Technical Field

[0001] The utility model relates to the technical field of steel pipe transportation devices, in particular to a diameter-variable steel pipe transportation auxiliary device. Background Art

[0002] During the construction of infrastructure such as urban water supply and sewage treatment, the construction environment is often complex, especially during the pipeline laying stage. When the pipeline needs to pass through narrow streets or areas with dense cables above it, traditional transport vehicles and lifting equipment are unable to directly deliver the pipes to the predetermined location due to space limitations, which brings great challenges to construction. Similarly, in the field of water conservancy and hydropower engineering, faced with deep foundation pit operations that need to be formed by slope excavation, the limited space at the bottom of the foundation pit is insufficient to support the normal operation of the crane; in addition, the distance from the foundation pit opening line to the center line of the pipeline is too large, which further limits the possibility of the crane directly transporting the pipeline, making the construction difficulty significantly increased. In addition, the existing conventional slide rail trolley system has significant limitations. They are usually only capable of transporting a single type of steel pipe. This singleness not only limits the flexibility of construction materials, but also greatly reduces the overall construction efficiency, and cannot meet the needs of modern and efficient construction.

[0019] like Figure 1-6As shown, the utility model provides a variable-diameter steel pipe transportation auxiliary device, including a track laid on a concrete layer of a bottom plate for pipe sheathing, and is characterized in that: a steel plate bracket 1 is slidably installed on the track, and walking steel wheels 3 adapted to the track are rotatably installed at both ends and the middle of the steel plate bracket 1, and winches are fixedly arranged at both ends of the track, and traction rings 2.3 for connecting the wire rope on the winch are provided at both ends of the steel plate bracket 1, and main brackets 1.1 are equidistantly arranged on the steel plate bracket 1 along the length direction, and a sub-bracket adapted to the outer diameter of the steel pipe is detachably installed on the main bracket 1.1, and arc grooves are provided on the tops of the main bracket 1.1 and the sub-bracket, and the inner diameter of the arc groove of the main bracket 1.1 is larger than the inner diameter of the arc groove of the sub-bracket.

[0020] The steel plate bracket 1 is a rectangular frame structure. The main bracket 1.1 and the auxiliary bracket are made of 20mm steel plates. Holes are opened at the ends of the main bracket 1.1 and the auxiliary bracket for the movable bolts 1.2 to pass through.

[0021] The steel plate bracket 1 is installed with main brackets 1.1 at equal intervals according to the length. In the figure, four main brackets 1.1 are installed, which can provide stable support for the steel pipe.

[0022] The transportation of steel pipes includes the following steps:

[0023] Step 1: Process and assemble the steel plate bracket 1, frame main beam 2 and walking steel wheel 3 according to the pipeline size determined by the design drawings and the actual situation on site.

[0024] Step 2: Lay the track according to the spacing of the walking steel wheels 3. Channel steel or I-beam can be used for the track. The track is usually arranged on the pipe-wrapped bottom plate concrete. The partially suspended parts can be reinforced with I-beams. The joints of the track are connected by welding. Rebars can be driven into the concrete on both sides of the track and welded to the track to fix the track, thereby ensuring that the trolley can run smoothly on the track.

[0025] Step 3: After track laying and acceptance, install the winch. The winch traction rope passes through the traction ring 2.3 and is connected to the steel pipe transportation auxiliary device.

[0026] Step 4: Hoist the steel pipe onto the steel plate bracket 1 and fix it, and use the winch to provide power to pull the steel pipe transportation auxiliary device to the predetermined installation position.

[0027] Step 5: Once the pipe transport assist device has reached its intended installation location, weld four lugs to the outer ends of the pipe using steel plates to serve as support points for the jack. Lift the pipe using the jack, remove the pipe transport assist device, and then lower the jack to allow the pipe to land. After the rails have been cut and removed, adjust the pipe's positioning.

[0028] like Figure 1-4As shown, the edge of the steel plate bracket 1 is provided with a frame main beam 2, which includes a cross beam 2.1 and a longitudinal beam 2.2. The main bracket 1.1 is fixed to the cross beam 2.1. The cross beam 2.1 is generally a 120mm×300mm×20mm steel plate, and the longitudinal beam 2.2 is made of square steel.

[0029] like Figure 1-4 As shown. The ends of the main bracket 1.1 and the auxiliary bracket are provided with corresponding connection holes for the movable bolts 1.2 to pass through. The connection holes at one end are arranged in a triangular pattern. The movable bolts 1.2 are threadedly connected to the crossbeam 2.1. The main bracket 1.1 is directly mounted on the crossbeam 2.1, and the auxiliary bracket can be further mounted on the main bracket 1.1. The auxiliary bracket has a smaller support range than the main bracket 1.1, so when using the auxiliary bracket for support, it will not be interfered with by the main bracket 1.1.

[0030] like Figure 4 The auxiliary brackets include a first auxiliary bracket 1.3, a second auxiliary bracket 1.4, and a third auxiliary bracket 1.5, each with its inner diameter decreasing in sequence. The three different types of auxiliary brackets, combined with the main bracket 1.1, can provide limited support for steel pipes of four sizes.

[0031] like Figure 1-4 As shown, the traveling steel wheel 3 is fixed to the bottom of the longitudinal beam 2.2 and comprises a steel wheel hub 3.1, a bearing 3.2, a mounting shaft 3.3, and a reinforcing steel plate 3.4. The reinforcing steel plate 3.4 is a channel steel with a notch at the bottom. The mounting shaft 3.3 is rotatably mounted within the reinforcing steel plate 3.4 via the bearing 3.2. The steel wheel hub 3.1 is fixed to the mounting shaft 3.3. The reinforcing steel plate 3.4 is directly mounted to the bottom of the longitudinal beam 2.2 and serves as the mounting frame for the steel wheel hub 3.1. The steel wheel hub 3.1 is fabricated from a φ100mm steel column cut and welded with a wheel attachment.

[0032] like Figure 5 As shown. An I-beam is welded to the bottom of the suspended portion of the track. Dowel bars are vertically fixed within the concrete layer on both sides of the track and welded to the track. For tracks constructed with I-beams, the bottom of the steel hub 3.1 is located within the cavity at the top of the track, fitting with the end walls of the hub 3.1 to limit its position.
