Content of the Utility Model

[0003] In order to solve the technical defects mentioned in the above background art, the purpose of the utility model is to provide an amusement tower crane.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] An amusement tower crane, which includes a base, a vertical support rotatably mounted horizontally on the base, a horizontal support horizontally installed at one end of the vertical support away from the base, a hanging basket device arranged at the distal end of the horizontal support, and a driving device for driving the horizontal support to rotate; the driving device includes a support, a mounting plate, a rotating motor, a contact member, an induction switch and a braking unit. The support is fixedly arranged at the upper end of the vertical support, and the rotating motor is fixedly arranged on the support; the output shaft of the rotating motor is fixedly connected to the mounting plate, and the horizontal support is fixedly mounted on the mounting plate. The rotating motor is used to drive the horizontal support to rotate horizontally; the contact member is arranged on one side of the mounting plate, the induction switch is arranged on the support, and the induction switch is arranged corresponding to the contact member for sensing whether the horizontal support rotates in place to decelerate the rotating motor; the braking unit is arranged on the side of the induction switch away from the contact member, and the braking unit is used to stop the horizontal support from rotating.

[0006] By adopting the above technical scheme, a contact member is arranged on the mounting plate to rotate together with the horizontal support, and an induction switch is fixedly arranged on the support. When the horizontal support is about to rotate to the set position, the induction switch senses the contact member to trigger the rotating motor to decelerate. When the horizontal support rotates to the set position, the braking unit forcibly stops the horizontal support from rotating, with double braking, improving the braking effect, so that the position of the hanging basket is parked more accurately and the entertainment performance is better.

[0007] Furthermore, the upper end of the contact piece is fixedly connected to the peripheral side of the mounting plate, the sensing switch protrudes from the support, and a groove is provided at the upper end of the sensing switch. When the lower end of the contact piece is located in the groove, the rotating motor slows down its rotation, making the sensing accuracy and efficiency higher and more accurate.

[0008] Furthermore, the braking unit includes a travel switch, a transmission rod, a brake block and a blocking member. The travel switch is arranged on the support and is located on the side of the induction switch away from the contact member. The transmission rod is arranged on the peripheral side of the mounting plate and is located on the side of the travel switch away from the induction switch, the brake block is arranged below the mounting plate, and the blocking member is arranged on the support. When the transmission rod contacts the travel switch, the rotating motor stops rotating, the brake block abuts against the blocking member, and the mounting plate and the horizontal bracket stop rotating, thereby improving the braking effect and accuracy.

[0009] Furthermore, the blocking member is configured as a bolt structure. A mounting hole is correspondingly provided at the upper end of the support, one end of the blocking member is threadedly connected to the mounting hole, and the other end of the blocking member protrudes from the upper surface of the support to be abutted against the lower end of the brake block, which has a simple structure, higher compatibility, and is also conducive to cost saving.

The annular plate at the upper end is provided with the mounting hole, and a connecting plate is provided below the annular plate at the upper end, and the travel switch is provided on the connecting plate, which has a compact structure and a more sensitive response.

[0011] Furthermore, the hanging basket device includes a lifting motor, a fixed seat, a winding drum, a hanging wire, an encoder and a hanging basket. The fixed seat is arranged at the far end of the horizontal bracket, and the lifting motor is fixed to one side of the fixed seat. The winding drum is rotatably arranged on the fixed seat, and the output shaft of the lifting motor is fixedly connected to one end of the winding drum to rotate the winding drum. One end of the hanging wire is wound on the winding drum, and the other end of the hanging wire is connected to the hanging basket. The encoder is fixedly connected to the other end of the winding drum, and is used to sense the up and down travel of the hanging wire to prevent the winding drum from being in a state of always paying out or taking up wire, thereby improving the accuracy of control.

