Abstract
The utility model discloses a wire rope holds in palm rope device, including holding in the palm rope device (2) and erection support (3), ask rope device (2) including stud shaft (4), packing ring (5), roller (6) and bearing (7), roller (6) both ends are passed through stud shaft (4) and are installed on bearing (7), and install on erection support (3) bearing (7), and erection support (3) are fixed on tower machine steel construction (1), wire rope goes up the process from roller (6), and roller (6) are the axle center with stud shaft (4) and rotate at erection support (3). The utility model discloses wire rope holds in palm rope device, roller can realize rotating on the erection support, let wire rope rather than the contact but not with the steel construction direct contact of tower machine itself, wire rope and roller contact time are short, area of contact is few, the wire rope's that has significantly reduced wearing and tearing.
Description
Technical field
The utility model relates to a kind of tower crane, specifically a kind of steel rope rope supporting device.
Background technology
Existing tower crane is for the use of steel rope, owing to lacking steel rope abrasionproof and rope supporting device, although steel rope directly can not contact with tower machine steel structure under stressed tensioned state in theory, but directly contacting with tower machine steel structure of long-time, long distance can be there is in actual use procedure, therefore in use, steel rope is easy to wear, therefore just there will be following technical disadvantages:
1. steel rope abrasion speed is fast, use and maintenance cost is high.Owing to lacking steel rope shoe, steel rope abrasion speed is fast, reduces its service life, adds the frequency of periodic inspection and maintenance steel rope and more change steel rope, thus causes the use and maintenance cost increasing use user.
2. potential safety hazard is high.Because steel rope abrasion speed is fast and wearing and tearing may be uneven, uncontrollable, therefore steel rope can be caused to occur situation about using in spite of illness, thus there is potential safety hazard.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of steel rope rope supporting device, reduces the wearing and tearing of steel rope, extends the service life of steel rope, improve the safety of craning weight of same, installs simple, quick.
To achieve these goals, the technical solution adopted in the utility model is: a kind of steel rope rope supporting device, comprises rope supporting device and erection support; Described rope supporting device comprises bolt shaft, packing ring, roll shaft, bearing and bolt group; Described roll shaft two ends are arranged on bearing by bolt shaft, and bearing is arranged on erection support, and erection support is fixed on tower machine steel structure; Steel rope is from process roll shaft, and roll shaft is that axle center is rotated at erection support with bolt shaft.
As further improvement of the utility model, described roll shaft is nylon roller.Rigid material of comparing contacts with steel rope, adopts nylon roller to contact with steel rope and can reduce the anti-wear of steel rope further.
As further improvement of the utility model, be layout according to the normal operating condition of steel wire rope system (stressed tension or do not stress lax) and rope, at the opposite site that steel rope passes through, many places rope supporting device be set and be fixed on tower machine steel structure by erection support, preventing steel rope from contacting with steel structure.
As further improvement of the utility model, between bolt shaft and mount pad, packing ring is installed.The pressure of protection attaching parts, reduces scratch, improves service life.
As further improvement of the utility model, described erection support material is angle steel or sheet material.
As further improvement of the utility model, described erection support is by bolt group and tower machine steel structure connection.Also the mode of welding can be adopted to connect, the dismounting but employing bolt group is more convenient for, easy to use.
The utility model steel rope rope supporting device, roll shaft can realize rotating on erection support, allow steel rope be in contact with it but not directly contact with the steel structure of tower machine itself, steel rope and roll shaft contact time is short, area of contact is few, greatly reduces the wearing and tearing of steel rope.Thus there is following advantage:
1. extend the service life of steel rope.Avoid the state that steel rope and steel structure directly wear and tear, effectively ensure that the service life of steel rope.
2. install, dismantle convenient.Installing, dismounting time overall rope supporting device can be installed or removed together, simple operation, simple.
3. novel structure, reliable.Bolt shaft not only plays the effect of fixing nylon roller, also plays the mandrel effect of roll shaft.And roll shaft is nylon material, erection support can realize free rotation, greatly reduce the wearing and tearing of steel rope.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, tower machine steel structure; 2, rope supporting device; 3, erection support; 4, bolt shaft; 5, packing ring; 6, roll shaft; 7, bearing; 8, bolt group.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model steel rope rope supporting device, comprises rope supporting device 2 and erection support 3; Described rope supporting device 2 comprises bolt shaft 4, packing ring 5, roll shaft 6, bearing 7 and bolt group 8; Described roll shaft 6 two ends are arranged on bearing 7 by bolt shaft 4, and bearing 7 is arranged on erection support 3, and erection support 3 is fixed on tower machine steel structure 1; Steel rope is from process roll shaft 6, and roll shaft 6 rotates at erection support 3 for axle center with bolt shaft 4.
On said structure basis, the utility model roll shaft 6 adopts nylon roller, and rigid material of comparing contacts with steel rope, adopts nylon roller to contact with steel rope and can reduce the anti-wear of steel rope further.The utility model is layout according to the normal operating condition of steel wire rope system (stressed tension or do not stress lax) and rope, at the opposite site that steel rope passes through, the opposite site that steel rope passes through, many places rope supporting device 2 be set and be fixed on tower machine steel structure 1 by erection support 3, preventing steel rope from contacting with tower machine steel structure 1.The utility model is provided with packing ring 5 between bolt shaft 4 and mount pad 3.The pressure of protection attaching parts, reduces scratch, improves service life.It is convenient that erection support 3 material of the present utility model adopts angle steel or sheet material to draw materials.
The utility model is after layout is comprehensively analyzed according to the normal operating condition of steel wire rope system (stressed tension or do not stress lax) and rope, at the opposite site that it passes through, install this kind of rope supporting device additional, and can according to the lift heavy performance of tower machine and the design of rope system, the several rope supporting devices carrying out position are in many ways installed, and roll shaft 6, bearing 7, bolt shaft 4 and the packing ring 5 of this rope supporting device 2 using angle steel or sheet material as erection support, adopting nylon to make are arranged on to be fixed on bearing 3 and with bolt or to be welded on tower machine steel structure 1; Nylon roller can realize free rotation, avoids steel rope directly to contact with tower machine steel structure like this, thus reduces, slows down the wearing and tearing of steel rope, reduces the maintenance cost of tower machine.
Certainly, above-described embodiment is only preferred version of the present utility model, is specifically not limited thereto, and can make pointed adjustment according to actual needs on this basis, thus obtain different embodiments.Because mode in the cards is more, just casehistory no longer one by one here.
