The specific implementation mode is as follows:

as shown in fig. 1 to 3, the following technical solutions are adopted in the present embodiment:

example (b):

a quick dismounting device for a spray nozzle in a drum of a coal mining machine comprises a connecting sleeve 1, a cross rod 2, clamping arms 3, a two-way screw 6, a slide rod 7 and a pendulum bob 10, wherein the cross rod 2 is symmetrically and fixedly connected to the outside of the connecting sleeve 1 and can support the two clamping arms 3, so that the stability of the equipment is improved, the clamping arms 3 are respectively and slidably connected to the outside of the two cross rods 2, the two-way screw 6 is in threaded connection between the two clamping arms 3, the distance between the two clamping arms 3 can be adjusted, so that nozzles of different specifications can be clamped, the application range of the equipment is favorably improved, the slide rod 7 is in threaded connection inside the connecting sleeve 1, the pendulum bob 10 is slidably connected to the outside of the slide rod 7, the nozzles can be quickly dismounted from the inside of the drum through the inertia force generated by the impact of the pendulum bob 10, so that the operation time is reduced, and the operation time of workers in risk areas can be shortened, meanwhile, the risk that workers accidentally injure the workers and iron chips are splashed to injure people can be avoided, and the safety factor is favorably improved.

Further, pinhole 4 has all been seted up to two horizontal poles 2 insides, and two pinhole 4 insides are all pegged graft and are had locating pin 5, can fix a position centre gripping arm 3 to prevent that centre gripping arm 3 from breaking away from.

Furthermore, slide bar 7 outside just is located pendulum 10 below cover and has been connect down baffle 8, can restrict the gliding scope of pendulum 10, and slide bar 7's top fixedly connected with overhead gage 9 can use with pendulum 10 cooperation to produce inertial force, can be quick pull down the nozzle.

Furthermore, handles 11 are symmetrically and fixedly connected to the outer portions of the pendulums 10, so that the pendulums 10 can be operated by a worker conveniently, and are driven to slide on the sliding rods 7 in a reciprocating mode.

Specifically, when the device is used, a worker firstly installs the sliding rod 7 on the connecting sleeve 1, so as to assemble the device, then rotates the two-way screw 6, at the same time, two clamping arms 3 outside the two-way screw 6 move outside the two-way screw, at the same time, the clamping arms 3 slide on the cross rod 2, so as to adjust the distance between the two clamping arms 3, ensure that the distance between the two clamping arms 3 is larger than the diameter of the nozzle, then moves the clamping arms 3 to both sides of the nozzle, and rotates the two-way screw 6 again, so as to enable the two clamping arms 3 to clamp the nozzle, at the moment, the worker drives the pendulum bob 10 to slide on the sliding rod 7 in a reciprocating manner through the handle 11, enables the pendulum bob 10 to impact the upper baffle plate 9, and when the pendulum bob 10 is driven to move, the worker needs to avoid the contact between the pendulum bob 10 and the lower baffle plate 8, and through inertia generated by the impact between the pendulum bob 10 and the upper baffle plate 9, the nozzle can be quickly detached from the interior of the drum.
