Description

Technical Field

[0001] The present invention relates to the technical field of power equipment assembly, and in particular to a positioning and locking device for power equipment assembly. Background Art

[0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, mutual inductors, contactors, electrical cabinets, etc. With the advancement of science and technology, the power industry is becoming more and more developed, and power equipment is also developing rapidly. Therefore, the production and assembly of power equipment is also a top priority.

[0003] When assembling power equipment, some can be assembled on an assembly line. However, some power equipment is large in size, and assembly on an assembly line requires the power equipment to be placed on the assembly line for transportation, which is inconvenient for assembly. Another assembly method is to place the power equipment in a fixed position and transport the assembly parts to the assembly site for assembly. Generally, a lot of materials are needed when assembling power equipment, such as washers, nuts, screws, sealing gaskets, etc., and the assembly of a single device will use multiple materials of different models, so the position requirements of the equipment during the assembly process are relatively high.

[0004] At present, in the process of assembling power equipment, in order to ensure the stability of the assembled parts and prevent them from changing their position and being damaged by shaking during the assembly process, it is necessary to fix the power equipment parts during the assembly process. However, the existing fixing method is mainly fastened by bolts, which is relatively simple. The kinetic energy generated during the movement of the power equipment parts can only be consumed by themselves. The equipment is easily damaged and the energy generated during the movement of the equipment is insufficiently utilized, resulting in poor adaptability of the equipment parts when fixed.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Next, the present invention is described in detail with reference to schematic diagrams.

Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention.

[0039] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0040] The present invention provides a positioning and locking device for assembling electric equipment, which replaces the traditional method of fixing electric equipment during assembly, avoids the problem that the electric equipment has a single fixing method and needs to consume energy after being subjected to external force, thereby causing itself to be easily damaged and having poor adaptability during use.

[0041] Figures 1-8 The present invention shows a schematic diagram of a positioning and locking device for assembling power equipment. Figures 1-8 A detailed introduction is given to the positioning and locking device used for assembling this type of power equipment.

[0042] Example 1

[0043] refer to Figure 1-Figure 7The present invention discloses a positioning and locking device for assembling electric equipment, the main body of which includes a fixed shell 100, a positioning mechanism 200, a buffer mechanism 300 and a locking mechanism 400.

[0044] refer to Figure 1-Figure 7 The fixed housing 100 is used to facilitate the installation of the positioning mechanism 200, the buffer mechanism 300 and the locking mechanism 400. The fixed housing 100 includes a top housing 110 connected to the bottom of the equipment load-bearing plate, a middle housing 120 located at the bottom of the top housing 110, and a bottom housing 130 located at the bottom of the middle housing 120 and connected to the ground by bolts. The top housing 110 is used to facilitate the installation of the positioning mechanism 200, the middle housing 120 is used to facilitate the installation of the buffer mechanism 300, and the bottom housing 130 is used to facilitate the installation of the locking mechanism 400, and the stability of the entire device is maintained after being connected to the ground by bolts;

[0045] refer to Figure 1-Figure 5 The positioning mechanism 200 is used to automatically and accurately locate the position of the installed and assembled equipment during operation. The positioning mechanism 200 is located in the top shell 110. When the equipment is placed on the weighing plate, the positioning mechanism 200 automatically and accurately and quickly locates the installation position of the equipment components, thereby avoiding multiple displacements of the equipment during the installation and assembly process, which would cause inconvenience in installation and assembly.

[0046] refer to Figures 1-6 The buffer mechanism 300 is used to automatically buffer and absorb the energy generated during the installation and assembly of the device. The buffer mechanism 300 is located in the middle shell 120. When the positioning mechanism 200 starts to work, it automatically drives the buffer mechanism 300 to buffer and absorb the energy generated during the installation and assembly of the device. Therefore, when the positioning mechanism 200 positions the device, it automatically drives the buffer mechanism 300 to buffer the energy generated during the assembly of the device, thereby protecting the device and preventing the device from being damaged by collision.

