The working principle is as follows: the hoisting frame 1 is arranged on the roof in a house, when the height of the projector 8 needs to be adjusted, the operating rod 10 only needs to be rotated, the first bevel gear 12 is driven to rotate when the operating rod 10 is rotated, so that the second bevel gear 14 can be driven to rotate, the third bevel gear 21 can be driven to rotate in the same direction due to the fact that the second bevel gear 14 is connected with the third bevel gear 21 through the elastic pin 22, the third bevel gear 21 can drive the fourth bevel gear 18 to rotate, the stud 17 can be driven to rotate by the rotation of the fourth bevel gear 18, the stud 17 is fixed in the first bearing hole 16 through the second bearing 19, the stud 17 is connected with the hoisting frame 2 through threads, the stud 17 can only rotate but cannot move, so that the hoisting frame 2 can be driven to move up and down when the stud 17 rotates, so that the projector 8 can be driven to move up and down, and the up-and-down movement of the crane 2 can be realized only by rotating the operating lever 10 in the forward direction or the reverse direction during adjustment, and when the third bevel gear 21 and the second bevel gear 14 are installed, the inserting column 25 on the second bevel gear 14 is inserted into the connecting hole 23, then the elastic pin 22 is pressed in opposite directions to retract into the pin hole 24, then the connecting column 20 is inserted into the inserting column 25, when the elastic pin 22 reaches the position of the unlocking hole 26, the elastic pin is ejected into the unlocking hole 26 under the action of elasticity to realize the connection of the two and the connecting hole 23, when the crane is disassembled, the elastic pin 22 is also extruded in opposite directions to withdraw from the unlocking hole 26, the third bevel gear 21 can be extracted from the inserting column 25, when the projector 8 needs to be overhauled, the operating lever 10 is only required to rotate to drive the crane 2 to move downwards until the mounting rack 7 falls into the bracket 3, at this time, the crane 2 moves downwards to the lower end of the connection block 6 at the lowest point to contact with the upper end of the support plate 15, and at this time, the arc blocks 44 on the left fixing pin 32 and the right fixing pin 33 move downwards to the positions of the wheel carrier 29, because the distance between the two opposite arc blocks 44 is greater than the distance between the wheel carriers 29, the arc blocks 44 retract into the installation groove 31 under the extrusion of the wheel carrier 29, and the wheel 30 arranged on the wheel carrier 29 can slide relatively with the wheel 44 when the arc blocks 44 contact with the wheel carrier 29, so that the arc blocks 44 can smoothly retract into the installation groove 31, because the arc blocks 44 and the retraction pin 45 are integrated, the insertion pin 45 is driven to move downwards into the insertion hole 35, so that the insertion pin 45 is separated from the fixed groove 28, and because the arc blocks 44 are positioned between the wheel carriers 29, the insertion pin 45 is always kept in such a state, at the moment, the projector 8 can be taken down from the bracket 3, the maintenance efficiency is greatly improved conveniently and quickly, when the maintenance is finished and the mounting frame 7 is connected with the lifting frame 2, the mounting frame 7 is only required to be put into the bracket 3 to enable the lifting frame 2 to be positioned in the lower inserting hole 35 in the connecting groove 27 to align with the fixed groove 28, then the top cone connecting column 48 is pushed from the rear end of the lifting frame 2 to the inside of the lifting frame 2, the top cone 42 moves forwards, so that the top cone 42 can be inserted into the elliptical hole formed between the inclined plane stop blocks 40, then the two connecting pins 38 are pushed back until the cone block 43 on the top cone 42 passes over the inclined plane stop block 40 and is clamped on the plane behind the inclined plane stop block 40, so that the inclined plane stop block 40 plays a fixing role on the top cone 42 to enable the top cone 42 to retract insufficiently, the third spring 49 is in a compressed state, and the second spring 39 on the connecting pin 38 is also in a compressed state, at this time, the connecting pin 38 is enabled to extend out of the lower insertion hole 35 and enter the fixed groove 28 under the action of the top cone 42 to realize the connection between the crane 2 and the mounting bracket 7, at this time, the operating rod 10 can be rotated to drive the crane 2 to move upwards to drive the projector 8 to move upwards until the arc-shaped block 44 moves out of the space between the wheel carriers 29, so that the left fixing pin 32 and the right fixing pin 33 move backwards under the action of the first spring 36 to enable the arc-shaped block 44 to extend out of the upper insertion hole 34, the insertion pin 45 extends out of the lower insertion hole 35 and enters the fixed groove 28 to be connected with the mounting bracket 7, and the L-shaped frame 37 on the left fixing pin 32 in the transverse moving process is in contact with the cone-shaped block 43 to drive the top cone 42 to rotate so that the cone-shaped block 43 rotates to the position of the unlocking groove 41, then the cone-shaped block 43 passes through the unlocking groove 41 under the action of the third spring 49, and the top cone connecting pin 48 exits from the space between the connecting pins 38, in this way, the connecting pin 38 retracts into the through hole 46 again under the action of the second spring 39, so that switching between the connecting devices is realized, stable operation of the projector 8 is guaranteed, the third spring 49 is connected with the rotating ring 52 in order that the third spring 49 cannot influence rotation of the top cone connecting post 48, the rotating ring 52 can rotate freely and is inserted into the fixing ring 51, and therefore the third spring 49 cannot influence the top cone connecting post 48 when the top cone connecting post 48 rotates under the action of the L-shaped frame 37.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
