Description

Technical Field

[0001] This utility model relates to the technical field of motor testing equipment, specifically to a motor testing platform with an embedded insulating pad. Background Technology

[0002] After a motor is damaged and repaired, it needs to be placed on an experimental platform to conduct an electrical test to check whether it can operate normally. The experimental platform is equipped with an electrical control cabinet on top, which controls the motor's start, stop, forward and reverse rotation, as well as the detection of the motor's resistance and insulation.

[0003] Existing motor testing platforms often employ simple support structures, which suffer from insufficient insulation, fixed installation positions for the electrical control cabinet, and poor stability. Specifically, the insulating mat is typically laid directly on the platform surface, and its edges are prone to curling and wear, resulting in inadequate insulation. For the electrical control cabinet, additional supports are usually welded to the top of the platform for mounting and securing. However, the fixed position of these additional supports prevents any repositioning of the control cabinet. Furthermore, the motor testing platform itself is often not properly secured, or relies on ordinary bolt holes for fixing, resulting in poor seismic resistance and instability. Summary of the Invention

[0004] This invention addresses the problems of insufficient insulation protection, fixed installation position of electrical control cabinet, and poor stability in existing motor test platforms by providing a motor test platform with an embedded insulating pad. The insulating pad is embedded in the top of the platform, effectively preventing the edges of the insulating pad from curling and wearing, thus improving insulation protection performance. Simultaneously, it allows the electrical control cabinet to be fixed in different positions as needed, enabling flexible arrangement of electrical control holes. Furthermore, it improves the platform's anti-tipping ability and stability.

[0005] To achieve the above objectives, the technical solution of this utility model is: a motor test platform with an embedded insulating pad, comprising a test platform, a platform base, and an insulating pad disposed on the platform base. A concave groove is formed on the top of the platform base, and the perimeter of the concave groove forms a frame. The insulating pad is embedded and fixed inside the concave groove. By embedding the insulating pad into the concave groove, the curling and wear of the insulating pad's edges can be effectively prevented, and the frame around the concave groove protects the edges of the insulating pad.

[0006] The insulating pad has several upward-facing holes, and the platform base has downward-facing holes corresponding to the positions of the upward-facing holes. A through-hole is formed inside the downward-facing hole, penetrating the platform base. Expansion bolts can be inserted into the upward-facing holes, downward-facing holes, and through-holes to fix the platform base to the ground, thereby improving the overturning resistance and stability of the experimental platform.

[0007] The experimental platform is provided with several sets of mounting holes, each set including several mounting positions, and each mounting position is detachably fitted with a fixing component; grounding terminals are symmetrically arranged on both sides of the platform base. The mounting holes allow the electrical control cabinet to be installed in different locations, and the fixing components at the mounting positions secure the cabinet.

[0008] Furthermore, the concave groove has a rectangular structure and matches the insulating pad. The insulating pad is embedded and fixed inside the concave groove by an adhesive. The depth of the concave groove is greater than the thickness of the insulating pad, ensuring that the insulating pad can be completely embedded inside the concave groove, thereby avoiding curling and wear at the edge of the insulating pad and improving the insulation protection performance.

[0009] Furthermore, each of the upper countersunk holes is formed at the corner of the insulating pad. The diameter of the upper countersunk hole is the same as the diameter of the lower countersunk hole, and the diameter of the lower countersunk hole is larger than the diameter of the through hole. The upper countersunk hole, lower countersunk hole and through hole are coaxial from top to bottom and interconnected with each other.

[0010] Furthermore, expansion bolts for fixing the platform base are provided in the upper countersunk hole, lower countersunk hole and through hole. A sealing cap is detachably provided at the upper countersunk hole. The expansion bolts are used to stably fix the platform base to the ground and improve the anti-overturning ability.

[0011] Furthermore, each set of mounting holes includes three mounting positions. The countersunk holes and the three mounting positions are arranged in a square on the experimental platform. The mounting positions include countersunk holes and threaded holes that correspond to each other. Through the cooperation of the countersunk holes and threaded holes with the fastener, the fastener can fix the electrical control cabinet to the top of the experimental platform.

[0012] Furthermore, the threaded hole is formed on the platform base, the countersunk hole is formed on the insulating pad and is coaxial with the threaded hole, and the fixing member is a fixing screw that mates with the threaded hole. The fixing screw mates with the threaded hole to fix the electrical control cabinet to the top of the experimental platform.

