A kind of anti-corrosion spraying equipment for inner wall of metal hose

Abstract

The present invention relates to the technical field of pipeline spraying, and in particular to an anti-corrosion spraying device for the inner wall of a metal hose, comprising a winding box and a support table; the winding box is provided with a support table, and the support table is tilted. The first electric push rod drives the mounting ring to move backward, thereby driving the clamping rod to rotate around the sliding rod on the clamping rod. At this time, the spraying rod is still moving backward. When the first electric push rod is reset, the clamping rod and the elastic member will clamp the outer wall of the metal hose, and then the multi-stage push rod will immediately push the moving ring to move forward along the inner wall of the metal hose, and the sliding rod on the clamping rod will move along the track on the spraying rod, so as to avoid the poor effect of manually holding the spraying rod for spraying. After the sliding rod moves to the front end of the track, the nozzle on the spraying rod will leave the metal hose, thereby completing the painting work on the metal hose.

Description

Technical Field

[0001] The invention relates to the technical field of pipeline spraying, and in particular to an anti-corrosion spraying device for the inner wall of a metal hose. Background Art

[0002] In the prior art, when it is necessary to spray paint the inner wall of the metal hose, the worker inserts the spray rod into the metal hose, and then pulls the rope to move the spray rod to the other end of the metal hose, and then starts the power supply to make the spray rod work, and then the worker pulls the spray rod backward to move the spray rod inside the metal hose, thereby spraying paint on the inner wall of the metal hose. When the spray rod moves to the end of the metal hose, the spray rod will lose the support of the inner wall of the metal hose, so it needs to be held by the worker to complete the final painting work on the inner wall of the metal hose. The handheld spray rod is extremely unstable, resulting in extremely poor spraying effect. After the spray rod completes the painting, it is still spraying paint for a short time, which causes the paint to be sprayed on the worker's body and pollutes the air, which may cause the worker to suffer from respiratory diseases and affect the worker's health. At the same time, the prior art is cumbersome and inefficient for spraying paint on the inner wall of the metal hose, and requires the cooperation of multiple workers to operate, thereby increasing labor costs.

[0006] More preferably, a film is provided on the movable groove on each spray rod.

[0007] More preferably, an elastic member is further included; and the movable ends of all clamping rods are fixedly connected with the elastic member.

[0008] More preferably, the limiting assembly includes a limiting rod, a wheel and a spring; a plurality of limiting rods are slidably connected to the spray rod; the upper end of each limiting rod is connected to a wheel via a rotating shaft; each limiting rod is fixedly connected to two springs, and the other end of each spring is fixedly connected to the spray rod.

[0009] More preferably, the clamping assembly includes an electric slide rail and a clamping block; a plurality of electric slide rails in a rectangular array are installed on the support table; and a clamping block is installed on the slider on each electric slide rail.

[0010] More preferably, the side of the clamping block in contact with the metal hose is configured to be arc-shaped.

[0011] More preferably, it further comprises telescopic rods and running wheels; a plurality of telescopic rods are fixedly connected to the front of the spray rod; and the telescopic end of each telescopic rod is rotatably connected to the running wheel via a rotating rod.

[0014] Compared with the prior art, the present invention has the following advantages: the present invention realizes blowing air into the flow channel on the circular plate through the air pipe, and the gas is discharged from the air outlet pipe, thereby generating a backward thrust, thereby pushing the spray rod to move forward along the metal hose. When the nozzle on the spray rod contacts the baffle, the flow channel will stop being inflated, thereby replacing manual labor by pulling the rope to move the spray rod to one end of the metal hose, thereby reducing labor costs and improving work efficiency.

[0015] The first electric push rod drives the mounting ring to move backward, thereby driving the clamping rod to rotate around the sliding rod on the clamping rod. At this time, the spray rod is still moving backward. When the first electric push rod is reset, the clamping rod and the elastic member will clamp the outer wall of the metal hose, and then the multi-stage push rod will immediately push the moving ring to move forward along the inner wall of the metal hose, and the sliding rod on the clamping rod will move along the track on the spray rod, so as to avoid the poor effect of manual hand-held spraying of the spray rod. After the sliding rod moves to the front end of the track, the nozzle on the spray rod will leave the metal hose, thereby completing the painting work of the metal hose;

[0016] By continuously blowing air through the air outlet pipe on the spray rod, the sundries in the metal hose are removed again when the spray rod moves backward along the metal hose. In order to prevent the airflow from affecting the painting work, the fixing assembly can seal the metal hose, thereby improving the use effect of the present invention.

