Description

Technical Field

[0001] This utility model relates to the field of casting placement technology, and in particular to a long rod placement rack. Background Technology

[0002] Long rods machined by casting machinery are commonly used in the production of products such as drill collars. These long rods are typically stacked on wooden supports. This method of placement is problematic because, firstly, their proximity to the ground makes them susceptible to corrosion. Secondly, the lack of restraints after placement poses a safety risk. Finally, if these long rods are used to machine drill collars, their exterior is treated with anti-corrosion agents, and the current placement method easily damages the outer wall of the drill collar during storage. Utility Model Content

[0003] This utility model provides a long rod storage rack to overcome the shortcomings of the prior art and solve the problem of poor safety after placement, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A long rod support rack is provided, with long rods spaced apart along their length to improve stability. It includes long wooden blocks, each end of which is bolted to a pair of support rods. A rectangular sleeve is welded to the upper end of each support rod, and a crossbar is bolted inside the sleeve. Multiple support seats are movably mounted on the crossbar. The long rods are placed on these support seats for support, constraint, and safety. A central tie rod is welded between the support rods, and multiple vertical support rods are fixed to the tie rods with nuts. The lower ends of the vertical support rods are fixed to the long wooden blocks with nuts. The tie rods and vertical support rods enhance the stability of the support rods, thereby increasing the strength of the internal structure of the rack.

[0006] Furthermore, the support base includes a pair of sliding sleeves fitted onto the crossbar. A support vertical plate is welded to the upper end of each sliding sleeve. A constraint groove is formed with an opening at the upper end of the support vertical plate. The inner wall of the constraint groove is provided with a buffer pad, and the constraint groove has a V-shaped structure. The V-shaped constraint groove facilitates the restraint of long rods of different diameters, thereby ensuring the safety of the long rods after placement.

[0007] Furthermore, a V-shaped plate is provided directly above the supporting vertical plate. The two ends of the V-shaped plate are bent into wing plates. A U-shaped groove is formed with an opening on the outer end of the wing plate. An embedded hole is provided on the two inclined walls of the V-shaped plate. A rubber strip is provided in the embedded hole. The inner wall of the rubber strip abuts against the outer periphery of the long rod to constrain and fix the long rod.

[0008] Furthermore, the upper end of the supporting vertical plate is rotatably provided with a pair of concave heads, and a through shaft is inserted through the concave heads. The through shaft is inserted through the upper end of the supporting vertical plate, and the two ends of the through shaft are limited axially by cotter pins or nuts. A screw is welded to the concave head, and a pressing nut is threadedly connected to the screw. The screw is inserted into the U-shaped groove, and the lower end of the pressing nut acts on the upper wall of the wing plate. The screw, which can rotate around the axis of the through shaft, is conveniently inserted into the U-shaped groove. When it is in a vertical state, the V-shaped plate ensures the constraint effect of the long rod by tightening the pressing nut.

[0009] Furthermore, a pressure ring is fitted onto the screw, and a lower insertion rod is welded to the lower wall of the pressure ring. The lower insertion rod is inserted into the wing plate, and the screw is inserted into the wing plate to ensure that the screw is in a vertical position.

[0010] Furthermore, the support base is slidably mounted on the crossbar to facilitate density adjustment after the long rod is placed. In order to limit the position of the support base, a lower extension guide rod is welded to the lower end of the sliding sleeve. The lower end of the lower extension guide rod is provided with an end cap. A spring is sleeved on the lower extension guide rod. An upper top plate is sleeved on the lower extension guide rod. A positioning rod is threadedly connected to the upper top plate. The lower end of the spring abuts against the end cap, and the upper end of the spring abuts against the upper top plate. Multiple holes are opened on the lower wall of the crossbar, and the positioning rod is inserted into the holes.

[0011] Furthermore, a concave handle is welded to the top plate, which facilitates the removal of the positioning rod from the hole set in the lower wall of the crossbar, thereby making it easy to adjust the position of the support seat.

