Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and in particular to a connection structure between an electrical cabinet body and a base. Background Art

[0002] An electrical cabinet is a cabinet made of steel materials to protect components from normal operation. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0003] In the related art, there is designed an electrical cabinet structure, which includes a base and a cabinet body. The base is used to be fixed on the ground. In some special environments, since a large number of electronic components are stored in the cabinet body and the overall structure of the cabinet body is heavy, it is necessary to pre-fix the base, use the lighter base for positioning, then use a hoisting device to lift the heavier cabinet body, and finally fix the cabinet body and the base with bolts, so as to quickly install the electrical cabinet at the required position.

[0004] In the process of implementing this application, it is found that there are at least the following problems in this technology: after pre-positioning the base, bolts are used to fix the cabinet body and the base. Therefore, one worker needs to hoist the cabinet body to adjust the direction of the cabinet body, and another worker operates tools to fix the cabinet body and the base. The construction steps are relatively cumbersome, the operation efficiency is low, and it is not convenient to quickly connect and fix the cabinet body and the base. Summary of the Invention

[0005] In order to reduce the construction difficulty, improve the operation efficiency, and quickly connect and fix the cabinet body and the base, this application provides a connection structure between an electrical cabinet body and a base.

[0006] The connection structure between an electrical cabinet body and a base provided by this application adopts the following technical solutions:

[0007] An electrical cabinet body and base connection structure, including a base and a cabinet body. An installation groove for inserting the cabinet body is provided on the surface of the base, and the inner wall of the installation groove is adapted to the outer wall of the cabinet body; several locking holes are symmetrically arranged on the inner wall of the installation groove, a locking sleeve is rotatably arranged in the locking hole, a locking rod is threadedly arranged in the locking sleeve, a limiting piece is fixedly arranged on the bottom wall of the locking hole, and the locking rod is slidably arranged on the limiting piece; sliding cavities are symmetrically arranged in the base, a sliding rack is slidably arranged in the sliding cavity, a locking gear is arranged on the outer wall of the locking sleeve, the sliding rack meshes with the locking gear, and a locking groove for inserting and abutting the locking rod is provided on the outer wall of the cabinet body; a driving cavity is arranged in the base, a driving member is arranged in the driving cavity, and the driving member is used to drive several sliding racks to slide simultaneously; a linkage member is arranged between the cabinet body and the base, and the linkage member is used to drive the driving member to work when the cabinet body is inserted into the installation groove.

[0008] By adopting the above technical solution, when installing the electrical cabinet, the base is pre-positioned and fixed on the ground, and then the staff uses a lifting tool to lift the cabinet body and insert the cabinet body into the installation groove in the vertical direction. At this time, the outer wall of the cabinet body is separated from the inner wall of the installation groove, and the installation groove can limit the rotation of the cabinet body. While the cabinet body is descending, the linkage member is inserted into the installation groove and drives the driving member to work. The driving member drives 4 sliding racks to slide simultaneously. The sliding rack abuts against several locking gears, thereby driving the locking sleeve to rotate. At the same time, the limiting piece guides the locking rod, so that the locking rod slides and contracts into the locking hole in the locking sleeve. Thus, the bottom end of the cabinet body can pass through the locking hole when descending; after the linkage member is separated from the driving member, the locking hole is exactly flush with the locking groove. The driving member then drives several sliding racks to slide in the reverse direction, thereby driving several locking gears to rotate in the reverse direction. The reverse rotation of the locking sleeve drives the locking rod to insert into the locking groove away from the locking hole, and the locking rod abuts against the inner wall of the locking groove, and the connection and fixation between the cabinet body and the base can be completed. The operation is convenient and fast. Only one staff member needs to operate the lifting tool to lift the cabinet body to complete the installation, which improves the operation efficiency.

[0009] Preferably, the driving member includes a connecting rope, a driving rope, a driving roller and a spring. The connecting rope is connected and fixed between adjacent sliding racks in the base. The spring is arranged in the sliding cavity and sleeved on the connecting rope. One end of the spring is connected to the sliding rack, and the other end of the spring is connected to the end wall of the sliding cavity; the driving roller is rotatably arranged in the driving cavity, one end of the driving rope is fixed to the surface of the driving roller, and the other end of the driving rope extends into the sliding cavity and is connected to the end wall of one of the sliding racks.

