Description

Technical Field

[0001] The invention belongs to the technical field of automated transportation, and in particular relates to a locking mechanism of a planar double-slider linkage. Background Art

[0002] The vertical transport module is an important part of an automated transfer device, which is used to realize the vertical transfer of certain goods between the ship's warehouse and the deck. When the vertical transport module table rises to a position flush with the deck surface, it must be reliably locked through a locking mechanism to ensure that it can withstand the pressure load generated when the vehicle moves on the deck surface. When not in working state, the seal between the table and the deck also needs to be achieved with the help of a locking mechanism and a sealing ring.

[0003] At present, the locking mechanism is driven by hydraulic power and arranged on the hull hatch coaming structure. It cannot be integrated on the vertical transport module, has many installation interfaces, and the on-site installation and debugging processes are relatively complicated. The degree of modularization of the equipment is low. At the same time, it needs to be equipped with a hydraulic pump station and hydraulic pipelines, which are prone to leakage and pollute the ship environment.

[0004] Therefore, how to improve a locking mechanism with a planar double-slider linkage to solve the problems of the existing vertical transport module locking mechanism having multiple installation interfaces, complex on-site installation and debugging processes, and low degree of equipment modularization has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The embodiment of the present invention provides a locking mechanism with a planar double-slider linkage, which can solve the problems of the existing vertical transport module locking mechanism having many installation interfaces, complex on-site installation and debugging processes, and low degree of equipment modularization.

[0006] In an embodiment of the present invention, a locking mechanism with two planar sliders linked to each other is provided, comprising: a driving rod 1, an electric push rod 2, a guide seat 3, a locking pin 4, a connecting rod structure 5, a guide rail 6 and a slider 7.

[0007] The slider 7 is mounted on the body of the driving rod 1 , the tail of the driving rod 1 is connected to the electric push rod 2 , and the plurality of locking pins 4 are connected to the driving rod 1 through connecting rod structures 5 .

[0008] The locking pin 4 is installed in the guide seat 3, and the guide seat 3 and the guide rail 6 are both fixed on the table base of the lifting platform.

[0009] Furthermore, the locking mechanism comprises:

[0010] The driving rod 1 is driven by the electric push rod 2 , and the slide block 7 moves back and forth in the guide rail 6 .

[0011] Furthermore, when the driven rod 1 moves, the connecting rod structure 5 drives the multiple sets of locking pins 4 to move in linkage;

[0012] The locking pin 4 is limited by the guide seat 3, and is extended and retracted perpendicular to the movement direction of the driving rod 1, and cooperates with the slot on the deck sill to complete the locking and unlocking of the table top.

[0013] Further, the locking structure comprises: an electric cylinder;

[0014] The electric cylinder is arranged along the direction of the driving rod 1 . When the electric cylinder pushes the driving rod 1 to move, the multiple connecting rod structures 5 drive the locking pin 4 to move simultaneously, and the locking pin 4 moves forward and backward in the guide seat 3 .

[0015] Furthermore, the guide seat 3 and the locking pin 4 are symmetrically distributed on both sides of the guide rail 6 .

[0016] Furthermore, the number of the guide seats 3 and the number of the locking pins 4 are 8 respectively.

[0017] The beneficial effects brought by the present invention are as follows:

[0018] It can be seen from the above scheme that an embodiment of the present invention provides a locking mechanism with a planar double-slider linkage, including: a driving rod, an electric push rod, a guide seat, a locking pin, a connecting rod structure, a guide rail and a slider.

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In order to solve the problems of the existing vertical transport module locking mechanism with multiple installation interfaces, complex on-site installation and debugging processes, and low modularization of the equipment, the present invention provides a planar double-slider linkage locking mechanism. The technical solution of the present invention uses an electric cylinder as a power to drive multiple groups of slider mechanisms to move simultaneously. Only one power device is required to achieve the synchronous action of multiple groups of locking mechanisms. It occupies a small space and can be flexibly arranged inside the vertical transport module table structure. The equipment is highly modularized and has better on-site assembly processability.

