Description

Technical Field

[0001] This invention belongs to the field of rail transit technology, specifically a rail transit power box and its auxiliary installation components. Background Technology

[0002] In the field of rail transit, the installation and positioning of traditional power boxes mostly rely on manual calibration, which has a low level of intelligence, makes it difficult to adapt to the installation requirements of different specifications of rail vehicles, and is prone to insufficient installation accuracy due to positioning deviation, thus failing to meet the high precision and high stability installation requirements of rail transit equipment.

[0003] Patent application number CN201821897340.9 discloses an auxiliary installation device for a power box in rail transit, relating to the field of rail transit technology. It includes a box body, with sliding grooves on both the left and right sides of the inner wall of the box. Sliding blocks are installed within the sliding grooves, and the opposing faces of the two sliding blocks are fixedly connected to the left and right sides of a placement plate, respectively. This auxiliary installation device for a power box in rail transit, through the cooperation of an electric push rod, a placement plate, sliding blocks, sliding grooves, a buffer pad, a clamping plate, and a first fixing plate, allows the power box to be pulled forward and removed after the sliding groove contacts the inner wall of the groove and the placement plate is flush with the front side of the box body. This avoids manual operation during lifting and transportation of the power box, prevents collisions with other objects during transport, reduces safety hazards for workers and the power box, and thus ensures efficient installation of the power box to a certain extent.

[0004] While existing auxiliary installation equipment can mitigate collision risks associated with manual operation and improve foundation installation efficiency to some extent, it lacks a lifting force detection and balancing adjustment structure. This means it cannot avoid installation problems caused by uneven lifting forces and lacks an effective buffer and protection structure to offset potential energy impacts during installation. Therefore, in order to solve the above-mentioned technical problems, the present invention proposes a rail transit power box and its auxiliary installation components for the device. Summary of the Invention

[0005] The purpose of this invention is to address the above problems by providing a rail transit power box and its auxiliary installation components, which have the advantages of intelligent detection and balanced adjustment of hoisting force and intelligent calibration of installation positioning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rail transit power box, comprising a box assembly, wherein a plurality of lifting ring assemblies for installation and fixing are connected to one end of the box assembly, the box assembly includes an upper frame, the lifting ring assemblies are connected to the upper frame, a support rod is connected to the end of the upper frame away from the lifting ring assemblies, a bottom plate is provided on the side of the support rod away from the upper frame, and a protective rod for vibration buffering is connected between the bottom plate and the support rod; The lifting ring assembly includes a lifting ring for connection, the lifting ring abutting against the surface of the upper frame, a connecting rod connected to one end of the lifting ring near the base plate, a plurality of buffer pads slidably disposed on the periphery of the connecting rod, and the connecting rod being slidably connected to the upper frame.

[0007] Preferably, the lifting ring assembly further includes a connecting spring for resetting the lifting ring, the two ends of the connecting spring distributed along the length direction are respectively connected to the end of the connecting rod and the upper frame, and an elastic rod for shock absorption is connected to the end face of the buffer pad, and a plurality of buffer pads are evenly distributed along the axial direction of the connecting rod.

[0008] Preferably, the housing assembly has a power chamber and a heat dissipation chamber respectively, and a partition for separating the space is connected between the power chamber and the heat dissipation chamber.

[0009] Preferably, the upper frame is provided with heat dissipation holes and air outlets, wherein the air outlets are connected to the power chamber, the heat dissipation holes are connected to the heat dissipation chamber, and a pad for protecting and stabilizing the contact is also connected to the end face of the upper frame.

[0010] Preferably, the cushioning pad is made of rigid plastic, rubber, or other materials with protective properties.

[0011] The present invention also includes an auxiliary installation assembly for a rail transit power box, comprising a plurality of abutment components for installation protection, wherein the plurality of abutment components are uniformly connected to the base plate, and the end face of the abutment component is flush with the end face of the base plate. The abutment component includes a telescopic rod, one end of which is connected to the base plate, and the end of the telescopic rod away from the base plate is connected to a contact part for contact with the outside world.

