Description

Technical Field

[0001] The invention belongs to the technical field of rail transportation, and in particular relates to an integrated assembly platform of an air duct frame and an assembly method thereof. Background Art

[0002] In the assembly of urban rail subway vehicles, including the pre-assembly of the air duct frame and the installation of the air duct frame, the air duct needs to be pre-assembled on the air duct frame according to the size, and then the pre-assembled air duct frame is hoisted into the installation vehicle. During the hoisting process, multiple people are required to assist in transporting the air duct into the vehicle. The air duct is mainly used for ventilation in the vehicle, and the air duct frame is the installation basis for the entire interior parts of the vehicle. Both are essential installation parts.

[0003] In the prior art, when the air duct is preassembled, it is placed on a pallet for preassembly. Since the pallet is low in height and has poor flatness, the quality and efficiency of the preassembly of the air duct frame are affected. At the same time, the air duct and the air duct frame are large in size and weight. Manual transportation consumes manpower, is inefficient, and has safety hazards. The preassembled air duct frame is easy to deform during the lifting process. Summary of the invention

[0004] In view of the problems in the prior art that the assembly of air duct frames is labor-intensive, inefficient, and has safety hazards, and the pre-assembled air duct frames are easily deformed during lifting, the present invention provides an integrated assembly station for air duct frames and an assembly method thereof, the purpose of which is to: improve the work efficiency and product quality of air duct frame assembly and reduce safety risks during lifting.

[0005] In order to solve the above-mentioned technical problems, the technical solutions adopted by the present invention are as follows:

[0006] An integrated assembly platform for an air duct frame includes a moving frame, a tilting frame, a supporting component and a fixing component.

[0007] The movable frame is hinged with the tilting frame, and the tilting frame is connected with the fixing assembly, and the fixing assembly includes a linkage pressing assembly, and the air duct skeleton is fixed by adjusting the linkage pressing assembly.

[0008] The supporting assembly is disposed on the mobile frame, and the supporting assembly includes an arc-shaped slide rail, in which an arc-shaped slider is slidably connected, and both ends of the arc-shaped slider are respectively connected to the lower end of the tilting frame to keep the tilting frame balanced.

[0009] Universal wheels are arranged under the mobile frame.

[0010] In the present invention, the air duct skeleton is supported by the tilting frame and an assembly platform is provided, which is convenient for assembling the air duct skeleton. The tilting and flipping of the tilting frame is realized by the hinge connection between the tilting frame and the mobile frame, so that it is convenient for passing through a narrow width part and convenient for transportation. In the present invention, the tilting frame is supported by arranging a support assembly, and the tilting frame can be fixed at different tilt angles. The support assembly also supports the tilting frame evenly to prevent damage caused by a large force on one side of the tilting frame. In the present invention, the air duct skeleton can be stably clamped and fixed by the linkage action of the linkage pressing assembly. In the process of rotating and tilting the tilting frame and moving the air duct skeleton driven by the mobile frame, the air duct skeleton is kept stable to prevent the air duct skeleton from being deformed by external force. In the present invention, the universal wheel has a built-in braking function. After the air duct skeleton is transported to the right place, the universal wheel can be fixed to facilitate the removal of the air duct skeleton.

[0011] In the present invention, it should be noted that when an arc-shaped slider is used, the arc of the arc-shaped slider is 180° to maintain support for the tilting frame. No matter what angle the tilting frame is tilted to, the supporting frame will be jointly borne by the two ends of the arc-shaped slider and the hinge with the mobile frame. The weight of the moving frame and the air duct frame is kept in balance, reducing the probability of the air duct frame being deformed by force.

[0012] The present invention preferably provides an integrated assembly station for an air duct skeleton, wherein the arc-shaped slider comprises a first arc-shaped slider and a second arc-shaped slider, a buffering elastomer is connected between the first arc-shaped slider and the second arc-shaped slider, and the buffering elastomer is connected with the first arc-shaped slider and the second arc-shaped slider to form a 180-degree arc.

[0013] After adopting this technical solution, it should be noted that, since the flip angle of the tilt frame is less than 90 degrees, in order to achieve a better supporting effect, the curvature of the first arc slider is smaller than that of the second arc slider, and the curvature of the first arc slider is less than 90 degrees, and the curvature of the second arc slider is greater than 90 degrees, so that the first arc slider and the second arc slider are always located in the arc track. By setting the first arc slider and the second arc slider, it is convenient to set a buffering elastomer to play a buffering and shock absorbing role, thereby reducing the impact and vibration of the arc slider and extending the service life of the device. For example, when one end of the tilt frame receives force or is in the process of tilting, the corresponding arc slider at the end under pressure from the tilt frame transfers force to the buffering elastomer to buffer the pressure, thereby maintaining the stability and balance of the system.

