The invention discloses a locking device for an automobile body rotary welding clamp, which is mounted at the bottom of the clamp, and comprises a pedal arm, a locking mechanism, and a reset mechanism, wherein one end of the pedal arm is hinged with a BASE plate of the clamp; the other end of the pedal arm is used for stepping on; the locking mechanism is connected with the BASE plate of the clamp, and comprises a locking rod; the locking rod can move up and down; the upper end of the locking rod is inserted into a lock hole formed in a clamp swing table; the lower end of the locking rod is connected with the pedal arm; the pedal arm drives the locking rod to move; the reset mechanism is connected between the BASE plate of the clamp and the pedal arm, and used for resetting the pedal. Compared with the prior art, the locking device has the advantages that an operator can step on the pedal arm, so that the pedal arm drives the locking mechanism to conduct corresponding actions and further unlock and lock the clamp. Therefore, the locking device is convenient to operate; the operator is not required to stoop during operation, which reduces labor intensity and working hours, and eliminates safety hazards in the operation process.

The invention discloses an automatic painting robot for shipbuilding painting, which includes a painting movement mechanism, a PLC and a spray gun; the painting movement mechanism includes a left and right movement mechanism, a front and rear movement mechanism and a rotation movement mechanism; The first motor, the first motor drives the slide block to move left and right, the spray gun is fixed on the slide block, the first shell is provided with a distance sensor; The internal movement of the motor moves back and forth; the rotary motion mechanism includes a support plate, a third motor and a fixed gear, the left and right motion mechanism and the support plate are connected to the inner shell through a bearing, the third motor drives the left and right motion mechanism to rotate around the bearing, the distance measuring sensor, the first motor , the second motor and the third motor are respectively electrically connected to the PLC. The invention improves work efficiency, saves labor cost, shortens construction period, has good uniformity of paint coating, and improves the quality of paint coating.

The invention relates to a roof support process under a coal mine, in particular to fully mechanized mining face mining stopping support method. The problems that an existing fully mechanized mining face is high in mining stopping I-shaped steel support cost, large in labor intensity of workers and long in mining stopping support construction period, and top plate local breaking is prone to occurring are solved. According to the fully mechanized mining face mining stopping support method, anchor cables, anchor rods, metal nets, steel belts and combined anchor cable groups are adopted for combining support, the self-bearing capability of a bracket is matched, and mining stopping support is conducted; and the working face is divided into a frame dismantling channel, a bracket and mining stopping support combined support area and a natural caving area according to purposes after mining stopping to conduct top plate management during mining stopping, local support strengthening is conducted in a targeted mode, and I-shaped steel is replaced by the combined anchor cable groups, so that support is more timely, and the top plate separate layer phenomenon is avoided. Compared with existingmining stopping support, the material cost and manual consumption are greatly reduced, and the safety risk in construction is also reduced. The mining stopping support working period is shortened from 25 working days to 13 working days.

The invention discloses an auxiliary device for installing a LNG ship insulating box and a using method of the auxiliary device. A plurality of rows of parallel T-shaped clamping grooves are formed inthe side wall of an insulating box panel. The auxiliary device comprises a detachable hand guided pull rod, embedded type movable clamping tongues and a lock nut, wherein at least two through holes are formed in the detachable hand guided pull rod, and the distance of the through holes is equal to the distance between any two rows of the clamping grooves; and the embedded type movable clamping tongues comprise bottoms of a T-shaped cross section matched with the clamping grooves and protruding studs connected to the bottom and extending out of the clamping grooves, the embedded type movable clamping tongues are slidably arranged in the clamping grooves, and the protruding studs penetrate through the through holes and protrude out of the through holes. The auxiliary device for installing the LNG ship insulating box has the beneficial effects that the installation efficiency of the insulating box can be improved, and the production cost, the field labor intensity and potential safety hazards are effectively reduced.

The invention provides a double-surface core supporting plate. The double-surface core supporting plate disclosed by the invention comprises a body, wherein the body is provided with two working planes which are oppositely arranged, the two working planes are mutually parallel, and the working planes are both used as core supporting surfaces for bearing sand cores. The double-surface core supporting plate provided by the invention does not need to be turned over in the use process, so that the production efficiency is high, and the safety is better.
