Description

Technical Field

[0001] The present invention relates to the technical field of building mechanical and electrical installation, and particularly relates to an installation device for mechanical and electrical equipment. Background Art

[0002] In green building projects, the prefabrication method is usually adopted for the installation of mechanical and electrical equipment to achieve the effects of improving installation efficiency and reducing construction time. During installation, a lifting platform is usually required to move and transport building mechanical and electrical equipment to a designated height position, and then on-site assembly is carried out, such as the installation of equipment such as air conditioners, so as to avoid the safety risks existing when manually handling mechanical and electrical equipment. Compared with the traditional method of using escalators for the installation of mechanical and electrical equipment, it can improve the work efficiency and quality, and ensure the convenience of the installation of mechanical and electrical facilities.

[0003] However, the existing lifting platform device for installing mechanical and electrical equipment cannot perform an all-round clamping protection on the periphery of mechanical and electrical equipment with different sizes, which causes the corners of the periphery of mechanical and electrical equipment to easily touch external objects, which obviously reduces the protection effect of the installation device on mechanical and electrical equipment and there are potential safety hazards and installation risks.

[0004] Therefore, there is an urgent need for an installation device for mechanical and electrical equipment to solve the problem that the existing lifting platform device for installing mechanical and electrical equipment has a poor protection effect on the corners of the periphery of mechanical and electrical equipment. Summary of the Invention

[0005] Aiming at the deficiencies in the prior art, the present invention provides an installation device for mechanical and electrical equipment to solve the problem that the existing lifting platform device for installing mechanical and electrical equipment has a poor protection effect on the corners of the periphery of mechanical and electrical equipment.

[0006] To achieve the above object, the present invention adopts the following technical solutions: An installation device for mechanical and electrical equipment, characterized in that it includes a scissor lift, a support plate, a limit seat, a first positioning ring, a second positioning ring, a first threaded rod, a movable seat, a driving structure, a first clamping plate and a second clamping plate. The support plate is fixedly installed on the movable end of the scissor lift. A limit seat is provided in the middle of the upper end of the support plate. The first positioning ring and the second positioning ring are rotatably stacked up and down around the limit seat. On both sides of the periphery of the first positioning ring and the second positioning ring, a first threaded rod is symmetrically and rotatably connected in a direction away from the limit seat. A movable seat is symmetrically threadedly connected to each first threaded rod. A first clamping plate is rotatably installed at the upper end of each movable seat. A rectangular columnar installation groove is provided on the first clamping plate. The installation grooves of the four first clamping plates can be spliced into a complete and connected rectangular groove. A second clamping plate is slidably inserted and installed in the adjacent side walls of the adjacent first clamping plates. The driving structure is used to drive each first threaded rod to rotate synchronously.

[0007] To optimize the above technical solution, the specific measures taken also include: Further, the driving structure includes a driving motor, a bevel gear ring, and a driving gear. A bevel gear ring coaxial with the limiting seat is rotatably installed at the upper end of the support plate. A bevel gear for meshing with the inner tooth ring of the bevel gear ring is fixedly installed at the outer end of each first threaded rod away from the limiting seat. A driving motor is also fixedly installed on the support plate, and a driving gear for meshing with the outer tooth ring of the bevel gear ring is fixedly installed on the output shaft of the driving motor.

[0008] Further, limiting slide rails are fixedly installed on the sides of the first positioning ring and the second positioning ring. The movable seat is correspondingly slidably arranged around the limiting slide rails. A first threaded rod threadedly connected to the movable seat is rotatably installed inside the limiting slide rails.

[0009] Further, limiting rotating seats are fixedly installed at both ends of each limiting slide rail. The first threaded rod is rotatably installed between the two limiting rotating seats. A limiting slide hole is formed in the movable seat, and the movable seat is slidably connected to the limiting slide rail through the limiting slide hole.

[0010] Further, a positioning toothed plate is also included. Positioning tooth cavities that are coaxial and identical are respectively formed in the middle parts of the first positioning ring and the second positioning ring. The positioning toothed plate is used to penetrate and be inserted into the two positioning tooth cavities when the first positioning ring and the second positioning ring rotate relative to each other until the two positioning tooth cavities coincide.

[0011] Further, a through hole is formed in the middle of the positioning toothed plate. A vertical limiting shaft is arranged in the middle of the limiting seat. A vertical limiting chute is formed in the side wall of the limiting shaft. The positioning toothed plate is sleeved outside the limiting shaft through the through hole in the middle and can move up and down. A limiting slide rod slidably connected to the limiting chute is arranged on the inner side of the positioning toothed plate. A rotating block is rotatably installed in the middle of the limiting shaft. The rotating block is located inside the limiting shaft, and a threaded curve groove is formed in the side wall corresponding to the limiting chute. The inner end of the limiting slide rod extends and is slidably installed in the threaded curve groove. The rotating block is used to rotate and drive the positioning toothed plate to slide up and down along the limiting chute.

