Abstract

Machine for easily lifting and transferring ferrous covers for sewer, water, gas, electricity, telephone, ... network registers, whose closing system is its own weight, characterized by the use of neodymium magnets. (Machine-translation by Google Translate, not legally binding)

Description

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

Technical sector

The invention is part of the installation and maintenance of networks of

sewer, water, gas, electricity, telephone, etc.

State of the art

Currently the methods used are usually or a simple hook,

with which a considerable physical effort is made, or through

hydraulic trucks or not, whose fixing means to the covers are

(Chains or thymes with hooks) which is very slow and laborious.

Explanation

Machine for easily lifting and moving iron covers of records

sewage networks, water, gas, electricity, telephony etc, using

neodymium magnets. The machine is a first-gen lever whose

resistance arm, supports the grip head where they go

housed the magnets, the point of support are the wheels, and the arm of

power, near whose end is the handle. Inside the head

of grip are mounted 10 neodymium magnets 30x30x15mm with this

75Kg are lifted, a larger head can be mounted to accommodate magnets

40x40x20mm to lift 150Kg these weights refer to caps

whose diameter does not exceed 800mm, it can also lift

any cover that has other figures provided that from one side to the

center of gravity does not exceed 400mm, the head is tight what

allows its use under water (floods) ..ect. This

invention comes to solve the problems explained in the state

On the one hand, the physical effort is drastically reduced (50 or

60%) and on the other also the down operations are reduced.

The way of use is as follows: the protective housing of the

grip head and this rests on the approximate center of the lid is

press down on the handle and the lid lifts easily

being able to move it on the wheels. To release the lid head,

Press the handle up and release easily, thanks to its design.

To place the cover in its housing, the process is repeated.

The whole machine is made of stainless steel, except the wheels, (5)

the magnets (18) and the protective housing (10) of the grip head (9)

DESCRIPTION OF THE DRAWINGS

5 Figure No. 1. Represents the lever that forms the machine

The figure shown shows two tubes (3) and (7) welded together at an angle of 120 ° with an inner reinforcement (6), near the upper end of the tube (3) is the handle (1) also welded and with a reinforcement (2)

Inside the tube (3), the wheel support (4) is also welded to this tube (3) with a socket for its coupling and in such a way that it allows the wheel shaft (12) to pass through it. , the power arm extends from the handle (1) to the support of the wheels (4), the tube (7) at its end is welded the support of the grip head (8) this has its

Once the grip head (9) is welded, the resistance arm extends from the wheel support (4) to the grip head, finally the protective housing of the grip head (10) is shown.

Figure N ° 2 Exploded view of the wheels (5) and its support (4)

20 The wheels are mounted as follows: inside the wheel support (4) and at their ends two pieces (15) are mounted that fit perfectly and are drilled to allow the wheel axle to pass

(12) once the shaft (12) is mounted, each side is mounted on a

25 washer (13) having a diameter greater than the width of the support (4) then a round tube (14) having the inner diameter is mounted a few tenths greater than the axle of the wheels (12) the outer diameter is a few tenths smaller that the bore of the wheels (5) and its length is a few tenths greater than the width of the wheels (5) then another washer (13) is mounted and by

Last 30 the nut (11) is mounted, which is self braking

Figure N ° 3 Exploded view of the grip head (9)

It is formed by an omega profile (16) which forms four of the six

35 sides of the housing of the magnets, another side is formed by the bottom cover (21) which is sealed and riveted by solid stainless steel rivets and with a flat head forms the fifth side and with the cover (19) and the cover support ( 20) that are riveted together and sealed to the omega profile (16) and attached to it by means of the screw (22) to the nut (17) riveted to the

40 the upper tab of the omega profile (16) conforms to the sixth side
