Abstract
The utility model discloses an adjustable feeding system of a concrete wet-spraying machine. The system comprises a rotator body, a reducer, a drive main motor. When the components are mounted, the drive main motor is connected with an input shaft of the reducer; the rotator body is connected with an output shaft of the reducer; and the drive main motor is connected with a variable-frequency speed regulation system. The utility model has the advantages that with the adoption of the variable-frequency speed regulation system, the variation of pressure difference arising from the cementation and the blockage of the wet-spraying machine and a spray head is utilized, and a programming controller is utilized to control a frequency converter to regulate the speed of the drive main motor, so that the real-time speed regulation of the feeding system of the concrete wet-spraying machine is achieved, the problem that the unadjustable speed and the frequent shut-down of a feeding system causes the damage to equipment in the prior art is effectively avoided, the service life of the equipment is prolonged, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of concrete construction machinery, especially relates to a kind of concrete spraying machine.
Background technology
Concrete spraying machine belongs to a kind of efficient concrete-spraying machine tool, and in underground construction, geotechnical engineering, fields such as municipal engineering are extensive use of.Its function is that the finished product concrete that concrete mixer stirs is entered from the concrete spraying machine hopper, evenly delivers to gas material mixing bunker by feed system.Utilize compressed air to be power, be delivered to the shower nozzle place along pipeline, at a relatively high speed ejection mixing the concrete mix that makes by a certain percentage.Currently used concrete spraying machine feed system, the rotating speed of its driving mechanism is fixed, so its rate of feeding is nonadjustable.When the wet shot machine is worked,, cause the bonding of concrete spraying machine pipeline and shower nozzle to stop up easily owing to concrete slump, workability etc. change.Adopt fixed feed system, when wet shot machine pipeline and the obstruction of shower nozzle generation bonding, have only first closing device, adopt mechanical method to remove the bonding obstruction then, will cause infringement like this, influence equipment life equipment.
The utility model content
The utility model has overcome shortcoming of the prior art; a kind of adjustable concrete spraying machine feed system is provided; when wet shot machine pipeline and the obstruction of shower nozzle generation bonding; can change instant its rate of feeding of reduction or stop feeding according to pressure reduction, utilize gases at high pressure to remove bonding under the non-stop-machine situation of realization equipment and stop up.
The technical solution of the utility model is: the adjustable feed system of a kind of concrete spraying machine, comprise rotor block, reducer, the main motor of driving, drive main motor and reducer input shaft connection, rotor block and reducer output shaft connection drive main motor and are connected with frequency conversion speed-adjusting system.
Described frequency conversion speed-adjusting system is linked in sequence by pressure difference transmitter, cyclelog and frequency converter and forms.
Compared with prior art, the utility model has the advantages that: owing to adopted frequency conversion speed-adjusting system, utilize the pressure reduction that wet shot machine pipeline and shower nozzle take place to cause when bonding is stopped up to change, by cyclelog frequency converter is controlled, to carry out speed governing to driving main motor, thereby realize the instant speed governing of concrete spraying machine feed system, avoided in the prior art the infringement that can not the frequent closing device of speed governing causes because of feed system effectively to equipment, thus prolonged equipment application life, reduced cost of production.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Disclosed all features in this manual, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this manual (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1, the adjustable feed system of a kind of concrete spraying machine comprises hopper 1, rotor block 2, reducer 3, drives main motor 4, frequency conversion speed-adjusting system 5, and frequency conversion speed-adjusting system is linked in sequence by pressure difference transmitter, cyclelog and frequency converter and forms.
During whole machine installation, reducer 3 is installed earlier on wet shot machine frame, is driven main motor 4 and reducer 3 power shaft connections, rotor block 2 and reducer 3 output shaft connections drive main motor 4 and are connected with frequency conversion speed-adjusting system 5.
Operating principle of the present utility model is: cause that after concrete spraying machine stops up pressure reduction changes, pressure difference transmitter just is transferred to pressure difference signal cyclelog (PLC or single-chip microcomputer), cyclelog outputs signal to frequency converter in view of the above, to driving main electric machine speed regulation, thereby realize adjustment to concrete spraying machine feed system rate of feeding.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
