Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline construction auxiliary tooling, and specifically provides a socket-and-spigot type concrete pipeline installation butt joint device. BACKGROUND

[0002] The socket-and-spigot type concrete pipeline is a prefabricated concrete pipeline adopting socket and spigot cooperation, and the two ends of the pipeline are a socket and a spigot respectively, and generally the spigot of one pipeline is inserted into the socket of another pipeline to complete butt joint; in the existing pipeline butt joint construction process, the pipeline needs to be hoisted by hoisting equipment (excavators can be temporarily used as movable hoisting machinery), and the lifting device is mostly a lifting rope directly sleeved on the outside of the pipeline; in the process of hoisting movement, two or more workers need to hold the pipeline to ensure the stability of the pipeline, and when the workers do not cooperate properly, the pipeline is prone to tilt and slide off the lifting rope, which poses a threat to the safety of the workers; when the pipeline moves close to another pipeline, manual cooperation is still needed to adjust the position of the pipeline so that the spigot of the hoisted pipeline is aligned with the socket of the laid pipeline as much as possible, and under the movement of the hoisting equipment, the pipeline completes butt joint insertion, but at this time, it is not in a completely inserted state, and the spigot end of the newly inserted pipeline is not in tight contact with the inner end face of the socket of another pipeline, so the pipeline needs to be further pushed in, and in most cases, the excavator is directly used to push the pipeline in, and at this time, the overlap segment of the two pipelines at the butt joint is relatively short, and the pipeline is more prone to tilt downward under the action of gravity, and when the pipeline is not effectively supported, direct pushing by the excavator increases the risk of structural damage and sealing failure of the pipeline at the butt joint, in addition, some use a tensioning device to tightly fit the two pipelines by tension, but during construction, the position of the tensioning device needs to be adjusted constantly as the pipeline is laid, and the tensioning device needs to be fixed again, which is relatively troublesome.

[0003] In summary, in the existing construction, during the entire hoisting and butt joint process of the pipeline, multiple manpower is needed to hold the pipeline, and manual adjustment of the butt joint posture of the pipeline is needed, which poses a great safety hazard during hoisting, and the butt joint accuracy depends on manual operation, in addition, after the pipeline is initially inserted, an external device is needed to tightly push the two pipelines, which affects the continuity and dependence of the construction operation.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 As shown, the socket-type concrete spigot pipe 5 is a precast concrete spigot pipe 5 using a socket 51 and a spigot 52. The two ends of the spigot pipe 5 are a socket 51 and a spigot 52, respectively. The socket 51 is usually flared to ensure the strength of the socket 51. The outer diameter of the spigot 52 is generally slightly smaller than the inner diameter of the socket 51. During the butt joint installation, the spigot 52 of the spigot pipe 5 to be connected is usually inserted into the socket 51 of the already laid spigot pipe 5. The socket 51 and the spigot 52 are sealed by a rubber ring 53. The socket 51 usually has a limiting groove pre-made to allow the rubber ring 53 to fall into the limiting position.

[0030] As shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the bottom end of the hoisting beam 1 is assembled with a self-adaptive lifting frame 2, and the bottom end of the hoisting beam plate 12 is welded with a horizontal moving guide base 13; the self-adaptive lifting frame 2 comprises a horizontal moving plate 21 horizontally and slidingly installed on the horizontal moving guide base 13, the bottom end of the horizontal moving plate 21 is vertically welded with a plurality of guide rods 211, the plurality of guide rods 211 are uniformly distributed along a straight line perpendicular to the sliding direction of the horizontal moving plate 21, a lifting frame 22 is commonly and slidingly installed on the plurality of guide rods 211, the lifting frame 22 is a rectangular frame structure with a closed bottom end, the guide rods 211 and the bottom plate of the lifting frame 22 are in sliding fit, a first spring 23 is sleeved on each of the guide rods 211, and the two ends of the first spring 23 are welded on the bottom end of the horizontal moving plate 21 and the upper end face of the bottom plate of the lifting frame 22 respectively; the horizontal moving guide base 13 is provided with spring sheets 24 on the two side walls in the guide direction and fixed by bolts, and the spring sheets 24 are made of spring steel; the two spring sheets 24 are symmetrically distributed on the two sides of the horizontal moving plate 21, and the lifting frame 22 is located between the two spring sheets 24, two horizontally and oppositely arranged sliding rails 221 are welded on the side walls of the lifting frame 22 facing the two spring sheets 24, the lower end of the spring sheet 24 is horizontally welded with a sliding strip 241, the sliding strip 241 is vertically and slidingly installed between the two sliding rails 221, and the spring sheet 24 does not affect the vertical sliding of the lifting frame 22; the top end of the lifting frame 22 is welded with two side edge strips 222 protruding from the opposite side walls, the two side edge strips 222 are correspondingly arranged with the two spring sheets 24, and when the first spring 23 is broken due to an accident, the side edge strips 222 can block the sliding strip 241 to provide safety buffer protection.

