It is made of refined raw materials, low water-cement ratio and optimized particle gradation through heat curing or steam curing process. Due to its excellent performance, UHPC prefabricated assembled beam device has been widely used in the construction industry. Concrete prefabricated assembled beam device refers to a device that uses concrete materials to prefabricate beam components and assembles them on site.

[0017] The present invention also discloses a method for using the above-mentioned UHPC prefabricated assembled beam splicing device, and the specific steps are as follows:

[0018] S1. Before splicing the UHPC prefabricated assembled beams, the position of the pushing mechanism is adjusted through the transmission member so that the pushing mechanism can drive the piston at the bottom to move, and then the piston at the bottom drives the hydraulic push rods on both sides to operate through the hydraulic oil, so that the hydraulic push rods can drive the fixing mechanisms on both sides to move through the support frame, so that the fixing mechanisms can fix beam components of different sizes;

[0019] S2. After the fixing mechanism has fixed the beam component, the placing frame and the beam component in its inner cavity are lifted to a corresponding height by a crane. At this time, if there is still a certain small distance between the beam component and the corresponding fixing component in the horizontal direction, the transmission member adjusts the position of the pushing mechanism again, so that the pushing mechanism can drive the piston located at the upper part to move, and then the piston located at the upper part drives the two hydraulic push rods to operate through the hydraulic oil;

[0020] S3. When the two hydraulic push rods are running, the two hydraulic push rods will drive the limit plate to move through the slide plate. At the same time, the slide plate will also drive the support frame to move, so that the limit plate and the support frame slide in the inner cavity of the limit mechanism, so that the beam member placed on the upper end of the support frame moves in the horizontal direction, so that the beam member can be aligned with the corresponding fixed component;

[0021] S4, when the beam component is aligned with the corresponding fixing part, at this time, the beam component is only aligned with the corresponding fixing part, but not in contact with the corresponding fixing part, and there is a certain distance between the two. At this time, the staff can use the hydraulic cylinder 2 to push the limit mechanism and the track wheel to move on the slide rail, so that the beam component is in contact with the corresponding fixing part, and then the staff can fix the beam component;

[0022] S5. After the beam component is fixed on the corresponding fixing part, the transmission part rotates the pushing mechanism again, so that the pushing mechanism drives the piston located at the bottom to move again, and the piston drives the fixing mechanisms on both sides to move through the hydraulic push rod 1 and the support frame, so that the fixing mechanisms on both sides release the fixing state of the beam component, and then the next beam component is assembled again in the above manner.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In the present invention, by providing a limiting device and a pushing device, during the process of assembling the UHPC prefabricated assembly beams, the staff cannot quickly and accurately lift the corresponding beam components to the corresponding assembly positions every time, and needs to make adjustments continuously. During this process, the limiting device and the pushing device can drive the beam components to be fine-tuned in the horizontal direction, so that the beam components are aligned with the corresponding fixed components, and there is no need to adjust them through a crane, thereby improving work efficiency.

[0025] 2. In the present invention, a transmission device is provided, which can be used to drive multiple hydraulic push rods 1 and two hydraulic push rods 2 in the limiting device to operate respectively, so that multiple hydraulic push rods 1 and two hydraulic push rods 2 respectively drive the support frame and the limiting plate to perform different operations, avoiding the need to set up multiple power sources to drive their operations separately, reducing energy consumption, and reducing the manufacturing cost of the device. At the same time, the positioning member can limit different components in the driving mechanism, thereby improving the stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] Embodiment 1

[0040] like Figure 1 — Figure 3 As shown, the present embodiment discloses a UHPC prefabricated assembly beam device which is easy to adjust, comprising a placement frame 1, four hook rings are arranged at the upper end of the placement frame 1, protective doors 2 are arranged on both sides of the outer surface of the placement frame 1, a limiting device 3 is arranged at the lower part of the inner cavity of the placement frame 1, a pushing device 6 is arranged at the lower end of the limiting device 3, and the pushing device 6 is fixedly installed on the bottom wall of the inner cavity of the placement frame 1, a plurality of fixing mechanisms 4 are arranged on both sides of the upper end of the limiting device 3, and a transmission device 5 is arranged on one side of the outer surface of the placement frame 1.

