However, the safety problems such as torsion and the like occur when the lifting seat slides, and because the lifting seat does not laterally limit the lifting seat when sliding, the lifting seat can sway left and right during lifting, and the danger is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a wind power tower cylinder cat ladder device is favorable to reducing the torsional probability of whole device, improves the security.

In order to achieve the purpose, the technical scheme of the utility model a wind power tower section of thick bamboo cat ladder device is provided, including gimbal mechanism and slide mechanism, gimbal mechanism includes the bottom plate and rotates the winding roller that sets up on the bottom plate, and slide mechanism includes haulage rope, moving member, connecting plate and a plurality of gib block, and every gib block is all fixed on the bottom plate, and the connecting plate is fixed on a plurality of gib blocks, and the moving member slides and sets up on the gib block, and haulage rope one end winding is on winding roller, and the haulage rope is walked around the connecting plate and is connected with the moving member.

The technical effect of the scheme is as follows: the rotation of winding roller drives the rolling of haulage rope, because the haulage rope is connected with the moving member, thereby the moving member slides on the gib block and realizes going up and down. Because the gib block is the prism structure to the moving member is connected with the haulage rope, therefore the moving member slides on the gib block, has reduced the torsional probability of moving member for cylindrical structure. The utility model discloses simple structure, the constructor need not the climbing by oneself, stands on the moving member, rotates the winding roller to realize the rolling of haulage rope, and then realize the lift of moving member, also reduced the emergence of incident when improving the efficiency of construction.

Furthermore, the number of the winding rollers and the number of the guide strips are two, the guide strip connecting plate is provided with through grooves, the connecting plate is provided with two sets of first rope wheels, the first rope wheels are located above the through grooves, two ends of the connecting plate are provided with two sets of second rope wheels, and the traction ropes are wound around the winding rollers, the first rope wheels and the second rope wheels respectively.

Through install first rope sheave and second rope sheave on the connecting plate of gib block, the haulage rope is walked around winding roller, first rope sheave and second rope sheave, can go up and down the moving member sooner. Secondly, the quantity of gib block, first rope sheave and second rope sheave is two, and is more stable at the lift in-process, avoids the moving member atress inequality when the lift to lead to having increased the resistance of going up and down.

Further, each guide strip is H-shaped.

The moving member and the guide bar are in sliding connection, so that the guide bar is H-shaped, the moving member is prevented from being twisted or inclined forwards in the sliding process, and safety is improved.

Further, the moving member is the slip case, and the slip case includes base, backplate and two blocks of curb plates, and base, backplate and two equal fixed connection of curb plate are equipped with the spout on the base, and the slip case passes through spout and gib block sliding connection, is equipped with two sets of third rope sheaves on the base, and winding roller, first rope sheave, second rope sheave and third rope sheave are walked around respectively to the haulage rope.

The setting more than adopting is when being in order to constructor on the slip box, can be close to backplate one side, avoids constructor's focus unstability to lead to forward slope, improves the security. Secondly, install the third rope sheave on the slip case, the haulage rope is walked around winding roller, first rope sheave, second rope sheave and third rope sheave respectively to realize the lift of slip case, install the third rope sheave on the slip case and can cooperate together with other rope sheaves, make the lift of slip case, reduced the resistance that the slip case rises.

Furthermore, a handrail is fixedly arranged on the sliding box.

The arrangement is adopted to provide support for a constructor and prevent the gravity center of the constructor from being unstable.

Furthermore, a motor is connected to the bottom plate through bolts and is connected with the winding roller, the winding roller is located on one side of the sliding box, the traction rope between the winding roller and the sliding box is in a vertical state, and a gap is reserved between the bottom of the sliding box and the bottom plate.

If the haulage rope between second rope sheave and the winding roller is the tilt state, the winding roller is uneven to the power of haulage rope institute, because the motor is connected with the winding roller, consequently the motor also can be stressed unevenly, then the power that the bolt of fixed motor bore is different, then can lead to the bolt to damage to the motor can break away from in the bottom plate. Therefore, the above arrangement is adopted in order to prevent the sliding box from interfering with the wind roller. When the haulage rope is being walked around first rope sheave, second rope sheave and winding roller, because the haulage rope between second rope sheave and the winding roller is in vertical state, so two winding rollers are average to the force of exerting of haulage rope to the atress of motor is also average, prevents that the bolt atress that is used for fixed motor is uneven and damages.

Furthermore, a limiting column is fixedly arranged on the bottom plate, and the sliding box can be in contact with the limiting column.

After the slip box falls to, the constructor when leaving the slip box or getting into the slip box, the slip box can produce certain rocking, and the fixed spacing post that sets up on the floor can play the effect of support to the slip box. In addition, set up spacing post and leave the clearance in order to realize between the bottom of slip case and the bottom plate, guaranteed that the haulage rope between winding roller and the slip case is vertical state to make the motor atress even, be the tilt state for the haulage rope, the haulage rope is vertical state, has reduced the resistance that the slip case rises, thereby the slip case can rise sooner.

Furthermore, a notch is arranged on a base of the sliding box, the limiting column is located at the notch, the notch on the base is an inclined plane, the limiting column is in contact with the notch to form the inclined plane, and the inclined angles of the two inclined planes are different.

By adopting the arrangement, the limiting column plays a role in buffering the sliding seat, and if the inclination angles of the limiting column and the sliding seat are consistent, certain impact force is generated when the sliding seat is contacted with the limiting column, so that certain danger exists. Therefore, the inclined angles of the sliding seat and the limiting column are different, and when the sliding seat is in contact with the limiting column, certain friction force exists, so that the limiting column has a buffering effect on the sliding seat.
