Description

Technical Field

[0001] The present invention belongs to the technical field of lifting equipment, and in particular, relates to a lifting device for construction with high safety. Background Art

[0002] In construction, lifting devices are important tools for material handling, and their safety and efficiency are directly related to whether the entire construction process can proceed smoothly. Although traditional lifting devices for construction meet the needs of construction to a certain extent, they still expose many shortcomings in practical applications.

[0003] First, the applicability of traditional lifting devices is poor and they can only work in a single environment, either outdoor or indoor. For example, outdoor lifting devices cannot enter indoors for lifting operations. At the same time, the support device of the outdoor lifting device can only rely on the support position and the weight of the device to increase the stability of the lifting device. When lifting a large weight, it will cause the center of gravity to change and cause it to overturn, resulting in the general safety of traditional lifting devices.

[0004] Secondly, indoor lifting devices are often transported to designated locations in parts for assembly and use, and are generally fixed with expansion bolts or heavy objects. The former uses expansion bolts to fix the device, which not only damages the building, but also requires a lot of work time to drill holes before installing the expansion bolts. The latter uses heavy objects to fix the device. If the weight of the placed heavy objects is insufficient and the center of gravity is offset, it may even overturn, resulting in loss of life or property. Summary of the invention

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings: The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0019] like Figures 1 to 4As shown, a highly safe lifting device for construction includes a vehicle body 100, a lifting platform 101, a support structure 200, an adaptive counterweight section 300, and a side support structure 400. The support structure 200 is provided in plurality and embedded in the outer wall of the vehicle body 100 in a movable manner, and a telescopic anchor assembly 240 is installed in the support structure 200; the adaptive counterweight section 300 is provided on one side of the vehicle body 100 and is movably connected to the vehicle body 100; the side support structure 400 is provided in plurality and is fixedly connected to the vehicle body 100; the lifting platform 101 is installed on one side of the vehicle body 100; wherein, the support structure 200 and the adaptive counterweight section 300 are used for outdoor operation support of the vehicle body 100, and the side support structure 400 is used for indoor operation support of the vehicle body 100. In this way, when the lifting device needs to perform lifting work outdoors, the assembled support structure 200 is first extended, and its end facing the ground is ensured to be in close contact with the ground. When the support structure 200 is in close contact with the ground, the anchor assembly 240 assembled inside it continues to push toward the ground until the anchor assembly 240 is completely embedded in the ground. In this way, the lifting device relies on the anchor assembly 240 to effectively improve the connection strength between the device and the ground, thereby improving the safety of the lifting device during operation and making it less likely to overturn during the lifting process. At the same time, the adaptive counterweight section 300 can automatically adjust the distance between the vehicle body 100 according to the change of the center of gravity of the lifting device during the operation of the lifting device, thereby achieving the purpose of real-time adjustment of the lifting device, further improving the safety of the lifting device. When the device is located in the indoor lifting work, first move the equipment therein to an appropriate position so that the side support structure 400 on one side is located on one side of the building beam. Then, the side support structure 400 fixed on the side of the vehicle body 100 is extended so that the bottom and top of the side support structure 400 are respectively in close contact with the indoor ground and the roof or the inner side of the beam. Thus, the lifting device can remain stable by relying on the connection between the side support structure 400 and the inner wall of the building, which effectively improves the safety of the lifting device in the working project and makes it less likely to overturn during work.

[0020] Optionally, a plurality of embedding grooves 102 are provided on the circumference of the vehicle body 100, and slide rails 103 are provided on opposite sides of the embedding grooves 102, wherein the slide rail 103 on one side is in communication with the interior of the vehicle body 100. In this way, the support structure 200 can be completely received in the side wall of the vehicle body 100 through the embedded grooves 102. At the same time, the support structure 200 can slide stably in the embedded grooves 102 through the slide rails 103, so that it is not easy to deviate during the sliding process, thereby improving the operation stability of the support structure 200.

[0021] Optionally, a traction frame 104 is installed on one side of the vehicle body 100. In this way, the lifting device can be connected to a traction tool such as an engineering vehicle through the traction frame 104 to move the lifting device, thereby improving the use flexibility of the lifting device.

