Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace metallurgical equipment, in particular to an encoder mounting bracket for a blast furnace hoist motor. Background Art

[0002] With the improvement of equipment automation level and the demand for intelligence, the metallurgical industry has higher and higher requirements for the accuracy and continuity of encoder data. The installation of the encoder requires a bracket. The quality of the encoder installation directly determines the measurement accuracy of the encoder. An unreasonable connection method will affect the accuracy of the encoder feedback signal and even affect the service life of the encoder. Therefore, as a precision device for accurately measuring and feedbacking the running speed, the installation connection method between the encoder and the motor is crucial. Summary of the Utility Model

[0003] The utility model provides an encoder mounting bracket for a blast furnace hoist motor to solve the problems in the above background.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] An encoder mounting bracket for a blast furnace hoist motor includes an encoder base. An encoder shaft seat is sleeved inside the encoder base. An elastic coupling is vertically arranged on the top of the encoder shaft seat, and the elastic coupling penetrates through the encoder base and is connected with an encoder.

[0006] Further, a base flange is arranged at the bottom of the encoder base. Support legs are arranged on the top of the base flange, and an encoder mounting bottom plate is connected to the top of the support legs.

[0007] Further, encoder mounting holes are formed in the encoder mounting bottom plate, and encoder counterbore grooves are formed on the outer edges of the top sides of the encoder mounting holes.

[0008] Further, a shaft seat bottom plate is arranged at the bottom of the encoder shaft seat. A plurality of shaft seat positioning holes are formed on the outer edges of the top of the shaft seat bottom plate. A first shaft seat connecting shaft is vertically arranged on the shaft seat bottom plate. A second shaft seat connecting shaft is connected to the top of the first shaft seat connecting shaft, and a flat fixing groove is formed on the side of the second shaft seat connecting shaft.

[0009] The utility model has the following beneficial effects:

[0010] The utility model provides a blast furnace hoisting motor encoder mounting bracket, which mainly comprises three parts: an encoder base, an elastic coupling and an encoder shaft seat. The encoder in the mounting bracket is mounted on the encoder base, and the encoder base is fixedly mounted on the rear end cover of the motor by bolts. The encoder shaft seat is fixed to the motor shaft by fastening bolts, and the encoder shaft and the encoder shaft seat are connected in series by an elastic coupling. When the motor is running, the encoder is driven to rotate synchronously, and the running speed of the motor is accurately measured and fed back. The difficulty in installing the blast furnace hoisting motor encoder is greatly solved, and the encoder frequently breaks the shaft and other faults, thereby improving the installation accuracy and operation stability of the encoder, and solving the problem that in the current metallurgical equipment encoder installation process, the safety, rationality and stability of the encoder are usually poor due to the lack of special encoder installation tooling, which ultimately has a great impact on the accuracy and service life of the encoder feedback signal.

[0011] In the utility model, the encoder and the encoder bracket are seamlessly fitted and fixed, ensuring that the encoder as a whole has no jitter during the transmission process; the application of the elastic coupling increases the buffer on the basis of ensuring the transmission strength, thereby reducing the damage probability of the encoder as much as possible; the precise encoder installation bracket absorbs the concentricity between the shafts generated during the installation process to a large extent; holes are opened on both sides of the encoder bracket to facilitate observation of the operating conditions of the elastic coupling and the motor shaft seat; after the encoder bracket is installed, it does not require maintenance and is extremely easy to install. The design of the holes on both sides provides convenience for the replacement of the encoder in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] As Figures 1-4 shown, a mounting bracket for a blast furnace hoist motor encoder includes an encoder base 102, an encoder shaft seat 104 is sleeved inside the encoder base 102, an elastic coupling 103 is vertically arranged at the top of the encoder shaft seat 104, and the elastic coupling 103 passes through the encoder base 102 and is connected to an encoder 101.

[0020] A base flange 105 is arranged at the bottom of the encoder base 102, a support leg 111 is arranged at the top of the base flange 105, and an encoder mounting bottom plate 110 is connected to the top of the support leg 111.

[0021] Encoder mounting holes 107 are formed in the encoder mounting bottom plate 110, and encoder counterbore grooves 108 are formed in the outer edge of the top side of the encoder mounting holes 107.

[0022] A shaft seat bottom plate 112 is arranged at the bottom of the encoder shaft seat 104, a plurality of shaft seat positioning holes 113 are formed in the outer edge of the top of the shaft seat bottom plate 112, a first shaft seat connecting shaft 115 is vertically arranged on the shaft seat bottom plate 112, a second shaft seat connecting shaft 116 is connected to the top of the first shaft seat connecting shaft 115, and a flat fixing groove 117 is formed in the side of the second shaft seat connecting shaft 116.

[0023] When the utility model is specifically applied, first, it is necessary to determine that there is an installation space for the motor end cover and the motor rotating tail shaft. The motor rear end cover needs to be processed with threaded holes for fixing the encoder base, and the motor tail shaft needs to be processed with threaded holes for fixing the encoder shaft seat. When installing the encoder shaft seat 104, pass the bolt through the seat fixing hole 114, and use the seat positioning hole 113 to adjust the installation accuracy. Fix the encoder shaft seat 104 on the motor tail shaft to ensure that the encoder shaft seat 104 and the motor rotating shaft are on the same center line. When installing the encoder 101, use bolts to fix the encoder 101 on the encoder installation base plate 110 by using the encoder threaded fixing hole 109, so that the encoder 101 and the encoder base 102 are seamlessly fitted. When installing the encoder base 102, the base flange 105 and the motor rear end cover are seamlessly fitted, and 4 fastening bolts are fixedly connected to the motor rear end cover by using the base flange installation holes 106. When installing the elastic coupling 103, first install one side of the encoder 101, compress the elastic coupling 103, and install the other side of the coupling on the second shaft seat connecting shaft 116 of the encoder shaft seat 104. Use the coupling fastening screw to firmly fix the elastic coupling 103. When fixing the elastic coupling 103 on the second shaft seat connecting shaft 116, the coupling fastening screw is fastened at the plane fixing groove 117 to prevent sliding during operation, effectively ensuring the measurement accuracy of the encoder 101. Then, connect the encoder 101, the elastic coupling 103, and the encoder shaft seat 104 in series. At least 5 mm of allowance should be left at both ends of the shaft of the elastic coupling 103 and the encoder 101 and the second shaft seat connecting shaft 116 of the encoder shaft seat 104 to facilitate later adjustment and replacement and disassembly of the elastic coupling 103. The installation method of the entire encoder 101 provides great convenience for its replacement. The application of the elastic coupling 103 and the matching use of the encoder base 102 and the motor shaft seat ensure the concentricity between shafts, greatly reducing the problem that the coupling and the encoder 101 are often damaged. Therefore, this installation bracket has good practicability.
