Description

Technical Field

[0001] This utility model relates to the field of bored pile construction technology, specifically to a multi-functional well frame for manual bored pile construction. Background Technology

[0002] In the construction of manually excavated bored piles, the derrick is a crucial piece of equipment used for lifting and transporting excavated soil, building materials, and personnel. Traditional manually excavated bored pile derricks have several problems: 1. The standards for steel pipe derrick erection are not uniform, and the erection of steel pipe derricks is highly arbitrary. The height and style are inconsistent in each project, making on-site inspection and acceptance difficult.

[0003] 2. Some derricks are made of square steel and columns, which are inconvenient to install and dismantle, and do not have the conditions for installing wire ropes, grounding devices, guardrails, etc. They need to be temporarily installed on site later, which can easily lead to inconsistencies between safety measures and derrick support.

[0004] 3. Poor installation, dismantling, and reusability: Many well structure components are welded together, resulting in low reusability.

[0005] 4. Overly high derrick height: When operating near railways, the overturning distance of the derrick needs to be considered. Therefore, using a low headroom derrick is the preferred option. Currently, the height of derricks on the market is generally too high. This does not take into account the situation where the height of the derrick should be appropriately reduced when the proximity to railways is not taken into account.

[0006] Based on the above problems, it is of great practical significance to develop a manually excavated pile shaft frame that is detachable, easy to transport, and highly versatile. Summary of the Invention

[0007] The purpose of this utility model is to address the shortcomings of the prior art by providing a multi-functional derrick for manually excavated pile construction. This multi-functional derrick allows for easy removal of materials and equipment from the well by setting a top cantilever track on the top of the cubic derrick, eliminating the need to increase the hoisting height by increasing the height of the derrick. Furthermore, the use of bolted connections enables rapid installation and dismantling of the cubic derrick.

[0008] The objective of this utility model is achieved through the following technical solution: A multi-functional derrick for manually excavated pile foundation construction is characterized in that: the multi-functional derrick includes a derrick foundation ring, a cubic derrick, a grounding connection device, and a top cantilever track; the derrick foundation ring is anchored to the ground via the grounding connection device; the cubic derrick is vertically fixed to the derrick foundation ring; a portion of the length of the top cantilever track is fixed to the top of the cubic derrick, and the remaining portion cantilevers outward from the top of the cubic derrick; a sliding pulley is installed on the top cantilever track, and the sliding pulley has a locking mechanism to fix it on the top cantilever track to maintain a fixed position; and a winch mechanism is also installed at the bottom of the cubic derrick, with one end of the winch mechanism's steel cable wound around the winch mechanism's shaft, and the other end wound around the sliding pulley and used to hoist objects.

[0009] The cubic derrick includes four square steel uprights and four horizontal top rods. The bottom of each square steel upright is fixed with a column base plate having an area larger than the horizontal cross-sectional area of ​​the upright. Bolt holes are made in the column base plate, and expansion bolts are driven into the derrick foundation ring to fix the square steel upright to the derrick foundation ring. The top of each square steel upright is fixed with a column top plate having an area larger than the horizontal cross-sectional area of ​​the upright. The four horizontal top rods are arranged in pairs, stacked vertically. In one pair, the two horizontal top rods are arranged longitudinally and parallel to each other, while in the other pair, the two horizontal top rods are arranged laterally and parallel to each other. The ends of the two lower horizontal top rods are bolted to the column top plate of the square steel upright.

[0010] The cubic derrick also includes reinforcing angle irons and scissor braces. The reinforcing angle irons are installed between the horizontal top rod and the square steel upright, and the scissor braces are installed between adjacent square steel uprights.

[0011] Each of the square steel uprights is welded with a hook in the middle, and horizontal steel wire ropes are provided on the three sides of the cubic derrick, with the two ends of the horizontal steel wire ropes being fixedly connected to the hooks respectively.

[0012] The grounding connection device is a "∩" shaped steel bar. The grounding connection device is fastened to the well ring of the well frame foundation, and the vertical steel bars on both sides are inserted into the soil for anchoring.

[0013] The top cantilevered track is made of I-beams. Several limiting holes are spaced longitudinally on the web of the top cantilevered track. A rotating arc rod is provided on the wheel frame of the slidable pulley to control the rotating arc rod to flip and insert into the limiting hole to restrict the longitudinal movement of the slidable pulley.

[0014] The advantages of this utility model are: (1) The cantilevered track at the top of the cubic derrick extends out of the derrick, which allows the materials and equipment hoisted out of the well to be easily moved out of the well without increasing the hoisting height by increasing the height of the cubic derrick to pull the hoisted object out of the well. (2) By setting hooks and horizontal steel wire ropes on the square steel uprights, the safety rope hooks of the construction workers can be fastened on them and slide freely; (3) The cubic derrick is connected by connecting plates and bolts, which allows ordinary workers to complete the installation and dismantling of the derrick in a short time, thus improving construction efficiency.

