Description

Technical Field

[0001] The utility model relates to the technical field of construction auxiliary tools, in particular to a dam surface cooling water pipe collecting tool. Background Art

[0002] Pre-buried cooling water pipes inside the dam body can reduce the initial temperature difference between the inside and outside of the concrete, control the maximum temperature inside the concrete, and thus meet the requirement of uniform cooling of the dam body. In order to avoid the excessive opening of the joint surface in the later stage, the cooling water pipes are directly laid on the warehouse surface as a whole, making full use of their relatively easy-to-bend characteristics. The cooling water pipes are arranged in a serpentine shape independently in each dam section. Cooling water pipes usually use HDPE pipes, which have a certain degree of flexibility. HDPE pipe reels are transported to the warehouse surface in bundles. During the construction process, the HDPE pipes are laid in the warehouse by manpower. Repeated dragging of the HDPE pipes can easily cause pollution and damage to the HDPE pipes. Utility Model Content

[0003] In order to solve the above problems, the present invention provides a new type of dam surface cooling water pipe collection tool.

[0004] The technical solution adopted by the utility model is:

[0005] A dam surface cooling water pipe collection tool, the dam surface cooling water pipe collection tool comprises a base, a vertical axis, a supporting turntable and a top bearing; the base adopts a cross-type base, which is placed on the ground, the vertical axis is fixedly installed at the center of the base, the top of the vertical axis is installed with a top bearing, the supporting turntable is rotatably installed on the vertical axis through the top bearing, and bundles of cooling water pipes can be placed on it.

[0006] Furthermore, the base is formed by welding two crossed channel steels.

[0007] Furthermore, the supporting turntable includes a steel casing and supporting steel bars; the steel casing is sleeved on the vertical axis, the top end of which is fixedly connected to the top bearing, and the bottom of which has a certain space gap from the base; a plurality of supporting steel bars are arranged around the steel casing as the center circle and extend horizontally outward, and one end of the supporting steel bars is fixedly connected to the outer tube wall at the bottom of the steel casing.

[0008] Furthermore, the number of the supporting steel bars is at least four, and the four supporting steel bars are arranged at equal angles with the steel casing as the center.

[0009] Furthermore, an obliquely arranged structural reinforcement steel bar is fixedly connected between the top end of the steel casing and each supporting steel bar.

[0010] Furthermore, an inner ring round steel is fixedly connected to the supporting steel bar; and an outer ring round steel is fixedly connected to one end of the supporting steel bar away from the steel casing.

[0011] The beneficial effects of the utility model are:

[0012] The dam surface cooling water pipe collection tool can be used to place bundled cooling water pipes on the support turntable. When in use, the end of the cooling water pipe is manually dragged, and the support turntable rotates clockwise or counterclockwise relative to the vertical axis through the top bearing to drag the cooling water pipe to a length suitable for construction and laying, and then it is arranged back and forth. During the arrangement process, since the bundled cooling water pipes do not form friction with the ground, the cooling water pipes can be prevented from being damaged during the laying process. In addition, if the cooling water pipes are pulled too much during laying, the support turntable can be rotated in the opposite direction to collect the cooling water pipes back to avoid contamination of the water pipes.

[0013] The dam surface cooling water pipe collection tool is simple to make and easy to use, which greatly reduces the manual dragging of water pipes, ensures the quality of cooling water pipes during construction, and greatly improves construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings of 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. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] This embodiment provides a dam surface cooling water pipe collection tool, such as Figure 1As shown, the dam surface cooling water pipe collecting tool includes a base 1, a vertical axis 2, a supporting turntable 3 and a top bearing 4; the base 1 is placed on the ground, serving as a supporting structure for the entire dam surface cooling water pipe collecting tool; the vertical axis 2 is fixedly mounted on the base 1, serving as a supporting axis structure for the supporting turntable 3, ensuring that the supporting turntable 3 can rotate while preventing the cooling water pipes on the supporting turntable 3 from contacting the ground; the supporting turntable 3 is rotatably mounted on the vertical axis 2 through the top bearing 4, on which bundles of cooling water pipes can be placed, serving as a bearing structure for the bundles of cooling water pipes.

[0020] like Figure 2 As shown, the base 1 in this embodiment adopts a cross-type base 1, which is welded by two cross No. 20 channel steels; the vertical shaft 2 is welded and fixed at the center of the base 1 to support the support turntable 3. The vertical shaft 2 is made of Φ28 threaded steel and has a length of 1.2m. The top of the vertical shaft 2 is installed with a top bearing 4, and the bearing uses a commercially available finished bearing product. Figure 3 As shown, the support turntable 3 includes a steel casing 5 and support steel bars 6; the steel casing 5 is a Φ32 steel pipe with a length of 1m. The steel casing 5 is sleeved on the vertical shaft 2, and the top end is fixedly connected to the top bearing 4; because the length of the steel casing 5 is shorter than the length of the vertical shaft 2, there is a space gap of about 20cm between the bottom of the steel casing 5 and the base 1. Four support steel bars 6 are arranged at equal angles around the steel casing 5 and extend horizontally outward. The support steel bars 6 are Φ12 steel bars with a length of 1m. One end of the support steel bar 6 is welded and fixed to the outer pipe wall at the bottom of the steel casing 5. If the bundled cooling water pipes are heavy, the number of support steel bars 6 can also be increased according to actual needs.

[0021] Further, as a preferred technical solution of this embodiment, in order to increase the structural strength of the supporting turntable 3, as Figure 3 As shown, in this embodiment, an inclined structural reinforcement steel bar 7 is welded and fixed between the top of the steel casing 5 and each supporting steel bar 6. The structural reinforcement steel bar 7 is a 12-diameter steel bar. The structural reinforcement bar increases the connection strength between the supporting steel bar 6 and the steel casing 5. In addition, an inner ring round steel bar 8 is welded and fixed to the supporting steel bar 6, and an outer ring round steel bar 9 is welded and fixed to the end of the supporting steel bar 6 away from the steel casing 5. Both the inner ring round steel bar 8 and the outer ring round steel bar 9 are 10-diameter round steels, so as to increase the structural strength between the supporting steel bars 6.

[0022] The dam surface cooling water pipe collection tool is used as follows:

[0023] The dam surface cooling water pipe collection tool can be used to place bundled cooling water pipes on the support turntable 3. When in use, the end of the cooling water pipe is manually dragged, and the support turntable 3 rotates clockwise or counterclockwise relative to the vertical axis 2 through the top bearing 4 to drag the cooling water pipe to a length suitable for construction and laying, and then it is arranged back and forth; during the arrangement process, since the bundled cooling water pipes do not form friction with the ground, the cooling water pipes can be prevented from being damaged during the laying process. In addition, if the cooling water pipes are pulled too much during laying, the support turntable 3 can be rotated in the opposite direction to collect the cooling water pipes again to prevent the water pipes from being contaminated.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
