Abstract
The utility model discloses a locking device characterized in simple structure, convenient operation, and time- saving and energy-saving nature for the concrete pump outrigger. The locking device comprises a dead bolt and a lock tube. The dead bolt tube is arranged in one end in the lock tube, and an electromagnet is equipped on the other end of the lock tube. The core of the electromagnet is arranged in the lock tube and connected with the dead bolt through a jointing piece.
Description
Technical field
The utility model relates to concrete mixer, relates in particular to the locking system of concrete mixer supporting leg.
Background technology
At present, in the concrete mixer use,,, and be provided with locking system particularly in order to guarantee that the concrete mixer supporting leg can not show in motion in order to guarantee the stability of supporting leg in the process of moving.Known locking system as shown in Figure 1, a pump truck generally has this locking system of quadruplet, needs when the workman operates operating grip is placed open position one by one, operates the support leg valve switch then, the control supporting leg is flexible; After supporting leg was withdrawn fully, the workman needed again operating grip to be placed the lock position one by one.Adopt the shortcoming of this locking system, the firstth, the processing and fabricating complexity, the cost height all is non-standard configuration spare except that bolt; The secondth, this locking system is installed on concrete mixer, reserve lever operated space, take up room greatly, be not easy to pump truck and do the industry design; The 3rd is that the human-computer dialogue environment is bad, and the workman will walk two circles around pump truck and come switch lock in a work period of operation pump truck; The 4th is to have potential safety hazard, if workman's operating sequence is improper, forgets that opening locking system just operates support leg valve, serious operating accident will occur so.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of locking system of simple in structure, easy to operate, time saving and energy saving concrete mixer supporting leg is provided.
The locking system of concrete mixer supporting leg of the present utility model comprises dead bolt and lock tube, and lock bolt sleeve is located at the end in the lock tube, and the other end of described lock tube is equiped with electromagnet, and the electromagnetic core of electromagnet places in the lock tube, and links to each other with dead bolt by connector.
Described lock tube is provided with mount pad, and electromagnet is fixed on the mount pad.
Be arranged with the compression spring on the described electromagnetic core, the housing of compression spring one end and electromagnet joins, and set locating part joins on the other end and the electromagnetic core.
Described lock tube is provided with lubrication hole, is equiped with lubricated stopple on the lubrication hole.
Compared with prior art, advantage of the present utility model just is: removed the handle in the existing locking system, the switch by the magnet control lock when pump truck is done appearance and modeling and industrial design, does not need to reserve the operating space of handle; Reduced nonstandard accessory, processed simplyr, processing cost reduces, and production efficiency improves; The power that mount pad can be subjected to dead bolt is delivered on the pump truck by lock tube, plays the effect of protection electromagnet; Lock tube is provided with lubrication hole, is convenient to the locking system apply oil, guarantees that dead bolt can slide in lock tube flexibly; Improved the human-computer dialogue environment, can make locking system produce interlock when the workman controls supporting leg, the accident that locking system is not also opened when preventing the operation supporting leg and stretching out; The workman operates into need not walk about around pump truck each locking system that is installed on the pump truck is operated, as long as the circuit parallel connection of each locking system can be realized the unified control of each locking system.

The specific embodiment
As Fig. 2, Fig. 3, shown in Figure 4, the locking system of concrete mixer supporting leg of the present utility model, comprise dead bolt 1 and lock tube 2, dead bolt 1 is sheathed on the end in the lock tube 2, the other end that it is characterized in that described lock tube 2 is equiped with electromagnet 4, the electromagnetic core 41 of electromagnet 4 places in the lock tube 2, and links to each other with dead bolt 1 by connector 5.Locking system of the present utility model has removed the handle in the existing locking system, by the switch of electromagnet 4 control lock, does not need to reserve the operating space of handle, is convenient to pump truck is done appearance and modeling and industrial design; Reduced nonstandard accessory, processed simplyr, processing cost reduces, and production efficiency improves.Lock tube 2 is provided with mount pad 3; lock tube 2 is installed in by mount pad 3 on the pull bar 9 of fixedly capstan head seat of pump truck; electromagnet 4 is fixed on the mount pad 3, and the power that mount pad 3 can be subjected to dead bolt 1 is delivered on the pump truck by lock tube 2, plays the effect of protection electromagnet 4.Be arranged with compression spring 6 on the electromagnetic core 41, the housing 42 of compression spring 6 one ends and electromagnet 4 joins, and set locating part 43 joins on the other end and the electromagnetic core 41, and compression spring 6 can make locking system be in normally off.Lock tube 2 is provided with lubrication hole 21, is equiped with lubricated stopple 22 on the lubrication hole 21, is convenient to the locking system apply oil, guarantees that dead bolt 1 can slide in lock tube 2 flexibly.Electromagnet 4 communicates with a contactless contactor 7 by being electrically connected, and contactless contactor 7 is electrically connected with the signaling switch 8 of support leg valve, and support leg valve is used to control the flexible of supporting leg.
Operating principle: the locking system of concrete mixer supporting leg of the present utility model as shown in Figure 4 can be a plurality of parallel connections, and only needs the concrete mixer supporting leg is operated, and locking system will produce interlock.Press supporting leg and operate the signaling switch 8 of valve, it is electric that contactless contactor 7 is got, and it is closed that contactless contactor 7 gets electric back, and it is electric that electromagnet 4 is got, and locking system is opened, and in the retraction lock tube 2, the concrete mixer supporting leg stretches out or withdraws dead bolt 1 smoothly under electromagnet 4 acts on.The locking system of concrete mixer supporting leg of the present utility model has improved the human-computer dialogue environment, can make locking system produce interlock when the workman controls supporting leg, the accident that locking system is not also opened when preventing the operation supporting leg and stretching out; The workman operates into need not walk about around pump truck each locking system that is installed on the pump truck is operated, as long as the circuit parallel connection of each locking system can be realized the unified control of each locking system.
