Abstract
The utility model relates to a spiral falling and lifting tool of yaw calipers. The falling and lifting tool comprises a thread screw, a hexagon square head is arranged at one end of the thread screw, a support plate and an elongated nut are sleeved on the thread screw, a thrust bearing is arranged at the connection position of the support plate and the elongated nut, and handles are symmetrically arranged on two sides of the elongated nut. The spiral falling and lifting tool of yaw calipers has the advantages that a screw structure is used, and the mounting and the positioning of the yaw calipers are simple and accurate; the work time is shortened, labor intensity of workers is reduced, the work efficiency is improved, and the operation safety is enhanced; and the size is small, the carrying and the mounting are convenient, and the usage is easy.
Description
Technical field
The utility model relates to the spiral decline hoisting tool of a kind of driftage clamp.
Background technology
Along with the maximization of wind-driven generator, be used for the cabin is fixed to driftage brake callipers on the tower cylinder also along with increasing, quantity is also increasing.On-site maintenance to the driftage brake callipers relates to replacing to brake shoes, cleaning, and this just need to take brake callipers apart, and the taking-up brake shoes perhaps cleans brake shoes.But because driftage brake callipers volume is larger, weight is heavier, in addition have surpassed 90 kilograms.So heavy brake callipers is removed, mainly still will lift by manpower at present, the method for using manual chain hoist to pull.Such method labour intensity is large, needs artificial quantity relatively many, and efficiency is low.
The utility model content
The purpose of this utility model provides the spiral decline hoisting tool of a kind of driftage clamp, is used for promoting or dismounting wind driven generator yaw brake callipers, with convenient maintenance to the driftage brake callipers.
The purpose of this utility model is to be achieved through the following technical solutions:
The spiral decline hoisting tool of a kind of driftage clamp, comprise threaded screw rod, threaded screw rod one end is provided with six square toes, and cover has the supporting plate of installation and adds long nut on the threaded screw rod, supporting plate is installed is provided with thrust bearing with the junction that adds long nut, add the long nut bilateral symmetry and be provided with handle.
The beneficial effects of the utility model are: adopt screw-rod structure, the installation location of driftage clamp is simpler, accurately; Shorten the working time, alleviated workman's labour intensity, improved operating efficiency, also improved the security of work; Volume is little, carries, installs all more convenient, is easy to use.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation of the spiral decline hoisting tool of the described driftage clamp of the utility model embodiment;
Fig. 2 is the side view of the spiral decline hoisting tool of the described driftage clamp of the utility model embodiment;
Fig. 3 is the front view of the spiral decline hoisting tool of the described driftage clamp of the utility model embodiment;
Fig. 4 is the A-A cutaway view of Fig. 3.
Among the figure:
1, threaded screw rod; 2, six square toes; 3, supporting plate is installed; 4, add long nut; 5, thrust bearing; 6, handle.
The specific embodiment
Shown in Fig. 1-4, the spiral decline hoisting tool of the described driftage clamp of the utility model embodiment, it comprises threaded screw rod 1, threaded screw rod 1 one ends are provided with six square toes 2, cover has the supporting plate of installation 3 and adds long nut 4 on the threaded screw rod 1, supporting plate 3 is installed is provided with thrust bearing 5 with the junction that adds long nut 4, add long nut 4 bilateral symmetry and be provided with handle 6.
When specifically installing and using, the set bolt on the driftage clamp that at first need to dismantle, this bolt is fixed on the mainframe, then the full thread screw mandrel is screwed in the screwed hole of former set bolt and urgent; Supporting plate and thrust bearing are installed subsequently, and are screwed on and add long nut 4; Weight size according to the driftage clamp determines whether to install second screw body; Then by other bolts of dismounting driftage clamp, unclamp being connected of driftage clamp and mainframe; Slowly the loosening long nut 4 that adds can will rely on gravity to separate from mainframe on the driftage clamp, and the clamp of going off course are slowly dropped to after the suitable distance, carry out cleaning and maintenance or the replacing of brake shoes.After finishing maintenance, add long nut 4 by handle 6 hand rotation, can be like a cork with the lifting of driftage clamp, until revert to former installation position, bolting on gets final product.
The spiral decline hoisting tool of the described driftage clamp of the utility model embodiment utilizes the principle of propeller of screw thread, the weight of driftage clamp is converted into the frictional force of screw rod, thereby workman's labour intensity is reduced greatly, utilize again the effect of thrust bearing 5, the frictional force in the lifting process is reduced to minimum.And adding the use of long nut 4, the position of the clamp of can will going off course easily, efficiently moves up and down.Simple in structure, volume is little, carries, installs all more convenient, and is easy to use, and the location is installed simpler, accurately; Greatly shorten the working time, alleviated workman's labour intensity, improved operating efficiency, also improved the security of work.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