[0010] By adopting the above technical solution, after the cabinet body enters the installation groove, the linkage drives the driving roller to rotate. The driving roller pulls the driving rope to wind the driving rope on the surface of the driving roller. After the driving rope pulls one of the sliding racks to slide, the connecting rope drives several sliding racks to slide simultaneously, thereby driving several locking sleeves to rotate simultaneously, so that the locking rod contracts into the locking groove. At this time, the spring is compressed. After the linkage is separated from the driving member, under the action of the spring, the spring drives the sliding rack to slide in the reverse direction, thereby driving several locking sleeves to rotate in the reverse direction, so that the locking rod slides away from the locking groove and is inserted into the locking hole. The sliding rack abuts against the inner wall of the sliding cavity, driving the driving roller and the sliding rack to reset.

[0011] Preferably, the driving member further includes a guide wheel. A guide cavity is provided in the base. The guide wheel is rotatably arranged in the guide cavity. The connecting rope is wound around the guide wheel and abuts against the surface of the guide wheel.

[0012] By adopting the above technical solution, when the sliding rack slides, the connecting rope pulls the adjacent sliding rack. The connecting rope abuts against the surface of the guide wheel to drive the guide wheel to rotate. The guide wheel plays a guiding role for the connecting rope, which is beneficial to extending the service life of the driving member.

[0013] Preferably, the linkage includes a linkage rack, a linkage gear, a driving bevel gear and a driven bevel gear. The linkage rack is fixedly arranged at the bottom end of the side wall of the cabinet body. A linkage groove for inserting the linkage rack is formed in the inner wall of the installation groove. The linkage groove is communicated with the driving cavity. The linkage gear is rotatably arranged on the inner side wall of the driving cavity. The driving bevel gear is arranged on the end wall of the linkage gear. The driven bevel gear is fixedly arranged on the side wall of the driving roller. The driven bevel gear meshes with the driving bevel gear. The linkage rack can mesh with the linkage gear and can be separated from the linkage gear.

[0014] By adopting the above technical solution, when the cabinet body descends in the installation groove, the linkage rack is inserted into the linkage groove. After the linkage rack slides in the linkage groove, it will abut against the linkage gear. Therefore, when the cabinet body descends, it drives the linkage gear to rotate. The driving bevel gear on the linkage gear will abut against the driven bevel gear, thereby driving the driving roller to rotate, so that the locking rod automatically contracts into the locking groove. As the cabinet body descends, the linkage rack will be separated from the linkage gear. After separation, the spring drives the sliding rack to slide in the reverse direction to reset, thereby driving the locking rod away from the locking groove. When the locking groove is aligned with the locking hole, the locking rod automatically inserts into the locking groove.

[0015] Preferably, a notch is provided on the linkage gear. A separation groove communicated with the driving cavity is formed on the outer wall of the base. The linkage gear penetrates through the separation groove.

[0016] By adopting the above technical solution, when it is necessary to separately install different cabinets between the cabinet body and the base, the separation groove can be used to drive the linkage gear to rotate, and the notch on the linkage gear is rotated towards the direction of the linkage rack. Rotating the linkage gear can drive the driving roller to rotate and retract the locking rod into the locking groove. At the same time, with the notch facing the linkage rack, when the cabinet body is lifted, the linkage rack will not be limited by the linkage gear, thus realizing the separation between the cabinet body and the base.

[0017] Preferably, a plurality of abutting blocks are symmetrically arranged on the end wall of the linkage gear, and an abutting plate is slidably arranged on the outer side wall of the base, and the abutting block can abut against the abutting plate.

[0018] By adopting the above technical solution, when it is necessary to separate the cabinet body from the base, after rotating the linkage gear to drive the notch to rotate towards the direction of the linkage rack, the abutting plate is driven to slide, and the abutting plate is slid to one end of the abutting block. At this time, the linkage gear is released, and under the action of the spring, the abutting block can abut against the abutting plate, and the linkage gear cannot be reset and rotated, fixing the rotated linkage gear, so that it is not necessary to always hold the linkage gear forcefully when lifting the cabinet body, improving the operation convenience.

[0019] Preferably, convex stripes are integrally arranged on the inner wall of the notch.

[0020] By adopting the above technical solution, it is convenient to rotate the linkage gear.

