Description

Technical Field

[0001] The present application relates to the technical field of maintenance platforms, and in particular to a movable tunnel and pipeline maintenance platform. Background Art

[0002] Tunnel and pipeline inspection and maintenance platforms are multifunctional work platforms designed specifically for maintenance, inspection, and reinforcement work within tunnels and pipelines. These platforms are typically height-adjustable, mobile, and scalable to accommodate maintenance needs at different locations and heights.

[0003] When a certain location in a tunnel or pipeline is inspected through an inspection platform, it is necessary to move the construction platform to the next location after the inspection is completed to continue the inspection at the next location. However, it takes a long time to build the inspection platform again, and it is not as fast as building it in an open area. Therefore, it is more troublesome to move the inspection platform after building it in the tunnel and then inspecting the next inspection location. The existing inspection platform has a complex structure and a bulky size, which is not convenient for transportation and assembly, affecting the efficiency of rapid response and on-site deployment. Utility Model Content

[0004] In order to improve the efficiency of movement and deployment of the maintenance platform, the present application provides a movable tunnel and pipeline maintenance platform.

[0005] The present application provides a movable tunnel and pipeline maintenance platform adopting the following technical solutions:

[0006] A movable tunnel and pipeline maintenance platform includes a support frame and a scaffolding. The scaffolding is erected above the support frame. A positioning assembly for fixing the position of the scaffolding is provided on the support frame. Casters are provided below the support frame. A reel is provided on one side of the support frame. A winch is provided on the other side of the support frame.

[0007] By adopting the above technical solution, this mobile tunnel maintenance platform has excellent stability and convenience. The positioning components ensure the precise fixation of the scaffolding to the support frame, avoiding safety hazards caused by looseness. The installation of casters allows the platform to be easily moved to different working positions. The use of a winch to move the support frame also improves the efficiency of platform movement and deployment.

[0008] Optionally, the support frame includes a main beam and a secondary beam, and there are two main beams. The two main beams are arranged opposite to each other, and both ends of the two main beams are connected by secondary beams. The secondary beams and the main beams are fixed by angle steels. A triangular connecting plate is provided below the connection between the two secondary beams and the two main beams, and the casters are connected to the triangular connecting plate by bolts. A support beam is provided between the two main beams, and one end of the support beam is fixed to one of the main beams by a trapezoidal connecting plate, and the other end of the support beam is fixed to the other main beam by a trapezoidal connecting plate.

[0009] By adopting this technical solution, the support frame consists of a main beam and secondary beams, the connection between which ensures structural stability and strength. The use of angle steel further strengthens the connection points, and the triangular connecting plate design allows for the stable installation of casters, enhancing the mobility and stability of the entire platform. The arrangement of the support beams and their attachment to the main beams not only increases the overall rigidity of the platform but also distributes the load, improving its safety and load-bearing capacity.

[0010] Optionally, the positioning assembly includes a positioning cylinder, and the upright pole of the scaffold is inserted into the positioning cylinder and slidably engaged with the positioning cylinder.

[0011] By adopting the above technical solution, the positioning assembly uses the positioning cylinder to achieve stable support for the scaffolding uprights. The scaffolding uprights can be installed according to the position of the positioning cylinder while maintaining the stability and safety of the structure.

[0012] Optionally, the positioning assembly includes a positioning plate and a positioning block, the positioning block is arranged opposite to the positioning plate, a V-shaped clamping block is provided on the positioning block, and an adjusting member for adjusting the movement of the V-shaped clamping block is provided inside the positioning block.

[0013] By adopting this technical solution, when installing the scaffolding, the scaffolding uprights are first placed between the positioning plate and the positioning block. The adjusting member then drives the V-shaped clamping block to move and clamp the scaffolding, thus positioning and maintaining the stability of the structure. The use of a limit assembly to limit the position of the V-shaped clamping block and the scaffolding further enhances the reliability of the clamping.

[0014] Optionally, the adjusting member includes a pedal rod, which is rotatably connected to the positioning block, a gear ring is provided at one end of the pedal rod, a first rack is fixedly provided at the tail of the V-shaped clamping block, the first rack and the gear ring are engaged with each other, and a limiting component is provided on the positioning block to limit the movement of the V-shaped clamping block.

