[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0029] The first embodiment of the present invention provides an electric stainless steel lining material transport device. Figure 1-2 , which includes a driving unit, which allows construction workers to drive the transport device to distribute stainless steel lining materials after they are in place. The driving unit has a frame 12, which can be a rectangular flat structure. The front and rear of the frame are provided with multiple sets of passive wheels 13 ( Figure 1 The right end is defined as the front of the frame, and the left end is defined as the rear of the frame). Figure 1 It can be seen that two groups of passive wheels are provided at the front end of the frame, and two groups are provided at the rear end of the frame. A group of driving wheels 3 is provided on the frame near the front passive wheels. The driving wheels are connected to the drive system. This case adopts an electric drive system, and the driving wheels and the front passive wheels can be synchronously installed with a steering system to facilitate fine-tuning of the forward direction inside the pipeline. The electric drive system and the steering system belong to the existing technology and will not be described in detail here.

[0030] The electric stainless steel lining material transport device also includes a material transport unit, which has a tube carrier 8. The tube carrier 8 can be a rectangular flat plate structure. One end of the tube carrier is provided with a first connection port 7 connected to the driving unit, and the other end is provided with a moving wheel 9. The frame is provided with a second connection port 14 that cooperates with the first connection port. The first connection port and the second connection port can be connected by bolts. In this case, corresponding bolt holes can be provided on the first connection port and the second connection respectively. In this case, the first connection port is provided with a first upper guide tongue 7a and a first lower guide tongue 7b parallel to each other, and the second connection port is provided with a second upper guide tongue 14a and a second lower guide tongue 14b parallel to each other. During installation, see Figure 3 , the first lower guide tongue 7b is inserted into the gap between the second upper guide tongue 14a and the second lower guide tongue 14b, and the gap between the first upper guide tongue 7a and the first lower guide tongue 7b is just enough to allow the second upper guide tongue 14a to be in place. At this time, the bolt P is inserted into the tongue-type docking mechanism to realize the docking of the material transport unit and the driving unit.

[0031] The tube carrier is equipped with a first jack 6 and a second jack 10. Both jacks can be fixed to the tube carrier via respective bases, for example, by welding or bolting. The tube carrier near the first connection port is equipped with the first jack 6, while the tube carrier near the moving wheel is equipped with the second jack 10. The tube carrier between the first and second jacks defines a tube placement space 11.

[0032] The tube blank carrier is provided with a tube blank anti-skid device 15, which is distributed close to the first jack 6, and the tube blank anti-skid device 15 adopts a block structure with a triangular cross-section. After the round tube blank is placed in the tube blank placement space, the tube blank anti-skid device 15 can be used to place the tube blank and move it left and right, thereby minimizing the possibility of large-scale movement of the tube blank. After the tube blank is in place, the two jacks support the tube blank by lifting and lowering.

[0033] In this embodiment, the size of the transport device needs to be adapted to the size of the stainless steel lined installation pipe, such as the pipe carrier, the frame, etc.

[0034] from Figure 1 It can be seen that a vertically distributed lighting device 4 is provided at the front of the vehicle frame to facilitate normal operation in a dark environment during municipal construction.

[0035] An anti-rotation mechanism can be set between the first connection port and the second connection port of the frame. For example, two polygonal longitudinal holes are set in the tongue-type docking mechanism, and polygonal locking rods are installed in the polygonal longitudinal holes to reduce the problem of rotation around the locking bolts between the tube carrier and the driving unit. Of course, when two or more bolts P are set between the tube carrier and the driving unit, the anti-rotation mechanism can be ignored.

[0036] exist Figure 1 In the embodiment, a battery unit 5 serving as a first counterweight is provided at one end of the frame, and a driving position 1 serving as a second counterweight when the driver is in position is provided at the other end. A driving handle 2 for controlling the vehicle is provided at the driving position.

[0037] The working mode of the utility model is as follows:

[0038] 1. Stainless steel tube processing (specific size and weight are set according to actual conditions):

[0039] -Use a plate rolling machine to round the stainless steel plate to produce a standard length of 1.5m.

