Description

Technical Field

[0001] The invention relates to the technical field of cableway transportation equipment, and in particular to a tensioning hydraulic device for a sealed load-bearing rope of a reciprocating passenger cableway. Background Art

[0002] In cableway transportation equipment, the load-bearing rope is a key component for carrying passengers and transporting objects. Its stability and tension are crucial to the safe operation of the cableway. Existing cableway load-bearing rope tensioning devices mostly use mechanical or manual adjustment methods, which have problems such as low adjustment accuracy, complex operation, and high maintenance costs. In addition, with the continuous development of cableway transportation technology, the requirements for the tension and adjustment accuracy of the load-bearing rope are becoming higher and higher.

[0003] For example, a cableway load-bearing rope tensioning device described in patent number CN201210012345.6 realizes the tensioning adjustment of the load-bearing rope by hydraulic means, but the structure is complex and the installation and maintenance are inconvenient. The device adopts hydraulic means for tensioning adjustment, involving multiple hydraulic components such as hydraulic cylinders, hydraulic pumps, and hydraulic valves, making the overall structure relatively complex. The complex structure not only increases the difficulty of installation, but also increases the maintenance cost, because the repair and replacement of hydraulic components usually require professional knowledge and skills. The leakage problem in the hydraulic system is also a common maintenance difficulty. Once leaked, it not only affects the tensioning effect, but also may cause pollution to the surrounding environment. In terms of uneven tensioning force, when the hydraulic system performs the tensioning operation, due to the low compressibility of the liquid, once improperly controlled, it may cause uneven force on the load-bearing rope, thereby affecting the stability and safety of the cableway. The nonlinear characteristics of the hydraulic system may also cause fluctuations in tensioning force, making it difficult to achieve precise tensioning control. Especially when the cableway system needs to run for a long time, the device is prone to failure, affecting the safety and stability of the cableway. In terms of proneness to failure, after long-term operation, the components in the hydraulic system (such as seals, pumps, valves, etc.) are prone to wear and aging, resulting in an increase in the failure rate. Failures in the hydraulic system are often difficult to locate and resolve quickly, which may affect the normal operation of the ropeway and the safety of passengers.

[0004] In addition, the cableway load-bearing rope tensioning device disclosed in patent number CN201520023456.7, although relatively simple in structure, is not flexible enough in clamping and releasing operations during the tensioning process. The device may not be able to achieve fast and accurate adjustment when clamping and releasing the load-bearing rope due to the limitation of the mechanical structure. The design of the clamping mechanism may not be reasonable enough, resulting in excessive pressure or friction on the load-bearing rope during the clamping process, affecting its service life and safety. It is impossible to achieve remote control and automatic adjustment. The device lacks the functions of remote control and automatic adjustment, so the operator needs to manually adjust the tension, which is not only inefficient, but also may cause safety accidents due to human error. In modern cableway transportation equipment, intelligence and automation have become a development trend, and the device cannot meet this demand. The operation efficiency is low. Due to the inability to achieve fast and accurate adjustment and remote control, the operator needs to spend more time and energy to monitor and adjust the tension of the load-bearing rope. This not only reduces the operating efficiency of the cableway, but also may affect the comfort and satisfaction of passengers. Summary of the invention

[0005] In view of the problems and shortcomings existing in the prior art, the present invention proposes a tensioning hydraulic device for a sealed bearing rope of a reciprocating passenger ropeway, aiming to solve the problems of low adjustment accuracy, complex operation, high maintenance cost and uneven tensioning force of the existing ropeway bearing rope tensioning device.

[0006] Specifically, the technical solution provided by the present invention is: a tensioning hydraulic device for a sealed load-bearing rope of a reciprocating passenger ropeway, comprising:

[0007] The rope clamping mechanism is composed of a wedge block 1, a wedge block 2, a pulley, a support frame, and a connecting rod 2. The wedge block 1 and the wedge block 2 are respectively clamped and assembled on the upper and lower ends of the wire rope. The top of the wedge block 1 and the bottom of the wedge block 2 are equipped with a support frame. The top support frame of the wedge block 1 is connected to the longitudinally arranged connecting rod 2 by screws. A rotatable pulley is assembled at the end of the connecting rod 2. The pulley is rollingly assembled on the wire rope to drive the rope clamping mechanism as a whole to move on the rope body.

[0008] The hydraulic mechanism is composed of a rope-clamping hydraulic cylinder and a connecting rod. The rope-clamping hydraulic cylinder is arranged on a support frame at the top of the wedge-shaped block. The end of the rope-clamping hydraulic cylinder is connected to the connecting rod through a bearing. Both ends of the connecting rod are equipped with bearings. One end of the connecting rod is transmission-connected to the rope-clamping hydraulic cylinder, and the other end is connected to the support frame at the bottom of the wedge-shaped block.

[0009] Furthermore, the support frame is provided with a plurality of holes for assembling transmission bearings or fastening bolts.

