Description

Technical Field

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

[0002] In building construction, a lifting device is an important tool for material handling, and its safety and efficiency are directly related to the smooth progress of the entire construction process. Although traditional lifting devices for building construction meet the construction requirements to a certain extent, many deficiencies are still exposed in actual applications.

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

[0004] Secondly, indoor lifting devices are often transported to the designated location in parts and then assembled for use, and generally use expansion bolts or place heavy objects to fix the lifting device. The former fixing method using expansion bolts not only damages the building, but also requires a large amount of working time for drilling before installing the expansion bolts. The latter fixing method of placing heavy objects, if the weight of the placed heavy object is insufficient and the center of gravity shifts, or even overturns, will cause personal or property losses.

Detailed implementation mode

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] In the paragraphs of detailed description, the orientation nouns involved are only for the convenience of those skilled in the art to understand the technical solutions recorded in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] As Figures 1 to 4As shown in the figure, a hoisting device for building construction with high safety includes a vehicle body 100, a hoisting platform 101, a support structure 200, an adaptive counterweight section 300, and a side support structure 400. A plurality of the support structures 200 are provided and are movably embedded on the outer side wall of the vehicle body 100, and a telescopic anchoring component 240 is installed in the support structure 200; the adaptive counterweight section 300 is arranged on one side of the vehicle body 100 and is movably connected to the vehicle body 100; a plurality of the side support structures 400 are installed and are fixedly connected to the vehicle body 100; the hoisting 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 supporting the vehicle body 100 during outdoor operations, and the side support structure 400 is used for supporting the vehicle body 100 during indoor operations. In this way, when the hoisting device needs to perform hoisting work outdoors, first extend the assembled support structure 200 and ensure that the end facing the ground is in close contact with the ground. When the support structure 200 is in close contact with the ground, the anchoring component 240 assembled inside it continues to press towards the ground until the anchoring component 240 is completely embedded in the ground. In this way, the hoisting device effectively improves the connection strength between the device and the ground by relying on the anchoring component 240, thereby improving the safety of the hoisting device during the working process and making it not easy to overturn during hoisting. At the same time, the adaptive counterweight section 300 can automatically adjust the distance from the vehicle body 100 according to the change of the center of gravity of the hoisting device during the working process of the hoisting device, so as to achieve the purpose of real-time adjustment of the hoisting device, and further improve the safety of the hoisting device. When the device is performing indoor hoisting work, first move the equipment to an appropriate position so that the side support structure 400 on one side is located on one side of the building beam. Then, extend the side support structure 400 fixed on the periphery of the vehicle body 100 so that the bottom and top of the side support structure 400 are in close contact with the indoor ground and the inner side of the roof or beam respectively. Thus, the hoisting device can maintain stability by relying on the connection between the side support structure 400 and the inner wall of the building, effectively improving the safety of the hoisting device during the working process and making it not easy to overturn during the work.

[0034] Optionally, a plurality of embedding grooves 102 are provided on the periphery of the vehicle body 100, and slide rails 103 are provided on opposite sides of the embedding grooves 102, and one of the slide rails 103 is communicated with the inside of the vehicle body 100. In this way, the support structure 200 can be completely received inside the side wall of the vehicle body 100 through the provided embedding grooves 102. At the same time, through the provided slide rails 103, the support structure 200 can slide stably in the embedding grooves 102, making it not easy to deviate during the sliding process, thereby improving the running stability of the support structure 200.

[0035] Optionally, a towing frame 104 is installed on one side of the vehicle body 100. In this way, the lifting device can be connected to a towing tool such as an engineering vehicle through the towing frame 104 to move the lifting device. Thereby, the usage flexibility of the lifting device is improved.

[0036] Optionally, a control panel, a fuel generator, a storage battery, and a hydraulic press are also installed inside the vehicle body 100. In this way, the built-in fuel generator and the storage battery 242 can provide power support for the hydraulic mechanism and other electric drive components to ensure the working stability of the lifting device. At the same time, the control panel monitors data such as the operating state and the center-of-gravity attitude of the device in real time and makes adaptive adjustments in a timely manner. For example, when the control panel monitors the center of gravity of the lifting device during operation in real time, when the center of gravity changes, it automatically adjusts the distance between the self-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, the operating stability and safety of the lifting device are improved.

