Description

Technical Field

[0001] This utility model relates to the field of aerial ropeway technology, and in particular to a structure for easy replacement of pressure sheaves on aerial ropeways. Background Technology

[0002] After prolonged use, the rubber pads of the support sheaves of the aerial cableway passenger device will wear out, and the sheaves may also be damaged. Therefore, the sheaves need to be replaced. In order to facilitate the replacement, a structure that facilitates the replacement of the support sheaves is needed.

[0003] In most existing sheave structures, hooks or similar structures are used to secure the sheave rope during use. However, the sheave rope can become taut due to its own weight and the weight of objects on it, causing it to detach from the sheave. This not only poses a danger, but the taut rope is also difficult to adjust, hindering sheave replacement and making it inconvenient to put it back on the sheave. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a structure for convenient replacement of pressure sheaves on aerial cableways.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A structure for easy replacement of sheaves on aerial cableways includes:

[0007] A fixed outer shell is provided, with an installation plate fixedly mounted on the inner wall of the fixed outer shell. An installation shaft is rotatably mounted on the side wall of the installation plate. A fixed cable pulley is fixedly mounted on the installation shaft by fixing screws. A drive device is fixedly mounted on the installation plate.

[0008] The support structure includes a fixed ring rotatably sleeved on a mounting shaft, an adjusting plate fixedly mounted on the side wall of the fixed ring, a movable plate slidably connected to the side wall of the adjusting plate, a support plate fixedly connected to the movable plate via a mounting rod, a sliding block fixedly connected to the side wall of the movable plate, a sliding groove corresponding to the sliding block on the adjusting plate, and a transmission structure installed inside the fixed housing.

[0009] Preferably, the transmission structure includes a fixed gear ring, which is fixedly connected to the inner wall of the fixed housing via a support rod. A reciprocating screw is rotatably connected to the inner wall of the sliding groove. The reciprocating screw passes through the inner wall of the sliding groove and extends to the outside of the adjusting plate. The reciprocating screw is mechanically engaged with the sliding block. A fixed gear is fixedly installed on the reciprocating screw, and the fixed gear meshes with the fixed gear ring. An adjusting structure is installed on the mounting shaft.

[0010] Preferably, the adjustment structure includes a fixing groove on the side wall of the fixing ring, a fixing block is slidably sleeved on the mounting shaft, and the fixing block matches the fixing groove. A fixing spring is fixedly connected to the side wall of the fixing groove. The fixing spring is rotatably connected to the mounting plate. Metal iron is embedded inside the fixing block, and an electromagnet is embedded inside the mounting plate.

[0011] Preferably, a fixed cover plate is rotatably mounted on the side wall of the fixed housing via a rotating shaft, and a control button corresponding to the electromagnet is fixedly mounted on the fixed cover plate.

[0012] Preferably, the support plate, the movable plate, and the adjusting plate are all made of synthetic plastic.

[0013] Preferably, the support plate is arc-shaped, and the shape of the support plate matches that of the fixed cable pulley.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the cable pulley is lifted by the arc-shaped support plate, and after being lifted, the cable pulley is located outside the fixed cable pulley, and its shape corresponds to the fixed cable pulley.

[0019] Reference Figures 1-3 A structure for convenient replacement of sheaves on aerial cableways, comprising:

[0020] A fixed outer shell 1 is fixedly installed on the inner wall of the fixed outer shell 1. A mounting plate 3 is fixedly installed on the side wall of the mounting plate 3. A mounting shaft 4 is rotatably installed on the side wall of the mounting plate 3. A fixed cable wheel 2 is fixedly installed on the mounting shaft 4 by fixing screws. A drive device is fixedly installed on the mounting plate 3.

[0021] The support structure 6 includes a fixed ring 7 rotatably sleeved on the mounting shaft 4. An adjusting plate 63 is fixedly installed on the side wall of the fixed ring 7. A movable plate 62 is slidably connected to the side wall of the adjusting plate 63. A support plate 61 is fixedly connected to the movable plate 62 via a mounting rod. A sliding block 64 is fixedly connected to the side wall of the movable plate 62. A sliding groove 65 corresponding to the sliding block 64 is opened on the adjusting plate 63. A transmission structure is installed inside the fixed housing 1.

[0022] Under the action of the transmission structure, the support plate 61 rotates. At the same time, during the rotation of the support plate 61, the sliding block 64 moves outward, driving the moving plate 62 to move together, so that the support plate 61 also moves outward, lifting the cable sheave.

