Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of installation frame, in particular to a prefabricated installation frame for building mechanical and electrical equipment. BACKGROUND

[0002] Building mechanical and electrical equipment is a general term for equipment in buildings that provides power, lighting, air conditioning, communication, fire protection, security and other facilities. These devices usually include electrical systems, lighting systems, air conditioning systems, communication systems, fire protection systems, security systems, etc. The normal operation of building mechanical and electrical equipment is crucial to ensure the normal use and safety of buildings. The main goal of the installation frame is to ensure that these mechanical and electrical equipment can operate safely, efficiently and stably, and provide a comfortable environment for users inside the building.

[0003] After searching, the authorized announcement No. CN222316590U Chinese patent document discloses a prefabricated installation frame for building mechanical and electrical equipment, which comprises a support rod and two fixed plates. The support rod top is provided with a socket on both sides. The support rod top is provided with a limiting mechanism near the socket on both sides. The limiting mechanism comprises a vertical plate fixedly connected with a vertical plate. Two limiting rods are slidably penetrated through the vertical plate. Two circular holes are formed in the vertical plate and are matched with the limiting rods. A second inclined tooth plate is fixedly connected to one side of the two limiting rods near the socket. This patent provides greater flexibility for the installation of building mechanical and electrical equipment. It can be adjusted according to actual needs to meet the requirements of different equipment and space, maximize the use of space inside the building, improve space utilization, and make the installation process of building mechanical and electrical equipment more efficient, shorten the construction period, and reduce the engineering cost.

[0004] Based on the search and prior art, it is found that after the height adjustment of the frame is completed, when the self-weight of the carried mechanical and electrical equipment is large, in order to offset the overturning moment caused by the weight of the equipment, improve the overall lateral displacement resistance and anti-instability ability of the structure, a diagonal bracing rod (such as a diagonal bracing rod) is needed to strengthen the stability of the structure. However, the above device has the function of height adjustment, but does not set such a diagonal bracing rod. It should be noted that when the height parameters of the frame are different, the installation position of the diagonal bracing rod is significantly related, that is, even if the diagonal bracing angle is maintained unchanged, the connection node position of the diagonal bracing rod with the frame body also needs to be adaptively changed with the height adjustment to ensure that the diagonal bracing rod is always in the optimal stress state and effectively plays a stabilizing role. SUMMARY

[0005] The purpose of the present application is to provide a prefabricated installation frame for building mechanical and electrical equipment to solve the problems raised in the background art.

[0006] The technical scheme of the present application is: a prefabricated mounting frame of building electromechanical equipment, comprising two square cylinders and two support rods corresponding to the two square cylinders, the cross section of the two support rods is square, the square cylinder is slidably sleeved on the corresponding support rod, the four sides of the square cylinder are provided with inclined openings connected in the cylinder, the inside of the inclined opening is slidably inserted with an inclined support rod, the four sides of the support rod are provided with a plurality of inclined grooves linearly distributed along the vertical direction and at equal distances, the surface of the inclined support rod is fixed with a plurality of inclined blocks linearly distributed along the inclined direction and at equal distances, and the inclined support rod is connected with the inclined grooves on the corresponding side of the support rod through the inclined blocks.

[0007] Preferably, the bottom of the support rod is fixed with a mounting plate, and the mounting plate is provided with positioning holes at the four corners.

[0008] Preferably, the top ends of the two square cylinders are fixed with a horizontal cylinder, and the inside of the horizontal cylinder is provided with a driving assembly for synchronously moving the two support rods in the same direction.

[0009] Preferably, the driving assembly comprises two bearing seats and two threaded rods, the two bearing seats are fixed with the two square cylinders respectively, one end of the two threaded rods is rotatably installed in the bearing seat respectively, the top end of the two support rods is provided with an internal thread hole, and the rod body of the two threaded rods is installed in the two internal thread holes through threads respectively.

[0010] Preferably, the driving assembly further comprises a synchronous rod, both ends of the horizontal cylinder are provided with rotating holes, both ends of the synchronous rod are rotatably installed in the two rotating holes respectively, both ends of the synchronous rod are fixed with first bevel gears coaxially arranged, the top end of the two threaded rods is fixed with second bevel gears coaxially arranged, the bevel tips of the two first bevel gears are consistent and meshed with the two second bevel gears respectively.

