Property.
Coefficient of balance during in order to accurately measure elevator no-load, hydraulic cylinder 4 are two, and force cell 3 is two
It is individual；One of hydraulic cylinder 4 is arranged on upper left fixture block 11；Another hydraulic cylinder 4 is arranged on upper right fixture block 12, two dynamometry
Sensor 3 is respectively used to measure the pressure value of two hydraulic cylinders, using two hydraulic cylinders 4 and two force cells 3, Ke Yiyou
Evade using the inaccurate situation of appearance measurement at one on effect ground.Certainly, in order to facilitate the peace of hydraulic cylinder 4 and force cell 3
Dress, arm-tie 6 of the invention are also two.
In order to which upper left fixture block 11 and upper right fixture block 12 are fixed together, as shown in figure 1, present invention additionally comprises eight groups
Fastening assembly, fastening assembly includes screw rod 8 and nut (not shown), screw rod 8 sequentially pass through upper right fixture block 12 and upper left fixture block 11,
Four nuts are spirally connected with screw rod 8, so as to which upper left fixture block 11 and upper right fixture block 12 be tightened together, make upper left fixture block 11 and upper right
Fixture block 12 clamps the top of selected traction ran.Similarly other four groups of fastening assemblies are also by lower-left fixture block 21 and bottom right fixture block
22 tighten together, and lower-left fixture block 21 and bottom right fixture block 22 is clamped the lower section of selected traction ran.Certain fastening assembly
The several evidences of group be actually needed and be determined.In order to be skidded when preventing screw rod 8 from dropping and fastening, as shown in Figure 1, Figure 2 and Figure 3,
On upper right fixture block 12 and bottom right fixture block 22 is respectively equipped with anti-screw rod skidding groove 82, is beaten when dropping or fasten for anti-screw rod
It is sliding.After screw rod 8 passes through anti-screw rod skidding groove 82, anti-screw rod skidding groove 82 is covered with cover plate 81.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, traction ran is specifically described the present invention by taking steel wire rope as an example.
If steel wire rope is 7；First hydraulic cylinder 4 is arranged on the connecting portion of upper left fixture block 11, by first dynamometry
Sensor 3 is arranged between the first arm-tie 6 and the first connector；Second hydraulic cylinder 4 is arranged on to the connection of upper right fixture block 12
In portion 121, second force cell 3 is arranged between the second arm-tie 6 and the second connector；Fixture block 11, upper right in upper left
Cushion block 7 in being placed on fixture block 12, lower-left fixture block 21 and bottom right fixture block 22.
By seven holding tanks 71 of the interior cushion block 7 being placed in above seven steel wire ropes in upper left fixture block 11 and upper right fixture block 12
Between；It will be placed in below seven steel wire ropes between seven holding tanks 71 of the interior cushion block 7 of lower-left fixture block 21 and bottom right fixture block 22；
The connection of upper fixture 1 and lower clamp 2 is realized by lifting arm 5；By wherein four groups of fastening assemblies to upper left fixture block
11 and upper right fixture block 12 apply fastening force, and then to the interior cushion block 7 of upper left fixture block 11 and upper right fixture block 12 apply chucking power, to seven
The top of bar steel wire rope, which is realized, to be clamped；Equally, lower-left fixture block 21 and bottom right fixture block 22 are applied by other four groups of fastening assemblies
Fastening force, and then chucking power is applied to the interior cushion block 7 of lower-left fixture block 21 and bottom right fixture block 22, the lower section of seven steel wire ropes is realized
Clamp；
After clamping, realize that the hydraulic stem of hydraulic cylinder 4 jacks up upwards by carrying out oil-feed to hydraulic cylinder interface 41, drive carries
Rising stem 5 is raised above, and then can realize the lifting of lower clamp 2, so that the steel wire rope that interlude clamps is in relaxation shape
State, as shown in fig. 6, force cell 3 directly records the weight of hoisting elevator car 91 and counterweight 92, realize the survey of coefficient of balance
Amount.
Below, illustrate that the detection of the elevator no-load coefficient of balance detection means based on hydraulic cylinder straight top type of the present invention is former
Reason.
As shown in fig. 6, when balance coefficient of elevator detects, it is top that lift car 91 and the priority of counterweight 92 are moved to hoistway
Position, the balance coefficient of elevator detection means is installed in computer room.
When the zero load of lift car 91 be placed in hoistway it is top and static when, as shown in Figure 6 installation the present invention based on hydraulic pressure
The balance coefficient of elevator detection means of cylinder straight top type, ignore the frictional force that car leads boots and guide rail in of the invention.So such as Fig. 1 institutes
Show, if now exerted a force to hydraulic cylinder 4, realize the rising of lifting arm 5, then the stress of steel wire rope tapers into, the liquid of hydraulic cylinder 4
The stress of cylinder pressure becomes larger, if after steel wire rope is in the state that do not stress, continues to upwards slowly at the uniform velocity exert a force to hydraulic cylinder 4,
Continue to lift up lifting arm 5, until folded steel wire rope is fully relaxed.It is measurable to obtain static state after the movement of lift car 91 stops
When cage side weight G.
Similarly, the amount of the stressing W of the counterweight 92 when obtaining static state.
Then, by counterweight-side weight W when cage side weight G during elevator static state and elevator static state, it is updated to balance system
In number algorithmic formula K=(W-G)/Q, K is coefficient of balance, and W is counterweight-side weight, and G is cage side weight, and Q is the specified of elevator
Loading capacity.So as to obtain static balancing COEFFICIENT K=(W-G)/Q of elevator.
Specific detection method includes：
The step of clamping traction ran, choose draging as detection target above the side of lift car 91 top or the side of counterweight 92
Messenger section, the traction ran is clamped respectively using upper fixture 1 and lower clamp 2；
The step of hydraulic cylinder 4, hydraulic cylinder 4 are arranged in upper fixture 1, by connector, force cell 3, arm-tie 6 and carried
Rising stem 5 connects lower clamp 2；
Read data the step of, operate hydraulic cylinder 4 hydraulic stem hoisting elevator car 91 or counterweight 92, upper fixture 1 with
After the traction ran between lower clamp 2 is in the state that do not stress, the pressure value of the hydraulic stem of hydraulic cylinder 4 is measured, respectively
To counterweight-side weight W during cage side weight G or elevator static state during elevator static state；With
The step of calculated equilibrium coefficient, by counterweight-side weight W when cage side weight G during elevator static state and elevator static state
Substitute into coefficient of balance algorithmic formula K=(W-G)/Q, wherein, K is coefficient of balance, and W is counterweight-side weight, and G stresses for car
Amount, Q are the nominal load capacity of elevator, obtain static balancing COEFFICIENT K=(W-G)/Q of elevator.
