Description

Technical Field

[0001] This application relates to the technical field of steel support equipment, and in particular to a steel support hoisting equipment. Background Technology

[0002] With the rapid development of cities, underground rail transit projects such as subways have become an important standard for measuring a city's development level. The construction of underground rail transit includes open-cut and cut-and-cover methods. While the open-cut method has the advantages of simple construction technology and high construction efficiency, it has a relatively large impact on surrounding traffic and is not suitable for areas with heavy traffic or high vehicle volume. The cut-and-cover method involves excavating the ground to a certain depth and then covering the opening of the pit with a cover slab, thus providing a passageway for vehicles and pedestrians.

[0003] During construction, after the ground is excavated to a certain depth, horizontal steel supports are installed to support the walls on both sides and reduce the risk of wall collapse after excavation. In the semi-cut-and-cover method, as shown in the diagram, the steel supports are typically composed of multiple pipes connected together. Therefore, the supporting pipes need to be hoisted into the pit one by one. The first pipe is connected to the wall and supported by a bracket. Subsequent pipes are hoisted into the pit and then connected sequentially until the steel support structure is formed. During pipe connection, the pipes are easily swayed during hoisting, increasing the difficulty of the connection process. Summary of the Invention

[0004] To improve the stability of pipeline connections, this application provides a steel support hoisting device.

[0005] The technical solution adopted in this application is as follows: A steel support hoisting device includes a hoisting part and a support part. The support part includes a lifting component and an adjusting component. The adjusting component is installed on the lifting component. The hoisting part is used to place pipes and can be hoisted onto the adjusting component. The lifting component can drive the adjusting component to move up and down in a vertical direction. The adjusting component can slide horizontally on the lifting component in a horizontal direction, and the sliding direction of the adjusting component is perpendicular to the distribution direction of the pipes.

[0006] By adopting the above technical solution, the support is placed in the foundation pit, the pipeline is placed on the hoisting part, and then hoisted onto the adjusting part. By adjusting the position of the adjusting part horizontally, the horizontal position of the pipeline can be adjusted. By adjusting the vertical height of the adjusting part by the lifting part, the vertical height of the pipeline can be adjusted. Therefore, the pipeline is easy to connect after hoisting, and it is also easy to adjust the height and horizontal direction according to the position deviation.

[0007] Optionally, the adjusting component includes a base plate and two frames connected to the base plate, with a space between the two frames, and the lifting part can be lifted onto the two frames; a driving source is installed between the base plate and the lifting component, and the driving source is used to drive the base plate to slide horizontally on the lifting component.

[0008] By adopting the above technical solution, the base plate is adjusted to a suitable position by the drive source, and the hoisting part is hoisted on the frame, so that the pipeline can be connected. If there is still a deviation, it can be finely adjusted by the drive source.

[0009] Optionally, the hoisting unit includes two hoisting plates and a support plate connected between the two hoisting plates; each hoisting plate is equipped with a clamping member, and a lifting part is installed on the hoisting plate. The lifting part slides up and down on the hoisting plate, and a reset member is installed between the hoisting plate and the lifting part. The lifting part and the clamping member are linked together. When hoisting is performed, the lifting part slides upward, the reset member is compressed, and the lifting part can drive the clamping member to clamp the pipe. When the reset member drives the lifting part to reset, the clamping member can release the positioning effect on the pipe.

[0010] By adopting the above technical solution, the pipeline is placed on the support plate, and then the clamping parts can clamp the pipeline during lifting, which makes it easier to lift the pipeline.

[0011] Optionally, the lifting part includes a lifting ring, a vertical rod connected to the lifting ring, and a trigger block connected to the outer wall of the vertical rod. The side wall of the trigger block has an inclined surface. The lifting plate has a receiving groove for the trigger block to slide. The reset member is installed on the outer wall of the vertical rod, with one end abutting against the inner top surface of the receiving groove and the other end abutting against the trigger block. The sliding groove and the receiving groove are connected. An extension rod is provided on the sliding block, and the extension rod abuts against the inclined surface of the trigger block. During lifting, the trigger block can move upward and push the sliding block to slide through the extension rod, thereby causing the clamping plate to press against the side wall of the pipe.