[0011] Preferably, one end of the horizontal cylinder is fixed with a bracket on the outside, both sides of the bracket are provided with circular holes, one worm is rotatably installed in the holes of the two circular holes, one end of the synchronous rod is fixed with a worm wheel coaxially arranged, and the worm is meshed with the worm wheel.

[0016] The application provides the assembly type mounting frame of the building electromechanical equipment, and has the following improvements and advantages compared with the prior art.

[0017] Firstly, the self-adaptive diagonal bracing adjustment is realized based on the diagonal top driving principle, and the inclination angle of the diagonal bracing rod is kept constant in the whole adjustment process; when the support rod bearing the electromechanical equipment is adjusted in height, the combined length of the support rod and the square cylinder changes synchronously with the height parameter, and the diagonal bracing rod is driven to displace radially outward; in this process, the relative distance between the support rod and the top of the diagonal bracing rod increases with the increase of the combined length, and the top end of the diagonal bracing rod and the top end of the support rod are kept flush, so that the force transmission path is stable; therefore, in the dynamic process of the overall height adjustment of the rack, the diagonal bracing force provided by the diagonal bracing rod is dynamically adjusted in correlation with the change of the combined length of the support rod and the square cylinder, and is always adapted to the structural stress requirement at the current height.

[0018] Secondly, after the height adjustment of the traditional diagonal bracing structure, manual disassembly, re-punching positioning and installation of the diagonal bracing (such as adjusting the connection node of the diagonal bracing rod and the frame and replacing the diagonal bracing rod with different lengths) are needed, and the operation process is complicated and depends on professional personnel; the self-adaptive structure has the characteristic that the height adjustment and the adaptation of the diagonal bracing are completed synchronously, and manual intervention in the installation position or length of the diagonal bracing is not needed, and only through the height adjustment action of the support rod, the radial displacement and force adaptation of the diagonal bracing rod can be automatically completed, so that the total time consumption of the height adjustment is greatly shortened (especially suitable for scenarios that need to frequently adjust the height, such as production line equipment model change and workshop layout optimization); the structural hidden danger caused by installation error (such as node loosening and angle deviation) is avoided, the dependence on the professional skills of the operator is reduced, and the safety and convenience of the on-site operation are improved.

[0031] The present application will be described in detail below, and the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] The present application provides an assembled mounting frame for building electromechanical equipment by improvement. The technical solutions of the present application are as follows:

[0033] As Figures 1 to 9As shown, the embodiment of the present application provides a prefabricated installation frame of building electromechanical equipment, which comprises two square cylinders 1 and two support rods 2 corresponding to the two square cylinders 1 respectively, the cross section of the two support rods 2 is square, the square cylinder 1 is slidably sleeved on the corresponding support rod 2, the four sides of the square cylinder 1 are provided with inclined openings connected in the cylinder, the inside of the inclined opening is slidably inserted with an inclined strut 3, the four sides of the support rod 2 are provided with a plurality of inclined grooves 4 which are linearly distributed at equal distances in the vertical direction, the surface of the inclined strut 3 is fixed with a plurality of inclined blocks 5 which are linearly distributed at equal distances in the inclined direction, the inclined strut 3 is engaged and connected with the inclined groove 4 of the corresponding side of the support rod 2 through the inclined block 5.

[0034] Through the above connection relationship, it can be known that the inclined strut 3 is engaged and connected with the support rod 2 through the inclined block 5 and the inclined groove 4 of the corresponding side of the support rod 2, so it can be known that the inclined strut 3 and the support rod 2 form an inclined jacking structure, when the support rod 2 moves downward relative to the square cylinder 1, the support rod 2 pushes the corresponding inclined block 5 through the inclined groove 4, so that the inclined strut 3 is subsequently moved out obliquely downward, the inclined strut 3 is displaced outward in the radial direction, the inclination angle of the inclined strut 3 is always kept constant in the whole adjusting process, the top end of the inclined strut 3 and the top end of the support rod 2 are always kept flush, so as to ensure the stability of the force transmission path, it can be known from the above that the self-adaptive inclined strut adjustment is realized based on the inclined jacking transmission principle, the inclination angle of the inclined strut 3 is always kept constant in the whole adjusting process; when the support rod 2 carrying the electromechanical equipment is adjusted in height, the combined length of the support rod 2 and the square cylinder 1 changes synchronously with the height parameter, which drives the inclined strut 3 to displace outward in the radial direction; in this process, the relative distance between the support rod 2 and the top of the inclined strut 3 increases with the increase of the combined length, and the top end of the inclined strut 3 and the top end of the support rod 2 are always kept flush, so as to ensure the stability of the force transmission path; it can be seen that in the dynamic process of the overall height adjustment of the rack, the inclined strut force provided by the inclined strut 3 is dynamically adjusted in correlation with the change of the combined length of the support rod 2 and the square cylinder 1, which always adapts to the structural stress demand under the current height.

