Description

Technical Field

[0001] The invention relates to the technical field of equipment adjustment, and in particular to an assembly method of a center slip ring fork. Background Art

[0002] Nowadays, due to different designs and operational requirements, equipment of varying sizes and specifications is required. Furthermore, coordination between these equipment is required, and different equipment must be adjusted to different heights or angles, as well as transmission, to achieve the design and production objectives. For example, a rotary platform is mounted on a base, and a slip ring is an electrical component responsible for connecting the rotating body and transmitting energy and signals. Slip rings are typically installed at the center of rotation of the equipment and primarily consist of two main parts: a rotating part and a stationary part. The rotating part connects to the rotating structure of the equipment and rotates with it, and is called the "rotor." The stationary part connects to the fixed structure of the equipment and provides energy, and is called the "stator."

[0003] For cranes, in order to transmit electricity and signals better and more reliably, slip rings are installed between the base of the crane and the slewing platform. The rotor of the slip ring of a traditional crane is installed on the slewing platform, and the stator is installed on the base. When the slewing platform rotates, the rotor of the slip ring rotates. However, due to different crane models, or different requirements for the position of the slip ring for cranes of the same model, the installation position and space of the slip ring are limited, which brings inconvenience to the installation of the slip ring. For example, the Chinese patent application number is CN202220686646.X, and the announcement date is 2022.07.29. It discloses a high-efficiency fixed platform for frame welding, including a platform, the outer surface of the lower end of the platform is provided with a transmission mechanism and a stabilizing component, and the stabilizing component is located at the transmission mechanism. On the outside of the structure, the transmission mechanism includes a base, a gear box, a handwheel, a connecting rod, a first bevel gear, a second bevel gear, a supporting transmission rod, a main gear, a gear ring, and an auxiliary gear, and the stabilizing component includes a slip ring, a rotating bead, a support rod, and a slide. This utility model is aimed at different positions of the frame to be welded. When it needs to be adjusted, the staff turns the handwheel, and the handwheel drives the first bevel gear to rotate on the inner wall of the gear box through the connecting rod. The second bevel gear drives the main gear to rotate between the three auxiliary gears based on the first bevel gear through the supporting transmission rod. At the same time, the gear ring rotates synchronously based on the three auxiliary gears to achieve the rotation adjustment of the platform, which brings better use effect. However, for different crane models, or different requirements for the position of the slip ring for cranes of the same model, the installation position and space of the slip ring will be limited, and the operation is inconvenient and the assembly is complicated. Summary of the Invention

[0004] The present invention aims to provide an assembly method for a center slip ring fork, which is convenient for assembly and can facilitate and flexibly install the slip ring when different equipment is running.

[0005] To achieve the above-mentioned purpose, a method for assembling a center slip ring fork is provided, comprising an upper fork portion for connecting a rotary platform and a lower fork portion for connecting a slip ring, the upper fork portion comprising a connecting plate, a first hollow steel, and a wire code, the lower fork portion comprising a second hollow steel and a channel steel, the connecting plate being provided with bolt holes, the connecting plate being connected to equipment via bolts, the first hollow steel being fixedly mounted on the connecting plate, the channel steel being provided with slotted holes, the second hollow steel being fixedly mounted on the channel steel, the channel steel being connected to other equipment via the slotted holes, and the second hollow steel being nested in the first hollow steel;

[0006] The specific steps of the center slip ring fork assembly method include:

[0007] (1) According to the needs of the fluctuation adjustment distance between the slewing platform and the slip ring in different crane models or the same crane model, the center slip ring fork with a hollow steel sliding distance greater than the fluctuation adjustment distance between the slewing platform and the slip ring is selected;

[0008] (2) Fix the channel steel on the rotor of the slip ring; and fix the stator of the slip ring on the base; the rotor and stator are connected in rotation;

[0009] (3) Fix the connecting plate on the rotary platform;

[0010] (4) Insert the first hollow steel on the upper part of the fork into the second hollow steel on the lower part of the fork, and after assembly, the hollow steels can slide relative to each other;

[0011] (5) Fix the wire code on the first hollow steel on the upper part of the fork.

[0012] With the above arrangement, when the slewing platform is connected to the upper part of the fork, bolt holes are provided on the connecting plate, and the connecting plate is connected to the equipment by bolts; slots are provided on the channel steel, so that the slip ring is connected to the channel steel through the slots; the first hollow steel is inserted into the first hollow steel, so that two different equipment can adapt to different models or different distances of the same model of crane slip rings relative to the slewing platform during operation. The installation of the slip ring is convenient and flexible. At the same time, the assembly method only requires the slewing platform and the slip ring to be fixed to the connecting plate of the upper part of the fork and the channel steel of the lower part of the fork respectively, and then the slip ring is fixed to the base and then the first hollow steel is inserted into the second hollow steel for assembly to achieve the required operating effect of the equipment, and the assembly is convenient.

[0013] Furthermore, the connecting plate is provided with two or more bolt holes, the lower surface of the connecting plate is fixedly connected to one end of the first hollow steel, and the first hollow steel is provided with a wire code, and the wire code is provided on the outer surface of the first hollow steel;

[0014] Step (2) specifically includes fixing the slewing platform and the connecting plate with bolts;

[0015] Step (5) specifically includes fixing the wire code on the outer surface of the first hollow steel of the upper part of the fork by bolts.

[0016] The above arrangement is to fix the connecting plate to the first hollow steel so that the connecting plate on the upper part of the fork can be connected to the equipment by bolts. By setting a wire code on the outer surface of the first hollow steel, it is easy to take and disassemble the fork.