[0012] Preferably, the contact portion includes a support plate, one end of which is connected to the telescopic rod, and the end of the support plate away from the telescopic rod is connected to a hinge rod for changing the connection angle. The end of the hinge rod away from the support plate is connected to an abutment plate, and a protective cover for protecting the hinge rod is connected between the abutment plate and the support plate.

[0013] Preferably, each of the support rods is connected to a positioning component for assisting installation. The positioning component includes a crossbar, one end of which is connected to the support rod. The end of the crossbar away from the support rod is rotatably provided with a swing rod, and the side of the swing rod away from the crossbar is connected to a plurality of sector plates.

[0014] Preferably, the swing arm and the crossbar are connected vertically in space.

[0015] Preferably, the end of the swing rod away from the crossbar is connected to a fixed rod, and multiple rotating rods are evenly distributed on the circumference of the fixed rod. The ends of the multiple rotating rods away from the fixed rod are connected to multiple sector plates.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The protective rods and pads of the lifting ring assembly and the housing assembly work together. During hoisting, the connecting rods slide on the upper frame as the lifting ring is subjected to force. Displacement sensors detect the movement data of each connecting rod. When the force is uneven, the buffer pads and elastic rods offset the excessive force through elastic deformation. The connecting springs simultaneously achieve reset and tension buffering, and can also supplement the height of the lifting ring to maintain the level of the housing. At the same time, when the bottom plate contacts the railcar, the protective rods elastically compress to offset the potential energy impact, and the pads isolate the railcar from direct contact with the upper frame. This not only realizes intelligent detection and balanced adjustment of the hoisting force through component linkage, but also comprehensively reduces the impact and deformation risks during the hoisting and installation process, thereby improving hoisting safety.

[0017] 2. The telescopic rod and contact part of the contact component work together with the intelligent control module. When the box descends, the contact component first contacts the railcar. The stroke sensor of the telescopic rod and the angle sensor of the hinge rod detect the stroke difference and tilt angle deviation respectively. When the data exceeds the threshold, the intelligent control module simultaneously sends a fine-tuning command to the hoisting equipment and a calibration command to the positioning component.

[0018] 3. The system is interconnected with the horizontal bar, swing bar, sector plate, and contact component. When the contact component detects a deviation, the intelligent control module adjusts the angle of the sector plate according to the pre-stored track vehicle parameters by controlling the angle adjustment motor of the swing bar. When the installation space is small, the sector plate forms a conical column to reduce alignment resistance. At the same time, the contact sensor of the sector plate detects the contact pressure. When the pressure exceeds the threshold, the tilt angle is finely adjusted to avoid hard contact deformation. When the pressure is stable, a precise engagement is determined. Meanwhile, the elastic arc block of the track vehicle's limiting groove engages and limits the sector plate. The linkage between the components achieves intelligent alignment, multi-condition adaptation, and precise fixing, ensuring the accuracy and stability of the power box installation.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 - Figure 5As shown, this invention discloses a rail transit power box, including a box assembly 1 for connection with a railcar. Multiple lifting ring assemblies 3 for installation and fixation are connected to one end of the box assembly 1. During installation, the box assembly 1 is hoisted onto the railcar and connected to the lifting ring assemblies 3 via a hoisting device. The box assembly 1 includes an upper frame 101 for component connection, with the lifting ring assemblies 3 connected to the upper frame 101. A support rod 102 for providing support strength is connected to the end of the upper frame 101 away from the lifting ring assemblies 3. A base plate for protection is provided on the side of the support rod 102 away from the upper frame 101. 103, namely support rod 102, is located between upper frame 101 and base plate 103. At the same time, a barrier is also connected between upper frame 101 and base plate 103 to protect the components between upper frame 101 and base plate 103. A protective rod 104 for vibration buffering is connected between base plate 103 and support rod 102. During the hoisting of the power box, when base plate 103 comes into contact with the railcar body, the contact force between base plate 103 and railcar body increases, causing elastic compression of protective rod 104, realizing stable descent of power box, and reducing deformation of railcar body and power box caused by potential energy impact during installation.

