Description

Technical Field

[0001] This invention relates to the field of construction site pipe placement rack technology, specifically a construction site prefabricated pipe material placement rack. Background Technology

[0002] Pipe racks are shelves or supports used for storing and organizing pipe materials, and are widely used in construction sites, warehouses, manufacturing plants, and other places. Their main purpose is to maintain the orderly arrangement of pipes for easy access and management.

[0003] For example, CN 107284484 A discloses a special pipe placement rack for construction sites, including an L-shaped placement rack body. Two or more support plates are fixed at the inner right angle of the placement rack body, with each layer consisting of at least two support plates. A first screw connects the right end face of each support plate to the placement rack body. An arc-shaped pipe positioning groove is provided on the surface of each support plate. Two guide wheels are symmetrically arranged near the right side of the bottom of the placement rack body. A threaded pipe sleeve is provided near the left side of the bottom of the placement rack body, and a threaded rod is fitted inside the threaded pipe sleeve. The lower end of the threaded rod extends to the outside of the threaded pipe sleeve, and a pad is provided at the lower end of the threaded rod. This device can arrange various types of pipes in an orderly manner. Furthermore, this device is movable and can be moved to a closer location as needed for pipe installation, facilitating installation, effectively storing pipes, and preventing pipe damage.

[0004] However, when placing pipes using the aforementioned placement rack, it is necessary to disassemble the rack after it is completed on the construction site and transfer it to the next construction site. This requires quick installation and disassembly of the rack. Existing placement racks are either welded as one piece or have individual components fixed with bolts, making disassembly and installation difficult. Therefore, a site-prefabricated pipe material placement rack is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a construction site prefabricated pipe material placement rack to address the shortcomings of the prior art.

[0018] Preferably, one side of the bidirectional threaded rod is provided with an internal hexagonal groove, and the side push plate is provided with an adjustment hole, and the bidirectional threaded rod rotates within the adjustment hole.

[0019] Preferably, the tops of the two columns are provided with an adjustment mechanism and a pick-and-place mechanism. The pick-and-place mechanism is used to assist in picking up and placing the pipe, and the adjustment mechanism is used to adjust the pick-and-place angle of the pick-and-place mechanism to assist the pick-and-place mechanism in picking up and placing the pipe.

[0020] The adjustment mechanism includes:

[0021] The top connecting rod is installed at both ends inside the column;

[0022] Two adjusting rods are hinged in the middle to the top connecting rod and are symmetrically arranged, with their bottoms movably inserted into the movable holes of the top connecting rod.

[0023] Preferably, the adjustment mechanism further includes:

[0024] Two wedge-shaped blocks are set at the bottom of the top connecting rod and fit against the bottom outer wall of the adjusting rods on both sides, for adjusting the opening angle between the two adjusting rods;

[0025] An electric actuator, mounted at the bottom of the top connecting rod, has its output end connected to the wedge block and is used to move the wedge block.

[0026] Preferably, the picking and placing mechanism includes:

[0027] The motor is mounted on the top of the top connecting rod, and a rope drum is installed at its output end;

[0028] A guide wheel is installed at one end of the adjusting rod, and a steel wire rope is wound around the outer wall of the rope drum, and the steel wire rope is also wound around the outer wall of the rope drum;

[0038] A swing stop lever is rotatably connected to a stop lever, and its bottom extension is located on the inner wall of the stop lever and swings.

[0039] A spring is installed on the inner wall of the stop lever and fits against the extension of the swing stop lever to limit the swing of the swing stop lever.

[0040] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0041] 1. This prefabricated pipe material placement rack at the construction site features a quick-release installation mechanism. The placement rod can be placed on the base plate and quickly fixed using an elastic telescopic rod. Simultaneously, a horizontal connecting plate can be quickly inserted into two uprights, thus achieving the purpose of rapid installation of the placement rack. Furthermore, by simply rotating the bidirectional threaded rod, the placement rod can be pulled directly to achieve quick disassembly and reuse. This allows for rapid installation and disassembly when placing various pipe materials, facilitating their turnover.

