Description

Technical Field

[0001] The utility model relates to the technical field of tooling storage, in particular to a screw pump rotor storage hanger. Background Art

[0002] The single screw pump is a rotor type positive displacement pump, which relies on the meshing of the screw and the bushing to produce volume changes in the suction chamber and the discharge chamber to transport liquid. It is an internally meshed closed screw pump, and the main working parts are composed of a bushing (stator) with a double-headed spiral cavity and a single-headed spiral screw (rotor) meshed with it in the stator cavity. When the input shaft drives the rotor to make planetary rotation around the center of the stator through the universal joint, the stator-rotor pair continuously meshes to form a sealed cavity, and these sealed cavities move axially at a uniform speed without changing the volume, transporting the conveying medium from the suction end to the discharge end through the stator-rotor pair, and the medium sucked into the closed cavity flows through the stator without being stirred or damaged.

[0003] In the existing related technology, since the rotor of the screw pump is a long spiral rod, it is usually stored horizontally for easy storage. The metal screw pump rotor has a large deadweight and will produce slight deformations such as bending when stored horizontally. After the deformed rotor is used to assemble the screw pump, the gap between the rotor and the stator of the screw pump is not controlled, which has a great impact on the conveying efficiency and service life of the screw pump. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a screw pump rotor storage hanger, which solves the problem that the screw pump rotor is deformed due to improper storage, thus affecting the conveying efficiency and service life of the screw pump.

[0005] According to an embodiment of the utility model, a screw pump rotor storage hanger includes a suspended hanger on which a plurality of hooks are evenly distributed and fixed, and a hanging assembly for detachably connecting the end of the screw pump rotor is hung on the hook.

[0006] Through the above technical scheme, when storing the rotor of the screw pump, the rotor is vertically hung on the hanger through the hanging assembly. Since the hanging direction of the rotor and the direction of the gravity it receives are both toward the ground, radial deformation of the rotor can be prevented, ensuring that the shape tolerance of the rotor is within an appropriate range. After the rotor is used to assemble a screw pump, the radial deformation of the rotor can be prevented from affecting the fitting tolerance between the rotor and the stator. At the same time, the possibility of excessive wear of the stator after the rotor is deformed can be prevented, ensuring that the assembled screw pump maintains the designed conveying efficiency and service life.

[0007] Preferably, the hanging assembly includes a fixing piece, in which a stepped through hole is vertically opened, wherein the large hole of the stepped through hole is a light hole for passing the screw pump rotor, and the small hole of the stepped through hole is a threaded hole, in which a hanging ring is connected, and an abutment hole is horizontally opened on one side of the fixing piece, in which an abutment screw is threadedly connected, and the abutment screw is used to abut against the outer wall of the fixed screw pump rotor.

[0008] Through the above technical solution, one end of the screw pump rotor can be conveniently clamped and fixed in the stepped through hole using the hanging assembly, and the rotor can be conveniently disassembled and assembled from the hanger through the lifting ring, making the device more convenient to use.

[0009] Preferably, a fixing nut is threadedly connected to the abutment screw, and the fixing nut is used to tighten the abutment screw.

[0010] Through the above technical solution, the abutment screw can be tightened by using a fixing nut to prevent the abutment screw from loosening and causing the screw pump rotor and the fixing member to separate, thereby improving the stability and practicality of the device.

[0011] Preferably, the hanger is a component of a rectangular structure, and the hanger is made of U-shaped steel, and the opening of the U-shaped steel is arranged toward the top.

[0012] Preferably, the hooks are evenly distributed on both sides of the U-shaped steel.

[0013] Through the above technical scheme, the use of U-shaped steel to make the hanger can increase the structural stability of the hanger. The hooks are fixed on both sides of the U-shaped steel. When heavy objects are hung on the hooks, the U-shaped steel can undergo a certain amount of elastic deformation. When the hanger is subjected to external vibrations, it can play a certain shock-absorbing role and prevent the possibility of collision between adjacent screw pump rotors.

[0014] Preferably, a plurality of supporting feet are provided at the bottom of the hanger, a positioning piece is slidably mounted on the supporting feet, and a plurality of positioning holes for inserting the screw pump rotor are opened on the positioning piece.

[0015] Preferably, an elastic buffer is fixed on the inner wall of the positioning hole.

