Description

Technical Field

[0001] This utility model relates to the field of large vehicle anchoring technology, specifically to a large vehicle anchoring device that can operate on one side and is anti-jamming. Background Technology

[0002] As an essential safety device for dock cranes, the trolley anchoring device is widely used in various loading and unloading machinery such as gantry cranes, quay cranes, and quay cranes. The trolley anchoring device is usually located in the middle of the end beam or lower crossbeam and mainly consists of a base, anchoring frame, rotating shaft, rotating handle, anchoring plate, and fixing pin.

[0003] As attached Figure 6 and attached Figure 7 As shown, the anchoring frame typically consists of an anchoring plate, a rotating handle, and a fixing pin on each of its left and right sides, connected by a pivot. In the working state (not anchoring), simply pressing down on one side to rotate the handle simultaneously lifts both anchoring plates, which are then secured with the fixing pins. In the non-working state (when anchoring is required), pressing down on the handle removes the fixing pins on both sides. Under gravity, the anchoring plate smoothly inserts into the anchoring pit, preventing the crane from sliding along the track.

[0004] However, as attached Figure 8 As shown, this conventional anchoring device has the following problems during use: When the wheels deviate to one side of the track due to unevenness of the track or wheel movement, the insert plate on one side may not be able to be properly placed into the anchoring pit. Since the two anchor plates are connected by the same shaft, neither insert plate can be placed into the anchoring pit. Consequently, this safety device fails, and in severe windy weather, it cannot effectively prevent the crane from slipping, posing a significant safety hazard.

[0005] Therefore, there is an urgent need for a trolley anchoring device that can operate on one side and prevent jamming, in order to solve the problem that conventional anchoring devices are at risk of failure when the wheels deviate to one side of the track. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing a unilaterally operable and jam-proof large vehicle anchoring device, thereby solving the problem that conventional anchoring devices are at risk of failure when the wheels deviate to one side of the track.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A unilaterally operable and anti-jamming large vehicle anchoring device includes two sets of anchoring components. The two sets of anchoring components are respectively installed on the left and right sides of the anchoring frame. The anchoring components include a rotating handle, a mounting base, a connecting rod, and an anchoring plate. The mounting base is disposed on the side of the anchoring frame. The middle section of the rotating handle is rotatably mounted on the mounting base. One end of the rotating handle is hinged to a connecting rod, and the anchoring plate is hinged to the connecting rod. The mounting base includes a seat sleeve, a rotating shaft, a bearing, and a bushing. The seat sleeve is installed on the side wall of the anchor frame. The rotating shaft is located inside the seat sleeve. The rotating shaft and the seat sleeve are rotatably connected by the bearing. One end of the rotating shaft extends away from the anchor frame and is connected to a rotating handle. A bushing is fitted on the rotating shaft between the seat sleeve and the rotating handle. An oil passage connecting to the bearing is opened through the side wall of the bushing.

[0008] To optimize the above technical solution, the specific measures also include: Furthermore, the oil passage is located at the opening on the side wall of the bushing and is connected to an oil nozzle.

[0009] Furthermore, the rotating shaft and the bearing are connected by a spacer.

[0010] Furthermore, the bearing is a rolling bearing.

[0011] Furthermore, it also includes a first limit switch and a second limit switch. The oil passage of the bearing is connected to the lubrication pump. The first limit switch and the second limit switch are both installed on the side of the anchoring frame and are electrically connected to the lubrication pump respectively. The first limit switch is triggered by rotating the handle when the anchoring plate is inserted into the anchoring pit. The second limit switch is triggered by rotating the handle when the anchoring plate is removed from the anchoring pit.

[0012] Furthermore, the end of the rotating shaft is perpendicularly connected to a rotating handle via bolts that are in the same direction as the shaft axis.

[0013] Furthermore, the end of the rotating shaft is provided with two threaded holes along the axial direction, and the rotating handle is provided with a mounting groove. A baffle is provided in the mounting groove, and two mounting holes are provided on the baffle corresponding to the threaded holes. Two bolts pass through the corresponding mounting holes and are threaded into the threaded holes of the rotating shaft.

