A mechanical locking structure for vehicles

Abstract

This invention discloses a mechanical locking structure for a traveling crane, comprising a pull rod box, a pull rope, and a cooperating pin component and a positioning groove. The pin component is installed on the traveling crane frame or the traveling crane guide rail, and the positioning groove is correspondingly disposed on the traveling crane guide rail or the traveling crane frame. The two ends of the pull rope are respectively connected to the pull rod box and the pin component, thereby enabling remote control of the pin component via the pull rod box to disengage or engage with the positioning groove. When the traveling crane frame is stationary, the pin component can be remotely controlled via the pull rod box to engage with the positioning groove, thus mechanically locking the traveling crane frame onto the traveling crane guide rail, preventing the traveling crane frame from slipping relative to the traveling crane guide rail, ensuring stable parking of the traveling crane frame, and improving safety performance.

Description

Technical Field

[0001] This application relates to the field of marine machinery technology, and in particular to a crane machinery locking structure. Background Technology

[0002] To facilitate the transfer of heavy equipment or cargo on ships, ships are usually equipped with overhead cranes. Existing overhead cranes consist of guide rails and a crane frame mounted on the guide rails. A crane is installed on the crane frame, and by driving the crane frame to slide along the guide rails, the function of transferring heavy objects lifted by the crane is realized.

[0003] During loading and unloading of heavy objects or when the crane is not in use, in order to prevent the crane frame from slipping relative to the guide rail, the existing crane frame is generally equipped with a braking mechanism. However, the existing braking mechanisms on the crane are all friction type. During use, due to changes in friction and the influence of complex conditions such as wind, waves and swaying on the ship, the brakes are prone to failure, which poses a significant safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a mechanical locking structure for vehicles that can solve the aforementioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A mechanical locking structure for a crane includes a pull rod case, a pull rope, and a cooperating pin component and a positioning groove. The pin component is installed on the crane frame or the crane guide rail, and the positioning groove is correspondingly disposed on the crane guide rail or the crane frame. The two ends of the pull rope are respectively connected to the pull rod case and the pin component, thereby enabling remote control of the pin component through the pull rod case, causing the pin component to disengage from or engage with the positioning groove.

[0007] Optionally, it also includes a reversing component, wherein the pin component is connected to the pull rope through the reversing component, and by pulling the pull rope, the reversing component drives the pin component to extend and engage with the positioning groove.

[0008] Optionally, the pin component includes a pin body and a return spring, the return spring being sleeved on the pin body, and the pin body being pushed out of the positioning groove by the return spring.

[0009] Optionally, the reversing component includes a rocker arm and a hinge support. The hinge support is fixedly installed, and the middle part of the rocker arm is hinged to the hinge support. One end of the rocker arm is provided with a sliding hole. The pin component is slidably connected to the sliding hole through a sliding pin. The pull rope is connected to the end of the rocker arm away from the sliding hole.

[0010] Optionally, the reversing component includes a reversing fixed pulley, which is movably connected, and the pull rope passes around the reversing fixed pulley and is connected to the pin component.

[0011] Optionally, the trolley case includes a case body, a pull rod, and a locking component. One end of the pull rod is hinged to the case body, and the other end extends to the outside of the case body. The pull rope extends into the case body and is connected to the pull rod. The locking component is used to lock the pull rod, so that the pin component remains engaged with the positioning groove.

[0012] Optionally, the trolley case also includes an electronically controlled switch disposed inside the case. When the trolley pulls the pull rope to engage the pin component with the positioning groove, the trolley triggers the electronically controlled switch.

[0013] Optionally, the pin component is mounted on the crane frame, and a plurality of positioning grooves are arranged at intervals along the length of the crane guide rail.

[0014] Optionally, the suitcase further includes a tensioner disposed within the suitcase body. The pull rod is provided with a release clamping structure, and the pull rope passes through the release clamping structure and is connected to the tensioner. When the release clamping structure releases the pull rope, the tensioner pulls the pull rope to keep it in a taut state. When the release clamping structure clamps the pull rope, the pull rod can pull the pull rope to move.

