Description

Technical Field

[0001] The utility model relates to an automatic door of a logistics lift, in particular to a multi-interlocking linkage mechanism of the automatic door of a logistics lift. Background Art

[0002] The published Chinese utility model patent document CN202420134684.3 records a multi-door opening device, comprising a landing door lock (4) fixed on a landing door sill (3) and a first door ball (5) fixed on the landing door lock (4), and also comprising a linkage device (7) and a second door ball (6), wherein the linkage device (7) is fixed to the landing door lock (4), the number of the second door balls (6) is greater than or equal to 1, and the second door balls (6) are fixed on the linkage device (7).

[0003] The multi-door opening device of the above structure increases linkage devices and multiple door balls. The logistics elevator can make multiple stops on the same floor where it needs to stop. The door knife on the car door system can be used to link the floor door system to open and close the floor door panels. Stops at different positions can enable the logistics lines outside the floor station to connect with different compartments of the car in the logistics elevator. Each compartment can be used to transport goods reasonably and make overall use of them, which greatly improves the transportation efficiency.

[0004] At the same time, the above utility model states that the linkage device (7) includes a connecting rod (71), a base plate (72) and a fixed plate (73), the top end of the connecting rod (71) is fixed to the floor door lock (4), the lower part of the connecting rod (71) is fixed to the base plate (72), and the second door ball (6) is fixed to the base plate (72) and fixed to the connecting rod (71) through the fixed plate (73).

[0005] However, according to the text and drawings, the connecting rod in this structure is an integral design, extending straight from the landing door lock along the height of the landing door panel to the second door ball at the bottom. If the landing door panel is relatively large and the landing door lock is relatively far from the second door ball at the bottom, this design will result in the integral connecting rod being too long. This makes it difficult to precisely control the connecting rod's straightness tolerance during manufacturing to ensure that its size and shape meet the design requirements and achieve accurate assembly. Therefore, the manufacturing requirements for the connecting rod are high, and the product qualification rate is relatively difficult to control.

[0006] In addition, in its structure, the top end of the connecting rod is directly fixed to the side of the floor door lock close to the hook head. After the door knife clamps the first door ball or the second door ball, it needs to overcome the deadweight of the linkage device to drive the small ball on the first door ball to move to the right, thereby lifting the lock hook on the floor door lock. This will directly increase the load on the door motor, thereby increasing the energy consumption of the elevator operation.

[0007] In summary, the applicant believes that it is necessary to further optimize the structure of the above-mentioned linkage device, and therefore the applicant proposed the present utility model. Summary of the Invention

[0008] The purpose of the utility model is to solve the above-mentioned deficiencies in the prior art and to provide a multi-interlocking linkage mechanism for automatic doors of a logistics lift with a further optimized structure.

[0009] To achieve the above-mentioned purpose, the utility model is designed to provide a multi-interlocking linkage mechanism for an automatic door of a logistics elevator, comprising a lock hook assembly and a linkage mechanism, wherein the linkage mechanism comprises: an auxiliary door wheel assembly, a first connecting rod, and a second connecting rod; the second connecting rod is a multi-section structure comprising at least two rod segments, and each of the two rod segments is locked by at least two sets of bolt fastening assemblies having independent through-holes;

[0010] The movable door wheels and the fixed door wheels of the lock hook assembly and the auxiliary door wheel assembly are arranged linearly and spaced apart in the height direction of the floor door panel;

[0011] Connecting rods 1 are installed on both the lock hook assembly and the auxiliary door wheel assembly, and each of them rotates synchronously around the center of the fixed door wheel while its corresponding moving door wheel revolves around the center of the fixed door wheel;

[0012] All connecting rods 1 extend in the direction away from the lock hook head in the lock hook assembly until they are hinged to the same connecting rod 2, and drive the lock hook assembly or the movable door wheel of any auxiliary door wheel assembly to rotate around the center of its corresponding fixed door wheel through the door knife assembly, and synchronously drive the lock hook head in the lock hook assembly to rotate in the direction away from the lock block until it is completely unlocked.

[0013] The above-mentioned logistics elevator automatic door multi-interlocking linkage mechanism has a structure in which the connecting rod 2 is a multi-section structure. When the height of the floor door panel remains unchanged, the length of the single rod segment can be shortened. Therefore, when manufacturing the connecting rod, it is relatively easier to accurately control the straightness tolerance of the single rod segment of the connecting rod to ensure that its size and shape meet the design requirements. At the same time, this structural design only needs to select high-quality fixtures and positioning devices to ensure the stability and accuracy of the connecting rod segment during the processing, and then ensure the positioning accuracy of the through-hole openings on the rod segment. According to the "straight line axiom", the two rod segments are locked by at least two groups of independent bolt fastening components passing through the through holes. The two rod segments can be determined on a unique straight line, thereby achieving assembly accuracy.

[0014] In addition, in the above structure, all the connecting rods 1 on the lock hook assembly and the auxiliary door wheel assembly extend in the direction away from the lock hook head in the lock hook assembly until they are hinged to the same connecting rod 2, so that the connecting rod 2 is connected to the opposite side of the lock hook head on the lock hook assembly. When the door knife assembly drives the lock hook assembly or the movable door wheel of any auxiliary door wheel assembly to rotate around the center of its corresponding fixed door wheel, the lock hook head in the synchronous transmission lock hook assembly rotates in the direction away from the lock block until it is fully unlocked. There is no need to overcome the deadweight of the linkage mechanism, thereby achieving the purpose of reducing the operating load of the door motor, thereby reducing the energy consumption of the elevator operation.

