Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a steering device for facilitating the movement of crane tracks. Background Art

[0002] Cranes are large mechanical equipment used in outdoor environments such as ports. They are mainly used for loading and unloading of goods. During port operations, rail cranes are often needed to transfer containers in order to transport them to truck decks. Cranes have the characteristics of high site utilization, large operating range, and strong applicability. The steering gear is a guiding device used for the crane to walk or turn on the track, to ensure that the crane can move stably on the track and ensure the stability of the crane's steering.

[0003] The inventor found in his daily work that in the process of maintaining the crane steering gear, most of the existing crane steering gears on the market are large in size and heavy. When the staff disassemble and move them, they need to use tools such as carts to carry out the transportation operation. When using the cart for transportation, the steering gear must be lifted onto the cart. During the operation, improper operation may cause the steering gear to fall, posing a threat to the personal safety of the staff. When using the cart for transportation, the steering gear needs to be tied and fixed, and after moving to the designated area, the steering gear needs to be untied, resulting in a large number of operation steps and a long time consumption, which is inconvenient for the staff to move the steering gear. Utility Model Content

The magnetic force of the strong magnet is suitable for the working environment of the equipment, so that the C-shaped frame can be stably constrained on the equipment body, and the magnetic force of the strong magnet is set within the strength range that limits the C-shaped frame, thereby ensuring that the C-shaped frame is limited while the staff can easily unfold the auxiliary components.

[0006] Preferably, the first positioning block and the second positioning block are symmetrically arranged about the connecting plate, and a slot is provided on the side surface of the connecting plate. The rotating shaft passes through the surface of the connecting plate. By utilizing the cooperation between the first positioning block and the second positioning block, the rotation axis of the connecting plate can be limited and ensure that the connecting plate fits on the mounting frame.

[0007] Preferably, the limiting shaft passes through the side surface of the C-shaped frame, and the roller is located on the inner wall of the C-shaped frame. Through the cooperation between the limiting shaft and the C-shaped frame, the position of the roller can be supported to ensure that the rolling effect can be achieved after the roller is unfolded.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] In the utility model, by providing an auxiliary component and a restraining component, when the crane moves, the track wheel located on the track will cooperate with the track to guide the moving trajectory of the crane. At the same time, when the crane turns, the track wheel moves along the direction of the track, and under the guidance of the track, the crane is guided to turn. When the steering gear needs to be disassembled and repaired, the bolts fixing the steering gear are removed, and then the roller is turned, and the rolling force cooperates with the rotating shaft to pull the C-shaped frame, and the C-shaped frame pulls the strong magnet. The strong magnet is forced to break away from the installation frame and loses the constraint on the C-shaped frame. The C-shaped frame cooperates with the rotating shaft to pull the connecting plate while moving. The connecting plate rotates under the guidance of the first positioning shaft and the second positioning shaft, and gradually approaches the restraining pin. When the connecting plate contacts the restraining pin, the restraining pin is squeezed by the connecting plate and slides into the storage cavity. The restraining pin squeezes the limit spring while moving, and the limit spring is squeezed The restraining pin loses the restriction of the connecting plate and the pressure on the limit spring. The limit spring loses the pressure and rebounds, and pushes the restraining pin to reset and insert into the slot. After the restraining pin is inserted into the slot, it will limit the position of the connecting plate, and then the deployment operation of the auxiliary components will be completed. After the four sets of auxiliary components are deployed, the steering gear can be flattened to the side where the auxiliary components are installed, so that the steering gear is out of the track. After the steering gear is completely flattened, the auxiliary components will contact the ground, so that the staff can move the steering gear to the maintenance point. By setting the auxiliary components and the restraining components, it is convenient for the staff to disassemble and move the steering gear, thereby reducing the problem of long time spent by the staff when using a cart to move the steering gear, and further improving the work efficiency of the staff.

[0020] See also Figure 1-5 The utility model provides a technical solution: a steering device for facilitating the movement of a crane track, comprising a mounting frame 1, a cover plate 2 and an auxiliary component 5, the cover plate 2 being mounted on the upper surface of the mounting frame 1, a reinforcing column 3 being mounted on the inner wall of the mounting frame 1, a track wheel 4 being mounted on the inner wall of the mounting frame 1, the auxiliary component 5 being arranged on the side surface of the mounting frame 1, and a restraining component 6 being arranged on the side surface of the mounting frame 1.

[0021] The specific configuration and functions of the auxiliary component 5 and the restraining component 6 are described in detail below.

[0022] In this embodiment, the auxiliary component 5 includes a first positioning block 51, which is mounted on the side surface of the mounting frame 1, and a second positioning block 52 is mounted on the side surface of the mounting frame 1. The side surfaces of the first positioning block 51 and the second positioning block 52 are both provided with a rotation groove, and a connecting plate 53 is mounted on the inner wall of the first positioning block 51 and the second positioning block 52 located at the rotation groove, and a circular hole is opened on the surface of the connecting plate 53, and a rotating shaft 54 ​​is mounted on the inner wall of the circular hole of the connecting plate 53, and a C-shaped frame 55 is mounted on the side surface of the rotating shaft 54, and the C-shaped frame 55 is mounted on the side surface of the rotating shaft 54. A limiting shaft 56 is installed on the inner wall of the C-shaped frame 55, and a roller 57 is installed on the surface of the limiting shaft 56. A groove is opened on the side surface of the C-shaped frame 55, and a strong magnet 58 is installed on the inner wall of the C-shaped frame 55 located in the groove. The magnetic force of the strong magnet 58 is suitable for the working environment of the equipment, so that the C-shaped frame 55 can be stably constrained on the equipment body. By setting the magnetic force of the strong magnet 58 to be within the strength range of limiting the C-shaped frame 55, it is ensured that while limiting the C-shaped frame 55, it is convenient for the staff to unfold the auxiliary component 5.

