Description

Technical Field

[0001] This utility model belongs to the field of hoisting technology, and specifically relates to a synchronous belt hoist for suspended conveyor lines. Background Technology

[0002] A hoist is a core mechanical device for vertical (or near-vertical) conveying of materials or personnel. With its efficient and stable lifting capabilities, it plays a crucial role in industries such as manufacturing, construction, and mining. Hoists for overhead conveyor lines are vertical transport equipment specifically designed for overhead conveyor systems. They are primarily used to connect overhead conveyor lines at different heights, enabling the vertical lifting and docking of materials (such as workpieces, pallets, and finished products) with the conveyor lines.

[0003] When a suspended conveyor hoist is in operation, its movable track needs to be aligned with the conveyor track. However, due to installation structure or load limitations, existing hoists are prone to deviation during lifting, resulting in a significant misalignment between the movable track and the conveyor track, thus hindering the successful completion of the task. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a synchronous belt hoist for suspended conveyor lines, aiming to solve the above technical problems.

[0005] Technical solution: In order to achieve the above objectives, this utility model provides a synchronous belt hoist for a suspended conveyor line, including: a frame, a cantilever mechanism and a counterweight assembly, wherein the top of the frame is provided with a drive assembly for driving the cantilever mechanism, and the cantilever assembly and the counterweight assembly are slidably disposed on both sides of the frame.

[0006] The cantilever mechanism includes a movable frame, on which multiple sets of limiting guide wheel sets are provided. The limiting guide wheel sets include horizontal limiting guide wheel sets located on both sides of the movable frame and front and rear limiting guide wheel sets located in the middle of the movable frame. Each set of horizontal limiting guide wheel sets and front and rear limiting guide wheel sets includes a set of guide wheels arranged opposite to each other.

[0007] The frame includes a set of vertically arranged columns and a T-shaped guide rail between two columns. The columns are made of H-beams, and the T-shaped guide rail has a T-shaped cross-section. The horizontal limiting guide wheel assembly and the front and rear limiting guide wheel assembly cooperate with the T-shaped guide rail and the columns, respectively. The horizontal limiting guide wheel assembly cooperates with the T-shaped guide rail to guide the moving frame and restrict its movement in the horizontal direction, while the front and rear limiting guide wheel assembly cooperates with the columns to guide the moving frame and restrict its movement in the depth direction.

[0008] The drive assembly includes a set of annular synchronous belts, and both the cantilever mechanism and the counterweight assembly are connected to the annular synchronous belts.

[0009] Furthermore, the drive assembly also includes a drive motor located at the top of the frame, a transmission shaft connected to the output end of the drive motor via a coupling, a set of synchronous pulleys on the transmission shaft, and an annular synchronous belt wound around the synchronous pulleys.

[0010] Furthermore, the counterweight assembly includes a counterweight mounting frame. At each of the four corners of the mounting frame are guide wheels with the same structure as the guide wheel sets, which cooperate with the columns to achieve front-to-back positioning. At the top of the mounting frame is a set of lateral guide wheels that cooperate with the columns to achieve horizontal positioning. When the counterweight mounting frame moves, the guide wheels and the lateral guide wheels achieve horizontal positioning and vertical guidance.

[0011] Furthermore, the limiting guide wheel assembly also includes a guide wheel base and a spacing adjustment block. The guide wheel base has a set of oblong holes, through which bolts pass to connect it to the movable frame. The guide wheels are mounted on the guide wheel base, and the spacing adjustment block is mounted on the movable frame. The spacing adjustment block is connected to the side of the guide wheel base by bolts. The gap between the two guide wheels can be changed by the installation position of the guide wheel base.

[0012] Furthermore, a set of proximity switches and a set of limit switches are provided at the upper and lower parts of the column. The limit switches can stop the cantilever mechanism after it reaches its designated position, and prevent it from overtraveling.

[0013] Furthermore, it also includes a lifting assembly, which comprises a movable track and a fixed track;

[0014] The cantilever mechanism also includes a set of cantilever arms mounted on a movable frame. Each cantilever arm has a movable track, and the fixed track is installed on one side of the object being transported. The cantilever assembly can move up and down along the movable track, allowing the movable track and the fixed track to engage or disengage.

[0015] Furthermore, both the cantilever mechanism and the counterweight assembly are connected to an annular synchronous belt via synchronous belt clamps. The cantilever mechanism and counterweight assembly are raised or lowered by a set of synchronous belts, ensuring that the rising or falling rates at both ends are consistent. This prevents the moving track from tilting after reaching the docking position, which could lead to difficulties in docking or even prevent docking from being completed.

[0016] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0017] 1) This utility model provides a synchronous belt hoist for suspended conveyor lines. A set of annular synchronous belts is driven by synchronous pulleys on the drive shaft, ensuring that the moving frame and counterweight mounting frame rise and fall at the same speed on both sides without deviation, thus ensuring the subsequent docking accuracy of the moving track. 2) Both the moving frame and the counterweight mounting frame are equipped with guide wheels with guiding and limiting functions, providing good guidance and limiting movement in the longitudinal and horizontal directions, further improving the docking accuracy of the moving track. 3) The proximity switch and limit switch form a double-safety mechanism. After the cantilever assembly moves into position, the proximity switch detects and controls the drive motor to stop, while the limit switch detects its travel distance to prevent it from exceeding the docking position, further improving the docking accuracy between the moving track and the fixed track.