[0015] Optionally, the pull rod includes a first clamping arm and a second clamping arm. The first clamping arm has a hinged end and a first clamping end, and the second clamping arm has a handheld end and a second clamping end. The hinged end is hinged to the inner wall of the box. The release mechanism includes the first clamping end and the second clamping end arranged opposite to each other, and the handheld end extends to the outside of the box. A first connecting rod is provided on the top side of the first clamping arm, and a second connecting rod is provided on the top side of the second clamping arm. The first connecting rod and the second connecting rod are hinged together, so that when the handheld end is pushed upward, the release mechanism releases the pull rope, and when the handheld end is pushed downward, the release mechanism clamps the pull rope.

[0016] The beneficial effects of this application are as follows: This invention provides a mechanical locking structure for a traveling crane. When the traveling crane frame is parked, a latch component can be remotely controlled via a pull-rod box to engage with the positioning slot, thereby mechanically locking the traveling crane frame onto the traveling crane guide rail. This prevents the traveling crane frame from slipping relative to the traveling crane guide rail, ensuring stable parking and improving safety performance. When it is necessary to move the traveling crane frame, the latch component can also be remotely controlled via the pull-rod box to disengage from the positioning slot. In this solution, the pull-rod box is connected to the latch component at a higher position via a pull rope. The pull-rod box can be placed on the ground in a location convenient for manual control. When manually controlling the latch component, there is no need to climb to a higher position; it can be done simply by standing on the ground. Moreover, the structure is a purely mechanical transmission structure, eliminating the need for electrical controls. This facilitates manual operation while ensuring the reliability of the mechanical locking structure. Attached Figure Description

[0029] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] like Figure 1As shown, this embodiment provides a mechanical locking structure for a crane, including a pull rod box 3, a pull rope 2, and a mutually cooperating pin component 1 and a positioning groove 4. The pin component 1 is installed on the crane frame 100 or the crane guide rail 200, and the positioning groove 4 is correspondingly disposed on the crane guide rail 200 or the crane frame 100. The two ends of the pull rope 2 are respectively connected to the pull rod box 3 and the pin component 1, thereby realizing remote control of the pin component 1 through the pull rod box 3, so that the pin component 1 can disengage from or engage with the positioning groove 4.

[0033] The positioning groove 4 can be a through groove or a blind groove. It can be formed by excavating directly on the crane guide rail 200 or the crane frame 100, or by adding a plate with the positioning groove 4 to the side of the crane guide rail 200 or inside the crane frame 100 to achieve the setting purpose.

[0034] The existing crane frame 100 is generally set at a high position, making it difficult for ground personnel to directly operate the high-mounted pin component 1. Therefore, this solution connects the pin component 1 to a remote lever box 3 via a pull rope 2. The lever box 3 can be set at a position close to the ground. When the lever box 3 is pulled, the pin component 1 can be moved by pulling the pull rope 2, allowing the pin component 1 to move out of or engage with the positioning slot 4, thereby realizing the function of remote control.

[0035] In practical applications, several wire clamps 6 can be installed on the crane support used to install the crane guide rail 200. By passing the pull rope 2 through each wire clamp 6, the pull rope 2 can be routed close to the surface of the crane support, thus avoiding the problem of the pull rope 2 being suspended in the air and affecting the hoisting operation.

[0036] Based on the mechanical locking structure of the crane in this embodiment, when the crane frame 100 is parked, the latch component 1 can be remotely controlled by the pull-rod box 3 to engage with the positioning slot 4, thereby mechanically locking the crane frame 100 onto the crane guide rail 200, preventing the crane frame 100 from sliding relative to the crane guide rail 200, ensuring the stability of the crane frame 100 at rest, and improving safety performance. When it is necessary to move the crane frame 100, the latch component 1 can also be remotely controlled by the pull-rod box 3 to disengage from the positioning slot 4. In this solution, the pull-rod box 3 is connected to the latch component 1 at a higher position by a pull rope. The pull-rod box 3 can be set at a convenient location on the ground for manual control. When manually controlling the latch component 1, there is no need to climb to a higher position; it can be done simply by standing on the ground. Moreover, the structure is a purely mechanical transmission structure, eliminating the need for electrical controls. While facilitating manual operation, this ensures the reliability of the mechanical locking structure of this solution.

