Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to an integrated support and lifting device. Background Technology

[0002] The "building machine" mainly consists of a lifting and support system, a steel platform system, a hanging frame system, a formwork system, and ancillary facilities system. It is a multi-level work platform that integrates construction machinery and material storage yards. Its main components are constructed using standardized, prefabricated Bailey panels or steel profiles to form the platform, with suspended hanging frames for the operating layer. The turnover rate of various components is high, which reduces costs while improving applicability.

[0003] The "building machine" facade is divided into functional zones from bottom to top as follows: subsequent operation layer, support climbing layer, concrete curing layer, formwork operation layer, rebar operation layer, steel platform layer, and top load layer, thus forming a three-dimensional cross-operation system. Compared with traditional construction formwork, this reduces safety risks, improves the working environment, enables all-weather construction operations, and greatly improves construction efficiency.

[0004] In the design and application of the lifting and support system of the previous "building machine", the overall weight of the support system has always been one of the major obstacles to achieving the goal of lightweighting the "building machine". Solving the weight problem of the support system, safety, speed and intelligence are the directions of research and development and industrial application. During the lifting process, it is necessary for a dedicated person to monitor each column one by one to check whether the hook at the support point position has entered the ladder rung and is under normal force in real time. If human error occurs, the lifting time is limited. In some special scenarios, the safety of personnel cannot be guaranteed, and it is not convenient for occasional night work. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an integrated support and lifting device that can ensure rapid and safe lifting throughout the entire process, and can promptly verify the stress state of the hooks entering the ladder rungs.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An integrated support and lifting device is constructed, including a support column, a bracket, a hook, a spreader pole, a one-way self-locking clamp, a climbing pole, a crossbeam, a hydraulic cylinder, and a hook detection sensor; the top of the support column is fixedly connected to the lower chord of the Bailey bridge frame of the building machine; the bracket is connected to the main structure; the hook is connected to the bracket via a pin; the hook supports the support column via the ladder rungs of the support column; the spreader pole is connected to the bracket via a pin; and a one-way self-locking clamp is installed on the spreader pole. The self-locking clamp, when tightened, holds the upper part of the climbing rod, restricting its movement upwards during lifting. The lower part of the climbing rod is connected to a crossbeam built into the cavity of the support column via a pin. The lower part of the crossbeam is connected to the lower part of a hydraulic cylinder built into the cavity of the support column. The upper part of the hydraulic cylinder is connected to the support column, and the bottom of the hydraulic cylinder is connected to the crossbeam via a pin. The claw detection sensor is built into the cavity of the support column, and during the lifting process, the distance between the claw and the sensor is detected in real time.

[0007] In the above scheme, the supporting column is connected to the lower chord of the Bailey bridge of the building machine by bolts.

[0008] In the above scheme, the mounting bracket is connected to the main structure by bolts.

[0009] In the above scheme, the support column is provided with a vertical sealing plate, which provides a step for supporting the hook claw.

[0010] In the above scheme, the climbing pole is made of solid round steel.

[0011] In the above scheme, multiple hydraulic cylinders are dynamically adjusted and monitored synchronously through oil pressure and real-time displacement to achieve synchronous extension of multiple cylinders, thereby enabling multiple support columns to rise synchronously.

[0012] In the above scheme, the claw detection sensor is a photoelectric claw detection sensor.

[0013] In the above scheme, the hook detection sensor is installed on the sensor bracket. The top of the sensor bracket can move when the hook enters or does not enter the ladder step. The bracket track remains vertical, and the steel plate on the track remains vertical, ensuring that the hook detection sensor can detect vertical distance at any time.

[0014] The above scheme also includes adjusting the fall arrestor and the fall arrestor base, and adjusting the fall arrestor and the fall arrestor base to fit into the reserved hole of the hanging seat.

[0015] The integrated support and lifting device of this utility model has the following beneficial effects:

[0016] 1. This utility model uses a hook detection sensor installed inside the support column to monitor and provide feedback on the stroke of the hydraulic cylinder and the hook's support column movement, ensuring the reliable implementation of each link and thus guaranteeing a fast, continuous, and safe lifting process.

