to lubricate at least one of the raceway 200 and the support roller 100.

[0067] In this embodiment, in addition to controlling the lubrication device to lubricate the raceway 200 by detecting the vibration of the support roller 100, the lubrication device can also be controlled to lubricate the raceway 200 by a timing mechanism. After the lubrication device completes the last lubrication of the raceway 200, the last lubrication time is recorded as the third lubrication time. A second preset time is added to the third lubrication time to obtain the fourth lubrication time. Then, a timing state is entered, and the relationship between the current lubrication time and the fourth lubrication time is determined. When the current time equals the fourth lubrication time, that is, the current time has reached the second preset time since the last lubrication, it proves that the lubricant from the last lubrication has reached its expiration time limit. Therefore, the lubrication device can be controlled to continue lubricating the raceway 200. When the current time is less than the fourth lubrication time, that is, the current time has not reached the second preset time since the last lubrication, it proves that the current time has not reached the expiration time limit of the lubricant from the last lubrication. Therefore, vibration detection and lubrication control can be discontinued.

[0068] By limiting the lubrication time with a second preset time limit based on the lubricant failure time limit, the timing and frequency of the lubrication device's activation can be controlled, maximizing the effect of each lubrication cycle, reducing energy consumption and lubricant waste, and avoiding over-lubrication.

[0069] In this embodiment, the second preset time can be 4.5 to 5.5 hours.

[0070] According to one embodiment of the present invention, the second preset time is inversely proportional to the vibration parameter. In this embodiment, the second preset time is a manually set time during which the lubricant can function in conjunction with the rotation of the raceway 200 and the support roller 100 for lubrication, i.e., the lubricant failure time. It is inversely proportional to the vibration parameter; that is, the larger the vibration parameter, the greater the frictional force generated when the raceway 200 and the support roller 100 rotate, and the shorter the time during which the lubricant can function in conjunction with the rotation of the raceway 200 and the support roller 100 for lubrication; conversely, the smaller the vibration parameter, the smaller the frictional force generated when the raceway 200 and the support roller 100 rotate, and the longer the time during which the lubricant can function in conjunction with the rotation of the raceway 200 and the support roller 100 for lubrication. By adjusting the period of vibration parameter detection in this way, the lubricant can be allocated more rationally and the timing of lubrication can be selected more precisely, making lubrication control more accurate and improving the lubrication effect.

[0071] According to an embodiment of the present invention, determining that the current time is equal to the fourth lubrication time and controlling the lubrication device to lubricate at least one of the raceway 200 and the support roller 100 includes:

[0072] Determine that the current time equals the fourth lubrication time, and output a control signal;

[0073] Once the mixing drum 300 is in operation, the lubrication device is controlled to lubricate at least one of the raceway 200 and the support roller 100 according to the control signal.

[0074] In this embodiment, the relationship between the current lubrication time and the fourth lubrication time is determined. When the current time equals the fourth lubrication time, a start control signal for the lubrication device is issued. Then, it is determined whether the stirring drum 300 is in operation. When the stirring drum 300 is in operation, the lubrication device can be controlled by the control signal to continue lubricating the raceway 200. When the stirring drum 300 is not in operation, vibration detection and lubrication control can be discontinued.

[0075] By limiting the lubrication time to a first preset time limit for lubricant failure, and controlling the timing and frequency of the lubrication device's activation, the system adds a judgment on whether the stirring drum 300 is in operation. This assists in controlling the timing of the lubrication device's activation, maximizing the effect of each lubrication cycle, reducing energy consumption and lubricant waste, and avoiding over-lubrication.

[0076] According to an embodiment of the present invention, the method further includes, before obtaining the third lubrication time:

[0077] If the start-up time is determined to be greater than the fifth lubrication time, the lubrication device is controlled to lubricate at least one of the raceway 200 and the support roller 100. The fifth lubrication time is the previous lubrication time plus a second preset time.

[0078] In this embodiment, before the timing mechanism enters the normal cycle control process, the raceway lubrication method also includes a lubrication control step at the initial stage of vehicle power-on. Specifically, after the vehicle starts working, the relationship between the start time and the fifth lubrication time is first determined. The fifth lubrication time is the time after the lubrication device performed the last lubrication on the raceway 200 before the last time the vehicle stopped working, plus a second preset time. When the start time is greater than the fifth lubrication time, that is, the start time is after the second preset time since the last lubrication, it proves that the lubricant of the last lubrication has reached its failure time limit, so vibration control lubrication can continue to be detected to achieve control cycle. When the start time is less than or equal to the fifth lubrication time, that is, the start time is not after the first preset time since the last lubrication, it proves that the current lubrication time has not yet reached the failure time limit of the lubricant of the last lubrication, so vibration control lubrication can no longer be detected.

[0079] In one embodiment, the lubricant flow rate of the lubrication device is proportional to the vibration parameter. The lubrication device is controlled to lubricate at least one of the raceway 200 and the support roller 100, i.e., the lubrication device sprays lubricant onto the surface of the raceway 200, the surface of the support roller 100, or the contact point between the raceway 200 and the support roller 100. The flow rate of the lubricant sprayed by the lubrication device can be changed according to the magnitude of the frictional force between the raceway 200 and the support roller 100. An increase in the vibration parameter results in a larger frictional force, thus increasing the lubricant flow rate; a decrease in the vibration parameter results in a smaller frictional force, thus decreasing the lubricant flow rate.

[0080] By limiting the lubricant failure time and controlling the timing and frequency of lubrication device activation, the flow rate of lubricant in the lubrication device is further controlled by vibration. This maximizes the effect of each lubrication cycle, reduces energy consumption and lubricant waste, and avoids over-lubrication.

[0081] In one embodiment, manual control can also be added during the timed control process. A control button can be set so that when a special supply of lubricant is required at a certain time point, the lubrication device can be activated to lubricate the raceway 200.

[0082] The lubrication device and mixer truck provided by the present invention are described below. The lubrication device and mixer truck described below can be referred to in correspondence with the lubrication method described above.

The pump body 430 is disposed on the nozzle 420. The sensor 440 is adapted to detect the vibration parameters of the support roller 100. The controller is adapted to determine that the vibration parameters are within a set parameter range and control the pump body 430 to drive the lubricant to be sprayed from the nozzle 420 to at least one of the raceway 200 and the support roller 100.

When the lubrication device lubricates the raceway 200, the pump body 430 drives the lubricant in the liquid storage device 410 to be sprayed through the nozzle 420 onto at least one of the raceway 200 and the support roller 100. This allows for periodic lubrication of the raceway 200 and also enables vibration detection to control the lubrication process, effectively avoiding the inconvenience and safety hazards to operators during raceway 200 lubrication.
