Description

Technical Field

[0001] This application relates to the field of integrated utility tunnel installation and construction technology, specifically to an integrated utility tunnel segment hoisting device. Background Technology

[0002] Integrated utility tunnels are underground urban pipeline corridors, essentially tunnel spaces built beneath a city to integrate various engineering pipelines such as electricity, communications, gas, heating, and water supply and drainage. They are equipped with dedicated inspection ports, hoisting ports, and monitoring systems, and are subject to unified planning, design, construction, and management. They are vital infrastructure and a "lifeline" for ensuring the operation of a city. During construction, prefabricated tunnel sections are typically hoisted into the foundation pit, assembled there, and then backfilled. Current hoisting methods often use cranes with lifting slings. However, because lifting slings are flexible, their stability is poor, causing the tunnel sections to sway during movement, potentially leading to collisions and posing certain dangers. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a segmented hoisting device for integrated utility tunnels, comprising a fixed base, a slewing mechanism, a drive mechanism, a lifting mechanism, and a gripping mechanism. The slewing mechanism is fixedly connected to the fixed base and drives the lifting mechanism to rotate. The drive mechanism is movably connected to the fixed base and can selectively drive either the slewing mechanism or the lifting mechanism. The lifting mechanism is rotatably connected to the slewing mechanism and drively connected to the drive mechanism, and is used to lift or lower the gripping mechanism. The gripping mechanism includes a lifting beam and two clamping assemblies. The middle of the lifting beam is fixedly connected to the lifting mechanism, and the two clamping assemblies are respectively disposed at both ends of the lifting beam. Each clamping assembly includes two clamps that can move away from or close to each other, and the clamps are used to grip segments of the integrated utility tunnel.

[0004] When a segment of the utility tunnel needs to be grasped, the drive mechanism drives the lifting mechanism to move. The lifting mechanism then lowers the grasping mechanism, causing the two clamps in the clamping assembly to move away from each other, allowing the utility tunnel segment to be accommodated between the two clamps. Once the two clamps come together and clamp the utility tunnel segment, the lifting mechanism can lift the segment and move it to the installation position via the rotation mechanism. Because there is a rigid constraint between the clamps and the utility tunnel segment, it is not easy for the segment to sway when moving, thus greatly improving stability and safety.

[0005] In some embodiments, the clamping assembly further includes two clamping links, one end of each link being hinged together by a first hinge pin, and the other end of each link being hinged to one of the clamps. The first hinge pin is connected to the end of the lifting beam. Each clamp has a straight segment and an arc segment. The ends of the two straight segments are hinged to the ends of the clamping links, and the middle sections of the two straight segments intersect each other and are hinged together by a second hinge pin. The two straight segments are rotatable about the second hinge pin, and the two clamping links and the two straight segments form a quadrilateral. When the second hinge pin is close to the first hinge pin, the two arc segments separate; when the second hinge pin is away from the first hinge pin, the two arc segments move closer together.

[0006] When the two clamps tighten around the utility tunnel segment and lift it upwards, gravity causes the second hinge axis to move away from the first hinge axis, further tightening the segment with the arc segments of the two clamps, making the hoisting more stable and safe. When the segment is lowered, it moves against the second hinge axis and then against the first hinge axis, causing the arc segments of the two clamps to move away from each other and releasing the segment.

[0007] Furthermore, the clamping assembly also includes a limiting guide rod. One end of the limiting guide rod is vertically fixed to the end of the lifting beam, and the other end extends downward. The limiting guide rod has a limiting guide groove along its length. One end of the second hinge shaft is inserted into the limiting guide groove and can slide up and down along the limiting guide groove. The limiting guide rod can limit the swing of the clamp in the direction perpendicular to the limiting guide groove, so that a rigid constraint is formed between the clamp and the lifting beam, further improving the stability of the hoisting.