[0012] In summary, the beneficial effects of the utility model are:

[0013] The mounting plate of the utility model is provided with a contact piece that rotates together with the horizontal bracket, and a sensing switch is fixedly provided on the support. When the horizontal bracket is about to rotate to the set position, the sensing switch senses the contact piece to trigger the rotating motor to slow down. When the horizontal bracket rotates to the set position, the braking unit forces the horizontal bracket to stop rotating, and the double braking improves the braking effect, so that the position of the hanging basket is more accurate and the entertainment performance is better.

[0023] The following will further elaborate on the embodiments of this utility model in conjunction with the attached Figures 1-4 drawings.

[0024] An amusement tower crane 1, as Figure 1 , Figure 2 , Figure 3 shown, includes a base 2, a vertical support 3 horizontally rotatable on the base 2, a horizontal support 4 horizontally installed at one end of the vertical support 3 away from the base 2, a hanging basket device 5 provided at the distal end of the horizontal support 4, and a driving device 6 for driving the horizontal support 4 to rotate. The driving device 6 includes a support 61, a mounting plate 62, a rotating motor 63, a contact member 64, an induction switch 65 and a braking unit. The support 61 is fixedly provided at the upper end of the vertical support 3, and the rotating motor 63 is fixedly provided on the support 61. The output shaft of the rotating motor 63 is fixedly connected to the mounting plate 62, and the horizontal support 4 is fixedly installed on the mounting plate 62. The rotating motor 63 is used to drive the horizontal support 4 to rotate horizontally. The contact member 64 is provided on one side of the mounting plate 62, the induction switch 65 is provided on the support 61, and the induction switch 65 is arranged corresponding to the contact member 64 for sensing whether the horizontal support 4 rotates in place to decelerate the rotating motor 63. The braking unit is provided on the side of the induction switch 65 away from the contact member 64, and the braking unit is used to stop the horizontal support 4 from rotating.

[0025] Among them, the contact member 64 is arranged on the mounting plate 62 and rotates together with the horizontal bracket 4, and the induction switch 65 is fixedly arranged on the support 61. When the horizontal bracket 4 is about to rotate to the set position, the induction switch 65 senses the contact member 64 to trigger the rotation motor 63 to decelerate. When the horizontal bracket 4 rotates to the set position, the braking unit forces the horizontal bracket 4 to stop rotating, and the double braking improves the braking effect, so that the position of the hanging basket is more accurate and the entertainment performance is better.

[0026] In this embodiment, please refer to Figure 2 The upper end of the contact piece 64 is fixedly connected to the peripheral side of the mounting plate 62, the sensing switch 65 is arranged on the protruding support 61, and a groove 651 is arranged on the upper end of the sensing switch 65. When the lower end of the contact piece 64 is located in the groove 651, the rotating motor 63 slows down the rotation, so that the sensing accuracy and the sensing efficiency are higher and more accurate.

[0027] The contact piece 64 is configured as a sheet structure, and the side surface of the contact piece 64 is consistent with the direction of its rotation, so that the induction switch 65 has more induction time to prevent the induction switch 65 from failing to sense the contact piece 64 due to excessive movement.

[0028] The brake unit includes a travel switch 661, a transmission rod 662, a brake block 663 and a blocking member. The travel switch 661 is arranged on the support 61 and is located on the side of the induction switch 65 away from the contact member 64. The transmission rod 662 is arranged on the peripheral side of the mounting plate 62 and is located on the side of the travel switch 661 away from the induction switch 65, the brake block 663 is arranged below the mounting plate 62, and the blocking member is arranged on the support 61. When the transmission rod 662 contacts the travel switch 661, the rotating motor 63 stops rotating, the brake block 663 abuts against the blocking member, and the mounting plate 62 and the horizontal bracket 4 stop rotating, thereby improving the braking effect and accuracy.

