Description

Technical Field

[0001] This utility model relates to the field of trolley stopping technology, specifically a trolley stopping device for port machinery maintenance. Background Technology

[0002] Windproof equipment for large vehicles is necessary during their operation, such as rail clamps and anchors. These devices greatly enhance the vehicle's wind resistance. However, in strong winds, rail clamps and anchors cannot fully guarantee the safety of the large vehicle. To prevent the vehicle from moving due to strong winds, these devices are used.

[0003] A search revealed Chinese patent application number 202220829705.4, which discloses a trolley stopping device for port machinery maintenance. This patent includes a support assembly and a clamping assembly. The support assembly consists of two unit support bodies rotatably connected by connectors. Pins are provided on both sides of each unit support body for insertion into anchoring holes on the dock. A rubber pad is provided on the lower surface of each unit support body. The pins and rubber pads work together to fix the support assembly to the ground. A clamping assembly is slidably mounted on the support assembly. The clamping assembly includes two clamping units symmetrically connected by a lead screw. Rotating the lead screw adjusts the distance between the two clamping units to clamp the wheel. This patent features a novel structure, simple operation, convenient transfer, and good stopping effect. The adjustable clamping of the clamping assembly effectively prevents the wheel from rotating and causing the trolley to move, greatly improving the safety of the device.

[0004] Although the aforementioned patent is simple to operate, easy to transfer, and has a good stopping effect, and the adjustable clamping component can effectively prevent the wheel from rotating and causing the trolley to move, it has revealed obvious defects in actual use. First, the support component of this patent requires the trolley wheel to be precisely pressed onto the unit support, making it difficult for operators to predict the wheel's position during operation, which significantly increases the installation difficulty and affects work efficiency. Second, the semi-circular clamping plate of this patent has a closed structure design, which is difficult to adapt to baffles, pipelines, and other components that may be above the trolley wheel, and is prone to incomplete clamping, resulting in a significant reduction in windproof and stopping performance, and failing to meet the stopping requirements of trolleys in complex working environments. Third, since the size of the semi-circular clamping plate of this patent is fixed, if its size does not match the wheel, it can easily cause local overpressure, damaging the anti-slip texture on the wheel surface, thereby affecting the stopping effect of the trolley.

[0005] Therefore, it is necessary to study a trolley stop device for port machinery maintenance. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a trolley stop device for port machinery maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a trolley stop device for port machinery maintenance, comprising a support bar, a movable groove on the inner side of the support bar, a movable column rotatably connected inside the movable groove, one end of the movable column extending to the outer side of the support bar and fixedly connected to a crank handle, a movable block threadedly connected to the surface of the movable column, and the movable block slidably connected to the movable groove, a semi-circular block symmetrically fixedly connected to the inner side of the support bar and the surface of the movable block, a reinforcing groove on the outer side of the semi-circular block, a hollow plate rotatably connected to the top of the inner groove of the reinforcing groove, a reinforcing plate slidably connected to the bottom of the hollow plate, four symmetrical fixing grooves on the surface of the reinforcing plate, and fixing bolts symmetrically threadedly connected to the surface of the hollow plate, and the fixing bolts engaging with the fixing grooves.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4As shown, this utility model provides a trolley stop device for port machinery maintenance, including a support bar 1. A movable groove 2 is formed on the inner side of the support bar 1. A movable column 3 is rotatably connected to the inside of the movable groove 2 via a bearing. One end of the movable column 3 extends to the outer side of the support bar 1 and is fixedly connected to a crank handle 4. A movable block 5 is threadedly connected to the surface of the movable column 3, and the movable block 5 is slidably connected to the movable groove 2. A semi-circular block 6 is symmetrically fixedly connected to the inner side of the support bar 1 and the surface of the movable block 5. A groove is formed on the outer side of the semi-circular block 6. The reinforcement groove 7 has a hollow plate 8 rotatably connected to its inner top via a damping shaft. The bottom of the hollow plate 8 is slidably connected to a reinforcement plate 9. The surface of the reinforcement plate 9 has four symmetrical fixing grooves 10. When the reinforcement plate 9 is retracted, the two lower symmetrical fixing grooves 10 are aligned with the fixing bolts 11. When the reinforcement plate 9 is fully extended, the two upper symmetrical fixing grooves 10 are aligned with the fixing bolts 11. The surface of the hollow plate 8 is symmetrically threaded with fixing bolts 11, and the fixing bolts 11 are engaged with the fixing grooves 10.

[0023] refer to Figure 3 and Figure 4 The surface of the support bar 1 has several positioning grooves 12 evenly arranged in a ring around the movable column 3. The outer side of the crank handle 4 has a sliding opening 13. The inside of the sliding opening 13 is slidably connected to a positioning bolt 14, and the positioning bolt 14 is used in conjunction with the positioning groove 12.

[0024] As a technical optimization of this utility model, the positioning groove 12 opened on the surface of the support bar 1 about the moving column 3, and the positioning bolt 14 in the outer sliding opening 13 of the crank handle 4, can be used together to position the rotation position of the crank handle 4, thereby accurately controlling the position of the semi-arc block 6 and improving the accuracy and stability of clamping.

