Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, specifically, it relates to a walking automatic lifting device for building construction machines. Background Technology

[0002] A building construction machine is a specialized piece of equipment used in the construction of high-rise buildings. Its main function is to construct the building structure layer by layer using mechanized means. The machine utilizes a guide rail system installed on the exterior of the building, employing robotic arms and lifting devices to transport building materials to designated locations floor by floor, achieving rapid and efficient construction. The application of building construction machines not only improves construction efficiency but also reduces labor costs and construction safety hazards.

[0003] Automatic jacking devices are an important component of building construction machines. Their main function is to achieve vertical movement of the entire machine through hydraulic or mechanical systems, allowing it to be smoothly lifted to the next floor after completion. Currently, most automatic jacking devices on the market rely on hydraulic or mechanical gear systems. Through the coordinated operation of these systems, the building construction machine can be lifted smoothly.

[0004] However, existing automatic jacking devices have some drawbacks or defects in use. First, in terms of safety, due to the complexity and high-pressure characteristics of the hydraulic system, leaks or malfunctions may lead to sudden loss of control during the jacking process, causing personal injury or equipment damage. Furthermore, the mechanical gear system may experience wear and jamming after long-term use, affecting the smoothness and safety of the jacking process. Second, in terms of stability, existing jacking devices are prone to tilting and swaying under uneven loads or when the jacking height is large, affecting construction accuracy and efficiency.

[0005] In conclusion, existing automatic jacking devices still have significant room for improvement in terms of safety, stability, and ease of operation. To address these issues, designing a safer, more stable, and easier-to-operate walking-type automatic jacking device for building construction machines is of paramount importance.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A building construction machine walking automatic jacking device includes a vertical guide rail, on the surface of which two bases are slidably disposed, and the opposing surfaces of the two bases are fixedly connected to a tension spring, and the opposing surfaces of the two bases are slidably connected to two hydraulic shear seats.

[0009] Two hydraulic shear seats are fixed together on their surfaces with two coordinating frames. The top and bottom safety seats are movably connected to the two ends of the two coordinating frames, respectively.

[0010] The inner walls of the top safety seat, bottom safety seat, and both bases are all equipped with tensioners for fall prevention.

[0011] A platform seat is fixedly connected to the upper surface of the base, and two load-bearing sliding columns are fixedly connected to one side of the platform seat. The bottom end of the load-bearing sliding column is fixedly connected to the upper surface of the base.

[0012] Preferably, the base includes a limiting slide that slides on the surface of a vertical guide rail. A seat body is fixedly connected to the surface of the limiting slide. A limiting slide groove that slides in cooperation with a hydraulic shear seat is provided on the upper surface of the seat body. A tie rod is fixedly connected to one side of the seat body and is fixedly connected to one end of a tension spring.

[0013] Preferably, the surface of the top safety seat is fixed with two load-bearing slide bars, and the load-bearing slide column is slidably disposed on the surface of the load-bearing slide bars.

[0014] Preferably, the hydraulic shear seat includes a hydraulic seat fixed to one side of the seat body, a hydraulic rod is fixedly fixed through one side of the hydraulic seat, a push block is fixedly connected to the telescopic end of the hydraulic rod, a limit slide is fixedly connected to the upper surface of the push block, and the limit slide is slidably disposed on the inner wall of the limit slide groove.

[0015] Preferably, the vertical guide rail includes two interlocking and pressing diagonal braces. The two diagonal braces have guide grooves on their opposite sides for sliding with the top safety seat, the bottom safety seat, and the two limiting slides. One side of the two diagonal braces has a communicating safety groove. The tensioner is slidably disposed on the inner wall of the safety groove.

[0016] Preferably, one side of the push block is inclined, and the inclined surfaces of the push blocks of the two hydraulic shear seats are in a sliding contact state.

[0017] Preferably, the tensioner includes several movable pins, and two pressure members are movably connected to the surface of each movable pin. One end of each pressure member is movably connected to a pressure block via a pin shaft, and several springs are fixedly connected to the opposite surfaces of the two pressure blocks.

