[specific embodiment]
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Referring to Fig. 1, Fig. 2 and Fig. 3; A kind of emulsifying explosive loading trolley; Comprise big arm hydraulic control system of work and emulsified detonator loading system; Whole work system pressure can be set up through overflow valve 3, and the proportioning valve group is installed on the vehicle frame, and its effect mainly is hydraulic control or the big arm of manual operation work and hydraulic oil carried out assignment of traffic, pressure adjustment; Operating valve set 6 is installed on the work hanging basket, and its effect mainly is to utilize 5 actions of guide oil hydraulic control system proportioning valve group to reach the big arm of operation element.Therefore, when operating personnel need carry out the exercises operation to the big arm of working on the ground, can handle proportioning valve group 5 its action tanks of change and achieve the goal into and out of oil; When powder charge need be operated the big arm of working on operating personnel are working hanging basket, can two position three-way valve 4 be in shown position, utilize the operating valve set 6 hydraulic control proportioning valve groups 5 on the hanging basket to achieve the goal then.So the big arm hydraulic system of newly working has realized that operating personnel can operate big arm on the ground or on the work hanging basket.The action of big arm of working realizes through the operating cylinder that is installed on the vehicle frame respectively; Operating cylinder comprises hanging basket balancing cylinder 7, hanging basket pitching oil cylinder 8, big arm telescopic oil cylinder 9, arm is stretched oscillating oil cylinder 10 and big arm hoist cylinder 10 greatly; Above-mentioned operating cylinder passing ratio valve group 5, operation valve group 6 and overflow valve 3 respectively links with hydraulic gear pump 1 power, in the fuel tank 2 hydraulic oil is housed.
The powder charge system control sytsem mainly comprises hydraulic control system and electric control system, and as shown in Figures 2 and 3, hydraulic control system mainly is to control the powder charge system on the ground, and electric control system mainly is a control powder charge system on hanging basket.Medicinal cupping 14 bottom medicine outlets are cut transformation cooperate to adapt to the installation of helicoidal pump, Teat pipette 15 adopts helicoidal pump, and makes medicinal cupping 14 access covers, and the medicine in the medicinal cupping 14 is delivered in the pencil 20 through Teat pipette 15, and Teat pipette 21 provides power by Teat pipette oil motor 22; Simultaneously; Use the water tank 16 of thickness, open the ball valve 17 of water tank 16, filter through filter 18 then as a 250L of 5mm corrosion resistant plate making; Water is after filtering delivered to water in the water filling ring 19 through water pump 18 then; At last water is sent in the pencil 20, water pump 18 provides power by water pump oil motor 22, and the effect of water system is that lubricated pencil 20 inwalls are to reduce pumping resistance; During work, pour emulsion into medicinal cupping 14 after, start powder charge pump 15 and water pump 18 simultaneously, regulate the confluent of feed speed and the water pump 18 of Teat pipette 15, pencil 20 is inserted carry out charging work bottom the big gun holes then.In the powder charge process, if reasons such as pencil 20 obstructions cause the extruding of pipeline explosive, when pumping pressure strengthens, the safety valve film breaks, explosive flows out from safety valve, should shut down the processing great question this moment and could continue to use.After powder charge is accomplished in all big gun holes, must remove the remaining explosive in the pencil 20: let water pump 18 work independently, the water of discharging in the water filling ring 19 can be removed the remaining explosive in the pencil 20.Water pump oil motor 22 links with hydraulic system power with Teat pipette oil motor 21 passing ratio valve groups and operation valve group 6.When the powder charge system does not work, two position three-way valve 4 handles are placed top, main hydraulic oil flows back to main fuel tank 1; When needs powder charge system works, two position three-way valve 4 handles are placed the bottom, main hydraulic oil is supplied with work system (work big arm and powder charge system), and hydraulic oil arrives automatically controlled or manual proportioning valve group 5.During powder charge, depress the proportioning valve operating grip of control Teat pipette oil motor 21 and water pump oil motor 22 on the ground, start Teat pipette 14 and water pump 18 simultaneously, can carry out charging work this moment; On hanging basket, during powder charge, then control with the electrical system on the hanging basket; But the speed of powder charge speed passing ratio valve group 5 adjustment powder charge pumps 14 is set up.
The electric control system course of work is: during powder charge, manual change-over switch 23 is in top, depresses the powder charge switch on hanging basket; Whole charge controlling system gets electric, and the time relay 24 normally opened contacts are closed, hypotony switch 25 closures; Hypertonia switch 26 breaks off; This moment, automatically controlled or manual proportioning valve group 5 got electronic work, started Teat pipette 14 and water pump 18, can carry out powder charge.If in the powder charge process, the powder charge loine pressure is too high or too low, and this moment, hypertonia switch 26 or hypotony switch 25 will make start-up circuit break off (disconnect cause sees that the pressure alarm red light shows), closed Teat pipette 14 and stopped powder charge with water pump 18.As continue to carry out again after powder charge need be fixed a breakdown.
The installation of the prevention electrostatic system in the installation of equipment: powder charge process is because the friction of explosive and pencil 20 can produce static; Therefore; Something must be done to eliminates; Be the importing the earth that guarantees that all static on the vehicle can be smooth, safe; Must adopt the cable of good conductivity to connect to each pin joint on the vehicle, and in central hinged place with the conduction connecting line of a cable (cable trailer connects the corrosion resistant plate of a good conductivity), with the static that produces in the elimination powder charge process as vehicle and the earth; Simultaneously, must check and corrosion resistant plate is placed underground the connection situation of each pin joint cable before the powder charge, just can carry out powder charge.
