Description

Technical Field

[0001] This utility model belongs to the field of subway electromechanical water supply and drainage construction technology, specifically a multi-functional railcar for connecting and transporting pipelines in subway sections. Background Technology

[0002] Subway water supply, drainage, and fire protection systems are key components of urban rail transit, ensuring its safety and providing fire protection and flood prevention for the track system. The conventional construction process for water supply, drainage, and fire protection pipelines in urban rail transit sections requires the completion of trench construction by the track maintenance unit before the pipelines can be transported to the trench location. During construction, the pipeline clearances and elevations must be checked and verified, and then the pipelines are manually lifted onto supports for connection. This entire process is inefficient, time-consuming, and causes significant operational disruptions.

[0003] In some domestic subway sections, ductile iron pipes are used for water supply, drainage, and fire protection. Transporting and lifting a single pipe requires at least three people, and chain hoists and lifting slings are also needed for connection. Currently, water supply, drainage, and fire protection pipelines in subway sections are a necessary prerequisite for track laying, and construction time is short. However, the presence of multiple construction disciplines inevitably leads to cross-interference, requiring a significant amount of unnecessary and easily saved manpower. Furthermore, after the track is formed, rail welding vehicles are needed for on-site work. This construction method is fully enclosed, and other disciplines can only work during designated maintenance windows, requiring materials to be kept out of storage, further complicating the construction process. Summary of the Invention

[0004] To address the technical problems of significant operational interference, long construction cycles, and low work efficiency in the construction of existing subway water supply, drainage, and fire protection pipelines, this utility model provides a multi-functional railcar for connecting and transporting pipelines in subway sections.

[0005] This utility model adopts the following technical solution: a multi-functional railcar for connecting pipelines in subway sections, comprising:

[0006] A transfer railcar, used to carry and transfer pipelines;

[0007] A vertical support beam, which is fixed on the transport railcar;

[0008] A support beam, one end of which is hinged to the end of a vertical support beam, is equipped with a movable lifting guide chain wheel, and the other end of which is equipped with a lifting beam foot for contacting the tunnel wall.

[0009] A socket-connected pipe assembly, which is connected to a lifting guide sprocket by a chain and is used to install and connect pipes;

[0010] A construction clearance verification test component is installed on a transport railcar.

[0011] In some embodiments, the transport railcar includes:

[0012] Raise the chassis, and install rail wheels and matching axles on the raised chassis;

[0013] Anti-rollover baffles are symmetrically arranged on both sides of the raised frame.

[0014] In some embodiments, the support beam is provided with multiple positioning holes;

[0015] One end of the support beam is hinged to the end of the vertical support beam via a pin, and one end of the support beam is fixed to the diagonal brace, while the other end of the diagonal brace is connected to the vertical support beam.

[0016] A telescopic rod is inserted into the other end of the support beam. The telescopic rod is locked to the support beam by a positioning pin, and the end of the telescopic rod is hinged to the foot of the lifting beam.

[0017] In some embodiments, two sets of vertical support beams are provided, and both sets of vertical support beams are located on one side of the transport railcar.

[0018] In some embodiments, the socket connection pipe assembly includes:

[0019] Two locking rings, which can be rotated relative to each other and locked, are hinged together by a hinge, and locking bolts are provided at the openings of the two locking rings for locking.

[0020] Two fixed ears are symmetrically fixed on two locking rings. The fixed ears are connected to the positioning holes, and a movable pulley is installed on the front side of each fixed ear.

[0021] In some embodiments, the construction clearance verification test component includes:

[0022] The upper limit of the longitudinal direction is used to calibrate the chrome-plated optical axis.

[0023] In some embodiments, the longitudinal upper limit calibration chrome-plated optical axis is mounted on one end of the transverse chrome-plated optical axis via a cross shaft block, and the other end of the transverse chrome-plated optical axis is fixed to a base mounted on a transport railcar.

[0024] In some embodiments, the base is made of magnets.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The subway system extensively uses ductile iron pipes for water supply, drainage, and fire protection. Transporting and lifting a single pipe requires at least four people, and also necessitates the use of hand-operated hoists and lifting slings for connection. Using this invention can reduce the number of personnel needed for transport, decrease worker workload, and reduce physical injuries caused by manual labor.

[0027] Currently, water supply, drainage, and fire protection pipelines in subway sections are necessary prerequisites for track completion, and construction time is short. After the track is formed, rail welding vehicles are required for on-site work. This construction method is fully enclosed, and other disciplines can only carry out their work during designated maintenance windows, inevitably causing cross-interference due to the large number of disciplines involved. This invention integrates several processes into one work group, shortening construction time and reducing interference from other units.

