The principle of chain block is: the chain-driving driver pinion rotation pulling, and pinion wheel drives gear wheel to rotate, and speed slows down, and moment increases, thereby can use than the little a lot of power of weight, the weight of slinging.There is a ratchet and pawl arrangement in the inner side that pulls chain, sprocket wheel can only a direction be rotated.
Chain block is in type approval test or dispatch from the factory in sampling observation, need to detect handling and unloading time can be born great load and speed.But this detection need to pull chain by staff, speed is very slow, and detection efficiency is very low, can not adapt to the needs of factory's large-scale production.
While detection in addition, adopt and pull, the power that different people draws is different, causes the error ratio of testing result larger.
Therefore, improve chain block and detect machine, improve detection efficiency, make testing result more accurate, and realize simply, easy to operate, be this area technical issues that need to address.
Utility model content
The technical problems to be solved in the utility model: chain block can bear in the project of great load and speed in the time detecting handling and unloading, the problem that detection efficiency is very low, testing result error is large.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of chain block detects machine, comprises pipe-hanging hook, pulling force sensor, hydraulic cylinder, hydraulic control system and runner motor; Described pipe-hanging hook comprises a back timber and two columns, and described pulling force sensor hanging is arranged on described back timber, and is provided with the hook being connected with described chain block; Described hydraulic cylinder is vertically mounted on the ground of described back timber below, and its piston rod is connected with the hook being connected with described chain block; Described hydraulic cylinder limit is provided with the hydraulic control system of controlling described hydraulic cylinder; Described runner motor is arranged on the middle part of described column, and the sprocket wheel that pulls chain that connects described chain block is housed on its output shaft, and described output shaft is horizontal positioned.
Preferably, the height that described runner motor is installed is apart from ground 1 meter.
Preferably, described runner motor is a kind of stepper motor.
Preferably, described hydraulic cylinder is a kind of oil hydraulic cylinder.
Preferably, the major part of described oil hydraulic cylinder is at described below ground, and described ground is provided with the pit that holds oil hydraulic cylinder.
Pass through technique scheme, the utility model is hung a pulling force sensor on the back timber of a pipe-hanging hook, on ground below support, be provided as the hydraulic cylinder of load, then the upper end of chain block is hung on pulling force sensor, the chain of lifting is connected to hydraulic cylinder, by the column middle part at pipe-hanging hook, a runner motor is set again and replaces pulling of staff, the speed of motor is adjustable, also can rotating.Pulling of both direction by motor, can detect chain block and can bear great load and speed in the time of handling and unloading.Its beneficial effect is that detection efficiency is high, and testing result is accurate, and realizes simple, easy to operate.

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram that the disclosed chain block of the utility model embodiment detects machine.
Numeral and the represented corresponding component title of letter in figure:
1. back timber 2. column 3. pulling force sensor 4. hydraulic cylinder 5. hydraulic control system 6. runner motors
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Principle of the present utility model is: on the back timber of a pipe-hanging hook, hang a pulling force sensor, on ground below support, be provided as the hydraulic cylinder of load, then the upper end of chain block is hung on pulling force sensor, the chain of lifting is connected to hydraulic cylinder, by the column middle part at pipe-hanging hook, a runner motor is set again and replaces pulling of staff, the speed of motor is adjustable, also can rotating.Pulling of both direction by motor, can detect chain block and can bear great load and speed in the time of handling and unloading.
Embodiment.
As shown in Figure 1, a kind of chain block detects machine, comprises pipe-hanging hook, pulling force sensor 3, hydraulic cylinder 4, hydraulic control system 5 and runner motor 6; Pipe-hanging hook comprises a back timber 1 and two columns 2, and pulling force sensor 3 hangings are arranged on back timber 1, and are provided with the hook being connected with chain block; Hydraulic cylinder 4 is vertically mounted on the ground of back timber 1 below, and its piston rod is connected with the hook being connected with chain block; Hydraulic cylinder 4 limits are provided with the hydraulic control system 5 of controlling hydraulic cylinder 4; Runner motor 6 is arranged on the middle part of column 2, and the sprocket wheel that pulls chain that connects chain block is housed on its output shaft, and output shaft is horizontal positioned.
In the present embodiment, the height that runner motor 6 is installed is 1 meter apart from ground.This is the service condition that pulls chain in order to simulate accurately staff, because staff while pulling, is generally the operation of standing, people's hand is in drawing, apart from the height on ground, probably 1 meter of left and right.