[0012] Further, the upper end of the rotating block extends out of the upper end of the limiting shaft, and a circular driving knob is provided.

[0013] Further, the lower end of the limiting seat is inserted into the upper end of the support plate through two vertical insertion rods and can move up and down.

[0014] Further, a threaded hole is formed in the middle of the upper end of the support plate. A second threaded rod for threadedly connecting with the threaded hole is rotatably installed in the middle of the limiting seat. The upper end of the second threaded rod extends out of the limiting seat.

[0015] Furthermore, the scissor-type lift array is provided with movable or lockable universal wheels.

[0016] The beneficial effects of the present invention are: When the present invention is in use, the relative positions of the first positioning ring and the second positioning ring can be rotated on the periphery of the limit seat according to the size or shape of the building electromechanical equipment, so that the ratio of the distance between adjacent first clamping plates is equal to the length-width ratio of the periphery of the electromechanical equipment to conform to the shape of the electromechanical equipment, and then the driving structure drives each first threaded rod to rotate synchronously, and drives the movable seat to carry each first clamping plate to perform proportional scaling movement, so that the first clamping plate and the second clamping plate fit and protect the outside of the electromechanical equipment; at the same time, by sliding the second clamping plate installed between adjacent first clamping plates, a full-coverage clamping protection can be performed on the periphery of the electromechanical equipment, thereby increasing the completeness and protection of the electromechanical equipment during movement; by the rotational connection between each movable seat and the first clamping plate, the first clamping plate and the second clamping plate can be easily adjusted to different shapes; by setting the first clamping plate with a rectangular columnar mounting groove, each first clamping plate can fit the corner of the periphery of the building electromechanical equipment, so that the first clamping plate can position and protect the corner of the periphery of the building electromechanical equipment, thereby improving the clamping and positioning effect of the device on the building electromechanical equipment.

[0017] When the present invention is in use, the rotating block can be rotated as needed. Due to the connection between the threaded curved groove on the rotating block and the limiting slide rod, the limiting slide rod can drive the positioning tooth plate to move upward along the limiting slide groove to disengage from the positioning tooth cavity, thereby releasing the restriction effect on the first positioning ring and the second positioning ring, facilitating the rotation of the first positioning ring and the second positioning ring, so that the ratio of the distance between adjacent first clamping plates is equal to the length-to-width ratio of the building's mechanical and electrical periphery; thereafter, the rotating block is rotated in the opposite direction until the positioning tooth plate moves downward along the limiting slide groove to be reinserted into the positioning tooth cavity, thereby conveniently achieving the effect of positioning the relative positions of the first positioning ring and the second positioning ring.

Detailed description of the specific implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] As shown in Figure 1 and Figure 2 and Figure 3 , an electromechanical installation device according to an embodiment of the present invention includes a scissor lift 1, a support plate 11, a limit seat 4, a first positioning ring 41, a second positioning ring 42, a first threaded rod 31, a movable seat 3, a drive structure, a first clamping plate 2 and a second clamping plate 22. The support plate 11 is fixedly installed on the movable end of the scissor lift 1. The scissor lift 1 is used to drive the support plate 11 to move up and down. A limit seat 4 is provided in the middle of the upper end of the support plate 11. The first positioning ring 41 and the second positioning ring 42 are rotatably stacked on the periphery of the limit seat 4 up and down. The two sides of the first positioning ring 41 and the second positioning ring 42 that are offset from each other are symmetrically connected with a first threaded rod 31 rotatably away from the limit seat 4. Each first threaded rod 31 is symmetrically threadedly connected with a movable seat 3. A first clamping plate 2 is rotatably installed at the upper end of each movable seat 3. A rectangular columnar installation groove is provided on the first clamping plate 2. The installation grooves of the four first clamping plates 2 can move along the corresponding first threaded rods 31 and are spliced into a complete and connected rectangular groove. A second clamping plate 22 is slidably inserted and installed in the adjacent side walls of the adjacent first clamping plates 2. The drive structure is used to drive each first threaded rod 31 to rotate synchronously.

