Description

Technical Field

[0001] The utility model relates to the technical field of oil supply equipment, in particular to an automatic lifting device for an oil pump. Background Art

[0002] Equipment is usually lubricated by extracting grease from the oil barrel using a grease pump. For large equipment in steel mills, the amount of oil to be extracted is large, and the efficiency of using only a grease pump is too low. Therefore, an oil pump is usually used to extract and fill the oil. The current operation is to place the oil pump on the oil barrel, connect the oil inlet of the oil pump to the oil inlet hose, and then insert it into the oil barrel. The oil outlet of the oil pump is connected to the oil outlet hose to fill the equipment with oil and lubricate it. When the grease in the oil barrel under the oil pump is exhausted, the oil pump needs to be removed and replaced with a new grease barrel. The oil pump weighs 50 kg and has a lifting height of 1300 mm. It requires three people to lift it to the new grease barrel. The handling process is labor-intensive and inefficient. Utility Model Content

[0005] Slope frames are hinged on both side walls of the frame near the inlet and outlet, a locking mechanism is provided between the frame and the slope frame, and flat rollers are provided at the bottom of the frame and the slope frame to support the oil drum and facilitate the movement of the oil drum;

[0006] An upper flip frame is provided at the top of the frame, and a mounting plate for installing the oil pump is fixed on the upper flip frame. One end of the upper flip frame is hinged to the top of the frame, and the other end is hinged to a telescopic mechanism. The telescopic mechanism is hinged to the middle part of the frame. The upper flip frame is driven by the telescopic mechanism to be in an inclined open state or a horizontal closed state.

[0007] The technical problem to be solved by the present invention can also be achieved through the following technical solutions. The above-mentioned automatic lifting device for an oil pump has several partition holes in the middle of the frame, and partition rods are inserted into the partition holes to divide the oil barrel storage space into several individual oil barrel storage spaces.

[0008] The technical problem to be solved by the present invention can also be achieved through the following technical solutions. The above-mentioned automatic lifting device for an oil pump, the locking mechanism includes a fixing rod, a fixing hole and a positioning hole, the fixing holes are opened on both sides of the frame, the positioning hole is opened in the middle of the ramp frame, and the fixing rod is inserted into the fixing hole and the positioning hole.

[0009] The technical problem to be solved by the present invention can also be achieved through the following technical solutions: the above-mentioned automatic lifting device for the oil pump has a frame with a plurality of universal wheels installed at the bottom to facilitate the free movement of the frame.

[0010] The technical problem to be solved by the present invention can also be achieved through the following technical solutions: in the above-mentioned automatic lifting device for an oil pump, two telescopic mechanisms are symmetrically arranged, and both telescopic mechanisms use cylinders.

[0011] Compared with the prior art, the beneficial technical effects of the present invention are:

[0012] (1) The automatic lifting device for the oil pump can automatically lift the oil pump through the cylinder and can move the oil barrel up and down through the ramp frame. There is no need to use other tools to move the oil barrel into the frame, nor is there any need to manually lift the oil pump onto the oil barrel, thereby reducing labor intensity and improving labor efficiency. Flat rollers are provided at the bottom of the frame and the ramp frame to support the oil barrel and facilitate its movement. The rollers can reduce the friction between the oil barrel and the frame, making it easier to push the oil barrel up and down the frame.

[0013] (2) The dividing rod is used to divide the frame into multiple spaces, each of which is used to place an oil barrel. The rod can also limit the horizontal movement of the oil barrel, so that the oil barrel is fixed in the two spaces. This prevents the oil barrel from shifting during the refueling operation, ensuring the normal operation of the refueling operation. In addition, the multiple spaces also allow the device to carry multiple barrels of oil, eliminating the need to frequently return to the oil depot to fetch oil.

[0014] (3) The device only needs two cylinders to lift the oil pump. By using the lever principle, the hinge point of the cylinder is designed to be close to the middle position of the upper flip frame, which can further shorten the extension of the cylinder, or the lifting height of the upper flip frame can be higher when the extension is the same, making it more convenient to replace the oil barrel.

[0018] The following further describes the specific technical solutions of the present invention with reference to the accompanying drawings, so as to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to their rights.

[0019] Example 1, reference Figure 1-2 An automatic lifting device for an oil pump includes a frame 1, which is formed into a substantially square frame structure. An oil barrel storage space for accommodating oil barrels is formed in the frame 1, and an inlet and outlet are formed on both sides of the frame 1 for facilitating the entry and exit of oil barrels into and out of the oil barrel storage space.

