Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to multi-angle steel bridge spraying equipment. Background Art

[0002] Cable tray is a common cable protection equipment, usually made of cold-rolled steel as the main material, formed by bending, and needs to be sprayed with plastic and heat-dried before leaving the factory.

[0003] In the current bridge production workshop, the bridge is mainly sprayed by a reciprocating sprayer. The bridge blank is sent to the sprayer through a suspended conveyor belt. The nozzle of the sprayer reciprocates up and down under the drive of the servo displacement mechanism to spray the bridge blank. There are some functional deficiencies in the actual use process, and there is room for improvement. For example, the nozzles of the reciprocating sprayers currently on the market are mostly fixed angles, and spraying is performed straight up and down, while the bridge itself is a bent component with a "concave" cross-section. The inward bent corner is prone to spraying blind spots, which require workers to manually re-spray, which is more troublesome and does not have the function of adjusting the spraying angle.

A nozzle is fixedly connected to one side of the movable tube. A rubber hose is movably connected between one side of the inside of the fixed tube and one side of the nozzle.

[0008] Preferably, the threads inside the sliding platform match the threads outside the threaded drive rod, and the sliding platform can slide up and down along the outside of the sliding rod.

[0009] Preferably, the top end of the paint dispensing chamber is connected to a paint pumping pipe, and the paint pumping pipe, the paint dispensing chamber, the rubber hose, and the interior of the nozzle are interconnected.

[0010] Preferably, the fixed tube and the movable tube are hinged, and a damping gasket is provided at the connection position between the fixed tube and the movable tube.

[0011] Preferably, both sides of the front top of the outer shell are fixedly connected to fixed platforms, one side of the top of the fixed platform is installed with a PLC controller, one side of the PLC controller is fixedly connected with a buzzer, and one side of the bottom of the fixed platform is installed with a dust sensor.

[0012] Preferably, the top of the dust sensor is connected to the bottom of the PLC controller, and the buzzer, PLC controller and dust sensor are electrically connected.

[0013] Preferably, a fixing plate is fixedly connected at the middle position of both sides of the top of the outer shell, a first roller seat is fixedly connected to one side of the top of the fixing plate, two groups of first guide rollers are movably connected to both sides of the inside of the first roller seat, a second roller seat is fixedly connected to the other side of the top of the fixing plate, a second guide roller is movably connected to one side of the inside of the second roller seat, and a paint tube groove is provided on one side of the bottom of the fixing plate.

[0014] Preferably, the fixing plates are symmetrically distributed about the vertical center line of the outer shell, the inner diameter of the paint tube groove is larger than the outer diameter of the paint pumping pipe, the paint pumping pipe passes through the outer shell and the interior of the paint tube groove and extends to the outside, and the outer shell and the paint pumping pipe are not connected.

[0015] Compared with the existing technology, the beneficial effects of the present invention are: the multi-angle steel bridge spraying equipment not only realizes the function of adjustable spraying angle, but also realizes the function of excessive dust reminder and the function of guiding the upper and lower pipes;

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 A multi-angle steel bridge spraying device also includes a spray head assembly, which includes a paint distribution chamber 10. The paint distribution chamber 10 is fixedly connected to the middle position of one side of the sliding platform 9. One side of the paint distribution chamber 10 is fixedly connected to four groups of fixed pipes 11. One side of the fixed pipe 11 is movably connected to a movable pipe 12. One side of the movable pipe 12 is fixedly connected to a nozzle 14. A rubber hose 13 is movably connected between one side of the interior of the fixed pipe 11 and one side of the nozzle 14.

[0028] The internal threads of the sliding platform 9 match the external threads of the threaded drive rod 7. The sliding platform 9 can slide up and down along the outside of the sliding rod 8. The top of the paint dispensing chamber 10 is connected to the paint pump inlet pipe 2. The paint pump inlet pipe 2, the paint dispensing chamber 10, the rubber hose 13, and the interior of the nozzle 14 are connected. The fixed pipe 11 and the movable pipe 12 are hinged. The connection position of the fixed pipe 11 and the movable pipe 12 is provided with a damping gasket, which can realize multi-angle spraying.

