Description

[0001] The invention belongs to the technical field of water conservancy and hydropower, in particular to a support frame for water conservancy and hydropower engineering construction. Background Art

[0002] Water conservancy and hydropower projects are the basic industries for national economic and social development. Due to their large scale and long construction period, and the fact that they are greatly affected by natural resources, topography, geology, hydrology, meteorology and other conditions, the construction plan is different from conventional onshore infrastructure. Not only are there differences in the types of projects, but also there are targeted characteristics in terms of construction methods and process requirements. In water conservancy and hydropower projects, it involves the comprehensive utilization of water bodies in the natural environment. Therefore, infrastructure built on water bodies such as rivers and lakes occupies an important position in water conservancy and hydropower projects.

[0003] When repairing equipment at high places, if cracks appear in the pipeline, it is usually necessary to weld the cracks or cut out the cracks before welding. During welding, the pipeline will be deformed downward due to the cracks.

DETAILED DESCRIPTION

[0033] The following will be used in conjunction with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1As shown, the present invention provides a support frame for water conservancy and hydropower engineering construction, including a base plate 1, the lower end surface of the base plate 1 is evenly arranged with a plurality of support columns 11 connected thereto, and the lower end surfaces of the support columns 11 are connected to universal wheels 12; the top surface of the base plate 1 is provided with a lifting mechanism 2, a horizontal moving mechanism 3, and an auxiliary mechanism 4.

[0035] like Figure 2 As shown, the lifting mechanism 2 includes a support plate 21 fixedly connected to one side of the top surface of the base plate 1, a motor 22 is fixedly connected to one side of the support plate 21, a rotating shaft 23 is connected to the output end of the motor 22, a screw rod 24 is fixedly connected to one end of the rotating shaft 23, the screw rod 24 is meshed with a worm gear 25, and both sides of the worm gear 25 are connected to a first lifting assembly 26 and a second lifting assembly 27.

[0036] The above scheme is adopted: the starting motor 22 drives the rotating shaft 23 to rotate, and drives the screw rod 24 to rotate clockwise and engage with the worm wheel 25 to rotate counterclockwise. After the worm wheel 25 is subjected to force, it drives the transmission rod 271 on the first lifting component 26 and the second lifting component 27. Through the cooperation of the screw rod 24 and the worm wheel 25, the lifting plate 276 can be automatically locked after stopping, and the lifting plate 276 will not automatically move downward.

[0037] like Figure 2 , Figure 3 , Figure 4 As shown, the second lifting assembly 27 includes a transmission rod 271 fixedly connected to a side of the worm gear 25, one end of the transmission rod 271 penetrates a fixed plate 272, and a gear 273 is sleeved on the top of the transmission rod 271, and the gear 273 is meshed with a rack 274, the upper end of the rack 274 penetrates a first square opening 2751 opened on the upper end surface of the device 275, and the upper end of the rack 274 is fixedly connected to a lifting plate 276, and the lower end surface of the lifting plate 276 is equidistantly connected to a plurality of guide rods 27 7. A first through hole 2752 is penetrated at the lower end of the guide rod 277, and the first through hole 2752 is provided on both sides of the upper end surface of the device 275. A second through hole 278 is extended through the lower end of the guide rod 277, and the second through hole 278 is provided on both sides of the top surface of the bottom plate 1. A second square opening 279 is extended through the lower end of the rack 274, and the second square opening 279 is provided on the upper end surface of the bottom plate 1. The first lifting assembly 26 and the second lifting assembly 27 have the same structure.

[0038] By adopting the above scheme: the transmission rod 271 is forced to rotate counterclockwise in the support hole on the fixed plate 272, and at the same time, the transmission rod 271 also drives the gear 273 to rotate counterclockwise and engage with the rack 274, so that the rack 274 is forced to move upward, and the rack 274 penetrates upward into the first square opening 2751 and the second square opening 279, and the rack 274 drives the lifting plate 276 upward. When the lifting plate 276 is forced to move upward, the lifting plate 276 is driven by the guide rod 277 to slide upward inside the first through hole 2752 and the second through hole 278. The guide rod 277 can ensure that the lifting plate 276 moves upward stably to prevent the lifting plate 276 from shaking during the rise.