[0047] refer to Figure 1-Figure 7 The locking mechanism 400 is used to lock the device. The locking mechanism 400 is located in the bottom shell 130. When the buffer mechanism 300 is working, it automatically drives the clavicle mechanism to work and locks the device. When the buffer mechanism 300 is working, it automatically drives the locking mechanism 400 to automatically lock the device that is being installed and assembled and positioned, thereby maintaining the stability of the device and avoiding the need for multiple tightening. At the same time, the energy generated by the buffer mechanism 300 when it is working is reused, thereby reducing the energy consumption of the device when it is working.

[0048] In this embodiment, the specific usage process is as follows: the equipment to be installed and assembled is placed on the top of the fixed shell 100 through the weighing plate, and the positioning mechanism 200 automatically starts working to position the equipment after being subjected to the pressure of the equipment. At the same time, the buffer mechanism 300 automatically buffers and absorbs the energy generated during the installation and assembly of the equipment to protect the equipment. When the buffer mechanism 300 is working, it drives the locking mechanism 400 to automatically lock the positioned equipment, thereby maintaining the stability of the equipment, and then synchronously positioning, buffering and locking the equipment, thereby making the fixation adaptability during the installation and assembly of the equipment higher, and at the same time utilizing the energy generated during the installation and assembly process to reduce the energy consumption during the operation of the device.

[0049] Example 2

[0050] Based on Example 1, Figures 1-4 The top housing 110 has a mounting bracket 110 a inside for facilitating the installation of the sun gear 210 ;

[0051] refer to Figure 1-Figure 5 The positioning mechanism 200 includes a sun gear 210 movably mounted in the mounting frame 110a, a planetary gear set 220 meshing with the inner wall of the sun gear 210, a positioning ratchet 230 located at the output end of the planetary gear set 220 and having a plurality of centrifugal ratchets on the outer wall, a positioning plate 240 located on the inner wall of the top shell 110 and having an annular rack 240a on the surface, and a power input assembly 250 transmission-connected to the sun gear 210. The sun gear 210 is used to drive the planetary gear set 220 to rotate when it rotates, and the planetary gear set 220 is used to drive the positioning ratchet 230 to rotate when it rotates. The positioning ratchet 230 is used to drive the centrifugal ratchets to expand and gradually engage in the annular rack 240a on the positioning plate 240 when it rotates. The power input assembly 250 is used to drive the sun gear 210 to rotate by its own gravity when the equipment is assembled.

[0052] In this embodiment, reference Figure 4 The top surface of the top shell 110 has a connecting groove 110b for conveniently connecting the first threaded rod 250a and the first threaded cylinder 250c;

[0053] refer to Figure 5 The outer wall of the sun gear 210 is evenly distributed with transmission serrations 210a, which are used to drive the sun gear 210 to rotate when the first gear 250b rotates;

[0054] refer to Figure 5The power input assembly 250 includes a first threaded rod 250a located in the top shell 110, a first gear 250b located at the bottom of the first threaded rod 250a and meshing with the transmission serrations 210a on the outer wall of the sun gear 210, and a first threaded barrel 250c threadedly connected to the first threaded rod 250a through the connecting groove 110b at the bottom. The first threaded rod 250a is used to drive the first gear 250b to rotate when it rotates, and the first gear 250b is used to drive the sun gear 210 to rotate when it rotates. The first threaded barrel 250c is used to drive the first threaded rod 250a when the top is pressed downward. 250a rotates, the outer side wall of the first threaded cylinder 250c has a limiting groove, and the inner wall of the connecting groove 110b has a limiting protrusion corresponding to the limiting groove, which is used to limit the first threaded cylinder 250c when it moves downward after the top of the first threaded cylinder 250c is subjected to pressure, thereby avoiding synchronous rotation with the first threaded rod 250a. The top of the first threaded cylinder 250c has a load-bearing block, and a plurality of reinforcing ribs are provided between the bottom of the load-bearing block and the side wall of the first threaded cylinder 250c, which are used to increase the strength of the top of the first threaded cylinder 250c, thereby avoiding the top of the first threaded cylinder 250c from being damaged under the heavy pressure of the equipment.