[0040] -The diameter of the tube blank is controlled within 600mm to adapt to the inner diameter of most pipes.

[0041] - After passing the quality inspection, it will be transported to the construction site.

[0042] - Make tube billets in the tube billet prefabrication area, and transport them to the site in batches to ensure sufficient stainless steel tube billets are available on site.

[0043] 2.Transportation and fixation of tube blanks:

[0044] -After the pipe is rolled, the billet is hoisted into the operating pit.

[0045] -Use electric transport trolley to deliver the pipe blank into the original pipeline.

[0046] - Transport the lining section by section through the working pit to achieve continuous operation. (An additional installer is required to be responsible for the actual lining installation work, including positioning and fixing the lining.)

[0047] 3. Stainless steel lining installation:

[0048] -Adopt a phased and concentrated operation approach.

[0049] -First complete the pipe layout and spot welding of pipe blanks over 100m long.

[0050] -Then proceed with welding the longitudinal and circumferential seams. (During construction, the stainless steel tube billet is fed from one end and spot welded at the other end. While welding the already laid stainless steel liner pipe, the next section of pipe is laid.)

[0051] 4.Welding requirements:

[0052] -Strictly abide by GB50236-2011 national standard.

[0053] -Welders must wear complete personal protective equipment, including welding masks, protective clothing, gloves, etc.

[0054] - Clean the welding area thoroughly before welding.

[0055] - Position and expand each section of pipe (after reducing the diameter) in the pipeline so that the stainless steel lining fits tightly against the original old pipe.

[0056] -Use high purity (≥99.9%) argon gas for argon arc welding, with each section of pipe overlapped by about 4mm.

[0057] -Use stainless steel special tools throughout the process to avoid contact with iron ions (during the entire processing and manufacturing process of the inner liner, it is necessary to strictly prevent contact with iron ions, which will affect the corrosion resistance of the stainless steel liner).

[0058] The second embodiment of the present invention provides an electric stainless steel lining material transport device. The difference between this embodiment and the first embodiment is that two tube blank anti-slip devices are provided.

[0059] This embodiment also includes a driving unit, which can be equipped with an electric drive system and a corresponding steering structure. The tube carrier is provided with a first jack 6 and a second jack 10. The tube carrier near the first connection port is provided with the first jack 6, and the tube carrier near the moving wheel is provided with the second jack 10. The tube carrier between the first jack and the second jack has a tube placement space 11. In this case, the tube carrier is provided with two tube anti-slip devices, such as Figure 4 The two wedge blocks shown are placed in the tube blank placement space 11. The two wedge blocks here can be made of wood blocks or rubber blocks. The appearance of the two tube blank anti-slip devices can improve the installation stability of the tube blank.

[0060] The third embodiment of the present invention provides an electric stainless steel lining material transport device. The difference between this embodiment and the first embodiment is that the tube carrier is provided with a tube anti-slip device guide fixing mechanism, such as a T-shaped guide fixing block. Figure 5 A T-shaped guide fixing block is provided on the surface of the tube carrier 8. The T-shaped guide fixing block 16 (distributed along the width direction of the tube carrier, and can be arranged throughout the body or a plurality of intermittently distributed T-shaped guide fixing blocks can be coaxially distributed) cooperates with the tube anti-slip device with a triangular cross-section (the tube anti-slip device is provided with a T-shaped groove structure). During installation, the T-shaped groove structure of the tube anti-slip device is aligned with the T-shaped guide fixing block and then fixed in place. This can ensure that the tube anti-slip device does not move along the length direction of the tube carrier, and more importantly, it avoids the safety accident caused by the rolling of the circular stainless steel lining due to the slip of the tube anti-slip device.

[0061] Of course, a carbon monoxide detection sensor and a temperature sensor can be installed at the bottom of the tube carrier. The above-mentioned carbon monoxide detection sensor and temperature sensor are connected to the controller, and the controller is connected to the alarm installed in the driver's seat. When indicators such as carbon monoxide inside the working pipeline are abnormal, the operator can be warned in time.

[0062] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
