Description

Technical Field

[0001] This utility model relates to the field of pipe gallery hoisting construction technology, and in particular to a hoisting device for integrated pipe gallery construction. Background Technology

[0002] Integrated utility tunnels can integrate various engineering pipelines such as electricity, communications, gas, heating, and water supply and drainage, and are equipped with dedicated inspection ports, hoisting ports, and monitoring systems, implementing unified planning, design, construction, and management. During the construction of integrated utility tunnels, prefabricated tunnel segments are currently mainly spliced ​​together one by one using hoisting equipment.

[0003] For example, Chinese patent "CN222410798U" discloses "a prefabricated pipe gallery hoisting device." This device uses multiple tracks to flexibly hoist pipe galleries in different positions. It also includes a gantry frame for installing hoisting components and a hoisting frame and telescopic rods to shorten or extend the frame according to the size of the pipe gallery, thus adapting to the hoisting needs. However, when the construction section of the pipe gallery has a certain slope, it is impossible to adjust the angle of the hoisted pipe gallery, reducing the efficiency of connecting adjacent pipe galleries. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting device for the construction of integrated utility tunnels, which solves the problem that existing technologies cannot adjust the angle of the hoisted utility tunnel.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

The adjusting assembly is located in the adjusting cylinder and connected to the hoisting rope, and is used to adjust the length of the hoisting rope outside the adjusting cylinder.

[0010] And a drive assembly, located on the hanger and connected to two adjusting cylinders, for controlling the distance between the two adjusting cylinders.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In this scheme, with the cooperation of the adjusting cylinder and the hoisting unit, the hoisting points on the pipe gallery can be connected by hoisting ropes. The external crane lifts the gantry, thereby hoisting the pipe gallery by the hoisting ropes and moving the gantry to splice the pipe gallery to the designated position.

This facilitates the splicing construction of the pipe gallery even when there is a slope on the construction site. Moreover, under the action of the drive component, the distance between the two adjusting cylinders can be adjusted, thereby changing the horizontal position of the ends of the two hoisting ropes to accommodate the hoisting of pipe galleries of different lengths.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] This utility model embodiment proposes a lifting device for the construction of integrated utility tunnels, including:

[0031] The hanger 1 has a channel 102 extending through both ends along its axial direction;

[0032] Adjusting cylinder 2, two adjusting cylinders 2 are respectively installed at both ends of channel 102;

[0033] The hoisting unit includes a hoisting rope 3 and an adjusting component. One end of the hoisting rope 3 is located inside the adjusting cylinder 2, and the other end extends through the outside of the adjusting cylinder 2. The adjusting component is located in the adjusting cylinder 2 and connected to the hoisting rope 3, and is used to adjust the length of the hoisting rope 3 outside the adjusting cylinder 2.

[0034] And a drive assembly, located on the hanger 1 and connected to two adjusting cylinders 2, for controlling the distance between the two adjusting cylinders 2.

[0035] In the embodiments of this utility model, such as Figure 1 As shown, the hanger 1 is hollow and hollow, forming a channel 102 with openings at both ends. Two adjusting cylinders 2 are respectively inserted at both ends of the channel 102, allowing the adjusting cylinders 2 to move within the channel 102. The end of the lifting rope 3 extending out of the adjusting cylinder 2 falls naturally. When the drive component moves the two adjusting cylinders 2, it can change the position of the projection of the adjusting cylinders 2 on the pipe rack. It is not affected by the length of the pipe rack, and can keep the lifting rope 3 aligned with the lifting point of the pipe rack. This ensures that the lifting rope 3 is in a vertical state when lifting the pipe rack, thus ensuring the stability of the pipe rack during lifting.

[0036] like Figure 2As shown, when hoisting the utility tunnel, the lengths of the hoisting ropes 3 extending from the two adjusting cylinders 2 are the same. When the hoisting frame 1 is lifted by the crane, the utility tunnel is in a horizontal state under the simultaneous hoisting of the two hoisting ropes 3, which is suitable for the splicing construction of the utility tunnel on a horizontal plane. When a certain slope is required in the construction area, there are two operating methods. One is to install an angled jig at the construction site, hoist the pipe rack onto the jig so that its angle matches the jig's angle and the slope. Then, connect two lifting ropes 3 to the pipe rack's hoisting point. While the crane is lifting, the length of one of the lifting ropes 3 can be adjusted to ensure both ropes 3 are taut before lifting. An adjustment component can be installed in only one adjusting cylinder 2, or, to accommodate different placement angles, adjustment components can be installed in both adjusting cylinders 2 to adjust the lifting ropes 3 of one or the other. The second method is to first hoist the pipe rack. Once the pipe rack is off the ground, the length of one end of the corresponding lifting rope 3 is adjusted using the adjustment component in the adjusting cylinder 2 until the pipe rack meets the preset installation angle.