[0039] like Figure 4 , Figure 5 As shown, the horizontal moving mechanism 3 includes a handle 31, a side of which is fixedly connected to a screw rod 32, one end of which is penetrated by a bearing plate 33, the lower end surface of which is fixedly connected to one side of the upper end surface of the lifting plate 276, one end of the screw rod 32 is meshed with a moving plate 34, the lower end surface of which is connected to a sliding plate 341 equidistantly arranged along the length direction, a spiral hole 342 is provided inside the sliding plate 341, the spiral hole 342 is meshed and transmitted to the screw rod 32, the sliding plate 341 is slidably matched with a sliding groove 2761, the sliding grooves 2761 are equidistantly arranged along the length direction and are all opened on the top surface of the lifting plate 276.

[0040] The above scheme is adopted: manually hold the handle 1 and apply force to make the spiral rod 32 engage with the spiral hole 342, and the engaging force is transmitted to the sliding plate 341 and the movable plate 34. If the pipeline 13 is horizontally offset to the left during installation, the spiral rod 32 engages with the spiral hole 342 clockwise, and the engaging power is transmitted to the movable plate 34. The movable plate 34 is forced to slide to one side inside the sliding groove 2761, and drives the pipeline 13 between the first clamping block 36 and the second clamping block 37 to move to the right as a whole until the pipeline 13 is completely matched, then stop applying force to the handle, and use the engagement of the spiral rod 32 and the spiral hole 342 to make the adjustment work more convenient, thereby saving manual labor and speeding up the installation progress.

[0041] like Figure 6As shown, the upper end surface of the movable plate 34 is provided with clamping grooves 343 arranged equidistantly along the length direction, and a first spring body 35 is fixedly connected to one side of the clamping groove 343, and a first clamping block 36 is fixedly connected to one end of the first spring body 35, and a first placement surface 361 is provided at the lower part of one side of the first clamping block 36, and a first inclined surface 362 is provided at the top end of one side of the first clamping block 36, and the first inclined surface 362 and the first placement surface 361 are in contact with the pipeline 13, and the outer side of the pipeline 13 is in contact with the second clamping block 37, and a second placement surface 371 is provided at the lower part of one side of the second clamping block 37, and a second inclined surface 372 is provided at the top end of one side of the second clamping block 37, and the second spring body 38 is fixedly connected to the other side of the second clamping block 37.

[0042] The above scheme is adopted: the pipe 13 is placed between the first clamp block 36 and the second clamp block 37 by staff or other equipment. During the placement, the outer side of the pipe 13 is first pressed against the first inclined surface 362 and the second inclined surface 372, and the pipe 13 is made to slide downward by the inclined guide. The first clamp block 36 and the second clamp block 37 are slid to both sides inside the sliding groove 2761 by the diameter of the pipe 13, and the first clamp block 36 is pressed on one side by the first spring body 35, and the second clamp block 37 is pressed on the other side by the second spring body 38. After the pipe 13 gradually slides downward to the first placement surface 361 and the second placement surface 371, it is completely fixed to the pipe 13, which is conducive to clamping pipes 13 of different sizes and makes the work of placing and fixing the pipe 13 more convenient.

[0043] like Figure 7 , Figure 8 , Fig. 9 As shown, the auxiliary mechanism 4 includes an extension frame shell 41 fixedly connected to a side of the movable plate 34, and the extension frame shell 41 is rotatably matched with an auxiliary plate 43 through a fixed rod 42, and the first stop block 431 and the second stop block 432 are connected to both sides of the top end surface of the auxiliary plate 43, and the first clamping block 433 and the second clamping block 434 are fixed to the upper end surface of the auxiliary plate 43, and the first tilting component 44 and the second tilting component 45 are provided on the lower end surface of the auxiliary plate 43.

