Description

Technical Field

[0001] The utility model relates to the technical field of machine pump maintenance, in particular to an anti-reverse automatic disengagement winch. Background Art

[0002] A pump is a device commonly used in the petrochemical industry to transport liquid media. Usually, there are two pumps, one in operation and one in standby. In order to avoid rust and corrosion of the bearings and bending of the pump shaft caused by long-term out-of-service of the pump, it is necessary to regularly immerse the pump in oil to prevent rust and corrosion of the bearings. At the same time, the pump needs to be cranked before starting to confirm whether the pump shaft is locked. However, since the motors and pump shafts of large and medium-sized pumps are relatively heavy, manual cranking is very laborious, so it is often necessary to use a cranking device to crank them.

[0003] Chinese patent publication number CN219380577U discloses a machine pump winch, including a handle, a connecting rod structure and a locking structure; one end of the handle is set as a hand-holding end, and the other end is set as a locking end; the connecting rod structure is fixedly connected to the locking end, and a position adjustment member is provided on the connecting rod structure; the locking structure is provided with a first locking member and a second locking member, and the first locking member and the second locking member are spaced apart and are perpendicular to the axial direction of the connecting rod structure, and the first locking member is fixedly connected to the connecting rod structure, and the second locking member is movably arranged on the connecting rod structure and is limited in position by the position adjustment member. The utility model has a simple structure and a reasonable design. When in use, the nuts on both sides of the machine pump coupling can be clamped by the first locking member and the second locking member, so that the winch is not easy to slip during the force application process, and the use process is safer. At the same time, the distance between the first locking member and the second locking member is adjustable, which can meet the winching requirements of machine pumps with different coupling widths and has a wide range of applications.

[0004] However, the pump winch has significant limitations in use. It can currently only locate the intersection of two pipes at a specific location, and the winch is fixedly installed. During the winch operation, if part of the pump loses control due to inertia, due to design limitations, it is difficult for the operator to disengage from the tool handle in time, which greatly increases the danger during the operation.

[0005] This requires the design of a special turning tool so that when the turning is uncontrollable, the tool handle can be disengaged to avoid injury. Utility Model Content

[0006] In response to the above problems, an anti-reversal automatic disengagement winch is provided. The length of the chain is adjusted according to the specifications of the pipe. When the chain is adjusted to the appropriate position, the U-shaped plate is moved to make the U-shaped plate contact the chain, so that the chain can be positioned, and the winch main board can be installed stably. Then the first V-shaped plate is connected by an insert rod, and the first V-shaped plate is matched with the second V-shaped plate. When the first V-shaped plate is reversed under the action of the insert rod and the coil, the second V-shaped plate is engaged with the positioning column on the top of the first V-shaped plate, which can prevent the machine pump from reversing and has higher safety.

[0023] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Please refer to Figures 1 to 6, an anti-reverse automatic disengagement barring device, comprising a barring main board 1, a first rack 2, a chain 3, a U-shaped plate 4, an insertion rod 5, a first V-shaped plate 6, a positioning column 7 and a second V-shaped plate 8. The first rack 2 is arranged at the top of the barring main board 1, the chain 3 is arranged on the outside of the first rack 2, the U-shaped plate 4 is arranged above the barring main board 1, the insertion rod 5 is arranged at one end of the barring main board 1, the first V-shaped plate 6 is arranged to move the insertion rod 5, the positioning column 7 is arranged on the top of the first V-shaped plate 6, and the second V-shaped plate 8 is arranged on the top of the first V-shaped plate 6.

[0025] The first rack 2 is positioned through the turntable mainboard 1, and then the length of the chain 3 is adjusted according to the pipe specifications. When the chain 3 is adjusted to a suitable position, the U-shaped plate 4 is moved to make the U-shaped plate 4 contact with the chain 3, so that the chain 3 can be positioned, and the turntable mainboard 1 can be stably installed. Then, the first V-shaped plate 6 is connected through the insertion rod 5, and the first V-shaped plate 6 is matched with the second V-shaped plate 8. When the first V-shaped plate 6 is reversed under the action of the insertion rod 5 and the coil, the second V-shaped plate 8 is engaged with the positioning column 7 on the top of the first V-shaped plate 6, thereby avoiding the reversal phenomenon, thereby improving the safety performance of the product.

[0026] like Figure 1 and Figure 4 As shown, the first rack 2 is engaged with the chain 3, and first limiting grooves are symmetrically opened above both sides of the turntable main board 1. The first limiting groove has a first limiting plate 19 connected to the U-shaped plate 4 slidingly installed inside. Both sides of the U-shaped plate 4 are threadedly connected with first bolts 9 for positioning.

[0027] Move the chain 3 to engage the first rack 2 with the chain 3, and then move the first limit plate 19 under the action of the first limit slide. When the first limit plate 19 moves, it drives the U-shaped plate 4 to rise and fall. When the U-shaped plate 4 contacts the upper surface of the chain 3, rotate the first bolt 9 so that the first bolt 9 passes through the U-shaped plate 4 and contacts the turntable main board 1, thereby realizing the positioning of the U-shaped plate 4 and making the chain 3 more stably installed.

[0028] like Figure 1 and Figure 5 As shown, a second rack is provided at the bottom of the turntable main board 1, and the second rack matches the chain 3. Second limiting grooves are symmetrically opened below both sides of the turntable main board 1, and a second limiting plate 10 is slidably installed inside the second limiting groove.

[0029] The second rack is positioned through the turntable main board 1, and then the second rack is engaged and installed with the chain 3, and the second limit plate 10 is moved under the action of the second limit slide groove. The second limit plate 10 adjusts the height of the C-shaped card plate 11 when moving. When the C-shaped card plate 11 is in contact with the chain 3, the second bolt is rotated so that the second bolt passes through the C-shaped card plate 11 and contacts with the turntable main board 1, thereby fixing the chain 3.

[0030] like Figure 1 and Figure 4 As shown, a plurality of positioning holes are formed at equal intervals inside the insertion rod 5 , a hollow cylinder 12 is sleeved on one end of the insertion rod 5 , and a screw rod 13 matching the positioning holes is provided inside the hollow cylinder 12 .