[0022] Optionally, a control panel, a fuel generator, a battery and a hydraulic press are also installed in the vehicle body 100. In this way, the built-in fuel generator and the battery 242 can provide power support to the hydraulic mechanism and other electric drive components to ensure the working stability of the lifting device. At the same time, the operating status, center of gravity posture and other data of the equipment are monitored in real time through the control panel, and adaptive adjustments are made in time. For example, when the control panel monitors the center of gravity of the lifting device in real time when it is working, when the center of gravity changes, it automatically adjusts the distance between the adaptive counterweight section 300 and the vehicle body 100 to ensure that the center of gravity of the lifting device is always within a controllable range. Thereby improving the operating stability and safety of the lifting device.

[0023] like Figure 5As shown, the support structure 200 includes a drive assembly 210, a first connecting frame 220, a second connecting frame 221, a hydraulic support column 230, and an anchor assembly 240. One end of the first connecting frame 220 is hinged to the vehicle body 100, and the other end is rotatably connected to the hydraulic support column 230; one end of the second connecting frame 221 is slidably connected to the vehicle body 100, and the other end is rotatably connected to the hydraulic support column 230, and the end of the second connecting frame 221 connected to the vehicle body 100 partially protrudes into the vehicle body 100 and is connected to the drive assembly 210 installed in the vehicle body 100; the hydraulic support column 230 It is composed of a shell 231 and a telescopic joint 232, one end of the telescopic joint 232 is embedded in the shell 231, and the other end protrudes out of the shell 231. The end of the telescopic joint 232 embedded in the shell 231 defines the internal space of the shell 231 as a first hydraulic chamber 233 and a second hydraulic chamber 234, and a pressure-bearing shell 235 fixed to the telescopic joint 232 is installed in the first hydraulic chamber 233; wherein the telescopic joint 232 is provided with a plurality of through holes 236 extending from one end to the other end; the anchor assembly 240 is partially installed in the pressure-bearing shell 235, and part of the assembly is installed in the telescopic joint 232, and is movably connected to the telescopic joint 232. In this way, the hydraulic support column 230 is accommodated on both sides of the vehicle body 100 through the cooperation of the first connecting frame 220 and the second connecting frame 221. Compared with the traditional embedded hydraulic structure, it does not occupy the internal space of the vehicle body 100, which not only reduces the overall volume of the vehicle body 100, but also improves the internal space utilization rate of the vehicle body 100, so that the vehicle body 100 can install other equipment or components in a limited space. At the same time, the driving assembly 210 installed in the vehicle body 100 is simultaneously connected to the second connecting frame 221 installed on both sides of the vehicle body 100, and is linked with the first connecting frame 220 and the hydraulic support column 230 through the second connecting frame 221, thereby achieving the purpose of driving multiple supporting structures 200 to operate with one set of driving assembly 210, which not only simplifies the structure of the driving assembly 210 to improve the operating stability of the supporting structure 200. At the same time, the operating stability of the supporting structure 200 is also improved, so that multiple supporting structures 200 can maintain a synchronous operating state to ensure that the supporting points of the supporting structures 200 are consistent, avoid the occurrence of the center of gravity shift due to inconsistent supporting points, and effectively improve the operating stability of the lifting device.

[0024] Optionally, the ends of the first connecting frame 220 and the second connecting frame 221 are both provided with a slider 222 adapted to the slide rail 103, wherein the slider 222 provided at one end of the second connecting frame 221 is rotatably connected to the second connecting frame 221. In this way, the first connecting frame 220 and the second connecting frame 221 can cooperate with the slide rail 103 through the slider 222 to improve the sliding stability of the first connecting frame 220 and the second connecting frame 221. At the same time, the rotatable slider 222 provided at one end of the second connecting frame 221 is used to connect the driving assembly 210. In this way, after the rotatable slider 222 is connected to the driving assembly 210, it can automatically adjust the rotation angle when moving with the driving assembly 210, avoiding the slider 222 connected to the driving assembly 210 from being stuck due to the inability to rotate. Thereby, the stability of the operation of the support structure 200 is improved.

