Said vertical post comprising a piston connected to a carriage (10-16) slidably mounted on said lifting arm, such that operation of said piston can lower and raise said carriage.

Description

"SYSTEM FOR LIFTING AND MOVING AN OBJECT".

Technical field

The invention relates to apparatus for lifting objects and moving them from one location to another.

Technical background

Many devices for lifting and moving objects from one location to another are known. However they are cumbersome to use and expensive to manufacture.

Summary of the invention

The main features and advantages of this invention lie in the "weight operation".

1. Its upward movement is made possible with low air pressure of four pounds per square inch (4PSI) or thirty pascals (30 Pa).

2. The weight sealing principle (piston) is to use air friction when it is moved through a small gap. This principle allows the creation of air pressure below the piston using very little air.

3. Another advantage with this principle is the fact that the small air leak created makes the piston centered in the pipe and eliminates the effect of wear between the pressure and the inside of the post.

4. Along with ensuring guidance and sealing, the use of this leakage system eliminates the need to pressurize the piston top or use an air exhaust valve. This system only requires the reduction or closing of the air intake to allow weight to be lowered simply by gravity thereby elevating the object.

5. It is impossible to abuse or break this equipment due to the fact that it can only lift an object using 99% of the weight mass. Mechanical element friction is the reason for the 1% loss.

6. Using the support post as the compression chamber allows continuous 360 degree movement.

7. The proximity of the two trolley pulleys supporting the object-to-cable linkage produces an event-breaking effect that the operator attempts to climb very high due to the local angle provided to the cable between each pulley and the object-binding member.

8. The weight can be of variable mass and is a container equipped with a bottom drain that allows rapid emptying.

a) This container is opened at the top. A tank installed on top of the equipment can be filled with granular material or liquid using quiet moments. A drain on its bottom is used to fill the required weight container.

b) The method of bringing granular or liquid material can be achieved using a small 1/4 HP (or 190 watts) conveyor system with mugs in one continuous motion.

c) Weight management can be made possible using liquids (water, oil, mercury) or granular material (sand, steel balls, polymeric balls).

d) If mercury is chosen, everything must be done in a closed circuit to avoid possible contamination of the environment. It should be noted that mercury has the advantage of being very compact though extremely expensive.

Description of a preferred setting

The apparatus consists of a 12 foot (or 4 meter) long track (38), generally transverse attached to the top of a 8 to 12 foot (or 2.5 to 4 meter) pole height, 8 inches (or 20 cm) in diameter (2).

The rail (38) is fixed to the post (2) by means of a swivel joint (40), or arm connection system, which allows its unlimited and unobstructed continuous movement around the post axis by 360 ° or more.

A hole is provided in a rotary joint (40) to allow free movement of a cable (29) while the pressure (5) is raised or lowered. As shown in figures 2, 10, 11 and 12, the rotary joint (40) is located in the center of a cover (35) connected to the top of the side (2). The cable (29) passes through a guide (24) and around a pulley (41) that rotates around a horizontal axis (20). A bearing (42) is disposed between the guide (24) and the support cylinder (21) which is fixed to the grid (38) by screws (23) or other known means. A spacer (22) is disposed between the cover (35) and the support (21).

A hole in the rotary joint (40) allows free movement of a cable (29) while the weight is raised or lowered. The rail (38) is supported by two elongated ribs or 1 inch (or 2.5 cm) square arms (26) ) has a longitudinal end fixed thereto and the opposite longitudinal end is screwed to a blocking wheel (27) and a vertical arm (25) also connected to the rotating block (27) through the same screw (28).

The rotating block (27) can move laterally in a tangential direction externally to the post (2) with the help of two bearings (12 ').

A small trolley (50) including pulleys (11) mounted on its axles (13), wheels (12), bearing (14) and bolt (16) installed inside the rail (38) allows the load to move freely along the rail using the two generally coaxial wheels (12).

The end of the rail (38) is capped (19) to close the opening and hold the cable end (29) in place. The bottom of the pole (2) is welded to an anchored triangular base (1) (3-34) to the floor at every angle and filled with epoxy.

A sealing member is preferably made of plastic rings (6) installed at the top and bottom of the weight (5) preventing friction between metal parts. They are adjusted to let air or other gases leak at a preset volume, depending on the request.

A weight shift system such as a valve (33) installed at the bottom of the pole allows control of the air intake used to lift the weight.

Equipment description

A rubber piece (7) bolted (8) to the bottom of the weight eliminates impacts when lowering.

Two black high-density steel straps (17) on the rail (38) smoothen the movement of the trolley (5). A 5/8 inch (or 1.5 cm) bearing (15) ensures trolley alignment action on the opening of the rail (38).

The relatively small mass of an object coupling member such as the coupling block (30) prevents cables (29) from falling out of the two generally planar pulleys (11) keeping them in tension.

Mechanical Function of Equipment

This handset has three distinct functions:

(a) cancel the mass of an object to be lifted by a weight;

(b) allow the operator to easily lift and lower an object; and

c) Move an object with a radius of two to 12 feet (or 60cm to 4 m) by 3 60 degrees.

Equipment Operating Procedures

This equipment is a lifting arm allowing easy handling of any solid object that can be held by a suction cup, a magnet, a hook or any other restraint system.

The operator can handle the object within a 24 foot (or 8 meter) diameter and controls lifting and lowering by either a wireless or connected remote control.

The base on which the remote control is installed is also used as a handle for the operator at the base of the retention system.

The restraint system may be of any applicable form.

Using a melanin coated sheet as an example, the operator inserts air under the weight. As a result, the retention system (in this case the suction cup) lowers over the top of the sheet. Once the leaf is properly secured, it releases air and the weight goes down, thus raising the leaf. The operator can then move the sheet where required and reinsert air to lower it. Finally, he releases the cork and is ready for another maneuver.

This equipment is designed to handle small loads ranging from 50 to 150 pounds (or 20 to 70 kg). The vertical pole is equipped inside with a piston moving up and down, preferably under pressure created by a fluid, either liquid, or granular gas and preferably within such element as inert gases, synthetic or natural oil, mercury, water or sand, and under gravity, respectively.

The aforementioned piston being firmly secured by a cable to the trolley by moving in or over the lateral arm and forcing the retention system to remain at the same distance from the trolley regardless of its long arm position.
