Abstract
The utility model discloses a rope supporting trolley of a tower crane, which is used for preventing the steel rope lifted from being excessively deflected, abraded or clamped and from falling down. The rope supporting trolley of the tower crane is arranged on an arm frame of the tower crane, and comprises a front vehicle and a rear vehicle; the front vehicle and the rear vehicle are respectively arranged on the two sides of a variable amplitude trolley; the front vehicle and the rear vehicle are connected through a steel rope, and both comprise a bow-shaped frame and two transoms; each transom is provided with horizontal wheels and side wheels; and the front vehicle is also provided with a rope tightening rod. The utility model is characterized in that the bow-shaped frame has an integrative structure; the transoms are arranged at the two sides of the bow-shaped frame; and the middle of the bottom of the bow-shaped frame is provided with a U-shaped supporting roller. The utility model has the advantages of simple structure, small volume, light weight and safe and reliable use, and can effectively prevent the steel rope from being excessively deflected, abraded or clamped and from falling down.
Description
Technical field
The utility model belongs to the elevator machinery technical field, is specifically related to a kind of tower crane holder rope dolly, is used to prevent that the hoist rope downwarp is excessive, weares and teares, blocks and fall arrest.
Background technology
The hoisting capacity and the brachium of present large-scale tower crane constantly increase, and length of steel wire rope and diameter also constantly increase, and the amount of deflection of steel rope also strengthened thereupon when horizontal direction was arranged.The increase of amount of deflection has begun to influence the normal use of tower machine.Even more serious when particularly unloaded, the tower machine operation disturbs in order not make it more than two or on the high-rise building site, must increase tower machine height, wastes energy, and causes construction cost to increase.Already present in the market holder rope dolly roller type is single, and when steel rope was walked in the carrying roller left and right side, this moment, steel rope and side riser were cliding friction, caused steel rope to block easily, enhance faster wear, even pull apart.Therefore safety Design is not enough, and holder rope dolly does not have the fall arrest design, has strengthened the danger of tower machine yet.
Summary of the invention
Technical problem to be solved in the utility model be overcome deficiency of the prior art and provide a kind of simple in structure, volume is little, in light weight, safe and reliable, the tower crane holder rope dolly that can prevent effectively that the steel rope downwarp is excessive, weares and teares, blocks and degenerate.
The technical scheme in the invention for solving the above technical problem is: this tower crane holder rope dolly, be installed on the jib of tower crane, comprise front truck and back car, front truck and back car are installed in the amplitude variation trolley both sides respectively, connect with steel rope between front truck and the back car, front truck, back car constitutes by segmental support and two crosspieces, crosspiece is welded on inboard, segmental support two ends, width is less than the arm frame of tower crane lower boom, crosspiece is provided with horizontal wheel, side wheels and elasticity collision block also are provided with rod for tightening rope on the front truck, be characterized in: described segmental support is an integral structure, crosspiece is arranged on the segmental support both sides, and segmental support is provided with U type support roller in the middle of the bottom.
Its support roller section axial tangent plane of U type support roller described in the utility model is the U-shaped shape.
Crosspiece described in the utility model is welded on inboard, integral type segmental support two ends, and the crosspiece width is less than tower crane jib lower boom.
But side wheels described in the utility model is the aligning side wheels.
The utility model compared with prior art has the following advantages: segmental support adopts integral structure, has alleviated the weight of holder rope dolly self, has improved safety performance.Support roller adopts U type form, is installed in the segmental support central bottom.U type support roller forms approximate semi-ring, can make under the steel rope this moment, a left side and the right side all held, and make steel rope regardless of all being in friction of rolling where, reduced friction, made steel rope not easy to wear, when the horizontal wheel off-axis, because crosspiece is welded on inboard, segmental support two ends, width is less than the arm frame of tower crane lower boom, and crosspiece just hangs on the arm frame of tower crane lower boom, has reached the function of holder rope trolley anti-falling.

The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, holder rope dolly described in the utility model comprises front truck 11 and back car 9, and front truck 11 and back car 9 are installed in amplitude variation trolley 10 both sides respectively, at a distance of 50% left and right sides brachium.Front truck 11, back car 9 constitute by integral type segmental support 3 and two crosspieces 1, crosspiece 1 is welded on inboard, segmental support 3 two ends, crosspiece 1 is provided with horizontal wheel 7, side wheels 6 and elasticity collision block 15, and horizontal wheel 7 hangs on the arm frame of tower crane 8, guarantees to hold in the palm the rope dolly to walk on jib 8 lower booms.But aligning side wheels 6 is buckled on the arm frame of tower crane 8 lower boom sides, and side wheels 6 can be regulated according to jib lower boom width, prevents holder rope dolly left and right sides sideslip, guarantees the steadily walking on jib 8 lower edges of holder rope dolly.Be provided with U type support roller 4 in the middle of integral type segmental support 3 bottoms, U type support roller 4 support roller section axial tangent planes are U-shaped, form approximate semi-ring, 17 times, a left side and the right side are all held can to make hoist rope, make hoist rope 17 no matter all be in friction of rolling, make hoist rope 17 not easy to wear where.Integral type segmental support 3 inboard both sides are separately installed with pulley 5 and becket bridle 16.Also be fixed with rod for tightening rope 2 on the integral type segmental support 3 of front truck 11.The luffing steel rope passes from pulley 5, and steel rope one end that connects two holder rope dollies is fixed on the becket bridle 16 of back car 9, and the other end is fixed on the rod for tightening rope 2 of front truck 11.
During work, when back car 9 was in the jib root, front truck 11 was in the middle of the jib, and hoist rope 17 is divided into two to four sections, thereby reduces hoist rope 17 downwarps.When amplitude variation trolley 10 ahead runnings to front truck 11, promote together ahead running of front truck 11, until operation jib front end, because front truck 11 is connected with back car 9 usefulness steel ropes, thereby car 9 is in the middle of the jib at this moment.Otherwise it is identical.
