Description

Technical Field

[0001] The present application relates to the technical field of electromechanical installation auxiliary equipment, and in particular to a lifting device for electromechanical installation. Background Art

[0002] In some industrial projects, the installation of electromechanical equipment is usually involved. For electromechanical equipment installed at a higher position, it is necessary to use lifting equipment to install the electromechanical equipment.

[0003] Traditional electromechanical installation equipment mainly includes a base, a telescopic frame and a working platform. The two ends of the telescopic frame are connected to the base and the working platform respectively. When the lifting platform is in use, the base sits on the ground, and the telescopic frame drives the working platform to rise and fall. For example, a lifting device for electromechanical installation disclosed in the patent document with publication number CN118894480A uses a scissor-type telescopic frame to drive the working platform to rise and fall, so as to assist the installation of electromechanical equipment.

[0004] When the lifting device is in use, the working platform carries heavy objects (electromechanical equipment) and active loads (workers, whose positions on the working platform are not fixed). Due to the structural characteristics of the electromechanical equipment and the space limitations of the working platform, the loads at different positions on the working platform are not balanced, and there are certain safety hazards when the working platform is raised (for example, the lifting device may tip over, etc.). Summary of the invention

[0005] In order to reduce potential safety hazards of a lifting platform during use, the present application provides a lifting device for electromechanical installation.

[0006] The present application provides a lifting device for electromechanical installation using the following technical solution: A lifting device for electromechanical installation includes a base, a scissor-type telescopic frame installed on the base, and a working platform installed on the scissor-type telescopic frame. A counterweight block is arranged on the working platform, an adjustment component is arranged between the counterweight block and the working platform, the counterweight block is installed in the adjustment component, and the adjustment component can drive the counterweight block to move arbitrarily on the horizontal plane.

[0007] By adopting the above technical solution, during the operation of the lifting device, the base sits on the ground to support the scissor-type telescopic frame and the working platform, and the scissor-type telescopic frame drives the working platform to rise and fall. When the electromechanical equipment on the working platform is biased to one side of the working platform, the counterweight block can be driven to move to the opposite side of the electromechanical equipment through the adjustment component, thereby balancing the force on the working platform, reducing the force on one side of the lifting device, and reducing the risk of the lifting device tipping over.

[0008] Optionally, the adjustment assembly includes an adjustment rod, which is horizontally arranged and has one end rotatably connected to the working platform. The axis of the adjustment rod coincides with the center of the working platform on the horizontal plane, and the counterweight block is slidably fitted on the adjustment rod along the length direction of the adjustment rod.

[0009] By adopting the above technical solution, the end of the adjustment rod is rotatably connected to the center of the working platform. When the counterweight block slides to a position close to the rotation axis of the adjustment rod, the counterweight block is at the center of the working platform. In this state, the working platform is balanced in force. When the equipment is placed on the working platform, the counterweight block can be driven to move to any position within the plane by rotating the adjustment rod and sliding the counterweight block, thereby accurately balancing the force on the working platform.

[0010] Optionally, a driving rod is provided on the adjusting rod, and the driving rod is rotatably connected to the adjusting rod and is threadedly connected to the counterweight block.

[0011] By adopting the above technical solution, rotating the drive rod can drive the counterweight block to move, thereby adjusting the position of the counterweight block.

[0012] Optionally, a driving assembly is provided on the working platform, and the driving assembly includes a driving member and an abutment member. The abutment member is rotatably connected to the working platform and can slide. The driving member is used to drive the abutment member to rotate, and sliding the abutment member can connect the abutment member to the adjusting rod or the driving rod.

[0013] By adopting the above technical solution, the driving rod or the adjusting rod can be driven to move through the sliding abutment member, thereby simplifying the equipment structure and reducing the overall weight of the lifting equipment.

[0014] Optionally, the abutment member includes a friction disk and a rotating shaft, the rotating shaft is vertically arranged and rotatably connected to the working platform, the friction disk is connected to the end of the friction disk close to the ground, the driving rod is located below the friction disk, the rotating shaft can slide in a direction parallel to its own axis, the axis of the rotating shaft coincides with the rotating axis of the adjusting rod, sliding the rotating shaft upward can make the friction disk abut against the adjusting rod, and sliding the rotating shaft downward can connect the friction disk to the driving rod.

[0015] By adopting the above technical solution, when the rotating shaft moves in the axial direction, it can drive the friction disk to connect with the adjusting rod or the driving rod, thereby driving the adjusting rod or the driving rod.

[0016] Optionally, the end of the adjusting rod away from its own rotation axis is defined as the movable end, the end of the driving rod extends to the side of the adjusting rod rotation axis away from the movable end, the end of the driving rod is provided with a first bevel gear, a second bevel gear is provided under the friction plate, a transition piece is provided between the first bevel gear and the second bevel gear, and the transition piece is meshed with the first bevel gear and the second bevel gear at the same time.