[0041] Furthermore, in order to fix the beam member, as Figure 2 and Figure 3 As shown, the fixing mechanism 4 includes a support rod 41 , a plurality of fixing plates 42 are arranged on the outer surface of the support rod 41 , and anti-skid particles are arranged in an array on the outer surface of the fixing plates 42 .

[0042] Specifically, before splicing the UHPC prefabricated assembly beams, the distance between the fixing mechanisms 4 on both sides of the upper end of the limiting device 3 can be adjusted according to the size of the beam component, and then the beam component is placed on the upper end of the limiting device 3, and then the fixing mechanisms 4 on both sides are used to fix the beam component. After that, the crane can be connected to the four lifting rings on the upper end of the placement frame 1, and the placement frame 1 and the beam component placed in the inner cavity of the placement frame 1 can be lifted through the lifting rings.

[0043] Furthermore, after the beam member is hoisted to the corresponding position, the transmission device 5 drives different components in the limiting device 3 to operate, so that the limiting device 3 drives the beam member to move, so that the beam member can be accurately spliced ​​at the corresponding position.

[0044] Furthermore, the protective door 2 is rotatably mounted on the outer surface of the placement frame 1 and can be opened and closed, and a locking mechanism is provided in the middle thereof. This is a prior art and will not be described in detail in this specification. At the same time, the locking mechanism is a prior art and the corresponding components are not drawn in the drawings of this specification and can be installed by oneself as needed.

[0045] In the process of splicing UHPC prefabricated assembled beams, different beam components need to be lifted to the corresponding positions by cranes for splicing. However, when the workers assemble the beam components on another beam component, the crane cannot accurately lift the beam components to the corresponding positions every time, and the workers need to constantly adjust the positions, which is time-consuming and labor-intensive. Figure 4 and Figure 5 As shown, the limiting device 3 includes a limiting plate 31, a slide plate 311 is provided in the middle of the lower end of the limiting plate 31, support frames 32 are provided on both sides of the outer surface of the limiting plate 31, and the upper ends of the two support frames 32 are respectively fixedly connected to the lower ends of the support rods 41 in the fixing mechanisms 4 on both sides, and the lower ends of the two support frames 32 are provided with multiple hydraulic push rods 34, and the extended ends of the hydraulic push rods 34 on both sides are fixedly connected to the outer surfaces of the slide plate 311 on both sides. A limiting mechanism 33 is provided below the two support frames 32, and the slide plate 311 and the multiple hydraulic push rods 34 are slidably installed in the inner cavity of the limiting mechanism 33. Two hydraulic push rods 35 are provided on the side of the outer surface of the limiting mechanism 33 close to the transmission device 5, and the extended ends of the two hydraulic push rods 35 are also fixedly connected to the outer surface of the slide plate 311.

[0046] Specifically, before placing the beam component in the inner cavity of the placement frame 1, the positions of the two support frames 32 can be adjusted by the hydraulic push rods 34 on both sides, so that the two support frames 32 drive the fixing mechanisms 4 on both sides to move, so that the device can place beam components of different sizes.

[0047] Furthermore, after the beam component is placed on the upper ends of the two support frames 32, the two support frames 32 are driven to move toward each other through the hydraulic push rods 34 on both sides, so that the hydraulic push rods 34 on both sides clamp the beam component as the support frames 32 move. During this process, the staff can also fix the beam component again through the corresponding ropes.

[0048] Furthermore, after the beam component is fixed, the crane can lift the beam component to a corresponding height through the placement frame 1. At this time, if the beam component has not been completely aligned with the corresponding fixing component, the position of the limit plate 31 can be adjusted by the hydraulic push rod 2 35. Since the protruding ends of the hydraulic push rod 2 35 and the hydraulic push rod 1 34 are both connected to the surface of the slide plate 311, when the limit plate 31 moves, the support frame 32 will also be driven to slide in the inner cavity of the limit mechanism 33 through the slide plate 311 and the hydraulic push rod 1 34, so as to adjust the horizontal position of the beam component placed on the upper end of the support frame 32.

