Description

Technical Field

[0001] The utility model relates to the technical field of motor installation structures, in particular to a motor fixing and supporting device. Background Art

[0002] When the motor is in use, whether it is installed on the equipment or on the concrete base, it needs to be supported and fixed by the base. The base is used to install and fix the motor, and it is an important structure to ensure that the motor can work stably.

[0003] Most existing support devices are provided with bolt holes for fixing the motor. When installing the motor, the bolt fixing holes on the motor fixing base plate need to be calibrated and aligned with the bolt holes on the support device. However, the motor fixing base plate is mostly directly supported on the top of the support device, and the contact area with the horizontal surface of the top of the support device is large, resulting in a large relative friction resistance between the motor and the support device, making it difficult to push and shift for calibration, and the operation is relatively troublesome and inconvenient. Utility Model Content

[0004] The disclosed embodiment relates to a motor fixing support device to solve the problem that the contact area between the fixed base plate of the motor and the horizontal surface of the top of the support device is large, resulting in large relative friction resistance between the motor and the support device, making it difficult to be pushed and displaced for calibration.

[0005] In a first aspect of the present disclosure, a motor fixing support device is provided, which specifically comprises: a mounting base and a motor, wherein the mounting base is in a U-shaped structure as a whole, and the top end is used to carry and install the motor;

[0006] A push frame is slidably installed through the middle position of the top plate of the mounting base, and the push frame as a whole is composed of a bottom Japanese-shaped force frame and two transverse top shafts welded to the top of the Japanese-shaped force frame in a front-to-back symmetrical manner; two non-through transverse placement grooves are symmetrically opened on the top plate of the mounting base, and under normal conditions, the two transverse top shafts are inserted and hidden inside the two transverse placement grooves;

[0007] The driving shaft is rotatably installed at the middle position of the inner part of the mounting base, and two push rods are welded on the driving shaft in a symmetrical manner. The two push rods are turned upward and abut against the Japanese-shaped force frame, and the left end part of the driving shaft is covered with a driven gear; a rack is slidably installed on the bottom of the top plate of the mounting base through the pulling and sliding of a tension spring, and the rack is meshed with the driven gear to drive the push frame to slide upward to push and separate the motor from the mounting base. During the calibration and alignment operation, the push frame 3 can slide upward to push and separate the motor 2 and the mounting base 1, so that the fixed plate of the motor 2 is separated from the top horizontal surface of the mounting base 1, and the load is abutted against the two horizontal top shafts 301, and the sliding movement is adjusted by the two horizontal top shafts 301. The two horizontal top shafts 301 are strip-shaped structures with limited widths and a small sliding contact area with the fixed plate of the motor 2, which can effectively reduce the friction resistance of the motor 2 pushing activity, so that the motor 2 can be relatively easily pushed and displaced to implement calibration and alignment, so as to solve the problem that the calibration and alignment operation is relatively troublesome and inefficient;

[0008] The cross-sectional circular structure of the two transverse top shafts 301 is in tangential contact with the fixed base plate of the motor 2. The overall gravity of the motor 2 is transmitted to the two transverse top shafts 301 through the tangents generated by the abutment contact between its fixed base plate and the two transverse top shafts 301. This can further reduce the friction resistance between the motor 2 and the push frame 3, and solve the problem that the calibration and alignment operation is not convenient and labor-saving enough.

[0009] The utility model provides a motor fixing support device, which has the following beneficial effects:

[0010] The utility model discloses that when calibrating and aligning the bolt fixing holes and the bolt through-holes, the pushing frame can slide upward to push and separate the motor and the mounting base, so that the fixing plate of the motor is separated from the top horizontal surface of the mounting base, and the load is against the two horizontal top shafts, and the sliding movement and adjustment of the two horizontal top shafts are carried out. The two horizontal top shafts are in the form of strips with limited width and the sliding contact area with the motor fixing plate is small. Compared with the prior art that sets the fixing plate of the motor to be in direct large-area contact with the mounting base during calibration and alignment operations, the friction resistance of the motor pushing activity can be effectively reduced, so that the motor can be relatively easily pushed and displaced to implement calibration and alignment, and the operation is convenient, labor-saving and efficient.

