Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical installation auxiliary tools, in particular to a transfer device for electromechanical equipment installation. Background Art

[0002] After the initial construction of a building is completed, the construction of the electromechanical project needs to be carried out. In the electromechanical installation project, the installation of equipment, electrical appliances, lines, and pipelines is restricted by height, equipment weight, and size. In order to complete the installation of some components, installation auxiliary devices are usually required. These auxiliary devices include lifting equipment, etc., which can effectively improve the installation efficiency and safety, ensure that the project proceeds according to the plan, and meet the design requirements.

[0003] The existing electromechanical installation auxiliary equipment is usually for lifting, and there are few devices that can expand left and right, and the width cannot be set differently according to different devices. In addition, for the directly purchased related equipment, the main structural parts are not of general type, and the manufacturing cost is too high. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a transfer device for electromechanical equipment installation to solve the technical problem that the existing one cannot adapt to the width of electromechanical equipment.

[0005] To achieve the above purpose, the utility model provides a transfer device for electromechanical equipment installation, which includes two side frames symmetrically arranged left and right. Casters are arranged at the bottom of the side frames to facilitate the free movement of the transfer device. The side frames are welded by square steel and steel plates. A horizontal extension mechanism for adjusting the distance between the side frames is arranged between the side frames. The side frames are connected upward through a lifting mechanism to a bracket for carrying electromechanical equipment; a first fork-shaped member is fixedly arranged in the middle of the bottom of the side frame, and a third fork-shaped member is fixedly arranged on the side frame. The horizontal extension mechanism includes two support rods vertically arranged front and back. A cross bar is fixedly connected between the support rods, and a hinge piece is fixedly arranged on the cross bar. An electric push rod is hinged between the first fork-shaped member and the hinge piece. Second fork-shaped members are fixedly connected to both ends of the support rod, and a connecting rod is hinged between the second fork-shaped member and the third fork-shaped member.

[0006] The casters arranged at the bottom of the side frames enable the transfer device to move conveniently in the building, improving the construction efficiency and flexibility.

[0007] The side frames are welded by square steel and steel plates, ensuring the stability and durability of the device and enabling it to carry heavier electromechanical equipment. Square steel is a commonly used material in construction sites, facilitating local material collection and reducing the production cost.

[0008] The horizontal extension mechanism can adjust the distance between the side frames, adapt to electromechanical equipment of different widths, and improve the applicable range of the device. The bracket connected by the lifting mechanism can carry various electromechanical equipment and can adjust the height according to needs, facilitating installation and maintenance.

[0009] Through the reasonable arrangement of the first fork-shaped part, the second fork-shaped part, the third fork-shaped part, the connecting rod and the electric push rod, the horizontal extension mechanism can achieve smooth extension and contraction, with simple and flexible operation, convenient to use, and can significantly improve the installation and maintenance efficiency of electromechanical equipment.

[0010] Furthermore, the side frame includes a pair of symmetrically arranged columns. At the bottom of the columns, there is a bottom beam fixedly connected to the bottom ends of the columns. At the top of the columns, there is a top plate fixedly connected to the top ends of the columns. At least two cross beams are arranged in the middle part of the columns. The columns, the bottom beam and the cross beams are square steel, and the top plate is a steel plate. The side frame includes a pair of symmetrically arranged columns and is connected by the bottom beam and the cross beams to form a stable frame structure, enhancing the stability of the device. The columns, the bottom beam and the cross beams are all made of square steel, increasing the strength and durability of the side frame and enabling it to bear a large load.

[0011] Furthermore, the first fork-shaped parts are distributed on the bottom beam, and the third fork-shaped parts are distributed on the bottom beam and the columns.

[0012] Furthermore, a middle mounting position is arranged in the middle of the top plate, and side mounting positions are respectively arranged on both sides of the top plate. The lifting mechanism includes a stepper motor mounted on the middle mounting position and a commutator mounted on the side mounting positions. A first bevel gear is mounted on the rotating shaft of the stepper motor. The first bevel gear is meshed and connected with a second bevel gear. The second bevel gear is connected to the commutator through a coupling. A lead screw is arranged at the center of the commutator. The top of the lead screw is fixedly connected with a fixing plate. The fixing plate is fixedly connected with the bracket through fixing screws.

[0013] The stepper motor is mounted in the middle of the top plate. Power is transmitted to the commutator through the first bevel gear and the second bevel gear. The lead screw at the center of the commutator converts the rotational motion into a linear motion, achieving efficient power transmission.