[0037] The pull rope 2 is a flexible connector that can only apply tension to the pin component 1 but cannot apply thrust. In order to avoid interference, when the pin component 1 is mounted on the crane frame 100, the pull rope 2 can only be connected to the pin component 1 on the crane frame 100 and then extend upward relative to the pin component 1; when the pin component 1 is mounted on the crane guide rail 200, the pull rope 2 can only be connected to the pin component 1 on the crane guide rail 200 and then extend downward relative to the pin component 1.

[0038] Therefore, in order to enable the pin component 1 to engage with the positioning groove 4 when the tension rope 2 is manually applied, the crane mechanical locking structure of this embodiment also includes a reversing component 5. The pin component 1 is connected to the tension rope 2 through the reversing component 5. By pulling the tension rope 2, the reversing component 5 is driven to extend the pin component 1 to engage with the positioning groove 4.

[0039] by Figure 1 Taking the structure shown as an example, when the pull box 3 is pressed down, the pull rope 2 is pulled and tightened. One end of the pull rope 2 connected to the reversing component 5 is pulled upward. At this time, under the transmission of the reversing component 5, the pin component 1 extends downward and engages with the positioning groove 4, thereby achieving the purpose of mechanically locking the crane frame 100. The locking achieved by pressing down the pull box 3 is exactly in line with the conventional operating logic.

[0040] To ensure that the pin body 11 can automatically disengage from the positioning groove 4 after the pull rope 2 is released, further refer to... Figure 3 The pin component 1 includes a pin body 11 and a return spring 12. The return spring 12 is sleeved on the outside of the pin body 11, and the pin body 11 is pushed away from the positioning groove 4 by the return spring 12.

[0041] That is, at this time, the return spring 12 always provides a pushing force to the pin body 11 to move in the direction of disengaging from the positioning groove 4. When the pull box 3 is released, the pull rope 2 loses the tension on the reversing component 5. Under the action of the return spring 12, it will push the pin body 11 to move in the direction of disengaging from the positioning groove 4, thereby realizing the function of automatic release.

[0042] Furthermore, refer to Figure 3 The pin component 1 also includes a pin support 13, through which the pin body 11 passes. The return spring 12 is installed inside the pin support 13. The pin support 13 provides a reliable limit for the mating connection between the pin body 11 and the return spring 12. At the same time, the pin support 13 can guide the axial movement of the pin body 11, preventing the pin body 11 from tilting or shifting.

[0043] In another embodiment, the return spring 12 can also be configured to always provide a pushing force to the pin body 11 in the direction of the locking positioning groove 4. That is, after the pull case 3 is released, the pull rope 2 loses its tension on the pin body 11, and the return spring 12 pushes the pin body 11 to engage with the positioning groove 4. At the same time, in this method, there is no need to set up a reversing component 5. The pull rope 2 can be directly connected to the pin body 11. When the pull case 3 is pressed down, the pull rope 2 pulls the pin body 11 away from the positioning groove 4 to unlock.

[0044] Regarding the arrangement of the reversing component 5, in one embodiment, refer to... Figure 2-3 The reversing component 5 includes a rocker arm 52 and a hinge support 51. The hinge support 51 is fixedly installed. The middle part of the rocker arm 52 is hinged to the hinge support 51. One end of the rocker arm 52 is provided with a sliding hole 521. The pin component 1 is slidably connected to the sliding hole 521 through a sliding pin 14. The pull rope 2 is connected to the end of the rocker arm 52 away from the sliding hole 521.

[0045] by Figure 3 To illustrate, when the pull rope 2 pulls the rocker arm 52 upward, one end of the rocker arm 52 connected to the pin component 1 will swing downward, thereby pressing the pin component 1 downward through the sliding pin 14, so that the pin component 1 can extend downward to engage with the positioning groove 4.

[0046] Regarding the arrangement of the reversing component 5, in another embodiment, refer to... Figure 5 The reversing component 5 includes a reversing fixed pulley 53, which is movably connected to the pull rope 2, which passes around the reversing fixed pulley 53 and is connected to the pin component 1.

[0047] Specifically, the reversing pulley 53 has the function of changing the direction of the pulling force, so as to... Figure 5 As shown in the diagram, when the pull rope 2 is pulled upward, it will pull the pin component 1 downward, so that the pin component 1 can extend downward to engage with the positioning groove 4.