[0055] In this embodiment, the specific working process is as follows: when the top of the first threaded cylinder 250c is pressed by the equipment and moves downward, it drives the first threaded rod 250a to rotate under the limiting action of the connecting groove 110b, and when the first threaded rod 250a rotates, it drives the first gear 250b to rotate, and when the first gear 250b rotates, it drives the sun gear 210 to rotate, and when the sun gear 210 rotates, it drives the planetary gear set 220 to rotate, and when the planetary gear set 220 rotates, it drives the positioning ratchet 230 to rotate, and when the positioning ratchet 230 rotates, it drives the centrifugal ratchet to expand and gradually engage with the annular rack 240a of the positioning plate 240, so that the positioning ratchet 230 is gradually twisted and stuck in the annular rack 240a, thereby performing preliminary positioning of the equipment. At the same time, under the mutual meshing friction of multiple gears and the friction between the inner wall of the annular rack 240a and the centrifugal ratchet, the heat generated can remove ice and prevent freezing, thereby improving the working strength of the device in cold environments.

[0056] Example 3

[0057] Based on Example 2, Figures 1-6The buffer mechanism 300 includes a hydraulic cylinder 310 located inside the middle shell 120, a connecting seat 320 located at the top piston end of the hydraulic cylinder 310, and a first transmission assembly 330 that is transmission-connected to the positioning ratchet 230 at one end and transmission-connected to the connecting seat 320 at the other end. The hydraulic cylinder 310 is used to buffer and absorb energy during the up and down extension and contraction of the top piston. The connecting seat 320 is used to drive the piston at the top of the hydraulic cylinder 310 to perform reciprocating up and down piston motion in the hydraulic cylinder 310 when moving up and down. The first transmission assembly 330 is used to drive the connecting seat 320 to perform reciprocating up and down movement when the positioning ratchet 230 rotates.

[0058] In this embodiment, reference Figure 6 The first transmission assembly 330 includes a differential 330a connected to the bottom of the positioning ratchet 230 at one end, a connector 330b connected to the other end of the differential 330a at the top and movably engaged with the top of the middle housing 120, a bevel gear set 330c connected to the bottom of the connector 330b at one end, a crank 330d at the other end of the bevel gear set 330c, and a hinged rod 330e hinged to the crank 330d at one end and hinged to the top of the connecting seat 320 at the other end. 0a is used to position the ratchet 230 and drives it to rotate, accelerating the drive connecting piece 330b to rotate, the connecting piece 330b is used to drive the bevel gear set 330c to rotate when it rotates, and the bevel gear set 330c is used to drive the crank 330d to rotate when it rotates. The crank 330d is used to cooperate with the articulated rod 330e. When rotating, it drives the connecting seat 320 and the piston of the hydraulic cylinder 310 to perform reciprocating piston motion under the quantitative connection action of the articulated rod 330e, thereby automatically buffering and absorbing the energy generated during the installation and assembly of the equipment.

[0059] In this embodiment, reference Figures 1-6 The bottom of the mounting frame 110a has a heat conducting frame 110a-1, which is used to transfer the heat generated by the friction between the sun gear 210 and the planetary gear set 220 and the mounting frame 110a when the sun gear 210 rotates to the heat conducting rod 310a;

[0060] refer to Figures 1-6 The side wall of the hydraulic cylinder 310 is connected to the bottom of the heat-conducting frame 110a-1 through a heat-conducting rod 310a. The heat-conducting rod 310a is used to transfer the heat transferred from the heat-conducting frame 110a-1 to the inside of the hydraulic cylinder 310, thereby preventing the hydraulic oil inside the hydraulic cylinder 310 from becoming viscous in a low temperature environment, thereby causing the entire device to get stuck and unable to work normally.

[0061] In this embodiment, the specific working process is as follows: when the positioning ratchet 230 starts to rotate, it drives the differential 330a to rotate. When the differential 330a rotates, it drives the connecting piece 330b and the bevel gear set 330c to rotate at high speed. When the bevel gear set 330c rotates, it drives the crank 330d to rotate. When the crank 330d rotates, it drives the connecting seat 320 and the piston of the hydraulic cylinder 310 to move back and forth up and down in the hydraulic cylinder 310 under the connection of the hinged rod 330e, thereby automatically buffering and absorbing the energy generated during the installation and assembly of the equipment, thereby reducing damage to the equipment during installation and assembly. At the same time, the interior of the connecting seat 320 has a permanent magnet, so that when the connecting seat 320 moves back and forth up and down inside the hydraulic cylinder 310, it cuts the copper cylinder wall of the cylinder to generate eddy current, forming reverse electromagnetic damping, thereby suppressing the resonance of a specific frequency.