[0042] 2. The prefabricated pipe material placement rack at this construction site uses an adjustment mechanism and a sampling mechanism. Two wedge blocks move to abut against the bottom of the adjustment rod to change the opening angle between the two adjustment rods, thereby adjusting the gripping position. At the same time, the steel wire rope is wound and unwound on the rope drum to grip pipes at different heights.

[0043] 3. The prefabricated pipe material placement rack at this construction site, through its gripping mechanism, uses rotatable claws to grip pipes of different diameters. At the same time, tension springs and limit blocks are used to pull and limit the two claws against each other, improving its stability when suspended and moved after gripping.

[0044] 4. The prefabricated pipe material placement rack at this construction site, through the setting of a stop mechanism, can restrict the movement of pipes placed on the placement rod by using a stop bar, preventing them from detaching from the placement rod. At the same time, after grabbing the pipe, when the pipe hits the swing stop bar, the swing stop bar can deflect, thereby reducing the impact force on the stop bar and improving the stability of the placement rack.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Please see Figure 1-8 One embodiment of the present invention is: a construction site prefabricated pipe material placement rack, comprising two uprights 1, and further comprising:

[0056] Multiple placement rods 2 are connected to the outer wall of the column 1 via quick-release installation mechanism 4, and are used to place pipes 9.

[0057] Two horizontal connecting plates 3 are inserted into the two columns 1 at both ends to fix the columns 1 horizontally.

[0058] The quick-release installation mechanism 4 includes:

[0059] Two base plates 41 are fixedly connected to the front and back of the column 1 respectively, for placing the placement rod 2;

[0060] Two side fixing plates 44 are respectively connected to the left and right sides of the column 1 and connected to the base plate 41;

[0061] The quick-release box 42 is connected to the top of the base plate 41, and each quick-release box 42 has two elastic telescopic rods 43 installed inside. The movable end of the elastic telescopic rod 43 is inserted into the through hole opened on the placement rod 2 to fix the placement rod 2.

[0062] The quick-release installation mechanism 4 also includes:

[0063] Two side push plates 45, with push blocks 48 connected to their inner sides, and movably connected to the inner wall of the column 1;

[0064] The bidirectional threaded rod 49 is installed in the middle of the column 1, and its two ends are threaded to the push blocks 48 on both sides, which are used to push the push blocks 48 to move.

[0065] Multiple limiting posts 47 are fixedly connected to the side fixing plate 44 and move within the limiting holes of the side push plate 45;

[0066] Multiple release levers 46 are fixedly connected to the side push plate 45, and movably pass through the side fixing plate 44 to contact one end of the elastic telescopic rod 43, which is used to push the elastic telescopic rod 43 inward to release the fixation of the placement rod 2.

[0067] The bidirectional threaded rod 49 has an internal hexagonal groove on one side, and an adjustment hole is provided on the side push plate 45. The bidirectional threaded rod 49 rotates within the adjustment hole.

[0068] Working principle: During installation, simply place the two placement rods 2 directly between the bottom plate 41 and the two side push plates 45. After contacting the elastic telescopic rod 43, the rods 2 are penetrated and run through the placement rod 2 and the side push plate 45, thus quickly fixing the placement rod 2. Then, the two horizontal connecting plates 3 are horizontally connected to the two columns 1 to achieve horizontal stability and fast installation.

[0069] When quick disassembly is required, simply connect an Allen wrench to the Allen socket groove and rotate the double-threaded rod 49 to push the push blocks 48 on both sides to move simultaneously, thereby moving the side push plates 45 on both sides. At the same time, by pushing the release rod 46 inward, the compression elastic telescopic rod 43 is moved inward and disengaged from contact with the side fixing plate 44. Meanwhile, the arc-shaped end of the elastic telescopic rod 43 can disengage from the placement rod 2 when it is pulled, thereby releasing the fixation and achieving the purpose of quick disassembly.

[0070] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the top of the two columns 1 is provided with an adjustment mechanism 5 and a pick-and-place mechanism 6. The pick-and-place mechanism 6 is used to assist in picking up and placing the pipe 9, and the adjustment mechanism 5 is used to adjust the pick-and-place angle of the pick-and-place mechanism 6 to assist the pick-and-place mechanism 6 in picking up and placing the pipe 9.

