Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a steel pipe pile construction device. Background Art

[0002] During the construction of bridges, it is common to use Bailey frames to build steel trestles. Mechanical equipment lifts steel pipe piles on the steel trestles and places them vertically into the river, and then uses a vibrating hammer to sink the steel pipe piles into the geology. In the process of sinking the steel pipe piles into the geology, in order to ensure the quality of bridge construction and make the bridge have good stability and load-bearing capacity, the steel pipe piles must meet the verticality required by the design when they are sunk into the geology. At present, construction personnel use a combination of Bailey frames and I-beams to control the verticality of steel pipe piles. The Bailey beam includes an upper main beam and a lower main beam. The upper and lower main beams each include two main beams. The four main beams form a square structure under the connection of the support bars. Two I-beams are connected to the upper main beam in a length direction perpendicular to the upper main beam. The upper main beam forms a well shape. Then the steel pipe piles are lifted and passed through the middle position of the well structure, thereby achieving the control of the verticality of the steel pipe piles when the steel pipe piles slowly sink into the geological layer. However, in actual construction, the distance between the two main beams of the upper main beam is much larger than the outer diameter of the steel pipe piles. Therefore, the steel pipe piles still have a large space for movement in this tic-tac-toe structure, making it difficult to ensure the verticality of the steel pipe piles. In summary, the existing technology has the problem that the verticality of the steel pipe piles is difficult to control. Utility Model Content

[0003] The utility model aims to provide a steel pipe pile construction device to solve the problem that the verticality of the steel pipe pile is difficult to control in the prior art.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a steel pipe pile construction device, including a Bailey frame, a fixing unit is detachably connected to the upper main beam of the Bailey frame, a guide member is connected to the fixing unit, a guide hole is provided in the guide member for vertical movement of the steel pipe pile, and the inner diameter of the guide hole is 1-2 mm larger than the outer diameter of the steel pipe pile.

[0005] The principle and effect of this scheme are as follows: in actual application, mechanical equipment lifts the steel pipe pile and places the steel pipe pile into the guide member. Here, the guide member firstly guides the steel pipe pile so that the steel pipe pile can quickly find the position where it needs to be placed, and secondly guides the movement of the steel pipe pile in the vertical direction. Specifically, the guide hole on the guide member is only 1-2mm larger than the steel pipe pile. It can guide and limit the steel pipe pile in the vertical direction of the steel pipe pile to control the verticality of the steel pipe pile.

[0006] Preferably, as an improvement, the guide member is provided with a chamfer at the upper end of the guide hole for allowing the steel pipe pile to enter the guide hole.

[0007] In this solution, this design can facilitate the steel pipe pile to enter the guide hole more quickly.

[0008] Preferably, as an improvement, at least three limiting protrusions are provided on the hole wall of the guide member along the length direction of the guide member, all the limiting protrusions are evenly distributed along the circumference of the hole wall, and the inner diameter of the guide hole is the diameter of the inscribed circle surrounded by all the limiting protrusions.

[0009] In this solution, this design can transform the friction between the steel pipe pile and the guide member hole wall into the friction between the steel pipe pile and the limiting convex. Since the limiting convex has a certain length in the length direction of the guide member, the surface friction is transformed into line friction, which significantly reduces the friction between the steel pipe pile and the guide member, and is conducive to the smooth passage of the steel pipe pile through the guide member.

[0010] Preferably, as an improvement, the guide member comprises a sleeve.

[0011] The sleeve of this solution has a simple structure and is easy to process.

[0012] Preferably, as an improvement, the guide member is fixedly connected to the fixing unit, the bottom end of the guide member is fixedly connected to a limiting mechanism, and the limiting mechanism is in contact with the inner wall of the lower main beam of the Bailey frame at the same time.

[0013] In this solution, a limiting mechanism is provided at the bottom end of the guide member to limit the position of the bottom end of the guide member, thereby preventing the bottom end of the guide member from being deflected and affecting the verticality of the steel pipe pile.

[0014] Preferably, as an improvement, the bottom end of the limiting mechanism is provided with a guiding inclined surface matching with the lower main beam.

[0015] In this solution, a guiding slope is provided at the bottom end of the limiting mechanism so that the limiting mechanism can be placed in the lower main beam more conveniently and quickly.

