As shown in fig. 1-3, the present embodiment provides an explosion-proof hoist, which includes a hoist drum 1, a driving assembly 2 for driving the hoist drum 1 to rotate, and a rope guiding device, wherein a plurality of rope grooves 12 are formed in the hoist drum 1 along a circumferential direction, the rope grooves 12 are arranged along an axial direction of the hoist drum 1, a steel wire rope 6 is wound in the rope grooves 12, and the rope guiding device is configured to arrange the steel wire rope 6 in the rope grooves 12 of the hoist drum 1 in order to prevent the steel wire rope 6 from being disordered. The both ends of electric hoist reel 1 are equipped with flange plate 3 respectively, and flange plate 3 rotates with the both ends of electric hoist reel 1 to be connected, and drive assembly 2 installs on one of them flange plate 3.
In this embodiment, as shown in fig. 1, the rope guiding device includes a guide rod 4, the guide rod 4 is disposed in parallel with the circumferential direction of the electric hoist drum 1, and two ends of the guide rod 4 are detachably connected to the flange plate 3 respectively. Specifically, threaded holes are formed in the end portions of two ends of the guide rod 4 respectively, and bolts penetrate through the flange plate 3 to be connected with the threaded holes. In other embodiments, the guide rod 4 may be connected to the flange plate 3 through other structures, which are not limited herein.
The guide rod 4 is sleeved with a rope guide wheel 5, and the rope guide wheel 5 can move along the axial direction of the guide rod 4. As shown in fig. 2, the rope guiding wheel 5 is provided with rope guiding grooves 51 for accommodating the steel wire rope 6 and protrusions 52 engaged with the rope grooves 12 on the electric hoist drum 1 at intervals along the circumferential direction, and a rope outlet 53 is provided between the rope guiding grooves 51 and the protrusions 52. Set up rope guide groove 51 and arch 52 on rope guide wheel 5, reduced the friction of rope guide with electric hoist reel 1 and wire rope 6, reduced the wearing and tearing to wire rope 6, improved the fail safe nature of explosion-proof calabash, prolonged the life of explosion-proof calabash.
When the rope guide wheel 5 is installed, the steel wire rope 6 adjacent to the rope outlet ring 11 on the electric hoist drum 1 is arranged in the rope guide groove 51, the bulge 52 is arranged in the rope groove 12 adjacent to the rope outlet ring 11, and the steel wire rope 6 on the rope outlet ring 11 penetrates out of the rope outlet 53 of the rope guide wheel 5. When the driving assembly 2 drives the electric hoist drum 1 to rotate clockwise, the heavy object descends, the steel wire rope 6 is wound out of the electric hoist drum 1, one side of the rope guide wheel 5 presses the steel wire rope 6 adjacent to the left side of the rope outlet ring 11, the other side of the rope guide wheel pushes the rope groove 12 adjacent to the right side of the rope outlet ring 11, the rope guide wheel 5 slides leftwards on the guide rod 4, and the steel wire rope 6 is sequentially wound out of a rope outlet 53 of the rope guide wheel 5; when the driving assembly 2 drives the electric hoist drum 1 to rotate anticlockwise, a heavy object rises, the steel wire rope 6 is wound into the electric hoist drum 1, one side of the rope guide wheel 5 presses the steel wire rope 6 adjacent to the left of the rope outlet ring 11, the other side of the rope guide wheel pushes against the rope groove 12 adjacent to the right of the rope outlet ring 11, the rope guide wheel 5 slides rightwards on the guide rod 4, the steel wire rope 6 is wound into the electric hoist drum 1 from the rope outlet 53 of the rope guide wheel 5 in a non-turbulent manner, therefore, the rope guide function is achieved, abrasion of the rope outlet 53 on the steel wire rope 6 is reduced, and the safety and reliability of the explosion-proof hoist are improved.
In this embodiment, the material of the rope guiding wheel 5 is copper, and the rope guiding wheel 5 made of copper has a self-lubricating effect, thereby facilitating the left and right sliding of the rope guiding wheel 5 on the guide rod 4. And the guide rod 4 can be used as a guide rod for the movement of the rope guide wheel 5 and a connecting rod for the lifting of the explosion-proof hoist.
In this embodiment, as shown in fig. 3, an image collector 7 is installed at the rope outlet 53 of the rope guide wheel 5, and the image collector 7 is used for collecting image information of the steel wire rope 6, so that the wear condition of the steel wire rope 6 can be monitored at any time, and the safety and the intelligence level of the explosion-proof hoist are improved.
Specifically, the side wall of the rope guide wheel 5 arranged at the rope outlet 53 is provided with a mounting groove 54, and the image collector 7 is mounted in the mounting groove 54, so that the rope guide of the rope guide wheel 5 is not affected, and the abrasion condition of the steel wire rope 6 can be effectively detected. In order to conveniently install the image collector 7, a threaded connector is arranged on the image collector 7, threads are arranged on the inner wall of the installation groove 54, and the image collector 7 is screwed in the installation groove 54.
Because explosion-proof calabash is applied to in the comparatively great environment of explosive gas or flammable dust density, in order to ensure that image collector 7 can effectively gather wire rope 6's image information, guarantee that image collector 7 does not receive environmental pollution, be equipped with the sealed cowling at the notch of mounting groove 54, the sealed cowling can be dismantled with the mounting groove 54 is sealed and be connected, and in order not to influence the smooth rope guide of rope guide wheel 5, the sealed cowling is installed back on rope guide wheel 5, the surface parallel and level of surface and rope guide wheel 5 of sealed cowling. The sealed cowling can with the inside wall threaded connection of mounting groove 54, easy to assemble and dismantle the sealed cowling, and played sealed effect simultaneously. The sealing cap may also be connected to the mounting groove 54 by other structures, which will not be described in detail herein.
In this embodiment, in order to increase the explosion-proof performance of the explosion-proof hoist and ensure the normal operation of the image collector 7, the definition of the collected image is high, and the sealing cover is made of toughened glass.
When the electric hoist winding drum 1 works, the rope guide wheel 5 rotates on the guide rod 4, in order to not influence the normal work of the rope guide wheel 5, the image collector 7 is a wireless image collector and is wirelessly connected with the controller of the explosion-proof hoist, and the installation structure of the image collector 7 is simplified on the premise of not influencing the normal work of the explosion-proof hoist.
Because the rope groove 12 on the electric hoist reel 1 is arranged along the circumference in an inclined manner, the inclined angle of the rope groove is a with the radial included angle of the electric hoist reel 1, the protrusion 52 on the rope guide wheel 5 needs to be embedded into the rope groove 12, in order to ensure that the rope guide wheel 5 can move on the guide rod 4 smoothly and in an unimpeded manner, and the reliability of the rope guide device is improved, as shown in fig. 4, the shaft hole 55 on the rope guide wheel 5 for the guide rod 4 to penetrate is inclined from one side of the protrusion 52 to one side of the rope guide groove 51 from top to bottom, and the included angle between the axis of the shaft hole 55 and the axis of the rope guide wheel 5 is also a.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