[0025] like Figure 6 and Figure 7As shown, the anchor assembly 240 includes a circuit board 241, a battery 242, a high-torque motor 243, a threaded rod 244, an anchor head 245, and an anchor plate 246. The circuit board 241, the battery 242, and the high-torque motor 243 are sequentially installed in the pressure shell 235 from top to bottom; the threaded rod 244 is embedded in the telescopic joint 232, one end of which passes through the telescopic joint 232 and protrudes into the pressure shell 235 and is fixedly connected to the power output end of the high-torque motor 243; the anchor head 245 is embedded in the telescopic joint 232, one end of which is connected to the threaded rod 244, and a plurality of slots 2451 are provided on the side wall of the anchor head 245; the number of the anchor plates 246 is the same as the number of the slots 2451, and one end of the anchor plate 246 is hinged to the inner wall of the slot 2451; wherein a spring 2452 is installed on the side of the anchor plate 246 facing the slot 2451. In this way, the anchor assembly 240 connected to the telescopic joint 232 can move synchronously with the telescopic joint 232. When one end of the telescopic joint 232 contacts the ground, the anchor head 245 of the anchor assembly 240 can be driven by the circuit board 241, the battery 242 and the high-torque motor 243, so that the anchor head 245 gradually protrudes out of the telescopic joint 232 and continues to move toward the ground. During the movement of the anchor head 245, the anchor plate 246 hinged on the side wall of the anchor head 245 is gradually separated from the outer shell of the hydraulic support column 230. Under the action of the spring 2452, the anchor plate 246 moves away from one end of the hinge point with the anchor head 245 and pops out in the direction away from the anchor head 245. During the continuous movement of the anchor head 245, the anchor plate 246 is embedded in the soil, thereby achieving the purpose of anchoring, effectively improving the connection strength between the hydraulic support column 230 and the ground, making it less likely for the lifting device to overturn during the lifting process, thereby improving the safety of the lifting device. On the contrary, when the lifting work is completed, the anchor head 245 is driven by the circuit board 241, the battery 242 and the high-torque motor 243 to gradually retract the anchor head 245 into the telescopic joint 232. When the anchor head 245 is retracted to the hinged position of the anchor plate 246 and the anchor head 245, the outer wall of the anchor plate 246 abuts against the telescopic joint 232. As the anchor head 245 continues to retract, the anchor plate 246 is squeezed by the telescopic joint 232 and gradually retracts into the slot 2451 until the anchor head 245 is completely retracted into the telescopic joint 232. At this time, the anchor assembly 240 is released from the anchoring state with the ground.

[0026] like Figure 7 and Figure 8As shown, a first contact 237 is installed at one end of the through hole 236, and one end of the first contact 237 protrudes out of the telescopic joint 232, and the other end is connected to a cable 238 connected to the circuit board 241; a second contact adapted to the first contact 237 is provided on the side wall of the vehicle body 100. In this way, when the hydraulic support column 230 is in a non-working state, that is, completely embedded in the side wall of the vehicle body 100, the first contact 237 contacts the second contact, thereby achieving the purpose of charging the battery 242, so as to drive the anchor assembly 240 for the next use.

[0027] like Figure 8 As shown, the first contact 237 includes a contact terminal 2371, a sealing sleeve 2372, a limiting ring 2373, and a reset spring 2374. The contact terminal 2371 is embedded in the through hole 236, and a limiting protrusion 2375 surrounding the contact terminal is provided on the outer wall thereof; the sealing sleeve 2372 is installed at the edge of the through hole 236, and the contact terminal 2371 protrudes from one end of the sealing sleeve 2372 to the other end; the limiting ring 2373 is fixed in the through hole 236; the reset spring 2374 is sleeved on the outer wall of the contact terminal 2371, and is located between the limiting protrusion 2375 and the limiting ring 2373. In this way, when the contact terminal 2371 contacts the second contact, the elastic action of the reset spring 2374 can be relied on to make the contact terminal 2371 closely contact the second contact, so that it is not easy for the two to have a virtual connection during the contact process. This not only improves the stability of the battery 242 during the charging process, but also reduces the impact of the virtual connection on the battery 242 and the circuit board 241, effectively increasing the service life of the battery 242 and the circuit board 241.

[0028] like Fig. 9 As shown, the driving assembly 210 includes a driving motor 211, a volute gear 212, a screw rod 213, and a connecting plate 214. The driving motor 211 is fixed in the vehicle body 100, and the power output ends at both ends thereof are both installed with a volute gear 212; there are a plurality of screw rods 213, which are arranged in parallel in the vehicle body 100, adjacent to the second connecting frame 221, and meshed with the volute gear 212; there are a plurality of connecting plates 214, one end of which is connected to the screw rod 213, and the other end protrudes out of the vehicle body 100 and is movably connected to the second connecting frame 221; wherein, one end of the connecting plate 214 connected to the screw rod 213 is a positive thread, and the other is a reverse thread. In this way, when the screw rod 213 is driven by the driving motor 211 and the volute gear 212 to rotate, the connecting plate 214 with positive thread and reverse thread is provided, so that it can move synchronously in opposite or reverse directions while the screw rod 213 rotates. It not only realizes the purpose of using a single drive motor 211 to drive multiple connecting plates 214 to move synchronously, but also ensures the movement consistency of multiple connecting plates 214, thereby improving the supporting stability of the supporting structure 200 and the operating safety of the lifting device.