[0016] Preferably, as an improvement, the fixed unit includes a first movable frame and a second movable frame, the first movable frame is slidably connected to the upper main beam along the length direction of the upper main beam; the second movable frame is slidably connected to the first movable frame along the length direction perpendicular to the upper main beam, and the guide member is fixedly connected to the second movable frame.

[0017] In the present solution, this design allows construction workers to flexibly adjust the position of the guide member, thereby making the device more practical.

[0018] Preferably, as an improvement, a first waist-shaped hole is provided on the first movable frame along the length direction of the upper main beam, and a threaded hole matching the first waist-shaped hole is provided on the upper main beam.

[0019] Preferably, as an improvement, a second waist-shaped hole is provided on the second movable frame along a direction perpendicular to the length of the upper main beam, and a threaded hole matching the second waist-shaped hole is provided on the first movable frame.

[0020] The above two designs show the fixing and sliding methods of the first movable frame and the upper main beam, and the second movable frame and the first movable frame, which is relatively simple in terms of operations such as processing, installation and adjustment of the position of the guide parts.

DETAILED DESCRIPTION

[0027] The following is further described in detail through specific implementation methods:

[0028] Example 1

[0029] Basically as attached Figure 1 As shown: a steel pipe pile construction device, including a Bailey frame, the upper main beam 11 of the Bailey frame is detachably connected with a fixing unit 2. Compared with a non-detachable connection such as welding, the detachable connection allows the construction personnel to remove the fixing unit 2 after the steel pipe pile is lowered, and then lay a flat plate on the Bailey frame here, which is convenient for the mechanical equipment to continue to move forward for construction. The fixing unit 2 is removed to avoid possible interference between the fixing unit 2 and the flat plate. At the same time, the construction personnel can use the removed fixing unit 2 to reinstall and utilize it in the next required place. Here, the detachable connection method can be various methods such as threaded connection, pin connection, bayonet connection, nut connection, etc.

[0030] The fixing unit 2 is connected with a guide member 3, and a guide hole 4 is provided inside the guide member 3 for the vertical movement of the steel pipe pile 7, and the inner diameter of the guide hole 4 is 1-2 mm larger than the outer diameter of the steel pipe pile 7. The inner diameter of the guide hole 4 is designed to be 1-2 mm larger than the outer diameter of the steel pipe pile 7, so as to limit the displacement range of the steel pipe pile 7 in the guide hole 4, thereby effectively controlling the verticality of the steel pipe pile 7. In addition, the structure of the guide member 3 can be various, as long as the guide hole 4 thereon can play a guiding and limiting role for the steel pipe pile 7. As one embodiment, the guide member 3 includes a sleeve, and the inner circle on the sleeve is the guide hole 4.

[0031] As for the length of the guide member 3 in the vertical direction, as an example, the length of the guide member 3 in the vertical direction is designed to be greater than or equal to 300 mm. Figure 3 As shown, the guide member 3 provides a relatively long limit guide for the steel pipe pile 7 in the vertical direction, so that the steel pipe pile 7 can achieve a better verticality.

[0032] In actual application, the steel pipe pile 7 is lifted and then gradually sinks into the water through the guide hole 4. Here, it can be understood that since the inner diameter of the guide hole 4 is only 1-2 mm larger than the outer diameter of the steel pipe pile 7, the steel pipe pile 7 often rubs against the hole wall in the guide hole 4, thereby affecting the descending process of the steel pipe pile 7. For this reason, as a further improvement, at least three limiting protrusions 6 are arranged on the hole wall of the guide member 3 along the length direction of the guide member 3, and all the limiting protrusions 6 are evenly distributed along the circumference of the hole wall. At this time, the inner diameter of the guide hole is the diameter of the inscribed circle surrounded by all the limiting protrusions. Therefore, the limiting protrusion 6 plays a role of limiting and guiding the steel pipe pile 7 here, and at the same time, the friction between the steel pipe pile 7 and the hole wall of the guide member 3 will be changed into the friction between the steel pipe pile 7 and the limiting protrusion 6, that is, the friction between the surface is changed into the friction between the line, thereby reducing the friction force in the descending process of the steel pipe pile 7, which is conducive to the steel pipe pile 7 to pass through the guide hole 4 quickly and smoothly. In order to make the limiting protrusion 6 provide a relatively long limiting guide for the steel pipe pile 7 so that the steel pipe pile 7 can achieve better verticality, as an example, the limiting protrusion 6 is designed to be greater than or equal to 300 mm in the length direction of the guide member 3 and less than or equal to the length of the guide hole 4.