[0008] As a further improvement, the clamping assembly also includes a clamping synchronizing rod, the two ends of which are respectively connected to the second hinge shafts of the two clamping assemblies. The clamping synchronizing rod can drive the two clamping assemblies to move synchronously, thereby enabling the two pairs of clamps to simultaneously clamp the integrated utility tunnel sections, further improving the stability of the hoisting.

[0009] Furthermore, the clamping assembly also includes a clamp extension rod. The arc segment of the clamp has a telescopic guide groove. One end of the clamp extension rod is accommodated in the telescopic guide groove, and the other end extends out of the telescopic guide groove. The clamp extension rod can slide along the telescopic guide groove to adjust the length exposed in the telescopic guide groove. After gripping the integrated utility tunnel segment, the clamp extension rod extends out of the telescopic guide groove, thereby increasing the contact area between the clamp and the integrated utility tunnel segment, increasing the circumference of the clamped integrated utility tunnel segment, and making the hoisting process safer.

[0010] Furthermore, an anti-slip pad is provided on the inner side of the clamp extension rod. The anti-slip pad can effectively increase the friction between the integrated utility tunnel section and the clamp, preventing it from slipping between the clamps when the integrated utility tunnel section is tilted.

[0011] In some embodiments, the lifting mechanism includes a transmission column, a transmission gear, a transmission connecting beam, a transmission wheel, a driven wheel, a transmission belt, and a lifting rod. The transmission gear is fixedly sleeved on the transmission column and is drively connected to the drive mechanism. One end of the transmission connecting beam is rotatably connected to the rotary mechanism, and the other end is rotatably connected to the transmission column, extending further away from the rotary mechanism. The bottom of the lifting rod passes through the end of the transmission connecting beam and is fixedly connected to the lifting beam. The transmission wheel is fixedly connected to the transmission column. The driven wheel is sleeved on the lifting rod, its inner wall is threaded to the lifting rod, and its bottom is rotatably connected to the transmission connecting beam. The transmission belt matches the driven wheel and the transmission wheel, and drives the transmission wheel and the driven wheel to rotate synchronously. When the driven wheel rotates, it drives the lifting rod to move up and down vertically, thereby driving the gripping mechanism to move up and down.

[0012] In some embodiments, the rotary mechanism includes a fixed column, one end of which is vertically fixed to the fixed base, and the other end is rotatably connected to the transmission connecting beam. A rotary gear is fixedly sleeved on the fixed column, the distance between the rotary gear and the fixed base being less than the distance between the transmission gear and the fixed base. The rotary gear is drively connected to the drive mechanism. Since the rotary gear is fixedly connected to the base via the fixed column, when the drive mechanism operates, the drive mechanism and the lifting mechanism move around the fixed column, achieving a rotary motion. In conventional designs, the rotary mechanism typically rotates itself, thereby driving other mechanisms to rotate, which often requires a complex rotary support structure. The design provided in this application simplifies the rotary structure and reduces production costs.

[0013] In some embodiments, the driving mechanism includes a drive motor, one end of which is connected to a drive shaft. The drive shaft is parallel to the transmission column, and a drive gear is slidably mounted on the drive shaft. The drive gear rotates synchronously with the drive shaft. The drive shaft has a first position and a second position along its axial direction, and the drive gear can slide up and down along the drive shaft to switch between the first position and the second position. In the first position, the drive gear meshes with the rotary gear, and in the second position, it meshes with the transmission gear. This design allows one drive motor to drive two mechanisms, simplifying the drive mechanism.

[0014] Specifically, the drive mechanism further includes: a sliding base, a gear sleeve, a shift pin, a shift lever, a positioning rod, and two positioning rings. The sliding base is fixedly connected to the drive motor, and the sliding base is slidably connected to the fixed base. The gear sleeve is fixedly connected to the drive gear, and the gear sleeve is sleeved on the drive shaft. The gear sleeve can slide up and down along the axial direction of the drive shaft and can rotate synchronously with the drive shaft. The shift pin is movably connected to the gear sleeve and can slide along the circumference of the gear sleeve. The middle position of the shift lever is rotatably connected to the sliding base through a third hinge. One end of the shift lever is provided with a first groove for accommodating the shift pin, and the other end is provided with a second groove. One end of the positioning rod is vertically fixed to the sliding base, and the other end extends out from the second groove. The two positioning rings are sleeved and threadedly connected to the positioning rod. The two positioning rings are respectively located on both sides of the shift lever and are used to fix the shift lever.