[0035] Specifically, combined with the accompanying drawings, Figure 7 As shown, the bottom of the support rod 2 is fixed with a mounting plate 6, and the four corners of the mounting plate 6 are provided with positioning holes 7.

[0036] Through the above connection relationship, the mounting plate 6 is placed on the ground, and then the fixing bolts are passed through the positioning holes 7 and fixed on the ground, so that the mounting plate 6 is fixed on the ground.

[0037] Specifically, combined with the accompanying drawings, Figure 2 and the accompanying drawings, Figure 3As shown, the top ends of the two square cylinders 1 are fixed with a horizontal cylinder 8, the inside of the horizontal cylinder 8 is provided with a driving assembly for synchronously moving the two support rods 2 in the same direction, the driving assembly comprises two bearing seats 9 and two threaded rods 10, the two bearing seats 9 are respectively fixed with the two square cylinders 1, one end of the two threaded rods 10 is respectively rotatably installed in the bearing seat 9, the top end of the two support rods 2 is provided with an internal threaded hole, the rod body of the two threaded rods 10 is respectively installed in the two internal threaded holes through threads;

[0038] It should be noted that the inner wall shape of the square cylinder 1 is matched with the outer wall shape of the support rod 2 (both are square structures), and the inner wall size of the square cylinder 1 is slightly larger than the outer wall size of the support rod 2. The gap design not only ensures that the support rod 2 can be smoothly inserted into the inside of the square cylinder 1, but also can limit the movement track of the support rod 2 in the square cylinder 1 through the "anti-rotation" feature of the square structure, that is, only allows the support rod 2 to move linearly along the axis direction of the square cylinder 1, completely avoids the support rod 2 from rotating circumferentially during the movement, and provides a stable movement constraint basis for the subsequent threaded rod 10 to drive the support rod 2 to slide linearly through thread transmission.

[0039] Secondly, in the specific action process of thread transmission, one end of the support rod 2 is usually provided with an internal threaded hole matched with the external thread of the threaded rod 10 (or fixed with a connecting seat with an internal thread), when the threaded rod 10 rotates under the driving of the power, the external thread of the threaded rod 10 will form meshing transmission with the internal thread on the support rod 2; since the square cylinder 1 has limited the rotation of the support rod 2 through the square fitting, the support rod 2 cannot rotate synchronously with the rotation of the threaded rod 10, at this time the meshing force between the threads will convert the rotary motion of the threaded rod 10 into the linear motion of the support rod 2 along the axis direction of the square cylinder 1, if the threaded rod 10 rotates clockwise, the support rod 2 will stretch out along the square cylinder 1; if the threaded rod 10 rotates counterclockwise, the support rod 2 will contract inward along the square cylinder 1, realizing the precise adjustment of the extension length of the support rod 2.

[0040] Specifically, combined with the accompanying drawings Figure 2 and the accompanying drawings Figure 3 As shown, the driving assembly further comprises a synchronous rod 11, both ends of the horizontal cylinder 8 are provided with rotating holes, both ends of the synchronous rod 11 are rotatably installed in the two rotating holes, both ends of the synchronous rod 11 are fixed with first bevel gears 12 coaxially arranged therewith, the top end of the two threaded rods 10 is fixed with second bevel gears 13 coaxially arranged therewith, the taper tips of the two first bevel gears 12 are consistent and respectively mesh with the two second bevel gears 13;

[0041] It needs to be supplemented that the synchronous rod 11 as the core transmission component is coaxially fixedly connected (such as key connection or welding) at both ends with the first bevel gear 12, ensuring that the synchronous rod 11 can directly drive the first bevel gear 12 at both ends to rotate synchronously when rotating, without transmission gap, avoiding transmission delay or slipping due to loose connection. Each first bevel gear 12 is precisely meshed with the second bevel gear 13 at the corresponding position, and the tooth number ratio of the first bevel gear 12 and the second bevel gear 13 is optimized and designed, and the transmission ratio can be adjusted according to actual needs (for example, when the threaded rod 10 needs to rotate quickly, a small-tooth first bevel gear 12 can be designed to drive a large-tooth second bevel gear 13, or vice versa), meeting the adjustment efficiency demand in different scenes. The second bevel gear 13 is coaxially fixed with the threaded rod 10, and when the first bevel gear 12 rotates, it will drive the second bevel gear 13 to rotate through the meshing action between the teeth, and then drive the threaded rod 10 to rotate synchronously.

