Description

Technical Field

[0001] This invention belongs to the field of linear motor technology, and specifically relates to a linear motor connecting cable fixing device and installation method. Background Technology

[0002] Currently, there are generally three ways to connect long stator modules of linear motors in series: 1) Pre-reserved winding leads, which are then bent and welded together on-site, with the exposed parts finally insulated; 2) Pre-formed busbar method. The connecting busbar is pre-formed in the factory, and the non-joint parts are insulated. On-site, both ends of the pre-formed busbar are connected to the leads of the two adjacent modules, and the joints are then insulated; 3) Cable connection method. Cables are welded on-site, and the cable joints are then insulated.

[0003] Currently, the connection wires between modules are primarily fixed using wire clamps. This requires pre-drilling bolt holes at the fixing points, and then using the clamp's base plate, cover plate, and tightening bolts to secure the leads. This method is advantageous for applications with a relatively small number of phases, where the leads to be fixed are regularly shaped and their positions are clearly defined. However, when the linear motor has a large number of phases, the connections between modules need to be twisted or misaligned in space. To achieve this, the wire clamps require a more specialized shape and must be strung together in layers, resulting in a larger installation space, inefficient installation, and higher costs. Summary of the Invention

[0004] In order to solve the above-mentioned problems in the prior art, the purpose of this invention is to provide a linear motor connecting cable fixing device and installation method.

[0005] The technical solution adopted in this invention is as follows: A linear motor connecting cable fixing device includes a first fixing device, a second fixing device, and a third fixing device respectively mounted on a bracket on the long stator of the linear motor.

[0006] The present invention provides a linear motor long stator mounting bracket with a first fixing device, a second fixing device, and a third fixing device installed at specific positions. These devices secure the power input cables to the linear motor long stator, the connecting cables on both sides of the long stator air gap, and the series cables between long stator modules on the same side. The invention provides targeted fixing devices based on the specific cable fixing requirements at specific locations, allowing for orderly arrangement and binding of cables, preventing cable clutter, facilitating the fixing operation, and enabling rapid cable fixation.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the invention can be combined with each other.

[0021] like Figures 1-6 As shown, the linear motor connecting cable fixing device of this embodiment includes a first fixing device 1, a second fixing device 2 and a third fixing device 3 respectively installed on the mounting bracket 4 on the long stator 5 of the linear motor. The first fixing device 1 is used to fix the connecting cable 6 for power input to the long stator 5 of the linear motor. The second fixing device 2 is used to fix the connecting cables 6 on both sides of the air gap of the long stator. The third fixing device 3 is used to fix the series cables 6 between the long stator modules on the same side.

[0022] The present invention provides a first fixing device 1, a second fixing device 2, and a third fixing device 3 installed at specific positions on the mounting bracket 4 for the linear motor long stator 5. This allows for the fixing of the connecting cables 6 for power input to the linear motor long stator 5, the connecting cables 6 on both sides of the long stator air gap, and the series cables 6 between modules on the same side of the long stator. The present invention provides targeted fixing devices based on the specific needs of fixing the cables 6 at specific positions, enabling the cables 6 to be arranged and bound in an orderly manner, avoiding cable clutter, making the fixing operation more convenient, and achieving rapid cable fixing.

[0023] Specifically, such as Figures 7-10 As shown, the first fixing device 1 includes two crossbeams 11 connected to the mounting bracket 4. The connecting cable 6 for power input to the linear motor stator 5 is fixed to the crossbeams 11 by the first binding strap 12. A support plate 13 is connected between the two crossbeams 11.

[0024] The bridging beam 11 includes a linear support section 111, with vertical connecting sections 112 on both sides of the linear support section 111. The vertical connecting sections 112 are connected to the mounting bracket 4. Several cables 6 are arranged in two layers on the same side of the linear support section 111. The connecting cables 6 that supply power to the linear motor stator 5 can be orderly tied on the two bridging beams 11, achieving rapid and orderly fixation of the cables 6 at this location.

