Description

A kind of telescopic arm structure on aerial work platform
Technical field
The utility model is related to aerial work platform technical field, more particularly to stretching on a kind of aerial work platform Contracting arm configuration.
Background technology
Aerial work platform is common working at height auxiliary tool, will be made using hydraulic system or other driving devices Industry platform is raised to high-altitude, is extended by telescopic rod and realizes transverse shifting, and telescopic rod is stretched longer, and operating radius is also bigger, but Meanwhile telescopic rod is stretched longer, can show that bottom base is also more unstable by lever principle, that stretches is long, easily loses Balance causes the extreme direction before telescopic rod to overturn, therefore as the research direction of the industry technical staff such issues that solution.
Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of, provides the telescopic arm structure on a kind of aerial work platform, packet Include lifting column, lifting column is equipped with mounting bracket, and first sleeve is connected by first support on mounting bracket, by the in first sleeve Two stents connect the second casing, and first sleeve and the second casing are arranged in parallel, and counterweight cylinder, counterweight cylinder are equipped in first sleeve Including the first thread segment and the first smooth section, the first thread segment diameter is more than the first smooth section, and cross bar is equipped in the second casing, horizontal Bar includes the second thread segment and the second smooth section, and the second thread segment diameter is more than the second smooth section, first sleeve and the second casing Outer wall on be equipped with opening, between first sleeve and the second casing be equipped with worm gear, worm gear pass through shaft connect decelerating motor, snail Wheel is engaged by opening with the first thread segment and the second thread segment respectively, and worm gear is by the engagement with the first thread segment and with bicircular Column is sequentially connected, and worm gear is sequentially connected by the engagement with the second thread segment and cross bar, under the driving of decelerating motor, cross bar and Counterweight cylinder moves round about respectively, achievees the effect that balance.
Preferably, first thread segment is located at the right part of counterweight cylinder, and the second thread segment is located at the left part of cross bar.
Preferably, the right end of the cross bar passes through cantilever connection operation hanging basket.
Preferably, both ends are equipped with limited block on second internal surface of sleeve pipe, are skidded off out of casing to avoid cross bar.This reality It is with Novel work principle:Under the driving effect of decelerating motor, worm gear and the engagement of the first thread segment realize worm gear and with bicircular Column is sequentially connected, and worm gear and the engagement of the second thread segment realize that worm gear and cross bar are sequentially connected, therefore can realize that cross bar forward extends out While, counterweight cylinder is stretched backward, also just achievees the purpose that balance.
The beneficial effects of the utility model are:The utility model is novel in design, simple in structure, can be when cross bar stretches By the flexible come counterpoise of counterweight cylinder, prevent from toppling over to cross bar telescopic direction.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein:
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
As shown in Figure 1, the utility model is the telescopic arm structure on a kind of aerial work platform, including lifting column 1, lifting Column 1 is equipped with mounting bracket 2, connects first sleeve 4 by first support 3 on mounting bracket 2, passes through second support 5 in first sleeve 4 The second casing 6 is connected, 4 and second casing 6 of first sleeve is arranged in parallel, and counterweight cylinder 7, counterweight cylinder 7 are equipped in first sleeve 4 Including the first thread segment 71 and the first smooth section 72,71 diameter of the first thread segment is more than the first smooth section 72, is set in the second casing 6 There is cross bar 8, cross bar 8 includes the second thread segment 81 and the second smooth section 82, and 81 diameter of the second thread segment is more than the second smooth section 82, Opening is equipped on the outer wall of 4 and second casing 6 of first sleeve, worm gear 9, worm gear are equipped between 4 and second casing 6 of first sleeve 9 connect decelerating motor by shaft 10, and worm gear 9 is engaged by opening with the first thread segment 71 and the second thread segment 81 respectively, snail Wheel 9 is sequentially connected by the engagement with the first thread segment 71 with counterweight cylinder 7, and worm gear 9 passes through the engagement with the second thread segment 81 It is sequentially connected with cross bar 8, under the driving of decelerating motor, cross bar 8 and counterweight cylinder 7 move round about respectively, reach flat The effect of weighing apparatus.
First thread segment 71 is located at the right part of counterweight cylinder 7, and the second thread segment 81 is located at the left part of cross bar 8.
The right end of the cross bar 8 passes through 11 connection operation hanging basket 12 of cantilever.
Both ends are equipped with limited block 13 on second casing, 6 inner wall, are skidded off out of casing to avoid cross bar 8.This practicality is new Type operation principle is:Under the driving effect of decelerating motor, worm gear and the engagement of the first thread segment realize that worm gear and counterweight cylinder pass Dynamic connection, worm gear and the engagement of the second thread segment realize that worm gear and cross bar are sequentially connected, therefore can realize that cross bar forward extends out same When, counterweight cylinder is stretched backward, also just achievees the purpose that balance.
The utility model is novel in design, simple in structure, can be put down when cross bar stretches by the flexible of counterweight cylinder Weight amount prevents from toppling over to cross bar telescopic direction.
Above-mentioned foundation the utility model is enlightenment, and by above-mentioned description, relevant staff completely can be not In the range of deviateing this item utility model technological thought, various changes and amendments are carried out.This item utility model it is technical Range is not limited to the content on specification, it is necessary to determine its technical scope according to right.
