Description

Technical Field

[0001] The utility model relates to the field of bridge crane trolleys, in particular to a non-electric automatic lubrication system for bridge crane trolleys. Background Art

[0002] At present, the main trolley and the rope trolley of the bridge crane rely on the wire rope in the machine room for traction, which is a completely mechanical mechanism, resulting in the pulleys, wheels, wire rope rollers, etc. being completely lubricated manually. The wire rope speed of the port bridge grab ship unloader and the quay crane is very fast, and its working environment and structure are very special. Each time manual lubrication is performed, the equipment needs to be stopped at a fixed position, which seriously affects the operation time and personnel safety.

[0003] The above problems have caused great difficulties in the maintenance of equipment, especially for some automated and intelligent port designs, because the trolley still needs manual lubrication, which cannot meet the real automation requirements. In addition, manual lubrication increases the labor cost in the production process, and the lubrication amount depends on the judgment of the manual supervisor. The lubrication effect is very unsatisfactory, which seriously affects the service life of the equipment and has a serious impact on the production efficiency of the equipment.

[0004] Due to factors such as the trolley's high speed, limited space and lack of electricity, there are currently two lubrication methods in the industry.

[0005] The first method is manual lubrication, which has high personnel costs, low efficiency, poor lubrication effect, and great safety hazards. The main manifestations are that the equipment needs to be shut down, affecting work efficiency, high-altitude operations in a small space, and the equipment lubrication amount and lubrication time are completely dependent on human subjective judgment, which requires a large investment in labor costs. Therefore, this method has great disadvantages.

[0006] The second method is to use solar charging to set up a lubrication pump. The problems with this method are: 1. The lubrication station is large in size, the space for the mechanism is very small, and the placement location is very limited. 2. The port equipment is not all placed due south, and the sun exposure time is very short. Moreover, the trolley's route is blocked by other equipment for part of the time, and the charging efficiency is very low. 3. The built-in control system needs to be powered all the time, and the power loss is very large, which is not enough to cover the expenses. 4. It cannot be automatically lubricated according to the running time of the trolley, and can only be lubricated regularly according to the calendar time, which will result in very uneven lubrication, more or less. 5. The problem of battery replacement, because long-term emptying has a serious impact on battery life and the cost will also increase.

[0007] The traditional lubrication method requires that grease be added to the bearing until it overflows, which will cause very serious pollution to the equipment. The trolley is suspended under the beam, and the grease will fall from a high altitude, polluting the road and the ocean, and also causing great hidden dangers to personnel safety. Traditional lubrication methods have very big problems, which is also the pain point encountered by users. There is currently no good lubrication method.

[0008] As the country places increasingly higher demands on automation in heavy industries such as docks, power plants, and steel mills, improving production efficiency and realizing intelligence have placed higher demands on some special institutions. Summary of the invention

[0009] In order to make up for the above deficiencies, the utility model provides a non-electric automatic lubrication system for a bridge crane trolley.

[0010] The utility model is realized through the following technical solutions: a non-electric automatic lubrication system for a bridge crane trolley, including a non-electric lubrication pump system and an oil control device;

[0011] The non-electric lubrication pump system includes an oil barrel, an oil scraper device is arranged inside the oil barrel, an oil supply valve block is arranged at the bottom of the oil barrel, a mounting base is arranged at the bottom of the oil supply valve block, an oil supply piston is arranged inside the oil supply valve block, a guide rod is inserted into the outer side of the oil supply piston, a return spring is sleeved on the guide rod, the guide rod is connected to a flexible anti-collision connecting rod, a bearing seat is arranged on the top of the flexible anti-collision connecting rod, and a rolling bearing is arranged in the bearing seat; the oil control device is a control block.

[0012] A further improvement of the utility model is that the non-electric lubrication pump system is installed at the edge of the trolley.

[0013] A further improvement of the utility model is that the oil control device controls the oil output of the non-electric lubrication pump system.

[0014] A further improvement of the utility model is that the lubrication frequency is determined according to the number of control blocks installed.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. Functional advantages:

[0017] It can solve the traditional manual lubrication method, realize automation requirements, better protect the bearings, and greatly extend the service life of the bearings.

[0018] 2. Cost advantage:

[0019] This design solution uses about 20% more materials than traditional manual lubrication and 10% less than the solar power generation solution, but the labor cost savings are 80% lower than both.

