Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction jacking technology, and more specifically, it relates to a jacking device for building construction. Background Technology
[0002] When lifting existing buildings, the part of the lifting device that contacts the building needs to be fixed to prevent the building from shifting and causing danger during lifting; in addition, the lifting mechanism has only one lifting device, the contact area with the ground is small, and the lifting capacity is limited.
[0003] Patent publication number "CN222922836U" discloses a base with hydraulic cylinders installed on its top for lifting. The lifting end of each hydraulic cylinder is connected to a mounting plate, and the top of the mounting plate is connected to a supporting top plate. Positioning components for fixing and preventing the building to be lifted are located on both sides of the top of the supporting top plate. An annular positioning groove is formed on the top of the supporting top plate, and an adjustment component for rotating the building is installed inside the groove. A supporting top plate that assists in rotating the building is movably mounted on the top of the adjustment component's mounting plate, and a hydraulic rod is connected to the bottom of the supporting top plate. While this patent solves the problem of lifting buildings, it only allows for manual fixing of rectangular buildings. For other shapes, the clamping is unstable. Furthermore, during lifting, the wheels of the device are located at the bottom, and all the pressure is borne by the four wheels; excessive pressure can damage the wheels.
[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a building construction jacking device, which has multiple elastically extendable columns on the fixing mechanism. The telescopic columns that are in contact with the building will contract when subjected to force, while the non-contacting parts will surround the building to fix the building and prevent the building from shifting. This saves the time of manual fixing and saves more time and improves efficiency.
[0006] A building construction jacking device includes a moving mechanism, a lifting mechanism rotatably connected to the moving mechanism, and a fixing mechanism fixedly connected to the lifting mechanism. The moving mechanism includes a chassis, with two supports and two auxiliary supports fixedly connected to both ends of the chassis from the middle to the sides. The supports are inverted "L" shapes, and a spring is fixedly connected to the side of the support facing the chassis. A driven link is rotatably connected to one end of the auxiliary support, and a steering link is rotatably connected to the other end of the auxiliary support. The driven link includes components that cooperate with the auxiliary supports. The steering linkage includes a rotating hole 1, a platform 1 fixedly connected to one end of the driven link, a spring 1 fixedly connected to one end of the platform 1, a fixing bolt rotatably connected to the other end of the driven link, and a driven wheel fixedly connected to the fixing bolt. The steering linkage includes a rotating hole 2 that mates with the sub-support, a platform 2 fixedly connected to one end of the steering linkage, a spring 1 fixedly connected to the platform 2, and a rotating shaft rotatably connected to the other end of the steering linkage. A nut is screwed onto the upper end of the rotating shaft, and a steering wheel is rotatably connected to one side of the lower end of the rotating shaft.
[0007] Preferably, a rotating shaft ring is fixedly connected in the middle of the chassis, and a lifting mechanism is rotatably connected to the rotating shaft ring. The lifting mechanism includes a turntable rotatably connected to the rotating shaft ring, and four telescopic devices are fixedly connected to the turntable. The bottom oil inlet and outlet ports of the four telescopic devices are simultaneously sealed with a liquid pipe one, and the bottom oil inlet and outlet ports of the four telescopic devices are interconnected. The upper oil inlet and outlet ports of the four telescopic devices are simultaneously sealed with a liquid pipe two, and the upper oil inlet and outlet ports of the four telescopic devices are interconnected. The telescopic ends of the four telescopic devices are simultaneously fixedly connected with a fixing mechanism.
[0008] Preferably, the fixing mechanism includes a fixing box fixedly connected to the telescopic end of the telescopic device. The fixing box has multiple holes equidistantly opened. A second spring is fixedly connected in each hole. The bottom of the second spring abuts against the hole. A limit is fixedly connected to the upper part of the second spring. A telescopic column is fixedly connected to the upper part of the limit. An upper guard plate is fixedly connected above the fixing box. The upper guard plate has multiple holes to facilitate the passage of the telescopic column.
[0009] Preferably, the diameter of the limiting device is equal to the diameter of the hole on the fixing box, and the diameter of the telescopic column is smaller than the diameter of the limiting device.
[0010] Preferably, a trailer hitch is fixedly connected to one side of the chassis.
[0011] Preferably, the chassis is fixedly connected to the trailer hitch, bracket, and sub-bracket by welding.
[0012] Preferably, the steering wheel and the driven wheel are lockable wheels.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The fixing mechanism designed in this utility model consists of multiple telescopic columns that can extend and retract within a fixing box. When a building is placed on top, the telescopic columns that are in contact with the building will be compressed and descend, while the telescopic columns that are not in contact with the building will surround the building to fix it in place and prevent the building from shifting and causing danger. The fixing device designed in this utility model is suitable for lifting buildings of various shapes and does not require manual clamping, making it more convenient and faster.