[0042] Especially crucially, the cone tips of the two first bevel gears 12 are kept consistent in direction (for example, both are directed towards the center direction of the synchronous rod 11), and this design makes the two first bevel gears 12 produce the same force direction on the second bevel gears 13 they mesh with when rotating with the synchronous rod 11, thereby ensuring that the rotation directions of the two second bevel gears 13 are completely consistent, and finally realizing the synchronous and same-direction rotation of the two threaded rods 10. This synchronous and same-direction rotation characteristic has important practical significance. If the threaded rod 10 is used to drive two execution components (such as two clamping arms of a clamping mechanism, two support screws of a lifting platform, etc.) of a device, synchronous and same-direction rotation can ensure that the movement speed and displacement of the two execution components are completely consistent, avoiding device jamming, tilting or damage due to asynchronous movement, and ensuring the stability and safety of device operation. At the same time, compared with separately driving two threaded rods 10, the synchronous transmission structure realized by the synchronous rod 11 and the bevel gear set is more concise, reducing the number of driving components and the device failure rate and maintenance cost.

[0043] In addition, to ensure the smoothness and durability of the bevel gear meshing transmission, the tooth surfaces of the first bevel gear 12 and the second bevel gear 13 are usually subjected to quenching treatment to improve hardness and wear resistance, and grease can be applied at the meshing position to reduce friction and wear between the teeth, prolong the service life of the components, and further ensure the long-term stability of the synchronous transmission effect.

[0044] Specifically, as shown in the accompanying drawings, Figure 3 One end of the horizontal cylinder 8 is fixed with a support 14 on the outside, and the support 14 is provided with a circular hole on both sides. A worm 15 is rotatably installed in the two holes. One end of the synchronous rod 11 is fixed with a worm gear 16 coaxially arranged with the synchronous rod 11. The worm 15 is meshed with the worm gear 16. One end of the worm 15 is fixed with a Z-shaped handle 17, and the outer side of the Z-shaped handle 17 is sleeved with a rubber sleeve.

[0045] From the above connection relationship, it can be seen that in the actual operation process, when the rotating state of the synchronous rod 11 needs to be adjusted, the worker only needs to hold the rubber sleeve part of the Z-shaped handle 17 with one hand, and rotate the Z-shaped handle 17 to the desired direction, which can drive the worm 15 to rotate around its own axis in the circular hole of the support 14. Since the worm 15 is engaged with the worm wheel 16, when the worm 15 rotates, it will drive the worm wheel 16 to rotate synchronously through the gear transmission. Because the worm wheel 16 is coaxially fixed with the synchronous rod 11, the worm wheel 16 will directly drive the synchronous rod 11 to rotate around its own axis at the same time, thereby realizing the subsequent linkage action of the synchronous rod 11 (such as driving the internal components of the horizontal cylinder 8 to adjust the position, etc.). What is particularly important is that the engagement structure of the worm 15 and the worm wheel 16 has good self-locking performance. This self-locking property is derived from the transmission characteristics of the two, that is, only when the worm 15 actively rotates can it drive the worm wheel 16 to rotate, and the worm wheel 16 cannot drive the worm 15 to rotate in the opposite direction. Therefore, when the worker stops rotating the Z-shaped handle 17 and there is no external force acting on the worm 15, the worm wheel 16 will remain in the current position, thereby preventing the synchronous rod 11 from rotating by itself. This effectively avoids accidental rotation of the synchronous rod 11 due to external vibration, load pressure and other factors, ensuring the stability and safety of the overall operation of the equipment, and is particularly suitable for working scenarios that require long-term fixation of the angle or position of the synchronous rod 11, such as mechanical processing positioning, equipment support adjustment, etc.

[0046] Specifically, combined with the accompanying drawings Figure 5 As shown, two groups of rollers 18 are rotatably installed on both sides of the beveled opening, and the rollers 18 are in contact with the diagonal struts 3 in the beveled opening.

[0047] From the above connection relationship, it can be seen that the rollers 18 are provided to reduce the friction between the diagonal struts 3 and the beveled opening.

