Abstract
The utility model relates to an emergency treatment device of a concrete pump truck. The emergency treatment device mainly comprises manual operated switches RS1 and pumping selection switches TS1. Automatic and manual selection switches TS1 are respectively in series connection between a programmable logic controller (PLC) and valves of push cylinders (DT3 and DT4) and oscillating cylinders (DT1 and DT2) of different concrete pump truck pumping systems; and are connected with a power source through one manual operated switch RS1 respectively. With the emergency treatment device, loss caused by fault of equipment can be lowered and more time can be gained for maintenance when in difficulty in fault detection or in delaying of maintenance.
Description
Technical field
The utility model belongs to the automobile-used concrete mixer career field of concrete pump, relates to a kind of pumper operation device, is specifically related to a kind of concrete mixer emergency treatment device.
Background technology
At present, concrete mixer is widely applied at the construction field (site).In the pumping of concrete process; often can be owing to the electrical system reason causes normally pumping work of pump truck; yet can not provide timely again relatively difficulty of maintenance or fault detect; the concrete construction that the concrete of equipment the inside can not be disposed timely or pour into a mould can not be interrupted again, thereby brings larger loss.
Summary of the invention
The purpose of this utility model is that fault detect has any problem or keep in repair in the situation about can not in time carry out, and a kind of concrete mixer emergency treatment device is provided, and this device can emergency operation, in order to avoid result in greater loss, also creates the more time for maintenance.
The technical solution of the utility model is:
The concrete mixer emergency treatment device, mainly formed by manual operation switch RS1, pumping selector switch TS1, it is characterized in that: connect respectively into auto-manual selector switch TS1 between the valve that pushes away cylinder (DT3, DT4) and oscillating oil cylinder (DT1, DT2) of original programmable logic controller (PLC) PLC and each concrete pump truck pumping system of control, each auto-manual selector switch TS1 links to each other with power supply by a manual switch RS1 that turns round respectively.Pumping selector switch TS1 has manually, automatically, stop third gear, manual operation switch RS1 has positive pump, anti-pump second gear.
Application process is as follows: pumping selector switch TS1 is got to manually, this moment overflow valve or similar functions valve get electric, if need positive pump then according to the piston manual operation switch RS1 that turns clockwise successively that whether puts in place.Be rotated counterclockwise successively manual operation switch RS1 if need anti-pump then whether put in place according to piston.By clockwise and be rotated counterclockwise manual operation switch RS1 control the concrete pump truck pumping system push away cylinder DT3, DT4 and oscillating oil cylinder DT1, DT2 must be electric, thereby realize normal pump action.
The advantage of this device is to realize emergent operation with several switches seldom, can reduce or avoid because the unnecessary loss that plant issue causes.
Description of drawings
Fig. 1 is cylinder action figure during the utility model uses.
Fig. 2 is connection diagram of the present utility model.
The specific embodiment
The utility model will be further described by reference to the accompanying drawings.
As shown in Figure 2, concrete mixer emergency treatment device of the present utility model, mainly formed by manual operation switch RS1, pumping selector switch TS1, connect respectively into auto-manual selector switch TS1 between the valve that pushes away cylinder (DT3, DT4) and oscillating oil cylinder (DT1, DT2) of original programmable logic controller (PLC) PLC and each concrete pump truck pumping system of control, each auto-manual selector switch TS1 links to each other with power supply by a manual switch RS1 that turns round respectively.Pumping selector switch TS1 has manually, automatically, stop third gear, manual operation switch RS1 has positive pump, anti-pump second gear.
As shown in Figure 1, in the time of using emergency set, step is as follows:
At first pumping selector switch TS1 is switched to manual state, this moment is after engine speed reaches working speed, the main oil pump discharge capacity is adjusted to suitable size, rotary manual running switch RS1, oscillating oil cylinder DT1 get that the S valve is positioned at 1 place, position when electric, and the S valve swings to opposite side when electric when another oscillating oil cylinder DT2 gets, pushing away cylinder DT3 gets and carries when electric cylinder 1 to stretch out forward, carry cylinder 2 to shrink, another pushes away cylinder and carries cylinder 1 to after-contraction when DT4 gets when electric, and conveying cylinder 2 stretches out forward.
As shown in Figure 2, during rotary manual running switch RS1, specifically move as follows:
When manual operation switch RS1 is one grade at initial position, oscillating oil cylinder DT1 and push away cylinder DT3 and get electric, when clockwise choosing turns, push away the action of cylinder (DT3, DT4) and oscillating oil cylinder (DT1, DT2) the same side, for positive pump state, when being rotated counterclockwise, push away cylinder (DT3, DT4) and oscillating oil cylinder (DT1, DT2) crossed work, be anti-pump state, thereby realized the control to pumping system.
