Description

Technical Field

[0001] The utility model relates to a spray gun replacement device. Background Art

[0002] Originally, after the spray gun 1A was fixed, two double-rod cylinders 2A were connected to the support plate. An air inlet pipe 4A and a gun head sleeve 5A were fixed on the support plate 3A. When the cylinders extended, the gun head sleeve was sleeved on the gun for sealing. However, when there was a problem with the air source of the cylinders, the gun could not be replaced (as shown in Figure 1 the figure). Content of the Utility Model

[0003] The purpose of the utility model is to provide a spray gun replacement device, which makes it easy to replace the spray gun when a problem occurs.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A spray gun replacement device, comprising a lift seat, a power group, two lead screws, a gun lifting frame, an air inlet pipe and a gun head sleeve. The power group is installed on the lift seat. The power group includes a worm and worm gear device and a driving member. The driving member is drivingly connected to the worm. The worm meshes with two worms. Each worm is provided with an axial nut. The nut is screwed to a vertical lead screw. The lower ends of the two lead screws are connected to the gun lifting frame. The air inlet pipe is installed on the lift seat and is located between the two worms.

[0006] Preferably, the driving members are respectively installed at both ends of the worm. One end is a hand wheel, and the other end is a motor, a pneumatic or a hydraulic motor.

[0007] Preferably, both ends of the gun lifting frame are respectively hinged to the lower ends of the lead screws by pins. A U-shaped clamp for positioning the spray gun is provided in the middle of the gun lifting frame. A ferrule corresponding to the U-shaped clamp is provided on the spray gun.

[0008] The beneficial effects of the utility model: In the utility model, the spray gun moves, and the air inlet pipe can be connected to a hard pipe. In the traditional structure, the spray gun does not move, and the air inlet pipe can only be connected to a metal hose. The hose is easily damaged due to frequent movement. In the traditional structure, the gun cannot be replaced when there is a problem with the air source of the cylinders. However, the gun can be manually replaced when a problem occurs in this device. This device can quickly replace the gun in combination with a gun replacement frame, greatly saving the gun replacement time. Description of the Drawings

[0016] The following only uses embodiments to illustrate the possible implementation modes of the present utility model, but is not intended to limit the scope of protection of the present utility model. First, it is stated.

[0017] As Figures 2 to 9 shown, a gun replacement device of the present utility model includes a lift seat 1, a power group, two lead screws 3, a gun lifting frame 4, an air inlet pipe 5 and a gun head sleeve 6. The power group includes a worm and worm gear device 21. The housing of the worm and worm gear device 21 is installed on the lift seat 1. The driving members of the power group are located at both ends of the worm. One end is driven by a handwheel, and the other end is driven by a motor. Both sides of the worm 23 are respectively engaged with the worm wheels 24. The worm wheel is provided with an axial nut, and the nut is screwed to the vertical lead screw 3. The lower ends of the two lead screws 3 are connected to the gun lifting frame 4. The air inlet pipe 5 is installed on the lift seat 1, and the air inlet pipe 5 is located between the two worm wheels.

[0018] Preferably, the driving members are respectively installed at both ends of the worm. One end is a handwheel 221, and the other end is a motor 222, a pneumatic or hydraulic motor. With this dual-power structure, if there is a problem with the motor, pneumatic or hydraulic motor, it can still be manually operated.

[0019] Preferably, both ends of the gun lifting frame are respectively hinged to the lower ends of the lead screws by pins. The middle part of the gun lifting frame is provided with a U-shaped clamp 41 for positioning the spray gun, and the spray gun is provided with a ferrule 42 corresponding to the U-shaped clamp.

[0020] Description of removing the spray gun: As Figures 4 to 6 shown, the power group or the handwheel drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the lead screw to descend. The lead screw is connected to the gun lifting frame to lower the spray gun to disengage from the gun head sleeve, and the spray gun is moved away.

[0021] Description of installing the spray gun: As Figures 7 to 9 shown, the spray gun is hung on the gun lifting frame. The power group or the handwheel drives the worm to rotate, the worm drives the worm wheel to rise the lead screw, the lead screw is connected to the gun lifting frame to raise the spray gun, and the spray gun is inserted into the gun head sleeve for sealing.
