Description

Technical Field

[0001] This invention relates to the technical field of equipment bases, and in particular to a rotatable power equipment mounting base. Background Technology

[0002] Electrical equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc., while power supply equipment mainly includes transmission lines of various voltage levels, instrument transformers, contactors, etc. Power equipment mounting bases are platforms used to support and fix electrical equipment, making it more stable during installation. However, existing power equipment mounting bases are generally rectangular frames, which may make it inconvenient to rotate and adjust the position of the electrical equipment after installation.

[0003] Utility model CN213629599U discloses a rotatable power equipment mounting base, including support components. Four sets of support components have a base at their upper ends. A drive mechanism is located within the inner cavity of the base. The drive mechanism includes a drive motor and a rotating shaft. The drive motor is fixedly installed within the inner cavity of the base. A main synchronous pulley is located at the output end of the drive motor. The rotating shaft is rotatably positioned within the inner cavity of the base, and a secondary synchronous pulley is located at its lower end. This utility model has a simple structure. Under the action of the drive mechanism, it enables rapid and convenient rotation of the mounting plate, facilitating the adjustment of the installation angle of the power equipment and improving the flexibility of its use. Furthermore, the shock-absorbing device reduces the vibration generated during the operation of the power equipment, thereby reducing the force between the power equipment, the base, and the drive mechanism, and ensuring the normal operation of the power equipment and the drive mechanism.

[0004] In the above-mentioned technical solution, an array of mounting components is fixedly installed on the upper end of the mounting plate. The position of the power equipment can be fixed by the fixed mounting components. However, the position of the mounting components set in the above solution is relatively fixed, while the position of the mounting holes opened on the bottom of different models of power equipment may be different. Therefore, the above solution may not be convenient to use for different models of power equipment. Therefore, those skilled in the art have provided a rotatable power equipment fixing base to solve the problems mentioned in the background art. Summary of the Invention

[0005] To address the issue that while an array of mounting components can be fixedly installed on the upper part of a mounting plate to secure the position of electrical equipment, the positions of these components are relatively fixed. However, the mounting holes on the bottom of different models of electrical equipment may have different positions, making it inconvenient to use with different models of electrical equipment. Therefore, this invention provides a rotatable electrical equipment fixing base.

[0006] The rotatable power equipment mounting base provided in this application adopts the following technical solution: A rotatable power equipment mounting base includes a supporting base plate. A connecting mechanism is fixedly connected to the upper surface of the supporting base plate. A first bevel gear is movably connected inside the connecting mechanism. A connecting column is fixedly connected to the upper surface of the first bevel gear. A mounting plate is fixedly connected to the upper surface of the connecting column. A transmission mechanism is movably connected inside the mounting plate. An adjusting mechanism is symmetrically engaged with the outer wall of the transmission mechanism. Both ends of the adjusting mechanism are rotatably connected to the inner wall of the mounting plate. Mounting components are symmetrically threaded to the outer wall of the adjusting mechanism. The outer wall of the mounting components is slidably connected to the inner wall of the mounting plate. A butterfly adjusting bolt is rotatably connected to one side of the connecting mechanism. One end of the butterfly adjusting bolt passes through the connecting mechanism and is fixedly connected to a second bevel gear. The outer wall of the second bevel gear meshes with the outer wall of the first bevel gear.

[0007] By adopting the above technical solution, the transmission mechanism can simultaneously drive the symmetrically arranged adjustment mechanism to rotate when it rotates. When the adjustment mechanism rotates, it can simultaneously control the symmetrically arranged mounting parts to move towards each other, so that the position of the mounting parts can be adjusted according to the position of the mounting hole opened on the actual installed power equipment. When the butterfly adjustment bolt is rotated by personnel, it can control the first bevel gear to rotate through the second bevel gear, thereby driving the installed power equipment to rotate through the rotation of the first bevel gear.

[0008] Preferably, the supporting base plate includes a first rectangular plate fixedly connected to the lower surface of the connecting mechanism, the first rectangular plate having uniformly spaced limiting holes through which the first rectangular plate passes, and a first anti-slip pad fixedly connected to the lower surface of the first rectangular plate.

[0009] By adopting the above technical solution, the limiting hole, in conjunction with the bolt, can restrict the position of the first rectangular plate, and the first anti-slip pad can increase the friction between the first rectangular plate and the mounting surface when the first rectangular plate is installed.

[0010] Preferably, the mounting plate includes a second rectangular plate fixedly connected to the upper surface of the connecting column, the outer wall of the transmission mechanism is rotatably connected to the inner wall of the second rectangular plate, a second anti-slip pad is fixedly connected to the upper surface of the second rectangular plate, and symmetrical grooves are formed on the upper surface of the second rectangular plate. The adjusting mechanism and the mounting component are both located inside the grooves.