[0071] Adjustment mechanism 5 includes:

[0072] The top connecting rod 51 is installed at both ends inside the column 1;

[0073] Two adjusting rods 52 are hinged in the middle to the top connecting rod 51 and are arranged symmetrically, with their bottoms movably inserted into the movable holes of the top connecting rod 51.

[0074] The regulating mechanism 5 also includes:

[0075] Two wedge-shaped blocks 53 are set at the bottom of the top connecting rod 51 and fit against the bottom outer wall of the adjusting rods 52 on both sides, for adjusting the opening and closing angle between the two adjusting rods 52;

[0076] An electric push rod 54 is installed at the bottom of the top connecting rod 51, and its output end is connected to the wedge block 53 to push the wedge block 53 to move.

[0077] The picking and placing mechanism 6 includes:

[0078] Motor 61 is mounted on the top of top connecting rod 51, and a rope drum 62 is mounted on its output end;

[0079] Guide wheel 64 is installed at one end of adjusting rod 52. Wire rope 63 is wound around the outer wall of the rope drum 62, and the wire rope 63 is also wound around the outer wall of the rope drum 62.

[0080] The end of the wire rope 63 is equipped with a gripping mechanism 7 for gripping the pipe 9.

[0081] Working principle: When picking up and placing pipes, the electric push rod 54 is activated. When it extends and retracts outward, it pushes the two wedge blocks 53 to move, changing the opening and closing angle between the two adjusting rods 52. This allows for adjustment of the position of the guide wheels 64 on both sides, enabling the picking and placing of pipes 9 placed at different positions on the placement rod 2.

[0082] At the same time, the motor 61 drives the rope drum 62 to rotate, which in turn drives the wire rope 63 to rotate, and transmits the rotation through the guide wheel 64, thereby gripping the pipes 9 at different placement heights.

[0083] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the gripping mechanism 7 includes:

[0084] Connecting rod 71 is attached to the end of wire rope 63;

[0085] Multiple grippers 72 are arranged symmetrically in front and behind and left and right. The two inner grippers 72 are fixedly connected to the outer wall of the connecting rod 71, and the two outer grippers 72 are rotatably connected to the outer wall of the connecting rod 71, which are used to grip the pipe 9 when opening and closing.

[0086] A tension spring 73 is connected between the front and rear grippers 72 and is used to reset the relative movement of the two grippers 72;

[0087] The limiting block 74 is movable through the outer jaw 72 and inserted into the inner jaw 72 to prevent the jaw 72 from loosening when it is gripping.

[0088] The placement rods 2 on the front and rear sides of the column 1 are installed in a stepped manner, and the end of the placement rod 2 away from the column 1 is provided with a blocking mechanism 8 to prevent the pipe 9 from detaching from the placement rod 2.

[0089] Working principle: After lowering to a suitable height, the clamp 72 contacts the pipe 9, and the movable clamp 72 is pulled to rotate and grip the pipe 9. At the same time, the pipe is reset and fixed under the action of the tension spring 73, and then the limit block 74 is used to further fix it to prevent it from loosening during suspension.

[0090] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the blocking mechanism 8 includes:

[0091] The bottom of the stop lever 81 is inserted into the placement lever 2 to prevent the pipe 9 from disengaging from the placement lever 2;

[0092] The swing lever 82 is rotatably connected to the lever 81, and its bottom extension is located on the inner wall of the lever 81 and swings.

[0093] A spring 83 is installed on the inner wall of the stop lever 81 and fits against the extension of the swing stop lever 82 to limit the swing of the swing stop lever 82.

[0094] Working principle: When the pipe 9 is placed on the placement rod 2, it is blocked by the stop bar 81 to prevent the pipe 9 from rolling on the placement rod 2 and falling off the placement rod 2. At the same time, when the pipe 9 is grabbed, it will deflect after hitting the swing stop bar 82, thereby reducing the impact force on the stop bar 81 and improving the stability of the placement frame.