[0048] Specifically, combined with the accompanying drawings Figure 6 - The Figure 9 As shown, the bottom end of the diagonal strut 3 is rotatably fixed with a rolling wheel 19.

[0049] From the above connection relationship, it can be seen that the rolling wheel 19 is provided to reduce the friction at the bottom end of the diagonal strut 3.

[0050] Specifically, combined with the accompanying drawings Figure 2 As shown, the outside of the horizontal cylinder 8 is fixed with an electromechanical fixed plate 20, and the plate surface of the electromechanical fixed plate 20 is provided with a plurality of mounting holes 21 and a plurality of straight slots 22.

[0051] From the above connection relationship, it can be seen that the mounting holes 21 and the straight slots 22 are provided to facilitate the installation of electromechanical equipment.

[0052] To supplement the above, according to the specifications of electromechanical equipment, a plurality of installation frames can be provided on the ground to facilitate the installation of electromechanical equipment.

[0053] Working principle: the worker makes the worm 15 rotate through the Z-shaped handle 17, the worm 15 drives the worm wheel 16 to rotate, because the worm wheel 16 rotates with the synchronous rod 11, the worm wheel 16 drives the synchronous rod 11 to rotate, and the worm 15 and the worm wheel 16 are self-locking, so that the synchronous rod 11 cannot rotate by itself under the action of external force;

[0054] When the synchronous rod 11 rotates, the first bevel gears 12 at both ends of the synchronous rod 11 rotate with the synchronous rod 11, and the first bevel gears 12 drive the threaded rods 10 through the second bevel gears 13 engaged therewith, because the two first bevel gears 12 have consistent tapered tips, so the two second bevel gears 13 rotate in the same direction, thereby the two threaded rods 10 rotate synchronously and in the same direction;

[0055] Because the square cylinder 1 is slidably sleeved on the corresponding support rod 2, the support rod 2 can only move linearly relative to the square cylinder 1, when the threaded rod 10 rotates, the threaded rod 10 drives the support rod 2 to slide linearly along the square cylinder 1 through the threaded transmission form;

[0056] When the support rod 2 moves downward relative to the square cylinder 1, the support rod 2 pushes the corresponding inclined block 5 through the inclined chute 4, so that the inclined support rod 3 is subsequently moved obliquely downward, and the inclined support rod 3 is displaced radially outward, and the inclination angle of the inclined support rod 3 is kept constant during the entire adjustment process, and the top end of the inclined support rod 3 and the top end of the support rod 2 are always flush, so as to ensure the stability of the force transmission path, and it can be seen that the self-adaptive inclined support adjustment is realized based on the inclined top transmission principle, and the inclination angle of the inclined support rod 3 is kept constant during the entire adjustment process; when the support rod 2 of the bearing machine electrical equipment is adjusted in height, the combined length of the support rod 2 and the square cylinder 1 changes synchronously with the height parameter, and the inclined support rod 3 is displaced radially outward; during this process, the relative distance between the support rod 2 and the top of the inclined support rod 3 increases with the increase of the combined length, and the top end of the inclined support rod 3 and the top end of the support rod 2 are always flush, so as to ensure the stability of the force transmission path; it can be seen that in the dynamic process of the overall height adjustment of the rack, the inclined support force provided by the inclined support rod 3 is dynamically adjusted in correlation with the change of the combined length of the support rod 2 and the square cylinder 1, and always adapts to the structural stress requirement under the current height;

[0057] In summary, the traditional inclined strut structure needs to be manually disassembled, re-punched and positioned, and installed with the inclined strut (such as adjusting the connection node of the inclined strut rod 3 and the frame, and replacing the inclined strut rod 3 of different lengths) after the height adjustment of the rack. The operation process is complicated and depends on professional personnel. The adaptive structure has the characteristic of "synchronous completion of height adjustment and inclined strut adaptation", does not need manual intervention of the installation position or length of the inclined strut, and only through the height adjustment action of the support rod 2, the radial displacement and force adaptation of the inclined strut rod 3 can be automatically completed, which greatly shortens the total time consumption of height adjustment (especially suitable for scenarios that need to frequently adjust the height, such as production line equipment model change and workshop layout optimization), avoids the "structural hidden danger caused by installation error" (such as node loosening and angle deviation) when manually adjusting the inclined strut, reduces the dependence on the professional skills of the operator, and improves the safety and convenience of on-site operation.

[0058] The above description enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
