Description

System for lifting and moving an object             

Technical Field
The present invention relates to an apparatus for lifting and moving objects from one position to another.
Background
Many devices are known for lifting and moving objects from one location to another. However, the devices are inconvenient to use and expensive to manufacture.
Detailed description of the invention
The main features and advantages of the present invention reside in the action of weight.
1. The upward motion may be at an air pressure of 4 pounds per square inch (4 PSI) or 30 Pascals (30 Pa).
2. The sealing principle of weight (piston) is to use air friction as it moves through a small crack. This principle makes it possible to generate air pressure under the piston with very little air.
3. Another advantage of the above principle is that the small amount of air leakage that occurs causes the piston to stay centered in the tube and eliminates the wear effect between the weight and the inside of the post.
4. The use of this leakage system, along with ensuring guiding and sealing action, eliminates the need to pressurize the piston top and the use of an air bleed valve. Such a system only needs to reduce or close the air intake, allowing it to be simply lowered by additional gravity to raise the object.
5. It is impossible to abuse or destroy the device due to the fact that only 99% of the weight of the weight can be used to lift the object. The friction of the mechanical elements is the reason for the 1% weight loss.
6. Using the support pillar as the compression chamber allows 360 degrees of continuous movement.
7. The proximity of the two pulleys of the carriage supporting the object attachment member through the cable is due to the local angle provided to the cable between each pulley and the object attachment member, which causes the operator to try to raise the object too high. Induce braking effects.
8. The weights can be of variable weight and can be emptied quickly due to a vessel with a trap installed on the bottom.
a) The container is open at the top. The tank installed on top of the device can be filled with liquid or granular material using quiet moments. The trap at the bottom is used as a weight container as needed.
b) The method of bringing granule material or liquid can be achieved in a continuous motion using a 1/4 HP (or 190 watt) compact conveyor system with jars.
c) The operation of the weight may be by means of liquid (water, oil, mercury) or granule material (sand, steel balls, polymer balls).
d) If mercury is chosen, everything should be done in a closed circuit to prevent the possibility of environmental pollution. It should be noted that mercury, although expensive, has the advantage of being very compact.
The present invention relates to a system and apparatus for lifting and moving an object from one position to another, the system and apparatus comprising:
a) a partially hollow column having a generally vertical axis;
b) a weight disposed within and forming a pillar chamber thereunder, wherein the pillar chamber can be filled with a pressure fluid;
c) a weight displacement system for displacing the weight longitudinally and upwardly relative to the column, the weight displacement system regulating pressure in the column chamber to selectively position the weight along the column;
d) a transverse arm rotatably connected to said pillar to rotate about said vertical axis, said transverse arm having a longitudinal end of a proximal end positioned proximate said post and a longitudinal end of a distal end located away from said post;
e) a cable having one end attached to the weight and the other end attached to the distal end of the cross arm;
f) a carriage connected to said cable and mounted to said cross arm; And
g) an object attachment member connected to said cable for attaching an object,
An object is raised through the cable upon downward displacement of the weight with respect to the column under gravity, and descends upon upward displacement of the weight with respect to the column under pressurized fluid in the column chamber.

Example
The device is a total of 12 feet (or 4 m) in the transverse direction, fixed to the top of a pillar 2 8 to 12 feet (or 2.5 to 4 meters) in height and 8 inches (or 20 cm) in diameter The rail 38 is provided.
The rail 38 is secured to the column 2 using an arm connection system or a rotary joint 40, which is a continuous 360 degree unrestricted and unobstructed around the column about the axis of the column and beyond. Enable exercise
A hole is provided in the rotary joint 40 to allow free movement of the cable 29 while the weight 5 is raised or lowered. As shown in FIGS. 2, 10 and 11, the rotary joint 40 is located in the center of the lid 35 attached to the top of the pillar 2. The cable 29 passes through the guide 24 around the pulley 41 which is rotated around the horizontal axis 20. The bearing 42 is arrange | positioned between the support cylinder 21 and the guide part 24 fixed to the rail 38 by the bolt 23 or a well-known means.
Holes in the rotary joint 40 allow free movement of the cable 29 during further ascension or descending.
The rail 38 is supported by two 1 inch (or 2.5 cm) square elongated supports or braces 26 and vertical braces 25, which brace 26 is one longitudinal end rotation fixed by rails. With opposite lengthwise ends bolted to the block 27, the vertical brace 25 is connected to the rotating block 27 via the same bolt 28.
The rotary block 27 can move laterally in the tangential direction on the outside of the pillar 2 by the aid of two bearings 12.
The small carriage 50 provided in the rail 38 and provided with the pulley 11, the wheel 12, the bearing 14, and the screw 16 mounted to the shaft 13 is provided as a whole. A wheel 12 on the coaxial line is used to allow the load to move freely along the rail.
The end of the rail 38 is covered with a cover 19 to close the opening and keep the end of the cable 29 in place.
The lower side of the pillar 2 is welded to the triangular base 1 which is fixed with anchors 3-34 at the bottom at each corner and filled with epoxy.
The sealing member is preferably made of two plastic rings 6 provided on the upper side and the lower side of the weight 5 to suppress friction between the metal parts. They are adjusted to leak air or other gases at predetermined volumes according to requirements.
A weight displacement system, such as a valve 33 installed underneath the column, allows control of the air intake used to raise the weight.
Description of the device
One piece of rubber 7 fastened to the lower side of the weight bolt 8 eliminates the impact at the time of lowering.
Two black high density steel bands 17 on the inner side of the rail 38 smooth the movement of the carriage 50.
A 5/8 inch (or 1.5 cm) bearing 15 ensures alignment of the carriage at the opening of the rail 38.
The relatively small mass of the object attachment member, such as the attachment block 30, keeps the cable 29 in tension, thereby preventing the cable from deviating from the two pulleys 11 in the same plane.
Mechanical function of the device
This device has three distinct functions.
a) offset by weight the weight of the object to be lifted;
b) allows the driver to raise or lower the object easily; And
c) Move an object with a radius of 2 to 12 feet (or 60 cm to 4 m) at an angle of 360 degrees.
Device operating procedure
The device is a lifting arm that can easily handle any solid object that can be grabbed by suction disks, magnets, hooks or other holding systems.
The driver can handle objects within 24 feet (or 8 meters) in diameter and can control the rise and fall by wireless or wired remote controls.
The stand on which the remote control is installed may also be used as a handle for the driver at the base of the holding system.
The holding system can have any shape applicable.
As an example, when using a sheet coated with melamine, the driver injects air under the weight. As a result, the holding system (in this case the suction disk) is lowered to the top of the seat. Once the seat is properly caught, the driver bleeds out, further descends and subsequently lifts the seat. The driver then moves the seat to the required place and injects air again to lower the seat. Finally, the driver releases the seat and prepares to perform another action.
The device is designed to handle small loads of 50 to 150 lbs (or 2 to 70 Kg).
It is preferably provided with a piston moving up and down under pressure generated by the fluid of the liquid, gas or granule, preferably the fluid is air, inert gas, synthetic oil, natural oil, mercury, water, or sand and Vertical pillars are provided that are within elements such as gravity;
The piston is provided which is rigidly supported by a cable on a pallet moving inside or above the side arm and which keeps the holding system at the same distance from the pallet no matter where the piston is located along the arm.
