Description

Technical Field

[0001] The present invention relates to the technical field of traction machines, and in particular to a traction machine for an explosion-proof elevator and a use method thereof. Background Art

[0002] Generally speaking, an elevator with explosion-proof performance is called an explosion-proof elevator. Since an explosion-proof elevator needs to be raised or lowered when in use, a traction machine is required to drive it. The traction machine is the power equipment of the elevator, also known as the elevator host. Its principle is that the motor drives the traction wheel to operate, and the extrusion force formed by the steel wire rope across the traction wheel on the traction wheel generates the static friction between the traction wheel and the traction steel wire rope to drive the traction steel wire rope to lift the car and the load;

[0003] However, when using, the traditional explosion-proof elevator traction machine is generally fixed in the working chamber by multiple bolts. After long-term use, the bolts are very easy to loosen, especially under the vibration generated when the motor is working. In addition, the brake configured for the traction machine is only used when the elevator stops. As a result, the explosion-proof elevator is prone to running too fast during operation, which increases the danger of using the explosion-proof elevator. For this reason, we propose a traction machine for explosion-proof elevators and a method for using the same. Summary of the invention

[0015] A method for using a traction machine for an explosion-proof elevator comprises the following steps:

[0016] S1: Installation: Screw the screws into the connection block, fix the mounting base in the compartment where the explosion-proof elevator is installed, slide the traction wheel to the right on the outer surface of the shaft, install the traction wheel on the shaft, rotate the limit plate on the outer surface of the shaft, screw the limit plate to the position that fits the traction wheel, and fix the traction wheel;

[0017] S2: Limiting: After the mounting seat and the traction wheel are installed, the staff activates the anti-dropping mechanism to move the limiting teeth to the position where they engage with the conical teeth, so that the limiting teeth simultaneously lock the conical teeth, thereby preventing the four conical teeth from rotating at the same time;

[0018] S3: Deceleration: When the anti-drop mechanism is running, the linkage mechanism drives the deceleration mechanism to move toward the traction wheel.

[0020] Compared with the prior art, the present invention provides a traction machine for an explosion-proof elevator and a method for using the same, which has the following beneficial effects:

[0021] 1. The traction machine for explosion-proof elevators and the use method thereof can limit the four screws at the same time through the mutual cooperation among the support block, the worm, the primary bevel gear plate, the secondary bevel gear plate, the threaded rod, the support frame, the moving block, the L-shaped bar, the limiting teeth and the conical teeth, so as to prevent the screws from loosening after long-term use, avoid the screws from falling off and causing the mounting seat to detach, thereby enhancing the safety of the traction machine when in use, and at the same time, it is more convenient when limiting.

[0022] 2. The traction machine for explosion-proof elevator and the method of using the same can properly brake the rotating shaft and reduce the running speed of the rotating shaft through the arrangement of the connecting head, rectangular frame, pull rod, pull block, arc-shaped brake pad and reset spring, so as to make the lifting and lowering of the explosion-proof elevator more stable and avoid the problem of the explosion-proof elevator running too fast during operation. At the same time, the limit plate can be supported to prevent the limit plate from falling off, thereby avoiding the traction wheel from being separated, and further enhancing the safety of the use thereof.

[0023] 3. The traction machine for explosion-proof elevators and the method of using the same can change the positions of the limit teeth and the speed reduction mechanism at the same time through the cooperation between the worm gear, the lead screw, the arc block and the threaded strip, and when driving, the staff only needs to turn the knob, which is very convenient.

[0024] 4. The traction machine for explosion-proof elevators and the method of using the same can drive the traction wheel to rotate together with the rotating shaft through the setting of the limit groove and the limit strip, and the traction wheel can be removed conveniently without the help of external tools through the cooperation between the limit plate, the anti-drop mechanism and the linkage mechanism.

5. The traction machine for explosion-proof elevator according to claim 1, characterized in that: The traction wheel (5) is provided with a limit groove (20), the outer surface of the rotating shaft (4) is fixed with a limit strip (21), and the limit strip (21) is slidably connected in the limit groove (20).

6. The method for using the traction machine for an explosion-proof elevator according to claim 1, characterized in that: The following steps are involved: S1: Installation: Screw the screw (8) into the connecting block (7), fix the mounting base (1) in the compartment where the explosion-proof elevator is installed, slide the traction sheave (5) to the right on the outer surface of the rotating shaft (4), install the traction sheave (5) on the rotating shaft (4), rotate the limit plate (6) on the outer surface of the rotating shaft (4), screw the limit plate (6) to a position where it fits the traction sheave (5), and fix the traction sheave (5); S2: Limiting: After the mounting seat (1) and the traction wheel (5) are installed, the staff activates the anti-dropping mechanism (9) to move the limiting tooth (909) to a position where it engages with the conical tooth (9010), so that the limiting tooth (909) simultaneously engages the conical tooth (9010), thereby preventing the four conical teeth (9010) from rotating. S3: deceleration: when the anti-falling mechanism (9) is in operation, the deceleration mechanism (13) is driven to move toward the traction wheel (5) through the linkage action of the linkage mechanism (11).