[0017] By adopting the above technical solution, the end of the driving rod extends to the side of the adjusting rod rotation axis away from the movable end, so as to drive the counterweight to move to the center of the working platform. At the same time, the first bevel gear and the second bevel gear are linked by the transition piece, so that when the friction plate moves downward and abuts against the second bevel gear, it can drive the driving rod to rotate.

[0018] Optionally, a groove into which the friction disk can be embedded is provided on the adjusting rod and at a position on the second bevel gear corresponding to the friction disk.

[0019] By adopting the above technical solution, the friction disc is embedded in the embedded groove during the process of driving the second bevel gear or the adjusting rod to rotate, and the friction between the embedded groove and the friction disc is used to drive the second bevel gear or the adjusting rod to rotate. At the same time, the embedded groove can make the rotating shaft consistent with the axis of the second bevel gear, reducing the friction between the two in the horizontal direction, thereby increasing the service life of the friction disc.

[0020] Optionally, a mode conversion component is provided on the working platform, and the mode conversion component is used to drive the rotating shaft to slide. The mode conversion component includes an electromagnetic component and a permanent magnetic component. The permanent magnetic component is installed on the rotating shaft, and the electromagnetic component is installed on the working platform. The end of the electromagnetic component corresponds to the end of the permanent magnetic component, and the magnetism at both ends of the electromagnetic component can be changed.

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The embodiment of the present application discloses a lifting device for electromechanical installation.

[0035] Reference Figure 1 and Figure 2A lifting device for electromechanical installation includes a base 1, a scissor-type telescopic frame 2, and a work platform 3. The work platform 3 is provided with a counterweight 4 and an adjustment component 5 that can drive the counterweight 4 to move arbitrarily in the horizontal direction. During the installation of electromechanical equipment, the position of the counterweight 4 is adjusted to balance the force on the work platform 3, so that the force is balanced, and the weight on one side of the work platform 3 is reduced, thereby reducing the risk of the work platform 3 tipping over and improving the safety of the lifting platform during use.

[0036] Reference Figure 1 and Figure 2 A support assembly 10 is provided on the base 1 to support the lifting device. The support assembly 10 includes a support rod 101 and a rotating rod 102. The support rod 101 is vertically arranged. One end of the rotating rod 102 is rotatably connected to the base 1, and the other end is rotatably connected to the support rod 101. The rotating rod 102 is arranged at intervals along the length direction of the support rod 101. In this embodiment, two rotating rods are arranged so that the support rod 101 can maintain a vertical state during the rotation of the rotating rod 102, so that the support rod 101 is supported on the ground.

[0037] Reference Figure 1 and Figure 2 The support assembly 10 further includes a limit rod 103, and the two ends of the limit rod 103 correspond to the two rotating rods 102. The two ends of the limit rod 103 are fixed to the rotating rod 102 by screws, and the limit rod 103 is set at an angle with the support rod 101, which can also be understood as the limit rod 103 is not parallel to the support rod 101, so that the rotation of the rotating rod 102 can be limited, so that the support rod 101 can be stably supported on the ground to support the lifting device.

[0038] Reference Figure 1 and Figure 3 The working platform 3 is a plate-like structure as a whole, and a guardrail is provided on the side away from the ground to reduce the possibility of workers falling. The adjustment component 5 is arranged below the working platform 3, and the adjustment component 5 includes an adjustment rod 51, which is arranged parallel to the working platform 3, and one end is rotatably connected to the working platform 3. The end of the adjustment rod 51 away from its own rotation axis is defined as a movable end 512, and the end close to its own rotation axis is defined as a fixed end 511. The rotation axis of the adjustment rod 51 coincides with the vertical center line of the working platform 3. The counterweight block 4 is a rotating body structure, and the counterweight block 4 is slidably connected to the adjustment rod 51 along the length direction of the adjustment rod 51. Rotating the adjustment rod 51 can drive the counterweight block 4 to rotate, and sliding the counterweight block 4 can make it close to or away from the vertical center line of the working platform 3, so that the counterweight block 4 can move to any position within the range of the length of the adjustment rod 51 as a radius. The force on the working platform 3 is adjusted.

[0039] Reference Figure 3 and Figure 4 The side of the counterweight 4 close to the adjusting rod 51 is provided with a sliding groove 52, which penetrates in a direction parallel to the length of the adjusting rod 51, and the adjusting rod 51 is inserted in the sliding groove 52, so as to achieve sliding cooperation between the counterweight 4 and the sliding groove 52. Two clamping grooves 53 are provided on the two side walls of the adjusting rod 51 parallel to its own length and perpendicular to the ground, and the clamping grooves 53 are penetrated in the length direction of the adjusting rod 51. A clamping block 54 is provided on the side wall of the sliding groove 52 corresponding to the clamping groove 53, one side of the clamping block 54 is welded to the side wall of the sliding groove 52, and the other end extends into the clamping groove 53, so as to prevent the counterweight 4 from moving downward, so as to achieve a stable connection between the counterweight 4 and the adjusting rod 51.