[0012] By adopting the above technical solution, when lifting, the lifting ring moves upward and simultaneously drives the trigger block to move upward, thereby pushing the sliding block to slide through the extension rod, so that the clamping plate is pressed against the side wall of the pipe, thereby positioning the pipe.

[0013] Optionally, the support plate is an arc-shaped structure with the arc facing upwards.

[0014] By adopting the above technical solution, the support plate has an arc-shaped structure, which makes it easier to place pipes.

[0015] Optionally, a sliding plate is slidably installed between the two lifting plates, and the sliding plate is located below the support plate; the support plate has a slot, and the sliding plate is rotatably provided with multiple balls corresponding to the position of the slot. When the lifting part is lifted onto the frame, the sliding plate can be pressed against the frame and slide upward, so that the balls can partially extend from the slot out of the surface of the support plate.

[0016] By adopting the above technical solution, after the hoisting part is placed on the frame, the sliding plate moves upward, causing the ball bearings to abut against the pipe. This makes it easier to push the pipe along the axial direction during pipe connection, thus facilitating the connection.

[0017] Optionally, the lifting plate is provided with a clearance groove, the end of the sliding plate is provided with an extension block extending into the clearance groove, and the bottom surface of the extension block is provided with an abutment block. The abutment block extends downward through the bottom surface of the lifting plate, and a second elastic member is installed between the upper surface of the extension block and the inner top surface of the clearance groove. The second elastic member drives the sliding plate to move downward so that the abutment block has a portion that extends beyond the bottom surface of the lifting plate.

[0018] By adopting the above technical solution, the hoisting part is placed on the frame, which can squeeze the contact block and thus push the sliding plate to slide.

[0019] Optionally, an inclined plate extending downwards is provided on the side opposite to the hoisting plate.

[0020] By adopting the above technical solution, the lifting unit can be more easily hoisted onto the frame under the guidance of the inclined plate.

[0021] In summary, this application includes at least one of the following beneficial effects: 1. The pipe is placed on the hoisting unit and suspended on the adjusting component. The vertical and horizontal positions of the pipe can be adjusted by the adjusting and lifting components, making it easier to connect the pipe. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a steel support hoisting device. (Refer to...) Figure 1 and Figure 2 The hoisting equipment includes a hoisting section 1 and a support section 2. The support section 2 is placed in the excavated foundation pit. The hoisting section 1 is used to place the pipes. After the pipes are placed on the hoisting section 1, they are hoisted onto the support section 2, and then the pipes are connected. During construction, the connected pipes are first supported by erected frames to facilitate subsequent pipe connections.

[0026] Reference Figure 2 and Figure 3 The support part 2 includes a lifting member 21 and an adjusting member 22. The adjusting member 22 is mounted on the lifting member 21. In this embodiment, the lifting member 21 is preferably a scissor mechanism, and the adjusting member 22 is mounted on the scissor mechanism. The specific structure of the scissor mechanism is prior art and will not be described in detail in this embodiment. The adjusting member 22 can be driven to move up and down in the vertical direction by the lifting member 21, so as to adjust its vertical height. The adjusting member 22 includes a base plate 221 and two frames 222 mounted on the base plate 221. The two frames 222 are parallel to each other and there is a certain distance between the two frames 222. The hoisting part 1 is hoisted on the two frames 222. A drive source 3 is installed between the base plate 221 and the lifting member 21. The drive source 3 is used to drive the base plate 221 to slide on the lifting member 21, and its sliding direction is perpendicular to the distribution direction of the pipe. Therefore, if there is a deviation in the horizontal direction when the pipe is connected, the position of the pipe can be adjusted by adjusting the adjusting member 22.

