Description

Technical Field

[0001] The present invention relates to the field of engineering construction equipment, and in particular to a slope transportation device and method. Background Art

[0002] In water conservancy and hydropower projects, penstocks are used to transport water from reservoirs, forebays, or surge tanks to turbines. When installing penstocks during hydropower station construction, welded sections must be transported or hoisted for easy installation.

[0003] Due to varying construction site conditions, steel pipes may be installed in flat or inclined sections, using either exposed or buried pipe installation methods. Exposed pipe installation is easier due to its unrestricted space, and currently, installation can be accomplished using either trolley transport or crane lifting in most cases. However, buried pipe installation is currently more commonly used because steel pipes are almost always located in narrow tunnels, where space is limited. When installing buried pipes in inclined shafts or on slopes, winches are currently the most common method for traction.

[0004] The Chinese patent application number 202110670607.0 discloses a method for transporting steel pipes in inclined shafts, which uses three sets of winches to provide traction. By welding rollers on the steel pipes, the steel pipe body is used as a transport trolley, and the steel pipe is installed after being transported along the track. This type of transportation and installation method is more suitable for pipe sections with regular cross-sections or shorter lengths. Due to its certain limitations, it is difficult to use for some pipe sections with support rings, pipe sections with longer single sections, pipe sections with larger tonnage, or pipe sections with higher installation heights. In addition, this solution also requires the removal of the rollers welded on the body later, which is more cumbersome. In addition, when using this method to transport steel pipes, the traction point must be set on the steel pipe, and the lifting lugs must be welded on the stiffening ring of the steel pipe to be towed or on the pipe wall to fix the traction wire rope. The preparation work is large, and the quality of the lifting lug welding is difficult to control, which can easily lead to safety accidents. Summary of the Invention

After the steel pipe is lowered into place, the rollers on both sides of the trolley rise and adhere to the outer wall of the steel pipe, loosen the steel wire ropes fixing the steel pipe and the connecting frame, and then control the rollers to continue to rise to lift the steel pipe to the installation height. At the same time, the lifting support on the trolley rises and falls synchronously to limit the position of the steel pipe during the lifting process.

[0051] The roller is used to adjust the left and right angles of the steel pipe so that it can be aligned and installed. The end of the steel pipe segment is then welded together with the already installed steel pipe segment. After the welding is completed, a temporary support is set at the front end of the steel pipe segment.

[0052] After the temporary support is installed, the lifting support and the roller fall back.

[0053] By adopting the steel pipe installation method described in the present invention, the steel pipe is lifted by the roller, and the lifting support is lifted synchronously to limit the steel pipe during the lifting process. After the steel pipe section is welded and connected and a temporary support is installed, the lifting support and the roller can fall back, which can facilitate the retraction of the trolley and solve the problem of difficulty in retracting the trolley due to the support ring protrusion of the steel pipe section. The steel pipe installation method has simple steps, easy operation and good effect.

[0095] like Figures 1 to 12As shown, the slope transportation and installation method of steel pipes described in the present invention utilizes the slope transportation device described in Example 1, and the method includes the following steps:

[0096] S1. According to the track gauge of the trolley 200, the track 105 is laid on the ground to ensure that the two rails are parallel and the track gauge matches the trolley 200. In order to avoid the traction rope 102 from rubbing against the ground at the bend section where the flat section of the track 105 transitions to the inclined section, after the track 105 is installed, the rollers 106 are laid between the two rails at the bend section. The number and spacing of the rollers 106 can be adjusted according to the length of the bend section, the angle of the inclined surface, etc.

[0097] S2. Pre-dig a pre-buried pit for the jack limit component 104 at a suitable position on the upper flat section of the ground, bury the pre-welded jack limit component 104 in the pit and pour concrete, install the retractable wire component 101 at the end of the track 105, and fix it to the ground with bolts, anchors, etc. The retractable wire component 101 can rotate actively or passively, and can be reasonably selected according to different working conditions. One end of the traction rope 102 is connected to the retractable wire component 101, and can be rolled together as the retractable wire component 101 rotates. The other end of the traction rope 102 passes through the through-type jack 103 and is fixed by anchor plates, etc. It is fixed on the first vehicle body 201 and / or the heavy object; the through-type jack 103 is provided with upper and lower clamps and components such as anchor loosening and anchor tightening sensors, the traction rope 102 passes through it and is clamped by its upper and lower clamps. The upper and lower clamps move alternately and, in combination with the extension and contraction of the hydraulic cylinder, the traction rope 102 can be shuttled through it to lift or lower the steel pipe to a predetermined height. The front end of the through-type jack 103 is close to the jack limit component 104 to limit its displacement in the direction of the steel pipe. At the same time, a concrete fixing platform can be poured in advance at the rear to fix the through-type jack 103, and the hydraulic pump station, the electronic control system, etc. are installed in appropriate positions and correctly connected to the corresponding equipment;

[0098] Alternatively, at least one winch is fixed in advance at a suitable position on the upper flat section using bolts, ground anchors, etc., and the winch of each winch is connected to the traction rope 102, and one end of all the traction ropes 102 is connected to the first vehicle body 201 and / or the heavy object;

[0099] Alternatively, the tractor is placed on the upper flat ground, the tractor is connected to one end of the traction rope 102, and the other end of the traction rope 102 is connected to the first vehicle body 201 and / or a heavy object.