[0011] By adopting the above technical solution, the second anti-slip pad can increase the friction between itself and the bottom of the power equipment when fixing the power equipment. The sliding groove can limit the installation position of the adjustment mechanism and also limit the movement position of the installation parts.

[0012] Preferably, the connecting mechanism includes a cylindrical part fixedly connected to the upper surface of the first rectangular plate. The lower surface of the cylindrical part is provided with a storage groove. The first bevel gear and the second bevel gear are both located inside the storage groove.

The connecting column passes through the interior of the connecting groove. The outer diameter of the connecting column matches the inner diameter of the connecting groove.

[0013] By adopting the above technical solution, the storage slot can restrict the installation position of the first bevel gear and the second bevel gear, and the connecting slot can restrict the installation position of the connecting column.

[0014] Preferably, the lower surface of the first bevel gear is provided with uniformly distributed storage holes, and the bottom of the first bevel gear is uniformly and movably connected with ball bearings located inside the storage holes, with the side of the ball bearings away from the storage holes abutting against the upper surface of the first rectangular plate.

[0015] By adopting the above technical solution, the ball bearings can reduce the friction between themselves and the first rectangular plate when the first bevel gear rotates.

[0016] Preferably, the transmission mechanism includes a butterfly-shaped adjusting head located on one side of the second rectangular plate, a shaft fixedly connected to one side of the butterfly-shaped adjusting head, the outer wall of the shaft being rotatably connected to the inner wall of the second rectangular plate, and a worm gear symmetrically fixedly connected to the outer wall of the shaft, the outer wall of the worm gear meshing with the outer wall of the adjusting mechanism.

[0017] By adopting the above technical solution, the butterfly-shaped adjusting head can drive the worm gear to rotate through the shaft when the operator rotates, and the rotation of the worm gear can control the rotation of the adjusting mechanism.

[0018] Preferably, an annular scale is fixedly connected to the upper surface of the cylindrical part, and an adjustment indicator is fixedly connected to the outer wall of the connecting column, with the adjustment indicator located on the upper surface of the annular scale.

[0019] By adopting the above technical solution, the ring scale, in conjunction with the adjusting indicator needle, allows personnel to easily observe the rotation position of the connecting column when it rotates.

[0020] Preferably, the adjusting mechanism includes a reverse threaded rod located inside the slide groove, the two ends of the reverse threaded rod having reversed external thread teeth, the outer wall of the reverse threaded rod being threadedly connected to the inner wall of the mounting component, and a turbine being fixedly connected to the outer wall of the reverse threaded rod, the outer wall of the turbine meshing with the outer wall of the worm gear.

[0021] By adopting the above technical solution, the reverse threaded rod can rotate under the cooperation of the worm gear and the worm, and when the reverse threaded rod rotates, the symmetrically arranged mounting parts can be moved towards each other at the same time.

[0022] Preferably, the mounting component includes a movable block threadedly connected to the outer wall of the reverse threaded rod, the movable block being located inside the slide groove, and a threaded mounting bolt being fixedly connected to the upper surface of the movable block.

[0023] By adopting the above technical solution, the moving block can move when the reverse threaded rod rotates, thereby adjusting the position of the threaded mounting bolt according to the position of the mounting hole opened on the power equipment.

[0024] In summary, the present invention has the following beneficial technical effects: 1.

When the adjustment mechanism rotates, it can simultaneously control the symmetrically arranged mounting parts to move towards each other, so that the position of the mounting parts can be adjusted according to the position of the mounting hole opened on the actual installed power equipment. This allows the present application to match different models of power equipment for installation and use as much as possible.

The rotation of the worm gear controls the rotation of the adjusting mechanism. The reverse threaded rod can rotate in cooperation with the worm gear. When the reverse threaded rod rotates, it can simultaneously control the symmetrically arranged moving blocks to move in opposite directions, thereby adjusting the position of the threaded mounting bolt according to the position of the mounting hole opened on the power equipment.

[0026] 3. The rotatable power equipment fixing base is equipped with ball bearings that reduce the friction between the ball bearings and the first rectangular plate when the first bevel gear rotates. The ring scale, in conjunction with the adjusting indicator needle, allows personnel to easily observe the rotation position of the connecting column when it rotates. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below. Example 1

[0030] This invention discloses a rotatable mounting base for electrical equipment. (Refer to...) Figure 1 , Figure 2 and Figure 3The rotatable power equipment mounting base includes a support base plate 1. A connecting mechanism 2 is fixedly connected to the upper surface of the support base plate 1. A first bevel gear 3 is movably connected inside the connecting mechanism 2. A connecting column 4 is fixedly connected to the upper surface of the first bevel gear 3. A mounting plate 5 is fixedly connected to the upper surface of the connecting column 4.

