Description

Technical Field

[0001] This invention relates to the field of special equipment technology, and in particular to a pulley release device and release method with interlocking protection. Background Technology

[0002] Non-powered ziplines have become a common attraction in amusement parks. However, with their increasing popularity, the number of safety accidents associated with ziplines has also increased. A large proportion of these accidents are due to improper operation by staff, such as releasing the zipline prematurely before the arrival station is ready, leading to accidents.

[0003] To address this issue, the arrival station operator must confirm that the passenger has safely disembarked before pressing the release button. Only after the departure station operator receives the release signal can the release interlocking device be activated to allow the passenger to depart.

[0004] Currently, there are two main methods for releasing trolleys: one uses a simple small hook fixed to a steel cable at the departure station and reset by gravity or a spring; the other uses a safety lock to prevent the trolley from sliding down. Both methods require manual operation by staff at the departure station. The drawback is that if passengers at the departure station are not properly seated or the arrival station is not ready, an accident could easily occur if staff negligently release the trolley, posing a significant safety hazard. Therefore, there is an urgent need to develop a trolley release device with standardized operating procedures, allowing staff at the arrival station to participate in control, and featuring interlocking protection. This would significantly improve the safety of passengers riding the trolley. Summary of the Invention

[0005] The main objective of this invention is to overcome the shortcomings of the prior art and provide a pulley release device and release method with interlocking protection.

[0006] The technical solution adopted by the present invention to achieve its technical objective is: a pulley release device with interlocking protection, the pulley release device including a release hook and a mounting base;

[0007] The mounting base has two symmetrical parts, both of which are fixedly connected to the load-bearing cable by extended U-shaped screws, clamping washers and nuts; the extended U-shaped screws and matching clamping washers can be adjusted in position and number during installation as needed;

[0008] A base reinforcement beam and a motor mounting frame are fixedly connected to the middle of the top of the mounting base. The base reinforcement beam and the motor mounting frame are simultaneously fixedly connected to the top of the two mounting bases. The base reinforcement beam is used to increase the stability of the connection between the motor mounting frame and the mounting base, thereby increasing safety.

[0009] An electric push rod is installed inside the motor mounting frame. The electric push rod is fixedly connected to the motor mounting frame in an inverted position, and a release hook connecting beam is provided at one end. The release hook connecting beam is lowered and raised by the extension and retraction of the electric push rod.

[0010] Two release hooks are provided symmetrically and are rotatably mounted on the two mounting bases. One end of each release hook is fixedly connected to the release hook connecting beam. The release hook is raised and lowered by the release hook connecting beam. When the electric push rod extends and lowers the release hook connecting beam, the release hook is raised, and vice versa.

[0011] Preferably, the release hook includes two pairs of supports, a pair of rotating shafts, a pair of release hook levers, a pair of blocking blocks, a pair of upper limit bolts, and a pair of lower limit bolts;

[0012] The lever is rotatably connected to the support via the pivot. The short arm of the release hook lever is fixedly connected to the release hook connecting beam, and the blocking block, upper limit bolt, and lower limit bolt are fixedly installed at the end of its long arm. The blocking block is restricted by the limit bolt and can move within a certain range, which can block the exiting trolley but not the entering trolley.

[0013] Preferably, the release hook connecting beam is fixedly installed at one end of the electric push rod by a pair of male and female universal joint ball joints. By adjusting the setting of the universal joint ball joints, the range of motion of the release hook can be changed according to their tightness.

[0014] Preferably, the electric push rod is electrically connected to the motor direct control box, and the motor direct control box controls the extension and retraction of the electric push rod.

[0015] Preferably, the trolley release device further includes a departure station remote control box and an arrival station remote control box. The departure station remote control box and the arrival station remote control box communicate bidirectionally, and the departure station remote control box communicates unidirectionally with the motor direct control box. The departure station remote control box can only control the motor direct control box to raise the release hook and release the trolley after sending confirmation signals to the arrival station remote control box.

[0016] Preferably, both the departure station remote control box and the arrival station remote control box are equipped with an emergency brake button. When the emergency brake button is pressed, the operation permissions of the departure station remote control box and the arrival station remote control box will be frozen and an alarm will be issued. At the same time, the motor direct control box will also stop its current operation.

[0017] Pressing the emergency brake button again will deactivate the emergency status of the departure station remote control box and the arrival station remote control box. The motor direct control box will then control the release hook to return to the blocking state via the electric push rod and the release hook connecting beam.

[0018] Preferably, the trolley includes a trolley side guard plate, pulleys, trolley mounting screws, and supporting steel pipes;

[0019] The pulleys are installed between the two outer pairs of pulley side guard plates, and the supporting steel pipes are installed between the two inner pulley side guard plates. The pulley axle of each pulley is tightly clamped by the pulley side guard plates on both sides to ensure that the pulleys do not wobble when the pulleys are running. The pulley mounting screws are installed on the outside of the outermost pulley side guard plate.

[0020] The inner diameter of the positioning steel pipe is slightly larger than that of the trolley mounting screw, and it is tightly clamped by the trolley side guard plates on both sides. This not only ensures that the distance between the pulleys on both sides is the same as the distance between the load-bearing cables, but also strengthens the overall structural strength of the trolley.

[0021] The present invention also provides a method for releasing a pulley with interlocking protection, which is applied to the above-mentioned pulley release device with interlocking protection, and specifically includes the following steps:

[0022] S1. Once the staff at the departure platform confirms that preparations are complete, they press the button on the departure station remote control box to send a command to the arrival platform, indicating that the departure platform is ready.