[0011] In addition, the circular cross-sectional structure of the two lateral top shafts is in tangential contact with the fixed base plate of the motor. The overall gravity of the motor is transmitted to the two lateral top shafts through the tangents generated by the abutment contact between its fixed base plate and the two lateral top shafts. This can further reduce the friction resistance between the motor and the push frame, making the calibration and alignment operation more convenient and labor-saving.

[0012] In addition, under normal conditions, the two horizontal top shafts are inserted and hidden inside the two horizontal placement grooves, so that the top horizontal surface of the mounting base remains flat, and the motor's fixing plate can be in contact with the top horizontal surface of the mounting base over a large area as a whole, which helps to ensure the stability of the motor's installation and normal operation.

[0013] In addition, the rocker arm and the vertical positioning shaft together form a lever mechanism. The part of the rocker arm located at the rear side of the vertical positioning shaft is the power arm, and the part located at the front side of the vertical positioning shaft is the resistance arm. The length of the power arm is much larger than the resistance arm, and thus the lever mechanism is a labor-saving lever. Through this labor-saving lever, the jacking frame can be driven to slide up relatively easily, making the jacking operation of the motor more labor-saving and convenient.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1: Please refer to Figures 1 to 6 :

[0029] For the convenience of explanation, the long side of the Japanese character force frame 302 is marked as the left-right direction, and the short side of the Japanese character force frame 302 is marked as the front-back direction;

[0030] This embodiment provides a motor fixing support device, including: a mounting base 1 and a motor 2, the mounting base 1 is an overall U-shaped structure, the top end is used to carry and install the motor 2, four bolt through holes are symmetrically opened on the top plate of the mounting base 1, and two bolt fixing holes are symmetrically opened on the two fixing plates at the bottom of the motor 2;

[0031] The top plate 301 of the two lateral top shafts 301 is slidably installed in the middle position of the top plate of the mounting base 1, and the top push frame 3 is composed of a bottom Japanese-shaped force frame 302 and two horizontal top shafts 301 welded to the top of the Japanese-shaped force frame 302 in a front-to-back symmetrical manner. The top push frame 3 can slide upward to push and separate the motor 2 and the mounting base 1 when calibrating and aligning the bolt fixing holes and the bolt penetration holes, so that the fixing plate of the motor 2 is separated from the top horizontal surface of the mounting base 1, and the bearing is against the two horizontal top shafts 301, and the sliding movement is adjusted by the two horizontal top shafts 301. The two horizontal top shafts 301 are strip-shaped structures with limited width and a small sliding contact area with the fixing plate of the motor 2. Compared with the prior art of setting the fixing plate of the motor 2 to be in direct large-area contact with the mounting base 1 during calibration and alignment operations, the friction resistance of the motor 2 pushing activity can be effectively reduced, so that the motor 2 can be relatively easily pushed and displaced to implement calibration and alignment, and the operation is convenient, labor-saving and efficient.

[0032] The cross-section of the two transverse top shafts 301 is a circular structure, and they are in tangential contact with the fixed bottom plate of the motor 2. The overall gravity of the motor 2 is transmitted to the two transverse top shafts 301 through the tangent generated by the contact between its fixed bottom plate and the two transverse top shafts 301, which can further reduce the friction resistance between the motor 2 and the push frame 3, making the calibration and alignment operation more convenient and labor-saving;

[0033] Two non-through transverse placement grooves 104 are symmetrically opened on the top plate of the mounting base 1. Under normal circumstances, the two transverse top shafts 301 are inserted and hidden inside the two transverse placement grooves 104, so that the top horizontal surface of the mounting base 1 remains flat, and the fixing plate of the motor 2 can be in contact with the top horizontal surface of the mounting base 1 over a large area as a whole, which helps to ensure the stability of the installation and normal operation of the motor 2.

[0034] A driving shaft 107 is rotatably installed in the middle position of the inner part of the mounting base 1, and two push rods 1071 are welded on the driving shaft 107 in a symmetrical manner. The two push rods 1071 are flipped upward and come into contact with the Japanese-shaped force frame 302. Through the two push rods 1071, the driving shaft 107 can be swung upward to push and drive the push frame 3 to slide upward, and the left end portion of the driving shaft 107 is covered with a driven gear 1072; a rack 106 is slidably installed on the bottom of the top plate of the mounting base 1 through the pulling of a tension spring, and the rack 106 is meshed with the driven gear 1072 for transmission. The rack 106 can be meshed and driven by sliding backward to drive the driven gear 1072, the driving shaft 107 and the two push rods 1071 to swing upward.

