Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of hydraulic equipment, and specifically relates to a multi-hydraulic-cylinder mechanical synchronous mechanism. BACKGROUND

[0002] Hydraulic oil cylinders are widely applied in the industrial field, and the synchronous extension and contraction operation of multiple hydraulic oil cylinders is one of the problems that need to be frequently faced. The more the number of hydraulic oil cylinders is, the more difficult it is to keep the synchronization between them. For the synchronization control of a large number of hydraulic cylinders, adjustment and cooperation between valve groups in a hydraulic system are generally utilized to realize, but with the increase of the number of hydraulic cylinders, the hydraulic system becomes more and more complex, thereby reducing the reliability of the system. SUMMARY

[0003] The utility model discloses a kind of multi-hydraulic-cylinder mechanical synchronous mechanism, and the synchronous operation of multiple oil cylinders is realized by mechanical structure, to reduce the complexity of hydraulic system, improve the reliability of hydraulic system.

[0004] To achieve its purpose, the present application adopts the following technical solutions:

[0005] A kind of multi-hydraulic-cylinder mechanical synchronous mechanism, including base piece and at least 2 sets of modularized synchronous components;

[0006] The base piece includes base and synchronous shaft;

[0007] The modularized synchronous component is installed on base, and the modularized synchronous component includes hydraulic cylinder, rack covering the full length of hydraulic cylinder is provided on the hydraulic cylinder, the bottom of rack is engaged with synchronous gear, and each synchronous gear is connected together through synchronous shaft.

[0008] As a further improvement of the utility model technical scheme, the bottom of hydraulic cylinder is fixedly connected on base, the top of hydraulic cylinder is connected with one end of rack, and the other end of rack is connected with the end head of hydraulic cylinder bottom telescopic rod through connecting block.

[0009] Further, the bottom of hydraulic cylinder is fixedly connected on base by bolt.

[0010] Further, the length of base and the length of synchronous shaft are expanded according to the number of hydraulic cylinders.

[0011] The utility model has the advantages of:

[0012] When several hydraulic cylinders are driven by a hydraulic system, the hydraulic rods of the hydraulic cylinders drive the racks to extend outward, and when the racks extend, the racks act on the synchronizing gears at the same time as the hydraulic rods of the hydraulic cylinders extend due to the mutual engagement between the racks and the synchronizing gears. The several synchronizing gears are connected in series on a synchronizing shaft. Therefore, the rotation of the several synchronizing gears is synchronized, so that the racks can also run synchronously, thereby ensuring that the hydraulic rods of the hydraulic cylinders perform synchronous extension and retraction actions.

[0013] The mechanism can ensure the synchronous extension and retraction of the plurality of hydraulic cylinders due to the fact that each set of rack and synchronizing gear is identical. Even if the performance of the hydraulic cylinders is slightly different, synchronous operation can be realized under the limitation of the mechanical structure. Meanwhile, the hydraulic system only needs to be simply configured, and does not need to be configured with too many valve parts in terms of synchronization, so that the hydraulic system can be effectively simplified and the reliability of the hydraulic system can be improved.

[0018] The specific composition and working process of the multi-hydraulic-cylinder mechanical synchronous mechanism of the utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] With reference to Figs. 1-3 The utility model provides a kind of multi-hydraulic-cylinder mechanical synchronous mechanism, including basic piece and 3 sets of modularized synchronous assembly 3;The basic piece includes base 1 and synchronizing shaft 2;The modularized synchronous assembly 3 is installed on base 1, and modularized synchronous assembly 3 includes hydraulic cylinder 3.1, rack 3.2 being equipped with covering the full length of hydraulic cylinder 3.1 on hydraulic cylinder 3.1, rack 3.2 bottom and synchronizing gear 3.4 are engaged, and each synchronizing gear 3.4 is connected together by synchronizing shaft 2.

[0020] Specifically, the bottom of the hydraulic cylinder 3.1 is fixed to the base 1 by bolts, the top of the hydraulic cylinder 3.1 is connected to one end of the rack 3.2, and the rod end of the bottom of the hydraulic cylinder 3.1 is connected to the other end of the rack 3.2 through the connecting block 3.3.

[0021] Specifically, the length of the base 1 and the length of the synchronous shaft 2 are expanded according to the number of the hydraulic cylinders 3.1.

[0022] The operation process of the mechanism is as follows:

[0023] When the hydraulic cylinders 3.1 are driven by the hydraulic system, the hydraulic rods of the hydraulic cylinders 3.1 drive the racks 3.2 to extend outward. When the racks 3.2 extend, the racks 3.2 act on the synchronous gears 3.4 due to the mutual engagement between the racks 3.2 and the synchronous gears 3.4 while the hydraulic rods of the hydraulic cylinders 3.1 extend. The synchronous gears 3.4 are connected in series on a synchronous shaft 2. Therefore, the rotation of the synchronous gears 3.4 is synchronized, so that the racks 3.2 can also operate synchronously, and further ensure that the hydraulic rods of the hydraulic cylinders 3.1 perform synchronous extension and retraction actions. Since each set of racks 3.2 and synchronous gears 3.4 is the same, the synchronous extension and retraction of the multiple hydraulic cylinders 3.1 can be ensured. Even if the performance of the hydraulic cylinders 3.1 is slightly different, the synchronous operation can be achieved under the limitation of the mechanical structure.