[0014] The stepper motor has good speed and position control capabilities, can achieve precise adjustment of the height of the bracket, meet the installation requirements of different height needs, and improve the working precision and efficiency.

[0015] Through the bevel gear transmission system and the lead screw mechanism of the commutator, the entire lifting process is stable and reliable, reducing jitter and noise, and improving the stability and operation comfort of the equipment.

[0016] The lead screw and the fixing plate are connected to form a strong load-bearing structure, which can bear a large load and is suitable for the installation and transfer of electromechanical equipment of different weights.

[0017] Furthermore, the lifting mechanism includes a fourth fork-shaped member disposed at the bottom of the bracket and a fifth fork-shaped member disposed at both ends of the top plate. A first bearing and a second bearing are sequentially arranged in the direction from the fifth fork-shaped member towards the middle of the top plate. A lead screw is installed between the first bearing and the second bearing. A stepper motor for driving the lead screw is installed at one end of the second bearing. A ball nut is installed on the lead screw. A first hinge rod is installed between the ball nut and the fourth fork-shaped member. A second hinge rod is hinged between the middle of the first hinge rod and the fifth fork-shaped member.

[0018] The stepper motor can provide precise speed and position control, enabling the lifting height of the bracket to be accurately adjusted to meet the requirements of different installation heights. Through the support and transmission of the bearings and hinge rods, the bracket remains stable and balanced during the lifting process, avoiding tilting or instability caused by single-point stress. The combined drive of the ball nut and the lead screw has high transmission efficiency and low friction, ensuring a smooth and stable lifting process and improving work efficiency.

[0019] Furthermore, the lifting mechanism includes an upper trough body and a lower trough body. The upper trough body is fixedly connected to the bracket, and the lower trough body is fixedly connected to the top plate. Fixed hinge positions and movable hinge positions are respectively arranged on the side walls of the upper trough body and the lower trough body. The movable hinge position includes a strip-shaped groove arranged on the side wall. Symmetrically left and right hinge frames are hinged between the upper trough body and the lower trough body. A screw rod assembly for adjusting the height of the hinge frames is arranged between the hinge frames. The screw rod assembly includes two ball nuts arranged front and back. The ball nuts are connected by a lead screw. Both ends of the ball nuts are respectively connected to the hinge frames on both sides. A wheel disc is installed at one end of the lead screw.

[0020] The design of the hinge frames and the strip-shaped grooves allows the bracket to be adjusted in height within a large range, adapting to the installation requirements of electromechanical equipment at different heights and improving the applicability of the device.

[0021] The upper trough body and the lower trough body are connected by symmetrically left and right hinge frames, ensuring the balance and stability of the bracket during the lifting process, preventing tilting or shaking, and guaranteeing safety.

[0022] By rotating the wheel disc at the end of the lead screw, the height adjustment of the bracket can be achieved. The operation is simple and labor-saving, without complex operation steps, reducing the use difficulty and labor intensity.

[0023] Furthermore, the hinge frame is formed by connecting two X-shaped hinge components end to end.

[0024] The X-shaped hinge assembly design allows for a large range of motion, adapts to the adjustment requirements of the bracket at different heights, and enhances the applicability and flexibility of the equipment. The X-shaped structure of the hinge frame has good vibration resistance and can effectively absorb and relieve external vibrations during the lifting process, improving the stability and service life of the overall device. The hinge frame formed by connecting two X-shaped hinge assemblies end to end not only improves stability, load-bearing capacity, and smoothness but also increases the structural compactness and motion flexibility, significantly enhancing the overall performance and usage effect of the transfer device.

[0025] The transfer device for electromechanical equipment installation provided by the present utility model has the following advantages:

[0026] The side frame is welded with square steel and steel plates, ensuring its stability and durability, and can reliably carry heavy electromechanical equipment. Casters are installed at the bottom, enabling the transfer device to move easily within the building, significantly improving the construction efficiency and flexibility. Square steel, as a common construction material on the construction site, is convenient for obtaining materials locally and reduces the manufacturing cost at the same time.

[0027] The horizontal extension mechanism is designed flexibly and can adjust the distance between the side frames to adapt to electromechanical equipment of different widths, expanding the applicable range of the device. The bracket connecting the lifting mechanism can be adjusted in height as needed, facilitating the installation and maintenance operations of the equipment.

[0028] By the reasonable arrangement of the first fork-shaped part, the second fork-shaped part, the third fork-shaped part, the connecting rod, and the electric push rod, the horizontal extension mechanism realizes smooth extension and contraction, with simple and flexible operation, significantly improving the installation and maintenance efficiency of electromechanical equipment.