[0100] S3. Connect the first car body 201 and the second car body 203 to the connecting frame 202 through the hinge shaft 204 respectively, and fix the first support part 207 and the second support part 209 on the fixed support seat 206 of the connecting frame 202 and the lifting rod 210 respectively. Note that when the lifting rod 210 is installed on the fixed sleeve 208, the boss on the limit cover 211 needs to be clamped in the sliding groove of the lifting rod 210, wherein the first support part 207 is located on the side close to the first car body 201, and the second support part 209 is located on the side close to the second car body 203. At the same time, install the hydraulic system and electronic control equipment of the roller frame connected to the trolley 200, and install the electronic control equipment of the drive component 214.

[0101] After all components are installed and debugged, the steel pipe can be transported, including:

[0102] S4. The rollers on both sides of the first car body 201 and the second car body 203 are opened to the lowest point, and the welded steel pipe section is hoisted onto the connecting frame 202 by a crawler crane. The support ring on the steel pipe section is close to the second support part 209 on the front side. The steel pipe and the connecting frame 202 are tied and fixed by steel wire ropes. At the same time, the second support part 209 is fixed to the support ring by welding or magnetic fixing (if rubber is installed on the contact surface between the second support part 209 and the steel pipe, it can be not fixed). The second support part 209 rises and falls synchronously with the steel pipe, which plays a role in limiting the position of the steel pipe during the lifting process.

[0103] S5. In the flat section of the track 105, the trolley 200 drives the wheels to move forward along the track 105 through the driving component 214. It is necessary to control the running speed of the trolley 200 in the flat section so that the moving speed of the trolley 200 matches (slightly lower than) the speed of the through-type jack 103 driving the traction rope 102, ensuring that the traction rope 102 is always in a stress-free state in the flat section. At the same time, the retractable wire component 101 always rotates according to the running speed of the traction rope 102 to spit out the traction rope 102;

[0104] Alternatively, the moving speed of the trolley 200 matches (slightly lower than) the winch pay-off speed of the hoist, ensuring that the traction rope 102 is always in a stress-free state during the flat section;

[0105] Alternatively, the moving speed of the trolley 200 matches (is slightly lower than) the moving speed of the tractor, ensuring that the traction rope 102 is always in a stress-free state during the flat section.

[0106] S6. When the trolley 200 enters the inclined section from the flat section of the track 105, the driving component 214 is not needed to drive the trolley 200 forward. The trolley 200 moves downward along the track 105 under the action of gravity, and the traction rope 102 is always in a tensioned state. The through-type jack 103 drives the traction rope 102 to play a role of traction and lowering, so as to keep the trolley 200 carrying the steel pipe moving smoothly on the slope, and avoid the unsafe situation caused by its excessive sliding speed. Since the rollers 106 are installed at the transition bend in advance, the traction rope 102 contacts the rollers 106 when it is in the bend, and the rollers 106 rotate with the movement of the traction rope 102, thereby reducing the friction of the traction rope 102 and effectively protecting the traction rope 102 from being damaged by friction with the ground.

[0107] Alternatively, the hoist drives the traction rope 102 to pull the device downward.

[0108] Alternatively, the tractor drives the traction rope 102 to pull the vehicle downward.

[0109] After the steel pipe is lowered into place, the installation of the steel pipe can be carried out, including:

[0110] S7. The rollers on both sides of the trolley 200 are raised and pressed against the outer wall of the steel pipe, and the fixed wire ropes between the steel pipe and the connecting frame 202 are loosened. The rollers are then controlled to continue to rise, and the steel pipe is lifted to the installation height. At the same time, the second support part 209 is synchronously raised and lowered to limit the steel pipe during the lifting process. The left and right angles of the steel pipe are adjusted by using the rollers to ensure that it can be accurately aligned and installed. The end of the steel pipe section is then welded together with the installed steel pipe section. After the welding is completed, since the front end of the steel pipe section is in a suspended state, a temporary support needs to be set at its front end. The temporary support can be made by welding with profiles, etc. When installing the next section of the steel pipe section, after welding is completed, the previously installed temporary support needs to be removed, and then a temporary support needs to be set at the front end again.

[0111] S8. After the temporary support is installed, the second support part 209 is separated from the steel pipe support ring. At this time, the second support part 209 falls back to the lowest point. At the same time, the first support part 207 on the rear side is removed or flipped over and fixed on the trolley 200, so that the trolley 200 can transport it back for the next transportation. Then, the roller falls back to the lowest point, and the movement direction of the through-type jack 103 and the retractable wire component 101 is adjusted from lowering to lifting. The trolley 200 is lifted to the starting position of transportation.

[0112] Repeat the above steps S4 to S8 until all the steel pipes are installed, and then remove the retractable wire component 101, the through-type jack 103, the hydraulic pump station, the electronic control system, the jack limit component 104, the trolley 200, the track 105 and the roller 106.

[0113] The slope transportation and installation method of a steel pipe described in this embodiment is that the trolley 200 drives the heavy object from the flat section of the track 105 into the curved section, and the curved section into the inclined section. When the trolley 200 and the heavy object are in the curved section and the inclined section, they tend to move downward along the curved section and the inclined section under the action of their own gravity. The traction rope 102 is retracted and released by the traction and lifting system. The traction rope 102 is tensioned and stressed only after the trolley 200 enters the curved section and the inclined section, so that the trolley 200 remains stable when moving in the curved section and the inclined section. The traction and lifting system and the The combination of the trolley 200 is used for the inclined transportation of heavy objects, which improves the transportation capacity and has a high degree of intelligence. The steel pipe is lifted by the roller, and the steel pipe support ring is limited during the lifting process by the second support part 209. After the steel pipe section is welded and connected and a temporary support is installed, the second support part 209 and the roller can fall back, which can facilitate the retreat of the trolley 200 and solve the problem of difficulty in retreating the trolley 200 due to the support ring protrusion on the steel pipe section. The slope transportation and installation method of the steel pipe is simple in steps, easy to operate, and has good results.

[0114] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