[0035] Preferably,

[0036] Four vertical short sliding shafts are symmetrically welded between the two horizontal top shafts 301 and the Japanese-shaped force-bearing frame 302 , and the vertical short sliding shafts penetrate and slide with the bottom plate of the strip-shaped through groove 103 .

[0037] Preferably,

[0038] Two square sleeves 105 are welded and hoisted at a front-to-back interval on the bottom left side of the top plate of the mounting base 1. The rack 106 is arranged longitudinally and slides through the two square sleeves 105. The tension spring is hung between the rear end of the rear side sleeve 105 and the rack 106.

[0039] Embodiment 2, based on embodiment 1:

[0040] A swing rod 102 that can rotate horizontally left and right is installed on the left vertical support plate of the installation base 1.

[0041] The front end of the vertical support plate on the left side of the installation base 1 is provided with a strip through slot 103, and the front end part of the swing rod 102 swings through the strip through slot 103 and contacts the head end of the rack 106. The swing rod 102 is swung to the left to push and drive the rack 106 to slide backward, providing a lifting thrust for the push frame 3, and the swing rod 102 and the vertical positioning shaft 101 together form a lever mechanism. The part of the swing rod 102 located at the rear side of the vertical positioning shaft 101 is the power arm, and the part located at the front side of the vertical positioning shaft 101 is the resistance arm. The length of the power arm is much larger than the resistance arm, and the lever mechanism is a labor-saving lever. Through this labor-saving lever, the push frame 3 can be driven to slide up relatively easily, so that the lifting operation of the motor 2 is more labor-saving and convenient, and after the swing rod 102 is released, the push frame 3 is driven by the heavy pressure of the motor 2 to slide down and reset, driving the rack 106 to be pulled forward by the tension spring to reset and engage to drive the two push rods 1071 to rotate and swing down to reset;

[0042] When idle, the swing arm 102 is parallel to, fitted against, and retracted against the left vertical support plate of the mounting base 1 , to avoid long-term swinging and protruding, which would occupy additional support space and easily cause collision injuries to workers, thereby helping to improve the safety of the swing arm 102 .

[0043] Preferably,

[0044] The left and right vertical support plates of the mounting base 1 are both L-shaped structures, and a vertical positioning shaft 101 is welded to the front end portion of the left vertical support plate of the mounting base 1 .

[0045] Preferably,

[0046] The front end portion of the swing rod 102 is rotatably matched with the vertical positioning shaft 101 .

[0047] The working principle of this embodiment is as follows: when calibrating and aligning the bolt fixing holes and the bolt penetration holes, the push frame 3 can slide upward to push and separate the motor 2 and the mounting base 1, so that the fixing plate of the motor 2 is separated from the top horizontal surface of the mounting base 1, and the load is against the two horizontal top shafts 301, and the two horizontal top shafts 301 are adjusted by sliding. The two horizontal top shafts 301 are in a strip-shaped structure with a limited width and a small sliding contact area with the fixing plate of the motor 2, thereby reducing the friction resistance of the motor 2 in pushing activity;

[0048] Under normal conditions, the two horizontal top shafts 301 are inserted and hidden inside the two horizontal placement grooves 104, so that the top horizontal surface of the mounting base 1 remains flat, and the fixing plate of the motor 2 can be in contact with the top horizontal surface of the mounting base 1 over a large area as a whole, so that effective and stable installation and fixing can be implemented;

[0049] Through the two push rods 1071, the driving shaft 107 can swing upward to push and drive the pushing frame 3 to slide upward, and the rack 106 is meshed with the driven gear 1072 for transmission. The rack 106 slides backward to mesh and drive the driven gear 1072, the driving shaft 107 and the two push rods 1071 to swing upward. The swinging rod 102 to the left can push and drive the rack 106 to slide backward, providing an upward thrust for the pushing frame 3. After releasing the swing rod 102, the pushing frame 3 is driven by the heavy pressure of the motor 2 to slide down and reset, driving the rack 106 to be pulled forward by the tension spring to reset and mesh to drive the two push rods 1071 to rotate and swing down to reset.