[0062] Example 4

[0063] Based on Example 3, Figures 1-8 The locking mechanism 400 includes a spiral limiting groove 410 located on the bottom inner wall of the bottom shell 130, a wedge-shaped slider 420 located in the spiral limiting groove 410, a winding rod 430 movably mounted on the bottom inner wall of the bottom shell 130, and a second transmission assembly 440 with one end transmission connected to the winding rod 430 and the other end transmission connected to the connecting seat 320. The spiral limiting groove 410 is used to facilitate the connection of the wedge slider 420. The wedge slider 420 is used to self-lock when sliding inside the spiral limiting groove 410. When the winding rod 430 is used to rotate, the wedge slider 420 is pulled to slide in the spiral limiting groove 410 by the connecting rope. The second transmission assembly 440 is used to drive the winding rod 430 to rotate when the connecting seat 320 moves up and down. The winding rod 430 is wrapped with a connecting rope with the other end connected to the top of the wedge slider 420, which is used to pull the wedge slider 420 to slide in the spiral limiting groove 410 when the winding rod 430 rotates.

[0064] In this embodiment, the cross-section of the spiral limiting groove 410 is a gradient structure, and both sides of the wedge-shaped slider 420 have self-locking inclined surfaces for gradually being limited and locked when the wedge-shaped slider 420 slides in the spiral limiting groove 410.

[0065] In this embodiment, reference Figure 7-Figure 8 The wedge-shaped slider 420 has an elastic locking tongue 420a on the side adjacent to the winding rod 430, and a plurality of locking grooves are evenly distributed on the inner wall of the spiral limiting groove 410 adjacent to the elastic locking tongue 420a. When the wedge-shaped slider 420 slides in the spiral limiting groove 410, the elastic locking tongue 420a gradually extends out under the centripetal force and collides with the inner walls of the plurality of locking grooves until the wedge-shaped slider 420 stops sliding in the spiral limiting groove 410 and completes self-locking.

[0066] In this embodiment, reference Figure 7 The second transmission assembly 440 includes a second threaded rod 440a located at the top of the winding rod 430 and a second threaded sleeve with a connecting rod on the side wall connected to the side wall of the connecting seat 320 and threadedly sleeved on the second threaded rod 440a. A connecting assembly (not shown in the figure) is connected between the second threaded rod 440a and the top of the winding rod 430. The connecting assembly includes a ratchet connecting seat 320 with a ratchet groove on the side wall and a ratchet located in the ratchet groove and with an elastic pawl on the side wall, so that when the connecting seat 320 moves up and down, the second threaded rod 440a is driven to move up and down, and then under the connection action of the connecting assembly, the second threaded rod 440a is driven to rotate in one direction all the time, thereby driving the winding rod 430 to rotate and reeling the connecting rope.

[0067] In this embodiment, the specific working process is as follows: when the connecting seat 320 moves up and down reciprocatingly, it drives the second threaded cylinder 440b to move up and down, thereby driving the second threaded rod 440a to rotate. When the second threaded rod 440a rotates, it drives the winding rod 430 to rotate and reel in the connecting rope. The connecting rope pulls the wedge-shaped slider 420 to slide in the spiral limiting groove 410. At the same time, the elastic locking tongue 420a gradually extends under the centripetal force, thereby gradually colliding with multiple locking grooves, and cooperating with the spiral limiting groove 410 with a gradually smaller cross-section, so that the wedge slider 420 is automatically locked, so that the winding rod 430 stops rotating, completing the locking of the device and maintaining the stability of the device.

[0068] When the elastic lock tongue 420a is thrown out and hits the inner wall of the lock slot under the action of centripetal force, high-frequency micro-vibration is generated, which deforms and fills the microscopic burrs between the device and the device, eliminating the installation gap (vibration eliminates the gap);

[0069] At the same time, when the wedge-shaped slider 420 slides at high speed in the spiral limit groove 410, ultrasonic waves (20-40kHz) are excited in the grease film in the spiral limit groove 410, generating a cavitation effect, removing oxides on the contact surface, and preventing micro-motion wear (acoustic wave anti-micro-motion wear).

[0070] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