[0015] When it is necessary to switch the position of the drive gear, turn the positioning ring so that the shift lever can rotate around the third hinge axis, and move the first slide groove up and down in the vertical direction. This drives the drive gear to switch between the first position and the second position through the shift pin and the gear sleeve, so as to select whether to mesh with the transmission gear or the rotary gear.

[0016] The beneficial effects of this application are as follows: This application provides a segmented hoisting device for integrated utility tunnels, including a fixed base, a slewing mechanism, a drive mechanism, a lifting mechanism, and a gripping mechanism. The slewing mechanism is fixedly connected to the fixed base, and the drive mechanism is movably connected to the fixed base. The drive mechanism can selectively drive either the slewing mechanism or the lifting mechanism. The lifting mechanism is rotatably connected to the slewing mechanism and is drively connected to the drive mechanism. The lifting mechanism is used to lift or lower the gripping mechanism. The gripping mechanism includes two clamping components. When a segment of the integrated utility tunnel needs to be gripped, the drive mechanism drives the lifting mechanism to move, and the lifting mechanism drives the gripping mechanism to descend, so that the segment of the integrated utility tunnel is housed inside the clamping components. The clamps of the clamping components can clamp the segment of the integrated utility tunnel. Because there is a rigid constraint between the clamps and the segment of the integrated utility tunnel, it is not easy to shake when moving the segment of the integrated utility tunnel, thus greatly improving stability and safety.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other alternative implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Embodiments of this application provide a segmented hoisting device for integrated utility tunnels, such as... Figure 1 As shown, the system includes a fixed base 1, a rotating mechanism 2, a drive mechanism 3, a lifting mechanism 4, and a gripping mechanism 5. The rotating mechanism 2 is fixedly connected to the fixed base 1 and drives the lifting mechanism 4 to rotate. The drive mechanism 3 is movably connected to the fixed base 1 and can selectively drive either the rotating mechanism 2 or the lifting mechanism 4. The lifting mechanism 4 is rotatably connected to the rotating mechanism 2 and is also drive-connected to the drive mechanism 3. The lifting mechanism 4 is used to lift or lower the gripping mechanism 5. The gripping mechanism 5 includes a lifting beam 51 and two clamping assemblies 52. The middle of the lifting beam 51 is fixedly connected to the lifting mechanism 4. The two clamping assemblies 52 are respectively located at both ends of the lifting beam 51. Each clamping assembly 52 includes two clamps 521 that can move away from or close to each other. The clamps 521 are used to grip sections of the integrated utility tunnel.

[0024] When a section of the utility tunnel needs to be grasped, the drive mechanism 3 drives the lifting mechanism 4 to move. The lifting mechanism 4 then lowers the grasping mechanism 5, and the two clamps 521 in the clamping assembly 52 move away from each other, allowing the utility tunnel section to be accommodated between the two clamps 521. Once the two clamps 521 move closer together and clamp the utility tunnel section, the lifting mechanism 4 can lift the utility tunnel section and use the rotation mechanism 2 to move the utility tunnel section to the installation position. Because there is a rigid constraint between the clamps 521 and the utility tunnel section, it is not easy to shake when moving the utility tunnel section, thus greatly improving stability and safety.

