Description

Technical Field

[0001] The utility model relates to a vertical lifting mechanism, in particular to a vertical lifting mechanism with a ceiling rail. Background Art

[0002] In order to speed up the efficiency of goods entering and leaving the warehouse, a cargo transportation mechanism is usually set up in the warehouse to realize quick retrieval and quick release of goods. The cargo transportation mechanism currently used usually adopts a chain transmission method to achieve lifting and lowering. With the long-term use of the cargo transportation mechanism, the transmission chain will become longer due to wear, which will cause the transmission chain to be unable to be in a tensioned state during the cargo handling process, thereby affecting the meshing state between the sprockets of the transmission chain, that is, there will be no meshing transmission between the transmission chain and the sprocket, thereby affecting the stability of the cargo handling process. Utility Model Content

[0003] In order to solve the problems in the related art, the present application provides a vertical lifting mechanism with a ceiling rail, which solves the problem of unbalanced cargo handling caused by loose transmission chain.

[0004] The technical solution is as follows:

[0005] A vertical lifting mechanism with a ceiling rail comprises a supporting base and supporting columns symmetrically arranged at both ends of the top of the supporting base, a carrying mechanism is slidably arranged between the two supporting columns, the supporting base is provided with a driving mechanism for driving the carrying mechanism to move along the height direction of the supporting columns, the driving mechanism comprises a motor and two transmission chains with the same structure, the motor transmission is connected with a driving sprocket group, the driving sprocket group comprises two driving sprockets meshing with the transmission chains, one end of the two transmission chains is symmetrically arranged at the top of the carrying mechanism, and the other ends of the two transmission chains respectively bypass the driving sprocket group and multiple groups of driven sprocket groups and then extend into the carrying mechanism, wherein the characteristic is that two symmetrically arranged adjusting rods are respectively fixed on the two sides of the carrying mechanism corresponding to the two transmission chains, each of the adjusting rods is fixedly connected to the corresponding transmission chain, the other end of each adjusting rod extends upward to the outside of the carrying mechanism, a tensioning spring is sleeved on the section of each adjusting rod located outside the carrying mechanism, and a limiting member is fixedly arranged on the adjusting rod corresponding to the other end of each tensioning spring.

[0006] Through the above technical solution, by adjusting the setting of the spring, when the transmission chain drives the carrying mechanism to descend, the transmission chain will apply tension to the tension spring, which will cause the tension spring to be compressed first and then drive the carrying mechanism to move, thereby ensuring that the transmission chain is always in a tensioned state, avoiding the occurrence of an imbalance in the process of the carrying mechanism ascending due to the lengthening and loosening of the transmission chain after long-term and multiple uses, thereby effectively ensuring the stability of the carrying mechanism ascending process;

[0007] When the motor drives the transmission chain to drive the loading mechanism to rise, the elastic potential energy stored in the compressed tension spring will be released, which can keep the transmission chain in a tensioned state, thereby effectively ensuring the stability of the loading mechanism during its descent, thereby ensuring the accurate delivery of goods and improving cargo handling efficiency.

[0008] Preferably, the adjusting rod is a threaded rod, and the limiting member includes at least one nut threadably connected to the adjusting rod.

[0009] Preferably, a limit plate is provided at the bottom of the section of each adjusting rod located in the object-carrying mechanism, and a first connecting rod is connected between each of the limit plates arranged on the same side.

[0010] Preferably, the driven sprocket group includes six groups of driven sprocket groups with the same structure, each group of driven sprocket groups includes two driven sprockets meshing with the transmission chain; two groups of the six groups of driven sprocket groups are respectively arranged on two first connecting rods.

[0011] Preferably, a connecting beam is connected between the tops of the two support columns, and the connecting beam is arranged in a hollow shape in the middle; a second connecting rod and a third connecting rod are respectively arranged at both ends of the connecting beam, and a group of multiple driven sprocket groups are respectively arranged on the second connecting rod and the third connecting rod; a fourth connecting rod and a fifth connecting rod are respectively arranged at both ends of the support base corresponding to the lower side of the first connecting rod, and a group of six driven sprocket groups are respectively arranged on the fourth connecting rod and the fifth connecting rod.

[0012] Preferably, a sixth connecting rod is provided on one side of the support base close to the driving sprocket, and one of the six driven sprocket groups is provided on the sixth connecting rod.

[0013] Preferably, a protective cabinet is provided on the support base, the motor and the driving sprocket group are both arranged in the protective cabinet, a seventh connecting rod is provided in the protective cabinet, the seventh connecting rod is arranged above the driving sprocket group on one side close to the support column, and one of the six driven sprocket groups is provided on the seventh connecting rod.

[0014] To sum up, the beneficial effect of a vertical lifting mechanism with a ceiling rail is that by adjusting the setting of the spring, in the process of the transmission chain driving the carrying mechanism to descend, the transmission chain will apply tension to the tensioning spring, which will cause the tensioning spring to be compressed first and then drive the carrying mechanism to move, thereby ensuring that the transmission chain is always in a tensioned state, avoiding the occurrence of imbalance in the carrying mechanism during the ascent due to the lengthening and loosening of the transmission chain after long-term and multiple uses, thereby effectively ensuring the stability of the ascent process of the carrying mechanism; in the process of the motor driving the transmission chain to drive the carrying mechanism to rise, the elastic potential energy stored in the tensioning spring in a compressed state will be released, and this can make the transmission chain always in a tensioned state, thereby effectively ensuring the stability of the descending process of the carrying mechanism, thereby ensuring the accurate delivery of goods and improving the efficiency of cargo handling.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims.