[0018] Preferably, the coordinating frame includes a mounting frame fixedly connected to one side of the push block, a first support plate being movably connected to the surface of the mounting frame via a pin, a support slide rail being fixedly connected to one side of the mounting frame, a sliding pin seat being slidably limited on the inner wall of the support slide rail, and a second support plate being movably connected to the surface of the sliding pin seat;

[0019] The first and second support plates of the two cooperating frames are movably connected to both sides of the top and bottom safety seats.

[0020] Preferably, the mating surfaces of the safety groove and the pressure block include, but are not limited to, flat surfaces, frosted surfaces, wavy surfaces, or oblique toothed surfaces that fit together.

[0021] Beneficial effects:

[0022] This design utilizes the cooperation of two hydraulic shear seats, causing the two push blocks to press against each other under hydraulic pressure, providing continuous vertical support. The misalignment of the two push blocks alters their relative support height, causing the lower base to experience a downward force. This downward force is controlled by an internal tensioner, while the upper base begins to move upwards. At this point, the tensioner slides against the inner wall of the safety groove. As the two push blocks move away from each other, the upper base loses its support force and, with the help of the tensioner, begins to provide support. The two push blocks then move away from each other and begin to reset, causing the tension spring to retract. The tension spring then moves the lower base upwards until it is positioned at the lower... Once the base is reset, both bases can begin synchronous support. This lifting device achieves a step-by-step, gradual lifting action, with good overall load-bearing capacity and stable movement. If one hydraulic rod is damaged, leaks, or fails, the other hydraulic rod can compensate for its length, ensuring stability during the lifting process, preventing localized loss of control during lifting, and ensuring personnel safety. The use of two push blocks for lifting allows for stress relief through friction when both hydraulic rods fail, enabling a smooth descent. This prevents sudden support failure due to hydraulic rod failure during lifting and avoids sudden force on the tensioner, further enhancing safety and ensuring stable operation.

[0023] During use, the two mounting brackets move with the push block, causing the mounting brackets to change height and horizontal displacement with the push block. When the mounting brackets move, the first support plate carries the top or bottom safety seat to bear force, while the second support plate carries the sliding pin seat to slide on the inner wall of the support rail, so that the second support plate is only subjected to horizontal force. The second support plate, together with the first support plate, supports the top and bottom safety seats respectively. During climbing, the bottom safety seat is subjected to pressure, which allows it to climb with the help of the internal tensioner. At the same time, the top safety seat is supported and slides upward. At this time, the bottom safety seat cooperates with the base below for support, and the top safety seat cooperates with the base above to slide upward synchronously, so that they can work together for support and climbing sliding.

[0024] This design uses a tensioner that slides in a safety groove. The inner walls of the top safety seat, bottom safety seat, or limit slide are fixedly connected to the corresponding tensioner movable pin. The movable pin moves upward, causing the pressure component to deflect and press its pressure block into the safety groove, compressing its spring. When the movable pin is subjected to a downward force, the two pressure components exhibit an inclined support force. This, combined with the pressure block's tight fit within the safety groove, results in a greater support force and a greater compressive force to both sides. The two inclined support components are subjected to tension, which is simultaneously supported by the top safety seat, bottom safety seat, or limit slide, giving them extremely high support force.

[0025] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0036] like Figures 1 to 7 As shown, a building construction machine walking automatic lifting device includes a vertical guide rail 1, two bases 7 are slidably disposed on the surface of the vertical guide rail 1, a tension spring 9 is fixedly connected to the opposite surfaces of the two bases 7, and two hydraulic shear seats 6 slide together on the opposite surfaces of the two bases 7.

[0037] Two hydraulic shear seats 6 are fixed together on their surfaces with two cooperating frames 5. The two ends of the two cooperating frames 5 are respectively movably connected to a top safety seat 2 and a bottom safety seat 3.

[0038] The inner walls of the top safety seat 2, the bottom safety seat 3, and the two bases 7 are all equipped with tensioners 4 for preventing falls.

