Description

Technical Field

[0001] The present application relates to the field of section steel processing devices, and in particular to an H-section steel end painting device. Background Art

[0002] After the H-shaped steel is processed, the operator needs to use a handheld spray gun to spray paint the end surface of the H-shaped steel so that the end surface of the H-shaped steel is covered with a layer of paint, thereby achieving the purpose of protecting the end surface of the H-shaped steel and reducing the occurrence of rust on the H-shaped steel. The handheld spray gun includes a spray gun body and a paint canister mounted on the spray gun body, and the paint canister is filled with paint. Since it is usually necessary to spray multiple H-shaped steels at one time during painting, and the handheld spray gun is heavy, the operator holds the spray gun body for a long time to work, which puts a certain burden on the operator's body and leads to high labor intensity for the operator.

A bottom plate, a support plate, a slide plate, and a supporting plate are sequentially arranged below the paint canister from bottom to top. A plurality of rollers are mounted on the bottom plate. A vertically arranged hydraulic cylinder is mounted on the bottom plate. The telescopic rod of the hydraulic cylinder is fixed to the support plate. The slide plate is slidably connected to the upper surface of the support plate. The support plate is also provided with a drive assembly for driving the slide plate to move.

[0006] The slide plate is connected with a support rod, the upper end of the support rod is fixed to the supporting plate, and the supporting plate is also provided with a fixing component for fixing the paint canister.

[0007] By adopting the above technical solution, the operator places the paint gun body and the paint canister on the pallet, and uses the fixing assembly to fix the paint canister, so that the paint gun body can also be fixed, and pushes the base plate to move the paint gun body to the predetermined position, and then controls the hydraulic cylinder to work, and the telescopic rod of the hydraulic cylinder drives the support plate, the slide plate, the support rod, the support plate and the paint gun body to move in the height direction until the paint gun body moves to the appropriate height, and then starts the paint gun body to spray the end face of the H-shaped steel. During the spraying process, the operator controls the driving assembly to work, so that the slide plate, the support rod, the support plate and the paint gun body move along the length direction of the base plate, so that H-shaped steel at different positions can be sprayed; by controlling the operation of the hydraulic cylinder, the height position of the paint gun body can be changed, and H-shaped steel at different heights can be sprayed; the situation where the operator needs to continuously hold the paint gun when spraying H-shaped steel is reduced, thereby reducing the labor intensity of the operator.

When the paint spray gun body reaches a suitable angle, the rotating motor is turned off.

[0020] Optionally, the diameter of the driving gear is smaller than the diameter of the transmission gear.

[0021] By adopting the above technical solution, the driving gear rotates multiple times to drive the transmission gear to rotate one circle, so that the operator can better control the rotation angle of the paint spray gun body.

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application discloses an H-beam end spraying device. Figure 1 , including a base plate 1, the lower surface of the base plate 1 is rotatably connected to a plurality of rollers 11, a hydraulic cylinder 2 is installed on the upper surface of the base plate 1, the telescopic rod of the hydraulic cylinder 2 is set upward, and the upper end of the telescopic rod of the hydraulic cylinder 2 is fixedly connected to a support plate 3 parallel to the base plate 1, and the length directions of the support plate 3 and the base plate 1 are consistent; a slide plate 4 is provided above the support plate 3, and a driving component 5 for driving the slide plate 4 to slide along the length direction of the support plate 3 is also provided on the upper surface of the support plate 3.

[0031] The driving assembly 5 includes a lead screw 51 and a guide rod 52 rotatably connected to the upper surface of the support plate 3. The lead screw 51 and the guide rod 52 are arranged along the width direction of the support plate 3. The lead screw 51 and the guide rod 52 are parallel to each other, and the axial directions of the lead screw 51 and the guide rod 52 are arranged along the length direction of the support plate 3; the lead screw 51 passes through the slide 4 and is threadedly engaged with the slide 4, the guide rod 52 passes through the slide 4 and is slidably plugged into the slide 4, and a driving motor 53 is also installed on the support plate 3 at one end of the lead screw 51, and the output shaft of the drive motor 53 is coaxial with the lead screw 51 and fixed.

[0032] The drive motor 53 drives the screw 51 to rotate, and the screw 51 cooperates with the guide rod 52 to enable the slide 4 to slide along the length direction of the support plate 3. By changing the rotation direction of the output shaft of the drive motor 53, the rotation direction of the screw 51 can be changed, thereby changing the forward direction of the slide 4.

