Description

Technical Field

[0001] The utility model relates to a follow-up locking rope box of a current collector system, belonging to the field of current collector systems for rail or trolley buses. Background Art

[0002] At present, there are very few manufacturers of collector systems on the market, and the products equipped with rope boxes for collector systems are generally not easy to use and have a low service life. The rope material of most rope boxes is steel wire rope, which can easily cause wear to the vehicle body or the rope box shell during use, affecting the anti-corrosion performance of the vehicle body, and also has a great impact on its own service life. When ordinary rope boxes are in use, the ropes are stretched and scaled as the collector pole is raised and lowered, and the internal stress of the rope is always in a tense state, which causes great damage to the internal coil spring of the rope. Utility Model Content

[0003] The technical problem to be solved by the utility model is: how to solve the problem of easy wear and damage of the rope and the rope outlet parts at the head of the rope box, and provide a collector system with a follow-up locking rope box.

[0004] The technical solution of the utility model is specifically as follows:

[0005] A collector system follow-up locking rope box, comprising a rope box connected to the collector system, the rope box comprising a rope box housing, a shaft is arranged in the rope box housing, a coil spring is arranged outside the shaft, a rope is wound around the shaft, the rope is led out from a rope outlet component, the rope outlet component is arranged on the rope box housing, and the other end of the rope is connected to the collector rod through an insulating horn ring;

[0006] The inner wall of the rope box housing is provided with a bracket for placing a coil spring, the bracket is fixed to the rope box housing through a shaft, a spring nut is provided between the shaft and the rope box housing, a gear is provided on the bracket, and the gear and the locking disk constitute a ratchet mechanism.

[0007] The rope-discharging parts are made of ceramic parts.

[0008] The rope is made of polyurethane rope.

[0009] The rope box is fixed inside the rear door of the tram.

[0010] The beneficial effects of the utility model are as follows: the utility model sets a locking device as the collector rod is stretched, and the steel rope that is easy to cause wear to the vehicle body or the rope box shell is replaced by a rope made of wear-resistant material that is not easy to damage the vehicle body, thereby solving the problem of easy wear and damage of the rope and the rope outlet component of the rope box head.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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.

[0017] like Figure 1 As shown, a collector system follow-up locking rope box includes a rope box 4 connected to the collector system, and the rope box 4 is connected to the collector rod 2 through an insulating horn ring 7; the rope box 4 includes a rope box shell 8, and a shaft 11 is arranged in the rope box shell 8, and a coil spring 9 is arranged on the shaft 11, and a rope 15 is wound on the shaft 11, and the rope 15 is led out from a rope outlet component 10, and the rope outlet component 10 is arranged on the rope box shell 8, and the other end of the rope 15 is connected to the collector rod 2 through an insulating horn ring 7.

[0018] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the inner wall of the rope box housing 8 is provided with a bracket 14 for placing the coil spring 9, and the bracket 14 is fixed to the rope box housing 8 through the shaft 11. A spring nut 12 is provided between the shaft 11 and the rope box housing 8. A gear is provided on the bracket 14, and the gear and the locking disk 13 form a ratchet mechanism, thereby realizing the effect of one-way meshing and reverse locking. During assembly, the rope box housing 8 connects the coil spring 9, the spring nut 12, and the locking disk 13 together through the shaft 11, and the bracket 14 with the gear is connected to the rope box housing 8 separately through bolts. When the rope 15 is pulled, the coil spring 9 can drive the bearing to control the locking disk 13 to perform one-way self-locking. The principle of one-way self-locking is: the rope 15 is locked when it is pulled down and stopped, and the lock is released when it is pulled again, and it is firmly fixed.

[0019] Furthermore, the rope-out component 10 is a ceramic component, which is finely polished with aluminum nitride ceramics. After fine polishing, the corrosion resistance, insulation and hardness of aluminum nitride ceramics are higher than those of conventional iron parts, which can solve the problem of easy wear.

[0020] Furthermore, the rope 15 is made of polyurethane rope, which has less surface friction than traditional steel wire rope, is wear-resistant and has a long service life.

[0021] Therefore, the utility model solves the problems of follow-up locking, rope wear resistance and increased service life, and avoidance of the problem of easy wear of the rope and the rope box head.

[0022] In the collector system of the present invention, the output shaft of the cylinder 6 is connected to the collector rod 2 through the tension spring 5, and the rope box 4 of the collector system is connected to the collector rod 2 through the insulating horn ring 7. The rope box 4 is fixed in the rear door of the tram, and the rope 15 of the rope box 4 is retracted and released as the collector rod 2 works.

[0023] There are two working actions of the collector pole 2. When in non-working state, the cylinder 6 compresses the tension spring 5 through the push rod. After the collector pole 2 falls into place, the collector pole 2 is limited and locked by the tail hook device 3. When working, the tail hook device 3 opens, and the supporting push rod of the cylinder 6 pulls up the collector pole 2 with the tension spring 5, and connects it with the high-voltage cable through the collector head boot 1. In this complete process, the ropes of the rope box 4 move with the movement of the collector pole 2.

[0024] The insulating horn ring 7 is connected to the collector rod 2. When the collector rod 2 is working, the collector rod 2 pulls the insulating horn ring 7 to pull the rope 15, and the rope 15 is pulled out from the rope outlet component 10. When the rope 15 is pulled out, the coil spring 9 is tightened by force, and the locking disk 13 moves along with the polyurethane rope under the action of the tension of the rope 15. Figure 1 When the collector pole 2 reaches the designated position of the high-voltage cable, the cylinder 6 stops working, and the locking disc 13 and the ratchet of the bracket 14 are locked, thereby achieving the locking target. When the cylinder 6 moves, the coil spring 9 is pulled to drag the shaft 11 and the bracket 14 with gears, and the locking structure releases the locking relationship, that is, the polyurethane rope is released. This action from starting to locking and then to unlocking is a cycle process.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
