Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an automatic pole polishing device that is applied before painting metal poles such as lighting poles and traffic light poles used on roads.

Conventional technology The metal poles used on roads have been used for nine years, and as a result, they have peeled off and become rusty, so as part of their maintenance, they are sanded and repainted. However, since this type of pole is as high as 10 to 15 meters, a special machine that can be lifted and lowered by a worker is used for the polishing work, but the installation of this machine is limited by the location. This is said to be a drawback, and even if a working machine is used, the polishing work is performed by a worker, so the work efficiency is extremely low.

Points to be Solved by the Invention The main object of the invention is to provide an automatic pole polishing device that can automatically polish poles without using any special working machine or without the help of a worker. This is the purpose.

Another object of the present invention is to provide an automatic pole polishing operation that can smoothly follow and polish a tapered pole whose diameter gradually decreases.

Means for Solving the Problem The pole self-polishing MCl7 M device according to the present invention is composed of a polishing mechanism section for polishing a pole set upright, and a moving mechanism section that moves along the pole with the polishing mechanism section. The polishing mechanism is configured such that two sets of endless running polishing belts, which are in contact with each other with the pole in between, rotate around the pole completely while running by a planetary gear movement mechanism. A plurality of wheels held at a central corner portion, a lever mechanism that mutually engages the wheels with VC delay,
It consists of a weight body attached to a lever mechanism to press the wheel onto the pole surface via a lever machine W, and a wheel drive motor mounted on the lever mechanism, and polishes the pole surface. The operation is natural, and automatic polishing work can be performed by firmly holding the pole and moving the entire device up and down along the pole from the front.

When the wheels (27b) (28b) of 29) are rotated by the t-motor (47), the moving mechanism section (B) moves along the pole CP along with the polishing mechanism section (A). In the moving mechanism part (B), wheels (27a) (Z7b), (
28a) The angle of the lever (28b) that connects to the wheel (2) changes in response to changes in the pole diameter, and the angle with respect to lever r311 is adjustable, so a force that lowers the wheel holder is applied. The force is exerted by the total weight of the weight box Ca, and the total weight causes the lower wheels (27b) (28b) to be placed in a dense layer on the pole surface. It acts as a force to make people feel better. Furthermore,
When the diameter of the pole CP) becomes smaller, the telescopic lever ω(
The wheel (2), which is supported by one lever of (b), is displaced to follow the reduction in the diameter of the pole by the action of the spring (41).

, ) (28a) (28b) is guided along the arcuate track plate (48) to reduce the distance between the left and right wheels and prevent them from falling off the pole surface.In other words, the pole diameter As it becomes smaller, the wheels (Z7a) (Z7b)
) (28a) (28b) and rice respectively move inward.

Next, in the polishing mechanism section (A), Boo January 11 (1
The pole surface is polished by driving two polishing units consisting of a polishing belt (2) and a polishing belt (2). That is, when the motor αD is driven, each polishing belt (1) runs, and at the same time, the gear (6) revolves while rotating due to the free movement mechanism consisting of the gear (6) and the internal gear (3). Both polishing bells) (11 (11 polishes the entire circumference of the pole (P).

Actually, the above-mentioned polishing process is performed in the descending stroke after the polishing mechanism section (A) is moved to the tip end of the pole by the moving mechanism section CB). In that case, operate the four cylinders with air to pull the support frame (81k) supporting the boot 11 (11) toward the gear (7) located in the middle, and remove the abrasive belt (2). When polishing is to be performed next, the cylinder (c) is operated in the opposite direction to press the polishing belt (21) against the pole surface, and then the air is exhausted and the spring 02
1) to make elastic pressure contact.

However, what about the taper pole diameter? There is peace of mind in being able to vary the lifting and lowering speed of the 171I polishing mechanism (A).

That is, in the case of partial polishing, the movement is stopped and the polishing is performed, but in the case of the whole polishing, it is necessary to polish the small diameter portions quickly and the thick diameter portions while moving slowly. In the above configuration, the rack (60) and the pinion (611) are attached to the levers (c) and (b) that expand and contract in response to changes in the taper diameter.
The rotation of the pinion is detected by a variable resistor (62), and this detection signal is used to control the motor (
47) is controlled.

A tapered pole is thick at the base and becomes thinner at the tip, and the vertical part curves to become a horizontal part, but since the weight box 63 is suspended vertically from the moving shrine, it can be used as a pole with wheels. The clamping force remains unchanged.

When passing through the curved part of the pole without polishing (upward movement), cylinder Q! 5 to remove the polishing belt (2).
) should be kept away from the pole surface. When moving while polishing, remove the polishing mechanism section (A) and the sm rock structure section C.
B) is adapted to accommodate its curvature, as shown in FIG.

In other words, the polishing mechanism part (A) and the moving mechanism part CB) are attached to springs (418) above and below a hinge on the weight box side (connected by 4G, and the opposite side is a long bolt shaft +41b) so that they can be freely separated. Since it is a joint, when moving around a curved part, the swivel joint is opened using the hinge (4G) as a fulcrum, allowing smooth movement.From the horizontal part of the pole to the vertical part of the curved part When this happens, the guide plate qυ restores the original connection state.

By using the above-mentioned automatic pole polishing device, when painting poles such as lighting poles and traffic light poles, there is no need to build scaffolding for the polishing work or install a heavy-duty machine as a pre-treatment. However, it can greatly contribute to labor saving.

In addition, when the diameter of the pole is constant and only the vertical part is targeted, the above-mentioned wheels (27a) (27b) are used.

There is no need for a mechanism section that displaces (28a), (28b), and (29) following changes in the pole diameter, and a mechanism section that allows the polishing mechanism section and the moving mechanism section to be separated and separated.

As described above, according to the present invention, the pole f that is erected includes a polishing mechanism section for polishing, and a moving mechanism section that moves along the pole with the pole f. The mechanical part has two pairs of endless running abrasive belts facing each other with a pole in between, making it a planetary cycle! The J mechanism is configured to rotate the pole while driving, fL, A.
Note H: The JJ mechanism unit includes a plurality of wheels that clamp the pole at the central corner of the pole, a lever mechanism that interconnects these wheels, and a lever mechanism that presses the wheels against the pole surface. The pole itself consists of a weight suspended from a lever mechanism for polishing, and a wheel drive motor mounted on the lever mechanism, which ensures automatic polishing over the entire circumference and length of the pole. @Ken M device is obtained.