[0033] As can be seen from the above, the offset space of the steel pipe pile 7 in the guide hole 4 is small. It is a bit difficult to put the steel pipe pile 7 into the guide hole 4 after it is lifted, and it is not easy to align. Therefore, as a further improvement, the guide member 3 is provided with a chamfer at the upper end of the guide hole 4 to facilitate the steel pipe pile 7 to enter the guide hole 4.

[0034] The fixing unit 2 is connected with a guide member 3, and the connection between the two can be various. As an example, the guide member 3 is welded to the fixing unit 2. It can be understood that the position of the bottom end of the guide member 3 should also be fixed, but in actual applications, due to installation or vibration, the bottom end of the guide member 3 may be deflected, thereby affecting the verticality of the steel pipe pile 7. As a further improvement, a limiting mechanism 5 is provided at the bottom end of the guide member 3. The two can be welded or detachably connected. The limiting mechanism 5 is also in contact with the inner wall of the lower main beam 12 of the Bailey frame. Here, for the convenience of understanding, as an example, the limiting mechanism is designed to be a square structure, such as Figure 2 This solution limits the bottom end of the guide member 3 by limiting the limiting mechanism 5 between the two main beams of the lower main beam 12 to prevent it from deflecting, thereby effectively ensuring the verticality of the steel pipe pile 7.

[0035] In the above scheme, since the limiting mechanism 5 is in contact with the inner wall of the lower main beam 12 of the Bailey frame, that is, the width of the limiting mechanism 5 is equal to the spacing between the two main beams of the lower main beam 12, it is difficult to put the limiting mechanism 5 between the two main beams of the lower main beam 12. As a further improvement, a guiding inclined surface matching the lower main beam 12 is provided at the bottom end of the limiting mechanism 5, such as Figure 2 As shown, when the limiting mechanism 5 is placed, the guiding slope can guide the limiting mechanism 5 to enter between the two main beams of the lower main beam 12.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 lies in the difference of the fixing unit 2. Figure 4 and Figure 5 As shown, the fixed unit 2 includes a first movable frame 21 and a second movable frame 22. The first movable frame 21 is slidably connected to the upper main beam 11 along the length direction of the upper main beam 11. This design allows the first movable frame 21 to be adjusted in the length direction of the upper main beam 11; the second movable frame 22 is slidably connected to the first movable frame 21 along a direction perpendicular to the length of the upper main beam 11, and the guide member 3 is fixedly connected to the second movable frame 22. This design allows the second movable frame 22 and the guide member 3 to be adjusted in the length direction perpendicular to the upper main beam 11. Through the adjustments in the above two directions, the position of the guide member 3 can be changed to adapt to different sinking positions of the steel pipe piles 7.

[0038] The sliding connection can be designed by a person skilled in the art in various sliding connection methods. As an example, the sliding connection between the first movable frame 21 and the Bailey frame is as follows: Figure 4As shown, the first movable frame 21 is provided with a first waist-shaped hole 23 along the length direction of the upper main beam 11, and the upper main beam 11 is provided with a threaded hole that matches the first waist-shaped hole 23. In actual application, the position of the first movable frame 21 is first adjusted. After the position is determined, a stud is passed through the first waist-shaped hole 23 and the threaded hole of the upper main beam 11, so that the first movable frame 21 is connected and fixed to the upper main beam 11. As for the sliding connection between the first movable frame 21 and the second movable frame 22, as an example, Figure 4 As shown, the second movable frame 22 is provided with a second waist-shaped hole 24 along the length direction perpendicular to the upper main beam 11, and the first movable frame 21 is provided with a threaded hole matching the second waist-shaped hole 24. In actual application, the position of the second movable frame 22 is adjusted. After the position is determined, a stud is passed through the second waist-shaped hole 24 and the threaded hole of the first movable frame 21, so that the first movable frame 21 is connected and fixed with the second movable frame 22.