[0023] In use, the lifting device is connected to the lifting ring assembly 3, so that the lifting device can lift the lifting ring assembly 3 and move the box assembly 1 in sync, so that the box assembly 1 can move to the target installation area of ​​the railcar. At the same time, during the installation process, when the base plate 103 contacts the body of the railcar, the protective rod 104 is used to buffer and maintain the stable movement of the box assembly 1, reducing the impact potential energy during the installation of the power box.

[0024] In this design, the preferred number of lifting ring assemblies 3 is four, evenly distributed around the upper frame 101. Each lifting ring assembly 3 includes a lifting ring 301 for connection, which abuts against the surface of the upper frame 101. One end of the lifting ring 301 near the base plate 103 is connected to a connecting rod 302 for connection and restriction. Multiple buffer pads 303 are slidably provided on the periphery of the connecting rod 302 to suppress its movement speed. The connecting rod 302 is slidably connected to the upper frame 101. Based on the movement distance of the connecting rod 302 on the upper frame 101, it is determined whether the force on each lifting ring 301 is uniform, and the lifting position of the lifting ring 301 is adjusted in time. At the same time, when the lifting device applies force to the lifting ring 301, the lifting ring 301 drives the connecting rod 302 to move relative to the upper frame 101, and simultaneously drives the buffer pad 303 to move relative to the connecting rod 302, thereby ensuring that the force on the lifting ring 301 rises in a linear state, ensuring the smooth rise of the box assembly 1, and improving the safety during lifting.

[0025] Furthermore, to ensure the safety and stability of the lifting ring 301 during hoisting, the lifting ring assembly 3 also includes a connecting spring 305 for resetting the lifting ring 301 and the connecting rod 302. The two ends of the connecting spring 305 distributed along the length direction are respectively connected to the end of the connecting rod 302 and the upper frame 101. An elastic rod 304 for shock absorption and buffering of impact force is connected to the end face of the buffer pad 303. Multiple buffer pads 303 are evenly distributed along the axial direction of the connecting rod 302.

[0026] Furthermore, before the housing assembly 1 is lifted while the lifting ring 301 is under force, the force on the lifting ring 301 is identified by judging the movement of the buffer pad 303 and the connecting rod 302, thereby adjusting the contact position on the lifting ring 301 in a timely manner. At the same time, the buffer pad 303 is used to suppress the movement speed of the connecting rod 302 and neutralize the force between the four lifting rings 301, ensuring that the force state between the four lifting rings 301 is relatively stable.

[0027] Specifically, when the force on one side of the lifting ring 301 is greater than the force on the other three sides of the lifting ring 301, the moving length of the connecting rod 302 on the side with greater force is greater than the moving length of the connecting rods 302 on the other three sides. This causes the buffer pad 303 and the elastic rod 304 to cancel out the force on the lifting ring 301, ensuring the connection safety of the lifting ring 301.

[0028] Meanwhile, when the lifting ring 301 is subjected to uneven force, it is very easy for the end face of the upper frame 101 to tilt, which increases the difficulty of installing the power box. Therefore, according to the different force conditions of the lifting ring 301, the interaction between the connecting rod 302, the buffer pad 303, the elastic rod 304 and the connecting spring 305 is used to supplement the height of the lifting ring 301, so that the lifting ring 301 can still maintain the horizontal angle stability of the box assembly 1 even under uneven force, thus improving the installation efficiency of the power box.

[0029] It should be noted that, in order to ensure that the buffer pad 303 can meet the requirements of supplementing the force on the lifting ring 301 and constraining the movement path of the connecting rod 302, the material of the buffer pad 303 is composed of rigid plastic, rubber or other materials with protective effects.

[0030] To improve the detection of force on the lifting ring assembly 3, a displacement sensor is installed on the connecting rod 302. The displacement sensor is electrically connected to an external intelligent control module. The displacement sensor is used to detect the moving distance and moving speed of the connecting rod 302 relative to the upper frame 101 in real time. The intelligent control module receives the detection data from the displacement sensors of each lifting ring assembly 3 and sets the control variables as the difference in moving distance and the difference in moving speed of the connecting rod 302.