[0015] In the above-mentioned multi-interlocking linkage mechanism of the automatic door of a logistics elevator, the through hole in its structure is preferably a waist-shaped hole, and extends straight in the height direction of the floor door panel.

[0016] The connecting rod 2 with a multi-section structure in the above-mentioned preferred technical solution has a total length of all its rod segments combined that can be adjusted within a certain range. When there is an error in the spacing between the connecting rods on the lock hook assembly and the auxiliary door wheel assembly, it is convenient to perform adaptive assembly by adjusting the total length of the connecting rod 2.

[0017] Compared with the prior art, the multi-interlocking linkage mechanism of the automatic door of a logistics elevator obtained by the present invention has the following technical effects:

[0018] The utility model provides a multi-interlocking linkage mechanism for the automatic door of a logistics elevator, which has a more rational structure. During manufacturing, the connecting rods in the structure are relatively easy to precisely control the straightness tolerance to ensure that their size and shape meet the design requirements, thereby achieving accurate assembly. In addition, when the door knife assembly drives the movable door wheel of the lock hook assembly or any auxiliary door wheel assembly to rotate around the center of its corresponding fixed door wheel, the lock hook head in the synchronous transmission lock hook assembly rotates in a direction away from the lock block until it is fully unlocked. This eliminates the need to overcome the deadweight of the linkage mechanism, reducing the operating load of the door motor and thus reducing the energy consumption of the elevator.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, as an embodiment of the present invention, a multi-interlocking linkage mechanism for an automatic door of a logistics elevator provided in this embodiment includes a lock hook assembly 1 and a linkage mechanism 2. The linkage mechanism 2 includes: an auxiliary door wheel assembly 3, two connecting rods 1 4 and a connecting rod 2 5; the connecting rod 2 5 is a multi-section structure, including two rod segments 6, and the two rod segments 6 are locked by two sets of bolt fastening assemblies 8 with independent through holes 7;

[0025] The locking hook assembly 1 and the movable door wheel 9 and the fixed door wheel 10 of the auxiliary door wheel assembly 3 are arranged linearly and spaced apart in the height direction of the floor door panel;

[0026] A connecting rod 4 is installed on both the lock hook assembly 1 and the auxiliary door wheel assembly 3, and each of them rotates synchronously around the center of the fixed door wheel 10 during the revolution of its corresponding moving door wheel 9 around the center of the fixed door wheel 10;

[0027] All connecting rods 1 4 extend in the direction away from the hook head 11 in the hook assembly 1 until they are hinged to different rod sections 6 of the same connecting rod 2 5, and drive the hook assembly 1 or the movable door wheel 9 of any auxiliary door wheel assembly 3 to rotate around the center of its corresponding fixed door wheel 10 through the door knife assembly, synchronously driving the hook head 11 in the hook assembly 1 to rotate in the direction away from the lock stop 12 until it is fully unlocked. Figure 3 shown.

[0028] like Figure 2 As shown, as another embodiment of the present invention, a multi-interlocking linkage mechanism for automatic doors of a logistics elevator provided in this embodiment has a general structure consistent with the aforementioned embodiment, but the linkage mechanism 2 in the structure of this embodiment includes: two auxiliary door wheel assemblies 3, three connecting rods 4 and one connecting rod 2 5; the connecting rod 2 5 is a multi-section structure, including three rod segments 6, and every two rod segments 6 are locked by two groups of independent bolt fastening assemblies 8 with through holes 7.

[0029] The through holes 7 described in all the above embodiments are waist-shaped holes and extend straight in the height direction of the floor door panel, so that the total length of all the rod sections 6 combined together can be adjusted within a certain range. When there is an error in the spacing distance between the lock hook assembly 1 and the connecting rod 1 4 on the auxiliary door wheel assembly 3, it is convenient to perform adaptive assembly by adjusting the total length of the connecting rod 2 5.

[0030] The above-mentioned logistics elevator automatic door multi-interlock linkage mechanism has a structure in which the connecting rod 2 5 is a multi-section structure. When the height of the floor door panel remains unchanged, the length of the single rod segment 6 can be shortened, and thus when manufacturing the connecting rod, it is relatively easier to accurately control the straightness tolerance of the single rod segment 6 of the connecting rod to ensure that its size and shape meet the design requirements. At the same time, this structural design only needs to select high-quality fixtures and positioning devices to ensure the stability and accuracy of the connecting rod segment 6 during the processing process, and then ensure the positioning accuracy of the through hole 7 on the rod segment 6. Then, according to the "straight line axiom", that is, the two rod segments 6 are locked by at least two groups of independent bolt fastening assemblies 8 passing through the through holes 7, the two rod segments 6 can be determined to be on a unique straight line, thereby achieving assembly accuracy.

[0031] In addition, in the above structure, all connecting rods 1 4 on the lock hook assembly 1 and the auxiliary door wheel assembly 3 extend in the direction away from the lock hook head 11 in the lock hook assembly 1 until they are hinged to the same connecting rod 2 5, so that the connecting rod 2 5 is connected to the opposite side of the lock hook head 11 on the lock hook assembly 1, and the door knife assembly drives the lock hook assembly 1 or the movable door wheel 9 of any auxiliary door wheel assembly 3 to rotate around the center of its corresponding fixed door wheel 10, and the lock hook head 11 in the synchronous transmission lock hook assembly 1 rotates in the direction away from the lock block until it is fully unlocked. There is no need to overcome the deadweight of the linkage mechanism 2, thereby achieving the purpose of reducing the operating load of the door motor, thereby reducing the energy consumption of the elevator operation.

[0032] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention.