[0012] The advantages of the above technical solution are:

[0013] This utility model uses a combination of constraint grooves and V-shaped plates to clamp and fix long rods, ensuring the limiting effect after the long rods are placed, thus improving the safety of placement. In order to facilitate the placement of long rods in the constraint grooves, the V-shaped plates are detachably installed on the support vertical plates. Attached Figure Description

[0018] Figure 4 A magnified view of point B is shown. Detailed Implementation

[0019] like Figures 1-4 As shown, a long rod holder is characterized by being arranged at intervals along the length of the long rods 1. It includes long wooden blocks 2, with a pair of support rods 20 bolted to both ends of each long wooden block 2. A rectangular sleeve 23 is welded to the upper end of each support rod 20, and a crossbar 24 is bolted inside the rectangular sleeve 23. Multiple support seats are movably mounted on the crossbar 24. A central tie rod 21 is welded between the support rods 20, and multiple vertical support rods 22 are fixed to the central tie rod 21 by nuts. The lower ends of the vertical support rods 22 are fixed to the long wooden blocks 2 by nuts.

[0020] The support base includes a pair of sliding sleeves 3 fitted onto the crossbar 24. A support vertical plate 30 is welded to the upper end of the sliding sleeve 3. A constraint groove 31 is formed with an opening at the upper end of the support vertical plate 30. The constraint groove 31 has a V-shaped structure. A V-shaped plate 37 is provided directly above the support vertical plate 30. Wings 38 are bent at both ends of the V-shaped plate 37. A U-shaped groove 39 is formed with an opening at the outer end of the wing 38. A pair of concave heads 32 are rotatably provided at the upper end of the support vertical plate 30. A through shaft 33 passes through the concave heads 32. The through shaft 33 passes through the upper end of the support vertical plate 30. The two ends of the through shaft 33 are axially limited by cotter pins or nuts. A screw 34 is welded to the concave heads 32. A pressing nut 35 is threadedly connected to the screw 34. The screw 34 passes through the U-shaped groove 39. The lower end of the pressing nut 35 acts on the upper wall of the wing 38. A pressure ring 36 is fitted onto the screw 34, and a lower insertion rod 40 is welded to the lower wall of the pressure ring 36. The lower insertion rod 40 is inserted into the wing plate 38. A lower extension guide rod is welded to the lower end of the sliding sleeve 3. An end cap 41 is provided at the lower end of the lower extension guide rod. A spring 42 is fitted onto the lower extension guide rod, and an upper top plate 43 is fitted onto the lower extension guide rod. A positioning rod 44 is threadedly connected to the upper top plate 43. The lower end of the spring 42 abuts against the end cap 41, and the upper end of the spring 42 abuts against the upper top plate 43. A concave handle 45 is welded onto the upper top plate 43. Multiple holes are opened on the lower wall of the crossbar 24, and the positioning rod 44 is inserted into the holes.

[0021] In this embodiment, the operator first removes the V-shaped plate 37 located on the vertical support plate 30 along the same straight line, which is perpendicular to the length direction of the horizontal bar 24. Then, the long bar is transferred by a crane to the position directly above the constraint groove 31 of the vertical support plate 30 along the same straight line, and then the long bar is moved downward and placed in the constraint groove 31.

[0022] Next, place the previously disassembled V-shaped plates 37 on top of the long rod, and then rotate the screw 34 upward so that the screw 34 is located in the U-shaped groove 39. Then, put the pressure ring 36 on the screw 34 and insert the lower insertion rod 40 into the corresponding through hole on the wing plate 38. Then, the operator screws the lower pressure nut 35 on the screw 34 and makes the lower wall of the V-shaped plate 37 fit tightly against the outer periphery of the long rod by screwing the lower pressure nut 35.

[0023] Finally, the long rod is dragged by the crane to move it along the length of the crossbar 24 to the designated position. During the movement, the upper top plate 43 is pulled downwards. When the positioning rod 44 is aligned with the hole, the pulling force on the upper top plate 43 is released, and the positioning rod 44 is then inserted into the hole. After that, the connection between the long rod and the crane is disconnected.