[0025] The first fixing device 1 is used to fix the cable 6 leading onto the long stator 5 of the linear motor, and mainly consists of a bridging beam 11, a support plate 13, a nut, and a first binding strap 12. The bridging beam 11 is made of round steel bent into a C-shape, with threads machined at both ends to facilitate the connection and fixation of the first fixing device 1 to the mounting bracket 4. Each set of first fixing devices 1 consists of two bridging beams 11. The support plate 13 is formed by cutting steel plate, and four sets of bridging beam mounting holes are machined on the support plate 13.

[0026] The first fixing device 1 is installed, and the specific implementation is as follows: S1: Before connecting the long stator module to the cable 6, pass the two bridging beams 11 through the back of the mounting bracket 4 in sequence; S2: Pre-install cable 6 to ensure that cable 6 can be tied and fixed to the cross-connecting beam 11; S3: Tighten the bridging beam 11 with nuts, connect the inter-module cable 6, and use the first binding strap 12 to bind and secure the cable 6 to the bridging beam 11. When binding, follow the principle of lower layer first and upper layer last. S4: Loosen the nut, install the support plate 13, and finally tighten the first fixing device 1 with the nut.

[0027] Specifically, such as Figures 11-14 As shown, the second fixing device 2 includes two connecting brackets 21 connected to the mounting bracket 4, and a support beam 22 is connected between the two connecting brackets 21. The connecting cables 6 on both sides of the long stator air gap are fixed to the support beam 22 by the second binding strap 23.

[0028] The support beam 22 extends from both ends of the two connecting brackets 21, and pins 24 are inserted therein; a layer of cable 6 is arranged on the upper and lower sides of the support beam 22. The connecting cables 6 on both sides of the long stator air gap can be tied in an orderly manner on both sides of the support beam 22 to achieve quick and orderly fixation of the cables 6 at this location.

[0029] The second fixing device 2 is used to fix the lower lead cable 6 of the long stator 5 of the linear motor. It mainly consists of connecting brackets 21 (2 sets), support beams 22 (1 set), pins 24 (2 sets), and second binding straps 23. The connecting brackets 21 are formed by cutting 50x50x4 equilateral angle steel. Two sets of bracket mounting holes are machined on one right-angle side, and one set of support beam mounting holes is machined on the other right-angle side. The two sets of connecting brackets 21 are completely identical. The support beam 22 is formed by cutting seamless steel pipe. Pin mounting holes are machined at both ends of the support beam 22. The pin holes penetrate the surface of the support beam 22. The pins 24 are national standard parts.

[0030] The second fixing device 2 is installed as follows: Y1: Install the two sets of connecting brackets 21 onto the long stator mounting bracket 4. The design of the two sets of mounting holes on the connecting brackets 21 can ensure that the installation of the connecting brackets 21 is not directional. Y2: Insert the support beam 22 through one of the end faces of the connecting bracket 21. After the support beam 22 passes through the end face of the connecting bracket 21 on the opposite side, fix the support beam 22 with the pin 24. Y3: After connecting cable 6, use the second binding strap 23 to bind and fix cable 6 to the support beam 22. When binding, follow the principle of lower layer first and upper layer last.

[0031] Specifically, such as Figures 15-19 As shown, the third fixing device 3 includes a fixing frame 31 and a partition plate 32. The fixing frame 31 includes a base plate 311 and several upright plates 312 disposed on the base plate 311. The base plate 311 is connected to the mounting bracket 4 by connecting bolts 33. Several layers of connecting bolts 33 and several layers of upright plates 312 separate several cables 6 vertically. The partition plate 32 passes through several upright plates 312 in sequence and separates several cables 6 horizontally. Several cables 6 are fixed to the partition plate 32 by a third binding strap 34.

