Detailed Description
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The core of the invention is to provide a first lifting debugging method of a steel wire rope winch lifting type vertical ship lift, wherein the flow schematic diagram of one specific embodiment is shown in figure 1, which is called as a first specific embodiment and comprises the following steps:
s101: the ship reception chamber in a floating state is lifted to the upper lock position.
Of course, the interior of the ship reception chamber in a floating state in this step should be free of water. The locking position may be the highest point that the lifting motor can lift, and the locking may be achieved by a braking mechanism of the wire rope hoisting type vertical ship lift.
Before the step, the ship reception chamber is hung by the steel wire rope, and the lifting motor and the like are in place; the preparation state of the main lifting system equipment specifically comprises the following steps: the reel group and the steel wire rope on the reel group are installed, and two ends of the steel wire rope are respectively arranged at the ship bearing chamber and the installation position of the balance weight; the safety brake system is installed, and all the safety brakes are in a contracting brake state; (the motor and the reducer are power devices of the ship lift, and the safety brake is arranged on a brake disc of the winding drum); completing the no-load test of the main lifting system; the ship carrying chamber lifting device comprises a torque sensor (the torque sensor is connected with a synchronizing shaft and used for detecting torque difference values transmitted by different lifting points when the synchronizing shaft rotates), a synchronizing shaft system is in place, the synchronizing shaft system (the synchronizing shaft is a mechanical synchronizing device used for connecting a plurality of motors in series on a ship lifting main system, and the rotating speed of all the motors is in the same mechanical state, so that different lifting points cannot have different speeds to cause the ship carrying chamber to incline in the lifting process of the ship carrying chamber), and the ship carrying chamber is released from temporary limit facilities on water. The ship lift referred to in the present invention can be further appreciated by referring to fig. 2, and fig. 2 is a schematic structural view of the ship lift according to the present invention.
Specifically, the brake assembly includes a safety brake and a service brake, and is respectively mounted on the brake disc of the winding drum and the output shaft of the lifting motor, and of course, other types of brakes can be selected according to actual needs.
S102: and the steel wire rope is wound around the lifting motor and connected with the ship receiving chamber and the balance weight positioned at the lower locking position.
In actual construction, the main hook and the auxiliary hook of the main machine room 1600 KN/2X 160KN bridge crane can be matched to be respectively hoisted to the lower locking position of the counterweight well by the counterweight.
As a preferred embodiment, before this step, the method further comprises:
adjusting the adjusting screws of all the balance weights to the same elevation position. Adjusting the adjusting screw of the balance weight to the same elevation position can greatly facilitate the connection of subsequent steel wire ropes, and simultaneously, after the subsequent ship lift is put into use, the posture condition of the ship receiving chamber can be determined according to the position of the adjusting screw.
Furthermore, the elongation of the adjusting screw rods of all the balance weights is adjusted to the middle position, and the elongation of the adjusting screw rods is adjusted to the middle position, so that when the position of the balance weights is adjusted by the subsequent adjusting screw rods, a margin is left for adjustment in two directions, and the flexibility of adjusting and using the ship lift is greatly increased.
As a specific embodiment, the step specifically includes:
a wire rope that is passed around the hoisting motor and has one end connected to the ship reception chamber is manually tensioned and the other end is connected to a counterweight located in the lower lock position.
In the preferred embodiment, before the components at the two ends of the steel wire rope are connected, the steel wire rope is manually tensioned, so that the impulse applied in the subsequent tensioning process of the steel wire rope is further reduced, and the safety is improved.
S103: setting a first moment for the lifting motor, and lowering the ship receiving chamber to automatically stop the lifting motor; the first moment is smaller than the weight difference between the balance weight and the ship receiving chamber.
In the following, the step is described by way of example, the weight of the counterweight in the step is 2300 tons, and the weight of the ship bearing compartment is 790 tons, obviously, the weight difference between the two is too large, the lifting motor is not enough to compensate the weight difference between the two when applying the pre-applied first torque (set as the rated torque of the lifting motor is 1200 tons, and the peak torque is 1800 tons), which may result in a failure of lowering the ship bearing compartment, and then the lifting motor may directly alarm to stop, and the safety brake and the service brake may automatically lock up, in this process, a tensioning of the steel wire rope is completed, and the lifting motor is used for buffering in the tensioning process, so that the impact effect of the ship bearing compartment dropping on the steel wire rope is reduced.