[0025] Specifically, in the embodiments of this application, such as Figure 2As shown, the clamping assembly 5 also includes two clamping links 523. One end of each clamping link 523 is hinged together via a first hinge pin 529, and the other end is hinged to a clamp 521. The first hinge pin 529 is connected to the end of the lifting beam 51. Each clamp 521 has a straight segment 5211 and an arc segment 5212. The ends of the two straight segments 5211 are hinged to the ends of the clamping links 523, and the two straight segments 5211 intersect each other and are hinged together via a second hinge pin 522. The two straight segments 5211 can rotate around the second hinge pin 522, and the two clamping links 523 and the two straight segments 5211 form a quadrilateral. When the second hinge pin 522 is close to the first hinge pin 529, the two arc segments 5212 separate; when the second hinge pin 522 is away from the first hinge pin 529, the two arc segments 5212 move closer together.

[0026] When the two clamps 521 clamp the integrated utility tunnel segment and lift it upwards, gravity causes the second hinge axis to move away from the first hinge axis 529, thereby further clamping the integrated utility tunnel segment with the arc segments 5212 of the two clamps 521, making the hoisting more stable and safe. When the integrated utility tunnel segment is lowered, the segment will move against the second hinge axis and the first hinge axis 529, causing the arc segments 5212 of the two clamps 521 to move away from each other, releasing the integrated utility tunnel segment.

[0027] Figure 2 The structure of the clamping assembly 52 shown is not the only way to achieve the two clamps 521 moving away from or close to each other in this application. The two clamps 521 can also move away from or close to each other by setting up a hydraulic mechanism or by using a screw and a threaded hole. These methods are all existing technologies and will not be described in detail here.

[0028] Furthermore, such as Figure 2 As shown, the clamping assembly 52 also includes a limiting guide rod 524. One end of the limiting guide rod 524 is vertically fixed to the end of the lifting beam 51, and the other end extends downward. The limiting guide rod 524 is provided with a limiting guide groove 5241. One end of the second hinge shaft 522 is inserted into the limiting guide groove 5241 and can slide up and down along the limiting guide groove 5241. The limiting guide rod 524 can limit the swing of the clamp 521 in the direction perpendicular to the limiting guide groove 5241, so that a rigid constraint is formed between the clamp 521 and the lifting beam 51, further improving the stability of the hoisting.

[0029] As a further improvement, the clamping assembly 52 also includes a clamping synchronizing rod 525, the two ends of which are respectively connected to the second hinge pins 522 of the two clamping assemblies 52. The clamping synchronizing rod 525 can drive the two clamping assemblies 52 to move synchronously, so that the two pairs of clamps 521 can clamp the integrated pipe gallery sections at the same time, further improving the stability of the hoisting.

[0030] As a further improvement, the clamping assembly 52 also includes a clamp extension rod 526. The arc segment 5212 of the clamp 521 has a telescopic guide groove 5213. One end of the clamp extension rod 526 is accommodated in the telescopic guide groove 5213, and the other end extends out of the telescopic guide groove 5213. The clamp extension rod 526 can slide along the telescopic guide groove 5213 to adjust the length exposed in the telescopic guide groove 5213. After gripping the integrated utility tunnel segment, the clamp extension rod 526 extends out of the telescopic guide groove 5213, thereby increasing the contact area between the clamp 521 and the integrated utility tunnel segment, increasing the circumference of the clamped integrated utility tunnel segment, and making the hoisting process safer.

[0031] Furthermore, an anti-slip pad 527 is provided on the inner side of the clamp extension rod 526. The anti-slip pad 527 can effectively increase the friction between the integrated utility tunnel section and the clamp 521, preventing the integrated utility tunnel section from slipping off the clamp 521 when tilted.

[0032] Clamping assembly 52 may also include a buffer mechanism 528, such as Figure 2 As shown, a buffer spring sleeve 5281 is provided on the lower side of the clamping synchronization rod 525. A buffer spring 5282 is housed within the buffer spring sleeve 5281. The buffer spring 5282 is connected to a buffer block 5283, and a buffer pad 5284 is also provided on the buffer block 5283. The buffer mechanism 528 is used to prevent rigid collision between the integrated pipe gallery segment and the clamping assembly 52 when the gripping mechanism 5 descends, thus protecting the clamping assembly 52. ​​The buffer mechanism 528 can also use other types of buffers such as polyurethane buffers or hydraulic buffers to achieve the buffering function.

