[0026] As shown in Figure 1 , 2 The present embodiment provides a hydraulic lifting platform system, which comprises a bottom plate 1 and a face plate 2, and a plurality of hydraulic lifting assemblies are arranged between the bottom plate 1 and the face plate 2 in an extendable and retractable manner, wherein each hydraulic lifting assembly comprises:

[0027] A first driver 3, comprising a first body 4 and a first telescopic column 5, and a mounting groove 6 is recessed on the plate surface of the bottom plate 1, the first body 4 is detachably arranged in the mounting groove 6 and the first telescopic column 5 extends upward;

[0028] A second driver 7, comprising a second body 8 and a second telescopic column 9, the second body 8 abuts against the end of the first telescopic column 5, and the end of the second telescopic column 9 abuts against the face plate 2;

[0029] The upper end of the mounting groove 6 is further provided with a support table 10 for abutting against the second body 8, in particular, the support table 10 in the present embodiment is recessed on the bottom plate 1, and all the mounting grooves 6 are located within the range covered by the support table 10.

[0030] In the above embodiment, the panel 2 and the bottom plate 1 are supported by a plurality of hydraulic lifting assemblies, which are similar to those in the prior art, so as to ensure that the panel 2 is stably supported. Different from the prior art, the hydraulic lifting assembly in the embodiment comprises a first driver 3 and a second driver 7 arranged in a vertical manner. The first body 4 of the first driver 3 is located in the mounting groove 6, the first telescopic column 5 supports the second body 8, and the second telescopic column 9 supports the panel 2, so that the panel 2 is stably supported. When maintenance is needed, part of the second driver 7 is started to move the part of the second telescopic column 9 downward to be separated from the panel 2. At this time, another part of the second telescopic column 9 still supports the panel 2, avoiding the panel 2 from falling accidentally. Then, the second driver 7 after falling is maintained, and the second driver 7 can be removed from the first telescopic column 5, so as to facilitate the maintenance of the first driver 3. After the reassembly, the other part of the second driver 7 and the first driver 3 are maintained. During the whole process, the maintenance is alternately performed, which minimizes the adverse effects on the panel 2, so that the panel 2 is still supported during the maintenance process, thereby reducing the risk of accidental falling of the panel 2.

[0031] Although the prior art can temporarily start part of the driver, the driver in the prior art cannot be removed from between the bottom plate 1 and the panel 2, and the whole maintenance process still needs to be completed below the panel 2. In the embodiment, the second driver 7 can be removed and can be maintained externally, so as to reduce the risk. Meanwhile, the first driver 3 can also be removed, which further reduces the risk of maintenance.

[0032] In particular, as shown in Figure 1 , when the panel 2 is supported, the first driver 3 can be in an inoperative state, i.e., the first telescopic column 5 is located in the mounting groove 6 and does not support the second hydraulic drive. The support table 10 supports the second driver 7. When maintenance is needed, part of the first driver 3 supports the second driver 7, and the second telescopic column 9 of all the second drivers 7 is retracted. Then, part of the second telescopic column 9 is separated from the panel 2, and part of the second telescopic column 9 is always in contact with the panel 2, so as to ensure that the panel 2 is normally supported (i.e., the second driver 7 connected with the first driver 3 in operation continuously supports, and the other second driver 7 is separated from the support for maintenance). During the maintenance, the other part of the first driver 3 that does not participate in the support is started to lift the second driver 7 connected with the first telescopic column 5. Then, the first driver 3 and the second driver 7 separated from the support are removed for maintenance.

[0033] Preferably, as shown in Figure 1 , 2As shown, the second body 8 is fixedly connected with a mounting plate 11 at one end away from the second telescopic column 9, the mounting plate 11 is recessed with a clamping groove on the side away from the second body 8, the first telescopic column 5 is clamped with the clamping groove (similarly, a clamping groove for clamping the second telescopic column 9 can also be provided on the panel 2 to improve the connection stability between the panel 2 and the second telescopic column 9, and also to play a positioning role, so that the second telescopic column 9 can be aligned with the fixed position during installation, thereby avoiding changes in the support position after maintenance, ensuring that the support position is stable and unchanged each time, and ensuring the safety of system operation), the mounting plate 11 abuts against the support table 10, and the mounting plate 11 provides a support basis between the second body 8 and the bottom plate 1, thereby ensuring that the first driver 3 is normally accommodated in the mounting groove 6 and can not bear the pressure transmitted by the second driver 7.

[0034] Preferably, as shown in Figure 1 , 2 , the first telescopic column 5 is provided with a telescopic cylinder 12, the upper end of the telescopic cylinder 12 is detachably connected with the mounting plate 11, and the lower end abuts against the upper end surface of the first body 4, the telescopic cylinder 12 provided here is used for protecting the first telescopic column 5, when the panel 2 is supported, the first telescopic column 5 is at a lower position, and in some use environments, there may be a risk of pollution by particulate matter at the lower position, so the telescopic cylinder 12 is needed to protect the first telescopic column 5, for example, in a cement or coal mine production workshop, dust will accumulate at the lower position and thus adhere to the first telescopic column 5, which will cause wear of the outer wall of the first telescopic column 5 when the first telescopic column 5 is telescoped, therefore, the telescopic cylinder 12 is provided outside the first telescopic column 5 for protection, specifically, the lower end of the telescopic cylinder 12 is fixedly connected with a bottom ring 13 surrounding the outside thereof, the outer ring wall of the bottom ring 13 is fixedly connected with a flexible cylinder 14, the flexible cylinder 14 is vertically arranged and the upper end thereof is fixedly connected with a first support ring 15, and the first support ring 15 is clamped with the support table 10, so that a ring-shaped barrel is provided outside the first telescopic column 5, dust and impurities will accumulate in the barrel, and the barrel can be directly taken out for cleaning in the subsequent cleaning process, the upper end of the telescopic cylinder 12 abuts against the mounting plate 11 through a connecting ring 16, that is, the upper end of the telescopic cylinder 12 is detachable, so that it can be disconnected from the mounting plate 11 without affecting the disassembly of the first driver 3, and after the first driver 3 is disassembled, the telescopic cylinder 12 and the flexible cylinder 14 can be taken out upward to clean the accumulated impurities.