[0044] The above scheme is adopted: if the crack of the repair pipe 13 is large, the crack of the pipe 13 is first cut off. After cutting, the last fixed end of the pipe 13 is found first, and this end is used as the positioning point. After adjustment, the lifting mechanism 2 is started to lift the auxiliary plate 43 upward, wherein the first stopper 431 on the auxiliary plate 43 first contacts the cut end of the pipe 13. As the movable plate 34 continues to move upward, the first stopper 431 is resisted by the pipe 13, so that the side of the auxiliary plate 43 under force is rotated downward to the outside of the fixing rod 42, and the second stopper 431 on the other side of the auxiliary plate 43 is rotated upward. Under the gradual pressure of the pipe 13, the upper surface of the second stopper 431 contacts the other end of the cut pipe 13. At this time, the auxiliary plate 43 is rotated to a horizontal state, and the unstable part of the cut pipe 13 can be fixed at the end with the positioning point. The fixed port is lifted up to the horizontal line of the positioning point, so that the welding effect of the pipe 13 is better during welding, and water leakage is prevented from occurring again due to the two ends of the pipe no longer being on the same horizontal line. Therefore, the welded pipe is more durable and has a longer service life. After being lifted up to a horizontal state, the supplementary pipe 13 is first placed on the inclined surface of the first clamp block 433 and the second clamp block 434. There is no need to take out the supplementary pipe 13 from other places during welding. It can be directly placed on the inclined surface of the first clamp block 433 and the second clamp block 434, which reduces the step of manually taking out the supplementary pipe 13 and speeds up the work progress. When the diameter of the supplementary pipe 13 is small, the port can be placed inside the first clamp block 433 and the second clamp block 434, which effectively prevents the supplementary pipe 13 from falling outward during the upward movement, and then the supplementary pipe 13 is taken out for welding incision.

[0045] like Fig.10 As shown, the first tilting component 44 includes a fixed block 441 fixedly connected to the inner wall of the extension frame shell 41, one side of the fixed block 441 is fixedly connected to a third spring body 442 through an inclined surface, the upper end of the third spring body 442 is fixedly connected to the lower end of the auxiliary plate 43, and one side end surface of the fixed block 441 is connected to a first folding plate 443 through a first connecting rod, the first folding plate 443 is connected to a second folding plate 444 through a second connecting rod, and one side of the second folding plate 444 is connected to a folding groove 435 through a third connecting rod, and the folding groove 435 is opened on one side of the bottom end of the auxiliary plate 43.

[0046] The above scheme is adopted: when repairing the crack deformation of the pipeline 13, the movable plate 34 is first pushed upward by the lifting mechanism 2, and the extension frame shell 41 is also driven to move upward, and the auxiliary plate 43 on the extension frame shell 41 also moves upward, and the first stop block 431 on the auxiliary plate 43 first contacts one end of the crack on the outside of the pipeline 13. When the movable plate 34 continues to move upward, the first stop block 431 is resisted by the pipeline 13, so that the side of the auxiliary plate 43 under force is rotated downward to the outside of the fixed rod 42, and the second stop block 431 on the other side of the auxiliary plate 43 is rotated upward. Under the gradual pressure of the pipeline 13, the upper surface of the second stop block 431 contacts the other end of the crack on the outside of the pipeline 13. At this time, the auxiliary plate 43 is rotated to When the auxiliary plate 43 is rotated to the horizontal state, the third spring body 442 on the first tilting component 44 and the second tilting component 45 is stretched first. At the same time, the third connecting rod on the folding groove 435 pulls up the second folding plate 444. The second folding plate 444 is forced to pull up the first folding plate 443 through the second connecting rod, so that one side of the first folding plate 443 rotates upward and the other side rotates on the outside of the first connecting rod. Through the arrangement of the first folding plate 443, the third spring body 442 and the second folding plate 444, the auxiliary plate 43 can rotate more stably. After the auxiliary plate 43 is used, the elastic force of the third spring body 442 makes the auxiliary plate 43 return to its original position, so that the first stop block 431 maintains its original tilted state.

[0047] Among them, the upper end surface of the auxiliary plate 43 is abutted against the lower end surface of the abutment plate 445, and under the horizontal resistance of the first abutment block 431 and the second abutment block 431, the cracked pipe 13 returns to its original horizontal state. After the pipe 13 is horizontal, during the welding process, the deformed and cracked pipe can be lifted up to a horizontal state through the auxiliary plate 43 without the participation of other equipment, thereby realizing the effect of one machine with multiple functions. After lifting the horizontal line, the cracks of the pipe 13 are aligned, and the bent pipe is in a horizontal line shape. If it can be welded, the work of the weldable pipe 13 is relatively simple, and its welding effect is better. If it cannot be welded, it can be directly cut off and then the incision of the pipe 13 can be supplemented, thereby improving the convenience of labor and speeding up the maintenance progress.

[0048] like Figure 7 As shown, one side of the upper end surface of the auxiliary plate 43 abuts against a stop plate 445 , and the first tilting component 44 and the second tilting component 45 have the same structure.

[0049] The above solution is adopted to prevent the auxiliary plate 43 from exceeding the horizontal angle and to prevent the pipes 13 from not being on the same horizontal line.

