[specific embodiment]
The present invention is further described below in conjunction with drawings and Examples.
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 by overflow valve 3, 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, two position three-way valve 4 can 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 by 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 by Teat pipette 15, and Teat pipette 21 provides power by Teat pipette oil motor 22; Simultaneously, make the water tank 16 of a 250L for the 5mm corrosion resistant plate of thickness, open the ball valve 17 of water tank 16, filter by filter 18 then, water is after filtering delivered to water in the water filling ring 19 by water pump 18 then, water is sent in the pencil 20 at last, 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 the feed speed and the water pump 18 of Teat pipette 15, then pencil 20 is inserted bottom, big gun holes and carries out charging work.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 finished in all big gun holes, must remove the remaining explosive in the pencil 20: allow 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 and Teat pipette oil motor 21 passing ratio valve groups and operation valve group 6 link with hydraulic system power.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 that powder charge speed passing ratio valve group 5 is adjusted powder charge pump 14 is set up.
The electric control system course of work is: on hanging basket during powder charge, manual change-over switch 23 is in top, depress the powder charge switch, whole powder charge control system gets electric, the time relay 24 normally opened contact closures, hypotony switch 25 closures, hypertonia switch 26 disconnects, 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 disconnect (disconnect cause sees that the pressure alarm red light shows), closes Teat pipette 14 and water pump 18 stops powder charge.As continue to carry out again after powder charge need be fixed a breakdown.
The installation of the pre-anti-static system in the installation of equipment: powder charge process is because the friction of explosive and pencil 20 can produce static, therefore, must take measures to be eliminated, 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 the cable corrosion resistant plate of a good conductivity (cable trailer connect), 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.