[0014] The present invention preferably provides an integrated assembly station for an air duct frame, wherein the fixing component comprises a movable plate, the linkage pressing component is arranged on the inner side of the movable plate, the movable plate is hinged on the outer side of the tilting frame, and the linkage pressing component presses and fixes the air duct frame.

[0015] After adopting this technical solution, it should be noted that the movable plate provides support for the linked downward pressure assembly. At the same time, when the duct frame needs to be removed, the duct frame will move along the tilting frame. Therefore, the movable plate is hinged to the outer side of the tilting frame. The hinge method can be an existing structure such as a pin shaft and a hinge. When the duct frame is fixed by the downward pressure assembly, the movable plate will also be fixed and will no longer rotate around the hinge point. Therefore, in order to facilitate the disassembly of the duct frame, the movable plate and the tilting frame can be hinged without limit.

[0016] The present invention preferably provides an integrated assembly table for an air duct skeleton, wherein the linkage downward pressure assembly includes an adjusting screw, a main pressure plate and a linkage rod, a support is provided on the inner side of the movable plate, the adjusting screw passes through the support and cooperates with the support thread, the end of the adjusting screw is slidingly connected to the side of one end of the main pressure plate, and the two ends of the main pressure plate are respectively hinged with a linkage rod, and the end of the linkage rod away from the main pressure plate is hinged to the movable plate.

[0017] After adopting this technical solution, it should be noted that when it is necessary to fix the air duct frame, rotate the adjusting screw to move the screw inward, that is, toward the center position of the tilting frame, and the adjusting screw will drive the main pressure plate to move inward. Since both ends of the main pressure plate are hinged with linkage rods, and the end of the linkage rod is hinged to the movable plate, the movement of the main pressure plate will drive the linkage rod to rotate along the hinge point with the movable plate, and the rotation direction is the movement direction of the main pressure plate. This rotation will drive the main pressure plate to move downward in the rotation direction of the linkage rod, thereby achieving fixation of the air duct frame; in the present invention, it should be noted that the main pressure plate extends inward to increase the extrusion and fixing area with the air duct frame.

[0018] The present invention preferably provides an integrated assembly station for an air duct skeleton, wherein a slide groove is provided on the side of one end of the main pressure plate, and a limiting ball is provided at one end of the adjusting screw rod. The limiting ball penetrates into the slide groove and is slidably connected with the slide groove.

[0019] After adopting this technical scheme, it should be noted that, since the main pressure plate will be pressed down under the drive of the linkage rod, a slide groove is set on the side of the main pressure plate, and a limit ball is set at the end of the adjusting screw to cooperate with the limit groove, so that the main pressure plate can move relative to the adjusting screw. In the present invention, the slide groove is located at one end of the main pressure plate close to the adjusting screw, and the cross-section is circular, and the upper and lower end surfaces of the main pressure plate are not penetrated through to prevent the limit ball from slipping off and limit the sliding position of the limit ball; in the present invention, in order to enable the main pressure plate to be pulled back when the adjusting screw rotates in the opposite direction, the diameter of the limit ball is larger than the diameter of the adjusting screw. In the process of rotating the adjusting screw in the opposite direction, it is blocked by the limit ball and will be pulled back to the main pressure plate synchronously; finally, it should be noted that the connection method of the limit ball and the slide groove is adopted. When the adjusting screw is rotated, the rotation and sliding of the limit ball in the slide groove are not restricted, which reduces friction and simplifies the structure.

[0020] The present invention preferably provides an integrated assembly station for an air duct frame, wherein four fixing components are provided, and two of the fixing components are respectively provided at the front end and the rear end of the tilting frame to further fix the air duct frame and ensure the stability of the air duct frame during movement.

[0021] Furthermore, the mobile frame includes a base plate, a first bracket and a second bracket are provided on the base plate, the base plate, the first bracket and the second bracket form an F-shaped frame, the second bracket is provided with a hinge, the hinge is hinged to the tilting frame, a support frame is provided at the lower end of the tilting frame, a fixing portion is provided on the support frame, a limiting hole is provided on the tilting frame, the fixing portion cooperates with the limiting hole for limiting, and the first bracket can support the support frame.