[0028] The construction of trackside ditches is time-consuming, and traditionally, materials cannot be stored during this stage, leading to widespread idle time and further complicating construction. This new utility model features highly integrated tools and equipment, facilitating the completion and depletion of materials as required by track maintenance units during track maintenance windows. It allows for simultaneous installation and transport of pipelines, enabling immediate installation and testing, with tools and equipment carried on the train. This not only significantly improves efficiency during new line construction but also offers advantages in the construction and renovation of existing line water supply, drainage, and fire protection pipelines.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] like Figure 1 As shown, a multi-functional railcar for connecting pipelines in subway sections includes:

[0037] A transfer railcar, used to carry and transfer pipelines;

[0038] Vertical support beam 2, which is fixed on the transport railcar;

[0039] Support beam 6, one end of which is hinged to the end of vertical support beam 2, and a movable lifting guide chain wheel 11 is provided on support beam 6. Lifting beam foot 9 is installed on the other end of support beam 6 for contacting the tunnel wall.

[0040] A socket-connected pipe assembly, which is connected to the hoisting guide sprocket 11 by an iron chain, is used to install and connect pipes;

[0041] A construction clearance verification test component is installed on a transport railcar.

[0042] The transport railcar includes:

[0043] Raise the frame 3, and install rail wheels and matching axles 1 on the raised frame 3;

[0044] Anti-rollover baffles 4 are symmetrically arranged on both sides of the lifting frame 3.

[0045] Specifically, the frame is constructed by welding angle steel together. The frame and wheel axles utilize a raised frame 3 to reduce the height difference between the transported pipeline and the railcar. Two sets of support beams 2 are welded diagonally onto the frame, with pin holes pre-drilled at the top for connecting the vertical support beams 2. An anti-rollover baffle 4 is installed on the raised frame 3 to prevent the pipeline from tipping over and causing the vehicle to overturn. During use, the pipeline is first hoisted onto the transport railcar in a lifting environment, and then pushed to the specific construction location.

[0046] There are two sets of vertical support beams 2, and both sets of vertical support beams 2 are located on one side of the transport railcar.

[0047] As shown in the figure, multiple positioning holes are provided on the support beam 6;

[0048] One end of the support beam 6 is hinged to the end of the vertical support beam 2 via a pin, and the support beam 6 is fixed to one end of the diagonal brace 7, while the other end of the diagonal brace 7 is connected to the vertical support beam 2.

[0049] The other end of the support beam 6 is connected to a telescopic rod, which is locked to the support beam 6 by a positioning pin 8, and the end of the telescopic rod is hinged to the lifting beam foot 9.

[0050] When using the support beam 6, pull out the positioning pin 8 to adjust its length, and extend the support beam 6 to the position of the tunnel wall. Use the lifting beam foot 9, which can be adaptively adjusted according to the tunnel slope. The bottom plate of the lifting beam foot 9 should be as flat as possible against the curved tunnel wall. Laterally move the lowered lifting chain hoist wheel 10 onto the vehicle, load both ends of the pipe onto the two sets of lifting guide chain wheels 11, fix them, and laterally move the pipe to the top of the support. Then, release the chain hoist.

[0051] The socket connection pipe assembly includes:

[0052] Two locking rings 13, which can be rotated relative to each other and locked. The two locking rings 13 are hinged by a hinge 12, and locking bolts 14 are provided at the openings of the two locking rings 13 for locking.

[0053] Two fixed ears 15 are symmetrically fixed on two locking rings 13. The fixed ears 15 are connected to the positioning holes. A movable pulley 16 is installed on the front side of each fixed ear 15.

[0054] Specifically, a hinge 12 connects two rotatable locking rings 13, and two locking bolts 14 are provided for insertion and tightening to lock the pipes. Fixing ears 15 are provided on both sides, and U-shaped rings are welded to the fixing ears 15, through which two movable pulleys 16 are inserted. A matching chain is used to fix the other end to the support beam 6, and the pulleys 16 allow the matching chain to slide. When not in operation, the fixing ears 15 are connected to the positioning holes on the support beam 6 via pins, and the socket-connected pipe assembly is fixed to the support beam 6. During operation, the pins are opened, the socket-connected pipe assembly is removed from the support beam 6, and the locking rings 13 are used to secure the pipe.

[0055] The construction clearance verification test assembly includes: a longitudinal upper limit calibration chrome-plated optical axis 20. The longitudinal upper limit calibration chrome-plated optical axis 20 is mounted on one end of a transverse chrome-plated optical axis 18 via a cross axle block 19, and the other end of the transverse chrome-plated optical axis 18 is fixed to a base 17 mounted on a transport railcar. The base 17 is made of magnets.

[0056] Fix the base 17 to the front of the transport railcar. Adjust the cross slider 19 according to the length and width limit requirements of the drawing until the width and height meet the limit requirements of the drawing. Tighten the locking knob. The horizontal chrome-plated optical axis 18 will no longer slide. Push the transport railcar and observe whether any obstacles hit the optical axis. Then you can observe whether the bracket exceeds the limit.

[0057] The system's supporting construction methods can integrate transportation, hoisting into place, socket connection, and clearance verification testing into simultaneous operations by the same work team.

[0058] 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.
