Description

Technical Field

[0001] The utility model relates to the technical field of grease pumps, in particular to a grease barrel pumping device. Background Art

[0002] Grease pump devices are widely used in metallurgy, mining, coal, electricity, cement, chemical industry and other fields. They are mainly used for filling or pressurizing high-viscosity, low-fluidity grease materials. They are mainly composed of pump frame, pneumatic motor, oil pump assembly, pressure plate assembly, control system, etc. When the grease pump device extracts the grease in the barrel, the pressure plate assembly is pressed down to press the grease in the barrel into the oil pump assembly, and the grease is extracted with the help of the oil pump assembly.

[0003] In the prior art, for example, application number CN202220440426.9 discloses a pneumatic grease pump that facilitates air-controlled exhaust.

[0004] In the prior art, when extracting grease, the grease pump device mostly just aligns the grease barrel and the pressure plate assembly to extract. When extracting a large barrel of grease, some simple clamps are used to fix the grease barrel as in the above patent, so that the grease barrel will not shake easily during the extraction process. However, when extracting a small barrel of grease, such as a 1kg grease barrel, the operator usually just opens the grease barrel and aligns it with the pressure plate, then presses down, and then adjusts the grease barrel during the pressing process to ensure that the pressure plate can smoothly enter the grease barrel. This operation is dangerous. During the pressing process, it is easy to cause injury to the operator's fingers, and most of the entire pumping process often requires the operator to fix the grease barrel with his hands, including alignment before pumping, and the process of moving the pressure plate assembly upward after pumping is completed. The grease barrel also needs to be fixed. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] Embodiment 1:

[0030] Figures 1 to 4 As shown, a grease barrel pumping device includes a base 301, two lifting columns 302 are vertically and parallelly installed on the upper side of the base 301, the top ends of the two lifting columns 302 are connected through a mounting plate 303, and an equipment hole 304 that runs through the upper and lower sides is arranged in the middle of the mounting plate 303, a pump body 100 is installed on the upper side of the mounting plate 303, a liposuction tube 200 of the pump body passes through the equipment hole 304 downward, and a pressure plate is detachably connected to the lower end of the liposuction tube 200; two clamping plates 101 with semicircular arc-shaped horizontal cross-sections are installed on the upper side of the base 301, the two clamping plates 101 are arranged oppositely to form a cylindrical first fixing hole 102 between the two clamping plates 101, and the first fixing hole 102 is aligned with the pressure plate for fixing the grease barrel; one side of the two clamping plates 101 is horizontally rotatably connected by a hinge 103, and the other side is connected by a locking member; the lower end of at least one clamping plate 101 is connected to the base 301. The lower end of at least one clamp 101 is provided with a mounting hole 104 for fixing the clamp 101 on the base 301. When using the protective clamp, fix one clamp 101 of the protective clamp on the base 301, and then open the two clamps 101 around the hinge 103, so that it is convenient to put the grease barrel between the two clamps 101. After the placement is completed, merge the two clamps 101 and fix the two clamps 101 by a locking member, so that the grease barrel can be well fixed. The grease barrel and the pressure plate of the grease pump can be quickly aligned and positioned. The outer wall of the grease barrel can also be protected with the help of the two clamps 101 to prevent the grease barrel from exploding during the extraction process.

[0031] The locking member includes a rotating shaft 105, a fixed shaft 106 and a locking plate 107. The rotating shaft 105 and the fixed shaft 106 are respectively arranged on the outer wall of the two clamping plates 101 away from the hinge 103, and the rotating shaft 105 and the fixed shaft 106 are arranged in parallel. The side surface of one end of the locking plate 107 is provided with a rotating hole 108 running through the upper and lower sides, and the lower side of the other end is provided with a notch 109. The locking plate 107 is rotatably connected to the rotating shaft 105 through the rotating hole 108, and the locking plate 107 is clamped on the upper side of the fixed shaft 106 through the notch 109. With such a configuration, the operator can fix the grease barrel with one hand. He only needs to push the locking plate 107 upwards to rotate the locking plate 107 around the rotating shaft 105, move the position of the notch 109 away from the position of the fixed shaft 106, and then move the splint 101 that is not fixed to the base 301, and then fit the grease barrel to the inner wall of the splint 101, and then merge the two splints 101 together, and then move the locking plate 107 again to make the notch 109 of the locking plate 107 and the fixed shaft 106 snap connected, and the grease barrel is fixed.

[0032] The spacing between the notches 109 decreases gradually from bottom to top. With such a configuration, when the fixed shaft 106 gradually enters the notch 109, the ends of the two clamping plates 101 that were not originally closely fitted will gradually move closer together, thereby clamping and fixing the grease barrel.