[0048] Regarding the structure of suitcase 3, please refer to... Figure 4 or Figure 6 The trolley case 3 includes a case body 31, a pull rod 32, and a locking member 37. One end of the pull rod 32 is hinged inside the case body 31, and the other end extends outside the case body 31. The pull rope 2 extends into the case body 31 and is connected to the pull rod 32. The locking member 37 is used to lock the pull rod 32, so that the pin member 1 is engaged with the positioning groove 4.

[0049] Under the action of the return spring 12, the pin body 11 always tends to disengage from the positioning groove 4. When the pull rod 32 is pressed down by hand to pull the pin component 1 into engagement, if the hand is released, the pin body 11 will return to the disengaged state. Therefore, this solution provides a locking component 37 in the pull rod box 3. After the pull rod 32 is pressed down to engage the pin component 1 with the positioning groove 4, the pull rod 32 can be locked directly by the locking component 37. This avoids the problem of the pin body 11 freely resetting under the elastic force of the return spring 12, thereby achieving reliable locking of the crane frame 100.

[0050] In one embodiment, the trolley case 3 further includes an electronic control switch 33 disposed within the case body 31. When the trolley 32 pulls the pull rope 2 to engage the pin component 1 with the positioning groove 4, the trolley 32 triggers the electronic control switch 33.

[0051] Specifically, the electric control switch 33 can be a push-button type or an inductive type limit switch. The electric control switch 33 can be connected to the vehicle control system and interlocked with the start of the vehicle. When the electric control switch 33 is triggered, it indicates that the pin component 1 and the positioning groove 4 are in a locked state, and the vehicle system is forcibly locked. Even if the system receives a start command from the operating terminal, it will not start the vehicle, thereby avoiding mechanical failure caused by human starting the vehicle under mechanical locking.

[0052] Furthermore, an indicator light 34 connected to the electric control switch 33 can be installed on the rolling case 3. When the electric control switch 33 is triggered, the indicator light 34 will light up, indicating to the staff that the crane frame 100 is in a mechanically locked state.

[0053] In a preferred embodiment, the pin component 1 is mounted on the crane frame 100, and a plurality of positioning grooves 4 are arranged at intervals along the length direction of the crane guide rail 200.

[0054] Multiple positioning slots 4 are arranged on the crane guide rail 200, which can fix the crane frame 100 in multiple positions and meet the requirement of locking the crane frame 100 in any position.

[0055] In one embodiment, the trolley case 3 is fixedly installed at a certain position on the ground. Since the pin component 1 installed on the trolley frame 100 will move with the trolley frame 100, the length of the pull rope 2 will also move accordingly. Therefore, the total length of the pull rope 2 must meet the requirement that the pin component 1 and the trolley case 3 can still be connected when the trolley frame 100 is furthest away from the trolley case 3. However, if the longest pull rope 2 is used directly, the pull rope 2 will gradually loosen when the trolley frame 100 moves closer to the trolley case 3. At this time, there is a problem that the pull rod 32 cannot move the pin component 1 by pulling the pull rope 2 within the movable range.

[0056] To solve the above problems, refer to Figure 6-9 In one embodiment, the trolley case 3 further includes a tensioner 35 disposed within the case body 31. The pull rod 32 is provided with a release clamping structure. The pull rope 2 passes through the release clamping structure and is connected to the tensioner 35. When the release clamping structure releases the pull rope 2, the tensioner 35 pulls the pull rope 2 to keep the pull rope 2 always in a taut state. When the release clamping structure clamps the pull rope 2, the pull rod 32 can pull the pull rope 2 to move.

[0057] Specifically, the tensioner 35 has the function of automatically tightening the pull rope 2. It can be a structure including a roller and a spring. The center of the spring is connected to the roller, and the pull rope 2 is wound on the roller. When the crane frame 100 moves away, the pull rope 2 is continuously released from the roller, and the spring gradually tightens. When the crane frame 100 moves closer, under the elastic force of the spring, the roller automatically winds up the pull rope 2, thereby achieving the purpose of automatically tightening the pull rope 2.