[0017] The space covered by the clamp rod is shielded by the shielding cloth, thereby blocking the paint sprayed from the nozzle, thereby improving the use effect of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] It also includes a baffle 101, a spray rod 201, a circular plate 301, an air outlet pipe 302, a limit assembly, a clamping assembly and a fixing assembly; two baffles 101 are fixedly connected to the front of the support table 2 in a left-right symmetrical manner; a spray rod 201 is rolled up on the winding box 1, and a nozzle 20101 is arranged at the front end of the spray rod 201; three limit assemblies in a circular array are slidably connected to the spray rod 201; a plurality of clamping assemblies are arranged on the support table 2; A fixed assembly; a circular plate 301 is fixedly connected to the rear of the spray rod 201; a flow channel 30101 is opened on the circular plate 301; three air outlet pipes 302 in a circular array are fixedly connected to the rear of the spray rod 201; each air outlet pipe 302 is connected to the flow channel 30101 on the circular plate 301; air is introduced into the flow channel 30101 on the circular plate 301 and then discharged from the air outlet pipe 302, thereby generating thrust, thereby pushing the spray rod 201 to move.

[0031] The fixing assembly includes a fixing ring 202, a multi-stage push rod 203, a moving ring 204, a first electric push rod 205, a mounting ring 206 and a clamping rod 207; a plurality of spray rods 201 are wound on the winding box 1; a fixing ring 202 is fixedly connected to the inner side of the spray rod 201; two multi-stage push rods 203 which are symmetrical on the left and right are fixedly connected to the front side of the fixing ring 202; the telescopic ends of all the multi-stage push rods 203 are fixedly connected to the moving ring 204, and the moving ring 204 is slidably connected to the spray rod 201; two first electric push rods 205 which are symmetrical on the left and right are bolted to the front side of the moving ring 204; the telescopic ends of all the first electric push rods 205 are bolted to the mounting ring 206; four circular arrays are rotatably connected to the mounting ring 206 through the rotating rod 2001 Clamping rod 207; four movable grooves 20102 in a circular array are provided on the spray rod 201, and the clamping rod 207 passes through the corresponding movable grooves 20102; two tracks 20103 are provided on each movable groove 20102; a slide groove 20701 is provided at the front of each clamping rod 207; a slide rod 20702 is slidably connected in each slide groove 20701; the mounting ring 206 is driven to move by contraction of the first electric push rod 205, thereby driving the clamping rod 207 to rotate around the slide rod 20702 on the clamping rod 207, thereby realizing the flipping action of the clamping rod 207, so as to clamp the outer wall of the metal hose 3 through the clamping rod 207, thereby avoiding manual hand-held spraying rod 201, causing the spraying rod 201 to shake and affecting the spraying effect.

[0032] A film is provided on the movable groove 20102 on each spray rod 201 ; when the spray rod 201 sprays the inner wall of the metal hose 3 , the paint is prevented from entering the spray rod 201 from the movable groove 20102 .

[0033] It also includes an elastic member 208 ; the movable ends of all the clamping rods 207 are fixedly connected with the elastic member 208 ; in order to enhance the fixing effect of the clamping rods 207 on the metal hose 3 .

[0034] The limiting assembly includes a limiting rod 401, a wheel 402 and a spring 403; four limiting rods 401 in a circular array are slidably connected to the spray rod 201; the upper end of each limiting rod 401 is connected to the wheel 402 through a rotating shaft; two springs 403 are fixedly connected to each limiting rod 401, and the other end of each spring 403 is fixedly connected to the spray rod 201; after the spray rod 201 is inserted into the metal hose 3, the spring 403 on the limiting rod 401 will shrink under the pressure of the inner wall of the metal hose 3, thereby limiting the mounting ring 206 through the limiting rod 401.

[0035] The clamping assembly includes an electric slide rail 102 and a clamp block 103; a plurality of electric slide rails 102 in a rectangular array are installed on the support table 2; a clamp block 103 is installed on the slider on each electric slide rail 102; the clamp block 103 is driven by the slider on the electric slide rail 102 to move toward each other along the electric slide rail 102, so that the metal hose 3 is fixed on the support table 2 through the clamp block 103.

[0036] The side of the clamping block 103 that contacts the metal hose 3 is configured to be arc-shaped in order to better clamp the metal hose 3 .

[0037] It also includes a telescopic rod 404 and a running wheel 405; three telescopic rods 404 in a circular array are fixedly connected to the front of the spray rod 201; the telescopic end of each telescopic rod 404 is rotatably connected to the running wheel 405 through the rotating rod 2001; the spray rod 201 is limited by the running wheel 405 on the telescopic rod 404, thereby preventing the spray rod 201 from losing support during the rotation of the clamping rod 207.

[0038] In the prior art, when the inner wall of the metal hose 3 needs to be sprayed with paint, first, a worker inserts the spray rod 201 into the metal hose 3, and then pulls the rope to move the spray rod 201 to the other end of the metal hose 3. At this time, the power is turned on to make the spray rod 201 work, and then the worker pulls the spray rod 201 backward to move the spray rod 201 inside the metal hose 3, thereby spraying paint on the inner wall of the metal hose 3. When the spray rod 201 moves to the end of the metal hose 3, the spray rod 201 will lose the inner wall of the metal hose 3. The support of the metal hose 3 is needed, so the worker needs to perform hand-held spraying to complete the final painting work on the inner wall of the metal hose 3. The hand-held spray rod 201 is extremely unstable, resulting in a very poor spraying effect. After the spray rod 201 completes the painting, it is still spraying for a short time, which causes the paint to be sprayed on the worker's body and pollutes the air, which may cause the worker to suffer from respiratory diseases and affect the worker's health. At the same time, the existing technology for painting the inner wall of the metal hose 3 is cumbersome and inefficient, and requires multiple workers to cooperate in the operation, thereby increasing labor costs.

