Description
Technical field
The utility model relates to a kind of rope device that falls, and specifically a kind of overhead traveling crane falls rope device.
Background technology
The overhead traveling crane steel rope has the system of periodic inspection, has reached to scrap hempcore cable and can not continue to use, and should change immediately, to eliminate safe hidden trouble.And the replacing of traditional steel rope mainly is progressively to spur by driving new steel rope with old rope; Slowly it is replaced, must about 30 surplus the people shouldering rope and moving step by step, rope is slowly upwards postponed under the manpower pulling; Until replacing, whole process expends tens hours approximately.The method of this replacing takes time and effort, and is easy to generate the phenomenon that steel rope takes off groove, card rope and mill rope, and need takies very big site space.
The utility model content
The purpose of the utility model just provides a kind of overhead traveling crane and falls rope device, is prone to tighten, tie dog leg and changes rop exercise and make the problem that wastes time and energy to solve in the process of changing overhead traveling crane steel rope steel rope.
The utility model is achieved in that a kind of overhead traveling crane falls rope device, include with overhead traveling crane steel rope quantity suitable go up rope support and with the said identical following rope support of the quantity of falling the rope support of going up; The said rope support that upward falls is to be respectively arranged with the fixed pulley group at the two ends of fixed mount, and said fixed pulley group is in wheel carrier, to be provided with groove face two involutory fixed pulleys up and down; The said rope support that falls down is through the bearing assembly support and connection steel rope winding mechanism to be arranged at the two ends of support.
Said wheel carrier is the osed top rectangular frame structure, and two said fixed pulleys are fixedly connected on respectively on the upper frame and underframe of said wheel carrier.The occlusion structure of two fixed pulleys has avoided take off groove, card rope and the mill of steel rope to restrict.
The two ends of the upper frame of said wheel carrier are connected the stand upper end of said wheel carrier through fastener.
One end of the upper frame of said wheel carrier is hinged in the stand of said wheel carrier, and the other end of upper frame is connected in another stand of said wheel carrier through fastener.
Said steel rope winding mechanism is the reel on belt wheel limit, two ends, and cross-under has spool in said reel.
Said steel rope winding mechanism is to be respectively arranged with interstage sleeve at the two ends of a spool.
Said steel rope winding mechanism is the reel on belt wheel limit, two ends, is provided with outwardly directed support semiaxis at the two ends of said reel.
The utility model is simple in structure, and is economical and practical, and easy accessibility changes the restriction that rop exercise does not receive narrow zone and working environment.The utility model has been saved manpower and time in the operating process that renews rope, reduced labour intensity, has saved the space, has reduced place zone requirement.

Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of falling the rope support of going up of the utility model.
Fig. 3 is the following bearing assembly of rope support of the utility model and the structural representation of winding mechanism.
Among the figure: 1, fall rope support down, 2, upward fall rope support, 3, fixed mount, 4, underframe, 5, wheel carrier, 6, upper frame, 7 fixed pulleys, 8, reel, 9, bearing assembly, 10, spool.
The specific embodiment
As shown in Figure 1, the utility model include with overhead traveling crane steel rope quantity suitable go up rope support 2 and with the last identical following rope support 1 that falls of rope support 2 quantity that falls.Change steel cable and need a pair of go up rope support 2 and a pair of rope support 1 that falls down.It is all detachable with the each several part of following rope support 1 to go up rope support 2.Going up rope support 2 can make with common iron with following rope support 1.
As shown in Figure 2, the rope support 2 that upward falls is to be respectively arranged with the fixed pulley group at the two ends of fixed mount 3, and the fixed pulley group is in wheel carrier 5, to be provided with groove face two involutory fixed pulleys 7 up and down.Wheel carrier 5 is the osed top rectangular frame structure, and two fixed pulleys 7 are fixedly connected on respectively on the upper frame 6 and underframe 4 of wheel carrier 5.The two ends of the upper frame 6 of wheel carrier 5 are connected the stand upper end of wheel carrier 5 through fastener.One end of the upper frame 6 of wheel carrier 5 is hinged in the stand of wheel carrier 5, and the other end of upper frame 6 is connected in another stand of wheel carrier 5 through fastener.
As shown in Figure 3, the rope support 1 that falls down is through bearing assembly 9 support and connection the steel rope winding mechanism to be arranged at the two ends of support.Winding mechanism is the reel 8 on belt wheel limit, two ends, and cross-under spool 10 in reel 8 is in the two end supports connection bearing assembly 9 of spool 10.
The working process of the utility model is: at first overhead traveling crane is rested in the appropriate location, change rop exercise and do to divide upper and lower two parts, carry out simultaneously on ground and the overhead traveling crane.
When changing an old steel rope, the case of a pair of last rope support 2 through the assembly pulley of welding or bolt and gantry suspension hook fixed.Put down gantry suspension hook then, old steel rope is put in the middle of the two-wheeled, the fixed pulley 7 in the last conductor rope frame 2 can be opened through the effect of upper frame 6 and underframe 4, with the old steel rope of convenient folder.
The a pair of rope support 1 that falls down is put in respectively on the ground of portal frame both sides, the new steel rope of whole dish is placed to fall under the side on the reel 8 of rope support 1; The fag end of old steel rope is extracted stretching (being not less than 10 meters) is put on the ground, with four volumes different twist with the fingers to new steel rope falling down by direction position pendulum on the rope support, notice that every group is twisted with the fingers to looking-glass symmetry.Extract a fag end and balance stretching welding (gas welding welding, postwelding is carried out insulation and handled) with old steel rope.
After all work are all ready, utilize the transmission facility of overhead traveling crane then, drive down the reel 5 of rope support 1 simultaneously; With regard to the new method of available old band with steel rope replacing; Old then steel rope is wrapped on the following rope support 1 of opposite side, after old rope has all been put through on opposite side, falling rope support 2; Cut off joint, change the knot bundle to this.