[0039] A platform base 11 is fixedly connected to the upper surface of the base 7. Two load-bearing sliding columns 10 are fixedly connected to one side of the platform base 11. The bottom end of the load-bearing sliding column 10 is fixedly connected to the upper surface of the upper base 7.

[0040] The design employs a step-by-step lifting mechanism, with two bases 7 working in conjunction with tension springs 9 and a hydraulic system to achieve alternating support and synchronous movement of the upper and lower bases 7. This design stably distributes the load, ensuring safety and stability during the lifting process and preventing the risk of localized lifting loss of control.

[0041] The system design takes into account potential damage, leakage, or failure of the hydraulic rods 62. If one hydraulic rod 62 fails, the other hydraulic rod 62 can compensate for its length, ensuring stability during the lifting process. Even if both hydraulic rods 62 fail simultaneously, the frictional force of the push block 63 can smoothly relieve the force, preventing sudden support failure and improving safety.

[0042] Specifically, such as Figure 5 As shown: The base 7 includes a limiting slide 73 that slides on the surface of the vertical guide rail 1. A seat body 71 is fixedly connected to the surface of the limiting slide 73. A limiting slide groove 72 that slides in cooperation with the hydraulic shear seat 6 is opened on the upper surface of the seat body 71. A pull bracket 74 is fixedly connected to one side of the seat body 71. The pull bracket 74 is fixedly connected to one end of the tension spring 9.

[0043] Specifically, such as Figure 2 and Figure 6 As shown: Two load-bearing slide bars 8 are fixed to the surface of the top safety seat 2, and the load-bearing slide column 10 is slidably disposed on the surface of the load-bearing slide bars 8.

[0044] Specifically, such as Figure 5 As shown: The hydraulic shear seat 6 includes a hydraulic seat 61 fixed to one side of the seat body 71. A hydraulic rod 62 is fixed through one side of the hydraulic seat 61. A push block 63 is fixedly connected to the telescopic end of the hydraulic rod 62. A limiting slide 64 is fixedly connected to the upper surface of the push block 63. The limiting slide 64 is slidably disposed on the inner wall of the limiting slide groove 72.

[0045] This design achieves mutual compression of the push blocks 63 under hydraulic pressure through the synchronous cooperation of two hydraulic shear seats 6. This design enables the lifting device to provide continuous and stable vertical support, and the staggered support height variation of the push blocks 63 ensures the balance and stability of the entire system.

[0046] Specifically, such as Figure 6 As shown: The vertical guide rail 1 includes two interlocking and pressing inclined support members 101. The two inclined support members 101 have a guide groove 102 on the side away from each other for sliding with the top safety seat 2, the bottom safety seat 3 and the two limiting slide seats 73. The two inclined support members 101 have a communicating safety groove 103 on one side. The tensioner 4 is slidably disposed on the inner wall of the safety groove 103.

[0047] Specifically, such as Figure 3 As shown: one side of the push block 63 is inclined, and the inclined surfaces of the push blocks 63 of the two hydraulic shear seats 6 are in a sliding contact state.

[0048] By using the inclined surface, it can achieve good support and lifting effects. When the hydraulic support fails, the inclined surface can reduce the force of the damaged hydraulic rod 62. In the traditional method, the hydraulic rod 62 is directly used for support. When the hydraulic rod 62 fails, the support force is still directly supported by the hydraulic rod 62. When the hydraulic rod 62 is damaged, there is a great safety hazard. Moreover, there are drawbacks to replacing or repairing the damaged hydraulic rod 62. This solution only needs to limit the push block 63, so that the hydraulic rod 62 can be disassembled, repaired or replaced while maintaining support.

[0049] Specifically, such as Figure 7 As shown: The tensioner 4 includes several movable pins 41. Two pressure members 42 are movably connected to the surface of each movable pin 41. One end of each pressure member 42 is movably connected to a pressure block 43 via a pin shaft. Several springs 44 are fixedly connected to the opposite surfaces of the two pressure blocks 43.

