Description
Technical field
The utility model is related to a kind of cable duct bank resistance-reducing device, it is particularly used for reducing cable row when cable construction
The device of frictional resistance, belongs to cable duct bank engineering device technique field in pipe.
Background technology
In the prior art, cable construction is mostly used the operating mode that cable pulling adds conveyer, and cable relies primarily on conveyer
Thrust move forward.It, then can more setting conveyings in tunnel according to the form of cable tunnel in construction of high voltage cable
Machine, you can complete the laying of cable.But when including the cable construction compared with multi coil form, cable is in direct contact with comb
Generate friction.And the friction coefficient of comb inner cable is generally 0.4, and it is only 0.1-0.2 to use the friction coefficient of idler wheel, can be dropped
Low at least one times of frictional force.Currently, there is no the constructing device for reducing comb internal friction.
Invention content
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide a kind of cable duct bank resistance-reducing device, energy
Enough reduce frictional resistance of the cable in cable duct bank so that cable arrange-line is more smooth, improves cable service life, can be multiple
It reuses.
According to technical solution provided by the utility model, cable duct bank resistance-reducing device includes the drop resistance ontology of circular ring shape,
It is characterized in：It is equipped with cylindrical roller mounting groove in drop resistance ontology inner ring, multiple cylindrical rollers are rotatablely connected in cylindrical roller mounting groove,
Multiple cylindrical rollers are uniformly distributed along cylindrical roller mounting groove circumferencial direction, and the rotating direction of cylindrical roller is that drop hinders this
The axial direction of body；Drop resistance body outer surface, which rolls, connects multiple ball roller bearings, and multiple ball roller bearings hinder ontology circumference along drop
Direction is uniformly distributed.
Further, drop resistance ontology upper edge is axially arranged with several and connects hole.
Further, drop resistance ontology includes two symmetrical hemizonids, and two hemizonids are snapped connection by locking
Integrally.
Compared with the prior art the utility model has the following advantages：
The utility model is simple in structure, compact, reasonable, can repeatedly use, and can reduce cable in cable duct bank
Interior frictional resistance so that cable arrange-line is more smooth, improves working efficiency；Meanwhile improving cable service life.

Fig. 2 is cylindrical roller mounting groove front view.
Reference sign：1- hemizonids, 2- lockings buckle, 3- connect hole, 4- balls roller bearing, 5- cylindrical rollers, 6- circles
Column roller bearing mounting groove.
Specific implementation mode
The utility model will be further described in conjunction with the embodiment in attached drawing below：
As shown in Figure 1 and 2, the utility model includes mainly that the drop of circular ring shape hinders ontology, and drop resistance ontology includes two or so pairs
The hemizonid 1 of title, two hemizonids 1 are linked into an integrated entity by being latched buckle 2.When in use, two hemizonids 1 are sleeved on cable
It is simultaneously locked by being latched buckle 2 on surface.
It is equipped with cylindrical roller mounting groove 6 in drop resistance ontology inner ring, multiple cylinder rollings are rotatablely connected in cylindrical roller mounting groove 6
Axis 5, multiple cylindrical rollers 5 are uniformly distributed along 6 circumferencial direction of cylindrical roller mounting groove, and the rotating direction of cylindrical roller 5
For the axial direction of drop resistance ontology.In use, cable surface is contacted with 5 surface of cylindrical roller, reduces friction.
Drop resistance body outer surface, which rolls, connects multiple ball roller bearings 4, and multiple ball roller bearings 4 hinder ontology circumferencial direction along drop
It is uniformly distributed.In use, 4 surface of ball roller bearing is contacted with cable duct bank inner surface, reduces friction.
The drop resistance ontology upper edge is axially arranged with several and connects hole 3, connects rope and is connected to connect to drive in hole and drops resistance originally
Body connects.
When the utility model is mainly used in cable pipe construction, cable drawing head, can be by this practicality before entering comb
It is novel to be fastened by being latched buckle, it is sleeved on cable, enters cable duct bank together.Ball roller bearing can facilitate the utility model to exist
Sliding in cable duct bank, multiple the utility model connections can be arranged according to cable duct bank length by connecting hole.Cable is in comb
In when moving forward, its rubbing in cable duct bank is reduced by the cylinder roller bearing on the utility model cylindrical roller mounting groove
Wipe resistance.After construction, resistance-reducing device can be pulled out by connecting rope, convenient be repeated as many times utilizes.