[0010] Furthermore, the tensioning hydraulic device adopts a method of using two sets of devices in conjunction when in use. The support frame of the first set of tensioning hydraulic device is connected to a matching tensioning hydraulic cylinder through a connecting piece. The other end of the tensioning hydraulic cylinder is connected to the support frame of the second set of tensioning hydraulic device through a transmission accessory. The linkage coordination of the two sets of tensioning hydraulic devices is achieved through the tensioning hydraulic cylinder.

[0011] Furthermore, the support frame of the second set of tensioning hydraulic device is connected with an anchoring wire rope.

[0012] Furthermore, the steel wire rope is wound around a matching rope reel.

[0013] Further, the rope winding wheel is arranged at the base.

[0014] Furthermore, in the rope clamping mechanism, the wedge block 1 and the wedge block 2 are wedge-shaped and are used to clamp and assemble at the upper and lower ends of the steel wire rope, and by cooperating to clamp the steel wire rope, ensure that the rope clamping mechanism can be firmly fixed on the steel wire rope;

[0015] The pulley is a rotatable wheel body, which is assembled at the end of the second connecting rod. The pulley is rollingly assembled on the wire rope to drive the rope clamping mechanism to move on the rope body as a whole, providing smooth movement performance;

[0016] The support frame is a structure assembled with the top and bottom of wedge block one and wedge block two. The support frame is used to connect wedge block one and wedge block two and support connecting rod one and connecting rod two to improve the overall structural stability. The support frame is provided with multiple holes for assembling transmission bearings or fastening bolts; connecting rod two is a longitudinally arranged rod body, one end of which is connected to the support frame and the other end is equipped with a pulley. Connecting rod two transmits the rolling motion of the pulley, so that the rope clamping mechanism can move along the wire rope.

[0017] Furthermore, in the hydraulic mechanism, the rope clamping hydraulic cylinder is arranged on the support frame and connected to the connecting rod 1 through the bearing. The rope clamping hydraulic cylinder provides hydraulic power to drive the wedge block 2 to move through the connecting rod 1, thereby clamping or releasing the wire rope;

[0018] Both ends of the connecting rod 1 are equipped with bearing parts, one end is connected to the rope clamping hydraulic cylinder for transmission, and the other end is connected to the support frame at the bottom of the wedge block 2. The connecting rod 1 transmits the power of the rope clamping hydraulic cylinder to realize the movement of the wedge block 2.

[0019] Compared with the prior art, the advantages of the present invention are: 1) improving the adjustment accuracy: the tension adjustment of the load-bearing rope is achieved through the hydraulic mechanism, which has the characteristics of high adjustment accuracy and fast response speed, and can meet the requirements of modern cableway transportation equipment for tensioning accuracy; 2) simplifying operation and maintenance: the rope clamping mechanism and the hydraulic mechanism are reasonably designed, compact in structure, easy to install and maintain, and reduce the complexity of operation and maintenance cost; 3) enhancing stability and safety: the coordinated clamping mode of wedge block 1 and wedge block 2 ensures that the rope clamping mechanism can be firmly fixed on the wire rope, thereby improving the stability and safety of the cableway system; 4) realizing remote control and automatic adjustment: through the setting of the hydraulic mechanism, remote control and automatic adjustment can be easily realized, thereby improving the operating efficiency and the intelligence level of the cableway system; 5) optimizing the smooth movement performance: the pulley is rollingly assembled on the wire rope, and through the transmission of the connecting rod 2, the rope clamping mechanism can move smoothly along the wire rope, thereby reducing friction and resistance and improving the operation efficiency of the cableway system.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] like Figure 1 and Figure 2 As shown, the device includes a rope clamping mechanism and a hydraulic mechanism. The specific structural features, connection methods and functions of the components are as follows:

[0026] 1. Rope clamping mechanism

[0027] Wedge block 1 4 and wedge block 2 5: As the main modules for clamping the steel wire rope 3, both have a wedge-shaped structure and can be assembled at the upper and lower ends of the steel wire rope 3 to ensure that the rope clamping mechanism is firmly fixed on the steel wire rope 3 through cooperative clamping.

[0028] Support frame 7: It is assembled with the top and bottom of wedge block 1 4 and wedge block 2 5, and is used to connect wedge block 1 4 and wedge block 2 5 and support connecting rod 1 2 and connecting rod 2 8 to improve the overall structural stability. Support frame 7 is provided with a plurality of holes for assembling transmission bearings or fastening bolts.

[0029] Pulley 6: It is a rotatable wheel body, which is assembled on the end of the connecting rod 2 8 and is rollingly assembled on the wire rope 3 to drive the rope clamping mechanism as a whole to move on the rope body and provide smooth movement performance.

[0030] The second connecting rod 8 is a rod body arranged longitudinally, one end of which is connected to the support frame 7 and the other end is equipped with a pulley 6, which transmits the rolling motion of the pulley 6 so that the rope clamping mechanism can move along the wire rope 3.

[0031] 2. Hydraulic mechanism

[0032] Rope clamping hydraulic cylinder 1: It is arranged on the support frame 7, connected with the connecting rod 2 through the bearing, and provides hydraulic power.

