Safety locking device and method for explosive mixed loading vehicle

Abstract

The invention discloses a safety locking device and method for an explosive mixed loading vehicle, and belongs to the technical field of safety locking. The safety locking device comprises a lock shell and a spring bolt arranged in the lock shell, wherein one side of the spring bolt is provided with strip teeth; a driving cavity and a fixing seat are arranged outside the lock shell; a motor is arranged in the driving cavity; the output end of the motor is provided with a rotating shaft; a first bevel gear is arranged at one end of the rotating shaft; a second bevel gear matched with the firstbevel gear is arranged outside the first bevel gear; a rotating rod is arranged inside the second bevel gear, a circular gear matched with the strip teeth is arranged outside the rotating rod; an airbag is arranged on one side of the lock shell; an air pump is arranged in the fixing seat, one end of the air pump is connected with a connecting pipe; and the other end of the connecting pipe communicates with the air bag. According to the safety locking device and method for the explosive mixed loading vehicle, a side screw device is convenient to take and place, so that labor is saved, automatic locking of the side screw device is achieved, locking force is improved, and the problem that the side screw device loosens and falls off when the explosive mixed loading vehicle moves is solved.

Description

Technical field [0001] The invention relates to a safety locking device and method, in particular to a safety locking device and method of an explosive mixed loading vehicle, and belongs to the technical field of safety locking. Background technique [0002] The production of domestic explosives mostly still uses traditional preparation techniques. Professional equipment is used in the fixed production line to produce explosives of different specifications through the production process, and then go through many intermediate links such as storage and transportation in the warehouse of the production unit, storage in the warehouse of the business unit, and storage in the warehouse of the user unit. Finally, it is sent to the blasting site for blasting. The production process of the on-site mixed explosive is basically similar to that of commercial explosives, except that its manufacturing process is completed by two systems, the ground station and the on-site mixed truck. The devel...

Problems solved by technology

[0004] At present, the lock of the side screw device is usually locked through the lock case and the lock tongue. It is necessary to manually pull out the lock tongue and insert the lock tongue into the opening at the other end of the lock case, and engage with the locking mechanism. The structure is only suitable for side screw devices with a certain size, and manual operation is laborious and laborious. During the movement of the explosives mixing vehicle, it is often bumped for a long time, resulting in the loosening of the side screw device, and the opposite side screw device also has Wear consumption, reducing the service life of the side screw device