[0017] 2. This utility model is a novel structure for a lifting and support system. The hydraulic cylinder is equipped with a displacement hook detection sensor to determine and provide feedback on the cylinder's extension length and whether it has entered the ladder rung and is under normal force, thereby controlling and realizing the automatic lifting of the cylinder under the control of the electronic control system. The integrated hook detection sensor can ensure the safety, speed, continuity and reliability of the lifting process, and can realize unattended support points during the lifting process, further reducing the manufacturing cost of the "building machine" and the manual input in the operation and maintenance process, and further improving the level of intelligence.

[0018] 3. This utility model allows for the specification of the rated bearing capacity of the support column, designed as a 50t rated lifting capacity type, which promotes production standardization; it changes the force transmission and safety mechanism of the original support system, expands the application range of the support column for the height of civil engineering structures, and makes the lifting process faster, safer, and more reliable.

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 7 As shown, the integrated support and lifting device of this utility model includes a support column 1, high-strength bolts 2, structural wall 3, through-wall high-strength bolts 4, hanging seat 5, one-way self-locking clamp 6, spreading pole 7, hook claw 8, climbing pole 9, hook claw detection sensor signal transmitting device 10, hydraulic cylinder 11, crossbeam 12, internal stiffening plate of column 13, ladder rung 14, hook claw detection sensor 15, sensor bracket 16, adjustable fall arrestor 17, and adjustable fall arrestor base 18.

[0029] like Figure 1 As shown, during the lifting of the "building machine," it is supported by three sets of brackets 5. The middle bracket serves as the main load-bearing component for vertical forces, while the upper and lower brackets 5 primarily bear horizontal forces to prevent the column from tilting. The brackets 5 are connected to the main structural wall 3 via through-wall high-strength bolts 4. The hooks 8 are combined with the brackets 5 via pins, and the hooks 8 support the column through the ladder runners 14 provided by the column's own structure. The spreader 7 is connected to the brackets 5 via pins. A one-way self-locking clamp 6 is installed on the spreader 7 to clamp the upper part of the climbing rod 9 and restrict the climbing rod to only move upwards. The lower part of the climbing rod 9 is connected to the support built into the support. The crossbeam 12 inside the support column cavity is connected by a pin. The lower part of the crossbeam 12 is connected to the lower part of the hydraulic cylinder 11 built into the support column cavity. The upper part of the hydraulic cylinder 11 is connected to the stiffening plate 13 inside the support column. During the lifting process, the hook detection sensor signal transmitter 10 starts to work continuously to detect the distance between the hook and the transmitter. Based on this, it is determined whether the hook 8 has entered the step 14 and is approaching the last stroke of the non-standard layer. The sensor base 18 is adjusted and placed into the reserved hole of the hanger 5. As the cylinder retracts, the sensor 17 is adjusted to lock the hook 8, and the lifting is completed.

[0030] The working principle of this utility model is as follows:

[0031] By extending the hydraulic cylinder 11, the support column 1 is pushed upward, and the support column 1 disengages from the hook 8. At this time, the crossbeam 12 transmits the downward force it receives to the climbing pole 9, then to the spreader 7 and the hanging seat 5, and finally to the main structural wall 3. After the hydraulic cylinder 11 drives the support column 1 to rise by one stroke, the hook 8 supports the support column 1 again. By retracting the hydraulic cylinder 11, the climbing pole 9 and the crossbeam 12 rise by one stroke. Finally, the one-way self-locking head 6 of the spreader 7 locks the climbing pole 9 again. By repeating the above steps, the support column 1 is lifted to the predetermined total height through multiple small strokes of the hydraulic cylinder 11. During the process, the signal transmission 10 of the hook detection sensor installed in the support column 1 is used to monitor and provide feedback on the stroke of the hydraulic cylinder 11 and the action of the hook 8 supporting the support column 1. When the program-set distance is reached, the force state of the hook 8 entering the step 14 is detected. In the last stroke, the use of the fall arrestor 17 and the base 18 is adjusted so that the support system can be used in non-standard floor lifting environments without restriction, ensuring the reliable implementation of each link.

