[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model discloses a temporary support device for steel pipes in a groove, comprising two moving platforms 1, a vertical pole 2 is arranged on the top of the moving platform 1, a support pole 3 is rotatably arranged on opposite sides of the two vertical poles 2, the spacing between the two vertical poles 2 is greater than the sum of the lengths of the two support poles 3, and a splicing assembly 4 is arranged between the two support poles 3;

[0024] The splicing assembly 4 includes two first threaded rods 41, which are respectively threadedly installed on the bottom of the two support rods 3, and the sum of the lengths of the two first threaded rods 41 is greater than the spacing between the two vertical rods 2. The vertical rods 2 are provided with strip holes for the first threaded rods 41 to rotate. The first threaded rods 41 are parallel to the support rods 3. A sleeve 42 is provided at one end of one of the first threaded rods 41 close to the other first threaded rod 41, and the inner diameter of the sleeve 42 is equal to the outer diameter of the first threaded rod 41.

[0025] The utility model places the assembled temporary support device of the steel pipe in the groove, places the steel pipe on the support rod 3 connected by the splicing component 4 for welding, and after the short water supply pipe is welded into the long water supply pipe, the connection of the splicing component 4 is released to make the long water supply pipe fall into the groove. At this time, it is only necessary to dig a welding pit corresponding to the long water supply pipe in the groove, thereby reducing the number of welding pits when laying the water supply pipe and improving the construction efficiency of the water supply pipe.

[0026] It should be noted that each water supply pipe requires at least two temporary steel pipe support devices for support. After the water supply pipe is welded, it is necessary to first release the splicing assembly 4 that provides support for the middle part of the water supply pipe, and finally release the splicing assembly 4 that provides support for both ends of the water supply pipe at the same time, so that the entire water supply pipe can fall into the groove as synchronously as possible.

[0027] In the specific implementation, at least two universal wheels are provided at the bottom of the mobile platform 1, so that the spliced ​​temporary support device of the steel pipe can be moved in the groove. When a section of the water supply pipe is welded, the temporary support device of the steel pipe can be directly pushed to move to the next section of the water supply pipe that needs to be lifted and supported. There is no need to dismantle and transfer the temporary support device of the steel pipe as a whole, thereby further improving the construction efficiency.

[0028] In one embodiment, a balancing rod 5 is detachably provided between the top ends of the two vertical rods 2 , and when the balancing rod 5 is parallel to the supporting rod 3 , the distance between the balancing rod 5 and the supporting rod 3 is greater than the diameter of the water supply pipe.

[0029] This design allows the assembled temporary steel pipe support device to form a complete rectangle at the top, improving the support firmness and pressure resistance. At the same time, after the splicing assembly 4 below is released, the vertical poles 2 on both sides can still remain connected, which is convenient for pushing and transferring.

[0030] In one embodiment, an auxiliary alignment component 6 for pushing the alignment of the welding end of the water supply pipe is provided on the top of the support rod 3; the auxiliary alignment component 6 includes a vertical plate 61 arranged on the top of the support rod 3, and a second threaded rod 62 parallel to the support rod 3 is threadedly provided on the vertical plate 61, and a push plate 63 slidably connected to the support rod 3 is rotatably provided at one end of the second threaded rod 62 away from the adjacent vertical rod 2.

[0031] With this design, when the two water supply pipes are not completely aligned at the welding points, the second threaded rods 62 on both sides can be rotated to change the position of the push plate 63 so that the push plate 63 pushes the water supply pipes to make fine adjustments in the horizontal direction.

[0032] In a specific implementation, the screwing ends of the first threaded rod 41 and the second threaded rod 62 are both provided with hexagonal caps for connection with a hexagonal wrench, so that construction workers can easily obtain adjustment tools.

[0033] In one embodiment, a positioning assembly 7 for assisting the first threaded rod 41 to be inserted into the sleeve 42 is provided on the vertical rod 2; the positioning assembly 7 includes a rotating support 71 provided on the vertical rod 2, and a C-shaped positioning frame 72 capable of horizontal rotation is provided on the rotating support 71. When one end of the first threaded rod 41 is inserted into the sleeve 42, the C-shaped positioning frame 72 can rotate and be sleeved onto the first threaded rod 41.

[0034] With this design, the first threaded rod 41 is positioned by the C-shaped positioning frame 72, which is convenient for assisting the first threaded rod 41 to be inserted into the sleeve 42 when the splicing component 4 is assembled. At the same time, after the splicing component 4 is separated, the C-shaped positioning frame 72 can temporarily bear the weight of the water supply pipe. Thereafter, by connecting a pull rope to the C-shaped positioning frame 72 and pulling the pull rope, the restrictions of multiple C-shaped positioning frames 72 on the first threaded rod 41 can be released at the same time, so that the support rod 3 is rotated downward by the gravity of the water supply pipe, allowing the water supply pipe to contact the bottom of the groove pit.

[0035] In one embodiment, a buffer component 8 for mitigating the impact force of the water supply pipe against the ground when it falls is detachably provided on the top of the mobile platform 1;

[0036] The buffer assembly 8 comprises an L-shaped bracket 81 detachably arranged on the top of the mobile platform 1, the L-shaped bracket 81 is composed of a vertical section connected to the mobile platform 1 and a transverse section connected to the top of the vertical section, a support plate 82 is rotatably arranged at one end of the transverse section away from the vertical section, a hydraulic buffer 83 is arranged at one end of the vertical section close to the support plate 82, and a connecting block 84 slidably connected to the support plate 82 is rotatably arranged at one end of the hydraulic buffer 83 close to the support plate 82;

[0037] When the hydraulic buffer 83 is in a natural state, the two support plates 82 are arranged in a V shape, and when the two support plates 82 are parallel, the distance between the two support plates 82 is greater than the diameter of the water supply pipe.

[0038] This design ensures that when the water supply pipe falls, it will touch the extrusion support plate 82, compressing the hydraulic buffer 83. In this process, the impact force of the water supply pipe falling is reduced to ensure that the water supply pipe will not be damaged after being lowered.

[0039] In one embodiment, the mobile platform 1 is also provided with an adjustable support leg 9 for adjusting the placement height of the mobile platform 1; the adjustable support leg 9 includes a crossbeam, a lifting stud is threadedly provided on the crossbeam, and a support foot is provided at the bottom end of the lifting stud. By rotating the lifting stud, the height of the support foot is adjusted, thereby changing the placement height of the mobile platform 1, so that when the bottom of the trench pit is uneven, the water supply pipe can still be kept at the same lifting height.

[0040] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.