[0033] In the embodiments of this application, such as Figure 3 As shown, the lifting mechanism 4 includes a transmission column 41, a transmission gear 42, a transmission connecting beam 43, a transmission wheel 44, a driven wheel 45, a transmission belt 46, and a lifting rod 47. The transmission gear 42 is fixedly sleeved on the transmission column 41 and is connected to the drive mechanism. One end of the transmission connecting beam 43 is rotatably connected to the rotary mechanism, and the other end is rotatably connected to the transmission column 41, extending further away from the rotary mechanism. The bottom of the lifting rod 47 passes through the end of the transmission connecting beam 43 and is fixedly connected to the lifting beam. The transmission wheel 44 is fixedly connected to the transmission column 41. The driven wheel 45 is sleeved on the lifting rod 47, its inner wall is threaded to the lifting rod 47, and its bottom is rotatably connected to the transmission connecting beam 43. The transmission belt 46 matches the driven wheel 45 and the transmission wheel 44, and is used to drive the transmission wheel 44 and the driven wheel 45 to rotate synchronously. When the driven wheel 45 rotates, it can drive the lifting rod 47 to move up and down in the vertical direction, thereby driving the gripping mechanism 5 to move up and down.

[0034] There are many specific structural forms for the drive wheel 44, driven wheel 45, and drive belt 46, such as sprocket and chain, pulley and belt drive, gear and flexible rack, etc.

[0035] The lifting mechanism 4 can also drive the gripping mechanism 5 to lift and lower using other structural methods, such as using a gear and rack mechanism to convert rotary motion into linear motion, or using a hydraulic cylinder to drive the lifting rod to move up and down. Various transmission methods can also be used, such as helical gear transmission, which are existing technologies and will not be elaborated upon here.

[0036] In the embodiments of this application, such as Figure 3 As shown, the rotary mechanism 2 includes a fixed column 21, one end of which is vertically fixed to the fixed base 1, and the other end is rotatably connected to the transmission connecting beam 43. A rotary gear 22 is fixedly sleeved on the fixed column 21. The distance between the rotary gear 22 and the fixed base 1 is less than the distance between the transmission gear 42 and the fixed base 1. The rotary gear 22 is connected to the drive mechanism 3. Since the rotary gear 22 is fixed, when the drive mechanism 3 works, the drive mechanism 4 and the lifting mechanism 4 move around the fixed column 21 to achieve the rotary action. In conventional designs, the rotary mechanism usually rotates itself, thereby driving other mechanisms to rotate, which often requires the design of a complex rotary support structure. The design scheme provided in this application simplifies the rotary structure and reduces production costs.

[0037] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the drive mechanism 3 includes a drive motor 31, one end of which is connected to a drive shaft 32. The drive shaft 32 is parallel to the transmission column 41. A drive gear 33 is slidably mounted on the drive shaft 32. The drive gear 33 rotates synchronously with the drive shaft 32. The drive shaft 32 has a first position and a second position along its axial direction. The drive gear 33 can slide up and down along the drive shaft 32 to switch between the first and second positions. In the first position, the drive gear 33 meshes with the rotary gear 22. In the second position, the drive gear 33 meshes with the transmission gear 42. This design allows one drive motor to drive two mechanisms, simplifying the drive mechanism.

[0038] Specifically, such as Figure 4As shown, the drive mechanism 3 also includes: a sliding base 34, a gear sleeve 35, a shift pin 36, a shift lever 37, a positioning rod 38, and two positioning rings 39. The sliding base 34 is fixedly connected to the drive motor 31 and slidably connected to the fixed base 1. The gear sleeve 35 is fixedly connected to the drive gear 33 and is sleeved on the drive shaft 32. The gear sleeve 35 can slide up and down along the axial direction of the drive shaft 32 and can rotate synchronously with the drive shaft 32. The shift pin 36 is movably connected to the gear sleeve 35 and can slide circumferentially along the gear sleeve 35. The middle position of the shift lever 37 is rotatably connected to the sliding base 34 via a third hinge shaft 341. One end of the shift lever 37 is provided with a first groove 371 for accommodating the shift pin 36, and the other end is provided with a second groove 372. One end of the positioning rod 38 is vertically fixed to the sliding base 34, and the other end extends out from the second groove 372. Two positioning rings 39 are fitted and threaded onto the positioning rod 38. The two positioning rings 39 are located on both sides of the shift lever 37 and are used to fix the shift lever 37.