[0027] In a further embodiment, the drive source 3 includes a screw 31 rotatably connected to the lifting member 21. The bottom surface of the base plate 221 is threadedly connected to the screw 31. A motor 32 connected to the screw 31 is also installed on the lifting member 21, thereby driving the screw 31 to rotate. A guide block and guide groove are also installed between the base plate 221 and the upper surface of the lifting member 21 for guidance. The guide block and guide groove can be a dovetail groove, a T-groove, etc., so that the rotation of the screw 31 can drive the rotation of the base plate 221. In other embodiments, the base plate 221 can also be guided by a guide rod.

[0028] Reference Figure 3 and Figure 4 The hoisting unit 1 includes two hoisting plates 101 and a support plate 102 connecting the two hoisting plates 101. When the hoisting unit 1 is hoisted onto the frame 222, the frame 222 and the hoisting plates 101 correspond to each other, thereby allowing the frame 222 to support the hoisting unit 1. Clamping members 4 are installed on each of the hoisting plates 101, symmetrically arranged. When the pipe is placed on the support plate 102, the clamping members 4 can abut against both sides of the pipe during hoisting, thereby positioning the pipe. A lifting part 5 is slidably installed on the hoisting plate 101, sliding up and down on the hoisting plate 101. Figure 5 A reset component 6 is also installed inside the lifting plate 101. Under the action of the reset component 6, the lifting part 5 is housed in the lifting plate 101. During lifting, the hook is connected to the lifting part 5, and the lifting part 5 slides out of the lifting plate 101. The reset component 6 is compressed, thus providing the repositioning force for the lifting part. The lifting part 5 and the clamping component 4 are linked. When the lifting part 5 slides out, it drives the clamping component 4 to clamp onto the side wall of the pipe. When the lifting part 1 is placed on the frame 222, the reset component 6 drives the lifting part 5 to reset, and the clamping component 4 releases its positioning effect on the pipe.

[0029] In a further embodiment, refer to Figure 4 and Figure 5 The clamping member 4 includes a clamping plate 41 and hinge rods 42 hinged to both ends of the clamping plate 41. Sliding blocks 7 are slidably mounted on the lifting plate 101, with each sliding block 7 corresponding to a hinge rod 42, and the end of the hinge rod 42 away from the clamping plate 41 is hinged to the sliding block 7. The clamping plate 41 is connected to the sliding block 7 via the hinge rods 42, forming an isosceles trapezoidal structure. When the pipe is placed on the support plate 102, the two sliding blocks 7 on the lifting plate 101 move closer to each other, allowing the clamping plate 41 to move away from the lifting plate 101, thus pressing the clamping plate 41 against the pipe.

[0030] A sliding groove 8 is provided on the lifting plate 101, and the sliding block 7 slides in the sliding groove 8. The sliding groove 8 extends to the surface of the lifting plate 101, and the hinge rod 42 can extend into the sliding groove 8 and connect with the sliding block 7. The lifting part 5 includes a lifting ring 51, a vertical rod 52 fixedly connected to the lifting ring 51, and a trigger block 53 fixed to the outer wall of the vertical rod 52. A receiving groove 20 is provided on the lifting plate 101, and the trigger block 53 slides in the receiving groove 20. The reset member 6 is a spring, which is sleeved on the side wall of the vertical rod 52. The upper end of the spring abuts against the inner top surface of the receiving groove 20, and the lower end abuts against the trigger block 53. When the vertical rod 52 slides upward, the spring is compressed, thereby increasing the reset force of the trigger block 53.

[0031] The sliding groove 8 and the receiving groove 20 are interconnected, and an extension rod 10 is fixed on the sliding block 7. The end of the extension rod 10 can extend into the receiving groove 20. A first elastic element 9 is also installed in the sliding groove 8. The first elastic element 9 is preferably a spring. Under the action of the first elastic element 9, the end of the extension rod 10 can abut against the side wall of the trigger block 53. The trigger block 53 is preferably a frustum structure, and the trigger block 53 is smaller at the top and larger at the bottom, so that the side wall of the trigger block 53 has an inclined surface. Under the action of the first elastic element 9, the end of the extension rod 10 abuts against the side wall of the trigger block 53. When lifting, the hook is connected to the lifting ring 51, and then lifting is performed. The lifting ring 51 slides upward and drives the trigger block 53 to slide upward. The reset element 6 is compressed, and the trigger block 53 pushes the extension rod 10 to slide, so that the sliding block 7 slides into the sliding groove 8. The first elastic element 9 is compressed, and the clamping plate 41 moves away from the lifting plate 101 and abuts against the pipe.