[0022] When the present invention is in use, according to the size or shape of the building mechanical and electrical equipment, the relative position of the first positioning ring 41 and the second positioning ring 42 can be rotated around the periphery of the limit seat 4, so that the ratio of the distance between adjacent first clamping plates 2 is equal to the aspect ratio of the length and width of the periphery of the mechanical and electrical equipment, to conform to the shape of the mechanical and electrical equipment. Then, the driving structure is used to drive each first threaded rod 31 to rotate synchronously, and drive the movable seat 3 to drive the respective first clamping plates 2 to perform an equal-proportion scaling movement, so that the first clamping plates 2 and the second clamping plates 22 are attached and protected on the outer side of the mechanical and electrical equipment. At the same time, the second clamping plates 22 slidably inserted between adjacent first clamping plates 2 can provide a full-wrap clamping protection for the periphery of the mechanical and electrical equipment, increasing the integrity and protection during the movement of the mechanical and electrical equipment. Through the rotational connection between each movable seat 3 and the first clamping plate 2, it is convenient to adjust the first clamping plate 2 and the second clamping plate 22 to different forms. Through the arrangement of the first clamping plate 2 with a rectangular columnar installation groove, each first clamping plate 2 can be attached to the corners of the periphery of the building mechanical and electrical equipment, enabling the first clamping plate 2 to position and protect the corners of the periphery of the building mechanical and electrical equipment.

[0023] In this solution, the above-mentioned first clamping plate 2 is rotatably connected to the upper end of the movable seat 3 through the supporting plate 21 at the bottom, and the supporting plate 21 can support the bottom of the building mechanical and electrical equipment. In this solution, the above-mentioned first threaded rods 31 and the movable seats 3 threadedly connected thereto are symmetrically distributed along the diagonals of the rectangle respectively. In this solution, the ends of the above-mentioned second clamping plates 22 for slidably inserting into the side walls of the first clamping plates 2 are all provided with limit blocks, and the side walls of the first clamping plates 2 are provided with slots for the second clamping plates 22 and the limit blocks to slidably insert, and the opening of the slot is a reduced opening to prevent the limit blocks from slipping off. In this solution, the first positioning ring 41 is rotatably arranged around the periphery of the limit seat 4, and the second positioning ring 42 is rotatably stacked on the upper end of the first positioning ring 41.

[0024] As shown in the attached Figure 4 figure, in another specific embodiment based on the above, the driving structure includes a driving motor 33, a bevel gear ring 34 and a driving gear 35. The upper end of the support plate 11 is rotatably installed with a bevel gear ring 34 coaxial with the limit seat 4. Each outer end of the first threaded rod 31 away from the limit seat 4 is fixedly installed with a bevel gear 32 for meshing connection with the inner gear ring of the bevel gear ring 34. The support plate 11 is also fixedly installed with a driving motor 33, and the output shaft of the driving motor 33 is fixedly installed with a driving gear 35 for meshing connection with the outer gear ring of the bevel gear ring 34. The driving gear 35 is used to drive the bevel gear ring 34 to drive the bevel gear ring 34 to rotate, and then the bevel gear ring 34 correspondingly drives the first threaded rod 31 to rotate.

[0025] Therefore, during use, the drive motor 33 can be started as needed, and the drive gear 35 thereon is driven by the output shaft to rotate forward and backward, thereby driving the bevel gear ring 34 meshing with the drive gear 35 to rotate, and using the rotation of the bevel gear ring 34 to synchronously drive the four bevel gears 32 meshing with it to rotate synchronously, so as to realize the synchronous rotation of the four first threaded rods 31. Finally, due to the threaded connection between the first threaded rod 31 and the movable seat 3, the contraction and expansion between the first clamping plate 2 and the second clamping plate 22 are driven until the first clamping plate 2 and the second clamping plate 22 contact the outside of the building electrical and mechanical equipment, achieving the positioning effect on the building electrical and mechanical equipment.

[0026] In another specific embodiment based on the above, limit sliding rails 37 are fixedly installed on the sides of the first positioning ring 41 and the second positioning ring 42. The movable seat 3 is correspondingly slidably arranged around the limit sliding rails 37, and a first threaded rod 31 threadedly connected to the movable seat 3 is rotatably installed inside the limit sliding rails 37.

[0027] As shown in the attached Figure 5 figure, wherein, limit rotating seats 36 are fixedly installed at both ends of each limit sliding rail 37. The first threaded rod 31 is rotatably installed between the two limit rotating seats 36, and a limit sliding hole 38 is formed in the movable seat 3 and is slidably connected to the limit sliding rail 37 through the limit sliding hole 38.

[0028] Therefore, by setting the limit rotating seat 36, the movement direction of the first threaded rod 31 can be restricted. By setting the limit sliding hole 38 and its sliding connection with the limit sliding rail 37, the movement directions of the respective movable seats 3 can be restricted.

[0029] As shown in the attached Figure 6 and the attached Figure 7 figure, in another specific embodiment based on the above, a positioning toothed plate 43 is further included. Coaxial and identical positioning tooth cavities 39 are respectively formed in the middle parts of the first positioning ring 41 and the second positioning ring 42. The positioning toothed plate 43 is used to penetrate and insert into the two positioning tooth cavities 39 when the first positioning ring 41 and the second positioning ring 42 rotate relative to each other until the two positioning tooth cavities 39 coincide. Therefore, during use, after adjusting the relative positions of the first positioning ring 41 and the second positioning ring 42 according to the shape of the building electrical and mechanical equipment, the positioning toothed plate 43 can be inserted to lock the relative positions of the first positioning ring 41 and the second positioning ring 42. In this solution, the module of the positioning tooth cavity 39 and the positioning toothed plate 43 can be set as needed according to the adjustment precision requirements.