[0025] like Figures 1 to 3 As shown, Figure 1 A first structural schematic diagram showing a planar double-slider linkage locking mechanism according to an embodiment of the present invention, Figure 2 A schematic diagram showing the structure of a guide seat and a connecting rod of a locking mechanism with two planar sliders linked to each other according to an embodiment of the present invention is shown. Figure 3 A second structural schematic diagram of a planar double-slider linkage locking mechanism according to an embodiment of the present invention is shown.

[0026] In the figure, a locking mechanism with two planar sliders linked together includes: a driving rod 1, an electric push rod 2, a guide seat 3, a locking pin 4, a connecting rod structure 5, a guide rail 6 and a slider 7.

[0027] The slider 7 is mounted on the body of the driving rod 1 , the tail of the driving rod 1 is connected to the electric push rod 2 , and the plurality of locking pins 4 are connected to the driving rod 1 through connecting rod structures 5 .

[0028] The locking pin 4 is installed in the guide seat 3, and the guide seat 3 and the guide rail 6 are both fixed on the table base of the lifting platform.

[0029] In one embodiment of the present invention, the locking mechanism comprises:

[0030] The driving rod 1 is driven by the electric push rod 2 , and the slide block 7 moves back and forth in the guide rail 6 .

[0031] In one embodiment of the present invention, when the driven rod 1 moves, the connecting rod structure 5 drives multiple sets of locking pins 4 to move in linkage;

[0032] The locking pin 4 is limited by the guide seat 3, and is extended and retracted perpendicular to the movement direction of the driving rod 1, and cooperates with the slot on the deck sill to complete the locking and unlocking of the table top.

[0033] In one embodiment of the present invention, the locking structure comprises: an electric cylinder;

[0034] The electric cylinder is arranged along the direction of the driving rod 1 . When the electric cylinder pushes the driving rod 1 to move, the multiple connecting rod structures 5 drive the locking pin 4 to move simultaneously, and the locking pin 4 moves forward and backward in the guide seat 3 .

[0035] In one embodiment of the present invention, the guide seat 3 and the locking pin 4 are symmetrically distributed on both sides of the guide rail 6 .

[0036] In one embodiment of the present invention, the number of the guide seats 3 and the number of the locking pins 4 are 8 respectively.

[0037] It is understandable that in other implementations of the embodiments of the present invention, the number of guide seats 3 and locking pins 4 can be further adjusted according to specific needs, and the specific number is not specifically limited here.

[0038] In one embodiment of the present invention, a guide slider is installed on the driving rod of a planar double-slider linkage locking mechanism, which can cooperate with the guide rail on the table base to make the driving rod move forward and backward. The driving rod is connected to the connecting rod through a pin shaft; the connecting rod is connected to the locking pin through a pin shaft, and the locking pin is installed in a guide seat, and the guide seat is fixed on the table base. An electric cylinder is arranged along the direction of the driving rod. When the electric cylinder pushes the driving rod to move, multiple groups of connecting rods drive the locking pins to move simultaneously, and the locking pins move forward and backward in the guide seat to achieve the locking and unlocking functions.

[0039] The technical solution of the present invention only requires one power device to realize the synchronous action of multiple locking mechanisms, occupies a small space, can be flexibly arranged inside the vertical transport module table structure, has a higher degree of equipment modularization, and better assembly processability.

[0042] The driving rod 1 is driven by the electric push rod 2 and can move forward and backward in the guide rail 6 through the slider 7. When the driving rod 1 moves, it will drive multiple sets of locking pins 4 to work together through the connecting rod 5. Since the locking pins 4 are limited by the guide seat 3, they are extended and retracted perpendicular to the movement direction of the driving rod, and cooperate with the slots on the deck sill to complete the locking and unlocking of the table top.

[0043] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
