Description

Technical Field

[0001] The present application relates to the technical field of on-site mixed blasting charge control systems, and in particular to a convenient charge controller for on-site mixed explosives. Background Art

[0002] The new technology of on-site mixed explosives has the advantages of economy, high efficiency and environmental protection. Internationally, highly mechanized underground on-site mixed explosives equipment has been maturely applied in underground mine tunnels, some tunnel excavation and other engineering fields. Some domestic underground tunnel and tunnel construction projects have gradually begun to use on-site mixed explosives and other charging equipment for charging and blasting operations.

[0003] Some small-scale charging equipment for on-site mixed explosives only uses an engineering vehicle chassis, auxiliary work platform and large mechanical trolley for charging operations. Usually, the vehicle's electronic control system and wireless handheld terminal are used in conjunction for charging operations. However, this type of charging operation requires a dedicated person to operate the electronic control system. On the other hand, in harsh underground environments such as humidity, noise and poor visibility, the electronic control system is easily affected by water, resulting in slow touch screen response. At the same time, communication between the electronic control system operator and the charging blaster on the wireless handheld terminal is not smooth, resulting in longer working time in dangerous environments and not conducive to safety control. Utility Model Content

[0004] In order to reduce the number of dedicated operators for the electronic control system, speed up the charging control operation, and improve the efficiency and safety of mixed explosive charging construction at underground engineering sites, the present application provides a convenient charging controller for on-site mixed explosive charging.

[0008] By adopting this technical solution, workers can control the charging operation of small-scale mixed explosive charging equipment on-site by wearing a fixed wristband and then controlling the controller host. Remote wireless control is an existing technology and can be configured according to actual conditions. This eliminates the need for one person to operate the electronic control system and another person to carry a wireless handheld terminal for notification.

[0012] The host status bar includes a diagram showing the connection with the control system of the small-sized charge equipment for mixing explosives on site, a diagram showing the power level of the controller host, and a time diagram;

[0013] The pumping pressure display unit displays the pump outlet pressure during the on-site explosive mixing and small-sized charging equipment feeding process;

[0014] The current charge quantity display unit displays the current on-site mixed explosive charge quantity of the blasthole;

[0015] The total charge quantity display unit displays the total on-site mixed explosive charge quantity during the process from the controller host is turned on to the shutdown;

[0016] The sensitizer display column displays the sensitizer material box number used by the sensitizer of the small-sized explosive charging equipment for mixing explosives on site at the current moment.

[0017] Through the above technical solution, when the on-site mixed explosives and small-sized charging equipment are delivering explosives, if the pumping pressure exceeds the threshold, the alarm display light will show a flashing red light and the alarm will sound, and the pumping work of the on-site mixed explosives and small-sized charging equipment will be automatically stopped.

[0018] Optionally, a sensitizer switching button is further provided on the controller host, and the sensitizer switching button is a multi-button structure.

[0019] By adopting the above technical solution, the number of sensitizer switching buttons is equal to the number of sensitizer boxes of the small-scale charging equipment for on-site mixed explosives. The sensitizer boxes are respectively loaded with sensitizers of different proportions to meet the requirements of on-site mixed explosives charging with different densities.

[0020] Optionally, the charge rotator includes a charge scale, a charge rotation button and a charge confirmation key;

[0021] The charge scale range is 0kg to 7.5kg, with the smallest scale unit being 0.25kg;

[0025] In summary, this application includes at least the following beneficial technical effects:

[0026] The fixed wrist strap is removable and attaches to the loader's forearm, making it easier for operators to operate. A sensitizer switch button switches sensitization to meet the requirements of on-site mixed explosive charging with different densities. A rotary button sets the charge amount and an OK button activates the small-scale charging equipment for on-site mixed explosive charging. Automatic alarms and automatic stoppage of pumping equipment for on-site mixed explosive charging when pumping pressure exceeds a threshold are provided. This replaces conventional terminal control systems, reduces the number of control system operators, and meets the requirements for rapid charging operations in harsh working conditions such as damp, noisy, and poorly visible environments in underground tunnels and roadways, further improving the efficiency and safety of underground engineering charging operations.
