ES2557412A1 - Machine to easily lift and move iron covers of underground water, gas, electricity, telephony sewer networks, etc. Using neodymium magnets (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Lift and move iron covers of underground network registers. The invention comes to solve the problem that means lifting these covers simply with a hook and therefore to bear all the weight and physical effort that this entails, as the machine is a first-class lever whose resistance arm (7) supports at its end an articulated grip head (9) where the magnets (17) are housed, the point of support are the wheels (5), and the power arm (3), at the end of which the handle (1) eliminates 50 or 60% of the effort in addition to the ease of hooking the machine to the lids by means of the magnets that translates into: supporting the gripping head on top of the lid to be lifted and then with the wheels (5) for the transfer of it.

DESCRIPTION

Machine to easily lift and transfer ferric covers of registers of underground networks of sewage systems of water, gas, electricity, telephone etc ... using neodymium magnets.

Technology Sector

The invention is part of the installation and maintenance of underground sewerage, water, gas, electricity, telephone networks etc ...

State of the art

Currently the methods used to lift these covers are usually either a simple hook, which makes a considerable physical effort, or by means of hydraulic or mechanical trucks, whose fixing means to the covers are (chains or screws with hooks ) which is very slow and laborious. I am not aware that there is any machine that lifts covers that are opened by hinges. These covers are opened by unlocking the lid if it has any type of closure and then lifting the lid by hand or with a hook.

These covers have a weight of between 30 and 40 kg so lifting them with hooks and a single person is contraindicated by occupational health regulations.

The most important of this invention is the considerable physical effort that eliminates and prevents injuries by reducing this effort by 50% or 60%, while reducing the time of the hitch operations to be performed.

The present invention relates to a lever that eliminates much of the necessary physical effort and at the same time the problems of hooking the covers.

Since the coupling system is made of neodymium magnets that are housed in the grip head, it rests on the cover to be lifted and the coupling operation is completed. It also lifts covers of other materials provided that these covers are provided with a rail strip in its diameter of 40x400mm where you can hook the machine.

The machine is a first-gen lever formed by the union of two tubes (3) and (7) at an angle of 120 °. These tubes are joined by means of the reinforcement piece (6), the tube (3) arm of power is joined by means of a recess that has the piece (6) and is secured by means of a quick-acting pin (12). This power arm (3) at the upper end is welded with a reinforcement piece (2) which is drilled to allow the handle (1) that is secured by welding to be installed in the hole, in this way! You can mount the stirrup (11) consisting of two twisted steel cables with a loop each having the loop a slightly larger diameter than the tube that forms the way! (one). To allow mounting, at the other end of the cables, these are hooked to a "U" profile that with the cables form the stirrup (11).

The resistance arm (7) is joined to the part (6) by welding, the wheel support (4) is also welded to this part (6). In this support (4) the wheels are mounted

(5). The wheels are the fulcrum of the lever and also serve to move the covers once they are attached to the machine and suspended. On the other end of the resistance arm (7) and perpendicular to this and in its center the support (8) of the hinges (14) whose half is welded to this support (8) is welded.

The other half of the hinges (14) are welded to the grip head (9), to allow its rotation, and which houses the magnets (17) inside. In the resistance arm (7) two plates (13) are mounted one on each side of the tube that are the support of the piece (19) that has a screw (20) with its nut and that serves as the axis of rotation to this piece (19). Both the plates (13) and the locking piece (19) have a through hole so that by means of the quick-acting pin (12) it serves to block the gripping head (9). In addition to serving to release the lid once opened when acting as a stop when the machine is operating with hinged covers.

Gripping head

In the machine two gripping heads of different power can be mounted according to the weight of the lids to lift one that lifts up to 75 kg and another can lift up to 125 kg.

The machine has two possible configurations Configuration 1a

This configuration is for covers whose closing system is its own weight, the machine is configured by blocking the grip head (9) leaving it fixed. This is achieved by fixing the locking piece (19) by means of the quick-acting pin (12). The procedure for lifting the lid is reduced to supporting the grip head (9) in the approximate center of the lid to be lifted and then pushing the handle (1) down either with the hands or with the foot on the stirrup (11 ), the lid is lifted and by means of the wheels (5), it can be moved, to release the lid the head has to remain locked, to release the lid the handle (1) is pushed up, and the grip head (9) it is released, so as not to have to lift the weight of the machine, the handle (1) is tilted, resting the grip head (9), on one of its corners and then the wheel on that side on the ground, leaving the lid loose

2nd configuration

This configuration is for covers whose opening system is hinged, the machine is configured by leaving the grip head (9) in rotating mode, this is achieved by freeing the locking part (19) by removing the pin (12). The procedure for lifting the lid is as follows: the grip head (9) is supported in the center of the lid to be lifted by placing the machine so that the lid hinge is between the grip head (9) and the wheels ( 5) of the machine, after releasing or opening the closure or latch of the lid if it has it, the handle (1) is pushed down either with the hands or with the foot on the stirrup (11) and the cover will rotate on its hinge opening, if you want to release the lid of the machine in the open lid position you will have to open the lid until it stops butt with the support of the locking piece (19) releasing, to release the lid in position With the lid closed, the grip head (9) must be fixed or locked, by means of the locking piece (19) and the pin (12), to release the lid in this position the handle (1) is pushed up and the head of

grip (9) is released, so as not to have to lift the weight of the machine the way tilts! resting the grip head (9) on one of its corners and then the wheel on that side on the ground leaving the machine loose.

Description of the drawings

Figure 1

It represents the machine in its entirety. The figure shown shows a tube (3) with a reinforcement piece (2) welded at its upper end which in turn is pierced by a hole that allows a round tube (1) to pass, which is welded to this part by the handle ( 1), on the way! You can mount the two steel cables that together with the sheet attached to its other end form the stirrup (11). Near the lower end of the tube (3), the quick-acting pin (12) used to secure the tube (3) to the reinforcement (6) is attached to it by means of a stainless steel cable. To this reinforcement (6) are welded both the support of the wheels (4) and the tube (7) to this tube are welded two pieces (13) one on each side of the tube that serve as support to the blocking piece (19 ). This locking piece is secured in said support (13) by its rear part by means of a screw (20) with nut and washers that acts as a rotating shaft, in the front part both the two supports (13) and the locking piece (19) are traversed by a drill where the grip head is locked by means of a quick-acting pin, this quick-acting pin (12) is attached to the tube (7) by a thin steel cable, to the tube (7) also the grip head support (8) is welded, to this support (8) the hinges (14) are welded which in turn support the grip head (9) where the magnets are housed, finally the protective housing is represented of the grip head (10).

It represents the grip head (9) in its fixed configuration by means of the locking piece (19) and by means of the quick-acting pin (12).

Figure 3

Represents the grip head in its rotary configuration with the locking piece (19) unblocked.

Figure N ° 4

It represents the exploded view of the grip head (9), it is formed by an omega profile (16) closed at its longitudinal ends with the same configuration as the rest of the profile. This forms 5 of the sides of the housing of the magnets (17), the sixth side is formed by a sheet (18) that sealed and riveted forms the housing of the magnets or grip head (9).