[0013] Furthermore, the bottom of the platform base is symmetrically provided with strip-shaped outer grooves, and a strip-shaped inner groove is provided at the corresponding position of the strip-shaped outer groove. The width of the strip-shaped inner groove is greater than the width of the strip-shaped outer groove. When the experimental platform is moved, the lifting strap is passed through the strip-shaped inner groove to facilitate the lifting of the experimental platform.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: This utility model has a reasonable structure and good performance. By embedding and fixing the insulating pad on the top of the platform, it can effectively avoid the phenomenon of curling and wear of the edge of the insulating pad, thus improving the insulation protection performance. It can fix the electrical control cabinet at different positions on the top of the platform as needed, and can change the installation position of the electrical control cabinet, thus realizing flexible arrangement of the electrical control cabinet. It can also improve the platform's anti-overturning ability and improve stability.

[0015] This invention provides an installation position for the insulating pad by opening a concave groove on the top of the platform base. The insulating pad is embedded in the concave groove, and the depth of the concave groove is greater than the thickness of the insulating pad, which can prevent the edge of the insulating pad from curling and wearing. The frame around the concave groove protects the edge of the insulating pad.

[0016] This invention improves the anti-overturning ability and stability of the experimental platform by installing expansion bolts inside the upper and lower countersunk holes and through holes, and using the function of the expansion bolts to fix the platform base to the ground; the design structure of the upper and lower countersunk holes can hide the heads of the expansion bolts, thereby improving the safety level.

[0017] This utility model utilizes several sets of mounting holes to allow the electrical control cabinet to be installed at different locations on the top of the experimental platform, enabling the installation position of the electrical control cabinet to be changed according to requirements. Each set of mounting holes includes several mounting positions, which can be used to change the orientation of the electrical control cabinet, allowing for flexible arrangement of the cabinet. The cabinet is fixed in place by fasteners at the mounting positions. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-5 As shown, a motor test platform with an embedded insulating pad includes a test platform, which includes a platform base 1 and an insulating pad 6 disposed on the platform base 1. A concave groove 2 is formed on the top of the platform base 1, and the periphery of the concave groove 2 forms a frame 3. The insulating pad 6 is embedded and fixed inside the concave groove 2. In this embodiment, the platform base 1 and the insulating pad 6 are combined to form an experimental platform. The platform base 1 is made of Q235B steel plate with dimensions of 2500×1500×25mm and a thickness of 25mm, which can meet the needs of a 315KW motor. The depth of the concave groove 2 is 5.1mm, and the dimensions of the concave groove 2 are 2380×1380×5.1mm. After the concave groove 2 is opened on the top of the platform base 1, a 10mm wide frame 3 is formed around the concave groove 2. The thickness of the insulating pad 6 is 5mm. The concave groove 2 provides an assembly position for the insulating pad 6. The frame 3 around the concave groove 2 protects the edge of the insulating pad 6. The insulating pad 6 is made of nitrile rubber with a Shore hardness of 70A and a green RAL6029 standard color.

[0021] The insulating pad 6 has several upper countersunk holes 7, and the platform base 1 has lower countersunk holes 4 at the corresponding positions of the upper countersunk holes 7. A through hole 5 penetrating the platform base 1 is formed inside the lower countersunk hole 4. In this embodiment, the insulating pad 5 has four upper countersunk holes 7, and correspondingly four lower countersunk holes 4 and four through holes 5. The upper countersunk holes 7, lower countersunk holes 4, and through holes 5 form a composite mounting hole structure, which, in conjunction with expansion bolts, can fix the experimental platform to the ground, thereby improving the platform's anti-overturning ability and stability.

[0022] The experimental platform is provided with several sets of mounting holes, each set including several mounting positions, and a fixing component is detachably installed at each mounting position. Grounding terminals 10 are symmetrically arranged on both sides of the platform base 1. In this embodiment, each set of mounting holes is located at the corner of the experimental platform, i.e., the electrical control cabinet is fixed at the corner of the top of the experimental platform. The fixing component, in conjunction with the mounting positions, secures the electrical control cabinet to the top of the experimental platform, thus providing a fixing function. The grounding terminal 10 uses an M12 brass bolt and is used to connect to the grounding wire of the electrical control cabinet to prevent leakage accidents.