[0031] Specifically, when the difference in the moving distance of any two connecting rods 302 exceeds a preset threshold or the difference in the moving rate exceeds a preset threshold, the intelligent control module issues an early warning signal and sends an adjustment command to the lifting equipment to control the lifting equipment to adjust the lifting tension of the corresponding lifting ring 301 until the difference in the moving distance and the difference in the moving rate of each connecting rod 302 are within the preset threshold range, thereby achieving intelligent and balanced adjustment of the lifting force.

[0032] Furthermore, the housing assembly 1 is provided with a power cavity 4 for providing power and a heat dissipation cavity 5 for installing other components. A partition 6 for separating the space is connected between the power cavity 4 and the heat dissipation cavity 5 to ensure that the space between the power cavity 4 and the heat dissipation cavity 5 will not interfere with each other.

[0033] Furthermore, the upper frame 101 is provided with heat dissipation holes 1011 and air outlets 1012 respectively. The air outlets 1012 are connected to the power chamber 4, and the heat dissipation holes 1011 are connected to the heat dissipation chamber 5. A pad 2 for protecting the contact stability is also connected to the end face of the upper frame 101. The pad 2 is used to protect the housing assembly 1, ensuring that the shell of the railcar will not directly act on the upper frame 101, thereby improving the connection safety of the housing assembly 1.

[0034] During the hoisting process, the hoisting device is connected to the lifting ring assembly 3 evenly distributed around the upper frame 101. After the lifting ring 301 is subjected to the lifting tension, it drives the connecting rod 302 to slide along the upper frame 101, and simultaneously pulls the box assembly 1 to move as a whole to the target installation area of ​​the railcar. When the base plate 103 comes into contact with the railcar body, the contact force causes the protective rod 104 to generate elastic compression. The elastic deformation offsets the potential energy impact during the descent of the power box, and avoids deformation of the railcar body and the box assembly 1 due to hard contact. At the same time, the pad 2 is attached to the end face of the upper frame 101, isolating the railcar shell from direct contact with the upper frame 101, and further improving the connection safety of the box assembly 1.

[0035] During the sliding process of the connecting rod 302 under tension, the buffer pads 303 evenly distributed around its periphery slide relative to the connecting rod 302. The elastic rod 304 connected to the end face of the buffer pad 303 simultaneously undergoes elastic deformation, effectively suppressing the sliding rate of the connecting rod 302. At the same time, the two ends of the connecting spring 305 are connected to the end of the connecting rod 302 and the upper frame 101 respectively, providing a reset force for the lifting ring 301 and the connecting rod 302, and also offsetting part of the lifting tension through its own elastic deformation.

[0036] When the force on one side of the lifting ring 301 is greater than that on the other lifting rings 301, the sliding length of the connecting rod 302 on that side will be greater than that on the other sides. At this time, the buffer pad 303 and the elastic rod 304 offset the excessive force through double elastic buffering. At the same time, the elastic deformation is used to supplement the height of the lifting ring 301 on that side. Even under uneven force, the horizontal angle of the box assembly 1 can still be maintained, avoiding the increase in installation difficulty caused by the tilt of the upper frame 101. Moreover, the buffer pad 303 not only satisfies the constraint on the movement path of the connecting rod 302, but also effectively supplements the force on the lifting ring 301, ensuring the stability and safety of the lifting process.

[0037] like Figure 6 - Figure 10 As shown, the present invention also includes an auxiliary installation component for a rail transit power box, comprising multiple abutment components 7 for protecting the box assembly 1 during installation. The multiple abutment components 7 are evenly connected to the base plate 103. When the base plate 103 approaches the installation position, the abutment components 7 first contact the body of the railcar. At the same time, a stroke sensor is set on the abutment component 7. The contact status of the abutment component 7 is determined by analyzing the movement length of the abutment component 7. Furthermore, the end face of the abutment component 7 can be flush with the end face of the base plate 103 to ensure the stable installation of the box assembly 1.