[0020] This design scheme fully realizes online lubrication. The equipment does not need to be shut down for maintenance, which reduces downtime and increases production efficiency. According to the calculation that the main equipment can generate 600,000 benefits per day, it takes 0.5 days to lubricate the trolley once, and it is lubricated every 15 days, which means that it only needs to be shut down for 1 day per month for maintenance. This can save costs of 600,000 per month.

[0021] 3. Use and maintenance advantages:

[0022] The traditional lubrication method requires at least 8 hours of maintenance per month, while the new design only requires manual grease addition to the lubrication pump once a month, 30 minutes each time, which means only 15 minutes per month, a 96.9% reduction in traditional lubrication time. The lubrication effect is also synchronized with the equipment operation time, and the bearings will be in the best condition.

[0023] In contrast, the use and maintenance costs of the utility model have huge advantages.

[0024] 4. Safety advantages in energy saving and emission reduction:

[0025] Because the equipment is located 50 meters high and has a complex steel structure, the traditional lubrication method requires manual climbing onto a trolley to perform the operation, which is very prone to safety accidents.

[0026] The power-free automatic lubrication system of the utility model can accurately control the oil output, reduce bearing wear, save the use of grease, and eliminate safety hazards from the source. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 It is a schematic diagram of the structure of the utility model.

[0029] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0030] like Figure 1 As shown, a non-electric automatic lubrication system for a bridge crane trolley includes a non-electric lubrication pump system and an oil control device;

[0031] The non-electric lubrication pump system includes an oil barrel 1, an oil scraper device 2 is arranged inside the oil barrel 1, an oil supply valve block 3 is arranged at the bottom of the oil barrel 1, a mounting base 4 is arranged at the bottom of the oil supply valve block 3, an oil supply piston 5 is arranged inside the oil supply valve block 3, a guide rod 6 is inserted into the outer side of the oil supply piston 5, a return spring 7 is sleeved on the guide rod 6, the guide rod 6 is connected to a flexible anti-collision connecting rod 8, a bearing seat 9 is arranged on the top of the flexible anti-collision connecting rod 8, and a rolling bearing 10 is arranged in the bearing seat 9; the oil control device is a control block 11.

[0032] Working method:

[0033] The non-electric lubrication pump system is installed at the edge of the trolley. When the trolley moves, the non-electric lubrication pump system moves with the trolley. When the rolling bearing 10 at the head of the non-electric lubrication pump system contacts the control block 11, the rolling bearing 10 rolls along the curved surface of the control block 11. At this time, the lateral force will be converted into axial force, and the guide rod 6 will compress the reset spring 7, which will push the oil supply piston 5 to move. When the rolling bearing 10 reaches the highest point of the curved surface of the oil control block 11, the reset spring 7 reaches the maximum compression, the single stroke of the oil supply piston 5 ends, and the grease is pushed out. When the rolling bearing 10 continues to move along the curved surface of the oil control block 11, the reset spring 7 pushes the oil supply piston 5 out. At this time, the entire stroke ends and waits for the next oil control block 11 to appear. An oil control device controls the non-electric lubrication pump system to discharge oil once, and 1-8ml of oil is discharged each time. The oil output is adjusted according to the compression of the oil supply piston 5. The lubrication frequency is determined by the number of oil control devices installed.

[0034] The solution of the utility model is to use the kinetic energy of the trolley itself, change the structure of the lubrication pump, and provide power for the lubrication pump by installing an oil control device on the beam. This method completely lubricates according to the running time of the trolley, solves the problem of motion linkage, and completely realizes the unification of consumption and lubrication. According to the density of the oil control device, the action frequency of the non-electric lubrication pump system is adjusted, and the lubrication amount is finally adjustable. The maximum pressure of the non-electric lubrication pump system can reach 15MPa, and 2# and below extruded lithium esters can be used. The non-electric lubrication pump system is designed according to the mechanism, and the installation position does not affect the operation of other equipment. There is no need to change the original structure of the main equipment, which reduces other investment costs. The lubrication amount of different mechanisms such as trolley pulleys, wheels and rollers is different. Classification and control of lubrication points with the same structure, the same oil cavity size, the same running time, and the same grease loss can effectively solve the problem of uneven lubrication. Online lubrication, without stopping, greatly improves the production efficiency of the main equipment, greatly reduces labor costs, greatly reduces safety hazards, greatly extends the service life of bearings, and greatly realizes automation. The utility model can be widely used in the maintenance of heavy equipment without special power mechanisms in the fields of ports, power plants, metallurgy, mining, etc., and has high application and economic value.
