Description

Technical Field

[0001] The invention relates to the technical field of butter filling systems, and in particular to a full-automatic butter multi-point pump filling system. Background Art

[0002] For the full-section slightly weathered granite long-distance shield tunneling project, the project adopts a continuous belt plus a vertical lifting belt transfer system to transfer shield slag according to the actual situation. The vertical transfer belt needs to lift the slag vertically by 40 meters during the vertical lifting process, which causes the equipment-related rotating bearings to bear a large load and requires frequent grease lubrication. The operators have to add grease with high labor intensity and high frequency. The equipment cannot be stopped for filling during the filling process, resulting in high-intensity and heavy work for the operators and potential unsafe factors. In addition, manual labor cannot accurately guarantee the punctuality and completion of the filling task at a fixed point and quantity, resulting in irregular wear of the equipment due to untimely lubrication grease, causing unnecessary losses to the project. Summary of the invention

[0003] The object of the present invention is to provide a fully automatic grease multi-point pump filling system to solve at least one of the above-mentioned problems existing in the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A fully automatic butter multi-point pump filling system, comprising an oil filling device, an oil mixing tank and a multi-point pump, wherein the oil filling device injects butter into the oil mixing tank, the oil mixing tank is mounted on the upper end of the oil barrel of the multi-point pump through a bracket, and an oil outlet valve is provided between the oil mixing tank and the oil barrel;

[0006] A stirring motor is provided on the top of the oil mixing tank, a rotating shaft is provided in the oil mixing tank, the stirring motor drives the rotating shaft to rotate, a transverse connecting body is provided at the lower end of the rotating shaft, a plurality of stirring rods are arranged on the transverse connecting body at intervals, and a plurality of first heating rods extending upward are provided at the bottom of the oil mixing tank, and the positions of the first heating rods and the stirring rods are staggered;

[0007] Several distributors are installed on the base of the vertical lifting belt near the bearings. The multiple oil outlet ports of the multi-point pump are connected to oil pipes, which are connected to the oil inlets of the distributors. The multiple oil outlet ends of the distributors are respectively connected to oil distribution pipes, which are connected to the oil filling holes of the corresponding bearings on the vertical lifting belt.

[0008] In the technical solution, the oil filling device can fill the oil mixing tank with oil. Since the oil mixing tank is installed at the upper end of the oil barrel of the multi-point pump through a bracket, the horizontal space occupied by the equipment can be saved and the oil outlet valve can be conveniently set between the oil mixing tank and the oil barrel. There is no need to set a pump. The oil in the oil mixing tank can be injected into the oil barrel of the multi-point pump by opening the oil outlet valve. The structure is reasonably set and the complicated pipeline layout is simplified. Since the stirring motor drives the rotating shaft to rotate, the rotating shaft is connected to multiple stirring rods through a transverse connector, the butter in the oil mixing tank can be stirred and mixed. Combined with the first heating rod set at the bottom of the oil mixing tank, the butter can be heated while stirring, thereby avoiding the butter being too viscous under low temperature conditions and affecting the normal transportation of the butter. Since several distributors are installed near the bearing on the base of the vertical lifting belt, the distributor is mainly convenient for allocating a one-to-one delivery pipeline to each bearing. An oil pipeline is connected between the oil outlet port of the multi-point pump and the distributor to realize the primary transportation of the butter, and then the distributor and the oil distribution pipe realize the secondary distribution of the butter, thereby ensuring that each bearing can be filled with oil. In summary, this system can use a timer switch to control the multi-point pump, the stirring motor and the first heating rod as needed. The multi-point pump pressurizes the butter and distributes it through the distributor and then fills it into each predetermined bearing position to complete the lubrication process of the entire vertical lifting belt system. After the successful development of this system, the actual use effect is obvious, freeing the staff from heavy and mechanical labor, while eliminating the safety hazards in the manual filling operation process, ensuring that the equipment can automatically fill the butter to lubricate the bearings around the clock, reducing the irregular wear of the machinery caused by the weather and the untimely filling of personnel, causing irregular damage to the equipment and affecting the progress of on-site construction.

[0009] Furthermore, in order to continuously realize the oil filling of the oil mixing tank, the oil filling device includes an oil storage tank and an oil filling pump, and the oil filling pump realizes the connection between the oil storage tank and the oil mixing tank through an oil filling pipe.

[0010] Furthermore, in order to facilitate the installation of the oil injection pump, the oil injection pump is installed on the oil storage tank or the oil mixing tank.

[0011] Furthermore, in order to prevent the oil outlet of the oil storage tank from being blocked due to the ambient temperature, the oil outlet of the oil storage tank is connected to a heating shell, a metal heat pipe is arranged inside the heating shell, both ends of the metal heat pipe extend out of the heating shell respectively, the metal heat pipe extending out of the heating shell and located outside the oil storage tank is connected to the oil filling pipe, a second heating rod is arranged inside the heating shell, and a pressure relief valve is arranged on the heating shell. In a low temperature environment, the second heating rod can heat the inside of the heating shell and bake the metal heat pipe, so that the butter in the metal heat pipe can flow more smoothly, and the pressure relief valve can timely relieve the pressure of the heating shell.