[0031] As shown in Figure 1 , Figure 2 , Figure 3 ,Figure 4 and Figure 7 As shown in the figure, the lifting frame 22 is welded with a downward vertically extending overhang plate 25 at one end. The inner bracket 3 is assembled on the overhang plate 25 and is located below the lifting frame 22; the inner bracket 3 comprises an inner bracket assembly horizontally extending into the socket pipe 5 and a push plate assembly 35 cooperating with the overhang plate 25 to push the socket pipe 5; the inner bracket assembly comprises a middle roller bracket 31 horizontally welded on the overhang plate 25, the middle roller bracket 31 is horizontally welded with three guide sleeves 311 uniformly arranged along the distribution direction of the guide rod 211, the guide sleeves 311 are axially arranged perpendicular to the distribution direction of the three guide sleeves 311; the middle roller bracket 31 is horizontally and symmetrically distributed with two side roller brackets 32, the two side roller brackets 32 are each welded with three guide columns 321 slidingly fitted with the three guide sleeves 311, and the two side roller brackets 32 and the middle roller bracket 31 are each horizontally welded with two No. 33 springs, the two No. 33 springs and the three guide sleeves 311 are uniformly and alternately distributed in the same straight line direction; the middle roller bracket 31 and the two side roller brackets 32 are each horizontally rotatably installed with a roller 34.

[0032] When the socket pipe 5 is hoisted, the inner bracket assembly will extend into the pipe from one end of the socket 51 of the socket pipe 5, and the socket pipe 5 will fall on the three rollers 34, the force of the two rollers 34 located on the side roller brackets 32 on the socket pipe 5 can be decomposed into a vertically upward supporting force and a horizontally inward supporting force, the No. 33 spring will be self-adaptively contracted, under the common support of the three rollers 34, the rollers 34 on the two sides will be tightly supported on the inner wall of the socket pipe 5, improving the stability of the socket pipe 5 hoisted and supported.

[0033] As shown in the figure, the lifting frame 22 is welded with a downward vertically extending overhang plate 25 at one end. The inner bracket 3 is assembled on the overhang plate 25 and is located below the lifting frame 22; the inner bracket 3 comprises an inner bracket assembly horizontally extending into the socket pipe 5 and a push plate assembly 35 cooperating with the overhang plate 25 to push the socket pipe 5; the inner bracket assembly comprises a middle roller bracket 31 horizontally welded on the overhang plate 25, the middle roller bracket 31 is horizontally welded with three guide sleeves 311 uniformly arranged along the distribution direction of the guide rod 211, the guide sleeves 311 are axially arranged perpendicular to the distribution direction of the three guide sleeves 311; the middle roller bracket 31 is horizontally and symmetrically distributed with two side roller brackets 32, the two side roller brackets 32 are each welded with three guide columns 321 slidingly fitted with the three guide sleeves 311, and the two side roller brackets 32 and the middle roller bracket 31 are each horizontally welded with two No. 33 springs, the two No. 33 springs and the three guide sleeves 311 are uniformly and alternately distributed in the same straight line direction; the middle roller bracket 31 and the two side roller brackets 32 are each horizontally rotatably installed with a roller 34. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the push plate assembly 35 includes two horizontally symmetrical push plates 352 arranged on both sides of the overhanging plate 25, and the two push plates 352 are respectively welded on the two side roller frames 32, and the push plates 352 move synchronously with the side roller frames 32; the sliding block 351 is vertically slidably installed on the overhanging plate 25, and the sliding block 351 is hingedly connected with the two push plates 352; the two push plates 352 are aligned with the plate surface of the overhanging plate 25 on the side facing the inner support assembly. When the inner support assembly is inserted into the socket pipe 5, the push plate 352 and the overhanging plate 25 can be attached to the end of the socket 51, so that the socket pipe 5 is further kept in a horizontal state and avoids tilting to one side. During the construction process, the two push plates 352 and the overhanging plate 25 form a triangular layout, which can be used together to push the socket pipe 5. The inner support assembly has the structural characteristics of a cantilever beam, and the push plate assembly 35 improves the structural strength of the inner support assembly. In addition, the sliding block 351 is centrally arranged, the two push plates 352 are connected with the sliding block 351 through the connecting rods 353, and the balance of the force of the two side rollers 34 is further ensured through the structural restriction, thereby enhancing the transmission and dispersion of stress between the structures.