[0050] The top safety seat 2, bottom safety seat 3, and limit slide 73 have built-in tensioners 4, which achieve the anti-fall mechanism through the cooperation of sliding pin seat 54 and pressure block 43. When the tensioner 4 is subjected to supporting force, the pressure block 43 fits tightly against the inner wall of the safety groove 103, forming a reliable support and ensuring the safety and stability of the equipment during the lifting process.

[0051] Specifically, such as Figure 4 As shown: The collaborative frame 5 includes a mounting frame 51 fixedly connected to one side of the push block 63. A first support plate 52 is movably connected to the surface of the mounting frame 51 via a pin. A support slide rail 53 is fixedly connected to one side of the mounting frame 51. A sliding pin seat 54 is slidably limited on the inner wall of the support slide rail 53. A second support plate 55 is movably connected to the surface of the sliding pin seat 54.

[0052] The first support plate 52 and the second support plate 55 of the two cooperating frames 5 are movably connected to both sides of the top safety seat 2 and the bottom safety seat 3.

[0053] The movable connection of the coordinating frame 5, the first support plate 52, and the second support plate 55 enables stable support and sliding of the top safety seat 2 and the bottom safety seat 3 during height changes and horizontal displacement. This design ensures the coordinated operation of the support structure during climbing, improving the overall load-bearing capacity and travel stability of the equipment.

[0054] Specifically, such as Figure 6 As shown: The mating surfaces of the safety groove 103 and the pressure block 43 include, but are not limited to, flat surfaces, frosted surfaces, wavy surfaces, or oblique toothed surfaces that fit together.

[0055] The diverse designs (flat, frosted, wavy, or serrated) of the mating surfaces of the safety groove 103 and the pressure block 43 enhance friction, ensuring the reliability and safety of the support structure during the climbing process.

[0056] This design utilizes the cooperation of two hydraulic shear seats 6, causing the two push blocks 63 to press against each other under hydraulic pressure, providing continuous vertical support. The misalignment of the two push blocks 63 alters their relative support height, causing the lower base 7 to experience a downward force. Under the action of the internal tensioner 4, the lower base 7 is supported and limited, while the upper base 7 begins to move upward. At this point, the tensioner 4 slides against the inner wall of the safety groove 103. As the two push blocks 63 move away from each other, the upper base 7 loses its support force and, with the cooperation of the tensioner 4, begins to provide support. The two push blocks 63 then move away from each other and begin to reset, causing the tension spring 9 to retract. The tension spring 9 moves the lower base 7 upward until it resets, at which point the two bases 7 begin to provide synchronous support.

[0057] The tensioner 4 slides in the safety groove 103. The inner walls of the top safety seat 2, bottom safety seat 3, or limit slide 73 are fixedly connected to the corresponding movable pin 41 of the tensioner 4. The movable pin 41 moves upward, causing the pressure member 42 to deflect, so that its pressure block 43 fits into the safety groove 103, compressing its spring 44. When the movable pin 41 is subjected to a downward force, the two pressure members 42 exhibit an inclined support force. This, combined with the pressure block 43, tightly fits into the safety groove 103. The greater the support force it receives, the greater the squeezing force to both sides. The two inclined support members 101 are subjected to tension, and this tension is supported by the top safety seat 2, bottom safety seat 3, or limit slide 73.

[0058] During use, the two mounting brackets 51 move with the push block 63, causing the mounting brackets 51 to change height and horizontal displacement with the push block 63. When the mounting brackets 51 move, the first support plate 52 carries the top safety seat 2 or the bottom safety seat 3 to bear force, while the second support plate 55 carries the sliding pin seat 54 to slide on the inner wall of the support slide rail 53, so that the second support plate 55 is only subjected to horizontal force. The second support plate 55, together with the first support plate 52, supports the top safety seat 2 and the bottom safety seat 3 respectively. When climbing, the bottom safety seat 3 is subjected to pressure, which allows it to climb with the help of the internal tensioner 4. At the same time, the top safety seat 2 is supported and slides upward. At this time, the bottom safety seat 3 cooperates with the base 7 located below for support, and the top safety seat 2 cooperates with the base 7 located above to slide upward synchronously, so that they can cooperate to support and climb.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