[0017] Furthermore, the upper surface of the channel steel is fixedly connected to one end of the second hollow steel, and a slotted hole is provided at the bottom of the channel steel;

[0018] Step (3) specifically includes clamping and installing the slip ring and the channel steel through the slot hole set at the bottom end of the channel steel, thereby completing the assembly connection between the lower part of the fork and the slip ring.

[0019] The above arrangement is fixedly connected to the second hollow steel through the channel steel, so that the lower part of the shift fork can be connected to the slip ring through the slotted hole provided at the bottom of the channel steel.

[0020] Furthermore, the cross-sectional shapes of the first hollow steel and the second hollow steel are set to be square, and the outer surface of the other end of the first hollow steel is inserted into the inner surface of the other end of the second hollow steel; step (4) specifically includes aligning the first hollow steel and the second hollow steel according to the cross-sectional shapes and then inserting them.

[0021] The above setting, by setting the cross-sectional shape of the first hollow steel and the second hollow steel to be square, can enable one device to drive another device for transmission during operation; by setting the first hollow steel to be inserted into the second hollow steel, when different devices are running, the torque between the rotary platform and the slip ring is transmitted through the fork.

[0022] Furthermore, the cross-sectional area of ​​the inner ring of the second hollow steel is greater than the cross-sectional area of ​​the outer ring of the first hollow steel.

[0023] The above arrangement conveniently enables the first hollow steel to be inserted into the second hollow steel.

[0024] Furthermore, the sliding distance between the second hollow steel and the first hollow steel is greater than the fluctuation adjustment distance between the devices having a defined distance;

[0025] The above setting, by setting the sliding distance of the hollow steel to be greater than the fluctuation adjustment distance between the devices, can ensure that the second hollow steel will not slip when the second hollow steel is nested in the first hollow steel for sliding, thereby preventing the normal operation of the equipment from being affected.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings and specific implementation plans.

[0035] like Figure 1-6As shown, an embodiment of the present invention provides an assembly method of a center slip ring fork, which is used to connect the upper part of the fork of one device and the lower part of the fork of another device. When one device is connected to the upper part of the fork, the other device is connected to the lower part of the fork. In this embodiment, one device is a rotary platform and the other device is a slip ring. The structures of the rotary platform and the slip ring are prior art and will not be repeated here. The upper part of the shift fork includes a connecting plate 1, a first hollow steel 2 and a wire code 5, and the lower part of the shift fork includes a second hollow steel 3 and a channel steel 4. A first bolt hole 11 and a second bolt hole 12 are provided on the connecting plate 1, and the first bolt hole 11 and the second bolt hole 12 are respectively provided on both sides of the connecting plate 1. The first bolt hole 11 and the second bolt hole 12 are provided on both sides of the connecting plate 1, and the connecting plate 1 can be connected to the equipment by bolts; one end of the first hollow steel 2 is fixedly mounted on the lower surface of the connecting plate 1, so that the connecting plate 1 of the upper part of the shift fork can be connected to the rotary platform by bolts, and a wire code 5 is provided on the left side of the outer surface 6 of the first hollow steel to facilitate the removal of the shift fork; one end of the second hollow steel 3 is fixedly mounted on the upper surface of the channel steel 4, and the bottom end surface of the channel steel 4 is provided with a first slotted hole 41 and a second slotted hole 42, which are connected through the bottom end of the channel steel 4 The first slotted hole 41 and the second slotted hole 42 on the surface can be engaged with the protrusions of other equipment; the cross-sectional shape of the first hollow steel 2 and the second hollow steel 3 is set to be square, which can enable one device to drive the other device for transmission during operation, and the inner surface of the other end of the first hollow steel 2 is inserted into the outer surface of the second hollow steel 3. Since the distance between the slewing platform and the slip ring of a crane of one model is limited, if for another model of crane, there is a slight difference between the slewing platform and the slip ring relative to the one model, the first hollow steel 2 and the second hollow steel 3 can slide relative to each other by installing the crane of the other model through the fork, and then the slip ring can be installed between cranes of different models by fine-tuning through the fork. For cranes of the same model, different position requirements for the slip ring and the slewing platform can also be adjusted by the fork.

[0036] The sliding distance between the second hollow steel and the first hollow steel is greater than the fluctuation adjustment distance between the devices with a limited distance. If the fluctuation adjustment distance between one device and another is 10 meters, the fluctuation adjustment distance is the difference in distance between the slewing platform and the slip ring between different crane models, or the difference in distance between the slewing platform and the slip ring of the same crane model. In this case, the hollow steel sliding distance is greater than 10 meters.

[0037] In this embodiment, if Figure 7 As shown, the assembly method of the above-mentioned center slip ring fork specifically includes the following steps:

[0038] (1) According to the needs of the fluctuation adjustment distance between the slewing platform and the slip ring in different crane models or the same crane model, the center slip ring fork with a hollow steel sliding distance greater than the fluctuation adjustment distance between the slewing platform and the slip ring is selected;

[0039] (2) Fix the channel steel on the rotor of the slip ring; and fix the stator of the slip ring on the base; the rotor and stator are connected in rotation;

[0040] (3) Fix the connecting plate on the rotary platform;

[0041] (4) Insert the first hollow steel on the upper part of the fork into the second hollow steel on the lower part of the fork, and after assembly, the hollow steels can slide relative to each other;

[0042] (5) The wire code is fixed on the outer surface of the first hollow steel of the upper part of the fork by bolts.