[0014] 2. In the lifting process, the pressure of the moving mechanism designed in this utility model is initially transmitted to the steering wheel and driven wheel, and then to the driven link and steering link. This causes the springs connected to the driven link and steering link to stretch, which lowers the chassis. When the pressure is too high, the entire chassis contacts the ground, resulting in a larger contact area and a more stable lifting. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings: The directional terms used 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 based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0018] like Figures 1 to 9 As shown, a jacking device for building construction includes a moving mechanism 1, a lifting mechanism 2 rotatably connected to the moving mechanism 1, and a fixing mechanism 3 fixedly connected to the lifting mechanism 2. The moving mechanism 1 includes a chassis 101, with two supports 104 and two auxiliary supports 106 fixedly connected to both ends of the chassis 101 from the middle to the sides. The supports 104 are inverted "L" shapes, and a spring 105 is fixedly connected to the side of the support 104 facing the chassis 101. A driven link 108 is rotatably connected to one end of the auxiliary support 106, and a steering link 110 is rotatably connected to the other end of the auxiliary support 106. The driven link 108 includes components that cooperate with the auxiliary support 106. The rotating hole 1081 is connected to a platform 1082 at one end of the driven link 108. The platform 1082 is fixedly connected to one end of the spring 105. The other end of the driven link 108 is rotatably connected to a fixing bolt 1083. The fixing bolt 1083 is fixedly connected to the driven wheel 109. The steering link 110 includes a rotating hole 1101 that cooperates with the sub-support 106. The steering link 110 is fixedly connected to a platform 1102 at one end. The platform 1102 is fixedly connected to the spring 105. When the spring 105 is not raised, it can raise the entire device so that it is close to the steering wheel 107 and the driven wheel 109 and ground. The other end of the steering linkage 110 is fixedly connected to a pivot hole 1103, and a pivot shaft 1071 is rotatably connected in the pivot hole 1103. A nut 1104 is screwed onto the upper end of the pivot shaft 1071, and a steering wheel 107 is rotatably connected to one side of the lower end of the pivot shaft 1071. The steering wheel 107 can rotate freely, driving the steering of this utility model.
[0019] A rotating shaft ring 103 is fixedly connected to the center of the chassis 101, and a lifting mechanism 2 is rotatably connected to the rotating shaft ring 103. The lifting mechanism 2 can rotate on the chassis 101 to steer the building. Figure 5As shown, the lifting mechanism 2 includes a turntable 201 rotatably connected to a rotating shaft ring 103. The turntable 201 has a shaft at its bottom, which can be installed inside the rotating shaft ring 103 to achieve rotation. Four telescopic devices 203 are fixedly connected to the turntable 201. A hydraulic pipe 202 is simultaneously sealed to the bottom oil inlet and outlet ports of the four telescopic devices 203. The bottom oil inlet and outlet ports of the four telescopic devices 203 are interconnected. A hydraulic pipe 204 is simultaneously sealed to the upper oil inlet and outlet ports of the four telescopic devices 203. The upper oil inlet and outlet ports of the four telescopic devices 203 are interconnected. A fixing mechanism 3 is fixedly connected to the telescopic ends of the four telescopic devices 203. The telescopic devices 203 used in this invention are hydraulic telescopic cylinders. The upper and lower oil inlet and outlet ports of the four telescopic devices 203 are connected to each other, allowing for simultaneous telescopic movement and preventing uneven telescopic movement that could lead to tilting and potential danger.
[0020] like Figures 6 to 9 As shown, the fixing mechanism 3 includes a fixing box 303 fixedly connected to the telescopic end of the telescopic device 203. The fixing box 303 has multiple holes 3031 equidistantly spaced. A second spring 304 is fixedly connected to each hole 3031, with its bottom abutting against the hole 3031. A limit 305 is fixedly connected to the upper part of the second spring 304, and a telescopic column 301 is fixedly connected to the upper part of the limit 305. An upper guard plate 302 is fixedly connected above the fixing box 303, and the upper guard plate 302 has multiple holes to facilitate the passage of the telescopic column 301. The advantage of this design is that when a building falls on the telescopic column 301, the compressed portion of the telescopic column 301 will retract downwards, while the uncompressed portion remains intact around the building, thus restricting its lateral movement.
[0021] The diameter of the limit switch 305 is equal to the diameter of the hole 3031 on the fixing box 303, while the diameter of the telescopic column 301 is smaller than the diameter of the limit switch 305. The advantage of this design is that the telescopic column 301 can move freely within the hole 3031 without moving out, as it will be blocked by the limit switch 305 and the upper guard plate 302. A trailer hitch 102 is fixedly connected to one side of the chassis 101. It can be moved by pulling from behind the vehicle or by towing with a rope. The chassis 101 is fixedly connected to the trailer hitch 102, the bracket 104, and the sub-bracket 106 by welding. This welding method makes the structure more stable. The steering wheel 107 and the driven wheel 109 are lockable wheels. The advantage of using lockable wheels is that when the device is moved to a suitable position, the steering wheel 107 and the driven wheel 109 will not move during lifting operations.
[0022] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.
[0023] Working process: After moving the device to the required location on the construction site using the trailer hook 102, lock the steering wheel 107 and driven wheel 109 to fix the device in place. By placing the building on top of the fixing mechanism 3, the telescopic column 301 on the fixing mechanism 3 is compressed and begins to press down on the column spring 304. The telescopic columns 301 that are not compressed by the building surround the building, playing a role in fixing the building and preventing the building from moving left or right during the lifting process.
[0024] Then the telescopic device 203 in the lifting mechanism 2 is activated. The telescopic end of the telescopic device 203 is continuously raised. At the beginning, the steering wheel 107 and driven wheel 109 at the bottom are subjected to force, and the force is transmitted to the steering linkage 110 and driven linkage 108 respectively. The steering linkage 110 and driven linkage 108 then transmit the force to the spring 105, causing the steering linkage 110 and driven linkage 108 to rotate. The chassis 101 continuously descends until it contacts the ground. Then the telescopic end of the telescopic device 203 continues to extend and retract upward, lifting the building.
[0025] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. 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.