The outer wall of the mounting parts 10 is slidably connected to the inner wall of the mounting plate 5. A butterfly adjusting bolt 6 is rotatably connected to one side of the connecting mechanism 2. One end of the butterfly adjusting bolt 6 passes through the connecting mechanism 2 and is fixedly connected to a second bevel gear 7.

[0031] In this embodiment, the support base plate 1 in the rotatable power equipment fixing base can limit the installation position of the connecting mechanism 2. The connecting mechanism 2 can limit the installation position of the first bevel gear 3 and the connecting column 4. The connecting column 4 can limit the installation position of the mounting plate 5. The mounting plate 5 can support the power equipment that needs to be fixed and limited. When the transmission mechanism 8 rotates, it can simultaneously drive the symmetrically arranged adjustment mechanism 9 to rotate. When the adjustment mechanism 9 rotates, it can simultaneously control the symmetrically arranged mounting parts 10 to move towards each other, so that the position of the mounting parts 10 can be adjusted according to the position of the mounting hole opened on the actual installed power equipment. This allows the present application to match different models of power equipment for installation and use as much as possible. When the butterfly adjusting bolt 6 is rotated by personnel, it can drive the second bevel gear 7 to rotate. When the second bevel gear 7 rotates, it can control the first bevel gear 3 that meshes with it to rotate. Thus, through the rotation of the first bevel gear 3, the installed power equipment can be driven to rotate, which can enhance the practicality of the present application.

[0032] In a further preferred embodiment of the invention, such as Figure 1 and Figure 2 As shown, the support base plate 1 includes a first rectangular plate 101 fixedly connected to the lower surface of the connecting mechanism 2. The first rectangular plate 101 has uniformly opened limiting holes 102 through which the first rectangular plate 101 passes. A first anti-slip pad 103 is fixedly connected to the lower surface of the first rectangular plate 101.

[0033] In this embodiment, the first rectangular plate 101 can limit the installation position of the connecting mechanism 2. The limiting hole 102, in conjunction with the bolt, can limit the position of the first rectangular plate 101. The first anti-slip pad 103 can increase the friction between the first rectangular plate 101 and the mounting surface when the first rectangular plate 101 is installed.

[0034] In a further preferred embodiment of the invention, such as Figure 2 and Figure 3 As shown, the connecting mechanism 2 includes a cylindrical part 201 fixedly connected to the upper surface of the first rectangular plate 101.

[0035] In this embodiment, the storage slot 202 can restrict the installation position of the first bevel gear 3 and the second bevel gear 7, and the connecting slot 203 can restrict the installation position of the connecting column 4, while facilitating the rotation of the connecting column 4.

[0036] In a further preferred embodiment of the invention, such as Figure 1 , Figure 2 and Figure 4 As shown, the mounting plate 5 includes a second rectangular plate 501 fixedly connected to the upper surface of the connecting column 4. The outer wall of the transmission mechanism 8 is rotatably connected to the inner wall of the second rectangular plate 501. A second anti-slip pad 15 is fixedly connected to the upper surface of the second rectangular plate 501. Slide grooves 502 are symmetrically opened on the upper surface of the second rectangular plate 501. The adjusting mechanism 9 and the mounting component 10 are both located inside the slide grooves 502.

[0037] In this embodiment, the second rectangular plate 501 can provide some support for the fixed power equipment. When the second anti-slip pad 15 is used to fix the power equipment, it can increase the friction between the pad and the bottom of the power equipment. The groove 502 can restrict the installation position of the adjustment mechanism 9 and also restrict the movement position of the mounting part 10.

[0038] In a further preferred embodiment of the invention, such as Figure 2 and Figure 4 As shown, the transmission mechanism 8 includes a butterfly adjusting head 801 located on one side of the second rectangular plate 501. A shaft 802 is fixedly connected to one side of the butterfly adjusting head 801. The outer wall of the shaft 802 is rotatably connected to the inner wall of the second rectangular plate 501. A worm gear 803 is symmetrically fixedly connected to the outer wall of the shaft 802. The outer wall of the worm gear 803 meshes with the outer wall of the adjusting mechanism 9.