[0014] Furthermore, the bushing includes a lubrication bushing and a rotating handle bushing. The oil passage is provided on the lubrication bushing. The rotating handle bushing is T-shaped and is slidably sleeved on the rotating shaft. The wide end of the T-shaped rotating handle bushing is located on the side away from the anchor frame. The lubrication bushing is slidably sleeved on the outer side of the narrow end of the T-shaped rotating handle bushing. A spring is connected between the side of the lubrication bushing near the wide end of the T-shaped rotating handle bushing and the wide end of the T-shaped rotating handle bushing. The spring is used to provide a force that moves the lubrication bushing and the rotating handle bushing away from each other.

[0015] Furthermore, a counterweight is provided at the end of the rotating handle away from the anchor plate.

[0016] The beneficial effects of this utility model are: This invention installs two sets of anchoring components on the left and right sides of the anchoring frame, forming two independent anchoring devices. When the wheel deviates to one side of the track, the two independent anchoring devices have separate adjustment space, ensuring that at least one anchoring plate is positioned in the pit. This prevents the entire anchoring device from malfunctioning due to one anchoring plate not being able to be lowered. It greatly ensures equipment safety during emergency anchoring in non-working conditions. This solves the problem of conventional crane trolley anchoring devices where both anchoring plates cannot be properly inserted into the anchoring pit when the trolley wheels deviate to one side, thus rendering the entire anchoring device ineffective. Simultaneously, an oil passage is opened on the bushing to facilitate lubrication of the bearing, greatly reducing friction and preventing the problem of impaired movement due to hinge point jamming.

[0017] This invention features a simple and practical structure. By using two separate anchoring devices, it increases the adjustment space and can accommodate situations where the wheels are biased to one side of the track, preventing the simultaneous deployment of anchoring plates. At least one anchoring device is guaranteed to function, greatly ensuring crane safety. The bearings and other components used are standard products, facilitating adjustment and ensuring stable stress distribution. The remaining parts are simple to manufacture and widely applicable. Furthermore, the addition of a lubrication pump allows for automatic lubrication based on the limit position, reducing the workload of manual lubrication. This invention has wide applicability, can be standardized, and is suitable for all cranes with counterweight-type trolley anchoring devices. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] As attached Figure 1 and attached Figure 2 As shown, a unilaterally operable and anti-jamming large vehicle anchoring device according to an embodiment of the present invention includes two sets of anchoring components. The two sets of anchoring components are respectively installed on the left and right sides of the anchoring frame. The anchoring component includes a rotating handle, a mounting base, a connecting rod, and an anchoring plate. The mounting base is disposed on the side of the anchoring frame. The middle section of the rotating handle is rotatably disposed on the mounting base. One end of the rotating handle is hinged to a connecting rod, and the anchoring plate is hinged to the connecting rod. The mounting base includes a seat sleeve 3, a rotating shaft 1, a bearing 4, and a bushing. The seat sleeve 3 is installed on the side wall of the anchor frame. The rotating shaft 1 is located inside the seat sleeve 3. The rotating shaft 1 and the seat sleeve 3 are rotatably connected by the bearing 4. One end of the rotating shaft 1 extends away from the anchor frame and is connected to a rotating handle. A bushing is fitted on the rotating shaft 1 between the seat sleeve 3 and the rotating handle. An oil passage connecting to the bearing 4 is opened through the side wall of the bushing.

[0022] This invention installs two sets of anchoring components on the left and right sides of the anchoring frame, forming two independent anchoring devices. When the wheel deviates to one side of the track, the two independent anchoring devices have separate adjustment space, ensuring that at least one anchoring plate is positioned in the pit. This prevents the entire anchoring device from malfunctioning due to one anchoring plate not being able to be lowered. It greatly ensures equipment safety during emergency anchoring in non-working conditions. This solves the problem of conventional crane trolley anchoring devices where both anchoring plates cannot be properly inserted into the anchoring pit when the trolley wheels deviate to one side, thus rendering the entire anchoring device ineffective. Simultaneously, an oil passage is opened on the bushing to facilitate lubrication of the bearing 4, greatly reducing friction and preventing the problem of malfunction due to hinge point jamming.

[0023] In another specific embodiment based on the above, the oil passage is located at the opening on the side wall of the bushing and is connected to an oil nozzle 5. In this solution, the oil nozzle 5 is used to connect to the lubrication pump. The standard design of the oil nozzle 5 and the oil passage allows for direct addition of lubricating oil, ensuring that the hinge point will not experience jamming.

