Description

Technical Field

[0001] This utility model relates to the technical field of screw pump unit facilities, specifically to an adjustable safety cover for screw pump units. Background Technology

[0002] Screw pump units are used in industrial production processes to transport high-viscosity liquids, pastes, greasy substances, semi-solid materials, and media containing solid particles. When using screw pump units, a safety cover is generally used to cover the coupling to isolate it and prevent workers from coming into contact with it while it is rotating, thus ensuring safety.

[0003] The safety covers used in existing screw pump units are usually made of sheet metal and then simply processed to form a certain enclosed space, mainly to block the coupling, especially the position where the elastic body of the coupling is installed;

[0004] The shortcomings of the existing technical solutions are as follows: Current industry standards clearly state that the safety cover for screw pump units must cover both the rotating shaft and the coupling. However, due to the fixed length of existing safety covers, they cannot completely shield the rotating shaft of the screw pump and prime mover, posing a safety hazard. Furthermore, the length of existing safety covers is essentially fixed and cannot be adjusted arbitrarily, limiting their use to a certain length range. This results in a wide variety of safety cover specifications, increasing costs and hindering production management. Additionally, if it is necessary to observe the working status of the coupling during operation, the safety cover must be lifted upwards for observation. During this process, the safety cover inevitably comes into contact with the rotating coupling, increasing the safety hazard. Utility Model Content

[0030] like Figures 1-5As shown, an adjustable safety cover for a screw pump unit includes a fixed end 1 and a movable end 2 connected within the fixed end 1. The movable end 2 can move back and forth within the fixed end 1 to adjust the length of the safety cover to accommodate different couplings and rotating shafts. The fixed end 1 includes a fixed end panel 101, a fixed end side panel 102, and a fixed end cover 103. The fixed end panel 101 is inverted "U" shaped, and the fixed end cover 103 is arc-shaped. There are two fixed end side panels 102, with both sides of the fixed end panel 101 fixedly connected to the fixed end side panels 102. The movable end 2 of the safety cover is movably connected to the fixed end cover 103. It includes a movable end panel 201, a movable end side panel 202, and a movable end cover 203. The movable end panel 201 is inverted "U"-shaped, and the movable end cover 203 is arc-shaped. The outer diameter of the movable end panel 201 is slightly smaller than the outer diameter of the fixed end panel 101. There are two movable end side panels 202. The two sides of the movable end panel 201 are fixedly connected to the movable end side panel 202, and the movable end side panel 202 is movably connected to the movable end cover 203. A groove 3 is provided at the bottom of both the fixed end side panel 102 and the movable end side panel 202 for subsequent... The entire safety cover is secured; a hinge 18 is provided on one side of both the fixed end cover 103 and the movable end cover 203, and a fastener 17 is provided on the other side of both the fixed end cover 103 and the movable end cover 203. One side of the fixed end cover 103 is connected to one of the fixed end side panels 102 via the hinge 18, and the other side of the fixed end cover 103 is connected to the other fixed end side panel 102 via the fastener 17. One side of the movable end cover 203 is connected to one of the movable end side panels 202 via the hinge 18, and the other side of the movable end cover 203 is connected to the other fixed end side panel 102 via the fastener 17. The movable end side panels 202 are connected by a buckle 17. A handle is provided above the fixed end cover 103 and the movable end cover 203. The fixed end cover 103 and the movable end cover 203 are connected by the handle. Through the cooperation of the handle, buckle 17, and hinge 18, the fixed end cover 103 and the movable end cover 203 can be opened and closed freely without lifting the entire safety cover, making it easy to observe the working status of the coupling and preventing contact between the safety cover and the rotating coupling, thus increasing safety. An adjustment component is provided between the fixed end 1 and the movable end 2 of the safety cover, used to adjust and fix the length of the safety cover.

[0031] The adjustment assembly includes two sandwich plates 4, each disposed inside the fixed end side panel 102. One end of each sandwich plate 4 is fixedly connected to the fixed end panel 101. A gap is left between the sandwich plates 4 and the fixed end side panel 102 to facilitate the subsequent movement of the movable end side panel 202 within the gap. Holes 8 are correspondingly provided on the sides of the sandwich plates 4 and the fixed end side panel 102 away from the fixed end panel 101. A boss 5 is fixedly connected to the sandwich plate 4. The boss 5 has a hexagonal hole, in which a nut 7 is disposed. A bolt 6 is disposed in the hole 8. A groove 9 is provided on the movable end side panel 202. The second groove 9 is a waist-shaped groove. The movable end side panel 202 is placed between the fixed end side panel 102 and the interlayer plate 4. The bolt 6 passes through the second groove 9 and the hole 8 and cooperates with the nut 7. Through the cooperation between the interlayer plate 4, the boss 5, the bolt 6, the nut 7 and the second groove 9, the movable end side panel 202 can be freely pushed and pulled between the interlayer plate 4 and the fixed end side panel 102, so that the length of the entire safety cover can be flexibly adjusted. A blocking component is provided on the side of the movable end side panel 202 near the movable end end panel 201. The blocking component is used to block the exposed part of the second groove 9 to prevent rotating objects inside the safety cover from flying out of the second groove 9.

