Description

Technical Field

[0001] This utility model relates to the field of mechanical technology for electrified railway components, and in particular to an adjustable compensating pulley block correction device. Background Technology

[0002] The overhead contact system is a special type of power transmission line that supplies electricity to electric locomotives by zigzagging along the railway rails. The overhead contact system compensation device is a crucial piece of equipment for maintaining the tension required for the contact system, mainly composed of compensating pulleys, weights, and weight restraint frames. Currently, electrified railways in my country widely use compensating pulley blocks composed of fixed pulleys, movable pulleys, and compensating ropes. Different combinations of fixed and movable pulleys of varying specifications and quantities achieve the required tension for the contact system.

[0003] The compensating pulley block is installed between the anchor post and the non-working support line. It relies on the up-and-down movement of a weight suspended on the compensating rope to achieve the required tension in the contact wire. In actual operation, temperature changes cause the line to expand and contract, pulling the weight up and down. Due to installation process defects, accumulated errors in component fit, and the condition of the limiting frame, the fixed pulley of the compensating pulley block may become misaligned and not perpendicular to the ground. This causes repeated friction between the compensating rope and the sidewall of the fixed pulley groove, as well as the rim. When wear is severe, the pulley may develop a knife-edge rim, which can cut the compensating rope or break, causing the rope to dislodge from the groove. Ultimately, this results in insufficient tension in the contact wire, leading to an accident.

[0004] The distance between the two fixed plates of existing compensating pulley blocks varies depending on the manufacturer, and the pulley diameters also differ. Therefore, it is imperative to research and develop a correction device suitable for this working condition, which is also a key challenge in addressing the misalignment of compensating pulley blocks. To this end, we propose an adjustable compensating pulley block correction device. Utility Model Content

[0005] To address the problems and shortcomings of the components mentioned in the background art, this utility model provides an adjustable compensating pulley block correction device.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] An adjustable compensating pulley block correction device includes: two symmetrically arranged correction mechanisms and two rotationally symmetrically arranged base mechanisms. The correction mechanisms are S-shaped, with two U-shaped slots at their heads horizontally positioned and secured to the compensating pulley block fixing plate by tenon and mortise joints. Two rotationally symmetrical wing-shaped adjustment plates at their tails horizontally positioned are correspondingly connected to the base mechanisms. The base mechanisms are moved and adjusted so that the compensating rope is embedded in the correction pulley grooves provided inside them. A support assembly is provided between the two symmetrically arranged correction mechanisms.

[0008] In a further improvement, the correction mechanism includes a correction frame, an L-shaped clamping plate, a wing-shaped adjusting plate, a stop bolt, and an adjusting bolt, and the base mechanism includes a base bracket, correction pulleys, and bolt pins.

[0009] In a further improvement, the correction frame includes a horizontally arranged head section, a horizontally arranged tail section, and a vertically arranged connecting transition section. Two of the support components are located at the connecting transition section, and one is located at the tail section.

[0010] In a further improvement, the L-shaped card plate is welded to the inner side of the horizontal section of the head, forming the U-shaped card slot. One of the two U-shaped card slots is located at the left end of the horizontal section of the head with its opening facing downward, and the other is located at the right end of the horizontal section of the head with its opening facing upward.

[0011] In a further improvement, a wing-shaped adjustment plate is welded to the top of the left end of the horizontal section of the tail of one of the correction frames, and the outer side of the wing-shaped adjustment plate forms an angle of less than 180 degrees with the outer side of the horizontal section of the tail. A wing-shaped adjustment plate is welded to the bottom of the left end of the horizontal section of the tail of the other correction frame, and the two wing-shaped adjustment plates are rotationally symmetrical. Two parallel vertical slots are provided on the wing-shaped adjustment plates.

[0012] In a further improvement, after the correction frame rotates counterclockwise, the two U-shaped slots are secured to the compensation pulley block fixing plate in a tenon-and-mortise manner, and the stop bolt passes through the correction frame and contacts the outer frame of the compensation pulley block fixing plate.

[0013] In a further improvement, the diameter of the correction pulley is greater than half the distance between the fixed plates of the two compensation pulley groups, and the depth of its pulley groove is not less than half the depth of the groove of the fixed pulley.

[0014] In a further improvement, the bolt pin passes through the center of the correction pulley and is fixed inside the base bracket to form the base mechanism. The adjusting bolt passes through the slot on the wing-shaped adjusting plate and is connected to the base mechanism. The bottom of the base mechanism contacts the inner side of the wing-shaped adjusting plate, and the base mechanism moves relative to the vertical slot of the wing-shaped adjusting plate.

[0015] Through the above technical solution, the present invention has achieved the following beneficial effects:

[0016] This invention designs an adjustable compensating pulley block correction device, which solves the problems of the fixed pulley deviation of different specifications and models of compensating pulley blocks being unable to be adjusted and the compensating rope running path deviating from the side wall of the pulley groove, i.e., the wheel rim rubbing against it.

[0017] In the adjustable structure of the correction device provided by this utility model, the base mechanism that moves along the groove of the wing-shaped adjustment plate can adjust the distance between the shafts of the two correction pulleys and the distance between the compensation rope and the correction pulley. The left and right movement correction mechanism can adjust and solve the problem that the correction pulley and the compensation rope cannot be closely connected due to the different diameters of the fixed pulleys. It has a wide range of applications and fully meets the needs of the market.

[0018] The correction mechanism provided by this utility model is S-shaped, and its shape effectively transmits the force among the correction pulley, the compensating rope, and the fixed plate of the compensating pulley group.

[0019] The correction device provided by this utility model has two U-shaped slots with opposite openings, one facing up and the other facing down. This allows it to independently share the upward and downward forces on the correction device, resulting in strong stability. Its counterclockwise rotation secures it to the compensating pulley block fixing plate in a tenon-and-mortise manner, making it easy to assemble and disassemble.

[0020] The correction pulley provided by this utility model has a large diameter and a deep groove, allowing the compensation rope to be completely embedded in the groove, thus ensuring strong safety. Attached Figure Description

The base mechanism 2 is moved to adjust the compensating rope 6 so that it is embedded in the groove of the correction pulley 22 inside. A support component 3 is provided between the two symmetrically arranged correction mechanisms 1.

[0031] The correction mechanism 1 includes a correction frame 11, an L-shaped clamping plate 12, a wing-shaped adjusting plate 14, a stop bolt 15, and an adjusting bolt 16. The base mechanism 2 includes a base bracket 21, a correction pulley 22, and a bolt pin 23.

Three sets of support components 3 are arranged between the two correction mechanisms 1. Two support components 3 are arranged at the connecting transition section 113, and one is arranged at the tail section (112).

[0033] An L-shaped card plate 12 is welded to the inner side of the horizontal section 111 of the head, forming a U-shaped card groove 13.

The wing-shaped adjustment plate 14 is provided with two parallel vertical slots.

[0035] like Figure 3 As shown, during the installation process, after rotating the correction frame 11 counterclockwise, the two U-shaped slots 13 are secured to the compensating pulley group fixing plate 4 in a tenon-and-mortise manner. The position can be adjusted by moving left and right along the compensating pulley group fixing plate 4. Finally, the stop bolt 15 is used to pass through the correction frame 11 and contact and fix it to the outer frame of the compensating pulley group fixing plate 4.