[0023] The transmission structure includes a fixed gear ring 5, which is fixedly connected to the inner wall of the fixed housing 1 via a support rod. A reciprocating screw 66 is rotatably connected to the inner wall of the sliding groove 65. The reciprocating screw 66 passes through the inner wall of the sliding groove 65 and extends to the outer side of the adjusting plate 63. The reciprocating screw 66 is mechanically engaged with the sliding block 64. A fixed gear 67 is fixedly installed on the reciprocating screw 66. The fixed gear 67 meshes with the fixed gear ring 5. When the fixed gear 67 rotates one revolution along the fixed gear ring 5, the sliding block 64 can move back and forth once. An adjusting structure is installed on the mounting shaft 4.

[0024] Under the action of the adjustment structure, the fixed ring 7 rotates with the rotation of the mounting shaft 4, causing the fixed gear 67 to rotate. Under the action of the fixed gear ring 5, the fixed gear 67 will rotate on its own during the rotation, thereby driving the reciprocating screw 66 to rotate on its own, causing the sliding block 64, which is mechanically engaged with the reciprocating screw 66, to move.

[0025] The adjustment structure includes a fixing groove 8 on the side wall of the fixing ring 7, a fixing block 9 slidably sleeved on the mounting shaft 4, and the fixing block 9 matches the fixing groove 8. A fixing spring 10 is fixedly connected to the side wall of the fixing groove 8. The fixing spring 10 is rotatably connected to the mounting plate 3. Metal iron is embedded inside the fixing block 9, and an electromagnet is embedded inside the mounting plate 3.

[0026] When the mounting shaft 4 rotates, it will drive the fixed block 9, which is slidably sleeved on its outer side, to rotate together. After the electromagnet is disconnected, the elastic force of the fixed spring 10 pushes the fixed block 9 to move towards the fixed slot 8, so that the fixed block 9 is inserted into the fixed slot 8, fixing the fixed ring 7 and the mounting shaft 4 together. At this time, the rotation of the mounting shaft 4 can drive the fixed ring 7 to rotate.

[0027] A fixed cover plate is rotatably mounted on the side wall of the fixed housing 1 via a rotating shaft. The fixed housing 1 has an opening corresponding to the cable pulley rope. A control button corresponding to the electromagnet is fixedly mounted on the fixed cover plate. The fixed cover plate closes the fixed housing 1 to protect the equipment inside. The control button is used to control the conduction and disconnection of the electromagnet.

[0028] The support plate 61, the movable plate 62 and the adjusting plate 63 are all made of synthetic plastic. Synthetic plastic has high strength and low weight, which is beneficial to the adjustment of the device. At the same time, when the support plate 61 does not need to be adjusted, the fixed gear 67 and the fixed gear ring 5 can be locked, so that the support plate 61 does not rotate under the action of gravity.

[0029] The support plate 61 is arc-shaped, and its shape matches that of the fixed sheave 2. Therefore, after the support plate 61 lifts the sheave rope, the shape of the lifted rope is consistent with that of the fixed sheave 2, which makes it easy to replace the fixed sheave 2.

[0030] In this invention, when using the device, first open the fixed cover and press the control button. After the control button is pressed, the electromagnet will be disconnected for a period of time. After the electromagnet is disconnected, the elastic force of the fixed spring 10 pushes the fixed block 9 to move towards the fixed slot 8, so that the fixed block 9 is engaged in the fixed slot 8, fixing the fixed ring 7 and the mounting shaft 4 together. At this time, the rotation of the mounting shaft 4 can drive the fixed ring 7 to rotate. Start the drive device to make the mounting shaft 4 rotate, which drives the fixed ring 7 to rotate together. When the fixed ring 7 rotates, the adjusting plate 63 rotates accordingly, driving the moving plate 62 to rotate together, so that the support plate 61 also rotates. At the same time, the rotation of the adjusting plate 63... The movement causes the fixed gear 67 to rotate. Under the action of the fixed gear ring 5, the fixed gear 67 will rotate on its own axis during the rotation, thereby driving the reciprocating screw 66 to rotate as well. This causes the sliding block 64, which is mechanically engaged with the reciprocating screw 66, to move. The sliding block 64 will move outward, driving the moving plate 62 to move as well, causing the support plate 61 to also move outward, lifting the cable sheave. After the support plate 61 rotates to the side wall of the fixed cable sheave 2, the electromagnet is turned on, and the support plate 61 stops rotating. Then, the fixed cable sheave 2 is disassembled and replaced. After the replacement is completed, the drive device is started and the control button is pressed to return the support plate 61 to its original position.
