Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting equipment technology, and in particular to a dual-power-source driven trolley. Background Technology

[0002] As the primary form of subway transportation, the efficiency, technical sophistication, and safety of underground tunnel construction are of paramount importance. Currently, underground tunnel construction generally employs large-scale tunnel boring machines for excavation, combined with precast concrete segment support. This method is fast, efficient, highly mechanized, has minimal environmental impact, and ensures high-quality tunnel construction.

[0003] As a crucial precast component in subway tunnel engineering, the reliability and efficiency of segment transportation directly impact the safety and progress of tunnel construction. Current technologies typically employ segment cranes for lifting segments, which generally include a traveling mechanism serving as the power source and lifting equipment for hoisting the segments.

[0004] Normally, segment hoists move on straight tracks. However, with advancements in tunnel boring machine (TBM) technology, some segment hoists need to traverse both level and sloping sections of track. Currently, segment hoists generally operate stably on level tracks. However, when traversing sloping tracks, only the traveling mechanism provides power during the climb. In practice, this results in poor climbing ability and slow climbing speed, leading to excessive load on the motor and, in severe cases, even slippage, failing to meet the requirements for horizontal segment hoisting. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the driving force of the traveling mechanism of the segment crane is insufficient when it encounters a track with a certain slope, resulting in excessive load on the equipment.

[0010] In one embodiment of the present invention, a connecting shaft is provided on the rear side of the frame along the driving direction of the trolley, and a connecting lock assembly is provided on the connecting shaft for connecting the driven component.

[0011] In one embodiment of the present invention, the connecting latch assembly includes a first hinge joint, a first pin, a connecting rod, a second pin, and a second hinge joint. The first hinge joint is connected to the connecting shaft, and the first hinge joint is hinged to one end of the connecting rod via the first pin. The second hinge joint is hinged to the other end of the connecting rod via the second pin, and the second hinge joint is connected to the driven component.

[0013] In one embodiment of this utility model, two buffers are provided on the front side of the frame along the direction of travel of the driving trolley, and the buffers are respectively located on both sides of the center of the track beam.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example

[0026] Reference Figure 1-3As shown, the dual-power-source driven trolley of this utility model includes several parts: a frame 1, a power assembly 2, a gear assembly 3, and a track beam 4; the frame 1 is provided with a traveling wheel 11; the power assembly 2 consists of two symmetrically arranged components, and the power assembly 2 is mounted on the frame 1; the gear assembly 3 is disposed on the frame 1, and the gear assembly 3 is connected to the power assembly 2; the track beam 4 is provided with a rack 5, the traveling wheel 11 is disposed in the groove of the track beam 4, and the traveling wheel 11 can roll along the track beam 4; the gear assembly 3 meshes with the rack 5, and the two power assemblies 2 drive the gear assembly 3 to move along the rack 5. The track beam 4 is an "I" beam. Preferably, there are four traveling wheels 11, which are located at the four corners of the rectangle. The traveling wheels 11 are placed in pairs in the grooves on both sides of the "I" beam. When the power assembly 2 drives the frame 1 to move along the track beam 4 as a power source, the traveling wheels 11 roll in the grooves on both sides of the "I" beam as traveling components.

[0027] In the above structure, the power assembly 2 includes a running motor 21, a reducer 22, and a drive wheel 23. Both the running motor 21 and the reducer 22 are mounted on the frame 1 and are connected. The output end of the reducer 22 is connected to the drive wheel 23, which meshes with the gear assembly 3. The output end of the running motor 21 is connected to the input end of the reducer 22, thus the power source formed by the running motor 21 and the reducer 22 drives the drive wheel 23 to rotate.

[0028] In the above structure, the gear assembly 3 includes a rotating shaft 31, a first drive gear 32, and two second drive gears 33. Both ends of the rotating shaft 31 are mounted on the frame 1. The first drive gear 32 and the two second drive gears 33 are all sleeved on the rotating shaft 31, with the first drive gear 32 positioned between the two second drive gears 33. The drive wheel 23 meshes with the second drive gear 33, and the first drive gear 32 meshes with the rack 5. Two power components 2 are symmetrically arranged on both sides of the frame 1, and the two second drive gears 33 are also symmetrically arranged, with each second drive gear 33 corresponding to one of the two power components 2. Thus, each second drive gear 33 meshes with its corresponding drive wheel 23. To ensure stability, the rotating shaft 31, the first drive gear 32, and the two second drive gears 33 are coaxially arranged.

[0029] This utility model's dual-power-source driven trolley is based on a gear and rack transmission system driven by two motors 21, achieving stable operation through the meshing of gears and racks. To ensure good meshing of gears and racks, the distance between them can be adjusted by adjusting the wheel set.

[0030] Since the running motors 21 are all facing the same direction, a counterweight needs to be installed at the other end of the frame 1 to maintain balance. Therefore, a counterweight 6 is provided on the frame 1, which is used to balance the weight of the running motors 21.

[0031] To mitigate the impact of collisions caused by malfunctions or operational errors, two buffers 12 are provided on the front side of the frame 1 along the direction of travel of the trolley, with the buffers 12 located on both sides of the center of the track beam 4. The frame 1 is equipped with guide wheels 13, which contact the side wall of the track beam 4 and are capable of rolling along the track beam 4. Example

[0032] Based on the structure of Embodiment 1, and referring to Figure 4 , 5 As shown, a connecting shaft 7 is provided on the rear side of the frame 1 along the direction of travel of the driving trolley. A connecting locking assembly 8 is provided on the connecting shaft 7, and the connecting locking assembly 8 is used to connect the driven component. The connecting shaft 7 is used to install the connecting locking assembly 8 to connect the driving trolley and the driven trolley.

[0033] In the above structure, the connecting locking assembly 8 includes a first hinge joint 81, a first pin 82, a connecting rod 83, a second pin 84, and a second hinge joint 85. The first hinge joint 81 is connected to the connecting shaft 7, and the first hinge joint 81 is hinged to one end of the connecting rod 83 via the first pin 82. The second hinge joint 85 is hinged to the other end of the connecting rod 83 via the second pin 84, and the second hinge joint 85 is connected to the driven component. The first hinge joint 81 has a first connecting hole 811, and the second hinge joint 85 has a second connecting hole 851. The connecting shaft 7 passes through the first connecting hole 811.

[0034] In the above structure, the connecting rod 83 has a structure with low ends and a convex middle, and the convex bend in the middle of the connecting rod 83 faces one side of the track beam 4. The first pin 82 and the second pin 84 are respectively connected to the low ends of the connecting rod 83.

[0035] The connecting locking assembly 8 consists of a first hinge joint 81, a first pin 82, a connecting rod 83, a second pin 84, and a second hinge joint 85. The first hinge joint 81 and the second hinge joint 85 are respectively connected to the connecting shaft 7 on the driving trolley and the driven trolley. This connecting locking assembly 8 enables relative rotation between the driving trolley and the driven trolley in the horizontal and vertical directions, allowing the segment crane to better turn horizontally and move up and down slopes.

[0036] The connecting rod 83 has a bent structure with low ends and a convex middle, which can effectively avoid collisions between the segments and the connecting locking assembly 8 during operation, and is also more conducive to going uphill and downhill. The connecting rod 83 has an opening in the middle position, which can prevent collisions with the straight rack 5 at the bottom of the track beam 4 and the highest point of the segment end when it is at its highest position.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
