Abstract
An adjustable type flexible roller wheel device comprises a base boom, a first boom frame and a second boom frame, nylon sliding blocks are arranged on the base boom and in the interval between the base boom and the first boom frame, a group or multiple groups of nylon pulley devices are arranged below the base boom and between the base boom and the first boom frame. According to the adjustable type flexible roller wheel device, by the adoption the flexible pulley device, the friction force and the resistance can be reduced, and the power and the energy consumption are lowered. The abnormal sound and vibration of the boom frames under the special work conditions can be eliminated, and the adjustment is convenient after the boom frames are worn.
Description
Technical field:
The utility model relates to a kind of a kind of aerial lift device that relates to, particularly a kind of adjustable flexible roller devices.
Background technology:
The aerial lift device jib is to adopt telescopic oil cylinder and its multistage jib of steel rope control to stretch, and people or thing in the work hurdle are transported to presumptive area, reaches the purpose of its work.At the basic arm and first jib, first jib normally adopts nylon slide block to guarantee with spacing between second jib cooperates with friction, when guaranteeing its relative motion, between do not have bigger resistance and wearing and tearing.Keystone configuration is formed and to be comprised (Fig. 1, Fig. 2) basic arm 1, first jib 2, second jib 3, nylon slide block 4 etc.; Its principle of work shows as first jib 2 and is installed in the basic arm 1; Between the rear and front end by 4 pads of nylon slide block; When the jib fore and aft motion, the phase mutual friction is slided on nylon slide block 4 between jib, guarantees its jib normal operation.
The major defect of prior art: jib is when moving repeatedly, and it is big to be stressed, the nylon slide block easy abrasion, and its resistance of motion is big, and power consumption is big; Jib is worked in particular surroundings, and the inboard dirt slag that gets into of jib adheres to inboardly, during its operation abnormal voice and shake is arranged, maintenance or change and inconvenient after the slider wear, thus influence the maintainability and the service life of equipment.
Summary of the invention
The utility model solves the prior art deficiency and a kind of the have friction force of alleviating and resistance, depowering and energy consumption is provided; The convenient adjustable flexible roller devices of regulating in wearing and tearing back.
A kind of adjustable flexible roller devices; Comprise basic arm, first jib and second jib; Nylon slide block is installed in the spacing on the said basic arm, between said basic arm and first jib, between the below of said basic arm, said basic arm and said first jib one or more groups nylon pulley device is installed.
In the utility model; Said one group of nylon pulley device comprises that with the basic arm axis be symmetrically arranged two nylon pulleys in center; Said nylon pulley is installed on the pulley erecting frame through wheel shaft, and the below of said pulley erecting frame is provided with axis hole, in the said axis hole excentric sleeve is installed; In the said excentric sleeve anchor shaft is installed, said pulley erecting frame is installed on the basic arm through said anchor shaft.
In the utility model, said pulley erecting frame biside plate is provided with the lock screw fixed orifice, the said excentric sleeve of locking is installed in the said fixed orifice prevents the lock screw that excentric sleeve rotates.
Adopt said structure, the advantage of the utility model is: adopt flexible pulley gear can alleviate friction force and resistance, depowering and energy consumption.Eliminate jib abnormal voice and vibrations under special operation condition, make things convenient for its adjusting after the wearing and tearing.
Description of drawings
Fig. 1 is existing telescoping mechanism scheme drawing;
Fig. 2 is along A-A line cut-away view among Fig. 1;
Fig. 3 is the structural representation of the utility model;
Fig. 4 is along A-A line cut-away view among Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description further.
Like Fig. 3 and shown in Figure 4; The utility model is in order to solve the problems of the technologies described above; The cliding friction that it is original changes friction of rolling into; This device is connected to form by nylon pulley 5, wheel shaft 6, pulley erecting frame 7, excentric sleeve 8, lock screw 9 and anchor shaft 10, and wherein nylon pulley 5 is fixed on through wheel shaft 6 and forms an assembly on the pulley erecting frame 7, and its nylon pulley 5 is on wheel shaft 6, to roll around the axle center.Pulley erecting frame 7 offers axis hole, and excentric sleeve 8 passes pulley erecting frame 7 axis holes, connects fixing with pulley erecting frame 7 through excentric sleeve 8 basic arm 1 with anchor shaft 10.
When first telescopic boom 2 is installed in basic arm 1 inboard; By the adjustable flexible roller devices in both sides in the said basic arm 1 to parallel support in first telescopic boom, 2 bottoms and slip; When telescoping mechanism drove first telescopic boom 2 and on basic arm 1, carries out slides in telescopic, nylon pulley 5 was supporting first telescopic boom 2 and is rolling around wheel shaft 6 on its basic arm 1.
The on period jib is moving back and forth, and constantly wearing and tearing in nylon pulley 5 on its middle pulley erecting frame 7 and first telescopic boom, 1 bottom, may wear to a certain degree and can have a strong impact on jib structure intensity and service life.For avoiding this problem to occur; Need its adjustment: pulley erecting frame 7 biside plates are provided with lock screw 9 fixed orifices; Use the accessory appliances inner-hexagon spanner lock screw 9 conter clockwises on the pulley erecting frame 7 are pulled inner-hexagon spanner, unclamp the lock of 9 pairs of excentric sleeves 8 of lock screw and press, clockwise rotate excentric sleeve 8; Excentric sleeve 8 is that rotate in the center of circle with anchor shaft 10; Different because of excentric sleeve 10 circle distribution radiuses, pulley erecting frame 7 and the eccentric rotary of nylon pulley because of excentric sleeve 8 with being enclosed within on the excentric sleeve 10 can carry out change in displacement and realize pulley adjust the clearance purpose.Cw is locked the lock screw 9 on the pulley erecting frame 7 after adjusting to reasonable clearance, to its excentric sleeve 8 lockings, stops excentric sleeve 8 to rotate and gets final product.
Claims (3)
