Description

Technical Field

[0001] The utility model relates to the technical field of anti-derailing devices, in particular to an anti-derailment device for the wire rope of a fixed pulley of a bridge crane. Background Technique

[0002] Bridge cranes are generally lifting equipment that spans over workshops, warehouses, and yards for material lifting. They are also one of the common lifting equipment. The fixed pulley is one of the important components of the bridge crane, which guides the movement of the rope and plays a role in guiding and balancing. In order to avoid the phenomenon of wire rope derailment between the fixed pulley and the wire rope, generally, an anti-derailment device for the wire rope of the fixed pulley is set on the bridge crane. However, the existing anti-derailment devices for the wire rope of the fixed pulley still have some disadvantages, such as poor limit clamping effect. Generally, the anti-derailment treatment of the wire rope is carried out through a single surface, and such a method is still prone to the phenomenon of wire rope derailment. At the same time, the anti-derailment part of the wire rope cannot be monitored and viewed in real time during daily work. Therefore, we propose an anti-derailment device for the wire rope of the fixed pulley of the bridge crane. Content of the Utility Model

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1:

[0020] See also Figures 1-3, the present utility model provides a technical solution: a device for preventing the steel wire rope from slipping out of the fixed pulley of a bridge crane, which includes a pulley fixing plate 1. In the middle of the rear end face of the pulley fixing plate 1, there is a pulley shaft 2. At the rear end face of the pulley shaft 2, there is a fixed pulley, and a steel wire rope 3 is arranged on the fixed pulley. The above contents are all common prior arts in the field, so no detailed description will be given in the text. On the middle parts of the left and right sides of the front end face of the pulley fixing plate 1, there are fixing plates 4 respectively. At the top and bottom of one end of the front end face of the fixing plate 4 close to the pulley fixing plate 1, there are bolts 5 respectively, and the fixing plate 4 and the pulley fixing plate 1 are fixedly connected through the bolts 5. The fixing plate 4 can be stably installed on the front end face of the pulley fixing plate 1 through the bolts 5. At the top and bottom of the front end face of the fixing plate 4, there are horizontal reinforcing ribs 6 respectively. From left to right in the middle of the front end face of the fixing plate 4, there are vertical reinforcing ribs 7 in sequence. By setting the horizontal reinforcing ribs 6 and the vertical reinforcing ribs 7, the structural strength of the fixing plate 4 can be effectively increased, making it not easy to deform and break. At the ends of the rear end face of the fixing plate 4 far from the pulley fixing plate 1, there are mounting plates 8 respectively. At the ends of the inner sides of the mounting plates 8 far from the fixing plate 4, there are electric telescopic rods 10 respectively. At the ends of the electric telescopic rods 10 far from the mounting plates 8, there are end plates 13 respectively. When the electric telescopic rods 10 expand and contract, they can drive the end plates 13 to move left and right. At the front and rear end faces of the ends of the end plates 13 far from the electric telescopic rods 10, there are side plates 14 respectively. At the ends of the opposite faces of the side plates 14 close to the end plates 13, there are anti-slip roller shafts 15 respectively, and anti-slip rollers 16 matching the steel wire rope 3 are arranged through the anti-slip roller shafts 15. In the middle of the opposite faces of the side plates 14, there are limiting rods 17 respectively. At the ends of the limiting rods 17 far from the side plates 14, there are ball grooves 18 respectively, and balls 19 are arranged in the ball grooves 18. When the end plates 13 move left and right, they will drive the anti-slip rollers 16 to approach the steel wire rope 3 through the side plates 14 until they fit against the outer wall of the steel wire rope 3. And the balls 19 arranged on the limiting rods 17 will also fit against the front and rear end faces of the side of the steel wire rope 3. In this way, it can cooperate with the anti-slip rollers 16 to achieve the effect of triangular positioning and clamping, thus avoiding the phenomenon of the steel wire rope slipping out of the groove. At the top sides of the middle parts of the ends of the end plates 13 far from the electric telescopic rods 10, there are mounting plates 1-22 respectively. An external camera 23 is installed on the mounting plates 1-22. The camera 23 can monitor the position of the steel wire rope 3 to prevent it from slipping out of the groove in real time. At the top of the front and rear end faces of the ends of the end plates 13 far from the electric telescopic rods 10, there are lighting lamps 24 respectively. The lighting lamps 24 can provide light for the work of the camera 23.

[0021] Among them, preferably, a connecting plate 11 is arranged between the electric telescopic rod 10 and the end plate 13. The connecting plate 11 is fixedly connected with the electric telescopic rod 10. Fixed bolts 12 are arranged between the outer periphery of the connecting plate 11 and the end plate 13. Such a setting can increase the connection stability between the electric telescopic rod 10 and the end plate 13, avoiding the phenomenon of loosening and swinging.

[0022] Preferably, small reinforcing plates 20 are arranged around one end of the limiting rod 17 close to the side panel 14, and external thread connection blocks 21 are arranged at one end of the limiting rod 17 close to the side panel 14. Threaded holes matching the external thread connection blocks 21 are arranged at corresponding positions on the inner side of the side panel 14. The limiting rod 17 can be conveniently disassembled and assembled through the cooperation of the external thread connection block 21 and the threaded hole, so that when the ball 19 falls off or is damaged, it can be replaced in time.

[0023] Preferably, reinforcing plates 9 are arranged at one end of the inner side of the mounting plate 8 close to the fixing plate 4. The stability of the connection between the mounting plate 8 and the fixing plate 4 can be increased through the arranged reinforcing plates 9. Reinforcing plates 25 are arranged between the end plate 13 and the side panel 14. The stability of the connection between the end plate 13 and the side panel 14 can be increased through the arranged reinforcing plates 25.

[0024] Embodiment 2:

[0025] Refer to Figures 1-3 , the difference between this embodiment and the first embodiment is that the included angle between the fixing plate 4 and the mounting plate 8 on the same side is set to 90 degrees, and the fixing plate 4 and the mounting plate 8 on the same side are of an integrally formed structure. The integrally formed structure has high strength and is not easy to deform, which can effectively extend the service life; both the top and bottom of the vertical reinforcing rib 7 are fixedly welded to the horizontal reinforcing rib 6, and the length of the horizontal reinforcing rib 6 from left to right is greater than half of the length of the fixing plate 4 from left to right, so as to increase the reinforcement effect and strengthen the strength of the fixing plate 4; the side panels 14 on the same side are arranged in parallel, and the included angles between the side panels 14 and the end plate 13 are all set to 90 degrees. Such a setting can increase the stability of the connection between the side panels 14 and the end plate 13 and avoid the phenomenon of connection deviation with the fixed pulley.
