Description
Technical field:
The utility model relates to a kind of structure-improveds of elevator cable tensioning device.
Background technique:
In lift appliance, in order to keep carriage operation more reliable, tensioning apparatus is configured with to the hawser of driving carriage, is passed
The elevator cable tensioning device of system is set there are two tensioning wheel, passes through double threaded screw connection, turn double end between tensioning wheel mounting rack
Screw rod can adjust the distance between two tensioning wheels, to reach the tensioning degree of adjustment elevator cable.And in order into one
Step facilitates adjustment, and cross bar is provided with below tensioning wheel, is equipped with the regulating mechanism of control cross bar height at cross bar both ends, is being tensioned
All hook joint has spring respectively between wheel main shaft both ends and cross bar, and because tensioning wheel is constantly in the state being pulled up, spring, which is held, to be opened
Bearing up pulley main shaft.The rate of tension of elevator cable is adjusted other than can be with turn double threaded screw, it can also be high by adjusting cross bar
Degree is realized.But when adjusting cross bar height by regulating mechanism at present to reach adjusting rate of tension, because spring is that direct hook joint is lived
Cross bar, with turning down for cross bar height, spring straining power will be increasing, when the tightening force of spring is excessive, to rotation
Dynamic double threaded screw adjusts hawser rate of tension with regard to extremely difficult, the reason is that spring excessively tenses cross bar, spring is caused to be difficult to cross
To movement, and then hinder the mobile adjusting of two tensioning wheels.
Summary of the invention:
The shortcomings that the purpose of this utility model is to overcome the above-mentioned prior arts provides a kind of facilitate and adjusts two tensioning wheels
Distance and reach adjust hawser rate of tension elevator cable tensioning device.
The goal of the invention of the utility model can be realized by technical solution below: a kind of elevator cable tensioning device
Structure-improved, include left tensioning wheel and right tensioning wheel, left tensioning wheel is mounted on revolver mounting plate, and right tensioning wheel is mounted on
On right wheel mounting plate, guiding boots are designed in revolver mounting plate tail portion and right wheel mounting plate tail portion, the side for being oriented to boots, which is equipped with, leads
Rail, guiding boots inject in guide rail, and double threaded screw, double threaded screw both ends point are connected between revolver mounting plate and right wheel mounting plate
It is not engaged with revolver mounting plate and right wheel mounting plate at screw thread, is provided with ball below revolver mounting plate and right wheel mounting plate
Sliding rail is equipped with sliding sleeve on ball slide rail, and spring, bullet are equipped between left tensioning wheel and the main shaft and ball slide rail of right tensioning wheel
The main shaft of spring one end hook joint left tensioning wheel and right tensioning wheel, other end hook joint sliding sleeve are both provided with pressure at the both ends of ball slide rail
The firmly compression bar of ball slide rail, compression bar, which is worn, is connected to vertical screw rod, and the upper and lower on vertical screw rod positioned at compression bar is designed with adjusting spiral shell
It is female.
After the technical program, compared with prior art, the technical program is had the advantage that by transmission cross bar
It is changed to ball slide rail, the sliding sleeve on spring hook joint ball slide rail thus may be implemented in the state that spring is excessively tensed,
The distance of two tensioning wheels is still very easy to adjust.
Detailed description of the invention:
Fig. 1 is the facing structure figure of the utility model elevator cable tensioning device；
Fig. 2 is the upper view structure chart of the utility model elevator cable tensioning device.
Specific embodiment:
This technology is described further with reference to the accompanying drawing.
The structure-improved of the elevator cable tensioning device of the present embodiment includes left tensioning wheel 1 and right tensioning wheel 2, a left side
Bearing up pulley 1 is mounted on revolver mounting plate 3, and right tensioning wheel 2 is mounted on right wheel mounting plate 4, hawser a from a upper side downwards successively
Across left tensioning wheel 1 and right tensioning wheel 2, then again upwards, it is designed in 3 tail portion of revolver mounting plate and 4 tail portion of right wheel mounting plate
Boots 5 are oriented to, the side of guiding boots 5 is equipped with guide rail 6, and guiding boots 5 inject in guide rail 6, in revolver mounting plate 3 and right wheel mounting plate 4
Between be connected with double threaded screw 7,7 both ends of double threaded screw are engaged with revolver mounting plate 3 and right wheel mounting plate 4 at screw thread respectively,
The lower section of revolver mounting plate 3 and right wheel mounting plate 4 is provided with ball slide rail 8, sliding sleeve 9 is equipped on ball slide rail 8, in left tensioning
Spring 11, the left tensioning wheel 1 of 11 one end hook joint of spring and the right side are equipped between wheel 1 and the main shaft 10 and ball slide rail 8 of right tensioning wheel 2
The main shaft 10 of bearing up pulley 2, other end hook joint sliding sleeve 9 are both provided with the compression bar 12 for pushing down ball slide rail 8 at the both ends of ball slide rail 8,
Compression bar 12, which is worn, is connected to vertical screw rod 13, and the upper and lower on vertical screw rod 13 positioned at compression bar 12 is designed with adjusting nut 14.
More than, it is only the preferred embodiment of the utility model, limit in any form not is made to the utility model
System.Anyone skilled in the art, in the case where not departing from technical solutions of the utility model ambit, all using above-mentioned