[0040] Reference Figure 3 and Figure 4 The adjustment assembly 5 also includes a driving rod 55, which is arranged below the adjustment rod 51 in a direction parallel to the adjustment rod 51. One end of the driving rod 55 away from the movable end 512 extends to the other side of the rotation axis of the adjustment rod 51. The driving rod 55 is rotatably connected to the adjustment rod 51, and a avoidance groove 56 is provided on the side of the sliding groove 52 close to the ground, and the avoidance groove 56 penetrates in a direction parallel to the length of the driving rod 55. A threaded groove that cooperates with the thread on the driving rod 55 is provided on the side wall of the avoidance groove 56. Rotating the driving rod 55 can drive the counterweight 4 to move, thereby adjusting the position of the counterweight 4.

[0041] Reference Figure 5 and Figure 6 The working platform 3 is provided with a driving assembly 6 for driving the adjusting rod 51 or the driving rod 55 to rotate. The driving assembly 6 includes an abutment member 61 and a driving member 62. The abutment member 61 includes a rotating shaft 611 and a friction disc 612. The rotating shaft 611 is vertically arranged and is connected to the working platform 3 by rotating around its own axis. An accommodating chamber 63 is provided inside the adjusting rod 51, and the end of the rotating shaft 611 close to the ground extends into the accommodating chamber 63. The friction disc 612 is located in the accommodating chamber 63, and the friction disc 612 is coaxially fixedly connected to the end of the rotating shaft 611 close to the ground. The rotating shaft 611 can slide in the vertical direction, and the sliding rotating shaft 611 can connect the friction disc 612 with the adjusting rod 51 or with the driving rod 55. The driving member 62 is used to drive the rotating shaft 611 to rotate. In this embodiment, the driving member 62 is a servo motor. The housing of the servo motor is fixedly connected to the working platform 3, and the output shaft of the servo motor is slidably matched with the rotating shaft 611. During the use of the lifting equipment, the friction disk 612 is disconnected from the adjusting rod 51 and the driving rod 55. When the weight on the working platform 3 is unevenly distributed, the adjusting rod 51 or the driving rod 55 can be driven to rotate by sliding the rotating shaft 611 to adjust the position of the counterweight block 4.

[0042] Reference Figure 5 and Figure 6 When the rotating shaft 611 moves upward, the side of the friction disc 612 facing away from the ground abuts against the side of the accommodating chamber 63 away from the ground, and the friction disc 612 can drive the adjusting rod 51 to rotate under the action of friction. A linkage assembly 7 is arranged below the friction disc 612, and the linkage assembly 7 includes a rotating member 71 and a transition member 72. The rotating member 71 is a disc-shaped structure, which is connected to the accommodating chamber 63 by rotating around its own axis. A first bevel gear 73 is arranged at the end of the driving rod 55, and is connected to the rotating member 71 and the first bevel gear 73 through the transition member 72 to realize transmission. When the rotating shaft 611 moves downward, the friction disc 612 can abut against the rotating member 71. Under the action of friction, the friction disc 612 can drive the rotating member 71 to rotate, thereby driving the driving rod 55.

[0043] Reference Figure 5 and Figure 6 The transition piece 72 is composed of two truncated cones, and the large ends of the two truncated cones are integrally formed. A second bevel gear 74 is arranged below the rotating piece 71. A tooth groove meshing with the second bevel gear 74 is provided on the side wall of the truncated cone of the transition piece 72 facing away from the ground. A tooth groove meshing with the first bevel gear 73 is provided on the side wall of the truncated cone of the transition piece 72 close to the ground, so as to realize the linkage between the rotating piece 71 and the driving rod 55.

[0044] Reference Figure 5 and Figure 6 The two end surfaces of the friction disk 612 are provided with guide surfaces 75, and the sides of the two guide surfaces 75 that are away from each other are inclined in the direction close to the axis of the friction disk 612. The rotating member 71 and the side wall of the accommodating cavity 63 are provided with corresponding embedded grooves, so that the end of the friction disk 612 can be inserted into the embedded groove, and the friction disk 612 can be guided to be inserted into the embedded groove through the guide surface 75, thereby improving the stability of the connection between the friction disk 612 and the adjustment rod 51 or the rotating member 71.