[0021] Preferably, the end wall of the locking rod is arc-shaped.

[0022] By adopting the above technical solution, it plays a guiding role for the locking rod and facilitates the insertion of the locking rod into the locking hole.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By providing the installation groove, the locking hole, the locking sleeve, the locking rod, the limiting piece, the sliding cavity, the sliding rack, the locking gear, the locking groove, the driving cavity, the driving member and the linkage member, when installing the electrical cabinet, the base is pre-positioned and fixed on the ground. While the cabinet body is descending, the linkage member is inserted into the installation groove and drives the driving member to work. The driving member, the locking rod, slides and contracts in the locking sleeve into the locking hole. After the linkage member and the driving member are separated from each other, the locking hole is exactly flush with the locking groove. The driving member then drives a plurality of sliding racks to slide in the reverse direction at the same time, and further drives a plurality of locking rods to be inserted into the locking groove. The locking rod abuts against the inner wall of the locking groove, and the connection and fixation can be completed. The operation is convenient and fast. Only one person needs to operate the lifting tool to lift the cabinet body to complete the installation, improving the operation efficiency;

[0025] 2. By setting up a connecting rope, a driving rope, a driving roller, a spring and a guiding wheel, after the cabinet body enters the installation groove, the linkage drives the driving roller to rotate. The driving roller pulls the driving rope to wind around the surface of the driving roller. After the driving rope pulls one of the sliding racks to slide, the connecting rope drives several sliding racks to slide simultaneously, thereby driving several locking sleeves to rotate simultaneously, causing the locking rod to contract into the locking groove. At this time, the spring is compressed. After the linkage is separated from the driving part, under the action of the spring, the spring drives the sliding rack to slide reversely, thereby driving several locking sleeves to rotate in reverse, causing the locking rod to slide away from the locking groove and insert into the locking hole. The sliding rack abuts against the inner wall of the sliding cavity, driving the driving roller and the sliding rack to reset;

[0026] 3. By setting up a linkage rack, a linkage gear, a driving bevel gear and a driven bevel gear, when the cabinet body descends in the installation groove, the linkage rack is inserted into the linkage groove. After the linkage rack slides in the linkage groove, it will abut against the linkage gear. Therefore, when the cabinet body descends, it drives the linkage gear to rotate. The driving bevel gear on the linkage gear will abut against the driven bevel gear, thereby driving the driving roller to rotate, causing the locking rod to automatically contract into the locking groove; As the cabinet body descends, the linkage rack will be separated from the linkage gear. After separation, the spring drives the sliding rack to slide reversely and reset, thereby driving the locking rod away from the locking groove. When the locking groove is aligned with the locking hole, the locking rod automatically inserts into the locking groove. Description of the Drawings

Detailed implementation manners

[0033] The following will further describe the present application in detail with reference to the Figures 1-5 accompanying drawings.

[0034] An embodiment of the present application discloses a connection structure between an electrical cabinet body and a base. Referring to Figures 1 to 3 , its base 11 and cabinet body 12, a mounting groove 111 for inserting the cabinet body 12 is provided on the surface of the base 11. The base 11 is rectangularly arranged, and the inner wall of the mounting groove 111 is adapted to the outer wall of the cabinet body 12. A plurality of locking holes 2 are symmetrically arranged on the inner wall of the mounting groove 111. A locking sleeve 21 is rotatably arranged in the locking hole 2, and a locking rod 22 is threadedly arranged in the locking sleeve 21. A limiting piece 23 is fixedly arranged on the bottom wall of the locking hole 2. The cross section of the limiting piece 23 is rectangular, and the locking rod 22 is slidably arranged on the limiting piece 23. When the locking sleeve 21 rotates, the limiting piece 23 can prevent the self-rotation of the locking rod 22. The limiting piece 23 guides the locking rod 22 and can drive the locking rod 22 to slide along the length direction of the locking groove 121 in the locking sleeve 21.