[0038] That is, during the process of the lifting device and lifting ring assembly 3 moving and installing the box assembly 1, the contact component 7 first contacts the body of the railcar to ensure the stability of the contact area of ​​the contact component 7 and realize the stable descent of the box assembly 1.

[0039] The abutment assembly 7 includes a telescopic rod 701 for stable movement of the housing assembly 1. A spring is connected inside the telescopic rod 701. One end of the telescopic rod 701 is connected to the base plate 103. The end of the telescopic rod 701 away from the base plate 103 is connected to a contact part 702 for contact with the outside. At the same time, the contact part 702 can be completely retracted into the base plate 103, that is, the end of the contact part 702 away from the base plate 103 is flush with the end of the base plate 103.

[0040] Furthermore, to ensure stable contact between the contact part 702 and the railcar body, the contact part 702 includes a support plate 7021. One end of the support plate 7021 is connected to the telescopic rod 701. The end of the support plate 7021 away from the telescopic rod 701 is connected to a hinge rod 7024 for changing the connection angle. The end of the hinge rod 7024 away from the support plate 7021 is connected to an abutment plate 7023. A protective cover 7022 is connected between the abutment plate 7023 and the support plate 7021 to protect the hinge rod 7024. The protective cover 7022 has an elastic function, so when the angle between the abutment plate 7023 and the support plate 7021 deflects, the protective cover 7022 will not protect the hinge rod 7024.

[0041] Specifically, during the contact process between the contact plate 7023 and the railcar body, when the contact plate 7023 is in complete contact with the target area, the contact plate 7023 and the bearing plate 7021 are parallel to each other, and the axial direction of the hinge rod 7024 is perpendicular to the contact plate 7023 and the bearing plate 7021. When the contact plate 7023 deviates from the target area, the force angle of the contact plate 7023 tilts, which causes the angle between the contact plate 7023 and the hinge rod 7024 to deflect. At this time, the lowering angle of the box assembly 1 is adjusted in time according to the deflection state of the contact plate 7023.

[0042] Meanwhile, an angle sensor is installed on the hinge rod 7024. Both the angle sensor and the stroke sensor are electrically connected to the intelligent control module. The control variable of the intelligent control module is set to the difference between the tilt angle deviation of the contact plate 7023 and the stroke of the telescopic rod 701. When the angle sensor detects that the tilt angle deviation of the contact plate 7023 relative to the bearing plate 7021 exceeds the preset threshold, or when the stroke sensor detects that the stroke difference of each telescopic rod 701 exceeds the preset threshold, the intelligent control module sends a calibration command to the positioning component 8, controls the positioning component 8 to adjust the angle and position, and sends a fine-tuning command to the hoisting equipment to adjust the descent angle and position of the box assembly 1, thereby realizing intelligent calibration of the installation contact.

[0043] Furthermore, each support rod 102 is connected to a positioning component 8 for auxiliary positioning and installation. In this scheme, the number of support rods 102 is preferably four, that is, distributed at the four corners of the upper frame 101 and the base plate 103. The positioning component 8 includes a crossbar 801 for length extension. One end of the crossbar 801 is connected to the support rod 102. The end of the crossbar 801 away from the support rod 102 is rotatably provided with a swing rod 802 for angle fine adjustment. However, it should be noted that the swing rod 802 and the crossbar 801 are vertically connected in space. The side of the swing rod 802 away from the crossbar 801 is connected to a plurality of fan-shaped plates 805 for engaging with the limiting groove on the railcar body.