[0058] Based on the above structure, when it is necessary to move the overhead crane frame 100, refer to... Figure 6 When the pull rod 32 is raised, the clamping mechanism is in a relaxed state, and the pull rope 2 can move freely relative to the pull rod 32. At this time, the crane frame 100 can move freely along the crane guide rail 200. When it is necessary to lock the crane frame 100, refer to... Figure 7 When the pin body 11 is aligned with a certain positioning groove 4 on the crane guide rail 200, the pull rope 2 is clamped by the loose clamping structure and the pull rod 32 is pressed down. The pull rod 32 pressed down in the clamped state can pull the tensioned pull rope 2, and the pull rope 2 pulls the pin body 11 to lock the crane frame 100.

[0059] Therefore, the above embodiments can meet the requirement that the trolley case 3 fixed on the ground can always maintain effective control over the latch component 1.

[0060] Furthermore, regarding the setting of the release-clamp structure, in one embodiment, the pull rod 32 includes a first clamping arm 321 and a second clamping arm 322. The first clamping arm 321 has a hinged end 3211 and a first clamping end 3212 facing each other, and the second clamping arm 322 has a handheld end 3221 and a clamping end 3222 facing each other. The hinged end 3211 is hinged to the inner wall of the housing 31. The release-clamp structure includes the first clamping end 3212 and the second clamping end 3222 facing each other. The handheld end 3221 extends to the outside of the housing 31. A first connecting rod 3213 is provided on the top side of the first clamping arm 321, and a second connecting rod 3223 is provided on the top side of the second clamping arm 322. The first connecting rod 3213 and the second connecting rod 3223 are hinged together, so that when the handheld end 3221 is pushed upward, the release-clamp structure releases the pull rope 2, and when the handheld end 3221 is pushed downward, the release-clamp structure clamps the pull rope 2.

[0061] That is, the pull rod 32 is configured as a structure with two connected sections: a first clamping arm 321 and a second clamping arm 322. Relative rotation of the first clamping arm 321 and the second clamping arm 322 adjusts the distance between the first clamping end 3212 and the second clamping end 3222, thereby achieving the function of clamping and releasing the pull rope 2. Furthermore, it can clamp the pull rope 2 while pressing down on the pull rod 32, and automatically release the pull rope 2 when the pull rod 32 is raised, eliminating the need for complicated operations. Therefore, this solution has the advantages of simple structure and convenient operation.

[0062] Furthermore, a torsion spring 36 is provided at the hinge end 3211 of the first clamping arm 321. The torsion spring 36 is based on the torque of the first clamping arm 321 rotating upward. Based on this torque, when the second clamping arm 322 is pressed down, the first clamping end 3212 can clamp with the second clamping end 3222, ensuring that a reliable clamping force can be applied to the pull rope 2 when the pull rod 32 is pressed down.

[0063] Furthermore, a wire fixing hole 3214 is provided on the first clamping end 3212 of the first clamping arm 321. The pull rope 2 passes through the wire fixing hole 3214. The wire fixing hole 3214 can be used to limit the pull rope 2 and prevent the pull rope 2 from leaving the clamping range of the loosening clamping structure.

[0064] Combination Figure 6-9The second clamping arm 322 includes a first arm 3224, a second arm 3225, and a third arm 3226 that are hinged in sequence. When the first arm 3224, the second arm 3225, and the third arm 3226 are rotated to the same plane, the pull rod 32 can swing freely up and down relative to the box body 31. A slot 311 is provided on one side of the box body 31. When the pull rod 32 is pushed down until the pin component 1 is locked with the positioning slot 4, the second arm 3225 is rotated laterally relative to the first arm 3224 so that the second arm 3225 is locked into the slot 311. Then the third arm 3226 is rotated upward so that the third arm 3226 is locked with the locking component 37, thereby locking the pull rod 32 and preventing the pull rope 2 from moving freely.

[0065] In another embodiment, a downwardly extending mounting bracket can be installed on the side of the crane frame 100, and the trolley case 3 can be directly installed on the mounting bracket to meet the requirement of installing the trolley case 3 close to the ground; at the same time, when the crane frame 100 moves, it will drive the mounting bracket to move, and then drive the trolley case 3 to move accordingly. Throughout the process, the trolley case 3 and the pin component 1 always remain relatively stationary, so there is no need to consider the problem of the pull rope 2 being stretched.