[0033] The outer walls of the two clamping plates 101 away from the hinge 103 are respectively provided with a first plane 110 and a second plane 111, and the rotating shaft 105 and the fixed shaft 106 are respectively provided on the first plane 110 and the second plane 111. By providing the first plane 110 and the second plane 111, it is possible to provide a mounting surface for the rotating shaft 105 and the fixed shaft 106, and at the same time, the locking plate 107 can be rotated in contact with the first plane 110 and the second plane 111 when rotating.

[0034] The first plane 110 and the second plane 111 are both provided with first threaded holes, and the outer walls of the rotating shaft 105 and the fixed shaft 106 are both provided with external threads matching the first threaded holes, and the rotating shaft 105 and the fixed shaft 106 are respectively installed in the two first threaded holes through the external threads. By providing the first threaded holes, the fixed shaft 106 and the rotating shaft 105 can be installed on the first plane 110 and the second plane 111 by thread matching. Such an installation method is not only convenient, but also firmly installed, and easy to repair when a fault occurs.

[0035] The upper side of the locking plate 107 is bent toward a side away from the clamping plate 101 to form a supporting plate 112. By providing the supporting plate 112, when the locking plate 107 is pushed upward, it can be pushed upward by placing a finger on the lower side of the supporting plate 112.

[0036] The mounting hole 104 is a third threaded hole. The base 301 is provided with a through hole that passes through the upper and lower sides. When the third threaded hole and the through hole are aligned, they are fixedly connected by bolts 114. With such a configuration, any one of the clamping plates 101 can be fixed to the base 301 by bolts 114, so that the grease barrel can be installed by opening the other clamping plate 101 from the side. The two clamping plates 101 can also be fixed to the base 301 by bolts 114, so that the two clamping plates 1 form a fixed first fixing hole 102, and the grease barrel can be placed from the top of the first fixing hole 102 into the first fixing hole 102 to complete the fixing of the grease barrel.

[0037] Embodiment 2:

[0038] like Figure 5-7 As shown, the pressure plate includes a pressure plate body 201, and an extrusion hole 202 penetrating the upper and lower sides is arranged in the middle of the pressure plate body 201, and a mounting column 203 is installed on the upper side of the pressure plate body 201, and a first mounting hole 204 penetrating the upper and lower sides is arranged on the mounting column 203, and the first mounting hole 204 is aligned and connected with the extrusion hole 202, and an exhaust pipe 205 and a blow pipe 206 connected with the extrusion hole 202 are arranged on the mounting column 203, and a valve for controlling the on-off of the exhaust pipe 205 is installed on the exhaust pipe 205; a one-way valve for one-way conduction toward the extrusion hole 202 is arranged on the blow pipe 206, and the blow pipe 206 is connected to an external air supply device. When using the split pressure plate for grease extraction, the extraction pipe of the grease pump is connected to the first mounting hole 204, and when the pressure plate body 201 is pressed down, the grease enters the extraction pipe through the extrusion hole 202 and the first mounting hole 204 in turn, and then is pumped out by the grease pump. By providing the exhaust pipe 205, the excess air between the platen body 201 and the grease can be discharged through the exhaust pipe 205 at the initial stage of the platen body 201 being pressed down. After the discharge is completed, the grease can be prevented from being discharged from the exhaust pipe 205 by closing the valve. By providing the air blowing pipe 206, after the grease is pumped, air can be blown toward the extrusion hole 202 through the air blowing pipe 206 by an external air supply device. In this way, the grease barrel can be in a normal air pressure state or a pressurized state during the upward movement of the platen body 201, and the grease barrel can be prevented from moving up with the platen body 201. By providing the one-way valve, the grease can be prevented from entering the air blowing pipe 206 during the downward movement of the platen body 201.

[0039] The upper side of the mounting column 3 is provided with an exhaust hole 207 and an air blowing hole 208 connected to the extrusion hole 202, the exhaust pipe 205 is connected to the exhaust hole 207, and the air blowing pipe 206 is connected to the air blowing hole 208. By providing the exhaust hole 207, it is convenient to connect the exhaust pipe 205, so that the air in the extrusion hole 202 and the lower side of the pressure plate body 201 can be discharged through the exhaust hole 207 and the exhaust pipe 205. By providing the air blowing hole 208, after the grease extraction is completed, the external air supply device blows the air into the extrusion hole 202 through the air blowing pipe 206 and the air blowing hole 208, so that the pressure plate body 201 and the grease barrel are more easily separated.