[0037] Such as Figure 5As shown in the figure, the support structure 200 includes a driving assembly 210, a first connecting frame 220, a second connecting frame 221, a hydraulic support column 230, and an anchoring 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 one 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 driving assembly 210 installed inside the vehicle body 100. The hydraulic support column 230 is composed of a housing 231 and a telescopic section 232. One end of the telescopic section 232 is embedded in the housing 231, and the other end protrudes out of the housing 231. The end of the telescopic section 232 embedded in the housing 231 defines the internal space of the housing 231 into a first hydraulic chamber 233 and a second hydraulic chamber 234. And a pressure-bearing shell 235 fixed to the telescopic section 232 is installed in the first hydraulic chamber 233. Wherein, a plurality of through holes 236 penetrating from one end to the other end are provided on the telescopic section 232. Part of the anchoring assembly 240 is installed in the pressure-bearing shell 235, and part of the components are installed in the telescopic section 232 and are movably connected to the telescopic section 232. In this way, the hydraulic support column 230 is accommodated on both sides of the vehicle body 100 through the mutual 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, not only reduces the overall volume of the vehicle body 100, but also improves the utilization rate of the internal space of the vehicle body 100, enabling the vehicle body 100 to install other devices or components in a limited space. At the same time, the driving assembly 210 installed inside the vehicle body 100 is connected to the second connecting frames 221 installed on both sides of the vehicle body 100 at the same time, and forms a linkage through the second connecting frame 221, the first connecting frame 220 and the hydraulic support column 230, so as to achieve the purpose of driving multiple support 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 support structure 200. At the same time, it also improves the operating stability of the support structure 200, enabling multiple support structures 200 to maintain a synchronous operating state to ensure that the support points where the support structures 200 are located are consistent, avoiding the occurrence of the situation of center of gravity deviation caused by inconsistent support points, and effectively improving the operating stability of the lifting device.

[0038] Optionally, sliders 222 adapted to the slide rail 103 are provided at the ends of the first connecting frame 220 and the second connecting frame 221, 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 sliders 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 following the driving assembly 210, avoiding jamming due to the inability of the slider 222 connected to the driving assembly 210 to rotate. Thereby, the operating stability of the support structure 200 is improved.

[0039] Such as Figure 6 And Figure 7As shown, the anchoring 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-bearing housing 235 from top to bottom. The threaded rod 244 is embedded in the telescopic joint 232, and one end thereof passes through the telescopic joint 232 and protrudes into the pressure-bearing housing 235 to be 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 thereof 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 anchoring 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 anchoring assembly 240 can be driven by the cooperation of 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 towards the ground. During the movement of the anchor head 245, the anchor plate 246 hinged on the side wall of the anchor head 245 gradually disengages from the outer shell of the hydraulic support column 230. Under the action of the spring 2452, the end of the anchor plate 246 away from the hinge point with the anchor head 245 pops out towards the direction away from the anchor head 245, and during the continuous movement of the anchor head 245, the anchor plate 246 is embedded in the soil, so as to achieve the purpose of anchoring, effectively improving the connection strength between the hydraulic support column 230 and the ground, making it difficult for the lifting device to tip over during the lifting process, and thus improving the safety of the lifting device. On the contrary, when the lifting work is completed, the anchor head 245 is driven by the cooperation of the circuit board 241, the battery 242, and the high-torque motor 243 to gradually retract into the telescopic joint 232. When the anchor head 245 retracts to the hinge 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. With the continuous retraction movement of the anchor head 245, the anchor plate 246 is gradually retracted into the slot 2451 under the extrusion of the telescopic joint 232 until the anchor head 245 is completely retracted into the telescopic joint 232. At this time, the anchoring assembly 240 is disengaged from the ground anchoring state.

[0040] As Figure 7 and Figure 8As shown, one end of the through hole 236 is provided with a first contact 237, and one end of the first contact 237 protrudes outside the telescopic section 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, when it is completely embedded in the side wall of the vehicle body 100, the first contact 237 contacts the second contact, so as to achieve the purpose of charging the battery 242, so as to drive the anchoring assembly 240 for the next use.

[0041] As Figure 8 As shown, the first contact 237 includes a contact terminal 2371, a closed sleeve 2372, a limit ring 2373, and a return spring 2374. The contact terminal 2371 is embedded in the through hole 236, and a limit protrusion 2375 surrounding it is provided on its outer side wall; the closed sleeve 2372 is installed at the edge of the through hole 236, and the contact terminal 2371 protrudes from one end of the closed sleeve 2372 to the other end; the limit ring 2373 is fixed in the through hole 236; the return spring 2374 is sleeved on the outer side wall of the contact terminal 2371 and is located between the limit protrusion 2375 and the limit ring 2373. In this way, when the contact terminal 2371 contacts the second contact, it can rely on the elastic action of the return spring 2374 to make the contact terminal 2371 closely contact the second contact, so that it is not easy to have a virtual connection phenomenon during the contact process between the two. Thus, it not only improves the stability of the battery 242 during charging, but also reduces the impact on the battery 242 and the circuit board 241 due to virtual connection, effectively improving the service life of the battery 242 and the circuit board 241.