S104: and injecting water into the ship reception chamber, and obtaining the balance water level data of the steel wire rope hoisting type vertical ship lift according to engineering parameters obtained in the water injection process.
In the step, water is injected into the ship reception chamber, so that the weight of one end of the ship reception chamber is gradually increased, and finally the balance water level data is determined by observing the state of the balance weight end. Of course, in order for the forces of the ship reception compartment to be transmitted to one end of the counterweight through the wire rope during the water filling process, it is necessary to release the brake assembly and to de-energize the hoisting motor.
The balance water level data refers to the relevant parameters of the water level in the ship reception chamber when the weight of the ship reception chamber end is equal to that of the balance weight end.
According to the first lifting debugging method of the steel wire rope winch lifting type vertical ship lift, the ship receiving chamber in a floating state is lifted to the upper locking position; the steel wire rope is wound around a lifting motor and connected with the ship receiving chamber and a balance weight positioned at the lower locking position; setting a first moment for the lifting motor, and lowering the ship receiving chamber to automatically stop the lifting motor; the first moment is smaller than the weight difference between the balance weight and the ship receiving chamber; and injecting water into the ship receiving chamber, and obtaining the balanced water level data of the steel wire rope hoisting type vertical ship lift according to engineering parameters obtained in the water injection process. Different from the method of directly emptying the steel wire rope and enabling the rope to instantly and completely bear the ship bearing chamber in the prior art, the method avoids that the steel wire rope bears the gravity of all the balance weights and the gravity of the ship bearing chamber at the moment of releasing the brake assembly, utilizes the lifting motor as a buffer, shares a part of the lifting motor applying the first moment at the moment of releasing the brake, reduces the impulse borne by the steel wire rope, thereby ensuring the structural integrity of the steel wire rope, greatly reducing the possibility of accidents and improving the debugging safety of the ship lift.
On the basis of the first specific embodiment, a method for setting the magnitude of the first moment is further defined to obtain a second specific embodiment, a flow diagram of which is shown in fig. 3, and includes:
s201: the ship reception chamber in the floating state is lifted to the upper locking position.
S202: and the steel wire rope is wound around the lifting motor and connected with the ship receiving chamber and the balance weight positioned at the lower locking position.
S203: and acquiring a first weight difference between the balance weight and the ship reception chamber and the weight of the ship reception chamber.
S204: and judging whether the first weight difference is larger than the weight of the ship receiving chamber.
S205: and when the first weight difference is larger than the weight of the ship reception chamber, adopting the moment of the weight of the ship reception chamber as a first moment, setting the first moment for the lifting motor, and lowering the ship reception chamber to automatically stop the lifting motor.
S206: and injecting water into the ship receiving chamber, and obtaining the balanced water level data of the steel wire rope hoisting type vertical ship lift according to engineering parameters obtained in the water injection process.
The difference between the present embodiment and the foregoing embodiment is that a specific method for determining the first moment is provided in the present embodiment, and the remaining steps are the same as those in the foregoing embodiment, and are not described herein again.
In this embodiment, the weight of the ship reception chamber and the weight difference between the counterweight and the ship reception chamber are compared, when the weight of the counterweight is greater than twice the weight of the ship reception chamber, the weight of the ship reception chamber is directly used as the first moment, and it should be noted that if the first moment is too small, a good buffering effect cannot be achieved, but if the first moment is too large, the weight of the ship reception chamber is exceeded, a risk that the ship reception chamber is suddenly dropped is increased, and therefore, directly using the first moment equal to the weight of the ship reception chamber is an optimal solution.
As a preferred embodiment, the determining whether the first weight difference is greater than the weight of the ship reception chamber includes:
a1: and judging whether the difference value between the first weight difference and the weight of the ship receiving chamber is greater than a first threshold value.
Correspondingly, when the first weight difference is larger than the weight of the ship reception chamber, adopting the moment of the weight of the ship reception chamber as the first moment comprises the following steps:
a2: and when the difference value between the first weight difference and the weight of the ship reception chamber is larger than a first threshold value, adopting the moment of the weight of the ship reception chamber as a first moment.