[0030] As shown in the attached Figure 8As shown, in a further embodiment based on the above, a through hole is provided in the middle of the positioning tooth plate 43, a vertical and hollow limiting shaft is provided in the middle of the limiting seat 4, and a vertical limiting slide groove 451 is provided on the side wall of the limiting shaft. The positioning tooth plate 43 can be movably mounted on the outside of the limiting shaft through the through hole in the middle, and a limiting slide rod 45 slidably connected to the limiting slide groove 451 is provided on the inner side of the positioning tooth plate 43. A rotating block 44 is rotatably installed in the middle of the limiting shaft. The rotating block 44 is located inside the limiting shaft and a threaded curved groove 452 is provided on the side wall corresponding to the limiting slide groove 451. The inner end of the limiting slide rod 45 extends and is slidably installed in the threaded curved groove 452. The rotating block 44 is used to rotate and drive the positioning tooth plate 43 to slide up and down along the limiting slide groove 451.

[0031] In this way, when in use, the rotating block 44 can be rotated as needed. Due to the connection between the threaded curved groove 452 on the rotating block 44 and the limiting slide bar 45, the limiting slide bar 45 can drive the positioning tooth plate 43 to move upward along the limiting slide groove 451 to disengage from the positioning tooth cavity 39, thereby releasing the restriction effect on the first positioning ring 41 and the second positioning ring 42, facilitating the rotation of the first positioning ring 41 and the second positioning ring 42, so that the ratio of the distance between adjacent first clamping plates 2 is equal to the length-to-width ratio of the building's mechanical and electrical periphery; then, the rotating block 44 is rotated in the opposite direction until the positioning tooth plate 43 moves downward along the limiting slide groove 451 to be reinserted into the positioning tooth cavity 39, thereby achieving the positioning effect of the relative positions of the first positioning ring 41 and the second positioning ring 42.

[0032] The upper end of the rotating block 44 extends out of the upper end of the limit shaft and is provided with a circular driving knob. In this way, the rotating block 44 can be driven easily. When the above scheme is used, electromechanical equipment of different sizes can be pre-demonstrated as needed, and corresponding positioning marks can be made on the bevel gear ring 34 according to the demonstration results, so as to facilitate quick adjustment for motor equipment of different sizes.

[0033] As attached Figure 9 As shown, in another specific embodiment based on the above, the lower end of the limit seat 4 is inserted into the upper end of the support plate 11 through two vertical insertion rods so as to be movable up and down. In this way, the movement of the limit seat 4 can be restricted to prevent the movement of the limit seat 4 from affecting the adjustment accuracy of the first positioning ring 41 and the second positioning ring 42.

[0034] A threaded hole 46 is provided in the middle of the upper end of the support plate 11, and a second threaded rod 47 for threaded connection with the threaded hole 46 is rotatably installed in the middle of the limit seat 4, and the upper end of the second threaded rod 47 extends out of the limit seat 4. In this way, the limit seat 4 can be easily disassembled and fixed through the second threaded rod 47.

[0035] In this solution, the second threaded rod 47 can be rotatably arranged in the middle of the above-mentioned rotating block 44 and is rotationally limited inside the limit seat 4. In this way, the second threaded rod 47 can be rotated. According to the plug-in connection between the support plate 11 and the limit seat 4, under the limitation of the movement direction of the limit seat 4, the rotating second threaded rod 47 can drive the limit seat 4 to move upward through its threaded connection with the threaded hole 46, and make the bevel gear 32 and the bevel gear ring 34 separate from each other. After that, rotate the rotating block 44 to adjust the rotation of the first positioning ring 41 and the second positioning ring 42. Thus, when rotating the limit slide rail 37, it is possible to avoid the meshing connection between the bevel gear 32 of the first threaded rod 31 and the bevel gear ring 34, resulting in the rotation of the first threaded rod 31, and avoid the offset of the first clamping plate 2, increasing the adjustment accuracy.

[0036] In another specific embodiment based on the above, the scissor lift 1 is provided with movable or lockable universal wheels in an array. In this way, it is convenient to move the scissor lift 1 and adjust the angle of the whole device.

[0037] It should be noted that the terms such as "up", "down", "left", "right", "front", "back" cited in the invention are only for the convenience of description and are not used to limit the scope of implementation of the invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the invention.

[0038] The above is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, refinements and variations can be made to these embodiments without departing from the principle and spirit of the present invention, which should be regarded as the protection scope of the present invention.