[0029] Specifically, if Figure 1 、 Figure 2 and Figure 4 As shown, the paint enters the paint distribution chamber 10 along the paint pump pipe 2, passes through four groups of fixed pipes 11 to the rubber hose 13, and is then sprayed out from the nozzle 14 to form a fine powder mist. According to the actual size and bending amplitude of the bridge, the spraying angle of the nozzle 14 can be changed. The direction of the nozzle 14 can be changed by swinging the movable pipe 12 on the fixed pipe 11 to one side. There is a damping gasket between the fixed pipe 11 and the movable pipe 12 to keep their angles relatively fixed.

[0030] Embodiment 2: A fixing platform 16 is fixedly connected to both sides of the top of the front end of the outer shell 1, a PLC controller 18 is installed on one side of the top of the fixing platform 16, a buzzer 17 is fixedly connected to one side of the PLC controller 18, and a dust sensor 19 is installed on one side of the bottom end of the fixing platform 16. The top end of the dust sensor 19 is connected to the bottom end of the PLC controller 18. The buzzer 17, the PLC controller 18, and the dust sensor 19 are electrically connected, which can remind workers to take protective measures when dust dispersion exceeds the standard;

[0031] Specifically, if Figure 1 and Figure 3 As shown, when the dust sensor 19 senses that the dust amount exceeds the standard, the PLC controller 18 drives the buzzer 17 to operate according to the feedback value, and the buzzer 17 sounds to remind the staff to take protective measures.

[0032] Embodiment 3: A fixed plate 20 is fixedly connected to the middle positions of both sides of the top of the outer shell 1, and a first roller seat 21 is fixedly connected to one side of the top of the fixed plate 20. Two groups of first guide rollers 22 are movably connected to both sides of the inside of the first roller seat 21. A second roller seat 24 is fixedly connected to the other side of the top of the fixed plate 20, and a second guide roller 25 is movably connected to one side of the inside of the second roller seat 24. A paint pipe groove 23 is provided on one side of the bottom of the fixed plate 20. The fixed plate 20 is symmetrically distributed about the vertical center line of the outer shell 1. The inner diameter of the paint pipe groove 23 is larger than the outer diameter of the paint pump inlet pipe 2. The paint pump inlet pipe 2 passes through the outer shell 1 and the interior of the paint pipe groove 23 and extends to the outside. The outer shell 1 and the paint pump inlet pipe 2 are not connected, which can limit the up and down path of the pipeline.

[0033] Specifically, if Figure 1 and Figure 5 As shown, the first guide roller 22 on the first roller seat 21 and the second guide roller 25 on the second roller seat 24 limit the position of the paint pump into the paint pipe groove 23, so that it can stably move up and down, is not prone to swinging or scratching, and extends the service life of the pipe.

[0034] Working principle: When the present invention is in use, first, the steel bridge blank is transported by a suspended conveyor belt into the interior of the outer shell 1, and the external paint pump continuously pumps the spray paint along the paint pumping pipe 2. The paint enters the paint distribution chamber 10 along the paint pumping pipe 2, passes through four groups of fixed tubes 11 to the rubber hose 13, and is then sprayed out from the nozzle 14 to form a fine powder mist. The spraying angle of the nozzle 14 can be changed according to the actual size and bending amplitude of the bridge. The direction of the nozzle 14 can be changed by swinging the movable tube 12 on the fixed tube 11 to one side. There is a damping gasket between the fixed tube 11 and the movable tube 12 to keep their angles relatively fixed. The servo motor 5 drives the sliding table 9 to move up and down through the threaded drive rod 7, so that the upper and lower parts of the bridge are evenly sprayed. As the sliding table 9 and the paint distribution chamber 10 move up and down, the paint pump tube 2 also moves up and down synchronously. The first guide roller 22 on the first roller seat 21 and the second guide roller 25 on the second roller seat 24 limit the position of the paint pump tube 2 at the paint tube groove 23, so that it can move up and down stably and is not prone to swinging or scratching, thereby extending the service life of the tube. Since bridge spraying is electrostatic spraying, the paint is a fine powder. When the spraying pressure is too high, or with the operation of the suspended conveyor belt, the bridge blank is easily entrained by air flow, and some of the powder can easily drift toward the front end of the outer shell 1 along the airflow. When the dust sensor 19 senses that the dust level exceeds the standard, the PLC controller 18 drives the buzzer 17 to operate according to the feedback value. The buzzer 17 sounds to remind the staff to take protective measures.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