[0050] like Figure 8 As shown, the auxiliary plate 43 is in a horizontal state during operation, wherein the lower outer portion of the pipe 13 abuts against the upper surfaces of the first abutment block 431 and the second abutment block 431 .

[0051] The above scheme is adopted: it is advantageous that welding can be performed regardless of crack welding or crack cutting, and both can be pushed to the same horizontal line, which can save time and labor for manual work, thereby improving work performance.

[0052] The working principle and use process of the present invention:

[0053] If it is necessary to install the pipe 13, first, the staff or other equipment will place the pipe 13 between the first clamp block 36 and the second clamp block 37. During the placement, the pipe 13 will slide downward by utilizing the first inclined surface 362 and the second inclined surface 372, and the first clamp block 36 and the second clamp block 37 will be forced to slide to both sides inside the sliding groove 2761 and squeeze the first spring body 35 and the second spring body 38 until the pipe 13 is pressed against the first placement surface 361 and the second placement surface 371 on the outside and is fixed to the pipe 13.

[0054] After fixing the pipeline 13, start the motor 22 to drive the rotating shaft 23 to rotate, and drive the screw rod 24 to rotate clockwise and mesh with the worm gear 25 to rotate counterclockwise. After the worm gear 25 is subjected to force, it drives the transmission rod 271 on the first lifting component 26 and the second lifting component 27. The transmission rod 271 is subjected to force to drive the gear 273 counterclockwise. The gear 273 meshes with the rack 274 and moves upward. The rack 274 is forced to drive the lifting plate 276 upward. When the lifting plate 276 is forced to move upward, the lifting plate 276 is driven by the guide rod 277 to slide upward inside the first through hole 2752 and the second through hole 278. The guide rod 277 can ensure that the lifting plate 276 moves upward stably to prevent the lifting plate 276 from shaking during the rise.

[0055] Before starting the lifting mechanism 2, push the device to the maintenance or installation location, and then start the motor 22. During the upward movement of the lifting plate 276, due to the offset of the position where the device is placed, it is necessary to push the device for adjustment, which is inconvenient. In order to solve this problem, a horizontal moving mechanism 3 is provided. When the pipe 13 is horizontally offset to the left during installation, the spiral rod 32 engages in the spiral hole 342 clockwise, and the power of the engagement is transmitted to the moving plate 34. The moving plate 34 is forced to slide to one side inside the sliding groove 2761, and the fixed pipe 13 is moved to the right as a whole until the pipe 13 is completely matched with the port where the pipe 13 is installed, and then the moving plate 34 can be stopped.

[0056] For example, when repairing a crack or deformation of the pipe 13, the movable plate 34 is first pushed upward by the lifting mechanism 2, and the extension frame shell 41 is also driven to move upward, so that the first stopper 431 of the auxiliary plate 43 first contacts one end of the crack on the outside of the pipe 13. As the movable plate 34 continues to move upward, the second stopper 431 rotates upward. As the pipe 13 is gradually pressed, the upper surface of the second stopper 431 contacts the other end of the crack on the outside of the pipe 13. At this time, the auxiliary plate 43 rotates to a horizontal state.

[0057] When the auxiliary plate 43 rotates to a horizontal state, the third spring body 442 is stretched first. At the same time, the third connecting rod on the folding groove 435 pulls up the second folding plate 444. The second folding plate 444 is forced to pull up the first folding plate 443 through the second connecting rod until the upper end surface of the auxiliary plate 43 is blocked by the lower end surface of the stop plate 445. At this time, the auxiliary plate 43 rotates to a horizontal state. Under the horizontal contact between the first stop block 431 and the second stop block 431, the cracked pipe 13 is first returned to its original horizontal state before welding.

[0058] When the crack of the repaired pipe 13 is large, the crack of the pipe 13 is first cut off. After cutting, the last fixed end of the pipe 13 is first found and this end is used as the positioning point. After adjustment, the lifting mechanism 2 is started to push the auxiliary plate 43 upward, so that the first stop block 431 first contacts the cut end of the pipe 13. As the movable plate 34 continues to move upward, the upper surface of the second stop block 431 contacts the other end of the cut pipe 13. At this time, the auxiliary plate 43 rotates to a horizontal state. At one end of the positioning point, the unstable port of the cut pipe 13 can be lifted up to the horizontal line of the positioning point. After lifting it to a horizontal state, the supplementary pipe 13 that has been placed on the inclined surfaces of the first block 433 and the second block 434 is taken out, so as to weld the incision.