[0049] In order to fine-tune the beam member placed on the upper end of the support frame 32 in the horizontal direction, as shown in FIG. Figure 5 As shown, the limiting mechanism 33 includes a limiting frame 331, the outer surface of the inner cavity of the limiting frame 331 is slidably connected to the outer surface of the slide plate 311, a plurality of slide grooves 332 are opened on the bottom wall of the inner cavity of the limiting frame 331, a plurality of hydraulic push rods 34 are slidably installed in the middle of the inner cavity of the slide groove 332, and a plurality of slideways 333 are arranged on both sides of the outer surface of the limiting frame 331, the inner cavity of the slideway 333 is communicated with the inner cavity of the limiting frame 331, the plurality of slideways 333 located on both sides correspond to the plurality of slide grooves 332, and the inner cavity bottom wall of the slideway 333 is flush with the inner cavity bottom wall of the slide groove 332.

[0050] Further, such as Figure 6 As shown, the pushing device 6 includes three slide rails 61 and two hydraulic cylinders 63, and the three slide rails 61 and the two hydraulic cylinders 63 are all fixedly installed on the bottom wall of the inner cavity of the placing frame 1. The three slide rails 61 and the two hydraulic cylinders 63 are distributed at intervals, and the upper ends of the three slide rails 61 are each provided with a plurality of track wheels 62, and the upper ends of the plurality of track wheels 62 are each fixedly connected to the lower end of the limiting mechanism 33.

[0051] Specifically, when it is necessary to adjust the distance between the fixing mechanisms 4 on both sides, the hydraulic push rods 34 on both sides extend or retract. At this time, the two hydraulic push rods 35 will not drive the slide plate 311 to operate, so that the hydraulic push rods 34 on both sides drive themselves to move during the extension or retraction process, and then the hydraulic push rods 34 on both sides respectively drive the two support frames 32 to operate, so as to achieve the purpose of adjusting the distance between the fixing mechanisms 4 on both sides.

[0052] Furthermore, after the positions of the two support frames 32 are adjusted, when the horizontal position of the beam component needs to be adjusted, the two hydraulic push rods 35 will push the limit plate 31 to operate through the slide plate 311. Since the hydraulic push rod 1 34 will not operate at this time, when the hydraulic push rod 2 35 pushes the limit plate 31 to operate through the slide plate 311, the two support frames 32 will also be driven to move together through the hydraulic push rod 1 34, thereby adjusting the position of the beam component.

[0053] Furthermore, after the position of the beam component is adjusted by the hydraulic push rod 2 35, at this time, the beam component is only aligned with the corresponding fixed component, and is not in contact with the corresponding fixed component. There is a certain distance between the two. Since the upper end of the track wheel 62 is fixedly connected to the lower end of the limiting mechanism 33, the staff can push the limiting mechanism 33 to operate through the hydraulic cylinder 2 63. Since the limiting plate 31 and the support frame 32 are both slidably installed in the inner cavity of the limiting mechanism 33 through corresponding components, when the limiting mechanism 33 is running, it will drive the beam component to run through the support frame 32 and run to the side close to the fixed component.

[0054] Furthermore, in order to prevent the placement frame 1 from tipping over and causing the beam member to fall due to a large deviation of the center of gravity, the hydraulic cylinder 2 63 pushes the limiting mechanism 33 to move a small distance, and can only be adjusted within a certain distance.

[0055] Embodiment 2

[0056] This embodiment further improves the transmission device 5 on the basis of the first embodiment, so that the transmission device 5 can drive the hydraulic push rod 1 34 and the hydraulic push rod 2 35 in the limit device 3 to operate respectively. Figure 7 As shown, the transmission device 5 includes a hydraulic mechanism 51 and a hydraulic cylinder 55, and the hydraulic mechanism 51 and the hydraulic cylinder 55 are both fixedly mounted on the outer surface of the placement frame 1. A pushing mechanism 52 is arranged on the upper part of the inner cavity of the hydraulic mechanism 51, and the upper end of the pushing mechanism 52 extends to the outside of the hydraulic mechanism 51, and the upper end of the pushing mechanism 52 is fixedly connected to the output end of the hydraulic cylinder 55. A positioning member 53 is arranged on the upper end of the hydraulic mechanism 51, and the positioning member 53 is adapted for use with the pushing mechanism 52. A transmission member 54 is arranged on the upper part of the outer surface of the pushing mechanism 52, and the transmission member 54 is fixedly mounted on the output end of the hydraulic cylinder 55.

