Description

Technical Field

[0001] The utility model particularly relates to a safety tongs transmission mechanism. Background Art

[0002] With the development of the Internet and people's increasingly improved lives, people's demand for online shopping is gradually increasing. Online shopping is inseparable from the logistics of goods. Warehouse management, as the first step of logistics, is also very important. In modern warehouse management, in order to solve the problem of efficient warehouse management of goods within the specified space, people have introduced shelves. Shelves are like databases, which can reasonably distinguish and store goods. Stackers, which play a role similar to porters in the database, can efficiently and effectively pick up and transport goods from the shelves. In order to enable stackers to transfer more goods, designers have designed double-column stackers. Double-column stackers can efficiently transfer heavier goods. At this time, the safety of the cargo is also a problem to be considered. The existing double-column stacker is provided with safety clamps on both sides, and each safety clamp is provided with an independent transmission structure. When there is a special situation, the safety clamp is emergency stopped and clamped on the guide rail under the control of the speed limiter; however, since the two transmission methods are independent, the operator can only control a single safety clamp to perform the braking operation in an emergency. Since the cargo on the loading platform may be heavy, if only the safety clamp on one side can be started, the safety clamp on this end will be severely worn, and the braking effect is not ideal.

[0040] Furthermore, a limiting groove 800 for the transmission connecting rod 81 to pass through is formed on the reset fixing plate 83 .

[0041] The working principle of the utility model is:

[0042] by Figure 1 As shown, the structure of the stacker includes a loading platform 5, a side plate 511 in the side frame, and a fork 52; these belong to the conventional design of the stacker, so the working principle thereof will not be described in detail. When the stacker encounters an emergency and needs to be stopped urgently, the speed limiter sends a signal and pulls the steel cable 68. In order to better illustrate the design principle of the present application, one linkage is defined as the A linkage, and the other linkage is defined as the B linkage. As an embodiment 1, the safety clamp 9 is respectively set on the side plate 511 in the side frame, and the steel cable 68 is set on the A linkage, so when the steel cable 68 is pulled, the A linkage will be linked, and a swing component is rotatably arranged between the A linkage and the B linkage. When the A linkage moves, the swing component will be linked, and the swing component is rotatably arranged with the B linkage, so the B linkage will be linked, and the A linkage and the B linkage are respectively provided with safety clamps 9, and the steel cable 68 is pulled to link the A linkage and the B linkage so that the two safety clamps 9 simultaneously hold the elevator guide rail 31.

[0043] In the above technology, as Example 1, the A linkage member and the B linkage member can be set to the following structure: taking the steel cable 68 set on the A linkage member as an example, when the steel cable 68 is pulled upward to link the linkage lever 71, the linkage lever 71 drives the linkage shaft 73 to rotate, and the linkage shaft 73 is provided with a gear 731, and the gear 731 is meshed with a fixed rack 751; when the linkage shaft 73 rotates, the fixed rack 751 moves upward during the meshing process with the gear 731, and since the fixed rack 751 is set on the jacking block 75, the jacking block 75 will also move upward, and the brush body 92 of the safety clamp 9 is set on the jacking block 75, and the safety clamp seat 91 is set on the side plate 511 in the side frame, so the safety clamp seat 91 will not move, and the brush body 92 will move along the movable groove 93 on the safety clamp seat 91. As Example 1, when the movable groove 93 is set as Figure 8 When the longitudinal section shown is a trapezoidal structure, the distance between the two brush bodies 92 will decrease during the upward movement of the brush body 92 until the two brush bodies 92 hold the elevator guide rail 31 tightly. The linkage lever 71 is also provided with a transmission link 81, so the linkage lever 71 will also move upward in conjunction with the transmission link 81 during the movement, and the transmission link 81 is also provided with an arm 86 for rotation. During the rotation of the arm 86, the end of the swing lever close to the A linkage member will be driven to move upward, while the end of the swing lever close to the B linkage member will move downward. At this time, the swing lever will drive the arm 86 on the B linkage member to rotate, and the arm 86 will drive the transmission link 81 on the B linkage member to move upward during the rotation. Consistent with the above principle, during the upward movement of the transmission link 81, the linkage shaft 73 will be driven to rotate, thereby driving the lifting block 75 and the brush body 92 of the safety clamp 9 to move upward. When the brush body 92 of the safety clamp 9 needs to be moved downward, the steel cable 68 is pulled downward, and the working principle is consistent with the above. That is to say, by pulling the steel cable 68, the two safety clamps 9 can be driven to hold the elevator guide rail 31 at the same time.

[0044] In the above technology, a reset fixing plate 83 is movably arranged on the transmission link 81, and a limiting groove 800 is opened on the reset fixing plate 83 for the transmission link 81 to pass through. In a specific installation, the reset fixing plate 83 can be installed on the side plate in the side frame. When the transmission link 81 is pulled, the reset fixing plate 83 does not move, and the transmission link 81 passes through the limiting groove 800 and moves up and down. In order to prevent the transmission link 81 from escaping from the limiting groove 800 during movement, a nut 80 is also arranged on the transmission link 81. A spring 812 is sleeved on the transmission link 81 between the nut 80 and the reset fixing plate 83, so when the transmission link 81 moves upward, the spring 812 will produce a compressed deformation; when the transmission link 81 moves downward, the spring 812 will restore the deformation.

[0045] In the above technology, the swing arm can be configured as a first swing arm 87 and a second swing arm 871 , and the first swing arm 87 and the second swing arm 871 are connected by a basket bolt 88 .

[0046] In the above technology, a hinge seat lever 841 may be fixedly provided on the stacker, so that the arm 86 rotates around the hinge seat lever 841 under the action of an external force, and the arm 86 is preferably provided in an L-shaped structure.

[0047] The present application uses structures such as a steel cable linkage linkage member and a swing assembly to link the two safety clamps 9 to tightly hold the elevator guide rails 31, thereby effectively reducing the wear of the safety clamps 9.

[0048] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