[0024] In another specific embodiment based on the above, the rotating shaft 1 and the bearing 4 are connected by a spacer 2.

[0025] In another specific embodiment based on the above, bearing 4 is a rolling bearing. Rolling bearings greatly reduce friction and prevent hinge point jamming.

[0026] As attached Figure 5 As shown, in another specific embodiment based on the above, a first limit switch 9 and a second limit switch 10 are also included. The oil passage of the bearing 4 is connected to the lubrication pump. The first limit switch 9 and the second limit switch 10 are both installed on the side of the anchoring frame and are electrically connected to the lubrication pump respectively. The first limit switch 9 is triggered by rotating the handle when the anchoring plate is inserted into the anchoring pit. The second limit switch 10 is triggered by rotating the handle when the anchoring plate is removed from the anchoring pit.

[0027] During use, the activation of the first limit switch 9 indicates that the anchoring plate is in the anchoring pit and is in the anchored state. The activation of the second limit switch 10 indicates that the anchoring plate has been pulled out and is in the non-anchored state. Moving the anchoring plate from the anchored state to the non-anchored state, or vice versa, is an action that can be completed in 1-2 minutes. If the first limit switch 9 and the second limit switch 10 are not in contact for an extended period, it indicates that a problem has been encountered during the manual change of the anchoring plate's state. This is most likely due to insufficient or deteriorated lubricating oil, causing difficulty in rotation. In this case, the lubrication pump will be triggered to automatically add oil, resolving the hinge point jamming problem and facilitating use.

[0028] As attached Figure 3 and attached Figure 4 As shown, in another specific embodiment based on the above, the end of the rotating shaft 1 is perpendicularly connected to the rotating handle by a bolt in the same direction as the axial direction of the rotating shaft 1.

[0029] The aforementioned rotating shaft 1 has two threaded holes along the axial direction at its end. The rotating handle has an installation groove with a baffle inside. The baffle has two installation holes corresponding to the threaded holes. Two bolts pass through the corresponding installation holes and are threaded into the threaded holes of the rotating shaft 1.

[0030] The aforementioned bushings include a lubrication bushing 6 and a rotating handle bushing 8. An oil passage is provided on the lubrication bushing 6. The rotating handle bushing 8 is T-shaped and is slidably sleeved on the rotating shaft 1. The wide end of the T-shaped rotating handle bushing 8 is located on the side away from the anchor frame. The lubrication bushing 6 is slidably sleeved on the outside of the narrow end of the T-shaped rotating handle bushing 8. A spring 7 is connected between the side of the lubrication bushing 6 near the wide end of the T-shaped rotating handle bushing 8 and the wide end of the T-shaped rotating handle bushing 8. The spring 7 is used to provide a force that moves the lubrication bushing 6 and the rotating handle bushing 8 away from each other.

[0031] In this design, the position of the rotating handle relative to the anchor frame can be adjusted by regulating the distance between the two bolts and the rotating shaft 1. The anchor plate is hinged to the rotating handle, which effectively adjusts the distance between the anchor plate and the anchor frame. Thus, when the wheel deviates to one side of the track, the distance between the anchor plate and the anchor frame can be adjusted as needed, ensuring that both plates are positioned in the pit as much as possible. During this process, the spring 7 maintains support for the lubrication bushing 6 and the rotating handle bushing 8, thereby increasing the support between the rotating handle and the anchor frame and enhancing structural stability.

[0032] In another specific embodiment based on the above, a counterweight is provided at the end of the rotating handle away from the anchor plate. This facilitates the lifting of the anchor plate.

[0033] This utility model features a simple and practical structure. By using two separate anchoring devices, it increases the adjustment space and can accommodate situations where the wheels are biased to one side of the track, making it impossible to simultaneously lower the anchoring plates. At least one anchoring device is guaranteed to function, greatly ensuring the safety of the crane. The bearings used, such as bearing 4, can be standard products, making adjustment convenient and ensuring stable force distribution. The remaining components are simple to manufacture and widely applicable. Furthermore, the addition of a lubrication pump allows for automatic lubrication based on the limit state, reducing the workload of manual lubrication. This utility model has wide applicability, can be standardized, and is suitable for all cranes with counterweight-type trolley anchoring devices.

It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
