Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a device for hoisting engineering piles. Background Technology

[0002] With the development of the construction industry and the advancement of building industrialization, construction technology is constantly improving. Some building components, including micropiles, are gradually replacing the traditional on-site casting method with prefabricated steel reinforcement components. Taking micropiles as an example, the prefabricated steel reinforcement component method involves prefabricating steel cages or steel meshes into micropiles outside the construction site, then transporting the micropiles to the construction site, and using hoisting machines and hoisting devices to lift the micropiles to the installation position and fix them to the building structure.

[0003] Existing hoisting equipment includes a hoisting frame that serves as the machine frame and a locking structure for securing the component to be hoisted to the hoisting frame. To ensure the reliability of the locking mechanism between the component and the hoisting frame, multiple sets of locking structures are typically required circumferentially. While existing hoisting equipment can basically meet the hoisting requirements of micropiles, some problems still exist. For example, the locking structure is purely mechanical, requiring workers to adjust each locking structure individually before each hoisting of a micropile, which is cumbersome and inefficient. Furthermore, adjusting the locking structure requires workers to be close to it, posing a safety hazard such as the micropiles tipping over and injuring workers. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] A type of engineering pile hoisting device, such as Figures 1-3 As shown, its structural relationship is as follows: it includes a hoisting frame 4, which is hoisted by a hoisting machine. The hoisting frame 4 is equipped with a locking structure 2 for limiting and locking the engineering pile to the hoisting frame 4. The hoisting frame 4 has a cavity 41 for accommodating the engineering pile 3 inside, and the bottom is an opening for the engineering pile 3 to enter the cavity 41. At least one pair of locking structures 2 are fixed to the bottom outer side of the lifting frame 4 in a circumferentially evenly distributed manner; The locking structure 2 includes a housing 21, a support block 22, and a drive structure; the support block 22 is slidably inserted into a groove 23 opened in the housing 21; the drive structure can output the movement of driving the support block 22 to slide out from the inside of the housing 21 towards the opening below and / or driving the support block 22 to slide back from the opening below into the housing 21. It also includes a base 1, the top of which has a clearance notch 11 corresponding to the locking structure 2; and an engineering pile 3 placed on top of the base 1.

[0022] Furthermore, the drive structure can output the movement of the drive block 22 sliding out from inside the housing 21 towards the opening below or the drive block 22 sliding back into the housing 21 from the opening below. The locking structure 2 also includes a mounting groove 24, a guide rod 25, a slider 26, and a spring 27; The outer casing 21 has an installation groove 24 that communicates with the slide groove 23. The guide rod 25 is installed and fixed in the installation groove 24. The slider 26 is fixedly connected to the support block 22 and is slidably installed on the guide rod 25. A sliding pair is formed between the slider 26 and the guide rod 25 to support the slider 26 to slide synchronously with the support block 22. Spring 27 is sleeved on guide rod 25, and its two ends are respectively connected and fixed to the end face of slider 26 and mounting groove 24. When the drive structure can output the movement of driving block 22 to slide out from inside the housing 21 to the bottom of the opening, the elastic force of spring 27 tends to make block 22 slide back into the housing 21. Or when the drive structure can output the movement of driving block 22 to slide back from the bottom of the opening to the inside of the housing 21, the elastic force of spring 27 tends to make block 22 slide out from the housing 21.

[0023] Furthermore, the drive structure can output the motion of the drive block 22 sliding and retracting from the opening downwards into the housing 21; Spring 27 is a tension spring, located between the inner end of mounting groove 24 and slider 26.

[0024] Furthermore, the driving structure includes an electromagnet 28 equipped with a power supply and an iron block 29; Either electromagnet 28 or iron block 29 is installed and fixed to the outer end of support block 22, and the other is installed and fixed to the outer end of slide groove 23.

[0025] Furthermore, the electromagnet 28 and the iron block 29 are respectively installed and fixed to the outer end of the slide 23 and the outer end of the support block 22, and the outer end of the slide 23 is provided with a wire hole for wiring the power supply magnet 28.

[0026] Furthermore, four locking structures 2 are evenly distributed around the bottom outer side of the hoisting frame 4, and four notches 11 are evenly distributed around the base 1.

[0027] Furthermore, it also includes box 5, infrared receiver module, controller, wireless remote control and battery; The box 5 is installed and fixed to the outside of the hoisting frame 4, and a wire hole for wiring is opened on it. An infrared receiving module and a storage battery are installed and fixed inside it. The battery is electrically connected to the electromagnet 28, and the wireless remote control and infrared receiving module are data connected. The signal output terminal of the infrared receiving module is connected to the signal input terminal of the controller, and the signal output terminal of the controller is connected to the signal input terminal of the electromagnet 28.

[0028] The preferred model for the infrared receiver module is HS0038, and the preferred model for the controller is ESP8266.

[0029] Furthermore, the front of the box body 5 is provided with an opening, and a protective net is installed over the opening.

[0030] Furthermore, an ear plate 12 for fixing the base 1 is fixed on the outer side of the bottom. The ear plate 12 has a mounting hole. Construction workers can install and fix the base 1 on the construction site by pressing a heavy object such as a stone on the ear plate 12 or by using a connector at the mounting hole.

[0031] Furthermore, four lifting rings 42 are evenly distributed around the top circumference of the lifting frame 4, and the lifting frame 4 is connected to the lifting machine through each lifting ring 42.

[0032] The process of hoisting and installing engineering piles using the aforementioned engineering pile hoisting device includes the following steps: The first step is to transport the engineering pile 3 to the hoisting device using a transport device, so that the engineering pile 3 is placed upright on top of the base 1.

[0033] The second step is for the hoisting machine to hoist the hoisting device above the engineering pile 3, so that the opening of the hoisting frame 4 is directly facing the engineering pile 3; Subsequently, the construction workers used a wireless remote control to energize the electromagnet 28, causing a magnetic attraction between the electromagnet 28 and the iron block 29. In each locking structure 2, the support block 22, under the magnetic attraction between the iron block 29 and the electromagnet 28, overcomes the elastic force of the spring 27 and slides back into the outer shell 21, so that the opening at the bottom of the hoisting frame 4 is fully exposed.

[0034] The third step is to lower the hoisting device with the hoisting machine so that the engineering pile 3 enters the cavity 41 of the hoisting frame 4 through the opening at the bottom of the hoisting frame 4 until the hoisting frame 4 completely covers the engineering pile 3. At this time, each locking structure 2 is precisely embedded into each notch 11 in a corresponding manner, with a height lower than the bottom height of the engineering pile 3.

[0035] Fourth step: The construction workers control the electromagnet 28 to turn off the power, and the magnetic attraction between the electromagnet 28 and the iron block 29 disappears; In each locking structure 2, the support block 22 slides out of the outer shell 21 under the action of the spring 27 and extends to the bottom of the opening, confining the engineering pile 3 in the cavity 41, thereby realizing the limiting and locking between the hoisting frame 4 and the engineering pile 3.

[0036] The fifth step is to use the hoisting device to lift the engineering pile 3 to the installation position and fix it to the building structure.