[0029] Specifically, the blocking member is configured as a bolt structure. Of course, it can also be configured as a protruding columnar or block structure. The upper end of the support 61 is correspondingly provided with a mounting hole 613, one end of the blocking member is threadedly connected to the mounting hole 613, and the other end of the blocking member protrudes from the upper surface of the support 61 to abut against the lower end of the brake block 663. The structure is simple, the compatibility is higher, and it is also conducive to cost saving.

[0030] Among them, the brake block 663 is set to a square structure, and the height of the blocking member can be adjusted by screwing in and out to match the corresponding brake block 663, which has higher compatibility and better practicality.

[0031] The support 61 is set as a cylindrical structure. Both ends of the support 61 are set as annular plates 61611, and multiple support columns 612 are arranged on the circumferential side of the support 61 to connect the annular plates 61611 at both ends. An installation hole 613 is arranged on the upper annular plate 61, and a connecting plate is arranged below the upper annular plate 61. The travel switch 661 is arranged on the connecting plate, with a compact structure and more sensitive response.

[0032] Specifically, in this embodiment, please refer to Figure 2 , Figure 3 , a set of contact member 64, brake block 663 and transmission rod 662 are provided. A set of travel switch 661, transmission rod 662, blocking member and induction switch 65 are arranged on both sides of the contact member 64. The contact member 64 and the transmission rod 662 are arranged on both sides of the mounting plate 62, enabling rapid braking whether the horizontal bracket 4 rotates forward or backward, suitable for various occasions and with stronger compatibility. In the figure, the blocking member is not drawn.

[0033] In this embodiment, please refer to Figure 1 , Figure 4 , the hanging basket 56 device 5 includes a lifting motor 51, a fixed seat 52, a wire winding disc 53, a suspension wire 54, an encoder 55 and a hanging basket 56. The fixed seat 52 is arranged at the distal end of the horizontal bracket 4, and the lifting motor 51 is fixed on one side of the fixed seat 52. The wire winding disc 53 is rotatably arranged on the fixed seat 52, and the output shaft of the lifting motor 51 is fixedly connected to one end of the wire winding disc 53 to make the wire winding disc 53 rotate. One end of the suspension wire 54 is wound around the wire winding disc 53, and the other end of the suspension wire 54 is connected to the hanging basket 56. The encoder 55 is fixedly connected to the other end of the wire winding disc 53, used to sense the up and down travel of the suspension wire 54, avoid the wire winding disc 53 being in a state of continuously paying out or taking in wire, and improve the control accuracy.

[0034] During use, left and right buttons 21 and up and down buttons 22 are arranged on the base 2. The user can operate the left and right buttons 21 and up and down buttons 22 to control the actions of the horizontal bracket 4 and the hanging basket 56 through the controller. When operating the left and right buttons 21, the rotation motor 63 is started and drives the mounting plate 62 and the horizontal bracket 4 thereon to rotate. When rotating to a certain angle, the contact member 64 passes through the groove 651, and the induction switch 65 transmits a signal to the controller, and the controller controls the rotation motor 63 to decelerate. After rotating a set angle, the transmission rod 662 contacts the travel switch 661 to cut off the power supply of the rotation motor 63, and the rotation motor 63 stops rotating. At the same time, the brake block 663 abuts against the blocking member, and a mechanical limit structure is adopted to forcibly stop the rotation of the horizontal bracket 4 to eliminate the small-angle rotation of the horizontal bracket 4 under the action of inertia, so that the hanging basket 56 is parked at the set position, improving the parking accuracy of the hanging basket 56.

[0035] When the user operates the up and down buttons 22, the lifting motor 51 starts, and the forward and reverse rotation of the winding disc 53 is controlled through the forward and reverse rotation of the lifting motor 51 to realize wire release or wire winding. Since the length of the suspension wire 54 is limited, the encoder 55 can be used to sense the length of the suspension wire 54 being lowered or wound to determine whether the hanging basket 56 reaches the set position, thereby controlling the lifting motor 51 to stop working.

[0036] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
