Description

Technical Field

[0001] This utility model relates to the field of motor assembly installation technology, and in particular to a motor assembly installation structure. Background Technology

[0002] In industrial equipment transmission systems, the stable installation of the motor assembly is a key factor in ensuring reliable equipment operation. Traditional motor mounting structures employ a three-stage bolt connection system for power transmission and fixation: the foundation connection layer anchors the motor base to a concrete foundation or metal bracket using anchor bolts; the main connection layer uses positioning bolts to achieve a rigid connection between the motor and the base; and the transmission connection layer uses coupling bolt assemblies and key connections to achieve coaxial coupling between the motor shaft and driven shafts such as pump shafts and gear shafts.

[0003] In actual installation, bolts are prone to electrochemical corrosion in humid, dusty, or corrosive environments (e.g., the formation of galvanic cells after the zinc plating of carbon steel bolts is damaged), leading to thread jamming, breakage, and even motor displacement and excessive coaxiality deviation, resulting in increased equipment vibration and bearing wear. Furthermore, existing structures require the sequential installation of multiple components such as the base, motor, coupling, and protective cover, involving the repeated tightening of 10-20 bolts alone, which is unsuitable for automated assembly requirements. Moreover, maintenance requires the individual removal of corroded bolts, which is time-consuming in space-constrained scenarios (such as downhole pump motors and dense equipment arrays). Therefore, a new motor assembly installation structure needs to be designed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a motor assembly mounting structure to solve the problems of bolts being prone to corrosion and failure in humid and dusty environments, as well as the problems of existing structures having many bolts, difficulty in automating installation, and time-consuming disassembly in space-constrained scenarios.

[0006] This utility model embodiment adopts the following technical solution: a motor assembly mounting structure. It mainly includes a motor assembly having a base; a mounting assembly disposed below the base, the mounting assembly including a mounting base plate for supporting the base, two sets of limiting strips symmetrically welded to the mounting base plate, the two sets of limiting strips having a parallel spacing, and the limiting strips having an L-shaped structure; each set of limiting strips has a U-shaped sliding groove on its inner sidewall, slide rails are provided on both sides of the base, and extensions are symmetrically welded to the mutually distant sides of the two sets of limiting strips; a locking assembly is installed at each extension, the locking assembly being used to fix the motor assembly in the correct position between the two sets of limiting strips, and a rain cover is connected to the side of the extension via a spring hinge.

[0007] Furthermore, the locking assembly includes a fixed seat mounted on the extension, the fixed seat having a protrusion, a hinge handle movably connected to the protrusion via a pin, a hooking part movably connected to the hinge handle via a pin, the base end face of the motor assembly, and a mating part adapted to the hooking part.

[0008] Furthermore, sealing gaskets are embedded on the contact surfaces of the rain cover, the extension, and the base.

[0009] Furthermore, limit components are symmetrically installed on the upper surface of the two sets of limit bars at the end away from the locking component, and the limit components are made of stainless steel.

[0010] Furthermore, the limiting component includes a base mounted on the upper surface of the limiting strip. Its main body has a U-shaped structure with limiting portions extending vertically on both sides. A horizontal through hole is provided on the base, and a movable pin movably passes through the horizontal through hole. The movable pin can slide along the axial direction of the horizontal through hole. A handle is provided on the surface of the movable pin, and a pin seat adapted to be inserted into the movable pin is installed on the base.

[0011] Furthermore, through holes are made at the four corners of the mounting base plate, and it is fixed to the ground or foundation platform by expansion bolts.

[0012] Furthermore, the sealing gasket is made of rubber.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] A motor assembly mounting structure enables rapid positioning of the motor assembly through the sliding engagement of the base slide rail and the U-shaped slide groove of the limiting strip. Combined with the lever self-locking structure of the locking component, tool-free fixation is achieved, making it suitable for automated assembly requirements. In terms of maintenance convenience, disassembly only requires operating the hinge handle and movable pin, eliminating the need to deal with rusted bolts, significantly reducing maintenance time. This is particularly suitable for space-constrained scenarios such as underground drilling and dense equipment arrays. For adaptability to harsh environments, a rain cover combined with a sealing gasket forms a waterproof and dustproof barrier, isolating the locking components from moisture, dust, and corrosive substances, preventing connection failure due to corrosion.

Detailed Implementation

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-2 As shown, this utility model embodiment provides a motor assembly mounting structure, including a motor assembly 1, which includes a drive motor 11, a coupling 12 and a pump body 13. The output shaft of the drive motor 11 is rigidly fixed to one end of the coupling 12 by a key connection. The connection between the coupling 12 and the pump body 13 adopts a composite structure of a shrink sleeve and a flange positioning. The above connection method is the prior art and will not be described in detail here.

[0026] like Figures 3-4As shown, a base 14 is fixedly installed at the bottom of the motor assembly 1, and a mounting component 2 for supporting the motor assembly 1 is provided at the lower end of the base 14. The mounting component 2 includes a mounting base plate 21 for supporting the base 14, which is integrally formed from Q235B steel plate. Through holes are opened at the four corners of the mounting base plate 21 for fixing to the ground or foundation platform by expansion bolts. Two sets of limiting strips 22 are symmetrically welded on the mounting base plate 21. The two sets of limiting strips 22 have parallel spacing and are adapted to the outer contour of the base 14 to form a lateral limiting space. The limiting strip 22 has an L-shaped structure.