[0039] When it is necessary to switch the position of the drive gear 33, the positioning ring 39 is turned so that the shift lever 37 can rotate around the third hinge shaft 341, causing the first slide groove to move up and down in the vertical direction. This allows the drive gear 33 to switch between the first and second positions through the shift pin 36 and the gear sleeve 35, so that it can be selected to mesh with the transmission gear 42 or with the rotary gear 22.

[0040] There are many ways to connect the shifting pin 36 and the gear sleeve 35, such as... Figure 4 As shown, this can be achieved by setting a third groove 351 on the gear sleeve 35, or by setting a collar on the shifting pin 36 and setting a corresponding receiving structure on the gear sleeve 35. These are all existing technologies and will not be described in detail here.

[0041] There are many ways to achieve a sliding connection and synchronous rotation between the gear sleeve 35 and the drive shaft 32. It can be achieved through the combination of a single key and a keyway, or through a spline connection. Alternatively, a limiting plane can be machined on the drive shaft 32, and a corresponding locking block can be set on the gear sleeve 35. The synchronous rotation of the two can be achieved through the cooperation of the locking block and the limiting plane. These are all existing technologies and will not be elaborated here.

[0042] The methods for changing the position of drive gear 33 are not limited to Figure 4 The structure shown can also omit the shift lever 37, positioning lever 38 and positioning ring 39, and directly switch the position of the drive gear 3 by manually moving the shift pin 36.

[0043] Furthermore, in the embodiments of this application, such as Figure 4As shown, a ball bearing 320 can also be provided between the sliding base 34 and the fixed base 1 to change the sliding friction between the sliding base 34 and the fixed base 1 to rolling friction, thereby reducing the friction between the sliding base 34 and the fixed base 1.

[0044] Specifically, in the embodiments of this application, such as Figure 3 As shown, a sliding cover 11 can also be movably connected to the fixed base 1. The sliding cover 11 has a first through hole 111, a second through hole 112, and a third through hole 113. The sliding cover 11 covers the drive mechanism 3. The fixed column 21 extends out from the first through hole 111, the drive shaft 32 extends out from the second through hole 112, and the transmission column 41 extends out from the third through hole 113. A wedge block 114 is also provided on the sliding cover 11. The fixed base 1 has a cover guide groove 12 with the fixed column 21 as the center. The wedge block 114 is accommodated in the cover guide groove 12 and can slide along the cover guide groove 12. The sliding cover 11 can protect the drive mechanism 3, preventing the drive gear 33, rotary gear 22, and transmission gear 42 from being damaged by foreign objects or from increased wear due to dust, etc. At the same time, it can provide additional support for the drive shaft 32 and the transmission column 41, improving the stress state.

[0045] Furthermore, a motor guide groove 13 is annularly arranged on the fixed base 1 with the fixed column 21 as the center. The drive motor 31 is housed in the motor guide groove 13 and can slide along the motor guide groove 13. When performing the rotation action, the drive gear 33 meshes with the rotation gear 22, the drive motor 31 slides along the motor guide groove 13, and drives the sliding base 34 to slide synchronously, thereby driving the lifting mechanism 4 and the gripping mechanism 5 to perform the rotation action.

[0046] Furthermore, a cover plate 115 can be provided on the sliding cover 11 to cover the motor guide groove 13 and prevent foreign objects from entering the motor guide groove 13 and affecting the movement of the drive motor 31.

[0047] Finally, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this application, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0048] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0049] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
