Description

TECHNICAL FIELD

[0002] Guardrails are mainly used for protecting and preventing personal safety and equipment and facilities in occasions such as residences, highways, construction sites, commercial districts and public places; most guardrail profiles adopt pipe products which are very flexible in assembly, and spraying is a necessary process in the production of guardrail profiles. Spraying is to cover a protective layer or a decorative layer on the surface of metal and non-metal to improve the surface ability, enhance the service life, improve the ability of rust resistance and oxidation resistance and decoration.

[0003] When the surface of a guardrail pipe is painted on the market, the guardrail pipe is usually hung on a paint spraying hanging rail through a hook or a wire, the guardrail pipe is sent into a paint spraying room through the hanging rail to form a flow production; however, the contact part between the pipe and the hook is a spraying blind area and is not sprayed, so that the spraying of the guardrail profile is not comprehensive, and workers often need to re-polish and spray locally, which not only increases the production difficulty, reduces the spraying efficiency, but also increases the production cost and affects the spraying quality. Since the pipe swings greatly during spraying, the pipes are easily collided with each other or even fall off, thereby affecting the spraying quality and working efficiency.

[0004] Another way is to place the guardrail pipe horizontally and provide a connecting piece at both ends of the guardrail pipe, which is very troublesome when hanging, and the conveying is not stable when conveying, the guardrail pipe is easily dropped when the hanging rail is suddenly stopped or fails. Or the guardrail pipe to be sprayed is transversely inserted on the supporting rod of the lifting tool, and then sprayed, but when the pipe to be sprayed is long or heavy, the supporting rod of the lifting tool is easily bent or even causes the pipe to fall off. Another way is to vertically insert the guardrail pipe, but the spraying frame for inserting the guardrail pipe is fixed in position, which makes spraying inconvenient; and multiple products of multiple specifications cannot be sprayed at the same time, the production speed is slow, and the spraying efficiency is poor.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] Example 1

[0030] like Figures 1-3 As shown, a tubular product spraying stand includes a support frame 1 and a clamping mechanism 2. Hooks 3 are provided at both ends of the support frame 1. The entire spraying stand is suspended on a spray paint hanging track through the hooks 3. The spraying stand and the product tube to be sprayed thereon are sent into the spray paint room through the hanging track. A plurality of clamping mechanisms 2 are provided on the support frame 1. When in use, the tube to be sprayed is vertically inserted into the clamping mechanism 2 and clamped by the clamping mechanism 2. The clamping mechanism 2 can rotate along the connection with the support frame 1 and can drive the tube to be sprayed thereon to rotate. In this way, when spraying, if the pressure of the spray gun is sufficient, the tube can be sprayed while rotating, and the spraying is more uniform and of higher quality. Of course, if the pressure of the spray gun is insufficient during spraying, the clamping mechanism 2 does not drive the tube to rotate and does not affect the spraying operation of the tube.

Figures 4-5As shown, the base 4 is rotationally connected with the support frame 1, the limiting plate 5 is welded and fixed on the base 4, the clamping rod 6 is slidingly arranged on the base 4 and is higher than the fixed plate, and the clamping spring 7 is arranged between the clamping rod 6 and the base 4. When installing the pipe to be sprayed, the clamping rod 6 is manually slid so as to be folded with the limiting plate 5, and then the pipe to be sprayed is installed, so that the limiting plate 5 and the clamping rod 6 are inserted into the pipe to be sprayed, at this time, the clamping rod 6 has a resetting tendency under the action of the clamping spring 7, so as to clamp the pipe to be sprayed.

[0032] In addition, when installing the pipe to be sprayed, in addition to manually sliding the clamping rod 6 so as to be folded with the limiting plate 5, the pipe to be sprayed can also be inserted into the rod body part of the clamping rod 6 which is higher than the fixed plate, and then the pipe to be sprayed is pulled to drive the clamping rod 6 to slide towards the limiting plate 5 until the limiting plate 5 can be inserted into the pipe to be sprayed, and then the pipe to be sprayed is controlled to move downward, so as to realize the installation and clamping of the pipe to be sprayed.

[0033] It can be understood that the clamping mechanism 2 described above can clamp pipes of different specifications, and since a plurality of clamping mechanisms 2 are arranged on the support frame 1, the spraying frame provided in the embodiment can simultaneously mount a plurality of products of the same specification or a plurality of products of different specifications.

[0041] Of course, the rotating shaft 11 and the supporting top 12 can be fixedly connected, and the rotating shaft 11 and the flange plate 13 can be threadedly connected.

[0042] Embodiment 4

[0043] The embodiment is further optimization and refinement of the structure on the supporting top 12 based on the embodiment 3, and specifically,

[0044] The supporting top 12 is provided with a limiting plate 5 and a clamping rod 6, the supporting top 12 is a rectangular tube structure, the upper side of one end of the supporting top 12 is provided with a rectangular slide port 14, the opposite end of the slide port 14 is fixedly provided with the limiting plate 5, the clamping rod 6 is clamped in the slide port 14 and can slide along the slide port 14, one end of the supporting top 12 is provided with a baffle 15, the clamping spring 7 is arranged between the baffle 15 and the clamping rod 6, when the clamping rod 6 is moved to the limiting plate 5, the clamping spring 7 exerts a force in the opposite direction on the clamping rod 6, so that the clamping of the pipe to be sprayed can be realized.