[0057] Specifically, when the distance between the two support frames 32 needs to be adjusted, the transmission member 54 drives the pushing mechanism 52 to rotate and adjusts the pushing mechanism 52 to a corresponding state. At this time, the output of the hydraulic cylinder 55 drives the pushing mechanism 52 to move downward, so that the pushing mechanism 52 drives the hydraulic oil at the corresponding position in the inner cavity of the hydraulic mechanism 51 to enter the inner cavity of the hydraulic push rods 34 on both sides, thereby making the hydraulic push rods 34 on both sides drive the two support frames 32 to operate.

[0058] Furthermore, when it is necessary to adjust the horizontal position of the beam component, the transmission member 54 adjusts the pushing mechanism 52 to a corresponding state again, and then the hydraulic cylinder 1 55 drives the pushing mechanism 52 to move, so that the pushing mechanism 52 drives the corresponding components in the inner cavity of the hydraulic mechanism 51 to act on the two hydraulic push rods 2 35, and then the two hydraulic push rods 2 35 drive the limit plate 31 and the support frame 32 to operate.

[0059] Furthermore, when the hydraulic cylinder 55 drives the pushing mechanism 52 to operate, it will also drive the positioning member 53 to operate, so that the positioning member 53 can restrict the corresponding parts in 52 that do not need to move.

[0060] Furthermore, the transmission member 54 is composed of a small motor and two meshing gears, and the small motor is fixedly mounted on the outer surface of the output shaft of the hydraulic cylinder 55. This is the prior art and will not be described in detail in this specification.

[0061] In order to respectively drive the hydraulic push rod 1 34 and the hydraulic push rod 2 35 to operate, as shown in FIG. Figure 8 and Fig. 9 As shown, the hydraulic mechanism 51 includes a hydraulic mechanism 51, a partition 512 is provided in the middle of the inner cavity of the hydraulic mechanism 51, pistons 513 are provided on the upper and lower sides of the inner cavity of the hydraulic cylinder 511, the space between the upper end of the piston 513 located at the upper part and the top wall of the inner cavity of the hydraulic cylinder 511 is filled with hydraulic oil, the space between the upper piston 513 and the hydraulic cylinder 511 is communicated with the inner cavity of the two hydraulic push rods 2 35 through a hydraulic pipe, the space between the lower end of the piston 513 located at the lower part and the bottom wall of the inner cavity of the hydraulic cylinder 511 is also filled with hydraulic oil, and the space between the lower piston 513 and the hydraulic cylinder 511 is communicated with the inner cavity of multiple hydraulic push rods 1 34 located on both sides through two hydraulic pipes.

[0062] Specifically, when the transmission member 54 adjusts the pushing mechanism 52 to the corresponding device, at this time, the hydraulic cylinder 1 55 drives the piston 513 at the bottom to move through the pushing mechanism 52, so that the hydraulic pressure at the bottom of the piston 513 enters the inner cavity of the hydraulic push rod 1 34, and then the hydraulic push rod 1 34 drives the support frame 32 to operate. When the transmission member 54 adjusts the pushing mechanism 52 to another state again, at this time, the hydraulic cylinder 1 55 drives the piston 513 at the top to operate through the pushing mechanism 52, so that the hydraulic mechanism 51 injects the hydraulic oil in the upper part of its inner cavity into the inner cavity of the two hydraulic push rods 2 35 or absorbs the hydraulic oil in the inner cavity of the two hydraulic push rods 2 35 into its inner cavity, so that the hydraulic push rod 2 35 can drive the limit plate 31 and the support frame 32 to slide in the inner cavity of the limit mechanism 33.

[0063] In order to drive the limiting device 3 to move in different ways to achieve different adjustment purposes, such as Figure 8As shown, the pushing mechanism 52 includes a pushing rod 521, and three rows of transmission blocks 5211 are arranged on the outer surface of the pushing rod 521. A connecting block 524 is fixedly connected to the upper portion of the outer surface of the pushing rod 521, and the upper portion of the connecting block 524 is rotatably connected to the output end of the hydraulic cylinder 55. The outer surface of the connecting block 524 is fixedly connected to the inner wall of the spur gear located near one side of the transmission member 54. An inner connecting member 522 is arranged on the lower portion of the outer surface of the pushing rod 521, and the inner connecting member 522 extends to the lower portion of the inner cavity of the hydraulic cylinder 511, and the lower end of the inner connecting member 522 is fixedly connected to the upper end of the piston 513 located at the lower portion, and an outer connecting member 523 is arranged on the middle portion of the outer surface of the inner connecting member 522, and the lower end of the outer connecting member 523 is fixedly connected to the upper end of the piston 513 located at the upper portion.