[0035] Referring to Figures 3 to 5 , sliding cavities 3 are symmetrically arranged in the base 11. The length direction of the sliding cavities 3 is arranged along the length direction or width direction of the base 11. The sliding cavities 3 communicate with the locking holes 2. A sliding rack 31 is slidably arranged in the sliding cavity 3, and the sliding rack 31 is adapted to the sliding cavity 3. A locking gear 32 is fixedly arranged on the outer wall of the locking sleeve 21. The locking gear 32 is coaxially arranged with the locking sleeve 21. The sliding rack 31 meshes with a plurality of locking gears 32 in the sliding cavity 3 at the same time. The end wall of the locking rod 22 is arc-shaped. A locking groove 121 for inserting and abutting the locking rod 22 is provided on the outer wall of the cabinet body 12. The locking groove 121 is adapted to the locking rod 22. When the cabinet body 12 slides in the mounting groove 111 to a position where the locking hole 2 is flush with the locking groove 121, the locking rod 22 is inserted into the locking groove 121, and the locking rod 22 abuts against the inner wall of both the locking groove 121 and the locking hole 2 at the same time, so that the cabinet body 12 can be limited and fixed in the mounting groove 111.

[0036] Referring to Figure 4 andFigure 5 At the corner inside the base 11, a driving cavity 112 is provided, and a driving member 4 and a linkage member 5 are arranged in the driving cavity 112. The driving member 4 includes a connecting rope 41, a driving rope 42, a driving roller 43, a spring 44 and a guide pulley 45. The connecting rope 41 is connected and fixed between adjacent sliding racks 31 inside the base 11. A guide cavity is provided inside the base 11. The guide pulley 45 is rotatably arranged in the guide cavity. The connecting rope 41 is wound around the guide pulley 45 and abuts against the surface of the guide pulley 45. The spring 44 is arranged in the sliding cavity 3 and sleeved on the connecting rope 41. One end of the spring 44 is connected and abutted against the sliding rack 31, and the other end of the spring 44 is connected and abutted against the end wall of the sliding cavity 3. The driving roller 43 is rotatably arranged in the driving cavity 112. One end of the driving rope 42 is fixed to the surface of the driving roller 43, and the other end of the driving rope 42 extends into the sliding cavity 3 and is connected to the end wall of one of the sliding racks 31. When the cabinet body 12 enters into the installation groove 111, the linkage member 5 drives the driving roller 43 to rotate. The driving roller 43 pulls the driving rope 42 to drive the driving rope 42 to wind around the surface of the driving roller 43. After the driving rope 42 pulls one of the sliding racks 31 to slide, the guide pulley 45 rotates to guide the connecting rope 41, and the connecting rope 41 drives several sliding racks 31 to slide simultaneously, thereby driving several locking sleeves 21 to rotate simultaneously, so that the locking rod 22 contracts into the locking groove 121. At this time, the spring 44 is compressed; after the linkage member 5 and the driving member 4 are separated from each other, under the action of the spring 44, the spring 44 drives the sliding rack 31 to slide reversely, thereby driving several locking sleeves 21 to rotate reversely, so that the locking rod 22 automatically slides in the direction away from the locking groove 121 and is inserted into the locking hole 2. The sliding rack 31 abuts against the inner wall of the sliding cavity 3, driving the driving roller 43 and the sliding rack 31 to reset.

[0037] Refer to Figure 1 , Figure 4 and Figure 5, the linkage member 5 includes a linkage rack 51, a linkage gear 52, a driving bevel gear 53 and a driven bevel gear 54. The linkage rack 51 is fixedly arranged at the bottom end of the side wall of the cabinet body 12, and the length direction of the linkage rack 51 is arranged along the height direction of the cabinet body 12. A linkage groove 511 for inserting the linkage rack 51 is formed in the inner wall of the installation groove 111, and the linkage groove 511 is adapted to the linkage rack 51. The linkage groove 511 is communicated with the driving cavity 112. The linkage gear 52 is rotatably arranged on the inner side wall of the driving cavity 112. The driving bevel gear 53 is fixedly arranged on the end wall of the linkage gear 52, and the driving bevel gear 53 and the linkage gear 52 are coaxially arranged. The driven bevel gear 54 is fixedly arranged on the side wall of the driving roller 43, and the driven bevel gear 54 and the driving roller 43 are coaxially arranged. The driven bevel gear 54 meshes with the driving bevel gear 53. When the cabinet body 12 descends in the installation groove 111, the linkage rack 51 is inserted into the linkage groove 511. After the linkage rack 51 slides in the linkage groove 511, it will abut against the linkage gear 52. Therefore, when the cabinet body 12 descends, it drives the linkage gear 52 to rotate, and the driving bevel gear 53 on the linkage gear 52 will abut against the driven bevel gear 54, thereby driving the driving roller 43 to rotate, so that the locking rod 22 automatically retracts into the locking groove 121. As the cabinet body 12 descends, the linkage rack 51 will be disengaged from the linkage gear 52. After disengagement, the spring 44 drives the sliding rack 31 to slide reversely and reset, thereby driving the locking rod 22 away from the locking groove 121. When the locking groove 121 is aligned with the locking hole 2, without manual operation, the locking rod 22 automatically inserts into the locking groove 121.

