Description
Technical field
The utility model relates to controlling to adjust device, is specifically related to a kind of chain block test machine for service life.
Background technology
Chain block is a kind of Manual hoisting machinery simple, easy to carry, and it is applicable to the short distance handling of mini-plant and goods.
The principle of chain block is: the chain-driving driver pinion pulled rotates, and little gear driven bull gear drive, speed slows down, power
Square increases, such that it is able to use the power more much smaller than weight, weight of slinging.A click machine is had in the inner side pulling chain
Structure, makes sprocket wheel to rotate in a direction
Chain block is in type approval test or dispatches from the factory in sampling observation, needs to bear great load and speed when detecting handling and unloading, with
Time in order to ensure the safety and reliability of cucurbit, need cucurbit is carried out life tests, but currently available technology can't be to cucurbit
Life tests well controls.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of chain block test machine for service life.
The purpose of this utility model is realized by such technical scheme, and a kind of chain block test machine for service life, including suspention
Frame, control module, switch, motor, eccentric wheel and hydraulic cylinder, described pipe-hanging hook includes a back timber and two columns, described cucurbit
Being connected on back timber, described hydraulic cylinder is arranged at the lower section of back timber, and the piston rod of hydraulic cylinder is connected with the hook of cucurbit；Described motor
Line shaft be connected with the central shaft of eccentric wheel, the eccentric shaft of described eccentric wheel is connected with cucurbit by connecting rod, and described control module is logical
Cross switch to be connected with motor.
Further, also including reversing arrangement, control module is connected with cucurbit by reversing arrangement.
Further, also include that torque sensor, described torque sensor are connected with motor and control module respectively.
Further, also include that range sensor, described range sensor are connected with hydraulic cylinder and control module respectively.
Further, the audible-visual annunciator being connected with control module is also included.
Owing to have employed technique scheme, the utility model has the advantage that
The utility model can detect chain block can bear great load and speed when handling and unloading, and its detection efficiency is high,
Testing result is accurate, and realizes simple, easy to operate.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model made into
The detailed description of one step, wherein:
Fig. 1 is theory diagram of the present utility model；
Fig. 2 is structure chart of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail；Should be appreciated that preferred embodiment is only
In order to the utility model being described rather than in order to limit protection domain of the present utility model.
A kind of chain block test machine for service life, including pipe-hanging hook, control module, switch 4, motor 3, eccentric wheel 1 and hydraulic pressure
Cylinder 7, described pipe-hanging hook includes a back timber and two columns, and described cucurbit is connected on back timber, and described hydraulic cylinder is arranged at back timber
Lower section, the piston rod of hydraulic cylinder is connected with the hook of cucurbit 8；The line shaft of described motor is connected with the central shaft of eccentric wheel, described
The eccentric shaft of eccentric wheel is connected with cucurbit by connecting rod, and described control module is connected with motor by switch.
In the present embodiment, control module is PLC control module.
As the improvement to the present embodiment, also including reversing arrangement 5, control module is connected with cucurbit by reversing arrangement.
As the improvement to the present embodiment, also including torque sensor, described torque sensor 2 connects with motor and control module respectively
Connect.Torque sensor in the course of the work, detects Motor torque.When cucurbit spanner blocks or modification, moment of torsion can excessive or cucurbit tooth
When wheel ruptures, moment of torsion is too small, after PLC detects, quit work at once.
As the improvement to the present embodiment, also include range sensor, described range sensor 6 respectively with hydraulic cylinder and control module
Connect, the distance that range sensor detection hydraulic cylinder piston rod rises.
As the improvement to the present embodiment, also include the audible-visual annunciator being connected with control module.
Operation principle of the present utility model is:
1, PLC sets the oil pressure of oil cylinder；2, PLC starts motor；3, driven by motor eccentric wheel rotate with, rocking bar is become on
Lower motion, makes cucurbit work, is lifted up hydraulic cylinder；4, detect that the piston rod of hydraulic cylinder rises to assigned position as PLC,
PLC controls the direction of reversing arrangement switching cucurbit, is allowed to downward；The most eccentric rocking bar moves upward, when PLC detects hydraulic pressure
Cylinder drops to regulation when putting, and PLC controls the direction of reversing arrangement switching cucurbit, so circulates, until reaching the number of times set.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, it is clear that the technology of this area
Personnel can carry out various change and modification without deviating from spirit and scope of the present utility model to the utility model.So, if originally
These amendments of utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model
It is also intended to comprise these change and modification.
