Abstract
A device for raising and lowering an equipment housing (1)
into a pit includes a set of ramps (6,7) preferably built
into the sides of a pre-cast pit housing. The equipment
housing (1) is fitted with wheels (4,5) to engage the ramps (6,7).
A winch mounting (8) is provided near the top end of the
ramps, and a winch (9) is removably mounted in mounting (8),
the winch being attached to housing (1) by cable (10), whereby
the housing can be safety raised and lowered.
Description
The following statement is a full description of
this invention, including the best method of
performing it known to us:
This invention relates to an arrangement for raising and
lowering heavy articles and will be described with
reference to installations for electronic equipment in
below ground pits.
At present heavy equipment housings are installed in and
removed from pits by the use of a crane. This is a labour
intensive process, requiring a technician to provide access
to the pit, which is usually locked by the telecom carrier,
and a crane driver. Time is also wasted in co-ordinating
the arrival of the crane at the installation.
A first embodiment of the invention includes ramp means
permanently or temporarily installed in the pit and
arranged so the equipment housing may be raised or lowered
along the ramp means.
In one embodiment, the equipment housing interacts with a
wheeled or rolling mechanism affixed to the housing or the
ramp means.
In a second embodiment the housing slides up or down the
ramp.
In a preferred embodiment the ramp means includes a pair of
substantially parallel inclined ramps attached to opposite
side walls of the pit.
In a further embodiment, a winch mounting is included in
the end wall of the pit at the top end of the ramp means.
The invention will be described with reference to the
accompanying drawings in which:
- Figure 1
- is a side view illustrating an embodiment of the invention;
- Figure 2
- is an "X-ray" perspective showing the equipment housing in the lowered position in the pit.
- Figure 3
- shows an alternative embodiment of the invention.
- Figure 4
- shows a further embodiment of the invention.
Figure 1 shows an arrangement for facilitating access to
equipment contained in housing 1 which is installed in a
pit 2. The housing is shown in the raised position.
The equipment housing 1 is fitted with a first pair of
wheels, 5, at the front end, and a second pair of wheels at
the rear end. Wheel 5 rests on a plateau 11 at the top of
ramp 7, and wheel and rests on plateau 12 at the top of
ramp 6. A backstop on each plateau prevents the housing
rolling off one side of the plateau.
The housing 1 is held on the plateaus by cable 10 attached
to winch 9 which is mounted in or adjacent to the pit 2 at
mounting points.
In this raised position the housing may be opened to enable
a technician to access the equipment inside the housing.
As better shown in Figure 2, the pair of wheels 4 co-operate
with a pair of ramps 6 attached to opposite side
walls of the pit 1, and similarly the pair of wheels 5 co-operate
with a corresponding pair of ramps 7.
In Figure 2, housing 1 is shown in the lowered position. In
this position, the winch 9 and cable 10 can be detached and
a lid placed over the pit and optionally locked in
position.
Figures 1 & 2 illustrate how the housing 1 can be raised
and lowered in the pit by the use of the ramps 6 & 7.
Preferably a winch 9 is used to raise and lower the housing
1.
The housing 1 may be connected to one or more communication
cables, 3, having sufficient flexibility to permit the
raising and lowering of the housing 1.
In a preferred embodiment, the pit is made of precast
material, such as concrete or fibreglass, and the ramps 6 &
7 are moulded into the side walls. Optionally, metal strips
may line the ramps and plateaus to provide a stronger
contact surface. Alternatively, the ramps 6 & 7 may be
portable and inserted into the pit when it is necessary to
raise the housing 1. Instead of wheels, angled skids
parallel to the angle of the ramps may be affixed to the
sides of the housing 1. In a development of this
embodiment, the ramp may be substituted by an inclined
wheeled or roller arrangement.
Figure 3 shows sets of wheels or rollers 36, 37 fixed in an
inclined plane and corresponding ramps 34, 35 affixed to
the equipment care.
The lower ends of the ramps include horizontal regions 38,
39 to provide stability when the housing is raised. The
upper ends of the ramps are tapered (310, 311) to ensure
smooth engagement with the wheels or rollers.
This configuration may be suitable where the inclined sets
of wheels are carried by the technician, as this eliminates
the need to affix wheels to all the housings. The portable
wheels also include abutment means (not shown) to retain
the sets of wheels in place while under load by preventing
longitudinal or transverse movement.
Figure 4 shows an embodiment using only one pair of ramps
47 co-operating with a single pair of wheels or skids 45
affixed to the housing. An additional ledge 49 is provided
to support the housing in the raised position.