[0039] First, a worker moves the metal hose 3 to be painted onto the support table 2, and then the slider on the electric slide rail 102 drives the clamping block 103 to move toward each other along the electric slide rail 102, so that the metal hose 3 is fixed by the clamping block 103. Figure 1 As shown, at this time, the end of the metal hose 3 away from the winding box 1 will contact the baffle 101. At this time, the spray rod 201 is manually inserted into the metal hose 3, and then the second electric push rod 2002 on the support table 2 will push the table plate on the support table 2 obliquely upward, so that the table plate rotates around the rotating rod 2001 on the support table 2, and then the metal hose 3 is tilted from back to front, so as to facilitate the movement of the spray rod 201 along the metal hose 3, and then the air is blown to the flow channel 30101 on the circular plate 301 through the air pipe, and the gas is discharged from the air outlet pipe 302, thereby generating a backward thrust, thereby pushing the spray rod 201 to move forward along the metal hose 3. When the nozzle 20101 on the spray rod 201 contacts the baffle 101, the flow channel 30101 will stop being inflated, thereby replacing the manual pulling of the rope to move the spray rod 201 to one end of the metal hose 3, thereby reducing labor costs and improving work efficiency.

[0040] It should be noted that after the spray rod 201 enters the metal hose 3, the spring 403 will be in a compressed state.

[0041] It should be noted that the initial state of the first electric push rod 205 is an extended state, and the multi-stage push rod 203 is in an original length state.

[0042] Then, paint is supplied to the nozzle 20101 on the spray rod 201 through the paint supply pipe, so that paint is sprayed out from the nozzle 20101. At this time, the spray rod 201 is reeled up by the reel box 1, so that the spray rod 201 moves backward along the metal hose 3 to spray paint on the inner wall of the metal hose 3. After the spray rod 201 moves to the rear end of the metal hose 3, it continues to move, and the limit rod 401 will be separated from the metal hose 3, thereby releasing the squeezing of the spring 403, and the spring 403 will be reset. The limit rod 401 will move outward under the reset of the spring 403, thereby releasing the limit rod 401 from limiting the mounting ring 206, and then the first electric push rod 205 drives the mounting ring 206 to move backward, thereby driving the clamping rod 207 to move around the sliding Rod 20702 rotates, at this time, the spray rod 201 is still moving backward, when the first electric push rod 205 is reset, the clamping rod 207 and the elastic member 208 will clamp the outer wall of the metal hose 3, and then the multi-stage push rod 203 will immediately push the movable ring 204 to move forward along the inner wall of the metal hose 3, and the slide bar 20702 on the clamping rod 207 will move along the track 20103 on the spray rod 201, so as to avoid the clamping rod 207 clamping the outer wall of the metal hose 3 and affecting the movement of the spray rod 201, thereby avoiding the poor effect of manually holding the spray rod 201 for spraying paint, after the slide bar 20702 moves to the front end of the track 20103, the nozzle 20101 on the spray rod 201 will leave the metal hose 3, thereby completing the painting work of the metal hose 3.

[0043] In order to prevent the spray rod 201 from being offset in the metal hose 3 during the flipping of the clamp rod 207, thereby reducing the spraying effect, the spray rod 201 can be limited by the telescopic rod 404 and the walking wheel 405, thereby improving the use effect of the present invention.

[0044] It should be noted that after the clamping rod 207 and the elastic member 208 clamp the outer wall of the metal hose 3 , the nozzle 20101 on the spray rod 201 is still inside the metal hose 3 .

[0045] Example 2

[0046] On the basis of Example 1, Figure 1 , Figure 4 and Figure 7 As shown, the fixing assembly further includes a shielding cloth 501 ; the shielding cloth 501 is fixedly connected to the outer sides of all the clamping rods 207 .

[0047] The shielding cloth 501 is made of elastic leather material to adapt to the deformation of the clamping rod 207 and enhance the shielding effect of the shielding cloth 501. At the same time, it can also prevent the limiting rod 401 from affecting the movement of the fixed component.

[0048] When the spray rod 201 is spraying the metal hose 3, the rear end of the metal hose 3 can also be closed by the shielding cloth 501 in the fixed component, so as to prevent the paint flying in the air from flying out from the rear end of the metal hose 3, causing the paint to pollute the air and affect the health of the workers, thereby improving the use effect of the present invention.

[0049] After the nozzle 20101 leaves the metal hose 3, the nozzle 20101 will still spray paint for a short time, causing the paint to be sprayed onto the workers, and the paint is not easy to clean. At the same time, it will pollute the air and affect the health of the workers. After the nozzle 20101 leaves the metal hose 3, the nozzle 20101 will be located in the space covered by the clamp rod 207. Therefore, the shielding cloth 501 will be used to shield the space, thereby blocking the paint sprayed from the nozzle 20101, thereby further improving the use effect of the present invention.