[0016] Through the above technical solution, the mounted rotor can be positioned by using the positioning member and the buffer member arranged in the positioning hole to prevent the rotor member from colliding. The buffer member can prevent the rotor from colliding with the positioning member and affecting the surface quality of the rotor.

[0017] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0018] 1. When storing the screw pump rotor, use the hanging assembly to hang the rotor vertically on the hanger so that the force it receives is directed toward the ground, reducing the possibility that the rotor will deform due to long-term storage, which will affect its assembly accuracy and thus the conveying efficiency and service life of the assembled screw pump;

[0019] 2. The use of positioning parts and buffer parts can prevent the possibility of collision between adjacent rotors, ensure the surface quality of the rotors, and further improve the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0030] A screw pump rotor storage hanger, reference Figure 1-Figure 4 , including a hanger 1 suspended in the air, on which a plurality of hooks 2 are evenly distributed and fixed, and on the hooks 2 is hung a hanging assembly 3 for detachably connecting the end of a screw pump rotor.

[0031] The hanger 1 is a rectangular structure component, which is made of U-shaped steel by welding. The opening of the U-shaped steel is set toward the top. According to needs, the hanger 1 can be made into other structures such as a circular or "sun" shape.

[0032] The hook 2 is a "J"-shaped component, which can be made by bending round steel or cutting steel plates. The number of hooks 2 is determined according to needs. The hooks 2 and the hanger 1 can be connected by welding. The hooks 2 are evenly distributed on both sides of the U-shaped steel. When the hooks 2 bear a certain weight, the U-shaped steel can undergo a certain amount of elastic deformation.

[0033] The hanging assembly 3 includes a fixing part 31, which is a cylindrical component and can also be made into other structures as needed. A stepped through hole 311 is vertically opened in the fixing part 31, wherein the large hole of the stepped through hole 311 is a light hole for passing the screw pump rotor, and the small hole of the stepped through hole 311 is a threaded hole, in which a hanging ring 32 is connected, and the hanging ring 32 is used to be hung on the hook 2. An abutment hole 312 is horizontally opened on one side of the fixing part 31, and an abutment screw 33 is threadedly connected in the abutment hole 312. The abutment screw 33 can be made of bolts, and the abutment screw 33 is used to abut and fix the outer wall of the screw pump rotor.

[0034] A fixing nut 34 is threadedly connected to the abutting screw 33 , and the fixing nut 34 is used to tighten the abutting screw 33 to prevent the abutting screw 33 from loosening after abutting against the fixed rotor.

[0035] In order to facilitate the placement of the hanger 1, a plurality of supporting feet 11 are vertically arranged at the bottom of the hanger 1. The supporting feet 11 are columnar components, and four supporting feet 11 are arranged here. A positioning member 4 is slidably installed on the supporting feet 11. The positioning member 4 is a flat member, and the positioning member 4 is detachably fixed to the supporting feet 11 by bolts. A plurality of positioning holes 41 for inserting the screw pump rotor are opened on the positioning member 4. An elastic buffer 42 is fixed on the inner wall of the positioning hole 41, and the buffer 42 can be made of elastic rubber. The positioning member 4 and the buffer 42 can prevent the possibility of collision between adjacent rotors and ensure the surface quality of the rotor.

[0036] The implementation principle of a screw pump rotor storage hanger in the present application is:

[0037] Move the positioning member 4 to the bottom of the device, insert one end of the screw pump rotor into the stepped through hole 311 of the fixing member 31, use the tool kit to rotate the abutting screw 33, and after the abutting screw 33 is tightly abutted against the rotor, tighten the fixing nut 34 to prevent the abutting screw 33 from loosening; install the lifting ring 32 in the other end of the stepped through hole 311, and hang the lifting ring 32 connected with the positioning member 4 on the hook 2. Similarly, hang the lifting ring 32 on all the hooks 2, and then move the positioning member 4 to the middle of the supporting foot 11, so that the end of the rotor away from the fixing member 31 is inserted into the positioning hole 41. The device is used to hoist and store the rotor of the screw pump, so that the force received by the rotor and the direction of its storage are both toward the ground, which can prevent the rotor from radial deformation and reduce the possibility that the rotor will be deformed due to long-term storage, which will affect its assembly accuracy and thus affect the conveying efficiency and service life of the assembled screw pump.