[0012] Furthermore, in order to achieve a better stirring effect, a guide thread groove is provided on the rotating shaft, the upper end of the rotating shaft is rotatably connected to a drive plate, a guide column is provided on the oil mixing tank, the drive plate and the guide column are vertically slidably matched, a guide part is provided on the oil mixing tank, a roller is provided on the guide part, the roller is slidably matched with the guide thread groove, and a cam is provided on the output shaft of the stirring motor, and the rotation of the cam drives the drive plate to rise and fall along the guide column.

[0013] Specifically, the stirring motor drives the cam to rotate. When the cam pushes the driving plate upward, the roller of the guide part slides along the guide thread groove, and the rotating shaft rotates while the driving plate is lifted and lowered. The guide column can limit the rotation of the driving plate, so that the driving plate can only be lifted and lowered along the guide column under the drive of the cam, thereby driving the rotating shaft to lift and lower. Due to the sliding cooperation between the guide thread groove on the rotating shaft and the roller, the rotating shaft can be lifted and lowered while rotating synchronously, thereby realizing the driving of the stirring rod and improving the stirring effect.

[0014] Furthermore, in order to fully utilize the butter adhering to the inner wall of the oil mixing tank, a scraper is provided on the outermost stirring rod of the transverse connector, and the outer side of the scraper contacts the inner wall of the oil mixing tank. Driven by the stirring rod, the scraper moves along the inner wall of the oil mixing tank to scrape off the butter on the inner wall of the oil mixing tank for full utilization.

[0015] Furthermore, in order to ensure that the edge of the scraper is in full contact with the inner wall of the oil mixing tank and improve the oil scraping effect, a plurality of elastic support bodies are arranged between the scraper and the stirring rod.

[0016] Furthermore, according to field tests, in order to ensure the butter filling pressure, the oil delivery pipe includes two oil delivery branch pipes and one oil delivery main pipe, the oil inlet ends of the two oil delivery branch pipes are respectively connected to two adjacent oil outlet ports of the multi-point pump, the oil outlet ends of the two oil delivery branch pipes are respectively connected to the same oil delivery main pipe, and the oil outlet end of the oil delivery main pipe is connected to the oil inlet of the distributor. The double-line and single-line are used to ensure the butter filling pressure and filling flow, and then the distributor divides the flow to various parts.

[0017] Furthermore, after the butter is filled, in order to prevent excess oil from remaining in the pipeline, multiple oil pipelines are connected to return oil pipes through tees, and the return oil pipes are connected to the oil barrel of the multi-point pump through an oil return pump. The oil barrel of the multi-point pump is provided with an exhaust valve.

[0018] Furthermore, in order to better realize the installation of the mixing tank on the upper end of the oil barrel of the multi-point pump and facilitate the installation of the oil outlet valve between the two, the bracket includes an annular support plate and multiple support columns, the upper ends of the support columns are fixedly connected to the annular support plate, and the top of the oil barrel is located in the middle of the annular support plate.

[0019] The beneficial effects of the present invention are as follows: in this technical solution, the oil filling device can fill the oil mixing tank with oil. Since the oil mixing tank is installed on the upper end of the oil barrel of the multi-point pump through a bracket, it saves the horizontal space occupied by the equipment and can conveniently set an oil outlet valve between the oil mixing tank and the oil barrel. There is no need to set a pump. By opening the oil outlet valve, the oil in the oil mixing tank can be injected into the oil barrel of the multi-point pump. The structure is reasonably set and the complicated pipeline layout is simplified. Since the stirring motor drives the rotating shaft to rotate, the rotating shaft is connected to multiple stirring rods through a transverse connector, which can achieve the stirring and mixing of the butter in the oil mixing tank. Combined with the first heating rod set at the bottom of the oil mixing tank, the butter can be heated while stirring, thereby avoiding the butter being too viscous under low temperature conditions and affecting the normal transportation of the butter. Since several distributors are installed near the bearings on the base of the vertical lifting belt, the distributor is mainly used to facilitate the allocation of one-to-one delivery pipelines for each bearing. An oil pipeline is connected between the oil outlet port of the multi-point pump and the distributor to realize the primary delivery of butter, and then the distributor and the oil distribution pipe realize the secondary distribution of butter, so as to ensure that each bearing can be filled with oil. In summary, this system can use a timing switch to control the multi-point pump, the stirring motor and the first heating rod as needed. The multi-point pump pressurizes the butter and distributes it through the distributor and then fills it into each predetermined bearing position to complete the lubrication process of the entire vertical lifting belt system. After the successful development of this system, the actual use effect is obvious, which frees the staff from heavy and mechanical labor, and eliminates the safety hazards in the manual filling operation process, ensuring that the equipment can realize automatic filling of butter to lubricate the bearings around the clock, reducing the unconventional wear of the machinery caused by weather and untimely filling of personnel, causing unconventional damage to the equipment and affecting the progress of on-site construction.

Since the stirring motor 5 drives the rotating shaft 6 to rotate, the rotating shaft 6 is connected to multiple stirring rods 8 through the transverse connector 7, the butter in the oil mixing tank 1 can be stirred and mixed. Combined with the first heating rod 9 set at the bottom of the oil mixing tank 1, the butter can be heated while stirring, thereby avoiding the butter being too viscous under low temperature conditions and affecting the normal transportation of the butter.