[0045] Reference Figure 5 and Figure 6 , a limit assembly 8 is provided on the adjusting rod 51, and the limit assembly 8 includes an abutting rod 81 and an elastic member 82. The abutting rod 81 is rotatably connected to the adjusting rod 51, and one end of the abutting rod extends into the embedded groove on the adjusting rod 51, and the other end abuts on the working platform 3. The elastic member 82 is installed on the adjusting rod 51, and is used to make the abutting rod 81 maintain the tendency of driving the abutting end to rotate in the direction close to the working platform 3. When the friction disc 612 is embedded in the embedded groove on the adjusting rod 51, it can drive the abutting rod 81 to rotate, so that the abutting rod 81 is away from the working platform 3, and the limit on the rotation of the adjusting rod 51 is cancelled. After the friction disc 612 is disengaged from the embedded groove on the adjusting rod 51, the abutting rod 81 automatically resets, limits the rotation of the adjusting rod 51, and improves the stability of the driving rod 55 in the process of rotating.

[0046] Reference Figure 5 and Figure 6 The working platform 3 is provided with a mode conversion component 9 for controlling the sliding of the rotating shaft 611. The mode conversion component 9 includes an electromagnetic component 91 and two permanent magnet components 92. The permanent magnet component 92 is an annular structure. The two permanent magnet components 92 are slidably sleeved on the rotating shaft 611 along the length direction of the rotating shaft 611. The electromagnetic component 91 is arranged between the two permanent magnet components 92, and the two ends of the electromagnetic component 91 fixedly connected to the working platform 3 have opposite magnetic poles. The magnetic poles of the ends of the two permanent magnet components 92 that are close to each other are the same. The electromagnetic component 91 can change the magnetic poles at both ends according to the flow direction of the current passing through itself, and can drive the rotating permanent magnet component 92 to move under the action of the magnetic field force, thereby realizing the control of the movement of the rotating shaft 611 and the adjustment of the position of the friction disk 612.

[0047] Reference Figure 5 and Figure 6 The electromagnetic component 91 mainly includes an iron core and a coil wound outside the iron core. A fixing frame 93 is arranged outside the iron core, and the iron core is fixedly connected to the adjustment rod 51 through the fixing frame 93. During the use of the lifting device, the rotating shaft 611 is affected by gravity, so that the rotating shaft 611 has a tendency to move downward. Therefore, a certain current is maintained in the coil under normal conditions to overcome the gravity on the rotating shaft 611.

[0048] Reference Figure 5 and Figure 6 A detection system 11 is arranged between the working platform 3 and the scissor-type telescopic frame 2. The detection system 11 includes a support platform 112 and a gravity sensor 111. The support platform 112 is arranged in parallel and spaced below the working platform 3. The gravity sensor 111 is arranged between the support platform 112 and the working platform 3. The two ends of the gravity sensor 111 are respectively connected to the support platform 112 and the working platform 3 to support the working platform 3. There are four gravity sensors 111, and the four gravity sensors 111 are distributed in a rectangular shape on the horizontal plane. The two mutually perpendicular directions of the working platform 3 on the horizontal plane are defined as the first direction and the second direction. In the actual detection process, the industrial computer can make judgments based on the data measured by the gravity sensor 111, and then control the adjustment of the position of the counterweight 4 by controlling the drive member 62 and the electromagnetic member 91.

[0049] The specific judgment method of industrial computer is as follows: The four gravity sensors 111 are respectively a first sensor, a second sensor, a third sensor and a fourth sensor. The first sensor and the second sensor are arranged at intervals along the first direction, the third sensor and the fourth sensor are arranged at intervals along the first direction, the first sensor and the third sensor are arranged at intervals along the second direction, and the second sensor and the fourth sensor are arranged at intervals along the second direction.

[0050] S1, obtain the readings of the first sensor and the second sensor, define the distance between the first sensor and the second sensor as L, define the vertical distance between the weight and the first sensor in the first direction as X, then the reading G1 of the first sensor and the reading G2 of the second sensor satisfy the following relationship, G1*X=G2*(LX), and X can be calculated immediately.

[0051] S2, obtain the third sensor reading G3, define the distance between the weight and the first sensor in the second direction as Y, then the reading G1 of the first sensor and the reading G3 of the second sensor satisfy the following relationship G1*Y=G3*(LY), and Y can be obtained immediately.

[0052] S3, determine the position of the weight through X and Y. After the position of the weight is determined, the direction in which the counterweight 4 needs to move can be determined. The force on the working platform 3 is balanced by adjusting the position of the counterweight 4 so that the readings of the first sensor, the second sensor and the third sensor tend to be equal.

[0053] The implementation principle of a lifting device for electromechanical installation in an embodiment of the present application is: by adjusting the position of the counterweight block 4, the overall force on the working platform 3 is balanced, thereby reducing the weight on one side of the lifting device, which may cause the lifting device to tip over.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
