[0001] This application relates to the field of hoisting equipment technology, for example to a hoisting device for erecting a trestle bridge. Background Technology

[0002] A related technology (announcement number: CN216863455U) discloses a hoisting device for assembling a steel trestle bridge, including a base. A fixed rod is fixedly installed on the top of the base, and a cylinder is telescopically installed inside the fixed rod. An adjusting rod is connected to the moving end of the cylinder. A turntable is rotatably installed on the top of the adjusting rod and outside the fixed rod. A hoisting rod is fixedly installed on the top of the turntable. A transmission wheel is rotatably installed at the end of the hoisting rod, and a recovery wheel is rotatably installed on the top of the hoisting rod. A rope is wound around the outside of the transmission wheel on the outside of the recovery wheel. A fixed plate is fixedly connected to the bottom of the rope. A third motor is fixedly installed on one side of the fixed plate, and clamping plates are slidably installed on both sides of the bottom of the fixed plate. The device also includes a first motor, a second motor, and a third motor. The first motor drives the turntable to rotate, the second motor drives the recovery wheel to rotate, and the third motor drives the clamping plates on both sides to move in opposite directions.

[0003] In implementing the above embodiments, at least the following problems were found in the related technology:

[0004] The hoisting equipment used for assembling this steel trestle bridge uses a third motor to clamp or release materials via the side clamps. Controlling the second motor winds up the ropes, lifting the materials. Controlling the third motor rotates the hoisting boom, causing the materials to rotate as well. Controlling the cylinders allows for further adjustment of the material's height, facilitating operator use. However, the distance between the materials and the fixed boom cannot be adjusted, preventing the hoisting of materials at varying distances from the boom.

[0036] Combination Figures 1 to 4As shown, this embodiment of the present disclosure provides a hoisting device for erecting a trestle bridge, including a column 10, a support plate 20, a track 30, a trolley assembly 40, guide wheels 50, a winch 60, and a drive component 70. The column 10 is fixed to the ground or connected to other equipment, such as a trolley. The support plate 20 is rotatably mounted on the outer wall of the column 10, and the plane of the support plate 20 is perpendicular to the axis of the column 10. The support plate 20 can rotate relative to the column 10. The track 30 is installed on the top surface of the support plate 20 along the radial direction of the column 10, and is used to support the trolley assembly 40. The trolley assembly 40 is mounted on the track 30 and can travel along the track 30. The guide wheels 50 are mounted on the trolley assembly 40 along the height direction of the column 10, and are located below the track 30, used to change the direction of force. A winch 60 is mounted on the bottom surface of the support plate 20. The winch 60 includes a rope 61, which passes around a guide wheel 50 and is connected to a material gripping device or a material loading device. The material gripping device is used to grip materials, such as a robotic arm or a hook. The material loading device is used to load materials, such as a hopper. A drive unit 70 is mounted between the outer wall of the column 10 and the support plate 20 to provide driving force, driving the support plate 20 to rotate relative to the column 10.

[0037] This disclosure provides a hoisting device for erecting a trestle bridge. By controlling the winch 60, the rope 61 can be wound or released to lift or lower the material being grabbed or loaded. By controlling the drive unit 70, the support plate 20 can rotate relative to the column 10, ultimately causing the material grabbing or loading device to rotate around the column 10. By controlling the trolley to travel along the track 30, the distance between the guide wheel 50 and the column 10 can be changed, ultimately altering the distance between the material grabbing or loading device and the column 10. Therefore, the position of the material grabbing or loading device can be freely adjusted in a plane, enabling the lifting of materials at different locations.

[0038] Optionally, combined Figure 1 and Figure 4 As shown, the trolley assembly 40 includes an active part 41, a driven part 42, and a connecting plate 43. The active part 41 is mounted on the track 30 to provide power. The driven part 42 is mounted on the track 30 to maintain stability. Along the length of the track 30, the active part 41 and the driven part 42 are located on opposite sides of the track 30. The connecting plate 43 is installed between the active part 41 and the driven part 42 to determine their relative positions and to support the guide wheel 50. The guide wheel 50 is mounted on the bottom surface of the connecting plate 43.

[0039] In this embodiment, driven by the active part 41 and the driven part 42, the connecting plate 43 can move along the length direction of the track 30, thereby driving the guide wheel 50 to move along the length direction of the track 30, and ultimately changing the distance between the material gripping device or the material loading device and the column 10.

[0040] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, the winch 60 also includes a mounted bearing 62, a shaft 63, and a drum 64. The mounted bearing 62 is mounted on the bottom surface of the support plate 20 and supports the rotatable shaft 63. The shaft 63 is mounted on the mounted bearing 62 and supports the drum 64. The drum 64 is mounted on the shaft 63, and the rope 61 is wound around the drum 64. The shaft 63 can be rotated in a controlled manner to drive the drum 64 to rotate.