[0020] A ramp frame 4 is hinged on both side walls of the frame 1 near the inlet and outlet. The top outer side surface of the ramp frame 4 has a straight chamfer, so that when the ramp frame 4 is opened horizontally, it is convenient for the oil drum to enter the frame 1. A locking mechanism is provided between the frame 1 and the ramp frame 4. The locking mechanism includes a fixing rod 8, a fixing hole 9 and a positioning hole 11. The fixing hole 9 and the positioning hole 11 are both circular through holes. The fixing rod 8 is a round rod. The fixing holes 9 are provided on both sides of the frame 1. The positioning hole 11 is provided in the middle of the ramp frame 4. The fixing rod 8 is inserted into the fixing hole 9 and the positioning hole 11.

[0021] At the bottom of the frame 1 and the slope frame 4, flat rollers 3 are provided to support the oil drum and facilitate the movement of the oil drum. The flat rollers 3 are hinged to the frame 1.

[0022] An upper flip frame 5 is provided at the top of the frame 1. The upper flip frame 5 is formed into a roughly square frame 1. A mounting plate 12 for mounting an oil pump is fixedly provided on the upper flip frame 5. The mounting plate 12 is formed into a roughly square plate-shaped structure. One end of the upper flip frame 5 is hinged to the top of the frame 1, and the other end is hinged to a telescopic mechanism. The telescopic mechanism is hinged to the middle of the frame 1. Two telescopic mechanisms are symmetrically provided. Both telescopic mechanisms use a cylinder 6. The telescopic mechanism drives the upper flip frame 5 to a tilted open state or a horizontal closed state.

[0023] A plurality of partition holes 10 are provided in the middle of the frame 1 , into which partition rods 7 are inserted for partitioning the oil drum storage space into a plurality of individual oil drum storage spaces. The partition rods 7 are formed into a generally round rod-shaped structure.

[0024] In order to facilitate the free movement of the frame 1, a plurality of universal wheels 2 are installed at the bottom of the frame 1 to facilitate the free movement of the frame 1.

[0025] The working principle of the oil pump automatic lifting device is:

[0026] When in use, install the oil pump on the mounting plate 12, connect the oil inlet and outlet of the oil pump to the oil inlet hose and the oil outlet hose (not shown) respectively, connect the air pipe of the cylinder 6, pull out the fixing rod 8 and the dividing rod 7, turn the ramp frame 4 to both sides, so as to form a slope for the oil barrel to be put up and down, start the cylinder 6, turn the flip frame 5 upward, so as to lift the oil pump, lift one side of the oil barrel, push the frame 1, insert the ramp frame 4 into the bottom of the oil barrel, and then switch the universal wheel 2 to the brake state, push Move the oil barrel into the oil barrel storage space of the frame 1. The oil barrel can be put up and down at either end of the frame 1. After pushing the two oil barrels into the oil barrel storage space of the frame 1, flip the ramp frame 4 up, and insert the fixing rod 8 into the fixing hole 9 and the positioning hole 11 to fix the ramp frame 4 on the frame 1. Insert the dividing rod 7 into the dividing hole 10, insert the oil inlet hose of the oil pump into the oil barrel below, start the cylinder 6 to retract, and return the flip frame 5 to its original position. At this time, oil filling and lubrication work can be carried out;

[0027] When the grease in the oil barrel under the oil pump is used up, lift the flip frame 5, flip the slope frame 4 outward, pull out the dividing rod 7 and the fixing rod 8, take out the empty barrel, push another oil barrel under the oil pump, connect the oil inlet hose, and then place the empty barrel in another empty space in the oil barrel storage space of the frame 1, flip up the slope frame 4, insert the dividing rod 7 and the fixing rod 8, and return the flip frame 5 to its original position, thereby completing the switching of the oil barrels.

[0028] It should be noted that the device only needs to use two cylinders 6 to complete the lifting of the oil pump. By utilizing the principle of leverage, the hinge point of the cylinder 6 is designed to be close to the middle position of the upper flip frame 5, which can further shorten the extension of the cylinder 6, or the lifting height of the upper flip frame 5 can be higher when the extension amount is the same, making it more convenient to replace the oil barrel.

[0029] In addition, the oil pump can also be lifted vertically, but vertical lifting requires four cylinders 6 connected to the four corners of the oil pump.