[0039] In this embodiment, when the butterfly-shaped adjusting head 801 is rotated by the operator, it can drive the shaft 802 to rotate. When the shaft 802 rotates, it can drive the worm gear 803 to rotate. The rotation of the worm gear 803 can control the adjustment mechanism 9 to rotate.

[0040] In a further preferred embodiment of the invention, such as Figure 2 , Figure 3 and Figure 4 As shown, the adjusting mechanism 9 includes a reverse threaded rod 901 located inside the slide groove 502. The external threads at both ends of the reverse threaded rod 901 are arranged in opposite directions. The outer wall of the reverse threaded rod 901 is threadedly connected to the inner wall of the mounting part 10. A turbine 902 is fixedly connected to the outer wall of the reverse threaded rod 901. The outer wall of the turbine 902 meshes with the outer wall of the worm gear 803.

[0041] In this embodiment, the reverse threaded rod 901 can rotate with the cooperation of the turbine 902 and the worm gear 803. When the reverse threaded rod 901 rotates, it can simultaneously control the symmetrically arranged mounting parts 10 to move towards each other.

[0042] In a further preferred embodiment of the invention, such as Figure 2 , Figure 3 and Figure 4 As shown, the mounting component 10 includes a movable block 1001 that is threadedly connected to the outer wall of the reverse threaded rod 901. The movable block 1001 is located inside the slide groove 502, and a threaded mounting bolt 1002 is fixedly connected to the upper surface of the movable block 1001.

[0043] In this embodiment, the movable block 1001 can move when the reverse threaded rod 901 rotates, thereby adjusting the position of the threaded mounting bolt 1002 according to the position of the mounting hole opened on the power equipment. The threaded mounting bolt 1002, by cooperating with the nut, can restrict the installation position of the power equipment. Example 2

[0044] This embodiment is an improvement based on Embodiment 1, please refer to the following for details. Figure 5 As shown, the lower surface of the first bevel gear 3 is uniformly provided with storage holes 11, and the bottom of the first bevel gear 3 is uniformly movably connected with ball bearings 12 located inside the storage holes 11. The side of the ball bearings 12 away from the storage holes 11 abuts against the upper surface of the first rectangular plate 101.

[0045] In this embodiment, the opening of the storage hole 11 can restrict the installation position of the ball 12, and the ball 12 can reduce the friction between itself and the first rectangular plate 101 when the first bevel gear 3 rotates.

[0046] In a further preferred embodiment of the invention, such as Figure 1 and Figure 2 As shown, an annular scale 13 is fixedly connected to the upper surface of the cylindrical part 201, and an adjustment indicator 14 is fixedly connected to the outer wall of the connecting column 4. The adjustment indicator 14 is located on the upper surface of the annular scale 13.

[0047] In this embodiment, the annular scale 13, in conjunction with the adjustment indicator 14, allows personnel to easily observe the rotation position of the connecting column 4 when it rotates.

[0048] The implementation principle of the rotatable power equipment fixing base of this invention is as follows: In use, the operator rotates the transmission mechanism 8 to simultaneously drive the symmetrically arranged adjustment mechanism 9 to rotate. When the adjustment mechanism 9 rotates, it can simultaneously control the symmetrically arranged mounting parts 10 to move towards each other, so that the position of the mounting parts 10 can be adjusted according to the position of the mounting holes opened on the actual installed power equipment. This allows the application to be matched with different models of power equipment for installation and use as much as possible. By rotating the butterfly-shaped adjustment bolt 6, the second bevel gear 7 can be driven to rotate. When the second bevel gear 7 rotates, it can control the first bevel gear 3 to rotate. Thus, when the first bevel gear 3 rotates, it can control the rotation of the installed power equipment through the cooperation of the connecting column 4 and the mounting plate 5, making the application more conducive to practical use. The butterfly-shaped adjusting head 801 rotates via the shaft 802, driving the worm gear 803 to rotate. The rotation of the worm gear 803 controls the rotation of the turbine 902. The reverse threaded rod 901 rotates in cooperation with the turbine 902 and the worm gear 803. When the reverse threaded rod 901 rotates, it can simultaneously control the symmetrically arranged moving blocks 1001 to move in opposite directions, thereby adjusting the position of the threaded mounting bolt 1002 according to the position of the mounting hole opened on the power equipment. The ball bearing 12 is located at the bottom of the first bevel gear 3. When the first bevel gear 3 rotates, the ball bearing 12 can reduce the friction between it and the first rectangular plate 101. The upper surface of the cylindrical part 201 is fixedly connected to an annular scale 13. The annular scale 13 cooperates with the adjusting indicator needle 14, making it easy for personnel to observe the rotation position of the connecting column 4 when it rotates.

[0049] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