[0032] Preferably, the side of the clamping plate 41 opposite to the lifting plate 101 is bonded with an anti-slip layer to improve the positioning effect on the pipe. After the lifting part 1 is lifted onto the frame 222, under the elastic force of the reset member 6, the trigger block 53 slides downward to reset, and the sliding block 7 is reset under the action of the first elastic member 9, thus releasing the positioning effect of the clamping plate 41 on the pipe. Furthermore, to facilitate the lifting part 1 being lifted onto the frame 222, an inclined plate 18 extending downward is provided on the side of the lifting plate 101 opposite to it. The two inclined plates 18 form a flared downward structure, making it easier to place the lifting plate 101 onto the frame 222 under the guidance of the inclined plates 18. In addition, a waist-shaped groove 19 is provided on the inclined plate 18, and bolts are passed through the waist-shaped groove 19 and threaded onto the frame 222, with the bolt heads pressing against the inclined plate 18, thereby further reinforcing the lifting plate and improving the stability of the pipe connection.

[0033] In a further embodiment, refer to Figure 4 and Figure 5The support plate 102 has an upward-facing arc-shaped structure, which improves the stability of the pipe when placed on it. A sliding plate 11 is slidably installed between the two lifting plates 101, located below the support plate 102. The sliding plate 11 is also arc-shaped. Multiple slots 12 are spaced apart on the support plate 102, and multiple ball bearings 13 are rotatably connected to the sliding plate 11 corresponding to the slots 12. When the sliding plate 11 slides upward, the ball bearings 13 can pass through the slots 12 and partially extend onto the surface of the support plate 102. This facilitates easier axial pushing of the pipe during connection.

[0034] Extension blocks 15 are fixed to both sides of the sliding plate 11. Multiple extension blocks 15 can be fixed to each side of the sliding plate 11. In this embodiment, one extension block 15 is used for description. A relief groove 14 is provided on the lifting plate 101. The extension block 15 extends into the relief groove 14 and slides in the relief groove 14, thereby driving the sliding plate 11 to slide. An abutment block 16 is fixed to the side of the extension block 15 away from the support plate 102. The abutment block 16 passes through the bottom surface of the relief groove 14. A second elastic element 17 is installed on the extension block 15. The second elastic element 17 is a spring, one end of which is connected to the upper surface of the extension block 15, and the other end is connected to the inner top surface of the relief groove 14. Under the action of the second elastic element 17, the lower end of the abutment block 16 extends beyond the lower surface of the lifting plate 101. When the lifting plate 101 is hoisted onto the frame 222, the contact block 16 is pressed against the surface of the frame 222 and slides into the relief groove 14, thereby causing the sliding plate 11 to slide and allowing the ball bearing 13 to extend from the slot 12 to the surface of the support plate 102. Furthermore, when the lifting part 1 is placed on the ground, the lowest position of the sliding plate 11 can abut against the ground, allowing the ball bearing 13 to also extend from the slot 12, making it easier to adjust the position of the pipe when it is placed on the support plate 102.

[0035] The implementation principle of a steel support hoisting device in this application embodiment is as follows: the pipe is first placed on the support plate 102, and then hoisted by a hoist. During hoisting, the clamping part 4 is pressed against the pipe for positioning. The hoisting plate 101 is hoisted on the frame 222, and the sliding plate 11 slides upward so that the ball bearing 13 can abut against the side wall of the pipe, thereby facilitating the connection of the pipe.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