[0044] An angle adjustment motor is installed at the rotational connection between the swing rod 802 and the crossbar 801, and an angle adjustment motor is installed at the connection between the fixed rod 803 and the rotating rod 804. Both the angle adjustment motor and the angle adjustment motor are electrically connected to the intelligent control module. The intelligent control module controls the alignment deviation angle between the sector plate 805 and the limiting groove, the specifications of the railcar body, and the dimensions of the installation space. The intelligent control module pre-stores the specification data of the limiting groove and the dimensions of the installation space for different railcar bodies. Based on the detected alignment deviation angle, the angle adjustment motor drives the swing rod 802 to rotate, and at the same time, the angle adjustment motor drives the rotating rod 804 to change the angle of the sector plate 805. When the installation space dimension is less than the preset value, the sector plate 805 is controlled to form a conical column structure to reduce the alignment resistance. When the alignment deviation angle is less than the preset threshold, the adjustment stops, thus realizing the intelligent alignment and multi-condition adaptation of the positioning component 8.

[0045] During use, the swing rod 802 is kept perpendicular to the mounting end face of the railcar. Based on the contact condition of the contact plate 7023, it is determined whether the sector plate 805 corresponds to the limiting groove. The relative rotation between the swing rod 802 and the crossbar 801 is controlled, causing the swing rod 802 to drive the sector plate 805 to deflect, so that the traveling end of the sector plate 805 can correspond to the limiting groove. As the housing assembly 1 continues to move, the traveling end of the sector plate 805 extends into the limiting groove. As the housing assembly 1 continues to descend, the rotation angle of the swing rod 802 is adjusted back. The interaction force between the sector plate 805 and the limiting groove is used to adjust the installation position of the housing assembly 1, so that the sector plate 805 can completely correspond to the limiting groove, thus completing the installation of the housing assembly 1.

[0046] Meanwhile, during the relative movement between the sector plate 805 and the limiting groove, the movement and positioning of the sector plate 805 are detected by the deflection state of the contact plate 7023, so as to achieve accurate positioning of the box assembly 1.

[0047] It should be noted that the wall of the limiting groove on the railcar body is ring-shaped and is composed of multiple arc blocks, which are elastically connected to each other. Thus, after the sector plate 805 passes through the limiting groove, the tail end of the sector plate 805 can be engaged to prevent the box assembly 1 from moving.

[0048] To ensure safety when the sector plate 805 contacts the limiting groove, a contact sensor is added to the sector plate 805. The contact sensor is electrically connected to the intelligent control module, and the control variable of the intelligent control module is set to the contact pressure between the sector plate 805 and the limiting groove.

[0049] When the contact sensor detects that the contact pressure between the sector plate 805 and the limiting groove exceeds the preset threshold, the intelligent control module controls the tilt adjustment motor to finely adjust the tilt angle of the sector plate 805, reduce the contact pressure, and prevent the sector plate 805 and the limiting groove from deforming due to hard contact. At the same time, when the contact pressure stabilizes within the preset range, it is determined that the sector plate 805 has completed precise engagement and sends a positioning completion signal to the intelligent control module.

[0050] Furthermore, the end of the swing rod 802 away from the crossbar 801 is connected to a fixed rod 803 for support. Multiple rotating rods 804 for changing the tilt angle of the sector plate 805 are evenly distributed on the circumference of the fixed rod 803. The ends of the multiple rotating rods 804 away from the fixed rod 803 are connected to the multiple sector plates 805. That is, during the process of connecting and fixing the housing assembly 1, the tilt angle of the sector plate 805 is changed by the rotating rods 804, so that the shape of the sector plate 805 forms a conical column, thereby reducing the relative force when the sector plate 805 slides relative to the limiting groove, and avoiding deformation. At the same time, after the housing assembly 1 is installed, the tilt angle of the sector plate 805 is kept unchanged. When the housing assembly 1 needs to be lifted again, the angle of the sector plate 805 is returned by the rotating rods 804, so that the sector plate 805 is parallel to the axis of the fixed rod 803, so that the sector plate 805 can move and be pulled out within the limiting groove.

[0051] During the installation and positioning of the power box, the auxiliary installation component completes the process. The abutment component 7 of this component is evenly connected to the base plate 103. When the box assembly 1 descends and approaches the installation position, the abutment component 7 contacts the railcar body before the base plate 103. During the contact process, the telescopic rod 701 undergoes telescopic deformation due to the contact force. The stroke sensor installed inside it transmits the telescopic stroke data to the intelligent control module. At the same time, the angle sensor on the hinge rod 7024 detects the change in the tilt angle of the abutment plate 7023 relative to the bearing plate 7021 in real time, so as to achieve accurate judgment of the installation contact state.

