Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.
[0020] Please refer to Figures 1-4 , the overhead crane end beam safety protection device, including the beam 1, the top of the beam 1 is fixedly connected with the track 2, the outer wall of the beam 1 is provided with a walking area 3, the inner cavity of the beam 1 is provided with a movable area 4, the outer wall of the beam 1 is fixedly installed with a lighting lamp 5, the outer wall of the beam 1 is fixedly connected with a railing 6, the outer wall of the beam 1 is fixedly connected with a side rod 7, a steel wire rope 8 is sleeved inside the side rod 7, the outer wall of the beam 1 is fixedly connected with an intermediate rod 9, an additional installation box 10 is installed on the outer wall of the intermediate rod 9, a movable groove 11 is opened inside the additional installation box 10, a return spring 12 is arranged inside the movable groove 11, the top of the return spring 12 is connected with a clamping joint 13, an extraction groove 15 is fixedly connected to the outer wall of the clamping joint 13, and an extraction groove 15 is opened inside the intermediate rod 9. Through the mutual cooperation of the manual rod 14, the clamping joint 13, the extraction groove 15 and the steel wire rope 8 on the device, when the manual rod 14 on the device drives the clamping joint 13 downward under manual control, the downward drive of the clamping joint 13 creates an opening gap for the extraction groove 15, so that the steel wire rope 8 on the device can temporarily withdraw from the inner cavity of the intermediate rod 9, and further the extraction groove 15 is not confined in the inner cavity of the intermediate rod 9.
[0021] In a preferred embodiment, the number of the tracks 2 is two, and the two tracks 2 are symmetrically arranged on both sides of the beam 1. Through the two tracks 2 on the device, the tracks 2 on the device are established at symmetrical positions on both sides of the top of the beam 1, and the overhead crane is lapped on the top of the track 2, so that the crane moves along the track 2.
[0022] In a preferred embodiment, the number of the lighting lamps 5 is several, and the opening directions of the several lighting lamps 5 face downward. Through the several lighting lamps 5 on the device, the device is at a relatively high position in the use scenario, and the lighting lamps 5 are used to illuminate the lower part, so that the field of vision directly below the device is bright.
[0023] In a preferred embodiment, the side rod 7 and the intermediate rod 9 have the same structure, and the side rod 7 is installed at the front and rear ends of the device. Through the same structure of the side rod 7 and the intermediate rod 9 on the device, the side rod 7 on the device is installed at the front and rear ends of the beam 1, so that when the steel wire rope 8 on the device passes through the side rod 7 and the intermediate rod 9, the intermediate rod 9 is used for supporting from the middle section.
[0024] In a preferred embodiment, the bottom of the reset spring 12 is connected to the inner wall of the installation box 10, and the top of the reset spring 12 is connected to the bottom of the clamping joint 13. Since the bottom of the reset spring 12 on the device is connected to the inner wall of the installation box 10, when the clamping joint 13 on the device moves downward, it will compress the reset spring 12, so that the reset spring 12 contracts downward along the inner cavity of the installation box 10.
[0025] In a preferred embodiment, the bottom of the clamping joint 13 extends into the inner cavity of the movable slot 11, and the manual rod 14 is connected to the extended part of the bottom of the clamping joint 13. Since the bottom of the clamping joint 13 on the device extends into the inner cavity of the movable slot 11, the part of the clamping joint 13 on the device extending into the inner cavity of the installation box 10 moves up and down along the inner wall of the movable slot 11, and the manual rod 14 is connected to the outer wall of the bottom of the clamping joint 13. Therefore, when the manual rod 14 on the device is manually controlled, the manual rod 14 is used to press the clamping joint 13 downward.
[0026] Working principle: First, through the mutual cooperation of the steel wire rope 8, the side rods 7, and the middle rod 9 on the device, when the device needs to be repaired or overhauled, maintenance personnel can actively hang the safety rope on the outer wall of the steel wire rope 8, and use the side rods 7 at the front and rear ends and the middle rod 9 in the middle to support the steel wire rope 8, so that the maintenance personnel can work safely on the overhead crane relying on the safety rope. Then, through the mutual cooperation of the manual rod 14, the clamping joint 13, the extraction slot 15, and the steel wire rope 8 on the device, when the manual rod 14 on the device drives the clamping joint 13 downward under manual control, the downward drive of the clamping joint 13 creates an opening gap for the extraction slot 15, so that the steel wire rope 8 on the device can temporarily withdraw from the inner cavity of the middle rod 9, and further the extraction slot 15 is not confined in the inner cavity of the middle rod 9. At the same time, it enables the maintenance personnel not to need to release the buckle on the safety rope and hang it again, but only to move the buckle on the safety rope to the steel wire rope 8 on the other side.
[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