[0029] like Fig.10 and Fig.11 As shown, the adaptive counterweight section 300 includes a counterweight box 301, a support wheel 302, a connecting rod 303, and an adjusting rod 304. There are a plurality of connecting rods 303, one end of which is fixedly connected to the counterweight box 301 and the other end is movably connected to the vehicle body 100; one end of the adjusting rod 304 is fixedly connected to the counterweight box 301, and the other end passes through the side wall of the vehicle body 100 and protrudes into the vehicle body 100; a loading cavity is provided in the counterweight box 301; the support wheel 302 is installed at the bottom of the counterweight box 301, and a plurality of supporting springs 305 are installed between the support wheel 302 and the counterweight box 301. In this way, the support wheel 302 installed at the bottom of the counterweight box 301 can still contact the ground under the elastic action of the supporting spring 305 even when the vehicle body 100 is lifted by the supporting structure 200, thereby achieving the function of supporting the counterweight box 301 for mobile support. The influence of the gravity of the counterweight box 301 on the connecting rod 303 and the adjusting rod 304 is reduced, which on the one hand increases the service life of the connecting rod 303 and the adjusting rod 304, and on the other hand improves the consistency of the connecting rod 303 and the adjusting rod 304 in real-time adjustment of the counterweight box 301.

[0030] like Fig.11 As shown, a loading chamber 3011 is provided in the ballast box 301. In this way, the loading chamber 3011 can be used to fill ballast objects, including but not limited to sand and gravel, water.

[0031] like Fig.12 As shown, the side support structure 400 includes a first vertical rod 410, a second vertical rod 420, and a diagonal support 430. The first vertical rod 410 is fixed on one side of the vehicle body 100, and the second vertical rod 420 is fixed on the other side of the vehicle body 100 opposite thereto. The diagonal support 430 is installed on one side of the vehicle body 100, one end of which is hinged to the vehicle body 100, and the other end is hinged to the first vertical rod 410, and a locking wrench 431 is installed on the side wall of the diagonal support 430. In this way, the first vertical rod 410 and the second vertical rod 420 can respectively contact the ground and the roof after being extended, so as to achieve the longitudinal support force for the vehicle body 100. At the same time, the end of the first vertical rod 410 facing the roof also contacts the side wall of the cross beam of the building, and with the cooperation of the diagonal support 430, a triangular force structure is formed between the first vertical rod 410, the diagonal support 430 and the vehicle body 100, providing the lateral support force for the vehicle body 100. Therefore, with the cooperation of the first vertical pole 410, the second vertical pole 420 and the diagonal brace 430, the vehicle body 100 can remain stable in the working state, so that the vehicle body 100 is not easy to overturn during the lifting operation, thereby improving the working safety of the lifting equipment.

[0032] like Fig.13As shown, the first vertical rod 410 and the second vertical rod 420 have the same structure, including a driving machine 421, an upper push rod 422, and a lower push rod 423. Both sides of the driving machine 421 are provided with power output ends, one end of which is connected to the upper push rod 422, and the other end is connected to the lower push rod 423, wherein the length of the upper push rod 422 is greater than the length of the lower push rod 423, and the upper push rod 422 and the lower push rod 423 are both provided with a contact top plate 424 at one end away from the driving machine 421. In this way, because the contact distance between the lower push rod 423 and the ground is less than the contact distance between the upper push rod 422 and the roof, the length of the upper push rod 422 is greater than the length of the lower push rod 423, and the upper push rod 422 is a multi-section telescopic structure 4221, thereby obtaining a longer telescopic distance. In addition, the upper push rod 422 and the lower push rod 423 can increase the contact area with the roof or the ground by relying on the contact top plate 424, thereby improving the stability of the vehicle body 100 in lifting work, and further improving the working safety of the lifting device.

[0033] Optionally, a contact top plate 424 located at one end of the upper push rod 422 is provided with a hinge ear 4241 adapted to the diagonal support 430 on one side, and a side contact plate 4242 is provided on the other side opposite thereto.