[0052] When the contact plate 7023 is fully in contact with the target installation area of ​​the railcar, the contact plate 7023 and the bearing plate 7021 are parallel to each other, and the axis of the hinge rod 7024 is perpendicular to both. If a contact deviation occurs, the contact plate 7023 will tilt under force, causing the hinge rod 7024 to deflect at an angle. At this time, if the tilt deviation value detected by the angle sensor or the travel difference value of the telescopic rod 701 detected by the travel sensor exceeds the preset threshold, the intelligent control module will immediately send a calibration command to the positioning component 8 and a fine-tuning command to the hoisting equipment, and simultaneously adjust the lowering angle and position of the box component 1 to achieve intelligent calibration of the installation contact. The protective cover 7022 has an elastic function and can still protect the hinge rod 7024 when the angle deflects, avoiding external impurities from affecting the hinge fit accuracy.

[0053] The positioning component 8 and the contact component 7 work together to achieve precise positioning of the housing component 1. The crossbar 801 extends in length, and the swing rod 802 is perpendicularly connected to the crossbar 801 in space. An angle adjustment motor is installed at the joint where the two rotate. An angle adjustment motor is installed at the joint where the rotating rod 804 connects to the fixed rod 803. Both the angle adjustment motor and the angle adjustment motor are electrically connected to the intelligent control module. The intelligent control module pre-stores the specification data of the limit groove and the installation space size data of different railcar bodies. Using the alignment deviation angle between the fan-shaped plate 805 and the limit groove, the railcar body specification parameters and the installation space size parameters as control variables, the intelligent alignment and multi-condition adaptation of the positioning component 8 are realized.

[0054] After the contact component 7 detects the installation contact deviation and sends a calibration command, the intelligent control module controls the angle adjustment motor to drive the swing rod 802 to rotate relative to the crossbar 801, causing the sector plate 805 to deflect at an angle, so that the traveling end of the sector plate 805 corresponds to the limiting groove of the railcar body. At the same time, according to the installation space size parameters, if the installation space size is less than the preset value, the tilt angle adjustment motor drives the rotating rod 804 to change the tilt angle of the sector plate 805, so that multiple sector plates 805 form a conical column structure, reducing the alignment resistance with the limiting groove, and making it easier for the sector plate 805 to extend into the limiting groove.

[0055] As the housing assembly 1 continues to descend, after the traveling end of the sector plate 805 extends into the limiting groove, the intelligent control module controls the rotation angle of the angle adjustment motor return swing rod 802. By utilizing the interaction force between the sector plate 805 and the limiting groove, the installation position of the housing assembly 1 is precisely adjusted until the sector plate 805 and the limiting groove are completely aligned.

[0056] The contact sensor added to the sector plate 805 uses the contact pressure between the sector plate 805 and the limiting groove as the control variable. When the contact sensor detects that the contact pressure exceeds the preset threshold, it controls the tilt angle adjustment motor to finely adjust the tilt angle of the sector plate 805 to reduce the contact pressure and prevent the sector plate 805 and the limiting groove from deforming due to hard contact. When the contact pressure stabilizes within the preset range, it is determined that the sector plate 805 has completed precise engagement and sends a positioning completion signal to the intelligent control module. At this time, the housing assembly 1 achieves precise positioning and completes the installation operation.

[0057] When the power box needs to be disassembled, the control tilt adjustment motor drives the rotating rod 804 to move the sector plate 805 back to its original position, so that the sector plate 805 is parallel to the axis of the fixed rod 803, and the clamping constraint of the limit groove arc block on the sector plate 805 is released. Then, the lifting equipment is controlled to pull the lifting ring assembly 3, and the connecting rod 302 slides in the opposite direction along the upper frame 101 under the reset force of the connecting spring 305, and the lifting ring 301 returns to its initial position.
