[0012] like Figures 1 to 4 As shown, the utility model fire-fighting pipe installation auxiliary tool comprises an upper rod 20 and a lower rod 10. Usually, the length of the upper rod 20 is greater than that of the lower rod 10. The upper rod 20 can be inserted into the lower rod 10 movably up and down. A U-shaped top support 30 is provided on the top of the upper rod 20, and a base 40 is provided at the bottom of the lower rod 10, wherein: an upper turntable 50 is provided on the upper part of the upper rod 20, and a lower turntable 70 is provided on the upper part of the lower rod 10. A pull rope 60 is wound between the upper turntable 50 and the lower turntable 70, and a hook 61 is provided on the pull rope 60; a hand crank 90 is passed through and fixed on the lower turntable 70. The part of the hand crank 90 on one side of the lower turntable 70 is horizontally movably arranged on the limit piece 80 through the limit block 91, and the part of the hand crank 90 on the other side of the lower turntable 70 is used to manually rotate the lower turntable 70, and the limit piece 80 is fixed on the lower rod 10; when the hand crank 90 moves inward and is inserted into the lower rod 10 and the upper rod 20, the upper rod 20 is positioned relative to the lower rod 10, that is, the height adjustment of the top support 30 is completed; when the hand crank 90 moves outward and leaves the upper rod 20, the upper rod 20 can move up and down relative to the lower rod 10 to achieve height adjustment.

[0013] In actual design, Figure 1 and Figure 3 One end of the pull rope 60 is fixed on the lower turntable 70, and the other end of the pull rope 60 extends upward, bypasses the upper turntable 50, and then extends downward and is connected to the hook 61. The lower turntable 70 rotates under the rotation of the hand crank 90, so that the hook 61 moves up and down under the rotation of the upper turntable 50 through the pulling of the pull rope 60, wherein: the upper turntable 50 is covered in a turntable cover 51, and the turntable cover 51 is provided with a hole for allowing the pull rope 60 to enter and exit.

[0014] In the present invention, the purpose of designing the turntable cover 51 is to limit the hook 61 to prevent the hook 61 from falling off the upper turntable 50 due to excessive force. In actual design, the upper turntable 50 and the lower turntable 70 should be provided with grooves for accommodating the pull rope 60, which is a conventional design.

[0015] like Figure 1The base 40 can be welded by square tubes to form a plane, and a roller 41 with a self-locking function can be installed at the bottom of the base 40. The roller with a self-locking function is a prior art in this field and will not be described in detail here.

[0016] like Figure 4 The base 40 can also be designed as a foldable base with self-locking rollers. The foldable base is an existing component on the market. Generally, the foldable base includes a plurality of legs 42, one end of each leg 42 is foldably connected to the bottom of the lower rod 10 and the other end is equipped with a self-locking roller 43. The use of the foldable base can improve the storage and convenience of the utility model. When storage is required, such as Figure 4 , just fold up the legs 42 of the foldable base and place them against the lower rod 10, which takes up very little space.

[0017] In the present invention, the design of the roller facilitates the adjustment of the orientation of the jack 30 so that the fire-fighting pipe to be installed can be placed in alignment with the installed fire-fighting pipe.

[0018] In actual design, the U-shaped structure of the jacking support 30 may be an arc shape or a broken line shape, without limitation, as long as the jacking support 30 can stably support the fire protection pipe.

[0019] Preferably, if Figure 3 , supporting plates 31 can be extended on both sides of the top support 30, and the supporting plates 31 can be pulled out or pushed in from the top support 30. Specifically, in the actual design, the top support 30 is designed as a hollow structure with a slide groove inside, and sliders are provided on the supporting plates 31 on both sides. Based on the design of the sliders and the slide groove, the supporting plates 31 can slide relative to the top support 30, so that the supporting plates 31 slide into (push into) the top support 30 and the supporting plates 31 slide out (pull out) the top support 30. Of course, a limiting protrusion should be provided at the outermost end of the slide groove to prevent the supporting plates 31 from detaching from the top support 30.

[0020] When in use, the supporting plates 31 on both sides are pulled out from the top support 30 to increase the force bearing area of ​​the fire-fighting pipe, thereby improving the supporting stability and ensuring the smooth installation of the fire-fighting pipe. When folded, the supporting plates 31 on both sides are pushed into the top support 30.

[0021] like Figure 2 The limiting member 80 is provided with an inner cavity 81, and the two cavity openings 812 of the inner cavity 81 communicating with the outside are smaller than the middle part 811 of the inner cavity 81, that is, the cross-sectional area of ​​the cavity opening 812 of the inner cavity 81 is smaller than the cross-sectional area of ​​the middle part 811 of the inner cavity 81, and the inner cavity 81 is opposite to the through hole 11 provided on the lower rod 10, and the hand crank 90 is provided through the inner cavity 81, and the limiting block 91 fixed on the hand crank 90 is movably placed in the middle part 811 of the inner cavity 81, wherein:

[0022] The limit block 91 moves inward in the middle part 811 of the inner cavity 81, which can drive the hand crank 90 to move inward and insert into the through hole 11 on the lower rod 10 and the corresponding positioning hole 201 on the upper rod 20 (the lower turntable 70 moves inward together with the hand crank 90), so as to realize the positioning of the upper rod 20 relative to the lower rod 10;

[0023] By moving the limit block 91 outward in the middle part 811 of the inner cavity 81, the hand crank 90 can be driven to move outward away from the positioning hole 201 of the upper rod 20 (the lower turntable 70 moves outward with the hand crank 90), so that the upper rod 20 can move up and down relative to the lower rod 10 to achieve height adjustment.