[0023] In a possible embodiment, as shown in the attached Figure 1-4 As shown, a vertical lifting mechanism with a ceiling rail comprises a supporting base 1 and supporting columns 2 symmetrically arranged at both ends of the top of the supporting base 1, a carrying mechanism 3 is slidably arranged between the two supporting columns 2, a driving mechanism 4 for driving the carrying mechanism 3 to move along the height direction of the supporting columns 2 is arranged on the supporting base 1, the driving mechanism 4 comprises a motor 401 and two transmission chains 402 of the same structure, the motor 401 is connected to a driving sprocket group 5, the driving sprocket group 5 comprises two driving sprockets meshing with the transmission chains 402, one end of the two transmission chains 402 is symmetrically arranged at the top of the carrying mechanism 3, the other ends of the two transmission chains 402 respectively bypass the driving sprocket group 5 and multiple groups of driven sprocket groups and then extend into the carrying mechanism 3, and the two Two symmetrically arranged adjusting rods 6 are fixed on both sides of the carrying mechanism 3 corresponding to the transmission chain 402, and each adjusting rod 6 is fixedly connected to the corresponding transmission chain 402. The other end of each adjusting rod 6 extends upward to the outside of the carrying mechanism 3. The adjusting rod 6 is a threaded rod. A tensioning spring 7 is sleeved on the section of the adjusting rod 6 located outside the carrying mechanism 3. A limiting member 8 is fixedly arranged on the adjusting rod 6 corresponding to the other end of each tensioning spring 7. The limiting member 8 includes at least one nut threadedly connected to the adjusting rod 6; a limiting plate 9 is arranged at the bottom of the section of the adjusting rod 6 located in the carrying mechanism 3 in each adjusting rod 6, and a first connecting rod 10 is connected between each limiting plate 9 arranged on the same side.

[0024] In the process of the transmission chain 402 driving the carrying mechanism 3 to rise, the transmission chain 402 will apply a pulling force to the tensioning spring 7, which will cause the tensioning spring 7 to be compressed first and then drive the carrying mechanism 3 to move, thereby ensuring that the transmission chain 402 is always in a tensioned state, avoiding the occurrence of an imbalance in the rising process of the carrying mechanism 3 due to the lengthening and relaxation of the transmission chain 402 after long-term and multiple uses, thereby effectively ensuring the stability of the rising process of the carrying mechanism 3; in the process of the motor 401 driving the transmission chain 402 to drive the carrying mechanism 3 to descend, the tensioning spring 7 in a compressed state at this time stores elastic potential energy, which can make the transmission sprocket always in a tensioned state, thereby effectively ensuring the stability of the descending process of the carrying mechanism 3, thereby ensuring the accurate delivery of goods and improving the efficiency of cargo handling.

[0025] The driven sprocket group includes six groups of driven sprocket groups with the same structure, each group of driven sprocket groups includes two driven sprockets meshing with the transmission chain 402; two groups of the six groups of driven sprocket groups are respectively arranged on the two first connecting rods 10.

[0026] A connecting beam 11 is connected between the tops of the two support columns 2, and the connecting beam 11 is arranged in a hollow shape in the middle; a second connecting rod 12 and a third connecting rod 13 are respectively arranged at both ends of the connecting beam 11, and a group of multiple driven sprocket groups are respectively arranged on the second connecting rod 12 and the third connecting rod 13. In the present specific embodiment, the second connecting rod 12 is arranged at one end of the connecting beam 11 close to the motor 401; a fourth connecting rod 14 and a fifth connecting rod 15 are respectively arranged at both ends of the corresponding support base 1 below the first connecting rod 10, and a group of six driven sprocket groups are respectively arranged on the fourth connecting rod 14 and the fifth connecting rod 15; in the present specific embodiment, the fourth connecting rod 14 is arranged at one end of the support base 1 close to the motor 401.

[0027] A sixth connecting rod 16 is provided on one side of the support base 1 close to the driving sprocket, and one of the six driven sprocket groups is provided on the sixth connecting rod 16 ; in this specific embodiment, the sixth connecting rod 16 is provided on the left side of the fourth connecting rod 14 .

One of the six driven sprocket groups is arranged on the seventh connecting rod 18.

The specific connection structure and control method belong to the existing technology and will not be elaborated here.

[0029] Working principle: after the motor 401 is started, the output shaft of the motor 401 drives the two coaxially connected driving sprockets to rotate, and then the two transmission chains 402 are respectively transmitted along the driven sprockets. When the driving sprocket rotates clockwise, the carrying mechanism 3 moves downward, and each transmission chain 402 arranged in the carrying mechanism 3 will apply a pulling force to the adjusting rod 6, thereby compressing the tensioning spring 7 on the outer periphery of the adjusting rod 6 outside the carrying mechanism 3. After the tensioning spring 7 is compressed, with the continuous transmission of the transmission chain 402, the carrying mechanism 3 will be moved downward; when the carrying mechanism 3 needs to carry the goods upward, the motor 401 drives the driving sprocket to rotate in the opposite direction. At this time, the elastic potential energy stored in the transmission chain 402 due to compression will be released to ensure the balance of the reverse transmission of the transmission chain 402, thereby ensuring the stability of the transmission process of the transmission chain 402.
