Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a vertical spraying device that increases the degree of freedom in controlling the spraying posture of a spraying pipe during spraying work.

[Prior art]

A conventional vertical spray device has a function of moving a spray pipe forward and backward and a function of rotating it, and is already known by the applicant and others.

However, in this conventional spraying device, in order to tilt the entire spraying pipe, the arm itself to which the spraying pipe is attached is tilted, or the spraying pipe that is pivoted in one axis is rotated. It is difficult to tilt in two axial directions, and the mechanism made possible by combining them is quite complicated, and it is not easy to adjust the tilt angle accurately.

[Purpose of invention]

The present invention aims to provide a vertical spraying device that eliminates these drawbacks.

The term "vertical spraying equipment" in the specification refers to wet-type, dry-type vertical spraying equipment, and vertical spraying equipment used in thermal spraying work using fuel gas, etc., and is mainly used for lining refractories.

[Structure of idea]

This invention is characterized by attaching a biaxially movable swinging mechanism to the tip of a swingable arm, and equipping the swinging mechanism with a pipe advancing/retracting/rotating mechanism that advances, retreats, and rotates a vertical spray pipe. This relates to a spraying device.

〔Example〕

This will be explained below according to the drawings.

Figures 1 to 6 show a first embodiment in which a biaxially movable universal support is provided at the tip of a rotatable and extendable arm, and a vertical spray pipe that can move forward and backward and rotate freely is attached to the universal support. be.

Figures 7 and 8 show a second embodiment in which a biaxially movable universal support is provided on a rotatable and erectable arm, and a vertical blow pipe that can move forward and backward and rotate is attached to the universal support.

That is, in this embodiment, the swing mechanism is comprised of a universal support.

In the figure, 100 is a vertical spray pipe, 200 is a universal support, 300 is an arm for mounting the vertical spray pipe 100, the universal support 200, and its attached members, and 40
0 is a mobile cart equipped with the present vertical spraying device, 500 is a material tank for spraying material, 600 is a water tank, and 700 is a pot.

To explain in more detail, 101 is the spray pipe body, 102
103 is a spray nozzle; 103 is a refractory supply hose; 104 is a spray water supply hose; 105 is a pipe advancing/retracting/rotating mechanism for moving the spray pipe main body 101 back and forth and rotating; 106
is the spray pipe main body 10 in the pipe advancement/retraction/rotation mechanism.
107 is a gear drive unit for rotating the spray pipe main body 101, 108 is a U-shaped guide for preventing rotation of the refractory supply hose 103 and the spray water supply hose 104, and 201 is a universal An outer mounting ring constituting the support portion 200 and the arm 30
0, 202 is an inner mounting ring that is inside the outer mounting ring and is pivoted to the outer mounting ring 201, 203 is the pivot of the outer mounting ring to the arm 300, and 204 is the outer side of the inner mounting ring. Mounting ring 201
205 is a cylinder for rotating the outer mounting ring 202, and 206 is a cylinder having one end pivoted to the rod of the cylinder and the other end fixed to the pivot 203. 207 is a cylinder that rotates the inner mounting ring;
208 is a rotating arm having one end pivotally connected to the rod of the cylinder and the other end fixed to the pivot shaft 204.

Further, 301 is a telescopic arm body to which the outer attachment ring 201 is attached, 302 is a hydraulic cylinder for making the arm body telescopic, 303 is a hydraulic jack for raising the arm body 301 in the second embodiment, 30
4 is a rotary table to which the base end of the arm body 301 is attached, 305
306 is a gear drive mechanism for rotating the rotating table 304, 401 is a wheel of the moving cart 400, and 402 is a rail.

Note that in the first embodiment, the material tank 500 and the water tank 60
0 is not placed on the movable trolley 400 and is installed at a different location, whereas in the second embodiment it is placed on the movable trolley 400 and moves together with the water device.

The pipe advance/retreat rotation mechanism 105 of the vertical spray pipe 100 is not limited to the drive roller 106 and gear drive mechanism 107 as in this embodiment.

Further, the biaxially movable swinging mechanism is not limited to the universal support of this embodiment.

In the present invention, the vertical spray pipe 100 has an advancing/retracting/rotating mechanism 10.
The arm 30 to which the vertical spray pipe 100 is attached can freely spray the inner and outer walls of the pot 700 in either the vertical direction or the circumferential direction by rotating up and down within the pot 700 using the arm 30.
0 rotates, so the spray pipe 10 is vertically attached to the wall of the pot 700.
The position of the vertical spray pipe 100 can be changed by moving 0 closer to or farther away from each other while drawing a circular arc.

Furthermore, the vertical spray pipe 100 has a swinging mechanism (
The universal support 200) in the figure allows the two wheels to tilt forward, backward, left and right, and the spray nozzle 102 of the vertical spray pipe 100 can be easily brought close to and away from the furnace wall, making it easy to secure the necessary spray distance. Even if the shape is complicated, it can be sprayed relatively easily, and the efficiency and accuracy of spraying work can be greatly improved.

Furthermore, in the first embodiment shown in FIGS. 1 to 6, the arm 300 of the vertical spray pipe 100 is extendable and retractable, so that the degree of freedom in operating the vertical spray pipe 100 is increased.

Since the arm 300 of the embodiment shown in FIGS. 7 and 8 can be raised freely, the degree of freedom of operation is similarly high.

Further, as shown in FIGS. 2 and 7, it is preferable to tilt the pan 700 during the spraying operation so that the interior of the furnace can be observed.
can be tilted to match the angle of inclination of the pot 700.

[Effect of idea]

As described above, according to the present invention, a biaxially movable swinging mechanism is attached to the tip of a swingable arm, and a vertical spray pipe that can freely move forward and backward and rotate is attached to the swing mechanism, so that the vertical spray pipe 100 In addition to the degree of freedom in moving forward, backward, and rotating, the entire vertical spray pipe 100 can be rotated, rotated in two axes, and tilted, making it possible to freely adjust the spray distance and to Even if the shape of the pipe is complicatedly curved or when the spraying work is performed by tilting the pan 700, the spraying can be easily performed by rotating the vertical spray pipe 100 in biaxial directions and tilting it.