[0041] In this embodiment, the rotating shaft 63 can rotate under the drive of an external force. This, in turn, drives the drum 64 to rotate, ultimately winding up or releasing the rope 61, thereby changing the height of the material gripping device or the material loading device.

[0042] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, the winch 60 also includes a motor base 65 and a first motor 66. The motor base 65 is mounted on the bottom surface of the support plate 20 and is used to support and mount the first motor 66. The first motor 66 is mounted on the motor base 65, and the axis of the rotating end of the first motor 66 is parallel to the axis of the rotating shaft 63, which is used to provide driving force. The rotating shaft 63 rotates under the drive of the first motor 66.

[0043] In this embodiment, a first motor 66 is used as a power source to drive the rotating shaft 63 to rotate, thereby automatically changing the height of the material gripping device or the material loading device.

[0044] Optionally, combined Figure 1 , Figure 3 and Figure 4 As shown, the winch 60 also includes a first driving pulley, a first driven pulley, and a first belt 67. The first driving pulley is mounted on the rotating end of the first motor 66 and rotates under the drive of the first motor 66. The first driven pulley is mounted on the rotating shaft 63 and drives the rotating shaft 63 to rotate. The first belt 67 is fitted onto the first driving pulley and the first driven pulley and is used to transmit driving force. The diameter of the first driving pulley is smaller than the diameter of the first driven pulley.

[0045] In this embodiment, controlling the first motor 66 to operate drives the first driving pulley to rotate. The first belt 67 then drives the first driven pulley to rotate, which in turn drives the rotating shaft 63 to rotate, ultimately automatically changing the height of the material gripping or loading device. Furthermore, by using a design where the diameter of the first driving pulley is smaller than that of the first driven pulley, the rotational speed can be reduced, while the output torque can be increased.

[0046] Optionally, combined Figure 1 and Figure 4 As shown, the driving component 70 includes a support rod 71, a motor mounting plate 72, and a second motor 73. The support rod 71 is mounted on the top surface of the support plate 20 along the height direction of the column 10, supporting the motor mounting plate 72. The motor mounting plate 72 is mounted on the top of the support rod 71, supporting the second motor 73. The second motor 73 is mounted on the motor mounting plate 72 and provides driving force; the axis of the rotating end of the second motor 73 is parallel to the axis of the column 10. Driven by the second motor 73, the support plate 20 rotates relative to the column 10.

[0047] In this embodiment, a second motor 73 is used as a power source to drive the support plate 20 to rotate, ultimately causing the material gripping device or material loading device to automatically rotate around the column 10.

[0048] Optionally, combined Figure 1 and Figure 4 As shown, the drive unit 70 also includes a second driving pulley, a second driven pulley, and a second belt 74. The second driving pulley is mounted on the rotating end of the second motor 73 and supports the second belt 74. The second driven pulley is mounted on the outer wall of the column 10 and supports the second belt 74. The second belt 74 is fitted onto the second driving pulley and the second driven pulley to transmit driving force. The diameter of the second driving pulley is smaller than the diameter of the second driven pulley.

[0049] In this embodiment, controlling the second motor 73 to operate drives the second driving pulley to rotate. Torque is then transmitted to the second driven pulley via a belt. Since the column 10 is fixed to the ground or connected to other equipment, the support plate 20 rotates relative to the column 10 under the action of the reaction force, ultimately causing the material gripping device or material loading device to automatically rotate around the column 10.

[0050] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a bearing housing 80, a deep groove ball bearing 90, and an angular contact ball bearing 100. The bearing housing 80 is mounted on the support plate 20 and sleeved on the column 10. The deep groove ball bearing 90 is mounted between the bearing housing 80 and the column 10. The angular contact ball bearing 100 is mounted opposite to the bearing housing 80 and the column 10.

[0051] In this embodiment, the bearing housing 80 supports and mounts the deep groove ball bearing 90 and the angular contact ball bearing 100, and limits their movement. The deep groove ball bearing 90 bears radial force, while the oppositely mounted angular contact ball bearing 100 bears both axial and radial forces. The deep groove ball bearing 90 and the oppositely mounted angular contact ball bearing 100 together reduce the friction between the support plate 20 and the column 10, and improve the rotational accuracy of the support plate 20 relative to the column 10.

[0052] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a sealing cover 110. The sealing covers 110 are respectively installed at both ends of the bearing housing 80, and the sealing covers 110 at both ends abut against the deep groove ball bearing 90 and the angular contact ball bearing 100 respectively.

[0053] In this embodiment, both end caps 110 serve as sealing and protection, and respectively limit the axial movement of the deep groove ball bearing 90 and the angular contact ball bearing 100.

Other embodiments may include structural and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary. Parts and features of some embodiments may be included or substituted for parts and features of other embodiments.
