Abstract
Description
Technical field
The utility model relates to a kind of utensil of ascending a height, and especially relates to a kind of companion ladder.
Background technology
The present utensil of ascending a height roughly has ladder and electric up-down platform, the people stands in operation inconvenience on the ladder, the electric up-down platform has lifting table, motor and the transmission device of the fixing towering track of erectting, vertical slip in orbit, open motor, lifting table is at the fixed position vertical lift, the utensil of ascending a height of so electronic, dual-use manual also do not occur at present, promptly convenient outdoor ascend operation also is convenient to move.
The utility model content
Technical problem to be solved in the utility model provides a kind of companion ladder, but this companion ladder electric-hand driven two-purpose, and promptly convenient outdoor ascend operation also is convenient to move.
Solve the problems of the technologies described above, the technical solution of the utility model is: a kind of companion ladder, comprise support body, lifting table, the below of described lifting table is provided with electric lifting mechanism and hand lifting mechanism, support body comprises four groups of upright runway tooth bars that are positioned at around the lifting table, electric lifting mechanism comprises motor, the drive link of two levels, chain wheel driving mechanism, four lifter wheels of advancing, advance for four and protect wheel and worm-and-wheel gear, each lifter wheel and advancing of advancing protects wheel and fuses and match with the runway tooth bar, the worm screw of worm-and-wheel gear lays respectively at the two ends of two drive links, four worm gears then respectively with four coaxial being fixed together of the lifter wheel of advancing, two drive links link to each other with realizing the synchronous attaching parts of drive link that is synchronized with the movement.
Described hand lifting mechanism comprises the hand cranking handle of the hand chain-wheel mechanism that connects two drive links and lifting table below.
Described lifting table is a rectangular plate shape, and described four groups of upright runway tooth bars are positioned at four jiaos of places of lifting table.
Described each runway tooth bar is that more piece makes up from beginning to end.
A kind of companion ladder of the utility model adopts such structure, companion ladder can move arbitrarily, when being arranged, electricity can drive fast about the elevator chamber by reducing motor, in the time of no electricity or sudden power, the mountaineer can pass through hand-operated mechanism, make about the elevator chamber, can not hang in midair, in the open air away from the place of power supply also ascend operation very easily because of sudden power makes elevator chamber.
Description of drawings
Below in conjunction with accompanying drawing a kind of companion ladder of the utility model is done explanation in further detail;
Fig. 1 is the structural representation of a kind of companion ladder of the utility model;
In Fig. 1,1, the runway tooth bar; 2, the lifter wheel of advancing; 3, advance and protect wheel; 4, worm gear; 5, drive link; 6, the synchronous attaching parts of drive link; 7, hand lifting mechanism; 8, chain wheel driving mechanism; 9, lifting table; 10, motor; 11, hand cranking handle.
The specific embodiment
A kind of companion ladder, comprise support body, lifting table 9, electric lifting mechanism and hand lifting mechanism, lifting table 9 is a rectangular plate shape, and electric lifting mechanism and hand lifting mechanism are positioned at the below of lifting table 9, and support body comprises four groups of upright runway tooth bars 1 that are positioned at 9 four jiaos of places of lifting table.Electric lifting mechanism comprises that the drive link 5, chain wheel driving mechanism 8 of motor 10, two levels, four lifter wheels 2 of advancing, four are advanced and protects wheel 3 and worm-and-wheel gear, each lifter wheel 2 and advancing of advancing protects wheel 3 and fuses and match with runway tooth bar 1, the worm screw of worm-and-wheel gear lays respectively at the two ends of two drive links 5, the angle of spiral of worm screw is less than the equivalent friction angle of active flank, 4 on four worm gears respectively with four lifter wheel 2 coaxial being fixed together of advancing, two drive links 5 link to each other by the synchronous attaching parts 6 of drive link and realize being synchronized with the movement.Hand lifting mechanism 7 has increased hand chain-wheel mechanism and the hand cranking handle 11 that connects two drive links 5.
The user, just can be performed as follows after winding installs the companion ladder that satisfies work requirements by the needs of operating altitude:
A, under the situation that electricity is being arranged, connect motor power, driving chain-wheel mechanism when motor is just changeing just changes, worm screw just changes, worm gear just changes, the lifter wheel of advancing upwards rotates, lifting table rises; During the motor counter-rotating, lifting table descends.
B, do not having under the situation of power supply, the forward rotation hand cranking handle, driving hand chain-wheel mechanism just changes, and worm screw just changes, and worm gear just changes, and the lifter wheel of advancing upwards rotates, and lifting table rises; The backward rotation hand cranking handle, elevator chamber descends.
C, when sudden power, no matter where lifting table rests on, can be by rotating hand cranking handle, about the operation elevator chamber.
D, owing to adopted worm and worm gear, the angle of spiral of design worm screw is less than the equivalent friction angle of active flank, worm drive just has self-locking performance, as long as motor outage or hand stopping, lifting table just is fixed on a certain height, the user just can highly carry out work at this, starter motor or rotation hand cranking handle after work is finished, and the user just can rise or descend by the operate lifting platform.
