Description

Technical Field

[0001] This utility model relates to the field of flange transportation technology, specifically a flange transfer rack. Background Technology

[0002] A flange is a disc-shaped or ring-shaped mechanical fastener with bolt holes. It is an indispensable, standardized, detachable connection element for modern industrial piping and pressure vessels. It provides a reliable, sealed, and robust connection, greatly facilitating system installation, maintenance, and upgrades.

[0003] Patent CN217074442U discloses a flange transfer frame in which the flange is vertically inserted between two sets of fixing and positioning arc plates (8), and the bottom is supported by a staggered plate (6). A spring mechanism (including a telescopic rod, spring, positioning ball, etc.) provides lateral limiting protection. This solution has significant drawbacks: it mainly relies on the spring mechanism to fix the flange side. Long-term use can lead to spring fatigue, telescopic rod jamming, or wear of the rubber ball sleeve, resulting in weakened lateral positioning function. Therefore, frequent maintenance is required, increasing costs. Utility Model Content

[0004] This utility model addresses the aforementioned shortcomings of existing technologies by providing a flange transfer bracket that solves the problem of spring positioning failure caused by long-term use, making it safer and more reliable to use.

[0007] Preferably, the lower end of the placement plate is connected to the transfer vehicle via a rotating shaft, and the back of the placement plate is connected to the transfer vehicle via a support mechanism. The support mechanism includes an arc-shaped support sleeve connected to the vehicle body, and a support rod connected to the bottom of the placement plate is fitted inside the support sleeve. Locking bolts for fixing the support rod are provided on the side wall of the support sleeve.

[0008] Preferably, the placement plate has handles at both ends.

[0009] Preferably, the positioning groove is wider at the top and narrower at the bottom.

[0010] Preferably, a baffle is provided on the inner wall of the positioning groove.

[0011] Preferably, the side wall of the placement plate is provided with a guide post, the end of the guide post is provided with a limiting block, the protective plate is provided with a guide hole that cooperates with the guide post, the front of the placement plate is provided with an upper positioning bolt for pressing down the protective plate, and the back of the placement plate is connected with a lower positioning bolt for pressing up the protective plate.

[0012] Preferably, the two ends of the placement plate are provided with support plates for fixing positioning bolts.

[0013] Preferably, the angle of the placement plate is 15°-45°.

[0014] Preferably, rubber pads are provided on the side walls of the placement plate, positioning groove, and baffle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model completely eliminates elastic dependence, eliminates the risk of fatigue failure, significantly improves long-term stability, allows the flange to naturally adhere to the placement plate under gravity, and the outer edge of the flange is inserted into the bottom of the groove, enhancing vibration resistance and solving the problem of spring positioning failure caused by long-term use, making it safer and more reliable to use.

[0017] 2. This utility model is applicable to flange production lines, assembly workshops, and warehousing and logistics processes. It is especially beneficial for the transfer of large-diameter / irregular flanges, significantly improving efficiency and reducing the risk of collision damage. It solves the problems of unstable positioning, poor specification compatibility, and cumbersome operation in flange transfer, and combines safety, flexibility, and economy.

[0018] 3. This utility model, through an angle-adjustable placement plate, an adjustable-spacing protective plate, and a positioning groove that is wider at the top and narrower at the bottom, enables the transportation of flanges of different sizes and increases their versatility.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 As shown, a flange transfer rack includes a transfer cart 1. The bottom of the transfer cart 1 is equipped with casters with brakes, and a handle is located at one end. An inclined placement plate 4 is connected to the upper end of the transfer cart 1. The angle of the placement plate 4 is adjustable, ranging from 15° to 45°, allowing adjustment of the angle according to flanges 3 of different diameters to ensure the flange 3 is firmly secured against the placement plate 4. Figure 3 As shown, a protective plate 2 is connected to one side of the placement plate 4. The upper end of the protective plate 2 is provided with a positioning groove 202 for fixing the flange 3. The positioning groove 202 is wider at the top and narrower at the bottom, which can position the flange 3 and prevent it from rolling. The distance between the protective plate 2 and the placement plate 4 is adjustable.

[0026] The lower end of the placement plate 4 is connected to the transfer vehicle 1 via a rotating shaft, and the back of the placement plate 4 is connected to the transfer vehicle 1 via a support mechanism 5, as shown below. Figure 2 As shown, the support mechanism 5 includes an arc-shaped support sleeve 503 connected to the vehicle body. A support rod 501 connected to the bottom of the placement plate 4 is fitted inside the support sleeve 503. A locking bolt 502 for fixing the support rod 501 is provided on the side wall of the support sleeve 503.

[0027] Handles 405 are provided at both ends of the placement plate 4 to facilitate manual rotation of the placement plate 4.

[0028] like Figure 4 As shown, a baffle 203 is provided on the inner wall of the positioning groove 202 to further protect the outer side of the flange 3 and ensure that the flange 3 will not fall out of the positioning groove 202. Rubber pads or nylon sheets are provided on the side walls of the placement plate 4, the positioning groove 202 and the baffle 203 to prevent the flange 3 from wearing.

[0029] The side wall of the placement plate 4 is provided with guide posts 402, and the end of the guide posts 402 is provided with a limiting block 401. The protective plate 2 is provided with guide holes 201 that cooperate with the guide posts 402. The front of the placement plate 4 is provided with upper positioning bolts 403 for pressing down the protective plate 2, and the two ends of the placement plate 4 are provided with support plates 404 for fixing the upper positioning bolts 403. The back of the placement plate 4 is connected with lower positioning bolts 406 for pushing up the protective plate 2. After loosening the upper positioning bolts 403 and lower positioning bolts 406 and adjusting the distance between the protective plate 2 and the placement plate 4, the two sides of the protective plate 2 are positioned and fixed by the upper positioning bolts 403 and lower positioning bolts 406. The distance between the protective plate 2 and the placement plate 4 is adjustable, which can accommodate flanges 3 of different thicknesses and improve versatility.

[0030] When in use, adjust the angle of the placement plate 4 according to the diameter of the flange 3, and ensure that the distance between the protective plate 2 and the placement plate 4 is slightly greater than the thickness of the flange 3. This will ensure that the flange 3 can naturally and stably lean against the placement plate 4 under its own weight after being placed on the placement plate 4. The flange 3 is picked up and put down from above the positioning groove 202. During transportation, this will prevent the flange 3 from jumping and rolling, making transportation safe and reliable.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