[0033] Reference Figure 1 and Figure 2 The skateboard 4 is rotatably connected to a support rod 6, and the upper end of the support rod 6 is fixedly connected to a support plate 7. The paint spray gun is placed on the support plate 7. The skateboard 4 is also provided with a rotating assembly 8 for controlling the rotation of the support rod 6. The rotating assembly 8 includes a rotating motor 81 fixedly connected to the upper surface of the skateboard 4, and the output shaft of the rotating motor 81 is arranged upward; a coaxial driving gear 82 is fixedly connected to the output shaft of the rotating motor 81, and a transmission gear 83 coaxial with the support rod 6 is fixedly connected to the support rod 6. The transmission gear 83 meshes with the driving gear 82, and the diameter of the transmission gear 83 is larger than the diameter of the driving gear 82.

[0034] The rotating motor 81 drives the driving gear 82 to rotate, and the driving gear 82 rotates for multiple cycles to drive the transmission gear 83 to rotate for one cycle. The transmission gear 83 rotates to drive the support rod 6, the support plate 7 and the paint spray gun to rotate, so that the paint spraying angle of the paint spray gun can be adjusted according to actual conditions. Since the driving gear 82 rotates for multiple cycles to drive the transmission gear 83 to rotate for one cycle, the operator can control the paint spraying angle of the paint spray gun more accurately.

[0035] The paint spray gun includes a paint spray gun body 10 and a paint canister 101 installed on the paint spray gun body 10. A fixing assembly 9 for fixing the paint canister 101 is provided on the support plate 7; the fixing assembly 9 includes two side plates 91 fixedly connected to the upper surface of the support plate 7, and horizontally arranged connecting rods 92 are slidably inserted on the two side plates 91. The ends of the two connecting rods 92 close to each other are fixedly connected to a fixing plate 93, and the side walls of the two fixing plates 93 close to each other are arc surfaces adapted to the paint canister 101. The ends of the two connecting rods 92 away from each other are fixedly connected to an anti-slip plate 94, and a spring 95 is sleeved on the connecting rod 92 and located between the fixing plate 93 and the side plate 91. The fixing plate 93 and the side plate 91 are both fixed with the spring 95.

[0036] The operator pushes the two fixing plates 93 away from each other, the fixing plates 93 move and compress the spring 95, and then places the paint canister 101 on the support plate 7 so that the paint canister 101 is located between the two fixing plates 93, and then releases the fixing plates 93, the spring 95 recovers its deformation and pushes the fixing plates 93 to move until the fixing plates 93 abut against the paint canister 101; the two fixing plates 93 cooperate to clamp and fix the paint canister 101, thereby fixing both the paint canister 101 and the paint gun body 10 on the support plate 7.

[0037] After the paint canister 101 is fixed to the paint spray gun body 10, the base plate 1 is moved to one end of the H-shaped steel, and the length direction of the base plate 1 is aligned with the arrangement direction of the H-shaped steel. The hydraulic cylinder 2 is controlled to work, and the telescopic rod of the hydraulic cylinder 2 drives the support plate 3, the support rod 6, the support plate 7 and the paint spray gun body 10 to move until the paint spray gun body 10 moves to a predetermined height; the rotating motor 81 is controlled to work, and the painting angle of the paint spray gun body 10 is adjusted until the paint spray gun body 10 rotates to a suitable angle, and finally the rotating motor 81 is turned off.

[0038] When the height and the paint spraying angle of the paint spray gun body 10 are at appropriate positions, the drive motor 53 is controlled to work, so that the slide plate 4, the support rod 6, the support plate 7 and the paint spray gun body 10 move along the base plate 1. By changing the rotation direction of the output shaft of the drive motor 53, the slide plate 4 and the paint spray gun body 10 can be moved back and forth along the base plate 1, so that the end faces of the H-shaped steel at different positions can be sprayed; the need for the operator to continuously hold the paint spray gun when spraying the H-shaped steel is reduced, thereby reducing the labor intensity of the operator.

[0039] The implementation principle of an H-shaped steel end paint spraying device in an embodiment of the present application is as follows: pushing the fixed plate 93 in a direction away from each other, the fixed plate 93 moves to compress the spring 95, then placing the paint canister 101 on the supporting plate 7, loosening the fixed plate 93, the spring 95 restores its deformation and pushes the fixed plate 93 to move, so that the two fixed plates 93 cooperate to fix the paint canister 101; controlling the hydraulic cylinder 2 to work so that the paint spray gun body 10 moves to a suitable height, controlling the rotating motor 81 to work so that the paint spray gun body 10 rotates to a suitable angle, and then controlling the driving motor 53 to work so that the slide plate 4 and the paint spray gun body 10 move back and forth along the bottom plate 1.