[0022] After adopting this technical solution, it should be noted that the support frame is provided to further support the tilting frame to ensure the stability of the air duct skeleton. The support frame and the tilting frame are detachably connected through the cooperation of the fixing part and the limiting hole, which is convenient for the assembly and transportation of the device, and also convenient for replacing the tilting frame when it is damaged. In the present invention, after the fixing part coincides with the positioning hole, the positioning pin can be inserted into the positioning hole to achieve fixation; in addition, it should be noted that the arc-shaped slide rail is arranged between the first bracket and the second bracket, and is fixedly connected to the first bracket and the second bracket. The arc-shaped slider is a quarter arc, and the universal wheel is arranged at the lower end of the base plate.

[0023] The present invention preferably provides an integrated assembly table for an air duct skeleton, wherein an inclined surface is provided at one end of the support frame away from the first support frame to limit the maximum flipping angle of the tilting frame. The maximum flipping angle is reached when the tilting frame rotates until the inclined surface end of the support frame contacts the bottom plate, thereby preventing the tilting frame from rotating at an excessive angle and rubbing against the bottom surface to cause bumps.

[0024] The present invention preferably provides an integrated assembly station for an air duct frame, wherein a second limiting plate is provided on the upper end of the first bracket, and when the tilting frame is horizontal, one end of the supporting frame is just placed on the first bracket and limited by the second limiting plate.

[0026] After adopting this technical solution, it should be noted that due to the different specifications of the carriages, the sizes of the air duct skeletons are also different. Therefore, the adaptability of the device is increased by setting a telescopic frame. In the present invention, a plurality of telescopic frame limiting holes are provided on the telescopic frame, and corresponding tilting frame limiting holes are provided on the tilting frame. The length of the telescopic frame can be adjusted to a suitable position, and the tilting frame limiting holes and the corresponding telescopic frame limiting holes are overlapped, and fixed by bolts to achieve length adjustment, thereby improving the applicability of the present invention.

[0027] In the present invention, in order to achieve the initial fixation of the assembled air duct frame, the auxiliary pressure plate is set. When the lever is turned, the lever will drive the nut to rotate. In the present invention, the bolt can pass through the nut, so under the cooperation of the thread, the distance between the nut and the auxiliary pressure plate will be reduced, thereby achieving the initial clamping and fixation of the air duct frame.

[0028] The present invention preferably provides an integrated assembly table for an air duct frame, wherein a through slot is penetrated on the arc-shaped slide rail, at least one fixing bolt is arranged in the through slot, the fixing bolt penetrates the first arc-shaped slider and / or the second arc-shaped slider, the fixing bolt extends outward through the through slot, and a nut is arranged on the fixing bolt.

[0029] In the present invention, it should be noted that a threaded hole is opened on the second arc-shaped slider, and the diameter of the threaded hole is consistent with the width of the through groove. The fixing bolt passes through the through hole and cooperates with the threaded hole, and passes out from the other end. When the tilt frame needs to be fixed after being rotated to any angle, the arc-shaped slider can be fixed by tightening the bolts and nuts. It should be noted here that in the present invention, only one arc-shaped slider needs to be fixed to achieve the overall fixation of the tilt frame, and the through groove is an arc that fits the arc-shaped slide rail.

[0030] The present invention preferably provides an integrated assembly platform for an air duct skeleton, wherein an elastic member is connected between the arc-shaped slide rail and the support frame.

[0031] After adopting this technical solution, it should be noted that the elastic member can play a buffering role to prevent the tilting frame from tilting too quickly, causing damage to the air duct frame or a safety accident.

[0032] The present invention preferably provides an integrated assembly platform for an air duct frame, wherein a first limit plate is disposed on the outer side of the telescopic frame, and a buffer pad is disposed on the inner side of the first limit plate.

[0033] After adopting this technical solution, it should be noted that the air duct frame can be limited by the first limiting plate to prevent the air duct frame from sliding to both sides, and the buffer pad can prevent the air duct frame from colliding with the first limiting plate and being damaged.

[0034] The present invention preferably provides an integrated assembly platform for an air duct skeleton, wherein rollers are arranged on the telescopic frame.

[0035] After adopting this technical solution, it should be noted that when the air duct frame is removed, the rollers can facilitate the sliding of the air duct frame, saving manpower.

[0036] An integrated assembly method for an air duct frame comprises the following steps:

[0037] S1. Make the fixing portion coincide with the limiting hole, insert the pin to fix the flip frame on the support frame;