[0025] refer to Figure 4 The surface of the sliding port 13 is symmetrically fixedly connected to the limiting block 15, and the surface of the positioning bolt 14 is symmetrically provided with the limiting groove 16, and the limiting groove 16 is slidably connected to the limiting block 15.

[0026] As a technical optimization of this utility model, the setting of the limiting block 15 and the limiting groove 16 can limit the sliding of the positioning bolt 14, prevent the positioning bolt 14 from disengaging from the sliding port 13, ensure the reliability of the positioning function, and at the same time, enable the positioning bolt 14 to be used as the handle of the crank 4.

[0027] refer to Figure 3 An auxiliary groove 17 is provided on the inner side of the support bar 1, and an auxiliary block 18 is slidably connected to the inner side of the auxiliary groove 17. The auxiliary block 18 is fixedly connected to the semi-arc block 6.

[0028] As a technical optimization of this utility model, the auxiliary groove 17 and the auxiliary block 18 further clarify their auxiliary support and guiding role for the semi-arc block 6, making the semi-arc block 6 more stable during movement and improving the overall stability and reliability of the device.

[0029] refer to Figure 2 A limiting frame 19 is fitted on the surface of the hollow plate 8, and a limiting ring 20 is fixedly connected to the surface of the fixing bolt 11, and the limiting ring 20 is slidably connected to the limiting frame 19.

[0030] As a technical optimization of this utility model, the limiting frame 19 on the surface of the hollow plate 8 and the limiting ring 20 on the surface of the fixing bolt 11 are slidably connected, which can limit the rotation and movement of the fixing bolt 11, ensure the snap-fit ​​effect between the fixing bolt 11 and the fixing groove 10, and enhance the stability of the fixing of the reinforcing plate 9.

[0031] refer to Figure 1 and Figure 2 The surface of the semi-circular block 6 is provided with several evenly arranged anti-slip ridges 21, and a rubber block is fixedly connected to the bottom of the semi-circular block 6.

[0032] As a technical optimization of this utility model, the anti-slip protrusions 21 provided on the surface of the semi-circular block 6 can increase the friction with the wheel and prevent the wheel from slipping; the rubber block at the bottom of the semi-circular block 6 can increase the contact friction with the ground and at the same time play a buffering role, further improving the stopping effect and the stability of the device.

[0033] The working principle and usage process of this utility model are as follows: When using this trolley stopping device to stop the trolley, the operator first moves the support bar 1 to the side of the trolley wheel, so that the semi-circular block 6 on the inner side of the support bar 1 initially abuts against the side of the wheel. At this time, the rubber block at the bottom of the semi-circular block 6 contacts the ground, providing initial stable support through friction. The anti-slip convex strips 21 on the surface increase the contact friction with the wheel, preventing the device from shifting. Subsequently, the operator holds the crank handle 4 and rotates it, driving the moving column 3 to rotate within the moving groove 2 through the bearing. When the crank handle 4 is rotated, the surface of the movable column 3 is threadedly connected to the movable block 5. During rotation, the movable block 5 slides along the movable groove 2, thereby pushing the semi-circular block 6 towards the wheel. At this time, the auxiliary block 18 in the auxiliary groove 17 slides synchronously with the semi-circular block 6. Through the guiding effect of the auxiliary groove 17, the movement trajectory of the semi-circular block 6 is ensured to be stable, avoiding deviation. When the two semi-circular blocks 6 are in contact with the wheel surface, the crank handle 4 is stopped from rotating. At this time, the positioning bolt 14 in the sliding opening 13 on the outside of the crank handle 4 can be inserted into the positioning groove 12 on the surface of the support bar 1. The sliding engagement between the limiting block 15 and the limiting groove 16 locks the position of the crank handle 4, preventing the moving column 3 from rotating in the opposite direction and ensuring stable clamping force. To enhance the stopping effect, the hollow plate 8 inside the reinforcing groove 7 on the outside of the semi-circular block 6 can be rotated out through the damping shaft, and the reinforcing plate 9 can be pulled down to slide out from the bottom of the hollow plate 8. When the reinforcing plate 9 is fully pulled out, the two upper fixing grooves 10 are aligned with the fixing bolts 11 on the surface of the hollow plate 8. Tighten the fixing bolts 11 to make them lock into the fixing grooves 10. At this time, the reinforcing plate 9 is supported on the ground, along with the rubber block. Together, they form a multi-point support structure. Conversely, when storing, the reinforcing plate 9 is pushed into the hollow plate 8, and the lower fixing groove 10 is engaged with the fixing bolt 11, which facilitates the transfer of the device. The limiting ring 20 on the surface of the fixing bolt 11 is slidably connected to the limiting frame 19 outside the hollow plate 8, which can prevent the fixing bolt 11 from being over-screwed or loosened. The sliding fit between the reinforcing plate 9 and the hollow plate 8 and the multi-level fixing groove 10 design can adapt to different wheel diameters. By adjusting the extension length of the reinforcing plate 9, it is ensured that the reinforcing structure is in close contact with the ground, further enhancing the wind resistance.