[0064] In order to drive the pistons 513 on the upper and lower sides to move respectively by a power source, such as Fig.10 As shown, the internal connecting member 522 includes a connecting cylinder 5221, the lower end of which is fixedly connected to the upper end of the piston 513 located at the lower part, the outer surface of the connecting cylinder 5221 is evenly provided with three limiting grooves 5222, the inner cavity array of the connecting cylinder 5221 is provided with three rows of driven blocks 5223, the three rows of driven blocks 5223 are spaced apart from the three limiting grooves 5222, and the upper portion of the outer surface of the connecting cylinder 5221 is provided with three limiting blocks 5224, the three limiting blocks 5224 correspond one-to-one to the three rows of driven blocks 5223.

[0065] Further, such as Fig. 9 As shown, the external connecting member 523 includes a connecting cylinder 2 5231, the lower end of which extends to the inner cavity of the hydraulic cylinder 511 and is fixedly connected to the upper end of the piston 513 located at the upper part, and the connecting cylinder 2 5231 is sleeved on the outer surface of the internal connecting member 522, and the inner cavity surface of the connecting cylinder 2 5231 is provided with three rows of follower blocks 2 5233, and the three rows of follower blocks 2 5233 respectively pass through the three limiting grooves 5222 and extend to the interior of the connecting cylinder 1 5221, and three limiting blocks 2 5232 are provided on the upper part of the outer surface of the connecting cylinder 2 5231, and the three limiting blocks 2 5232 correspond one-to-one to the three rows of follower blocks 2 5233.

[0066] Specifically, when it is necessary to adjust the positions of the two support frames 32 through the hydraulic push rod 34, the transmission member 54 drives the push rod 521 to rotate through the connecting block 524, so that the three rows of transmission blocks 5211 on the outer surface of the push rod 521 enter the gaps between the three rows of driven blocks 5223 in the inner cavity of the inner connecting member 522, so that the transmission blocks 5211 and the driven blocks 5223 are stacked together, just like gear meshing. At this time, the hydraulic cylinder 55 drives the push rod 521 to move downward or upward through the connecting block 524, so that the push rod 521 drives the piston 513 located at the bottom to make corresponding movements through the inner connecting member 522.

[0067] Furthermore, when it is necessary to drive the limit plate 31 and the support frame 32 to slide in the inner cavity of the limit mechanism 33 through the hydraulic push rod 2 35, the transmission member 54 drives the push rod 521 to rotate again, so that the three rows of transmission blocks 5211 on the outer surface of the push rod 521 enter the gaps of the three rows of follower blocks 2 5233 in the inner cavity of the external connecting member 523, and then the hydraulic cylinder 1 55 drives the piston 513 located at the upper part to operate through the push rod 521, so that the hydraulic push rod 2 35 drives the limit plate 31 and the support frame 32 to slide in the inner cavity of the limit mechanism 33.

[0068] Furthermore, when the three rows of transmission blocks 5211, driven block 1 5223 and driven block 2 5233 on the outer surfaces of the push rod 521, the inner connecting member 522 and the outer connecting member 523 are not stacked together, they just form a circular ring when viewed from top to bottom. When it is necessary to adjust the height of the push rod 521 and do not want to drive the inner connecting member 522 and the push rod 521 to move, the push rod 521 can be adjusted to a position where it does not contact the inner connecting member 522 and the outer connecting member 523 through the transmission member 54. At this time, the position of the push rod 521 can be adjusted.

[0069] In order to limit the inner connecting member 522 and the outer connecting member 523, as shown in FIG. Fig.11 As shown, the positioning member 53 includes a positioning cylinder 531, which is adapted for use with a connecting cylinder 5231. The positioning cylinder 531 is rotatably mounted on the upper end of the hydraulic cylinder 511. The inner surface of the positioning cylinder 531 is provided with three rows of positioning blocks 532. The three rows of positioning blocks 532 are adapted for use with three limit blocks 5232. The upper end of the positioning cylinder 531 is provided with a positioning cylinder 533. The upper end of the positioning cylinder 533 is fixedly connected to the lower part of the outer surface of the connecting block 524. The positioning cylinder 533 is adapted for use with the connecting cylinder 5221. The inner surface of the positioning cylinder 533 is provided with three rows of positioning blocks 534. The three rows of positioning blocks 534 are adapted for use with the three limit blocks 5224.