[0038] Refer to Figure 1 and Figure 5, a notch 521 is provided on the linkage gear 52, and a convex rib 8 is integrally provided on the inner wall of the notch 521. A separation groove 6 communicating with the driving cavity 112 is formed on the outer wall of the base 11. The linkage gear 52 penetrates through the separation groove 6. A plurality of abutting blocks 7 are symmetrically arranged on the end wall of the linkage gear 52. An abutting plate 71 is slidably arranged on the outer side wall of the base 11 through a slide rail. When it is necessary to separate the cabinet body 12 from the base 11 and install different cabinet bodies 12, the convex rib 8 can be used to drive the linkage gear 52 in the separation groove 6 to rotate, and the notch 521 on the linkage gear 52 is rotated towards the direction of the linkage rack 51. Rotating the linkage gear 52 can make the driving roller 43 rotate to drive the locking rod 22 to retract into the locking groove 121, and at the same time make the notch 521 face the linkage rack 51, so that when the cabinet body 12 is lifted, the linkage rack 51 will not be limited by the linkage gear 52; after rotating the linkage gear 52 to drive the notch 521 to rotate towards the direction of the linkage rack 51, the abutting plate 71 is driven to slide, and the abutting plate 71 is slid to one end of the abutting block 7. At this time, the linkage gear 52 is released. Under the action of the spring 44, the abutting block 7 can abut against the abutting plate 71, and the linkage gear 52 cannot be reset and rotated, fixing the rotated linkage gear 52, so that there is no need to always support the linkage gear 52, and the cabinet body 12 can be directly lifted by a lifting tool to quickly separate the cabinet body 12 from the installation groove 111.

[0039] The implementation principle of the connection structure between the electrical cabinet body and the base in the embodiment of the present application is as follows: When installing the electrical cabinet, the base 11 is pre-positioned and fixed on the ground. Then, the staff uses a hoisting tool to lift the cabinet body 12 and insert the cabinet body 12 vertically into the installation groove 111. At this time, the outer wall of the cabinet body 12 is separated from the inner wall of the installation groove 111. The installation groove 111 can limit the rotation of the cabinet body 12. While the cabinet body 12 is descending, the linkage rack 51 is inserted into the linkage groove 511. The linkage rack 51 drives the linkage gear 52 and the driving bevel gear 53 to rotate. The driving bevel gear 53 then drives the driven bevel gear 54 and the driving roller 43 to rotate. The driving roller 43 pulls the driving rope 42 to drive the driving rope 42 to wind on the surface of the driving roller 43. After one of the sliding racks 31 slides under the pull of the driving rope 42, the connecting rope 41 drives several sliding racks 31 to slide simultaneously. The spring 44 is compressed. The sliding rack 31 and the locking gear 32 are simultaneously abutted, thereby driving the locking sleeve 21 to rotate. At the same time, the limiting piece 23 guides the locking rod 22, so that the locking rod 22 slides and contracts into the locking hole 2 in the locking sleeve 21. Thus, the bottom end of the cabinet body 12 can pass through the locking hole 2 when descending. As the cabinet body 12 descends, the linkage rack 51 will be separated from the linkage gear 52. After separation, the spring 44 drives the sliding rack 31 to slide reversely and reset, thereby driving the locking rod 22 away from the locking groove 121. When the locking groove 121 is aligned with the locking hole 2, the locking rod 22 automatically inserts into the locking groove 121. The locking rod 22 abuts against the inner wall of the locking groove 121, and the connection and fixation between the cabinet body 12 and the base 11 can be completed. The operation is convenient and fast. Only one staff member needs to operate the hoisting tool to hoist the cabinet body 12 to complete the installation, improving the operation efficiency.

[0040] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