[0034] During hoisting, the inner support of the socket pipe 5 in the pipe and the inner support clamping are realized by the inner support frame 3, which improves the stability of hoisting and solves the problem of tilting and falling during hoisting by hoisting ropes, thereby liberating manpower and avoiding the risk of hoisting. In addition, in the present application, the socket pipe 5 is fixed on the inner support frame 3, and can move synchronously with the inner support frame 3, the overhanging plate 25 and the lifting frame 22. The lifting frame 22 and the transverse plate 21 are vertically slidably connected through the guide rod 211, and are connected through the first spring 23. When the hoisting equipment keeps the height unchanged, the socket pipe 5 after hoisting still has a certain degree of freedom in the vertical direction. It should be noted that the actual load of the first spring 23 during hoisting of the socket pipe 5 is within the range of the load that can be borne, and the actual deformation is less than the maximum allowable deformation. In general, the corresponding spring can be reasonably selected by the person skilled in the art to ensure that the strength of the spring meets the actual demand. In addition, the transverse plate 21 moves along the transverse guide 13, and the spring sheet 24 is symmetrically installed between the transverse guide 13 and the lifting frame 22. Therefore, the socket pipe 5 also has a certain degree of freedom in the horizontal diameter direction.

[0035] As Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9As shown, in order to replace the manual implementation of the automatic alignment operation between the two socket pipes 5, the hanging beam 1 is also provided with a alignment mechanism 4, the alignment mechanism 4 comprises a hydraulic cylinder 41 horizontally fixed on the top end of the hanging beam plate 12 through a fixed seat, the hydraulic cylinder 41 is an existing electric hydraulic cylinder, and the output rod of the hydraulic cylinder 41 penetrates through the lifting head 11; The translation frame 42 is horizontally and slidingly installed on the hanging beam 1, and the translation frame 42 and the transverse moving plate 21 are vertically and slidingly arranged opposite to each other; The lifting frame 43 is vertically and slidingly installed on the translation frame 42; The two side guide plates 14 are symmetrically welded on the hanging beam plate 12 at the two side ends in the guide of the transverse guide seat 13, and the two side guide plates 14 are provided with moving guide holes 141, the moving guide holes 141 comprise a horizontal section and an inclined section which is arc-shaped and connected with the horizontal section, the inclined section is arranged away from the overhanging plate 25 compared with the horizontal section, and the inclined section is inclined downward from the connection position with the horizontal section; The translation frame 42 comprises two sliding beams 421 which are slidingly and correspondingly installed on the side guide plates 14, and the string plate 423 is welded between the end portions of the two sliding beams 421 away from the overhanging plate 25, and the string plate 423 is fixed on the end portion of the output rod of the hydraulic cylinder 41 through bolts; The two sliding beams 421 are welded with guide plates 422 which are horizontally and symmetrically arranged; The lifting frame 43 comprises two lifting sliding plates 431 which are vertically and slidingly installed on the two guide plates 422, and a T-shaped plate 433 which is vertically and slidingly installed on the string plate 423, the hanging beam 1 is located between the two lifting sliding plates 431, the T-shaped plate 433 is welded with two horizontal shafts 434 which are arranged at the same height and the axial direction of which is parallel to the output direction of the hydraulic cylinder 41, and the two lifting sliding plates 431 are correspondingly and sleeved welded on the two horizontal shafts 434; The two lifting sliding plates 431 are fixed with moving pins 432 which move along the same side moving guide holes 141 through bolts. The two horizontal shafts 434 are provided with touch pressure clamping jaws 44 which are horizontally and symmetrically arranged; The touch pressure clamping jaw 44 comprises a fixed sleeve 441 which is fixed on the horizontal shaft 434 through bolts after sleeving, and the fixed sleeve 441 is vertically welded with two touch pressure arms 442 which are used for corresponding touch pressure with the two socket pipes 5. The bottom end of the touch pressure arm 442 is movably embedded with a plurality of rolling balls 443 which are used for contact with the socket pipe 5, and the plurality of rolling balls 443 are uniformly arranged along the axial direction of the fixed sleeve 441.