[0023] At the same time, the arrival station remote control box receives the instruction, the LED indicator light on the arrival station remote control box changes color, and the display module on the arrival station remote control box indicates the departure station status;

[0024] S2. After the staff at the arrival station completes the preparations, they press the button on the arrival station remote control box to send an instruction to the staff at the departure station, indicating that the arrival station is ready. At the same time, the departure station remote control box receives the instruction, the LED indicator on the departure station remote control box changes color, the display module on the departure station remote control box indicates the arrival station status, and the departure is unlocked.

[0025] S3. The staff at the departure platform press the button on the departure station remote control box to send a release command to the motor direct control box and send a command to the arrival station to indicate that the trolley has been released.

[0026] The motor control box receives the instruction and controls the electric push rod and the release hook connecting beam to raise the release hook, and the trolley begins to slide down by its own weight.

[0027] Upon receiving the instruction, the LED indicator on the arrival station remote control box changes color, and the display module on the arrival station remote control box indicates that the trolley has been released.

[0028] S4. The trolley enters the arrival platform. After the staff has completed the processing, they press the button on the arrival station remote control box to send a command to the departure platform, indicating that the trolley has arrived and the processing is complete.

[0029] Upon receiving the instruction, the LED indicator on the departure station remote control box changes color, and the display module on the departure station remote control box indicates that the trolley has entered the station.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] This interlocked pulley release device and method requires no modification to the existing pulley structure and can be adapted to various installation environments. The designed release hook, when lowered, prevents the pulley from leaving the station but does not hinder its entry. It can be used for both reciprocating and straight-line cableways. The entire device implements interlocking protection, meaning the departing station can only release the pulley upon receiving a confirmation signal from the arrival station. Furthermore, by manually adjusting the limiting components, accidental release of the release hook connecting beam due to touch switches can be prevented, ensuring the safety of the release hook connecting beam's release.

[0076] For specific usage instructions, please refer to [link / reference]. Figure 9-10 By fixing the wire rope metal structure 14 on the departure platform 13 and the departure platform, and then fixing the two ends of the carrying cable 1 to the wire rope metal structure 14, the pulley release device 11 with interlocking protection and the pulley 12 are installed on the carrying cable 1. At the same time, the pulley release device 11 with interlocking protection releases the pulley 12.

[0077] Implementation: 6:

[0078] Please see Figure 15-18 Based on the above embodiments, the trolley release device with interlocking protection further includes a manual adjustment and restriction assembly, which includes a spiral frame 18, a guide rod 19, a rotating shaft 20, an adjusting claw 21, a tension spring 22, a retaining ring 23, a restriction pin 24, a through groove 25, a stop bar 26, a vertical stop block 27, and a horizontal stop block 28.

[0079] The loop-shaped frame 18 is fixedly installed on one side of the motor mounting frame 7, and the two ends of the guide rod 19 are connected through the loop-shaped frame 18.

[0080] The adjusting jaw 21 is hinged to one end of the guide rod 19, and the adjusting jaw 21 can pull the guide rod 19 to move.

[0081] The limiting pin 24 is fixedly connected to the other end of the guide rod 19 and is located inside the spiral frame 18. A through slot 25 is opened inside the spiral frame 18, through which the limiting pin 24 can pass through the spiral frame 18.

[0082] The retaining ring 23 is fixedly sleeved on the outer wall of the inner part of the guide rod 19, and the tension spring 22 is sleeved on the outer wall of the inner part of the guide rod 19. One end of the tension spring 22 abuts against the retaining ring 23, and the other end abuts against the inner wall of the U-shaped frame 18.

[0083] Furthermore, in this embodiment, the rotating shaft 20 is disposed at the connection between one end of the guide rod 19 and the U-shaped frame 18, and the rotating shaft 20 is fixedly sleeved on the outer wall of the guide rod 19 and rotatably connected inside the U-shaped frame 18; one side of the rotating shaft 20 is fixedly connected to the adjusting claw 21.

[0084] The stop bar 26 is integrally connected to the outer wall of the rotating shaft 20, and the vertical stop block 27 and the horizontal stop block 28 are fixedly connected to the U-shaped frame 18; the vertical stop block 27 and the horizontal stop block 28 are configured to cooperate with the stop bar 26, so that the stop bar 26 is restricted to rotating at an angle of 90 degrees.

[0085] Specifically, in use, to prevent the release hook connecting beam 8 from being accidentally released due to the switch being touched, when the hook connecting beam 8 is not lowered, the adjusting jaw 21 is rotated 90 degrees counterclockwise, causing the guide rod 19 to rotate as well. This adjusts the limiting pin 24 to a state where it can pass through the through slot 25. Under the rebound force of the tension spring 22, the other end of the guide rod 19 is pushed into the motor mounting frame 7. At the same time, the other end of the guide rod 19 is located below the release hook connecting beam 8, which can block the release hook connecting beam 8 and prevent it from being lowered.

[0086] When the release hook connecting beam 8 needs to be released normally, the other end of the guide rod 19 can be retracted by pulling the adjusting jaw 21. Then, the adjusting jaw 21 and the guide rod 19 are rotated 90 degrees clockwise so that the limiting pin 24 remains perpendicular to the through groove 25 after passing through the through groove 25, thus limiting and fixing the other end of the guide rod 19. As a result, the guide rod 19 retracts, and the release hook connecting beam 8 is released normally, ensuring the safety of the release hook connecting beam 8.
