Abstract

The utility model relates to a flexible trolley cable tackle towing mechanism which comprises a towing supporting seat and a towing tackle. The towing mechanism is characterized in that a chain, shackles, a U-shaped bolt, and two level guide bearings are also included; one end of the chain is connected with the towing supporting seat through the shackle, the other end is connected with the U-shaped bolt through a shackle two, and the U-shaped bolt is fixedly connected with a bracket in the middle of the towing tackle through a nut and a gasket; the two level guide bearings are respectively arranged at the two ends of the vertical travelling wheel of the towing tackle and is provided with the consistent size with bearings which are distributed vertically and form the vertical travelling wheel, the axial lead of the level guide bearings are arranged on the vertical bisection face of the axial lead of the vertical travelling wheel, and is fixed by splicing a multidiameter and the bracket of the tackle. The mechanism can conveniently reach to any needed limit position without the arrangement limit of the tackle to a towing motor vehicle, and at the same time, the mechanism also overcomes the problem that the bidirectional eccentric towing of the common tackle results in seizure and damage.

Description

Flexible dolly cable coaster draw gear

Technical field

The utility model relates to lifting transport establishment industry, relates in particular to a kind of monkey cable coaster draw gear.

Background technology

Monkey adopts the cable coaster conduction, that span is big when occurring, cable dangles is height-limited, vehicle-width is less, when draw bar limited location and the trolley travelling limit also require situation such as less, the total length that cable coaster is arranged when causing dolly to end position surpasses the position of draw bar, dolly adopts the rigid tow bar position that can't reach capacity, and needs a kind of flexible cable coaster draw gear that can bivector traction.On the other hand,, adopts common extension pulley, often cause that coaster and guide rail are stuck, the coaster damage can not move owing to be subjected to eccentric traction if adopt the flexible chain bivector traction.

Summary of the invention

In view of the above-mentioned deficiency of existing in prior technology, the utility model is intended to for rigidity traction occasions with limited provides the flexible dolly cable coaster of a kind of failure-free draw gear, and applicable to off-centre traction, the reverse monkey cable coaster conducting system under traction and the abominable guide rail situation.

Technical solution of the present utility model is achieved in that

A kind of flexible dolly cable coaster draw gear, comprise traction bearing and extension pulley, described extension pulley comprises rubber draft gear, support, rubber pad, cable tray, vertical travelling wheel, it is characterized in that described draw gear also comprises chain, shackle, U-bolt and two horizontally-guided bearings; One end of described chain is connected with the traction bearing by shackle, and the other end is connected with U-bolt by shackle two, and described U-bolt is captiveed joint with the support in the middle of the extension pulley by nuts and washers; Described two horizontally-guided bearings are divided into the two ends of vertical travelling wheel and consistent with the bearing size of the vertical arrangement that constitutes vertical travelling wheel, the axial line of described horizontally-guided bearing is positioned on the vertical bisector plane of axial line of described vertical travelling wheel, and pegs graft fixing by the support of stepped shaft and coaster.

Adopt flexible chain to realize bivector traction between the conduction traction bearing of draw gear described in the utility model and the index coaster, chain slides on U-bolt by shackle two and rotates, and realizes the level and smooth conversion of the forward and reverse traction of chain; On the other hand, because extension pulley set up two horizontally-guided bearings respectively at the vertical travelling wheel two ends of common block, thus often stuck and produce the problem of damaging when having overcome the normal traction coaster and being subjected to eccentric traction.

Compared with prior art, the beneficial effects of the utility model are conspicuous:

The utility model has adopted flexible chain to realize bivector traction, can make dolly not be subjected to coaster to arrange restriction, reaches the end position of any needs easily; Simultaneously, its extension pulley with two-way horizontal guiding can adapt to eccentric traction, oppositely traction and abominable guide rail situation again, thereby it is effective to have a horizontally-guided, and coaster moves characteristics smoothly; This device also has volume characteristics little, simple in structure, easy for installation, and cost is low, life-span length, safe and reliable.

Description of drawings

3 in the utility model accompanying drawing, wherein

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the front view of index coaster;

Fig. 3 is the left view of Fig. 2.

Among the figure, 1, traction bearing 2, shackle 3, chain 4, shackle 25, U-bolt 6, nut 7, packing ring 8, extension pulley 9, rubber draft gear 10, support 11, rubber pad 12, cable tray 13, vertical travelling wheel 14, the bearing 15 of vertical arrangement, horizontally-guided bearing.

The specific embodiment

Now in conjunction with the accompanying drawings, installation of the present utility model and principle of work are described in further detail:

Described flexible dolly cable coaster indexing unit as shown in Figure 1, comprise traction bearing 1, shackle 2, chain 3, shackle 24, U-bolt 5, extension pulley 8, described extension pulley comprises rubber draft gear 9, support 10, rubber pad 11, cable tray 12, vertical travelling wheel 13 and horizontally-guided bearing 15 as shown in Figure 2.

Described draw gear one end adopts bolt group and trolley frame to be connected and fixed by traction bearing 1, traction bearing 1 is connected with flexible chain 3 by shackle 2, the other end of chain 3 is connected with U-bolt 5 by shackle 24, U-bolt 5 is fixedly connected on the support 10 of extension pulley 8 centres by nut 6 and packing ring 7, extension pulley 8 links to each other with the trailing cable of the other end by its cable bracket 12, thereby realizes the flexible drawing of dolly to conductive cable.

Monkey adopts the cable coaster conduction, that span is big when occurring, cable dangles is height-limited, vehicle-width is less, when draw bar limited location and the trolley travelling limit also require situation such as less, the total length that cable coaster is arranged when causing dolly to end position surpasses the position of draw bar, adopt flexible chain to realize bivector traction between this device conduction traction bearing 1 and the extension pulley 8, chain 3 by shackle 24 with U-bolt 5 on slip and rotation, realize the level and smooth conversion of the forward and reverse traction of chain; Simultaneously, because the extension pulley of this device has been set up two horizontally-guided bearings respectively at the vertical travelling wheel two ends of common block, overcome the weakness of frequent stuck damage when the normal traction coaster is subjected to eccentric the traction, can adapt to off-centre draws, oppositely draws and abominable guide rail situation, its horizontally-guided is effective, and the coaster operation is smooth and easy.So then can make the traction power car not be subjected to coaster to arrange restriction, reach the end position of any needs easily by this draw gear.In addition, this device can also reduce the maintenance cost of coaster, and can avoid great potential safety hazard, and is safe and reliable; Estimate that every hoisting crane can save 50,000 yuan of handling cost Renminbi every year.