[0043] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0044] Refer to Figure 1 , the present utility model provides a transfer device for the installation of electromechanical equipment, including two side frames 30 symmetrically arranged left and right. A horizontal extension mechanism 40 for adjusting the distance between the side frames 30 is arranged between the side frames 30. Caster wheels 50 for facilitating the free movement of the transfer device are arranged at the bottom of the side frames 30. The side frames 30 are connected upward to a bracket 10 through a lifting mechanism 20, and the bracket 10 is used to carry electromechanical equipment.

[0045] Refer to Figure 2 and Figure 4, the side frame 30 includes a pair of symmetrically arranged columns 31. A bottom beam 32 fixedly connected to the bottom end of the column 31 is provided at the bottom of the column 31, and a top plate 34 fixedly connected to the top end of the column 31 is provided at the top of the column 31. At least two cross beams 33 are provided in the middle part of the column 31.

[0046] A first fork-shaped member 35 is fixedly provided on the bottom beam 32, and an electric push rod 41 is hinged to the first fork-shaped member 35.

[0047] Refer to Figure 3 and Figure 4 , the horizontal extension mechanism 40 includes two support rods 43 arranged vertically front and back. A cross bar 44 is fixedly connected between the support rods 43. A hinge piece 44 is fixedly provided on the cross bar 44, and the movable end of the electric push rod 41 is hinged to the hinge piece 44. Second fork-shaped members 45 are respectively fixedly connected to both ends of the support rod 43. A third fork-shaped member 47 fixedly connected to the bottom beam 32 and the column 31 of the side frame 30 is also included, and a connecting rod 46 is hinged between the second fork-shaped member 45 and the third fork-shaped member 47.

[0048] Working principle

[0049] In the initial state, the electric push rod 41 is in the maximum extended state, and the two side frames 30 are located relatively close to each other.

[0050] When the electric push rod is started and the horizontal extension mechanism needs to be deployed, the electric push rod 41 starts to contract. The movable end of the electric push rod 41 is hinged to the cross bar 44 through the hinge piece 44. As the electric push rod 41 contracts, it drives the cross bar 44 to move downward.

[0051] Movement of the support rod: Since the cross bar 44 is fixedly connected between the two support rods 43, the movement of the cross bar 44 will directly drive the support rod 43 to move downward.

[0052] Function of the hinged connecting rod: Second fork-shaped members 45 are respectively fixedly connected to both ends of the support rod 43. The second fork-shaped member 45 is hinged to the third fork-shaped member 47 through the connecting rod 46, and the third fork-shaped member 47 is respectively fixed on the bottom beam 32 and the column 31 of the side frame 30.

[0053] Movement of the connecting rod: As the support rod 43 moves downward, the second fork-shaped member 45 drives the connecting rod 46 to push outwards, pushing the side frames apart.

[0054] Completion of extension: The electric push rod 41 continues to contract, and the support rod 43 continues to move until the predetermined extension position is reached. At this time, the horizontal extension mechanism is deployed to form a stable support structure.

[0055] Retraction process: When the horizontal extension mechanism needs to be retracted, the electric push rod 41 starts to extend, pulls the hinge piece 44 and the cross bar 44 through the reverse acting force, and makes the support rod 43 move upward. The connecting rod 46 moves inward under the action of the hinge mechanism, pulls the support rod 43 back to the initial position, and completes the retraction process.

[0056] Through the above steps, the horizontal extension mechanism 40 utilizes the telescopic movement of the electric push rod 41 to achieve the synchronous movement of the support rod and the connecting rod system, thereby realizing the horizontal extension and retraction of the horizontal extension mechanism 40.

[0057] First embodiment of the lifting mechanism

[0058] Refer to Figure 5 , to adapt to the installation of the lifting mechanism 20, a middle mounting position 341 is provided in the middle of the top plate 34, and side mounting positions 342 are respectively provided on both sides of the top plate 34. The basic structures of the middle mounting position 341 and the side mounting positions 342 include a round hole for avoiding the shaft part of the mounting part and a fixing hole 343 for fixing the mounting part.

[0059] Refer to Figure 6 , the lifting mechanism 20 includes a stepping motor 21 and a commutator 25 mounted on the top plate 34. The stepping motor 21 is fixed to the middle mounting position 341 through a fastener, and the commutator 25 is fixed to the side mounting position 342 through a fastener. A first bevel gear 22 is mounted on the rotating shaft of the stepping motor 21. The first bevel gear 22 is meshed and connected with a second bevel gear 23. The second bevel gear 23 is connected to the commutator 25 through a coupling shaft 24. A lead screw 26 is provided at the center of the commutator 25. The top of the lead screw 26 is fixedly connected with a fixing plate 27. The fixing plate 27 is fixedly connected with the bracket 10 through fixing screws 28.