Detailed Implementation

[0016] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art: Example: Figure 1 , 2As shown in Figure 3, this embodiment specifically relates to a multi-functional derrick for manual excavation of bored piles. The multi-functional derrick includes a derrick foundation ring 4, a cubic derrick, a grounding connection device 5, and a top cantilever track 3. The derrick foundation ring 4 is anchored to the ground through the grounding connection device 5. The cubic derrick is vertically fixed to the derrick foundation ring 4. A portion of the length of the top cantilever track 3 is fixed to the top of the cubic derrick, and the remaining portion cantilevered outward from the top of the cubic derrick. A sliding pulley 14 is installed on the top cantilever track 3. The sliding pulley 14 has a locking mechanism to fix it to the top cantilever track 3 to maintain a fixed position. Furthermore, a winch mechanism (not shown in the figure) is installed at the bottom of the cubic derrick. The winch mechanism is fixed by a motor mounting steel pipe frame 12 at the bottom of the cubic derrick. One end of the steel cable of the winch mechanism is wound around the shaft of the winch mechanism, and the other end is wound around the sliding pulley 14 and used to hoist objects.

[0017] like Figure 1 , 2 As shown in Figure 3, the derrick foundation well ring 4 is a precast concrete component with a certain thickness to serve as the support platform for the cubic derrick. The derrick foundation well ring 4 has a rectangular structure with a central circular hole for communication with the inside of the well. The connection between the derrick foundation well ring 4 and the construction ground is achieved by a grounding connection device 5, which is a "∩" shaped steel bar. The grounding connection device 5 is fastened to the derrick foundation well ring 4, and the vertical steel bars on both sides are inserted into the soil for anchoring. In this way, the stability of the derrick foundation well ring 4 and the cubic derrick installed on it can be ensured by the self-weight of the derrick foundation well ring 4 and the anchoring of the grounding connection device 5.

[0018] like Figure 1 , 2As shown in Figure 3, the cubic derrick includes four square steel uprights 1 and four horizontal top rods 2. The bottom of the square steel uprights 1 is fixed with a column base steel plate 7 with an area larger than the horizontal cross-sectional area of ​​the square steel uprights 1. The column base steel plate 7 is fixed to the derrick foundation well ring 4 by opening bolt holes and driving expansion bolts 8 into the well ring 4 of the derrick foundation. The top of the square steel uprights 1 is fixed with a column top steel plate with an area larger than the horizontal cross-sectional area of ​​the square steel uprights 1. The four horizontal top rods 2 are arranged in pairs, stacked on top of each other. The two horizontal top rods 2 in one pair are arranged longitudinally and parallel to each other, and the two horizontal top rods 2 in the other pair are arranged laterally and parallel to each other. The ends of the two horizontal top rods 2 located at the bottom are fixed to the column top steel plate of the square steel uprights 1 with bolts. In addition, the cubic derrick also includes reinforcing angle irons 13 and scissor braces 11. The reinforcing angle irons 13 are installed between the horizontal top rod 2 and the square steel upright 1, and the scissor braces 11 are installed between adjacent square steel uprights 1. The installation of reinforcing angle irons 13 and scissor braces 11 improves the structural stability of the cubic derrick. Guardrails 6 are installed on the three lower sides of the cubic derrick as safety barriers.

[0019] like Figure 1 , 2 As shown in Figure 3, hooks 9 are welded to the middle of each of the steel uprights 1, and horizontal steel wire ropes 11 are installed on the three sides of the cubic derrick. The two ends of the horizontal steel wire ropes 11 are fixedly connected to the hooks 9. The installation of the horizontal steel wire ropes 11 allows the safety rope hooks of the construction personnel to be fastened to them and slide freely.

[0020] like Figure 4 , 5 As shown, each top cantilevered track 3 is made of I-beams. Several limiting holes 15 are longitudinally spaced on the web of the top cantilevered track 3. A traveling wheel is installed on the upper part of the wheel frame of the sliding pulley 14 to allow it to roll on the top cantilevered track 3. Additionally, a fixed pulley is installed at the lower part of the wheel frame of the sliding pulley 14. This fixed pulley is used to wind the steel cable of the winch mechanism for hoisting. A rotating arc-shaped rod 16 is provided at the top of the wheel frame. By rotating the arc-shaped rod 16, its insertion into the limiting hole 15 can be controlled, thus achieving longitudinal positioning of the sliding pulley 14. The rotation of the rotating arc-shaped rod 16 is driven by a small motor.

[0021] The beneficial effects of this embodiment are: (1) The cantilevered track at the top of the cubic derrick extends out of the derrick, which allows the materials and equipment hoisted out of the well to be easily moved out of the well without increasing the hoisting height by increasing the height of the cubic derrick to pull the hoisted object out of the well. (2) By setting hooks and horizontal steel wire ropes on the square steel uprights, the safety rope hooks of the construction workers can be fastened on them and slide freely; (3) The cubic derrick is connected by connecting plates and bolts, which allows ordinary workers to complete the installation and dismantling of the derrick in a short time, thus improving construction efficiency.