[0015] By adopting the above technical solution, the foot lever is rotatably connected to the positioning block. The operator can step on the foot lever, which drives the gear ring to rotate, thereby driving the movement of the rack and V-shaped clamping block, thereby conveniently and quickly positioning the scaffolding. This improves the reliability and safety of the scaffolding fixation.

[0016] Optionally, the limit assembly includes a limit rod, which is inserted into the positioning block and slides with the positioning block. A limit head is provided at the end of the limit rod, and a second rack is provided on the lower surface of the limit head. The second rack is engaged with the first rack.

[0017] By adopting this technical solution, the second rack meshes with the first rack, limiting the movement of the first rack and thus providing stable control of the scaffold. During use, the limit rod is pulled to disengage the second rack from the first rack. At this time, the foot lever can be used to control the clamping of the scaffold, ensuring that the scaffolding poles are firmly fixed in the positioning assembly, improving the safety and stability of the entire maintenance platform.

[0018] Optionally, a spring is sleeved on the limiting rod, one end of the spring is connected to the limiting head, and the other end of the spring is connected to the positioning block.

[0019] By adopting the above technical solution, under the action of gravity, the second rack and the first rack are engaged with each other. By setting a spring, the limit rod is prevented from moving easily under the action of external force, so that the second rack is separated from the first rack in advance, thereby improving the stability and reliability of the structure.

[0020] Optionally, the surfaces of the positioning plate and the V-shaped clamping block are both covered with rubber pads.

[0021] By adopting the above technical solution, the surfaces of the positioning plate and the V-shaped clamping block are covered with rubber pads, which can increase friction, improve the stability and safety of the scaffolding, and at the same time reduce wear on the scaffolding and extend the service life of the equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The precise fixation of the scaffolding on the support frame is ensured by installing support frames, casters, winches, and positioning cylinders, avoiding safety hazards caused by looseness. The installation of casters allows the platform to be easily moved to different working positions. At the same time, the use of winches to move the support frame improves the efficiency of platform movement and deployment.

[0024] 2. By installing a positioning plate, positioning block, V-shaped clamping block, and foot lever, the operator can step on the foot lever, which rotates the ring gear, thereby driving the movement of the rack and V-shaped clamping block, allowing for convenient and rapid positioning of the scaffolding. By installing a limit rod, limit head, and second rack, the scaffolding uprights are securely fixed within the positioning assembly, improving the safety and stability of the entire maintenance platform.

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The embodiments of the present application disclose a movable tunnel and pipeline maintenance platform.

[0032] Example 1

[0033] Reference Figure 1A movable tunnel and pipeline inspection platform includes a support frame 1 and a scaffold 3. The support frame 1 includes a main beam 101 and a secondary beam 102. Two main beams 101 are provided. The two main beams 101 are arranged opposite to each other, and both ends of the two main beams 101 are connected by secondary beams 102. The secondary beams 102 and the main beams 101 are fixed by angle steels 4. A triangular connecting plate 5 is provided on the lower surface of the connection between the two secondary beams 102 and the two main beams 101. Casters 6 are provided below the triangular connecting plate 5, and the casters 6 are connected to the triangular connecting plate 5 by bolts. A support beam 7 is provided between the two main beams 101. One end of the support beam 7 is fixed to one of the main beams 101 by a trapezoidal connecting plate 8, and the other end of the support beam 7 is fixed to the other main beam 101 by a trapezoidal connecting plate 8. The main beam 101, the secondary beam 102 and the support beam 7 are all U-shaped steel.

[0034] Reference Figure 1 and Figure 2 A connecting beam 9 is provided between the two main beams 101 on one side of a secondary beam 102. A drum 10 is provided on the connecting beam 9 and the adjacent secondary beam 102. A winch 11 is provided on the side near the drum 10. The winch 11 is connected to the drum 10 and moves the support frame 1, improving the efficiency of platform movement and deployment.