[0030] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0031] like Figure 1-7 As shown: A synchronous belt hoist for a suspended conveyor line includes: a frame 1, a cantilever mechanism 2 and a counterweight assembly 3. The top of the frame 1 is provided with a drive assembly 4 for driving the cantilever mechanism 2. The cantilever assembly 2 and the counterweight assembly 3 are slidably disposed on both sides of the frame 1.

[0032] The cantilever mechanism 2 includes a movable frame 21, on which multiple sets of limiting guide wheel sets are provided. The limiting guide wheel sets include horizontal limiting guide wheel sets 23 on both sides of the movable frame 21 and front and rear limiting guide wheel sets 24 in the middle of the movable frame 21. Each set of horizontal limiting guide wheel sets 23 and front and rear limiting guide wheel sets 24 includes a set of guide wheels 22 arranged opposite to each other.

[0033] The frame 1 includes a set of vertically arranged columns 11 and a T-shaped guide rail 12 between two columns 11. The columns 11 are H-shaped steel, and the cross section of the T-shaped guide rail 12 is T-shaped. The horizontal limiting guide wheel set 23 and the front and rear limiting guide wheel set 24 respectively cooperate with the T-shaped guide rail 12 and the columns 11.

[0034] like Figure 3 As shown, in this embodiment, two sets of horizontal limiting guide wheel sets 23 are provided in the middle of the moving frame 21. The gap between the two guide wheels 22 in the horizontal limiting guide wheel set 23 is engaged with the vertically arranged protrusion on the T-shaped guide rail 12. When the moving frame 21 rises or falls, the horizontal limiting guide wheel set 23 rolls on the T-shaped guide rail 12 to achieve guidance. At the same time, the gap between its guide wheels restricts the horizontal tilting of the moving frame 21 when it moves. The column 11 is an H-shaped steel, which provides a matching installation position for the front and rear limiting guide wheel sets 24. Similarly, the front and rear limiting guide wheel sets 24 can guide the moving frame 21 and limit it in the depth direction.

[0035] The drive assembly 4 includes a set of annular synchronous belts 41, and the cantilever mechanism 2 and the counterweight assembly 3 are both connected to the annular synchronous belts 41.

[0036] like Figure 2As shown, the drive assembly 4 also includes a drive motor 42 located at the top of the frame 1, and a transmission shaft 43 connected to the output end of the drive motor 42 via a coupling. A set of synchronous pulleys 44 are provided on the transmission shaft 43, and an annular synchronous belt 41 is wound around the synchronous pulleys 44. The drive motor 42 drives the transmission shaft 43 to rotate, and the rotation speed of the synchronous pulleys 44 on the transmission shaft 43 is consistent with the rotation speed of the annular synchronous belt 41 wound around the synchronous pulleys 44. This ensures that the movement speed of the cantilever mechanism 2 and the counterweight assembly 3 connected to the annular synchronous belt 41 is consistent on both sides, guaranteeing their stable vertical upward and downward movement.

[0037] Specifically, the counterweight assembly 3 includes a counterweight mounting frame 31. The four corners of the counterweight mounting frame 31 are provided with guide wheel sets 32 that cooperate with the column 11 to achieve front and rear limit and have the same structure as the limit guide wheel set. The top of the counterweight mounting frame 31 is provided with a set of transverse limit guide wheel sets 33 that cooperate with the column 11 to achieve horizontal limit.

[0038] In a preferred embodiment, the limiting guide wheel assembly further includes a guide wheel base 25 and a spacing adjustment block 26. The guide wheel base 25 has a set of oblong holes, through which bolts pass to connect it to the movable frame 21. The guide wheels 22 are mounted on the guide wheel base 25, and the spacing adjustment block 26 is mounted on the movable frame 21. The spacing adjustment block 26 is connected to the side of the guide wheel base 25 by bolts. The spacing between the guide wheels 22 in the same group can be adjusted by the installation position of the guide wheel base 25, and its adjustment range is the length of the oblong holes. The bolts on the spacing adjustment block 26 are connected to the side of the guide wheel base 25. Rotating the bolts can adjust the spacing between the two to match the guide wheel gap adjustment. At the same time, the spacing adjustment block 26 provides a reverse force to the guide wheel base 25 through the bolts, preventing the guide wheel base 25 from moving due to the long-term action of the guide wheels 22, which would cause the guide wheel gap to increase and lose its guiding and limiting functions.

[0039] Specifically, a set of proximity switches 5 and a set of limit switches 6 are provided at the upper and lower parts of the column 11. After the cantilever mechanism 2 rises or falls to its designated position, the proximity switch 5 detects this and issues a command to stop the drive motor 42. The limit switch 6 detects the travel distance to prevent overtravel and improves docking accuracy.

[0040] Specifically, it also includes a lifting assembly, which includes a movable rail 28 and a fixed rail 29;

[0041] The cantilever mechanism 2 also includes a set of cantilever 27s mounted on the movable frame 21. The cantilever 27s are provided with movable rails 28, and the fixed rails 29 are installed on one side of the transport target object.

[0042] Furthermore, in this embodiment, the docking of the movable track 28 and the fixed track 29 is achieved with a high-precision docking using a docking locking mechanism. The movable track 28, the fixed track 29, and the docking locking mechanism in this patent are identical in structure and principle to those described in Chinese Patent Publication No. CN115009790B, entitled "A Light-Load Suspended Conveying Lift Track Docking Locking Mechanism, System, and Method," and detailed information can be found in that patent.

[0043] Preferably, both the cantilever mechanism 2 and the counterweight assembly 3 are connected to the annular synchronous belt 41 via synchronous belt clamps.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