[0023] The concave groove 2 has a rectangular structure and matches the insulating pad 6. The insulating pad 6 is embedded and fixed inside the concave groove 2 by adhesive. The depth of the concave groove 2 is greater than the thickness of the insulating pad 6. The purpose is to ensure that the insulating pad 6 can be embedded and fixed inside the concave groove 2, and to protect the edge of the insulating pad 6 with the frame 3, thereby extending the service life of the insulating pad 6.

[0024] Each of the aforementioned countersunk holes 7 is located at a corner of the insulating pad 6. The diameter of the countersunk hole 7 is the same as the diameter of the countersunk hole 4, and the diameter of the countersunk hole 4 is larger than the diameter of the through hole 5. The countersunk holes 7, countersunk holes 4, and through holes 5 are coaxial from top to bottom and interconnected. In this embodiment, the diameter of the countersunk hole 7 is 50 mm and the depth is 5 mm, the diameter of the countersunk hole 4 is 50 mm and the depth is 15 mm, and the diameter of the through hole 4 is 16 mm.

[0025] Expansion bolts for fixing the platform base 1 are installed in the upper countersunk hole 7, lower countersunk hole 4, and through hole 5. A sealing cap 8 is detachably installed in the upper countersunk hole 7. In this embodiment, the expansion bolts are inserted into the upper countersunk hole 7, lower countersunk hole 4, and through hole 5 to stably fix the platform base 1 to the ground. The countersunk hole structure of the upper countersunk hole 7 and lower countersunk hole 4 can hide the head of the expansion bolts, improving the safety level. The sealing cap 8 mainly plays a sealing and protective role, effectively preventing dust and impurities from entering the upper countersunk hole 7 and lower countersunk hole 4. The sealing cap 8 is made of nylon material, with a cap brim diameter of 55mm and a sealing ring.

[0026] Each set of mounting holes includes three mounting positions. The countersunk hole 7 and the three mounting positions are arranged in a square on the experimental platform. The mounting positions include countersunk holes and threaded holes that correspond to each other. In this embodiment, the countersunk holes and threaded holes cooperate with the fasteners to fix the electrical control cabinet to the top of the experimental platform. The design structure of the three mounting positions allows the orientation of the electrical control cabinet to be changed, achieving flexible arrangement of the electrical control.

[0027] The threaded hole is formed on the platform base 1, and the countersunk hole is formed on the insulating pad 6 and is coaxially arranged with the threaded hole. The fixing component is a fixing screw 9 that mates with the threaded hole. In this embodiment, the electrical control cabinet is threadedly fixed to the top of the experimental platform by the threaded engagement of the fixing screw 9 with the threaded hole. The fixing screw 9 is an M12 countersunk Phillips head screw.

[0028] The platform base 1 has symmetrically formed outer strip grooves 11 at its bottom, and corresponding inner strip grooves 12 are formed at the positions of the outer strip grooves 11. The width of the inner strip groove 12 is greater than the width of the outer strip groove 11. In this embodiment, the platform base 1 has two outer strip grooves 11 at its bottom, and there are also two corresponding inner strip grooves 12. When the experimental platform is hoisted and moved, a sling is used, with one end passing through the inner strip groove 12, to facilitate hoisting the experimental platform by a crane. After the experimental platform is hoisted to the designated position, the sling is then pulled out of the inner strip groove 12.

[0029] When using this invention, after the experimental platform is hoisted to the installation position, expansion bolts are used to fix the four corners of the platform base 1. The expansion bolts are then passed through the upper countersunk hole 7, the lower countersunk hole 4, and the through hole 5 in sequence and fixed to the ground. The experimental platform is fixed to the ground by the expansion bolts. Then, a sealing cap 8 is installed at each upper countersunk hole 7. The installation position of the electrical control cabinet is determined according to actual needs. The electrical control cabinet is fixed at any corner of the top of the insulating pad 6. The electrical control cabinet is placed on top of the insulating pad 6, and the mounting holes of the electrical control cabinet are aligned with the countersunk holes and threaded holes. Then, fixing screws 9 are passed through the mounting holes, countersunk holes, and threaded holes to fix the electrical control cabinet to the top of the insulating pad 6. Two or three fixing screws 9 are used to fix the electrical control cabinet. Finally, the grounding wire of the electrical control cabinet is connected to the grounding terminal 10. Then, the repaired motor can be placed on the top of the insulating pad 6 for testing.

[0030] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