[0040] Several locking screw holes 209 connected to the first mounting hole 204 are arranged around the side of the mounting column 203, and locking screws are arranged in the several locking screw holes 209 in a threaded matching manner. By setting the locking screw holes 209 and the locking screws, when the split pressure plate is installed on the grease pump, the extraction tube of the grease pump is inserted into the first mounting hole 204, and the locking screw is screwed so that the locking screw enters the first mounting hole 204 and touches the outer wall of the extraction tube, so that the extraction tube can be locked in the first mounting hole 204. With the help of different lengths of the locking screw entering the first mounting hole 204, extraction tubes of various diameters can be adapted, thereby improving the practicality of the split pressure plate. Compared with the pressure plate installed integrally on the conventional grease pump, the utility model can be installed on a grease pump that does not pass through at any time for use.

[0041] A sealing ring groove 210 is provided in the hole wall depression surrounding the first mounting hole 204, a sealing ring 211 is installed in the sealing ring groove 210, and the inner wall of the sealing ring 211 protrudes from the sealing ring groove 210. By providing the sealing ring groove 10 and the sealing ring 211, the outer wall of the extraction tube and the hole wall of the first mounting hole 204 can be sealed, thereby preventing the grease in the grease barrel from leaking out from the outer wall of the extraction tube and the hole wall of the first mounting hole 204. The sealing ring 211 can be positioned by the sealing ring groove 210, and sealing rings 211 of different specifications can be replaced according to the diameter of the extraction tube for sealing.

[0042] A sealing sheet 212 is installed on the lower side of the platen body 201. A first through hole 213 aligned with the extrusion hole 202 is provided in the middle of the sealing sheet 212. The edge of the sealing sheet 212 protrudes from the edge of the platen body 201. By providing the sealing sheet 212, during the pressing process of the platen body 201, the edge of the sealing sheet 212 fits against the inner wall of the grease barrel to seal the gap between the edge of the platen body 201 and the inner wall of the grease barrel, thereby ensuring that all the grease in the grease barrel is pumped out through the extrusion hole 202. The sealing sheet 212 also acts as a scraper to scrape off all the grease on the inner wall of the grease barrel.

[0043] The sealing sheet 212 is installed on the lower side of the pressure plate body 201 through the pressing sheet 214. A second through hole 215 aligned with the extrusion hole 202 is provided in the middle of the pressing sheet 214. The diameter of the pressing sheet 214 is smaller than the diameter of the pressure plate body 201. The pressing sheet 214 is installed on the lower side of the pressure plate body 201 by fixing screws so that the sealing sheet 212 is installed between the pressing sheet 214 and the pressure plate body 201. The sealing sheet 212 can be well fixed on the lower side of the platen body 201 by the pressing sheet 214. The pressing sheet 214 is provided with a first circular hole 219 penetrating the upper and lower sides, and the sealing sheet 212 is provided with a second circular hole 220 penetrating the upper and lower sides. The lower side of the platen body 201 is provided with a mounting screw hole 218. When installing the sealing sheet 212, align the second circular hole 220 of the sealing sheet 212 with the mounting screw hole 218, align the first circular hole 219 and the second circular hole 220 of the pressing sheet 214, and then pass the fixing screws through the first circular hole 219 and the second circular hole 220 in sequence, and connect with the mounting screw hole 218 by thread matching. In order to firmly install the pressing sheet 214 and the sealing sheet 212, a plurality of the first circular hole 219, the second circular hole 220, the mounting screw hole 218 and the fixing screws are matched.

[0044] The lower side of the pressure plate body 21 is formed with a positioning ring 216 protruding downward around the extrusion hole 22, and the hole walls of the first through hole 213 and the second through hole 215 are both in contact with the outer wall of the positioning ring 216. By providing the positioning ring 216, the sealing sheet 212 and the pressing sheet 214 can be quickly positioned and installed, and the inner walls of the pressing sheet 214 and the sealing sheet 212 can be prevented from blocking the extrusion hole 22.

[0045] The diameter of the first mounting hole 204 is smaller than the diameter of the extrusion hole 202, and the connection between the first mounting hole 204 and the extrusion hole 202 is transitionally connected via an inclined surface 217. By providing the inclined surface 217, the grease in the extrusion hole 202 can be guided into the first mounting hole 204, so as to be extracted through the extraction tube.

By providing the middle connecting plate 306, the middle parts of the two lifting columns 302 can be supported, and the structure of the two lifting columns 302 is more stable in cooperation with the mounting plate 303. By providing the middle part of the middle connecting plate 306 in an arc shape, the middle connecting plate 306 can be kept away from the liposuction tube of the pump body.

Through the cooperation of the plurality of first screw holes 311 and the fixing through hole 310, the end of the middle connecting plate 306 and the upper end of the fixing column 307 can be fixed at multiple points, thereby improving the connection stability between the fixing column 307 and the middle connecting plate 306. The method of fixing with the first screw is not only convenient to operate, but also easy to disassemble and install, and convenient to maintain.
