Technical Field

[0001] This utility model relates to the field of rail replacement and maintenance technology for hot-dip galvanized circular tracks, and particularly to a rail replacement and maintenance device for hot-dip galvanized circular tracks. Background Technology

[0002] Hot-dip galvanizing is a widely used metal corrosion protection method, with extensive applications in numerous fields such as construction, machinery manufacturing, and power and electrical engineering. In the hot-dip galvanizing production process, a circular track is a crucial conveying and operating path. Galvanizing hoists and other equipment run along this track to complete the lifting of workpieces and various process steps.

[0003] With the development of the hot-dip galvanizing industry, the requirements for production efficiency and product quality are constantly increasing. When some or a single electric hoist needs to be repaired or replaced during long-term operation, the entire circular track needs to be stopped, so the electric hoists will stop working, which seriously affects production efficiency. Therefore, a track replacement and maintenance device for hot-dip galvanized circular tracks is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a rail replacement and maintenance device for hot-dip galvanized circular tracks to solve the aforementioned problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A rail replacement and maintenance device for hot-dip galvanized circular rails, comprising:

[0007] A fixed beam, which is a circular track; a movable beam track, fixedly mounted on the top of the fixed beam; a movable trolley, slidably mounted on the movable beam track, the movable trolley including a first movable beam and a second movable beam arranged laterally, with wheels fixedly mounted at both ends of the first and second movable beams, and a first motor for driving the wheels fixedly mounted at both ends of the second movable beam, and an electric hoist suspended at the bottom ends of the first or second movable beam; a limit switch, which includes a pin fixedly mounted on the top of the fixed beam and electric locking pins fixedly mounted at both ends of the first and second movable beams.

[0008] Furthermore, the fixed beam has a notch at a position corresponding to the moving vehicle.

[0009] Furthermore, the traveling wheels are slidably mounted on the moving beam track.

[0010] Furthermore, there are two pins, and each pin has a slot on its side near the mobile vehicle. The slot is flared.

[0011] Furthermore, the electric locking pin includes connecting blocks fixedly disposed at both ends of the first moving beam and the second moving beam, and a locking rod slidably disposed inside the connecting blocks, wherein a roller is rotatably disposed on the outer ring of the locking rod near the locking groove.

[0012] Furthermore, a second motor is fixedly installed on the electric hoist.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model describes a track replacement and maintenance device for hot-dip galvanized circular tracks. Through a combined design of a moving beam track and a moving trolley, the moving trolley moves directionally on the moving beam, switching between the first and second moving beams at the notch in the fixed beam. The electric hoist requiring repair or replacement of its second motor is stopped on the moving beam of the moving trolley connected to the fixed beam. A normally functioning electric hoist is installed on the other moving beam of the moving trolley. The forward and backward movement of the moving trolley replaces the electric hoist requiring repair or replacement of its second motor on the fixed beam. This ensures that other electric hoists on the fixed beam track can replace the electric hoist requiring repair or replacement of its second motor without stopping operation. Limit switches ensure the accuracy and stability of the connection between the moving trolley and the fixed beam. Attached Figure Description

Furthermore, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] This embodiment relates to a rail replacement and maintenance device for hot-dip galvanized circular rails. In terms of overall structure, as follows... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a fixed beam 1, a moving beam track 2, a moving vehicle 3, and a limit switch 4.

[0026] The fixed beam 1 is a ring track, the movable beam track 2 is fixedly installed on the top of the fixed beam 1, and the movable vehicle 3 is slidably installed on the movable beam track 2. The movable vehicle 3 includes a first movable beam 301 and a second movable beam 302 arranged laterally. The first movable beam 301 and the second movable beam 302 are fixedly provided with walking wheels 303 at both ends. The second movable beam 302 is fixedly provided with a first motor 304 that drives the walking wheels 303 at both ends. An electric hoist 305 is hoisted at the bottom ends of the first movable beam 301 or the second movable beam 302. The limit switch 4 includes a pin head 401 fixedly installed on the top of the fixed beam 1 and an electric locking pin 402 fixedly installed at both ends of the first movable beam 301 and the second movable beam 302.

[0027] It is worth mentioning that the fixed beam 1 is a circular track used for mounting the electric hoist 305 and for moving the electric hoist 305. There are two moving beam tracks 2, which are longitudinally fixedly installed on the top of the fixed beam 1, and their ends are respectively fixedly installed on the transversely arranged support beams. The support beams are fixedly installed to provide support for the installation of the moving beam tracks 2. The moving beam tracks 2 are used for the sliding installation of the moving vehicle 3. The first moving beam 301 and the second moving beam 302 are transversely fixedly installed at the front and rear ends of the bottom of the moving vehicle 3. There are four traveling wheels 303, which are symmetrically installed at the ends of the first moving beam 301 and the second moving beam 302 for the forward and backward movement of the moving vehicle 3. There are two first motors 304, which are installed at the ends of the second moving beam 302 and respectively connected to the second moving beam 305. The traveling wheels 303 on the moving beam 302 are connected to provide power for the rotation of the traveling wheels 303. The normally used electric hoist 305 is installed on the moving beam of the moving vehicle 3, which does not form a complete track with the fixed beam 1. It is used to replace the electric hoist 305 on the fixed beam 1 that needs to be repaired or replaced. The limit switch 4 consists of a pin 401 and an electric locking pin 402. The pin 401 is fixedly installed on the fixed beam 1. The electric locking pin 402 is fixedly installed at both ends of the first moving beam 301 and the second moving beam 302. It is used to engage with the pin 401 to fix the moving vehicle 3. Limit sensors are fixedly installed on both ends of the first moving beam 301 and the second moving beam 302 to control the distance when the moving vehicle 3 moves forward and backward.