[0032] like Figure 1 and Figure 5 As shown, the hydraulic cylinder 11 is equipped with a displacement hook detection sensor 15 and a matching power pump station 16. The displacement hook detection sensor 15 is used to determine and provide feedback on the extension length of the cylinder, and the power pump station 16 is used to provide power for the extension of the hydraulic cylinder 11, so as to realize the automatic lifting of the cylinder under the control of the electronic control system.

[0033] The lifting and support system of this utility model raises the steel platform, thus lifting the "building machine". This utility model can be widely used in the construction of lifting formwork and similar lifting or supporting structures, and is also within the protection scope of the claims of this utility model.

[0034] In the above embodiment, the supporting column 1 includes high-strength bolts 2, structural steel, vertical sealing plates, horizontal stiffening plates, steel plates, and connecting bolts. The high-strength bolts 2 can move horizontally within a certain range relative to the center of the column. A single supporting column 1 has a bearing capacity of 50t. The vertical sealing plates can provide step supports for the hook 8, and the internal cavity can provide sufficient protection for the hydraulic cylinder 11 and the hook detection sensor 10.

[0035] In the above embodiment, the hook 8 is made of steel plate. When the support column 1 rises, the hook 8 can rotate by the upward friction of the support column 1, so as not to hinder the rise of the support column 1. However, when the support column 1 falls, it encounters the step 14, and the hook 8 will automatically rotate under its own weight and support the step 14 of the support column 1.

[0036] In the above embodiment, a one-way self-locking clamp 6 is installed on the spreading pole 7. The self-locking clamp 6 can clamp the upper part of the climbing pole 9, which is sufficient to counteract the vertical downward pull during the upward process of the supporting column 1, thereby restricting the climbing pole 9 to only go upward, and also serving as a fall arrestor.

[0037] In the above embodiment, the climbing pole 9 is made of solid 45# round steel, which can support the vertical force on the entire support column 1 and is more conducive to the verticality control of the support column 1 during the rising process. It rises with the retraction of the hydraulic cylinder 11.

[0038] In the above embodiment, the hydraulic cylinder 11 is a cavity built into the support column 1. A bidirectional hydraulic pump is driven by a speed-regulating motor, which directly drives the hydraulic cylinder to extend, thereby pushing the support column 1 upward. Multiple hydraulic cylinders 11 are dynamically adjusted and monitored synchronously through oil pressure and real-time displacement, so as to realize the synchronous extension of multiple cylinders 11 and thus the synchronous rising of multiple support columns 1.

[0039] In the above embodiment, the hook detection sensor 10 is installed in a cavity inside the support column 1, and is tightly connected to each hook step 14 of the support column 1. A photoelectric hook detection sensor transmitting device 10 is used. The hook detection sensor signal transmitting device 10 can detect the rebound signal, thereby detecting the distance from the hook 8 to the device, and determining whether the hook 8 has entered the step 14 and entered the normal force state during the lifting process. This realizes the monitoring of the hook 8's movement and feedback of the force state. Compared with the previous method of manually observing each column, especially in low light conditions, this method has significant advantages and speeds up the lifting speed while ensuring safety and reliability.

[0040] In the above embodiments, since the column support system is a fully functional and relatively complex structural design, it is mainly suitable for the most common residential floor height of 3 meters. The same effect can also be achieved in non-standard floor conditions. Through multiple small strokes (300mm) of the hydraulic cylinder, when encountering floor heights that are not multiples of 300mm, after all 300mm strokes are completed normally, the last stroke pre-lifts by 50mm to maintain hydraulic pressure. The anti-fall device 17 and its base 18 are then installed, and the hydraulic cylinder is retracted, achieving the same force state as when the hook enters the ladder rung 14, thus enabling the support column to complete the lifting of the predetermined total height of the non-standard floor. The embodiments of this utility model have been described above with reference to the accompanying drawings. However, this utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this utility model, can make many other forms without departing from the spirit and scope of the claims, and these all fall within the protection scope of this utility model.