[0042] As Figure 9 As shown, the driving assembly 210 includes a driving motor 211, a scroll gear 212, a lead screw 213, and a connecting plate 214. The driving motor 211 is fixed in the vehicle body 100, and scroll gears 212 are installed at the power output ends of both ends thereof; a plurality of lead screws 213 are provided, arranged in parallel in the vehicle body 100, adjacent to the second connecting frame 221, and meshed with the scroll gear 212; a plurality of connecting plates 214 are provided, one end of which is connected to the lead screw 213, and the other end protrudes outside the vehicle body 100 and is movably connected to the second connecting frame 221; among them, one end of the connecting plate 214 connected to the lead screw 213 is a right-handed thread, and the other is a left-handed thread. In this way, when the lead screw 213 rotates driven by the driving motor 211 and the scroll gear 212, the connecting plates 214 provided with right-handed and left-handed threads can move synchronously in opposite or reverse directions while the lead screw 213 rotates. It not only realizes the purpose of driving a single driving motor 211 to drive multiple connecting plates 214 to move synchronously, but also ensures the movement consistency of the multiple connecting plates 214, thereby improving the support stability of the support structure 200 and the operation safety of the lifting device.

[0043] As Figure 10 and Figure 11 shown, the adaptive counterweight section 300 includes a counterweight box 301, a support wheel 302, a connecting rod 303, and an adjusting rod 304. A plurality of connecting rods 303 are provided. One end of each connecting rod 303 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 inside the counterweight box 301. The support wheel 302 is installed at the bottom of the counterweight box 301, and a plurality of support springs 305 are installed between the support wheel 302 and the counterweight box 301. In this way, under the elastic action of the support springs 305, the support wheel 302 installed at the bottom of the counterweight box 301 can still be in contact with the ground in a state where the vehicle body 100 is jacked up by the support structure 200, so as to achieve the effect of providing mobile support for the support of the counterweight box 301. The influence of the gravity of the counterweight box 301 on the connecting rod 303 and the adjusting rod 304 is reduced. On the one hand, the service life of the connecting rod 303 and the adjusting rod 304 is prolonged, and on the other hand, the coherence of the real-time adjustment of the connecting rod 303 and the adjusting rod 304 to the counterweight box 301 is improved.

[0044] As Figure 11 shown, a loading cavity 3011 is provided inside the counterweight box 301. In this way, the loading cavity 3011 can be used to fill counterweight objects, including but not limited to sand and gravel, water.

[0045] As Figure 12 shown, the side support structure 400 includes a first vertical rod 410, a second vertical rod 420, and a diagonal brace 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 opposite side of the vehicle body 100. The diagonal brace 430 is installed on one side of the vehicle body 100. One end of the diagonal brace 430 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 brace 430. In this way, after the first vertical rod 410 and the second vertical rod 420 extend, they can respectively abut against the ground and the roof 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 abuts against the side wall of the cross beam of the building. With the cooperation of the diagonal brace 430, a triangular force-bearing structure is formed among the first vertical rod 410, the diagonal brace 430, and the vehicle body 100, providing a lateral support force for the vehicle body 100. Therefore, with the cooperation of the first vertical rod 410, the second vertical rod 420, and the diagonal brace 430, the vehicle body 100 can maintain stability during operation, so that the vehicle body 100 is not prone to tipping over during the lifting operation, thereby improving the working safety of the lifting equipment.

[0046] As Figure 13As shown, the structures of the first vertical rod 410 and the second vertical rod 420 are the same, including a driving machine 421, an upper ejector rod 422, and a lower ejector rod 423. Power output ends are provided on both sides of the driving machine 421, one end of which is connected to the upper ejector rod 422, and the other end is connected to the lower ejector rod 423. The length of the upper ejector rod 422 is greater than that of the lower ejector rod 423, and contact top plates 424 are provided at the ends of the upper ejector rod 422 and the lower ejector rod 423 away from the driving machine 421. In this way, since the contact distance between the lower ejector rod 423 and the ground is less than the contact distance between the upper ejector rod 422 and the roof, the length of the upper ejector rod 422 is greater than that of the lower ejector rod 423, and the upper ejector rod 422 is a multi-section telescopic structure 4221, so as to obtain a longer telescopic distance. In addition, the upper ejector rod 422 and the lower ejector rod 423 can increase the contact area with the roof or the ground by relying on the contact top plates 424, thereby improving the working stability of the vehicle body 100 during lifting work, and further improving the working safety of the lifting device.

[0047] Optionally, on one side of the contact top plate 424 at one end of the upper ejector rod 422, a hinge ear 4241 adapted to the diagonal brace 430 is provided, and a side contact plate 4242 is provided on the other side opposite thereto.

[0048] Finally, although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