[0033] Connecting rod 1 2: Both ends are equipped with bearings, one end is connected to the rope clamping hydraulic cylinder 1 through bearing transmission, and the other end is connected to the support frame 7 at the bottom of the wedge block 2 5. Connecting rod 1 2 transmits the power of the rope clamping hydraulic cylinder 1. When the hydraulic cylinder pushes, connecting rod 1 2 drives wedge block 1 4 and wedge block 2 5 to open the jaws; when the rope clamping hydraulic cylinder 1 is tightened, connecting rod 1 2 drives wedge block 1 4 and wedge block 2 5 to tighten the wire rope 3.

[0034] Embodiment 2

[0035] Based on the first embodiment, Figure 1 and Figure 2 As shown, the usage of this device is:

[0036] 1. Installation and connection

[0037] The device is installed on the steel wire rope 3 and connected to the supporting hydraulic station. The end is anchored on the base 11 to ensure the stability and safety of the device.

[0038] 2. Tensioning operation

[0039] In the initial state, the first set of tensioning hydraulic device is tightened, the rope clamping hydraulic cylinder 1 is pressurized and clamps the wire rope 3 through the wedge block 1 4 and the wedge block 2 5. The second set of tensioning hydraulic device is in the open state, and the wire rope 3 passes through the second set of tensioning hydraulic device and enters the matching wire rope anchor cylinder. After the rope clamping hydraulic cylinder 1 of the first set of tensioning hydraulic device has completed its stroke, the second set of tensioning hydraulic device clamps the wire rope 3. Open the first set of tensioning hydraulic device, and the rope clamping hydraulic cylinder 1 pushes the first set of tensioning hydraulic device forward to the maximum stroke. Use the first set of tensioning hydraulic device to tighten the wire rope 3 again, and repeat the operation in sequence until the required tension is reached.

[0040] Embodiment 3

[0041] On the basis of the first and second embodiments, Figure 1 and Figure 2 As shown, the specific implementation of the device:

[0042] 1. Installation preparation: First, determine the number and location of the required tensioning hydraulic devices according to the specific layout and length of the cableway system. Then, reserve installation holes on the base 11 so that the ends of the devices can be anchored on the base.

[0043] 2. Device installation: Install the tensioning hydraulic devices one by one on the wire rope 3 to ensure that the rope clamping mechanism can correctly clamp the wire rope 3. At the same time, connect the hydraulic station and pipeline to ensure that the hydraulic mechanism can work normally.

[0044] 3. Tensioning operation: Perform tensioning operation step by step according to the above working mode and working principle. During the operation, the parameters and quantity of the tensioning hydraulic device can be adjusted according to the actual situation and needs of the cableway system to achieve the best tensioning effect.

[0045] 4 Monitoring and maintenance: During use, the tensioning hydraulic device should be monitored and maintained regularly to ensure that it is in good working condition. At the same time, worn parts and hydraulic oil should be replaced in time to ensure the long-term use of the device.

[0046] Embodiment 4

[0047] On the basis of the first and second embodiments, Figure 1 and Figure 2 As shown, after the device is installed, the rope clamping hydraulic cylinder 1 of the first set of tensioning hydraulic device is in a pressurized state, and the wedge block 1 4 and the wedge block 2 5 are driven by the connecting rod 1 2 to clamp the wire rope 3. At this time, the second set of tensioning hydraulic device is in a standby state, its rope clamping hydraulic cylinder 1 is not pressurized, and the wedge block 1 4 and the wedge block 2 5 are in an open state, allowing the wire rope 3 to pass freely.

[0048] When the wire rope 3 needs to be tensioned, the hydraulic station first provides pressure to the rope clamping hydraulic cylinder 1 of the first tensioning hydraulic device to make it reach the maximum stroke, at which time the wire rope 3 is tightly clamped. Subsequently, the second tensioning hydraulic device is started, and its rope clamping hydraulic cylinder 1 begins to increase pressure, pushing the wedge block 1 4 and the wedge block 2 5 through the connecting rod 1 2 to gradually clamp the wire rope 3. At the same time, the rope clamping hydraulic cylinder 1 of the first tensioning hydraulic device begins to release pressure, and the connecting rod 1 2 drives the wedge block 1 4 and the wedge block 2 5 to loosen, so that the wire rope 3 can continue to move forward under the action of the second tensioning hydraulic device.

[0049] When the rope clamping hydraulic cylinder 1 of the second tensioning hydraulic device reaches the maximum stroke, the steel wire rope 3 has been further tensioned. At this time, the first tensioning hydraulic device is pressurized again to prepare for the next round of tensioning operation. By alternately using the first and second tensioning hydraulic devices, the steel wire rope 3 can be gradually tensioned to the desired degree.

[0050] During the entire tensioning process, the pulley 6 rolls on the steel wire rope 3 and transmits motion through the connecting rod 8, so that the rope clamping mechanism can move smoothly along the steel wire rope 3, reducing friction and resistance and improving the operating efficiency of the cableway system.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