[0028] As a preferred option, it remains as follows Figure 1 and Figure 4 As shown in this embodiment, the fixed beam 1 has a notch at the position corresponding to the moving vehicle 3.

[0029] It should be noted that the length of the notch on the fixed beam 1 is equal to that of the first moving beam 301 and the second moving beam 302 on the moving vehicle 3, and the material and shape of the fixed beam 1 are the same as those of the first moving beam 301 and the second moving beam 302. The notch on the fixed beam 1 is filled by the first moving beam 301 or the second moving beam 302, so that the fixed beam 1 forms a closed circular track.

[0030] As a preferred option, it remains as follows Figure 1 and Figure 4 As shown, in this embodiment, the traveling wheel 303 is slidably mounted on the moving beam track 2.

[0031] Specifically, the traveling wheel 303 is installed on the moving beam track 2, enabling the traveling wheel 303 to move back and forth on the moving beam track 2.

[0032] As a preferred option, it remains as follows Figure 1 , Figure 4 and Figure 5As shown, there are two pins. The pin 401 has a slot 4011 on the side near the moving vehicle 3. The slot 4011 is flared.

[0033] Specifically, the two pins 401 are located on the top of the fixed beam 1 on both sides of the notch of the fixed beam 1, and are used to fix the moving vehicle 3. The slot 4011 is flared and is opened on the side of the pin 401. This avoids the problem that the limit switch 4 cannot be locked due to a small deviation after the moving vehicle 3 has been moved and stopped, and improves the locking success rate of the limit switch 4.

[0034] As a preferred option, such as Figure 5 As shown, in this embodiment, the electric locking pin 402 includes a connecting block 4021 fixedly disposed at both ends of the first moving beam 301 and the second moving beam 302, and a locking rod 4022 slidably disposed inside the connecting block 4021. A roller 4023 is rotatably disposed on the outer ring of the locking rod 4022 near the locking groove 4011.

[0035] Specifically, there are four connecting blocks 4021, which are fixedly installed at both ends of the first moving beam 301 and the second moving beam 302 respectively. A cylindrical groove is opened on the side of the connecting block 4021 near the slot 4011 for sliding installation of the locking rod 4022. The locking rod 4022 is cylindrical, and the diameter of the end near the slot 4011 is smaller than the diameter of the end away from the slot 4011. The end of the locking rod 4022 with a smaller diameter has grooves evenly spaced around its circumference. The rollers 4023 are slidably installed on the grooves at equal intervals to reduce the wear between the locking rod 4022 and the slot 4011.

[0036] As a preferred option, it remains as follows Figure 3 and Figure 4 As shown in this embodiment, a second motor 306 is fixedly installed on the electric hoist 305.

[0037] Specifically, each electric hoist 305 is equipped with a second motor 306, which provides power for the electric hoist 305 to move on the circular track.

[0038] The central control system controls the movement of each electric hoist 305 and the moving cart 3. When the second motor 306 on the electric hoist 305 needs to be repaired or replaced, if the first moving beam 301 and the fixed beam 1 form a closed loop, a good electric hoist 305 is installed on the second moving beam 302, and the number of electric hoists 305 is the same as the number of electric hoists 305 to be repaired or replaced. After the electric hoists 305 to be repaired or replaced move onto the first moving beam 301, they stop moving. The moving cart 3 moves backward under the power drive of the first motor 304, so that the second moving beam 302 and the fixed beam 1 form a closed loop. At this time, the newly installed electric hoist 305 on the second moving beam 302 starts to work, and the second motor 306 on the first moving beam 301 can be replaced or repaired at the same time.

[0039] Similarly, if the second moving beam 302 and the fixed beam 1 form a closed loop track, a good electric hoist 305 is installed on the first moving beam 301, and the number of electric hoists 305 is the same as the number of electric hoists 305 to be repaired or replaced. After the electric hoists 305 to be repaired or replaced are moved onto the second moving beam 302, they stop moving. The moving car 3 moves backward under the power drive of the first motor 304, so that the first moving beam 301 and the fixed beam 1 form a closed loop track. At this time, the newly installed electric hoist 305 on the first moving beam 301 starts to work, and at the same time, the second motor 306 on the second moving beam 302 can be replaced or repaired.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