[0036] When the to-be-connected socket pipe 5 is hoisted by the inner bracket 3, the hoisting equipment drives the socket pipe 5 to move, so that the spigot 52 of the hoisted socket pipe 5 is roughly aligned with the socket 51 of the other socket pipe 5 (which can be automatically adjusted by the hoisting equipment or quickly adjusted by one construction worker), and the hoisted socket pipe 5 is slightly higher than the other socket pipe 5. Then, under the cooperation of the self-adaptive hanger 2, the automatic alignment between the two socket pipes 5 is realized through the alignment mechanism 4. Specifically, the hydraulic cylinder 41 is started, the sliding frame 42 is pushed to slide away from the overhanging plate 25, when the moving pin 432 moves along the horizontal section of the two moving guide holes 141, the lifting frame 43 moves horizontally synchronously with the sliding frame 42, so that the two touch pressure clamping jaws 44 move axially along the socket pipe 5, and the touch pressure arm 442 far away from the overhanging plate 25 among the touch pressure clamping jaws 44 can pass over the socket 51 of the laid socket pipe 5 (the socket 51 is trumpet-shaped and protrudes relative to the outer wall of the socket pipe 5), when the moving pin 432 moves along the inclined section of the moving guide hole 141, the lifting frame 43 continues to move horizontally while starting to gradually descend, because the to-be-connected socket pipe 5 is slightly higher, and the self-adaptive hanger 2 has a certain freedom in the vertical direction, therefore the two touch pressure arms 442 close to the overhanging plate 25 among the two touch pressure clamping jaws 44 will be clamped on the socket pipe 5 in advance, with the continuous output of the hydraulic cylinder 41, the two touch pressure arms 442 will push the to-be-connected socket pipe 5 to descend, during the descending process, one of the other two touch pressure arms 442 far away from the overhanging plate 25 will first contact the laid socket pipe 5, because the self-adaptive hanger 2 has a certain freedom in the horizontal linear direction of the socket pipe 5, and the laid socket pipe 5 has been fixed, therefore the hoisted socket pipe 5 is forced to move horizontally to align, when the other far touch pressure arm 442 contacts the laid socket pipe 5, the two touch pressure clamping jaws 44 are in a synchronous touch pressure clamping state for the two socket pipes 5, which can be defaulted as that the two socket pipes 5 are in a coaxial alignment state (the socket pipe 5 is a prefabricated concrete pipe formed according to the standard, and its manufacturing error can be ignored), then the automatic alignment between the two socket pipes 5 is completed through the alignment mechanism 4 without the need for multiple manual auxiliary alignment.

[0037] After the alignment, the step-by-step insertion and butt joint can be realized, at this time, the two touch pressure arms 442 in contact with the laid socket pipe 5 can roll along the outer wall of the pipe through the ball 443, the two touch pressure clamps 44 can be used as an insertion guide frame and take the laid socket pipe 5 as a guide fulcrum, and the device provided by the application is driven by the hoisting equipment to move towards the laid socket pipe 5, so that the suspended socket pipe 5 is pushed to the bottom step by step and inserted into another socket pipe 5 through the suspension plate 25 and the two push plates 352, so that the sockets 51 and the spigots 52 of the two socket pipes 5 are tightly connected. Through the auxiliary alignment and guide of the alignment mechanism 4 and the inner support frame 3, the insertion and butt joint of the two socket pipes 5 can be completed in one step, which is convenient to operate and high in efficiency, replaces the manual auxiliary alignment, preliminary insertion and butt joint and the construction mode of pushing and inserting by external equipment in the existing construction process, improves the automation degree of the butt joint operation and the continuity of the construction, improves the accuracy and construction quality of the butt joint, and reduces the structure damage and sealing failure of the socket pipe 5 at the butt joint.

[0038] After the insertion and butt joint is completed, the bottom of the inserted socket pipe 5 is supported and fixed in the state of being hoisted, then the hydraulic cylinder 41 is started again, the two touch pressure clamps 44 are retracted, then the lifting end of the hoisting equipment is lowered, the inner support frame 3 is lowered, the supporting roller 34 is separated from the inner wall of the socket pipe 5, finally the inner support assembly is pulled out from the socket pipe 5, and thus the whole operation of the butt joint of the single socket pipe 5 is completed.