[0060] Second embodiment of the lifting mechanism

[0061] Refer to Figure 7 , the lifting mechanism 20 includes a fourth fork-shaped member 11 provided at the bottom of the bracket 10 and a fifth fork-shaped member 344 provided at both ends of the top plate 34. A first bearing 345 and a second bearing 346 are sequentially arranged from the fifth fork-shaped member 344 towards the middle of the top plate 34. A lead screw 26 is installed between the first bearing 345 and the second bearing 346. A stepping motor 21 for driving the lead screw 26 is installed at one end of the second bearing 346. A ball nut 203 is installed on the lead screw 26. A first articulated rod 201 is installed between the ball nut 203 and the fourth fork-shaped member 11. A second articulated rod 202 is articulated between the middle of the first articulated rod 201 and the fifth fork-shaped member 344.

[0062] The stepping motor 21 is installed in the middle of the top plate 34 and drives the lead screw 26 to rotate through a rotating shaft. One end of the lead screw 26 is provided with a ball nut 203, and the ball nut 203 moves axially along the lead screw 26 when the lead screw 26 rotates.

[0063] The first bearing 345 and the second bearing 346 are respectively arranged on the top plate 34 to support the rotation of the lead screw 26. The arrangement of the bearings ensures that the lead screw 26 maintains stable and smooth movement during rotation.

[0064] The ball nut 203 is connected to the fourth fork-shaped member 11 through the first hinge rod 201. As the ball nut 203 moves along the lead screw 26, the first hinge rod 201 moves accordingly, driving the second hinge rod 202 to be hinged.

[0065] The fourth fork-shaped member 11 is fixed to the bottom of the bracket 10. As the lead screw 26 rotates and the ball nut 203 moves, the bracket 10 realizes a lifting motion under the transmission of the hinge rods.

[0066] Embodiment III of the lifting mechanism

[0067] Refer to Figure 8 and Figure 9 As shown in, the lifting mechanism 20 includes an upper trough 205 and a lower trough 204. The upper trough 205 is fixedly connected to the bracket 10, and the lower trough 204 is fixedly connected to the top plate 34. Fixed hinge positions 209 and movable hinge positions 206 are respectively arranged on the side walls of the upper trough 205 and the lower trough 204. The movable hinge position 206 includes a strip-shaped groove 206 arranged on the side wall. A symmetrically arranged hinge frame 207 is hinged between the upper trough 205 and the lower trough 204. A screw rod assembly for adjusting the height of the hinge frame 207 is arranged between the hinge frames 207. The screw rod assembly includes two ball nuts 203 arranged front and back. The ball nuts 203 are connected by a lead screw 26. Both ends of the ball nuts 203 are connected to the hinge frames 207 on both sides. A disc 208 is installed at one end of the lead screw 26. The hinge frame 207 is formed by connecting two X-shaped hinge components end to end.

[0068] When the disc 208 is manually rotated, the lead screw 26 can change the distance between the two ball nuts 203, causing the height of the hinge frame 207 to change. Taking the bottom as an example, since one foot position of the hinge frame 207 is fixedly hinged to the lower trough 204, and the other foot position slides inside through the strip-shaped groove 206, the height between the upper trough 205 and the lower trough 204 changes accordingly, and then the height of the bracket 10 changes, realizing lifting adjustment.

[0069] A transfer device for electromechanical equipment installation provided by the present utility model has the following advantages:

[0070] The side frame is welded by square steel and steel plates, ensuring its stability and durability, and can reliably carry heavy electro-mechanical equipment. Casters are installed at the bottom, enabling the transfer device to move easily within the building, significantly improving the construction efficiency and flexibility. Square steel, as a common construction site material, is convenient for local material sourcing and reduces the manufacturing cost at the same time.

[0071] The horizontal extension mechanism is designed flexibly and can adjust the distance between the side frames to adapt to electro-mechanical equipment of different widths, expanding the applicable range of the device. The bracket connecting the lifting mechanism can adjust the height according to needs, facilitating the installation and maintenance operations of the equipment.

[0072] With the reasonable arrangement of the first fork-shaped part, the second fork-shaped part, the third fork-shaped part, the connecting rod and the electric push rod, the horizontal extension mechanism realizes smooth extension and contraction, is simple and flexible to operate, and significantly improves the installation and maintenance efficiency of electro-mechanical equipment.

[0073] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