[0032] The shielding assembly includes a spring support column 12, which is used for subsequent spring installation. The spring support column 12 is located between the second slot 9 and the movable end panel 201 and is flush with the second slot 9. Partitions 13 are provided on the upper and lower sides of the spring support column 12. The partitions 13 are "L"-shaped, forming a side "U"-shaped channel between the two partitions 13. One end of both the spring support column 12 and the partitions 13 is fixedly connected to the movable end panel 201. A spring 16 is fitted onto the spring support column 12. A spring baffle is provided between the two partitions 13. The spring baffle is "T"-shaped and includes a horizontal baffle 14 and a vertical baffle 15. 5. Fixed connection: The horizontal baffle 14 is slidably engaged with the two partitions 13 and abuts against the interlayer plate 4. The vertical baffle 15 has a through hole 19. The diameter of the through hole 19 is larger than the outer diameter of the spring support column 12 and smaller than the outer diameter of the spring 16. This way, when the vertical baffle 15 is pushed, it can both push the spring 16 to move and avoid the spring support column 12. The spring baffle can move back and forth in the side U-shaped channel under the action of the spring 16, so as to flexibly cover the exposed part of the groove 2 9. At the same time, the cooperation between the spring support column 12, partition 13, horizontal baffle 14, vertical baffle 15 and spring 16 also makes it convenient and quick to adjust the length of the movable end 2 of the safety cover.

[0033] The handle includes a fixed end handle 10 and a movable end handle 11. The fixed end handle 10 is a hollow tube, and the movable end handle 11 is a solid tube. The outer diameter of the movable end handle 11 is smaller than the inner diameter of the fixed end handle 10. One end of the movable end handle 11 is fixedly connected to the movable end cover plate 203, and the other end of the movable end handle 11 can be inserted into one end of the fixed end handle 10. The other end of the fixed end handle 10 is fixedly connected to the fixed end cover plate 103. By adjusting the length of the movable end 2 of the safety cover, the movable end handle 11 can be pulled and retracted in the fixed end handle 10, thereby flexibly adjusting the length of the handle.

[0034] The working principle of this utility model is as follows: When it is necessary to adjust the length of the safety cover, first rotate the bolt 6 so that the interlayer plate 4, the movable end side panel 202 and the fixed end side panel 102 are not in a fixed and tight state. Then, pull the movable end 2 of the safety cover away from or close to the fixed end 1 of the safety cover. At this time, the movable end side panel 202 will be pulled out or pushed out from between the interlayer plate 4 and the fixed end side panel 102, thereby adjusting the length of the exposed part of the movable end side panel 202. The movable end side panel 202 will drive the movable end cover 203 to be pushed in and pulled out. At the same time, the movable end handle 11 will also be pulled out or pushed in from the fixed end handle 10 as the movable end cover 203 is pushed in and pulled out, thereby adjusting the length of the handle. Thus, the length of the entire safety cover can be adjusted according to the actual size of the coupling and the rotating shaft.

[0035] While adjusting the length of the safety cover, slot 2 9 may protrude outwards. When the movable end 2 of the safety cover is pulled outwards, part of slot 2 9 will be exposed. The elastic potential energy of spring 16 will cause the spring baffle to move towards the fixed end cover 103 until the spring baffle abuts against the fixed end cover 103 and stops moving. Thus, the horizontal baffle 14 of the spring baffle will completely cover the exposed part of slot 2 9, thereby preventing rotating objects inside the safety cover from flying out of slot 2 9. At the same time, the cooperation between the spring baffle, the spring support column 12, the partition 13 and the spring 16 makes the adjustment of the entire length of the safety cover convenient and quick.

[0036] When it is necessary to check the working status of the coupling, unfasten the latch 17 and lift the handle upwards. Due to the action of the hinge 18, one side of the fixed end cover 103 and the movable end cover 203 will be lifted upwards. The operator can easily check the working status of the coupling inside the safety cover without having to lift the entire safety cover, thus avoiding contact between the safety cover and the rotating coupling and increasing safety.

[0037] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