[0037] Based on the above solutions, such as Figure 4 As shown, the adjustment assembly includes a jack 6, which is located inside the adjustment cylinder 2. The telescopic end of the jack 6 is equipped with a slider 601, which is slidably mounted on the adjustment cylinder 2 and fixedly connected to the end of the hoisting rope 3. By controlling the extension or retraction of the telescopic end of the jack 6, the slider 601 slides inside the adjustment cylinder 2, thereby causing the slider 601 to drive the end of the hoisting rope 3 to move inside the adjustment cylinder 2, thus changing the length of the hoisting rope 3 extending out of the adjustment cylinder 2. The jack 6 has a large thrust and a fast response speed, which can quickly complete the adjustment of the length of the hoisting rope 3 and improve the efficiency of hoisting preparation.

[0038] Based on the above solutions, such as Figure 1 As shown, the driving component includes:

[0039] Adjusting blocks 201, both adjusting blocks 201 are slidably mounted on the hanger 1 and respectively connected to the two adjusting cylinders 2;

[0040] A bidirectional adjustment component is provided on the hanger 1 and connected to two adjustment blocks 201.

[0041] The portion of the lifting rope 3 outside the adjusting cylinder 2 naturally descends under its own weight, thus making the position of the end of the adjusting cylinder 2 the vertical lifting position of the lifting rope 3. Due to the length of the pipe gallery, the position of the lifting ring embedded in the pipe gallery will also change. In order to prevent the lifting rope 3 from tilting after connecting to the lifting ring, the two adjusting blocks 201 can be adjusted synchronously under the action of the bidirectional adjusting component, so as to realize the synchronous adjustment of the positions of the two adjusting cylinders 2 until the lifting rope 3 corresponds to the lifting ring in its natural state and is connected. The aforementioned bidirectional adjusting component can be a bidirectional jack or a motor and threaded component transmission.

[0042] Secondly, each of the two lifting ropes 3 is equipped with a hook 301 at its end, which facilitates direct connection to the lifting ring on the pipe rack via the hook 301, improving installation efficiency. At the same time, both ends of the adjusting cylinder 2 are equipped with a limit wheel 7, and the lifting rope 3 is mounted on the limit wheel 7, which prevents the lifting rope 3 from directly rubbing against the end of the adjusting cylinder 2 during adjustment or lifting. Since the limit wheel 7 can rotate freely, the lifting rope 3 slides more smoothly on it, reducing wear and extending the service life of the lifting rope 3.

[0043] To reduce the area occupied by the equipment on the hanger 1, the bidirectional adjustment component includes:

[0044] Dual-axis motor 5, which is fixedly mounted on the hanger 1;

[0045] Two lead screws 501 are respectively located at the two output ends of the dual-axis motor 5, and two adjusting blocks 201 are respectively threadedly connected to the two lead screws 501.

[0046] When the dual-axis motor 5 is started, the two output shafts of the dual-axis motor 5 rotate synchronously. Since the threads of the two lead screws 501 are turned in opposite directions, under the drive of the dual-axis motor 5, the two adjusting blocks 201 can be controlled to move closer or further away from each other by the two lead screws 501 respectively, thereby realizing the adjustment of the two adjusting cylinders 2.

[0047] Specifically, such as Figure 4 As shown, both ends of the hanger 1 are provided with limit seats 101. The ends of the two lead screws 501 are respectively rotatably mounted on the two limit seats 101, which can bear the other end of the lead screw 501 and ensure the stability of the lead screw 501 during transmission.

[0048] Specifically, such as Figure 1 As shown, both ends of the hanger 1 are provided with mounting bases 4, and both mounting bases 4 are provided with lifting rings 401. Under the action of the lifting rings 401, the lifting rings 401 serve as load-bearing connection points and can be directly connected to lifting equipment such as cranes through connecting ropes.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