[0035] Preferably, as shown in Figure 1 , 2As shown, in order to facilitate the installation of the flexible cylinder 14, the support table 10 is also recessed with an annular table around the upper end of each installation slot 6 for the clamping of the first support ring 15, the first support ring 15 is clamped on the support table 10, and the upper end surface of the first support ring 15 is flush with the bottom surface of the support table 10, so as not to affect the abutment of the mounting plate 11.

[0036] Preferably, as shown in Figure 1 , 2 , the telescopic cylinder 12 includes a plurality of telescopic sections 17 connected with each other, all the telescopic sections 17 are realized to be contracted and expanded in a stack structure, the telescopic section 17 located at the uppermost end is fixedly connected with the connecting ring 16, the connecting ring 16 is connected with the mounting plate 11 through the first bolt 18, and the telescopic section 17 located at the lowermost end is fixedly connected with the bottom ring 13, so that the telescopic cylinder 12 thus arranged can be telescoped with the first telescopic column 5, and at the same time, the telescopic section 17 is made of a plastic cloth material with folding resistance, thereby having a higher service life, and in particular, the flexible cylinder 14 thus arranged can also be made of a plastic cloth material and can also be folded.

[0037] Preferably, as shown in Figure 1 , 2 , the panel 2 is fixedly connected with the surrounding plate 19 surrounding all the second telescopic columns 9, and the surrounding plate 19 is further fixedly connected with the reinforcing plate 20, all the second telescopic columns 9 abut against the panel 2 and slide with the reinforcing plate 20 (i.e., the reinforcing plate 20 is provided with holes for the sliding of the second telescopic columns 9), the surrounding plate 19 is arranged to surround the outside, and all the second telescopic columns 9 are located inside the surrounding plate 19, and the reinforcing plate 20 provides a second connecting point for the second telescopic columns 9, so that the support of the second telescopic columns 9 to the panel 2 remains vertical, and the first support point is the abutment point between the second telescopic columns 9 and the panel 2; further, the lower end surface of the surrounding plate 19 is further fixedly connected with at least one pair of guide rods 21, and the bottom plate 1 is further recessed with at least one pair of guide holes 22 for the sliding cooperation of each guide rod 21, the lower end of the guide rod 21 is in sliding cooperation with the corresponding guide hole 22 and always in contact with each other (i.e., not separated), and the panel 2 and the bottom plate 1 are indirectly connected through the plurality of guide rods 21, so that the guide rod 21 slides up and down relative to the abutment plate (i.e., the guide hole 22) while the panel 2 is lifted and lowered, and the guide rod 21 will not deviate under the guidance of the guide hole 22, so that the lifting and lowering of the panel 2 will not deviate, thereby ensuring the stable lifting and lowering of the panel 2; in particular, the guide rod 21 and the guide hole 22 are arranged in the embodiment because the second telescopic column 9 and the panel 2 are in abutment rather than fixed connection in the prior art, so that the guide rod 21 is arranged to guide the second telescopic column 9 and the panel 2 to prevent the deviation of the second telescopic column 9 and the panel 2 from each other during the lifting and lowering process;

[0038] Further, the guide rod 21 is hollow and its lower end communicates with the guide hole 22 and its upper end communicates with the outside through the through hole 23 arranged on its wall. The guide hole 22 has a large depth, thus ensuring that the guide rod 21 will not be separated from the guide hole 22, and at the same time, the sliding contact between the two enables a certain sealing degree in the guide hole 22. The hollow structure and the through hole 23 enable the guide hole 22 to communicate with the outside smoothly, thus enabling the guide hole 22 to be in a pressure balance state with the outside, avoiding the consumption of mechanical energy for overcoming the work caused by sealing when the panel 2 is lifted or lowered, and being beneficial to reducing the energy consumption.

[0039] Preferably, as shown in Figure 1 、 2 In order to make the hydraulic lifting assembly of the embodiment run more smoothly, the supporting table 10 is further abutted with a second supporting ring 24 surrounding the mounting groove 6, the mounting plate 11 is detachably mounted with a third supporting ring 25, and the second supporting ring 24 and the third supporting ring 25 are fixedly connected with a supporting spring 26 surrounding the first telescopic column 5 (at the same time, the supporting spring 26 also surrounds the mounting plate 11). The second supporting ring 24 and the third supporting ring 25 provide a mounting basis for the supporting spring 26, and the supporting spring 26 surrounds the first telescopic column 5 and can provide auxiliary support for the first driver 3, thus making the operation of the overall hydraulic lifting assembly more stable. In particular, the third supporting ring 25 in the embodiment is connected with the upper plate surface of the mounting plate 11 through the second bolt 27 and surrounds the second body 8, so that when the mounting plate 11 is lowered and abuts against the supporting table 10, the supporting spring 26 can be compressed between the second supporting ring 24 and the third supporting ring 25, and the thickness of the mounting plate 11 is larger, providing a reserved space for the compression of the supporting spring 26, avoiding the over-compression of the supporting spring 26. Further, a containing ring groove surrounding the first supporting ring 15 can be recessed on the supporting table 10 to contain the second supporting ring 24, so that the reserved space is higher, and the compression degree of the supporting spring 26 is further reduced.