[0035] Reference Figure 1 and Figure 2 , a positioning assembly for fixing the position of the scaffolding 3 is provided on the support frame 1, and the positioning assembly includes a positioning cylinder 12. A plurality of positioning cylinders 12 are evenly provided on the main beam 101, the secondary beam 102 and the support beam 7. The uprights of the scaffolding 3 are inserted into the positioning cylinder 12 and slide in the positioning cylinder 12;

[0036] The scaffolding 3 can be adjusted in height according to the working environment of different tunnels through a buckle structure (not shown in the figure).

[0037] The implementation principle of a movable tunnel and pipeline inspection platform in the embodiment of the present application is as follows: the support frame 1 is composed of a main beam 101 and a secondary beam 102. The connection between the main beam 101 and the secondary beam 102 ensures the stability and strength of the structure. The use of angle steel 4 further enhances the firmness of the connection point, and the design of the triangular connecting plate 5 enables the casters 6 to be firmly installed, improving the mobility and stability of the entire platform. The provision of the support beam 7 and its fixing method to the main beam 101 not only increase the overall rigidity of the platform, but also disperse the load, thereby improving the safety and load-bearing capacity of the platform.

[0038] By inserting positioning tubes 12 into which the uprights of the scaffolding 3 are inserted, the scaffolding 3 is positioned and secured. A winch 11 is installed on one side of the support frame 1 and connected to a drum 10 on the support frame 1. To move the maintenance platform, operators simply activate the winch 11 to move the platform, eliminating the need for disassembly and reassembly of the entire platform, significantly improving work efficiency.

[0039] Example 2

[0040] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that the positioning assembly includes a positioning plate 13 and a positioning block 14. The positioning block 14 is arranged opposite to the positioning plate 13. A movable V-shaped clamping block 15 is provided on the side of the positioning block 14 close to the positioning plate 13. The surfaces of the positioning plate 13 and the V-shaped clamping block 15 are both covered with rubber pads (not shown in the figure), and an adjusting member for adjusting the movement of the V-shaped clamping block 15 is provided inside the positioning block 14.

[0041] Reference Figure 3 and Figure 4 The adjusting member includes a pedal rod 16, which is rotatably connected to the positioning block 14, and the rotating shaft is located at one end of the pedal rod 16. A gear ring 17 is provided at one end close to the rotating shaft of the foot rod 16, and a first rack 18 is fixedly provided at the tail of the V-shaped clamping block 15, and the first rack 18 is engaged with the gear ring 17.

[0042] Reference Figure 3 and Figure 4 The positioning block 14 is provided with a limit assembly that limits the movement of the V-shaped clamping block 15. The limit assembly includes a limit rod 19, which is sleeved with a spring 20. One end of the spring 20 is connected to a limit head 21, and the other end of the spring 20 is connected to the positioning block 14. The limit rod 19 is inserted into the positioning block 14 in the vertical direction and slides with the positioning block 14. The bottom of the limit rod 19 is provided with a limit head 21 above the first rack 18. The lower surface of the limit head 21 is provided with a second rack 22, which meshes with the first rack 18.

[0043] The implementation principle of Example 2 is as follows: When installing scaffolding 3, the bottom of the scaffolding 3 upright is first placed between the positioning plate 13 and the positioning block 14. The operator steps on the foot pedal 16 and simultaneously pulls the limiting rod 19, causing the second rack 22 to disengage from the first rack 18, thereby releasing the V-shaped clamping block 15. The ring gear 17 rotates, driving the first rack 18 to move, causing the V-shaped clamping block to clamp the scaffolding 3 upright. The limiting rod 19 is then released, and under the action of gravity and the elastic force of the spring 20, the first rack 18 re-engages with the second rack 22, limiting the position of the V-shaped clamping block 15. This ensures that the scaffolding 3 upright is securely fixed within the positioning assembly, improving the safety and stability of the entire maintenance platform.

[0044] To dismantle the scaffold 3, just pull the limit rod 19 and rotate the pedal rod 16 in the opposite direction to drive the first rack 18 back to its original position and release the scaffold 3. The operation is simple and the work and deployment efficiency is improved.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