In the preferred embodiment, the first threshold is introduced, that is, the weight of the ship receiving chamber is not only greater than the first threshold, but also cannot be too close to the first threshold, and a part of margin should be left, so as to avoid an accident caused by the fact that the sum of the weight of the ship receiving chamber and the first moment is greater than the weight of the counterweight due to an error in measuring the weight of the ship receiving chamber and the counterweight. The preferred embodiment greatly reduces the possibility of accidents and improves the safety in the installation process.
As a specific implementation manner, after determining whether the first weight difference is greater than the weight of the ship reception chamber, the method further includes:
and when the first weight difference is not more than the weight of the ship reception chamber, the balance weight is weighted.
The weight of the balance weight is more than twice of that of the ship bearing chamber, the stable operation of the ship lift in actual work can be guaranteed, accidents are avoided, and the work safety is improved.
On the basis of the first specific embodiment, a method for obtaining the balanced level data is further defined to obtain a third specific embodiment, and a corresponding flow diagram is shown in fig. 4, and includes:
s301: the ship reception chamber in a floating state is lifted to the upper lock position.
S302: and the steel wire rope is wound around the lifting motor and connected with the ship receiving chamber and the balance weight positioned at the lower locking position.
S303: setting a first moment for the lifting motor, and lowering the ship receiving chamber to automatically stop the lifting motor; the first moment is smaller than the weight difference between the counterweight and the ship receiving chamber.
S304: and releasing the brake assembly and keeping the lifting motor in a non-excitation state.
The brake assembly is loosened before water injection, the lifting motor is closed (the lifting motor is in a non-excitation state), so that the load of the steel wire rope is gradually increased along with the injection of water flow, the phenomenon that the load of the steel wire rope is suddenly increased due to the fact that the brake assembly is loosened and the lifting motor is closed after water is added to a certain degree is avoided, the debugging safety can be further guaranteed, and equipment is prevented from being damaged.
Since the tensioning is performed once before, the brake assembly is directly released after step S303, and the hoisting motor is kept in the non-excited state, the impact on the wire rope is also small.
S305: and injecting water into the ship reception chamber until the balance weight leaves the lower locking position, and recording the corresponding water level in the ship reception chamber as a basically equal-weight water level.
The steel wire rope is gradually tensioned along with the increase of the water carrying capacity in the ship bearing chamber, the tension force borne by the balance weight is increased, in the step, water injection is stopped when the balance weight leaves the lower locking location, the fact that the balance weight leaves the lower locking location indicates that the water is injected, the weight of the ship bearing chamber carrying water is basically the same as that of the balance weight, and the water level at the moment is the basically equal-weight water level.
S306: and starting the lifting motor to enable the ship receiving chamber to descend for a first distance to obtain the starting torque of the lifting motor.
And starting the lifting motor, setting a pre-applied torque, driving the ship bearing chamber to move downwards for the first distance (for example, 1m, which can be selected according to actual conditions), recording initial data of the lifting motor at the moment, wherein the starting torque is the weight difference between the ship bearing chamber and the balance weight.
S307: and determining the balanced water level data according to the basic equigravity water level and the starting torque.
The previous step is that the starting moment of the lifting motor is the weight difference between the ship reception chamber and the balance weight, and the weight difference can be converted into the water volume in the ship reception chamber and further converted into the water level, namely the balance water level.
The balance water level is the water level of the ship reception chamber with water consistent with the weight of the balance weight, and the data can be used as important basic data when a subsequent ship lift operates and overhauls.
The difference between the present embodiment and the foregoing embodiment is that a specific method for determining the first moment is provided in the present embodiment, and the remaining steps are the same as those in the foregoing embodiment, and are not described herein again.
In the present embodiment, a method for measuring the equilibrium water level data is specifically provided, compared with the prior art, the present embodiment is divided into two steps to obtain an accurate equilibrium water level, wherein the first step "filling water until the counterweight leaves the lower lock position" is determined by visual observation, but there is no error, because no matter the water in this step is added or added too little, the starting torque of the lifting motor in the next step is corrected, and therefore, the present embodiment greatly improves the measurement accuracy of the equilibrium water level.