[0023] Specifically, the first positioning block 51 and the second positioning block 52 are symmetrically arranged with respect to the connecting plate 53 . A slot is provided on a side surface of the connecting plate 53 , and the rotating shaft 54 ​​passes through the surface of the connecting plate 53 .

[0024] In this embodiment, the first positioning block 51 cooperates with the second positioning block 52 to limit the center of the rotation axis 54 of the connecting plate 53 and ensure that the connecting plate 53 fits on the installation frame 1.

[0025] Specifically, the limiting shaft 56 passes through the side surface of the C-shaped frame 55, and the roller 57 is located on the inner wall of the C-shaped frame 55. Through the cooperation of the limiting shaft 56 and the C-shaped frame 55, the position of the roller 57 can be supported to ensure that the roller 57 can achieve a rolling effect after being unfolded.

[0026] In this embodiment: the restraint assembly 6 includes a mounting block 61, which is mounted on the side surface of the mounting frame 1, a storage cavity is provided on the side surface of the mounting block 61, a connecting rod 62 is installed on the inner wall of the mounting block 61 located in the storage cavity, a limiting spring 63 is installed on the inner wall of the mounting block 61 located in the storage cavity, a restraining pin 64 is installed on the side surface of the connecting rod 62, the limiting spring 63 is fixedly connected to the side surface of the restraining pin 64, a side stopper 65 is installed on the side surface of the connecting rod 62, a guide groove 66 is provided on the side surface of the mounting block 61, and an extrusion block 67 is installed on the inner wall of the guide groove 66 of the mounting block 61.

[0027] In this embodiment: through the cooperation between the mounting block 61 and the connecting rod 62, the moving direction of the restraining pin 64 can be guided, reducing the probability of the restraining pin 64 being offset during the movement. At the same time, the cooperation between the limit spring 63 and the restraining pin 64 can stably be within the strength range of the limiting auxiliary component 5. When limiting the auxiliary component 5, the position of the auxiliary component 5 can be reliably constrained, and the smoothness of the limiting operation of the auxiliary component 5 can be ensured.

[0028] Specifically, there are two connecting rods 62, and the two connecting rods 62 are symmetrically arranged about the mounting block 61. The limit spring 63 is sleeved on the surface of the connecting rod 62, and the constraint pin 64 is located on the inner wall of the storage cavity. The constraint pin 64 is plugged into the inner wall of the slot. The limit spring 63 can be used to constrain the position of the constraint pin 64 to reduce the free movement of the constraint pin 64, thereby achieving the limiting effect of the constraint pin 64. At the same time, the connecting plate 53 moves under the guidance of the first positioning block 51 and the second positioning block 52. When the connecting plate 53 moves to the maximum angle and is at the same level as the constraint pin 64, the constraint pin 64 coincides with the slot and is accurately inserted into the slot under the push of the limit spring 63.

[0029] Specifically, the cross section of the side stopper 65 is chamfered, and a T-shaped protrusion is provided on the side of the extrusion block 67 close to the mounting block 61 . The protrusion is located on the inner wall of the guide groove 66 , and the extrusion block 67 contacts the surface of the side stopper 65 .

[0030] In this embodiment, through the cooperation between the protrusion on the extrusion block 67 and the guide groove 66, the position of the extrusion block 67 is constrained and the moving direction of the extrusion block 67 can be guided at the same time.

[0031] Working principle: when the steering gear needs to be disassembled and repaired, the bolts fixing the steering gear are removed, and then the roller 57 is turned, and the rolling force cooperates with the rotating shaft 54 ​​to pull the C-shaped frame 55, and the C-shaped frame 55 pulls the strong magnet 58. The strong magnet 58 is forced to separate from the installation frame 1 and loses the constraint on the C-shaped frame 55. While moving, the C-shaped frame 55 cooperates with the rotating shaft 54 ​​to pull the connecting plate 53. The connecting plate 53 rotates under the guidance of the first positioning axis and the second positioning axis, and gradually approaches the constraint pin 64. When the connecting plate 53 contacts the constraint pin 64, the constraint pin 64 is squeezed by the connecting plate 53 to slide into the storage cavity. The constraint pin 64 squeezes the limit spring 63 while moving, and the limit spring 63 is squeezed and deformed. When the connecting plate 53 is completely attached to the surface of the installation frame 1, the slot moves to the same horizontal plane as the constraint pin 64. At the same time, the restraining pin 64 loses the restriction of the connecting plate 53 and the pressure applied to the limit spring 63. The limit spring 63 loses the pressure and rebounds, and pushes the restraining pin 64 to reset and insert into the slot. After the restraining pin 64 is inserted into the slot, it will limit the position of the connecting plate 53, and then the deployment operation of the auxiliary component 5 will be completed. After the four groups of auxiliary components 5 are fully deployed, the steering gear can be flattened to the side where the auxiliary component 5 is installed, so that the steering gear is out of the track. After the steering gear is completely flattened, the auxiliary component 5 will contact the ground, so that the staff can move the steering gear to the maintenance point. By setting the auxiliary component 5 and the restraining component 6, it is convenient for the staff to disassemble and move the steering gear, thereby reducing the problem of a long time spent by the staff when using a cart to move the steering gear, and further improving the work efficiency of the staff.