[0027] Each set of limiting strips 22 has a U-shaped groove on its inner sidewall. The groove is machined by milling. The base 14 of the motor assembly 1 has slide rails (not shown) on both sides that match the U-shaped groove. The slide rails are inserted into the groove, so that the motor assembly 1 can slide laterally along the limiting strips 22. When the motor assembly 1 slides to the point where the sidewall of the base 14 is in close contact with the inner wall of the right-angle end of the limiting strip 22, the motor assembly 1 is in the correct position between the two sets of limiting strips 22, achieving rapid positioning.

[0028] Furthermore, extensions 23 are symmetrically welded to the two sets of limiting bars 22 on opposite sides. A locking assembly 3 is installed at each set of extensions 23. The locking assembly 3 is used to fix the motor assembly 1 between the two sets of limiting bars 22. The locking assembly 3 includes a fixing seat 31 fixedly installed on the extension 23. The fixing seat 31 has a protrusion 32. A hinge handle 33 is movably connected to the protrusion 32 via a pin, providing a rotation fulcrum for the hinge handle 33. A hook part 34 is movably connected to the hinge handle 33 via a pin. Correspondingly, a mating part 35 adapted to the hook part 34 is fixedly provided on the end face of the base 14 of the motor assembly 1.

[0029] During installation, rotate the hinge handle 33 to engage the hook part 34 with the mating part 35. Using lever and self-locking principles, the base 14 of the motor assembly 1 is pressed tightly against the limit strip 22 to achieve locking. During disassembly, reverse the operation of the hinge handle 33 to release the lock and complete the assembly and disassembly of the motor assembly 1.

[0030] Meanwhile, a rain cover 37 is connected to the side of the extension 23 via a spring hinge. The rain cover 37 is covered on the locking component 3 by default. When the locking component 3 needs to be operated, the rain cover 37 can be rotated to overcome the torsion spring force, and the hinge handle 33 can be exposed for manual operation.

[0031] In this application, sealing gaskets are embedded on the contact surfaces of the rain cover 37 with the extension 23 and the base 14, and the sealing gaskets are made of rubber. Under the pre-tightening force of the spring hinge, the sealing gaskets are tightly attached to the surfaces of the extension 23 and the base 14 to form a waterproof sealing structure, effectively preventing rainwater from seeping into the locking assembly 3;

[0032] When the motor assembly 1 is in the locked state, the rain cover 37 automatically closes under the action of the spring hinge, and the sealing gasket forms a waterproof barrier to prevent rainwater, dust, etc. from entering the locking component 3, thus extending its service life. When it is necessary to disassemble the motor assembly 1, the operator only needs to flip the rain cover 37 to complete the unlocking operation. After the operation is completed, the rain cover 37 is released, and it automatically resets and reseales under the action of the torsion spring.

[0033] To ensure a secure lock on the fixed motor assembly 1, such as... Figures 2-3 As shown, limit components 4 are symmetrically installed on the upper surface of the two sets of limit bars 22 away from the locking component 3. The limit components 4 are made of stainless steel. The limit components 4 include a base 41 fixedly installed on the upper surface of the limit bar 22. Its main body is U-shaped, with limit portions 42 extending vertically on both sides to form a lateral constraint on the movable pin 43. A horizontal through hole is opened on the base 41, and the movable pin 43 moves through the horizontal through hole. The movable pin 43 can slide along the axial direction of the horizontal through hole. A handle 45 is provided on its surface for easy manual operation. At the same time, a pin seat 44 adapted to be inserted into the movable pin 43 is fixedly installed on the base 14. An insertion hole complementary to the shape of the head of the movable pin 43 is opened inside. When the movable pin 43 is inserted into the pin seat 44, a mechanical locking structure is formed.

[0034] After the motor assembly 1 is slid to the correct installation position and initially fixed by the locking component 3, the operator holds the handle 45 of the movable pin 43 and pushes the movable pin 43 into the insertion hole of the pin seat 44 along the horizontal through hole of the base 41. The axial displacement of the motor assembly 1 is restricted by the cooperation between the movable pin 43 and the pin seat 44. When disassembling, the movable pin 43 is pulled in the opposite direction to disengage from the pin seat 44, and the limiting constraint can be released.

[0035] Working principle: During installation, first align the slide rails on both sides of the base 14 at the bottom of the motor assembly 1 with the U-shaped groove inside the limiting strip 22. By sliding laterally, the side wall of the base 14 is brought into contact with the inner wall of the right-angle end of the limiting strip 22, completing the initial positioning. At this time, the locking component 3 is used for the first fixation: the operator rotates the hinge handle 33, which drives the hook part 34 to hook with the mating part 35 on the end face of the base 14. With the help of the lever and self-locking structure, the base 14 is pressed tightly onto the limiting strip 22, restricting the lateral displacement of the motor assembly 1.

[0036] Subsequently, a secondary locking is achieved through the limiting component 4. By grasping the handle 45 of the movable pin 43, it is pushed into the pin seat 44 insertion hole of the base 14 along the horizontal through hole of the base 41, forming a mechanical lock and further restricting the axial movement of the motor assembly 1. The dual locking mechanism ensures that the motor assembly 1 maintains a stable position under operating conditions such as vibration and impact loads, and avoids transmission failure caused by coaxiality deviation.

[0037] During use and maintenance, the rain cover 37 automatically closes via a spring hinge. The rubber sealing gaskets on the contact surfaces of the rain cover 37, extension 23, and base 14 form a waterproof barrier under the pre-tightening force of the hinge, preventing rainwater and dust from corroding the locking assembly 3 and extending the life of the components. When it is necessary to disassemble the motor assembly 1, first flip the rain cover 37 to release the locking of the hook part 34 and the docking part 35, and then pull the movable pin 43 in the opposite direction to disengage it from the pin seat 44. The motor assembly 1 can then be slid out along the slide groove to complete the disassembly.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
