Description
Technical field
The present invention relates to technical field of buildings, more specifically to a kind of safety-type lifting device of construction.
Background technique
Construction material is frequently necessary to use the mechanical equipment that auxiliary is carried in the handling process, and whether mechanical equipment safely may be used
It leans on, is related to the security of the lives and property of construction party, especially hoists from lower and transport building materials, it must not due to large labor intensity
Without using hoistable platform, whether hoistable platform is reliable particularly important.Building hoist is strong etc. because of its energy conservation, safety, hoisting power
Feature becomes the leading products in current elevator market.Elevator is lifting device common in the fields such as building, can be real
Existing material or the loading of operator, elevator are all mounted to complete descending operation on standard knot, existing elevator knot
Structure is simple, and the descending operation of an elevator is realized on a standard knot, and not only reliability and stability cannot be guaranteed, but also
Influence efficiency.And elevator is mainly by traction machine, guide rail, counterweight, safety device, signal manipulation system, loading space and compartment door
Deng composition.Existing building hoist loading space unreasonable structure, it is big that there are occupied spaces, no safety device.There are also
The lifting of construction material is carried out using other lifting devices during construction, but existing many lifting devices have peace
The problem of full performance difference.
As China Patent No. is that CN201520348765.4 discloses a kind of lifting device for building, including bottom plate, top plate,
Weight body, hoisting machine, hanging basket, running gear, support device and Machine Room, the plate upper surface middle part are equipped with counterweight
Body, weight body upper end are equipped with top plate, and weight body two sides are respectively provided with a hoisting machine, are connected by wirerope with hanging basket, institute
The bottom plate lower part stated is equipped with instrument room, and the inside of instrument room is equipped with required instrument, and the lower part of instrument room is equipped with support device,
The two sides of support device are equipped with running gear, the utility model has the following beneficial effects: structure is simple, easy to use, elevator is torn open
Dress and transport are all very convenient, low in cost, thus are not only suitable for outdoor and are also applied for interior；Finishing replaces herringbone indoors
Ladder, building construction or finishing particularly suitable for small towns rural area.But the invention is not provided with more during material is gone up and down
The problem of more security protections is arranged, and still remains security performance.
For another example China Patent No. is that CN201721514477.7 discloses a kind of elevator for building, including base, machine
The inside of seat is equipped with cabinet, and the left and right sides inner wall of base offers loose slot, between the inside top and bottom of loose slot
It is fixedly connected with slide bar, the left and right of cabinet is fixedly connected to movable block, and movable block is socketed on slide bar, is socketed on slide bar strong
Power spring and lower brute spring, the top of upper brute spring are fixedly connected on the top of slide bar.The invention passes through setting base, machine
The horizontal lifting pedestal of case, loose slot, slide bar, movable block, upper brute spring, lower brute spring cooperates, and effectively the external world shakes
Power is slackened, and reduces influence of the vibration force to equipment inner body, solves existing building lift by the external world
Vibration cannot effectively buffer reduction equipment part service life the problem of, but the elevator of the invention it is not smart enough with just
It is prompt.
For another example the patent of Patent No. JP2012268582 has the electric system of the building of elevator.The system has
Electrical storage device, elevator, guidance device, control device.Electrical storage device can to the electric power for making the electrical equipment of building work into
Row electric power storage.Elevator is gone up and down by from the electric power for the above-mentioned electrical storage device that above-mentioned building is arranged in.Guidance device carries out
Guide relevant to the operating of above-mentioned elevator.Control device controls above-mentioned guidance device, guides related to above-mentioned electrical storage device
Information.Although the invention has been realized in intelligent control, the installation of the device is complicated, and convenience is not high, and does not have
Further improvement is made in conjunction with lifting device.
To sum up, there are also very for the practical problem urgently handled in the lifting device design field of building, practical application