[0032] The fixing frame 31 is connected to a cable box cover 35; the partition plate 32 is T-shaped, and its upper end is hung on the uppermost clamping bolt 33. The clamping bolt 33 and the upright plate 312 separate the cable 6 vertically, and the partition plate 32 can separate the inner and outer layers of cable 6 horizontally, so that the series cables 6 between the long stator modules on the same side can be arranged in an orderly manner on the third fixing device 3, which facilitates the quick and orderly fixing of the cable 6 at this location.

[0033] The third fixing device 3 is used to fix the connecting cable 6 between adjacent modules on the same side of the linear motor long stator 5. It mainly consists of a fixing frame 31, locking bolts 33, partition plates 32, cable box covers 35, third binding straps 34, and hexagon socket screws. The fixing frame 31 is welded from steel plates and consists of one base plate 311 and four upright plates 312. Four sets of locking holes are machined on the base plate 311, which are distributed in the same way as the mounting bracket holes. Three sets of cable box cover locking screw holes are machined on the top of the base plate 311. The four sets of upright plates 312 on the base plate 311 are arranged at a certain interval. The partition plate mounting hole is machined at the center of the upright plate 312. The hole size is about 2mm larger than the outer contour of the partition plate 32 to facilitate the installation of the partition plate 32. The partition plate 32 is machined from Q235 steel plate and is designed in a T shape. The two wings of the T shape are used for support and positioning of the partition plate 32 in the height direction. Two sets of oval holes are machined on the body of the partition plate 32 for binding and fixing the cable 6. The cable box cover 35 is integrally bent from a thin steel plate, and three sets of bolt holes are machined on the cable box cover 35.

[0034] The third fixing device 3 is installed, and the specific implementation is as follows: T1: Before connecting the long stator module to the cable 6, use the clamping bolts 33 to install the fixing bracket 31 onto the mounting bracket 4 between adjacent modules. During installation, all 4 sets of clamping bolts 33 pass through the back of the mounting bracket 4 and the nuts are tightened on the outside. T2: Insert the partition plate 32 into the fixing frame 31, and make sure that the two wings of the partition plate 32 are attached to the two bolt threads of the uppermost layer; T3: Connect the inner layer cables 6, a total of 6 cables, numbered 1#, 2#, 3#, 4#, 5#, and 6# from bottom to top. Cables 1#, 2#, 4#, and 5# are installed and fixed to the upright plate 312 of the fixing frame 31, and cables 3# and 6# are fixed to the connecting bolts 33. After the connection is completed, the third binding strap 34 passes through the oblong hole of the partition plate 32 and binds the cables 6 to the partition plate 32. T4: Connect the outer cable 6 according to the method for connecting the inner layer cable 6 in step T3; T5: Snap the cable box cover 35 and secure it with an Allen screw.

[0035] This invention has a wide range of applications and good compatibility: Existing technical solutions require the fabrication of multiple layers of clamps based on the position and shape of the connecting busbars, and the busbar connections must be wired in a specific order; otherwise, they will not match the clamps. The fixing device in this invention allows adjustment of the fixing beam position according to the position of the connecting cable 6, and only requires securing the cable 6 with straps.

[0036] This invention offers simple and efficient installation: Traditional methods require installing wire clamps in layers according to a specific sequence, then bolting them together for final fixation. The three structures involved in this invention allow for a single, integrated installation, involving only the tightening and loosening of bolts, making operation simple and convenient.

[0037] This invention offers a cost advantage: Existing solutions require the fabrication of various specifications of wire clamps based on the shape and position of each busbar layer. These clamps are mostly made of high-strength laminated glass cloth, and require standard impregnation and drying after processing, resulting in high overall costs. The structures described in this invention are all formed from conventional materials, involving lower process barriers and offering a significant cost advantage.

[0038] This invention is not limited to the above-described optional embodiments. Anyone can derive other various forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that falls within the scope of the claims of this invention shall be protected by this invention.