[0024] In actual design, the shape and size of the stopper 80 are not limited. Preferably, the stopper 80 can be designed as an oblate cylindrical shape, and the cross-sectional size can be the same as or slightly smaller than that of the lower turntable 70. The inner cavity 81 on the stopper 80 is designed as a circular cross-sectional size. Correspondingly, the stopper block 91 fixed on the hand crank 90 is annular, and its cross-sectional size is adapted to the cross-sectional size of the middle part 811 of the inner cavity 81. In actual production, the stopper 80 can be designed to be formed by buckling and bonding two parts, so that the hand crank 90 and its upper limit block 91 can be placed in the inner cavity 81.

[0025] In the utility model, the upper rod 20 and the lower rod 10 are hollow structures. Preferably, the upper rod 20 and the lower rod 10 are made of square tubes. A plurality of positioning holes 201 are evenly spaced along the up and down directions on the upper rod 20, and a bearing 21 is provided in each positioning hole 201. The hand crank 90 moves inward and is inserted into the bearing 21 in the through hole 11 of the lower rod 10 and the corresponding positioning hole 201 of the upper rod 20 to realize the positioning of the upper rod 20 relative to the lower rod 10.

[0026] Specifically, the bearing 21 includes an inner ring and an outer ring, and the inner ring and the outer ring are connected by balls. The outer ring of the bearing 21 is fixed in the positioning hole 201 of the upper rod 20. After the hand crank 90 is inserted, the inner ring of the bearing 21 is used to reduce the friction when the hand crank 90 rotates, thereby achieving the purpose of saving effort.

[0027] Furthermore, in actual design, in order to facilitate the quick insertion of the hand crank 90 into the inner ring of the bearing 21, the distance between the through hole 11 and the top of the lower rod 10 can be designed to be consistent with the spacing between adjacent positioning holes 201 on the upper rod 20. In this way, when a positioning hole 201 on the upper rod 20 is at the top position of the lower rod 10, a positioning hole 201 below this positioning hole 201 or its inner bearing 21 is opposite to the through hole 11 on the lower rod 10.

[0028] In addition, in the actual design, by reasonably designing the length of the inner cavity 81 and the length of the limit block 91 from the end of the hand crank 90, on the one hand, after the limit block 91 drives the hand crank 90 to move inward into position, the length of the hand crank 90 extending into the upper rod 20 is sufficient to ensure the stable positioning of the upper rod 20. On the other hand, after the limit block 91 drives the hand crank 90 to move outward into position, the hand crank 90 can still be in the through hole 11 of the lower rod 10 after leaving the positioning hole 201 of the upper rod 20, thereby avoiding the through hole 11 from causing obstacles to the movement of the hand crank 90. ​​Of course, the purpose of avoiding the through hole 11 from causing obstacles to the movement of the hand crank 90 can also be achieved by designing the aperture of the through hole 11 to be much larger than the rod diameter of the hand crank 90.

[0029] In actual design, the hand crank 90 is arranged on the lower turntable 70, the hand crank 90 part on the inner side of the lower turntable 70 is straight, and the hand crank 90 part on the outer side of the lower turntable 70 can be designed to be bent, such as Figure 2 In addition, a rubber handle can be provided to achieve the purpose of saving effort and easy operation, and of course it is not limited.

[0030] In the present invention, the direction toward the interior of the upper rod 20 and the lower rod 10 is referred to as inward or inside, and conversely, the direction away from the interior of the upper rod 20 and the lower rod 10 is referred to as outward, and the inside and outside of the components are defined accordingly.

[0031] When in use, the utility model fire pipe installation auxiliary tool is moved to the working position through the roller design and the direction of the top support 30 is adjusted, and then the roller is locked. Then, according to the installation height requirement of the fire pipe, the hand crank 90 is pulled outward (the lower turntable 70 moves with the hand crank 90), so that the hand crank 90 moves out of the upper rod 20, and then the height of the upper rod 20 is adjusted. When the height of the top support 30 reaches the design elevation of the fire pipe, the hand crank 90 is pushed in (the lower turntable 70 moves with the hand crank 90), so that the hand crank 90 is inserted into the upper rod 20, so that the upper rod 20 is fixed, and the height adjustment is completed. Then the end of the fire pipe to be installed can be hung on the hook 61, and the hand crank 90 is rotated to lift the fire pipe to the top support 30 position. Then the worker who arrives at the working surface with the help of mechanical equipment places the fire pipe horizontally on the top support 30, and docks the fire pipe with the installed fire pipe through the relevant connecting parts, thereby completing the docking installation of the two fire pipes, saving time and effort, and ensuring the quality of the operation.

[0032] The advantages of the utility model are:

[0033] The utility model can be adjusted according to the installation height requirements of the fire protection pipe, and can assist workers to complete the high-altitude docking installation of two fire protection pipes. The operation is convenient and labor-saving, the installation efficiency is improved, the labor workload of workers is reduced, and the smooth installation and installation quality of the fire protection pipes are ensured, which is suitable for promotion.

[0034] The above are preferred embodiments of the present invention and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the present invention, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the present invention are within the protection scope of the present invention.