[0070] Specifically, when the push rod 521 drives the piston 513 at the bottom to operate through the inner connecting member 522, the transmission member 54 drives the push rod 521 to rotate through the connecting block 524, and also drives the positioning member 53 to operate. When the transmission member 54 connects the push rod 521 with the inner connecting member 522, the limit block 2 5232 also enters the gap between the two positioning blocks 1 532 in a row of positioning blocks 1 532 corresponding to the inner cavity of the positioning cylinder 1 531, so that the positioning member 53 restricts the external connecting member 523. Conversely, when the push rod 521 drives the external connecting member 523 to operate, the connecting block 524 on the upper part of the internal connecting member 522 also enters the gap between the two positioning blocks 2 534 in a row of positioning blocks 2 534 corresponding to the inner cavity of the positioning cylinder 2 533, so as to restrict the internal connecting member 522.

[0071] Furthermore, when the push rod 521 moves up and down without driving the inner connecting member 522 and the outer connecting member 523 , the positioning member 53 will restrict the inner connecting member 522 and the outer connecting member 523 at the same time.

[0072] Embodiment 3

[0073] The present application also discloses a method for using a UHPC prefabricated assembly beam device that is easy to adjust, and the specific steps are as follows:

[0074] S1. Before splicing the UHPC prefabricated assembled beams, the position of the pushing mechanism 52 is adjusted through the transmission member 54, so that the pushing mechanism 52 can drive the piston 513 at the bottom to move, and then the piston 513 at the bottom drives the hydraulic push rods 34 on both sides to operate through the hydraulic oil, so that the hydraulic push rods 34 can drive the fixing mechanisms 4 on both sides to move through the support frame 32, so that the fixing mechanisms 4 can fix beam components of different sizes;

[0075] S2. After the fixing mechanism 4 has fixed the beam component, the placing frame 1 and the beam component in the inner cavity of the placing frame 1 are lifted to a corresponding height by a crane. At this time, if there is still a certain small distance between the beam component and the corresponding fixing component in the horizontal direction, the transmission member 54 adjusts the position of the pushing mechanism 52 again, so that the pushing mechanism 52 can drive the piston 513 at the upper part to move, and then the piston 513 at the upper part drives the two hydraulic push rods 35 to operate through the hydraulic oil;

[0076] S3. When the two hydraulic push rods 35 are in operation, the two hydraulic push rods 35 will drive the limit plate 31 to move through the slide plate 311. At the same time, the slide plate 311 will also drive the support frame 32 to move, so that the limit plate 31 and the support frame 32 slide in the inner cavity of the limit mechanism 33, so that the beam member placed on the upper end of the support frame 32 moves in the horizontal direction, so that the beam member can be aligned with the corresponding fixing component;

[0077] S4, when the beam component is aligned with the corresponding fixing part, at this time, the beam component is only aligned with the corresponding fixing part, but not in contact with the corresponding fixing part, and there is a certain distance between the two. At this time, the staff can use the hydraulic cylinder 2 63 to push the limit mechanism 33 and the track wheel 62 to move on the slide rail 61, so that the beam component is in contact with the corresponding fixing part, and then the staff can fix the beam component;

[0078] S5. After the beam component is fixed on the corresponding fixing part, the transmission member 54 rotates the pushing mechanism 52 again, so that the pushing mechanism 52 can drive the piston 513 located at the bottom to move again, so that the piston 513 drives the fixing mechanisms 4 on both sides to move through the hydraulic push rod 34 and the support frame 32, so that the fixing mechanisms 4 on both sides release the fixing state of the beam component, and then the next beam component is assembled again in the above manner.

[0079] It should be noted that the specific installation method, circuit arrangement connection method and control method of the hydraulic cylinder 2 63 used in the above-mentioned embodiment 1 and the transmission member 54 and the hydraulic cylinder 1 55 used in the embodiment 2 are all conventional designs in the prior art and will not be elaborated in detail in the present invention.