[0045] In the embodiment, the slide block 16 is arranged at the lower end of the clamping rod 6, the slide block 16 is clamped in the inner cavity of the supporting top 12, the clamping rod 6 is fixed on the slide block 16 and extends out of the slide port 14, the slide block 16 is slid to drive the clamping rod 6 to slide, the sliding is more reliable, and the clamping spring 7 and the like are more convenient to arrange, the clamping spring 7 is arranged between the baffle 15 and the slide block 16, for example, the two ends of the clamping spring 7 can be fixedly connected with the baffle 15 and the slide block 16 respectively, and the baffle 15 is arranged at the end port of the supporting top 12.

[0046] Embodiment 5

[0047] The embodiment is further optimization and refinement of the structure on the supporting top 12 based on the embodiment 4, and specifically,

[0048] The baffle 15 is provided with a guide rod 17 matched with the clamping spring 7, the sliding block 16 is provided with a guide hole, the guide rod 17 passes through the guide hole, one end of the guide rod 17 passing through the guide hole is provided with a stroke limiting plate 18 to prevent the sliding block 16 from running out of the support top 12, and the clamping spring 7 is sleeved on the guide rod 17 between the baffle 15 and the sliding block 16, so that the clamping spring 7 can accurately provide a linear spring force to prevent the clamping spring 7 from being transversely bent when the clamping rod 6 slides.

[0049] In the embodiment, two clamping springs 7 are arranged between the baffle 15 and the sliding block 16, and the two clamping springs 7 are respectively located at two ends of the sliding block 16 and are hidden in the inner cavity of the support top 12. Correspondingly, the guide rod 17 is also provided with two guide rods. The two clamping springs 7 make the sliding of the sliding block 16 and the clamping of the clamping rod 6 more reliable.

[0050] Embodiment 6

[0051] The embodiment is further optimization and refinement of the structure of the clamping mechanism 2 based on the embodiment 5, and specifically:

[0052] The limiting plate 5 is a right-angle plate, the clamping rod 6 is a round rod, and the right angle of the limiting plate 5 is arranged opposite to the clamping rod 6. When the pipe to be sprayed is clamped, the limiting plate 5 and the clamping rod 6 are respectively clamped on a pair of opposite angles of the pipe. On the one hand, the pipe can be quickly fixed by limiting the pipe with the right-angle plate, and on the other hand, the diagonal line of the pipe to be sprayed is parallel to the cross beam 8 of the support frame 1 in the initial state. In this case, the pipe to be sprayed can be maximally oriented to the spray gun, improving the spraying efficiency. The pipe is sprayed by setting the spray gun on one side of the pipe, and the spraying is completed twice. In another case, the pipe to be sprayed can be maximally oriented to the spray gun in the initial state, which is more convenient for driving the pipe to rotate during spraying, so that the spraying is completed once, further improving the efficiency.

[0053] Embodiment 7

[0054] The embodiment is further optimization and refinement of the structure of the support frame 1 based on the embodiment 6, and specifically:

[0055] The support frame 1 includes two cross beams 8 and a plurality of longitudinal beams 19. The two cross beams 8 are oppositely arranged and connected and fixed by the plurality of longitudinal beams 19. A plurality of mounting holes are longitudinally arranged on the cross beam 8, and the mounting holes on the two cross beams 8 are staggered, so that the spraying of each other does not affect each other, ensuring that each pipe can be uniformly sprayed. The longitudinal beams 19 at both ends of the support frame 1 are respectively provided with lifting hooks 3, and at least two lifting hooks 3 are arranged on each longitudinal beam 19, which is convenient for stable suspension.

[0056] When the spraying frame and all the pipes on it are sent into the spraying chamber for spraying, of course, one of the cases is that the pipe can easily rotate with the clamping mechanism 2 during the installation of the pipe or the conveying into the spraying chamber, in this case, the requirement that the diagonal line of the pipe is parallel to the crossbeam 8 of the support frame 1 when the pipe is installed does not need to be considered; the other case is that the pipe only rotates under the pressure of the spray gun, so when the pipe is installed, the diagonal line of the pipe is parallel to the crossbeam 8 of the support frame 1 as much as possible, so that the pipe has a larger spraying surface in the initial state of spraying, and has sufficient driving force to drive it to rotate more easily. Of course, if the pipe is particularly small or particularly heavy, it will not rotate under the pressure of the spray gun, so only two times of spraying are needed, and the pipe can be turned over by rotating the clamping mechanism 2 in between. The above is for the case of single-sided spray gun spraying, if double-sided spray gun spraying is adopted, the pipe only needs to be installed to the spraying frame and then sent into the spraying chamber for spraying.

[0057] The utility model greatly promotes the placing quantity of the pipes on the assembly line in unit space, and effectively improves the powder spraying powder rate.

[0058] In addition, in the description of the utility model, unless otherwise specified, the meaning of the terms "multiple", "multiple", "multiple groups" is two or more than two, and the meaning of "several", "several", "several groups" is one or more than one. In the description of the utility model, it is necessary to explain that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "internal", "external" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawing, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are used for description only and cannot be understood as indicating or implying relative importance.

[0059] The specific embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range of ordinary skilled persons in the art without departing from the purpose of the utility model.
